The most frequently detected genus in larval cultures was Haemonchus, which had been barely detected in Austria previously, followed by Trichostrongylus. Multispecific resistance of trichostrongylids in Austria seems to be on the rise and H. contortus was detected unexpectedly frequently in comparison to previous studies. There is an urgent need to develop efficient communication strategies aimed at improving the engagement of farmers and veterinarians in sustainable parasite control.The aim of this work is to study the content of phenolic compounds in P lentiscus leaves and their antioxidant effect. After extracting the phenolic compounds, fractionation by liquid/liquid partition with increasing polarity gives five extracts. Three of them (ButF, AqF and ButA) were found to have good antioxidant activity. click here Their IC50s for the inhibition of the free radical formation of DPPH are 1.76 µg/mL, 1.307 µg/ml, and 1.77 µg/mL, respectively. These values are very interesting, considering the effect of the powerful flavonoid quercetin, whose IC50 against DPPH is 1.53 µg/mL. These extracts are also active against xanthine oxidase (XO). The IC50s measured are 0.14 mg/mL, 0.186 mg/mL and 0.33 mg/mL for ButF, Aq F and ButAq F extract respectively, in comparison with allopurinol (0.44 mg/mL). A phytochemical analysis by LC/ESI-MS-MS was performed to explain the observed activities. The results show 22 peaks representing flavanols, namely catechin, d-Gallocatechin, and gallocatechin gallate. The only flavo with stronger Docking score (Gscore) and MM-GBSA dGBind.Communicated by Ramaswamy H. Sarma.The goal of this survey was to evaluate the presence and concentration as well as the co-occurrence of legislated and non-legislated mycotoxins in wheat flour samples from Brazil. A total of 200 wheat flour samples were analysed by a validated multi-mycotoxins method. DON was the mycotoxin with the highest occurrence, being present in 100% of the analysed samples and showing contamination in both years and regions (53-2905 μg kg-1). ZEN was detected in 51% ( less then LOQ-50 μg kg-1) of the samples, while T-2 (not legislated in Brazil) was detected in 13.5% ( less then LOQ-1506 μg kg-1) of all samples. Regarding co-occurrence, all samples were contaminated with two to three mycotoxins.Introduction Vertically integrating physiology into patient care has the potential to improve clinical reasoning. Clinical Physiology Grand Rounds (CPGR) is a case-based teaching method that brings together students from all years of medical school to focus on linking clinical presentations to core basic science concepts including anatomy, physiology, and pathophysiology. In this study, we describe the implementation of CPGR at two different institutions in the United States and assess student-reported outcomes.Methods We survey students who participated in CPGR at Columbia University College of Physicians & Surgeons (P&S) and Medical University of South Carolina (MUSC). Subjects were queried across three domains the benefits of attending, the impact of concept maps, and the impact of the mixed-learner environment.Results Despite differences in session leadership and the underlying medical school curricula, conference attendees reported similar benefits at the two schools included in this study. Students overwhelmingly (92.9%) reported that remembering clinical presentations was easier when they understood the underlying physiology. They also reported gaining a true understanding of concepts that were previously memorized (87.5%). Both clinical (92.5%) and preclinical students (93.1%) valued the mixed-learner environment as a component of the conference.Discussion By assuring a mixed-learner environment with near-peer interactions, using concept maps as a teaching tool, and rigorously linking clinical presentation and management to physiological concepts, we found that the key benefits of CPGR were replicable across different institutions, despite several local differences in how CPGR was implemented, led, and conducted.Lesbian women and gay men are at greater risk of post-traumatic stress disorder (PTSD) than heterosexual people, however few studies have examined PTSD in older lesbian women and gay men. This study examined predictors of having ever been diagnosed with PTSD, as well as relationships to current quality of life, among 756 lesbian women and gay men aged 60 years and older in Australia. link2 Participants were surveyed on their sociodemographic characteristics, experiences of sexual orientation discrimination over their lifetime, whether they had ever been diagnosed with PTSD, whether they were currently receiving treatment for PTSD, and their current quality of life. After adjusting for sociodemographic variables, participants who reported having a PTSD diagnosis (11.2%) had significantly more frequent experiences of discrimination over their lifetime and were significantly less likely to currently be in a relationship. Older lesbian women were significantly more likely than older gay men to report ever having had a PTSD diagnosis. Additionally, having ever been diagnosed with PTSD significantly predicted current poorer quality of life. These findings suggest that a history of PTSD among older lesbian women and gay men is linked to experiences of discrimination and other factors, with associated links to current quality of life.Olives (Olea europaea) have natural phytochemical compounds that are of great importance for their potential beneficially health effects. This study aimed to evaluate the effects of olive leaf powder (OLP) on insulin production and circulating adipokines in streptozotocin-induced diabetic rats. Forty Wistar-albino male rats, weighing 200-225 g