Collision and turnover are fatal to mobile robots. Control methods are suggested for solving the fatal problems of mobile robots maneuvered by an operator. Speed reduction and wall following are applied for collision avoidance using ultrasonic sensor data. Modified Hough transform is suggested to obtain a wall model from sonar data overcoming limitations of ultrasonic sensors. The robot is also...

Acid-sensing ion channel 1 (ASIC1) is a newly characterized contributor to store-operated Ca(2+) entry (SOCE) in pulmonary vascular smooth muscle (VSM). Since SOCE is implicated in elevated basal VSM intracellular Ca(2+) concentration ([Ca(2+)](i)) and augmented vasoconstriction in chronic hypoxia (CH)-induced pulmonary hypertension, we hypothesized that ASIC1 contributes to these responses. To...

We assessed different systolic cardiac indices to detect left and right ventricular systolic dysfunction in cirrhotic patients before liver transplantation. Between 2010-2011, 81 consecutive individuals with confirmed hepatic cirrhosis who were a candidate for liver transplantation were enrolled in this study. A total of 32 age and sex matched healthy volunteers were also selected as the contro...

Inactive renin in rat arterial walls was investigated according to the following experiments. Dialysis at pH 7.4 following dialysis at pH 3.3 of the arterial tissue resulted in a significant rise of renin activity, from a control value of 0.41 +/- 0.07 to 0.62 +/- 0.06 ng/ml/h (p less than 0.01). Treatment with trypsin of the arterial tissue caused a rapid and apparent increase in the renin act...

background: this two-arm, randomized clinical study aimed to compare efficacy between topical alpha ointment and topical hydrocortisone cream (1%) in the healing of radiation-induced dermatitis in breast cancer patients. methods: the inclusion criteria comprised newly pathologically proven, locally advanced breast cancer (treated with modified radical mastectomy followed by sequential adjuvant ...

Increasing interest in multiple strain Bacillus probiotics and parietal yeast fractions as feed ingredients for egg laying hen diets has also led to food safety questions. This study was undertaken evaluate the ability of these products reduce Salmonella Enteritidis colonization. Sixty Hy-Line hens aged 56 weeks were placed individual cages fed a mash diet containing one following treatments, c...

This paper discusses the results of the analysis of the relationship between dose and solid cancer incidence among nuclear workers (males) who worked as liquidators after the Chernobyl accident. Information on this cohort of individuals is available at the regional center of Russian National Medical and Dosimetric Registry operating at the RF State Research Centre-Institute of Biophysics. Medic...

background: in intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. this study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

Background: 1, 2-Dimethylhydrazine (DMH) enhances lipid peroxidation rate by tumor mitochondria than normal tissue counterpart and causes many disorders in antioxidant system in liver. It also increases the level of enzymes that metabolize toxin in liver and colon. The aim of this study was to evaluate the alteration of liver and its enzymes after DMH injection and evaluate protective effect of...
