Chemically inert and biocompatible boron-doped diamond (BDD) has been successfully used in neuroscience for sensitive neurochemicals sensing and/or as a growth substrate for neurons. In this study, several types of BDD differing in (i) fabrication route, i.e. conventional microwave plasma enhanced chemical vapour deposition (MW-PECVD) reactor vs. MW-PECVD with linear antenna delivery system, (ii) morphology, i.e. planar vs. porous BDD, and (iii) surface treatment, i.e. H-terminated (H-BDDs) vs. O-terminated (O-BDDs), were characterized from a morphological, structural, and electrochemical point of view. Further, planar and porous BDD-based electrodes were tested for sensing of dopamine in common biomimicking environments of pH 7.4, namely phosphate buffer (PB) and HEPES buffered saline (HBS). In HBS, potential windows are narrowed due to electrooxidation of its buffering component (i.e. HEPES), however, dopamine sensing in HBS is possible. H-BDDs (both planar and porous) outperformed O-BDDs as they provided clearer dopamine signals with higher peak currents. As expected, due to its enlarged surface area and increased sp2 content, the highest sensitivity and lowest detection limits of 8 × 10-8 mol L-1 and 6 × 10-8 mol L-1 in PB and HBS media, respectively, were achieved by square-wave voltammetry on porous H-BDD.

To examine the experiences and needs of Asian older adults who are socially isolated and lonely living in Asian and western countries.

Six databases were searched for qualitative studies from each database's inception to December 2019. Qualitative data were meta-summarized and then meta-synthesized.

Fourteen studies were included in this review. Five themes emerged (1) association with older adults' well-being, (2) loss of social support, (3) dealing with social isolation and loneliness (4) unique experiences of Asian older adults in western countries, and (5) wish list of older adults. The older adults felt psychologically down and experienced a lack of social support from their family members. They coped using strategies such as religious reliance and social engagement with peers. Smad3 signaling Asian older adults in western countries faced cultural barriers and tried to form ethnic communities. The older adults wished for more community resources and care.

There were multiple associations of social isolation and d active coping strategies are proposed and can be incorporated in healthcare services and social programs to assist these older adults.

Sexual minority youth experience worse mental health compared to their heterosexual peers, reflecting the consequences of sexual minority-based stigma. Previous research has focused on contextual variation to understand variability within this vulnerability. Childhood temperament factors such as negative affect, effortful control and surgency/extraversion are important for understanding differential susceptibility to environmental stressors. The objective of the current study was to understand how childhood temperament factors, measured prior to the most difficult developmental period for sexual minority youth, moderated the association between sexual minority status and internalizing and externalizing behavior problems.

Youth reporting same-sex attraction in an ongoing longitudinal project on the development of conduct problems in Quebec, Canada were matched with heterosexual peers, for an analytic sample of 280 youth (62% girls). Structural equation models were used to examine (1) the association betweeeported mental health among sexual minority youth, and supports the use of developmental constructs like temperament to better understand vulnerability to psychosocial difficulties within this population.Conventional wisdom holds that tea (Camellia sinensis) quality can be improved by drought. To clarify the underlying mechanism, a conjoint analysis of transcriptome and metabolome profiling was carried out in tea shoots harvested under different soil water contents (SWCs). Drought had little impact on theanine, catechins and caffeine in field conditions. Besides the flavor contributions of amino acid and their derivatives, organic acids, and nucleotides and their derivatives, the obviously increased isoflavonoids and glycosylflavonoids and the sharply decreased lipids are suggested to play key roles, which is mainly due to substantial increases of type III polyketide synthase B (PKSB), flavonol synthase/flavanone 3-hydroxylase (FLS), and UDP-glycosyltransferases (UGTs), as well as the significant repression of anthocyanidin synthase (ANS) and R2R3MYBs, and downregulated lipid metabolisms. Genes of GDSL esterase/lipase (GDSL), abscisic acid (ABA) and jasmonate (JA) signaling were found to play important roles in both flavonoid accumulation and lipid reduction. These findings increased our understanding of how moderate drought improves taste and aroma of tea by interfering in the metabolism of fresh leaves, which provides new insight into balancing compounds in pre-harvest tea shoots.One of the main goals of the Spanish and Portuguese-Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) is to promote and contribute to the development and dissemination of scientific knowledge in the field of forensic genetics. The GHEP-ISFG supports several Working Commissions which develop different scientific activities. One of them, the Working Commission on "Massively Parallel Sequencing (MPS) Forensic Applications", organized its first collaborative exercise on forensic applications of MPS technology in 2019. The aim of this exercise was to assess the concordance between the MPS results and those obtained with conventional technologies (capillary electrophoresis and Sanger sequencing), as well as to compare the results obtained within the different MPS platforms and/or the different kits/panels and analysis software packages (commercial and open-access) available on the market. The seven participating laboratories analyzed some samples of the annual GHEP-ISFG proficienzation of the nomenclature for STRs analyzed by sequencing with MPS, the universal uptake of a nomenclature framework by the analysis software, and well established validation and accreditation of the new MPS platforms for use in routine forensic case-work.
