Almost all healthy female chickens are expected to optimally produce eggs regularly. To maximize profits, nonproductive birds are often culled in commercial layer farms without due considerations to causes. Genetic and therapeutic manipulations to increase egg production per cycle often predispose birds to obstetric problems. Information on the detection and management techniques of reproductive abnormalities of the domestic chicken appear scarce. This study reports on clinical evaluation and surgical management of three major reproductive abnormalities of the commercial layer chickens. Egg yolk peritonitis, oviduct impaction and egg bound conditions were diagnosed and surgically managed following standard surgical procedures. Palpation and abdominocenthesis using flexible rubber catheter, abdomino-pelvic ultrasound scan and ventra-dorsal X-ray techniques were used to establish diagnosis. In all reported conditions herein, surgery was employed to correct them. The study showed values of diagnostic imaging and surgery to correcting obstetric conditions of domestic chickens.

Participatory Evaluation of the Relative Livestock Populations and the Assessment of the Status and Impacts of Newcastle Disease in Rural Communities of Two Northeastern States, Nigeria

Livestock is an important component of food security in many developing nations. However, animal diseases continue to undermine animal production and public health efforts thus widening poverty gap. Unfortunately, the conventional and what seems to be inefficient “top to bottom” disease surveillance and control policies are heavily relied upon such that negative impacts of diseases are underestimated. Participatory disease surveillance (PDS) techniques using semi-structured questioning assisted by key informants targeting focus groups were employed in 60 randomly selected villages of two Nigerian States during the years 2012 to 2014. Haemagglutination and ELIsa tests to detect antibodies to Newcastle disease (ND) were conducted on 950 poultry sera. The status and economic burden of Newcastle disease and the relative livestock populations and some ethno-veterinary practices of these livestock farming communities were brought to the fore. Poultry, goats, cattle, sheep and pigs in descending order were the major livestock species kept in the study areas to which Kendalls Coefficient of Concordance (W = 0.9) agreed strongly. Accordingly, ND, lousiness, fowl pox and coccidiosis with percentage scores of ND-52%, Fowl Pox-31%, lousiness-17% and salmonellosis-10% were important causes of poultry morbidity and mortality. ND sero-prevalence was 39%, relative morbidity;mortality and case fatality rates of 95%, 78% and 82% respectively were appraised. Again ND, coccidiosis, ectoparasitism and fowl pox were reported as seasonal poultry diseases (W = 0.6). Solanum nodiflorum and Momordica balsalmina were used to treat ND. Major livestock kept, and the ND status and effects in poultry in these livestock farming communities are here reported. Institutionalization of PDS would better inform strategic livestock policy reforms, and improve national food security and diseases surveillance and reporting system in Nigeria.

燃料电池和金属-空气电池是最有前途的清洁能源系统,其电化学过程很大程度上依赖于催化氧还原反应(ORR)。然而,阴极上的反应往往受到ORR反应动力学的限制,缓慢的反应动力学导致电池(燃料电池和金属-空气电池)性能低下。采用高效阴极电催化剂是降低ORR过电位、实现快速反应动力学和提高器件性能的有效途径之一。Pt基催化剂是目前最好的阴极催化剂,具有最好的ORR电催化性能,但其昂贵的成本是其商业化的主要障碍。因此,开发低成本、高效的非贵金属催化剂具有重要的实际应用价值。近年来,含铁氮掺杂MOFs衍生的碳和碳负载的MOFs材料因其良好的ORR性能而受到广泛的关注,显示出替代商业Pt/C催化剂的潜力。开发经济高效的非贵金属催化剂用于酸性和碱性介质的ORR是清洁能源生产的迫切需要。单原子催化剂显著改善了ORR的性能,然而,催化剂结构溶解导致的活性衰减仍然是一个挑战。因此,我们提出了一种简单的保护saC结构的策略,即用Fe-N修饰Fe-ZI-LF衍生碳纳米管,命名为Fe sa@CNTs。Fe sa@CNTs催化剂在碱性介质中表现出良好的ORR性能,起始电位E=0.998 V,半波电位E=0.898 V,分别比商业20%Pt/C催化剂高28 m V和29 m V。此外,Fe sa@CNTs在酸性介质中表现出较高的半波电位(E=0.8290 V),与Pt/C(E=0.8292 V)相当,这优于最近报道的ORR催化剂性能。密度泛函理论(DFT)表明,Fe-N中的Fe和O的能量轨道差较小,改善了速率决定步骤中电子转移到反应中间体(OH*)上的速度,使Fe sa@CNTs在酸性和碱性介质中都具有更高的催化活性。在不添加表面活性剂的条件下,将双金属ZIFs晶体在还原石墨烯薄片(r GO)上水热生长,制备了Co Ni-ZIF/r GO。在相同的测试条件下,所制备的复合材料的ORR催化性能优于原始的Co Ni-ZIF。通过物理和化学表征来测量材料的性能。结果表明,在碱性介质中,Co Ni-ZIF/r GO有利于催化氧还原反应。值得注意的是,Co Ni-ZIF/r GO的半波电位为0.865 V,超过了商业20%Pt/C(0.860 V RHE),反应过程显示近4个电子转移途径。ZIFs与r GO纳米片之间的协同作用促进了反应中间体的电子快速转移和吸附,从而提高了电催化活性。

Introduction: Studies on RA (rheumatoid arthritis) and cardiovascular risk in African countries are scarce. Objective: To investigate the relationship between RA and cardiovascular risk in Cameroonian patients. Methodology: In 50 Black RA patients and 51 matched healthy individuals from the general population, we studied cardiovascular risk factors validated by the WHO. Cardiovascular risks estimates were carried out using WHO risk charts for the African region. Epi-info, R and SPPS were used for the statistical analysis. Results: Overall and abdominal adiposity as expressed by increased body mass index and abdominal obesity, were all markedly increased in RA patients compared to non-RA subjects [70% vs. 47%, OR (95% CI) = 2.62 (1.16 - 5.94), p = 0.026;and 54% vs. 33%, OR (95% CI) = 2.34 (1.05 - 5.25), p = 0.045 respectively]. RA patients were more physically inactive than their non-RA counterparts (20% vs. 0, p = 0.001). Whereas RA was associated with a reduced odds of alcoholism [OR (95% CI) = 0.19 (0.06 - 0.62), p = 0.005]. Increased BMI seemed to occur independently of methotrexate (p = 0.76), hydroxychloroquine (p = 0.59), corticosteroids (p = 0.79) treatments, and independently of sex (p = 0.15), age (p = 0.67), and sedentary lifestyle (p = 0.16) in RA patients;but their BMI was weakly correlated with disease duration (r = 0.26;p = 0.074). Meanwhile, male gender was associated with a reduced odds of abdominal obesity [OR (95% CI) = 0.02 (0 - 0.4), p = 0.011]. Cardiovascular risk, comparable by proportions between RA and non-RA subjects, was low in 26 patients (78.8%) and 30 non-RA subjects (83.3%) respectively. Conclusion: Despite the high adiposity burden and a sedentary lifestyle experienced by RA patients compared to their healthy counterparts, RA was not associated with cardiovascular risk as estimated by WHO risk charts.
