Abstract
Abstract Due to extensive application of antibiotics as growth promoters in animal feed, antimicrobial resistance has been increased. To overcome this challenge, rumen microbiologists search for new probiotics to improve the rate of livestock production. The present study was aimed to isolate and evaluate breed-specific lactic acid bacteria (LAB) as potential animal probiotics. The current study was conducted during 10 months from July 2020 to April 2021, in which a total of n=12 strains were isolated from different samples including milk, rumen, and feces of Nilli Ravi Buffaloes. These isolates were evaluated for their antimicrobial potential against common animal pathogens (Bacillus spp., E. coli, Staphylococcus aureus, Salmonella spp., Listeria spp.). All the isolates were identified using 16S rRNA gene sequencing and the phylogenetic analyses inferred that these strains showed close relations to the species of various genera; Enterococcus lactis, Pediococcus pentosaceus, Bacillus subtilis Weissella cibaria, Weissella soli, Bacillus tequilensis, Weissella bombi, Bacillus licheniformis, Lactococcus lactis, Bacillus megaterium, Lactobacillus ruminis, and Lactococcus lactis. NMCC-Ru2 has exhibited the enormous potential of antimicrobial activity, 28 mm, for Salmonella typhimurium;23 mm for Listeria monocytogenes 21 mm for E.coil. Highest resistance was seen in NMCC-Ru2 agasint test antbiotic, like 25.5 mm for Tetracycline. Overall results revesl that the probiotic profile of isolates was achieved using standard criteria, particularly with animal probiotic properties

Abstract
The emergence of medication resistance and unfavorable side effects from existing antibiotics has prompted the quest for novel antimicrobial agents over the last 2 decades. Plant extracts have been shown to have antibacterial effects in numerous studies. The objective of this study was the evaluation of the antibacterial effect of economically important medicinal plants found in Pakistan. Onosma bracteatum (flowers and leaves), Viola odorata (flowers and leaves), Cuscuta reflexa (whole plant), Swertia chirata (whole plant), and Fagonia arabica (whole plant) were used against Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa. Water and ethanol extracts were obtained from different parts of the plants. To evaluate the antibacterial effect of these plants, qualitative assay agar well diffusion method was performed. The minimum inhibitory concentration (MIC) was determined by the broth micro dilution method. Results revealed that the highest inhibition zone (18 mm) was shown by ethanol extract of V odorata flower against P aeruginosa. Ethanol extract of C reflexa plants is best for all 3 tested microbes (P aeruginosa, B subtilis, and E coli). The results concluded that all these plants have abilities to fight against these tested bacteria. Ethanol extract of V odorata flower has the highest activity against P aeruginosa.

Abstract
Fusarium cotton wilt is a devastating disease of the cotton crop throughout the world, caused by Fusarium oxysporum f.sp. vasinfectum (FOV). Chemical control has many side effects, so, biological controls have been widely used for the management of Fusarium wilt. This study aimed to investigate the possible use of an actinomycetes Saccharothrix algeriensis (SA) NRRL B-24137 to control FOV. To access in-vitro anti-Fusarium ability of SA NRRL B-24137, dual culture assay, spore germination and seed germination tests were carried out. Following in-vitro investigations, several pot tests in a greenhouse environment were used to evaluate the biological control potential of SA NRRL B-24137 against FOV. Dual culture assay and spore germination revealed that SA NRRL B-24137 showed significant anti-Fusarium activity.During spore germination 87.77% inhibition of spore germination were observed. In pot experiments, SA NRRL B-24137 primed cotton seeds resulted in a 74.0% reduction in disease incidence. In soil there was a significant reduction in FOV spores in the presence of SA NRRL B-24137. Positive correlation was also observed on different concentrations of SA NRRL B-24137 towards FOV reduction. The results of this study showed that SA NRRL B-24137 has the potential to be employed as a biocontrol agent against Fusarium cotton wilt, improving cotton growth characteristics and yield.

