Word-Picture Conjunction: A Multimodal Discourse Analysis of Cellular Network Companies Slogans in Pakistan

Word -picture conjunction is an effective mode of communication. Words cannot be understood without pictures and vice versa. The present study investigates how linguistic and meta-linguistic features of cellular network companies are employed to propagate desired ideology to the target audience to win their consent through discursive moves.  The data for the present research has been collected from Mobilink Jazz's slogans. The time span for data collection ranges from year 2015-16. The methodological perspectives used in the present research include Fairclough (1993) model of Critical Discourse Analysis, Barthes' (1974) model of Semiological Discourse Analysis and Kruger's (2000) model of Focus Group Discussion analysis. The data used in the study comprises three modes (linguistic, visual and views of focus group participants). This justifies the use of tri-angular research method employed in the study. The research contends that role of new media has increased communication among the people the world over. Additionally, it finds that new media is one of the best sites for ideological investment because significance of visual and verbal practices has increased many folds.</p

Probiotics supplementation reduces cigarette smoke-induced damage in the respiratory micro-architecture of mice

This study evaluated the protective efficacy of probiotics supplementation against cigarette smoke-induced lung emphysema, inflammation, and loss of cilia in mice. Probiotics are known to promote mucosal tolerance and mitigate respiratory injuries. Twenty-four adult mice were randomly divided into three groups: control (Ctr), cigarette smoke (CS), and cigarette smoke + probiotics (CS+P). Probiotics were given for 7 days before exposure to smoke in the CS+P group. Tissue samples of the trachea (goblet cell count and index, loss of cilia), lungs (airspace distention), and bronchoalveolar lavage fluid (BALF) were collected and processed. The results showed a significant increase in acidic and neutral goblet cells in the CS group compared to the Ctr and CS+P groups (P &lt; 0.05). Overall, goblet cell number and index were lower in the CS+P group (41.71 ± 5.76, 0.67 ± 0.073) than CS group (56.28 ± 5.34, 1.31 ± 0.28). Inflammatory cells and loss of cilia significantly decreased in mice fed probiotics before exposure to cigarette smoke (P &lt; 0.05). Lung emphysema was also significantly reduced in the CS+P group compared to the CS group (P &lt; 0.05). In conclusion, dietary supplementation of probiotics reduced lung emphysema, inflammatory cells, goblet cell index, and loss of cilia under conditions of cigarette smoke exposure in mice.O presente trabalho avaliou a eficácia da suplementação com probióticos contra a indução de enfisema, inflamação e perda de cílios por fumaça de cigarro em camundongos. Sabe-se que os probióticos promovem a tolerância da mucosa e mitigam as injúrias respiratórias. Vinte e quatro camundongos foram divididos, ao acaso, em três grupos: controle (CTR), fumaça de cigarro (CS) e fumaça de cigarro + probióticos (CS+P). Os probióticos foram fornecidos por sete dias antes da exposição à fumaça no grupo CS+P. Foram colhidas e processadas amostras de tecidos da traqueia (contagem de células caliciformes e index, perda de cílios), pulmões (distensão do espaço aéreo) e fluido de lavagem broncoalveolar. Os resultados obtidos revelaram um aumento significativo em células caliciformes acidificadas e neutralizadas no grupo CS quando comparado aos grupos Ctr e CS+P (P&lt;0,05). Os números global e o índice de células caliciformes foram menores no grupo CS+P (41,71+ 5,76; 0,67+ 0,073) que no grupo CS (56,28+ 5,34 e 1,131+ 0,28). As células inflamatórias e a perda de cílios decresceram em camundongos alimentados com probióticos antes da exposição à fumaça de cigarro (P&lt;0,05). O enfisema pulmonar também foi significativamente reduzido no grupo CS+P quando comparado ao grupo CS (P&lt;0,05). A conclusão obtida foi que o fornecimento de dieta suplementada com probióticos reduziu o enfisema pulmonar, as células inflamatórias, o índice de células caliciformes e a perda de cílios nos camundongos expostos à fumaça de cigarro

Effects of Iron Oxide Nanoparticle Supplementation on the Growth Performance, Serum Metabolites, Meat Quality, and Jejunal Basal Morphology in Broilers

