Background: Hysterectomy, is a common operation worldwide. it is a major surgery, which leads to significant morbidity and mortality, hence, there must be a justifiable indication before the procedure is undertaken. Symptomatic uterine fibroid and utero-vaginal prolapse are common indications in this environment. Objectives: To determine the prevalence, indications and outcome of hysterectomy at Aminu Kano Teaching Hospital, Kano. Study Design: A retrospective study of all the hysterectomies that were done in Aminu Kano Teaching Hospital, Kano between 1st of Jan 2009 and 31st of Dec 2013. Result: During the period of study, there were 3843 major gynaecological operations. Out of which hysterectomy was 196, giving hysterectomy rate of 5.1% of all major gynaecological operations. Hysterectomy was highest among patient aged 40 - 49 years accounting for 54.6% of cases and the commonest indication was uterine fibroid, constituting 66.4% of all hysterectomies. Total abdominal hysterectomy was the most frequently preformed, accounting for 78.1% while, vaginal hysterectomy accounts for 20.9% of cases and subtotal hysterectomy was 1%. Hysterectomy was mostly complicated with post-operative pyrexia constituting 24% of all the complications while ureteric injury was the least, constituting 1%. There was no mortality recorded. Most of the patients who had hysterectomy were discharge in less than 10th post-operative day accounting for 91.3% of cases. However, 80.5% of patients who had vagina hysterectomy were discharge in less than 5th post-operative day. Conclusion: The prevalence of hysterectomy was 5.1%. Uterine fibroid was the commonest indication while post-operative pyrexia was the commonest complication found.

随着时间的推移,分子标记已被证明是快速和可靠的真菌种群分类。这里确定了五种菌草平菇（平菇p969,红平菇,pl-30,黄平菇,P.G）的基因组多样性,使用iTS和RAPD进行表征。使用PCR扩增rDNA的iTS区,所有菌株的iTS的大小分别在680bp至1300bp之间。iTS条带在所有菌株中都是多态性的。基于iTS区域的系统发育树表明所选择的菌株可以分为三个簇。在14个随机扩增多态性DNA（RAPD）引物中,使用的DTT 10和DTT 11具有良好的多态性和稳定的带型;但是DTT-9的多态性条带在pl-30不完全可见。为了计算不同物种之间的同源性和基因组距离,使用基于频率相似性的簇分析,物种之间的亲缘关系从50%到95%,簇A的三个物种（黄平菇,P.G和Pl-30）之间的相似性为80%至95%,簇B由两个物种（平菇P969和红平菇）组成,相似性为65%。相似性矩阵表明,亲缘关系最近的物种是黄平菇和p1-30,其具有95%的同源性。进一步的研究表明使用菌草培养平菇五菌株的有效性和确定最有效的公式,禾本科草（1）purpurum巨菌草),2)Dicranoteris dichotoma（象）,3)莱索托,4)zizantiodes 香根草,5)Mischantum Floridulus,调查了他们的的生长和产量的参数。结果表明,平菇”p969”表现出最高的生物产量和效率比所有的公式,其他菌株,菌丝体的运行速度和数量均高于平菇子实体中的“p969”和红平菇“红色”比其他三株。蘑菇菌株的质量几乎相同。我们的研究表明,菌草技术可以用来作为一种新型的、实用的、和杏鲍菇栽培容易接近的替代物,这也证明了有效利用其与RAPD标记的遗传多样性,与平菇品种分化特征。

The problem of magneto-hydrodynamic flow and heat transfer of an electrically conducting non-Newtonian power-law fluid past a non-linearly stretching surface in the presence of a transverse magnetic field is considered. The stretching velocity, the temperature and the transverse magnetic field are assumed to vary in a power-law with the distance from the origin. The flow is induced due to an infinite elastic sheet which is stretched in its own plane. The governing equations are reduced to non-linear ordinary differential equations by means of similarity transformations. These equations are then solved numerically by an implicit finite-difference scheme known as Keller-Box method. The numerical solution is found to be dependent on several governing parameters, including the magnetic field parameter, power-law index, velocity exponent parameter, temperature exponent parameter, Modified Prandtl number and heat source/sink parameter. A systematic study is carried out to illustrate the effects of these parameters on the fluid velocity and the temperature distribution in the boundary layer. The results for the local skin-friction coefficient and the local Nusselt number are tabulated and discussed. The results obtained reveal many interesting behaviors that warrant further study on the equations related to non-Newtonian fluid phenomena.

