Abstract:

The filamentous fungus Aspergillus niger is an industrially exploited protein expression platform, well known for its capacity to secrete high levels of proteins. To study the process of protein secretion in A. niger, we established a GFP-v-SNARE reporter strain in which the trafficking and dynamics of secretory vesicles can be followed in vivo. The biological role of putative A. niger orthologues of seven secretion-specific genes, known to function in key aspects of the protein secretion machinery in Saccharomyces cerevisiae, was analysed by constructing respective gene deletion mutants in the GFP-v-SNARE reporter strain. Comparison of the deletion phenotype of conserved proteins functioning in the secretory pathway revealed common features but also interesting differences between S. cerevisiae and A. niger. Deletion of the S. cerevisiae Sec2p orthologue in A. niger (SecB), encoding a guanine exchange factor for the GTPase Sec4p (SrgA in A. niger), did not have an obvious phenotype, while SEC2 deletion in S. cerevisiae is lethal. Similarly, deletion of the A. niger orthologue of the S. cerevisiae exocyst subunit Sec3p (SecC) did not result in a lethal phenotype as in S. cerevisiae, although severe growth reduction of A. niger was observed. Deletion of secA, secH and ssoA (encoding SecA, SecH and SsoA the A. niger orthologues of S. cerevisiae Sec1p, Sec8p and Sso1/2p, respectively) showed that these genes are essential for A. niger, similar to the situation in S. cerevisiae. These data demonstrate that the orchestration of exocyst-mediated vesicle transport is only partially conserved in S. cerevisiae and A. niger.

Abstract:

This study assessed the differences between immigrants and natives in terms of combined effects of sugar-sweetened beverage (SSB) or snack consumption and preventive behaviors for severe early childhood caries (SECC) through a large-scale survey of 31,565 native and 1046 immigrant child–parent pairs in Taiwan. Children aged 3–5 years underwent dental examinations, and parents completed structured questionnaires. Immigrants had a significantly higher SECC prevalence than native children (32.3% vs. 19.4%). A combined effect of SECC was observed in native children who did not receive assistance when brushing teeth at night before sleep and those who consumed SSBs more than four times weekly (adjusted odds ratio (aOR) = 4.8). Moreover, native children who did not use dental floss and who consumed snacks more than four times weekly had an aOR of 4.1 for SECC. The combined effects of children with immigrant parents who did not receive assistance when brushing their teeth at night before sleep and those who consumed snacks more than four times weekly had an aOR of 8.2 for SECC. The results suggest the necessity of cross-cultural caries prevention programs for immigrants. Parents must limit children’s SSB and snack intake, and implement preventive measures to reduce SECC development.

Abstract:

ABSTRACT The Gram-positive pathogen Staphylococcus aureus secretes various proteins into its extracellular milieu. Bioinformatics analyses have indicated that most of these proteins are directed to the canonical Sec pathway, which consists of the translocation motor SecA and a membrane-embedded channel composed of the SecY, SecE, and SecG proteins. In addition, S. aureus contains an accessory Sec2 pathway involving the SecA2 and SecY2 proteins. Here, we have addressed the roles of the nonessential channel components SecG and SecY2 in the biogenesis of the extracellular proteome of S. aureus. The results show that SecG is of major importance for protein secretion by S. aureus. Specifically, the extracellular accumulation of nine abundant exoproteins and seven cell wall-bound proteins was significantly affected in an secG mutant. No secretion defects were detected for strains with a secY2 single mutation. However, deletion of secY2 exacerbated the secretion defects of secG mutants, affecting the extracellular accumulation of one additional exoprotein and one cell wall protein. Furthermore, an secG secY2 double mutant displayed a synthetic growth defect. This might relate to a slightly elevated expression of sraP, encoding the only known substrate for the Sec2 pathway, in cells lacking SecG. Additionally, the results suggest that SecY2 can interact with the Sec1 channel, which would be consistent with the presence of a single set of secE and secG genes in S. aureus.

