A new method was developed for simultaneous determination of copper, lead, and cadmium, based on their voltammetric response at a carbon paste electrode modified with hexagonal mesoporous silica (HMS) immobilized quercetin (HMS-Qu/CPE). Compared with quercetin modified carbon paste electrode (Qu/CPE) and quercetin ionic liquid modified carbon paste electrode (Qu-IL/CPE), the HMS-Qu/CPE exhibite...

We compared the electrophysiological responses to serotonin (5-HT) of neonatal and juvenile rat hypoglossal motoneurons (HMs) by using intracellular recording techniques in a brainstem slice preparation. In neonatal HMs (</=P8), 5-HT caused a substantial decrease in the amplitude of spike afterhyperpolarization (AHP) that was associated with an increase in the minimal repetitive firing frequenc...

This paper presents a modeling application of surface runoff using the Hydrologic Modelling System (HEC-HMS). A case study was carried out for the Jianghe watershed, a typical semi-arid and sub-humid geo-climatic region in northern China. Two modeling schemes using different descriptive sub-mechanism models provided by HEC-HMS for runoff volume, direct runoff and routing (channel flow) were inv...

In this chapter, we present the design of Teacher (an acronym for TEchniques for the Automated Creation of HEuRistics), a system for learning and for generalizing heuristics used in problem solving. Our system learns knowledge-lean heuristics whose performance is measured statistically. The objective of the design process is to nd, under resource constraints, improved heuristic methods (HMs) as...

Twenty three hydatidiform moles (HMs) were studied using the techniques of "RFLPs" employing a minisatellite deoxyribonucleic acid probe. Among the 23 HMs, 17 were homozygous types resulting from a duplicated haploid sperm, and two were heterozygous types resulting from fertilization two independent sperms (dispermy). It was revealed that the four histopathologically diagnosed complete HMs (CHM...

A little-appreciated association between renal cell carcinoma (RCC) and hematologic malignancies (HMs) has been reported for at least 20 years. The HM characteristically occurs first in patients with both neoplasms, and the large majority (94%) of these HMs are of B-cell origin. Furthermore, the majority of patients with RCC and an HM are male. Recently, we have noted an increased incidence of ...

Incubation of human leukocytes with dehydroascorbate (DHA) results in an increase in their reduced ascorbate (AA) content and hexose monophosphate shunt (HMS) activity, independent of oxygen supply. Incubation with AA induces these changes only in the presence of oxygen. The increase in HMS activity observed as cell AA increases by 1 micromol is the same during incubation with either DHA or AA....

Malaria is endemic in the North of Brazil. However, Hyperreactive Malarious Splenomegaly (HMS) has been rarely described. Splenomegaly in HIV/Aids infection has a large differential diagnosis, but malaria is a cause of gross splenomegaly, regardless of the HIV status. In this paper, we report the case of a 50-year-old man, HIV positive, with massive splenomegaly and multiple malaria infections ...

OBJECTIVE To provide data on herbal medicine (HM) use and safety in patients attending a nephrology clinic at Sheikh Khalifa Medical City (SKMC), Abu Dhabi, United Arab Emirates (UAE). METHODS A prospective, 3-month study between June and September 2007, investigated all patients presenting to the Nephrology Clinic of the Sheikh Khalifa Medical center (SKMC) in Abu Dhabi, UAE. A structured qu...

Thyroxine-induced epilepsy is a very rare condition occurring in epileptic patients. Here we report a boy with thyroxine-induced hypermotor seizure (HMS) following thyroxine administration for his central hypothyroidism secondary to surgery and cranial radiation for his brain tumor. After 3 years seizure-free period, he had repeated HMS, seven to eight attacks per day, after initiation L-thyrox...
