Full textAbstract:
This annual dioecious weed was found in 2002 and 2003 infesting soybean fields in southwestern Ontario, and it was collected in 1992 from waste places in British Columbia. It is a major weed problem in field crops in the mid-western United States, where it has become increasingly difficult to control during the past 10 yr. Morphological differences between Amaranthus tuberculatus var. rudis and var. tuberculatus are presented. A review of the biological information published is provided. Plants exhibit high phenotypic plasticity and genetic variability. Emergence is prolonged, growth rapid, and female plants produce a large number of viable seeds that contribute to a persistent seed bank. Amaranthus tuberculatus var. rudis has developed multiple resistance to triazine and acetolactate synthase- and protoporphyrinogen-inhibiting herbicides. Airborne pollen can travel significant distances and A. tuberculatus var. rudis may hybridize with other noxious Amaranthus spp. transferring herbicide resistance or other traits. Key words: Amaranthus tuberculatus var. rudis, AMATA, Amaranthus rudis, common waterhemp, weed biology, invasive alien

Full textAbstract:
Quassia amara is a plant of the family Simaroubaceae of Northern Brazilian origin.Its use in folk medicine is widespread, especially as an antiparasitic, antifungal and antibacterial agent. Our purpose was testing a Quassia amara ethanol wood extract (QWE) on various parasites, fungi and bacteria which had not been previously screened for this ingredient. QWE was found to have a strong antiparasitic effect on Demodex spp by counting the number of mites extracted from biopsies of pustules of patients with erythematotelangiectatic and papulopustular subtypes of rosacea along a topical treatment with 4% QWE, these numbers reaching their physiological value after a 42-day course. In Vitro testing of this extract on cultures of Trichomonas vaginalis collected from symptomatic patients showed a rapid inhibition of the growth of the trophozoites after 48 hours of contact. QWE also showed a marked antifungal activity on Candida spp (namely C. albicans, C. parapsilosis, C. glabrata and C. krusei, the latest at a lesser extent, and Malassezia furfur isolated from samples of infected patients, inhibiting the growth of fungi in both a time- and dose-dependent manner.The antibacterial activity of QWE was demonstrated in cultures of P. acnes and coagulase- positive Staphylococci where the growth of the bacteria was reduced in a significant manner (p<0.05) and at a lesser extent in cultures of coagulase-negative Staphylococci where the growth inhibition was not statistically significant. Contrarily, QWE had no effect on the growth of Chlamydia trachomatis, but uniquely altered the morphology and quantity of chlamydial inclusions.To the best of our knowledge, this is the first time that QWE is shown to have antiparasitic activity on Trichomonas vaginalis and Demodex spp, an antifungal activity on Malassezia furfur and Candida spp and an antibacterial activity on P. acnes

Full textAbstract:
This paper is an ethnobotanical review of wild edible plants gathered for consumption from the 19th century to the present day, within the present borders of Slovakia. Twenty-four sources (mainly ethnographic) documenting the culinary use of wild plants were analysed. The use of 106 species (over 3% of the Slovak flora) has been recorded. Nowadays most of them are no longer used, or used rarely, apart from a few species of wild fruits. The most frequently used plants include the fruits of <em>Rubus idaeus</em>, <em>Fragaria </em>spp., <em>Rubus </em>subgenus <em>Rubus</em>, <em>Vaccinium myrtillus</em>, <em>V. vitis-idaea</em>, <em>Fagus sylvatica</em>, <em>Corylus avellana</em>, <em>Prunus spinosa</em>, <em>Pyrus </em>spp., <em>Malus </em>spp., <em>Crataegus </em>spp. and the leaves of <em>Urtica dioica</em>, <em>Rumex acetosa</em>, Chenopodiaceae species, <em>Cardamine amara</em>, <em>Glechoma </em>spp., <em>Taraxacum </em>spp. and <em>Oxalis acetosella</em>. The most commonly used wild food taxa are nearly identical to those used in Poland, and the same negative association of wild vegetables with famine exists in Slovakia, resulting in their near complete disappearance from the present-day diet.

Full textAbstract:
AbstractPredatory arthropods were sampled in high-maintenance Kentucky bluegrass lawns (lawns under commercial lawn care), low-maintenance Kentucky bluegrass lawns (under minimal care), and low-maintenance tall-fescue lawns. In general, tall fescue supported fewer predators than Kentucky bluegrass, specifically the families Erigon-idae, Linyphiidae, and Carabidae. Populations of Erigonidae, Linyphiidae, and Carabidae were lower in high-maintenance bluegrass than in low-maintenance bluegrass. The carabids Amara cupreolata Putzeys, Agonum punctiformum (Say), and Harpalus (Pseudopkonus) spp., and a staphylinid, Philonthus sp., were particularly uncommon in high-maintenance sites. Hierarchical classification of sites suggested that the structure of the staphylinid and carabid communities differs in tall fescue and Kentucky bluegrass turf, and differs in high- and low-maintenance bluegrass.

Full textAbstract:
Carabidae (Coleoptera) were monitored from pitfall trap catches in four soybean cropping systems in Westmoreland Co., Virginia during the summer of 1982. Harpalus pensylvanicus DeGeer, Poecilus chalcites Say, Amara spp., and Agonum octopunctatum Fabricius were the most commonly encountered among the 39 species collected. These four species were more abundant in drill-planted and double-cropped soybean fields which were conservation tillage systems as compared to conventionally plowed fields. Significantly more species per field and more carabids per trap were found during June than in later summer months. The Shannon-Weaver diversity and Berger-Parker dominance indices showed no significant differences in species diversity among the cropping systems. The total number of carabids present in soybeans is more important in comparisons than either species number of species evenness.

