Abstract
Background The recent COVID vaccinations have successfully reduced death and severity but did not stop the transmission of viruses by the emerging SARS-CoV-2 strain. There is a need for better and long-lasting dynamic vaccines for numerous prevailing strains and the evolving SARS-CoV-2 virus, necessitating the development of broad-spectrum strains being used to stop infection by reducing the spread rate and re-infection. The spike (S) glycoprotein is one of the proteins expressed commonly in the early phases of SARS-CoV-2 infection. It has been identified as the most immunogenic protein of SARS-CoV-2. Methods In this study, advanced bioinformatics techniques have been exploited to design the novel multi-epitope vaccine using conserved S protein portions from widespread strains of SARS-CoV-2 to predict B cell and T cell epitopes. These epitopes were selected based on toxicity, antigenicity score and immunogenicity. Epitope combinations were used to construct the maximum potent multi-epitope construct with potential immunogenic features. EAAAK, AAY, and GPGPG were used as linkers to construct epitopes. Results The developed vaccine has shown positive results. After the chimeric vaccine construct was cloned into the PET28a (+) vector for expression screening in Escherichia coli, the potential expression of the construct was identified. Conclusion The construct vaccine performed well in computer-based immune response simulation and covered a variety of allelic populations. These computational results are more helpful for further analysis of our contract vaccine, which can finally help control and prevent SARS-CoV-2 infections worldwide.

Abstract
In the surgery-first approach (SFA), orthognathic surgery is performed without the need for presurgical orthodontic treatment. This study was aimed at assessing the treatment durations and occlusal outcomes for a consecutive cohort of patients, with a range of dentofacial deformities, who had completed orthognathic treatment using SFA. The duration of orthognathic treatment was measured. The overall change in occlusion, and the quality of the final occlusion, were evaluated using the patients' study casts. A single, independent, calibrated operator carried out the occlusal scores, using the validated Peer Assessment Rating (PAR) index. This was repeated to test intraoperator reliability. A total of 51 patients completed surgery-first treatment during the study period. The mean (range) age at surgery was 23.3 (15-47) years. The pre-treatment skeletal jaw relationship was Class III in 39 cases, and Class II in 12 cases. The mean (SD) overall treatment duration was 11.7 (5.7) months. The intraexaminer reliability of assessing the occlusion was high. The PAR scores confirmed a significant improvement in the quality of occlusion at the completion of treatment, which compares favourably with previous studies on the conventional orthodontics-first approach. The surgery first approach can be effective at correcting both Class II and Class III malocclusion types with reduced treatment times.

Abstract
Cotton is an important cash crop in addition to being a fiber commodity, and it plays an essential part in the economies of numerous nations. High temperature is the most critical element affecting its yield from fertilization to harvest. The optimal temperature for root formation is 30 C -35 °C; however, root development ends around 40 °C. Increased temperature, in particular, influences different biochemical and physiological processes associated with cotton plant, resulting in low seed cotton production. Many studies in various agroecological zones used various agronomic strategies and contemporary breeding techniques to reduce heat stress and improve cotton productivity. To attain desired traits, cotton breeders should investigate all potential possibilities, such as generating superior cultivars by traditional breeding, employing molecular techniques and transgenic methods, such as using genome editing techniques. The main objective of this review is to provide the recent information on the environmental factors, such as temperature, heat and drought, influence the growth and development, morphology and physio-chemical alteration associated with cotton. Furthermore, recent advancement in cotton breeding to combat the serious threat of drought and heat stress.

Abstract
Automatic classification of Lyme disease rashes on the skin helps clinicians and dermatologists' probe and investigate Lyme skin rashes effectively. This paper proposes a new in-depth features fusion system to classify Lyme disease rashes. The proposed method consists of two main steps. First, three different deep learning models, Densenet201, InceptionV3, and Exception, were trained independently to extract the deep features from the erythema migrans (EM) images. Second, a deep feature fusion mechanism (meta classifier) is developed to integrate the deep features before the final classification output layer. The meta classifier is a basic deep convolutional neural network trained on original images and features extracted from base level three deep learning models. In the feature fusion mechanism, the last three layers of base models are dropped out and connected to the meta classifier. The proposed deep feature fusion method significantly improved the classification process, where the classification accuracy was 98.97%, which is particularly impressive than the other state-of-the-art models.

Abstract
OBJECTIVE To compare and correlate safety climate standards and safety practices among different subspecialities of pathology. STUDY DESIGN Cross-sectional study. Place and Duration of the Study: The study was conducted at Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from February to November 2022. METHODOLOGY Responses of 199 participants were recorded according to the validated Nordic Safety Climate Questionnaire (NOSACQ-50) and Lab Safety Survey form. The safety climate presented as seven dimensions according to the validated questionnaire was compared among different workgroups, based on subspeciality and job designation, using one-way ANOVA and independent sample t-test, respectively. Pearson's correlation was used to assess the relationship between the safety climate and safety practices. RESULTS Among the safety climate dimensions, safety communication, trust in co-workers' safety competence (M=3.02) and workers trust in efficacy of safety systems (M=3.00) were the most positively perceived aspects followed by management's safety priority (M=2.98). Comparison of subspecialities showed significant differences in management safety empowerment, management safety justice, workers' safety commitment, safety communication, and trust in efficiency of safety systems (p<0.001 for all 5 factors). Chemical pathology workers and technical staff were workgroups with lower safety climate scores. A statistically significant positive correlation (r=0.97) was observed between the safety procedures and safety climate at an organisational level. CONCLUSION The results demonstrated the existence of a good safety climate within the participating laboratories of the institute. It successfully identified areas that need further safety improvements. The study will help increase awareness about occupational safety and safety culture among healthcare workers in general and clinical laboratory setups in particular.

Abstract
PURPOSE/OBJECTIVE(S) Radiopharmaceutical therapy (RPT) has demonstrated promise in the treatment of neuroendocrine and prostate cancer. Due to the highly varied biodistribution and non-homogeneity of total integrated dose across cancer patients, a system for real-time dosimetry based on continuous measurement is desirable to deliver sufficient dose for tumor ablation while preventing toxicity from off-target uptake by organs at risk (OAR). Single time point imaging (mostly SPECT)-based dosimetry offers a snapshot of the body-wide dose distribution at a given time point, but even single SPECT imaging is generally limited in availability, often leading to significant inaccuracies in estimating total integrated dose. Therefore, accurate personalized dosimetry in RPT is an unmet need and requires continuous dosimetry measurements of tumors and OARs across multiple half-lives of the therapeutic radiopharmaceutical. Using a priori knowledge of tumor and OAR locations from pretherapy imaging, we have developed a novel algorithm that utilizes a network of custom uncollimated, optical fiber-based γ-counting probes to isolate the real-time in vivo tumor and OAR uptake in 177Lu-PSMA-617 and 225Ac-MACROPA-YS5 therapy. MATERIALS/METHODS The proposed system was successfully validated in athymic mice models bearing varying numbers of tumors from two human prostate cancer cell lines (PC3-pip, PC3-flu). Uncollimated γ counts using the developed probes were acquired outside of the mice for 10 minutes, starting at 0 hr, 6 hrs, 12 hrs, 24 hrs, and 48 hrs after the injection of 177Lu-PSMA-617. The percent injected activity per mL of tissue (%IA/mL) of each tumor and OAR was reconstructed at every time point and compared to the %IA/mL extracted from SPECT/CT immediately after the recording. RESULTS The developed system's %IA/mL reconstruction in PC3-pip tumors, PC3-flu tumors, kidneys, and bladders is highly correlative with the %IA/mL extracted from state-of-art in vivo dosimetry techniques, with %IA/mL ranging from 0.1% to 160% assuming a 29.6 MBq 177Lu-PSMA-617 administration. The least squares linear regression fit between the reconstructed activity and the activity measured from SPECT/CT is given by Estimated %IA/mL = 0.91 x SPECT %IA/mL, with an R2 of 0.991, and Pearson's r of 0.9975. There is a nearly 1:1 mapping between the proposed model and SPECT/CT. CONCLUSION A novel dose reconstruction algorithm for personalized dosimetry in RPT that utilizes a sparse set of external γ-counters and a priori knowledge of tumor and OAR locations was developed and validated in in vivo human prostate cancer murine models. The proposed system enables continuous dosimetry measurements of multiple tumors and OAR noninvasively, with high accessibility, high temporal resolution, and across multiple classes of ɑ and β-based RPT. Similar experiments using 225Ac-MACROPA-YS5 are ongoing and additional results will be reported.

