ADHD symptoms and use of anabolic androgenic steroids among male weightlifters

open access: yesScientific Reports, 2022
Use of anabolic androgenic steroids (AAS) is associated with adverse health effects. The factors that predispose to AAS use among athletes are poorly understood, but attention deficit/hyperactivity disorder (ADHD), which is known to occur among athletes ...

The Anabolic Androgenic Steroid Treatment Gap: A National Study of Substance Use Disorder Treatment

open access: yesSubstance Abuse: Research and Treatment, 2020
Background: Anabolic androgenic steroid (AAS) use is associated with serious mental and physical health problems. Evidence indicates that AAS use among people who use psychoactive substances is higher than in the general population.

Protection of HT22 neuronal cells against chemically-induced ferroptosis by catechol estrogens: protein disulfide isomerase as a mechanistic target

open access: yesScientific Reports
Ferroptosis is a form of regulated cell death, characterized by excessive iron-dependent lipid peroxidation. Biochemically, ferroptosis can be selectively induced by erastin through glutathione depletion or through inhibition of glutathione peroxidase 4 ...

Mechanism of RSL3-induced ferroptotic cell death in HT22 cells: crucial role of protein disulfide isomerase

open access: yesActa Biochimica et Biophysica Sinica
Protein disulfide isomerase (PDI) was recently shown to be an upstream mediator of erastin-induced, glutathione depletion-associated ferroptosis through its catalysis of nitric oxide synthase (NOS) dimerization

Very High Dehydroepiandrosterone Sulfate (DHEAS) in Serum of an Overweight Female Adolescent Without a Tumor

open access: yesFrontiers in Endocrinology, 2020
Introduction: An increase of serum dehydroepiandrosterone (DHEA) sulfate (DHEAS) is observed in premature adrenarche and congenital adrenal hyperplasia. Very high DHEAS levels are typical for adrenal tumors.

Effect of lumbar epidural steroid injection on neuropathic pain: a prospective observational study

open access: yesAIMS Neuroscience, 2022
Background: Low back pain (LBP) is caused by disc herniation, spinal stenosis, facet syndrome or etc. This LBP could be either nociceptive or neuropathic pain (NP). In addition, these neuropathic pain is a major contributor to chronic low back pain.

Faecal steroid measurements for the assessment of reproductive function in Japanese quail (Coturnix coturnix japonica) and kakapo (Strigops habroptilus) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Physiology at Massey University [PDF]

open access: yes, 2002
The kakapo (Strigops habroptilus) is an endangered parrot endemic to New Zealand and little is known of its reproductive physiology. Reproductive function is conventionally determined by the measurement of reproductive steroids in plasma samples. This is

Conversion of cholesterol injected into man to cholestanol via a 3-ketonic intermediate

open access: yesJournal of Lipid Research, 1967
Cholesterol-3-3H,4-14C was injected intravenously in man and its transformation to cholestanol was studied. From the 3H:14C ratios in cholestanol isolated from blood, evidence for the participation of a ketonic intermediate in the conversion was obtained.
