Retinoid signaling in pancreas development, islet function, and disease.

All-trans retinoic acid (ATRA) signaling is essential in numerous different biological contexts. This review highlights the diverse roles of ATRA during development, function, and diseases of the pancreas. ATRA is essential to specify pancreatic progenitors from gut tube endoderm, endocrine and exocrine differentiation, and adult islet function.

SLAMF8 Disrupts Epithelial Barrier in Chronic Rhinosinusitis with Nasal Polyps via M1 Macrophage Polarization.

Background: Recent studies show that M1 macrophages accumulate predominantly in non-eosinophilic chronic rhinosinusitis with nasal polyps (neCRSwNP). However, the precise mechanisms regulating M1 macrophages and their impact on the epithelial barrier remain unclear.

Objective: We aim to investigate the expression and regulatory role of SLAMF8, a molecule exclusively expressed in myeloid cells, in M1 macrophage polarization and its potential contribution to neCRSwNP development.

Effect of the variant rs7903146 of Transcription factor 7-like 2(TCF7L2) gene on anthropometric and metabolic responses to a 24 weeks meal replacement Hypocaloric diet.

Introduction: Some studies have demonstrated the effect of the rs7903146 genetic variant on weight response after different dietary strategies. The objective of our study was to evaluate the role of this genetic variant of the TCF7L2 gene on weight loss and diabetes mellitus progression following a partial meal replacement (pMR) hypocaloric diet.

Methods: We conducted an interventional study in 214 subjects with obesity and a body mass index (BMI) > 35 kg/m².

cord blood metabolite profiles and childhood cardio-metabolic outcomes in a population-based cohort.

Introduction: Adverse exposures in utero might cause adaptations of cardiovascular and metabolic organ development, predisposing individuals to an adverse cardio-metabolic risk profile from childhood onwards. We hypothesized that adaptations in metabolic pathways underlie these associations and examined associations of metabolite profiles at birth with childhood cardio-metabolic risk factors.

Methods: The study included 763 mother-child pairs participating in an ongoing population-based prospective cohort study with an overall low disease risk.

Health Expenditures of Patients With Diabetes After Bariatric Surgery: Comparing Gastric Bypass and Sleeve Gastrectomy.

Background: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) differ in their effects on body weight and risk for reoperation. However, it is unclear whether long-term health expenditures differ by procedure type in patients with diabetes.

Objective: To compare health expenditures 3 years before and 5.

The Association of Epstein-Barr Virus Donor and Recipient Serostatus With Outcomes After Kidney Transplantation : A Retrospective Cohort Study.

Background: Prior studies indicate that 1% to 4% of Epstein-Barr virus (EBV)-seronegative recipients of EBV-seropositive donor (EBV D+/R-) kidneys develop posttransplant lymphoproliferative disorder (PTLD). However, these estimates are based on limited data that lack granularity.

Objective: To determine the associations between pretransplant EBV D+/R- and recipient EBV-seropositive status (R+) and the outcomes of PTLD and graft and patient survival among adult kidney transplant recipients.

Guidelines International Network: Principles for Use of Artificial Intelligence in the Health Guideline Enterprise.

Description: Artificial intelligence (AI) has been defined by the High-Level Expert Group on AI of the European Commission as "systems that display intelligent behaviour by analysing their environment and taking actions-with some degree of autonomy-to achieve specific goals." Artificial intelligence has the potential to support guideline planning, development and adaptation, reporting, implementation, impact evaluation, certification, and appraisal of recommendations, which we will refer to as "guideline enterprise." Considering this potential, as well as the lack of guidance for the use of AI in guidelines, the Guidelines International Network (GIN) proposes a set of principles for the development and use of AI tools or processes to support the health guideline enterprise.

Effects of Noise and Public Setting on Blood Pressure Readings : A Randomized Crossover Trial.

Background: Guidelines emphasize quiet settings for blood pressure (BP) measurement.

Objective: To determine the effect of noise and public environment on BP readings.

Design: Randomized crossover trial of adults in Baltimore, Maryland.