Abstract
Osteoporosis is a skeletal disease that is commonly seen in older people but often neglected due to its silent nature. To overcome the issue of osteoporosis in men and women, we proposed an advanced prediction model with the help of machine learning techniques which can help to identify the potential occurrence of this bone disease by its advanced screening tools. To achieve more reliable and accurate results, various machine-learning techniques were applied to the presented data sets. Moreover, we also compared the performance of our results with other existing algorithms to solely focus on the advanced features of the proposed methodology. The two data sets, the clinical tests of patients in Taiwan and medical reports of postmenopausal women in Korea through Korean Health and Nutrition Examination Surveys (2010-2011) were considered in this study. To predict bone disorders, we utilized the data about females and developed a system using artificial neural networks, support vector machines, and K-nearest neighbor. To compare the performance of the model Area under the Receiver Operating Characteristic Curve and other evaluation metrics were compared. The achieved results from all the algorithms and compared them with Osteoporosis Self-Assessment Tool for Asians and the results were noticeably better and more reliable than existing systems due to the involvement of ML. Using machine learning techniques to predict these types of diseases is better because physicians and patients can take early action to prevent the consequences in advance.

Abstract
Soybean is a leguminous crop known for its efficient nitrogen utilization and ease of cultivation. However, its intercropping with maize may lead to severe reduction in its growth and yield due to shading effect of maize. This issue can be resolved by the appropriate application of essential plant nutrient such as molybdenum (Mo). Aim of this study was to assess the effect of Mo application on the morphological and physiological characteristics of soybean intercropped with maize. A two-year field experiment was conducted for this purpose, and Mo was applied in the form of sodium molybdate (Na2MoO4), and four different levels were maintained i.e., 0, 60, 120 and 180 g ha-1. Soybean exhibited varying responses to different levels of molybdenum (Mo) application. Notably, in both sole and intercropped cropping systems, the application of Mo at a rate of 120 g ha-1 demonstrated the highest level of promise compared to other application levels. However, most significant outcomes were pragmatic in soybean-maize intercropping, as application of Mo @ 120 g ha-1 significantly improved soybean growth and yield attributes, including leaf area index (LAI; 434 and 441%), total plant biomass (430 and 461%), transpiration rate (15 and 18%), stomatal conductance (9 and 11%), and yield (15 and 20%) during year 2020 and 2021 respectively, as compared to control treatment. Similarly, Mo @ 120 g ha-1 application resulted in highest total grain yield (626.0 and 725.3 kg ha-1) during 2020 and 2021 respectively, which exceeded the grain yields of other Mo levels under intercropping. Moreover, under Mo application level (120 g ha-1), grain NPK and Mo contents during years 2020 and 2021 were found to be 1.15, 0.22, 0.83 and 68.94 mg kg-1, and 1.27, 0.25, 0.90 and 72.18 mg kg-1 under intercropping system increased the value as compared to control treatment. Findings of current study highlighted the significance of Mo in enhancing soybean growth, yield, and nutrient uptake efficiency in maize-soybean intercropping systems.

Abstract
Respiratory tract infection (RTI) remains a significant cause of morbidity and mortality across the globe. The optimal management of RTI relies upon timely pathogen identification via evaluation of respiratory samples, a process which utilises traditional culture-based methods to identify offending microorganisms. This process can be slow and often prolongs the use of broad-spectrum antimicrobial therapy, whilst also delaying the introduction of targeted therapy as a result. Nanopore sequencing (NPS) of respiratory samples has recently emerged as a potential diagnostic tool in RTI. NPS can identify pathogens and antimicrobial resistance profiles with greater speed and efficiency than traditional sputum culture-based methods. Increased speed to pathogen identification can improve antimicrobial stewardship by reducing the use of broad-spectrum antibiotic therapy, as well as improving overall clinical outcomes. This new technology is becoming more affordable and accessible, with some NPS platforms requiring minimal sample preparation and laboratory infrastructure. However, questions regarding clinical utility and how best to implement NPS technology within RTI diagnostic pathways remain unanswered. In this review, we introduce NPS as a technology and as a diagnostic tool in RTI in various settings, before discussing the advantages and limitations of NPS, and finally what the future might hold for NPS platforms in RTI diagnostics.

Abstract
Serum Magnesium plays a significant role in different diabetic complications. This comparative cross sectional study was conducted to evaluate serum magnesium levels in patients with Type 2 Diabetes Mellitus (T2DM) with and without nephropathy. A total of 182 diabetic patients (91 with nephropathy and 91 without nephropathy) were included. Odds ratio were calculated and Mann Whitney U test was used to compare quantitative variables; p<0.05 was considered significant. The results showed that 64/91 (70.3%) patients with nephropathy had hypomagnesaemia as compared to 21/91 (23.07%) patients without nephropathy. The risk of hypomagnesaemia was higher in patients with nephropathy than without nephropathy (Odds ratio 2.7 vs 0.34). Median magnesium levels (1.73 mg/dl) were lower in patients with nephropathy as compared to patients without nephropathy (2.09 mg/dl), p<0.01. It is concluded that magnesium levels were significantly lower in patients with diabetic nephropathy as compared to without nephropathy.

