Estimation of the parameters of an imminent seismic event focus by the free surface strains

Dilatancy zones generated by an active internal source of isolated force in a heterogeneous rock mass are studied. Based on the solution of an inverse problem, the method is proposed for locating and determining the source focus parameters using the measurement data on strains of the daylight surface. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 3, pp. 25–35, May–June, 2007.     

Ia. V. Villie as a surgeon

Children during the first few years of their lives, presenting with lymphohypoplastic diathesis were studied for their blood serum content of sodium, potassium, chlorine. Relationship was found of the electrolyte balance to the processes of the lipid peroxidation, activity of the hormonal link of the antioxidant defence system.     

Hemostasis in patients operated on for abdominal hemorrhage. 3. Boundary deviations of hemostasis

The fibrinolytic process in the plasma of patients operated for abdominal haemorrhages have been investigated. The results allowed to conclude that the blockade of fibrinolysis did not effect on the course of the disease. The high level of the inhibitors and of the platelets hypoaggregation can be considered as a cause increased of the recurring gastrointestinal haemorrhages. It was demonstrated that the probability of DIC-syndrome development increased at the aggravation of the patient's state after the operation.     

Primary structure and strand specificity of BstF5I-1 DNA methyltransferase which recognizes 5''-GGATG-3''

1. Ovomucoids were purified from Muscovy duck, domestic duck and domestic goose. 2. Peptide maps of cyanogen bromide-cleaved ovomucoids from Muscovy duck and domestic duck were very similar to one another, but differed from that of goose. 3. Muscovy duck ovomucoid showed the same protease inhibitory pattern as ovomucoid from domestic duck, inhibiting trypsin in the molar ratio of 1:2 and chymotrypsin 1:1. 4. Inhibitory complexes could be detected between chymotrypsin and ovomucoid from both Muscovy and domestic duck, but not from goose, by using non-denaturing gels. 5. No complexes could be detected between DFP-inactivated chymotrypsin and any of the ovomucoids. 6. The results show that of ovomucoid from Muscovy duck more closely resembles that from domestic duck than goose.     

The dynamic follow-up of the status of patients with acute pancreatitis using a degree-of-severity scale

The authors have developed a method of dynamic control over the patients with acute pancreatitis using the lineal coefficient of gravity rating, which is based on objective parameters. This dynamic control was applied in 300 patients and made it possible to choose the most effective methods of treatment.     

DNA- and RNA-hydrolyzing antibodies from the blood of patients with various forms of viral hepatitis

Antibodies (Abs) hydrolyzing proteins, DNA, and RNA are detected in the blood of patients with various autoimmune diseases. In the present work, homogeneous preparations of IgG Abs from the blood of the healthy donors as well as patients with A, B, C, and delta types of viral hepatitis, influenza, pneumonia, tuberculosis, tonsillitis, duodenal ulcer, and some types of cancer were purified. For the first time, the fraction of IgG and its Fab fragments of patients with viral hepatitis were shown to have high DNA- and RNA-hydrolyzing activity. In case of Abs from the healthy donors and patients with other diseases, high activity of Abs was not detected. The data obtained by various methods indicate that the activity of hepatitis Abs is an intrinsic property of the immunoglobulins. The relative rates of hydrolysis of cCMP, poly(U), poly(A), poly(C), and tRNA(Phe) by hepatitis Abs were compared with those of RNase A and other RNases from human blood. Significant differences in activities of Abs and nucleases in hydrolysis of model substrates were demonstrated. Thus, catalytically active Abs can appear in the blood of patients not only with autoimmune disorders, but with viral diseases as well.     

The nephron microanatomy of the kidney in the lamprey Lampetra fluviatilis L. before and after metamorphosis

Isolated nephrons from premetamorphic lamprey larvae and adult animals were obtained using microdissection and kidney collagenase treatment methods. Significant differences in the architectonics of kidney tubules were found in larvae as compared with adults. The position of larval kidney was cranial while that in adult lampreys was caudal. The absence of nephron loop was noted in larval kidney. Distal and proximal tubules were shifted one from another in mediolateral direction. Distal tubule was significantly larger than proximal one. Mesonephric duct was located laterally near the glomus. Kidney tubules morphogenesis and nephron population number increase was observed at premetamorphic stage of larval kidney development.
