The Perfect Burrow, but for What? Identifying Local Habitat Conditions Promoting the Presence of the Host and Vector Species in the Kazakh Plague System.

Introduction: The wildlife plague system in the Pre-Balkhash desert of Kazakhstan has been a subject of study for many years. Much progress has been made in generating a method of predicting outbreaks of the disease (infection by the gram negative bacterium Yersinia pestis) but existing methods are not yet accurate enough to inform public health planning. The present study aimed to identify characteristics of individual mammalian host (Rhombomys opimus) burrows related to and potentially predictive of the presence of R.

DIAGNOSTIC POSSIBILITIES OF HYDROCOLONIC ECHOGRAPHY AT CHRONIC CONSTIPATION IN CHILDREN.

Unlabelled: On the basis of 15 years' of experience the criteria of assessment of the colon was developed when performing hydrocolonic echography (HCE) and the possibilities of HCE are evaluated at chronic constipations (CC) in children. A retrospective cross research of results of HCE in 263 children with CC aged from 14 days to 17 years was conducted. HCE allowed to evaluate the position of the colon in the abdominal cavity, gave information on lengthening and lumen of the colon, structure of the intestinal wall, haustra, peculiarities of the functioning of the colon in real time.

AAV-based RNAi silencing of NADPH oxidase gp91(phox) attenuates cold-induced cardiovascular dysfunction.

Clinical observations and epidemiological surveys indicated that the prevalence of hypertension and heart diseases is increased in cold regions or during winter. Cold exposure increased NADPH oxidase gp91(phox) protein expression in heart, kidneys, and aorta in rats. The aim of this study was to investigate if RNA interference (RNAi) silencing of gp91(phox) would attenuate cold-induced hypertension and cardiovascular and renal damage.

[Microbial processes of carbon and sulfur cycles in lake Mogil'noe].

In the beginning of summer 1999, complex microbiological and biogeochemical investigations of meromictic Lake Mogil'noe (Kil'din Island, Barents Sea) were carried out. The analysis of the results shows clearly pronounced vertical zonality of the microbial processes occurring in the water column of the lake. To a depth of 8 m, the total number and activity of microorganisms was limited by the relatively low content of organic matter (OM).

[The infrared radiation dynamics of the hand under the influence of physical loading in the rehabilitation of patients with tendon injuries to the flexor muscles of the fingers and the nerves of the hand].

Infrared imaging of the hands has been conducted in kinesitherapy of patients with injured finger flexor tendons and hand nerves as compared to healthy subjects. A trend to normalization of the infrared images was recorded in the regimens without force loading, duration of the exercise schedule not less than 1 week, start of the treatment in the early postoperative period.

[Lipid peroxidation and chromosome aberrations in mice after repeated effect of helium-oxygen respiratory mixture in hyperbaric conditions].

Mice were exposed to helium-oxygen conditions (3.6 MPa, 5 sessions). Compression lasted for 6 h, isopression - 5 days, decompression - 18 h.

[Effects of prolonged hyperbarism on lipid peroxidation and structural-functional state of erythrocytes].

Prolonged helium-oxygen hyperbaric (pressure 3,6 MPa) increased diene conjugate and Schiff's base level in plasma and erythrocyte membranes of mice. In those conditions SOD and glucose 6-phosphate dehydrogenase activities were inhibited in erythrocytes. Lipid bilayer microviscosity and cholesterol content of erythrocyte membranes were increased.

[Echographic determination of duodenogastric reflux in children].

A method of echographic examination of duodenogastral reflux in children by means of multiple echographic studies of the gastroduodenal area is described. The presence of duodenogastral reflux is of a raw chicken egg (an acoustic marker) taken by the examinee from the acoustically shielded duodenum after it is filled with a 5% glucose solution, which is attained by a 3-time pressing of an echochamber by the pickup in the area of the projection of the duodenal bulb to the anterior abdominal wall.

[Use of echography in the diagnosis of gastroduodenal pathology in children].

The stomach and duodenum were examined by echography in 285 children with gastroduodenal pathology and in 206 healthy children. Evacuatory function of the stomach was assessed in accordance with the rate of evacuation from the stomach of an acoustic marker, raw egg yolk which was introduced into the stomach preliminarily filled with 5% glucose. The potentialities of echography have been demonstrated for gastritis, gastroduodenitis and peptic ulcer.

[Echography of the stomach and duodenum in children in health and disease].

The paper is concerned with the results of echography of the stomach and duodenum in 100 healthy children aged 1 month to 15 years and in 141 children with different types of gastritis, duodenitis and peptic ulcer. Echographic investigation of these hollow organs was made possible after their acoustic filling with 5% glucose solution. Echography permitted fast and reliable differentiation of the type and site of stomach and duodenal lesions, determining the presence of a gastroduodenal reflux and sizes of an ulcerative defect of the duodenal wall.

[Ultrasonic examination in tumors of the abdominal cavity and retroperitoneal space in children].

Thirty-two 4 month--5 year old children suffering liver tumors, renal cysts, Wilms' tumor and dermoid cysts of the ovary underwent ultrasonic examination. The data obtained were compared to those of histologic examination of autopsy and resected material.
