Key Laboratory of the Provincial Education, Department of Heilongjiang for Common Animal Disease Prevention and Treatment, College of Veterinary Medicine, Northeast Agricultural University, Harbin 150030, China. Electronic address:

Bisphenol F (BPF) is an environmental endocrine disruptor capable of crossing the placental barrier and affecting the growth and development of offspring. Despite its potential impact, systematic research about effects of BPF on the reproductive function of male offspring remains limited. In this study, pregnant female mice were exposed to BPF at doses of 40, 400, and 4000 μg/kg during gestation and lactation, respectively, to evaluate its impact on testicular damage, testosterone levels, and spermatogenesis of male offspring (F1 generation), and further explore the mechanisms using transcriptomics.

Department of Respiratory Medicine, Jinling Hospital, Nanjing Medical University, Jiangsu Province, China. Electronic address:

Circular RNA (circRNA) can sponge miRNA participate in the tumorigenesis and progression of various cancers. We substantiate for the first time that the fusion circular RNA (F-circRNA) F-circEA1 is involved in driving the echinoderm microtubule associated-protein like 4-anaplastic lymphoma kinase variant 1-positive (EML4-ALK1) lung adenocarcinoma (LUAD) progression and the expression of the parental gene EML4-ALK1, molecular mechanisms of F-circEA1 in the EML4-ALK1 LUAD remain unknown. Bioinformatics analysis showed that only miR-4673 can bind to F-circEA1 and bind to EML4-ALK1 3'-UTR to regulate the expression of EML4-ALK1.

Key Laboratory of Ministry of Education for Conservation and Utilization of Special Biological Resources in the Western, Ningxia University, Yinchuan 750021, China; School of Life Sciences, Ningxia University, Yinchuan 750021, China. Electronic address:

Objective: Polycystic ovary syndrome (PCOS) is a metabolic and endocrine disease that entails dysregulated ovulation, hyperandrogenism, and polycystic ovaries. While Wnt5a has been suggested to play key roles in follicular development and female fertility under normal conditions, its functions in the context of PCOS have yet to be established. This study was thus designed to explore the impact of Wnt5a on ovarian granulosa cell autophagy in PCOS, providing in vitro evidence in support of its role in this setting.

Background: The combination of passive immune agents (human rabies immune globulin (HRIG) and equine rabies antiserum (ERA)) with vaccines are effective measures for preventing the onset of rabies post exposure. However, ERA and HRIG have potential risks of serum allergic reactions and blood-transmitted infectious diseases. This study compared the safety, pharmacokinetics and neutralizing activity of recombinant human anti-rabies monoclonal antibody NM57 injection (rhRIG, Ormutivimab) and HRIG in combination with rabies vaccine and vaccine alone.

Rheumatoid arthritis (RA) is a chronic inflammatory disease that leads to joint deformity and ultimately disability. The metabolite of quercetin, 4-Methylcatechol (4-MC), has been acknowledged for its anti-inflammatory and antioxidant properties; however, the protective effects of 4-MC on RA and its underlying mechanisms remain incompletely elucidated. In a collagen-induced arthritis (CIA) model, we observed that 4-MC effectively mitigated joint inflammation and bone destruction in CIA mice.

Current research has found that adipose tissue is not only involved in energy metabolism, but also a highly active endocrine organ that secretes various adipokines, including adiponectin, leptin, resistin and apelin, which are involved in the regulation of physiology and pathology of tissues and organs throughout the body. With the yearly increasing incidence, obesity has become a risk factor for a variety of pathological changes, including inflammation and metabolic syndrome in various system (endocrine, circulatory, locomotor and central nervous system). Thus these symptoms lead to multi-organ dysfunctions, including the heart, liver, kidneys, brain and joints.

Carbonate radical (CO) is inevitably produced in advanced oxidation processes (AOPs) when addressing real-world aqueous environments, yet it often goes unnoticed due to its relatively lower reactivity. In this study, we emphasized the pivotal role of CO in targeting the elimination of contaminants by contrasting it with conventional reactive oxygen species (ROSs) and assessing the removal of sulfamethazine (SMT). Similar to singlet oxygen (O), CO shows a preference for electron-rich organic compounds.

Sentinel Environmental, Houston, Texas 77082, United States; Department of Civil and Environmental Engineering, and Rice Water Institute, Rice University, Houston, Texas 77005, United States.

While the use of phages in the food and biomedical sectors occurs commercially, their application in the water sector is less common and is typically demonstrated at a lower technological readiness level. This is so despite the potential that phages have to enhance the control of problematic bacteria (including pathogens) and protect infrastructure within the water sector. Fulfilling the great potential of this nascent field requires more research and development.
