Boosting bulk photovoltaic effect in transition metal dichalcogenide by edge semimetal contact.

Oxide materials with a non-centrosymmetric structure exhibit bulk photovoltaic effect (BPVE) but with a low cell efficiency. Over the past few years, relatively larger BPVE coefficients have been reported for two-dimensional (2D) layers and stacks with asymmety-induced spontaneous polarization. Here, we report a crucial breakthrough in boosting the BPVE in 3R-MoS by adopting edge contact (EC) geometry using bismuth semimetal electrode.

Targeting sirtuins in neurological disorders: A comprehensive review.

The sirtuin (SIRT) family is a group of seven conserved nicotinamide adenine dinucleotide-dependent histone deacetylases (SIRT1-SIRT7), which play crucial roles in various fundamental biological processes, including metabolism, aging, stress responses, inflammation, and cell survival. The role of SIRTs in neuro-pathophysiology has recently attracted significant attention. Notably, SIRT1-SIRT3 have been identified as key players in neuroprotection as they reduce neuroinflammation and regulate mitochondrial function.

6-month regimen of isoniazid prevention therapy for tuberculosis among people living with human immunodeficiency virus in minority areas of China: a 3-year prospective cohort study.

Introduction: As China is scaling up tuberculosis preventive therapy (TPT) for people living with HIV (PLHIV) in its national programmes, the objective of this study was to evaluate the feasibility and performance of 6-month regimen of isoniazid monotherapy (6H) in terms of preventive therapy acceptance, adherence, effectiveness and outcomes in minority areas with a high burden of tuberculosis (TB) and HIV/AIDS.

Method: A prospective observational cohort study was initiated among 461 PLHIV in Butuo County after ruling out active TB (ATB) and followed up for up to 3 years to collect incidence events in real-world settings. TB incidence and protective rates were calculated.

Multi-way overlapping clustering by Bayesian tensor decomposition.

The development of modern sequencing technologies provides great opportunities to measure gene expression of multiple tissues from different individuals. The three-way variation across genes, tissues, and individuals makes statistical inference a challenging task. In this paper, we propose a Bayesian multi-way clustering approach to cluster genes, tissues, and individuals simultaneously.

Design and Synthesis of Completely Nonfused Medium-Wide-Bandgap Acceptors for Efficient Organic Photovoltaic Cells.

Medium-wide-bandgap (MWBG) organic photovoltaic (OPV) cells have emerged as a promising category with distinctive application possibilities, especially in environments characterized by specific light conditions, such as indoor spaces. However, there are few high-efficiency MWBG acceptors, and most of them are constructed through high-cost fused central units, which limits the industrialization of MWBG OPV cells. Here, two completely nonfused MWBG acceptors, TBT-38 and TBT-43 with different alkoxy substituent positions on the thiophene rings, are synthesized.

Graphical Dirichlet Process for Clustering Non-Exchangeable Grouped Data.

We consider the problem of clustering grouped data with possibly non-exchangeable groups whose dependencies can be characterized by a known directed acyclic graph. To allow the sharing of clusters among the non-exchangeable groups, we propose a Bayesian nonparametric approach, termed graphical Dirichlet process, that jointly models the dependent group-specific random measures by assuming each random measure to be distributed as a Dirichlet process whose concentration parameter and base probability measure depend on those of its parent groups. The resulting joint stochastic process respects the Markov property of the directed acyclic graph that links the groups.

Cerebral vascular malformations: pathogenesis and therapy.

Cerebral vascular malformations (CVMs), particularly cerebral cavernous malformations and cerebral arteriovenous malformations, pose significant neurological challenges due to their complex etiologies and clinical implications. Traditionally viewed as congenital conditions with structural abnormalities, CVMs have been treated primarily through resection, embolization, and stereotactic radiosurgery. While these approaches offer some efficacy, they often pose risks to neurological integrity due to their invasive nature.

ADAM10-mediated β-klotho degradation: a key to FGF21 resistance in senescent vascular endothelial cells.

