Abstract:
The purpose of this 2-week, double-blinded, controlled clinical trial was to evaluate the efficacy of topical amino acid-complexed zinc gluconate formulated with boric acid (ZGB) or acetic acid (ZGA) versus a topical placebo in the treatment of yeast otitis externa in dogs. Included in the study were dogs with otitis externa and a cytopathological finding of yeast organisms in the affected ear. Ears were treated with the placebo, ZGA, or ZGB medications. Yeast counts as well as clinical appearance of the ears were monitored. Results revealed that ZGB significantly reduced the number of yeast organisms in cases of otitis externa.

Abstract:
In mice, transcription initiates at the mid-one-cell stage and transcriptional activity dramatically increases during the two-cell stage, a process called zygotic gene activation (ZGA). Associated with ZGA is a marked change in the pattern of gene expression that occurs after the second round of DNA replication. To distinguish ZGA before and after the second-round DNA replication, the former and latter are called minor and major ZGA, respectively. Although major ZGA are required for development beyond the two-cell stage, the function of minor ZGA is not well understood. Transiently inhibiting minor ZGA with 5, 6-dichloro-1-β-d-ribofuranosyl-benzimidazole (DRB) resulted in the majority of embryos arresting at the two-cell stage and retention of the H3K4me3 mark that normally decreases. After release from DRB, at which time major ZGA normally occurred, transcription initiated with characteristics of minor ZGA but not major ZGA, although degradation of maternal mRNA normally occurred. Thus, ZGA occurs sequentially starting with minor ZGA that is critical for the maternal-to-zygotic transition.

Abstract:
SummaryMinor and major zygotic genome activation (ZGA) are crucial for preimplantation development. During this process, histone variants and methylation influence chromatin accessibility and consequently regulated the expression of zygotic genes. However, the detailed exchanges of these modifications during ZGA remain to be determined. In the present study, the epigenetic modifications of histone 3 on lysine 9 (H3K9), 27 (H3K27) and 36 (H3K36), as well as four histone variants were determined during minor and major ZGA and in post-ZGA stages of mouse embryos. Firstly, microH2A1, H3K27me3 and H3K36me3 were asymmetrically stained in the female pronucleus during minor ZGA but lost staining in major ZGA. Secondly, H3K9me2 and H3K9me3 were strongly stained in the female pronucleus, but weakly stained in the male pronucleus and disappeared after ZGA. Thirdly, H2A.Z and H3.3 were symmetrically stained in male and female pronuclei during minor ZGA. Moreover, H3K27me2 was not statistically changed during mouse early development, while H3K36me2 was only detected in 2- and 4-cell embryos. In conclusion, our data revealed dynamics of histone methylation and variants during mice ZGA and provided details of their exchange in mice embryogenesis. Moreover, we further inferred that macroH2A1, H2A.Z, H3K9me2/3 and H3K27me2/3 may play crucial roles during mouse ZGA.

Abstract:
In mice, zygotic genome activation (ZGA) occurs in two steps: minor ZGA at the one–cell stage and major ZGA at the two–cell stage. Regarding the regulation of gene transcription, minor ZGA is known to have unique features, including a transcriptionally permissive state of chromatin and insufficient splicing processes. The molecular characteristics may originate from extremely open chromatin states in the one–cell stage zygotes, yet the precise underlying mechanism has not been well studied. Recently, the R-loop, a triple–stranded nucleic acid structure of the DNA/RNA hybrid, has been implicated in gene transcription and DNA replication. Therefore, in the present study, we examined the changes in R-loop dynamics during mouse zygotic development, and its roles in zygotic transcription or DNA replication. Our analysis revealed that R-loops persist in the genome of metaphase II oocytes and preimplantation embryos from the zygote to the blastocyst stage. In particular, zygotic R-loop levels dynamically change as development proceeds, showing that R-loop levels decrease as pronucleus maturation occurs. Mechanistically, R-loop dynamics are likely linked to ZGA, as inhibition of either DNA replication or transcription at the time of minor ZGA decreases R-loop levels in the pronuclei of zygotes. However, the induction of DNA damage by treatment with anticancer agents, including cisplatin or doxorubicin, does not elicit genome-wide changes in zygotic R-loop levels. Therefore, our study suggests that R-loop formation is mechanistically associated with the regulation of mouse ZGA, especially minor ZGA, by modulating gene transcription and DNA replication.

