采用沙培法,以玉米品种V1和V2为试验材料,定量分析缺钾对玉米生长和发育的影响。从胚芽鞘叶完全展开时,设置营养液中钾的浓度为3个梯度,分别为KH=8mmol·L-1;KM=4mmol·L-1;KO=0mmol·L-1。从胚芽鞘叶完全展开到吐丝期经常浇这3种营养液。用有效积温来计算玉米生长期间所需热量,把每日完好的叶面积作为玉米生长的衡量指标;每天记录每株玉米的叶片数,不管叶片的大小,作为衡量植株生长发育的方法。在每一个钾元素供应水平上,品种V1和V2的叶片数和自播种以来的受热时间呈直线相关。在KO水平上,V1和V2的发育速率分别是10%和15%,相对于KH水平来说是低的。在11片叶子期间,KO水平上的叶面积大约比KH水平上的低46%,KM水平上的叶面积大约比KH水平上的低25%;在玉米抽雄期,KO水平上的叶面积相对于KH来说减少37%,比KM水平上的少26%。这种差异从抽穗期开始一直保持到吐丝期。

For the development of 19-plex Y STR system and polymorphism studies in local ethnic populations sixteen markers of non-recombining regions (NRY) of Y chromosome, which show high power of discrimination among individuals, were selected in this study. Blood samples (600) were collected from the males of three most common castes of Pakistani population (Arain, Awan and Rajput) with different parent lineages. Three markers (DYS385a/b, DYS389I/II and YCAIIa/b) among 16 Y STRs are double-targeted regions of the Y chromosome and thus provide two polymorphic peaks for each respective primer set. These 16 Y-STRs were developed into Megaplex system for simultaneous amplification of all markers within the population. The overall power of discrimination observed in focused populations was 60.5%, 66.5% and 55% in Rajput, Awan and Arain casts respectively. This discrimination power will be helpful in human identification for forensic casework studies including sexual assaults and paternity testing.

Wheat [Triticum aestivum L. (Poaceae)] is the staple diet of people in Pakistan. It is attacked by many types of pests. Therefore the purpose of this study was to assess the impact of climate change on the ecology and epidemiology of various wheat pests in Punjab, Pakistan. Results indicate that maximum weeds hot spots 242 (5.98%) Phalaris minor, 45 (1.18%) wild oat and 203 (5.01%) broad leaf weeds were noted in 2015. Aphid 31 (0.86%) hot spots were recorded in 2016 while maximum army worm 13 (0.26%) hot spots were noted in 2017. Maximum 70 (1.73%) spots of yellow rust and 85 (2.10%) hot spots of brown rust were observed during 2015 while 84 (4.16%) spots of loose smut were observed during 2017. ANOVA shows that years have no significant difference (P > 0.05) but weeks have significant effect on occurrence of these pest incidences except brown rust. But regression ANOVA was significant (P ≤ 0.05) and regression models equations have been developed on the bases of recorded data. Pest incidence was taken as dependent variable Y and weather factors i.e. minimum temperature as X1, maximum temperature as X2, relative humidity as X3 and rain fall as X4 were taken as independent variables. This study will help in recommendations for moving forward aiming at integration of biology of rust and smut diseases of wheat with changing climate for development of resistant varieties for resilient and durable management of these pathogens.

Purpose: We studied the drug resistance of different microbes from clinical isolates. The morphological characteristics of bacteria were observed through culture characteristics and by carrying out gram staining techniques while the biochemical characteristics of bacteria were carried out by biochemical test. Methods: A total of 324 samples were collected from suspected patients visiting different hospitals at district Peshawar. For morphological identification, samples of clinical isolates were analyzed by blood agar, MacConkey agar and Eosine Methylene Blue, identified by gram staining and characterized by different biochemical tests. Antibiotic Sensitivity test by Modified Kirby-Bauer Disc diffusion method was used to test the in-vitro susceptibility of the identified isolates to different antibiotics such as Ceftazidime, Ceftazidime, Ceftriaxone, Cefepime and Imipenem. Results: These resistant non-lactose fermenting gram negative bacteria were isolated from samples of pus/wound (33.30%, n = 108/324), blood (33.30%, n = 108/324), urine (23.30%, n = 75/324) and from ascetic/pleural fluids (10.20%, n = 33/324). The study revealed that the percentage of non-fermenting bacterial infection was higher in females (53%) as compared to males (47%) along with higher infection observed in the age group of 11 - 30 years. Pseudomonas aeroginosa showed high resistance against Cefepime (88.80%), followed by Cefoperazone (55.50%), Ceftazidime (48.10%), Ceftriaxone (33.30%). Imipenem was active with low resistance (7.40%). More resistance was seen in Morganella morganii against Imipenem (66.70%) followed by Cefoperazone (55.50%), Ceftriaxone (55.50%). Cefepime showed low resistance (11%). Multi-drug resistant Proteus mirabillis was highly resistance to Ceftriaxone (74.07%), followed by Cefepime (59.20%), Cefoperazone (44.40%) and low resistance for Imipenem (25.90%). Salmonella typhi demonstrated high resistance against Imipenem (74.07%), followed by Ceftriaxone (40.70%), Ceftazi

目的探讨振幅整合脑电图(aEEG)在心肺复苏(CPR)患儿早期预后评估中的价值。方法选择2017年3月—2019年5月本院儿童重症监护室(PICU)收治的CPR患儿32例进行aEEG及同步视频脑电图(vEEG)监测,包括患儿复苏时长、住院时间及儿童改良格拉斯哥昏迷评分(GCS)。根据发病后3个月脑功能评分量表(PCPC)分为预后良好组(1~3分)和预后不良组(4~6分)。用Spearman秩相关分析aEEG与vEEG及改良GCS评分的相关性;用受试者工作特征曲线(ROC)评价aEEG、vEEG及改良GCS对脑功能早期预后的价值。结果两组不同预后患儿之间年龄、性别、住院时间差异均无统计学意义(P>0.05),复苏时长、aEEG分级、vEEG分级与改良GCS评分差异有统计学意义(P<0.05);Spearman秩相关分析显示aEEG与vEEG及改良GCS均呈正相关(r值分别为0.630及0.576,均P<0.001);ROC曲线分析显示aEEG预测CPR患儿脑功能预后的ROC曲线下面积(AUC)=0.901,最佳截断值为1.5时,灵敏度为0.958,特异度为0.625,vEEG的AUC=0.880,最佳截断值为3.5时,灵敏度为0.833,特异度为0.875;改良GCS的AUC=0.779,最佳截断值为2.5时,灵敏度为0.833,特异度为0.625。结论 aEEG不仅能用于CPR患儿早期预后评估,而且比vEEG和改良GCS预测价值更高。

Objective: To test the coalescence effect of two chemotherapy drugs at low effective dose(cisplatin and taxotere) combined with pomegranate juice on A549 cancer cells. Methods: Infrared spectroscopy method is a qualitative test that was performed to ensure the existence of the phytochemicals providing the antioxidant activity through the presence of the hydroxyl group(-OH). The viability of A549 cell line and normal MCs was tested using the neutral red uptake, Clonogenic survival, XTT and Cell migration assays. Results: Our results showed that this combination firstly led to a greater decrease in the viability of cells comparing to those treated with chemotherapy drugs alone, and secondly led to a significant reduction in cell migration. Conclusions: These data suggest a synergistic effect between the pomegranate and cisplatin which makes probably this combination a powerful option for treating lung adenocarcinoma and in parallel minimizing the systemic side effects.
