The most prevalent diagnostic test was ultrasound (96%) and most recommended medicine was tamsulosin (80%).

Regenerating tissue must initiate the signaling that drives regenerative growth, and sustain that signaling long enough for regeneration to complete. How these key signals are sustained is unclear. To gain a comprehensive view of the changes in gene expression that occur during regeneration, we performed whole-genome mRNAseq of actively regenerating tissue from damaged Drosophila wing imaginal discs. We used genetic tools to ablate the wing primordium to induce regeneration, and carried out transcriptional profiling of the regeneration blastema by fluorescently labeling and sorting the blastema cells, thus identifying differentially expressed genes. Importantly, by using genetic mutants of several of these differentially expressed genes we have confirmed that they have roles in regeneration. Using this approach, we show that high expression of the gene moladietz (mol), which encodes the Duox-maturation factor NIP, is required during regeneration to produce reactive oxygen species (ROS), which in turn sustain JNK signaling during regeneration. We also show that JNK signaling upregulates mol expression, thereby activating a positive feedback signal that ensures the prolonged JNK activation required for regenerative growth. Thus, by whole-genome transcriptional profiling of regenerating tissue we have identified a positive feedback loop that regulates the extent of regenerative growth.

A novel extracellular laccase enzyme produced from Spirulina platensis CFTRI was purified by ultrafiltration, cold acetone precipitation, anion exchange and size exclusion chromatography with 51.5% recovery and 5.8 purification fold. The purified laccase was a monomeric protein with molecular mass of ~66 kDa that was confirmed by zymogram analysis and peptide mass fingerprinting. The optimum pH and temperature of the enzyme activity was found at 3.0 and 30°C using ABTS as substrate but the enzyme was quite stable at high temperature and alkaline pH. The laccase activity was enhanced by Cu+2, Zn+2 and Mn+2. In addition, the dye decolorization potential of purified laccase was much higher in terms of extent as well as time. The purified laccase decolorized (96%) of anthraquinonic dye Reactive blue- 4 within 4 h and its biodegradation studies was monitored by UV visible spectra, FTIR and HPLC which concluded that cyanobacterial laccase can be efficiently used to decolorize synthetic dye and help in waste water treatment.

Objective: To assess factors related to workplace satisfaction of nursing care providers employed at different tertiary care hospitals of Karachi and to analyze the effect of demographic characteristics on satisfaction factors. Subjects and Methods: A cross-sectional study was conducted at different tertiary care hospitals of Karachi. Two hundred nursing care providers filled the standardized Nursing Workplace Questionnaire selected through convenient sampling method from February 2010 to May 2011. Results: The overall satisfaction score was 56.05 ± 6.812. Pleasure with job, mental relaxation, workplace communication, workplace learning environment, workplace support and workplace dependency were the most important factors describing satisfaction of nursing care providers. Females and unmarried respondents had less workplace support. Those having lower salary enjoyed and were pleased with job more than those who had higher salary. Younger respondents were less satisfied with workplace. Therefore, they had significantly lower scores of enjoyment, job satisfaction and pleasure with job. Participants with higher degree were less satisfied, enjoyed and pleased with job and also had less workplace communications. Conclusion: It was concluded that workplace support caused highest positive impact on job satisfaction and positive perception with colleagues with healthier workplace learning.

High fatty acid (FA) flux is associated with systemic insulin resistance, and African-American (AA) women tend to be more insulin resistant. We assessed possible depot and race difference in the antilipolytic effect of insulin in adipocytes isolated from abdominal (Abd) and gluteal (Glt) subcutaneous (sc) adipose tissue of overweight, postmenopausal AA and Caucasian (C) women. Percent body fat, fasting insulin, visceral adiposity, and adipocyte size was higher in AA women. Disinhibited lipolysis (presence of adenosine deaminase) per unit adipocyte surface area was similar in Abd and Glt and in AA and C. However, rates of 'basal’ [submaximal phenylisopropyl adenosine (PIA)-suppressed] and insulin-suppressed lipolysis were higher in Abd of AA compared with C women even after adjustment for percent fat and visceral fat area. The race difference in rates of PIA- and insulin-suppressed lipolysis in AA were correlated with their hyperinsulinemia, but AA race, independent of fasting insulin, was associated with lower responsiveness (percent suppression) to submaximal insulin concentrations, although sensitivity (ED50) was not affected. Overall, these data are consistent with the hypothesis that decreased responsiveness of Abd adipocytes to antilipolytic effectors may contribute to higher FA availability and thereby to racial differences in insulin resistance.

