Treatment of solitary subconjunctival cysts of filtration pad after fistulizing surgery of glaucoma

The clinical picture and cytostatic treatment of solitary subconjunctival cysts of filtration pad after fistula-forming antiglaucoma surgery are described. Twenty-seven eyes with hypertension which developed as a result of subconjunctival cysts formed in the early postoperative period in 7% of patients operated on for open-angle glaucoma. Probable mechanisms of the pathogenesis of the formation of solitary cysts are discussed and 3-staged therapy proposed, including beta-blockers, perforation of the cyst wall by YAG laser, and, in 10% of cases with rigid cysts, microsurgical revision of filtration pad.     

Refinement of technique for cosmonaut's body radiation loading estimation using of orbital station dosimetric monitoring system

Proposed is a technique for estimation of radiation loading of cosmonauts' body from the data of the space station radiation monitoring system by bringing the objective to a linear mathematical model. Resulted matrix ratios allow to work out the challenge; test calculations illustrating efficiency of the proposed technique are included.     

Cell activation mediated by glycosylphosphatidylinositol-anchored or transmembrane forms of CD14

CD14 is a glycosylphosphatidylinositol (GPI)-anchored membrane glycoprotein which functions as a receptor on myeloid cells for ligands derived from microbial pathogens such as lipopolysaccharide (LPS). We have studied the importance of the GPI tail of CD14 in signalling with the promonocytic cell line THP-1 expressing recombinant CD14 in a GPI-anchored form (THP1-wtCD14 cells) or in a transmembrane form (THP1-tmCD14). We found that, like other GPI-anchored molecules, GPI-anchored CD14 was recovered mainly from a Triton X-100-insoluble fraction, whereas transmembrane CD14 was fully soluble in Triton X-100. LPS induced cell activation of THP1-wtCD14 and of THP1-tmCD14 (protein tyrosine kinase phosphorylation, NF-kappaB activation, and cytokine production) in a very similar manner. However, anti-CD14 antibody-induced cross-linking caused a rapid calcium mobilization signal only in GPI-anchored CD14 cells. Studies with pharmacologic inhibitors of intracellular signalling events implicate phospholipase C and protein tyrosine kinases in the genesis of this antibody-induced calcium signal. Our results suggest that GPI anchoring and CD14 targeting to glycolipid-rich membrane microdomains are not required for LPS-mediated myeloid cell activation. GPI anchoring may however be important for other signalling functions, such as those events reflected by antibody cross-linking.     

Current methods for assessing mucociliary transport disorders in the diagnosis of chronic rhinosinusitis]

This paper summarises the findings of a systematic review of research on preschool vision screening. The review concludes that the provision of such screening programmes should be reconsidered, if not abandoned.     

The choice of the optimal schedules in the vaccination procedure against influenza in elderly subjects

The paper describes a clinical case of the cerebral hyperperfusion syndrome, a rare complication of carotid endarterectomy. The syndrome appeared as the generalized convulsive syndrome in the patient in the early postoperative period. In the context of clinical observation, the results of analysis of the literature are presented and the pathogenesis, diagnosis, therapy, and prevention of the cerebral hyperperfusion syndrome considered.     

Intermetallic R-phase in maraging steels of the Fe-Cr-Ni-Co-Mo system

Concentration and temperature conditions of formation of intermetallic R-phase in margining steels of the Fe-Cr-Ni-Co-Mo system are studied with the help of methods of physicochemical phase analysis and x-ray diffraction analysis. The role of chemical elements in the formation of the multicomponent R-phase is determined. A hypothesis employing the Kasper dimensional principle is suggested for multicomponent intermetallics formed in steels. __________ Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 8, pp. 44–48, August, 2006.
