Sepsis, a condition of significant clinical concern, is characterized by life-threatening organ dysfunction that arises from an infection and is exacerbated by a dysregulated host response. Targeting immune modulation, particularly against tumor necrosis factor-alpha (TNF-α), has emerged as a promising anti-inflammatory therapeutic strategy. However, approaches such as blood purification to eliminate inflammatory mediators or the use of anti-TNF-α therapies have shown limited efficacy in clinical practice.

We revealed a collection of candidate genes located in 30 genomic loci under positive selection. Among them, MCUR1 at 6p23 was a novel pronounced candidate.

Introduction: Smoking is associated with significant alterations in sleep architecture. Previous studies have revealed changes in the subjective sleep of young smokers, but research on objective sleep assessment using polysomnography (PSG) is limited. This study aims to explore electroencephalography (EEG) power and sleep spindle activity during the sleep of young smokers, as well as to assess the relationship between sleep and smoking variables.

Conventional insecticide-based pest control faces challenges such as human and environmental toxicity and resistance. As alternative solutions, pheromone-based repellents have emerged as a promising approach.

As a critical cell-surface receptor, TNFR1 regulates key signaling pathways, such as nuclear factor kappa-B (NF-κB) and mitogen-activated protein kinase (MAPK), which are associated with pro-inflammatory responses and cell death. The intricate regulatory mechanisms of TNFR1 signaling and its involvement in various diseases, including inflammatory disorders, infectious diseases, cancer, and metabolic syndromes, have attracted increasing scholarly attention.

Uncorrected maternal iron deficiency can lead to adverse neurodevelopmental outcomes in neonates. Therefore, the aim of this study was to assess serum ferritin concentration and prevalence of iron deficiency among pregnant women in Jiangsu, China.

This study was conducted on the basis of bionic principles to replicate birds' claw and wing movements in order to design a highly biomimetic flapping-wing aircraft capable of perching. First, a posture conversion module with a multi-motor hemispherical gear structure allows the aircraft to flap, twist, swing, and transition between its folded and unfolded states.

Methods: From January 2017 to August 2020, 7 cases (17 fingers) of degloving injury of multiple whole fingers who were treated in a two-stage fashion; an emergency first stage surgery of abdominal hypodermal pocket embedding and a second stage surgery (4 weeks later) of full thickness skin grafting, were retrospectively studied.

Cancer is the leading cause of death worldwide, accounting for nearly 10 million deaths every year. Immune checkpoint blockade approaches have changed the therapeutic landscape for many tumor types. However, current immune checkpoint inhibitors PD-1 or CTLA-4 are far from satisfactory, due to high immune-related adverse event incident (up to 60%) and the inefficiency in cases of "cold" tumor microenvironment.

The malfunction of SENPs often results in cellular dysfunction and various diseases. However, studies rarely investigated the correlation between SENP2 and lung cancer.

Using Volatile Organic Compounds (VOCs) as semiochemicals offers a sustainable approach for combating whiteflies. One such group of compounds, represented by β-ionone, has been found to possess repellent/attractant properties.

Purpose: To investigate the clinical effect of posterior perforator tibial artery flaps on repairing soft tissue defects of limbs.
Methods: From June 2012 to June 2021, 14 cases of soft tissue defects of limbs were repaired with pedicled or free flaps of posterior perforator tibial artery. Among them, there were 9 cases of pedicled flaps and 5 cases of free flaps.
Background: Gastric signet ring cell carcinoma (GSRCC) is a rare and highly malignant disease with a poor prognosis. To assess the overall survival (OS) and cancer-specific survival (CSS) of patients with GSRCC, prognostic nomograms were developed and validated using common clinical factors.
Methods: This retrospective cohort study included patients diagnosed with GSRCC between 2011 and 2018 from the National Cancer Center (n = 1453) and SEER databases (n = 2745).
Most recurrences of lung cancer (LC) occur within 3 years after surgery, but the underlying mechanism remains unclear. Here, we collect LC tissues with shorter (<3 years, recurrence group) and longer (>3 years, non-recurrence group) recurrence-free survival. By using 16S sequencing, we find that intratumor microbiome diversity is lower in the recurrence group and butyrate-producing bacteria are enriched in the recurrence group.
