in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

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 ...

One important challenge of microsystems design is the implementation of miniaturized actuation principles efficient at the micro-scale. Shape Memory Alloys have early on been considered as a potential solution to this problem as these materials offer attractive properties like a high-power to weight ratio, large deformation and the capability to be processed at the microscale. This paper review...

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...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...

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...

Objective Determine the effects of hyoid myotomy and suspension (HMS) without concurrent palatal or tongue base sleep surgery for obstructive sleep apnea (OSA). Method Patients with OSA treated with HMS were identified using CPT code (21685) at an academic and private sleep surgery clinic. Those who underwent concurrent palatal or tongue base sleep surgery were excluded. Outcomes included sim...
