Abstract
Abstract Environmental stress caused by pollution is often assessed by diversity of macro-invertebrate species in specific aquatic habitat. To find out seasonal fluctuations in various macro-invertebrates communities and different water quality parameters of River Zhob, a research trial was conducted on River Zhob, Balochistan. Samples of macro-invertebrates and water were taken from four different stations of River Zhob. A total 18 taxa of various macro-invertebrates were identified from the area. Phylum Arthropoda constitute 94.8% of the total population followed by Mollusca (3.6%) and Annelida (1.4%). A large number of arthropods were belonged to order Diptera (1148), while the order Trichoptera was stood second with respect to macro-invertebrate´s number (441). The maximum numbers of macro-invertebrates were observed in the month of January. All physico-chemical parameters of River Zhob such as air temperature, water temp, pH, dissolved oxygen (DO) and total dissolved solids (TDS) were within the range, suitable for the healthy growth of macro-invertebrates. Diversified populations of various macro-invertebrates confirm good ecological condition of environment and water in the studied site especially ample concentration of DO in River. The documented data on macro-invertebrates in studied site will provide a baseline for future research.

Abstract
Hyperglycaemia accelerates the aging process significantly. Diabetes problems can be mitigated by inhibiting glycation. To learn more about glycation and antiglycation mediated by methyl glyoxal and baicalein, we studied human serum albumin as a model protein. A Methylglyoxal (MGO) incubation period of seven days at 37 degrees Celsius induced glycation of Human Serum Albumin.s Hyperchromicity, decreased tryptophan and intrinsic fluorescence, increased AGE-specific fluorescence, and reduced mobility were all seen in glycated human serum albumin (MGO-HSA) in sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Fourier transform infrared spectroscopy (FT-IR) and then far ultraviolet dichroism were used to detect secondary and tertiary structural perturbations (CD). The Congo red assay (CR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) all verified the presence of amyloid-like clumps. Structure (carbonyl groups on ketoamine moieties) (CO), physiological problems including diabetes mellitus, and cardiovascular disease, etc. are linked to the structural and functional changes in glycated HSA, as proven by these studies.Communicated by Ramaswamy H.

Abstract
Recently, biosynthesized nanoparticles (NPs) have played a vital role as an alternative to physical and chemical methods. Here, a distinctive bioinspired synthesis of zinc oxide nanoparticles (ZnO NPs) has been introduced using leaf extracts of Withania coagulans as the reducing agent by using distilled water and methanol. The synthesized catalysts were analyzed through ultraviolet-visible spectroscopy, dynamic light scattering, scanning electron microscopy, Fourier transform infrared, energy-dispersive X-ray analysis, and X-ray diffraction for NP synthesis, morphology, functional group, elemental composition, and peak crystallinity analysis. The phytochemical analysis of 2,2-diphenyl-1-picrylhydrazyl (DPPH), total flavonoid content, total alkaloid content, and total phenolic content of the crude methanolic extract of the plant was also performed, suggesting the greatest potential as the supporting material for ZnO NPs. The NPs were investigated for their catalytic efficiency in the degradation of dyes (rhodamine B dye) and against important human food-borne pathogens (Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli). ZnO NPs exhibited a strong catalytic activity in the degradation of dyes and against bacteria. The results also showed an enhanced activity of ZnO NPs of methanolic extract (ZnO-M) composites compared to zinc oxide of distilled water (ZnO-D). The % age degradation of the dye, Kapp, and linear relationship were obtained from pseudo-first-order kinetics. The highest reduction rate in 30 and 60 min was observed under sunlight by ZnO-M and ZnO-D, respectively. The rate constant Kapp for the reduction of the dye was 13.6 × 10-1 min-1 and 6.8 × 10-1 min-1, respectively (numerical values). For ZnO-M, ln(Kapp) ≈ 0.309. For ZnO-D, ln(Kapp) ≈ -0.385. These rate constants represent the degradation of the dye in the presence of ZnO-M and ZnO-D catalysts. In addition, NPs were found to be most active against S. aureus (18 mm in the case of ZnO-M and 15 mm in the case of ZnO-D) than P. aeruginosa and E. coli. The results suggested that the prepared ZnO NPs could be used in pharmaceutical industries as well as photocatalysts. ZnO-M had greater control over particle size and morphology, potentially resulting in smaller, more uniform NPs. ZnO-D achieved fine size control but not potentially better than that compared to organic solvents.

