background and purpose: microorganism-based synthesis of nanostructures has recently been noted as a green method for the sustainable development of nanotechnology. nowadays, there have been numerous studies on the emerging resistant pathogenic bacteria and fungal isolates, the probable inability of bacteria and fungi to develop resistance against silver nanoparticles’ (snps) antibacterial, ant...

The most distinctive feature of the human pathogenic fungus is a polysaccharide capsule that is essential for virulence and is composed primarily of glucuronoxylomannan (GXM) and galactoxylomannan (GalXM). GXM mediates multiple deleterious effects on host immune function, yet relatively little is known about its physical properties. The average mass of Cryptococcus neoformans GXM from four anti...

PURPOSE To investigate the role of SPARC in the regulation of the expression and deposition of extracellular matrix (ECM) proteins in the lens capsule. METHODS Wild-type (SP+/+) and SPARC-null (SP-/-) mice of embryonic day (E)14 to 3 months of age were examined. Transcript levels of lens basement membrane (BM) components were analyzed by semiquantitative RT-PCR with mRNA from lens epithelia. ...

Lens fibre differentiation is a life-long process related with lens transparency, and is particularly intense during development, being related with an FGF-2 antero-posterior gradient at the equator level as the main growth factor involved which has been related with the basal membrane of the lens anlagen known as “Lens capsule”. However the lens fibre differentiation induced by FGF2 depends, a...

PURPOSE Anterior subcapsular cataracts are characterized by the appearance of opaque plaques of abnormal cells. Distinctive spindle-shaped cells containing alpha-smooth muscle actin are present and are associated with wrinkling of the overlying lens capsule. Accumulations of extracellular matrix, including type I collagen, also are found. The authors previously reported that transforming growth...

Phalaenopsis is an important genus of orchids that is grown for economical production of cut flower and potted plants. The objective of this study is the evaluation of correlation between morphological and physiological traits of self and cross-pollination of 5 varieties of Phalaenopsis orchid. Some morphological traits were measured: Capsule length (CL), capsule volume (CV), weight of seeds in...

Group A streptococci control expression of key virulence determinants via the two-component sensorregulator system CsrRCsrS. The membrane-bound sensor CsrS is thought to respond to previously unknown environmental signal(s) by controlling phosphorylation of its cognate regulator component CsrR. Phosphorylation of CsrR increases its affinity for binding to the promoter regions of Csr-regulated g...

results migration of cells started on the fifth day. as a result of this migration, most cells were located on the surface of the scaffold and formed epiderm-like structure and some penetrated into the scaffold. by day 25, cells which had penetrated into the scaffold had various destinies such as becoming elongated spindle-shaped cells and creating blood vessel-like structures. conclusions adm ...

background: extracellular vesicles are particles ranged from 30 nm to 5µm and subcategorized into three groups; exosomes, microvesicles and apoptotic bodies, each of which have different biological impact. lack of a standard method for the detection and isolation of mvs has led to a challenging issue that is a worth considering. in this study, we isolated mvs from the conditioned medium of uc-m...
