Vestibular schwannoma: anatomical, medical and surgical perspective
Ashfaq Ul Hassan,Ghulam Hassan,Zahida Rasool
International Journal of Research in Medical Sciences , 2013, DOI: 10.5455/2320-6012.ijrms20130811
Abstract: The term "acoustic" is a misnomer, as the tumor rarely arises from the acoustic (or cochlear) division of the vestibulocochlear nerve. The correct medical term is vestibular schwannoma, because it involves the vestibular portion of the 8th cranial nerve. They are benign, rather rare tumors. They expand in size and grow larger; they can push against the brain. While the tumor does not actually invade the brain, the pressure of the tumor can displace brain tissue.

The article tries to summarize the microbiological aspects along with the anatomical and surgical perspectives for in depth knowledge and reasons for spread of disease. The photographs indicate the radiological spectrum of the disease in line with the text. [Int J Res Med Sci 2013; 1(3.000): 188-190]
Surgical significance of variations in anatomy in the biliary region
Ashfaq Ul Hassan,Showqat A. Zargar,Aijaz Malik,Pervez Shah
International Journal of Research in Medical Sciences , 2013, DOI: 10.5455/2320-6012.ijrms20130812
Abstract: Variations in the anatomy of the gallbladder, the bile ducts, and the arteries that supply them and the liver are important to the surgeon, because failure to recognize them can cause iatrogenic injury to the biliary tract. A surgeon should be always be careful while operating in this area. In addition these anomalies are associated with a range of other congenital anomalies, including biliary atresia and cardiovascular or other gastrointestinal malformations, biliary lithiasis, choledochal cyst, anomalous pancreaticobiliary junction etc, so a look out for other anomalies should be carried out simultaneously.

Acetylcholinesterase Based Detection of Residual Pesticides on Cotton  [PDF]
Syed Zameer Ul Hassan, Jiri Militky
American Journal of Analytical Chemistry (AJAC) , 2012, DOI: 10.4236/ajac.2012.32013
Abstract: This study describes the measurement of bio-electrical signals caused by enzymatic inhibition of acetylcholinesterase (AChE) for the detection of organophosphorous and carbamate pesticides which are the strong inhibitors of AChE and prevents its normal function of the rapid removal of acetylcholine (Ach). Biosensor Toxicity Analyzer (BTA) was used for the testing and enzyme activity was determined by acetylthiocholine chloride (ATCCl) as enzyme substrate. The monitoring of changes in bio-electrical signals caused by the interaction of biological substances and residues were evaluated. Two samples of cotton were analyzed. Cryogenic homogenization was carried out for sample pretreatment and Soxhlet extraction method (SOX) was used for extraction. The resulted extracts were concentrated and then injected in the BTA. The method shows reasonable results and can successfully be utilized for the detection of residual pesticides on different types of cotton.
Determining Irrigators Preferences for Water Allocation Criteria Using Conjoint Analysis  [PDF]
Noor Ul Hassan Zardari, Ian Cordery
Journal of Water Resource and Protection (JWARP) , 2012, DOI: 10.4236/jwarp.2012.45027
Abstract: Water allocation based on multiple criteria has the potential to maximize the total benefits to be gained from the use of a single unit of water. However most of the multi-criteria methods inherently include a considerable degree of subjectivity. In this study, we have attempted to reduce the subjectivity factor from water allocation decision-making process by introducing a conjoint analysis method. Opinions on the importance of a number of water allocation criteria were sought from a large number of irrigation farmers. The opinion survey data were then analyzed using the traditional conjoint analysis method which is widely used to analyze marketing surveys. The analysis allowed objective determination of the relative importance of five water allocation criteria (i.e. net farm income, percent of family working on the farm, amount paid to irrigation agency for canal water share). Each water allocation criteria was divided into three levels and utility values for each criteria level were estimated from the farmers’ preferences on five water allocation criteria (attributes). The conjoint survey results revealed that the respondents prefer that “annual net farm income” be the most important attribute in water allocation decisions. As would be expected the vast majority of the respondents overwhelmingly placed the “water price” in the last position.