Abstract
Breast cancer (BC) continues to be the most common cancer in the women worldwide. Since estrogen receptor (ER)-positive BC accounts for the majority of newly diagnosed cases, endocrine therapy is advised to utilize either tamoxifen (Tam) or aromatase inhibitors. The use of Tam as a monotherapy or in conjunction with an aromatase inhibitor following two or three years of endocrine therapy has long been recommended. When used adjuvantly, Tam medication reduces BC mortality and relapses, while it extends survival times in metastatic BC when used in conjunction with other treatments. Unfortunately, the efficiency of Tam varies considerably. This study was conducted to explore the influence of genetic polymorphisms in CYP2C19 gene on Tam's pharmacogenetics and pharmacokinetics in estrogen-positive BC patients. Data from healthy, unrelated individuals (n = 410; control group) and ER-positive BC patients (n = 430) receiving 20 mg of Tam per day were recruited. Steady-state plasma concentrations of Tam and its three metabolites were quantified using the high-performance liquid chromatography in the patients. The CYP2C19 polymorphisms were genotyped using an Amplification Refractory Mutation System-Polymerase Chain Reaction (ARMS-PCR) approach. More than 65% of healthy individuals were extensive metabolizers (*1/*1) for CYP2C19, whereas more than 70% of ER-positive BC patients were rapid and ultrarapid metabolizers (*1/17*, *17/17*). The polymorphism CYP2C19*17 is significantly associated with higher 4-hydroxytamoxifen (4-OH-Tam). Patients with the *17/*17 genotype exhibited 1- to 1.5-fold higher 4-OH-Tam, which was also high in patients with the *1/*2 and *2/*2 genotypes.

Abstract
Omega-3 fatty acids, including docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and α-linolenic acid (ALA), are essential polyunsaturated fatty acids with diverse health benefits. The limited conversion of dietary DHA necessitates its consumption as food supplements. Omega-3 fatty acids possess anti-arrhythmic and anti-inflammatory capabilities, contributing to cardiovascular health. Additionally, DHA consumption is linked to improved vision, brain, and memory development. Furthermore, omega-3 fatty acids offer protection against various health conditions, such as celiac disease, Alzheimer's, hypertension, thrombosis, heart diseases, depression, diabetes, and certain cancers. Fish oil from pelagic cold-water fish remains the primary source of omega-3 fatty acids, but the global population burden creates a demand-supply gap. Thus, researchers have explored alternative sources, including microbial systems, for omega-3 production. Microbial sources, particularly oleaginous actinomycetes, microalgae like Nannochloropsis and among microbial systems, Thraustochytrids stand out as they can store up to 50% of their dry weight in lipids. The microbial production of omega-3 fatty acids is a potential solution to meet the global demand, as these microorganisms can utilize various carbon sources, including organic waste. The biosynthesis of omega-3 fatty acids involves both aerobic and anaerobic pathways, with bacterial polyketide and PKS-like PUFA synthase as essential enzymatic complexes. Optimization of physicochemical parameters, such as carbon and nitrogen sources, pH, temperature, and salinity, plays a crucial role in maximizing DHA production in microbial systems. Overall, microbial sources hold significant promise in meeting the global demand for omega-3 fatty acids, offering an efficient and sustainable solution for enhancing human health.

