Changes in the Level of DNA Fragmentation in Sperm Cells detected by Acridine Orange Test in Men with Sub/infertility Treated with Nutritional Supplement PAPA.

Background: When diagnosing and treating male infertility it is important to determine whether there are defects in the maturation process of sperm nuclei. Using nutritional supplements can improve the morphological and physiological condition of the spermatozoa. In recent years there has been an increase in the usage of supplements with different compositions which strives to determine the best combination and avoid side effects.

Differential effects of statins on endogenous H2S formation in perivascular adipose tissue.

Hydrogen sulfide (H(2)S) is a new gasotransmitter synthesized enzymatically from l-cysteine in cytosol and is oxidized in mitochondria. In the cardiovascular system, H(2)S regulates vascular tone, inhibits atherogenesis, and protects against myocardial ischemia-reperfusion injury. We examined the effect of statins on vascular H(2)S production.

Early results of the use of ProRoot MT and Titan cement for furcation perforation repair--a comparative experimental study.

Unlabelled: The aim of the present experimental study was to follow up the connective tissue response after using ProRoot MTA and Titan cement to repair furcation perforations in dogs.

Material And Methods: Four animals aged 12 to 18 months were used in the study. Perforation defects were created in the center of the pulp chamber of mandibular premolars P2, P3 and P4, right and left.