Simple Summary: Iron is a necessary micronutrient in animal feed. Iron is an important component of hemoglobin, myoglobin, and the enzymes participating in redox reactions. The aim of the current study was to assess the effects of iron oxide nanoparticle supplementation on production performance, organ development, blood biochemistry, redox status, meat quality, and jejunal histology in broilers. The results indicated that iron oxide nanoparticle supplementation improved the feed conversion ratio, pectoral muscle, and jejunal histology. However, iron oxide nanoparticle supplementation showed no effects on visceral organ development, blood metabolites, redox status, and carcass traits. Abstract: The current research aimed to evaluate the supplemental effects of iron oxide nanoparticles (IONPs) on production performance, viscera development, blood metabolites, redox status, meat quality, and jejunal histology in broilers. A total of 300 day-old broilers were randomly divided into six groups with five replicates per group. Birds were fed on a corn soybean-based diet supplemented with 0, 20, 40, 60, or 80 mg/kg IONPs or 80 mg/kg of FeSO4 for 35 days. The feed conversion ratio (FCR) was improved in birds supplemented with 60 mg/kg IONPs. The pH24h was lower in birds supplemented with 40 mg/kg IONPs compared to that of the bulk group. Pectoral muscle fascicle diameter and fiber density were significantly increased in 20 mg/kg IONP-supplemented birds compared to those of the bulk group, respectively. The muscle fiber diameter was higher in 40 mg/kg IONP-supplemented birds compared with the bulk group. The jejunal villus height, crypt depth, and villus surface area were significantly increased with 60 mg/kg IONP supplementation, whereas villus width was decreased in birds supplemented with 40 mg/kg IONPs. The villus-height-to-crypt-depth ratio was lower in IONP-supplemented birds compared to the bulk group. IONP supplementation improved the FCR, jejunal, and pectoral muscle morphology without affecting the carcass characteristics and redox status of broilers

Effect of sodium butyrate on performance, immune status, microarchitecture of small intestinal mucosa and lymphoid organs in broiler chickens

Objective This study aimed to examine the effect of sodium butyrate (SB) on growth performance, immune status, organs weights, and microarchitecture of lymphoid organs and small intestine. Methods A total of 120, 1-d-old broiler chicks were distributed into the following four treatment groups: corn-soy based basal diet (BD) without supplement (control), or the same BD supplemented with 0.1 g/kg zinc bacitracin (ZnB), 0.5 g/kg SB (SB-0.5), or 1.0 g/kg SB (SB-1), respectively. Six birds/group were killed on d-21 and d-35, and samples were collected. Results Cell-mediated immune response at 48 h post-Phytohemagglutinin-P injection, and antibody titer against Newcastle disease vaccine and sheep red blood cells on d-35 was noted higher (p<0.05) in SB-1 compared to ZnB and control. Lower (p<0.05) feed conversion ratio (FCR) was attained by the supplemented groups. Thymus and spleen weighed more (p<0.05) in SB-1, and bursa registered more (p<0.05) weight in both SB groups compared to control. On d-21, areas of thymus medulla and spleen germinal centers were noted higher (p<0.05) in SB-1 group. The villus height and villus surface area increased (p<0.05) in duodenum and jejunum in both SB groups on d-21, and in SB-1 on d-35, respectively compared to ZnB and control. On d-21, number of goblet cells containing mucins of acidic nature increased (p<0.05) in all the segments of small intestines in SB-1 group compared to control, and on d-35 in ileum compared to other groups. Conclusion In conclusion, SB improved growth performance and immunity as well as modulated morphology of lymphoid organs and gut mucosa in broiler chickens

Clinical and electrophysiological efficacy of leaf extract of Gingko biloba L (Ginkgoaceae) in subjects with diabetic sensorimotor polyneuropathy

Purpose: To investigate the health benefits of Gingko biloba L. leave extract EGb 761 in patients with diabetic sensorimotor polyneuropathy (DSP).Method: In a randomized, double-blind, placebo trial, patients (n = 156) received Gingko biloba (120 mg/day) or placebo for 6 months. Efficacy of Gingko biloba extract EGb 761 was assessed on the reduction in the scores of “Short-Form McGill Pain Questionnaire” (SF-MPQ) and improvements in latency, amplitude and conduction velocity of four sensory (ulnar, median, peroneal and sural) and four motor (ulnar, median, peroneal and tibial) nerves.Results: Gingko biloba significantly improved the mean scores of sensory, affective, visual analogue score (VAS) and present pain intensity (PPI) of SF-MPQ on 3 and 6 month post-treatment. At the start of experiment in the Gingko biloba-treated group, scores for sensory, affective, VAS and PPI domains were 12.90 ± 7.21, 4.40 ± 1.79, 4.38 ± 1.69 and 3.24 ± 0.78 respectively. After 6-months treatment with Gingko biloba, scores for sensory, affective, VAS and PPI domains were reduced (p &lt; 0.01) to 7.24 ± 4.91, 3.11 ± 1.81, 3.37 ± 1.35 and 2.45 ± 0.65 respectively. Contrarily, in the placebo-administered group, sensory domain was (p &lt; 0.01) deteriorated after 6 month (4.70 ± 1.87) compared to the baseline (4.04 ± 1.67). Gingko biloba extract EGb 761 failed to influence the electrophysiological measures when compared with the placebo group. The common adverse effects observed with Gingko biloba were somnolence and dryness of mouth compared with the placebo-treated patientsConclusion: Gingko biloba extract EGb 761 seems to be an effective and safe drug for reducing symptoms of DSP without any apparent effect on the electrophysiological attributes of sensorimotor nerves.Keywords: Diabetic polyneuropathy, Diabetes mellitus, Electrophysiological parameters, Gingko biloba, Sensorimotor nerves, Short-Form McGill Pain Questionnair

