Abstract
Sipuleucel-T (sip-T) is the only FDA-approved autologous cellular immunotherapy for metastatic castration-resistant prostate cancer (mCRPC). To elucidate parameters of the response profile to this therapy, we report high-dimensional analyses of sip-T using cytometry by time of flight (CyTOF) and show a lymphoid predominance, with CD3+ T cells constituting the highest proportion (median ∼60%) of sip-T, followed by B cells, and natural killer (NK) and NKT cells. We hypothesized that treatment of sip-T with homeostatic cytokines known to activate/expand effector lymphocytes could augment efficacy against prostate tumors. Of the cytokines tested, IL15 was the most effective at enhancing activation and proliferation of effector lymphocytes, as well as augmenting tumor cytotoxicity in vitro. Co-culture of sip-T with IL15 and control or prostate-relevant antigens showed substantial activation and expansion of CD8+ T cells and NKT cells in an antigen-specific manner. Adoptive transfer of IL15-treated sip-T into NSG mice resulted in more potent prostate tumor growth inhibition compared with control sip-T. Evaluation of tumor-infiltrating lymphocytes revealed a 2- to 14-fold higher influx of sip-T and a significant increase in IFNγ producing CD8+ T cells and NKT cells within the tumor microenvironment in the IL15 group. In conclusion, we put forward evidence that IL15 treatment can enhance the functional antitumor immunity of sip-T, providing rationale for combining IL15 or IL15 agonists with sip-T to treat patients with mCRPC.

Abstract
BACKGROUND AND AIMS There is limited information on the clinical significance of complete right bundle branch block (CRBBB) in young individuals. The aim of this study was to determine the prevalence and significance of CRBBB in a large cohort of young individuals aged 14-35 years old. METHODS From 2008 to 2018, 104,369 consecutive individuals underwent a cardiovascular assessment with a health questionnaire, electrocardiogram, clinical consultation, and selective echocardiography. Follow-up was obtained via direct telephone consultations. Mean follow-up was 7.3 ± 2.7 years. RESULTS CRBBB was identified in 154 (0.1%) individuals and was more prevalent in males compared with females (0.20% vs. 0.06%; p<0.05) and in athletes compared with non-athletes (0.25% vs. 0.14%; p<0.05). CRBBB-related cardiac conditions were identified in 7 (5%) individuals (4 with atrial septal defect, 1 with Brugada syndrome, 1 with progressive cardiac conduction disease and 1 with atrial fibrillation). Pathology was more frequently identified in individuals with non-isolated CRBBB compared with individuals with isolated CRBBB (14% vs 1%; p < 0.05) and in individuals with a QRS duration of ≥130 milliseconds (ms) compared with individuals with a QRS of <130ms (10% vs 1%; p<0.05). CONCLUSION The prevalence of CRBBB in young individuals was 0.1% and was more prevalent in males and athletes. CRBBB-related conditions were identified in 5% of individuals and were more common in individuals with non-isolated CRBBB and more pronounced intraventricular conduction delay (QRS duration of ≥130ms). Secondary evaluation should be considered for young individuals with CRBBB with symptoms, concerning family history, additional electrocardiographic anomalies or significant QRS prolongation (≥130ms).

Abstract
Lipophagy is a selective degradation of lipids by a lysosomal-mediated pathway, and dysregulation of lipophagy is linked with the pathological hallmark of many liver diseases. Downregulation of lipophagy in liver cells results in abnormal accumulation of LDs (Lipid droplets) in hepatocytes which is a characteristic feature of several liver pathologies such as nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). Contrarily, upregulation of lipophagy in activated hepatic stellate cells (HSCs) is associated with hepatic fibrosis and cirrhosis. Lipid metabolism reprogramming in violent cancer cells contributes to the progression of liver cancer. In this review, we have summarized the recent studies focusing on various components of the lipophagic machinery that can be modulated for their potential role as therapeutic agents against a wide range of liver diseases.

Abstract
Extracellular vesicles (EVs) are membrane-derived messengers which have been playing an important role in the inflammation and pathogenesis of lung diseases. EVs contain varieties of DNA, RNA, and membrane receptors through which they work as a delivery system for bioactive molecules as well as intracellular communicators. EV signaling mediates tumor progression and metastasis. EVs are linked with many diseases and perform a diagnostic role in lung injury and inflammation so are used to diagnose the severity of diseases. EVs containing a variety of biomolecules communicate with the recipient cells during pathophysiological mechanisms thereby acquiring the attention of clinicians toward the diagnostic and therapeutic potential of EVs in different lung diseases. In this review, we summarize the role of EVs in inflammation with an emphasis on their potential as a novel candidate in the diagnostics and therapeutics of chronic obstructive pulmonary disease, asthma, and sarcoidosis.

Abstract
BACKGROUND The current study was designed to highlight the effects of heterologous platelet-rich plasma (PRP) on deteriorated hepatic tissues and impaired glucose metabolism of alloxan-induced diabetic mice. METHODS 30 male mice were divided into a control (CG), PRP (PG), diabetic (DG), and two treated groups (T1G and T2G). PG was given PRP treatment (0.5 ml/kg body weight) twice a week for four weeks. DG, T1G and T2G were given alloxan (150 mg/kg) to induce diabetes. After confirmation, PRP treatment was given to T1G and T2G for two and four weeks respectively while DG was left untreated. Upon completion of the said experimental period, liver samples were taken for histological and gene expression analyses. RESULTS The study found that the liver tissue of the DG group showed signs of damage, including hepatocyte ballooning, sinusoid dilatation, and collagen deposition. However, these changes were significantly reduced in both T1G and T2G groups. The expression of several genes related to liver function was also affected, with upregulation of Fbp1 and Pklr, and downregulation of Pck1 in the DG group. PRP treatment restored Fbp1 expression and also increased the expression of glycolytic pathway genes Hk1 and Gck, as well as Wnt signalling pathway genes Wnt2, Wnt4, and Wnt9a in both treated groups. CONCLUSION Current study revealed that heterologous PRP may partly alleviate high glucose levels in diabetics possibly by mediating glucose metabolism via inhibition of Wnt signalling pathway.

