Impairment of Assembly of the Vimentin Intermediate Filaments Leads to Suppression of Formation and Maturation of Focal Contacts and Alteration of the Type of Cellular Protrusions.

Cell migration is largely determined by the type of protrusions formed by the cell. Mesenchymal migration is accomplished by formation of lamellipodia and/or filopodia, while amoeboid migration is based on bleb formation. Changing of migrational conditions can lead to alteration in the character of cell movement.

[On studying the social economic aftermath of neirotrauma].

To implement probing medical statistic studies on neiro-trauma the cluster analysis technique was applied to classify the regions of the Russian Federation. The characteristics of social climate, demographic and economic indicators and level of medical service are considered. The eleven clusters are selected and combined into four groups.

[Functional status of musculo-venous pump of shin in various types of of operations for varicose disease].

Functional conditions of the muscular-venous pump of the shin were studied in 280 patients with varicose veins before surgery, in 164 patients in remote terms after various operations and in 54 healthy subjects on the base of guantitative plethysmographic estimation of hemodynamic parameters. At the stage of compensation all volume indices of the bloodflow were close to normal values; in the stage of decompensation the substantial increase of volume effectiveness and volume flow velocity was observed at carrying out the test for direct deep blood flow when walking. It was determined that in natural condition for venous hemodynamics the adaptation mechanisms of musculo-venous pump were not realized.

[The discovery of Culex pipiens (Diptera: Culicidae) in southern Yakutia].

The results of the investigation of the distribution of the synanthropic mosquito Culex pipiens in dwelling buildings in Nehryungri in 1992-1993 are reported. It has been recovered that this mosquito species inhabits all stone buildings and therefore it is a very important problem for city people in the region of investigation.

Formation of root hairs by the wheat Triticum Vulgare Host. Trichoblasts.

The process of root hair formation has been studied by light-, transmission-and scanning electron microscopy. In the course of root hair development a break of the outer cell wall is observed by electron microscopy. It apparently occurs after the break of the fibrillar layer.
