The self and our perception of its synchrony - Beyond internal and external cognition.

The self is the core of our mental life which connects one's inner mental life with the external perception. Since synchrony is a key feature of the biological world and its various species, what role does it play for humans? We conducted a large-scale psychological study (n = 1072) combining newly developed visual analogue scales (VAS) for the perception of synchrony and internal and external cognition complemented by several psychological questionnaires. Overall, our findings showed close connection of the perception of synchrony of the self with both internal (i.

Comparison of Compartmental and Non-Compartmental Analysis to Detect Biopharmaceutical Similarity of Intravenous Nanomaterial-Based Rifabutin Formulations.

Pharmacometric analysis is often used to quantify the differences and similarities between formulation prototypes. In the regulatory framework, it plays a significant role in the evaluation of bioequivalence. While non-compartmental analysis provides an unbiased data evaluation, mechanistic compartmental models such as the physiologically-based nanocarrier biopharmaceutics model promise improved sensitivity and resolution for the underlying causes of inequivalence.

Association of lifetime major depressive disorder with enhanced attentional sensitivity measured with P3 response in young adult twins.

Major depression is associated with alterations in the auditory P3 event-related potential (ERP). However, the persistence of these abnormalities after recovery from depressive episodes, especially in young adults, is not well known. Furthermore, the potential influence of substance use on this association is poorly understood.

TCF7L2 gene polymorphism in populations of f ive Siberian ethnic groups.

Investigation of the frequencies of functionally signif icant gene variants in the context of medical biology and gene geography is a relevant issue for studying the genetic structure of human populations. The transition from a traditional to an urbanized lifestyle leads to a higher incidence of civilizational diseases associated with metabolic disorders, including type 2 diabetes mellitus. The goal of the present paper is to analyze the frequencies of functionally signif icant gene alleles in the metabolic prof iles of indigenous Siberian peoples to identify the gene pool resilience, evaluate the susceptibility of various ethnic groups to metabolic disorders under changing environmental conditions, and predict the epidemiological situation that may occur in the near future.

[Postoperative cognitive dysfunction in elderly patients after aorta-coronary bypass under conditions of artificial blood circulation.].

In patients undergoing open myocardial revascularization under cardiopulmonary bypass (CB), one of the complications is cognitive dysfunction. The aim of the work is to study the effect of intraoperative lactic acidosis, anemia and the duration of myocardial anoxia on the change in cognitive status with the help of FAB after coronary artery bypass grafting (CABG) with CB. The negative impact of lactic acidosis on cognitive status in patients after CABG has been proven.

[Aging foot syndrome: patients screening and routing.].

The article proves that when providing medical and social care to patients of older age groups, it is advisable to pay attention not only to the patients' somatic and geriatric status, but also to perform screening of local geriatric syndromes that affect the patients' functional status, such as, in particular, aging foot syndrome. Implementation of rehabilitation treatment measures that we propose allows to maintain the patients' mobility level and consequently their general functional capability level and quality of life.

[Graft-renal bypass surgery during intraoperative dissection of renal artery in a patient with high occlusion of the aorta].

Despite advances in the development of endovascular techniques of revascularization of renal arteries, in certain clinical cases still remains the need to perform extra-anatomic renal bypass grafting. To such instances belong complicated atherosclerotic aortic lesions, technical difficulties occurring during open revascularization of the aorta and its branches, as well as aneurysms of the juxtarenal portion of the abdominal aorta. Presented herein is a clinical case concerning a patient subjected to non-standard restoration of blood flow in the right renal artery after thromboendarterectomy from the juxtarenal aorta, performed from the left-sided extraperitoneal phrenolumbotomic approach and complicated by secondary dissection of the intima in the right renal artery.

Exploring the systemic delivery of a poorly water-soluble model drug to the retina using PLGA nanoparticles.

During the drug development process, many pharmacologically active compounds are discarded because of poor water solubility, but nanoparticle-based formulations are increasingly proposed as a solution for this problem. We therefore studied the distribution of nanoparticulate carriers and the delivery of their poorly water-soluble cargo to a structure of the central nervous system, the retina, under naive and pathological conditions. The lipophilic fluorescent dye coumarin 6 (Cou6) was encapsulated into poly(lactic-co-glycolic acid) PLGA nanoparticles (NPs).