Abstract
Natural killer (NK) cells are considered to be the foremost fighters of our innate immune system against foreign invaders and thus tend to promptly latch onto the virus-infected and tumor/cancerous cells, killing them through phagocytosis. At present, the application of genetically engineered Chimeric antigen receptor (CAR) receptors ensures a guaranteed optimistic response with NK cells and would not allow the affected cells to dodge or escape unchecked. Hence the specificity and uniqueness of CAR-NK cells over CAR-T therapy make them a better immunotherapeutic choice to reduce the load of trafficking of numerous tumor cells near the healthy cell populations in a more intact way than offered by CAR-T immunotherapy. Our review mainly focuses on the preclinical, clinical, and recent advances in clinical research trials and further strategies to achieve an augmented and efficient cure against solid tumors.

Abstract
Therapeutic cancer vaccines including sipuleucel- T , a prostatic acid phosphatase (PAP) targeted vaccine that improves survival in metastatic castration-resistant prostate cancer (mCRPC), can produce immune responses that translate to clinical benefit. The effects of sequential checkpoint inhibitors after therapeutic vaccine on immune responses are unknown. Avelumab is an anti-programmed death ligand-1 monoclonal antibody evaluated in patients with mCRPC in the JAVELIN solid tumor phase 1 trial expansion cohort, enriched for patients with a previous therapeutic prostate cancer-targeted vaccine. mCRPC patients received intravenous avelumab 10 mg/kg every 2 weeks with imaging every 6 weeks. Peripheral blood T-cell responses to PAP and to PA2024, the peptide containing PAP utilized by the vaccine, were evaluated pre and posttreatment. Eighteen patients enrolled, and previous treatments included abiraterone or enzalutamide in 14 (78%), therapeutic cancer vaccine in 14 (78%), and chemotherapy in 4 (22%). Avelumab had a manageable safety profile. There were no sustained prostate specific antigen decreases. Of 17 patients evaluable for best overall response by RECISTv1.1, 12 had stable disease (SD) and 5 had progressive disease. Seven patients had SD for >24 weeks posttreatment. Fourteen patients had previously received therapeutic cancer vaccines. Eleven (79%) had SD as the best overall response. Of these 14 patients, 9 had previously received sipuleucel T . Analysis of antigen-specific T-cell responses pre and postavelumab treatment did not demonstrate changes in interferon-γ production or proliferation in response to PAP or PA2024. This unplanned analysis does not support the use of sequential therapeutic cancer vaccine therapy followed by programmed death ligand-1 inhibition in mCRPC.

Abstract
A high-fat diet (HFD) is one of the most prominent causative factors for obesity and metabolic inflammation. The effects of HFD overconsumption on intestinal histology, expression of haem oxygenase-1 (HO-1), and transferrin receptor-2 (TFR2) remain elusive. The present study was conducted to analyze the effect of HFD on these parameters. To develop the HFD-induced obese model, rat colonies were divided into 3 groups; the control group was reared on normal rat chow, whereas groups I and II were given HFD for 16 weeks. Hematoxylin and eosin (H & E) staining revealed marked epithelial changes, inflammatory cell infiltrates, and destruction of mucosal architecture in both experimental groups as compared to the control group. Sudan Black B staining showed a high triglyceride deposition in the intestinal mucosa of animals fed on HFD. Atomic absorption spectroscopy revealed a decrease in tissue copper (Cu) and selenium (Se) concentration in both HFD experimental groups. Whereas the cobalt (Co) and manganese (Mn) levels were comparable to controls. The mRNA expression levels of HO-1 and TFR2 were found to be significantly upregulated in HFD groups compared to the control group. Hence, HFD consumption leads to histopathological changes and altered gene expression in the rodent intestine. So, one should remove HFD from daily meals to avoid related metabolic complications.

Idiopathic generalized epilepsy (IGE) is the most prevalent type of epilepsy with genetic origin. Mutations in ion channel genes have been identified as a common cause of IGE. Several studies have reported various epilepsy risk variants of GABRG2 (gamma-aminobutyric acid type A receptor subunit gamma2 subunit) gene in different ethnic groups, but the results are inconsistent. The purpose of this case-control research is to determine if GABRG2 polymorphisms contribute to IGE susceptibility and antiepileptic drug resistance in Pakistani population. For this purpose, we genotyped exon2, exon5 (C540T and C588T), exon7 (T813C), exon8 (K289M), and exon9 of GABRG2 gene by restriction fragment length polymorphism and Sanger's sequencing in 87 drug-responsive idiopathic generalized epilepsy patients, 55 drug-resistant epilepsy patients, and 83 healthy controls. Restriction fragment length polymorphism (RFLP) and sequencing results indicated only C588T polymorphism in the studied subjects. The comparison of genotypic and allelic frequencies showed significant differences between IGE patients and control groups (P = 0.008 and odds ratio = 4.2) and nonsignificant association of C588T polymorphism in antiseizure medication-resistant patients (P = 0.9). Our findings showed that C588T polymorphism of GABRG2 is a risk variant for IGE in Pakistani population. Further studies are required to validate the results.

Abstract
Bisphenol S (BPS), an analog of bisphenol A (BPA), has been frequently detected in consumer products, food wrappers, plastics, and thermal papers. Since the liver is a hub of metabolic and detoxification pathways, thus intimately related to BPS presence in the environment and body. The current study was designed to investigate the effects of BPS administration in an animal model. Twenty-five male Wistar rats weighing 175 ± 25 g were randomly divided into control and treated groups. The control group was further divided into group I (no treatment) and group II (corn oil), whereas the treatment group was divided into D-I (40 mg/kg/day), D-II (200 mg/kg/day), and D-III (400 mg/kg/day) groups, getting oral doses of BPS for 15 days. Data analysis showed a significant statistical increase in hepatic enzymes ALT (33.4%), AST (25.4%), and ALP (529.6%) in the D-III group along with the development of hypercholesterolemia and hypertriglyceridemia in all BPS groups. Aberrant mRNA expressions of some key hepatic iron regulatory genes and inflammatory mediators were evident through qRT-PCR. Bisphenol S caused congestion of central vein from mild to moderate in hepatic sections. In conclusion, our investigation insinuates BPS intoxication potential and therefore may not be a safe alternative to BPA.