Abstract
Advanced glycation end products (AGEs) are formed through non-enzymatic glycation, that have been linked to various diseases, including polycystic ovarian syndrome (PCOS) playing a critical role leading to secondary comorbidities such as diabetes-related problems, cardiovascular complications, infertility, etc. As a result, there has been a lot of research into AGE-inhibiting phytochemicals for the remediation and obstruct progression of glycation-related illnesses. The current study is based on in-vitro protein model, in which human serum albumin have been used to investigate the cumulative effect of chlorogenic acid (CGA) and cholecalciferol (vitamin D) on glycation and evaluate their inhibitory impact on AGEs production in the presence of methylglyoxal. Through the application of several biochemical and biophysical techniques, we were able to examine the synergistic impact of both the compounds on albumin structure and its biochemical properties during different stages of glycation. According to Nitro-blue tetrazolium assay results indicate that CGA and vitamin D inhibited fructosamine (early glycation product) production. Moreover, free thiol and lysine residues were significantly increased whereas protein carbonyl levels were significantly decreased. Additive effect of CGA and vitamin D were associated with reduced AGEs fluorescence and increased tryptophan and tyrosine fluorescence. Amadori-albumin after treatment showed some evidence of regaining its alpha-helicity as measured by far-UV CD spectrum. Furthermore, secondary structural alterations were confirmed by Fourier transform infrared spectroscopy (FTIR). ANS (1-anilinonaphthalene-8-sulfonic acid) fluorescence spectra also displayed less revelation of hydrophobic patches. Bilirubin binding capacity was also restored which showed functional recovery of HSA. The electrophoretic mobility was also restored which is portrayed by SDS-PAGE. Additionally, to predict the anti-aggregation potential of CGA and vitamin D, congo red assay and ThT fluorescence was performed which reveal low aggregate formation after treatment. These results corroborated with scanning electron microscopy and confocal microscopy. Docking and simulation results also reveal spontaneous binding of CGA and vitamin D on subdomain IIA of HSA favoring their binding thermodynamically. All the findings suggest that chlorogenic acid and cholecalciferol given in combination might help in prevention of PCOS progression and its related complications.

Abstract
Around the globe, plastic has been entering the aquatic system and is ingested by organisms. Identification, optimal digestion method, and characterization of the polymers to trace sources are of growing importance. Hence, the present work investigated microplastics accumulation, digestion protocol efficiency, and characterization of polymers with FTIR analysis in the guts of five fishes (Lethrinus nebulosus, Rastrelliger kanagurta, Acanthopagrus arabicus, Otolithes ruber, and Euryglossa orientalis) from the Karachi coastal area, Arabian Sea. A total of 1154 microplastics (MPs) were ingested by 29 out of 33 fish species (87%). The highest average MP/fish was recorded in Otolithes ruber (54) and the lowest in Rastrelliger kanagurta (19.42). Microfibers were the most abundant shape with the highest numbers (35.52%) as compared to the rest of the MPs identified. Transparent microfibers were recorded as the highest in numbers followed by red, black, blue, and green. In this study, KOH with different concentrations and exposure times along with oxidizing agent hydrogen peroxide was tested (Protocols 3 and 4). Results showed these bases were highly efficient in obtaining optimal digestion of the samples. FTIR analysis confirmed that the majority of the polymers found in the fish guts were polyethylene and polypropylene. This study validated for the first time the presence of these polymers of plastic in marine fish from Pakistan.

Abstract
The growing population increases the need to develop advanced biological methods for utilizing renewable and sustainable resources to produce environmentally friendly biofuels. Currently, energy resources are limited for global demand and are constantly depleting and creating environmental problems. Some higher chain alcohols, like butanol and ethanol, processing similar properties to gasoline, can be alternate sources of biofuel. However, the industrial production of these alcohols remains challenging because they cannot be efficiently produced by microbes naturally. Therefore, butanol is the most interesting biofuel candidate with a higher octane number produced naturally by microbes through Acetone-Butanol-Ethanol fermentation. Feedstock selection as the substrate is the most crucial step in biobutanol production. Lignocellulosic biomass has been widely used to produce cellulosic biobutanol using agricultural wastes and residue. Specific necessary pretreatments, fermentation strategies, bioreactor designing and kinetics, and modeling can also enhance the efficient production of biobutanol. The recent genetic engineering approaches of gene knock in, knock out, and overexpression to manipulate pathways can increase the production of biobutanol in a user friendly host organism. So far various genetic manipulation techniques like antisense RNA, TargeTron Technology and CRISPR have been used to target Clostridium acetobutylicum for biobutanol production. This review summarizes the recent research and development for the efficient production of biobutanol in various aspects.

