Rice seedlings of four commercial varieties (Nayab basmati, Kiran 434, Super basmati, and Pak 386) were screened against BLS in the field by using a randomized complete block design (RCBD). The present experiment was encompassed the evaluation of fermented farmyard manure, leaf manure, Boron, and NPK solution against BLS. The effect of different fungicides (Score, Flumax, Melodyduo, and Polyram) was also checked on the mycelial growth of Helminthosporium oryzae in-vitro and in-vivo. The results showed that Pak 386 was highly resistant with 17.22% disease severity and Super Basmati was found moderately resistant with 22.31% disease severity; variety Kisan 434 was found moderately susceptible (24.15%) and Nayab Basmati (24.82%) was susceptible. Among all NPK solutions showed the best results in growth enhancement, plant vigor as well as reduction in disease severity followed by FFYM, boron and leaf manure. Under in-vitro conditions, all the fungicides performed best at 150 ppm in terms of colony growth reduction. The maximum growth inhibition was recorded in Score followed by Flumax, Melodyduo, and Polyram. Score gave a significant reduction in BLS disease severity and maximized the agronomic attributes.

Bacteria of the Photorhabdus can survive independently and cause toxicity in a larger variety of insects. In the present study, insecticidal activity of non-portentous heat-stable metabolites of Photorhabdus luminescens was evaluated against Galleria mellonella. For this purpose, the culture extract of P. luminescens was injected into the G. mellonella larvae, which killed almost 90% of larvae within 48 h. The extract showed 100% insecticidal activity after heat treatment of 70°C for 30 min and even 60% and 40% activity lasted at 80°C and 90°C respectively. The extract also showed a high degree of thermal stability and was 100% actives after 60 min at 70°C. In addition, insecticidal activity was preserved up to 100% after all proteinase-K treatments (0 μg/mL to 50 μg/mL). The results revealed that the extracts were non-portentous and showed high thermal resistance and stability.</p> Ihsan Ullah, Khalid M.S.

For the purpose, semen from three buffalo bulls were collected for 3 weeks using artificial vagina (N=18; replicates). The qualified ejaculates were diluted employing tris-citric acid extender i.e., control did not receive any L-Carnitine and experimental groups having 0.5, 1.0, and 1.5 ng/mL of L-carnitine at 37°C with approximately 50 × 106 sperm/mL. The semen wascooled at 4°C and then equilibrated (4 hours), filled in straws (0.5 mL) at4°C, placed on LN2 vapours for 10 min and kept into an LN2 container. Thethawed semen was evaluated for post-thaw quality. The integrity of thesperm plasma membrane and motility (P˂0.05) was highest in theextenders having 1.0 ng/mL of L-carnitine as compared to the control(received no L-Carnitine). However, sperm chromatin integrity and viability(live sperm with intact acrosome) remained similar. It was concluded thatsupplementing 1.0 ng/mL L-Carnitine of extender can improve the post-thaw quality of cryopreserved sperm. Based on the results of the currentexperiments it is recommended to include L-carnitine extender to improvepost-thaw quality of buffalo sperm in terms of its motility and integrity ofits plasma membrane.</p> Saima Qadeer, Rabea Ejaz, Asma Ul Husna, Asima Azam, Syeda Laila Rubab, Ghulam Nabi, Sana Ullah, Shamim Akhter Copyright (c) 2021 Saima Qadeer, Rabea Ejaz, Asma Ul Husna, Asima Azam, Syeda Laila Rubab, Ghulam Nabi, Sana Ullah, Shamim Akhter https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/123 Sat, 11 Sep 2021 00:00:00 +0500 Association between Interleukin-10 promoter polymorphism with type 2 Diabetes mellitus http://ajlifesciences.com/ojs/index.php/ajls/article/view/157 <p>Type 2 diabetes mellitus is a multifactorial illness triggered by a complicated interplay of various genetic variants with various environmental