Abstract
Hepatocellular carcinoma (HCC), a leading cause of cancer related deaths is predominantly driven by chronic inflammatory responses. Due to asymptomatic nature and lack of early patient biopsies, precise involvement of inflammation in hepatic injury initiation remains unidentified. Aim of the study was to elucidate the regulation patterns of inflammatory signalling from initiation of hepatic injury to development of HCC. HCC mice model was established using DEN followed by repeated doses of CCl4 and sacrificed at three different stages of disease comprising 7, 14 and 21 weeks. Serum biochemical tests, hepatic lipids quantification, histopathology and qPCR analyses were conducted to characterize the initiation and progression of liver injury and inflammatory signalling. Notably, at 7 weeks, we observed hepatocyte damage and periportal necrotic bodies coupled with induction of Socs2/Socs3 and anti-inflammatory cytokine Il-10. At 14 weeks, mice liver showed advancement of liver injury with micro-vesicular steatosis and moderate collagen deposition around portal zone. With progression of injury, the expression of Socs3 was declined with further reduction of Il-10 and Tgf-β indicating the disturbance of anti-inflammatory mechanism. In contrast, pro-inflammatory cytokines Il1-β, Il6 and Tnf-α were upregulated contributing inflammation. Subsequently, at 21 weeks severe liver damage was estimated as characterized by macro-vesicular steatosis, perisinusoidal collagen bridging, immune cell recruitment and significant upregulation of Col-1α and α-Sma. In parallel, there was significant upregulation of pro/anti-inflammatory cytokines highlighting the commencement of chronic inflammation. Findings of the study suggest that differential regulation of cytokine suppressors and inflammatory cytokines might play role in the initiation and progression of hepatic injury leading towards HCC.

Abstract
BACKGROUND In recent years, nonalcoholic fatty liver disease (NAFLD) has reached epidemic proportions. Characteristic findings in NAFLD patients are elevated iron stores, as iron plays an important role in the pathophysiology of chronic liver disease. The current study was aimed at investigating the possible protective effects of N. sativa seeds and P. ovata husks on the regulation of iron homeostasis in NAFLD. METHODS Two age groups of Wistar rats (four weeks and twelve weeks old), further subdivided into four groups were fed on high fat/high sucrose (HF/SF) diet for sixteen weeks to induce NAFLD and randomized into three groups (HF/SF diet control (Group I), HF/SF diet with N. sativa seeds (Group II) and HF/SF diet with P. ovata husks (Group III) and normal diet, serving as negative control (Group 0). At the end of the experiment, histochemical analysis of hepatic sections, biochemical evaluates of the blood, and gene expression analysis were conducted. RESULTS The results revealed that both N. sativa seeds and P. ovata husks possess the capacity to maintain iron homeostasis by regulating the level of blood hemoglobin, serum iron contents, expression of key genes involved in iron metabolism, and iron deposition in hepatic sections. While N. sativa seeds proved more effective. CONCLUSIONS N. sativa seeds are a more potent iron regulator compared to P. ovata husks at reducing the iron overburden associated with NAFLD.

Abstract
The Hedgehog (Hh) pathway has emerged as a potential target for effectual hepatic repair based on convincing clinical and preclinical evidence that proves its significance in regulating hepatic damage. The purpose of this study is to probe the effect of quercetin on liver fibrosis through the modulation of the Hh pathway. Healthy male Wistar rats were divided into four groups (n = 10). The control group was treated with saline, rats in the remaining three groups received twice a week intoxication with intraperitoneal injections of thioacetamide (200 mg/kg) for the induction of hepatic fibrosis for 6 weeks. After 28 days of quercetin and silymarin treatment, histological changes, serum biochemical index, antioxidant enzyme activity, key mediators of Hh pathway and inflammation were analyzed. Serological analysis showed statistically improved cholesterol, H.D.L-Cholesterol, and L.D.L-Cholesterol in the treatment groups. Superoxide dismutase and glutathione levels were found to be increased after the treatment with quercetin and silymarin. mRNA expression of important mediators of the Hh signaling, and inflammation including Shh, Ihh, Ptch-1, Smo, Hhip, Gli-3, TNF-α, NFκ-β, and Socs-3 were significantly downregulated after the use of quercetin and silymarin. Quercetin also minimized the thioacetamide-induced histopathological changes, as confirmed by a lower degree of hepatic lobule degeneration, the intralobular occurrence of inflammatory cells, and a lower degree of hepatocytic necrosis. Sudan Black B staining showed remarked lipids improvements in the treatment groups. Taken together, these findings demonstrate that quercetin could ameliorate hepatic fibrosis by antagonizing the hedgehog pathway and also suggest the hedgehog pathway as a potential therapeutic target for the treatment of liver fibrosis.

Abstract
Autophagy is an evolutionary conserved catabolic process that plays physiological and pathological roles in a cell. Its effect on cellular metabolism, the proteome, and the number and quality of organelles, diversely holds the potential to alter cellular functions. It acts paradoxically in cancer as a tumor inhibitor as well as a tumor promoter. In the early stage of tumorigenesis, it prevents tumor initiation by the so-called "quality control mechanism" and suppresses cancer progression. For late-staged tumors that are exposed to stress, it acts as a vibrant process of degradation and recycling that promotes cancer by facilitating metastasis. Despite this dichotomy, the crucial role of autophagy is evident in cancer, and associated with mammalian targets of rapamycin (mTOR), p53, and Ras-derived major cancer networks. Irrespective of the controversy regarding autophagic manipulation, promotion and suppression of autophagy act as potential therapeutic targets in cancer treatment and may provide various anticancer therapies.

