Myelin transcription factors 1 and 3 have overlapping but distinct roles in insulin secretion and survival of human β cells.

Unlabelled: Islet β-cell dysfunction, loss of identity, and death, together known as β-cell failure, lead to reduced inulin output and Type 2 diabetes (T2D). Understanding how β-cells avoid this failure holds the key to preventing or delaying the development of this disease. Here, we examine the roles of two members of the Myelin transcription factor family (including MYT1, 2, and 3) in human β-cells.

Throw and Catch: Analyzing the Synchronized Movements of Eyes and Joints in Children.

Throw and catch are fundamental motor skills that are closely related to eye-hand coordination, reaction speed, and spatial awareness in children. Current research on throw and catch mainly focuses on the impact of attentional focus, anticipatory knowledge, and training on visuomotor control. Little work has been done on the synchronized movements of eyes and joints during the throw and catch.

Background: Recovery of upper limb function after stroke secondary to ischemia or hemorrhage is crucial for patients' independence in daily living and quality of life. Virtual reality (VR) is a promising computer-based technology designed to enhance the effects of rehabilitation; however, the results of VR-based interventions remain equivocal.

Objective: This study aims to review the plausible factors that may have influenced VR's therapeutic effects on improving upper limb function in patients with stroke, with the goal of synthesizing an optimal VR intervention protocol.

Smaller follicle diameter improves outcomes in natural LPOS: a retrospective cohort study.

Background: This study aimed to investigate the optimal follicular diameter at the initiation of luteal-phase ovarian stimulation (LPOS) protocol after natural ovulation to achieve better laboratory outcomes.

Methods: This retrospective cohort study analyzed 286 in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) cycles in patients who began the LPOS protocol after natural ovulation. Patients were categorized into three groups based on follicle diameter at initiation: small diameter follicles (SDF, < 5 mm, n = 74), medium diameter follicles (MDF, 5.

Comparison of vaginal versus intramuscular progesterone in programmed cycles for frozen-thawed blastocyst transfer in patients with endometriosis.

Background: Previous studies have shown that due to the presence of endometrium progesterone resistance in patients with endometriosis, it is considered that higher levels of progesterone may be required to achieve live birth during programmed frozen-thawed embryo transfer (FET) cycles. Currently, the optimal progesterone support in FET cycles remains a contentious issue, and it mainly focused on the general infertile population, without specific attention to infertile patients with endometriosis. This study aimed to compare the pregnancy outcomes between vaginal or intramuscular progesterone administration in patients with endometriosis, and to determine whether the stage of endometriosis moderates the differences.

A survey on the current status of transportation travel among people with epilepsy in China.

Objective: In China, motor vehicles and non-motorized vehicles (bicycles or e-bikes) are the most common modes of transportation. However, individuals with epilepsy may face significant challenges and barriers when using these modes of transportation. This study aims to assess the current status and challenges faced by people with epilepsy in terms of transportation.

Atf4 protects islet β-cell identity and function under acute glucose-induced stress but promotes β-cell failure in the presence of free fatty acid.

Glucolipotoxicity, caused by combined hyperglycemia and hyperlipidemia, results in β-cell failure and type 2 diabetes via cellular stress-related mechanisms. Activating transcription factor 4 (Atf4) is an essential effector of stress response. We show here that Atf4 expression in β-cells is minimally required for glucose homeostasis in juvenile and adolescent mice but it is needed for β-cell function during aging and under obesity-related metabolic stress.

Serum neuritin as a predictive biomarker of early neurological deterioration and poor prognosis after spontaneous intracerebral hemorrhage: a prospective cohort study.

Objective: Intracerebral hemorrhage (ICH) is a common cerebrovascular disease characterized by high mortality and disability rates. Neuritin, significantly expressed in injured brain tissues, is implicated in the molecular mechanisms underlying acute brain injury. We aimed to explore the prognostic and predictive value of serum neuritin in ICH.

Pathobiont-triggered induction of epithelial IDO1 drives regional susceptibility to Inflammatory Bowel Disease.

The structure and function of the mammalian gut vary by region, yet why inflammatory diseases manifest in specific regions and not others remains unclear. We use a TNF-overexpressing Crohn's disease (CD) model (Tnf), which typically presents in the terminal ileum (TI), to investigate how environmental factors interact with the host's immune susceptibility to drive region-specific disease. We identified an intracellular bacterium and murine counterpart to the human sexually transmitted , as necessary and sufficient to trigger disease manifestation in the ascending colon (AC), another common site of human CD.

Smartphone-based mobile digital pressure sensor for quantitative point-of-care testing of respiratory syncytial virus infection.

