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..
Combined but not single administration of vitamin C and<scp>l</scp>-carnitine ameliorates cisplatin-induced gastric mucosa damage in male rats
No full textAlthough cisplatin is a potent anticancer drug, it instigates oxidative and pro-inflammatory reactions that pose significant and distressing clinical symptoms. Therefore, this study investigated the effects of vitamin C and (or) l-carnitine on cisplatin-induced gastric mucosa damage in rat. The rats were allocated into 6 groups (n = 5). The control group received distilled water, while the treatment groups received cisplatin alone (CIP), or cisplatin with vitamin C, l-carnitine, or their combination. Cisplatin caused disruption of the gastric mucosa histoarchitecture and altered the mucus barrier function. Moreover, the stomach tissue of the CIP-treated group showed increased levels of oxidative stress markers (malondialdehyde and H2O2) and decreased activities of antioxidant (superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase) and non-antioxidant (reduced glutathione) enzymes. These deleterious events were accompanied with significant increases in pro-inflammatory cytokines and inflammatory infiltration markers, myeloperoxidase and inducible nitric oxide synthase. However, the administration of both vitamin C and l-carnitine, and not either of the two showed additive effects in attenuating the adverse effects of cisplatin. The histological results agreed with the biochemical assays. The study concluded that the combined administration of vitamin C and l-carnitine, but not the single therapy, could prevent the adverse effects of cisplatin on gastric tissue.</jats:p
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.

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.

.) Leaf on Aspirin-Induced Gastric Ulceration and Oxidative Mucosal Damage in a Rat Model of Gastric Injury
No full textProtective Effects of Methanol Extract of (.) Leaf on Aspirin-Induced Gastric Ulceration and Oxidative Mucosal Damage in a Rat Model of Gastric Injury
No full textThis study investigated the quantitative polyphenolic constituents and gastroprotective effects of methanol extract of Vernonia amygdalina leaf (MEVA) against aspirin-induced gastric ulcer in rats. Ulceration was induced by 3 days’ oral administration of aspirin (150 mg/kg body weight). Wistar rats were pretreated with cimetidine (reference drug) at a dose of 100 mg/kg body weight and MEVA at 200, 300, and 400 mg/kg body weight once daily for 28 days prior to ulcer induction. At the end of the experiment, gastric secretions, antioxidant status, and histopathological alteration were evaluated. We observed that the significantly increased ulcer index, gastric volume, free and total acidity, malondialdehyde level, and pepsin activity were effectively reduced following treatment with 200 and 300 mg/kg MEVA. The extract also markedly attenuated the reduced activity of superoxide dismutase and reduced glutathione level as well as pH and mucin content in the ulcerated rats. Administration of the extract also significantly attenuates necrosis of the stomach tissue of the ulcerated rats. The results suggested that the MEVA leaf, preferably at 200 and 300 mg/kg body weight, ameliorated aspirin-induced gastric ulceration via antioxidative and H 2 receptor antagonist

No full textTHE EFFECT OF NEWBOULDIA LAEVIS ON WISTAR RAT’S TESTIS AND LIVER HISTOMORPHOLOGY IN CADMIUM-INDUCED TESTICULAR TOXICITY AND HEPATOTOXICITY
No full textNewbouldia laevis is a plant known for its great
nutritional and medicinal importance with antimicrobial, antibacterial,
anti-inflammatory, anti-malarial, anti-coagulant, anti-diabetic and antioxidant properties. Cadmium is globally acknowledged as an
environmental intoxicant with widespread toxicity on the biological
system. Thus this work was carried out to evaluate the protective role
of Newbouldia laevis aqueous leaf extract on the wistar rat testis and
liver histomorphology in cadmium-induced testicular toxicity and
hepatotoxicity. Methodology: This experimental study was carried out
on 25 male adult wistar rats. The animals were divided into 5 groups of
5 animals each – Control, Cadmium, Newbouldia laevis, Coadministration and Pre/Post Treatment Groups. The Treatment Groups
received 1.2mg/kg body weight of cadmium, 200mg/kg body weight of Newbouldia laevis,
1.2mg/kg body weight of cadmium + 200mg/kg body weight of Newbouldia laevis
simultaneously and 1.2mg/kg body weight of cadmium for two weeks and 200mg/kg body
weight of Newbouldia laevis for two weeks. Results: The exposure of experimental animals
to cadmium showed deleterious effects on the organs of study (testes and liver). Treatment
with aqueous extract of Newbouldia laevis revealed varying degrees of restoration after hepatotoxicity by cadmium. However, Newbouldia laevis was unable to ameliorate the
testicular damage occasioned by cadmium as cellular disruptions were still evident even with
its administration. Conclusion: The present study suggests that the oral administration of
aqueous leaf extracts of Newbouldia laevis can be used to manage hepatotoxicity but not
testicular toxicit