Abstract
Background Citrullinated proteins formed by peptidyl arginine deiminases (PADIs) deimination of arginine residues in proteins are of particular interest in arthritis pathogenesis. Polymorphisms on the PADI-4 gene lead to the malfunctioning of PADIs leading to the onset of arthritis. Objective The present study was conducted to determine the polymorphisms on the PADI-4 gene and their association with rheumatoid arthritis (RA) as well as Osteoarthritis (OA). Methodology To achieve the above-mentioned objective a case-control study was conducted. Blood samples were collected from RA, OA, and control subjects. DNA was extracted from each blood sample by modified organic method and was quantified as well as qualified by DNA gel electrophoresis and Nanodrop. Patients were tested for rs874881, rs11203366, rs11203367, rs2240336, rs2240337, rs2240339, rs1748033 and rs2240340 polymorphic sites by amplifying targeted regions through PCR with site-specific primers. Genotyping was performed by Restriction Fragment Length Polymorphism and direct sequencing method. Mutations were identified by analyzing sequences on BioEdit software. Allelic, genetic, and multiple site analysis were performed by SHEsis and PLINK software. Change in the amino acid sequence was identified by MEGA 6.0 software. Results Polymorphisms were identified on all targeted polymorphic sites except rs2240337 in both RA and OA individuals. In addition, two novel mutations were also identified in exon 4 identified i-e SCV000804840: c.218T > C and SCV000807675: c.241G > T. All the SNPs except rs11203366 were found to be significantly associated with RA at an allelic level whereas all SNP’s have been significant risk factors in the onset of OA. At genotypic level rs874881, rs11203366, rs2240339, SCV000804840 and SCV000807675 were significantly associated to RA development whereas rs874881, rs11203366, rs11203367, rs2240339, SCV000804840 and SCV000807675 were genetic risk factors in OA onset. Haplotype analysis indicated that GACCACGCC and GACCACGCT were highly significant in disease development. Polymorphisms identified altered the functioning of PADIs by altering their amino acid sequence. Conclusion In conclusion, it was found that PADI-4 gene polymorphism was not only involved in the onset of RA but was also found to be a significant risk factor in OA onset.

Abstract
Long noncoding RNAs (lncRNAs) are longer than 200 nucleotides in length and undergo splicing, capping, polyadenylation, and editing just like mRNA. Evidence is growing that they regulate transcription, splicing, RNA degradation, and translation of genes and that their expression has been linked to a variety of illnesses, including cancer. The advancement of next-generation and high-throughput sequencing has changed the way lncRNAs are identified and characterized, revealing a relationship between lncRNAs and several tumor types. Since then, they have gained a significant attraction as a promising candidate in cancer diagnosis, prognosis, and therapy. Furthermore, they are a good candidate for consideration as tumor biomarkers due to their high stability, better tissue/cell selectivity, aberrant expression in certain malignancies, and easy and noninvasive detection. In addition, lncRNAs are being examined as therapeutic targets in clinical trials for a variety of malignancies. This review highlights the potential of lncRNAs as biomarkers or therapeutic targets in light of the current progress, clinical investigations, and patents filed so far.

Abstract
BACKGROUND Disproportionate fatty diet intake provokes hepatic lipid accumulation that causes non-alcoholic fatty liver disease, triggering the embryonically conserved Hedgehog (Hh) pathway in the adult liver. The present study incorporates exploring the impact of chronically administered unsaturated (D-1) and saturated (D-2) fat-enriched diets on hematological parameters, liver functioning, and lipid profile in the rat model. Besides, hepatohistology and real time gene expression analysis of Hh signaling pathway genes i.e., Shh, Ihh, Hhip, Ptch1, Smo, Gli1, Gli2, and Gli3 were carried out. METHODS AND RESULTS Fifteen Rattus norvegicus (♂) of 200 ± 25 g weight were grouped into control, D-1, and D-2. Animals were fed on their respective diets for 16 weeks. Fatty diet intake resulted in neutropenia, lymphocytosis, monocytosis, polycythemia, and macrocytosis in both experimental groups. Altered liver injury biomarkers, hypertriglyceridemia, and significantly increased very-low-density lipoprotein VLDL were also noted in both high-fat diet (HFD) groups as compared to control. Hepatohistological examination showed disrupted microarchitecture, infiltration of inflammatory cells, cellular necrosis, widened sinusoidal spaces, and microvesicular steatotic hepatocytes in D-1 and D-2. Collagen deposition in both HFD groups marks the extent of fibrosis. Significant upregulation of hedgehog pathway genes was found in fatty diet groups. In comparison with the control group, Shh Ihh, Hhip, Ptch1, Smo, Gli1, Gli2, and Gli3 were upregulated in D-1. In D-2 Shh, Hhip, and Smo expressions were upregulated, Ihh exhibited downregulation as compared to control. CONCLUSION Excess fat deposits in liver due to chronic consumption of high-fat diet results in anomalous architecture and functioning. High-fat diet induced significant variations in Hh pathway genes expression; especially Shh, Ihh, Hhip, Ptch1, Smo, Gli1, Gli2, and Gli3 were upregulated. Infiltration of inflammatory cells ( ), widened sinusoidal spaces (▲), cellular necrosis, and micro vesicular steatotic hepatocytes (*) were shown in the liver. Significant collagen deposition in both HFD groups i.e. D-1 and D-2 confirmed liver fibrosis. Excessive intake of dietary fats impaired normal liver functioning and liver inflammation triggered Hh signaling in adult rats.

Abstract
Despite the best possible medication and treatment protocols, one-third of epilepsy patients have drug resistance which is associated with an elevated risk of mortality and debilitating psychological consequences. P-glycogen encoded by ABCB1 is major drug transporter for a wide variety of AED. To evaluate the complex haplotypic association, genetic and allelic frequency distribution of rs1128503, rs1045642, and rs2032582 polymorphisms of ABCB1 gene with drug resistance in Pakistani pediatric epilepsy patients, we performed this study. A total of 337 individuals including 100 healthy control, 110 drug-resistant patients, and 127 drug-responsive patients were enrolled and genotyped for three polymorphisms. PCR and direct sequencing of DNA were done for genotyping. All the studied SNPs showed a statistically significant association with drug-resistant epilepsy at p < 0.01. In addition, we identified a novel variant at c 0.2678C > A (SCV001712095) position. The haplotype analysis indicated strong linkage disequilibrium between three SNPs. The in-silico analysis indicated that rs2032582 polymorphism at c 0.2677T > A is benign while c 0.2677T > G and c 0.2678C > A are possibly damaging. Our findings showed that pharmacogenetic variants play a key role in disease. Our findings shed light on the pharmacogenomic association of ABCB1 with epilepsy which might facilitate study on pharmacokinetics concerning ethnology.

