The Erdenet mining and processing facility (Mongolia) develops a large copper-molybdenum deposit. volume of waste in the tailings dump enterprise reaches 600 m. m 3 its area is more than 1300 hectares. Quarries pits release significant amounts persistent pollutants into environment. They penetrate groundwater surface water also spread as dust. results comprehensive geochemical geoecological stu...

Contagious agalactia (CA) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. Mycoplasma (M.) agalactiae is the main cause of the disease in sheep and goats. The aim of the present study was to detect M. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or witho...

In this review article, liposome a novel drug delivery has been discussed, which is one among the various system used to target particular tissue. As structural similarity between lipid bilayer and cell membrane, can easily penetrate produce an effective of such that free would not able penetrate. Some other systems include niosomes, microparticles, resealed erythrocytes, pharmacosomes, etc. Th...

Abstract Dimension stone is natural rock prepared for building use. It rapidly colonised by microorganisms that cause discoloration (mainly cyanobacteria, algae and fungi) structural damage. Microbial mobilisation of ions leads to new superficial or internal deposits, weakening the structure. Cyanobacteria fungi may penetrate, filling pores creating spaces. Lichens, fungus/phototroph associatio...

Needle stick injuries are a common event in the healthcare setting. When drawing blood, administering an intramuscular or intravenous drug, performing other procedures involving sharps, needle can slip and injure worker. This sets stage to transmit viruses from source person recipient. These also commonly occur during recapping as result of failure place used needles approved sharps containers....

Alzheimer's disease (AD) is an infectious disease caused by spirochetes, and these spirochetes form biofilms, which attract the innate immune system. The innate immune system first responder, Toll-like receptor 2, generates both NF-κB and TNF-α which try to kill the spirochetes in the biofilm, but cannot penetrate the "slime". NF-κB is also responsible for the generation of amyloid-β (Aβ) which...

Topical acyclovir (ACV) in polyethylene glycol (PEG) ointment has been disappointing in the treatment of recurrent herpes simplex virus infections in immunocompetent patients. To investigate the possible role of poor drug delivery from this formulation, we studied the penetration of ACV through excised human skin from three vehicles; PEG ointment, modified aqueous cream, and dimethyl sulfoxide....

Tuberculosis can be caused by a number of different, but closely related, bacteria. Members of the tuberculosis complex include Mycobacterium (M.) tuberculosis, M. bovis and M. microti. M. tuberculosis causes over 90% of tuberculosis in man, but rarely infects other mammals, except for dogs. M. bovis is the main cause of tuberculosis in cattle. It can also infect various other mammals, includin...
