Bacteriocins are gene-encoded inhibitory proteins and those produced by Gram-positive Lactic acid bacteria. Some bacteriocins even display antagonistic activity towards Gram-positive food borne pathogens and spoilage organisms. This present study involves isolation of Bacteriocin-producing lactic acid bacteria from a variety of milk and milk products. The physico-chemical properties of the isolated bacteriocin producing bacterial strains were screened. The isolated bacteriocin bacterial strains were biochemically characterized and identified. Further, the isolated effective bacterial strain was used as a fish feed and its effect on their growth was evaluated. The evaluated data continue to demonstrate that the bacteriocin producing bacterial strains will have greater potential in the food products industry.

Peripheral nerve blocks have become important in clinical practice because of their role in post-operative pain relief, shortening of patient recovery time & avoiding risks and adverse effects of general anaesthesia. Bupivacaine is a long acting local anaesthetic. Due to its long duration of action and combined with its high quality sensory blockade compared to motor blockade it has been the most commonly used local anaesthetic for peripheral nerve blocks. Ropivacaine is a newer, long acting local anaesthetic whose neuronal blocking potential used in peripheral nerve blockade seems to be equal or superior to bupivacaine. Studies show that it has significantly greater safety margin over bupivacaine. Hence here is an attempt through the study to compare bupivacaine with ropivacaine in supraclavicular brachial plexus block in ASA II&III patients.
周围神经阻滞因其在缓解术后疼痛、缩短患者恢复时间、避免全身麻醉的风险和不良反应等方面的作用而在临床实践中变得越来越重要。布比卡因是长效局部麻醉剂。由于其作用持续时间长,并且与运动阻滞相比,它具有高质量的感觉阻滞,是周围神经阻滞中最常用的局部麻醉。罗哌卡因是一种较新的长效局部麻醉剂,其用于周围神经阻滞的神经元阻断电位似乎等于或优于布比卡因。研究表明,它比布比卡因有更大的安全边际。因此,本文试图通过研究比较布比卡因与罗比卡因在ASA ii和iii型患者锁骨上臂丛阻滞中的作用。

Velocity slip boundary condition in parallel-plate micro-channels filled with hyper-porous media is studied using differential transformation method (DTM) in order to find an analytical approximate solution. The results focus on slip flow regime (i.e., for Knudsen numbers in the range 10 −3 < Kn < 10 −1 ). The Darcy-Brinkman-Forchheimer model is applied to study the effect of nonlinear drag term further boundary-friction effects on hydrodynamic of gas flow in micro-channels. The results show that DTM results are in good agreement with numerical ones. Also, it is observed that decreasing the value of Darcy number flattens the velocity profile while this trend is opposite for decreasing the Forchheimer number. Also, increasing the value of  causes to increase the velocity slip at the wall.
利用微分变换方法研究了超多孔介质填充平行板微通道的速度滑移边界条件,并求出近似解析解。结果集中于滑移流态(即,克努森数在10−3 < Kn < 10−1范围内)。应用Darcy-Brinkman-Forchheimer模型研究了非线性阻力项进一步边界摩擦效应对微通道内气体流动动力特性的影响。结果表明,DTM计算结果与数值计算结果吻合较好。Darcy数的减小使速度剖面变平坦,而Forchheimer数的减小则使速度剖面变平坦。同时,增大的值也会增加壁面处的速度滑移。

