Long-Term Administration of HMG-COA-Reductase Inhibitor (Simvastatin) affects Brain Serotonin Neurotransmission in Male Rats |
| Simvastatin, an important member of statin family is widely prescribed as cholesterol-lowering agent. Like other statins it acts by inhibiting the rate limiting enzyme 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase, responsible for the endogenous production of cholesterol which forms an essential part of neuronal cell membranes. Lowering of cholesterol has been reported to alter the brain chemistry and hence neurotransmission. To understand the association between low cholesterol and brain serotonin (5-HT) we monitored the effect of ....Click

| The South Asiatic Monsoon and Flood Hazards in the Indus River Basin, Pakistan |
| Flood is the most common of all environmental hazards. Each year floods claim over 20,000 lives adversely affect around 75 million people . The reason lies because of the widespread geographical distribution of rivers basins from mountainous terrain to flood plains, the low lying coasts and deltas. Pakistan is also a country which faces flood hazard periodically. The Indus river basin is the main flood prone area which occupies two-third area of .... Click Here to read more |

| Direct-Global and Reverse-Global Aspects of Town-wise Distribution of Karachi Katchi-Abadies |
From the administrative point of view previously Karachi was divided in five districts which is now divided in eighteen towns. This change over has greatly altered the distribution pattern of KKAs. So it seems necessary to analyze the situation anew. This study analyses the distribution of 200 KKAs in this new scenario. There are two aspects of these analyses the local and the global. The local aspect refers to the mutual relationship of KKAs in a town whereas; the global aspect refers to the relationship of a KA of a town with the KAs of all the other... Click Here to read

| Effect of Wet Cupping Therapy on Virulent Cellulitis Secondary to Honey Bee Sting – A Case Report |
| Cellulitis is clinical condition that is caused by the inflammation of sub-cutaneous tissue. Conventional treatment of cellulitis is based on the use of antimicrobials. Treatment by Cupping is one of the oldest ways of healing for more than 5000 years; now reemerging in this modern age and is being practice in many countries such as USA, UK, Germany and China.
This is the first reported case in which, twice a healthy subject was stung by honeybee and ... Click Here to read

| Studies of Ketoprofen Toxicity in Avian Species |
| Certain environmental factors are very important to stabilize the wild life; avian diseases, vulture crises and ecological annoyance. This should be fixed scientifically to minimize the health hazards. Thus; we have aimed this project to evaluate effects of toxic dosage levels of Ketoprofen in broiler chickens. Two hundred and twenty five (225) healthy broiler chickens were reared upto 28 days and divided into five groups 25 birds in .... Click

| The Effect of Cedrus deodara Root Oil on the Histopathology of Rat Stomach |
| The aim of this study was to observe the anti-ulcer effects of Cedrus deodara root oil on the rat’s stomach and compare it with standard anti-ulcer drugs, femotidine and protonix. The study was conducted on 50 albino Wistar rats in three different doses i.e. 30, 40, and 50 mg/kg. The animals were divided into five groups, each group comprised of 10 rats (5 male and 5 female). The oil was extracted from the plant root by dry destructive distillation method and the dose was calculated by dissolving 1.25 gms of Cedrus deodara in 25ml of 10% ethanol. The drugs were administered to the treated animals orally through .... Click

Design and Construction of Very Low Frequency Antenna |
| Communication with submerged submarines requires specific techniques and devices which gives totally different criteria as compared to the air. In the ocean salts water provide a hindrance for electromagnetic radiation such as normal radio communication because sat water acts as thick conductors. It is the normal practice in submarine is to surface and raise an antenna above the water surface to use standard technology. In case of nuclear-powered submarines it is very difficult to come on surface for communication. A thorough research it was analyzed by the scientists that VLF radio waves (3-30 KHz) can penetrate sea water down to a depth of roughly .... Click

| Total Global and Diffuse Solar Radiation for Upper Sindh, Pakistan |
| Global and diffuse solar radiation studies have been carried out for upper Sindh (Jacobabad) to assess the applicability of solar energy utilization for these areas. The global and diffuse solar radiation was carried out using sunshine hour data. The result obtained shows the variation of direct and diffuse component of solar radiation in summer and winter months. In Jacobabad areas the diffuse radiations is maximum during the month of July and August and minimum during the months of November, December and January. The cloudiness index...Click

| Utilization of Markov Chain Technique to Generate High-Density Wind Speed Data for the Coastal Belt of Pakistan |
| In order to estimates the reliable wind potential of any region, the high density wind speed data of 10-minutes or an hour interval is necessary. In most part of the Pakistan, available wind speed data is usually consists of monthly averages. In such a case, the Markov chain method based on transition matrix approach is used to synthesize the hourly wind speed data from the available averaged monthly wind speed data. The coastal belt of Pakistan is consider as a favorable regime for the .... Click

| Adverse Effect of Lead Acetate on Drosophila melanogaster |
| As lead is an important environmental noxious waste which directly or indirectly contaminate the foods, soil water, and air thus, insects could be influenced easily by the lead. Therefore, lead was studied as lead acetate in different doses. viz 0.125 mg., 0.25 mg., 0.5 mg, 01 mg and 02 mg, on external morphology on Drosophila melanogaster at 48 hours post treatment. It was observed that under the effects of lead abnormalities and deformity were developed in the larvae .... Click

| Correlation between Body Weight & Egg Weight of Dokki and Fayoumi Hen in Pakistan |
| Dokki & Fayoumi hens were studied for their egg production and feed consumption features. Feed consumption of 101.67 and105.4 gram per day per Dokki & Fayoumi hens bird was observed in the under test poultry from 20th to 40th weeks of age. In Dokki breed, the total egg production was recorded as 47.2% and average number of egg per hen was 66.2%. In this type an average increased egg weight was found from 39.2g to 45.9g. An average body weight gain during the 20th to 40th week of age was observed as 0.67kg. The survival/viability was 93.74% under the test conditions. On the other hand in Fayoumi breed, total egg production was.... Click

| Determination of LC50 of Chlorpyrifos and Neem Extract on third Instar Larvae of House Flies and their Effect on Fecundity |
| Two pesticides one from OP compound (Chlorpyrifos) and other from Biopesticides (Neem extract) were applied against 3rd instar larvae of house flies by contact method. LC50 of Chlorpyrifos and Neem extract was calculated as 0.25% for chlorpyrifos and 0.42% for Neem Extract. Treated larvae when succeeded to reach the adult stage, the effects of the .... Click