Abstract
OBJECTIVE To determine the correlation of serum erythropoietin concentration with diabetic retinopathy in patients with type 2 diabetes mellitus. STUDY DESIGN Cross-sectional study. Place and Duration of the Study: Department of Chemical Pathology and Endocrinology, Armed Forces Institute of Pathology (AFIP), Rawalpindi, from July to December 2021. METHODOLOGY A total of 180 individuals were enrolled in the study and placed in 2 groups as group 1 have 90 cases of type 2 diabetes mellitus and group 2 having 90 age-matched healthy controls. Group 1 was further subclassified into proliferative diabetic retinopathy (PDR) and non-proliferative diabetic retinopathy (NPDR) subgroups by an expert ophthalmologist. Serum erythropoietin, creatinine, blood HbA1c, and haemoglobin were analysed. Correlation between stages of proliferation and serum erythropoietin, creatinine, blood HbA1c, and haemoglobin were analysed. An independent-sample student t-test was applied to compare mean Serum erythropoietin between PDR and NPDR groups. Pearson's correlation was applied among disease severity, and type of retinopathy. A p-value of ≤0.05 was considered significant. RESULTS The average age of participants in groups 1 and 2 was 45.88±8.6 and 56.6±10.23 years, respectively. More males (n=60, 66.7%) were noted in cases compared to controls (n=42, 46.7%). serum erythropoietin concentration observed in cases (8.4±1.87 IU/L) was higher than controls (6.50±0.9). The mean serum erythropoietin concentration in PDR (9.35±1.74 IU/L) was significantly greater than that in NPDR (7.3±1.38 IU/L, p <0.001). The serum concentration of erythropoietin in group 1 increased linearly with the severity of the disease (r=0.103). CONCLUSION Serum erythropoietin concentrations increased in uncontrolled type 2 diabetics more so in proliferative retinopathy cases, and increased with disease severity. KEY WORDS Erythropoietin, Diabetic retinopathy, Proliferative diabetic retinopathy.

Abstract
Phase change material (PCM)-based thermal energy storage units (TESU) have very low thermal conductivity that compromise their charging and discharging rate. The present study focuses on an enhancement in charging rate as well as an increase in the uniformity of the melting rate. A rectangular cavity consisting of two horizontal partial fins is studied. The horizontal partial fins are placed symmetrically in a PCM-based TESU. In the current work, the melting rate of PCM was enhanced using asymmetric arrangement while keeping all other parameters the same, thus showing the positive effect of asymmetric configuration in such storage systems. The position and the pitch of each fin is optimized to improve heat transfer characteristics of the TESU. The numerical investigation of the problem is performed. TESU with asymmetrically placed fins show better performance in terms of higher charging rate as well as uniformity of the charging rate. The asymmetric placement of the fins suggested by present study increased the charging rate by 74.3% on average as compared to the symmetrically placed fins in the storage system. The charging rate uniformity is improved by 43.7%. The asymmetric fin's placement conserved the convection strength for a longer melting duration and so increased the Nusselt number by 80.2% as compared to the symmetrically placed fins. Thus, it can be concluded that the performance of asymmetric fins is better in the charging of PCMs than the symmetrically placed fins in a PCM-based TESU.

Abstract
Research on entrepreneurship in family firms has grown exponentially over the past two decades. Due to the various theoretical perspectives and contexts found here however, this body of research remains fragmented, with a unified understanding of the current state of knowledge and the opportunities for future research in the field continuing to lack. In this study, we address this gap by conducting an updated bibliometric analysis of the research on entrepreneurship in family firms. Here we integrate two different bibliometric methods to provide a more comprehensive picture of the field, unveiling its intellectual foundations and current research discourses and how these two are related. To do this, we first conduct a co-citation analysis clustering the intellectual foundations of the research on entrepreneurship in family firms. Second, a bibliographic coupling of recent publications from 2010 to 2021 provides a transparent structure of current research discourses. Third, analyzing which intellectual foundations are primarily cited in each current research stream unveils the dominant theoretical paradigms in the current state of research. Analyzing 570 published studies, we identified four intellectual foundations of entrepreneurship in family firms: socioemotional wealth (SEW), entrepreneurial orientation, family-embedded resources, and agency theory. The current research can be clustered into seven main discourses: entrepreneurial motivation, gender and success, entrepreneurial orientation, individual and firm-level characteristics, the family embedded network, family firm internationalization, and family heterogeneity. An integrative network diagram provides an overview of the research field’s development while also identifying the gaps to be addressed by future research.

Abstract
Objective: To evaluate the effect of type 2 diabetes mellitus on plasma N-terminal prohormone B-type natriuretic peptide levels in patients with heart failure and correlate it with glycosylated haemoglobin levels.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: Department of Chemical Pathology in collaboration with the Department of Cardiology,Combined Military Hospital, Multan Pakistan, from Feb to Sep 2021.
Methodology: We assayed plasma NT-pro BNP levels in 194 individuals with established heart failure, (98 non-diabetics, and 96 patients with diabetes). Plasma NT-pro BNP levels were compared between groups in addition, the correlation of glycosylated haemoglobin with plasma NT-pro BNP levels was explored.
Results: The mean plasma NT-pro BNP values were higher in patients with diabetes (15826.08 ±8143.434pg/mL) than in nondiabetics (12534.06±6323.92pg/mL) with a p-value 0.02. When NT-pro BNP was compared there was no significant found difference between the non-diabetic group and the Controlled Diabetes-Group (p-value 0 .882), but it was significantly higher in the Uncontrolled Diabetes-Group (p-value<0.001). A moderate positive association was found between NT-pro BNP and glycosylated haemoglobin (r=0.541, p-value<0.001).
Conclusion: Although obesity has an inverse relation with plasma natriuretic peptides level and most patients with diabetes are overweight, the plasma NT-pro BNP is still a very informative tool and holds its significance as a diagnostic and prognosis marker in diabetic patients with heart failure.

Abstract
Objective: To determine the frequency of gestational diabetes mellitus in pregnant women reporting to a public sector tertiary care hospital and find the association of gestational diabetes mellitus with age.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: Pathology Department, Combined Military Hospital, Quetta Pakistan, from Jan 2016 to Mar2017.
Methodology: Five hundred and thirty pregnant women who reported to the Pathology Department of the hospital for an Oral Glucose Tolerance Test at 24-28 weeks of gestation were included. The blood samples were taken after ten hours off fasting and one hour and two hours after loading with 75g of anhydrous glucose and analyzed using the enzymatic (Glucose Oxidase) method. Gestational diabetes mellitus was diagnosed using guidelines recommended by the International Association for Diabetes and Pregnancy Study Group /American Diabetic Association for a one-step diagnosis of gestational diabetes mellitus according to the new criteria.
Results: The frequency of gestational diabetes mellitus was quite high 190(35.8%). Of these 530 pregnant women, 162(85.3%)women were diagnosed with Fasting Plasma Glucose, and 28 women were diagnosed with 1-hour or 2-hour after the glucose load test. Age-group of ≥ 30 years had the highest number of women with gestational diabetes mellitus.
Conclusion: The frequency of gestational diabetes mellitus in our hospital-reported sample of pregnant women was 35.8%,associated with advanced age. The maximum number of women were diagnosed as having gestational diabetes mellitus based on the fasting Plasma Glucose cut-off value.