Introduction: Femur fractures are very painful. The peripheral nerve block provides good analgesia in these patients before performing regional anesthesia. This study aims to compare 2 local anesthestics in femoral nerve block for analgesia in preoperative positioning and postoperative analgesia of patientsMethods: Prospective, randomized study was conducted on 60 patients (18-60 years) of ASA I&II scheduled for femur surgery under combined spinal epidural. anaesthesia In group B (n=30), femoral nerve block(FNB) was performed with 0.2% bupivacaine (30ml) and in group R(n=30), 0.2% ropivacaine (30 ml) was used. Various parameters like numeric rating pain scale, time to spinal anaesthesia, sensory and motor block onset times and durations, time to first analgesic use, intraoperative & postoperative visual analog scale (VAS) data, post- operative epidural top ups, vitals and side effects were recorded for each patient.Results: Pain assessed on visual analogue scale (VAS) during positioning was significantly less in FNB group using 0.2%bupivacaine at 5 minutes. Time to perform spinal block was significantly shorter in FNB group using 0.2% bupivacaine (8.30 min) versus ropivacaine group (17.30 min). But postoperative analgesic requirements were more in ropivacaine group and duration of analgesia was prolonged in bupivacaine group.Conclusion: With bupivacaine time to perform spinal anesthesia was reduced and postoperative analgesia was better with bupivacaine group.
股骨骨折是非常痛苦的。周围神经阻滞为这些患者在进行区域麻醉前提供了良好的镇痛效果。本研究旨在比较两种局麻在股神经阻滞中对患者术前定位和术后镇痛效果的影响。方法:前瞻性、随机研究60例(18-60岁)在联合脊髓硬膜外下行ASA i和ii级股骨手术的患者。麻醉B组(n=30)采用0.2%布比卡因(30ml)行股神经阻滞(FNB), R组(n=30)采用0.2%罗哌卡因(30ml)。记录每位患者的各种参数,如数值评定疼痛量表、脊髓麻醉时间、感觉和运动阻滞发作时间和持续时间、首次使用镇痛药时间、术中和术后视觉模拟评分(VAS)数据、术后硬膜外充值、生命体征和副作用。结果:使用0.2%布比卡因的FNB组体位5分钟时视觉模拟评分(VAS)疼痛明显减轻。0.2%布比卡因FNB组脊髓阻滞时间(8.30 min)明显短于罗哌卡因组(17.30 min)。但罗哌卡因组术后镇痛需求较多,布比卡因组术后镇痛时间延长。结论:布比卡因组腰麻时间缩短,术后镇痛效果较好。

Acraea terpiscore L. is commonly known as the Tawny Coster butterfly, it belongs to the Nymphalidae or Brush-footed butterfly family. Its common larval hosts depend on the availability of Turnera subulata. The study has been carried from January to July 2015 in Thammampatti, Salem district in Tamilnadu. A. terpiscore larvae were found in Turnera subulata and Passiflora foetida. From this observation it is evident that host preference is prevalently exhibited in larval feeding of Tawny Coster. On the availability of T. subulata the choice of P. foetida is found meagre. The caterpillars were counted once a week in both the populations during an observation period of six months. T. subulata and P. foetida plants respectively envisaging its host preference of T. subulata over P. foetida. It is reported here for the first time as a new larval host of Tawny Coster.
Acraea terpiscore L.通常被称为茶色蝴蝶,它属于蛱蝶科或刷足蝴蝶科。其常见的幼虫寄主依赖于黄轮虫的可用性。该研究于2015年1月至7月在泰米尔纳德邦塞勒姆地区的Thammampatti进行。在黄兜草和西番莲中均发现了小蠹蛾幼虫。由此可见,黄颡鱼幼虫在取食过程中普遍表现出寄主偏好。在大叶茅的可用性上,发现小叶茅的选择很少。在为期6个月的观察期内,每周对两个种群的幼虫进行一次计数。设想其寄主对扁叶蝉比扁叶蝉的偏好。本文首次报道其为茶树蛾的新幼虫寄主。