Abstract
Emergence of plasmid mediated colistin and extended spectrum β-lactamases (ESBL) resistant genes has been impacted the efficacy of colistin and β-lactams drugs like 3rd, 4th generation cephalosporin. Current study was aimed to investigate antimicrobial resistance genes (ARGs) among Escherichia coli isolates from meat producing commercial broilers in Pakistan. Two hundred (n=200) fecal samples were collected during January-2018 to August-2019. For isolation of E. coli, pink colonies on MacConkey agar were transferred to EMB agar. Metallic sheen color colonies were tested biochemically using API-20E kit. The molecular identification of E. coli (n=153) was targeted by amplification of uid gene through polymerase chain reaction (PCR) and different ARGs i.e. gentamicin, streptomycin, tetracycline, colistin, β-lactams drugs, quinolone and ampicillin followed by sequence analysis. Genotypically, followed by phenotypically of resistant ARGs of isolated PCR-confirmed E. coli (153) shoed resistant against gentamicin (aac(3)-IV), streptomycin (aadA1), tetracycline (tetA), colistine (mcr-1), ampicillin (bla-TEM) and bla-CTX-M were 86%, 88%, 86%, 88%, 83% & 77% respectively. 33/38 (86%) of the isolate was positive for quinolone resistance. Colistine (mcr-1), ESBLs (bla-TEM) and (bla-CTX-M) resistance genes were 88%, 83% and 77% respectively. About 33 isolated E. coli harbored the both mcr-1 and ESBLs genes. All of E. coli isolates were found sensitive to ceftriaxone (CTX-30) and imipenem (IMP-10). The Isolated E. coli showed single or multi clade decadency. The E. coli and ARGs sequences showed single or multi clade decadency. This is first comprehensive study from Pakistan that described the molecular evidences of ARGs and their co-existence in single isolates originated from commercial poultry. Commercial chicken (Broilers) can act as melting pot of antibiotic resistance genes for human being. It is alarming situation for surveillance of antibiotic resistance program because of more regulated prescription of antimicrobial agents in Pakistan.

Abstract
Background The therapeutic potential of Haloxylon griffithii found in northern region of Balochistan, so far has been neglected. Purpose The current study was aimed to assess the phytochemicals and pharmacological potential of fractions isolated from H griffithii. Research Design During phytochemicals analysis of H griffithii using GC/MS showed various bioactive compounds like alkaloids, flavonoids, terpenoids, tannins, saponins, and carboxylic acids. In vitro antioxidant activity of H griffithii was determined by 2, 2'- diphenyl-1-picrylhydrazyl (DPPH) assay. Disc diffusion method was used to evaluate the antimicrobial activity. Results The quantitative analysis of ethyl acetate showed highest total flavonoid contents (1.19 ± .05) while ethanol with lowest value (.52 ± .01). The total phenolic contents in ethyle acetate was 1.50 ± .42, whereas ethanol showed lowest value (.77 ± .02). Ethanol exhibited excellent (88.68 ± 3.0) free radical scavenging potential measured by 1,1-diphenyl-2-picryl-hydrazyl radical scavenging assay. For antimicrobial activity, different bacterial and fungal strains like B subtilis, S aureus, E coli, S typhi, C albicans, and A. niger were selected. The essential oil showed maximum % inhibition diameter (9 mm) against B. Subtillus and (5 mm) against C albicans, respectively. The ethyl acetate presented % inhibition diameter (9 mm) against S aureus and (6 mm) against A niger. Anti-urease activity also showed positive response. Conclusions The presence of high (%) bioactive compounds with great therapeutic potential suggest that H griffithii can be used as natural alternative of synthetic drugs without side effects.

Abstract
Industrial waste is mainly responsible for accumulating Zn (II) in the soil, which needs to be removed to avoid its bioaccumulation and hazardous effects on the environment. In a recent study, the potential of the RY12 strain was evaluated as a biosorbent of Zn (II) ions in an aqueous medium. Different microbiological techniques like biochemical, molecular characterization, and 16S rRNA gene sequencing were used for the identification of RY12. The impact of different parameters such as the initial zinc ion concentration, pH, temperature, and the removal of other metals such as manganese, lead, cobalt, silver, copper, mercury, and chromium was also evaluated on the reduction of Zn (II). Fourier Transform Infrared spectroscopy (FTIR) was also carried out to investigate the role of cellular surfaces in the sorption of Zn+2 ions. Both biochemical and phylogenetic analyses established that strain RY12 Pseudomonas sp. capable of reducing Zn+2 up to 89% at 28°C (pH = 6.5; initial Zn+2 concentration = 200 mg/L). The FTIR analysis revealed that the bacterial cell wall’s amino, carboxyl, and phosphate groups were involved in the reaction with Zn (II). Our findings suggest that Pseudomonas sp. RY12 is a proficient bacterium for removing zinc from industrial waste and could be a valuable bioremediation agent.