Abstract
BACKGROUND Migraine is a chronic neurovascular condition characterized by recurring attacks of pulsating headaches. Genome-wide association studies (GWAS) identified many potential loci associated with migraine. To check the association of polymorphisms of PRDM16 (rs2651899), LRP1 (rs11172113), and TRPM8 (rs10166942) with migraine, the first time a case-control study was conducted in understudied Pakistani population. METHODS The study included 127 migraine patients (21 in migraine with aura and 106 with migraine without aura group) and 120 healthy control subjects from different areas of Punjab, Pakistan. Blood samples were collected from all the participants, and DNA was isolated from the lymphocytes by the modified organic method. Sanger's sequencing was done for PRDM16 (rs2651899), LRP1 (rs11172113), and TRPM8 (rs10166942) in all the samples to check the genotype. Logistic regression analysis was done using SPSS 20.0 to check the association of these SNPs with migraine susceptibility. RESULTS We found statistically significant differences between case and control group for PRDM16 (rs2651899) at genotypic level (p < 0.001), allelic level (p < 0.001; OR 3.088; 95% CI 2.082-4.579) and for dominant model (p < 0.001; OR 5.437; 95% CI 3.112-9.498). The major findings of this study suggested that PRDM16 rs2651899 is strongly associated with migraine in overall and subgroup analysis of genotypes. LRP1 (rs11172113) showed significant association with migraine except in subgroup comparison. A similar trend of association was found for TRPM8 (rs10166942) however, significant association was found only at the allelic level but no significant difference was seen at the genotypic level between case and control. One novel mutation c.67 + 4436_67 + 4438delA was also identified in the current study near LRP1 (rs11172113) polymorphic site. CONCLUSION In this first-ever replication report from Pakistan, PRDM16 (rs2651899) was found as a potential genetic marker in migraine susceptibility while LRP1 (rs11172113) and TRPM8 (rs10166942) showed partial association in subgroup analysis.

Abstract
The Indian crested porcupine (Hystrix indica) is a vertebrate pest of agricultural lands and forest. The study was aimed to report the damage to local crops by the Indian crested porcupine (Hystrix indica) in the Muzaffarabad District. A survey was conducted to identify the porcupine-affected areas and assess the crop damage to the local farmers in district Muzaffarabad Azad Jammu and Kashmir (AJK) from May 2017 to October 2017. Around 19 villages were surveyed, and a sum of 191 semi-structured questionnaires was distributed among farmers. Crop damage was found highest in village Dhanni where a porcupine destroyed 175 Kg/Kanal of the crops. Regarding the total magnitude of crop loss, village Danna and Koomi kot were the most affected areas. More than half (51.8%) of the respondents in the study area suffered the economic loss within the range of 101-200$, and (29.8%) of the people suffered losses in the range of 201-300$ annually. Among all crops, maize (Zea mays) was found to be the most damaged crop ranging between 1-300 Kg annually. In the study area, porcupine also inflicted a lot of damages to some important vegetables, including spinach (Spinacia oleracea), potato (Solanum tuberosum) and onion (Allium cepa). It was estimated that, on average, 511Kg of vegetables are destroyed by porcupine every year in the agricultural land of Muzaffarabad. It was concluded that the Indian crested porcupine has a devastating effect on agriculture which is an important source of income and food for the local community. Developing an effective pest control strategy with the help of the local government and the Wildlife department could help the farmers to overcome this problem.

Abstract
Background Acute myeloid leukemia (AML) is a bone marrow malignancy having multiple molecular pathways driving its progress. In recent years, the main causes of AML considered all over the world are genetic variations in cancerous cells. The RUNX1 and FLT3 genes are necessary for the normal hematopoiesis and differentiation process of hematopoietic stem cells into mature blood cells, therefore they are the most common targets for point mutations resulting in AML. Methods We screened 32 CN-AML patients for FLT3-ITD (by Allele-specific PCR) and RUNX1 mutations (by Sanger sequencing). The FLT3 mRNA expression was assessed in all AML patients and its subgroups. Results Eight patients (25%) carried RUNX1 mutation (K83E) while three patients (9.37%) were found to have internal tandem duplications in FLT3 gene. The RUNX1 mutation data were correlated with clinical parameters and FLT3 gene expression profile. The RUNX1 mutations were observed to be significantly prevalent in older males. Moreover, RUNX1 and FLT3-mutated patients had lower complete remission rate, event-free survival rate, and lower overall survival rate than patients with wild-type RUNX1 and FLT3 gene. The RUNX1 and FLT3 mutant patients with up-regulated FLT3 gene expression showed even worse prognosis. Bradford Assay showed that protein concentration was down-regulated in RUNX1 and FLT3 mutants in comparison to RUNX1 and FLT3 wild-type groups. Conclusion This study constitutes the first report from Pakistan reporting significant molecular mutation analysis of RUNX1 and FLT3 genes including FLT3 expression evaluation with follow-up. This provides an insight that aforementioned mutations are markers of poor prognosis but the study with a large AML cohort will be useful to further investigate their role in disease biology of AML.

Abstract
Among racial subgroups, Black men have the highest prostate cancer–specific death rate, yet they also exhibit prolonged overall survival compared with White men when treated with standard therapies, including sipuleucel-T. Differential immune responses may play a role in these observations. We compared circulating immune markers from 54 men (18 Black and 36 White) with metastatic castrate-resistant prostate cancer who received sipuleucel-T and were enrolled on an immune monitoring registry. Markers included longitudinal serum cytokine concentrations, humoral responses, and cellular immunity from baseline until 52 weeks after sipuleucel-T administration. Black men had statistically significantly higher median concentrations of TH2-type (interleukin [IL]-4, IL-10, and IL-13) and inflammatory cytokines (IL-2, IL-12, and IL-6) compared with prostate-specific antigen-matched White men both at baseline and 52 weeks after sipuleucel-T (2-sided P < .05). No differences by race were seen in either the antigen-specific T-cell response or the humoral responses to the immunizing antigen PA2024 and select secondary antigens.

Abstract
Molecular based identification of bat fauna in Pakistan has been relatively less explored. The current study was therefore planned to report for the first time the molecular classification of insectivorous bats (Pipistrellus coromandra) based on mitochondrion gene (COI) from Punjab, Pakistan. Specimens were collected from five different locations followed by DNA extraction with subsequent gene amplification and sequencing. All samples in the study had shown close identity matches with species (Pipistrellus coromandra) from India and (Pipistrellus tenuis) from Vietnam with percentage identity score of 96.11 and 95.58 respectively except one sequence which only revealed 86.78% identity match on Basic Local Alignment Search Tool (BLAST) and could only be assigned to genus level Pipistrellus sp. The results indicated negligible intra-population genetic distance among collected samples whereas the comparison with species from other countries had shown high intraspecific (P. coromandra) and interspecific (P. tenuis) mean genetic distances. The current study hence successfully proved the efficiency of COI gene as a molecular marker for species identification and in analyzing the patterns of genetic variation with species from other countries.