Genomic and proteomic studies have helped improve our understanding of the underlying mechanism(s) of cancer development and progression. Mutations, overexpressed oncogenes, inactivated/downregulated tumor suppressors, loss of apoptosis, and dysregulated signal transduction cascades are some of the well-studied areas of research. Resveratrol has gained considerable attention in the last two decades because of its pleiotropic anticancer activities. In this review, we have summarized the regulation of WNT, SHH (sonic hedgehog)/GLI (glioma-associated oncogene homolog), TGFβ1 (transforming growth factor beta 1)/SMAD, NOTCH, TRAIL (tumor necrosis factor-related apoptosis-inducing ligand), STAT (signal transducer and activator of transcription), and microRNAs by resveratrol in different cancers. The importance of these signaling pathways in cancer progression, along with their modulation by resveratrol, is discussed. Further, we also evaluate the mechanisms and implications of the downregulation of oncogenic miRNAs and the upregulation of tumor suppressor miRNAs by resveratrol, both of which also define its ability to inhibit tumor growth and metastasis. It is envisioned that designing effective clinical trials will be helpful for the identification of resveratrol responders and non-responders and the elucidation of how this phytochemical can be combined with current therapeutic options to improve their clinical efficacy and reduce off-target effects.

The physicochemical parameters and trace metal contents of water samples from Delhi were assessed. A total of 20 water samples were collected from boring, tube well and hand pump and analyzed for the various physicochemical parameters like pH, conductivity, total dissolved solid, total alkalinity, Ca2+ and Mg2+ hardness, chloride ion, dissolved oxygen, biochemical oxygen demand, sulphate and heavy metal contents like Cu, Cr, Cd, Co, Zn and Ni. The results were compared with BIS standards for drinking water. The quality of water samples under study were within the maximum permissible limits. Therefore, the groundwater samples are fit for human consumption without prior treatment.

Background. There is growing awareness of the public health importance of mental well-being both in the general population and in specific groups. The well-being of health professionals is likely to influence the quality of the care they deliver. This study was carried out to examine the well-being of Pakistani healthcare professionals, and to evaluate the psychometric performance of the Warwick–Edinburgh Mental Well-being Scale (WEMWBS) in this population.Methods. A cross-sectional survey was carried out from June, 2013 to December, 2014 among 1,271 Pakistani health care providers (HCPs) working in seven different cities in Punjab province, Pakistan, to examine the acceptability, internal consistency, test-retest reliability and content and construct validity of the English version of the WEMWBS in a Pakistani population sample. All data were analyzed in SPSS v. 21.Results. Our analysis demonstrated unidimensional construct validity, high internal consistency (0.89) and test-retest reliability, good validity and easy readability of WEMWBS in our sample of Pakistani HCPs. The mean WEMWBS score was 48.1 (SD 9.4), which is lower than in the general population in other countries. Male HCPs scored significantly higher on the WEMWBS than their female counterparts (P < 0.05), and older respondents had higher scores.Conclusion. The WEMWBS appears acceptable for use in Pakistani HCPs, and findings from this study verify its validity and internal consistency for this population sample. Our respondents had lower well-being scores than those reported in general population surveys in the UK.

Pluronic L81 (PL81) inhibits fat absorption, and other Pluronic copolymers help overcome drug resistance in cancer cells. To understand how PL81 acts, we synthesized a radiolabeled analog, [14C]PL81, and showed that it was structurally similar to PL81 based on 1H NMR as well as mass spectrometric analysis. [14C]PL81 inhibited the secretion of chylomicrons (CMs), lipoproteins essential for fat absorption, by differentiated Caco-2 cells similar to PL81. Moreover, PL81 competed with the cellular uptake of [14C]PL81. Thus, [14C]PL81 and PL81 behave similarly in these physiologic assays. Uptake of [14C]PL81 by Caco-2 cells was concentration-, time-, and temperature-dependent and occurred mainly from the apical side. Intracellularly, it was assimilated in the cytosol. Cells excreted PL81 toward the apical side via a pathway partially sensitive to verapamil. Small amounts were secreted toward the basolateral side unassociated with CM, and this secretion was unaffected by the inhibition of CM assembly. Nonetheless, PL81 significantly inhibited the secretion of triacylglycerols (TGs) and phospholipids as part of CM. PL81-treated cells showed decreased activity of microsomal triglyceride transfer protein and accumulated more TGs, but not phospholipids, in their cytosol. We propose that Pluronic copolymers act by interfering with the export of molecules from the cytosol. They inhibit fat absorption by decreasing TG transport to the endoplasmic reticulum and increase drug efficacy against cancer cells by competing for their excretion.

