Lyotropic liquid crystal emulsions of LAVR-289: Influence of internal mesophase structure on cytotoxicity and in-vitro antiviral activity.

Emerging and reemerging viruses pose significant public health threats, underscoring the urgent need for new antiviral drugs. Recently, a novel family of antiviral acyclic nucleoside phosphonates (ANP) composed of a 4-(2,4-diaminopyrimidin-6-yl)oxy-but-2-enyl phosphonic acid skeleton (O-DAPy nucleobase) has shown promise. Among these, LAVR-289 stands out for its potent inhibitory effects against various DNA viruses.

Molecularly Imprinted Polymeric Nanoparticles as Drug Delivery System for Tenofovir, an Acyclic Nucleoside Phosphonate Antiviral.

A molecularly imprinted polymer of Tenofovir (1), an FDA-approved acyclic nucleoside phosphonate with antiviral activity, was synthesized using a non-covalent approach. A pre-polymerization complex was formed between (1) and DMAEMA and in-house synthetic -[(2-methacryloyloxy)ethyl] thymine, with EGDMA as a cross-linker in an MeCN/HO (9:1, 1:1) mixture as a porogen, giving an imprinting factor (IF) of 5.5 at 2.

New 19(10 → 9)abeo-euphane-type triterpenoids from Trichilia dregeana leaves and NO production inhibitory activities.

Phytochemical investigation of the EtOAc soluble fraction from leaves of Trichilia dregeana Sond. (Meliaceae) afforded naturally rare four new pentacyclic triterpenoids (1-4), together with five known pentacyclic analogs (5-8, and 11) and two steroids (9 and 10). Their structures were elucidated by extensive spectroscopic techniques such as 1D and 2D NMR and HRESIMS data analyses.

Colorectal cancer survivors' adjustment to permanent colostomy in Switzerland: A qualitative analysis.

Colostomized colorectal cancer survivors present physical, psychological, and social difficulties after treatment, which complicate their return to normal life. Nevertheless, we lack insight into their lived transition experience after treatment in Switzerland. We led nine semi-structured interviews with participants who had a colostomy for a mean of 16.

New Anatomical Concepts regarding Pubic-Related Groin Pain: A Dissection Study.

Objective: Pubis-related groin pain remains a difficult topic in orthopedic and sports medicine. A better understanding of the anatomy of the adductors and the pubic ligaments is necessary. The aim of this study is to map all the musculotendinous attachments to the pubic ligaments and to investigate in detail all the possible inter-adductor fusions.