Abstract
Heat shock transcription factors (HSF) are divided into classes A, B and C. Class A transcription factors are generally recognized as transcriptional activators, while functional characterization of class B and C heat shock transcription factors have not been fully developed in most plant species. We isolated and characterized a novel HSF transcription factor gene, TrHSFB2a (a class B HSF) gene, from the drought stress-sensitive forage crop species, white clover (Trifolium repens). TrHSFB2a was highly homologous to MtHSFB2b, CarHSFB2a, AtHSFB2b and AtHSFB2a. The expression of TrHSFB2a was strongly induced by drought (PEG6000 15% w/v), high temperature (35 °C) and salt stresses (200 mM L-1 NaCl) in white clover, while subcellular localization analysis showed that it is a nuclear protein. Overexpression of the white clover gene TrHSFB2a in Arabidopsis significantly reduced fresh and dry weight, relative water contents (RWC), maximum photosynthesis efficiency (Fv/Fm) and performance index on the absorption basis (PIABS), while it promoted leaf senescence, relative electrical conductivity (REC) and the contents of malondialdehyde (MDA) compared to a wild type under drought, heat and salt stress conditions of Arabidopsis plants. The silencing of its native homolog (AtHSFB2a) by RNA interference in Arabidopsis thaliana showed opposite trends by significantly increasing fresh and dry weights, RWC, maximum photosynthesis efficiency (Fv/Fm) and performance index on the absorption basis (PIABS) and reducing REC and MDA contents under drought, heat and salt stress conditions compared to wild type Arabidopsis plants. These phenotypic and physiological indicators suggested that the TrHSFB2a of white clover functions as a negative regulator of heat, salt and drought tolerance. The bioinformatics analysis showed that TrHSFB2a contained the core B3 repression domain (BRD) that has been reported as a repressor activator domain in other plant species that might repress the activation of the heat shock-inducible genes required in the stress tolerance process in plants. The present study explores one of the potential causes of drought and heat sensitivity in white clover that can be overcome to some extent by silencing the TrHSFB2a gene in white clover.

Abstract
Abstract
Background
The incidence and severity of ischemic heart disease (IHD) is exacerbated by coronary artery disease (CAD). Monocytes and macrophages are central to atherosclerosis. Endogenous small extracellular vesicles (sEVs) can shuttle microRNAs and other molecular cargos from cell to cell, mediating expressional and functional response in the recipient cells. Recent evidence supports a role for sEVs in modulating macrophage phenotype. The pericardial fluid (PF) is in direct contact with the epicardium and contain sEVs. We recently showed that human PF-sEVs are capable to modulate cardiovascular cells via microRNA shuttling.
Purpose
This study sought to investigate whether PF-sEVs regulate macrophages, contributing to a specific immunophenotype in CAD patients.
Methods
PF was collected from either CAD patients undergoing coronary bypass surgery (CABG) or non-atherosclerotic patients operated for mitral valve repair (non-CAD control group). sEVs were isolated using size exclusion chromatography and characterised for size (Nanosight tracking analysis; NTA), tetrasapanin content (by Nanoview chips), microRNA content by RNA seq and proteomic analysis. Monocytes from healthy donors were isolated from buffy coats and differentiated into macrophages following established protocols. Macrophages were incubated with either CAD-sEVs or non-CAD sEVs for 24h at 37oC. The cells were collected and processed for mRNA analyses (qRT-PCR) and flow cytometry. Human PF-cells were isolated and analysed to be compared with the in vitro setting. Further bioinformatics were employed to understand functional pathways and validated in PF from patients.
Results
Exposure to CAD-sEVs induces a proinflammatory profile of human macrophages. CAD-sEVs treated macrophages showed a CD36+low, CD206+low CD40+high profile. While non-CAD-sEVs did not statistically differ from PBS nor untouched groups, CAD-sEVs increased the mRNA level of IL1a, IL1b, TNFa and decreased MRC1. Proteomics revealed that PF-sEVs from CAD patients carried higher amounts of pro-inflammatory molecules (ICAM-1 and IL18) compared to NonCAD control. Bioinformatics analysis showed that 861 miRNAs were decreased in the PF-sEVs from CAD patients compared to non-CAD. miRNA targets prediction and pathway analyses reported that clusters of deregulated miRNAs could regulate CD36 and SRB1 which were shown to be decreased in CAD-sEVs treated macrophages. Human PF-cells revealed a reduced expression of CD36 on PF-macrophages.
Conclusions
We demonstrate, for the first time, that sEVs isolated from the PF of CAD patients induce a proinflammatory profile of human macrophages and that target crucial lipid metabolism pathways. These clinically relevant results could drive to decipher improved therapeutics able modulate the epicardial/myocardial immune response in CAD patients.

Abstract
Abstract
Background
Bicuspid aortic valve (BAV) patients develop ascending aortic (AAo) dilation. The pathogenesis of BAV-aortopathy (genetic vs. hemodynamic) remains unclear.
Purpose
To identify regional changes around the AAo wall in BAV patients with aortopathy integrating clinical imaging and molecular data.
Methods
BAV patients with aortopathy (n=20) were recruited prospectively to surgically collect aortic tissue and perform four-dimensional cardiac magnetic resonance (CMR) scans. Molecular markers were measured analysing the tissue biopsies (n=15) and wall shear stress (WSS) across the AAo circumference was calculated from the 4D CMR data (n=11 patients, and n=7 additional healthy volunteers for comparison). Dilated (anterior/right) vs. non-dilated (posterior/left) circumferential segments were profiled for whole genomic microRNAs (Next Generation RNA-Sequencing, miRCURY LNA PCR), proteins content (Tandem Mass Spectrometry) and elastin fragmentation and degeneration (histomorphometric analysis). Picture 1 summarises the study approach (including a map of the AAo divided in the following segments: A=anterior, AR=anterior-right, PR=posterior-right, P=posterior, PL=posterior-left, AL=anterior-left).
Results
Integrated bioinformatic analyses of RNA-sequencing and proteomic datasets identified 5 microRNAs (miR-128-3p, miR-210-3p, miR-150-5p, miR-199b-5p, and miR-21-5p) differentially expressed across the AAo circumference. Among them, three miRNAs (miR-128-3p, miR-150-5p, and miR-199b-5p) were predicted to have an effect on eight common target genes, whose expression was dysregulated according to proteomic analyses and involved in vascular endothelial growth factor signalling, hippo signaling and arachidonic acid pathway. Decreased elastic fibre levels and elastic layer thickness were observed in the dilated segments in the histomorphometric analysis. Increased WSS and flow-velocity, helical streamlines and asymmetrical flow were observed at the anterior/right wall in asymmetrically and symmetrically dilated patients (the latter exhibiting higher WSS), compared to healthy volunteers.
Conclusion
This study has newly revealed concomitant expressional dysregulation of miRNAs, proteins, and elastic fibres on the anterior/right wall in dilated BAV patients, corresponding to regions of elevated WSS, contributing to advance the understanding of the interplay of genetic and hemodynamic factors underpinning BAV aortopathy.

Abstract
Iodine complexes have known antimicrobial properties along with reported in-vitro antiviral activity for several viruses. Renessans is one such product with iodine complexes and ascorbic acid. The present study was designed to determine its efficacy for SARS-CoV-2 in Rhesus macaque. Rhesus macaque were assigned to: A) prophylactic group (n = 3), (B) treatment group (n = 3), (C) infection control group (n = 4), and (D) negative control group (n = 4). Groups A, B, and C were challenged with 2 × 106 TCID of SARS-CoV-2. The prophylactic group (A) was administered Renessans from 5 days before infection till 8 days postinfection (DPI). The treatment group (B) was administered Renessans from 3 till 8 DPI. Group C was administered water-insoluble fractions only. Nasal swabs from all monkeys of groups A, B, and C remained positive for SARS-CoV-2 till 2 and 7 DPI, while the swabs became negative for groups A and B at 14 DPI. Likewise, fecal matter of monkeys in group A returned negative results during the experiment, while that of group B had significantly decreased viral load (101.5 genome copies/mL) compared to group C (103 genome copies/mL). Hence, it is concluded that Renessans has in-vivo SARS-CoV-2 activity and may result in early clearance of SARS-CoV-2.

