Growth but Not Corticosterone, Oxidative Stress, or Telomere Length Is Negatively Affected by Microplastic Exposure in a Filter‐Feeding Amphibian

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Microplastics (MPs) are of increasing global concern for species inhabiting aquatic habitats. However, the mechanisms behind animal responses to MPs still require comprehensive exploration. Amphibians are the most threatened vertebrate group with most species having a complex life cycle, commonly with an aquatic larval stage.

Endocrinology and the brain: Corticotropin-Releasing Hormone signaling [PDF]

, 2017
Corticotropin-releasing hormone (CRH) is a key player of basal and stress activated responses in the hypothalamic-pituitary-adrenal axis (HPA) and in extrahypothalamic circuits, where it functions as a neuromodulator to orchestrate humoral and behavioral

Systematic in‐hospital screening and treatment for osteoporosis in a geriatric population with hip fractures

Journal of Hospital Medicine, EarlyView.
Abstract Background Low‐trauma fractures of the hip signify osteoporosis and increase the risk of a second fracture. However, screening for secondary osteoporosis and initiating osteoporosis treatment can be challenging in a geriatric population.

Positive Association Between the Cardiometabolic Index and the Risk of Male Biochemical Androgen Deficiency in Adults

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Metabolic disorders are associated with testosterone deficiency, and the cardiometabolic index (CMI) is a recently identified metabolic indicator. The relationship between male biochemical androgen deficiency (MBAD), a precursor to testosterone deficiency, and CMI remains unclear.

The effect of aqueous extract of orchid root on the structure of ovary and hypothalamic-pituitary-gonadal hormones in polycystic ovary syndrome rat model: An experimental study

International Journal of Reproductive BioMedicine
Background: Some medical conditions, including polycystic ovarian syndrome (PCOs), may lead to infertility. In PCOs, hormonal imbalance is significant.

Variation in adrenal and thyroid hormones with life-history stage in juvenile northern elephant seals (Mirounga angustirostris) [PDF]

, 2016
Interpretation of stress responses in wildlife is inadequate due to the range of natural variation and potential confounds of individual and life-history variables. In marine mammals, endocrine response data are sparse and variable across species.

Molecular Tools to Study and Control Dopaminergic Neurotransmission With Light

Medicinal Research Reviews, EarlyView.
ABSTRACT Dopaminergic neurotransmission is involved in several important brain functions, such as motor control, learning, reward‐motivated behavior, and emotions. Dysfunctions of dopaminergic system may lead to the development of various neurological and psychiatric disorders, like Parkinson's disease, schizophrenia, depression, and addictions ...

Effects of tetramethyl bisphenol F on thyroid and growth hormone-related endocrine systems in zebrafish larvae

Ecotoxicology and Environmental Safety, 2022
Trimethyl bisphenol F (TMBPF) has recently been used as a bisphenol A substitute in polymer coatings for metal cans containing beverages or food. This study investigated whether TMBPF disrupts the endocrine system associated with thyroid hormones and ...
