mccune-albright syndrome (mas) is a rare, heterogenous, clinical condition caused by a rare genetic mutation. the disorder is more common in females and is characterized by a triad of cutaneous, bone and endocrine abnormalities.  we describe a girl patient with mas having precocious puberty and multiple cafe-au-lait macules and deforming polyostotic fibrous dysplasia of bone. clinical presentat...

Rat T-kininogen has been separated into two molecular variants by affinity chromatography on concanavalin A (ConA): a ConA-reactive (ConA+) and a ConA-non-reactive (ConA-) fraction, from which carbohydrate chains were quantitatively released by hydrazinolysis. On the basis of high-resolution 400 MHz 1H-n.m.r. spectroscopy of the re-N-acetylated hydrazinolysates, the carbohydrate structures of t...

Various terms have been suggested to describe non-ossifying fibroma including fibrous cortical defect, cortical desmoid, metaphyseal fibrous defect and non-osteogenic fibroma. Regardless of the term used, they probable all refer to abnormal osteoclastogenesis at the metaphyseal region. Non-ossifying fibroma is a benign fibrogenic tumor primarily affecting children and adolescents. It is the mos...

This study systematically investigates the role of graphene oxide (GO) and reduced GO (rGO)/silk-based composite micro/nano-fibrous scaffolds in regulating neuronal cell behavior vitro, given limited comparative studies on effects family materials nerve regeneration. Fibrous can mimic architecture native extracellular matrix are potential candidates for tissue engineering peripheral nerves. Sil...

Development of cotton (Gossypium hirsutum L.) squares (i.e. floral buds with bracts) is fundamental for yield formation. A 2-year field study was conducted to determine dry weight (DW) accumulations of cotton leaves, floral bracts and floral buds, and the changes in concentrations of non-structural carbohydrates (hexoses, sucrose and starch) in these tissues during square ontogeny as affected b...

Many carbohydrate-binding proteins contain aromatic amino acid residues in their binding sites. These residues interact with carbohydrates in a stacking geometry via CH/π interactions. These interactions can be found in carbohydrate-binding proteins, including lectins, enzymes and carbohydrate transporters. Besides this, many non-protein aromatic molecules (natural as well as artificial) can bi...

In woody plants, pioneer roots are the main roots used to expand the root system horizontally and vertically whereas fibrous 'feeder' roots are chiefly used in the absorption of water and nutrients. Because of their different roles, we expected newly emerged pioneer and fibrous roots to respond differently to restrictions in soil moisture. We hypothesized that fibrous roots would exhibit greate...

This study was carried out to determine the chemical composition and estimation of nutritive value of apple pomace (AP) by-product using in vitro gas production technique. Fermentation of AP samples were carried out with rumen fluid obtained from three mature canulated steers. The samples were collected from SanSan Shahd factory in Urmia, Iran. The amount of gas production for AP at 2, 4, 6, 8,...

AIM Doege-Potter syndrome is a rare condition consisting of a mesenchymal tumor, either benign or malignant, accompanied by severe hypoglycemia. The syndrome was first described independently by two American physicians, Karl Walter Doege (1867-1932) and Roy Pilling Potter (1879-1968), in 1930, but it was not before 1988 that it was associated with non-islet cell tumor production of insulin grow...