Full textAbstract:
Trichoptera Kirby, 1813, is the second order of Insecta Linnaeus, 1758 (after Hemiptera Linnaeus, 1758) to be found hosting temnocephalans anywhere in the world. Temnocephalans were found on caddisfly larvae from the genus Barypenthus Burmeister, 1839 while collecting aquatic insects from a small creek in Serra do Cipó, State of Minas Gerais, Brazil. Thirty-six larvae and their cases were examined, of which 20 (55.5%) were positive for specimens of Temnocephala Blanchard, 1849. Juvenile and adult temnocephalans were always devoid of body pigmentation and were living on the dorsal and ventral body surfaces of the larvae. The eye pigmentation was deep red, disappearing in specimens fixed in ethanol. Eggs were found in larger numbers on the dorsal thoracic segments. The most distinctive characters of the temnocephalans found on caddisfly larvae were found in the cirrus and the vagina. The comparison of the general anatomy and, in particular, the morphology of the cirrus and the vagina with those of Temnocephala curvicirri Amato & Amato, 2005, described from aquatic heteropterans (Belostoma spp.), from the State of Rio Grande do Sul, which is revisited, showed that although these characters are of the same type and nature they are not equal, differing primarily in size and morphology of the cirrus and the muscularity of the middle portion of the vagina. The egg deposition sites are different and the cirrus and the vagina are characterized for the first time as being ‘complex’.

Full textAbstract:
Background: Irritable bowel syndrome (IBS) is a functional disorder without any pathological alteration, in which the alterations of the Candida/Saccharomyces ratio of the gut microbiota, the balance of pro and anti-inflammatory cytokines and the brain-gut-microbiome axis are important for the development and progression of IBS. The aim of the study was to identify natural products, including essential oils or hydrolates, which were contextually harmless for the gut beneficial strains (e.g., Saccharomyces spp.) but inhibitory for the pathogenic ones (Candida spp.). Methods: The effectiveness of 6 essential oils and 2 hydrolates was evaluated using microbiological tests, carried out on 50 clinical isolates (Candida, Saccharomyces and Galattomyces species) and 9 probiotic strains (Saccharomyces cerevisiae, Lactobacillus species, Akkermansia muciniphila and Faecalibacterium prausnitzii) and immunological and antioxidant assays. Results: The study led to a mixture based on a 1/100 ratio of Citrus aurantium var. amara essential oil / Vitis vinifera cv Italia hydrolate able to contextually reduce, in a concentration-dependent manner, the ability of Candida species to form hyphal filaments and have an interesting immunomodulatory and anti-oxidant action. This mixture can potentially be useful in the IBS treatment promoting the restoration of the intestinal microbial and immunological balance.

Full textAbstract:
The Podocarpaceae are the most morphologically diverse of conifer families. A taxonomic trend has resulted in recognising this diversity via smaller generic groupings, including several monotypes. A phylogenetic assessment of the monotypic genera Sundacarpus and Manoao was conducted employing maximum parsimony the analysis of sequence data from 18S-ribosomal DNA from 34 gymnosperm taxa, including 29 Podocarpaceae. In resulting trees, there is high bootstrap support for Podocarpaceae, including Phyllocladus, but the order of deep branches within the family is equivocal. Prumnopitys (Sundacarpus) amara (Blume) de Laub. and four other Prumnopitys spp. comprise a clade with a bootstrap value of 100%, supporting the retention of Sundacarpus as a section of Prumnopitys. Lagarostrobos franklinii (Hook.f.) Quinn and L. (Manoao) colensoi (Hook.) Quinn comprise a clade with equivocal bootstrap support, echoing previous results from parsimony analysis of morphological data. A conservative approach (i.e. one avoiding unnecessary monotypes) favours the retention of L. colensoi in Lagarostrobos, pending further evidence of relationships within the group.

Full textAbstract:
In this paper we present an updated checklist of thallus-forming Laboulbeniomycetes (Ascomycota, Pezizomycotina), that is, the orders Herpomycetales and Laboulbeniales, from Belgium and the Netherlands. Two species are newly described based on morphology, molecular data (ITS, LSU ribosomal DNA) and ecology (host association). These are Hesperomyces halyziae on Halyzia sedecimguttata (Coleoptera, Coccinellidae) from both countries and Laboulbenia quarantenae on Bembidion biguttatum (Coleoptera, Carabidae) from Belgium. In addition, nine new country records are presented. For Belgium: Laboulbenia aubryi on Amara aranea (Coleoptera, Carabidae) and Rhachomyces spinosus on Syntomus foveatus (Coleoptera, Carabidae). For the Netherlands: Chitonomyces melanurus on Laccophilus minutus (Coleoptera, Dytiscidae), Euphoriomyces agathidii on Agathidium laevigatum (Coleoptera, Leiodidae), Laboulbenia fasciculata on Omophron limbatum (Coleoptera, Carabidae), Laboulbenia metableti on Syntomus foveatus and S. truncatellus (Coleoptera, Carabidae), Laboulbenia pseudomasei on Pterostichus melanarius (Coleoptera, Carabidae), Rhachomyces canariensis on Trechus obtusus (Coleoptera, Carabidae), and Stigmatomyces hydrelliae on Hydrellia albilabris (Diptera, Ephydridae). Finally, an identification key to 140 species of thallus-forming Laboulbeniomycetes in Belgium and the Netherlands is provided. Based on the combined data, we are able to identify mutual gaps that need to be filled as well as weigh the impact of chosen strategies (fieldwork, museum collections) and techniques in these neighboring countries. The aim of this work is to serve as a reference for studying Laboulbeniomycetes fungi in Europe.

