Molecular insights into Wnt3a and Wnt5a gene expression in venous insufficiency.

Background: Chronic venous insufficiency (CVI) manifests as morphological and functional abnormalities in the venous system, primarily affecting the lower extremities and presenting as leg heaviness, oedema, and varicose veins. CVI is a common vascular disorder characterised by impaired blood flow in the veins, often leading to various clinical manifestations. To better understand the additional underlying mechanisms of CVI, it is essential to explore the role of Wnt proteins, which play a crucial role in regulating signalling processes.

CREB1 promotes expression of immune checkpoint HLA-E leading to immune escape in multiple myeloma.

Multiple myeloma (MM) cells effectively escape anti-tumoral immunity to survive in the tumor microenvironment (TME). Herein, we identify non-classical major histocompatibility complex (MHC) class I molecule HLA-E as a major contributing factor in immune escape. Clinically, HLA-E expression correlates with aggressive disease features such as t(4;14) and CD56 expression and is induced by IFN-gamma (IFN-γ) in the TME.

Understanding DNA Damage Response and DNA Repair in Multiple Myeloma.

Multiple myeloma (MM) is a plasma cell malignancy characterized by several genetic abnormalities, including chromosomal translocations, genomic deletions and gains, and point mutations. DNA damage response (DDR) and DNA repair mechanisms are altered in MM to allow for tumor development, progression, and resistance to therapies. Damaged DNA rarely induces an apoptotic response, given the presence of ataxia-telangiectasia mutated () loss-of-function or mutations, as well as deletions, mutations, or downregulation of tumor protein p53 (TP53) and tumor protein p73 (TP73).

Thermal micropolar and couple stresses effects on peristaltic flow of biviscosity nanofluid through a porous medium.

The main aim of the current study is to analyze couple stresses effects on MHD peristaltic transport of a micropolar non-Newtonian nanofluid. The fluid flows through a porous media between two horizontal co-axial tubes. The effects of radiation, chemical reaction, viscous and ohmic dissipation are considered.

Synthesis of aromatic lactone analogues of Lipoxin A4.

Objective: Synthesis of novel aromatic Lipoxin A4 lactone analogues.

Results: Novel para-substituted aromatic lactone analogues of Lipoxin A4 have been synthesized in a convergent manner with six steps in the longest linear sequence in 12-13% yields, employing 2-deoxy-D-ribose as a chiral pool starting material and the classical E-selective Wittig olefination.

Structural studies of triazole inhibitors with promising inhibitor effects against antibiotic resistance metallo-β-lactamases.

Metallo-β-lactamases (MBLs) are an emerging cause of bacterial antibiotic resistance by hydrolysing all classes of β-lactams except monobactams, and the MBLs are not inhibited by clinically available serine-β-lactamase inhibitors. Two of the most commonly encountered MBLs in clinical isolates worldwide - the New Delhi metallo-β-lactamase (NDM-1) and the Verona integron-encoded metallo-β-lactamase (VIM-2) - are included in this study. A series of several NH-1,2,3-triazoles was prepared by a three-step protocol utilizing Banert cascade reaction as the key step.

Carbonylative Suzuki-Miyaura couplings of sterically hindered aryl halides: synthesis of 2-aroylbenzoate derivatives.

We have developed a carbonylative approach to the synthesis of diversely substituted 2-aroylbenzoate esters featuring a new protocol for the carbonylative coupling of aryl bromides with boronic acids and a new strategy to favour carbonylative over non-carbonylative reactions. Two different synthetic pathways - (i) the alkoxycarbonylation of 2-bromo benzophenones and (ii) the carbonylative Suzuki-Miyaura coupling of 2-bromobenzoate esters - were evaluated. The latter approach provided a broader substrate tolerance, and thus was the preferred pathway.

Interactive association between processing induced molecular structure changes and nutrient delivery on a molecular basis, revealed by cutting-edge vibrational biomolecular spectroscopy.

Background: This study was conducted to determine protein molecular structure profiles and quantify the relationship between protein structural features and protein metabolism and bioavailability of blend pelleted products (BPP) based on co-products (canola or carinata) from processing with different proportions of pulse pea screenings and lignosulfonate chemical compound.

Method: The protein molecular structures were determined using the non-invasive advanced vibrational molecular spectroscopy (ATR-FT/IR) in terms of chemical structure and biofunctional groups of amides (I and II), α-helix and β-sheet.

Results: The results showed that increasing the level of the co-products in BPP significantly increased the spectral intensity of the amide area and amide height.

Connection of inherent structure with nutrient profiles and bioavailability of different co-products and by-products after processing using advanced grading and vibrational molecular spectroscopy.

This study aims to reveal connection and implication of molecular structure with nutrient profiles, utilization and bioavailability of both conventional and new co-products from bio-energy and bio-oil processing using grading and vibrational molecular spectroscopy with chemometics including univariate and multivariate techniques. The study focused on strategies to improve the utilization of the conventional and new co-products through chemical and heat processing treatments as well as the relationship of the molecular structural changes to nutrient bioavailability. The updated methods advanced molecular spectroscopy techniques with grading NIR, Globar FTIR, ATR-FTIR and Synchrotron SRFTIRM to study feed molecular structures were reviewed.

A focused fragment library targeting the antibiotic resistance enzyme - Oxacillinase-48: Synthesis, structural evaluation and inhibitor design.

β-Lactam antibiotics are of utmost importance when treating bacterial infections in the medical community. However, currently their utility is threatened by the emergence and spread of β-lactam resistance. The most prevalent resistance mechanism to β-lactam antibiotics is expression of β-lactamase enzymes.