Abstract:

ABSTRACT The majority of secretory proteins are translocated into and across hydrophobic membranes via the universally conserved Sec pore. Accessory proteins, including the SecDF-YajC Escherichia coli membrane complex, are required for efficient protein secretion. E. coli SecDF-YajC has been proposed to be involved in the membrane cycling of SecA, the cytoplasmic bacterial translocation ATPase, and in the stabilizing of SecG, a subunit of the Sec pore. While there are no identified archaeal homologs of either SecA or SecG, many archaea possess homologs of SecD and SecF. Here, we present the first study that addresses the function of archaeal SecD and SecF homologs. We show that the SecD and SecF components in the model archaeon Haloferax volcanii form a cytoplasmic membrane complex in the native host. Furthermore, as in E. coli, an H. volcanii ΔsecFD mutant strain exhibits both severe cold sensitivity and a Sec-specific protein translocation defect. Taken together, these results demonstrate significant functional conservation among the prokaryotic SecD and SecF homologs despite the distinct composition of their translocation machineries.

Abstract:

This study carried out tensile tests at definite elongation, tensile and shear tests on 4 admixture-modified styrene-acrylic emulsion-based cement composites (SECCs), and measured the strength, deformation, and energy consumption indexes of test specimens, so as to investigate the influences of coalescing agent, plasticizer, silane coupling agent, and nanometer aluminium oxide on the bond, tensile, and shear mechanical properties of the test specimens. Additionally, the Field Emission Scanning Electron Microscope (FE-SEM) test and Mercury Intrusion Porosimetry (MIP) test were conducted on the composite material specimens, to analyze the microscopic mechanism of different admixtures in modifying the mechanical properties of the SECC. The results suggested that the addition of coalescing agent, plasticizer, silane coupling agent, and nanometer aluminium oxide improved the bond, tensile and shear properties of the SECC specimens to various degrees. Of them, the coalescing agent promoted the mutual cross-linking of organic polymers with inorganic products, and optimized the transition interface to enhance the comprehensive mechanical properties of the test specimens; by contrast, nanometer aluminium oxide developed secondary hydration reaction with the inorganic products, and refined the pore structure to modify the mechanical properties of test specimens. Therefore, both of them achieved significant modification effects. Typically, the optimal bond properties of FFAMC, PLMC, SCAMC, and NAMC test specimens were achieved at the coalescing agent, plasticizer, silane coupling agent, and nanometer aluminium oxide addition amounts of 4%, 1.5%, 3%, and 1%, respectively. Besides, the improving effects of different admixtures on the tensile property of SECC specimens followed the order of coalescing agent > nanometer aluminium oxide > plasticizer > silane coupling agent, with the optimal addition amounts of 4%, 1.5%, 1%, and 2%, respectively. In addition, the improving effects of different admixtures on the shear performance of SECC specimens followed the order of coalescing agent > nanometer aluminium oxide > silane coupling agent > plasticizer, with the optimal addition amounts of 4%, 1.5%, 1%, and 1%, respectively.

Abstract:

Two new temperature-sensitive alleles of SEC3, 1 of 10 late-acting SEC genes required for targeting or fusion of post-Golgi secretory vesicles to the plasma membrane in Saccharomyces cerevisiae, were isolated in a screen for temperature-sensitive secretory mutants that are synthetically lethal with sec4-8. The new sec3 alleles affect early as well as late stages of secretion. Cloning and sequencing of the SEC3 gene revealed that it is identical to profilin synthetic lethal 1 (PSL1). The SEC3 gene is not essential because cells depleted of Sec3p are viable although slow growing and temperature sensitive. All of the sec3 alleles genetically interact with a profilin mutation, pfy1-111. The SEC3 gene in high copy suppresses pfy1-111 and sec5-24 and causes synthetic growth defects with ypt1, sec8-9, sec10-2, and sec15-1. Actin structure is only perturbed in conditions of chronic loss of Sec3p function, implying that Sec3p does not directly regulate actin. All alleles of sec3 cause bud site selection defects in homozygous diploids, as do sec4-8 and sec9-4. This suggests that SEC gene products are involved in determining the bud site and is consistent with a role for Sec3p in determining the correct site of exocytosis.