were divided into four groups (n = 10); group I Normal healthy rats received balanced diet; group II Diabetic control rats receiving balanced diet; group III Diabetic rats receiving balanced diet + standard antidiabetic drugs (metformin, 600 mg/bw) and group four Diabetic rats received diet supplemented with 2.0% OLP. The experiment was conducted for four weeks. Our results showed that the consumption of 2.0% OLP decreased serum glucose, triglycerides (TG), total cholesterol (TC), and low-density lipoprotein (LDL) levels, whereas serum high density lipoprotein (HDL) level was increased. OLP supplementation also inhibited the atherogenic index [AI; log (TG/HDL-C) and atherogenic coefficient (AC)] levels relative to those of the untreated diabetic group. Moreover, OLP increased serum adiponectin concentration, and decreased serum leptin concentration. Liver and kidney functions were also attenuated by OLP. This finding also implies that OLP can play an important role in the treatment and delay of diabetic complications.Despite many advances in medical education, medical students continue to mostly shadow on inpatient rotations like Neurology. They seldom receive face-to-face feedback or mentorship from attending physicians. This results from not training attending physicians how to integrate medical students into clinical activities in a way that does not detract from patient rounds. The 'active feedback program' is a framework for inpatient rotations that immerses medical students in clinical activities with the attending physician providing mentorship and feedback that emphasizes brevity. Expectations are laid out early. Students pick up 2-3 patients, performing daily oral reports and focused neurological exams with immediate feedback. Feedback includes items to not only correct the treatment plan, but also improve the student's oral presentation and neurological exam skills. Students also receive formal individual feedback twice during the rotation that includes constructive criticism and specific task-oriented praise. The active feedback program awaits formal testing, but seems to result in medical students learning at an accelerated rate. Neurology residents also appear to benefit by learning from critiques of the medical students and taking on higher level responsibilities. Patient rounds move quickly, leaving time for the attending physician to keep up with other obligations. As academic Neurologists we have a duty to transfer our skills to the next generation of physicians. If proven in future studies, wide adoption of the active feedback program will allow us to finally move medical students out of the shadows and come closer to achieving this noble goal.SARS-CoV2 infection induces various degrees of infections ranging from asymptomatic to severe cases and death. Virus/host interplay contributes substantially to these outcomes. This highlights the potential roles of the host immune system in fighting virus infections. SARS-CoV-2. We highlighted the potential roles of host immune response in the modulation of the outcomes of SARS-CoV infections. The newly emerged SARS-CoV-2 mutants complicated the control and mitigation strategies measures. We are highlighting the current progress of some already deployed vaccines worldwide as well as those still in the pipelines. Recent studies from the large ongoing global vaccination campaign are showing promising results in reducing the hospitality rates as well as the number of severe SARS-CoV-2 infected patients. link3 Careful monitoring of the genetic changes of the virus should be practiced. This is to prepare some highly sensitive diagnostic assays as well as to prepare some homologous vaccines matching the circulating strains in the future.The World Health Organization (WHO) proposed a set of criteria to be considered for the prioritization of COVID-19 candidate vaccines for further development of phase II/III clinical trials, thinking in a target audience that includes vaccine scientists, product developers, manufacturers, regulators, and funding agencies. In this paper, a knowledge-based or rational strategy is employed to perform a prioritization matrix of approved COVID-19 vaccines BBIBP-CorV, JANSSEN, CORONAVAC, SPUTNIK V, MODERNA, PFIZER, and VAXZEVRIA, based on those proposed criteria by WHO, related to safety, efficacy, stability, implementation, and availability. We found that JANSSEN vaccine is the one with the highest score in the present study, but our analysis suggests that the WHO criteria could be more useful if they are considered separately, taking into account the social, demographic and economic characteristics of each country.
Hyperpigmentation disorders are commonly encountered in dermatology clinics. The use of prescription-grade and over-the-counter topical lightening agents has increased in popularity, leading to a substantial growth of research over the past decade.
We seek to review clinical studies evaluating the use of different Rx-grade and OTC ingredients in treating hyperpigmentation.
A comprehensive search on PubMed was conducted to identify patient-based evidence on the most common ingredients used as topical lightening agents arbutin, ascorbic acid, cysteamine, hydroquinone, kojic acid, niacinamide, retinoids, and triple-combination therapy. The topicals were classified as either prescription-grade or over-the-counter.
Varying levels of evidence support the use of topicals in treating hyperpigmentation. There were more clinical trials examining Rx-grade products than OTC products. Mild but tolerated side effects are noted in many of these agents.
Careful monitoring and adjustment of doses will be needed to maximize skin lightening benefits and minimize side effects.
