Blastocystis spp. is a widely prevalent anaerobic protozoan of uncertain pathogenicity found in the gastrointestinal tracts of over 1 billion people worldwide. Despite its potential significance in health and disease, Blastocystis spp. remains challenging to culture axenically due to its anaerobic nature and the diversity of its genetic subtypes. This manuscript presents a standardized toolkit for culturing Blastocystis spp. in xenic and axenic conditions, detailing protocols for the preparation of appropriate liquid and solid media, cryopreservation, and inoculation. By providing a comprehensive set of tools and methodologies, this work aims to streamline research on Blastocystis spp., enabling reproducibility, subtype characterization, and advancements in understanding its role in the gut microbiome and host health. © 2025 The Author(s).

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.

Latent profile analysis (LPA) is in the finite mixture model analysis family and identifies subgroups by participants' responses to continuous variables (i.e., indicators); participants' probable membership in each subgroup is based on the similarity between the subgroup's prototypical responses and the person's unique responses.

Aims/hypothesis: Alpha cell dysregulation is an integral part of type 2 diabetes pathophysiology, increasing fasting as well as postprandial glucose concentrations. Alpha cell dysregulation occurs in tandem with the development of insulin resistance and changes in beta cell function. Our aim was to investigate, using mathematical modelling, the role of alpha cell dysregulation in beta cell compensatory insulin secretion and subsequent failure in the progression from normoglycaemia to type 2 diabetes defined by ADA criteria.

Despite the widespread utility of transition metal-catalyzed cross-couplings in organic synthesis, the coupling of unactivated alkyl electrophiles remains challenging due to sluggish oxidative addition and competing side reactions. Here, we describe a general and practical copper-catalyzed radical deoxyalkynylation of α-unfunctionalized alcohols through a synergistic combination of Barton-McCombie deoxygenation and copper-catalyzed radical cross-coupling. Key to the success of this method lies in not only the development of rigid anionic multiple N,N,N-ligand to exert remarkable selectivity of highly reactive unactivated alkyl radicals, but also the selection of one suitable oxidant to suppress Glaser homocoupling and other side products.

Introduction: Indonesia comprises 16,771 islands, including 111 small islands and atolls. The Indonesian government has established community health centres, known as puskesmas in Indonesian, to provide health services to the entire populations of the country, including those in remote areas. In 2014, the Indonesian government introduced a national health insurance system with the goal of providing equitable access to health care for all citizens.
