Ring-tailed lemurs (Lemur catta) use olfaction to discover faraway berries.
Furthermore, overexpression of PTEN attenuated the effects of overexpressing MACC1-AS1. Conclusions The authors' results demonstrated that MACC1-AS1 promoted cell proliferation by downregulating PTEN in LUAD cells.Objective Hypertension is a disease caused by both genetic and environmental factors. In the present study, we analyzed the association of the lung cancer adenocarcinoma metastasis-associated gene 1 (MALAT1) gene rs664589 locus single nucleotide polymorphism (SNP) with the risk of essential hypertension and explored its possible mechanisms. Materials and Methods We analyzed the genotype of the MALAT1 gene rs664589 locus in 260 hypertensive patients and 260 healthy controls. The levels of plasma long-chain noncoding RNA (lncRNA) MALAT1, hsa-miR-539-3p, and hsa-miR-485-3p were determined by reverse transcription real-time quantitative PCR (qRT-PCR). The effects of MALAT1 on the expression levels of hsa-miR-539-3p, hsa-miR-485-3p, and bone morphogenetic protein receptor type 2 (BMPR2) were detected by transfection of human umbilical vein endothelial cells. Results The risk of hypertension in subjects carrying the G allele of the MALAT1 gene rs664589 locus was 1.33 times higher than the C allele carriers (95% conudies in animal models are needed to confirm this hypothesis.BACKGROUND The relationship between the medial patellofemoral ligament (MPFL) and the distal femoral physis has been reported in multiple studies. PURPOSE To determine the distance from the MPFL central origin on the distal femur to the medial distal femoral physis in skeletally immature participants. STUDY DESIGN Systematic review. METHODS A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Multiple databases were searched for studies investigating the anatomic origin of the MPFL on the distal femur and its relationship to the medial distal femoral physis in skeletally immature participants. Study methodological quality was analyzed with the Anatomical Quality Assessment tool, with studies categorized as low risk, high risk, or unclear risk of bias. Continuous variable data were reported as mean ± SD. Categorical variable data were reported as frequency with percentage. RESULTS Seven articles were analyzed (298 femurs, 53.7% male patients; mean age, 11.7 ± 3.4 years). There was low risk of bias based on the Anatomical Quality Assessment tool. The distance from the MPFL origin to the distal femoral physis ranged from 3.7 mm proximal to the physis to 10.0 mm distal to the physis in individual studies. Six of 7 studies reported that the MPFL origin on the distal femur lies distal to the medial distal femoral physis in the majority of specimens. The MPFL originated distal to the medial distal femoral physis in 92.8% of participants at a mean distance of 6.9 ± 2.4 mm. CONCLUSION The medial patellofemoral ligament originates distal to the medial distal femoral physis in the majority of cases at a mean proximal-to-distal distance of 7 mm distal to the physis. However, this is variable in the literature owing to study design and patient age and sex.Recent research on extracellular vesicles (EVs) has provided new insights into pathogenesis and potential therapeutic options for acute respiratory distress syndrome (ARDS). EVs are membrane-bound anuclear structures which carry important inter-cellular communication mechanisms, allowing targeted transfer of diverse biologic cargo including protein, mRNA and microRNA among several different cell types. In this review, we discuss the important role EVs play in both inducing and attenuating inflammatory lung injury in ARDS as well as in sepsis, the most important clinical cause of ARDS. We discuss the translational challenges which need to be overcome before EVs can also be utilized as prognostic biomarkers in patients with ARDS and sepsis. We also consider how EVs may provide a platform for novel therapeutics in ARDS.Compared to knowledge about HIV risk factors among men in the south, less is known about risk factors for women. We conducted an individually matched case-control study to identify factors associated with HIV seroconversion among women. Cases had a clinician-assisted visit (CAV) between 2011 and 2016 at an Atlanta-based public health clinic before HIV diagnosis. Controls were women who visited the clinic but remained HIV negative. Controls were matched to cases in a 21 ratio on race, age at first CAV, and date of first CAV. Conditional logistic regression was used to develop a best-fitting model for characterizing HIV risk. Of 18,281 women who were HIV negative at their first visit, 110 (0.6%) seroconverted before 2019. Of these, 80 (73%) had a CAV before HIV diagnosis. Having multiple gonorrhea episodes, a syphilis episode, a greater number of sex partners in the past 2 months, anal sex, history of drug use, history of exchanging drugs or money for sex, and heterosexual sex with >1 sex partner in the last month were individually associated with HIV seroconversion. Selleckchem ACY-775 In multivariate analyses, having a syphilis episode [odds ratio (OR) = 4.7, 95% confidence interval (CI) 1.3-16.3], anal sex (OR = 2.8, 95% CI 1.0-8.1), and injection drug or crack cocaine use (OR = 33.5, 95% CI 3.6-313.3) remained associated with HIV. Women having all three risk factors were six times more likely to seroconvert compared to women without these factors. Our results offer insights into which women in a southern HIV "hotspot" may be at greatest risk for HIV.Increasing prescription of pre-exposure prophylaxis (PrEP) is imperative to ending the HIV epidemic in the United States. The objective of this review was to identify health care provider barriers to PrEP implementation. A systematic review was conducted in February 2019 using PubMed to identify barriers to PrEP prescribing practices in the United States. Targeted search terms surrounding PrEP and providers resulted in 222 original studies, 28 of which were ultimately included in our review, with data collected between 2011 and 2018. Six themes were identified across reviewed studies (i) a lack of PrEP knowledge, (ii) the presence of the Purview Paradox, which refers to discordance in beliefs between HIV specialists and primary care providers on who should prescribe PrEP, (iii) concerns about PrEP costs, (iv) concerns about behavioral and health consequences, (v) interpersonal stigma, and (vi) concerns about patient adherence. A majority of providers were lacking knowledge regarding PrEP, resulting in discomfort in prescribing PrEP, or limited awareness and understanding of PrEP clinical guidelines.
