Gender and Ultimatum in Pakistan: Revisited

Razzaque (2009) studied the role of gender in the ultimatum game by running experiments on students in various cities in Pakistan. He used standard confirmatory data analysis techniques, which work well in familiar contexts, where relevant hypotheses of interest are known in advance. Our goal in this paper is to demonstrate that exploratory data analysis is much better suited to the study of experimental data where the goal is to discover patterns of interest. Our exploratory re-analysis of the original data set of Razzaque (2009) leads to several new insights. While we re-confirm the main finding of Razzaque regarding the greater generosity of males, additional analysis suggests that this is driven by student subculture in Pakistan, and would not generalise to the population at large. In addition, we find strong effect of urbanisation. Our exploratory data analysis also offers considerable additional insights into the learning process that takes place over the course of a sequence of games.

Comparison of protective effects of carvedilol and α-tocopherol on doxorubicin-induced cardiotoxocity

Background: Doxorubicin, an effective anticancer drug used to treat multiple solid tumours and childhood malignancies since many decades but its cardiac adverse effects limits its use in full therapeutic dose. The mechanism involved in cardiotoxicity is apoptosis of cardiomyocytes due to reactive oxidative stress. The study was conducted to compare the cardioprotective effects of carvedilol and α-Tocopherol and to detect myocardial injury at early stage.Methods: Cardiotoxicity was produced in a group of rabbits by single intravenous injection of doxorubicin; control group was treated with normal saline only. Third and fourth groups were pretreated with carvedilol 30 mg/kg bodyweight and α-Tocopherol 200 mg/kg bodyweight respectively for ten days before injection of doxorubicin.Results: Doxorubicin produced marked cardiotoxicity represented by raised levels of serum biomarkers (cTnI, LDH and CK-MB) and severe necrosis of cardiomyocytes on microscopic examination. Carvedilol and α-tocopherol pretreatment resulted in decreased serum levels of biomarkers and improved the histological picture of heart tissue.Conclusions: The outcome of doxorubicin chemotherapy can be made successful with the concurrent use of carvedilol or α-tocopherol. Although carvedilol has more pronounced cardioprotective effects perhaps due to its antioxidant activity in addition to antiapoptotic, antiproliferative and anti-inflammatory effects. Furthermore the quantitative cTnI estimation for detection of cardiotoxicity at early stage can lead to significant economic impact in management of cancer

Nitrofurantoin and Fosfomycin, effective oral empirical treatment options against multidrug resistant Escherichia coli

ObjectiveThe present study is designed to monitor antibiotic susceptibility pattern of Escherichia coli to assist in forecasting empirical therapy of urinary tract infection.MethodologyIt is a retrospective cross sectional study. It was carried out at Dow Diagnostic Research and Reference Laboratory for a period of 3 months from February 2017 to April 2017. A data of total 5000 urine culture and sensitivity test reports was taken from the medical record. The data was analyzed by SPSS version 16.ResultsOut of 5000 urine samples processed, 1565 showed significant bacterial growth. Escherichia coli was the most common pathogen isolated. Meropenem, Amikacin, Fosfomycin and Nitrofurantoin respectively were found to be the most sensitive antibiotics against Escherichia coli.Conclusion Fosfomycin and Nitrofurantoin are effective oral antibiotics against Escherichia coli causing urinary tract infection. The present study may help clinicians in making rational choice of empirical treatment of the patients

Perceptions and Performance of dental students using Conventional and Virtual Microscopy in Oral Pathology

Virtual microscopy for showing histopathological slides have been in use for quite some time. This method of teaching is considered to be a good replacement for conventional microscopy using glass slides. This study was carried out to analyze the perception and performance of dental students regarding the use of conventional microscopic slides and virtual slides in relation to teaching and learning. Material and methods: Eighty undergraduate dental students who had studies the subject of oral pathology as a compulsory subject at Watim Dental college were invited to participate in the study. Students not willing to take part in the study were excluded. The questionnaires were duly filled and test was taken by the students using either virtual slides or glass slides. The data was collected and analyzed using SPSS 20. Results: A total of eighty undergraduate students participated in the study. The results showed that dental students had a higher acceptance rate (all P-value<0.001) for cases taught via virtual microscopy and they out performed in cases shown on virtual slides (p<0.01). Conclusion: In this study the students preferred teaching of oral histopathology via virtual slides over conventional glass slides and it also contributed more to their learning.

Comparison of hepatoprotective effect of aqueous and ethanolic extracts of Berberis lycium Royale (Sumbloo) in isoniazid induced hepatotoxicity in male mice model

Background: The objective of the study was to compare the hepatoprotective effect of aqueous and ethanolic extracts of stem bark of Berberis lycium Royle in isoniazid (INH) induced hepatotoxicity in mice model.Methods: This randomized controlled in-vivo study conducted in male mice model from 10th April 2014 till 10th May 2014 at National Institute of Health, Islamabad. Group (C) was given normal diet and water. Group (D) was given isoniazid (50 mg/kg BW) to produce hepatotoxicity. Group (LA) and (HA) were given isoniazid (INH) plus low and high dose of aqueous extract of stem bark of Berberis lycium Royle respectively. Group (L.E) and (H.E) were given INH plus low and high dose of ethanolic extract of stem bark of Berberis lycium Royle respectively.Results: Hepatotoxicity produced by INH was shown by raised serum liver function tests (LFT’s), marked hepatocytic ballooning, significant steatosis and inflammation. Mice receiving simultaneous treatment of INH, low and high dose of aqueous extract of Berberis lycium Royle showed decrease serum LFT’s and their liver sections showed improved histological picture but more significant reduction in hepatotoxic effects were observed in animals receiving low and high doses of ethanolic extract.Conclusions: Hepatotoxicity of INH can be more fully reversed by simultaneous use of INH with ethanolic extract as it has better hepatoprotective potential in dose dependent manner as compare to aqueous extract of stem bark of Berberis lycium Royle

Dry Matter Degradation Kinetics of Selected Tropical Forage in Nili-Ravi Buffalo and Cholistani Cows at Heifer and Lactating Stages Using NorFor in Situ Standards

Current methods of ruminant ration formulation in Pakistan use foreign-based nutrient availability values. These values may not be optimal for all geographic areas, as variation in environment, agronomic factors, animal species, and diet characteristics may not be considered. The aim of present study was to establish a database of the chemical composition and dry matter degradation parameters of tropical forage commonly fed to ruminants in Pakistan and South Asian countries using Nili-Ravi buffalo and Cholistani cattle at heifer and lactating stages. Six cereal grain and four legume species were grown in 3 locations under standard agronomic conditions and sampled at booting and at 50% flowering stage for cereal and legumes, respectively. Dried and milled feeds were analyzed for chemical composition and in situ dry matter degradation parameters using 1 g samples in bags placed in the rumen of 2 Nili-Ravi buffalo heifers, 2 lactating Nili-Ravi buffaloes, 2 Cholistani heifers, and 2 lactating Cholistani cows. The forage family (cereal vs. legumes), species, and geographic location of growth significantly influenced (P 0.05). Legume-by-heifer interactions significantly increased (P < 0.05), and legume-by-lactating cow interaction tended (P = 0.065), to increase the rate of degradation (Kd). The selected forages were degraded to a similar extent independent of animal species or developmental stage, and legumes are degraded at higher rates and to a greater extent than are cereals. A moderately significant relationship between Kd and effective dry matter degradability (DMD) suggests that Kd could be the single most important predictor of forage degradability in the rumen
