Targeting Gastrointestinal Cancers with Carvacrol: Mechanistic Insights and Therapeutic Potential.

Gastrointestinal (GI) cancers, including esophageal, gastric, pancreatic, liver, and colorectal malignancies, represent a major global health burden due to their high incidence, aggressive nature, and limited treatment outcomes. This review explores the therapeutic potential of carvacrol, a naturally occurring monoterpenoid phenol predominantly found in oregano and other aromatic plants. Carvacrol has demonstrated strong anticancer properties by modulating multiple molecular pathways governing apoptosis, inflammation, angiogenesis, and metastasis.

Role of emodin to prevent gastrointestinal cancers: recent trends and future prospective.

Gastrointestinal malignancies are responsible for approximately 35% of all cancer-related deaths, underscoring the critical need to explore pharmacologically active molecules for chemoprevention. Emodin (1,3,8-trihydroxy-6-methylanthraquinone), a natural compound derived from traditional Chinese and Japanese medicine, has recently garnered significant attention for its potential anticancer properties. Emodin exerts its chemoprotective effects through a combination of antioxidative, anti-inflammatory, and anti-proliferative mechanisms.

Cra-controlled antisense RNA-downregulation of isocitrate dehydrogenase in Escherichia coli.

Catabolite repressor activator (Cra) protein (formerly called FruR) found in E. coli is known to regulate the expression of many genes positively and negatively in response to the intracellular levels of fructose-1-phosphate (F-1-P) and fructose-1,6-bisphopahate (F-1,6-bisP). In this paper, we report synthesis and characterization of a conditionally expressed antisense RNA corresponding to 101 bp of isocitrate dehydrogenase (icd) gene (as-icd) under Cra (FruR) responsive promoter fruB (P as-icd construct denoted as pVS2K3) in E.

Mechanistic Insight of Pharmacological Aspects of Violacein: Recent Trends and Advancements.

Since its discovery in the bacterium Chromobacterium violaceum, violacein-a striking purple pigment-has garnered significant interest due to its promising applications in the food and pharmaceutical industries. Violacein exhibits a range of pharmacological properties, including anti-inflammatory, anticancer, antibacterial, and antiparasitic effects, yet its complete molecular mechanisms are still being elucidated. Its mechanisms of action likely involve complex interactions with cellular receptors, signaling pathways, and specific molecular targets.

A review of the effects of environmental hazards on humans, their remediation for sustainable development, and risk assessment.

In the race for economic development and prosperity, our earth is becoming more polluted with each passing day. Technological advances in agriculture and rapid industrialization have drastically polluted the two pillars of natural resources, land and water. Toxic chemicals and microbial contaminants/agents created by natural and anthropogenic activities are rapidly becoming environmental hazards (EH) with increased potential to affect the natural environment and human health.

Performance investigations on data protection algorithms in generalized multi protocol label switched optical networks.

In future generation networks, data protection is a crucial necessity particularly when information is sent on a system. Network protection has three objectives known as discretion, reliability and accessibility. The most common procedure exploited to attain this ambition is encryption.

In silico prediction, characterization and molecular docking studies on Glutathione-S-transferase as a molecular sieve for toxic agrochemicals explored in survey of North Indian farmers.

All across the globe, India is considered as an agricultural nation because its agro products drive the economy. An increase in population growth and a hike in food demands lead to the use of hazardous chemicals in farm fields. An in-depth field survey in Northern India was conducted to understand the types of agrochemicals that were used, farmers' knowledge about their safe handling, and their practices on its usage.

Molecular characterization and DNA methylation profile of from oil polluted soil.

Studies on earthworms using molecular markers are rare in Africa except a handful from South Africa. Reports on , an earthworm found in West Africa are available including their metal tolerance and bioaccumulation capacity but their molecular characterization and ecotoxicology studies are scarce. In this study, triplicate specimens were collected from four locations within a petroleum polluted site and one in a control site, ≃1Km away from point of spill.

Addressing Stem Cell Therapeutic Approaches in Pathobiology of Diabetes and Its Complications.

High morbidity and mortality of diabetes mellitus (DM) throughout the human population is a serious threat which needs to be addressed cautiously. Type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) are most prevalent forms. Disruption in insulin regulation and resistance leads to increased formation and accumulation of advanced end products (AGEs), which further enhance oxidative and nitrosative stress leading to microvascular (retinopathy, neuropathy, and nephropathy) and macrovascular complications.

Combating Osteoarthritis through Stem Cell Therapies by Rejuvenating Cartilage: A Review.

Knee osteoarthritis (OA) is a chronic degenerative disorder which could be distinguished by erosion of articular cartilage, pain, stiffness, and crepitus. Not only aging-associated alterations but also the metabolic factors such as hyperglycemia, dyslipidemia, and obesity affect articular tissues and may initiate or exacerbate the OA. The poor self-healing ability of articular cartilage due to limited regeneration in chondrocytes further adversely affects the osteoarthritic microenvironment.

Effect of different combinations of antibodies and enzyme labels on ELISA of progesterone.

In steroid immunoassays, selection of right combination of antibody and enzyme-labeled antigen determine the sensitivity and specificity of ELISA. Antibodies raised against different positions of progesterone adopting heterologous systems were reported to provide better assays for progesterone. Four different antibodies developed against progesterone-11α-hemiglutarate-BSA (P-11-HG-BSA), progesterone-11α-hemisuccinate-BSA (P-11-HS-BSA), progesterone-3-O-carboxymethyloxime-BSA (P-3-CMO-BSA), and progesterone-3-O-carboxymethyloxime-ovalbumin (P-3-CMO-ova) were tested in combination with enzyme-labeled P-11-HG, P-11-HS, progesterone-11α-carboxymethyl ether (P-11-CME), P-3-CMO, 17-hydroxyprogesterone-3-O-carboxymethyl oxime (17-P-3-CMO), and progesterone-4-carboxymethyl thioether (P-4-CMTE).

Influence of iodothyronine conjugates of bovine serum albumin and horseradish peroxidase on enzyme immunosorbent assay of thyroid hormones.

Enzyme-linked immunosorbent assays (ELISA's) reported for thyroxine (T₄) and 3,5,3'-triiodothyronine (T₃), involved coupling of the haptens through (i) carboxylic group to carrier protein for producing antibodies and (ii) amino group to detection labels. To improve the titer and specificity of antibodies, immunogens were prepared by coupling of carboxyl group to bovine serum albumin (BSA) either directly or through adipic acid dihydrazide (ADH), after protecting amino group through acetylation of T₄ and T₃. Direct coupling resulted in the incorporation of 40-50 moles of T₄ and T₃ per BSA molecule and helped in improving immunogenic response and specificity, especially of T₄.
