Open Journal of Veterinary Medicine 2024年第2期14卷 11-20页

作者： ahmed mohamed ahmed Sumaya Hassan Ali Abdisalam mohamed Ali Abdirazack Saleban Osman Binti Abubakar mohamed Abdifatah Mohamud Ibar Shafii Abdullahi mohamed mohamed Abdelrahman mohamed ahmed Ali Omar Zakaria Ibrahim Issack College of Veterinary Medicine Abrar University Mogadishu Somalia Faculty of Veterinary Medicine and Animal Husbandry Somali National University Mogadishu Somalia Faculty of Veterinary Science Benadir University Mogadishu Somalia

Contagious bovine Pleuropneumonia (CBPP) is an infectious and highly contagious respiratory disease of cattle and water buffalo, caused by the Mycoplasma mycoides subspecies mycoides. It induces significant economic losses and leads to a severe livestock production problem, negatively influencing people’s livelihoods of affected countries. In Somalia, there is no updated data on the prevalence and distribution of the disease. Hence, a descriptive cross-sectional study was conducted from September 2022 to June 2023 in different villages under the Afgoye District of lower Shabelle region, Somalia. The main purpose of this study is to assess the sero-prevalence and identify the associated risk factors for the occurrence of the disease. In this study, villages, age, sex, breed, and body condition were considered as risk factors. A total of 90 blood samples were collected and tested in the laboratory using the Anti-CBPP Elisa kit test. Out of 90 serum samples from herd cattle, 32 were positive, resulting in an overall prevalence of 35.5%. In addition, we found a statistically significant variation between the prevalence of the disease and factors such as sex, age, body condition and breeds. In summary, the overall prevalence of Contagious bovine pleuropneumonia in this study area is worth to be considered because there is a low quality of health care and less awareness of the Contagious bovine Pleuropneumonia effects on herds, which warrants the official authorities to act and follow appropriate preventive and control measures to reduce the incidence of the disease and generate appropriate controlling and prevention measures in all regions of Somalia.

Magnetoresistive properties of Ni-doped La_(0.7)Sr_(0.3)MnO_3 manganites

Rare Metals 2016年第7期35卷 551-558页

Lao.7Sr0.3Mnl_xNixO3 （x = 0, 0.025, 0.050 and 0.075） ceramics were prepared by the conventional solid-state reaction method. The partial substitution of Mn by Ni2＋ leads to a decrease in cell volume as well as a structural transition from the rhombohedral to the orthorhombic structure. Ni2＋ doping increases the electrical resistivity, decreases the semiconductor-metal transition temperature （Tms） and relatively enhances the room temperature magnetoresistance （MR）, especially in x = 0.025 and around Tins. With respect to conduction mechanism, the small polaron hopping （SPH） and the variable range hopping （VRH） models were used to ex- amine conduction in the semiconducting region.

The Luconia Province-offshore Sarawak-is a key geological unit for understanding the distribution of hydrocarbon resources in Malaysia. Nevertheless, little effort has been made to address the palaeoenvironmental characteristics of the Tertiary carbonates in the key sector of Central *** study the sedimentology and petrography of core samples from a well in Central Luconia, for which thirteen microfacies have been identified reflecting different depositional settings. This is the first microfacies scheme elaborated for Luconian carbonates. Lithofacies and microfacies distribution are compatible with deposition in a reef complex, originating around a framework reef, within the euphotic zone. Sediments were deposited in environments of backreef, reef crest, and forereef. The fair weather wave base is marked by the presence of coralline red algae, foraminifera, decreasing degree of bioclast fragmentation and other microfacies features. As a result, a depositional-environmental model is constructed, depicting a reef complex built around a framework reef developed on the margin of an isolated platform. In addition, an innovative, preliminary time series analysis of facies, microfacies and depositional environment data reveal the existence of seasonal cycles in the stacking patterns of facies and microfacies.

Treatment of Chronic Lateral Epicondylitis: Platelet Rich Plasma versus Extra-Corporeal Shock Wave Therapy

引用

Open Journal of Orthopedics 2014年第3期4卷 77-83页

作者： ahmed mohamed ahmed Othman Assistant Professor of Orthopedics El-Minia University El-Minia Egypt

Background: Several treatment options have been proposed to treat lateral epicondylitis. Both Platelet rich plasma (PRP) and Extra-corporeal Shock Wave Therapy (ESWT) are new treatment modalities for tendinopathy. Patients and Methods: Thirty seven patients suffering from chronic lateral epicondylitis (tennis elbow) for at least six months were treated in this study. The patients were divided into two treatment groups, the first group including 20 patients treated by ESWT and the second group including 17 patients treated by local injection of platelet-rich plasma. The results were evaluated using the visual analogue scale and the DASH score. Results: In the first group (treated by ESWT), the average follow-up period was 21.55 months. The average VAS improved from 8.2 to 1.95 and the average DASH score improved from 72.25 to 51.7. Moreover, 11 cases were satisfied (55%), 3 cases (15%) were satisfied with reservation and 6 cases (30%) were not satisfied. In the second group (treated by PRP), the average follow-up period was 18.47 months. The average VAS improved from 8.52 to 1.47, the DASH score improved from 72 to 48.23. Concerning patient satisfaction, 13 cases were satisfied (83.33%), 3 cases (10.52%) were satisfied with reservation and 1 case (5.55%) was not satisfied. Conclusion: Platelet rich plasma was proved to achieve superior results when compared to ESWT as regards pain relief, improvement of elbow function and patient satisfaction at follow-up.

Open versus Arthroscopic Treatment of Post-Traumatic Stiff Elbow

引用

Open Journal of Orthopedics 2014年第11期4卷 304-312页

作者： ahmed mohamed ahmed Othman Department of Orthopedic Surgery El-Minia University El-Minia Egypt

Thirty three patients with post-traumatic stiff elbow were divided into two groups. The first group included 18 patients with an average age of 31.05 years treated by open arthrolysis. The second included 15 patients with an average age of 31.66 years treated by arthroscopic method. The results were evaluated using the Mayo clinic score and DASH score for elbow function. In the open group, after an average period of follow-up 19.33 months, the average range of flexion-extension movement improved from 51.11° to 103.94°. The average Mayo clinic score improved from 63.38 to 92.83 and the average DASH score improved from 68.1 to 40.23. There were 13 cases (72.22%) excellent, 4 cases (22.22%) good and 1 case (5.55%) with the poor result. In the arthroscopic group, after an average period of follow-up 17.73 months, the average range of flexion-extension movement improved from 59.46° to 101.53°. The average Mayo clinic score improved from 62.93 to 92.73 and the average DASH score improved from 69.25 to 46.4. There were 10 cases (66.66%) excellent, 3 cases (20%) good and 2 cases (13.33%) with the poor result. Both open and arthro-scopic treatment can be effective in treatment of post-traumatic stiff elbow. Arthroscopic treatment is associated with less post-operative pain and morbidity. However, open treatment provides better range of motion and marked improvement of elbow function.
