Genotyping as Part of Routine Clinical Care-The Outcomes for a Large Paediatric Vascular Anomaly Cohort.

We describe the phenotypic and genotypic spectrum of patients with vascular anomaly (VA) in a paediatric multi-disciplinary VA clinic. We measured the clinical utility of genotyping by comparing pre and posttest diagnosis and management. A 46-month retrospective analysis occurred for 250 patients offered genetic testing in the VA clinic.

Barnase*Barstar-guided two-step targeting approach for drug delivery to tumor cells in vivo.

For precise ligation of a targeting and cytotoxic moiety, the use of Barnase-Barstar pair as a molecular glue is proposed for the first time. Targeting was mediated through the use of a scaffold protein DARPin_9-29 specific for the human epidermal receptor 2 (HER2) antigen that is highly expressed on some types of cancer and Barnase*Barstar native bacterial proteins interacted with each other with K 10 M. The approach proposed consists of prelabeling a target tumor with hybrid protein DARPin-Barnase prior to administration of cytotoxic component-loaded liposomes that have Barstar covalently attached to their surface.

DARPin_9-29-Targeted Gold Nanorods Selectively Suppress HER2-Positive Tumor Growth in Mice.

Near-infrared phototherapy has great therapeutic potential for cancer treatment. However, for efficient application, in vivo photothermal agents should demonstrate excellent stability in blood and targeted delivery to pathological tissue. Here, we demonstrated that stable bovine serum albumin-coated gold mini nanorods conjugated to a HER2-specific designed ankyrin repeat protein, DARPin_9-29, selectively accumulate in HER2-positive xenograft tumors in mice and lead to a strong reduction in the tumor size when being illuminated with near-infrared light.

[Molecular genetic basis of sudden cardiac death in the young with cardiomyopathy of various origins].

This paper provides a review of the modern literature devoted to the problem of forensic medical interpretation of the molecular genetic research of the young who died suddenly. The authors attempted to draw a parallel between the morphological markers of different variants of cardiomyopathy as the most common disease in sudden death at a young age and the association with genetic mutations in the genes responsible for the synthesis of sarcomer proteins, desmos and membrane channels. Based on the results of the analysis, further research is proposed to improve the accuracy of forensic diagnosis in cases of young deaths.

[Morphofunctional vascular changes associated with sudden death in the young].

Diagnosis of sudden death in the young is based on the results of a set of research methods.

[Vascular pathology in the aspect of sudden death in young adults and connective tissue dysplasia: anatomical, physiological, and morphological parallels].

Vascular pathology in young adults has during the last 10 years been diagnosed more often during forensic medical examination of sudden death. Major morphological alterations are revealed in cerebral vessels, coronary vessels, and at the level of the ascending portion of the aorta. Generally, in the young age there is no stenosing atherosclerosis inducing vascular lesions and the development of complications.

[The forensic medical evaluation of traumatic and spontaneous ruptures of the organs affected by the tumours].

The present article was designed to report the results of the analysis of the cases of traumatic and spontaneous ruptures of the organs affected by the tumours based on the original observations and the literature data. It is shown that the probability of the tumour rupture depends on its histological type, localization, the size, and the distance from the capsule of the affected organ, the degree of involvement of the major blood vessels, the severity of the necrotic changes, the presence of cysts in the neoplasm, and the regimens of radio- and chemotherapy. Moreover, the rupture can be facilitated by anticoagulation therapy, intake or oral contraceptives, pregnancy, concomitant diseases, alcoholic intoxication, splenomegaly, and hypocoagulation resulting from dissemination of the neoplastic process or the metastatic lesions of the liver.

[Forensic medical characteristic of the causes behind sudden death in the young subjects].

The objective of the present study was to analyze the causes of sudden death in the general population and in the fraction of the young subjects (below 39 years of age). The results of the original retrospective study were obtained in the course of forensic medical autopsies of the subjects aged below 39 years that had been carried out during a period of 10 years. It was shown that one of the causes behind sudden death among the young subjects is cardiovascular disorders associated with the pre-existing pathological condition in the form of connective tissue dysplasia.
