Insights into the dynamics and evolution of Rummeliibacillus stabekisii prophages in extreme environments: from Antarctic soil to spacecraft floors.

Since prophages can play a multifaceted role in bacterial evolution, this study aims to characterize the virome of Rummeliibacillus stabekisii, a bacterium isolated from different environments, including Antarctic soil and NASA spacecraft floors. From the analyses, it was found that the Antarctic strain, PP9, had the largest number of prophages, including intact ones, indicating potential benefits for survival in adverse conditions. In contrast, other strains harbored predominantly degenerate prophages, suggesting a dynamic process of gene gain and loss during evolution.

A possible case of Erdheim-Chester Disease.

To present the case of a 57-year-old male with progressive bilateral proptosis. The patient presented with bilateral proptosis and strength deficiency on the upper limbs. During hospitalization, the progression was unfavorable; proptosis progressed, causing a severe loss of vision in the left eye (from 0.

Angiotensin converting enzyme inhibitors and pulmonary hypertension.

Aim: To evaluate the efficacy of angiotensin converting enzyme inhibitors Enalapril, Fosonopril and Moexipril on mean and systolic pulmonary artery pressure.

Material And Methods: The study included Ill patients with chronic obstructive bronchopneumopathies associated with arterial hypertension and mild to moderate heart failure (NYHA I-II class). The patients were examined at baseline and after 60 days of treatment.

The use of beta blocker Nebivolol in patients with chronic obstructive pulmonary disease in association with arterial hypertension.

There were investigated 22 patients with chronic obstructive pulmonary disease in association with arterial hypertension initially and after 5 weeks of treatment with beta-blocker Nebivolol 5 mg/day. There were not detected any negative changes on bronchial permeability after treatment. Considerable improvement of endothelial function (from 7-12% to 17-35%, p < 0.
