The energy parameters of the liver mitochondria under the prolonged action of halothane in vitro]

Chronopharmacodynamics of long-action propranolol hydrochloride-betacap (Natko, India) was studied in 48 patients with essential hypertension stage II. Six randomized groups of patients were given a single dose of 80 mg a day: at 7, 10 a.m., 1, 4, 7 and 10 p.m. Before the treatment, 1.5, 2, 3 and 4 hours after betacap intake, 10 days after the treatment course noninvasive tests of hemodynamics were made. Maximal negative chronotropic and hypotensive effect was demonstrated at 10 p.m., 7 and 10 a.m. The hypotensive effect was hemodynamically insured either through inhibition of the heart rate alone in the intake at 1 and 4 p.m. or both inhibition of the heart rate and decreased total peripheral vascular resistance in the intake at 7 a.m. and 10 p.m., or negative inotropic action of betacap combined with negative chronotropic effect in the intake at 10 a.m. and 7 p.m. Energy consumption of the myocardium was reduced. A circadian rhythm of sensitivity to betacap is shown for total and specific peripheral resistance, rational coefficient, diastolic pressure, energy consumption with acrophase at early morning hours, left ventricular contractility at night time, systolic pressure, double production, stroke index, effective activity of the heart at day time.     

A Low-Cost Fiducial Reference Phantom for Computed Tomography

To detect the growth in lesions, it is necessary to ensure that the apparent changes in size are above the noise floor of the system. By introducing a fiducial reference, it may be possible to detect smaller changes in lesion size more reliably. We suspend three precision spheres with a precision structure built from pieces from a popular children’s building toy. We measure the distances between the centroids of the structures three ways; namely, with a high-precision mechanical method, micro computerized tomography, and medical computerized tomography. The three methods are in agreement, and also agree with the design values for the structure. It is also possible to pick a threshold so that the three spheres have their nominal volumes in the medical computerized tomography images. The use of volumetric measures allows the determination of lengths to much less than the voxel size using materials which have x-ray properties within the range of the human body. A suitable structure may be built with a very small parts cost.     

Local mechanisms of relationship between colloid-osmotic pressure and ophthalmic tone in patients with diabetes mellitus

The paper presents 5 cases of histologically verified tuberculous peritonitis followed up by the author in 1994-1996. All patients were admitted to hospital and undergone surgical intervention for emergency indications. The main symptoms were intoxication, abdominal pain and enlargement. Two typical cases are described. Tuberculous peritonitis is recommended to be included into the differential diagnostic list of acute surgical abdominal diseases.     

A site-specific endonuclease from thermophilic strain Bacillus species ZE is a ClaI isoschizomer

Strain Bacillus species ZE with a maximal yield of the ClaI isoschizomer was chosen from 12 natural thermophilic strains producing ClaI isomers. The yield is 110 times higher than that of the ClaI prototype endonuclease from Caryophanon latum L. The enzyme is sensitive to DNA dam-methylation and is highly stable under storage.     

The developmentally regulated expression of serum response factor plays a key role in the control of smooth muscle-specific genes

Do the socioeconomic characteristics of a community affect one's health? This research examines whether the socioeconomic characteristics of communities are associated with the health of community residents, over and above the socio-economic characteristics of individual residents and their families. This is the first study to examine the independent associations between community-level socio-economic status (SES) and individual-level health using a nationally representative sample of adults in the United States. Results indicate that a person's health is associated with SES characteristics of the community over and above one's own income, education, and assets. However, individual-level and family-level SES indicators are stronger predictors of health than community-level SES indicators. This research suggests that improving individual-level and family-level socioeconomic circumstances may be the more direct way to improve the health of individuals, but that understanding the community context in which a person lives may also ultimately be important to improving health.     

Infrared imaging to map power on target for a millimeter-wave source

Infrared camera images are used to calculate the power deposited on a target by a millimeter wave source. Thin carbon-impregnated sheets of Kapton are illuminated with RF energy, and then infrared images in the 3-5 /spl mu/m band provide temperature data that is used to numerically solve the heat equation and obtain absorbed power values. Techniques to determine the electrical properties of Kapton up to 94 GHz were developed.