Abstract:

Early childhood caries (ECC) is recognized as an infectious disease. The first step in its development is primary infection by the bacterium S. mutans which has been identified as the primary etiologic factors in dental caries. Lactobacilli were also found to play a role in the progression of the disease. However, the underlying mechanism of immune response to caries is still unclear. The purpose of this study was to assess the level of cariogenic bacteria namely S. mutans and lactobacilli in caries free children, and children with SECC and their corresponding mothers. The study also aims at correlating the children's levels to their mothers. Sixty children and their mothers attending the dental clinic in King Abdulaziz University participated in our study. Their age ranged from 3 – 5 years. The study groups consisted of 30 children with SECC and a control group comprising of 30 caries free children. Children together with their mothers were examined and their caries level was recorded. Stimulated saliva was collected from each participant for bacterial, immunological assessment, and Lactobacilli counts in each sample were determined. Children with SECC had higher levels of S. mutans and Lactobacilli than caries free children. The mothers of children with SECC had a statistically higher count of Lactobacilli than caries free children's mothers. However, the difference was not statistically significant with respect to their S. mutans counts. A significant relationship exists among the mother- child pair in the SECC group with respect to S. mutans level in saliva.

Abstract:

Aim:Intraoperative allogeneic blood product transfusion (ABPT) in cardiac surgery is associated with worse overall outcome, including mortality. The objective of this study was to evaluate the ABPTs in minimalized extracorporeal cardiopulmonary (MECCTM) compared with standard open system on-pump coronary revascularization.Methods:Data of 156 patients undergoing myocardial revascularization between September 2008 and September 2010 were reviewed. 83 patients were operated by the MECC technique and 73 were treated by standard extracorporeal circulation (sECC). ABPT and overall early postoperative complications were analyzed.Results:Operative mortality and morbidity were similar in both groups. ABPT in the MECC group was significantly lower than in the sECC group both intraoperatively (7.2vs.60.3% of patients p<0.001) and during the first five postoperative days (19.3vs.57.5%; p<0.001). “Skin to skin”- (214 ± 45vs.232 ± 45 min; p=0.012), cardiopulmonary bypass (CPB) - (82 ± 25vs.95 ± 26 min; p=0.014), and X-clamp- times (50 ± 16vs.56 ± 17 min; p=0.024) were significantly lower in the MECC group than in the sECC group. Length of ICU (intensive care unit) - and hospital stay were also significantly lower in the MECC groupvs.the sECC group (26.7 ± 20.2vs.54.5 ± 68.9 h; p<0.001, and 12.0 ± 4.1vs.14.5 ± 4.6 days; p<0.001).Conclusion:Application of MECC as on-pump coronary artery bypass graft (CABG) results in significantly lower ABPT as well as shorter ICU and in-hospital stay. In order to achieve these benefits of MECC autologous retrograde priming, Bispectral index (BIS) monitoring, intraoperative cell salvage, meticulous hemostasis and strict peri- and postoperative volume management are crucial.

Abstract:

AbstractThe surface circulation of the tropical Pacific Ocean is characterized by alternating zonal currents, such as the North Equatorial Current (NEC), North Equatorial Countercurrent (NECC), South Equatorial Current (SEC), and South Equatorial Countercurrent (SECC). In situ measurements of subsurface moorings and satellite observations reveal pronounced intraseasonal variability (ISV; 20–90 days) of these zonal currents in the western tropical Pacific Ocean (WTPO). The amplitude of ISV is the largest within the equatorial band exceeding 20 cm s−1 and decreases to ~10 cm s−1 in the NECC band and further to 4–8 cm s−1 in the NEC and SECC. The ISV power generally increases from high frequencies to low frequencies and exhibits a peak at 50–60 days in the NECC, SEC, and SECC. These variations are faithfully reproduced by an ocean general circulation model (OGCM) forced by satellite winds, and parallel model experiments are performed to gain insights into the underlying mechanisms. It is found that large-scale ISV (>500 km) is primarily caused by atmospheric intraseasonal oscillations (ISOs), such as the Madden–Julian oscillation (MJO), through wind stress forcing. These signals are confined within 10°S–8°N, mainly as baroclinic ocean wave responses to ISO winds. For scales shorter than 200 km, ISV is dominated by ocean internal variabilities with mesoscale structures. They arise from the baroclinic and barotropic instabilities associated with the vertical and horizontal shears of the upper-ocean circulation. The ISV exhibits evident seasonal variation, with larger (smaller) amplitude in boreal winter (summer) in the SEC and SECC.

