In the present paper, we report an expedient total synthesis of triciribine, a tricyclic 7-deazapurine nucleoside and protein kinase B (AKT ) inhibitor, in 35% overall yield. Our synthesis route features a highly regioselective substitution of 1--Boc-2-methylhydrazine and a trifluoroacetic acid catalyzed one-pot transformation which combined the deprotection of the -butylcarbonyl (Boc) group and ring closure reaction together to give a tricyclic nucleobase motif.

In order to study regional faunas, one or two methods of studying Coleoptera are often used. However, a comparison of several ways of studying shows that it is more expedient to use more than one of them. Six different methods of catching Coleoptera used in studies of the biodiversity of regional faunas were compared.

Background: Mismatch between osteochondral allograft (OCA) donor and recipient sex has been shown to negatively affect outcomes. This study accounts for additional donor variables and clinically relevant outcomes.
Purpose: To evaluate whether donor sex, age, donor-recipient sex mismatch, and duration of graft storage affect clinical outcomes and failure rates after knee OCA transplantation.

Replicating psychological research has become a central concern for psychologists. Although attention has been paid to the possibility of heterogeneous populations driving replication success/failure, the heterogeneous recruitment strategies researchers use to draw samples from those populations are often overlooked. Yet recruitment strategies may bias the participants who show up and shape replication results.

Introduction: The arteriovenous fistula (AVF) is the gold standard access modality for haemodialysis, but due to patient and technical factors, it is prone to stenosis and thrombosis. The trans-radial approach offers multiple unique benefits, but its safety, efficiency and efficacy have not been rigorously studied in the context of the AVF. This study provides a case series of trans-radial AVF procedures, and a systematic review and meta-analysis of existing literature to solidify the role of the trans-radial approach in endovascular AVF surgery.