variables. The quantity of replicated common genetic variants associated with type 2 diabetes mellitus has increased rapidly with the recent genome-wide association (GWA) research. Major health issue in the public are type 2 diabetes mellitus (T2DM) is common throughout the world. Diabetes mellitus incidence is growing and is anticipated to affect 300 million individuals by 2025. Diabetes has been suggested to alter patterns of cytokine expression as an immune-dependent illness. Insulin resistance (IR) is a disease that results in less than anticipated biological impact of a specified insulin concentration. Insulin resistance and insulin secretion decreased are both defined pathophysiology of T2DM. One of the most alarming health issues of the 21st century is the spread of diabetes around the globe. Our goal in this study was to identify the role of IL-10 polymorphism in T2DM patients. The average age of 60 median patients with type 2 diabetes mellitus (31 males and 29 females) ±SD (45.91667 ±16.08799), fasting blood sugar (FBS) is ±SD (184.25 ±57.76387), hypertension (35 positive/25 negative) and 60 non-diabetic controls (32 males and 28 females) is ± SD (47.31667 ±15.13722). The group (T2DM patients and their control) had not a substantial distinction (P=0.33) and in each group (CC, TT, CT) there was a comparison between IL-10 gene polymorphism. T2DM patients and healthy individuals are not associated with the polymorphism of the gene IL-10 (SNP rs 3021097 (C/T).</p> Hafiz Umair Hassan, Rana Haider Ali, Hafiz Muhammad Usman Siddiq, Fahad Ahmed, Hafiz Hanan Taj, Muhammad Farhan Rashid, Sami Ullah Copyright (c) 2021 Rana Haider Ali https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/157 Sat, 11 Sep 2021 00:00:00 +0500 Isolation and Identification of the Potential Novel L-asparaginase producing Bacillus Strains from Soil http://ajlifesciences.com/ojs/index.php/ajls/article/view/185 <p>L-Asparaginase is a well know enzyme for its antineoplastic potential and is widely used to treat acute lymphoblastic leukemia and lymphosarcoma. The present work describes the isolation and characterization of novel L-asparaginase producing Bacillus strains from soil. Soil samples were collected from three different locations such as fruit garden, dairy farm and agricultural land in Peshawar Khyber Pakhtunkhwa, Pakistan. The isolates were screened to produce L-asparaginase in growth medium supplemented with 1% L-asparagine using a phenol red indicator. Among 30 bacterial isolates, only two strains initially coded as A5 and FG7 showed L-asparaginase activity. Based on biochemical and 16S rRNA sequencing analysis, the isolate A5 and FG7 were identified as <em>Bacillus amyloliquefaciens </em>and <em>Bacillus proteolyticus </em>respectively. Different factors like pH and time were optimized for maximum L-asparaginase activity. <em>Bacillus amyloliquefaciens</em> showed maximum asparaginase activity at pH 7 after 24 hours incubation at 30<sup>o</sup>C, while <em>Bacillus proteolyticus </em>showed optimum activity at pH 7 after 48 hours of incubation at 30<sup>o</sup>C. The present study first time reported the production of L-asparginase enzyme from <em>Bacillus amyloliquefaciens </em>and <em>Bacillus proteolyticus.</em></p> Naushaba Nazli, Rukhsar Masood, Muhmmad Salman, Rukhsar Masood, Bilal Nasir, Farah shireen, Asif Mehmood, Sudhair Abbas Bangash, Farrukh Hussain, Shabir Ahmad Copyright (c) 2021 Naushaba Nazli, Rukhsar Masood, Rukhsar Masood, Muhmmad Salman, Bilal Nasir, Farah shireen, Asif Mehmood, Abbas, Shabir Ahmad, Dr. Farrukh Hussain https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/185 Sat, 11 Sep 2021 00:00:00 +0500 Assessment of Detection and Treatment Response of Hepatitis C viral Infection in District Mardan Pakistan http://ajlifesciences.com/ojs/index.php/ajls/article/view/142 <p>Hepatitis C virus is known to be major public health issue around the globe. The aim was to investigate the