Effects of Vibration vs. Resistive Exercise on Endothelial Function in Type 2 Diabetic Women Dr. Samah Alsaid Moawd

The main etiology for mortality and morbidity in patients with diabetes mellitus is atherosclerosis. A hypothesis for the initial lesion of atherosclerosis is endothelial dysfunction; which has been documented in patients with type 2 diabetes. Exercise is often recommended for patients with type 2 diabetes to improve physical conditioning and glycemic control. The aim of the current study was to investigate the effects of vibration exercise versus resistive training program on endothelial function, and glycemic control in T2DM.

Effect of whole-body vibration on muscle strength, spasticity, and motor performance in spastic diplegic cerebral palsy children Dr. Samah Alsaid Moawd
Spastic diplegia is a common form of cerebral palsy (CP) and is characterized by spasticity and muscle weakness of both lower limbs resulting in decreased walking ability. The purpose of this study was to evaluate the effect of whole body vibration (WBV) training on muscle strength, spasticity, and motor performance in spastic diplegic cerebral palsy children after 12-weeks treatment. ...
Impact of Whole Body Vibration Versus Aerobic Exercise Training in Modulation of Inflammatory Markers in Elderly Dr. Samah Alsaid Moawd
Aging is frequently characterized by an increase in systemic inflammation distinguished by elevated levels of pro-inflammatory cytokines. Increased levels of these inflammatory markers have been implicated in the pathogenesis of several diseases, including atherosclerosis, type 2 diabetes and rheumatoid arthritis (RA). The aim of the current study was to investigate the effects of vibration exercise versus aerobic training program on pro-inflammatory cytokines and C-reactive protein (CRP) in elderly. ...
Cardiac Troponin I Release Following A Single Aerobic Exercise Bout With Different Intensities In Adult Obese. Dr. Samah Alsaid Moawd

Elevated cardiac troponin I (cTnI) has been reported after exercise in healthy subjects. Currently, little is known about the impact of exercise intensity on cTnI release, but also the impact of obesity on this response. The purpose of this study was to investigate the influence of the intensity of a single bout of aerobic exercise on the post-exercise release of cTnI in obese adults

Cardiac autonomic neuropathy (CAN) as a result of diabetic autonomic neuropathy is positively related to a poor prognosis in diabetic patients. The aim of this study was to determine the effectiveness of moderate intensity aerobic exercise versus high eccentric strength training on heart rate variability in diabetic patients with CAN.

Effect of Over-Usage of Smart Phone in a Non-Neutral Neck Position on Respiratory Function in Female Adults Dr. Samah Alsaid Moawd
One of the most common sights we see these days is that of people with their smart phones. A boon for better communication, there has always been counter arguments and research over the increasing use of smart phones and its short-term and long-term health effects. Objective: To investigated the effect of over-usage of smart phones in a non-neutral neck position on cervical range of motion(CROM), spirometric values and maximal static pressures in young female adults ...
Physical Fitness and Physical Activity in Children and Adolescences with Type 2 Diabetes Dr. Samah Alsaid Moawd

The global obesity epidemic has raised concerns about the risk of Type 2 diabetes (T2DM) in childhood. The purpose of this study to compare motor performance and cardiorespiratory function in children and adolescences with type 2 diabetes against an age-matched control group.

Estimation of ultrasound reference values for the ulnar fascicular number and cross sectional area in young males, Medicine, Vol 96, Issue 10, 2017, IF 2.133 Pubmed عمرو عادل عبد الغني

To estimate the reference values for the number of fascicles and cross-sectional area (CSA) of the ulnar nerve at a single predetermined site by ultrasound in healthy young adult males. The demographic and physical characteristics of 50 adult male volunteers were evaluated and recorded. The subjects were positioned supine with the elbow flexed at 90° and the palm of the hand placed on a hard surface. The ulnar nerve was scanned bilaterally 1 cm proximal to the medial epicondyle in projection of the cubital tunnel. The number of fascicles and mean CSA of the ulnar nerve were identified. In addition, the side-to-side differences of the estimated reference values and their correlations with the age, weight, height, and body mass index (BMI) were evaluated. The mean fascicular number was 5.66±1.48, the mean ultrasound-estimated CSA of the ulnar nerve was 6.54±1.67mm2 and AQ4 both sides were comparable in the mean CSA and fascicular number (6.43±1.80mm2 and 5.88 vs 6.64±1.55mm2 and 5.44, for right and left side, respectively). No significant correlations were observed between CSA and fascicles number and age, weight, height, or BMI of study subjects. The reference values for the number of fascicles number and the CSA of the ulnar nerve at a single predetermined site were identified. These values could be used for the sonographic diagnosis and follow-up of the ulnar nerve lesions.

Endocytosis rate increase provoked by bipolar asymmetric electric pulses عمرو عادل عبد الغني

It has been reported that electric and electromagnetic pulses can increase the endocytotic rate, showing either an all-or-nothing response above a threshold of the field strength or linear responses as a function of the field strength and the treatment duration – using bipolar symmetrical pulses and monopolar pulses, respectively. We have investigated the reasons of such a discrepancy. To this end, cells were suspended in either low conductive or physiologically conductive medium, and exposed to bipolar asymmetric electric pulses (EPs) for different exposure times (2 to 20 min). These EPs had low amplitude (5.7 to 18 V/cm) with a duration varying from 100 to 500 μs and a frequency of 100 to 500 Hz. The effects of these parameters on cell viability and field-induced uptake of molecules were analyzed by spectrofluorometric measurements using either the fluorescent dye Lucifer Yellow (LY) or BSA-FITC. The former acted as an indicator molecule for the fluid-phase endocytosis and the latter for detecting receptor-mediated endocytosis. An increase of 1.3 to 1.5-fold in the fluid-phase and receptor-mediated endocytosis rate was observed using the physiologically conductive medium (10 mS/cm). This increase was an all-or-nothing type of response that occurred above a threshold value of the electric field intensity (between 9.3 and 9.8 V/cm). Variations of the repetition frequency or pulse duration did not modify this threshold. The observed increase in either LY or BSA-FITC uptake was not a thermal effect. We examined electric pulses different from that previously published by other researchers to answer the question of...

Exponentially Decaying Electric Pulses for Improving Radioactive Iodine uptake in human thyroid cancer cells عمرو عادل عبد الغني
Radioactive iodine (radioiodine) is an effective nuclear medicine treatment used to eradicate thyroid cancer cells. The problem was the inability of thyroid cells to retain radioiodine which causes the thyroid cancer cells to be resistant to radioactive iodine treatment. Therefore, there are different methods that have been established to enhance the radioiodine uptake within the thyroid cancer cells for therapeutic purposes. Exposure of human cells to exponentially decaying high intensity, short duration electric pulses permeabilizes the plasma membrane to impermeable molecules. Electroporation is a physical modality that involves high intensity, short duration electric pulses to facilitate the entry of impermeable molecules by increasing the plasma membrane permeability. The purpose of this study was to use exponentially decaying high intensity, short duration electric pulses in incorporating radioactive iodine into non-iodine retaining follicular thyroid carcinoma cell line FTC133. Results showed that the uptake of radioiodine by electroporation has a dependence on the electric field, external concentration of the iodine, time and the temperature of incubation. The incorporated radioiodine was retained over a period of 24 h. The permanent concentration of the incorporated iodine may have a significant effect on the tumoricidal properties if approved in vivo. ...
