Role of serum procalcitonin level in early diagnosis of bacterial pneumonia in children, a hospital based study
Background: Procalcitonin (PCT) is a precursor of hormone calcitonin. It is composed of 116 amino acids and is produced by para follicular C cells of the thyroid and by neuroendocrine cells of lungs and intestine. The level of Procalcitonin in healthy individuals is below the limit of detection (0.01µg/L).These levels may rise from extra thyroid tissues especially in response to inflammatory stimulus of bacterial origin. PCT has the greatest sensitivity and Specificity for differentiating patients with sepsis from those with systemic inflammatory response syndrome. And the objective of the study is to discuss the method for early diagnosis and use of antibiotic therapy in patients of bacterial pneumonia.Methods: A hospital based study was conducted in our hospital from January 2015 to June 2015. Eighty six children with severe pneumonia were enrolled from Department of Paediatrics and were divided into two groups according to bacteriological detection; bacterial pneumonia group consisting of 44 children patients and non-bacterial pneumonia group of 42 children patients. Meanwhile, 45 healthy children were also enrolled and grouped into normal control group. Chest X-ray and Peripheral venous blood of all children was collected to detect complete blood count, CRP and procalcitonin (PCT).Results: Serum PCT level of patients with bacterial pneumonia was significantly higher than that in the non-bacterial pneumonia patients and normal controls ; serum PCT level of patients with bacterial pneumonia, before and after treatment had statistical significance ; Serum PCT level of patients with non-bacterial pneumonia had no statistical significance before and after treatment .Conclusions: Serum PCT is an important biomarker for prompt diagnosis of bacterial infection and a sensitive indicator to distinguish bacterial from non-bacterial pneumonia. Evaluating serum PCT levels helps in early use of antibiotic therapy and prognosis of underlying disease.
Fuzzy decision making in Business intelligence in the context of Gilgit-Baltistan
The main purpose of this paper is to investigate and implement fuzzy decision based on unequal objectives and minimization of regret for the decision making in the business intelligence and to compare the weight of products while the minimization of regret that uses regression of products in Gilgit-Baltistan. Here we will convert the verbal expressions in to linguistic variables and use in fuzzy decision making model, which influences the main two factors, one is effect of the influence on the product and second its payoff for the most effectiveness on the products
Comparative Analysis of V-Akt Murine Thymoma Viral Oncogene Homolog 3 (AKT3) Gene between Cow and Buffalo Reveals Substantial Differences for Mastitis
AKT3 gene is a constituent of the serine/threonine protein kinase family and plays a crucial role in synthesis of milk fats and cholesterol by regulating activity of the sterol regulatory element binding protein (SREBP). AKT3 is highly conserved in mammals and its expression levels during the lactation periods of cattle are markedly increased. AKT3 is highly expressed in the intestine followed by mammary gland and it is also expressed in immune cells. It is involved in the TLR pathways as effectively as proinflammatory cytokines. The aims of this study were to investigate the sequences differences between buffalo and cow. Our results showed that there were substantial differences between buffalo and cow in some exons and noteworthy differences of the gene size in different regions. We also identified the important consensus sequence motifs, variation in 2000 upstream of ATG, substantial difference in the “3′UTR” region, and miRNA association in the buffalo sequences compared with the cow. In addition, genetic analyses, such as gene structure, phylogenetic tree, position of different motifs, and functional domains, were performed to establish their correlation with other species. This may indicate that a buffalo breed has potential resistance to disease, environment changes, and airborne microorganisms and some good production and reproductive traits

Mucinous carcinoma of breast: A rare tumour with favorable prognosis - 10 years experience from a single center
Purpose: The purpose of this study was to describe the biological behaviour of mucinous breast carcinoma (MBC) regarding their clinical presentations, pathological features, prognosis and survival.Methodology: We conducted this retrospective study from 2006 to 2015 (10-year duration) and included all the patients who presented with mucinous carcinoma of the breast at any age. We excluded all the patients who presented with invasive ductal carcinoma or other rare breast tumours. Each patient with mucinous carcinoma breast was categorised in terms of diagnosis, surgery, chemotherapy and outcome. For categorical variables, Chi-square test was used. Kaplan–Meier curves were used to determine estimated overall survival. Data analysis was carried out using the SPSS 20.Results: In total, 8841 patients with breast carcinoma presented during the study period. Of these, 74 patients were diagnosed as cases of MBC, constituting <1%. Family history of breast carcinoma was positive in 20% of patients. Most of the women were postmenopausal (66.2%) falling in BIRADS Category 4 and 5 (32.4% each). Considering laterality tumours had almost equal distribution between the right and left side. Breast-conserving surgery was performed in 47.3% of women as compare to modified radicle mastectomy in 52.7% of women. Most of the patients had pathological T2 (51.4%), N0 (81.1%) and moderately differentiated (69%) mucinous carcinoma. ER was positive in 85% of patients, PR in 80% and H2N in 74.6% of patients. Neoadjuvant chemotherapy was given to 20 patients (27%) and adjuvant chemoradiotherapy was given to 51 patients (69%). Metastasis occurred in 12 (16.2%) of our patients while 62 (83.8%) were metastasis free on long-term follow-up, with bones being the most common site of metastasis, occurring in 6 patients (8.1%) followed by lungs, occurring in 4 patients (5.4%). A total of 32 (43.2%) patients are alive, and on regular follow-up, 3 (4.1%) died during the course of follow-up and 39 (52.7%) are lost to follow-up with a median survival of 60 months and an overall 5-year survival rate of >95%.Conclusion: Mucinous carcinoma is a rare breast carcinoma with a good prognosis.Key words: Breast cancer, mucinous carcinoma, prognosi
Graphene oxide incorporated polyether sulfone nanocomposite antifouling ultrafiltration membranes with enhanced hydrophilicity
In this study, the polyether sulfone (PES) based membranes containing various concentrations of graphene oxide (GO), polyvinylpyrrolidone (PVP), and polyethylene glycol (PEG) were synthesized via the phase immersion method. This study aims to evaluate the effect of GO addition on the structural properties and performance of the membranes. The membranes were analyzed by x-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transforms infrared spectroscopy (FTIR). The FTIR-ATR spectra indicated the presence of hydroxyl and carboxylic acid groups on the surface of GO-incorporated membranes, which improved their dispersion in the polymeric matrix and hydrophilicity. The SEM analysis of the GO-containing PES membranes confirmed the formation of a well-defined finger-like porous structure presenting adequate water flux (95 l.m(-2).h(-1)) and salt rejection (72%) compared to the pristine PES membranes (46 l.m(-2).h(-1) and similar to 35%, respectively). In addition, the significantly large wettability and considerably improved antibacterial characteristic (against S. aureus and E. coli strains) of the GO-PES membranes are considered impressive features.National University of Sciences and Technology (NUST) Research Directorate; HEC; NRPU [6020]6020; Higher Education Commission, Pakistan, HEC; National University of Sciences and Technology, NUS