Abstract
Tacrolimus (TAC) is the drug of choice in immunosuppressive therapy for organ transplantation; however, adverse effects are still a major concern. The current study aims to decipher the short-term exposure of TAC on rat hepatocytes in relation to activation of hedgehog (HH) signaling pathway. Time dependent study was conducted using primary rat hepatocytes treated with TAC (36 µM) for 6, 12, 24 and 48 h. Western blot analysis was performed using cell lysate in order to analyze the regulation of HH pathway proteins including HHIP, SMO, PTCH, IHH, SHH, and GLI transcription factors. The study revealed change in protein expression of HH signaling molecules with activation of HH pathway, due to downregulation of HHIP, and enrichment of HH ligands with activation of SMO and GLI transcription factors. It is therefore, concluded that short term TAC exposure leads to upregulation of HH pathway in liver, which may initially act to repair the liver damage but can worsen the condition in case of prolonged immunosuppressive therapy. This insight could lead to understand association of off target effects of immunosuppressive drugs and occurrence of other liver diseases in transplant patients when it comes to long term immunosuppressive therapy. These findings also illuminate a novel direction that use of HH inhibitor might provide a therapeutic strategy for immune suppression related liver disorders.

Abstract
Funding Acknowledgements
Type of funding sources: Other. Main funding source(s): Cardiac Risk in the Young
Background
Moderate intensity exercise training in older patients with hypertrophic cardiomyopathy (HCM) can improve functional capacity, without significant harm. However, younger patients are attracted to high intensity training (HIT) regimes. The SAFE-HCM study demonstrated that an individually tailored, HIT programme in young patients with HCM was feasible, and provided both health and psychological benefits, without an increase in the burden of arrhythmia.
Purpose
To assess whether observed benefits of a HIT programme in young patients with HCM are sustained at 6 months.
Methods
Eighty patients with HCM (45.7y+/-8.6) underwent baseline clinical and psychological assessment. Individuals were randomised to a 12-week HIT programme (n = 40) or usual care (n = 40). Baseline evaluation was repeated at 12 weeks (T12). Feasibility, safety, health and psychological benefits were assessed. At 12-weeks individuals were encouraged to continue with the frequency and intensity of physical activity (PA) achieved at the end of the cardiac rehabilitation programme. Participants in the exercise arm were invited to follow-up at 6 months (T6m).
Results
The majority (83%) of participants completed the 12-week study. At T12 there was no significant difference between groups in the composite arrhythmia safety outcome (p = 0.99). The indices of exercise capacity were significantly improved in the exercise compared to the control group; peak VO2 (+3.7ml/kg/min [CI 1.1,6.3], p = 0.006), VO2/kg at anaerobic threshold (VO2/kgAT) (+2.44ml/kg/min [CI 0.6,4.2], p = 0.009), time to AT (+115s [CI 54.3,175.9], p < 0.001) and exercise time (max ET) (+108s [CI 33.7,182.2], p = 0.005). The exercise group also demonstrated greater reduction in systolic BP (-7.3mmHg [CI -11.7,-2.8], p = 0.002), BMI (-0.8kg/m2 [CI-1.1,-0.4], p < 0.001), anxiety (-2.6 [CI-3.6,-1.6], p= <0.001) and depression (-1.1 [CI -2.0,-0.2], p = 0.015) scores. At T6m patient reported exercise adherence was comparable to baseline PA in 33/34 of the exercise group attending for follow up. Most exercise gains dissipated with the exception of time to AT (p = 0.002), max ET (p = 0.003), VO2/kgAT (p = 0.04) and anxiety score (p < 0.001) (Figure 1). There were no sustained episodes of atrial or ventricular arrhythmias. The incidence of NSVT did not differ between time points (p = 0.09).
Conclusion
A 12-week HIT programme in young patients with HCM offers considerable gains in fitness and psychological outcomes, with no increase in arrhythmic burden. At T6m exercise levels as well as most physiological adaptations and health benefits returned to baseline, as seen in other studies when formal participation in an exercise programme comes to an end. This highlights the importance of the implementation of strategies to encourage ongoing engagement in PA. Potential solutions include identification of barriers to exercise, as well as adoption of novel tele-rehabilation approaches.

Abstract
Abstract
Introduction
A service evaluation audit highlighted significant variation in our practice as regards catheterisation in NOF patients. A pilot protocol was developed with real time data monitoring to see if we could improve our patients’ pathway.
Method
The protocol focussed on early catheterisation, monitoring the condition of patients’ skin, documentation around catheter care and removal instructions and surveillance for urinary tract infection rates (UTI)
Results
150 patients were included in the pilot. There was a reduction by more than 50% of patients assessed as having at risk or broken skin. 94.5% of patients were catheterised out of theatres (previously only 4%) saving an average of 14 minutes of theatre time per case. Delays in catheter removal after documented request reduced by 2 days and our UTI rates were relatively unchanged (3.3% compared to 2.7%). Documentation significantly improved. We also noted that overall length of stay was reduced by 2 days.
Conclusions
Standardising our care pathway has improved our patient care and documentation. It has benefitted theatre efficiency and also nursing of fragile skin in 'at risk' patients. Prompting early removal and compliance may have also had a positive impact on overall length of stay. This has been a successful quality improvement project in our department.

Abstract
Introduction The COVID 19 pandemic has brought unprecedented challenges in healthcare, leading to a dramatic change in service provision and impacting surgical training. We developed a new educational timetable to maintain an ethos of education safely; focusing on providing an opportunity to develop non-technical skills and maintain reflective practice. Method Microsoft Teams was used in our department with two separate streams of weekly education; journal club with focus on developing critical evaluation skills, and a case based in depth discussion forum to develop presentation skills and evidence based management. A questionnaire was sent out after 10 weeks to evaluate the effectiveness and engagement. Results From 53 responses, 72% felt that their engagement in teaching increased with a virtual platform with an overall satisfaction of 88%. Reflective practice increased and 40% felt their non-technical skills improved. Overall, 68% preferred to continue learning virtually and 88% would recommend this to their peers. 92% felt that the platform played a pivotal role in helping maintain team morale during this period. Conclusions There has been good engagement with positive reflection and learning at a time of great change in the NHS benefiting training and non-training doctors. We recommend incorporating virtual platforms to provide education in all surgical departments.