Abstract Objectives The main shelf-stable product of yam is the traditional yam flour (elubo), Yams (Dioscorea spp.) which are regarded as traditional foods are consumed in various ways but majorly consumed as yam flour in the south west region of Nigeria. This study investigated the physical, functional and sensory properties and anti-nutrients contents of peeled and unpeeled yam flour. Methods Yam bought in the popular market production procedures were followed, washing, peeling and slicing, parboiling, steeping. draining, drying, milling, and packaging for peeled yam and unpeeled yam peeling was not included in the process, the two samples were analyzed chemically according to the official methods of analysis described by the Association of Official Analytical Chemist as well as sensory evaluation. Results The results of the study confirmed the significant difference in the micro nutrients content of peeled and unpeeled yam flour in fats and water soluble vitamins respectively (K µg/100 g = 6.97,11.83, Fe(mg/kg) = 95.2, 126.9, minerals content Zn(mg/kg) 13.48, 22.92, Fe(mg/kg) 95.2126.9 and anti-nutrient properties of the ‘Amala’ made from the two products (peeled and unpeeled yam flour) the percentage of Tannin 0.0023, 0.0010 and Hydrocynaide (mg/kg) 0.92, 1.01.The proximate analysis of unpeeled yam four indicated a high value than that of peeled yam flour in protein (2.47, 2.28), fats (1.86, 0.54), ash (3.59, 2.32), and fibre (3.09, 1.31) of both samples respectively but the energy content derived from the ‘amala’ made from unpeeled yam flour is lesser to that of peeled yam flour. Significant exist between the two samples in sensory evaluation of taste, texture, color, mouldability, aroma and general acceptability. Conclusions The result shown that the consumption of unpeeled yam flour can be useful in treatment of nutrient deficiencies diseases. Funding Sources Self.

Full textAbstract:
Yams (Dioscorea spp) are among the oldest food crops. It is estimated that after six months of storage up to 56% of the crop is lost to rot. In Nigeria, fresh yam tubers are used for production of Elubo (yam flour) for preparation of amala, as it is called among the Yoruba in Western Nigeria, and akwunaji in the east of the River Niger. Many researchershave emphasized the importance of microbial rotting in causing storage losses. This study evaluated the effect of yam rot on the nutritional values of Fusarium infected yam tubers.Tubers from two yam (Dioscorea rotundata Poir.)varieties-Nwopoko and TDr95/19177-were infected with Fusarium nygamai pure culture and stored for 12 weeks, after which the tubers were used to produce yam flour and were analyzed for their nutrient composition comprising: dry matter/ moisture content, ash, total sugar, starch, amylose, vitamin C, protein and tannins. Wholesome yams of the same varieties were also used to produce yam flour and equally evaluated for the same nutrients. Infection with Fusariumnygamai led to a significant reduction (p<0.05) in the nutrient composition of the infected yam flour compared with those ofwholesome samples. Vitamin C content reduced from 41.10 to 27.26 (mg/100g) in variety Nwopoko and 36.30 to 30.53 (mg/100g); in variety TDr95/19177. Corresponding values for protein content was from 5.05 to 4.60% and 4.93 to 4.62%; Ash Content from 1.32 to 1.30% and 1.36 to 1.24%; Total Sugar Content from 5.34 to 5.20% and 5.21 to 5.02%; Starch 78.71 to 77.61 and 89.28 to 81.53%; Amylose from 29.95 to 28.87% and 30.01 to 27.95%. However, an increase in the tannin content – (1.84 and 1.94 mg/g) as against (0.31 and 0.26 mg/g) in Nwopoko and TDr 95/19177 varieties respectively was observed. The increase in the tannin content implies an increase in the antinutrient composition. The tendency to produce Elubo used for preparation of amala with rotten yam (possibly Fusarium infected) should be discouraged.

Pleurotus spp. have the ability to grow on a wide variety of lignocellulosic materials, which opens up a range of options to be explored. The use of locally available residues and native strains can reduce production costs, thus making fungiculture a potential economic activity in developing regions, such as northern Brazil. The aim of this research was to compare the production and nutritional characteristics of different strains of P. ostreatus, cultivated on lignocellulosic residues available in Amazonas state, Brazil. The native (474 and 1467) and commercial (542 and 885) strains were cultivated in marupá (Simarouba amara) and pine (Pinus sp.) sawdust, açaí (Euterpe oleracea) seeds and elephant grass (Pennisetum purpureum Schum.) straw. Productivity was evaluated according to biological efficiency, yield and loss of organic matter. Some physicochemical and nutritional parameters were also evaluated. In general, among the residues evaluated for mushroom cultivation, the elephant grass substrates (EG) showed better physicochemical properties in terms of moisture, ash content (minerals), hemicellulose and lignin. Additionally, the EG-based substrate resulted in the best productive parameters (yield and EB) for all strains studied, with emphasis on strain 1467, which is native to the Amazon. The basidiocarps of the native strains (474 and 1467) presented a nutritional composition that is similar to the commercial strains (885 and 542), and the mushrooms grown in EG-based residue, in general, presented the best nutritional compositions. Thus, strain 1467 of Pleurotus ostreatus, native to the Amazon, shows promise for commercial purposes, when cultivated in elephant grass residue.