Objectives: The objectives of the study are to study etiology, manifestations and outcome of acute kidney disease. Method: In present study, patients with acute kidney disease admitted to Sir T Hospital, Govt. Medical College Bhavnagar between June 2013 and July 2014 are studied with a detailed history, general physical examination, and systemic examination and investigated as per the proforma. Data collected, analysed and the test of significance was calculated by chi square, student’s t test. Results and conclusion: A prospective study of 100 cases of acute kidney injury admitted to Sir T Hospital Bhavnagar between June 2013 and July 2014 is done. Diagnosis of the patients is based on the clinical and laboratory evidence of elevated blood urea and serum creatinine. This study showed male to female ratio of 2.7:1. Maximum incidence is seen between 40-65 years. The study showed various etiological factors associated with acute kidney injury like malaria, snake bite, septicaemia, heart failure, cirrhosis, drug nephrotoxicity and acute gastroenteritis. 8 patients had obstructive uropathy. Common symptoms are oliguria and vomiting, other clinical features are fever, jaundice, loose stool and peripheral edema. However, septicaemia is the predominant cause of acute kidney injury in our study.  Out of 100 cases, 93% patients survived and 7% expired. 83% patients are on conservative management and 17% underwent hemodialysis. Out of 100 cases, 51 patients are having associated illness which made them prone to develop AKI. Mortality is also seen more among this group. Most common comorbid illnesses are DM, HTN and IHD.
目的:研究急性肾脏疾病的病因、表现和转归。方法:对2013年6月至2014年7月在巴夫纳格尔政府医学院Sir T医院住院的急性肾病患者进行详细的病史、全身检查和系统检查,并按形式进行调查。数据收集、分析和显著性检验采用卡方检验、学生t检验计算。结果与结论:对2013年6月至2014年7月在巴夫纳格尔Sir T医院收治的100例急性肾损伤患者进行了前瞻性研究。患者的诊断是基于临床和实验室证据升高的血尿素和血清肌酐。该研究显示男女比例为2.7:1。发病率最高见于40-65岁之间。该研究显示了与急性肾损伤相关的各种病因,如疟疾、蛇咬伤、败血症、心力衰竭、肝硬化、药物肾毒性和急性胃肠炎。梗阻性尿路病变8例。常见症状为少尿和呕吐,其他临床表现为发热、黄疸、便稀和周围水肿。然而,在我们的研究中,败血症是急性肾损伤的主要原因。在100例病例中,93%的患者存活,7%的患者死亡。83%的患者接受保守治疗,17%的患者接受血液透析。在100例病例中,51例患者患有相关疾病,这使他们容易发展为AKI。这一群体的死亡率也更高。最常见的合并症是糖尿病、HTN和IHD。

A class of fractional-order differential models of RNA silencing with memory is presented in this paper. We also carry out a detailed analysis on the stability of equilibrium and we show that the model established in this paper possesses non-negative solutions. Numerical solutions are obtained using a predictor-corrector method to handle the fractional derivatives. The fractional derivatives are described in the Caputo sense. Numerical simulations are presented to illustrate the results. Also, the numerical simulations show that, modeling the phenomena of RNA silencing by fractional ordinary differential equations (FODE) has more advantages than classical integer-order modeling.

Pineapple peels are considered as waste in industrial and house hold setting. This research was aimed at converting these waste into useful product through bioconversion using Aspergillus niger . The proximate analysis, reducing sugar, pH, and titratable acidity of the both ripe and unripe peels of pine apple was carried out at the onset of the fermentation and at an interval of 24 hours for 96 hours. These analyses carried out on both ripe and the unripe peels of pineapple showed that, the crude protein increased from 3.96% to 9.84% in the ripe pineapple peel and increased from 3.21% to 6.41% in unripe peels. The crude fiber reduced from 14.09% to 3.23% in the ripe pineapple peels while the crude fiber of the unripe peels reduced from 10.15 to 4.62 at the end of the 96 hour fermentation. Increase in titratable acidity, reduction in reducing sugar and pH was recorded for both ripe and unripe peels during the fermentation period. The optimum bioconversion was recorded at 72 hours of fermentation where the pick in the crude protein was recorded. The fat content of the pineapple peel in both ripe and unripe pineapple peel remain fairly constant throughout the fermentation period. The ripe pineapple peel yielded more protein compared to the unripe pineapple peels. This is an indication that the ripe pineapple peels are more preferred for industrial application.
菠萝皮在工业和家庭环境中被认为是废物。本研究旨在通过黑曲霉的生物转化将这些废物转化为有用的产品。在发酵开始时对成熟和未成熟的松果皮进行近似分析、还原糖、pH和可滴定酸度,每隔24小时进行96小时的测定。对成熟和未成熟菠萝果皮的分析表明,成熟菠萝果皮的粗蛋白质含量从3.96%增加到9.84%,未成熟菠萝果皮的粗蛋白质含量从3.21%增加到6.41%。发酵96 h后,成熟菠萝皮粗纤维含量由14.09%降至3.23%,未成熟菠萝皮粗纤维含量由10.15%降至4.62%。在发酵过程中,成熟果皮和未成熟果皮的可滴定酸度增加,还原糖减少,pH值降低。在发酵72小时时记录了最佳生物转化率,并记录了粗蛋白中的pick。熟菠萝皮和未熟菠萝皮的脂肪含量在整个发酵过程中保持相当稳定。成熟的菠萝皮比未成熟的菠萝皮产生更多的蛋白质。这表明成熟的菠萝皮更适合工业应用。