treatment and detection of HCV infection in general population of District Mardan. Presently no standard treatment is available for the cure of Hepatitis C viral infection, attributed possibly to the hyper variations in HCV genome, expressing several distinct HCV genotypes. For a period of 5 months (June 2016 - November 2016), 270 suspected individuals visited the main hospital of Mardan Medical complex (MMC), were interviewed. Among them 100 individuals were diagnosed by ELISA and PCR for HCV detection at the diagnostic laboratory of MMC. A total of 170 HCV patients were treated at the MMC, with oral medicine or interferon vaccines and the response were monitored by PCR after treatments. Our result showed that high sensitivity for genome-based PCR detection of HCV in comparison to viral coat protein detection by ELISA. The assessment of treatment strategies for HCV showed high response for presently available medicines i.e., Sovaldi, Sofiget, Sofohil, Ocvir and sofosbuvir in comparison to interferon and pig interferon. The accurate and early diagnosis of the HCV infection is crucial for effective treatment strategies. Thereby PCR detection should be the proffered method for specific and accurate detection of HCV infection. The standard medicine available presently proved better treatment method for HCV infection in comparison to interferon vaccination.</p> Atif Kamil, Aurang Zeb, Farooq Hussain, Muhsin Jamal, Azmat Ali, Muhammad Shah, Ayaz Ahmad, Jawad Khan, Faheem Anwar, Nabila Copyright (c) 2021 Atif Kamil, Aurang Zeb, Farooq Hussain, Muhsin Jamal, Azmat Ali, Muhammad Shah, Ayaz Ahmad, Jawad Khan, Faheem Anwar https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/142 Sat, 11 Sep 2021 00:00:00 +0500 Unveiling the genetic divergence and phenotypic association in elite Pakistani wheat (Triticum aestivum L.) genotypes http://ajlifesciences.com/ojs/index.php/ajls/article/view/88 <p>The present study was designed to assess genetic divergence between commercial bread wheat genotypes based on yield and its related traits and to carry out phenotypic correlation. Twenty bread hexaploid wheat varieties were assessed for mean performance, correlation analysis and genetic distance. Randomized complete block design was used with three replications during growing season, 2018-2019 at Wheat and Barley Research Institute, Tandojam. The mean squares depicted significant differences (P&lt;0.01) for all the investigated traits among the tested genotypes, proving that used genetic resources possess a great potential for further breeding experiments. Regarding mean performance, the genotypes Sassui and TD-1 displayed desirable performance for a variety of traits, unveiling their importance in wheat breeding programs. The results also showed that tillers plant-1, grains spike-1 and seed index developed significantly positive (P&lt;0.05) interrelationship with grain yield plant-1. This demonstrates that genotypes possessing higher extent of these traits may be chosen in selection for developing high yielding bread wheat genotypes. The larger genetic distance was witnessed between Johar-78 and TD-1, followed by SKD-1 and TJ-83, SKD-1 and Mehran-89, SKD-1 and Johar-78, TD-1 and Khirman, TJ-83 and Imdad-05, Mehran-89 and TD-1 and Johar-78 and TJ-83. These paired showed wide genetic distances, which may also be preferred in wheat hybridization program.</p> Naila Gandahi, Ghulam Hussain Jatoi, Abdul Wahid Baloch, Asadullah Mari, Liaquat Ali Bhutto, Mir Yar Muhammad Khan Talpur, Nasreen Fatima, Tanweer Fatah Abro, Rong Shu Zhang Copyright (c) 2021 Abdul Wahid Baloch https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/88 Sat, 11 Sep 2021 00:00:00 +0500 Stable Vesicle Production from Bacterial Total Lipid Extracts http://ajlifesciences.com/ojs/index.php/ajls/article/view/170 <p>Liposomes are the small vesicles, made up of lipids. Based on their structure, they can be called as simplified cell structure.

