Disparities in childhood obesity highlight the need for research to identify its early predictors in high-risk populations, such as low-income, Latino families. In the current study, the first of its kind in a low-income Latino sample (N = 55; Mchild age = 12.74 months, SD = 3.96), we investigated whether mothers' self-reported attachment style predicted their infants' weight-for-length (WFL; an early indicator of childhood obesity). We also explored whether observed maternal sensitivity, coded from a video-recorded semi-structured play assessment, mediated this association. EN450 clinical trial We found a significant direct effect of maternal attachment style on infants' WFL z-scores (c' = -0.68, SE = 0.22, p = .004). Infants of mothers who classified themselves as secure had lower WFL z-scores than infants of insecure mothers (avoidant or anxious). Maternal sensitivity did not mediate this association, but was positively associated with infant WFL z-scores. We discuss implications of these findings for future research.This article provides a snapshot on the state of thinking about science communication among Lithuanian scientists. It measures scientists' views on public engagement, tests a set of engagement predictors, and explores perceived benefits and barriers to more frequent science-public interactions. Lithuanian scientists are similarly active participants in science communication as their counterparts abroad, but appear to have an understanding of science-public interactions focused on information dissemination. Age, career stage and attitudes to science communication are found to be slightly related to science communication frequency, which is consistent with similar studies conducted across different cultural contexts. Among the perceived barriers to more frequent engagement, Lithuanian scientists cite lack of time and lack of science communication traditions for such activities in the national academic environment. Implications for science communication in Lithuania are discussed.The use of decellularised tissues or organs as cell culture scaffolds has proven to be a promising approach for tissue engineering and regenerative medicine, as these decellularised tissues can provide the instructive niche for cell differentiation and functions. Cartilage is a largely avascular tissue with limited regenerative capacity. Lesions caused by arthritis can lead to severe cartilage degeneration. Previous studies have indicated that decellularized cartilage can be used as scaffolds that support the chondrogenic differentiation of adult stem cells. However, these decellularisation protocols all require the use of denaturing agents, such as high salt and detergents, that lead to the artefactual disruption of the chemical and physical integrity of the tissue microenvironment. Here, we established a new decellularization method for cartilage, through a combined effect of freezing-thawing, sectioning and sonication in water. This protocol achieved the complete removal of cells within minutes, instead of hours or days required by existing procedures, and does not use any detergent. The resulting decellularized cartilage preserved the native ultrastructure and biochemical contents, including glycosaminoglycans which is typically depleted by traditional decellularisation methods. Human mesenchymal stem cells could readily adhere on to the decellularised cartilage. Together, this work unveils that a simple new method for decellularising cartilage, which will be useful in studying how tissue microenvironment supports chondrocyte growth and functions.Background. In the general population, trajectories of walking capacity is accelerated and nonlinear with advanced age. Whether this is more pronounced in persons with multiple sclerosis (pwMS), along with the prevalence of dismobility (ie, slow gait speed), are currently unknown. Our objective was to investigate trajectories of walking capacity and prevalence of dismobility across the adult life span in pwMS versus healthy controls (HC). Methods. Data on maximal timed 25-foot walk test (T25FWT), 2-minute walk test (2MWT), and 6-minute walk test (6MWT) along with prevalence of dismobility were assembled from 2 RIMS multicenter studies (n = 502 pwMS; age range 21-77 years, 6 age groups 20-29, 30-39, 40-49, 50-59, 60-69, and 70-79 years). HC data were extracted from studies containing normative reference values (n = 1070-3780 HC). Results. Age trajectories of walking capacity was nonlinear and accelerated in pwMS versus HC. While measures of walking capacity in pwMS were suppressed already early in life, the gap between pwMS and HC significantly widened across the 6 age groups (pwMS performed 64%, 70%, 57%, 59%, 51%, and 37% of HC, respectively). This coincided with high prevalences of dismobility in pwMS across the 6 age groups when using usual gait speed cut-point values less then 1.0 m/s (corresponding to 33%, 32%, 51%, 59%, 75%, and 100%) and less then 0.6 m/s (corresponding to 19%, 12%, 26%, 23%, 33%, and 43%), markedly exceeding that observed in HC. Conclusion. The present data on walking capacity provide evidence for an accelerated deterioration in pwMS with advanced age, coinciding with high prevalences of dismobility (ie, slow gait speed).Some 5-substituted ribavirin analogues have a high antiviral and anticancer activity, but their mechanisms of action are obviously not the same as their parent compound. The SAR studies performed on 3 (5)-substituted 1,2,4-triazole nucleosides have shown a high dependency between the structure of the 3 (5)-substituent and the level of antiviral/anticancer activity. The most active substances of the row contain coplanar with the 1,2,4-triazole ring aromatic substituent which is connected by a rigid ethynyl bond. However, the compounds with the trans-vinyl linker also had antiviral activity. We decided to study the antitumor activity of ribavirin analogues with alkyl/aryl vinyl substituents in the 5th position of the 1,2,4-triazole ring. Protected nucleoside analogues with various 5-alkylvinyl substituents were obtained by Horner-Wadsworth-Emmons reaction from the common precursor and converted to the nucleosides. Arylvinyl nucleosides were synthesised according the reported procedures. All compounds did not show significant antiproliferative activity on several tumour cell lines.