Abstract:

The Indian Ocean is influenced by monsoon systems which alter the ocean’s physical and chemical properties. Specifically, the southwestern Sumatran waters in the eastern Indian Ocean are considered a dual current regulated zone i.e. affected by South Equatorial Counter Current (SECC) and South Java Current (SJC). This area is considered as having an important role in the transfer of organic matter or the biological pump. However, the information about this area is minimal, especially in terms of organic matter and nutrient profile. This study will update the recent information about the area, including the profile of particulate organic matter (POM), macro-nutrients, total suspended solids (TSS), macromolecule-degradingbacteria, and soft bottom macrobenthic organisms sampled from 26 stations in both the SECC-regulated zone and the SJC-regulated zone. The physical profile is typical of tropical watersand both zones have a distinct profile of organic matter and nutrients. The particulate organic carbon (POC), particulate organic nitrogen (PON), and TSS of the SECC-regulated zone can be considered higher than those of the SJC-regulated zone. This region is categorized as mesotrophic waters, especially from the surface up to 100 m. The production of nutrients and organic matter in the water column in this area contribute significantly to the abundance of heterotrophic bacteria and benthic organisms.

Abstract:

Trafficking of protein and lipid cargo through the secretory pathway in eukaryotic cells is mediated by membrane-bound vesicles. Secretory vesicle targeting and fusion require a conserved multisubunit protein complex termed the exocyst, which has been implicated in specific tethering of vesicles to sites of polarized exocytosis. The exocyst is directly involved in regulating soluble N-ethylmaleimide–sensitive factor (NSF) attachment protein receptor (SNARE) complexes and membrane fusion through interactions between the Sec6 subunit and the plasma membrane SNARE protein Sec9. Here we show another facet of Sec6 function—it directly binds Sec1, another SNARE regulator, but of the Sec1/Munc18 family. The Sec6–Sec1 interaction is exclusive of Sec6–Sec9 but compatible with Sec6–exocyst assembly. In contrast, the Sec6–exocyst interaction is incompatible with Sec6–Sec9. Therefore, upon vesicle arrival, Sec6 is proposed to release Sec9 in favor of Sec6–exocyst assembly and to simultaneously recruit Sec1 to sites of secretion for coordinated SNARE complex formation and membrane fusion.

Abstract:

In the yeast Saccharomyces cerevisiae, the products of at least 14 genes are involved specifically in vesicular transport from the Golgi apparatus to the plasma membrane. Two of these genes, SEC8 and SEC15, encode components of a 1-2-million D multi-subunit complex that is found in the cytoplasm and associated with the plasma membrane. In this study, oligonucleotide-directed mutagenesis is used to alter the COOH-terminal portion of Sec8 with a 6-histidine tag, a 9E10 c-myc epitope, or both, to allow the isolation of the Sec8/15 complex from yeast lysates either by immobilized metal affinity chromatography or by immunoprecipitation. Sec6 cofractionates with Sec8/15 by immobilized metal affinity chromatography, gel filtration chromatography, and by sucrose velocity centrifugation. Sec6 and Sec15 coimmunoprecipitate from lysates with c-myc-tagged Sec8. These data indicate that the Sec8/15 complex contains Sec6 as a stable component. Additional proteins associated with Sec6/8/15 were identified by immunoprecipitations from radiolabeled lysates. The entire Sec6/8/15 complex contains at least eight polypeptides which range in molecular mass from 70 to 144 kD. Yeast strains containing temperature sensitive mutations in the SEC genes were also transformed with the SEC8-c-myc-6-histidine construct and analyzed by immunoprecipitation. The composition of the Sec6/8/15 complex is disrupted specifically in the sec3-2, sec5-24, and sec10-2 strain backgrounds. The c-myc-Sec8 protein is localized by immunofluorescence to small bud tips indicating that the Sec6/8/15 complex may function at sites of exocytosis.