Seeds of berseem can be produced in the country for which research on seed production is preferred, as most research works on berseem conducted on forage production only. Thus, an experiment comprising four levels of nitrogen (0. 15, 30, and 45 kg ha<sup>-1</sup>) and four levels of foliar zinc (0, 400, 600, and 800 g ha<sup>-1</sup>) was designed with the purpose to find out appropriate levels of nitrogen and foliar zinc to get maximum seed yield of berseem. The experiment was conducted at the Agronomy Research Farm of The University of Agriculture Peshawar during winter 2014-2015 by using a randomized complete block design replicated three times. The results indicated that both nitrogen and foliar zinc application significantly (P˂0.05) influenced fresh (13219.41 kg ha<sup>-1</sup>) and dry fodder yield (5538 kg ha<sup>-1</sup>), head m<sup>-2</sup> (1963), number of seeds head<sup>-1</sup> (50), biological yield (8535.4 kg ha<sup>-1</sup>), thousand seed weight (2.6 g), seed yield (261 kg ha<sup>-1</sup>), seed recovery (68%). A significant effect was recorded only by different nitrogen levels on the number of flower head<sup>-1</sup> (78) and harvest index (3.19%), whereas zinc significantly influenced plant height (80 cm). Both nitrogen and foliar zinc application increase fresh and dry fodder yield, plant height, head m<sup>-2</sup>, seed head<sup>-1</sup>, thousand seed weight, seed yield, and seed recovery. It was concluded that the application of nitrogen (45 kg ha<sup>-1</sup>) and zinc (600 g ha<sup>-1</sup>) in foliar spraying produces the maximum yield of the berseem crop.</p> Muhammad Asim, Quaid Hussain Copyright (c) 2021 Quaid Hussain https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/130 Sat, 11 Sep 2021 00:00:00 +0500 Dietary intake to help prevent Covid-19 implications: The devil is in the detail http://ajlifesciences.com/ojs/index.php/ajls/article/view/181 <p>One of the most frequent antecedents of mortality in world is coronavirus that proceeds multitude metabolic disorders and is consequence of damaged lungs that is ultimately caused by contagious infection and virus called coronavirus. It effects people of every age mostly dominating in child, aged, people who have already poor immune system and lungs related disorders. It has tremendous effects on body affecting physical, emotional, cognitive and intellectual abilities as well. It leads to various clinical moderate to severe complications including acute respiratory distress syndrome (ARDS), pneumonia, coughing up blood, persistent chest pain, fever, SOB (shortness of breath), coughing up sputum, chills, sore throat, respiratory sputum production (phlegm), loss of sense and smell, headache, muscle aches, rashes and diarrhea etc. One of the most imprudent factors examined in these patients is acute respiratory distress syndrome (ARDS) as well which refers to respiratory failure, a mechanism in which body is unable to respond normally sequentially results by high level of widespread inflammation in lungs. Penurious immune system which contributes to higher rate of mortality worldwide present strong association with COVID-19. Metabolic disturbances contribute to the development and progression of respiratory distress, as well as they have serious consequences in next stages of life that can have harmful effects on health. In this review we will discuss the pathophysiology as well as the signs and symptoms of COVID-19, the morbidities related to this disease and the treatment required controlling this disorder.</p> Sana Noreen, Abdul Rehman, Rabia Kanwal, Saba Saleem, Ayesha Sadiqa, Mudassir Khan Copyright (c) 2021 Sana Noreen, Abdul Rehman, Rabia Kanwal, Saba Saleem, Ayesha Sadiqa, Mudassir Khan https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/181 Sat, 11 Sep 2021 00:00:00 +0500 Effects of Staphylococcus aureus hemolysin toxins on blood cells and association with skin and soft tissue infections http://ajlifesciences.com/ojs/index.php/ajls/article/view/169 <p>Staphylococcus aureus (S. aureus) is gram positive, catalase positive cocci which belongs to the family of Staphylococcaceae and is long known as clinical and foodborne pathogen. The emergence of multidrug resistance strain of S. aureus which is methicillin resistant S. aureus (MRSA) challenges the health care system because it can cause wide variety of hospital and community acquired skin and soft tissue infections which are difficult to treat. The virulence of S. aureus is because of different factors which includes toxins, enzymes and superantigens. S. aureus produce variety of exotoxins, enterotoxins and exfoliative toxins which contributes to the virulence of S. aureus. Hemolysin toxins produce by S. aureus strains are associated with different skin and soft tissue infections (SSTIs) and can cause the lysis of RBCs. Hemolysins are regulated by accessory gene regulator (agr) and is required for the enhanced expression of virulence factors secreted by S. aureus. Hemolysins have leucolytic activity and can help in iron scavenging from host. The most important toxin is alpha hemolysin which can induce the apoptosis and cause the lysis of epithelial cells, erythrocytes and keratinocytes. Human immune cells are affected by beta hemolysin and gamma hemolysin is a biocomponent toxin. Delta hemolysin is low molecular weight exotoxin which belongs to the class of phenol soluble modulins.