Blood 106, no. 11 (November 16, 2005): 2720. http://dx.doi.org/10.1182/blood.v106.11.2720.2720.
Full textAbstract:
Abstract CCAAT displacement protein (CDP) is a highly conserved, ubiquitously expressed homeodomain protein with extensive homology to the Drosophila cut protein. CDP contains three highly conserved DNA-binding repeats called cut repeats, as well as a conserved homeodomain sequence. CDP is a transcriptional repressor of several developmentally regulated genes involved in neutrophil maturation, including the phagocyte-specific cytochrome heavy chain gene, gp91-phox, and CCAAT enhancer binding protein epsilon (C/EBPε ). It also represses expression of neutrophil secondary granule proteins (SGPs), including LF, which are downstream targets of C/EBPε . We have previously shown that CDP binds to and represses both the C/EBPε and lactoferrin (LF) gene promoters thereby preventing expression of secondary granule proteins (SGPs) both directly and indirectly. Additionally, we have demonstrated that overexpression of CDP represses expression of SGPs in 32Dcl3 cells, an IL-3 dependent murine myeloid cell line that undergoes differentiation in response to IL-3 withdrawal and G-CSF stimulation. Conversely, knocking down CDP expression by RNA interference in 32D cells upregulates levels of LF mRNA in uninduced cells. NB4 cells are an acute promyelocytic cell line that contains the t(15;17) PML-RARα translocation and can be induced toward neutrophil maturation with all-trans-retinoic Acid (ATRA). We have previously demonstrated that NB4 cells uniformly fail to express LF and all the SGP genes upon ATRA induction. In further studies, we showed that this failure of expression occurs despite appropriate binding of C/EBP factors known to upregulate SGP expression. We further demonstrated persistent binding of CDP to the LF promoter in NB4 cells upon ATRA induction, suggesting that failure of LF expression was due to persistent binding of CDP rather than a failure of C/EBP transactivation. In order to test this hypothesis, we knocked down CDP expression in NB4 cells using short hairpin RNA (shRNA) constructs and examined the effect of reduced CDP levels on SGP expression. ShRNA CDP constructs were introduced into NB4 cells by nucleofection using an Amaxa® nucleofector. Half the transfected cells were induced with ATRA, while the other half remained uninduced. After 24-hours of induction, total RNA was extracted from the cells and RTqPCR performed to assess the levels of SGP mRNA. We demonstrate that decreased CDP expression in ATRA- induced NB4 cells is sufficient to restore LF, collagenase, and gelatinase expression in the leukemic cell line. SGP expression remains absent in uninduced CDP-shRNA NB4 cells, as well as in both uninduced and induced cells transfected with an empty vector. Our observations reaffirm the critical role played by CDP in regulating the expression of LF and other SGP proteins during neutrophil development. How the PML-RARα gene product functions to alter CDP activity in NB4 cells at the molecular level, thereby restricting SGP expression, is currently being addressed.

La presente investigación analiza la distribución, abundancia y composición de tropas del mono aullador negro, Alouatta pigra, en la eco región Lachuá. Los remanentes boscosos donde se localizaron los monos variaron en cuanto al tamaño, el tipo de cobertura vegetal y la distancia de aislamiento entre cada uno de los mismos. Además se consideró el efecto de la "representación" de los habitantes de las comunidades con respecto al mono aulladornegro en la abundancia y distribución de estos primates. En un total de L067 horas de búsqueda, se pudieron observar 414 individuos de los cuales 403 (97%) conformaron 80 tropas y 11 (3%) conformaron grupos extra tropa, individuos solitarios y una hembra adulta del mono aullador de manto, A. palliata, que era parte de una tropa de A. pigra. Se observó que la fragmentación del hábitat modifica el hábitat potencial que los monos aulladores negros pueden utilizar al limitar la distribución de los individuos a los pocos remanentes de bosque que persisten en el área de influencia y al PNLL. Dichos remanentes frecuentemente se encuentran aislados. Se detectó una mayor cantidad de individuos y de tropas en los parches cercanos a los cerros lo cual posiblemente está relacionado a una mayor abundancia del árbol de ramón ( Brosimum spp.) cerca de sitios arqueológicos en el área. Además se observó abundancia de los árboles alimenticios de tamarindo (Dialium guianense) y amate ( Ficus spp.) en dicha área. El tamaño promedio de las tropas en los parches (áreas boscosas menores a 4 km2) fue de 5.19 (±1.97 con rango de 1 1 a 2 individuos), en los cerros (área de 18.09 km2) fue de 5.35 (±1.70 con rango de 8 a 3) y en el PNLL (área de 31.74 km2) fue de 3.89 (±1.33 con rango de 6 a 3). El promedio de los índices de densidad relativa poblacional fue de 13.01 ind/km2 en los parches y de 6.8 ind/km2 en los cerros. El índice de densidad relativa ecológica en el PNLL fue de 1.8 y en los parches se observó un rango de 1.04 a 700.67 ind/km2. La composición del total de tropas detectadas (N=80) es la siguiente: 34% de individuos machos adultos (N=136), 35% de hembras adultas (N=142), 6% de machos juveniles (n=24), 9% de hembras juveniles (N=34), 1 % de juveniles no sexados (N=5) y 15% de infantes (N=62). La proporción de individuos machos adultos fue más alta en áreas con menor densidad (cerros) y se observó una alta tendencia a tropas poligámicas y unimacho. El número de individuos de A. pigra detectados fue mayor en remanentes con cobertura vegetal bosque y en parches poco aislados (de 81 a 262 m de distancia).

