MUSCLES ACTIVATIONS DURING "SHOULDER MOUNT" POLE ACROBATIC EXERCISE
No full textAuthor: Bc. Modinat Sanni Supervisor: Ing. Miroslav Vilímek, PhD Title: MUSCLES ACTIVATION DURING "SHOULDER MOUNT"POLE ACROBATIC EXERCISE Purpose: This study is an empirical - theoretical study presents the literature review regarding to the topic of the shoulder function anatomy, kinesiology, biomechanics, non-traumatic injuries of the shoulder and their prevention by using the available literatures. Further, the study also compares by surface electromyography the amplitudes, shapes and durations of myoelectric signals of m. latissimus dorsi, m. pectoralis maior, m. biceps brachii, m. infraspinatus and m. supraspinatus of dominant shoulder in two healthy individuals during acrobatic exercise on vertical pole known as "Shoulder Mount". The purpose was monitor the changes in two different conditions; i.e. kinesiotape and elbow brace and compare with the control condition for the reason of finding out their ability to affect the myoelectric activities of selected muscles. Further, the Shoulder Mount exercise had recorded by six Qualisys cameras for motion analyses. Methods and materials: The potentially eligible scientific articles perform a search of studies on the topic of kinesiotapes and tennis elbow brace as measured by EMG mainly on myoelectric activity of the shoulder complex were seared from..
The impact of the tax reform act of 1986 on the black population with particular reference to the individual income tax, 1987
No full textThe primary intent of this degree paper is to discuss some of the probable impact of the Tax Reform Act of 1986 on Blacks. An attempt has been made to show the economic status of the Black population and to explain the probable impact of the Tax Reform Act of 1986 on it. The old tax system had several shortcomings which prompted the need for tax reform. Among the several reasons for a new tax system were lack of efficiency and equity in the old system. Black politicians advocated more support for the equity side due to the disproportional distribution of the Black population, the distribution of income (majority of Black incomes are found in the lower income brackets and only about 20 percent of their income comes from property while majority of it comes from employment). Also, proportionally, more Black female head of households are found in that category (head of household) than White females. These circumstances would put the Black population in a position to bear more of the tax burden proportionally, than the White population. The major findings of the study were that (1) the restructuring of the tax rates could lower the progressivity of the tax system (this could probably have a disproportional adverse impact on the Black population), and (2) that the increase in the standard deduction and personal exemptions would probably compensate for this adverse impact on Blacks and other minority groups. It was concluded that the impact of the overall tax system on the tax burdens of the Black population, depends on the extent to which the system stresses progressive versus regressive taxes. There is still room for improvement and reform, and that through more research, income tax reforms can be made better. The main sources of information for this paper include The Atlanta Journal and Constitution, Consumer Reports, National Tax Journal, publications from the Bureau of the Census, and the Internal Revenue Service.

Kolaviron attenuates diclofenac-induced nephrotoxicity in male Wistar rats
No full textThe beneficial effects of kolaviron, a natural biflavonoid from the seeds of Garcinia kola, have been attributed to its antioxidant and anti-inflammatory activities. This study was designed to investigate the renoprotective effect of kolaviron in rat model of diclofenac (DFC)-induced acute renal failure. Thirty-five male Wistar rats were divided into seven groups of five rats each as follows: a control group that received propylene glycol orally and treatment groups that received diclofenac, diclofenac followed by kolaviron at three different doses and kolaviron only. Diclofenac treated rats showed sluggishness, illness and anorexia. Their urine contained appreciable protein, glucose and ketone bodies. Histopathological examination of their kidneys revealed profound acute tubular necrosis. Diclofenac treatment significantly increased levels of plasma creatinine, urea, sodium, chloride, potassium ions, and increased renal tissue activities of superoxide dismutase, catalase, levels of malondialdehyde and hydrogen peroxide. Fractional excretion of sodium and potassium and renal tissue levels of reduced glutathione and prostaglandin E2 (PGE2) decreased significantly in DFC treated groups. However, kolaviron administration significantly reduced toxic effect of DFC on PGE2 release, plasma levels of creatinine, urea, glucose, and electrolytes and significantly attenuated renal tubular and oxidative damages. Furthermore, the effects of DFC administration on food consumption, water intake, urine output and urine protein, glucose, ketone bodies and electrolytes, were significantly attenuated in animals treated with kolaviron. The results suggested that kolaviron ameliorated DFC-induced kidney injury in Wistar rats by decreasing renal oxidative damage and restoration of renal PGE2 release back to the basal levels.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