Abstract:
Endogenous retroviruses (ERVs), previously viewed as deleterious relics of ancestral retrovirus infections, are silenced in the vast majority of cells to minimize the risk of retrotransposition. Counterintuitively, bursts of ERV transcription usually occur during maternal-to-zygotic transition (MZT) in preimplantation embryos; this is regarded as a major landmark event in the zygotic genome activation (ZGA) process, indicating that ERVs play an active part in ZGA. Evolutionarily, the interaction between ERVs and hosts is mutually beneficial. The endogenization of retrovirus sequences rewires the gene regulatory network during ZGA, and ERV repression may lower germline fitness. Unfortunately, owing to various limitations of somatic cell nuclear transfer (SCNT) technology, both developmental arrest and ZGA abnormalities occur in a high percentage of cloned embryos, accompanied by ERV silencing, which may be caused by the activation failure of upstream ERV inducers. In this review, we discuss the functions and regulation of ERVs during the ZGA process and the feasibility of temporal control over ERVs in cloned embryos via exogenous double homeobox (DUX). We hypothesize that further accurate characterization of the ERV-rewired gene regulatory network during ZGA may provide a novel perspective on the development of preimplantation embryos.

Abstract:
Key transcription factors (TFs) play critical roles in zygotic genome activation (ZGA) during early embryogenesis, whereas genome-wide occupancies of only a few factors have been profiled during ZGA due to the limitation of cell numbers or the lack of high-quality antibodies. Here, we present FitCUT&RUN, a modified CUT&RUN method, in which an Fc fragment of immunoglobulin G is used for tagging, to profile TF occupancy in an antibody-free manner and demonstrate its reliability and robustness using as few as 5000 K562 cells. We applied FitCUT&RUN to zebrafish undergoing embryogenesis to generate reliable occupancy profiles of three known activators of zebrafish ZGA: Nanog, Pou5f3, and Sox19b. By profiling the time-series occupancy of Nanog during zebrafish ZGA, we observed a clear trend toward a gradual increase in Nanog occupancy and found that Nanog occupancy prior to the major phase of ZGA is important for the activation of some early transcribed genes.

Abstract:
Pre-implantation embryo development encompasses several key developmental events, especially the activation of zygotic genome activation (ZGA)-related genes. Endogenous retroviruses (ERVs), which are regarded as “deleterious genomic parasites”, were previously considered to be “junk DNA”. However, it is now known that ERVs, with limited conservatism across species, mediate conserved developmental processes (e.g., ZGA). Transcriptional activation of ERVs occurs during the transition from maternal control to zygotic genome control, signifying ZGA. ERVs are versatile participants in rewiring gene expression networks during epigenetic reprogramming. Particularly, a subtle balance exists between ERV activation and ERV repression in host–virus interplay, which leads to stage-specific ERV expression during pre-implantation embryo development. A large portion of somatic cell nuclear transfer (SCNT) embryos display developmental arrest and ZGA failure during pre-implantation embryo development. Furthermore, because of the close relationship between ERV activation and ZGA, exploring the regulatory mechanism underlying ERV activation may also shed more light on the enigma of SCNT embryo development in model animals.

Full text
Abstract:
Interchromatin granule clusters (IGCs) are universal nuclear domains. Their molecular composition and functions were studied in detail in somatic cells. Here, we studied IGCs in the nuclei of early mouse embryos during zygotic gene activation (ZGA). We found that the size of IGCs gradually increases during realization of ZGA events. Using immunocytochemical approaches, we showed that the molecular composition of IGCs is also modified in mouse embryos. The hyperphosphorylated form of RNA polymerase II and the transcription factor TFIID have been revealed in IGCs before the end of ZGA. Association of these factors with IGCs became more noticeable during ZGA realization. Our data suggest that IGCs in early mouse embryos have some functional peculiarities connected most probably with IGC formationde novo. We believe that IGCs in early mouse embryos not only are storage sites of splicing factors but also may be involved in mRNA metabolism and represent the multifunctional nuclear domains.

