Comprehensive evaluation of antibacterial and anticancer activities from indole butanoic acid.

Focus of this study is on the use of the hydrazone compound (3) (N-(4-bromobenzylidene)-4-(1H-indol-3-yl) butane hydrazide), which was previously prepared from the reaction of the compound p-bromobenzaldehyde with the corresponding hydrazide (2), as an intermediate compound for the synthesis of azetidine, thiazolidine, tetrazole, oxadiazole and phthalazine heterocyclic compounds through its reaction with some cyclic reagents and catalysts such as chloro acetyl chloride, thioglycolic acid, sodium-azid, lead dioxide and Hydrogen chloride gas. The prepared compounds were characterized using physical properties and also spectroscopic methods such as infrared spectroscopy, nuclear magnetic resonance spectra of the proton and the isotope of carbon as well as mass spectrometry, which accurately identified the proposed structures of the prepared compounds. The identity of the prepared compounds was determined using physical and spectroscopic properties, where infrared and HNMR spectroscopy of the proton as well as carbon were used in addition to using mass spectrometry to verify the validity of the prepared structures.

Tumor-derived extracellular vesicles convey solute transporters to induce bioenergetic dependence shift contributing to treatment resistance.

Growing evidence points to the tumor microenvironment's role in developing drug resistance. A key element of this microenvironment is inter-cellular communication, which includes the release of membrane-encapsulated vesicles containing various cargo, known as extracellular vesicles (EVs). Understanding how EVs contribute to acquired resistance holds significant clinical implications.

Methods: Twelve high-functioning patients with unilateral posterior stabilizing knee implants underwent CT-guided robotic-arm assisted surgery.

Editing microbes to mitigate enteric methane emissions in livestock.

Livestock production significantly contributes to greenhouse gas (GHG) emissions particularly methane (CH) emissions thereby influencing climate change. To address this issue further, it is crucial to establish strategies that simultaneously increase ruminant productivity while minimizing GHG emissions, particularly from cattle, sheep, and goats. Recent advancements have revealed the potential for modulating the rumen microbial ecosystem through genetic selection to reduce methane (CH) production, and by microbial genome editing including CRISPR/Cas9, TALENs (Transcription Activator-Like Effector Nucleases), ZFNs (Zinc Finger Nucleases), RNA interference (RNAi), Pime editing, Base editing and double-stranded break-free (DSB-free).

Catch composition, catch per unit effort (CPUE) and species selectivity of fishing gears on multi-species Kaptai Lake in Bangladesh.

Kaptai Lake, the largest artificial reservoir in Southeast Asia, is home to a diverse fish fauna that supports thousands of livelihoods and is distinguished by multi-species and multi-gear fisheries. In Kaptai Lake, the gear-based catch composition, catch rate and distribution pattern are little known. From August 2020 to April 2021, a nine-month study was conducted in five using direct catch assessment surveys and fishing effort surveys from four fishing gears, namely seine nets, gill nets, lift nets, and push nets.

Advances in Non-Small Cell Lung Cancer (NSCLC) Treatment-A Paradigm Shift in Oncology.

Non-Small Cell Lung Cancer (NSCLC) management remains a formidable challenge in the field of oncology, representing a significant global health burden [...

Robotic-assisted Total Knee Arthroplasty Technology Provides a Repeatable and Reproducible Method of Assessing Soft Tissue Balance.

Soft-tissue balancing is an important factor in primary total knee arthroplasty (TKA), with 30 to 50% of TKA revisions attributed to technical operative factors including soft-tissue balancing. Robotic-assisted TKA (RATKA) offers opportunities for improved soft-tissue balancing methods. This study aimed to evaluate the repeatability and reproducibility of ligamentous laxity assessments during RATKA using a digital tensioner.

How various stakeholder pressure influences mega-project sustainable performance through corporate social responsibility and green competitive advantage.

Although numerous research studies have revealed that mega-projects are closely linked to globalization and civilization, few researchers have performed logical assessments of mega-projects using stakeholder theory. As stakeholders demand greater sustainability in the construction industry, sustainable development (SD) has become a priority. However, corporate social responsibility (CSR) and green competitive advantage (GCA) have often been overlooked.

Recent advances in chromosome capture techniques unraveling 3D genome architecture in germ cells, health, and disease.

In eukaryotes, the genome does not emerge in a specific shape but rather as a hierarchial bundle within the nucleus. This multifaceted genome organization consists of multiresolution cellular structures, such as chromosome territories, compartments, and topologically associating domains, which are frequently defined by architecture, design proteins including CTCF and cohesin, and chromatin loops. This review briefly discusses the advances in understanding the basic rules of control, chromatin folding, and functional areas in early embryogenesis.

Targeting Inflammation in Non-Small Cell Lung Cancer through Drug Repurposing.

Lung cancer is the most common cause of cancer-related deaths. Lung cancers can be classified as small-cell (SCLC) or non-small cell (NSCLC). About 84% of all lung cancers are NSCLC and about 16% are SCLC.

Effects of Leea indica leaf extracts and its phytoconstituents on natural killer cell-mediated cytotoxicity in human ovarian cancer.

Background: The rich biodiversity of medicinal plants and their importance as sources of novel therapeutics and lead compounds warrant further research.

Effects of Weight-Bearing on Tibiofemoral, Patellofemoral, and Patellar Tendon Kinematics in Older Adults.

Unlabelled: Quantification of natural knee kinematics is essential for the assessment of joint function in the diagnosis of pathologies. Combined measurements of tibiofemoral and patellofemoral joint kinematics are necessary because knee pathologies, such as progression of osteoarthritis and patellar instability, are a frequent concern in both articulations. Combined measurement of tibiofemoral and patellofemoral kinematics also enables calculation of important quantities, specifically patellar tendon angle, which partly determines the loading vector at the tibiofemoral joint and patellar tendon moment arm.

Protein Lipidation by Palmitoylation and Myristoylation in Cancer.

Posttranslational modification of proteins with lipid moieties is known as protein lipidation. The attachment of a lipid molecule to proteins endows distinct properties, which affect their hydrophobicity, structural stability, localization, trafficking between membrane compartments, and influences its interaction with effectors. Lipids or lipid metabolites can serve as substrates for lipidation, and the availability of these lipid substrates are tightly regulated by cellular metabolism.