Fibroblast growth factor 21 (FGF21) is a key regulator of metabolism and cardiovascular health. However, its upregulation in aging and age-related disorders suggests the presence of FGF21 resistance. This study aimed to elucidate the mechanisms underlying senescence-associated FGF21 resistance in human umbilical vein endothelial cells (HUVECs) and to explore potential therapeutic interventions.

Aromatic components are vital for the flavor profile of peaches. This study investigated the aroma compounds of 20 differential peach cultivars using headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). A total of 82 distinct aromas were identified, comprising 6 lactones, 16 esters, 24 alcohols, 5 aldehydes, 12 ketones, and 19 other compounds.

A novel homozygous mutation in the NLRP2 gene causes early embryonic arrest.

Purpose: Successful reproduction in humans requires maturation and fertilization of gametes as well as early embryonic development. Any deviation from these processes leads to infertility. Early embryonic arrest (EEA) is common in female infertility and is primarily attributed to genetic factors.

rTM reprograms macrophages via the HIF-1α/METTL3/PFKM axis to protect mice against sepsis.

The metabolic reprogramming of macrophages is a potential therapeutic strategy for sepsis treatment, but the mechanism underlying this reprogramming remains unclear. Since glycolysis can drive macrophage phenotype switching, the rate-limiting enzymes in glycolysis may be key to treating sepsis. Here, we found that, compared with other isoenzymes, the expression of 6-phosphofructokinase, muscle type (PFKM) was the most upregulated in monocytes from septic patients.

Iron Deficiency and Internalizing Symptoms Among Adolescents in the National Health and Nutrition Examination Survey.

Background: Iron Deficiency (ID) affects two billion people worldwide, predominantly adolescent girls, and may be associated with increased psychopathology. The associations between ID and symptoms of depression and anxiety in adolescents were examined using data from the National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey of a nationally representative sample of non-institutionalized Americans.

Methods: The current analysis included survey cycles where both iron-related markers and mental health-related outcomes were collected in adolescents 12 to 17 years old.

Covariate-Assisted Bayesian Graph Learning for Heterogeneous Data.

In a traditional Gaussian graphical model, data homogeneity is routinely assumed with no extra variables affecting the conditional independence. In modern genomic datasets, there is an abundance of auxiliary information, which often gets under-utilized in determining the joint dependency structure. In this article, we consider a Bayesian approach to model undirected graphs underlying heterogeneous multivariate observations with additional assistance from covariates.

However, the use of halogen solvents in the fabrication of OPV cells raises concerns due to their potential environmental and health impacts. In this work, a novel non-fullerene small molecule acceptor BO-AM-4F, featuring an asymmetric alkyl chain design that includes a 2-butyloctyl and a unique 6-(hexylamino)-6-oxohexyl chain is synthesized.

Causality between immunocytes and polymyositis: A Mendelian randomization analysis.

Polymyositis is a prominent subgroup of idiopathic inflammatory myopathy, considered to have an autoimmune etiology. However, research exploring the condition between immunocytes and polymyositis remains limited, indicating the need for further investigation to unravel these intricate associations. We employed bidirectional Mendelian randomization (MR) analysis to ascertain causality between 731 immunocytes and polymyositis.

The Toll-like receptor 4 antagonist TAK-242 in combination with sodium hyaluronate alleviates postoperative abdominal adhesion in a mouse model.

Postoperative abdominal adhesion is one of the most common complications after abdominal surgery. The Toll-like receptor 4 (TLR4) signaling pathway is one of the most common inflammation-related pathways, and it has been demonstrated that TLR4 is highly expressed in adhesive tissues; however, the function of TLR4 in adhesion formation has not yet been studied. In the present study, the expression of TLR4 was first detected by immunohistochemical (IHC) and double-immunofluorescence staining in 40 mice, which were randomly divided into four groups, and sacrificed at 1, 3, 5 and 7 days after surgery.