Abstract
This study aimed to analyse the diagnostic accuracy of different laboratory parameters that can predict bone marrow metastasis. A cross-sectional analytical study was conducted at the Armed Forces Institute of Pathology (AFIP), Rawalpindi from March 2021 to August 2021. Bone marrow aspirates and biopsy procedures were done on 60 newly diagnosed cases of non-haematological malignancies as part of staging. Laboratory parameters noted for the study included peripheral blood smear findings, serum lactate dehydrogenase (LDH), radiological findings, and bone marrow aspirate/trephine biopsy results. Bone marrow metastasis was seen in 21/60 patients. The most common malignancies with bone marrow involvement were retinoblastoma and neuroblastoma. Laboratory findings showed no significant statistical difference in mean haemoglobin and total leukocyte count between cases and controls. Positive cases had a mean platelet count of 261.7 x 109/L and mean LDH of 750.1 U/L (p <0.05) for both parameters. ROC analysis showed the area under the curve (AUC) for LDH to be 0.969 (highly significant) showing a strong predictive value of LDH. Positive radiological findings were detected in only one case with bone marrow metastasis. The elevated level of serum LDH is not only cost-effective but also has high diagnostic accuracy to predict bone marrow metastasis. Key Words: Bone marrow, Biochemical, Lactate dehydrogenase, Metastasis, Non-haematological malignancies.

Abstract
Soil contamination with toxic heavy metals [such as lead (Pb)] is becoming a serious global problem due to the rapid development of the social economy. However, accumulation of Pb in plant parts is very toxic for plant growth and decreases crop yield and productivity. In the present study, we have investigated the different concentrations of Pb in the soil i.e., [0 (no Pb), 50, and 100 mg kg-1] to study plant growth and biomass, photosynthetic pigments and gas exchange characteristics, oxidative stress indicators and the response of various antioxidants (enzymatic and non-enzymatic), nutritional status of the plant, organic acid exudation pattern and also Pb accumulation in the roots and shoots of the plants of two varieties of tomato (Solanum lycopersicum L.) i.e., Roma and Cchuas, grown under different levels of synergic acid [no spray (NS), water spray (WS), 0.3-0.5°μM]. Results from the present study showed that the increasing levels of Pb in the soil decreased non-significantly (P < 0.05) shoot length, root length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, chlorophyll-a, chlorophyll-b, total chlorophyll, carotenoid content, net photosynthesis, stomatal conductance, transpiration rate, soluble sugar, reducing sugar, non-reducing sugar contents, calcium (Ca2+), magnesium (Mg2+), iron (Fe2+), and phosphorus (P) contents in the roots and shoots of the plants. However, Pb toxicity also induced oxidative stress in the roots and shoots of the plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2), and electrolyte leakage (EL) which also induced increased the compounds of various enzymatic and non-enzymatic antioxidants and also organic acids exudation pattern in the roots such as fumaric acid, acetic acid, citric acid, formic acid, malic acid, oxalic acid contents and increased the concentration of Pb in different parts of the plants. Results also show that the Cchuas showed better growth and development compared to Roma, under the same levels of Pb in the soil. The alleviation of Pb toxicity was induced by the application of synergic acid, and results showed that the application of synergic acid increased plant growth and biomass and also increased the gas exchange characteristics and antioxidant capacity in the roots and shoots of the plants. Research findings, therefore, suggested that synergic acid application can ameliorate Pb toxicity in S. lycopersicum varieties and result in improved plant growth and composition under metal stress as depicted by balanced exudation of organic acids.

