♻️#ایبوپروفن به عنوان دارویی برای مقابله با #پیری، #زوال_عقل و #آلزایمر
#Subacute #ibuprofen #treatment rescues the #synaptic and #cognitive deficits in advanced-aged #mice
پژوهشگران کلینیک مایو 🇺🇸 و دانشگاه زیامن 🇨🇳 در پژوهشی مشترک به بررسی تاثیرات مصرف ایبوپروفن در کاهش اثرات منفی پیری بر #تخریب #مغزی و زوال عقل پرداختند.
🔬در این پژوهش که بر مدل #موش صورت گرفت، التهابات مغزی، تخریبهای #سیناپسی و #کارکردهای #شناختی موش ها پیش و پس از مصرف ایبوپروفن در سنین #جوانی، #میانسالی، #سالمندی و سالمندی زیاد مورد بررسی قرار گرفتند.
📚نتایج نشان دادند درمان #تحت-حاد با ایبوپروفن بدلیل خاصیت #ضدالتهابی موثر آن، به کاهش التهاب مغزی، بهبود #حافظه، افزایش #یادگیری، کاهش فعالیت #آستروسیتها و نیز افزایش فعالیت #هیپوکامپ منجر شده است.
Abstract
#Aging is accompanied by increased #neuroinflammation, #synaptic dysfunction, and #cognitive deficits both in #rodents and #humans, yet the onset and progression of these deficits throughout the #life #span remain unknown. These aging-related deficits affect the quality of life and present challenges to our aging #society. Here, we defined age-dependent and #progressive #impairments of synaptic and cognitive functions and showed that reducing astrocyte-related #neuroinflammation through #anti-inflammatory drug treatment in aged mice reverses these events. By comparing young (3 months), middle-aged (18 months), aged (24 months), and advanced-aged wild-type mice (30 months), we found that the levels of an #astrocytic marker, #glial #fibrillary #acidic #protein, progressively increased after 18 months of age, which preceded the decreases of the synaptic marker PSD-95. Hippocampal long-term potentiation was also suppressed in an age-dependent manner, where significant deficits were observed after 24 months of age. #Fear #conditioning tests demonstrated that #associative #memory in the #context and cued conditions was decreased starting at the ages of 18 and 30 months, respectively. When the mice were tested on hidden platform #water #maze, #spatial #learning memory was significantly impaired after 24 months of age. Importantly, subacute treatment with the anti-inflammatory drug #ibuprofen suppressed astrocyte activation and restored synaptic #plasticity and #memory #function in advanced-aged mice. These results support the critical contribution of aging-related inflammatory responses to hippocampal-dependent cognitive function and synaptic plasticity, in particular during advanced aging. Our findings provide strong evidence that suppression of #neuroinflammation could be a promising treatment strategy to preserve cognition during aging.

♻️تاثير #آموزش #همتایان بر #خودکارآمدي بيماران مبتلا به #مولتيپل #اسکلروزيس
پژوهشگران دانشگاه پزشکی همدان 🇮🇷، در پژوهشی که گزارش آن به تازگی منتشر شده است روش های نوین بهبود خودکارآمدی بیماران مبتلا به #تصلب‌چندگانه را مورد بررسی قرار دادند.
🔬در این پژوهش آزمایشی 80 داوطلب دارای MS شرکت نموده در 4 جلسه آموزشی 60 دقیقه ای را در بازه زمانی دو هفته گذراندند. خودکارآمدی ایشان پیش و پس از مداخله سنجش شد.
📚نتایج نشان دادند روشهای آموزش همتا (بیماران آموزش دیده به بیمارانی که نامطلعند) در بیماران مبتلا به اسکلروزمالتیپل برای افزایش خودکارآمدی و کنترل عوارض #جسمی و #روانی بیماری تاثیر بالایی دارد.
Abstract
Introduction: #Multiple #Sclerosis threatens independence and ability of #individuals in their #family and #society. The purpose of this study was to determine the effect of #peereducational program on multiple sclerosis patient’s #self-efficacy referred to #Farshchian hospital and the Multiple Sclerosis Association of #Hamadan City in 2015.
Methods: In this quasi-experimental study, 80 Patients with multiple sclerosis were selected with #convenience #sampling and randomly allocated to control and experimental groups. Four sessions, each 60 minutes, was performed twice a week. After one month after the last training session, self-questionnaires were completed by both experimental and control groups. Data were collected from both groups using the #Sherer #General #Self-Efficacy #Questionnaire. Data were analyzed with SPSS/16 using descriptive statistics, independent t and paired t tests.
Results: There was a significant difference between the mean scores of self-efficacy in the experimental group. The difference was not significant in the control group. There were no significant differences between the mean scores of self-efficacy of experimental and control groups before and after the intervention.
Conclusions: Peer education methods could increase the level of efficacy in patients with multiple sclerosis. This method could be used as a valuable strategy to improve the treatment and control of physical and psychological effects and increase the efficacy of the patient.