Professional Identity of Pakistani Veterinary Students: Conceptualization and Negotiation

Most work on the professional identity of veterinary and medical professionals has been conceptualized in the US and Europe. It reports professional identity formation to be highly individualized, triggered by experiences of identity distress, and identity negotiation strategies to be generally focused around personal reflection. However, within Asia, important sociocultural differences exist that might influence professional identity and its development. Societal values may take precedence over individual ones, and some cultures consider the veterinary profession as stigmatized. With this background, we seek to understand professional identity and its construction in Pakistani veterinary students. We selected five students through purposive sampling and invited them for narrative interviews. Social identity theory and Maslow’s theory of hierarchy of needs predominantly contributed to the theoretical framework, which together with principles of social phenomenology and narrative analysis informed qualitative analysis of the transcribed interviews using an in-depth approach. We found that students’ professional identity was predominantly socially constructed, though their sense of their identity was not very well developed. Role models, social stigma, professional socialization in clinical settings, gender, and to some extent, cultural interpretations of religious messages seemed to mediate professional identity development. Students responded differently to their understanding of professional stigma, making sense of stigma through strategies such as denial or internalization. Since Pakistani veterinary students experience social and personal values differently compared with those from predominantly individualistic cultures, identity formation through reflecting on personal values may be less effective than strategies that emphasize social learning and beliefs. &lt;/jats:p&gt

Quantitative differences in activities of back and pelvic limb muscles during walking and trotting between chronically lame and nonlame horses

Objective—To assess differences in activities of back and pelvic limb muscles by use of surface electromyography (SEMG) in chronically lame and nonlame horses during walking and trotting.&lt;jats:p/&gt;Animals—12 nonlame horses and 12 horses with unilateral chronic mild to moderate pelvic limb lameness.&lt;jats:p/&gt;Procedures—On each horse, bipolar electrodes were attached to the skin over the midpoints of the right and left longissimus thoracis (Lot), semitendinosus (Set), biceps femoris (Bif), gluteus medius (Glm), and extensor digitorum longus (Edl) muscles. For each muscle, synchronous kinematic and SEMG recordings were made during walking and trotting on a treadmill; mean, maximum, and minimum muscle activities and maximum-to-mean and minimum-to-mean activity ratios were determined. For each lame or nonlame horse, data from both pelvic limbs were averaged; in lame horses, data from the nonlame and lame pelvic limbs were also examined separately (NL-L and L-L values, respectively). Comparisons were made among the 4 data sets and between gaits.&lt;jats:p/&gt;Results—During walking, the NL-L maximum-to-mean ratios for Bif and Glm muscles were significantly greater and in lame horses, L-L and NL-L minimum-to-mean ratios for Set, Bif, Glm, and Lot muscles were significantly less than those for nonlame horses. During trotting, minimum-to-mean ratios for Set, Glm, and Lot muscles in lame horses were significantly lower than those for nonlame horses. Activity of the Edl muscle was not affected by lameness.&lt;jats:p/&gt;Conclusions and Clinical Relevance—In lame horses, variation in muscle use was detectable via SEMG. In chronically lame horses, back and pelvic limb muscle activities were affected differently during walking and trotting

Pattern of varicocele vein blood gases in patients undergoing microsurgical Varicocelectomy