Abstract
Cancer is one of the most diagnosed and life threatening disease throughout the world. Nevertheless present day clinical management for cancers are surgery, radiations which are insufficient to contain the disease burden. In the past two decades, more than half of chemotherapeutic drugs developed are either directly or indirectly dependent on medicinal base phytocompounds or their derivative. The present study aims to provide the base for chemotherapeutic phytochemicals. Fagonia indica showed significant antimutagenic potential with reference to control IC50 values were calculated as 146.33±5.2μg/ml, TA100 (AZS) 105.33±4.0μg/ml, TA98 (2AA) 113.6±5.2μg/ml followed and TA98 (AZS) 112.6±4.4 in Ames test. For this reason, the antiproliferation effect of extracts on cancer cell lines was studied through resazurin fluorescence. On HepG-2 cell lines 50% cytotoxic concentration (CC50) of (FIWM) was recorded as 128.3±,2.43μg/ml. On the homo sapiens epithelial cell of lung tissue (A549), the high throughput instrumental analysis of Fagonia indica depicts maximum cytotoxic effect in 30hr. The electrical impedance displays the real-time evidence about qualitative apoptosis expressed. The impedance results were supported as palmitic acid from Fagonia indica virtually that inhibits Cyclin Dependent Kinase 2 (CDKs 2) in silico molecular docking studies. Fagonia indica extract possesses substantial antimutagenic, cytotoxic and anticancer activity which supports the potential of its phytochemicals for drug development.

Abstract
Soybean meal is an inexpensive plant origin protein which has been used in practical diets as a replacement of animal protein such as fish meal or chicken meal, due to the uneconomical price of animal protein diets. Consequently, a research study was conducted on some commercial species of Indian major carps i.e. Catla (Cattla cattla), Rohu (Labeo rohita) and Mrigala (Cirhinus mrigala) (Hamilton, 1822) to estimate optimum dietary protein requirement of soy bean meal in diet in an intensive polyculture. Three different diets (SBM I, SBM II and SBM III) were formulated by 80%, 50% and 20% replacement of fish meal with soybean meal from a 45% fish meal diet (control).Highest monthly mean weight gain was obtained by SBM II (with 35% CP and about 50% substitution of fish meal), while SBM III (45% Crude Protein and about 20% substitution of fish meal) was stood second. All tested diets respond enormously by producing high yield as compare to control diet, though SBM II generated highest yield among all. On the bases of the following research, it was revealed that the SBM can surrogate even50% fish meal without any augmentation of other amino acids in the diet of Indian major carps.

Abstract
Purpose: To investigate the association of *2 and *17 single nucleotide polymorphisms (SNPs) of CYP2C19 gene with hypertension in Pakistani population.
Methods: The study was conducted on 527 hypertensive patients and 530 unrelated healthy controls from selected regions of Pakistan. DNA was extracted from leukocytes and all patients and controls were genotyped for two SNPs (rs4244285 and rs12248560) of CYP2C19 gene by allele specific polymerase chain reaction (AS-PCR).
Results: Multi-allelic polymorphism in CYP2C19 identified four distinct phenotypes known as ultra-rapid metabolizer (UM), extensive metabolizer (EM), intermediate metabolizer (IM) and poor metabolizer (PM) in hypertensive patients and controls. For CYP2C19*2 polymorphisms, overall wild type and mutant allele frequency were 75 and 25 % in hypertensive patients, and 64.2 and 35.8 % in controls. For CYP2C19*17 polymorphisms, the overall wild type and mutant allele frequency were 66.6 and 33.4 % in hypertensive patients and 75.6 % and 24.4 % in controls. Significant difference in allele frequencies for CYP2C19*2 and *17 was demonstrated between hypertensive and non-hypertensive subjects.
Conclusion: To the best of our knowledge, this is the first report on CYP2C19 frequencies in hypertensive Pakistani patients. The finds should help clinicians to determine a suitable optimal dosage of some drugs in order to reduce side effects.