Combined intrathecal baclofen pump revision to the cervical level and lumbosacral ventral-dorsal rhizotomy for severe medically refractory hypertonia: illustrative cases.

Background: Medically refractory hypertonia (MRH) within the pediatric population causes severe disability and is difficult to treat. Neurosurgery for mixed MRH includes intrathecal baclofen (ITB) and lumbosacral ventral-dorsal rhizotomy (VDR). Surgical efficacy limitations can be mitigated by combining the two into a multimodal strategy.

Protection of β2GPI-Deficient Mice from Thrombosis Reflects a Defect in PAR3-facilitated Platelet Activation.

Antibodies to β2-glycoprotein I (β2GPI) cause thrombosis in antiphospholipid syndrome, however the role of β2GPI in coagulation in vivo is not understood. To address this issue, we developed β2GPI-deficient mice (Apoh-/-) by deleting exon 2 and 3 of Apoh using CRISPR/Cas9 and compared the development of thrombosis in wild-type (WT) and Apoh-/- mice using rose bengal and FeCl3-induced carotid thrombosis, laser-induced cremaster arteriolar injury, and inferior vena cava (IVC) stasis models. We also compared tail bleeding times and activation of platelets from WT and Apoh-/- mice in the absence and presence of β2GPI.

Is Ockham's razor losing its edge? New perspectives on the principle of model parsimony.

The preference for simple explanations, known as the parsimony principle, has long guided the development of scientific theories, hypotheses, and models. Yet recent years have seen a number of successes in employing highly complex models for scientific inquiry (e.g.

Small molecule modulators of B56-PP2A restore 4E-BP function to suppress eIF4E-dependent translation in cancer cells.

Dysregulated eIF4E-dependent translation is a central driver of tumorigenesis and therapy resistance. eIF4E binding proteins (4E-BP1/2/3) are major negative regulators of eIF4E-dependent translation that are inactivated in tumors through inhibitory phosphorylation or downregulation. Previous studies have linked PP2A phosphatase(s) to activation of 4E-BP1.

M-Sec promotes the accumulation of intracellular HTLV-1 Gag puncta and the incorporation of Env into viral particles.

We have demonstrated that the cellular protein M-Sec promotes the transmission of human T-cell leukemia virus type 1 (HTLV-1) in vitro and in vivo. Here, we show how HTLV-1 utilizes M-Sec for its efficient transmission. HTLV-1-infected CD4+ T cells expressed M-Sec at a higher level than uninfected CD4+ T cells.

Remote neurodegeneration in the lumbosacral cord one month after spinal cord injury: a cross-sectional MRI study.

Objective: To characterize structural integrity of the lumbosacral enlargement and conus medullaris within one month after spinal cord injury (SCI).

Methods: Lumbosacral cord MRI data were acquired in patients with sudden onset (<7 days) SCI at the cervical or thoracic level approximately one month after injury and in healthy controls. Tissue integrity and loss were evaluated through diffusion tensor (DTI) and T2*-weighted imaging (cross-sectional area [CSA] measurements).

CSF cytokine, chemokine and injury biomarker profile of glial fibrillary acidic protein (GFAP) autoimmunity.

Defining the CSF cytokine/chemokine and injury biomarker signature of glial fibrillary acidic protein (GFAP) autoimmunity can inform immunopathogenesis. CSF GFAP-IgG-positive samples (N = 98) were tested for 17 cytokines/chemokines, neurofilament light chain (NfL), and GFAP (ELLA, Bio-Techne). Controls included non-inflammatory (N = 42), AQP4-IgG-positive (N = 83), CNS infections (N = 13), and neurosarcoidosis (N = 32).

An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis.

Objective: To assess the pathological mechanisms contributing to white matter (WM) lesion expansion or contraction and remyelination in multiple sclerosis (MS).

Methods: We assessed 1,613 lesions in 49 people with relapsing-remitting MS in the CCMR-One bexarotene trial (EudraCT 2014-003145-99). We measured lesion orientation relative to WM tracts, surface-in gradients and veins.