Kwale forest reserve with gazetted area of 3km 2 in the present Delta state, south eastern Nigeria, is surrounded by numbers of adjoining communities such as Okpai, Umu-uzor, Ugbome, Nkwor, Amama and Asa. The fringe ecosystem is endowed with important conservation-status species like primate: Cercopithecus spp; family of artiodactyla, Tragelaphus scriptus, rodentia : Dendrohyrax arborea, Thryonomys swinderianus; carnivores Panthera leo, Vulpes pallida and numbers of avifauna species as well as reptilea. The natural high forest ecosystem consists of emergent trees, such as: Ceiba pentandra , Landolphia oweriensis ; the under storeys: Strychnos spinosa , Lindaclearia dentata and the surrounding inhabitant drawn most of their livelihood from the natural ecosystem like bush meat which provide protein, firewood, water for cooking and other basic necessities. The use of Kwale forest reserve and the surrounding ecosystem by the Independent Power Plant (IPP) for electricity generation will continue to contribute to the loss of most natural resource base (flora and fauna). Many of such developmental projects (eco-development) are executed daily in the country and have resultant ecosystem damage, species erosion and environmental degradation. The exploitation over past decades has left a wasteland with serious environmental problems. The percentage preference for hunting of primate, rodent, antelope and avifauna are 55%, 20%, 20%, 5%, respectively, while the preference for consumption of meat indicated that bush meat is mostly preferred (33.5%) by the inhabitants, compared to other conventional sources such as beef, pork, fish, and chicken with 20.6%, 10.5%, 25.6% and 10.0%, respectively. It is pertinent to note that strategic management will be needed to protect, sustain, and manage the Kwale forest reserve along side with IPP developmental concept, thus, there is a need for Environmental Impact Assessment (EIA) as a tool for decision makers as well as ecosystem managers. This is necessary for timely communication of information between the policy makers (government) and stakeholders conducting specific projects that have mutual benefits to the general public.

The success of learning can be achieved when the teacher can provide an engaging learning experience and engage students actively. This state of being can be created by applying innovative learning models. Unfortunately, many teachers have not designed innovative learning models and used them correctly. This program aims to train teachers in partner schools to work in lesson study groups so that teachers can (1) easily design innovative learning models, (2) be able to produce PBL-based lesson plans and other learning tools to support innovative learning. This activity will be held in August 2021 in counselling and practical work. The instrument used is an observation sheet to observe cooperation, communication, member roles and work completeness in lesson study activities, as well as the preparation of PBL-based tools with observational indicators, namely lesson plans arranged according to PBL syntax, the student worksheet triggers student activity, media attracts interest in learning and assessments in the HOTS category. Unstructured interviews were conducted as a complement to the data. Partners in this activity are all 60 SMP Negeri 4 Palu teachers, totalling 60 teachers. The observations show (1) teachers can work together and communicate well in designing innovative learning models according to the syntax in the lesson study team, and (2) teachers can produce PBL-based lesson plans and other learning tools that support innovative learning. The interview results inform that lesson study activities make it easier for teachers to design innovative learning. In addition, collaboration in lesson study can train teachers to produce better learning devices according to the learning model's needs. Cooperation in lesson study teams to design innovative learning models is important to continue and disseminate.

Abstract Pancreatic ductal adenocarcinoma lethality can be attributed to a combination of rapid metastatic dissemination and intrinsic resistance to conventional therapies. Our prior studies using single cell RNA-seq in pancreatic circulating tumor cells (CTCs) revealed that these “seeds of metastasis” had a biphenotypic state of both epithelial and mesenchymal features. This suggested that CTCs are highly plastic cells that exist in an intermediate state along epithelial (E) to mesenchymal (M) transition (EMT). Analysis of CTC markers in primary PDAC tumors revealed that this subpopulation of cancer cells was concentrated at the interface of tumor cells and stromal cancer associated fibroblasts (CAFs). To evaluate the contribution of CAFs in PDAC EMT plasticity, we utilized patient derived PDAC-CAF co-culture preclinical models demonstrating that PDAC EMT heterogeneity was modulated by the density of CAFs and partially driven by TGF-b secretion. Moreover, analysis of patient derived PDAC tumor spheres treated with FOLFIRINOX (FFX) demonstrated selection or induction of EMT changes that were also found in patient tumors that were resected after neoadjuvant FFX. Altogether, our collective work along with others demonstrates the importance of EMT plasticity in PDAC cell metastatic propensity and the ability to resist cytotoxic chemotherapy. A multi-institutional randomized Phase II trial supported by SU2C-Lustgarten Foundation evaluating the role of the TGF-b modulating activities of losartan on locally advanced PDAC response to chemotherapy and suppression of metastatic dissemination has neared completion. This 3 arm (n=40 per arm) trial of neoadjuvant FFX, FFX + losartan, or FFX+ losartan + nivolumab (anti-PD1). Here, we have performed EMT RNA in situ hybridization in all post-treatment resection specimens to determine if there is a difference in EMT proportions between the different arms of the study. As an orthogonal unbiased approach, we have utilized the NanoString GeoMx Digital Spatial Profiler whole transcriptome assay (18,000+ protein coding genes) on each of the resection specimens with analysis of the tumor cells, CAFs, and immune cell separately for multiple regions of interest in these specimens. This provides deeper molecular insight of the PDAC tumor cells that resisted neoadjuvant therapy, the changes in the surrounding CAFs, and the modulation of immune infiltrates that might differ between each arm of the study. We anticipate the results of the trial will be completed before the conference and initial correlative analysis of spatial transcriptomics and RNA-ISH will be presented.