Abstract
Background In the field of nanotechnology, the metallic nanoparticles are of remarkable interest because of their unique electronic, magnetic, chemical, and mechanical properties. Purpose: In the present work, silver nanoparticles (AgNPs) were synthesized using bio-reduction method. Research Design: Silver nitrate was used as metallic precursor and the extract of Moringa oleifera leaves with different concentrations was used as reducing as well capping agent. The extract exhibited strong potential in rapid reduction of silver ions for the synthesis of silver nanoparticles. The synthesized silver nanoparticles were characterized by UV-visible spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) techniques. Results: The absorption SPR peaks appeared in the range of 415 to 439 nm. SEM analysis exhibited that particles were spherical in shape with size distribution range from 10 nm to 25 nm. The synthesized silver nanoparticles were pure crystalline in nature as confirmed by the XRD spectra with average crystallite size 7 nm. In vitro antibacterial activity of the prepared silver nanoparticles colloidal samples as well the extract was studied using different concentrations of AgNPs (C1 = 100 μg/ml, C2 = 50 μg/ml, C3 = 25 μg/ml) by well diffusion method against Gram negative Escherichia coli. The antibacterial performance was assessed by measuring the zone of inhibition (ZOI). Conclusions The results suggested that AgNPs prepared by green approach can be considered as an alternative antibacterial agent.

Abstract
BACKGROUND Defects in methylenetetrahydrofolate dehydrogenase 1-like (MTHFD1L) expression have earlier been examined in only a few human cancers. OBJECTIVES Multi-omics profiling of MTHFD1L as a shared biomarker in distinct subtypes of human cancers. METHODS In the current study, for the multi-omics analysis of MTHFD1L in 24 major subtypes of human cancers, a comprehensive in silico approach was adopted to mine different open access online databases including UALCAN, Kaplan-Meier (KM) plotter, LOGpc, GEPIA, Human Protein Atlas (HPA), Gene Expression across Normal and Tumor tissue (GENT2), MEXPRESS, cBioportal, STRING, DAVID, TIMER, and Comparative Toxicogenomics Database (CTD). RESULTS We noticed that the expression of MTHFD1L was significantly higher in all the analyzed 24 subtypes of human cancers as compared with the normal controls. Moreover, MTHDF1L overexpression was also found to be significantly associated with the reduced overall survival (OS) duration of Bladder urothelial cancer (BLCA), Head and neck cancer (HNSC), Kidney renal papillary cell carcinoma (KIRP), Lung adenocarcinoma (LUAD), and Uterine corpus endometrial carcinoma (UCEC). This implies that MTHFD1L plays a significant role in the development and progression of these cancers. We further noticed that MTHFD1L was also overexpressed in BLCA, HNSC, KIRP, LUAD, and UCEC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of MTHFD1L-associated genes in five diverse pathways. We also explored few interesting correlations between MTHFD1L expression and its promoter methylation, genetic alterations, CNVs, and between CD8+ T immune cells level. CONCLUSION In conclusion, our results elucidated that MTHFD1L can serve as a shared diagnostic and prognostic biomarker in BLCA, HNSC, KIRP, LUAD, and UCEC patients of different clinicopathological features.

Abstract
BACKGROUND The association between human papillomavirus (HPV) and human breast cancer (BC) has already been thoroughly studied worldwide with contradictory findings. Although the researchers have tried to minimize the conflict using statistical meta-analysis, because of its shortcomings, there is still a need to evaluate the correlation between HPV and BC using any additional method. OBJECTIVES This study was launched to investigate the correlation between HPV and BC through the application of Bradford Hill criteria postulates. METHODS Population-wide studies associating HPV with BC were searched using the PubMed database. Then, the information of HPV burden in BC, normal/benign samples was analyzed, and ultimately Bradford Hill criteria postulates were applied on the collected evidence to explore the relationship between HPV and BC. In addition, to make the outcomes more authentic, we also reviewed the methodologies of previous studies to address the propensity of false results. RESULTS After a careful evaluation of the obtained data against major Bradford Hill criteria postulates, it was noted that all these postulates including strength, consistency, biological gradient, temporality, plausibility, experiment, specificity, and analogy were not fulfilled. CONCLUSION The results of the present study have failed to establish a casual association between HPV and BC rather suggested HPV as a cause-effective agent or at least a co-participant in the pathogenesis of BC. The weakness of association especially the low level of consistency across studies, and the lack of specificity of effect, there is a need for more experiments concerning Bradford Hill criteria postulates.