Abstract:

Background/Objective: To retrospectively analyze the characteristics, tendencies, and success rates of dental treatments for severe early childhood caries (SECC) under general anesthesia (GA) in in northwest China. Study design: Children diagnosed with SECC were included in this retrospective study. From January 2015 to December 2018, they received dental treatment under GA at Affiliated Stomatology Hospital of Xi’an Jiaotong University. Demographic information, caries status and treatment characteristics were collected from electronic medical record system. Success rates of different treatments at 6-month and 12-month follow up were also analyzed. Results: A total of 846 children (477 male, 369 female) received dental treatment under GA. The case number was increased from 148 in 2015 to 278 in 2018. There were 81.2% and 70.8% of the children participated the 6-month and 12-month follow up. SSC and pulpotomy was the most successful restorations and pulp therapy, with the success rate of 97.09% and 93.98% in 12-month follow up, respectively. The use of crown restorations (including composite resin crown and stainless steel crown) and pulp reservation therapies (including indirect pulp therapy and pulpotomy) were significantly increased while composite resin filling and pulpectomy decreased during 2015 to 2018. Conclusion: There has been an increasing demand for dental treatment under GA for children with SECC in northwest China, with a trend toward younger ages. With better clinical outcomes, crown restorations and pulp reservation therapies were the fastest-growing treatments under GA.

Abstract:

Abstract Two decades of drifter and satellite data allow the authors to describe the seasonal evolution of the surface circulation of the Arabian Sea, which reverses annually with the Indian monsoon winds. This study finds several features that advance current understanding. Most significantly, northward flow appears along the length of the western boundary, together with a weak anticyclone at 6°N (a precursor to the Great Whirl) as early as March or April, one or two months before the southwest monsoon winds. This circulation is driven by planetary waves, which are initiated by wind curl forcing during the previous southwest monsoon, leading the authors to speculate that there is an oceanic mechanism through which one monsoon may precondition the next. Second, the authors find that the eastward South Equatorial Counter Current (SECC) is present year-round, fed by the northward East African Coastal Current (EACC). During the southwest monsoon the EACC overshoots the equator and splits, feeding both northward into the Somali Current and eastward into the SECC by looping back across the equator. This retroflection of the EACC is what was previously known as the southern gyre. At the surface, this circulation is obscured by strong, locally wind-driven, cross-equatorial transport. The semiannual variability of the SECC is governed by Ekman pumping over the equatorial gyre. Finally, there is broad, strong eastward flow at the mouth of the Gulf of Aden throughout the southwest monsoon, coincident with alongshore winds and a switch in sign of the wind stress curl along the axis of the atmospheric monsoon jet.

Abstract:

<em>This paper analyzes latest findings from the recently completed Socio Economic and Caste Census 2011(SECC2011), by focusing on rural abject poverty and multi-dimensionality of it by the pre-set seven deprivation parameters across rural India .As per schema of SECC2011 for analyzing the various facets of multi-dimensional poverty, firstly one set of households will be excluded on the basis of 13 automatic exclusion parameters, and subsequently another set of households will be automatically included on the basis of five parameters and finally the remaining set would be subjected to verifications by seven deprivations. Thereby, the SECC 2011 had set in motion an effort to capture some specifics of multidimensional poverty as desired by the Ministry of Rural Development (MoRD) in the Government of India. It is surmised here that the union of automatically included and deprived households will provide a base line of the number of poor through a multi-dimensional mode. The intersection of automatically included households with the seven deprivations variables will also identify the socio economic characteristics of the abjectly poor. Besides presenting the above analysis of SECC data, an attempt is made to compare these findings with those based on the unidimensional National Sample Survey (NSSO) poverty ratios ( by S.Tendulker 2009, C Rangarajan 2012) and multi-dimensional (R. Radhakrishna et al 2010) NFHS data based studies. A separate set of multi-dimensional poverty numbers were arrived at in the past for three Five Year Plans (1992-97, 1997- 02, 2002-07) through the Below Poverty Line (BPL) Censuses that were under taken by the Ministry of Rural Development (MoRD) to identify the poor households through the State/UT Governments. These later estimates of poor households were never permitted to exceed the official poverty ratio worked out by the Planning Commission for respective State/UT governments. The concepts used to arrive at these poor households will be briefly reviewed here as a prelude to explaining the modes operandi of identifying multi dimensional poverty via SECC 2011. A committee was set in up in February 2013 under the Chairmanship of Abhijit Sen , then Planning Commission Member, to examine the SECC indicators for data analysis, to recommend appropriate methodologies for determining classes of beneficiaries for different rural development programmes. Some of the recommendations of the committee would also be put to scrutiny. </em>

