delivery of exogenous materials such as nucleic acids, peptides, proteins, and drugs into cells is an important strategy in modern cellular and molecular biology. recently, the development of gene carriers for efficient gene transfer into cells has attracted a great attention. furthermore, lack of effective drug delivery is one of the major problems of cancer chemotherapy. many physical methods...
background and objective: staphylococcus aureus is an important infection in hemodialysis patients. we studied the prevalence of nasal carriage of methicillin-resistant staphylococcus aureus (mrsa) and its antibiotic resistance pattern in patients receiving hemodialysis as well as in dialysis unit staff. materials and methods: from june to september 2012, we evaluated 74 cases including 61 pati...
as one of the most important products of iran, pistachio has a significant share in non-oil revenues. its annual foreign exchange earnings are over 800 million dollars. however, production of this nut in the country’s major production centers is faced with many problems regarding the efficiency and productivity of the inputs. this study was performed by using two-stage cluster sampling method. ...
BACKGROUND A recent study showed that transforming growth factor-beta1 (TGF-beta1) induces amyloid-beta deposition in cerebral blood vessels and meninges of a transgenic mouse model of Alzheimer's disease (AD), and that TGF-beta1 mRNA levels are correlated with cerebral amyloid angiopathy (CAA) in human AD brains. A T/C polymorphism at codon 10 in exon 1 of the TGF-beta1 gene has been reported ...
Progranulin is a growth factor involved in the regulation of multiple processes including tumorigenesis, wound repair, development, and inflammation. The recent discovery that mutations in the gene encoding for progranulin (GRN) cause frontotemporal lobar degeneration (FTLD), and other neurodegenerative diseases leading to dementia, has brought renewed interest in progranulin and its functions ...
Auxin regulates several aspects of plant growth and development. Auxin is unique among plant hormones for exhibiting polar transport. Indole-3-acetic acid (IAA), the major form of auxin in higher plants, is a weak acid and its intercellular movement is facilitated by auxin influx and efflux carriers. Polarity of auxin movement is provided by asymmetric localization of auxin carriers (mainly PIN...
Energy carriers are addressed today as one of the main pillars of energy generation due to the increased growth of industries in developed and developing countries. According to the global view, increased consumption of energy carriers is causing an increase in the production of greenhouse gases, the global average temperature, and this, in turn, results in the quicker melting of ice in Antarct...
OBJECTIVE We examined whether the PPARgamma2 Ala12 allele influences growth in early life and whether this association is modified by breast-feeding. RESEARCH DESIGN AND METHODS This study was embedded in the Generation R Study, a prospective cohort study from early fetal life onward. PPARgamma2 was genotyped in DNA obtained from cord blood samples in 3,432 children. Information about breast-...
Lanthanum (La) is one of rare earth elements that was used as a crop growth stimulants; however, high concentration of La markedly inhibited plant growth. Our previous study indicated that, although La induced the expression of auxin biosynthesis-related genes, it markedly repressed primary root (PR) elongation by reducing auxin accumulation in PR tips. In this study, we exhibited that La reduc...