Abstract
The in silico molecular dynamics and structure-based site-specific drug design of indigenous plant biomolecules and selected proteins have remarkable potential for cancer therapy. A set of five proteins included for this research were epidermal growth factor protein (PDB ID; 1M17), crystal structure of mutated EGFR kinase (PDB ID; 2EB3), crystal structure of Bcl-xl (PDB ID; 2YXJ), apoptosis regulator protein MCL-1 BH3 (PDB ID; 3MK8) and apoptosis proteins (PDB ID; 5C3H). The present study on in silico investigation of fifteen indigenous medicinal plants were selected there one hundred thirty four ligands available literature were docked against five proteins involved in carcinogenesis. The highest scoring in silico plant, Fagonia indica was subjected to in vitro cytotoxic effects on HCT116, HepG-2 and HeLa human carcinoma cell lines. Molecular dynamics showed best ligand-protein inhibition interaction between Coumarin-2xyj and Kaempferol-2eb3 with promising binding affinities. Whereas, on HeLa human cervical cancer cell line IC50 was 28.3±0.102/ml. Fagonia indica could be potential source from natural products that have cytotoxic properties against cervical cancer cells by blocking mutant epidermal growth factor tyrosine or peroxisome proliferators activated receptor proteins.

Abstract
Atrial fibrillation (AF) is a common arrhythmia in patients with mitral regurgitation (MR) undergoing transcatheter mitral valve repair (TMVR). In this systematic review, we aimed to investigate the outcomes of TMVR using MitraClip in AF patients. We performed a systematic search using PubMed, SCOPUS, EMBASE, and Google Scholar, from inception to May 10, 2020, for studies that reported outcomes following MitraClip, in patients with AF versus without AF. Seven studies with a total of 7678 patients met the inclusion criteria. The risk of 1-year all-cause mortality following TMVR was higher in AF patients (RR 1.40, 95% CI 1.27-1.54, p ≤ 0.001). Similarly, the risk of heart failure hospitalization was higher in patients with AF (RR 1.17, 95% CI 1.06-1.30, p = 0.002) and the risk of bleeding was elevated in AF patients (RR 1.29, 95% CI 1.15-1.45, p ≤ 0.001). The risk of procedural failure, in-hospital mortality, cardiovascular mortality, and stroke was not significantly different between the two groups. The higher risk of all-cause mortality, HF hospitalization, and risk of bleeding in AF patients undergoing MitraClip warrants attention.

Abstract
Neurotoxicity is a rare side effect of Cefepime use. Cefepime can cross the blood-brain barrier and can be neurotoxic by competitive albeit weak antagonism of the gamma-aminobutyric acid complex. It is cleared by the kidneys which puts individuals with renal impairment at risk of side effects. We describe a case of Cefepime neurotoxicity in the context of nephrotoxicity secondary to the use of other drugs.

Abstract
Vasospastic angina (VSA) is characterized by episodic chest pain associated with transient ST-segment abnormalities on electrocardiogram, secondary to vasospasm of the epicardial coronary artery. We report the rare case of a 46-year-old female with refractory VSA secondary to multivessel coronary vasospasm causing an anterior myocardial infarction. She succumbed secondary to ventricular tachycardia (VT) storm, in spite of being on maximally tolerated medical therapy and having an implantable cardioverter defibrillator (ICD) for secondary prevention of VT. Contemporary guidelines recommend ICD implantation (class IIa) in VSA patients who survived sudden cardiac arrest (SCA), if they are already on optimal medical therapy or if medical therapy is not tolerated. Whether ICD implantation is appropriate in VSA patients with aborted SCA, even before assessing the response to medical therapy, is not well known and requires further studies.

