Interleukin-33 promotes lipolysis of adipocytes and protects male mice against obesity via activation of β-adrenergic receptor signaling.

Background: Targeting intracellular lipolysis represents a therapeutic potential for treating metabolic disorders such as obesity. Interleukin (IL)-33 has been shown to exert anti-obesity effects by reducing inflammation and restricting adipocyte hypertrophy.

Methods: In this study, male mice on a high-fat diet (HFD) were treated with IL-33 once every 2 days for 2 weeks.

Increased organic fertilizer significantly increases leaf nitrogen and phosphorus but not carbon content in a tropical tea plantation.

Carbon (C), nitrogen (N), and phosphorus (P) are essential elements for plant growth and metabolism, with their stoichiometry playing a pivotal role in ecosystem functioning. In tea plantations, fertilization strongly influences the balance of these elements. However, the effects of organic fertilizers on the leaf C, N, and P contents and their stoichiometry in tropical tea plants remain poorly understood.

Physiologically based pharmacokinetic modeling supports investigation of potential drug-drug interactions in the pre- and early post-hematopoietic stem cell transplantation stages.

Introduction: Drug-drug interactions (DDIs) are an important issue in medication safety and a potential cause of adverse drug events in the pre- and early post-hematopoietic stem cell transplantation (HSCT). This study introduced a physiologically based pharmacokinetic (PBPK) modeling platform to evaluate complex DDIs in these critical stages and to optimize dosing for personalized treatment.

Methods: PBPK models were developed using a bottom-up with middle-out approach and executed with PK-Sim software.

Genomics analysis of Vreelandella piezotolerans V23 reveals its role in D-amino acids metabolism.

D-amino acids are generally supposed to be unique metabolites existing only in bacteria. They can not only modify the bacterial cell wall and promote plant growth, but also participate in the immune regulation of mammals, which is of great significance in nature. Vreelandella piezotolerans V23, a Gram-negative and aerobic bacterium, was isolated from coastal seawater of the Yellow Sea, China.

This paper explores the effect of ultrasound (US) assisted plasma-activated water (PAW) or deionized water (DW) pretreatment combined with electrohydrodynamics (EHD) on the drying of yam. The activity characteristics of four pretreatments (plasma activated water combined with ultrasound (PAW + US), plasma activated water (PAW), deionized water combined with ultrasound (DW + US), and deionized water (DW) (control)) and their effects on drying characteristics, rehydration rate, color, reducing sugars, total phenols, infrared spectra, and volatile compositions of yam under EHD drying process were investigated. The results showed that the media pretreaded by ultrasound (US) combined with plasma-activated water (PAW) has lower media of pH (53.

Efficacy of ceftazidime-avibactam with or without polymyxin for carbapenem-resistant infections after initial treatment with polymyxin.

Although polymyxins are a suboptimal option for difficult-to-treat resistant infections, they are still preferred as the first-line treatment, especially in low- and middle-income countries. This study assesses the efficacy of ceftazidime-avibactam (CAZ-AVI) following polymyxin B failure in patients with carbapenem-resistant (CRKP) infections. We retrospectively reviewed cases of infections caused by CRKP in adults who received CAZ-AVI as salvage therapy.

Effects of Discharge Parameters on the Thawing Characteristics and Physicochemical Properties of Beef in a Dielectric Barrier Discharge (DBD) System.

Traditional thawing techniques can cause certain losses to beef quality. Due to the increasing demand for high-quality beef, there is an urgent need to research new thawing techniques. Dielectric barrier discharge (DBD), as an innovative non-thermal thawing technology, still has a lot of work to be studied.

Interleukin-33: Expression, regulation and function in adipose tissues.

Interleukin-33 (IL-33) is a pleiotropic cytokine of the IL-1 family that plays a key role in innate and adaptive immune responses and contributes to tissue homeostasis. Its role in adipose tissue function has been extensively studied, as adipose tissue serves as an important mediator of metabolic dysfunction. In adipose tissue, IL-33 is primarily produced by stromal cells.

Giant viruses as reservoirs of antibiotic resistance genes.

Nucleocytoplasmic large DNA viruses (NCLDVs; also called giant viruses), constituting the phylum Nucleocytoviricota, can infect a wide range of eukaryotes and exchange genetic material with not only their hosts but also prokaryotes and phages. A few NCLDVs were reported to encode genes conferring resistance to beta‑lactam, trimethoprim, or pyrimethamine, suggesting that they are potential vehicles for the transmission of antibiotic resistance genes (ARGs) in the biome. However, the incidence of ARGs across the phylum Nucleocytoviricota, their evolutionary characteristics, their dissemination potential, and their association with virulence factors remain unexplored.

Effect of electrohydrodynamic (EHD) drying on active ingredients, textural properties and moisture distribution of yam ().

This paper systematically investigates the changes in material properties during electrohydrodynamic (EHD) drying, the discharge characteristics of the EHD system as well as the active ingredients, textural properties (hardness, adhesiveness, etc.) and moisture distribution of yam under EHD, air drying and hot air drying were investigated. The results showed that the active particles and the ionized wind generated during the discharge process of the electrohydrodynamic drying device had a significant effect on the drying.

Hidden diversity and potential ecological function of phosphorus acquisition genes in widespread terrestrial bacteriophages.

Phosphorus (P) limitation of ecosystem processes is widespread in terrestrial habitats. While a few auxiliary metabolic genes (AMGs) in bacteriophages from aquatic habitats are reported to have the potential to enhance P-acquisition ability of their hosts, little is known about the diversity and potential ecological function of P-acquisition genes encoded by terrestrial bacteriophages. Here, we analyze 333 soil metagenomes from five terrestrial habitat types across China and identify 75 viral operational taxonomic units (vOTUs) that encode 105 P-acquisition AMGs.

IL-33 promotes pancreatic β-cell survival and insulin secretion under diabetogenic conditions through PPARγ.

Pancreatic β-cell dysfunction plays a vital role in the development of diabetes. IL-33 exerts anti-diabetic effects via its anti-inflammatory properties and has been demonstrated to increase insulin secretion in animal models. However, IL-33, as a pleiotropic cytokine, may also exert a deleterious effect on β-cells, which has not been rigorously studied.

Obesity alters immunopathology in cancers and inflammatory diseases.

Obesity is characterized by chronic low-grade inflammation and is strongly associated with multiple immunological diseases, including cancer and inflammatory diseases. Recent animal studies revealed that obesity-induced immunological changes worsen immune-driven diseases and cause resistance to immunotherapy. Here, we discuss the role of obesity in the immunopathology and treatment responses of cancers, respiratory and allergic diseases, and IL-17-mediated inflammatory diseases.

Diverse Methylmercury (MeHg) Producers and Degraders Inhabit Acid Mine Drainage Sediments, but Few Taxa Correlate with MeHg Accumulation.

Methylmercury (MeHg) is a notorious neurotoxin, and its production and degradation in the environment are mainly driven by microorganisms. A variety of microbial MeHg producers carrying the gene pair and degraders carrying the gene have been separately reported in recent studies. However, surprisingly little attention has been paid to the simultaneous investigation of the diversities of microbial MeHg producers and degraders in a given habitat, and no studies have been performed to explore to what extent these two contrasting microbial groups correlate with MeHg accumulation in the habitat of interest.