Abstract:
Zygotic genome activation (ZGA) plays an essential role in early embryonic development. Vitrification is a common assisted reproductive technology that frequently reduces the developmental competence of embryos. However, the effect of vitrification on porcine ZGA and gene expression during ZGA remains largely unclear. Here, we found that vitrification of pronuclear zygotes derived from parthenogenetic activation (PA) and in vitro fertilization (IVF) resulted in a significant reduction in the rates of 2-cell, 4-cell, and blastocysts, but did not affect the quality of blastocysts. Functional research revealed that RNA polymerase II Inhibitor (α-amanitin) treatment significantly reduced global transcriptional activity and developmental efficiency of both 4-cell and 8-cell embryos, implying an essential role of ZGA in porcine early embryonic development. Furthermore, vitrification did not affect the synthesis of nascent mRNA of 2-cell embryos, but significantly inhibited global transcriptional activity of both 4-cell and 8-cell embryos, suggesting an impaired effect of vitrification on porcine ZGA. Correspondingly, the single-cell analysis showed that vitrification caused the downregulation or upregulation expression of maternal genes in 4-cell embryos, also significantly decreased the expression of zygotic genes. Taken together, these results indicated that vitrification of pronuclear zygotes impairs porcine zygotic genome activation.

Abstract:
This paper focuses on the zeolite-granule-adsorbent(ZGA)’s efficiency of removing ammonium ion. The ZGA shows good performance with up to 73.41% for ammonium removal on the condition of ZGA loading 6g, contact time 6h, initial ammonium concentration 50 mg/L and pH=6. The adsorption kinetics is best approximated by the pseudo-second-order model, whereas the adsorption isotherm results indicated that Langmuir model provides the best fit for the equilibrium data. Furthermore, with regard to thermodynamic parameters, it was found that Gibbs free energy change (ΔG°) −19.31kJ/mol at T=298K, The negative data indicates the spontaneous nature of the adsorption process.

Abstract:
Embryonic stem cells (ESCs) are characterized by a rapid cell cycle, which leads to high replication stress (RS) in otherwise unperturbed conditions. The mechanisms that ESCs adopt to cope with their endogenous RS, however, remain to this day elusive. In our recent work we demonstrated that the activation of the checkpoint kinase ATR in response to RS leads to a broad activation of 2-cells stage specific genes in mouse ESCs. This response relies on the up-regulation of Dux, a transcription factor encoded in a macrosatellite sequence repeated in tandem. Dux is repressed by variant Polycomb repressive complex 1 (vPRC1) in unperturbed ESCs, independently from PRC2 presence. Here we demonstrate that RS causes a major rearrangement of both PRC1 and PRC2 in ESCs nuclei, resulting in a major loss of both repressive marks in correspondence to target promoters. Surprisingly, Dux undergoes an increase in vPRC1 occupancy upon RS in an ATR-dependent manner, possibly due to PRC1 involvement in the replication of highly repeated DNA sequences. More interestingly, Dux activation upon RS requires the presence of PRC2. This result is possibly due to PRC2 proved role in the processing of stalled replication forks, which are the main structure signaling RS. In agreement to this data, also the fork remodeling translocases HLTF and ZRANB3 displayed an effect in Dux activation following RS. Taken together, our results show that the up-regulation of 2-cells genes following RS not only requires ATR activation, but also downstream remodeling processes.

Narratives recollected from popular sources such as podcast and websites often inspire my animations, paintings, and drawings. My work serves as a pictorial manifestation of everything from visualized passages in literature to eavesdropping. I zigzag from one source to another, combining found images that are loosely associated with one another. I combine them in a simulated collage in order to form an interesting composition. My purpose is to create a magical moment that pulls us away from the monotony of life. Storytelling not only allows one to see oneself and how one relates to others, but it also can provide a way for a person to cope with the unpredictable nature of existence. I am hoping that my art will provide opportunities for the viewer to expand his/her own unique personal narrative.

