Synthetic pyrethroids are a group of insecticides frequently used in public health and agriculture, and 3-PBA is a common metabolite of them. Although the liver is the primary organ responsible for metabolizing many compounds including pesticides, to the authors' knowledge there have been no studies on the direct hepatotoxic effects of 3-PBA. Therefore, this study aimed to investigate the possible hepatotoxic effects of 3-PBA on a Human Hepatoma Cell Line (HepG2) and the underlying apoptotic mechanisms. Firstly, an LC50 of 1041.242 µM was calculated for 3-PBA by using the WST-1 test with concentrations ranging between 1 µM and 10 mM.  https://www.selleckchem.com/products/baf312-siponimod.html  Following that, the HepG2 cells in the experimental group were exposed to 3 different concentrations of 3-PBA (1/5 LC50, 1/10 LC50 and 1/20 LC50) for 24 hours. The apoptotic mechanism was evaluated by using flow cytometry, and immunofluorescence assays for Caspase 3 and Bcl-2. In the flow cytometry assay, the total number of apoptotic cells increased in a dose dependent manner (p  less then  0.05). In the immunofluorescence assay, the Caspase 3 protein showed strong immunoreactivity in the experimental groups, while the reaction to the Bcl-2 protein was minimal. These results demonstrated that 3-PBA has a significant hepatotoxic effect on HepG2 cells and induces apoptosis via the regulation of Caspase-3 and Bcl-2. Furthermore, our results could further the understanding of the fundamental molecular mechanisms of 3-PBA hepatotoxicity. More studies are needed to determine the effects of long-term exposure to 3-PBA and also the molecular mechanisms underlying hepatotoxicity.Arteriovenous fistulas (AVF) are the preferred access for hemodialysis in patient with end stage renal disease. Usually, distal vessels of upper limb are preferred. There are situations in which the upper limb cannot be a site for AVFs or graft as in cases of bilateral central venous stenosis or with exhausted sites in upper limb. In these cases, lower limb AVF can be considered. Tibial-saphanous (ankle) fistula should be the preferred site over femoral AVF/graft following the principle of distal to proximal. Also, femoral AVFs are associated with more ischemic and infective complications. The present report describes successful hemodialysis in two patients with tibial-saphanous fistula a site rarely used as an option for HD access. Hemodialysis for over 1 year in one patient and 6 months in the other portrays the success of this approach.Seafood is a highly perishable food product due to microbiological, chemical, and enzymatic reactions, which are the principal causes of their rapid quality deterioration. Therefore, ever-increasing consumers' demand for high-quality seafood along with a negative perception of synthetic preservatives creates opportunities for natural preservatives such as microalgae extracts. They are potential alternatives to reduce microbial growth, increase oxidative stability, and protect the sensorial properties of seafood. Research has shown that the inclusion of microalgae extracts into the aquatic animal's diet could enhance their meat quality and increase production. This review focuses on the direct application of various microalgae extracts as seafood preservative, and their functional properties in seafood, such as antioxidant and antimicrobial activities. Besides, the potential nutritional application of microalgae extracts as an alternative in aqua-feed and their impact on seafood quality (indirect application) are also presented. The safety aspects and regulatory issues of products from microalgae are highlighted.
  Community health assessments have typically not measured health literacy at the community level. We developed the Community Health Literacy Assessment (CHLA) framework to describe county and regional health literacy activities, assets, gaps, and opportunities in Maryland.
 
  We implemented the CHLA framework in Maryland from January to August 2018. We conducted an environmental scan of Maryland's 24 counties to identify community resources, health indicators, and organizations. We targeted local health improvement coalitions and health departments for interviews in each county. We conducted qualitative interviews to understand what key community organizations throughout Maryland are doing to implement health literacy best practices and policies. We used summative content analysis to review, quantify, and interpret interview data.
 
  We conducted 57 interviews with participants from 56 organizations representing all 24 counties in Maryland. We captured data on multiple dimensions of health literacy and identifns, and ultimately lead us toward a health-literate society. We recommend that others replicate the CHLA framework to operationalize health literacy as a health indicator and include it as a community health assessment measure.
  On March 20, 2020, the Argentine Ministry of Health imposed a mandatory quarantine, which still persists.
 
  The aim of this study is to determine the variation in the prevalence of depression since the beginning of the quarantine and the evolution of risk factors, with special emphasis on the population's concerns.
 
  A longitudinal study was carried out using a digital questionnaire disseminated in social networks. The first stage (T1) was carried out from March 29 to April 12 and the second stage (T2) from May 23 to June 12, 2020. The prevalence of depression was measured using the 9-item Patients Health Questionnaire (PHQ-9).
 
  The prevalence of moderate/severe depression increased from 24.3% in T1 to 47.8% in T2 (p 0.000). Risk factors increased significantly age 18-27, female, primary and secondary school, smoking and having a poor sleep quality (p 0.000). The concerns about 'a family member getting sick' (OR 1.28; CI 1.04-1.58; p 0.016), 'changes at work' (OR 2.24; CI 1.79-2.81; p 0.000), 'running out of money' (OR 1.43; CI 1.20-1.71; p 0.000) and 'being unemployed' (OR 2.99; CI 2.55-3.52; p 0.000) were risk factors for depression. On the other hand, the concern about 'getting the virus' (OR 0.73; CI 0.61-0.87; p 0.001) was not a risk factor.
 
  The extended quarantine in Argentina is associated with an increase in the prevalence of depression; the high impact of economic and social concerns on mental health must be considered in order to avoid long-term effects.
