Focal thickening of the calvarium, hypoplasia of the white matter, cortical calcifications, and a leptomeningeal drape that enhanced after contrast injection were demonstrated by MR in the parietooccipital region ipsilateral to a facial sebaceous nevus in a patient with epidermal nevus syndrome.
We report a case of the Antley-Bixler syndrome in an 11-year-old girl. She presented with bilateral proximal femoral focal deficiency, right clubfoot, left radiohumeral synostosis, bilateral ear hypoplasia, cleft palate, tongue tie, missing teeth, congenital heart disease, a pelvic kidney with hydronephrosis, and mental retardation. Proximal femoral focal deficiency has never been reported befo...
Fibroblasts play a pivotal role in the process of cutaneous wound repair, whereas their migratory ability under diabetic conditions is markedly reduced. In this study, we investigated the effect of basic fibroblast growth factor (bFGF) on human dermal fibroblast migration in a high-glucose environment. bFGF significantly increased dermal fibroblast migration by increasing the percentage of fibr...
Cartilage hair hypoplasia (CHH), is a rare cause of metaphyseal chondrodysplasia and short stature. Other features included hair abnormality, immunodeficiency, anemia, gastrointestinal disorders (Hirschsprung disease, celiac, …) and increased risk of cancer. The disease is an autosomal recessive disorder and previously has not been reported in Iran. We report a 9-year-old boy diagnosed as car...
Focal facial dermal dysplasias (FFDDs) are rare genetic/developmental disorders characterised by bilateral 'scar-like' facial lesions. Four subtypes are classified by the bitemporal (FFDD1-3) or preauricular (FFDD4) lesion location. FFDD1-3 are differentiated by additional facial abnormalities and inheritance patterns. Although the genetic defects causing FFDD1 and FFDD2 remain unknown, recent ...
Neurofibromatosis 1 (NF1) is a tumour suppressor gene syndrome characterized by multiple cutaneous and plexiform neurofibromas. Focal osseous abnormalities, short stature, and decreased bone mineral density are also frequent in people with NF1. We measured serum 25-hydroxyvitamin D concentrations in 55 patients with NF1 and 58 healthy controls, and correlated the findings in the patients with N...
Cerebellar hypoplasia and hydrocephalus were identified in day old broiler chickens showing nervous signs, impaired mobility, and diarrhea. At postmortem examination, brains of chickens were misshapen and cerebellums were smaller than normal. Microscopically, cerebellar folia were reduced in size and irregularly shaped, and the ventricles were widely distended. Affected cerebellums had focal ar...
The in situ regeneration of reduced nicotinamide cofactors (NAD(P)H) is necessary for practical synthesis of many important chemicals. Here, we report the engineering of a highly stable and active mutant phosphite dehydrogenase (12x-A176R PTDH) from Pseudomonas stutzeri and evaluation of its potential as an effective NADPH regeneration system in an enzyme membrane reactor. Two practically impor...
NAD+-dependent formate dehydrogenase (EC 1.2.1.2, FDH) from methylotrophic bacterium Pseudomonas sp.101 exhibits the highest stability among the similar type enzymes studied. To obtain further increase in the thermal stability of FDH we used one of general approaches based on hydrophobization of protein alpha-helices. Five serine residues in positions 131, 160, 168, 184 and 228 were selected fo...
A glutathione (GSH)-dependent pathway is used for formaldehyde metabolism by a wide variety of prokaryotes and eukaryotes. In this pathway, S-hydroxymethylglutathione, produced by the reaction of formaldehyde with the thiolate moiety of glutathione, is the substrate for a GSH-dependent formaldehyde dehydrogenase (GSH-FDH). While expression of GSH-FDH often increases in the presence of metabolic...
