In addition, perampanel increased Sirt3 protein expression, enhanced the activities of mitochondrial enzyme IDH2 and SOD2, and preserved BBB function in vitro. Knockdown of Sirt3 using specific siRNA (Si-Sirt3) partially reserved the effects of perampanel on neuronal injury and BBB function. Treatment with perampanel in vivo attenuated brain edema, preserved neurological function, inhibited apoptosis and microglia activation after TBI. Furthermore, perampanel increased the expression of Sirt3 and preserved BBB function after TBI. The effect of perampanel on BBB function and brain edema was abolished by knockdown of Sirt3 in vivo.
 
  Our results indicate that the noncompetitive AMPAR antagonist perampanel protects the NVU system and reduces brain damage after TBI via activating the Sirt3 cascades.

Metformin has potential effects on improving asthma airway inflammation. Regulatory T cells (Tregs) play a key role in suppressing the immunoreaction to allergens. We built an obese asthmatic mouse model by administering a high-fat diet (HFD) and ovalbumin (OVA) sensitization, with daily metformin treatment. We measured the body weight and airway inflammatory status by histological analysis, qRT-PCR, and ELISA. The percentage of Tregs was measured by flow cytometry. Obese asthmatic mice displayed more severe airway inflammation and more significant changes in inflammatory cytokines. Metformin reversed the obese situation and alleviated the airway inflammation and remodelling with increased Tregs and related transcript factors. The anti-inflammatory function of metformin may be mediated by increasing Tregs.Drug-drug interaction (DDI) is a common clinical problem that has occurred as a result of the concomitant use of multiple drugs. DDI may occur in patients under treatment with medications used for coronavirus disease 2019 (COVID-19; i.e., chloroquine, lopinavir/ritonavir, ribavirin, tocilizumab, and remdesivir) and increase the risk of serious adverse reactions such as QT-prolongation, retinopathy, increased risk of infection, and hepatotoxicity. This review focuses on summarizing DDIs for candidate medications used for COVID-19 in order to minimize the adverse reactions.
  To assess the prevalence of vitreomacular adhesion (VMA) in consecutive naïve eyes diagnosed with macular oedema (ME) secondary to retinal vein occlusion (RVO) and to longitudinally evaluate the incidence of vitreomacular interface changes over time and the influence on response to treatment.
 
  Retrospective cross-sectional analysis and longitudinal cohort study conducted at two Italian tertiary referral centres.
 
  A total of 295 eyes, treated with intravitreal ranibizumab and/or dexamethasone for ME secondary to RVO between June 2008 and May 2018, were enrolled in the study. 280 fellow eyes met the inclusion criteria and were included as control group.  https://www.selleckchem.com/products/necrosulfonamide.html  The vitreomacular interface status was evaluated by spectral domain optical coherence tomography (OCT) and graded according to the OCT-based International Classification System developed by the International Vitreomacular Traction Study (IVTS) group.
 
  At baseline, VMA was present in 130 (44.07%) RVO eyes and 142 (50.7%) control eyes (no statistically signift have an impact on the response to treatment, since it was found to result in a more intensive treatment regimen; however, it did not affect visual and anatomic outcomes. These results do not support vitrectomy or PVD induction in the prevention, nor the treatment, of RVO.
 Vitreomacular adhesion (VMA) was not found to be more prevalent in eyes with RVO compared to healthy fellow eyes, and RVO, in turn, did not result in a higher persistence of VMA over time. This suggests that VMA and RVO might be two independent retinal phenomena, with no mutual pathogenetic influence. Vitreomacular adhesion (VMA) might have an impact on the response to treatment, since it was found to result in a more intensive treatment regimen; however, it did not affect visual and anatomic outcomes. These results do not support vitrectomy or PVD induction in the prevention, nor the treatment, of RVO.The aim of this cross-sectional study was to assess the knowledge, attitudes and prevention practices (KAP) among the garment factory worker population in Bangladesh regarding a historical dengue outbreak in 2019. A total of 400 participants were selected by simple random sampling, and questionnaire-based interviews were conducted. The average score of knowledge, attitude and prevention practice was 8.33 ± 2.35, 6.32 ± 1.20 and 6.31 ± 1.50, respectively. Only 76 out of 400 participants (19%) scored above 10 (all university-educated). Participant workers reported both negative and positive attitudes regarding dengue fever (DF). Negative attitudes included an expectation of increased mortality and strained family finances from DF attacks. A significantly high number of participants (92%) believed that death from DF was inevitable. Positive attitudes included optimism about DF eradication potentials and eagerness to help and donate blood to sick relatives. Participants primarily learned about the DF prevention from mass media (244/400; 61.0%) and social media (97/400; 24.25%). The most popular prevention measures adopted were mosquito repellent incense (344/400; 86.0%) and mosquito nets (389/400; 97.25%). While most participants (358/400; 89.5%) cleaned areas where mosquitos lay eggs, only 169 out of 400 (42.25%) regularly treated with chemical sprays. Only 182 out of 400 (45.5%) reported receiving DF prevention training in the factory. Correlation between DF knowledge and education was statistically significant (r = .38, p .01, n = 398). In conclusion, gaps in KAP for dengue could be addressed by government-sponsored educational programmes that utilize the power of mass/social media for dengue prevention and control. More KAP surveillance studies are needed for other sectors of the society.
