Background: The primary aim of the current research was to explore the involvements of Muslim organizations in Nigeria particularly in the field of education and sports. The major problem was addressed that how much Muslim organizations working in Nigeria were contributing to education and provision of sports activities. Methods: This research employed a qualitative method. The eleven participants being administrative members of two organizations were declared as sample size. The tool used in the existing research contains interviews and documents analyses. Descriptive statistics and NVivo-10 both were employed to analyze the collected information as statistical approach. Results: Results of two Muslim organizations (Jama’atu Nasir Islam and NASFAT) showed which have made reliable and significant most especially in the field of education and sports. The existing study indicated that one of two organizations portrayed more quality activities of education and sports than the other. Conclusion: In summary, results of the research revealed that both Islamic organizations were aimed to uplift life standards of the community in Nigeria via promoting education and sports activities. These two of the organizations agreed to promote education and sports activities through building of new schools, converts to the religion of Islam, Financial assistance to needy, propagation of sports facilities, building of sports arenas, and Promotion of sports activities at grassroots level

LEADERSHIP STYLE DISCOVERY IN PERFORMANCE COACHING WITHIN SOCIAL CONTEXT

Background: The purpose of the existing research was to examine the relationships of leadership styles, coaching strategies, and social support with sport achievements of players. Methods: The study was used a correlation design. The population of the research was consisted of 830 female players of Islamia university of Bahawalpur and Government College University Faisalabad. The data was collected through survey questionnaires with sample size of 240 respondents. Adopted and modified questionnaires were employed with the permission of parent authors. Various statistical techniques were utilized on collected data for the purpose of data analyses. The descriptive statistics was used to measure the demographic information through mean, standard deviation, and percentages, whereas, Pearson’s correlation analysis and multiple regression analysis were employed to test the hypotheses. Results: The leadership styles, coaching strategies, and social support as predictors factors significantly influenced on the sport achievements of players. The findings revealed positive and highly significant relationships of leadership styles (autocratic and democratic), coaching strategies (social support and positive feedback), social support (parents, siblings, peers and sport teachers) with sport performance of players. Conclusion: Therefore, social support is also needed to players by their parents, siblings, peers, and sports teachers not only to get sport achievements but also for their appreciations either on their elite or worst performance. The implication of the existing research suggested that coaches as leaders should prepare the athletes utilizing their expertise and boost them with their coaching strategies as well to gain their achievement level best in sports

Antibiotic susceptibility patterns of Helicobacter pylori and triple therapy in a high-prevalence area

This study aims to determine primary Helicobacter pylori resistance and its effect on eradication of the organism. Ninety-two Patients with dyspeptic symptoms were enrolled. H. pylori was cultured and antibiotic sensitivity was determined by the Epsilometer test (Etest) for clarithromycin (CLR), amoxicillin (AMX) and metronidazole (MTR). 23S ribosomal RNA (rRNA) point mutations associated with clarithromycin resistance were also detected. Patients were treated with omeprazole (40 mg daily), CLR (500 mg) and AMX (1g twice a day) for 14 days. A (14)C-urea breath test ((14)C-UBT) was repeated four weeks after completion of treatment to confirm eradication. Triple therapy failure was seen in 30(33%) Patients. The resistance rates were: CLR 33% (30/92), MTR 48% (44192) and AMX (2/92). Clarithromycin resistance (CLR-R) was present in the 16-39 age group in 21 (47%) (P=0.007) compared to nine (19%)in the 40-79 age group. CLR resistance was seen in 30 H. pylori isolates, 20 (67%) from Patients with non-ulcer dyspepsia (NUD), six (20%) with gastric ulcer (GU) and four (13%) with duodenal ulcer (DU). Triple therapy failure was associated with CLR-R in 28 (93%) (

VGDRA: A Virtual Grid-Based Dynamic Routes Adjustment Scheme for Mobile Sink-Based Wireless Sensor Networks