Abstract Background Varicocele is known to be associated with infertility and sperm disorders. The exact cause of this ailment is not fully understood. There are limited numbers of studies where venous blood gases (VBGs) of varicocele veins were determined with conflicting results. Therefore, we have investigated the pattern of VBGs in both internal spermatic and external spermatic varicocele veins and correlation with semen quality parameters in infertile individuals who underwent left microsurgical varicocelectomy. Methods Patients (n = 27) undergoing left microsurgical varicocelectomy at a tertiary care hospital, were included in the study. Before surgery, semen parameters and scrotal color Doppler ultrasonography was performed. During surgery, blood sample was drawn from varicocele veins (internal spermatic and external spermatic veins) and a peripheral arm vein of the same patient as a control. The VBGs of all veins under study were estimated and compared with each other. The VBGs were also correlated with various semen quality parameters. Data, expressed as Mean ± SD, regarding VBGs in three veins were analyzed using one-way ANOVA. The correlation between VBGs and semen quality parameters was determined using Pearson’s correlation. Differences were considered significant at p < 0.05. Results The pH was found to be higher (p < 0.01) in the internal spermatic vein compared with the external spermatic and the peripheral veins. Partial pressure of oxygen (pO2) and oxygen saturation (sO2) were higher (p < 0.01) in the internal spermatic vein compared with the peripheral vein. However, concentration of bicarbonate (HCO3) was lower (p < 0.01) in both veins compared with the peripheral vein. Partial pressure of carbon dioxide (pCO2) was also lower (p < 0.01) in the varicocele veins compared with the control vein. Conclusion The internal spermatic veins had higher pH and oxygen tension, but lower HCO3 and pCO2 levels compared with the control peripheral veins. External spermatic veins had lower pCO2 and HCO3 but other VBGs were similar to the peripheral veins. The shift of VBGs of internal spermatic vein toward arterial blood pattern may be a missing link to understand the pathophysiology of varicocele

Efficacy of Whole-Blood Del Nido Cardioplegia Compared with Diluted Del Nido Cardioplegia in Coronary Artery Bypass Grafting: A Retrospective Monocentric Analysis of Pakistan

Background and Objectives: Cardioplegia is one of the most significant components used to protect the myocardium during cardiac surgery. There is a paucity of evidence regarding the utilization of whole-blood Del Nido cardioplegia (WB-DNC) on clinical outcomes in coronary artery bypass grafting (CABG). The purpose of this retrospective cross-sectional study is to compare the effectiveness of diluted (blood to crystalloid; 1:4) Del Nido cardioplegia (DNC) with WB-DNC in patients who underwent elective CABG in a tertiary care hospital in Lahore-Pakistan. Materials and Methods: This was a retrospective descriptive study conducted at the Department of Cardiovascular Surgery, King Edward Medical University, Lahore. The medical database of all consecutive patients admitted from January 2018 to March 2020 and who fulfilled the inclusion criteria were reviewed. Results: Out of 471 patients admitted during the study period, 450 underwent various elective cardiac surgeries. Out of 450, 321 patients (71.33%) were operated on for CABG. Only 234/321 (72.89%) CABG patients fulfilled our inclusion criteria; 120 (51.28%) patients received WB-DNC, while 114 (48.71%) patients were administered with DNC. The former group presented with better clinical outcomes compared with the latter in terms of lesser requirements of inotropic support, low degree of hemodilution, shorter in-hospital stay, improved renal function, and cost-effectiveness. Peak values of serum Troponin-T (Trop-T), creatine kinase-myocardial band (CK-MB) release, and activated clotting time (ACT) were also lower in the WB-DNC group compared with the DNC group. Conclusions: The WB-DNC conferred better myocardial protection, improved early clinical outcomes, and also proved to be economical for patients undergoing elective CABG compared with classical crystalloid cardioplegia solution

Morphological Modulation of Broiler Organs in Response to an Organic Acid–Phytogen Composite in Healthy Broilers

In this study, we investigated broiler growth traits, intestinal health and immune aggregates in response to supplementation of Origanum vulgare and Cinnamomum verum, citric acid and malic acid in drinking water at varying levels and durations on broiler. We randomly allocated 140 day-old broilers into four (4) groups, with each group having seven replicates (n = 5). A basal diet and water were provided to all the groups ad libitum in accordance with standard farming practices. Keeping group I as the control, group II was supplemented with 1 mL/3.3 L of water for 1–4 days, 1 mL/4 L from 15–18 days and 1 mL/4 L water from 26–29 days. Group III and IV were supplemented with 1 mL/4 L of water and 1 mL/6 L of water for 35 days, respectively. After the completion of the trial (day 35), two broilers per replicate (14 birds per group) were slaughtered to sample the visceral organs. The results demonstrated that the feed conversion ratio (FCR) and body weight gain improved (p ≤ 0.05) during the fourth and fifth week of the trial in group III in comparison to the control group. Although the small intestine villus height and villus-height-to-crypt-depth ratio improved (p ≤ 0.05) in group III, the muscularis externa thickness of the ileum was highest (p ≤ 0.05) in the control group. Similarly, the lymphatic follicular and nodular area of the immune organs improved (p ≤ 0.05) in group III. In all segments of the small intestine (duodenal, jejunal and ileal), the number of acidic and total goblet cells was highest (p ≤ 0.05) in group II. In conclusion, dietary Origanum vulgare, Cinnamomum verum, citric acid and malic acid at the dose of 1 mL/4 L of drinking water (group III) was the most effective in improving the growth performance, gut development and associated immune components in broilers