Objectives & Background: Good curriculum is reflected as the backbone for standard universities to develop competitive professionals having great potential. Pharmacy education in Pakistan has gone through the same developmental stages as in other countries, but is still striving for improvement. In the present study, we want (i) to know the opinion on whether the current pharmacy curriculum requires any improvement in order to meet the training needs of pharmacy professionals regarding clinical knowledge and pharmacy practice; and (ii) to present some humble suggestions to decision-making authorities in order to improve it with respect to patient-focused programs (PFP). Methods: The study was conducted in two sessions. In first session, a questionnaire was distributed to pharmacy students of eight public/private sector universities of Karachi (N = 354) offering Pharm. D degrees. The second session dealt with the pharmacy teachers, deans, and practicing pharmacists in health care facilities (who are in any ways also related to academia), in order to take their opinions on and suggestions for the development of a better Pharm. D curriculum (N = 135). Results: Our results showed that 75.2% of respondents agree that the Pharm. D curriculum does not meet the international standards of practice, and 88.4% of respondents support the addition of more clinical aspects than industrial ones, as Pharm. D could be both clinically and industrially oriented, according to the needs of the Pakistani people. Furthermore, 80.2% of respondents are of the view that an apprenticeship should be included in last two years, while 88.4% demand a ‘paid residency program’ to facilitate the hospital, clinical and compounding areas of pharmacy. In addition, we also received a number of verbal suggestions for improving the Pharm. D curriculum being followed in Pakistan. Discussion & Conclusions: We conclude that our Pharm. D curriculum needs additions in terms of clinical practice by providing residencies and electives in health care settings. Accordingly, the need for a clinically oriented curriculum is highlighted in Pakistan, keeping in mind the continuing importance of the industrial viewpoint. Various studies have criticized the pharmacy curriculum in Pakistan in the past. Conversely, we suggest some changes in the curriculum, as change is always needed for a better tomorrow.

The ability of Adulsa leaves powder (ALP) to adsorb Hg(II) from aqueous solutions has been investigated through batch experiments. The ALP biomass was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. The experimental parameters that were investigated in this study included pH, adsorbent dosage, and effect of contact time along with initial metal ion concentration. The adsorption process was relatively fast, and equilibrium was achieved after 40 min of contact time. The maximum removal of Hg(II), 97.5% was observed at pH 6. The adsorption data were correlated with Langmuir, Freundlich, and Temkin isotherms. Isotherms results were amply fitted by the Langmuir model determining a monolayer maximum adsorption capacity (qm) of ALP biomass equal to 107.5 mg g−1 and suggesting a functional group-limited sorption process. The kinetic process of Hg(II) adsorption onto ALP biomass was tested by applying pseudofirst-order, pseudosecond-order, Elovich, and intraparticle-diffusion models to correlate the experimental data and to determine the kinetic parameters. It was found that the pseudosecond order kinetic model for Hg(II) adsorption fitted very well. The rate determining step is described by intraparticle diffusion model. These studies considered the possibility of using Adulsa plant leaves biomass as an inexpensive, efficient, and environmentally safe adsorbent for the treatment of Hg(II) contaminated wastewaters.

PURPOSE: To determine normal macular thickness and its variation by age and gender in healthy eyes using spectral-domain optical coherence tomography (SD-OCT). METHODS: In this cross-sectional analysis, two hundred and twenty eyes of 220 healthy subjects underwent raster scanning using Topcon SD-OCT system, at the Department of Ophthalmology, Dow University of Health Sciences and Civil Hospital Karachi, Pakistan. Macular thickness from all 9 regions of the ETDRS map was documented for each subject. Variations in macular thickness measurements by age and gender were determined. RESULTS: The 220 subjects had a mean age of 45.3 years (16-80 years). Using the ETDRS map, foveal thickness for all subjects was measured to be 229±20.46 µm. Mean macular thickness for all subjects was 262.8±13.34 µm. Male gender was associated with greater foveal (p0.05) and foveal thickness (r(2) = 0.00004; p>0.05) with age. CONCLUSION: We have provided normative data for macular thickness using Topcon SD-OCT system. Our results are comparable to some and vary from other reports using the similar OCT system. Our results suggest that male gender is associated with greater macular thickness, while macular thickness has no association with age in healthy eyes. This is the first normative data for macular thickness from Pakistan; benchmark for diagnosing and monitoring macular pathologies. The values obtained in this study may be useful for comparison with other populations, other SD-OCT systems and future imaging technologies.
