Antitumor progestins activity: Cytostatic effect and immune response.

Progestins are used to treat some hormone-sensitive tumors. This review discusses the mechanisms of progestins' effects on tumor cells, the differences in the effects of progesterone and its analogs on different tumor types, and the influence of progestins on the antitumor immune response. Progestins cause a cytostatic effect, but at the same time they can suppress the antitumor immune response, and this can promote the proliferation and metastasis of tumor cells.

[Primary Generalized Glucocorticoid Resistance: a case report].

Primary glucocorticoid resistance (OMIM 615962) is a rare endocrinologic condition caused by resistance of the human glucocorticoid receptor (hGR) to glucocorticoids (GR) and characterised by general or partial insensitivity of target organs to GK. Compensatory activation of hypothalamic-pituitary-andrenal axis results in development of a various pathological conditions caused by overstimulation of adrenal glands. Clinical spectrum may range from asymptomatic cases to severe cases of mineralocorticoid and/or androgen excess.

[The mechanisms of anti-inflammatory action of enisamium iodide].

Aim: The role of cyclooxygenases (COX-1 and/or COX-2), transcription nuclear factor NF-κB, anti-inflammatory cytokines - TGF1b, IL-4, IL-10 and pro-inflammatory cytokines IL-1, IL-6 were studied to substantiate the expediency of antiviral agent enisamium iodide (Nobazit) using to regulate key inflammatory components in acute respiratory infections, IL-8, TNF-alpha in the realization of the pharmacological activity of this drug.

Materials And Methods: Gene expression was determined by real-time RT-PCR, the concentration of interleukins was determined by ELISA, and the viability of peripheral blood mononuclear cells (PBMC) was assessed by the MTT spectrophotometric method. The chemiluminescence method was used to assess PBMC oxidant activity.

The Role of Autophagy and Apoptosis in the Combined Action of Plasma-Treated Saline, Doxorubicin, and Medroxyprogesterone Acetate on K562 Myeloid Leukaemia Cells.

The anti-cancer properties of plasma-treated solutions (PTS) and their interaction with drugs are one of the most popular topics in modern plasma medicine. Our research involved comparing the effects of four physiological saline solutions (0.9% NaCl, Ringer's solution, Hank's Balanced Salt Solution, Hank's Balanced Salt Solution with amino acids added in concentrations observed in the human blood) treated with cold atmospheric plasma and studying the combined cytotoxic effect of PTS with doxorubicin and medroxyprogesterone acetate (MPA).

The Possibility of Preventive and Therapeutic Use of Green Tea Catechins in Prostate Cancer.

Background: Prostate cancer is one of the most frequent types of cancer. Despite the existence of various treatment strategies, treatment of prostate cancer still presents serious difficulties (especially in advanced stages). Polyphenols have been extensively assessed in terms of their potential use for prostate cancer treatment and prevention.
