Plastic pollution has been prevalent in the world ever since its use majority of areas including packaging, electronic industries, building and construction, healthcare, transportation etcetera. This lead to a constantly increasing burden on environment which attracted many environmentalists scientists towards working different ways cope up with this threat. Many studies have done find out naturally degrade plastics using hidden capabilities microbes that can these as their sole carbon...
Photocopiers emit large quantities of nanoparticles (NPs); however, their toxicological properties have not been studied. Here we investigate for the first time early human responses following a day's exposure to NPs from photocopiers. Nine healthy subjects spent 6 h at busy photocopy centre on 2-3 randomly selected days. Matched nasal lavage and urine samples were collected before different points post-exposure. Nasal analysed 14 cytokines, inflammatory cells total protein. Urine...
Recent developments in nanotechnology and engineering have produced a plethora of nanomaterials with amazing physical/chemical properties enhanced sensing potential for various heavy metals the environment.
Photocopiers emit nanoparticles with complex chemical composition. Short-term exposures to modest nanoparticle concentrations triggered upper airway inflammation and oxidative stress in healthy human volunteers a recent study. To further understand the toxicological properties of copier-emitted nanoparticles, we studied in-vitro their ability induce cytotoxicity, pro-inflammatory cytokine release, DNA damage, apoptosis relevant cell lines.Three types were used: THP-1, primary nasal- small...
Phytotoxins are poisonous substances synthesized by plants or plant pathogens through naturally occurring biochemical reactions. Plants use them as defensive agents against predators (pests, insects, stress, etc.) and diseases. These commonly produced secondary metabolites exhibit high versatility in their properties (e.g., mode of toxicity, structure, chemical composition). Based on structures biosynthetic pathways, phytotoxins can be classified ribosome inactivating proteins, non-protein...
Aspergillus nidulans is a filamentous, ubiquitous and opportunistic pathogenic fungus, which causes fatal invasive aspergillosis among immunocompromised patients.As prelude to the investigations on possible control of human fungal diseases by selective targeting polyamines that are essential for growth development RNAi strategy, we have examined effect siRNA specific key polyamine biosynthesis gene ornithine decarboxylase (ODC) in vitro germinating spores A. assess ability RNA species induce...
