The goal of this research is to look into the relationship between social media marketing activities and brand attachment in the online marketing business, based on the indirect effect of perceived value and self-brand connections. For this reason, the study has used self-administered questionnaires to collect the data from 425 males from the major cities of Pakistan including Islamabad, Karachi, Lahore, and Sialkot. Furthermore, based on the PLS-SEM technique the empirical findings show that social media marketing activities positively affect perceived value, self-brand connections, and brand attachment. Perceived value has a significant positive impact on brand attachment and mediates the influence of social media marketing activities on brand attachment. In addition to this, self-brand connections have a positive effect on brand attachment, and self-brand connections mediate the relationship between them. Thus, firms employing social media marketing activities successfully in their branding build upon a positive perception of the brand in the customer's mind resulting in customer attachment with the brand. This study can assist the e-commerce managers and brand managers in building strong customer attachment via perceived value and self-brand connections.

Objective: Hyperketonemia remains a major metabolic issue of serious milk production and a major health concern in early lactation cows. Oral supplementation of glucose precursors (GP) can be used to prevent hyperketonemia in dairy cows. The objective of this study was to compare the beneficial effects of orally supplementing a mixture of GP on metabolic health indicators and milk production status of primiparous (PP) and multiparous (MP) dairy cows. Methods: Twenty-eight Holstein cows were blocked by expected date of parturition, previous lactation yield, and parity. The cows were randomly allocated to one of the four treatment groups (n = 7 cows/group) based on their parity and GP supplementation: i) PP cows fed basal diet only (PP-CON), ii) PP cows with oral supplementation of GP (PP-GP), iii) MP cows fed basal diet only (MP-CON), and iv) MP cows with oral supplementation of GP (MP-GP). Glucose precursor (glycoline liquid) was orally drenched (300 mL/d) in GP cows from 7 days prepartum through 7 days postpartum. Other than GP supplementation, all cows were fed similar pre- and postpartum basal diets. Results: In both pre- and postpartum periods, serum glucose concentration was increased, whereas β-hydroxybutyrate and free fatty acids were decreased in GP cows compared with the CON cows. Milk yield and milk components were statistically not different between GP and CON cows over the first 9 week of lactation. The yield of actual milk, energycorrected milk, 63-days cumulative milk, colostrum yield, and calf birth weight remained higher in MP cows compared with PP cows. Conclusion: Oral drenching of GP around calving can be recommended to successfully improve the metabolic health and reduce the negative effects of hyperketonemia not only in MP but also in PP dairy cows.

Ionic liquids due to their advantageous properties gain importance in many fields. This study aims tooverview the use of ionic liquids in the selective partial fluorination of organic compounds throughelectrochemical method. In addition to ionic liquid based fluorination, the earlier approaches offluorination through an electrochemical process have also been highlighted. The factors such aselectrode materials (Pt, Ni, and C), types of solvents (CH3CN, DMC, THF, DME, Sulfone, etc.) and type ofelectrolytes (Et3N 3HF, Et3NF 3HF, py HF, etc.) which affect the electrochemical fluorination of organiccompounds have been reviewed. For electrode preparation, the carbon, platinum and nickel wereconsidered suitable materials to be used as an electrode. In CH3CN media, Et3N 3HF and Et4NF 3HFshowed better efficiency during fluorination of organic compounds. Solvent play an important role inelectrochemical fluorination of organic compounds, with the change of solvent the percentage yield ishighly affected. Py-HF is a convenient solvent-supporting electrolyte medium with a reasonably goodconductivity. The electrolyte containing solvents have some side effects on electrochemical fluorinationof organic compounds as observed in cyclic voltammetric analysis. Therefore electrochemicalfluorination to organic compounds without the use of solvent gained more importance. The ionicliquids have been reported for its dual properties, as solvent as well as a fluorinating agent for organiccompounds in electrochemical processes. It has been concluded that solvents free electrochemicalfluorination of organic compounds gives good results as compare to solvent based. Ionic liquids due tomore oxidative stability were noted to have considerable effect on the yield and selectivity of organiccompound fluorination.

An Efficient Rif Algorithm for the Classification of Kantowski-Sachs Spacetimes via Conformal Vector Fields

Tahir Hussain,Uzma Nasib,Fawad Khan,Muhammad Farhan 한국물리학회 2020 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.76 No.4

In this paper, we classify the Kantowski-Sachs spacetimes via conformal vector fields (CVFs). A Maple algorithm using the `Exterior' package is used to reduce the set of conformal Killing equations to the reduced involutive form (Rif). The algorithm yields a tree, known as the Rif tree, where the branches of the Rif tree give the potential metrics for which the spacetimes under consideration may possess proper CVFs. The set of conformal Killing equations is solved for all the branches of the Rif tree to obtain the explicit forms of CVFs. Some physical implications of the obtained metrics are also discussed.

Enhancing Activity of Anticancer Drugs in Multidrug Resistant Tumors by Modulating P-Glycoprotein through Dietary Nutraceuticals

Khan, Muhammad,Maryam, Amara,Mehmood, Tahir,Zhang, Yaofang,Ma, Tonghui Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.16

Multidrug resistance is a principal mechanism by which tumors become resistant to structurally and functionally unrelated anticancer drugs. Resistance to chemotherapy has been correlated with overexpression of p-glycoprotein (p-gp), a member of the ATP-binding cassette (ABC) superfamily of membrane transporters. P-gp mediates resistance to a broad-spectrum of anticancer drugs including doxorubicin, taxol, and vinca alkaloids by actively expelling the drugs from cells. Use of specific inhibitors/blocker of p-gp in combination with clinically important anticancer drugs has emerged as a new paradigm for overcoming multidrug resistance. The aim of this paper is to review p-gp regulation by dietary nutraceuticals and to correlate this dietary nutraceutical induced-modulation of p-gp with activity of anticancer drugs.

