Experiment was conducted to determine the effect of different nitrogen levels on four bread wheat varieties (Triticum aestivum L.) viz. Inqilab-91, Daman-98, Dera-98 and Punjab-96 at Gomal University, Dera Ismail Khan (NWFP), Pakistan during 2000 approximatey 2001. The experiment was laid out in split plot design having four replications using a net plot size of 2 m x 5 m. Nitrogen doses used were 0, 50, 100, 150 and 200 kg/ha. The results showed that different nitrogen levels had significant effects on plant height, total number of plants/m(2), number of grains/spike, number of spike/m(2), spike weight, biological yield, grain yield and grain protein content. Maximum plant height, total number of plants/m(2), number of spikes/m(2), spike weight, biological yield and grain protein content were observed at 200 kg N/ha. Among wheat varieties Daman-98 had maximum plant height, spike weight, grains/spike, 1000-grain weight, biological yield and grain yield. Inqilab-91 had heavier grains and the most grain protein content, while Dera-98 had the maximum plant population and spikes/m(2). Grain yield and biological yield were statistically similar at doses of 150 kg N/ha and 200 kg N/ha. However, dose of 200 kg N/ha, compared to dose of 150 Kg N/ha, significantly increased the protein content.

Congenital insensitivity to pain with anhidrosis is a rare autosomal recessive disorder presenting with loss of pain sensation, thermal sensation defects, and self-mutilating behavior. In the present study, we recruited two consanguineous pedigree showing pain insensitivity symptoms from Pakistan for clinical and molecular investigations. In family A, one female patient displayed classical CIPA symptoms along with microcephaly and severe intellectual disability. During course of the disease, her right foot was amputated and had remarkable dental degeneration and teeth shedding. In family B, one boy presented with classical symptoms of congenital insensitivity to pain with anhidrosis. Blood was collected from both families for molecular studies. Sequencing with the Ilumina Trusight One Sequencing Panel covering 4813 OMIM genes revealed a known homozygous mutation c.2084C>T; p.P695L of NTRK1 in family A and a novel truncated mutation c.2025C>G; p.Y681X in family B. Protein modeling analysis of both mutations (p.P695L and p.Y681X) predicted loss of the rigidity in tyrosine kinase domain of NTRK1 that led to conformational changes as well as deleterious effect on protein function. The known mutation was reported more than a decade ago in a family from Northern Israel and other non-sense mutation is newly identified. It is interested that most of NTRK1 mutations are associated with this domain. This is first ever report of NTRK1 variants in congenital insensitivity to pain with anhidrosis patients from Pakistan.

PURPOSE: The goal of this study was to compare the knowledge and attitudes of pharmacy and medical students regarding adverse drug reactions (ADRs), as well as their perceptions of barriers to ADR reporting, in a Higher Education Commission-recognised Pakistani university. METHODS: A cross-sectional study was conducted among final-year pharmacy (n=91) and medical (n=108) students in Pakistan from June 1 to July 31, 2014. A self-administered questionnaire was used to collect the data. The responses of pharmacy students were compared to those of medical students. RESULTS: Pharmacy students had a significantly better knowledge of ADRs than medical students (mean+/-SD, 5.61+/-1.78 vs. 3.23+/-1.60; P<0.001). Gender showed a significant relationship to knowledge about ADRs, and male participants were apparently more knowledgeable than their female counterparts (P<0.001). The attitudes of pharmacy students regarding their capability to handle and report ADRs were significantly more positive than those of medical students (P<0.05). In comparison to pharmacy students, a lack of knowledge of where and how to report ADRs was the main barrier that medical students perceived to ADR reporting (P=0.001). CONCLUSION: Final-year pharmacy students exhibited more knowledge about ADRs and showed more positive attitudes regarding their capacity to handle and report ADRs than final-year medical students.

Traumatic brain injury (TBI) causes disability and death, accelerating the progression towards Alzheimer’s disease and Parkinson’s disease (PD). TBI causes serious motor and cognitive impairments, as seen in PD that arise during the period of the initial insult. However, this has been understudied relative to TBI induced neuroinflammation, motor and cognitive decline that progress towards PD. Neuronal ubiquitin-C-terminal hydrolase- L1 (UCHL1) is a thiol protease that breaks down ubiquitinated proteins and its level represents the severity of TBI. Previously, we demonstrated the molecular action of glia maturation factor (GMF); a proinflammatory protein in mediating neuroinflammation and neuronal loss. Here, we show that the weight drop method induced TBI neuropathology using behavioral tests, western blotting, and immunofluorescence techniques on sections from wild type (WT) and GMF-deficient (GMF-KO) mice. Results reveal a significant improvement in substantia nigral tyrosine hydroxylase and dopamine transporter expression with motor behavioral performance in GMF-KO mice following TBI. In addition, a significant reduction in neuroinflammation was manifested, as shown by activation of nuclear factor-kB, reduced levels of inducible nitric oxide synthase, and cyclooxygenase- 2 expressions. Likewise, neurotrophins including brain-derived neurotrophic factor and glial-derived neurotrophic factor were significantly improved in GMF-KO mice than WT 72 h post-TBI. Consistently, we found that TBI enhances GFAP and UCHL-1 expression and reduces the number of dopaminergic TH-positive neurons in WT compared to GMF-KO mice 72 h post-TBI. Interestingly, we observed a reduction of THpositive tanycytes in the median eminence of WT than GMF-KO mice. Overall, we found that absence of GMF significantly reversed these neuropathological events and improved behavioral outcome. This study provides evidence that PD-associated pathology progression can be initiated upon induction of TBI.