Background: Misoprostol a PGE1?analogue has increasingly been used for cervical ripening in preparation for induction of labour with variable outcome for both mother and baby. Objectives: To determine the effectiveness of Misoprostol in cervical ripening and labour outcome in Aminu Kano Teaching Hospital Kano. Study Design: A study of all patients who had cervical ripening for induction of labour using Misoprostol at AKTH Kano, Nigeria, between 1st Jan 2012-31st Dec 2013. Socio-demographic data of these patients including number of doses inserted before ripening is achieved, duration, course and outcome of labour were documented. Result: Four hundred and two women were admitted for cervical ripening. 365 women met the inclusion criteria out of the 358 folders retrieved, giving a retrieval rate of 98%. Despite this six folders did not contain enough information for the study and were excluded leaving us with a sample size of 352. They had a successful cervical ripening with an average of 2 insertions. Spontaneous onset of labour without further intervention was observed in 266 women (75.5%). However, 86 women (24.5%) were induced with oxytocin following cervical ripening. The mean duration of labour among those that had spontaneous onset of labour following Misoprostol insertion was 9.8 hours. 96% of the patients had vaginal delivery while 4% had Caesarean section. Conclusion: Misoprostol was associated with favorable outcome following cervical ripening with a low caesarean section rate.

information on Culex mosquitoes (vectors of filarial worm and viral encephalitis) from northern Nigeria is scanty, hindering evidence-based control. Here, two Culex populations (Kano and Kaduna) were characterized. Culex quinquefasciatus and Culex pipiens were found breeding in sympatry, with some hybrid individuals identified. larval bioassays revealed high temephos resistance (lC50s = 1.34 mg/ml and 3.01 mg/ml for Kano and Kaduna, respectively). larvae were more sensitive to α-cypermethrin (lC50s = 0.026 mg/ml and 0.067 mg/ml for Kano and Kaduna). WHO adult tube bioassays revealed high pyrethroid and DDT resistance, with mortalities of 44.01% ± 6.79%, 35.83% ± 12.58%, 29.69% ± 9.97% and 52.47% ± 4.34% for permethrin, deltamethrin, α-cypermethrin and DDT, respectively. Highest resistance was observed with bendiocarb (mortality = 13.58% ± 3.98%). High resistance was obtained with fenitrothion and malathion (mortalities = 21% ± 4.76% and 56.47% ± 8.67%, respectively), while a full susceptibility was observed with pirimiphos-methyl. Pre-exposure to piperonylbutoxide (PBO) significantly recovered α-cypermethrin susceptibility (mortality = 82% ± 5.16%, χ2 = 50.99, p ith the conventional bioassay (mortality = 32 ± 7.30). Mortalities of ined in cone bioassays with Yorkool, DuraNet and PermaNet3.0 (side panels) nets, suggesting a loss of efficacy of conventional long-lasting insecticidal nets. However, mortalities of 99% and 86% were obtained in Kano and Kaduna populations using the roof of PermaNet3.0 (containing PBO and deltamethrin). Despite the high frequency of the 1014F VGSC knockdown resistance mutation allele (0.90), no correlation was observed between the 1014F kdr genotype and resistance phenotype. Sequencing of fragments of the acetylcholinesterase-1 gene detected no G119S mutation, in malathion-alive and malathion-dead females. These suggest a preeminent role of metabolic resistance in these Cu