Abstract Aberrant transcription of the repeat RNAs is a common feature in epithelial cancers including PDAC, but the function of these non-coding RNAs in cancer development is relatively unexplored. We have found that these repeat RNAs are sensed and replicate like retroviruses, and now have identified the ability of these viral-like elements to be transmitted from cancer cells through extracellular vesicles (EVs). PDAC-derived EVs applied to cancer-associated fibroblasts (CAFs) activates interferon-stimulated genes (ISGs) and is able to drive CAFs towards an inflammatory CAF (iCAF) phenotype with concordant loss of myofibroblast CAF (myCAF) marker genes. Using in-vitro transcription, we demonstrate that individual repeat RNAs (HSATII, HERVK (env), LINE-1 5’UTR and LINE-1 3’UTR) are sufficient to induce ISG response in CAFs with HSATII and HERVK (env) having the most potent ISG response. In contrast, PDAC cells were found to induce epithelial-mesenchymal transition (EMT) with loss of epithelial gene expression. To determine the potential sensor of HSATII repeat RNAs, we utilized CRISPR/Cas9 knockout of the viral RNA sensors RIG-I, MDA5, and MAVS in PDAC and CAF cells. Notably, these sensors were important for PDAC repeat RNA sensing and response, but not in CAF cells. Evaluating the innate immune pathway further downstream, we used genetic knockout of IRF3 with CRISPR/Cas9 knockout and find significant downregulation of key EMT genes that are shared with myCAF markers (ACTA2, FN1, SERPINE1). Interestingly, HSATII RNA activated IRF3 dependent EMT genes in PDAC cells, but induced IRF3 degradation in CAF cells that results in loss of myCAF gene expression. Furthermore, we found that conditioned media from HSATII transfected CAF activates EMT-related gene expression (ACTA2, FN1, SERPINE1) in PDAC cell lines, which indicates an cell extrinsic mechanism to augment EMT induction in PDAC cells. We utilized next generation spatial transcriptomic platforms NanoString GeoMx and CosMx to understand the spatial distribution of repeat RNAs in human PDAC tumors. We find that repeat RNAs can be found as a gradient from PDAC cells to the surround tumor microenvironment consistent with delivery of these RNA species. Analysis of over 300,000 individual cells in 3 PDAC tumor specimens, we find that high repeat PDAC cells have lost epithelial gene expression and high repeat CAFs have lost myCAF gene expression. Altogether, these findings support the “infection” of repeat RNAs disrupts cellular identity in both tumor cells and the CAF microenvironment as a mechanism for tumor progression.

Neste artigo apresento um estudo de caso sobre a paisagem linguística na fronteira entre as cidades de Tabatinga (Brasil) e Leticia (Colômbia), com base nos conceitos de paisagem linguística (Bloomaert, 2012; Shohamy, 2010; Cenoz y Gorter, 2006), superdiversidade (Bloomaert y Rampton, 2012; Vertovec, 2007) e metrolinguismo (Otsuji; Pennycook, 2010). Este estudo de caso utiliza como dados de análise imagens de placas e letreiros de estabelecimentos comerciais, localizados próximo ao marco de fronteira entre Brasil e Colômbia, fotografadas durante trabalho de campo nas cidades mencionadas e tem como objetivo pensar a paisagem linguística como um dos instrumentos que podem auxiliar no diagnóstico sociolinguístico dos repertórios comunicativos dos falantes de uma determinada comunidade e o status das línguas nesses territórios fronteiriços. Além disso, proponho pensar a paisagem como um importante recurso para a promoção do multilinguismo e das línguas autóctones invisibilizadas pela hegemonia das línguas oficiais dos países onde se desenvolve o presente estudo. Essa invisibilização é perceptível, conforme aponto no estudo, não apenas na paisagem linguística dessas cidades, mas também no sistema escolar municipal e estadual ao não se observar a presença dessas línguas nos currículos das escolas regulares, revelando a ausência de uma representação identitária e linguística de grupos étnicos que vivem nesse espaço.REFERÊNCIASBEN-RAFAEL, E.; SHOHAMY, E.; AMARA, M.

Full textAbstract:
Abstract Abstract 3896 Poster Board III-832 We previously reported the finding of significantly raised levels of mature microRNA 16 (miR-16) in CD34+ cells from PV patients (pts) (Guglielmelli P et al, ASH 2008, 179A). Mature miR-16 can derive from both miR-16-1 at chr13q14.3 and miR-16-2 at chr3q26.1, which differ in their precursor miRNA (pre-miR) sequence. To distinguish between either genes as a source of increased miR-16 levels we quantified each pre-miR in PV CD34+; we observed that the premiR-16-1/16-2 ratio decreased from 1.47± 2.38 in controls (ctr) to 0.52± 0.34 in PV (P<.001). To confirm the preferential expression of miR-16-2 we knocked-down miR-16-1 or miR-16-2 using specific siRNAs; in PV CD34+ treated with miR16-2 siRNA the miR-16 levels were 90±9% lower than in scramble-treated cells while miR16-1 siRNA caused only a 10±3% reduction (P <.01). Levels of miR-16 in PV CD34+ were not correlated to the JAK2V671F burden; also, there was no modification of miR-16 in JAK2V617F mutant HEL or UKE-1 cells after treatment with the JAK2 inhibitor AZD1480. These data suggested that the abnormally increased mature miR-16 in PV are largely derived from miR-16-2. To address underlying mechanisms we performed direct sequencing at the miR-16-1 and miR-16-2 regions without detecting sequence abnormalities; also we excluded gene copy number changes (SNP 6.0 array). The promoter of miR16-2 is not characterized yet, but recent data suggest that it might be the same of the structural maintenance of chromosomes-4 (SMC4) gene, to which miR16-2 is intronic. We have found a significant correlation between miR-16 and SMC4 mRNA levels in PV CD34+ (R=0.77, P<.001); furthermore, after induced erythroid differentiation of normal CD34+ a concurrent increase of miR-16 and SMC4 mRNA was observed, indirectly supporting a shared regulatory control. Methylation-specific PCR and sequencing at upstream CpG-rich regions discovered that PV patients had unmethylated CpGs compared to control cells, suggesting that methylation may concur to miR-16-2 regulated expression. To evaluate involvement of miR16 in abnormal erythropoiesis of PV, we first analyzed the kinetics of miR-16 during erythroid differentiation of CD34+. Levels of miR-16 steadily increased from day 6, when progenitors were switched from proliferative to differentiative phase, up to day 12-14 and, at any time point considered, those measured in PV cells were significantly greater than in ctrs (P= .01). Also, a time-dependent increase of miR16 paralleling the transcription of beta-globin mRNA was observed in hydroxyurea or Na-butyrate treated K562 cells. Then we over-expressed (Amaxa) mature miR16 in normal CD34+ at day 6 of culture, and found that the percentage of CD36+/GPA+ cells increased from 13.6±4.8% in scramble to 28.8±11.3% (P<.05); notably, even in the absence of EPO, some GPA+ cells were generated from miR-16-transduced CD34+. Furthermore, normal CD34+ cells transfected with miR-16 produced significantly increased number of CFU-e and BFU-E (174±100 and 1283±250/103 CD34+) compared to scramble cells (105±90 and 733±90; P<.01) while myeloid colonies were unchanged. A genome-wide expression profiling in normal CD34+ transfected with miR-16-2 siRNA discovered 618 genes significantly de-regulated, among which genes involved in erythroid differentiation such as NFE2, MYB, FGFR2, HLF, GATA-1 and globin family genes (HBA1, HBA2, HBB). Overall, these data support a role of miR-16 in normal erythropoiesis. In case of PV we employed a knock-down strategy using either pre-miR-16-1 or pre-miR-16-2 siRNAs. The use of miR-16-2 siRNA resulted in significant reduction of Epo-independent erythroid colonies (EEC) from GFP-sorted CD34+ cells (60±18% lower than scramble) while no change was observed in cell treated with anti-miR-16-1. These data were confirmed in independent experiments using peripheral blood mononuclear cells (MNC): the number of EEC decreased from 207±20 to 170±23 to 95±25/105 MNC in cells transduced with scramble, anti miR-16-1 or miR-16-2, respectively (P<.01 for miR-16-2 vs others). Also the number of BFU-E generated in cytokine-supplemented cultures of PV MNC was significantly reduced by miR-16-2 siRNA (360±80) compared to cells transduced with scramble (540±120) or miR-16-1 (500±87) (P<.001). In summary, these data support a role for deregulated miR-16-2 in abnormal erythropoiesis of PV, and anticipate its possible relevance as a therapeutic target.