Abstract
Objective: To estimate the sero-positivity of SARS-CoV-2 in health care workers based on specific antibodies in a tertiary care hospital.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: Combined Military Hospital Kohat Pakistan, Jun to Jul 2020.
Methodology: 292 Health Care Workers from different departments were included by non-probability consecutive sampling. They were divided into three groups (High risk, Intermediate risk and low risk) according to the exposure risk to COVID-19 patients. In addition, serum samples for SARS- CoV-2 specific quantitative antibodies were collected. The odds ratio for SARSCoV-2 Ab risk was calculated for different risk groups and male and female health care workers.
Result: Out of 292 Health Care Workers, 243 (83.22%) were male, and 49 (16.78%) were female, with a mean age of 34.64 ± 7.25 years. SARS- CoV-2 specific Ab was detected in 43 (14.72%) individuals. The risk of sero-positivity was higher in the high-risk group than the intermediate-risk group (Odds ratio 1.171 vs 0.878) and higher in the intermediate-risk group than the low-risk group (odds ratio 1.120 vs 0.747). The risk was also higher in females than in males (Odds ratio 1.676 vs 0.878).
Conclusion: The sero-positivity of SARS-CoV-2 in healthcare workers in tertiary care hospitals is high. The results indicate that we must improve our local hygiene and protective standards.

Abstract
Heat shock protein 90 (Hsp90) plays an important role in plant developmental regulation and defensive reactions. Several plant species have been examined for the Hsp90 family gene. However, the Hsp90 gene family in cabbage has not been well investigated to date. In this study, we have been discovered 12 BoHsp90 genes in cabbage (Brassica oleracea var. capitata L.). These B. oleracea Hsp90 genes were classified into five groups based on phylogenetic analysis. Among the five groups, group one contains five Hsp90 genes, including BoHsp90-1, BoHsp90-2, BoHsp90-6, BoHsp90-10, and BoHsp90-12. Group two contains three Hsp90 genes, including BoHsp90-3, BoHsp90-4, and BoHsp90. Group three only includes one Hsp90 gene, including BoHsp90-9. Group four were consisting of three Hsp90 genes including BoHsp90-5, BoHsp90-7, and BoHsp90-8, and there is no Hsp90 gene from B. oleracea in the fifth group. Synteny analysis showed that a total of 12 BoHsp90 genes have a collinearity relationship with 5 Arabidopsis genes and 10 Brassica rapa genes. The promoter evaluation revealed that the promoters of B. oleracea Hsp90 genes included environmental stress-related and hormone-responsive cis-elements. RNA-seq data analysis indicates that tissue-specific expression of BoHsp90-9 and BoHsp90-5 were highly expressed in stems, leaves, silique, and flowers. Furthermore, the expression pattern of B. oleracea BoHsp90 exhibited that BoHsp90-2, BoHsp90-3, BoHsp90-7, BoHsp90-9, BoHsp90-10, and BoHsp90-11 were induced under cold stress, which indicates these Hsp90 genes perform a vital role in cold acclimation and supports in the continual of normal growth and development process. The cabbage Hsp90 gene family was found to be differentially expressed in response to cold stress, suggesting that these genes play an important role in cabbage growth and development under cold conditions.

Background
The incidence and severity of ischemic heart disease(IHD) is exacerbated by coronary artery disease (CAD). Monocytes and macrophages are central to atherosclerosis. Endogenous small extracellular vesicles(sEVs) can shuttle microRNAs and other molecular cargos from cell to cell, mediating expressional and functional response in the recipient cells. Recent evidence supports a role for sEVs in modulating macrophage phenotype. The pericardial fluid(PF) is in direct contact with the epicardium and contain sEVs. We recently showed that human PF-sEVs are capable to modulate cardiovascular cells via microRNA shuttling. Moreover, pericardial cells reportedly cross-talk with the myocardium to regulate immune response to IHD.
Purpose
This study sought to investigate whether PF-sEVs regulate macrophages, contributing to a specific immunophenotype in CAD patients.
Methods
PF was collected from either CAD patients undergoing coronary bypass surgery(CABG) or non-atherosclerotic patients operated for mitral valve repair(non-CAD control group).sEVs were isolated using size exclusion chromatography and characterised for size(Nanosight tracking analysis; NTA), tetrasapanin content(by Nanoview chips),microRNA content by RNA seq and proteomic analysis. Monocytes from healthy donors were isolated from buffy coats and differentiated into macrophages following established protocols. Macrophages were incubated with either CAD-sEVs or non-CAD sEVs for 24h at 37oC.The cells were collected and processed for mRNA analyses(qRT-PCR) and flow cytometry.Conditioned medium from sEVs treated macrophages was used to further analyse downstream effect on T cells.Further bioinformatics were employed to understand functional pathways and validated in PF from patients.
Results
Exposure to CAD-sEVs induces a proinflammatory profile of human macrophages.CAD-sEVs treated macrophages showed a CD36+low,CD206+low,CD40+high profile.While non-CAD-sEVs did not statistically differ from PBS nor untouched groups, CAD-sEVs increased the mRNA level of IL1a,IL1b,TNFa and decreased MRC1.Proteomics revealed that PF-sEVs from CAD patients carried higher amounts of pro-inflammatory molecules(ICAM-1 and IL18)compared to non-CAD control.Bioinformatics analysis showed that 861 miRNAs were decreased and 482 increased in the PF-sEVs from CAD patients compared to non-CAD.miRNA targets prediction and pathway analyses reported that clusters of deregulated miRNAs could regulate CD36 and SRB1 which were shown to be decreased in CAD-sEVs treated macrophages.In addition,media from CAD-sEVs treated macrophages induced a higher T cell activation profile.
Conclusions
We demonstrate, for the first time, that sEVs isolated from the PF of CAD patients induce a proinflammatory profile of human macrophages and that target crucial lipid metabolism pathways.These clinically relevant results could drive to decipher improved therapeutics able modulate the epicardial/myocardial immune response in CAD patients

Abstract
Background Type 2 Diabetes-related medication errors are frequently reported from the hospitals and consequently are of major concern. However, such reports are insufficient when developing healthcare settings are pursued in literature. Keeping this inadequacy in mind, we therefore aimed to explore physicians' perceptions, experiences and expectations of medication errors when managing patients with Type 2 Diabetes Mellitus. Methods A qualitative design was adopted. By using a semi-structured interview guide through the phenomenology-based approach, in-depth, face-to-face interviews were conducted. Physicians practicing at the medicine ward of Sandeman Provincial Hospital, Quetta, were purposively approached for the study. All interviews were audio-taped, transcribed verbatim, and were then analyzed for thematic contents by the standard content analysis framework. Results Although the saturation was reached at the 13th interview, we conducted additional two interviews to ensure the saturation. Fifteen physicians were interviewed, and thematic content analysis revealed six themes and nine subthemes. Mixed conceptualization and characterization of medication errors were identified. Medication errors were encountered by all physicians however poor understanding of the system, deficiency of logistics and materials were rated as barriers in reporting medication errors. Among contributors of medication errors, physicians themselves as well as dispensing and patient-related factors were identified. Physicians suggested targeted training sessions on medication error-related guidelines and reporting system. Parallel, establishment of an independent unit, involving the pharmacists, and strict supervision of paramedics to minimize medication errors was also acknowledged during data analysis. Conclusion With a longer life expectancy and a trend of growing population, the incidences of medication errors are also expected to increase. Our study highlighted prescribing, dispensing and administration phases as contributing factors of medication errors. Although, physicians had poor understanding of medication errors and reporting system, they believed getting insights on guidelines and reporting system is essential. A review of admission and discharge reconciliation must be prioritized and a culture of teamwork, communication and learning from mistakes is needed.

