RNA-binding healthy proteins contribute to modest RNA loading throughout plant extracellular vesicles.
Lewisite and many other similar arsenicals are warfare vesicants developed and weaponized for use in World Wars I and II. These chemicals, when exposed to the skin and other epithelial tissues, cause rapid severe inflammation and systemic damage. Here, we show that topically applied arsenicals in a murine model produce significant acute kidney injury (AKI), as determined by an increase in the AKI biomarkers NGAL and KIM-1. click here An increase in reactive oxygen species and ER stress proteins, such as ATF4 and CHOP, correlated with the induction of these AKI biomarkers. Also, TUNEL staining of CHOP-positive renal tubular cells suggests CHOP mediates apoptosis in these cells. A systemic inflammatory response characterized by a significant elevation in inflammatory mediators, such as IL-6, IFN-α, and COX-2, in the kidney could be the underlying cause of AKI. The mechanism of arsenical-mediated inflammation involves activation of AMPK/Nrf2 signaling pathways, which regulate heme oxygenase-1 (HO-1). Indeed, HO-1 induction with cobalt protoporphyrin (CoPP) treatment in arsenical-treated HEK293 cells afforded cytoprotection by attenuating CHOP-associated apoptosis and cytokine mRNA levels. These results demonstrate that topical exposure to arsenicals causes AKI and that HO-1 activation may serve a protective role in this setting.Okara is a byproduct of soymilk manufacturing and a rich source of protein and dietary fiber. We investigated whether okara intake improves the habit of defecation in young Japanese women (n = 52) with self-reported constipation. Subjects were categorized into placebo and test groups, who ingested soymilk (0.1 g fiber/meal) and okara (4.1 g fiber/meal) soups, respectively, every day for breakfast, for 2 weeks. Subjects' body composition, bowel movement frequency per week, and constipation assessment scale (CAS) and brief-type self-administered diet history questionnaire scores were assessed at baseline and after the intervention (Analysis 1). Further, subjects' bowel movement frequency per week and CAS scores were assessed during the 2-week follow-up (Analysis 2). There were no significant differences in age, anthropometric characteristics, nutrients intake, frequency of bowel movements per week, and total CAS scores between the placebo and test groups at baseline. After intervention, the total CAS score was significantly lower in the test group than in the placebo group. Moreover, the difference in the total CAS scores between baseline and after intervention was lower in the test group than in the placebo group, although not significant. The weekly frequency of bowel movement significantly increased for both placebo and test groups. The test group reported reduced abdominal bloating 2 weeks after the intervention, but the placebo group did not. The findings suggest that okara is effective in increasing the frequency of bowel movements and improving defecation habit in young women with self-reported constipation. PRACTICAL APPLICATION Okara is an effective food to increase the frequency of bowel movements and to improve defecation habits in young women with self-reported constipation.High-producing dairy cows are prone to oxidative stress due to their high secretion and strong metabolism, and excessive oxidative stress may cause the apoptosis of bovine mammary epithelial cells (bMECs). Myricetin (Myr) has been shown to have a wide range of pharmaceutical activities. The aim of this study was to evaluate the effect of Myr on hydrogen peroxide (H2 O2 )-induced oxidative stress and apoptosis in bMECs and to clarify the underlying mechanism. bMECs were pretreated with or without Myr and then stimulated with H2 O2 . The results showed that Myr significantly increased the total antioxidant capacity and superoxide dismutase levels and decreased the malondialdehyde (MDA) and reactive oxygen species (ROS) levels in a model of oxidative stress induced by H2 O2 in bMECs. Mechanistic studies found that Myr inhibited H2 O2 -induced oxidative stress in bMECs through the adenosine monophosphate-activated protein kinase/nuclear factor erythroid-2 related factor 2 (AMPK/NRF2) signaling pathway. Additional research found that Myr could also inhibit H2 O2 -induced apoptosis in bMECs through NRF2. These data suggest that Myr effectively alleviated oxidative stress and apoptosis in H2 O2 -induced bMECs through the activation of the AMPK/NRF2 signaling pathway.
Stroke patients should be treated as soon as possible since the benefit of reperfusion therapies is highly time-dependent. The proportion of patients eligible for reperfusion therapy is still limited, as many patients do not immediately alarm healthcare providers. The choice of healthcare system entrance influences the time of arrival in the hospital. Therefore, we assessed differences in these choices to obtain insight for strategies to reduce time delays in acute stroke patients.

Patients with suspected acute stroke admitted to the participating hospitals received a questionnaire. We assessed differences between patients who initially alarmed the general practitioner (GP) and patients who directly alarmed the emergency medical services (EMS). Additionally, we assessed regional differences and patient trajectories after medical help was sought.

We included 163 patients. Most patients alarmed the GP as primary healthcare provider (n=104; 64%), and median onset-to-door times were longer in these patientsampaigns and GP triage along with adjusting current guidelines by enabling and focusing on immediate involvement of the EMS once acute stroke is suspected.
To determine what proportion of our First Seizure referrals reflected true unprovoked first seizures or epilepsy, and to assess the long-term diagnostic accuracy of our First Seizure Clinic (FSC) by quantifying the risk of subsequent seizures in our FSC cohort.

We prospectively collected data of 200 adult patients referred to the FSC between May 2014 and December 2015. We reviewed clinical notes, electroencephalography (EEG) data and performed telephone follow-up at 28-month post-diagnosis.

Of the 200 patients referred to the FSC, 181 attended. At the initial assessment, 39 of these patients were diagnosed with epilepsy, with most of these patients (59%) found to have a history of previous seizures. Fifty patients were diagnosed with a first seizure, of which 28% were labelled as provoked seizures. Sixty nine of the patients received another diagnosis and 23 were labelled as indeterminable. At 28months follow-up, 11 (22%) of patients who received a diagnosis of first seizure subsequently received a diagnosis of epilepsy.
