Colorectal cancer (CRC) is one of the leading causes of cancer related deaths in the world. Many oncogenes and tumor suppressor genes are involved in the development of CRC. MicroRNAs (miRNAs) are a class of small, non-coding, endogenous RNAs in animals and plants. Recent studies have shown that miRNAs are associated with the mediation process of tumorigenesis, including inflammation, cell cycle, stress response, differentiation, apoptosis, migration, and invasion in cancer. These miRNAs have been linked to the development of CRC and recently studied as new potential biomarkers in the diagnosis and treatment for CRC...

The response of plants to copper oxide nanoparticles (nano-CuO) in presence of exogenous phytohormones is unknown. In this study, green pea (Pisum sativum) plants were cultivated to full maturity in soil amended with nano-CuO (10-100nm, 74.3% Cu), bulk-CuO (bCuO, 100-10,000nm, 79.7% Cu), and CuCl2 at 50 and 100mg/kg and indole-3-acetic acid (IAA) at 10 and 100μM. Results showed that IAA at 10 and 100μM, averaged over all Cu treatments, reduced the number of plants by ~23% and ~34%, respectively. IAA at 10μM, nano-CuO at 50mg/kg, b-CuO at 50mg/kg, and CuCl2 at 100mg/kg reduced pod biomass by about 50%...

Combined application of plant residues and N fertilisers strongly affect soil mineral N dynamics and N2O emissions depending on the quality of the plant residues, their application methods and other management strategies. We investigated the effect of combined application of two vegetable plant residues (cauliflower and sweet corn) and (15)N fertiliser on N dynamics and N2O emission in a glasshouse pot study. The experiment was conducted under two residue management practices (soil incorporation vs surface mulching) over 98days with growing basil (Ocimum basilicum) plants...

Glycolipids are the major constituent of the thylakoid membrane of higher plants and have a variety of biological and pharmacological activities. However, anti-inflammatory effects of glycolipids on vascular endothelial cells have not been elucidated. Here, we investigated the effect of glycolipids extracted from spinach on lipopolysaccharides (LPS)-induced endothelial inflammation and evaluated the underlying molecular mechanisms. Treatment with glycolipids from spinach had no cytotoxic effects on cultured human umbilical vein endothelial cells (HUVECs) and significantly blocked the expression of LPS-induced interleukin (IL)-6, monocyte chemoattractant protein-1 (MCP-1), vascular cell adhesion molecule-1 (VCAM-1), and intracellular adhesion molecule-1 (ICAM-1) in them...

Aluminum (Al) is the third most abundant metal in earth crust, whose chemical form is mainly dependent on soil pH. The most toxic form of Al with respect to plants is Al3+, which exists in soil pH <5. Acidic soil significantly limits crop production mainly due to Al3+ toxicity worldwide, impacting approximately 50% of the world's arable land (in North-Eastern India 80% soil are acidic). Al3+ toxicity in plants ensues root growth inhibition leading to less nutrient and water uptake impacting crop productivity as a whole...

Worldwide, diabetic foot ulcers (DFUs) continue to exact a major burden on patients and health care providers. Although hyperbaric oxygen therapy is well-known as an adjunct option, less is known about the efficacy of transdermal continuous oxygen therapy (TCOT). A prospective, randomized, blinded, multicenter, parallel study was conducted from October 2009 to November 2012 to evaluate healing time and the proportion of DFUs healed after 12 weeks of moist wound therapy (MWT) with or without TCOT. Study participants (persons with type 1 or type 2 diabetes and a nonhealing [>1-month but <1-year duration], 1 cm² to 10 cm² in area, infection-free DFU) were randomized to TCOT or a sham device (control) in addition to receiving MWT...

Anti-tumor therapies based on anti-inflammatory effects have been considered in cancer treatment. Survival, proliferation and, resultantly, invasion and metastasis of tumor cells are regulated by local inflammatory mediators. Primary inflammatory cytokines, such as tumor necrosis factor (TNF), are targets for anticancer therapy. Several anti‑inflammatory agents isolated from natural products are becoming important chemopreventive and therapeutic agents for cancer. The present study aimed to investigate the expression of TNF‑α, nuclear factor‑κΒ (NF‑κΒ) and p38α mitogen-activated protein kinase (p38α) genes, associated with proliferation and inflammation in the Caco‑2 cell line treated with ethanolic and hexanic extracts of Calyptranthes grandifolia O...

Glutamate-induced excitotoxicity is one of the major underlying mechanisms for neurodegenerative diseases. Efforts are being made to treat such conditions with an array of natural compounds that can modulate the release of glutamate or the underlying mechanisms associated with it. Withania somnifera extract has potent pharmacologic activity similar to that of Korean Ginseng tea and is used to treat several neuronal disorders. However, to date, little efforts have been made to evaluate individual constituents of this plant for neurodegenerative disorders...

Damask rose (Rosa damascena Mill.) is one of the most high-value essential oil-bearing plants in the world. However, the flower yield and quality of essential oil of R. damascena are largely influenced by the pruning practices and balanced supply of plant nutrition. The objective of this study was to test the hypothesis whether the pruning system and foliar fertilization of MgSO4 would influence the flower yield, growth and secondary metabolites profile of R. damascena. A field experiment of 10 treatment combinations comprising two pruning systems (complete and partial) and five levels of MgSO4 (water spray, MgSO4 @ 5...
