Removal of Cu (II) from aqueous solutions in a closed recirculating water system using cotton fabrics with nano-sized activated carbon

Региональные экологические проблемы: экологический мониторинг и менеджментWaste water occurring as a result of industrial activities is very dangerous to living organisms because of having highly toxic substances, and heavy metals. Moreover, it contains high amount of copper compounds. Various methods, such as chemical precipitation, ultrafiltration, reverse osmosis, ion exchange, biological processes and adsorption are used to eliminate and remove copper ions inside the waste water. Closed recirculating systems may be developed as an alternative to flow through systems in many industrial activities to remove heavy metals = Сточные воды, возникающие в результате промышленной деятельности, очень опасны для живых организмов из-за наличия высокотоксичных веществ и тяжелых металлов. Кроме того, они содержат большое количество соединений меди. Для устранения и удаления ионов меди внутри сточных вод используются различные методы, такие как химическое осаждение, ультрафильтрация, обратный осмос, ионный обмен, биологические процессы и адсорбция. Замкнутые рециркуляционные системы могут быть разработаны в качестве альтернативы потоку через системы во многих промышленных мероприятиях по удалению тяжелых металло

Blocking VEGF by bevacizumab attenuates VEGF-Induced vasospasm after experimental subarachnoid hemorrhage in rabbits

OBJECTIVE: Vasospasm after subarachnoid hemorrhage (SAH) plays a vital role in the development of delayed cerebral ischemia. Anti-vascular endothelial growth factor (VEGF) antibodies, like bevacizumab (BEV), may attenuate VEGF-stimulated angiogenesis, reduced vascular cell proliferation, and improve vasospasm after SAH.METHODS: Thirty-two adult male New Zealand white rabbits were randomly divided into 4 groups of 8 rabbits in each group: group 1 (control); group 2 (SAH); group 3 (SAH + vehicle); and group 4 (SAH + BEV). BEV (5 mg/kg, intraperitoneally) was administered 5 minutes after the intracisternal blood injection and continued for 72 hours once per day in the same dose for group 4. Animals were sacrificed 72 hours after SAH. Basilar artery cross-sectional areas, arterial wall thicknesses, and hippocampal degeneration scores were evaluated in all groups.RESULTS: VEGF is associated with the narrowing of the basilar artery. Treatment with BEV statistically significantly increased the cross-sectional area of the basilar artery when compared with the SAH and the vehicle groups. Basilar artery wall thicknesses in the BEV group was statistically significant smaller than in the SAH and vehicle groups. The hippocampal degeneration scores for the BEV and control groups were similar and significantly lower than those for the SAH and vehicle groups.CONCLUSIONS: Cellular proliferation and subsequent vessel wall thickening is a reason to delay cerebral ischemia and deterioration of the neurocognitive function. Intraperitoneal administration of BEV was found to attenuate cerebral vasospasm and prevent delayed cerebral ischemia and improve neurocognitive function after SAH in rabbits

Internalized Stigma in Hidradenitis Suppurativa: A Multicenter Cross-Sectional Study

Background: Hidradenitis suppurativa (HS) causes significant physical, social, and psychological burdens. Internalized stigma, acceptance of negative attitudes and stereotypes of society regarding a person's illness, has not been studied previously in HS. Objectives: The objective of this study was to investigate the internalized stigma state of HS patients and identify the factors affecting it. Methods: This multicenter, prospective, cross-sectional study included 731 patients. Internalized Stigma Scale (ISS), Hurley staging, Physician Global Assessment, Dermatology Life Quality Index (DLQI), Skindex-16, Beck Depression Inventory-II (BDI-II), and Visual Analog Scale (VAS)-pain score were used in the study. Results: The mean ISS value (57.50 ± 16.90) was comparable to the mean ISS values of studies in visible dermatological and various psychiatric diseases. A significant correlation was found between the mean values of ISS and all disease activity scores, quality of life measures, BDI-II, and VAS-pain scores. Obesity, family history, low education and income level, vulva/scrotum involvement and being actively treated are significant and independent predictive factors for high internalized stigma in multivariate analysis. Conclusions: HS patients internalize society's negative judgements, which may create a profound negative effect on access to health care. Therefore, in addition to suppressing disease activity, addressing internalized stigma is fundamental for improving health care quality
