Sleep deprivation aggravates hepatocytes steatosis and insulin resistance by regulating exosomal microRNAs

Interdisciplinary Medicine, EarlyView.
Sleep deprivation accelerates the progression of MASLD and IR by up‐regulating the expression of miR‐3572‐5p and down‐regulating the expression of miR‐183‐5p in circulating exosomes, thereby inhibiting fatty acid β‐oxidation and disrupting insulin signaling pathways. Abstract Sleep deprivation (SD) threatens human health and increases the prevalence of

Gonadal development in the Neotropical high Andean frog Dendropsophus labialis (Amphibia: Hylidae) [PDF]

, 2016
Amphibians are one of the most threatened groups of vertebrates whose populations are declining due to many reasons including, among others, the presence of chemicals associated with human intervention and in particular, with agriculture. These chemicals

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Redox‐Associated Renal and Male Reproductive Alterations Following Dexamethasone Exposure in Male Rats: Histopathological and Spermatological Evaluations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Dexamethasone (DEX) is widely used in clinical practice, although it may also cause oxidative stress–related damage in different tissues, including the kidney and male reproductive system. This study investigated DEX‐induced renal and reproductive injury in rats and evaluated the modulatory effect of reduced glutathione on DEX‐associated redox

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

Corticosterone Under Experimental Manipulation of Nutrition and Parasite Burden in a Wild Rodent System

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Environmental pressures shape survival and life‐history dynamics partly by triggering the release of glucocorticoids, whose short‐term benefits but long‐term costs make it essential to understand what drives their levels. Here, we used an experimental manipulation of two environmental stressors—food availability and parasite burden—to directly