Abstract
Hydrodehalogenation is an effective strategy for transforming persistent and potentially toxic organohalides into their more benign congeners. Common methods utilize Pd/C or Raney-nickel as catalysts, which are either expensive or have safety concerns. In this study, a nickel-based catalyst supported on titania (Ni-phen@TiO2 -800) is used as a safe alternative to pyrophoric Raney-nickel. The catalyst is prepared in a straightforward fashion by deposition of nickel(II)/1,10-phenanthroline on titania, followed by pyrolysis. The catalytic material, which was characterized by SEM, TEM, XRD, and XPS, consists of nickel nanoparticles covered with N-doped carbon layers. By using design of experiments (DoE), this nanostructured catalyst is found to be proficient for the facile and selective hydrodehalogenation of a diverse range of substrates bearing C-I, C-Br, or C-Cl bonds (>30 examples). The practicality of this catalyst system is demonstrated by the dehalogenation of environmentally hazardous and polyhalogenated substrates atrazine, tetrabromobisphenol A, tetrachlorobenzene, and a polybrominated diphenyl ether (PBDE).

Abstract
Abstract
Aim
While surgeons and robotic companies are key stakeholders involved in the adoption of Robotic Surgery (RS), the public's role is often overlooked. However, given that patients hold ultimate power over their healthcare decisions, public acceptance of RS is crucial. This study aims to identify public understanding, opinions and misconceptions on RS and present solutions to facilitate its wider integration.
Method
An online questionnaire distributed via social media platforms between February and May 2021 identified the views of UK adults on RS. The data was evaluated using thematic analysis, descriptive statistics, and statistical analysis. Statistical differences in age, gender, education level, and presence in the medical field were also sought.
Results
263 responses were obtained, with 216 (82.1%) analysed. Demographic differences provided significantly different results. Participants were relatively uninformed about RS, with a median knowledge score of 4.00(2.00–6.00) on a 10-point likert scale. Fears surrounding increased risk, reduced precision and technological failure were identified, alongside misconceptions on what RS entails, including it being autonomous. However, providing factual information in the survey about RS statistically increased participant comfort (p=<0.0001). Most (61.8%) participants believed robot manufacturers were responsible for malfunctions, but doctors were held accountable more by older, less educated, and non-medical participants.
Conclusions
This study highlights the role of negative and inaccurate public perceptions surrounding RS in impeding its widespread adoption. Greater emphasis must be placed on patient education in RS to mitigate misconceptions and ensure greater diffusion of its benefits

Abstract
Objective: To determine extended-spectrum beta-lactamase (ESBL) producing, multidrug-resistant (MDR) uropathogens and their antimicrobial susceptibility profile in various age groups and gender.
Study Design: Comparative cross sectional study.
Place and Duration of Study: Department of Pathology, Combined Military Hospital Abbottabad, from Jan to Dec 2018.
Methodology: A total of 727 urine samples were collected and inoculated on cysteine lactose electrolyte deficient (CLED) agar plates (Oxoid). Plates were incubated for 24-48 hours at 37°C ±2 aerobically. Growth was identified by standard techniques. Antimicrobial susceptibility was determined.
Results: The rate of positive culture was 19%. Uropathogens spectrum showed that there were Escherichia coli 82 (59.85%), Klebsiella pneumoniae 37 (27.01%), Serratia spp. 4 (2.92%), Enterobacter spp. 4 (2.92%), Citrobacter spp. 3 (2.19%), Pseudomonas aeruginosa 2 (1.46%), Staphylococcus saprophyticus 3 (2.19%) and Enterococcus spp. 2 (1.46%). Susceptibility was as follows: Ampicillin (2.92%), Co-amoxiclav (26.28%), Ceftriaxone (64.69%), Cefepime (58.39%), Tazobactum-piperacillin (63.50%), Imipenem (82 %), Ciprofloxacin (27.01%), Co-trimoxazole (29.93%), Amikacin (74.45%), Nitrofurantoin (81.75%) and SulbactumCefoperazone (54.48%). Among 130 Gram negative bacilli (GNB) from urinary isolates 71(54.6%) were ESBL producer and 59 (44.3%) were non-ESBL producers. No isolate of Serratia spp, Enterobacter spp. and Citrobacter spp. Were producing ESBL. Out of130, Gram negative bacilli 92 (70.8%) were MDR and 38 (29.2%) were non-MDR.
Conclusion: Extended-spectrum beta-lactamase production and MDR is significantly high in uropathogens. Empirical treatment followed by a de-escalation of antimicrobial is suggested after culture report in order to combat the problem of emerging antibiotic resistance.Keywords: ,

Abstract
Abstract
Introduction
As an increasing number of specialties have begun to adopt robotic surgery (RS), its prevalence within the NHS is continually rising. This study aims to establish stakeholders’ opinions on the opportunities and challenges of the widespread adoption of RS.
Method
Participants were recruited through social media platforms such as LinkedIn or via university affiliations and current RS research. Semi-structured interviews of eight surgeons and five company representatives were conducted online. Transcripts were analysed to formulate themes surrounding the opportunities and challenges of RS.
Results
This study identified six common themes amongst shareholders: Perspective, Ethics, Impact of Robotics, Training, Adoption and Finances. The success rates and quality of results offered by RS make it a recognised future surgical staple amongst interviewees. However, the technology remains a contentious subject amongst surgeons, with many doubting whether the benefits outweigh the costs associated with implementation. Such reservations are further exacerbated by the absence of a formal training pathway. National guidelines are necessary to embed RS within the NHS infrastructure, allowing greater standardisation for patients and surgeons. The importance of patient education to address misconceptions was emphasised. Despite current high costs, robotic technology is forecasted to become cheaper with greater use and increased market competition. Interviewees stressed that responsibility for errors lies with the surgeon, but with the manufacturer for instrument malfunctions.
Conclusions
This study highlights stakeholders’ views on the opportunities and challenges of RS. The identified themes should form the basis of the proposed recommendations to facilitate a more widespread adoption of RS.

