Alzheimer's disease (AD) is marked by extracellular beta-amyloid (Aβ) plaques and intracellular Tau tangles, leading to progressive cognitive decline and neuronal dysfunction. Impaired autophagy, a process by which a cell breaks down and destroys damaged or abnormal proteins and other substances, contributes to AD progression. This study investigated Nuclear Receptor Subfamily 1 Group D Member 1 (NR1D1) as a potential therapeutic target for modulating autophagy.

The main symptoms of depression, a chronic mental illness, include sadness, low self-esteem, and a diminished sense of enjoyment in life. Many factors have been suggested to be associated with depression, one of which is low testosterone in men. The serotonin reuptake inhibitor fluoxetine (FLU), used to treat depression, has been reported to potentially have detrimental effects on spermatogenesis in rats after long-term use.

Li-ion capacitors (LICs) integrate the desirable features of lithium-ion batteries (LIBs) and supercapacitors (SCs), but the kinetic imbalance between the both electrodes leads to inferior electrochemical performance. Thus, constructing an advanced anode with outstanding rate capability and terrific redox kinetics is crucial to LICs. Herein, heterostructured ZnS/SnS2 nanosheets encapsulated into N-doped carbon microcubes (ZnS/SnS2@NC) are successfully fabricated.

Heavy metal pollution, especially arsenic toxicity, significantly impairs plant growth and development. Phenolic acids, known for their antioxidant properties and involvement in stress signaling, are gaining increased attention as plant secondary metabolites with the potential to enhance plant resistance to these stressors. This study aimed to investigate the effects of different concentrations of syringic acid (SA1, 10 μM; SA2, 250 μM; SA3, 500 μM) on growth, photosynthetic parameters, and antioxidant activity in lettuce seedlings subjected to arsenic stress (As, 100 μM).

Ovarian ischemia is a pathological condition that usually occurs due to ovarian torsion, resulting in the interruption of blood supply to the ovaries and oxygen deficiency. Silymarin (SLM) is a flavonoid complex of plant origin with pharmacological properties such as antioxidant, anti-inflammatory, and antiapoptotic effects. In this study, we investigated the effects of SLM through different pathways in rats subjected to experimental ovarian ischemia/reperfusion (I/R).

In recent years, the increasing prevalence of viral infections such as dengue (DENV) and chikungunya (CHIKV) has emphasized the vital need for new diagnostic techniques that are not only quick and inexpensive but also suitable for point-of-care and home usage. Existing diagnostic procedures, while useful, sometimes have limits in terms of speed, mobility, and price, particularly in resource-constrained environments and during epidemics. To address these issues, this study proposes a novel technique that combines 3D printing technology with electrochemical biosensors to provide a highly sensitive, user-friendly, and customizable diagnostic platform.

Thrombotic thrombocytopenic purpura (TTP) is characterized by thrombotic microangiopathy resulting from decreased activation of the von Willebrand factor-cleaving protease (ADAMTS13). TTP can cause organ damage and is often fatal if the appropriate treatment is not started immediately. Although primary immune TTP is the most common form of TTP, secondary immune etiologies, including complications from immune checkpoint inhibitors (ICIs), have also been reported.