Abstract: Objective: To highlight etiological factors leading to radial nerve injury resulting in wrist drop, withparticular reference to iatrogenic causes. Design: Retrospection & Descriptive. Material & Methods: One hundredpatients of all ages and both sexes with wrist drop. Data of clinical assessment after detailed history and examinationas well as electro diagnostic studies was recorded on pre-designed assessment proforma. The outcome was charteddown for frequency of etiology of the wrist drop. Setting: Rehabilitation Medicine Department of Combined MilitaryHospital (CMH) Multan and Armed Forces Institute of Rehabilitation Medicine (AFIRM). Results: The major cause ofinjury was splinter/gun shot injury 31%, mis-placed injection at mid-arm 21%fracture of humerus was 21%, compressionneuropathy 16%, and stab wound 11% caused wrist drop. Electro-physiological studies revealed that 85% patients hadinjury to radial nerve at mid-arm, 9% had injury to posterior interosseous nerve while 4% had injury to superficial branchof radial nerve and only 2% had normal study. Electrodiagnostic studies also revealed that majority of the patientssuffered from axonotmesis (44%) and neurapraxia (38%), whereas (16%) were neurotmesis. Conclusion: The mostcommon cause of radial nerve injury is trauma. It is also found that the frequency of radial nerve palsy due to iatrogeniccauses is quite high. In addition to the clinical examination, the nerve conduction studies and electromyography provedto be the better investigation technique in the assessment of the location, severity and extent of the peripheral nerveinjury and subsequently guides in starting the proper treatment option due to early referral of patient to the concernedfields.

Relationship of Uric Acid with Superoxide Dismutase (Sod) in Induced Hyperuricemic Rat Model  [PDF]
Shiza Batool, Iftikhar Ahmed, Muhammad Sarwar, Hafeez ul Hassan
Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.34054
Abstract: Increase uric acid levels have been found in oxidative stress. Urate radicals do not react with oxygen to form another peroxy radical, thus increasing the efficacy of uric acid as an antioxidant. Therefore, this study is designed to measure the level of uric acids and find out the relationship of uric acid with superoxide dismutase in induced hyperuricemic model. Forty male albino rats with an average weight of 180 ± 2 g were selected. The rats were grouped. The animals were fed on standard diet and given tap water ad libitum until treatment. Albino rats were divided into four groups. Group A(10)-control given only standard diet, group B(10) fed on 60% fructose with standard diet , group C(10) fed on fructose, standard diet and intraperitonially oxonic acid 250 mg/kg and group D (10) only on injection intraperotonially oxonic acid 250 mg/kg. At the end of study 10 mL of blood was drawn from heart of rats. Then blood was estimated for superoxide dismutase and uric acids done by kit methods randox-manual/Rx monza UA230/UA 233. Results: In Group C superoxide dismutase was found to be 32 % (244 mg/dL ± 2.23) more than control. In the same group the uric acid concentration was highly significantly correlated with control. Conclusion: The uric acid concentration increases when we take fructose up to 60% in our diet. It also increases superoxide dismutase concentration. More than this value may have inverse effect on the uric acid level and its role as an antioxidant may become inversed.
Tax Shield and Its Impact on Corporate Dividend Policy: Evidence from Pakistani Stock Market  [PDF]
Akhlaq ul Hassan, Mubashar Tanveer, Muhammad Siddique, Muhammad Mudasar
iBusiness (IB) , 2013, DOI: 10.4236/ib.2013.54023

The problem: what is the taxation impact on dividend policy? While much optimal taxation research focuses on the economic effects of taxation, the purpose of this study is to add a new dimension by investigating the relationship between taxation and payout ratio and some other variables of dividend policy. These relations are tested using the data from financial statements of KSE listed companies. The results show that tax shield has no significant relation to the dividend payout ratio but mostly dividend policy is due to the size of the firm and its profitability.

Quantification of River Bank Erosion and Bar Deposition in Chowhali Upazila, Sirajganj District of Bangladesh: A Remote Sensing Study  [PDF]
Md. Shareful Hassan, Syed Mahmud-ul-islam
Journal of Geoscience and Environment Protection (GEP) , 2016, DOI: 10.4236/gep.2016.41006
Abstract: River bank erosion is one of the frequent but the most unpredictable disasters that occur every year in Bangladesh. In this paper, Landsat TM-5 and Landsat-8 imageries from 1989 and 2015 were used to detect changes of present land use, river erosion and bar deposition in Chowhali Upazila, Sirajganj district of Bangladesh. This study reveals that human settlement, forest, seasonal crops and agriculture features decrease, while river coverage increases dramatically. About 1340 hectare areas have been eroded, while 630 hectares are deposited as channel bar in the study area over the last 26 years. Finally, an accuracy assessment is conducted between the test data and each land use feature. The overall classification accuracy was 97% and 98% in 1989 and 2015 respectively. Moreover, 98% accuracy is found in erosion while 97% is found in bar deposition areas.