In wireless sensor networks, exploiting the sink mobility has been considered as a good strategy to balance the nodes energy dissipation. Despite its numerous advantages, the data dissemination to the mobile sink is a challenging task for the resource constrained sensor nodes due to the dynamic network topology caused by the sink mobility. For efficient data delivery, nodes need to reconstruct their routes toward the latest location of the mobile sink, which undermines the energy conservation goal. In this paper, we present a virtual gridbased dynamic routes adjustment (VGDRA) scheme that aims to minimize the routes reconstruction cost of the sensor nodes while maintaining nearly optimal routes to the latest location of the mobile sink. We propose a set of communication rules that governs the routes reconstruction process thereby requiring only a limited number of nodes to readjust their data delivery routes toward the mobile sink. Simulation results demonstrate reduced routes reconstruction cost and improved network lifetime of the VGDRA scheme when compared with existing work

Comparison of the virulence markers of helicobacter pylori and their associated diseases in patients from Pakistan and Afghanistan

BACKGROUND/AIM: Helicobacter pylori is a Gram-negative bacteria, which is associated with development of gastroduodenal diseases. The prevalence of H. pylori and the virulence markers cytotoxin-associated gene A and E (cagA, cagE) and vacuolating-associated cytotoxin gene (vacA) alleles varies in different parts of the world. H. pylori virulence markers cagA, cagE, and vacA alleles in local and Afghan nationals with H. pylori-associated gastroduodenal diseases were studied. PATIENTS AND METHODS:Two hundred and ten patients with upper gastrointestinal symptoms and positive for H. pylori by the urease test and histology were included. One hundred and nineteen were local nationals and 91 were Afghans. The cagA, cagE, and vacA allelic status was determined by polymerase chain reaction. RESULTS:The nonulcer dyspepsia (NUD) was common in the Afghan patients (P = 0.025). In Afghan H. pylori strains, cagA was positive in 14 (82%) with gastric carcinoma (GC) compared with 29 (45%) with NUD (P = 0.006), whereas cagE was positive in 11 (65%) with GC and 4 (67%) with duodenal ulcer (DU) compared with 12 (18%) with NUD (P \u3c 0.001 and 0.021, respectively). The vacA s1a/b1was positive in 10 (59%) of GC compared with 20 (31%) in NUD (P = 0.033). In Pakistani strains, cagE was positive in 12 (60%) with GC, 7 (58%) with GU, 12 (60%) with DU compared with 11 (16%) with NUD (P \u3c 0.001, 0.004, and \u3c 0.001, respectively). In Pakistani strains, cagA/s1a/m1 was 39 (33%) compared with Afghans in 17 (19%) (P = 0.022). Moderate to severe mucosal inflammation was present in 51 (43%) Pakistani patients compared with 26 (28%) (P = 0.033) in Afghans. It was also associated with grade 1 lymphoid aggregate development in Pakistani patients 67 (56%) compared with 36 (40%) (P = 0.016) in Afghans. CONCLUSION: Distribution of H. pylori virulence marker cagE with DU was similar in Afghan and Pakistan H. pylori strains. Chronic active inflammation was significantly associated with Pakistani H. pylori strains

Risk factors associated with Helicobacter pylori infection treatment failure in a high prevalence area

Triple therapy is commonly used for the treatment of Helicobacter pylori infection. We determined risk factors associated with its failure in compliant Patients focusing on H. pylori density, virulence marker and 23S ribosomal RNA (rRNA) point mutations associated with clarithromycin resistance. H. pylori infection was diagnosed by (14)C urea breath test ((14)C UBT) and rapid urease test or histology. Triple therapy with esomeprazole 20 mg b.i.d., amoxicillin 1 g b.i.d. and clarithromycin 500 mg b.i.d. was prescribed for 10 days. 14C UBT was repeated 4 weeks after treatment. In total, 111 Patients [69 (62%) males] with a mean age of 46 +/- 16 years were enrolled. The mean age of treatment failure was 39 +/- 14 years compared to 48 +/- 16 years with eradication (P=0.002). Treatment failure was associated with younger mean age, point mutations in the 23S rRNA gene of H. pylori and vacA s1a and m1 when associated with cagA negativity
