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.

The scaling down of technology in CMOS circuits, results in the down scaling of threshold voltage thereby increasing the sub-threshold leakage current. LECTOR is a technique for designing CMOS circuits in order to reduce the leakage current without affecting the dynamic power dissipation, which made LECTOR a better technique in leakage power reduction when compared to all other existing leakage...

This paper presents a new approach to building classifiers for Chinese character recognition. A new knowledge acquisition technique is used for building incrementally a knowledge based system f o r the classification task. The new knowledge acquisition technique is based on Ripple Down Rules, which is ay1 effective method for building large knowledge bases. We extended Ripple Down Rules to be a...

Performance prediction of checkpointing systems in the presence of failures is a well-studied research area. This paper makes three small contributions to this research area. First, we show how to apply the concept of availability from reliability theory as a useful metric for checkpointing systems. Second, we study the average availability of uniprocessor checkpointing systems, using the libck...

This study evaluated whether renal escape from vasopressin-induced antidiuresis is associated with alterations of vasopressin V2 receptor binding in the kidney inner medulla. A radioligand binding assay was developed using a novel iodinated vasopressin V2 receptor antagonist to analyze vasopressin V2 receptor binding in kidney inner medullary tissue from three groups of rats: normal rats mainta...
