The dynamics of potential distribution of cardiac electric field on the body surface was studied in renovascular hypertensive rats (Goldblatt type) during the ventricular activity. Three inversions of the mutual location of positive and negative areas of the cardiac electric field on the body surface were found in normotensive and hypertensive rats during the QRS-T period. Left ventricular hypertrophy of the heart in rats caused by renovascular hypertension results in changes of temporal and amplitude characteristics of the body surface potential distribution during the initial and terminal ventricular activity. The shifting trajectory of the positive and negative areas and their extremal ranges on the body surface does not change during the ventricular activity in rats with left ventricular hypertrophy of the heart as compared to the initial normotensive state.

Rejection of the concept of hemiurid genus Pulmovermis (Digenea: Hemiuridae) and other taxonomic propositions: new morphological and molecular data regarding Lecithochirium cyanovitellosum (Coil and Kuntz, 1960) Urabe and Sokolov, comb. nov. (formerly Pulmovermis cyanovitellosus).

Pulmovermis cyanovitellosus Coil and Kuntz, 1960 is a species of hemiurid trematode that localizes in the lung of sea snakes, an unusual trait for this group of parasites. Recent molecular phylogenetic studies based on 28S rRNA gene sequences have shown that this species is closely related to members of the genus Lecithochirium Lühe, 1901. This finding is unexpected given that Pulmovermis Coil and Kuntz, 1960 and Lecithochirium are currently classified in different subfamilies of Hemiuridae (Pulmoverminae Sandars, 1961 vs.

It is well-known among swimmers and coaches that the swimming speed of the underwater dolphin kick (UDK) is higher than that of the underwater flutter kick (UFK). This study aimed to clarify the differences in swimming performance between the two kicking styles in terms of kinematics, kinetics and muscle activity. Eight male swimmers performed UDK and UFK in a water flume at same effort levels.

The treatment for osteoarthritis (OA) often requires total joint arthroplasty (TJA) when less invasive approaches fail. The annual incidence of TJA is rising. Metal-on-metal (MoM) hip and knee implants were widely used for TJA in the past, but complications have led to their decline.

Evaporation or freezing of water-rich fluids with dilute concentrations of dissolved salts can produce brines, as observed in closed basins on Earth and detected by remote sensing on icy bodies in the outer Solar System. The mineralogical evolution of these brines is well understood in regard to terrestrial environments, but poorly constrained for extraterrestrial systems owing to a lack of direct sampling. Here we report the occurrence of salt minerals in samples of the asteroid (101955) Bennu returned by the OSIRIS-REx mission.
