Technology for melting amber chips to produce a solid block

This research is relevant, because the bulk of the mined amber comes in amber chips. Therefore, we have decided to review the current ways of melting amber chips to develop the most technologically efficient algorithm and to use it further for producing decorative items. The purpose of the work is to perfect the technology of obtaining whole-piece amber from amber chips and to explore the usability of the obtained material in decorative items and jewelry

Metabolic syndrome components and vitamin D availability relationship in late postmenopausal women

BACKGROUND: The global prevalence of vitamin D deficiency is currently a real threat due to association with major chronic non-communicable diseases. Abdominal obesity, hypertension, dyslipidemia, and hyperglycemia contribute significantly to cardiometabolic risk in late postmenopausal women.AIM: to assess the frequency of deficiency and insufficiency of 25(OH)D in late postmenopausal residents of Yekaterinburg; to establish associations of 25(OH)D serum concentration with components of metabolic syndrome and severity of menopausal symptoms.MATERIALS AND METHODS: During the period from October 2018 to March 2020 145 independently living late postmenopausal residents of Yekaterinburg were enrolled in a cross-sectional study. The following scope of data regarding each of the subjects was collected: complaints and anamnesis, anthropometry, diagnosis of metabolic syndrome, arterial hypertension and diabetes mellitus, assessment of 25 (OH)D level by the ECLIA method, LDL-C, HDL-C levels, serum TG by the enzymatic colorimetric method, as well as the evaluation of the modified menopausal index.RESULTS: Adequate serum level of 25(OH)D was detected in 20.6% patients, insufficiency and deficiency were found in 33.1 and 46.2% cases, respectively. In patients with vitamin D deficiency and insufficiency, the most frequent metabolic syndrome components were arterial hypertension (p=0.02; OR 3.5; CI 1.2–10.6) and abdominal obesity (p=0.03; OR 2.8; CI 1.1–7.2). Vitamin D deficient subjects had significantly lower serum HDL and increased TG levels (p=0.04), compared to the adequately provided 25(OH)D patients. Vitamin D levels were not associated with the severity of menopausal symptoms in late postmenopausal women. Regular daily intake of 400–2000 IU of colecalciferol contributed to higher serum 25(OH)D level.CONCLUSION: a high prevalence of vitamin D deficiency among postmenopausal women of Yekaterinburg was detected. Diagnosis and correction of vitamin D levels are necessary for timely reduction of cardiometabolic risk, primarily due to the potential pleiotropic effects of D-hormone on the renin-angiotensin-aldosterone system, carbohydrate and lipid metabolism

Social isolation impact on lafe quality in late postmenopausal women

During the CAVID-19 pandemic, older people were socially isolated for a long time. For patients over 65 years of age, communication and interaction with society plays an important role. Taking into account the presence of chronic diseases, regular consultation with specialists is necessary. This study involved 43 late postmenopausal women. The results were evaluated according to the questionnaire data before the pandemic and after 4-8 months from the beginning of self-isolation period.
