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

open access: yesJournal 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

open access: yesJournal 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

Estrone and estradiol concentrations in human ovaries, testes, and adrenals during the first two years of life [PDF]

open access: yes, 1987
To determine the origin of estrogens in infant blood, we measured estrone (E1) and estradiol (E2) in the gonads of 50 girls and 64 boys who died suddenly between birth and 2 yr of age as well as in the adrenals of 18 of these infant girls and 16 of the ...

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

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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