In southern Brazil, Fusarium Head Blight (FHB) caused by the fungus Fusarium graminearum is severe disease because the fungus is abundant in winter and summer crop residues, which helps inoculation in susceptible maize hybrids when have excessive periods of rain after pollination phase. This research aimed to determine the best time to spray fungicide during maize silking to control FHB. The experiment was conducted in field at the experimental area of Agroveterinarias Sciences Center at the Santa Catarina State University (CAV/UDESC) in Lages, Santa Catarina. Were seeded simple hybrids P32R48 H and Maximus TL TG Viptera during two periods in the growing seasons of 2012/13 and 2013/14. After five days of stigma emergence, the ears were artificially inoculated with 1 x 105 macroconídios.mL-1 concentration of F. graminearum injecting 2 ml of inoculum solution in stigma-style channel. Inoculations happen in 03/08/2013, 03/22/2013, 12/26/2013 and 01/19/2014. The fungicide was a mixture of azoxystrobin + cyproconazole (300 mL c.p/ha) + carbendazim (1 L c.p/ha) + nimbus mineral oil (0.5% v.v/ha). The treats were six fungicide spray times: 144, 96 and 48 hours before inoculation; 48, 96 and 144 hours after inoculation and a control, only inoculated without fungicide application. The experiment design was randomized block with four replications. The fungicide was applied with a manual CO2 gas sprayer. The variables evaluated were severity of FHB in the ears (SGE), percentage of damaged kernels (PGA), incidence of F. graminearum in the grains (IFgG) and grain yield (RG). Data were subjected to variance analysis, Tukey´s test and simple correlation analysis. The hybrid P32R48H was more susceptible than Maximus TL TG Viptera to FHB. Sprays 48 hours before and after inoculation were effective to reduce SGE in approximately 50% and 41%; to reduce PGA by 33% and 50%; to reduce IFgG by 27%; and to increase RG by 9% and 7%, respectively when compared to control. There is a negative linear correlation between SGE, PGA, IFgG and RG variables. The yield and grain quality were improved by fungicide spray between the 3rd and 7th day period after stigma issue
Na região Sul do Brasil, a podridão de espiga de giberela, causada pelo fungo Fusarium graminearum, é uma doença preocupante, pois o fungo é abundante nos resíduos culturais das gramíneas de inverno e de verão, o que facilita a sua inoculação nas espigas de híbridos suscetíveis em safras com excesso de chuva após a fase da polinização. Este trabalho de pesquisa teve como objetivo definir o melhor momento para pulverização de fungicida durante o estádio do espigamento do milho para controlar a podridão de espiga de giberela. O experimento foi conduzido à campo, na área experimental do Centro de Ciências Agroveterinárias da Universidade do Estado de Santa Catarina (CAV/UDESC) no município de Lages, Santa Catarina. Foram semeados os híbridos simples P32R48 H e Maximus TL TG Viptera, em duas épocas nas safras agrícolas de 2012/13 e 2013/14. Após cinco dias da emissão dos estigmas, as espigas foram inoculadas artificialmente com uma concentração de 1 x 105 macroconídios.mL-1 de F. graminearum injetando 2 mL da solução de inóculo no canal do estilo-estigma. As inoculações foram realizadas nos dias 08/03/2013, 22/03/2013, 26/12/2013 e 19/01/2014. O fungicida utilizado foi a mistura de azoxistrobina + ciproconazole (300 mL p.c/ha) + carbendazim (1 L p.c/ha) + oléo mineral Nimbus (0,5% v.v./ha). Os tratamentos constituiram-se em seis momentos de pulverização do fungicida: 144, 96 e 48 horas antes da inoculação; 48, 96 e 144 horas depois da inoculação e uma testemunha, somente inoculado sem aplicação de fungicida. A distribuição dos tratamentos seguiu o modelo do delineamento em blocos casualizados, com quatro repetições. O fungicida foi aplicado com o auxílio de pulverizador costal com pressão produzida por gás CO2. As variáveis avaliadas foram severidade da giberela nas espigas (SGE), porcentagem de grãos ardidos (PGA), incidência de F. graminearum nos grãos (IFgG) e rendimento de grãos (RG). Os dados obtidos foram submetidos à análise de variância, ao teste de Tukey e a análise de correlação simples. O híbrido P32R48H apresentou-se mais suscetível a podridão de giberela. As pulverizações 48 horas antes e depois da inoculação foram eficientes em reduzir a SGE em aproximadamente 50% e 41%; em reduzir a PGA em 33% e 50%; em reduzir a IFgG em 27%; e em aumentar o RG em 9% e 7%, respectivamente quando comparados ao tratamento sem fungicida. Existe associação entre as variáveis SGE, PGA, IFgG e RG. Pode-se aumentar o rendimento e melhorar a qualidade de grãos com a aplicação de fungicida no período do 3º ao 7º dia após a emissão dos estigmas

