New drugs and stock market: a machine learning framework for predicting pharma market reaction to clinical trial announcements.

Pharmaceutical companies operate in a strictly regulated and highly risky environment in which a single slip can lead to serious financial implications. Accordingly, the announcements of clinical trial results tend to determine the future course of events, hence being closely monitored by the public. Most works focus on retrospective analysis of announcement impact on company stock prices, bypassing the consideration of the problem in the predictive paradigm.

[Ductoplasty of the post-traumatic stricture of a parotid duct].

A report on the primary application of the modern technique of plastic removal of stricture of the Stenonic duct. A clinical case of surgical intervention in the localization of stricture and salivary stone is considered. The analysis of the patient's medical history, ultrasound diagnostics, multispiral computed tomography of the maxillofacial region was carried out.

[Time course of changes in serum cytokine levels and the erysipelas clinical pattern].

The time course of changes in the values of proinflammatory tumor necrosis factor-alpha (TNF-alpha) and IL-8 and the anti-inflammatory cytokine IL-4 has been studied in 78 patients with erysipelas of different frequencies and pathomorphological forms of the disease. In erysipelas and its erythematous form, there is an increase in the levels of TNF-alpha and IL-8 in early phase of the disease, a decrease in these indices during convalescence, and a rise in the content of the cytokine IL-4, which are typical of an acute cyclic infectious process with a good outcome. In recurrent erysipelas and its most severe bullous-hemorrhagic form, there is imbalance in the production of cytokines that are suggestive of that there might be a disease recurrence.
