Atopic dermatitis (AD) disrupts a patients' quality of life and is associated with other atopic disorders, such as food allergy, allergic rhinitis, and asthma. Although topical medications are widely used, they have undesirable side effects, suggesting the need for treatments with improved efficacy and safety. In this study, we identified 3C3 as a candidate compound for AD treatment using in vitro TNFα-treated HaCaT keratinocytes and a DNFB-induced AD mouse model.

Introduction: Traumatic abdominal wall hernia (TAWH) refers to the disruption of the muscular layers of the abdominal wall following blunt traumatic injury. There is a lack of consensus in the management of TAWH, particularly when trauma laparotomy for concurrent visceral injury is required. This systematic review and meta-analysis aims to evaluate recurrence outcomes with repair technique (mesh vs.

African swine fever (ASF) causes severe disease in domestic pigs and wild boars and often results in 100% mortality. The use of attenuated strains in ASF vaccine development, based on the most recently studied ASF virus (ASFV)-Georgia (ASFV-G) strain, has proven effective. In July 2023, Vietnam became the first country in the world to have two indigenously developed ASF vaccines approved for commercial sale locally.

Background: Tuberculosis (TB)-associated hemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal condition characterized by a hyperinflammatory response. Bone marrow TB poses unique diagnostic and therapeutic challenges, often leading to delayed diagnosis and treatment. Here, we report a case of disseminated TB with bone marrow involvement, characterized by unexplained fever, pancytopenia, liver dysfunction, and associated hemophagocytosis.

Exosomes from cancer cells are versatile mediators of cell-to-cell communication, whose cargoes are dynamically loaded in response to various stress conditions. In this study, we demonstrate that under oxidative stress, cancer cells secrete exosomes that induce apoptosis in neighboring cells via the Arg/N-degron pathway. In this mechanism, Rab interacting lysosomal protein (RILP) is cleaved at Asp75 in response to oxidative stress which requires ATE1 R-transferase.

Background: This study investigates whether intrarenal reflux (pyelotubular backflow) is associated with kidney scarring in children with urinary tract infection (UTI).

Methods: We retrospectively reviewed 441 children diagnosed with UTI who underwent voiding cystourethrography (VCUG) and a technetium-99 m dimercaptosuccinic acid (DMSA) scan more than 3 months after the UTI. Intrarenal reflux was identified on VCUG.

Proteins of the NarJ subfamily from facultatively or obligately anaerobic bacteria play key roles as chaperones in folding and cofactor insertion for complex iron-sulfur molybdoenzymes (CISMs), which mediate energy production under anaerobic conditions. YcdY was identified as a NarJ subfamily member but was proposed to increase the catalytic activity of the non-CISM enzyme YcdX phosphatase, presumably by inserting a zinc cofactor into YcdX. To elucidate the structural features of YcdY required for its chaperone function, we determined the crystal structure of Enterobacter cloacae YcdY (enYcdY).

Obesity, characterized by excessive adipose tissue accumulation, is an important risk factor for the development of several chronic conditions, including cardiovascular disease, type 2 diabetes mellitus, and hypertension. The present study aimed to investigate the effects of kukoamine B (KB), a major component of the Lycii Radicis Cortex (LRC), on adipogenesis and lipid accumulation in vitro and further assess its role in obesity in vivo. For the in vitro experiments, 3T3-L1 cells and primary-cultured adipose-derived stem cells were used.

The rapid growth of the fisheries industry has resulted in numerous by-products, usually called waste, causing environmental and economic challenges. Recent advances in valorization techniques have highlighted the potential of these by-products as sources of bioactive compounds. This study aimed to investigate the antioxidant and anti-inflammatory activities of cutlassfish head peptone (CP) in lipopolysaccharide (LPS)-stimulated RAW 264.

Cardiac tissue lacks regenerative capacity, making heart transplantation the primary treatment for end-stage heart failure. Engineered cardiac tissues developed through three-dimensional bioprinting (3DBP) offer a promising alternative. However, reproducing the native structure, cellular diversity, and functionality of cardiac tissue requires advanced cardiac bioinks.

Combination chemotherapy is a promising strategy for cancer treatment, enhancing antitumor efficacy while minimizing drug resistance and mitigating the risk of single-drug overdose toxicity. Polymeric drug delivery carriers for combination chemotherapy have been developed; however, the synthetic process of amphiphilic polymers is time-consuming and laborious. The polymer entanglement-based drug encapsulation has been limited in achieving a high multidrug encapsulation efficiency because of the intrinsic preference for encapsulation of drugs upon their polarity.

Background: Airway inflammation is believed to play a crucial role in the development and progression of non-small cell lung cancer (NSCLC). However, no study has yet employed quantified imaging biomarkers to assess airway inflammation in patients with NSCLC. This study aimed to validate the hypothesis that airway inflammation is more pronounced in a large cohort of patients with NSCLC compared to controls, using airway imaging biomarkers derived from fluorine-18-fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET), as well as to explore their associations with clinical parameters.

African swine fever virus (ASFV) has substantially spread worldwide, resulting in significant economic losses in the swine industry. Despite extensive research, no ASF vaccine has surpassed the effectiveness of live attenuated vaccines. For instance, the live attenuated vaccine ASFV-G-ΔI177L/ΔLVR has demonstrated good efficacy and safety, along with prolonged persistence of ASF antibodies after vaccination.

Conjugation of substrate proteins with ubiquitin (Ub), a 76 amino acid protein, was discovered as the first major translational modification responsible for protein degradation. Ubiquitination occurs as a cascade among ubiquitin-activating enzyme (E1), ubiquitin-conjugating enzyme (E2), and ubiquitin ligases (E3) enzymes that transfer and covalently conjugate Ub to the lysine (Lys) residue and α-amino group in methionine (Met) residues of substrates. Following the initial conjugation, Ub itself then undergoes ubiquitination via its seven lysine residues (K6, K11, K27, K29, K33, K48, and K63) and N-terminal methionine (M1).

The circadian clock orchestrates behavior and physiology through the oscillation of key clock proteins like PERIOD (PER). Here, we investigate the role of ubiquitin-specific peptidase 14 (USP14) in modulating PER stability and circadian rhythms in Drosophila. We find that overexpression of USP14 in clock cells reduces PER protein levels without altering its mRNA levels whereas USP14 knockdown increases PER protein levels, suggesting that USP14 regulates PER post-translationally.

: While depression is associated with an increased risk of Alzheimer's dementia (AD), traditional AD-related biomarkers, such as amyloid-beta, have shown limited predictive value for late-life depression. Oxidative stress has emerged as a potential indicator given its shared role in both depression and dementia. This study investigated the longitudinal relationship between oxidative stress biomarkers and risk of dementia in patients with depression.

Echinochrome A (EchA), a marine-derived natural product, has shown promise in treating cardiovascular and inflammatory diseases due to its antioxidant and anti-inflammatory properties. However, its cardiac safety remains underexplored. In this study, we utilized human induced pluripotent stem cell-derived cardiac organoids (hCOs) to validate their ability to model the cardiac safety profile of EchA in a human-relevant system.

Agarases produce agar oligosaccharides with various structures exhibiting diverse physiological activities. α-Neoagaro-oligosaccharide hydrolase (α-NAOSH) specifically cleaves even-numbered neoagaro-oligosaccharides, producing 3,6-anhydro-l-galactose (l-AHG) and odd-numbered agaro-oligosaccharides (OAOSs). In this study, α-NAOSH from the agar-degrading marine bacterium JEA5 (Gaa117) was purified and characterized using an expression system to produce OAOSs and determine their bioactivity.