Full textAbstract:
Abstract Background Protease inhibitors are defense proteins widely distributed in the plant kingdom. By reducing the activity of digestive enzymes in insect guts, they reduce the availability of nutrients and thus impair the growth and development of the attacking herbivore. One well-characterized class of protease inhibitors are Kunitz-type trypsin inhibitors (KTIs), which have been described in various plant species, including Populus spp. Long-lived woody perennials like poplar trees encounter a huge diversity of herbivores, but the specificity of tree defenses towards different herbivore species is hardly studied. We therefore aimed to investigate the induction of KTIs in black poplar (P. nigra) leaves upon herbivory by three different chewing herbivores, Lymantria dispar and Amata mogadorensis caterpillars, and Phratora vulgatissima beetles. Results We identified and generated full-length cDNA sequences of 17 KTIs that are upregulated upon herbivory in black poplar leaves, and analyzed the expression patterns of the eight most up-regulated KTIs via qRT-PCR. We found that beetles elicited higher transcriptional induction of KTIs than caterpillars, and that both caterpillar species induced similar KTI expression levels. Furthermore, KTI expression strongly correlated with the trypsin-inhibiting activity in the herbivore-damaged leaves, but was not dependent on damage severity, i.e. leaf area loss, for most of the genes. Conclusions We conclude that the induction of KTIs in black poplar is controlled at the transcriptional level in a threshold-based manner and is strongly influenced by the species identity of the herbivore. However, the underlying molecular mechanisms and ecological consequences of these patterns remain to be investigated.

Full textAbstract:
This study presents an investigation of Amiata donkey health and quality of milk for human consumption. Thirty-one lactating dairy jennies were examined. The following samples were collected: faecal samples from the rectum of animals for parasitological examination; cervical swabs for the detection of bacteria causing reproductive disorders; and blood samples for serological diagnosis of main zoonotic (<em>Brucella</em> spp., <em>Leptospira</em> spp.) and donkey abortion agents (<em>Brucella</em> spp., <em>Leptospira</em> spp., <em>Salmonella abortus equi</em>, Equine viral arterithis virus, Equine herpesvirus type 1). In addition, individual milk samples were collected and analysed for mastitis- causing pathogens and milk quality. Regarding animal health, we detected a high prevalence of strongyle parasites in donkeys. It is very important to tackle parasitic diseases correctly. Selective control programmes are preferable in order to reduce anthelmintic drug use. For dairy donkeys, withdrawal periods from anthelmintic drugs need to be carefully managed, in accordance with EU and national regulations. The isolation of <em>Staphylococcus aureus</em> in milk highlights the importance of preventing contamination during milking, by adopting appropriate hygiene and safety practices at a farm level. Lysozyme activity was high compared to cow’s milk, contributing to the inhibitory activity against certain bacteria. Donkey milk was characterised by high lactose content, low caseins, low fat, higher levels of unsaturated fatty acids compared to ruminant milks. Unsaturated fatty acids and omega 3 fatty acids in particular have become known for their beneficial health effect, which is favourable for human diet. These characteristics make it suitable for infants and children affected by food intolerance/ allergies to bovine milk proteins and multiple food allergies as well as for adults with dyslipidemias. It is also recommended to prevent cardiovascular diseases.

