Abstract Starting from an anti-symplectic involution on a K3 surface, one can consider natural Lagrangian subvariety inside the moduli space of sheaves over K3. One also construct Prymian integrable system following construction Markushevich–Tikhomirov, extended by Arbarello–Saccà–Ferretti, Matteini and Sawon–Shen. In this article we address question Sawon, showing that these systems their asso...

This study was conducted to evaluate the tissue of liver, gills and kidney Rutillus caspicus exposed to concentrations of 50, 100, 150 mg of Methyl tert-butyl ether, for 7, 14, 21 days. Average water temperature of 19±1 °C, water oxygen of 7.6 ± 0.2 mg/l and zero salinity were measured. A total of 156 fishes were studied in this experiment. In the first, second and third week of the test, three...

Retinal degeneration, characterised by the progressive death of retinal neurons, is most common cause visual impairment. Oxysterols are cholesterol derivatives produced via enzymatic and/or free radical oxidation that regulate homeostasis in retina. Preclinical and clinical studies have suggested a connection between oxysterols degeneration. Here, we summarise early recent work related to retin...

The aim of this study was to investigate the correlation critical shoulder angle (CSA) in rotator cuff arthropathy patients with number damaged tendons and muscle fatty degeneration. Rotator were included study. True antero-posterior radiographs (Grashey view) used measure by first author. angles measured on radiographs. Magnetic resonance images (MRI) same assessed terms tendon involvements de...