Abstract:
The glutathione transferases (GSTs) of maize have been the most studied GSTs in plants, however much is still not known about these enzymes. In the course of the current study six GST subunits (Zm GSTs I, II and III, which have been reported previously, and Zm GSTs V, VI and VII, which have not been previously reported) have been identified in the dimers Zm GST I-I, I-II, I-III, V-V, V-VI and V-VII. Maize GSTs are known to be important in herbicide detoxification and the purified maize enzymes were each found to have differing activities toward a number of herbicides, and also a range of other potential GST substrates. Additionally, Zm GST I II and Zm GST V-V possessed glutathione peroxidase activity. The developmental regulation and chemical inducibility of maize GSTs were studied in maize seedlings using western blotting, with different subunits showing markedly different responses. Zm GST I was constitutively present in all plant parts and unaffected by chemical treatment, Zm GST II was only detected in young roots but was induced in roots and shoots by many different chemical treatments, and Zm GST V was present at low levels throughout maize plants, with levels enhanced greatly by treatment with the safener dichlormid but not by other chemicals tested. cDNA clones corresponding to Zm GST subunits I, III, V, VI and VII were isolated by library screening using antibody or DNA probes. The cDNA sequences for Zm GST subunits V, VI and VH were different from those of previously cloned type I (theta class) maize GSTs and were most similar to the auxin-regulated GST family (type III or tau class GSTs) previously only identified in dicotyledonous species. The cloned GSTs were expressed as recombinant proteins in E. coli, allowing further characterisation, including detailed kinetic analysis for recombinant Zm GST I-I and Zm GST V-V.

Abstract:
Evropska unija je opredelila ključna področja, na katerih zaostaja za glavnimi svetovnimi konkurenti, ZDA, Ja-ponsko in hitro rastočimi azijskimi gospodarstvi. Ta področja so sprejetje IKT v poslovanje, dostop do investicijskih skladov in inovacijske politike. Ena izmed ključnih konkurenčnih panog v Evropi je turizem, ki ima skupne probleme z drugimi panogami. Evropski turizem temelji predvsem na malih in srednje velikih podjetjih, ki imajo razdrobljen in razpršen potencial rasti, nizko sposobnost pridobivanja in uporabe znanja ter imajo omejen dostop do rizičnega kapitala. Evropska strategija pametne specializacije naslavlja te probleme v okviru panoge turizem z oblikovanjem tematske platforme „Digitalizacija in varnost v turizmu“. Njeno poslanstvo je ustvariti skupne in participativne storitve za povečanje medregionalnih naložb v digitalizacijo v turističnem sektorju. Namen platforme je služiti kot osnova za razvoj prihodnjega digitalnega evropskega turizma. V prispevku opisujemo platformo in njeno navezavo na Turizem 4.0 v Sloveniji.

