The effect of an addition of 0.37 Wt % Won the overall transformation rate of the austenitepearlite reaction in a eutectoid steel is examined. Pearlite growth rates and interlamerllar spacing are measured as a function of transformation temperatures. Tungesten raises the Ael temperature, for most transformation temperatures, decreases the overall reaction rate, the growth rate and the interlame...

UNLABELLED Thermoregulation interacts with cardiovascular regulation within the central nervous system. We therefore evaluated the effects of head-down tilt on intraoperative thermal and cardiovascular regulation. Thirty-two patients undergoing lower-abdominal surgery were randomly assigned to the 1) supine, 2) 15 degrees -20 degrees head-down tilt, 3) leg-up, or 4) combination of leg-up and he...

background:  pericardial effusion (pe) in down syndrome (ds) patients  usually occur s   secondary to hypothyroidism,  but  we have   no  report of massive pericardial effusion in   euthyroid   down syndrome patient with  supravalvar  pulmonary stenosis . case presentation:  we  report ed   an   11-month-old  male with down syndrome   with  massive  pericardial  effusion that  had conservative ...

Insulin can stimulate the expression of c-fos and other immediate early genes in many insulin-sensitive cell types. We found previously that this effect of insulin was essentially normal in cells in which protein kinase C (PKC) was down-regulated by 16 h of exposure to 16 microM phorbol 12-myristate 13-acetate (PMA). However, recent studies by other groups have suggested that much of the insuli...

The inducible transcriptional complex AP-1, composed of c-Fos and c-Jun proteins, is crucial for cell adaptation to many environmental changes. While its mechanisms of activation have been extensively studied, how its activity is restrained is poorly understood. We report here that lysine 265 of c-Fos is conjugated by the peptidic posttranslational modifiers SUMO-1, SUMO-2, and SUMO-3 and that ...

keratoderma is a group of disorders characterized by abnormal thickening of skin. acquired palmar keratoderma has many underlying causes. the association of thyroid disease and palmar keratoderma rarely reported. hypothyroidism, although very rare association, must be suspected in patients with acquired ppk, particularly when it occurs in setting of systemic symptoms or predisposing conditions....

conclusions the current study indicated that h. pylori infection occurs at a higher rate in patients with down syndrome and mental retardation. this may provide more reasons to control the transmission of h. pylori among them. results the differences between the groups were compared by t-test and x2 test. seropositivity for h. pylori was significantly higher in patients with down syndrome and m...

we report three cases of asymptomatic celiac disease identified in children with down syndrome after being screened at around twenty-four months of age.  these cases raise the question as to what age is screening for celiac disease indicated in a child with down syndrome and no symptoms.
