Monocytes and interstitial macrophages contribute to hypoxic pulmonary hypertension.

Hypoxia is a major cause of pulmonary hypertension (PH) worldwide, and it is likely that interstitial pulmonary macrophages contribute to this vascular pathology. We observed in hypoxia-exposed mice an increase in resident interstitial macrophages, which expanded through proliferation and expressed the monocyte recruitment ligand CCL2. We also observed an increase in CCR2+ macrophages through recruitment, which express the protein thrombospondin-1 that functionally activates TGF-beta to cause vascular disease.

Chitosan-Functionalized Fluorescent Calcium Carbonate Nanoparticle Loaded with Methotrexate: Future Theranostics for Triple Negative Breast Cancer.

Herein, fluorescent calcium carbonate nanoclusters encapsulated with methotrexate (Mtx) and surface functionalized with chitosan (25 nm) (@Calmat) have been developed for the imaging and treatment of triple-negative breast cancer (TNBC). These biocompatible, pH-sensitive nanoparticles demonstrate significant potential for targeted therapy and diagnostic applications. The efficacy of nanoparticles (NPs) was evaluated in MDA-MB-231 TNBC cell lines.

Explanatory review on DDR inhibitors: their biological activity, synthetic route, and structure-activity relationship.

Discoidin domain receptors (DDR) are categorized under tyrosine kinase receptors (RTKs) and play a crucial role in various etiological conditions such as cancer, fibrosis, atherosclerosis, osteoarthritis, and inflammatory diseases. The structural domain rearrangement of DDR1 and DDR2 involved six domains of interest namely N-terminal DS, DS-like, intracellular juxtamembrane, transmembrane juxtamembrane, extracellular juxtamembrane intracellular kinase domain, and the tail portion contains small C-tail linkage. DDR has not been explored to a wide extent to be declared as a prime target for any particular pathological condition.

Mechanistic studies of chondroitin sulfate/dermatan sulfate isolated from freshwater fish discards on osteogenesis in MC3T3-E1 cells.

Glycosaminoglycans (GAGs) are essential bone extracellular matrix molecules that regulate osteoblast differentiation. Numerous studies have explored endogenous and exogenous GAG osteoanabolic activities using appropriate in vitro and in vivo models. However, GAGs' underlying the mechanism of action and structure-function relationships need to be elucidated in detail.

Effect of Botulinum toxin on non-motor symptoms in adult-onset idiopathic focal/segmental dystonia.

Background: Non-motor symptoms, including depression, anxiety, sleep disturbances, pain and cognitive dysfunction, are a much more important predictor of quality of life than the severity of dystonia.

Objectives: To assess the effect of Botulinum toxin on non-motor symptoms and quality of life in patients with adult-onset idiopathic focal dystonia.

Methods: Patients aged > 18 years diagnosed with idiopathic focal dystonia were recruited in this longitudinal cohort study.

Uncovering the intricacies of IGF-1 in Alzheimer's disease: new insights from regulation to therapeutic targeting.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid-β plaques and tau tangles, leading to cognitive decline and dementia. Insulin-like Growth Factor-1 (IGF-1) is similar in structure to insulin and is crucial for cell growth, differentiation, and regulating oxidative stress, synaptic plasticity, and mitochondrial function. IGF-1 exerts its physiological effects by binding to the IGF-1 receptor (IGF-1R) and activating PI3K/Akt pathway.

Chemical composition, antibacterial and antioxidant activities of Piper betle and Anethum graveolens essential oils against Methicillin-resistant Staphylococcus aureus clinical isolates.

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the leading causes of infection worldwide due to its antimicrobial resistance. Plant-derived essential oils (EOs) have undergone extensive observational and clinical research to explore their antimicrobial properties. The present study aimed to check mec A positive MRSA isolates using sequencing analysis, determination of chemical composition using gas chromatography-mass spectroscopy (GC-MS), antioxidant, and antimicrobial activity of Anethum graveolens and Piper betle EOs against the infectious agent MRSA.

Anti-melanoma differentiation-associated gene 5 antibody-positive interstitial lung disease masquerading as rheumatoid arthritis-associated interstitial lung disease or overlapping with the same: a phenomenon driven by a probable genetic predisposition.

Rheumatoid arthritis (RA) is a systemic, progressive illness marked by persistent synovitis that causes substantial functional disability. Treatment delays frequently affect health-related quality of life. Extra-articular features are prevalent findings in RA, which leads to significant morbidity and mortality.

Transcriptomic insight into zinc dependency of vindoline accumulation in Catharanthus roseus leaves: relevance and potential role of a CrZIP.

Foliar-applied Zn on Catharanthus roseus enhanced production of vindoline, the main impediment precursor for costly anticancer bisindoles. A leaf-abundant CrZIP was characterized for likely role in modulating vindoline metabolism. The leaf-localized Catharanthus roseus alkaloid, vindoline, is the major impediment precursor in the production of scanty and expensive anticancer bisindoles, vinblastine and vincristine.

Iron oxide nanoparticles coated with bioactive materials: a viable theragnostic strategy to improve osteosarcoma treatment.

Osteosarcoma (OS) is distinguished as a high-grade malignant tumor, characterized by rapid systemic metastasis, particularly to the lungs, resulting in very low survival rates. Understanding the complexities of tumor development and mutation is the need of the hour for the advancement of targeted therapies in cancer care. A significant innovation in this area is the use of nanotechnology, specifically nanoparticles, to tackle various challenges in cancer treatment.

Prediction of dry matter intake in growing Black Bengal goats using artificial neural networks.

Dry matter intake (DMI) determination is essential for effective management of meat goats, especially in optimizing feed utilization and production efficiency. Unfortunately, farmers often face challenges in accurately predicting DMI which leads to wastage of feed and an increase in the cost of production. This investigation aimed to predict DMI in Black Bengal goats by using body weight (BW), body condition score (BCS), average daily gain (ADG), and metabolic body weight (MBW) by applying an artificial neural network (ANN) model.