Abstract:

ABSTRACT Bacterial protein translocation is mediated by translocase, a multisubunit membrane protein complex that consists of a peripheral ATPase SecA and a preprotein-conducting channel with SecY, SecE, and SecG as subunits. Like Escherichia coli SecG, theBacillus subtilis homologue, YvaL, dramatically stimulated the ATP-dependent translocation of precursor PhoB (prePhoB) by theB. subtilis SecA-SecYE complex. To systematically determine the functional exchangeability of translocase subunits, all of the relevant combinations of the E. coli and B. subtilis secY, secE, and secG genes were expressed in E. coli. Hybrid SecYEG complexes were overexpressed at high levels. Since SecY could not be overproduced without SecE, these data indicate a stable interaction between the heterologous SecY and SecE subunits. E. coli SecA, but not B. subtilis SecA, supported efficient ATP-dependent translocation of the E. coli precursor OmpA (proOmpA) into inner membrane vesicles containing the hybrid SecYEG complexes, ifE. coli SecY and either E. coli SecE orE. coli SecG were present. Translocation of B. subtilis prePhoB, on the other hand, showed a strict dependence on the translocase subunit composition and occurred efficiently only with the homologous translocase. In contrast to E. coliSecA, B. subtilis SecA binds the SecYEG complexes only with low affinity. These results suggest that each translocase subunit contributes in an exclusive manner to the specificity and functionality of the complex.

Abstract:

Polarized exocytosis plays a major role in development and cell differentiation but the mechanisms that target exocytosis to specific membrane domains in animal cells are still poorly understood. We characterized Drosophila Sec6, a component of the exocyst complex that is believed to tether secretory vesicles to specific plasma membrane sites. sec6 mutations cause cell lethality and disrupt plasma membrane growth. In developing photoreceptor cells (PRCs), Sec6 but not Sec5 or Sec8 shows accumulation at adherens junctions. In late PRCs, Sec6, Sec5, and Sec8 colocalize at the rhabdomere, the light sensing subdomain of the apical membrane. PRCs with reduced Sec6 function accumulate secretory vesicles and fail to transport proteins to the rhabdomere, but show normal localization of proteins to the apical stalk membrane and the basolateral membrane. Furthermore, we show that Rab11 forms a complex with Sec5 and that Sec5 interacts with Sec6 suggesting that the exocyst is a Rab11 effector that facilitates protein transport to the apical rhabdomere in Drosophila PRCs.

Abstract:

Antecedentes y Objetivos: Cosmos secc. Discopoda (Asteraceae, Coreopsideae) es un modelo de estudio sobre poliploidía y aneuploidía. La sección es monofilética, agrupa 24 especies herbáceas perennes y existen especies poliploides y aneuploides. Sin embargo, no se conocen los números cromosómicos para todas las especies y su citogeografía no ha sido estudiada. El propósito de la presente comunicación es dar a conocer conteos cromosómicos para tres especies y discutir sobre el nivel de ploidía ancestral y patrones de distribución geográfica de los niveles de ploidía en la sección.Métodos: Se realizó una recopilación de los registros cromosómicos y se realizaron conteos cromosómicos para tres especies a partir de la preparación de estructuras vegetativas. Mediante un sistema de información geográfica y una base de datos geográficos con 810 registros, se analizó la distribución geográfica de niveles de ploidía asignando un nivel de ploidía a cada registro por especie. Además, se realizó una reconstrucción del nivel de ploidía ancestral mediante análisis empleando un modelo de máxima verosimilitud.Resultados clave: Cosmos nitidus y C. ramirezianus son diploides (2n=2x=24) y C. pseudoperfoliatus es tetraploide (2n=4x=48). En Cosmos secc. Discopoda actualmente se conoce el número cromosómico de 20 especies, 12 son diploides (2n=2x), seis taxa son exclusivamente poliploides (2n=4x, 6x, 8x), cuatro son diploides y poliploides y existen dos eventos independientes de aneuploidía. La reconstrucción del nivel de ploidía ancestral permite reconocer que x=12 es el número cromosómico básico en la sección.Conclusiones: Las especies de Cosmos secc. Discopoda no muestran una correlación entre los niveles de ploidía y sus rangos de distribución geográfica. En contraste, existe un aumento del nivel de ploidía de sur a norte, con una concentración de poliploides en el norte de la Sierra Madre Occidental.

