Purpose: In the present study the effect of BMP-6 was investigated on chondrogenesis of adiposederived stem cells. Materials and Methods: Mesenchymal stem cells derived from subcutaneous adipose tissue were cultured on alginate scaffold to induce chondrogenesis in experimental group, with chondrogenic medium having BMP-6 growth factor for 3 weeks. In control group medium without BMP-6 was appli...
Background & Objectives: Shiga toxin-producing Escherichia coli (STEC) O157:H7 have emerged as pathogens that can cause food-borne infections and severe and potentially fatal illnesses in humans. E.coli O157:H7 colonizes the digestive tract of cattle and is transmitted to humans by food and water. The objectives of this study were to characterize the prevalence of E.coli O157:H7 isolates in ham...
Magnetic nanoparticles can bind to different drug delivery systems and can be used for drug targeting to a specific organ by using an external magnetic field as well as used in hyperthermia by heating in alternating magnetic fields. The characteristics of iron oxide nanoparticles are significantly affected by particle size, shape and zeta potential, among which the particle size plays the most ...
Existing research on Smallto Medium-sized Manufacturers (SMMs) pays scant attention to factors affecting their growth in the contact of paradigms of competition and, particularly, segments of the supply chain in which they operate. This work adopts a supply chain perspective to propose a business definition and model for the process of the SMMs understanding of, responding to, andinf1uencing cu...
The reliability of the Mycobacteria Growth Indicator Tube (MGIT) 960 system for rapid detection of mycobacteria in clinical specimens was evaluated and compared to the radiometric method (BACTEC 460TB) and to mycobacterial culture on Lowenstein-Jensen (LJ) medium. Clinical specimens (n = 590) were tested without selection. A total of 121 (20.5%) isolates of mycobacteria were recovered; 98 (81.0...
Low glucose condition induces neuronal cell-death via intracellular mechanisms including mitogen-activated protein kinases (MAPK) signaling pathways. It has been shown that low glucose medium decreases neuronal survival in cerebellar granule neurons (CGNs). In this study, we have examined the activation of JNK, p38kinase and ERK1/2 pathways in low glucose medium in CGNs. The CGNs were prepared ...
a 21-year old man presented with a 2-month history of a persistent ulcerated plaque on his right hand with no further lesion elsewhere. he was in contact with decorative aquarium in his hobbies associated with fish and water exposure. on physical examination there was a 2×2cm erythematous plaque with central ulceration on the thumb. there was no regional lymphadenopathy or similar lesion elsewh...
