The outcome of intra-cytoplasmic sperm injection (ICSI): do the sperm concentration and motility matter?

Horm Mol Biol Clin Investig 2021 Jun 14. Epub 2021 Jun 14.

Advanced Reproductive Centre (ARC), Hospital Canselor Tuanku Muhriz (HCTM), Kuala Lumpur, Malaysia.

Objectives: The male-factor subfertility was reported to be 30% globally; thus, the intracytoplasmic sperm injection (ICSI) procedure was implemented to improve the overall fertilization (IVF) rates. Nevertheless, at least 10% of fertilization failure still occurs. Concerning this issue, we explored the association of sperm concentration and motility with the quality of embryo development and pregnancy outcome in IVF-ICSI cycles. Read More

Postexercise hypotension due to resistance exercise is not mediated by autonomic control: A systematic review and meta-analysis.

Auton Neurosci 2021 May 27;234:102825. Epub 2021 May 27.

Department of Kinesiology, University of Connecticut, Storrs, CT, USA.

Changes in autonomic control have been suggested to mediate postexercise hypotension (PEH). We investigated through meta-analysis the after-effects of acute resistance exercise (RE) on blood pressure (BP) and autonomic activity in individuals with normal and elevated BP. Electronic databases were searched for trials including: adults; exclusive RE interventions; and BP and autonomic outcomes measured pre- and postintervention for at least 30 min. Read More

Virtual population generation is an emerging field in data science with numerous applications in healthcare towards the augmentation of clinical research databases with significant lack of population size. However, the impact of data augmentation on the development of AI (artificial intelligence) models to address clinical unmet needs has not yet been investigated. In this work, we assess whether the aggregation of real with virtual patient data can improve the performance of the existing risk stratification and disease classification models in two rare clinical domains, namely the primary Sjögren's Syndrome (pSS) and the hypertrophic cardiomyopathy (HCM), for the first time in the literature.

Metagenomic insights into the effect of thermal hydrolysis pre-treatment on microbial community of an anaerobic digestion system.

Sci Total Environ 2021 Jun 1;791:148096. Epub 2021 Jun 1.

Advanced Environmental Biotechnology Centre, Nanyang Environment and Water Research Institute, Nanyang Technological University, Singapore 637141, Singapore; School of Civil and Environmental Engineering, Nanyang Technological University, Singapore 639798, Singapore. Electronic address:

Thermal hydrolysis process (THP) is an effective pre-treatment method to reduce solids volume and improve biogas production during anaerobic digestion (AD) via increasing the biodegradability of waste activated sludge (WAS). However, the effects of THP pre-treated sludge on microbial diversity, interspecies interactions, and metabolism in AD systems remain largely unknown. We therefore setup and operated an anaerobic digester during a long-term period to shed light on the effect of THP pre-treatment on AD microbial ecology in comparison to conventional AD via Illumina based 16S rRNA gene amplicon sequencing and genome-centric metagenomics analysis.

Faculty of Medicine, School of Medicine, National Yang-Ming University, Taipei, Taiwan; Heart Rhythm Center, Division of Cardiology, Department of Medicine, Taipei Veterans General Hospital, Taipei, Taiwan.

ALDH2 gene is coded for the aldehyde dehydrogenase (ALDH), which is an enzyme involved in alcohol metabolism. Compared to normal aldehyde dehydrogenases, a homozygous point mutation on exon 12 from G to A significantly reduces its efficiency. In this study, we have reported the generation of IBMS-iPSC-021-04, IBMS-iPSC-022-01, and IBMS-iPSC-023-03 as induced pluripotent stem cell (iPSC) lines carrying the homozygous form of ALDH2 with the rs671 genetic polymorphism (E487K mutation).

Department of Chemistry, University of Houston, Houston, TX 77204, USA. Electronic address:

Superoxide Dismutase 1 (SOD1) is an antioxidant enzyme that protects the cells from radical oxygen species. To study the behavior of endogenous SOD1 under a microscope, we genetically modified H1 human embryonic stem cells (hESCs) to express SOD1 fused with a SNAP-tag, a protein tag that can be covalently labeled with a variety of synthetic probes. The engineered homozygous clone expressing SOD1-SNAP fusion proteins has normal stem cell morphology and karyotype, expresses pluripotency markers, and can be differentiated into all three germ layers in vitro, providing a versatile platform for imaging-based studies of SOD1.

Psychiatry Res 2021 May 27;302:114030. Epub 2021 May 27.

Alkermes, Inc., Waltham, MA, USA.

One strategy to address hyperprolactinemia and associated sexual side effects in patients receiving antipsychotics is switching to an antipsychotic not associated with prolactin elevation (eg, aripiprazole). This post hoc analysis assessed prolactin concentrations and sexual side effects in an open-label prospective study of switching long-acting injectable antipsychotics from paliperidone palmitate (PP) to aripiprazole lauroxil (AL). Serum prolactin was measured throughout the study. Read More

K channel blockers control glucagon secretion by distinct mechanisms: a direct stimulation of α-cells involving a [Ca] rise and an indirect inhibition mediated by somatostatin.

Mol Metab 2021 Jun 9:101268. Epub 2021 Jun 9.

Université Catholique de Louvain, Institut de Recherche Expérimentale et Clinique, Pôle d'Endocrinologie, Diabète et Nutrition, Brussels, Belgium. Electronic address:

Objective: Glucagon is secreted by pancreatic α-cells in response to hypoglycemia and its hyperglycemic effect helps to restore normal blood glucose. Insulin and somatostatin (SST) secretions from β- and δ-cells, respectively, are stimulated by glucose by mechanisms implicating an inhibition of their ATP-sensitive K (K) channels, leading to an increase in [Ca] that triggers exocytosis. Drugs that close K channels, such as sulfonylureas, are used to stimulate insulin release in type 2 diabetic patients. Read More

Electronic address:

Fecal microbiota transplantation (FMT) of human fecal samples into germ-free (GF) mice is useful for establishing causal relationships between the gut microbiota and human phenotypes. However, due to the intrinsic differences between human and mouse intestines and the different diets of the two organisms, it may not be possible to replicate human phenotypes in mice through FMT; similarly, treatments that are effective in mouse models may not be effective in humans. In this study, we aimed to identify human gut microbes that undergo significant and consistent changes (i. Read More

Circadian clock genes as promising therapeutic targets for autoimmune diseases.

Autoimmun Rev 2021 Jun 9:102866. Epub 2021 Jun 9.

Department of Nephrology, The Second Affiliated Hospital of Anhui Medical University, Hefei, Anhui, China. Electronic address:

Circadian rhythm is a natural, endogenous process whose physiological functions are controlled by a set of clock genes. Disturbance of the clock genes have detrimental effects on both innate and adaptive immunity, which significantly enhance pro-inflammatory responses and susceptibility to autoimmune diseases via strictly controlling the individual cellular components of the immune system that initiate and perpetuate the inflammation pathways. Autoimmune diseases, especially rheumatoid arthritis (RA), often exhibit substantial circadian oscillations, and circadian rhythm is involved in the onset and progression of autoimmune diseases.