Abstract
The present study investigated the (i) socio-demographic predictors of psychological distress, (ii) socio-demographic predictors of satisfaction from online classes, and (iii) the relationship between psychological distress and satisfaction from online classes among university students of Pakistan during the COVID-19 pandemic. An online questionnaire-based survey was conducted. A total of 2220 respondents that was enrolled at the University of the Punjab (PU), University of Management and Technology (UMT), and the University of Central Punjab (UCP) were involved in the current study. Data were collected at a 64% response rate and analyzed with SPSS IBM Version 21.0. Results revealed that approximately 41% of the students were facing severe psychological distress while about 65% were found unsatisfied with online classes. Besides, a linear negative relationship between the independent variable, i.e. psychological distress and the dependent variable, i.e. satisfaction from online classes was found. Therefore, to minimize the level of psychological distress and increase students' satisfaction with online classes it is highly recommended to take precautionary measures by the relevant stakeholders.

Abstract
Bisphenol A (BPA), an imperative environmental contaminant used in polycarbonate plastics. Due to limited information concerning the effect of BPA on lungs, this study design to assess whether BPA cause alterations in histopathology and trace metal content in lungs of rats. They were divided into five groups with five rats per group. Group I was named as control group. Group L6 and L12 were received BPA (10 mg/kg body weight/day) for 6 weeks and 12 weeks respectively. Group H6 and L12 were given BPA (25 mg/kg body weight/day) for 6 weeks and 12 weeks respectively. Considerable alteration in Cu, Zn and Fe was detected in experimental groups. BPA also caused significant increase in the expression of tumor necrosis factor α that mediate the pulmonary inflammatory response. Comparative study of resolved proteins i.e. 72 KDa (matrix metalloproteinase 2 fragment) and 109 KDa (nucleolin) on SDS-PAGE showed their altered expression in experimental groups. Histopathology of experimental groups revealed altered architecture of lungs. Special staining of BPA treated groups showed significant number of mast cells in alveoli and bronchioles. Prolonged administration of BPA causes deleterious aggravating lung damage even at extremely low dose, so the use of BPA should be prohibited in plastic synthesizing industries.

Abstract
Rheumatoid Arthritis (RA) is an autoimmune disorder where multiple cytokines including IL-17A and IL-17F produced by T helper cell 17 (Th17), contribute to its pathogenesis. By initiating inflammatory responses in joints Th17 act as pathogenic driver leading to bone and cartilage destruction in RA patients. Hence, the planned study was aimed to estimate IL-17 gene polymorphism association with RA susceptibility in Pakistani population. The present study included 100 subjects (50 RA patients and 50 healthy controls). Blood samples were taken and DNA was isolated for genotyping purpose. Chi square and Logistic regression analysis was performed to check the association of selected SNPs with RA. For rs2397084 and rs763780 polymorphism T allele acted as significant risk factor as compared to the reference C allele. TT vs. CC comparison in rs2397084 showed that T allele is a risk factor (OR 5.538; 95%Cl 1.757-17.458) in RA susceptibility. In case of rs763780 heterozygous CT (OR 10.80; 95% Cl 3.736-31.218) and homozygous mutant TT (OR 7.50; 95% Cl 2.360-23.831) genotypes proved to be a potential risk for RA patients. The significant differences in allelic and genotypic frequencies were observed for both SNPs. While for rs2275913 significantly varied frequency was observed only for dominant model of inheritance and non significant differences were seen at allelic level. Variation at all these three polymorphic sites substituted mutant amino acids leading to further functional changes in protein structure. Three polymorphic sites rs2275913, rs763780 and rs2397084 positioned on IL-17 gene were significantly strong factors in RA incidence among Pakistani population as they alter normal function of inflammatory cytokine IL-17.

Abstract
Abstract
Background
T1 mapping by cardiovascular magnetic resonance (CMR) is an accurate tool to assess myocardial extracellular space with wider clinical applications in the aetiological characterization of cardiomyopathies. The aims of the study were to explore a possible role of myocardial T1 mapping in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and in first-degree relatives at risk and to investigate the possible relationship between left ventricular (LV) involvement at CMR and ECG features.
Methods
Thirty patients with ARVC (47% males, mean age 42±22 years) and 59 first-degree relatives who did not fulfil ARVC diagnostic Task Force criteria, underwent full diagnostic work-up including CMR with native and post-contrast T1 mapping.
Results
The CMR was abnormal in 26 (86%) patients with ARVC. The RV was affected in isolation in 13 (43%) patients. Prior to T1 mapping assessment, 2 (7%) patients exhibited isolated LV involvement and 11 (36%) patients showed features of biventricular disease. Left ventricular involvement was manifested as detectable LV late gadolinium enhancement (LGE) in 12 out of 13 cases. According to pre-specified septal T1 mapping thresholds, 11 (37%) patients showed abnormally high native T1 values. Myocardial T1 mapping was higher than normal in 5 (17%) patients who would have been classified as exhibiting a normal LV by conventional imaging. The proportion of patients with abnormal T1 values was similar in patients with or without LGE. Myocardial T1 mapping was higher than normal in 22 (37%) of the 59 first-degree relatives.
Conclusions
Native and/or post contrast myocardial T1 values are raised in almost half of patients with ARVC and in a similar proportion of unaffected first-degree relatives. T1 mapping offers the potential for early detection of LV involvement in patients with ARVC and in first-degree relatives at risk.