Abstract
Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help to establish it as a potential shared diagnostic and prognostic biomarker of different cancer subtypes. The GINS1 mRNA, protein expression, and promoter methylation were analyzed using UALCAN and Human Protein Atlas (HPA), while mRNA expression was further validated via GENT2. The potential prognostic values of GINS1 were evaluated through KM plotter. Then, cBioPortal was utilized to examine the GINS1-related genetic mutations and copy number variations (CNVs), while pathway enrichment analysis was performed using DAVID. Moreover, a correlational analysis between GINS1 expression and CD8+ T immune cells and a the construction of gene-drug interaction network was performed using TIMER, CDT, and Cytoscape. The GINS1 was found down-regulated in a single subtypes of human cancer while commonly up-regulated in 23 different other subtypes. The up-regulation of GINS1 was significantly correlated with the poor overall survival (OS) of Liver Hepatocellular Carcinoma (LIHC), Lung Adenocarcinoma (LUAD), and Kidney renal clear cell carcinoma (KIRC). The GINS1 was also found up-regulated in LIHC, LUAD, and KIRC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of GINS1 in two diverse pathways, while few interesting correlations were also documented between GINS1 expression and its promoter methylation level, CD8+ T immune cells level, and CNVs. Moreover, we also predicted few drugs that could be used in the treatment of LIHC, LUAD, and KIRC by regulating the GINS1 expression. The expression profiling of GINS1 in the current study has suggested it a novel shared diagnostic and prognostic biomarker of LIHC, LUAD, and KIRC.

Abstract
Introduction Cancer is one of the most common malignancies and the leading cause of death worldwide. As a member of the transmembrane emp24 domain (Tmed)/p24 family of proteins, TMED2 expression variations have been documented earlier in only a few subtypes of human cancers, and the multi-omics profiling of TMED2 as a shared biomarker in different other subtypes of human cancers remains to be uncovered. Methods In the current study, TMED2 multi-omics analysis in 24 major subtypes of human cancer was performed using different authentic online databases and bioinformatics analysis including UALCAN, Kaplan–Meier (KM) plotter, Human Protein Atlas (HPA), GENT2, MEXPRESS, cBioportal, STRING, DAVID, TIMER, and CTD. Results In general, the TMED2 expression in 24 major subtypes of human cancers was higher relative to normal controls and was also strongly associated with the lower overall survival (OS) and relapse-free survival (RFS) duration of CESC, ESCA, HNSC, KIRC, LIHC, and LUAD patients. This implies that TMED2 plays a significant role in the development and progression of these cancers. Furthermore, the TMED2 overexpression was also correlated with different clinicopathological features of CESC, ESCA, HNSC, KIRC, LIHC, and LUAD patients. TMED2-associated genes network was involved in 3 diverse pathways, and finally, few stronger correlations were also explored between TMED2 expression and its promoter methylation level, genetic alterations, and CD8+ T immune cells level. Conclusion In conclusion, via this in silico study, we have elucidated that TMED2 can serve as a shared diagnostic and prognostic biomarker in CESC, ESCA, HNSC, KIRC, LIHC, and LUAD patients of different clinicopathological features but, further in vitro and in vivo research should be carried out to confirm these findings.

Abstract
According to the previous reports, the collagen triple helix repeat containing 1 (CTHRC1) causes tumorigenesis by modulating the tumor microenvironment, however, the evidence is limited to a few human cancer subtypes. In the current study, we analyzed and validated the CTHRC1 expression variations in 24 different human cancer tissues paired with normal tissues using publically available databases. We observed that CTHRC1 was overexpressed in all the 24 major subtypes of human cancers and its overexpression was significantly associated with the reduced overall survival (OS) duration of head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), liver hepatocellular carcinoma (LIHC), Lung adenocarcinoma (LUAD), stomach adenocarcinoma (STAD), and Uterine corpus endometrial carcinoma (UCEC). This implies that CTHRC1 plays a significant role in the development and progression of these cancers. We further noticed that CTHRC1 was also overexpressed in HNSC, KIRC, LIHC, LUAD, STAD, and UCEC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of CTHRC1 associated genes in seven diverse pathways. We also explored few interesting correlations between CTHRC1 expression and promoter methylation, genetic alterations, CNVs, CD8+ T immune cells infiltration, and tumor purity. In conclusion, CTHRC1 can serve as a shared diagnostic and prognostic biomarker in HNSC, KIRC, LIHC, LUAD, STAD, and UCEC patients of different clinicopathological features.

