Highly Diastereoselective Synthesis of 2,3-Dihydropyrroles via Formal [4 + 1] Annulation Reaction of α,β-Unsaturated Imines and Generated Pyridinium Ylide.

We report a cascade approach for the synthesis of 2,3-dihydropyrroles derivatives via a formal [4 + 1] annulation reaction of α,β-unsaturated imines with generated pyridinium ylides. Importantly, this protocol is compatible with diverse substituted imines as well as pyridinium ylides, constructing 2,3-dihydropyrroles with excellent yield and selectivity. Thereafter, the Merrifield resin-supported pyridinium ylide as a potential C1 synthon was also employed in our strategy and reused several times, resulting in products with excellent yield and diastereoselectivity.

A 16-week progressive exercise training intervention in treatment-naïve chronic lymphocytic leukaemia: a randomised-controlled pilot study.

Background: Chronic lymphocytic leukaemia (CLL) typically presents with asymptomatic, early-stage disease that is monitored until disease progression ('treatment-naïve' CLL). The objective of this pilot study was to assess the feasibility and preliminary safety of an exercise program in treatment-naïve CLL. We also sought to preliminarily assess the impact of the exercise program on disease activity, as it has been proposed that exercise training may reduce disease outgrowth in treatment-naïve CLL.

GRAViTy-V2: a grounded viral taxonomy application.

Taxonomic classification of viruses is essential for understanding their evolution. Genomic classification of viruses at higher taxonomic ranks, such as order or phylum, is typically based on alignment and comparison of amino acid sequence motifs in conserved genes. Classification at lower taxonomic ranks, such as genus or species, is usually based on nucleotide sequence identities between genomic sequences.

Role for the PIP-binding protein myristoylated alanine-rich C-kinase substrate in vascular tissue: A novel therapeutic target for cardiovascular disease.

In vascular smooth muscle cells (VSMCs) and vascular endothelial cells (VECs), phosphatidylinositol 4,5-bisphosphate (PIP) acts as a substrate for phospholipase C (PLC)- and phosphoinositol 3-kinase (PI3K)-mediated signaling pathways and an unmodified ligand at ion channels and other macromolecules, which are key processes in the regulation of cell physiological and pathological phenotypes. It is envisaged that these distinct roles of PIP are achieved by PIP-binding proteins, which act as PIP buffers to produce discrete pools of PIP that permits targeted release within the cell. This review discusses evidence for the expression, cell distribution, and role of myristoylated alanine-rich C-kinase substrate (MARCKS), a PIP-binding protein, in cellular signaling and function of VSMCs.

Structural and optical studies of fluoride ion binding using N-heteroaromatic ligands.

8-Hydroxyquinoline and imidazole, two important N-heteroaromatic systems, have a strong affinity towards various anions their acidic OH or NH protons. Three receptor ligands, 5-(1-benzo[]imidazol-2-yl)quinolin-8-ol (1), 5-(benzo[]thiazol-2-yl)quinolin-8-ol (2), and 4-(1-benzo[]imidazol-2-yl)benzene-1,3-diol (3), were synthesized, and their fluoride (F) ion binding properties were investigated. These ligands could selectively bind F ions, and their respective F complexes, namely, 1-TBAF, 2-TBAF, and 3-TBAF (TBAF = tetrabutylammonium fluoride), were characterized using single crystal X-ray analysis, NMR, UV-vis, Hirshfeld surface (HS) analysis and computational studies.

Osseointegration of Implants Through Ti Biofunctionalization with Biomass from UTEX 1230 and sp. PCC 7002.

The inadequate osseointegration of titanium implants remains a significant challenge in orthopedics, limiting the long-term efficacy of prostheses and medical devices. It has been determined that biological aging of the titanium surface compromises the implant-bone tissue interaction due to increased hydrophobicity and accumulation of organic molecules. To address this issue, an innovative strategy has been proposed: the biofunctionalization of Ti6Al4V surfaces utilizing biomass derived from UTEX 1230 and sp.

A framework to automatically detect near-falls using a wearable inertial measurement cluster.

Accurate and automatic assessments of body segment kinematics via wearable sensors are essential to provide new insights into the complex interactions between active lifestyle and fall risk in various populations. To remotely assess near-falls due to balance disturbances in daily life, current approaches primarily rely on biased questionnaires, while contemporary data-driven research focuses on preliminary fall-related scenarios. Here, we worked on an automated framework based on accurate trunk kinematics, enabling the detection of near-fall scenarios during locomotion.

Livestock abortion surveillance in Tanzania reveals disease priorities and importance of timely collection of vaginal swab samples for attribution.

Lack of data on the aetiology of livestock diseases constrains effective interventions to improve livelihoods, food security and public health. Livestock abortion is an important disease syndrome affecting productivity and public health. Several pathogens are associated with livestock abortions but across Africa surveillance data rarely include information from abortions, little is known about aetiology and impacts, and data are not available to inform interventions.

MIBiG 4.0: advancing biosynthetic gene cluster curation through global collaboration.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.
