Impact of combinatorial immunotherapies in breast cancer: a systematic review and meta-analysis.

Background: Breast cancer has the highest mortality rate among all cancers affecting females worldwide. Several new effective therapeutic strategies are being developed to minimize the number of breast cancer-related deaths and improve the quality of life of breast cancer patients. However, resistance to conventional therapies in breast cancer patients remains a challenge which could be due to several reasons, including changes in the tumor microenvironment.

Plasmodium berghei HMGB1 controls the host immune responses and splenic clearance by regulating the expression of pir genes.

High mobility group box (HMGB) proteins belong to the high mobility group (HMG) superfamily of non-histone nuclear proteins that are involved in chromatin remodeling, regulation of gene expression, and DNA repair. When extracellular, HMGBs serve as alarmins inducing inflammation, and this is attributed to the proinflammatory activity of box B. Here, we show that Plasmodium HMGB1 has key amino acid changes in box B resulting in the loss of TNF-α stimulatory activity.

Synthesis, molecular modelling studies of artemisinin-chalcone derivatives and their antimalarial activity evaluation.

Twenty-two monomers and dimers of artemisinin having chalcone as a linker were synthesised, and their antimalarial activity against was determined, and a quantitative structure-activity relationship (QSAR) was developed. Artemisinin is a frontline antimalarial drug known worldwide but is threatened because of the rapidly emerging artemisinin-resistant strain , antimalarial IC (half-maximal inhibitory concentration) activity of a molecule against malaria parasites provides a good first screen for identifying the antimalarial potential of a particular molecule. The most active compound was artemisinin dimer dimethoxy chalcone as a linker with IC of 4.

Antibiotic Potentiation Through Phytochemical-Based Efflux Pump Inhibitors to Combat Multidrug Resistance Bacteria.

Background: Antimicrobial resistance development poses a significant danger to the efficacy of antibiotics, which were once believed to be the most efficient method for treating infections caused by bacteria. Antimicrobial resistance typically involves various mechanisms, such as drug inactivation or modification, drug target modification, drug uptake restriction, and drug efflux, resulting in decreased antibiotic concentrations within the cell. Antimicrobial resistance has been associated with efflux Pumps, known for their capacity to expel different antibiotics from the cell non-specifically.

Heteroleptic Cu(I) bis-diimine complexes as sensitizers in dye-sensitized solar cells (DSSCs): on some factors affecting intramolecular charge transfer.

A set of eight heteroleptic bis-diimine copper dye complexes with two different ancillary ligands (functionalised 2,9-dimethyl-1,10-phenanthroline (dmp) and functionalised 6,6'-diphenyl-2,2'-bipyridine (dpbpy)) are investigated for their potential use as sensitizers in dye-sensitized solar cells (DSSCs), using first principles density functional theory (DFT) and time dependent DFT (TDDFT). A detailed analysis of the structural properties, projected density of electronic states and Kohn-Sham energy levels, and optical absorption spectra in the UV-visible region reveals that substituting the thiophene group in the ancillary ligand, and enhancing conjugation in the anchoring ligand, lead to increase in the light harvesting efficiency (LHE). However, a natural transition orbital (NTO) analysis, shows that the nature of charge transfer depends mainly on the nature of the parent ancillary group and is not significantly affected by the structural modifications.

Base pairs with 4-amino-3-nitrobenzonitrile: comparison with the natural WC pairs. Dimer and tetramer forms, Infrared and Raman spectra, and several proposed antiviral modified nucleosides.

Base pairs of 4-amino-3-nitrobenzonitrile (4A-3NBN) molecule with uracil, thymine and cytosine nucleobases were optimized and compared to natural Watson-Crick (WC) pairs. The slightly greater flexibility of the -NO group of 4A-3NBN than the N3-H group of the natural nucleobases together with a noticeable higher dipole moment of its pairs can facilitate disruption of the DNA/RNA helix formation. Several new mutagenic modified nucleosides with 4A-3NBN and 3-amino-2-nitrobenzonitrile (3A-2NBN) were proposed as antiviral prodrugs and their base pairs optimized.

Morpho-physiological studies revealed better cyto-morphology of tolerant genotypes over sensitive under Al stress conditions.

Plant epigenomics for extenuation of abiotic stresses: challenges and future perspectives.

Climate change has escalated abiotic stresses, leading to adverse effects on plant growth and development, eventually having deleterious consequences on crop productivity. Environmental stresses induce epigenetic changes, namely cytosine DNA methylation and histone post-translational modifications, thus altering chromatin structure and gene expression. Stable epigenetic changes are inheritable across generations and this enables plants to adapt to environmental changes (epipriming).