Abstract
Insects change their stimulus-response through the perception of associating these stimuli with important survival events such as rewards, threats, and mates. Insects develop strong associations and relate them to their experiences through several behavioral procedures. Among the insects, Apis species, Apis mellifera ligustica are known for their outstanding ability to learn with tremendous economic importance. Apis mellifera ligustica has a strong cognitive ability and promising model species for investigating the neurobiological basis of remarkable olfactory learning abilities. Here we evaluated the olfactory learning ability of A. mellifera by using the proboscis extension reflex (PER) protocol. The brains of the learner and failed-learner bees were examined for comparative transcriptome analysis by RNA-Seq to explain the difference in the learning capacity. In this study, we used an appetitive olfactory learning paradigm in the same age of A. mellifera bees to examine the differential gene expression in the brain of the learner and failed-learner. Bees that respond in 2nd and 3rd trials or only responded to 3rd trials were defined as learned bees, failed-learner individuals were those bees that did not respond in all learning trials The results indicate that the learning ability of learner bees was significantly higher than failed-learner bees for 12 days. We obtained approximately 46.7 and 46.4 million clean reads from the learner bees failed-learner bees, respectively. Gene expression profile between learners’ bees and failed-learners bees identified 74 differentially expressed genes, 57 genes up-regulated in the brains of learners and 17 genes were down-regulated in the brains of the bees that fail to learn. The qRT-PCR validated the differently expressed genes. Transcriptome analyses revealed that specific genes in learner and failed-learner bees either down-regulated or up-regulated play a crucial role in brain development and learning behavior. Our finding suggests that down-regulated genes of the brain involved in the integumentary system, storage proteins, brain development, sensory processing, and neurodegenerative disorder may result in reduced olfactory discrimination and olfactory sensitivity in failed-learner bees. This study aims to contribute to a better understanding of the olfactory learning behavior and gene expression information, which opens the door for understanding of the molecular mechanism of olfactory learning behavior in honeybees.

Introduction
Rheumatic mitral valve stenosis (MS) causes progressive left atrial (LA) fibrosis and functional impairment, pulmonary artery systolic hypertension and right ventricular (RV) dysfunction.
Purpose
The aim of the study was the evaluate the different characteristics between high gradients (HG) and low gradient (LG) MS and, within the LG group those with high (LG-HF) or low flow (LG-LF). Moreover, we wanted to evaluate if there was any difference in overall complications and atrial fibrillation (AF) incidence.
Methods
A total of 147 patients with isolated severe MS were retrospectively enrolled from the institutional echo database. Echocardiograms were read offline and clinical information were obtained from patients` records. Patients were divided into a group with HG (31 patients, mean MS gradient > 10 mmHg) and LG (116 patients, mean MS gradient ≤ 10 mmHg). The group of LG was then divided in low flow (Stroke volume index (SVi) ≤ 35 ml/m2, LF-LG: 68 patients) and in high flow (SVi > 35 ml/m2, HF-LG: 48 patients).
Results
The HG group was younger, although the difference did not reach statistical significance, higher percent of males (45% M vs 22% F, p = 0.02), higher heart rate (HR), left atrial volume, higher tricuspid regurgitation velocity (TVR) and derived pulmonary artery systolic pressure (PASP), RV fractional area changes (RV FAC) but similar RV longitudinal contraction. Moreover, the HG group had more severe MS calculated according to PHT. The group of LG was divided according to SVi: LF-LG group compare to HG-MS had higher percent of females (45% F vs 13% M, p < 0.001), similar AF (43% vs 32%, p = ns) and pre surgical complications (19% vs 16%, p = ns). LF-LG group had smaller LA systolic volume (117 ± 51 51 ml vs 148.6 ± 38 ml, p < 0.0001), lower LV-S` (5.3 ± 1.4 vs 6 ± 1.6 cm/s, p = 0.004), lower TRV (2.47 ± 0.5 vs 3.24 ± 0.7 m/s, p < 0.0001), higher TAPSE/PASP (0.64 ± 0.3 vs 0.45 ± 0.29, p < 0.001), lower RV S` (9.79 ± 2.01m/s vs 11.25 ± 3.1 m/s, p = 0.01), higher RVFAC (38.5 ± 9.6% vs 30.9 ± 9.2%, p = 0.0005). The group of LG-LF had also less severe MS (1.3 ± 0.6 cm2 vs 1.15 ± 0.3 cm2, p < 0.01).
Conclusion
Patients with HG MS were those with worst left ventricular involvement, higher PASP and lower RV function. The LF-LG MS were older, and more females were included and even though they had smaller LA, lower values of PASP they had significantly higher percent of AF and similar pre surgical complications. It could be speculated that LF-LG severe MS patients could be a different phenotype of the disease.

Background
Stuck valve is a very rare and severe complication that occurs in mechanical valve replacement patients with ineffective anticoagulation. However, with COVID-19 restriction measures, it became challenging to regularly assess INR to make sure it falls within the target therapeutic range to prevent this complication.
Purpose
We wanted to explore how did the COVID-19 pandemic restrictions impacted mechanical valve replacement patients on chronic anticoagulation and the long-term consequences of limiting their access to health service.
Methods
We present a series of 10 patients on warfarin anticoagulation therapy who either underwent transthoracic echocardiography for a suspected stuck valve or were seen at the outpatient valve clinic with the residual consequences of a stuck valve during the COVID-19 restriction measures in our institute.
Results
Eight patients were female, two of whom were pregnant at the first trimester and eventually went on to receive an abortion; six patients received urgent valve replacement cardiac surgery; four patients were managed medically e.g. with heparin; none had thrombolytic therapy. Stuck prosthetic valves incident has increased significantly during this period, particularly those in the mitral position for which urgent replacement and prolonged hospitalization including intensive care admission, with high in-hospital mortality rates and high costs were necessary. Mean hospital admission time was 27.5 ± 18.5 days. The cost of treatment, as average estimated reimbursement, was 11,000 USD for medical admission only, and 43,200 USD when surgery was required, up to 64,000 USD when ECMO was part of patient management.
Conclusion
Despite governments’ efforts to implement telemedicine and virtual clinics, COVID-19 restrictions and health-messaging affected the routine follow-up of non-COVID-19 patients. We report dramatic consequences to this drastic change in healthcare: clinical complications, lost lives and inflated healthcare costs in patients with a prosthetic valve. We believe that non-COVID-19 patients have paid, and will continue to pay in the future, a price that is much greater than those patients who have suffered from COVID-19. Active engagement of patients should be implemented in a time of emergencies, and further studies should address the efficacy and cost-effectiveness of public policies aimed to decrease the burden of avoidable complications and missed diagnoses.

Abstract
Mytilin is one of the most important CS-αβ peptides involved in innate immune response in Mytilidae. In this study, we successfully identified four mytilin-like antimicrobial peptides (pernalins) from Asian green mussel Perna viridis by aligning the P. viridis transcriptome with 186 mytilins and myticins related sequences collected from the transcriptome data of six Mytilus species. Analysis on gene structure showed that pernalin genes had high conservation with mytilin B of Mediterranean mussel Mytilus galloprovincialis. Interestingly, all pernalin genes have a similar tissue expression feature, evidenced by the highest transcription level observed in the hemocytes and followed by the mantle. The lowest transcription level was observed in the foot and gills. qRT-PCR analysis showed that all pernalin genes were significantly down-regulated at each time points from 3 h to 48 h after Vibrio parahaemolyticus infection, suggesting their timely immune responses after bacterial infection.