</p> Adnan Shahid, Afsheen Rafiq Copyright (c) 2021 Adnan Shahid https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/169 Sat, 11 Sep 2021 00:00:00 +0500 Cell Transplantation Therapies to Reverse Type 1 Diabetes: A review http://ajlifesciences.com/ojs/index.php/ajls/article/view/116 <p>Stem cell technology is demonstrating promising advancements in cure of diseases due its differentiation ability. Type 1 diabetes is mainly caused by autoimmune β cells destruction. In this review, we focus on treatment procedures of Type 1 Diabetes (T1D) with numerous stem cells (SCs) i.e hPSCs, MSCs, hESCs, BMSCs, AFSCs, HSCs and islet cells (that are not stem cells but they are approved worldwide and are being successfully used to permanently reverse T1D). A brief overview of this disease along with the advancements in treatment of T1D with stem cells is discussed. Biomaterial encapsulation to avoid immune rejection and improved immunomodulation and immune tolerance via drugs /bioengineering techniques makes the outcomes of SC therapies more efficient and productive, hence, proving to be another future milestone of completely reversing type 1 diabetes especially in those patients who got clinically diagnosed at an early stage and then received prompt treatment of either restoration of already available β cells functionality or transplantation of purified and functional SCs differentiated insulin producing cells to normalize the glycemic control and homeostasis.</p> Amrah Inam, Zia Alam, Obaid Ullah Shah, Misbah, Fanxiong Shi Copyright (c) 2021 Amrah Inam, Obaid Ullah Shah, Misbah, Zia Alam https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/116 Sat, 11 Sep 2021 00:00:00 +0500 Organ Transplantation, Pros, Cons, and illustrations: A Basic Awareness to the Public http://ajlifesciences.com/ojs/index.php/ajls/article/view/139 <p>Solid-organ transplantation saves the lives of patients affected by end-stage organ failure and enhances the quality of life. It has been developed in the last two decades and provides amazing results for children and young people and increases the growing number of elderly transplant patients with organ transplantation. Use of corticosteroids, vaccines, and other drugs to avoid infection in diseased patients. Several approaches have been developed to prolong organ obtainability, including living donor liver transplantation, split liver transplantation, and application of expanded criteria for donors and donation after circulatory death grafts. Unprincipled practices in many countries are due to the availability of organs. Organ transplantation requires screening and comparative contraindications in the recipient. The authors want to give a general awareness to the public, which is essential to know for donating and receiving organs from others.</p> Hindustan Abdul Ahad, Chinthaginjala Haranath, Bhupalam Pradeepkumar, Chittem Vinay, Chalamatigari Yoga Chandra Sekhar Reddy, Mitaigiri Shaik Sajid, Balaiah Gari Mani Raja Rao, Manjoor Ahamad Syed , Shaik Mohammed Yusuf Copyright (c) 2021 Hindustan Abdul Ahad https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/139 Sat, 11 Sep 2021 00:00:00 +0500 Increased pollution due to COVID-19 pandemic and bioremediation: A dire need of management http://ajlifesciences.com/ojs/index.php/ajls/article/view/158 <p>The purpose of this study was to provide an overview of the effects of COVID-19 on macro-plastic pollution and to consider short-term and long-term scenarios for its possible environmental and human health consequences and to discuss possible strategies to address and overcome key challenges. It was emphasized that, whether or not they are involved in a healthy health crisis, future actions should reflect the balance between public health and environmental protection, as there is no doubt that they are interrelated with bioremediation and microbial metabolism in the presence of optimal environmental conditions. Bioremediation uses natural and psychological microorganisms to break down toxic and harmful substances aerobically and anaerobically. It can be handled by a mixed microbial consortium or pure microbial strains on site (in situ) or off site (in the case of case) Phyto therapy or even natural care. Nutrients suitable for impurities, especially petroleum hydrocarbons are researched technologies for us, for this a biotechnological approach designed for bioremediation and observation. COVID 19 Pandemic pushed the world into a new challenge of waste management. In general, physicochemical technologies are used, which allow for proper ecological biomedical processes. Some bacteria are mobile, feel the contamination, and move towards it to neutralize it. This review emphasizes on current pollution, which is result of COVID 19 pandemic, as people follow use and discard strategies for different things which is a threat to our environment.</p> Malali Khan Copyright (c) 2021 Malali Khan https://creativecommons.org/licenses/by-nc/4.0 http://ajlifesciences.com/ojs/index.php/ajls/article/view/158 Sat, 11 Sep 2021 00:00:00 +0500
