Article Synopsis
  • - A systematic review and meta-analysis were conducted to determine factors affecting leptomeningeal collateral status in patients with acute ischemic stroke, analyzing 81 studies with over 17,000 participants.
  • - The analysis identified that older age, male sex, hypertension, diabetes, atrial fibrillation, cardioembolic stroke, internal carotid artery occlusion, and high admission blood glucose negatively impacted collateral status.
  • - The study suggests that hypertension and diabetes could be modified to improve outcomes in stroke patients, while older age and male sex are inherent risk factors that cannot be changed; further studies are recommended to explore treatment strategies.

Staple peptides, which have a significantly enhanced pharmacological profile, are promising therapeutic molecules due to their remarkable resistance to proteolysis and cell-penetrating properties. In this study, we designed and synthesized a series of PMI-M3-based dual-targeting MDM2/MDMX staple peptides and compared them with straight-chain peptides. The staple peptide SM3-4 screened in the study induced apoptosis of tumor cells at low μM concentrations, and the helix was significantly increased.

Article Synopsis
  • The review assessed how socioeconomic status (SES) impacts recovery outcomes for stroke patients, analyzing various indicators like education, income, and neighborhood wealth.
  • After reviewing 19 studies involving over 157,000 patients, the findings showed that lower SES is significantly linked to worse functional outcomes post-stroke.
  • The study highlights the persistent influence of social disadvantage on stroke recovery and calls for more research to explore underlying reasons for these disparities.

In eukaryotes such as humans, some non-coding single-stranded RNAs (ncRNAs) help to regulate the pre- and post-transcriptional expression of certain genes, which in turn control many important physiological processes, such as cell proliferation, distinctions, invasion, angiogenesis, and embryonic development. microRNA-126 is an important member of these miRNAs that can be directly or indirectly involved in the control of angiogenesis. Recently, numerous studies have expounded that microRNA-126 can inhibit or promote angiogenesis as well as attenuate inflammatory responses through complex molecular mechanisms.

Cerebral ischemia is a serious cerebrovascular disease with the characteristics of high morbidity, disability, and mortality. Currently, stem cell therapy has been extensively applied to a wide range of diseases, including neurological disorders, autoimmune deficits, and other diseases. Transplantation therapy with neural stem cells (NSCs) is a very promising treatment method, which not only has anti-inflammatory, antiapoptotic, promoting angiogenesis, and neurogenesis effects, but also can improve some side effects related to thrombolytic therapy.

Although inhibition of neprilysin (NEP) might be a therapeutic strategy with the potential to improve the outcome of chronic kidney disease (CKD), the versatile function of NEP with its mechanism remains obscure in kidney fibrosis. In the study, we found that NEP was abnormally increased in tubular epithelial cells of CKD patients, as well as unilateral ureteral obstruction and adenine diet-induced mice. Treatment with a United States Food and Drug Administration-approved NEP inhibitor Sacubitrilat (LBQ657) could alleviate ferroptosis, tubular injury, and delay the progression of kidney fibrosis in experimental mice.

Three kinds of excipients were selected to investigate the anti-bitterness effect on the extremely bitter characteristics of Andrographis Herba decoction, and the optimal combined anti-bitterness formula was obtained. The preparation principle of different excipients was clarified by virtual screening and experimental verification to explore the advantages of the three kinds of excipients in the combined anti-bitterness effect. Sensory evaluation showed that mPEG_(2000)-PLLA_(2000), γ-cyclodextrin(γ-CD), and aspartame all had good anti-bitterness effect, which reduced the bitterness intensity of Andrographis Herba decoction by 0.

DHA has been shown to be neuroprotective and important to neurogenesis, but its role in HG-induced brain injury and the underlying mechanisms remain unknown. To elucidate the therapeutic effect of DHA, we established a mouse model with insulin-induced hypoglycemic brain injury and an in vitro model of HT-22 cells using a sugar-free medium. DHA treatment significantly reduced neuronal death and improved HG-induced learning and memory deficits.

  • COVID-19 is a major global concern, and understanding workers' knowledge, attitudes, and practices (KAP) is vital for control efforts; a study in a large Chinese factory assessed KAP using an online survey from February 2 to 7, 2020.
  • The study collected responses from 123,768 workers, revealing generally high levels of knowledge (16.3/20), attitudes (4.5/6), and practices (5.8/6) regarding COVID-19; however, many workers mistakenly believed that gargling salt water could protect against the virus.
  • Results indicated that older workers had lower knowledge and practice levels, while better-educated workers performed better; this highlights the need for targeted
