Kenyan sex worker-led organisations (SWLOs) often play a key role in the national HIV response. Accounts of these organisations frequently focus on their community-led approaches to promote sexual health. This paper addresses sensitisation, an underexplored but significant activity in the political agency of sex workers (SWs). Drawing on ethnographic fieldwork in a male SWLO in Nairobi, we examine how male SWs strategically use their position in the national HIV response to create spaces of police sensitisation. Taking police sensitisation as a manifestation of community-led advocacy and a 'politics of small steps', we examine how SWs respond to, resist and remake the political landscape of police violence. The strategy supports SWs in changing existing power relationships between themselves and the police, albeit within the confines of a criminalising legal system. The analysis of sensitisation practices supports a reimagining of SWLOs that stresses their political agency in the production of new political spaces and expands the focus on African SWLOs beyond HIV work to their political activities, which advance SWs' health, rights and social justice.Background Cognitive-behavioral therapy is an umbrella term which encompasses a wide range of distinct, yet related interventions, several of which have been shown to be efficacious in the treatment of substance use disorders. However, 12-Step programs (including Alcoholics Anonymous and Narcotics Anonymous) are traditionally the most widely known and commonly used approaches to managing alcohol and substance abuse. Objectives Therefore, this paper attempts to offer a summary of the compatibility of CBT-based approaches and 12-Step philosophy, in order to assist clinicians who work with patients with a strong adherence to 12-Step ideology. Results Specific passages from AA's Big Book, NA's Basic Text, and ancillary 12-Step literature will be highlighted where appropriate. Moreover, common roadblocks to synthesis (e.g. belief in a "higher power;" acceptance of one's "powerlessness") will also be addressed. Conclusions Clinicians who are committed to evidence-based, CBT-related practices are ultimately advised to adopt flexibility when working with patients who identify with the cultural values of 12-Step programs.The aim of this was study to examine the inter-task relationships and compare change of direction (COD) biomechanics between different angles (45°, 90°, and 180°). Twenty-seven men performed three COD tasks, whereby lower-limb and trunk kinematics and kinetics were assessed via 3D motion and ground reaction force (GRF) analysis. Key mechanical differences (p ≤ 0.025, η2 = 0.024-0.940) in velocity profiles, GRF, sagittal joint angles and moments, multiplanar knee joint moments, and technical parameters existed between CODs. The primary findings were that as COD angle increased, velocity profiles decreased (p less then 0.001, d = 1.56-8.96), ground contact times increased (p less then 0.001, d = 3.00-5.04), vertical GRF decreased (p less then 0.001, d = 0.87-3.48), and sagittal peak knee joint moments decreased (p ≤ 0.040, d = 0.62-2.73). trans-C75 Notably, the greatest peak knee internal rotation (KIRMs) and abduction moments (KAMs) and angles were observed during the 90° COD (p less then 0.001, d = 0.88-1.81), indicating that this may be the riskiest COD angle. Small to very large (r = 0.260-0.702) associations in KAMs and KIRMs were observed between tasks, indicating that evaluations at different angles are needed to develop an athlete's biomechanical injury risk profile. The results support the concept that COD biomechanics and potential surrogates of non-contact anterior cruciate ligament injury risk are "angle-dependent"; which have important implications for COD coaching, screening, and physical preparation.The spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutated continuously and newly emerging variants escape from antibody-mediated neutralization raised great concern. S protein is heavily glycosylated and the glycosylation sites are relatively conserved, thus glycans on S protein surface could be a target for the development of anti-SARS-CoV-2 strategies against variants. Here, we collected 12 plant-derived lectins with different carbohydrate specificity and evaluated their anti-SARS-CoV-2 activity against mutant strains and epidemic variants using a pseudovirus-based neutralization assay. The Lens culinaris-derived lentil lectin which specifically bind to oligomannose-type glycans and GlcNAc at the non-reducing end terminus showed most potent and broad antiviral activity against a panel of mutant strains and variants, including the artificial mutants at N-/O-linked glycosylation site, natural existed amino acid mutants, as well as the epidemic variants B.1.1.7, B.1.351, and P.1. Lentil lectin also showed antiviral activity against SARS-CoV and MERS-CoV. We found lentil lectin could block the binding of ACE2 to S trimer and inhibit SARS-CoV-2 at the early steps of infection. Using structural information and determined N-glycan profile of S trimer, taking together with the carbohydrate specificity of lentil lectin, we provide a basis for the observed broad spectrum anti-SARS-CoV-2 activity. Lentil lectin showed weak haemagglutination activity at 1 mg/mL and no cytotoxicity activity, and no weight loss was found in single injection mouse experiment. This report provides the first evidence that lentil lectin strongly inhibit infection of SARS-COV-2 variants, which should provide valuable insights for developing future anti-SARS-CoV-2 strategies.Anthracenes are aromatic compounds with flexible structure and reactivity which are of great interest to theoretical and experimental chemists. Theoretical investigations of 1,4-dihydroxy-5,8-bis[2-(2-hydroxyethylamino)ethylamino]anthracene-9,10-dione (Mitoxantrone) (DDEA) based on density functional theory, molecular dynamics and adsorption on fullerene are reported in the present research. The suitable situation for adsorption with fullerene (C60) is the cyclohex-2-ene-1,4-dione ring of DDEA. Selected quantum-molecular descriptors have been calculated to predict the most reactive sites of the DDEA molecule. Interactions of DDEA with water have been studied using MD simulations. MD simulations were also used to study solubility parameter, a significant quantity for the development of pharmaceutical formulations. The affinity of DDEA on human dihydrofolate reductase and deoxyuridine triphosphatase enzymes was investigated by MD simulation of the protein-ligand complex obtained by molecular docking study.Communicated by Ramaswamy H.