Full textAbstract:
Abstract Pieris rapae and Phyllotreta nemorum are Brassicaceae specialists, but do not feed on Iberis amara spp. that contain cucurbitacins. The cucurbitacins are highly oxygenated triterpenoid, occurring widespread in cucurbitaceous species and in a few other plant families. Using de-novo assembled transcriptomics from I. amara, gene co-expression analysis and comparative genomics, we unraveled the evolutionary origin of the insect deterrent cucurbitacins in I. amara. Phylogenetic analysis of five oxidosqualene cyclases and heterologous expression allowed us to identify the first committed enzyme in cucurbitacin biosynthesis in I. amara, cucurbitadienol synthase (IaCPQ). In addition, two species-specific cytochrome P450s (CYP708A16 and CYP708A15) were identified that catalyse the unique C16 and C22 hydroxylation of the cucurbitadienol backbone, enzymatic steps that have not been reported before. Furthermore, the draft genome assembly of I. amara showed that the IaCPQ was localized to the same scaffold together with CYP708A15 but spanning over 100 kb, this contrasts with the highly organized cucurbitacin gene cluster in the cucurbits. These results reveal that cucurbitacin biosynthesis has evolved convergently via different biosynthetic routes in different families rather than through divergence from an ancestral pathway. This study thus provides new insight into the mechanism of recurrent evolution and diversification of a plant defensive chemical.

Objective. To To evaluate potential effects of the aqueous extract of Quassia amara L. leaves on the cardiovascular and respiratory systems of adult male Sprague- Dawley rats.
Methods. The cardiovascular and respiratory effects of the Quassia amara L. leaf extract on adult male SpragueDawley rats were assessed using non-invasive blood pressure (NIBP) determination and head-out plethysmography, respectively, in a randomized, parallel group study. Mean observations of blood pressure and heart rate were recorded at different time periods after dosing. Respiratory flow and irritation effects were evaluated using mean observations of respiratory rate (RR), tidal volume (TV), mid-expiratory flow rate (EF50), time of inspiration (TI) and expiration (TE), and time of break (TB) and pause (TP).
Results. There were no significant differences among the control and the treatment groups in SBP, DBP and HR parameters. The extract showed statistically significant effect on mean RR by time period (F=2.45, p=0.0234), trends over time of TV among the dose groups (F=2.00, p=0.0202), and EF50 among dose groups ((F=3.11, p=0.0422). However, these did not correlate with the changes in the time of break (TB) and time of pause (TP) which are more sensitive and specific tests for respiratory irritation.
Conclusion. Aqueous leaf extract of Quassia appeared to have no significant effects on SBP, DPB, Pulse pressure, and HR. There are no conclusive dose-related respiratory flow or pulmonary irritation effects.

<p>Angka kecelakaan kerja di Indonesia masih sangat tinggi pada tahun 2018 dari data BPJS Ketenagaan kerjaan tercatat 157.313 kasus dan pekerjaan kontruksi termasuk penyumbang tertinggi kasus kecelakaan kerja. Berdasarkan data tersebut dilakukan penelitian kenapa hal itu dapat terjadi, faktor-faktor apa saja penyebab kecelakaan kerja dan bagaimana system perencanaan dan penanggulangan kecelakaan kerja pada proyek kontruksi. Penelitian ini menggunakan metode wawancara dan penyebaran kuisoner yang dibagikan kepada penanggung jawab keselamatan yaitu HSE. Instrumen penelitian yang digunakan mengacu pada Form HIRAC dengan 3 tahap pengisian HIRAC yaitu identifikasi bahaya, penilaian risiko dan pengengendalian bahaya. Berdasarkan analisis dan pembahasan pada proyek pembangunan Apartemen Tamansari Amarta dapat disimpulkan bahwa risiko yang paling tinggi yaitu pada pekerjaan <em>formwork slab</em> dan pekerjaan pemasangan kolom. Upaya pengendalian yang dilakukan yakni dengan menerapkan sistem hirarki kontrol. Dimulai dengan tahap eliminasi, dilanjutkan tahap administrasi berkaitan dengan standar operasional pelaksanaan (SOP), dan yang terakhir yaitu pemakaian alat pelindung diri (APD).</p>

Mengelompokkan objek kedalam gerombol-gerombol yang memiliki kemiripan adalah proses penggerombolan. Metode penggerombolan yang sering digunakan adalah metode berhirarki dan tak berhirarki, analisis gerombol hanya dapat digunakan jika datanya kontinu dan amatan yang relatif kecil. Penelitian ini membahas mengenai metode Two Step Cluster dengan peubah kontinu dan kategorik dalam mengelompokkan mahasiswa FMIPA Untan tahun 2018. Proses pengelompokkan metode Two Step Cluster dilakukan dengan dua tahapan. Tahap pertama gerombol awal membentuk CF Tree dengan pengukuran jarak Log-likelihood, sedangkan pada tahap pembentukan gerombol optimal dengan menghitung nilai BIC dan membandingkan rasio ukuran jarak antar gerombol. Peubah berpengaruh ditentukan dengan menggunakan uji Chi Square untuk peubah kategorik dan uji t-Student untuk peubah kontinu. Berdasarkan hasil penelitian dapat disimpulkan uji Two Step Cluster dengan menghitung nilai BIC menghasilkan dua belas gerombol maksimum dan perbandingan ukuran jarak terbesar menghasilkan tiga gerombol optimal. Gerombol satu memiliki karakteristik dengan jumlah mahasiswa berjenis kelamin perempuan lebih banyak dan seluruh mahasiswa berasal dari sekolah negeri. Gerombol kedua memiliki karakteristik mahasiswa lebih banyak berasal dari luar Kalimantan Barat dan pendidikan orang tua dari lulusan SD. Gerombol tiga dicirikan dengan karakteristik mahasiswa seluruhnya berasal dari sekolah swasta dan pendidikan orang tua berasal dari tingkat SMP. Oleh karena itu, banyak orang tua mahasiswa yang bekerja sebagai petani, pedagang dan swasta. Kata Kunci: analisis gerombol, peubah campuran, jarak log-likelihood
