[Physical rehabilitation for ankle joint injuries in the elderly and senile (stage 3).].

Ankle injuries are among the most common musculoskeletal injuries in the elderly. However, among the new scientific publications, both foreign and domestic, there are almost no examples and algorithms for conducting rehabilitation exercises for elderly patients, which prevents the introduction of these practices into rehabilitation measures. The purpose of our study is to evaluate the created technique of physical rehabilitation and, with a reliable result, to introduce it into the daily work of doctors of various profiles who provide assistance to patients with ankle joint injuries.

[Bile duct repair after complete intersection].

Objective: To determine the training period for imposing hepaticojejunostomy for bile duct repair.

Material And Methods: Reconstructive surgery on the bile ducts was performed in 53 patients. We analyzed the learning curves based on the incidence of anastomotic leakage after hepaticojejunostomy.

Excitation Intensity- and Size-Dependent Halide Photosegregation in CsPb(IBr) Perovskite Nanocrystals.

Although broad consensus exists that photoirradiation of mixed-halide lead perovskites leads to anion segregation, no model today fully rationalizes all aspects of this near ubiquitous phenomenon. Here, we quantitatively compare experimental, CsPb(IBr) nanocrystal (NC) terminal anion photosegregation stoichiometries and excitation intensity thresholds to a band gap-based, thermodynamic model of mixed-halide perovskite photosegregation. Mixed-halide NCs offer strict tests of theory given physical sizes, which dictate local photogenerated carrier densities.

THE DYNAMICS OF LIPID METABOLISM IN PATIENTS WITH MORBID OBESITY DEPENDING ON THE TYPE OF PERFORMED SURGERY.

The objective of the study - to determine changes in the lipidogram (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol) as a component of the metabolic syndrome in patients suffering from morbid obesity after bariatric surgery (biliopancreatic bypass surgery, laparoscopic gastric banding, laparoscopic longitudinal gastric resection). The study was based on 166 clinical cases. To achieve this goal, patients were divided into three groups according to the type of surgery underground.

Fusion Stage of HIV-1 Entry Depends on Virus-Induced Cell Surface Exposure of Phosphatidylserine.

HIV-1 entry into host cells starts with interactions between the viral envelope glycoprotein (Env) and cellular CD4 receptors and coreceptors. Previous work has suggested that efficient HIV entry also depends on intracellular signaling, but this remains controversial. Here we report that formation of the pre-fusion Env-CD4-coreceptor complexes triggers non-apoptotic cell surface exposure of the membrane lipid phosphatidylserine (PS).
