Background: An objective assessment of the causes of age-related contour deformities of the soft tissues of the face and neck is very important in esthetic surgery, especially as minimally invasive techniques gain increasing popularity.
Methods: To visualize the tissues that cause age-related soft tissue changes, we performed cone-beam computed tomography (CBCT) in 37 patients who underwent facial and neck rejuvenation procedures in 2021-2022.
Results: Vertical CBCT enabled visualization of the causes and degree of tissue involvement in age-related changes in the lower third of the face and neck.
The tetradentate azamacrocycle cyclam (=1,4,8,11-tetraazacyclotetradecane) was studied profoundly for the coordination of transition metal ions, and the resulting complexes were investigated extensively for their catalytic performance in, e.g., O activation and electrocatalytic CO reduction.

Zwitterionic peptides are facile low-fouling compounds for environmental applications as they are biocompatible and fully biodegradable as their degradation products are just amino acids. Here, a set of histidine (H) and glutamic acid (E), as well as lysine (K) and glutamic acid (E) based peptide sequences with zwitterionic properties were synthesized. Both oligopeptides (KE)K and (HE)H were synthesized in d and l configurations to test their ability to resist the nonspecific adsorption of the proteins lysozyme and fibrinogen.

In this article we present problems of prognostic value of day-by-day blood pressure (BP) variability, its role in development and progression of damage of target organs in arterial hypertension, and impact on risk of cardiovascular, cerebral-vascular complications, and mortality. We also discuss methodological aspects of assessment of day-by-day BP variability. The article contains literature data on effects of antihypertensive therapy on variability of home BP, and consideration of evidence base of possibilities of the fixed amlodipine/perindopril combination for lowering day-by-day BP variability.

It emphasizes the predominant role of hypersympathicotonia in the development of the disease in this category of patients. Various mechanisms are considered, by means of which the increase of activity of the sympathetic nervous system leads to elevation of arterial pressure and potentiates early damage of target organs, first of all, damage of the heart.

Subjects And Methods: The investigation enrolled 44 patients with CHC, 9 patients with CHB, and 13 clinically healthy donors. The degree of LF in the patients was determined using transient elastography.
Aim: To evaluate the importance of lipoprotein(a) for the evaluation of cardiovascular risk in patient under 40 years of age after acute myocardial infarction or acute cerebral circulation disorder.

It was proposed the medical and diagnostic tactic in patients with acute mesenteric ischemia on basis of efficiency results of modern laboratory markers and instrumental methods. Positive laboratory D-dimer-test with computed tomography of abdominal organs or abdominal aorta and its branches CT-angiography led to diagnose thrombosis or embolism of mesenteric arteries at early terms and to reduce preoperative period. The authors presented the variant of isolated endovascular intervention in case of superior mesenteric artery thrombosis.

Direct markers of the viruses were identified using PCR and rapid culture method in 85 pregnant women divided into 3 groups: group 1 (n = 21), women with visual HPV-related clinical manifestations; group 2 (n = 48), with detectable markers of viral infections and no clinical manifestations, and group 3 consisting of pregnant women with OC without markers and clinical manifestations of viral infections (n = 16). The rate of HPV DNA detection in pregnant women was higher than that of herpesviruses (HV) CMV and/ or HSV: 37.

Examinations were performed in 3 neonatal groups: 1) premature neonates with clinical manifestations of IUI; 2) those without IUI; 3) full-term newborns. In group 1, viral (HSV and/or CMV) and bacterial infections were detectable with the same frequency.

The first group consisted of patients with necrotized parts of the intestine, while the second (control) group consisted of flowmetry data from intact intestine. Such indexes, as basal circulation, variation coefficient, blood oxygen perfusion saturation index, maximal perfusion amplitude of endothelial, neurogenic and myogenic oscillations in the intestinal volume, were showed to be valuable for the intestinal viability assessment.

Within the first 24-36 hours after the onset of the disease, wiferon and arbidol reduced the duration of fever, intoxication, and the catarrhal symptoms of the disease as a whole. The agents were shown to have an immunomodulating effect.

View Article and Find Full Text PDFA study was made of the adjuvant effect of the mouse tumor necrosis factor alpha (mTNF alpha) on DNA immunization against the herpes simplex virus type 1 (HSV1). The HSV1 gD gene (pDNAgD) served as an immunogen; mTNF alpha or its gene cloned in an eukaryotic expression vector (pDNAmTNF) were used to modulate the immune response. Double immunization with pDNAgD led to a sixfold increase in the in vitro T-cell response, a high (1:2000) titer of anti-HSV1 antibodies (including virus-neutralizing antibodies), an increase in IgG2a/IgG1 (suggesting a shift of the immune response to the Th1 type), and no change in CD4/CD8 T-cell ratio.

The qualitatively and quantitatively insufficient nutrition predetermines a deficit of macro- and micronutrient composition of daily ration and its value. Such defects of nutrition have a pronounced negative influence on the population's health and predetermine a high level of diseases of the digestive apparatus.

LPS stimulation led to the production of IL-1 beta, IL-6, and TNF-alpha, if their spontaneous production was below the threshold sensitivity of the test method, and to a statistically negligible increase of production if spontaneous production was pronounced. The concentrations of cytokines produced depended on the nature of inductors and their doses.
