Physical Fitness and Hormonal Profile During an 11-Week Paratroop Training Period.

Physical fitness and serum hormone concentrations have been shown to change during military training. The purpose was to examine these chronic changes in paratroopers (n = 52 male conscripts) during an 11-week training period, including acute changes induced by strenuous 5-day military field training. Hormonal profiles, body mass, maximal strength, muscle endurance, and 12-minute running test were assessed at several time points during paratrooper training.

Carbonic anhydrase isozymes II, IX, and XII in uterine tumors.

Histopathological diagnostics of gynecological malignancies continues to be challenging despite the well established criteria. For example, the morphological distinction of uterine leiomyosarcoma from certain variants of benign leiomyoma can be difficult. Herein, we investigated the expression of Carbonic anhydrase (CA) II, IX, and XII in the normal endometrium, leiomyomas, uterine sarcomas, and endometrial adenocarcinomas using immunohistochemistry.

Horseradish peroxidase-catalyzed oxidation of chlorophyll a with hydrogen peroxide: characterization of the products and mechanism of the reaction.

Horseradish peroxidase was verified to catalyze, without any phenol, the hydrogen peroxide oxidation of chlorophyll a (Chl a), solubilized with Triton X-100. The 13(2)(S) and 13(2)(R) diastereomers of 13(2)-hydroxyChl a were characterized as major oxidation products (ca. 60%) by TLC on sucrose, UV-vis, (1)H, and (13)C NMR spectra, as well as fast-atom bombardment MS.

Carbonic anhydrase IX is highly expressed in hereditary nonpolyposis colorectal cancer.

Carbonic anhydrase (CA) II, CA IX, and CA XII are expressed in various neoplasias and have been linked to tumorigenesis. We examined their expression in three different groups of colorectal cancer [i.e.

Expression of transmembrane carbonic anhydrases IX and XII in ovarian tumours.

Aims: Carbonic anhydrase (CA) isozymes IX and XII have been suggested to play a role in oncogenic processes. The aim of the present study was to investigate CA IX and XII expression in patients with ovarian tumours.

Methods And Results: A series of ovarian tumours was immunostained for CA IX and XII and the results were correlated with histopathological and clinical parameters.