Abstract
Abstract
Background
Contemporary studies in hypertrophic cardiomyopathy (HCM) suggest that moderate intensity exercise can improve cardiorespiratory fitness without raising significant safety concerns. Although low/moderate intensity exercise may be appropriate for older HCM patients, it is unlikely to attract younger, often asymptomatic patients, who wish to engage in higher intensity regimes.
Purpose
To assess the feasibility, safety and outcomes of an individually tailored, high intensity exercise programme in young patients with HCM.
Methods
In this RCT, 80 patients with HCM, aged 16–60 (mean 45.7, [SD8.6]) underwent baseline testing with ECG, echocardiography, blood testing, exercise testing, 48-hour ECG and psychological assessment. Individuals were randomised to a 12-week supervised exercise programme (HRR increased from 70–85%) (n=40) or usual activity (n=40). Baseline investigations were repeated at 12 weeks.
Feasibility was assessed by a) recruitment, adherence and retention rates; b) staffing ratios and logistics; c) acceptability of the intervention/educational materials. Safety was assessed as a composite of 1) cardiovascular death, 2) cardiac arrest, 3) device therapy, 4) exercise induced syncope, 5) sustained/non-sustained (NS) ventricular tachycardia (VT) or 6) sustained atrial arrhythmias. Secondary outcomes included health and psychological benefits.
Results
67 individuals (82.5%) completed the study. Reasons for refusal included travel, work and family commitments. The majority (64.7%) of exercising individuals progressed to 85%HRR. Resource requirements were similar to other programmes. All individuals felt supported, more confident to exercise, and found educational materials clear and informative.
There was no significant difference between groups for the composite safety outcome. One individual experienced exercise induced syncope due to ventricular standstill (exercise) and another sustained VT (control). Both required device implantation. There was no significant difference between groups in episodes of NSVT (p=0.573) or ectopic burden (p=0.729).
At 12 weeks, exercise group participants demonstrated greater activity levels (+1.1 hours [CI 0.2–2.1], p=0.024). The change in peak aerobic capacity (+255.2ml/min [CI 93.2–417.1], p=0.003), time to anaerobic threshold (AT) (+115s [CI 54.2–176.0], p<0.001), total exercise time (+108.1s [CI 33.1–183.0], p=0.005) and oxygen uptake at AT (+2.44ml/kg/min [CI 0.6–4.2], p=0.009) were all significantly greater in the exercise group. HADS anxiety (p<0.001) and depression (p=0.017) scores demonstrated the greatest reduction in the exercise group.
Conclusions
A high intensity exercise programme is feasible in young patients with HCM, with considerable gains in cardiorespiratory fitness and psychological outcomes. Importantly, arrhythmia burden was not increased in the exercise group. Further research is still required to assess the long-term safety of high intensity exercise in the HCM population.

Abstract
The current pandemic of coronavirus disease 2019 (COVID-19) that led to an unprecedented crisis with significant health, social, and economic repercussions presented more serious concerns for those living with some chronic conditions such as epilepsy. This study was aimed to find out impact of the COVID-19 pandemic on management of epilepsy. A cross-sectional study was conducted through telephone interviews, targeting 213 caregivers of pediatric patients with epilepsy, belonging to underserved areas of Faisalabad, Punjab, Pakistan. A simple questionnaire was designed to record the responses of participants relevant to the direct and indirect effects of COVID-19 pandemic and their knowledge about possible ways that can be accessed for the management of epilepsy during an ongoing pandemic. The current study, which holds 77% of the respondents from rural areas and 23% from urban settings, showed that partial measures of lockdown taken to stop or slow the spread of COVID-19 resulted in adverse economic and health outcomes in the said population including cancelation of follow-up visits, worsening of seizures, job loss, burden of antiepileptic drugs (AEDs) costs, and discontinuation of medicines. Furthermore, knowledge about alternative ways to access health facilities was found very poor among caregivers. Income sources of poor people disrupted by lockdown can lead to unintentional nonadherence to medication, which is a clear picture of inequitable distribution of resources. This study highlights the major issues faced by the caregivers during this ongoing pandemic of COVID-19.

Abstract
Hepatitis C virus (HCV) causes persistent infection and invades host's innate and adaptive immune systems. During the eradication of this pathogen, the components of immune system may cause bystander damage to host, which might be even worse than the viral pathogenesis. Thus, the therapy should not only eliminate primary virus infection but also improve the inflammatory immune responses. The breakthrough of interferon free direct acting antiviral (DAA) drugs has provided the opportunity to unravel the association of HCV with immune response. This study aimed to examine the expression level of C-X-C motif chemokine ligand 10 (CXCL10) in the Peripheral blood mononuclear cells (PBMCs) of HCV infected patients treated with DAAs + Ribavirin. In this study we analyzed the expression levels of CXCL10 mRNA in the 90 chronic HCV patients using quantitative PCR (qPCR) prior, after, and during therapy with sofosbuvir/ribavirin (SOF+RBV) and sofosbuvir/daclatasvir/ribavirin (SOF+DCV+RBV), and further, the results were analyzed relative to treatment response. Significantly elevated CXCL10 mRNA was seen in naive patients having higher viral load (P = 0.005) and those suffering from hepatocellular carcinoma (P = 0.006). HCV patients had remarkable decline in CXCL10 level after 4, 12, and 24 weeks of therapy with DAAs. An approximate one-fold decrease was observed in patients who attained sustained virological response compared to untreated patients (P < 0.0001). Comparing the 2 regimens, the reduction in peripheral CXCL10 expression was more pronounced in patients undergoing SOF+DCV+RBV therapy. The current study implicitly shows the role of CXCL10 as an indicator of disruption of host-virus equilibrium and consequent pathogenesis of HCV during successful antiviral therapy. Furthermore, the drop in CXCL10 level after HCV viral clearance might reflect the DAA-induced alleviation in the extrahepatic manifestation of this infection.

Abstract
Bisphenol A (BPA) is one of the widely used chemical as a plasticizer and regarded as endocrine disruptor because of its ability to derail body metabolic functions and adverse effect on the vital organs. The present work outlined the subchronic effect of low-dose BPA (10 mg/kg) on histology of spleen, level of hepatic trace metals, and hepatic protein profile of Wistar rats. To conduct the research work, animals were grouped into two categories (n = 5). Group 1 was labelled as the control group and group 2 was taken as an experimental group. Experimental group was exposed to low-dose BPA for 12 weeks. Histopathology of spleen highlighted dilation in splenic sinuses, follicle activation, followed by depopulation in the area of white pulp and red pulp in the experimental group. Iron staining revealed significant hemosiderosis in the experimental group when compared with the control group. Statistically significant decrease was noted in zinc and copper concentrations, while nonsignificant change was observed for magnesium concentration through atomic absorption spectroscopy. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis was run for hepatic protein profiling, and as compared to control, elevated levels of different proteins were observed in the experimental group. It can be concluded from the above results that even low dose of BPA causes changes in the major organs of the body. Hence, it is suggested that BPA alternative should be used, so that public health status can be secured.
