Metabolic modelling as a powerful tool to identify critical components of Pneumocystis growth medium.

Establishing suitable in vitro culture conditions for microorganisms is crucial for dissecting their biology and empowering potential applications. However, a significant number of bacterial and fungal species, including Pneumocystis jirovecii, remain unculturable, hampering research efforts. P.

[3H-thymidine incorporation by interstitial myocardial cells in the rat with a single administration of the label].

The hearts were taken 1, 2, 3, 4, 5, 6, 7, 14 and 21 days after a single injection of 3H-thymidine into 20 young male Wistar rats. Label incorporation was determined on half-thin slices derived through the whole left ventricular wall. First labeled nuclei are seen on the day 1 at the level of 0.

[Myocardial connective tissue component in the critical stage of compensatory cardiac hyperfunction].

The reaction of the connective tissue component of the rat left ventricular myocardium to hypertrophy induced by ventral aorta coarctation in the subdiaphragmatic part was studied by electron microscopy with the use of morphometric analysis. The animals were sacrificed 1, 5 and 10 days after the operation. It the heart of intact animals, the relative amount of the connective tissue was equal to 10.