Abstract
Background:COVID-19 pandemic had an unprecedented impact on the delivery of patient care. Rheumatology services had to rapidly adapt to virtual consultations at the onset of the pandemic. However, providing a high quality and effective service in a virtual setting can be challenging and therefore its prudent to do a formal review and gain patient feedback to ensure that these clinics are fit for purpose.Objectives:To evaluate the impact of first wave of COVID-19 pandemic on patients with autoimmune rheumatic conditions, assess delivery of rheumatology outpatient care and record patient feedback.Methods:This study included patients on the Rheumatology clinic lists between 3rd and 31st August 2020. An electronic survey questionnaire was developed and the survey link was sent to patients via a text message using secure IT platform. Data was collected on patient demographics, diagnosis, comorbidities, treatments, clinical/ laboratory confirmed COVID-19 diagnosis, treatment interruption, impact on work, personal protective measures taken and views on virtual consultations.Results:307 patients responded with 287 complete responses. 73.1%(223) were female and 32.4% (99) were >65 years of age. Rheumatoid arthritis was the most common diagnosis 41.6%(127). Hypertension was the commonest comorbidity 21.4%(64) followed by Chronic lung disease 17.3%(52). 28.8%(85) were on Hydroxychloroquine, 26.7%(79) Methotrexate, 14.2%(42) Sulfasalazine and 13.2%(39) on Prednisolone. 22.3%(66) were on Biologics: Anti TNF 12.8%(38), Tocilizumab 3.7%(11) and Rituximab 3%(9). 52.6%(161) shielded, 16.9%(55) self-isolated and 30.3%(93) only maintained social distance. 197 patients self reported as being vulnerable but based on their treatment,only 167 patiemts met the clinically extremely vulnerable (CEV) criteria and all of those received government shielding letter.3.6%(11) had lab confirmed COVID-19, 3.2%(10) had clinically suspected COVID-19 infection. 14.3% (43) had their treatment interrupted. 4.6%(14) were unable to work from home or maintain social distancing at work. 59.8%(182) had face-to-face consultation changed to virtual. 63.2%(189) were satisfied, 28%(84) neutral and 8.7%(26) reported dissatisfaction with their consultation. 50.5%(153) were happy to continue with virtual consultation but with an option of face to face only if necessary.For consultations post COVID-19, 59.4%(182) preferred a mixture of face to face and virtual appointments.Conclusion:Majority of our patients seem happy with virtual consultations as long as they are assured of a face-to-face consultation if needed. A minority(8.7%) however, were dissatisfied. Some of the suggestions were, use of video consultations and improvement in communication before the virtual appointments. Our survey also shows that our patients have adapted well to virtual consultations and many are keen to have virtual consultation in the longer term. In our survey, only 6.8%(21) patients reported definite or clinically suspected COVID-19. Possible explanations for this include strict compliance with government advice on social distancing/shielding and limited testing at the onset of the pandemic. More patients assumed themselves to be clinically CEV than those who were actually CEV based on their treatment which is not surprising because of high level of anxiety among patients due to rapidly spreading pandemic and multiple sources of information.This feedback provides useful data which will help us to plan the delivery of rheumatology services post COVID-19 pandemic. While face-to-face patient contact is needed for comprehensive disease assessment, teaching and training, a model for the future is likely to include a combination of face-to-face and virtual consultations. This could allow a greater capacity to see new patients and reduce waiting lists. Patients with uncomplicated and stable disease could be followed up in virtual clinics. There is also a need to formally incorportate the virtual consultations into the curriculum for Rheumatology trainees.Disclosure of Interests:None declared.

Abstract
Cotton (Gossypium hirsutum) wilt is one of the destructive disease caused by Fusarium oxysporum f. sp. vasinfectum and lead to 100% yield loss under favorable conditions. This study aims to estimate the potential of biological control agents Saccharothrix algeriensis NRRL B-24137 (SA) and chemical fungicides against cotton wilt pathogen under in-vitro and in-vivo conditions. The in-vitro study revealed that carbendazim showed maximum mycelia growth inhibition with a mean of 91% over control, which was further validated in glasshouse assay. In-vitro dual culture test of biocontrol agents with F. oxysporum determined that SA had a potential to inhibit mycelia growth by 68% compared to control. Further in glasshouse assay, the combination of the SA and carbendazim (10 µg/mL) showed a significant (p < 0.05) disease control. Moreover, results demonstrated that carbendazim and SA remarkably decreased the disease development up to 83% and subsequently, significant improvement was observed in the plant growth parameters (plant length, root length, and plant weight) compared to untreated plants. Conclusively, exploration and utilization of bioagent for fungal diseases in cotton may provide a better line with maximum efficacy and with lesser adverse effects, which will pave a way toward better consequences in fungal treatments.
