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. 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. selleck chemical 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 c