Abstract
Lyme disease is a multisystemic infection that can present as localized disease, early disseminated, or late disease. During the early disseminated phase of Lyme disease, the hematogenous spread can result in extracutaneous manifestations, including cardiac, neurological, and joint. Lyme carditis is an uncommon manifestation occurring in patients with untreated Lyme disease. Third-degree atrioventricular (AV) block is a rarer entity. We present a case of a 21-year-old female with no significant past medical history admitted with third-degree AV block and thereby highlighting this uncommon presentation.

Abstract
Sickle cell disease (SCD) affects approximately 100,000 Americans, and it occurs in one out of every 365 African American births. Cardiac complications are a common feature of SCD and are an essential cause of the morbidity and mortality associated with SCD. However, there is insufficient literature on SCD and atrioventricular (AV) blocks. We present a case of a young African American male with transient second-degree Mobitz type 1 block during an acute episode of sickle cell crisis.

Abstract
Chemotherapy-induced cardiotoxicity is a known condition, however, bortezomib and melphalan do not typically cause cardiotoxicity. With the rise in the use of newer chemotherapeutic agents, it is important to identify and understand the cardiac implications of chemotherapeutic agents. We present a case of a 70-year-old female with no known significant cardiac history presenting with partially reversible cardiomyopathy with initial presentation only being as sinus tachycardia.

Abstract
Obstructive sleep apnea (OSA) is highly prevalent in the United States (US). Along with epidemic rates of obesity, the rate of OSA cases is also on the rise. OSA is associated with multiple chronic health conditions, including hypertension, diabetes, stroke, myocardial ischemia, and heart rhythm disturbances. OSA is commonly treated with continuous positive airway pressure (CPAP) therapy. Several reports indicate that effective treatment of OSA can reduce the risk of cardiovascular diseases, including cardiac arrhythmias, especially atrial fibrillation (AF). CPAP therapy helps to maintain sinus rhythm after interventions such as electrical cardioversion and catheter ablation in patients with AF. However, more data is required to establish a relationship between OSA and other atrial arrhythmias as well to evaluate the effect of CPAP. This review will compile the latest evidence on the pathophysiology, management, and treatment of atrial arrhythmias associated with OSA.

Abstract
Emphysematous gastritis is a rare disease with gastric inflammation and intramural gas formation due to gas-forming microorganisms. It is diagnosed based on clinical presentation and imaging findings of gas in the gastric wall. Computed tomography is the preferred imaging modality. Early diagnosis and management are important since emphysematous gastritis is associated with high rates of morbidity and mortality. We present a case of emphysematous gastritis, which was successfully managed conservatively through early diagnosis and prompt treatment.

Cyanosis in the setting of topical anesthetic use, along with the arterial blood gas results indicating hypoxemia, points towards the diagnosis of methemoglobinemia. We highlight the potential complication with the use of topical pharyngeal benzocaine through this case presentation.

Abstract
Introduction Non-variceal upper gastrointestinal bleeding (UGIB) is a major burden on the health care system. The timing of endoscopy has been an ongoing debate and data on the association of early endoscopy with a better or worse clinical outcome are conflicting. In our study, we aimed to identify the benefits versus the risks of performing an urgent endoscopy in regards to the number of endoscopic interventions, length of hospital stay, number of packed red blood cells (PRBCs) transfused, and mortality. Methodology This is a retrospective record-based study. A total of 806 charts were reviewed and 251 patients with the signs and symptoms of UGIB on presentation were included in the study. Patients with variceal bleeding, lower gastrointestinal bleeding, insignificant bleeds with no drop in H/H, GI bleed not being the presenting complaint on admission, and patients on anticoagulation were excluded. Results Out of the patients who underwent an urgent esophagogastroduodenoscopy (EGD), 26.2% needed a second-look EGD 48 hours after the first EGD when compared to 4% and 2% in the early (12-24 hours) and late (>24 hours) endoscopy groups, respectively. In patients who underwent urgent EGD, 23% had active bleeding and it was statistically significant when compared to the other groups. The active bleeding limited the visualization during the endoscopy, which led to a repeat EGD in the urgent EGD group. If an endoscopic intervention was received, patients having EGD >24 hours received a smaller number of interventions. There was no statistical difference in the Blatchford scores between the three groups, indicating that the groups were similar in morbidity. No difference in mortality, hospital length of stay, or number of blood transfusions received, surgical or interventional radiology-guided interventions was found between the three groups. Conclusion Patients who underwent urgent endoscopy had more procedures, with no difference in mortality, number of units of blood transfused, or length of hospitalization when compared to the early or late endoscopy groups.

