An immunochemical sol-gel-based immunoaffinity purification (IAP) method for purification and detection of the progestin drug medroxyprogesterone acetate (MPA) was developed. A polyclonal antibody (Ab) for MPA was generated, and two competitive (indirect and direct) sensitive enzyme-linked immunosorbent assays (ELISAs) for its detection were developed and implemented to determine the recovery a...

Abstract One challenge in the development of new drug formulations is overcoming their low solubility relevant aqueous media. Reducing particle size powders to a few hundred nanometers well‐known method that leads an increase due elevated total surface area. However, state‐of‐the‐art comminution techniques like cryo‐milling suffer from degradation and contamination drugs, particularly when sub‐...

Biotransformation of melengestrol acetate (MGA, 17α-acetoxy-6-methyl-16-methylenepregna-4,6-diene-3,20-dione) (1) was investigated for the first time by using fungal cultures. Incubation of compound 1 with Cunninghamella blakesleeana yielded a new major metabolite, 17α-acetoxy-11β-hydroxy-6-methyl-16-methylenepregna-4,6-diene-3,20-dione (2). The metabolite 2 was purified by using HPLC, followed...

: Primary carcinoma of the fallopian tube is a rare, but fatal gynecologic cancer. The preoperative diagnosis this challenging due to absence specific symptoms and signs, in most patients, it an intraoperative finding. A 55-year-old patient (G3Ab1P2) was referred urogynecology clinic our hospital with chief complaints heavy, prolonged menstrual bleeding persistently abnormal yellow discharge, w...

BACKGROUND Cachexia is a complex metabolic syndrome associated with cancer. One of the features of cachexia is the loss of muscle mass, characterized by an imbalance between protein synthesis and protein degradation. Muscle atrophy is caused by the hyperactivation of some of the main cellular catabolic pathways, including autophagy. Cachexia also affects the cardiac muscle. As a consequence of ...

Angus x crossbred heifers (270 per trial) were used in an experiment conducted over one 105-d summer and one 104-d winter feeding period. Treatments were identical for each trial and included: 1) control, 2) estrogenic implant (E), 3) trenbolone acetate implant (TBA), 4) E + TBA (ET), 5) melengestrol acetate (MGA) in the feed, and 6) ET + MGA (ETM). Each treatment was replicated in five pens, w...

Anorexia and malnutrition are common complications and powerful predictors of morbidity and mortality in peritoneal dialysis (PD) patients. Megestrol acetate (MA) is a progestogen that has been demonstrated to increase appetite and weight in patients with cancer or acquired immunodeficiency syndrome. To determine whether MA might benefit PD patients, we treated 32 patients with 160 mg MA daily....

Body wasting in the context of chronic illness is associated with reduced quality of life and impaired survival. Recent clinical trials have investigated different approaches to improve patients' skeletal muscle mass and strength, exercise capacity, and survival in the context of cachexia and body wasting, many of them in patients with cancer. The aim of this article was to summarize clinical t...