Abstract:
Uvod: Domovi za starije i nemoćne osobe pružaju skrb starijim i nemoćnim osobama izvan vlastite obitelji, a u sklopu stalnog smještaja osiguravaju cjelovitu skrb. Tjelesna aktivnost ima zadatak održati ili poboljšati funkcijske sposobnosti do kojih neminovno dolazi starenjem i učestalijom pojavom bolesti, također prevenira, liječi i rehabilitira određene akutne i kronične bolesti. Materijali i metode: Cilj rada bio je prikazati stanje zdravlja starijih osoba s obzirom na osnovne varijable poput dobi, spola, rizičnog ponašanja, vrste oboljenja, s posebnim osvrtom na tjelesnu aktivnost. Istraživanje je provedeno u ustanovama domova za starije i nemoćne na području Federacije Bosne i Hercegovine na području Srednjobosanske, Sarajevske, Hercegovačko-neretvanske i Zapadnohercegovačke županije. Rezultati: Istraživanjem je utvrđeno kako je veći broj osoba ženskoga spola (60%) smješten u domovima za starije i nemoćne uz najčešću životnu dob od 75 do 79 godina života (21%). Najčešće kronične bolesti koje su zastupljene kod ovih osoba su hipertenzija (22%), dijabetes (21%) i osteoporoza (4%). Neznatno je veći udio ispitanika koji se bave tjelesnim vježbanjem (51%), a najveći broj ispitanika ne zna koje su prednosti bavljenja tjelesnim aktivnostima (55%). Zaključak: Možemo zaključiti kako svaka aktivnost, prilagođena pojedinom štićeniku, može osobu učiniti pokretljivijom i u konačnici zdravijom i manje ovisnom o pomoći drugih.

Abstract:
Zwa (P1A1) is a platelet specific alloantigen, located on glycoprotein (GP) IIIa, and is of pathogenic importance in alloimmunologic disorders such as neonatal alloimmune thrombocytopenia and post transfusion purpura. As endothelial cells synthesize a plasma membrane protein complex which is structurally closely related to the platelet membrane GP IIb/IIIa complex, we examined whether these cells also express Zwa. Employing a variety of immunochemical techniques, our studies show that endothelial cells indeed can express this antigen at the plasma membrane surface.We also compared the expression of Zwa on platelets, isolated from umbilical cord blood, with the expression of Zwa on cultured endothelial cells, isolated from the same umbilical cord, of a number of neonates. Both platelets and endothelial cells obtained from the same individual, either expressed Zwa (Zwa positive individuals) or lacked expression of Zwa (Zwa negative individuals). These findings strongly suggest that endothelial-and platelet Zwa are encoded by the same genes.Thus, Zwa is not exclusively expressed by platelets, also endothelial cells express this alloantigen.An important consequence could be, that in alloimmunologic disorders in which the Zwa antigen is implicated, not only the platelets, but also the vessel wall is involved.

Abstract:
Phytophagous insects respond to chemicals from their host plants in a number of ways, including orientation or attraction in response to volatiles produced by plants. Orientation to odors from host plants may occur in order to locate food, mates, or oviposition sites. A detailed understanding of these behaviors are the chemical stimuli evoking them may provide useful means for attracting and trapping insect pests of crop plants. Heliothine moths (Helicoverpa and Heliothis herein) include a number of major pests of cultivated crop plants throughout the world. In North America, these include Heliothis virescens and Helicoverpa zea. In much of Eurasia (including Israel) Australia, and Africa, these include Helicoverpa armigera and Helicoverpa peltigera. These 4 species of concern all are attracted to odorants from host plants (Tingle and Mitchell 2992, Mitchell et al 1991, 1992 BARD feasibility study report). Host plant chemicals also play a role in the sexual behavior of Helicoverpa species. Synthesis and possibly release of sex pheromone in H. zea and H. phloxiphaga is stimulated by kairomones from hosts plants (Raina 1988, 1992). Pheromona scent marking on host plants also occurs in H. virescens and H. zea. Studies of several other insects, including the cabbage looper Trichoplusia ni, have a variety of other behaviors may occur in association with host plants, including the use of plants as sexual rendesvous sites and of direct involvement of plant chemicals in sexual behavior. Some pest species of moths also may use host plants as adult food sources. These studies were undertaken to develop a more thorough understanding of how Heliothis/Helicoverpa moths use host plant odorants to locate and select foods, mates, and oviposition sites. We used Heliothis virescens and Helicoverpa zea in Florida, and Helicoverpa armigera and Helicoverpa peltigera in Israel as objects of study because of their pest status. It is hoped that such an understanding will provide direction for work to discover and develop novel means to control these pests through behavioral manipulation. The specific objectives of the proposal were to 1) identify host odor affects on known Heliothine sexual behavior, 2) identify novel sexual behavior that is how dependent, 3) isolate and characterize host kairomones important to pest Heliothine host and mate-location behavior, and 4) investigate female attraction to males.