Abstract
CYP2D6 belongs to a family of Cytochrome P450 and is involved in metabolism of a number of commonly prescribed drugs. This study was designed to identify *4 allelic frequency of CYP2D6 in Pakistani population. The ethno-geographic variations in the CYP2D6 alleles are responsible for varied expression of this enzyme and thus influence the metabolic rate and efficacy of prescribed drugs. In total, 976 volunteers belonging to 16 different ethnic groups of Pakistan were screened for CYP2D6*4 polymorphism. The *4 allele was detected in all the ethnic groups with varied frequency ranging from 3.73%-13.64% and an overall average of 7.22% in different ethnic groups of the population. Maximum frequency was detected in northern Pakistani population including Meo (13.64%), Punjabi (11.96%) and Pathan (10.42%). Low frequency (<4%) of*4 polymorphism was observed in Kalash and Makrani groups, whereas an intermediate frequency (5-9%) was observed in all the other ethnic groups. The data indicates that despite ethnic diversity poor metabolizers in Pakistani population are expected to carry CYP2D6*4 allele at a relatively higher frequency than most other Asian populations. (Word count = 186).

Abstract
Cancers are caused by the defects in apoptosis process which leads to uncontrolled proliferation, therefore, most attractive drug target discovery strategy is to find ligands which have the ability to activate or regulate the apoptotic machinery. Peroxisome-proliferator-activated receptors (PPARs) are nuclear hormone receptors their over expression is observed in many tumours and contributes to chemotherapy resistance. The goal of this study to scrutinized antitumor phytochemicals from Alysicarpus bupleurifolius, Piper nigrum and Plumeria obtuse and potential energy values render from interactions between active site residues and ligands. The potential phytochemicals with significant binding affinity are ursolic acid, cis-4-decenoic acid and p-coumaric acid respectively most effective compounds in high throughput virtual screening belongs to Plumeria obtuse against PPARs associated with tumour development and progression. This modern drug designing modeling in silico approach, therefore, identifies the potential leads against over expressed tumours.

Abstract
Pierce's disease (PD) limits the cultivation of Vitis vinifera grape cultivars in California, across the southern United States and into South America. Resistance has been well characterized in V. arizonica, and one resistance locus has been identified (PdR1). However, resistance is poorly characterized in most other grape species. We tested a wide range of Vitis species from the southwestern United States for resistance to PD and used nuclear and chloroplast markers to phenotypically and genetically select a diverse set of resistant accessions. Chloroplast SSR markers identified 11 maternal lineage lines within the set of 17 (14 new and three previously identified) PD resistant accessions. A total of 19 breeding populations (F1 and pseudo-BC1) were developed with the 14 PD resistant accessions, and a total of 705 seedlings were analyzed for PD resistance. Using a limited mapping approach, 12 SSR markers, linked to the PdR1 locus, were used to genotype the breeding populations and phenotypic data were analyzed. Nine accessions had a major resistance quantitative trait locus (QTL) within the genomic region containing PdR1. The phenotypic data for these three resistant accessions, ANU67, b41-13, and T03-16, did not associate with PdR1 linked markers, indicating that their resistance is located in other regions of the genome. These three accessions were identified as candidates for use in the development of framework maps with larger populations capable of detecting additional and unique loci for PD resistance breeding and the stacking of PD resistance genes.