Abstract:

As communities worldwide shift from consuming traditional diets to more processed snacks and sugar-sweetened beverages (SSBs), increases in child obesity and tooth decay and persistence of undernutrition are particularly apparent in Latin American countries. Further evidence of shared risk factors between child undernutrition and poor oral health outcomes is needed to structure more effective health interventions for children’s nutrition. This study aims to identify dietary, oral health, and sociodemographic risk factors for child undernutrition and severe early childhood caries (sECC) among a convenience sample of 797 caregiver–child pairs from rural Salvadoran communities. Caregiver interviews on child dietary and oral health practices were conducted, and their children’s height, weight, and dental exam data were collected. Multivariable regression analyses were performed using RStudio (version 1.0.143). Caregiver use of SSBs in the baby bottle was identified as a common significant risk factor for child undernutrition (p = 0.011) and sECC (p = 0.047). Early childhood caries (p = 0.023) was also a risk factor for developing undernutrition. Future maternal–child health and nutrition programs should coordinate with oral health interventions to discourage feeding children SSBs in the baby bottle and to advocate for policies limiting SSB marketing to young children and their families.

Abstract:

Nell’articolo si tratta l’analisi delle tecniche murarie desunta da dati provenienti da ampi progetti di indagine archeologica svolti in ambito rurale nella Toscana occidentale dalla metà degli anni Novanta dello scorso secolo ad oggi. Nel testo si esaminano i cambiamenti dei modi di edificare a partire dall’edilizia in legno dei primi abitati di altura di VII-VIII secolo, sino agli insediamenti più strutturati di seconda metà VIII e IX secolo, caratterizzati da un primo uso della pietra e dalla presenza di maestranze specializzate. In seguito si analizza la più complessa organizzazione del cantiere propria della costruzione dei castelli di XI e XII secolo in rapporto ai poteri politici ed economici delle nascenti signorie territoriali. Un differente uso delle tecniche costruttive caratterizza la successiva formazione di nuovi borghi tra XIII e XIV secolo, spesso impiantati sui preesistenti castelli, legati ai locali organismi comunali, soggetti all’influenza politica ed economica di Pisa in questo territorio.

Abstract:

Abstract The article analyzes the way to introduce glosses in the vernacular treatises and it therefore concentrates both on Tuscan texts of the 13th and 14th centuries dealing with astronomy, physics, natural philosophy, moral and religious arguments and on the comments of Latin and vernacular works. Corpus OVI database (www.ovi.cnr.it) was used for text search. The study focuses on the connectors between the definiéndum and the defìniens and then deals with the particles or expressions that introduce a gloss and that we have named definition operators. Three operators in particular are used systematically in the vernacular treatises: cioè, tanto è a dire quanto e non è altro che. Cioè introduces a gloss that either simplifies the term being glossed, or provides a variant that facilitates the reader’s comprehension. Whereas tanto è a dire quanto is employed to define loan words from Latin, Greek, Arabic, sometimes even from French, namely terms external to the vernacular language in which the author is writing, while non è altro che introduces a definition based on authority, an undisputable truth, or one that is believed to be undisputable. The constancy and the frequency with which we find especially the last two operators (tanto è a dire quanto and non è altro che) in the genre of texts analyzed make us think of ways followed with awareness by authors, commentators and translators and easily recognized by readers.