Abstract
Climate change could be an existential threat to many crops. Drought and heat stress are becoming harder for cultivated crops. Cotton in Pakistan is grown under natural high temperature and low moisture, could be used as a source of heat and drought tolerance. Therefore, the study was conducted to morphological, physiological and molecular characterization of cotton genotypes under field conditions. A total of 25 cotton genotypes were selected from the gene pool of Pakistan based on tolerance to heat and drought stress. In field trail, the stress related traits like boll retention percentage, plant height, number of nodes and inter-nodal distance were recorded. In physiological assessment, traits such as photosynthesis rate, stomatal conductance, transpiration rate, leaf temperature, relative water content and excised leaf water loss were observed. At molecular level, a set of 19 important transcription factors, controlling drought/heat stress tolerance (HSPCB, GHSP26, HSFA2, HSP101, HSP3, DREB1A, DREB2A, TPS, GhNAC2, GbMYB5, GhWRKY41, GhMKK3, GhMPK17, GhMKK1, GhMPK2, APX1, HSC70, ANNAT8, and GhPP2A1) were analyzed from all genotypes. Data analyses depicted that boll retention percentage, photosynthesis, stomatal conductance, relative water content under the stress conditions were associated with the presence of important drought & heat TF/genes which depicts high genetic potential of Pakistani cotton varieties against abiotic stress. The variety MNH-886 appeared in medium plant height, high boll retention percentage, high relative water content, photosynthesis rate, stomatal conductance, transpiration rate and with maximum number transcription factors under study. The variety may be used as source material for heat and drought tolerant cotton breeding. The results of this study may be useful for the cotton breeders to develop genotype adoptable to environmental stresses under climate change scenario.

Abstract
Crop production is a serious challenge to provide food for the 10 billion individuals forecasted to live across the globe in 2050. The scientists' emphasize establishing an equilibrium among diversity and quality of crops by enhancing yield to fulfill the increasing demand for food supply sustainably. The exploitation of genetic resources using genomics and metabolomics strategies can help generate resilient plants against stressors in the future. The innovation of the next-generation sequencing (NGS) strategies laid the foundation to unveil various plants' genetic potential and help us to understand the domestication process to unmask the genetic potential among wild-type plants to utilize for crop improvement. Nowadays, NGS is generating massive genomic resources using wild-type and domesticated plants grown under normal and harsh environments to explore the stress regulatory factors and determine the key metabolites. Improved food nutritional value is also the key to eradicating malnutrition problems around the globe, which could be attained by employing the knowledge gained through NGS and metabolomics to achieve suitability in crop yield. Advanced technologies can further enhance our understanding in defining the strategy to obtain a specific phenotype of a crop. Integration among bioinformatic tools and molecular techniques, such as marker-assisted, QTLs mapping, creation of reference genome, de novo genome assembly, pan- and/or super-pan-genomes, etc., will boost breeding programs. The current article provides sequential progress in NGS technologies, a broad application of NGS, enhancement of genetic manipulation resources, and understanding the crop response to stress by producing plant metabolites. The NGS and metabolomics utilization in generating stress-tolerant plants/crops without deteriorating a natural ecosystem is considered a sustainable way to improve agriculture production. This highlighted knowledge also provides useful research that explores the suitable resources for agriculture sustainability.

Abstract
Background Hepatitis B Virus (HBV) is one of the most common human infectious agents, and the mutations in its genome may cause chronic hepatitis (CH), liver cirrhosis (LC), and hepatocellular carcinoma (HCC). This study was designed to characterize the enhancer-II (Enh-II) region of X gene in HBV positive patients to assess the association of such mutations with CH, LC, and HCC. Methods HBV positive samples (N = 200) with patients’ demographic and clinical data were collected from different regions of Khyber Pakhtunkhwa (KP), Pakistan. The Enh-II region of the HBx gene was sequenced and zanalyzed for polymorphism associated with advanced liver disease. Univariate and logistic regression analyses were performed to evaluate potent mutations associated with a risk for LC and HCC. Results HBV Enh-II region sequences analysis revealed 25 different mutations. The highest frequency of mutations S101F (62.2%), A102V/R/G/I (56.25%), M103L/A (68.75%)were found in HCC, followed in LC and CH patients as 57.1%, 42.8%, 28.52% 16%, 15.2% and 18.4% respectively. H94 deletion in the α-box of the Enh-II region, associated with a high risk of HCC was found in half of the HCC patients. This deletion was present in 28.5% of LC and 6.5% of CH patients. Importantly, the high frequency of some notable mutations such as E109A/Y, A110S/K, Y111D/E, and F112L was first time reported in the entire study population. The frequencies of these mutations were high in HCC (43.75%, 37.5%, 50% and 43.75% respectively) as compared to LC (14.28%, 14.28%, 28.2% and 42.8%) and CH patients (12.8%, 15.2%, 16.8% and 16% respectively). Conclusion Mutations associated with LC and HCC are prevalent in the Enh-II region in Pakistani HBV isolates. The mutations found are alarming in CH patients as these may progress to LC and HCC in a large number of patients.

Abstract
Plant and fruit surfaces are covered with cuticle wax and provide a protective barrier against biotic and abiotic stresses. Cuticle wax consists of very-long-chain fatty acids (VLCFAs) and their derivatives. β-Ketoacyl-CoA synthase (KCS) is a key enzyme in the synthesis of VLCFAs and provides a precursor for the synthesis of cuticle wax, but the KCS gene family was yet to be reported in the passion fruit (Passiflora edulis). In this study, thirty-two KCS genes were identified in the passion fruit genome and phylogenetically grouped as KCS1-like, FAE1-like, FDH-like, and CER6-like. Furthermore, thirty-one PeKCS genes were positioned on seven chromosomes, while one PeKCS was localized to the unassembled genomic scaffold. The cis-element analysis provides insight into the possible role of PeKCS genes in phytohormones and stress responses. Syntenic analysis revealed that gene duplication played a crucial role in the expansion of the PeKCS gene family and underwent a strong purifying selection. All PeKCS proteins shared similar 3D structures, and a protein-protein interaction network was predicted with known Arabidopsis proteins. There were twenty putative ped-miRNAs which were also predicted that belong to nine families targeting thirteen PeKCS genes. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation results were highly associated with fatty acid synthase and elongase activity, lipid metabolism, stress responses, and plant-pathogen interaction. The highly enriched transcription factors (TFs) including ERF, MYB, Dof, C2H2, TCP, LBD, NAC, and bHLH were predicted in PeKCS genes. qRT-PCR expression analysis revealed that most PeKCS genes were highly upregulated in leaves including PeKCS2, PeKCS4, PeKCS8, PeKCS13, and PeKCS9 but not in stem and roots tissues under drought stress conditions compared with controls. Notably, most PeKCS genes were upregulated at 9th dpi under Fusarium kyushuense biotic stress condition compared to controls. This study provides a basis for further understanding the functions of KCS genes, improving wax and VLCFA biosynthesis, and improvement of passion fruit resistance.
