BIOLOGICAL ASPECTS OF ANTIANDROGENS

Journal of Steroid Biochemistry, 1975
Flutamide (α,α,α-trifluoro-2-methyl-4'-nitro-m-propionotoluidide) at daily doses from 1–50 mg/kg reduced seminal vesicle and ventral prostate weights of intact male rats. A comparative study in castrated rats revealed that flutamide was equipotent to cyproterone acetate (CPA) as an antiandrogen.

Phytoecdysteroids: biological aspects

Phytochemistry, 2001
Phytoecdysteroids are a family of about 200 plant steroids related in structure to the invertebrate steroid hormone 20-hydroxyecdysone. Typically, they are C27, C28 or C29 compounds possessing a 14alpha-hydroxy-7-en-6-one chromophore and A/B-cis ring fusion (5beta-H).

MIGRAINE AND DEPRESSION: BIOLOGICAL ASPECTS

Clinical Neuropharmacology, 1992
There is a considerable overlap in migraine and depression incidence, and both conditions may be associated with low levels of 5-hydroxytryptamine (5-HT). During a migraine attack there is evidence for low levels of platelet 5-HT and possibly also low Vmax for 5-HT uptake; both these findings are also associated with the depressed state.

Biological aspects of chondrosarcoma: Leaps and hurdles.

Critical reviews in oncology/hematology, 2018
Chondrosarcomas are characterized by their chemo- and radioresistance leading to a therapeutic surgical approach which remains the only available treatment with a 10-year survival between 30% and 80% depending on the grade.

Biological Methylation: Selected Aspects

Annual Review of Biochemistry, 1975
Biological methylation is a broad subject that spans two principal areas of metabolism. First is a series of reactions leading to the biosynthesis of methionine (methylation of homocysteine) and then the multitude of reactions that utilize the methyl group of methionine after its activation to S-adenosylmethionine (A-Met).

Biological Aspects of Depression

Psychopathology, 1986
Several neuroendocrine studies with the clonidine-growth hormone stimulation test show endogenous depressive patients to have a reduced GH response as compared to neurotic depressives, schizophrenics and controls. The blunted GH response to clonidine seems to be a trait marker or vulnerability factor for mono- and bipolar endogenous depression.