Respiratory syncytial virus (RSV) is a major cause of acute respiratory tract infections in infants and elderly individuals, leading to hospitalisation and potentially fatal outcomes, posing a serious threat to global health and economy. This study proposes a smartphone-based mobile digital pressure sensor (smartphone-MDPS) for the quantitative detection of the RSV fusion protein (RSV-F) in clinical nasopharyngeal samples. The smartphone-MDPS utilized two monoclonal antibodies (mAbs) specific to the F protein, of which mAb1 was conjugated with Au@PtNPs (Au@PtNPs-mAb1) as the detection antibody and mAb2 was coupled with magnetic beads (MB-mAb2) as a coating antibody to establish a novel sandwich immunoassay.

Pretreatment with oral contraceptive pills in women with PCOS scheduled for IVF: a randomized clinical trial.

Study Question: What is the effect of pretreatment with oral contraceptive pills (OCPs) on oocyte and embryo quality and pregnancy rates in women with polycystic ovary syndrome (PCOS) scheduled for IVF/ICSI cycles?

Summary Answer: In women with PCOS who underwent a first or second IVF/ICSI cycle with a GnRH antagonist protocol and were randomized to start ovarian stimulation immediately, the quality of cleavage-stage embryos was non-inferior to pretreatment with OCP.

What Is Known Already: PCOS in Asian populations is characterized by high levels of circulating LH in the early follicular phase. Previous studies indicated that inappropriately high LH levels might affect oocyte maturation and fertilization rates, and impaired embryo quality, consequently resulting in higher rates of impaired pregnancy and miscarriage in women with PCOS.

Serum Progesterone Level on the Day of Embryo Transfer Is Not a Reliable Predictor for Frozen-Thawed Embryo Transfer Outcomes With Euploid Blastocyst Transfer: A Retrospective Cohort Study.

Objective: To investigate whether serum progesterone (P4) levels on embryo transfer (ET) day correlate with the likelihood of live birth in artificial frozen-thawed transfer cycles using intramuscular progesterone.

Design: Retrospective cohort study.

Setting: University-affiliated hospital.

Unsaturated fatty acid profiles and prognostic significance in epilepsy patients: A comprehensive analysis using UPLC-MS/MS and SVM algorithm.

Unsaturated fatty acids (UFAs) play a crucial physiological role in human body. However, the concentration-related changes and prognostic significance of UFAs in epilepsyremain unclear. An optimized ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) approach was developed to measure six key UFAs: oleic acid (OA), linoleic acid (LA), arachidonic acid (AA), α-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA).

Methods: Eighty-six pediatric patients with colonic ulcers detected by colonoscopy were enrolled in the retrospective study.

Temporal recording of mammalian development and precancer.

Temporal ordering of cellular events offers fundamental insights into biological phenomena. Although this is traditionally achieved through continuous direct observations, an alternative solution leverages irreversible genetic changes, such as naturally occurring mutations, to create indelible marks that enables retrospective temporal ordering. Using a multipurpose, single-cell CRISPR platform, we developed a molecular clock approach to record the timing of cellular events and clonality in vivo, with incorporation of cell state and lineage information.

To showcase the platform capability, the smartphone-based immunochromatography system (SPICS) reader and device were successfully used in CNP strips for rapid detection of the early pregnancy marker human chorionic gonadotropin in female urine (HCG; limit of detection [LOD]: 0.

Identification and multimodal characterization of a specialized epithelial cell type associated with Crohn's disease.

Crohn's disease (CD) is a complex chronic inflammatory disorder with both gastrointestinal and extra-intestinal manifestations associated immune dysregulation. Analyzing 202,359 cells from 170 specimens across 83 patients, we identify a distinct epithelial cell type in both terminal ileum and ascending colon (hereon as 'LND') with high expression of LCN2, NOS2, and DUOX2 and genes related to antimicrobial response and immunoregulation. LND cells, confirmed by in-situ RNA and protein imaging, are rare in non-IBD controls but expand in active CD, and actively interact with immune cells and specifically express IBD/CD susceptibility genes, suggesting a possible function in CD immunopathogenesis.

Efficacy of NKG2D CAR-T cells with IL-15/IL-15Rα signaling for treating Epstein-Barr virus-associated lymphoproliferative disorder.

Epstein-Barr virus (EBV) related post-transplant lymphoproliferative disorder (EBV-PTLD) is a life-threatening complication after hematopoietic stem cell transplantation (HSCT) or solid organ transplantation (SOT), for which no standard therapeutic means have been developed. Significant increase expression of natural killer group 2 member D ligands (NKG2DLs) was observed on B-lymphoblastoid cells of EBV-PTLD, indicating NKG2DLs as potential therapeutic targets for treatment of EBV-PTLD. In this study, the recombinant constructs of NKG2D CAR and IL-15/IL-15Rα-NKG2D CAR were generated with a retroviral vector and then transduced to human T cells to produce NKG2D CAR-T and IL-15/IL-15Rα-NKG2D CAR-T cells, respectively.
