During the present time, anti-microbial features of copper (Cu) and zinc oxide (ZnO) nanoparticles (NPs) are extensively used to combat the growth of pathogenic microbes. CuNPs and ZnONPs are recurrently used in cosmetics, medicine and food additives, and their potential for toxic impacts on human and ecosystem is of high concern. In this study, the fate and toxicity of 16- to 96-nm-ranged bios...

to evaluate the effect of chemical and bio-fertilizer on nitrogen, phosphorus and potash concentration, biochemical traits and calyxes yield of roselle, an experiment was conducted in the split plot based on randomized coplete block design with three replications, at the research station in zabol university, during 2013 and 2014. the main plot consisted of three levels: phosphorus, nitrogen and...

Nanotechnology (nano-materials and nano-process) has been developed for both industrial and medical applications. The use of nano-medicine has been used in bio-imaging and bio-sensing, drug delivery, cancer cell diagnostics and therapeutics [1,2]. Nanoparticles (NPs) can cause tumor cell death by photothermal ablation, photodynamic toxicity, mechanical damage, or increase in the localized drug ...

Background This research studies the effects of activation and inhibition of Wnt3A signaling pathway in buffalo (Bubalus bubalis) embryonic stem (ES) cell-like cells. MaterialsAndMethods To carry on this experimental study, the effects of activation and inhibition of Wnt3A signaling in buffalo ES cell-like cells were examined using Bio (0.5 mM) combined with WNT3A (200 ng/ml), as an activator, ...

Adipose-derived cytokines play a prominent role in mediating the metabolic consequences of obesity and excess body fat. Given this, we hypothesized that alterations in adipose tissue stores incurred with exercise training would be reflected in changes in systemic cytokine concentrations. The Studies of Targeted Risk Reduction Intervention through Defined Exercise, where pronounced changes in ad...

The planting of trees on mine wastelands is an effective, long-term technique for phytoremediation of heavy metal-contaminated wastes. In this study, a pot experiment with seedlings of Koelreuteria paniculata under six treatments of local mine wastes was designed to determine the major constraints on tree establishment and to evaluate the feasibility of planting K. paniculata on manganese mine ...

Bio-aerosols are airborne particles that are living (bacteria, viruses and fungi) or originate from living organisms. Their presence in air is the result of dispersal from a site of colonization or growth. The health effects of bio-aerosols including infectious diseases, acute toxic effects, allergies and cancer coupled with the threat of bioterrorism and SARS have led to increased awareness on...

Bio-oils from the fast pyrolysis of switchgrass forage and two sets of alfalfa stems (from two stages of developmentsbud and full flower stages) have been analyzed by wet-chemical methods, GC-MS, and HPLC. The chemical composition of bio-oil is important because it may give insights into its quality, stability, or suitability for downstream upgrading. Pyrolysis experiments were conducted at 500...
