Cloned Microglias With Novel Delivery System In Multiple Sclerosis, Abdul Mannan Baig Dr.
Department of Biological & Biomedical Sciences
Multiple Sclerosis (MS) is a chronic inflammatory neurological disease of the Central Nervous System (CNS), characterized by demyelination and activation of microglia. Mitochondrial mutations and dysfunctions in microglial cells are thought to contribute to the detrimental effects of neuroinflammation seen in MS. The Somatic Nuclear Transfer (SCNT) technology offers a more practical mode of therapy in MS, this method would attempt to dilute and/or progressively replace the mutated and activated microglia with cloned Olfactory Ensheathing Cells (OEC) with remyelinating and scavenging properties which would attempt to limit the progression of MS. Applying SCNTderived Embryonic Stem (ES) cells based therapy by …

Low Doses Of Colony-Stimulating Factors Lead To Resolution Of Neutropenia In Cancer Patients Through Increased Levels Of Dihydrofolate Reductase, Mohammad Perwaiz Iqbal, Ikram Ali Burney
Department of Biological & Biomedical Sciences
Low doses of granulocyte- colony stimulating factor (G-CSF) and granulocyte macrophage- colony stimulating factor (GM-CSF) have been shown to be beneficial in reducing duration of systemic antibiotic therapy and in-patient hospitalization by decreasing the period of neutropenia in cancer patients undergoing chemotherapy. Since the underlying mechanism is unclear, the aim of this study was to investigate whether the administration of G-CSF and GM-CSF in two different doses (low dose and standard dose) would result into resolution of neutropenia with concomitant increase in multiple forms of dihydrofolate reductase (DHFR, a pivotal enzyme in the pathway of de novo DNA synthesis). Thirty …
Trans Fatty Acids – A Risk Factor For Cardiovascular Disease, Mohammad Perwaiz Iqbal
Trans Fatty Acids – A Risk Factor For Cardiovascular Disease, Mohammad Perwaiz Iqbal
Department of Biological & Biomedical Sciences
Trans fatty acids (TFA) are produced either by hydrogenation of unsaturated oils or by biohydrogenation in the stomach of ruminant animals. Vanaspati ghee and margarine have high contents of TFA. A number of studies have shown an association of TFA consumption and increased risk of cardiovascular disease (CVD). This increased risk is because TFA increase the ratio of LDL cholesterol to HDL cholesterol. Food and Agriculture Organization of the United Nations and World Health Organization have come up with the recommendation that the contents of TFA in human dietary fat should be reduced to less than 4%. There is high …
Galectin-1 In Early Acute Myocardial Infarction, Suhail Al-Salam, Satwat Hashmi
Galectin-1 In Early Acute Myocardial Infarction, Suhail Al-Salam, Satwat Hashmi
Department of Biological & Biomedical Sciences
Myocardial infarction (MI) is the most serious manifestation of coronary artery disease and the cause of significant mortality and morbidity worldwide. Galectin-1(GAL-1), a divalent 14.5-kDa protein, is present both inside and outside cells, and has both intracellular and extracellular functions. Hypoxia inducible factor-1 alpha (HIF-1α) is a transcription factor mediating early and late responses to myocardial ischemia. Identification of the pattern of expression of GAL-1 and HIF-1α in the heart during the first 24 hours following acute MI will help in understanding early molecular changes in this event and may provide methods to overcome serious complications. Mouse model of MI …

Department of Biological & Biomedical Sciences
This study was aimed at providing the pharmacological basis for the medicinal use of Rhus coriaria in diarrhea. In mice, the crude of R. coriaria demonstrated antisecretory and antidiarrheal effects against castor oil-induced fluid accumulation and diarrhea at at 100 and 300 mg/kg, respectively, and was found safe up to tested dose of 5 g/kg. In isolated rabbit jejunum, R. coriaria exhibited concentration-dependent (0.01-3.0 mg/mL) relaxation of spontaneous and high K+ (80 mM)-induced contractions, similar to verapamil. The Ca++ antagonist activity was confirmed when pretreatment of R. coriaria shifted Ca++ concentration-response curves to the right with suppression …

Gossypiboma Diagnosed Fifteen Years After A Cesarean Section: A Case Report, Abdul Rehman, Noor Ul-Ain Baloch, Muhammad Awais
Department of Biological & Biomedical Sciences
Gossypiboma, a retained surgical sponge, is a rare complication following any surgical procedure and is primarily a result of human error. Such patients often have vague clinical presentations and the diagnosis often comes as a surprise. We present the case of a 40-year-old woman who had a long-standing history of lower abdominal discomfort. She was diagnosed with a gossypiboma fifteen years after a cesarean section. All general physicians, surgeons and radiologists must be aware of this rare but clinically significant entity.

Culturable Aerobic And Facultative Anaerobic Intestinal Bacterial Flora Of Black Cobra (Naja Naja Karachiensis) In Southern Pakistan, Junaid Iqbal, Mehwish Sagheer, Nazneen Tabassum, Ruqaiyyah Siddiqui, Naveed Ahmed Khan
Department of Biological & Biomedical Sciences
Using morphological analysis and biochemical testing, here for the first time, we determined the culturable gut bacterial flora (aerobes and facultative anaerobes) in the venomous Black Cobra (Naja naja karachiensis) from South Asia. The findings revealed that these snakes inhabit potentially pathogenic bacteria including Serratia marcescens, Pseudomonas aeruginosa, Shewanella putrefaciens, Aeromonas hydrophila, Salmonella sp., Moraxella sp., Bacillus sp., Ochrobactrum anthropi, and Providencia rettgeri. These findings are of concern, as injury from snake bite can result in wound infections and tissue necrosis leading to sepsis/necrotizing fasciitis and/or expose consumers of snake meat/medicine in the community to infections.