Background Financial, clinical, and psychological considerations have made same-day surgery an attractive option for a variety of procedures. This article aimed to analyse the postoperative results of same-day primary unilateral cleft nasolabial repair. Methods This study was performed from 2011 to 2014. Unilateral cleft lip patients fulfilling the inclusion criteria were preoperatively classified as mild, moderate, and severe. All patients underwent same-day surgery and were discharged after satisfying the appropriate clinical criteria, receiving thorough counselling, and the establishment of a means of communication by phone. Postoperative outcomes were assessed and stratified according to preoperative severity and the type of repair. Results A total of 423 primary unilateral cleft lip patients were included. Fisher's anatomical subunit approximation technique was the most common procedure, followed by Noordhoff's technique. The postoperative outcome was good in 89.8% of cases, fair in 9.9% of cases, and poor in 0.2% of cases. The complication rate was 1.18% (n=5), and no instances of mortality were observed. The average hospital stay was 7.5 hours, leading to a cost reduction of 19% in comparison with patients who stayed overnight for observation. Conclusions Mild unilateral cleft lip was the most common deformity for which Fisher's anatomical subunit approximation technique was performed in most of the cases, with satisfactory postoperative outcomes. Refinements in the cleft rhinoplasty techniques over the course of the study improved the results regarding cleft nasal symmetry. Single-day primary unilateral cleft cheiloplasty was found to be a cost-effective procedure that did not pose an additional risk of complications.

This research examines the underlying mechanism through which corporate social responsibility (CSR) influences customer loyalty in the hospitality sector. A survey conducted in three popular tourist cities in China reveals that CSR positively impacts customer loyalty through institutional-level constructs, including corporate image and sustained competitive advantage, and individual-level constructs, including customer trust and customer satisfaction. Moreover, the core capabilities of organizations moderate the effect of CSR on corporate image and sustained competitive advantage. Corporate image sustained advantage, and customer satisfaction also mediates the relationship between CSR and customer loyalty. The theoretical and practical implications of these findings are discussed.

Rafia Mahmood,Saleem Ahmed Khan,Chaudhry Altaf,Hamid Saeed Malik,Muhammad Tahir Khadim 대한혈액학회 2018 Blood Research Vol.53 No.4

BackgroundChronic lymphocytic leukemia (CLL) exhibits profound heterogeneity in its clinical course. Its clinicohematological and cytogenetic features play a significant role in de-termining the clinical course and in predicting the treatment response and prognosis. In this context, 17p deletion is known to predict a poor prognosis, as these cases are re-fractory to conventional therapy. This study aimed to evaluate the clinicohematological characteristics, outcomes, and prognostic factors among CLL patients with and without del 17p in Pakistan.MethodsThis prospective observational study was conducted at the Department of Haematology, Armed Forces Institute of Pathology (Rawalpindi, Pakistan) between January 2013 and December 2017. Patients were diagnosed based on the International Workshop on Chronic Lymphocytic Leukaemia IWCLL criteria, their clinicohematological parameters were recorded, and cytogenetic analyses were performed. The time from diagnosis to treatment and the 2-year overall survival rate were also evaluated.ResultsWe evaluated 130 CLL cases, including 24 patients (18.5%) with del 17p, who included 18 men (75%) and 6 women (25%). The median age was 68 years. Binet stage C was de-tected at the presentation in 16 patients (67%). Treatment was administered to 14 patients (70%) at a median interval of 11 months (range, 0‒28 mo) after diagnosis. The overall response rate was 64.3%, the median event-free survival was 9 months (range, 1‒23 mo), and the 2-year overall survival rate was 65%.ConclusionDel 17p is relatively common in Pakistan, and patients harboring this deletion had poor treatment response and survival outcomes.

Association of the CYP17-34T/C Polymorphism with Pancreatic Cancer Risk

Hussain, Shahid,Bano, Raisa,Khan, Muhammad Tahir,Khan, Mohammad Haroon Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.no.sup3

Pancreatic cancer is a leading cause of fatality worldwide. Several population studies have been conducted on genetic diagnosis of pancreatic cancer but the results from epidemiologic studies are very limited. CYP17A gene has a role in disease formation but its influence on pancreatic cancer is unclear. A polymorphism in the 5'UTR promoter region of CYP17A1-34T/C (A1/A2) has been associated with multiple cancers. The aim of the current study was to assess associations of this polymorphism and socio-demographic risk factors with pancreatic cancer. A total of 255 and 320 controls were enrolled in the study, and were genetically analyzed through PCR-RFLP. Statistical analysis was conducted with observed genotype frequencies and odds ratios (ORs) and 95% CIs were estimated using unconditional logistic regression. The impact of socio-demographic factors was accessed through Kaplen-Meir analysis. According to our results, the A2/A2 genotype was significantly associated with pancreatic cancer (OR=2.1, 95%CI = 1.3-3.5). Gender female (OR=2.6, 95%CI=1.8-3.7), age group 80s/80+ years (OR=2.2, 95% CI=1.2-4), smoking both former (OR=4.6, 95% CIs=2.5-8.8) and current (OR=3.6, 95% CI=2-6.7), and family history (OR=7.1; 95%CI = 4.6-11.4) were also found associated with increased risk. Current study suggests that along with established risk factors for pancreatic cancer CYP17A1-34T/C may play a role. However, on the basis of small sample size the argument cannot be fully endorsed and larger scale studies are recommended.
