3-[(1H-BENZO[D][1,2,3]TRIAZOL-1-YL)OXY]PROPYL 9-HYDROXY-5A,5B,8,8,11A-PENTAMETHYL-1-(PROP-1-EN-2-YL)ICOSAHYDRO-3AH-CYCLOPENTA[A]CHRYSENE-3A-CARBOXYLATE

We herein report on the synthesis of a pentacyclic triterpene functionalized through derivation of betulinic acid with hydroxybenzotriazole.The compound was fully characterized by proton (1H-NMR), carbon-13 (13C-NMR), heteronuclear single quantum coherence (HSQC) and distortionless enhancement by polarization transfer (DEPT-135 and DEPT-90) Cyclist

The risk of infection and death from COVID-19 is higher among older prisoners calm with pre-existing health conditions especially in Sub-Saharan African.Hawks L et al raise four concerns that need to be considered when developing public health and clinical responses to COVID-19 to protect prisoners.This paper applies these concerns to the Sub-Sahar

Growing concerns about the conservation of elasmobranchs have prompted a surge in research, because scientific studies that can support management actions are needed.Sawfishes are among the most threatened fishes worldwide and epitomize the challenge of conserving widely distributed, large-bodied marine fishes.We used a comparative approach to prov

Digital light processing (DLP) technology has emerged as a promising approach for fabricating high-precision microfluidic chips due to its exceptional resolution and rapid prototyping capabilities.However, UV energy penetration and resin flow dynamics during layer-by-layer printing introduce significant challenges for microchannel printing, particu

There are growing Mexican-American populations in rural areas.This editorial is a continuation of the previous column on communicating with those clients.Dr.Loretta Heuer, associate professor at the University of North Dakota, again offers suggestions to help rural nurses in caring for them.One major issue is the use of an Garlands interpreter.Ther
