These plants are rich source of valuable antibacterial and food preservative agents. In Pakistan, tons of vegetables are discarded as inedible part during peeling and cutting before cooking as well as due to unavailability of proper preservative techniques. The present study was designed to check antibacterial and food preservative potential of commonly vegetables of Pakistan. Methods: The aqueous and ethanolic extracts of edible and inedible parts of <em>Momordica charantia</em>, <em>Pisum sativum</em> and <em>Abellmoschus esculentus</em> were made and tested against <em>Escherichia coli, Staphylococcus aureus, Salmonella typhimorium, Pasterurella multocida, Lactobacillus bulgaricus </em>and <em>Micrococcus luteus</em> by disc diffusion method<em>.</em> Zones of inhibition were measured. Results: Highest antibacterial activity was observed in ethanolic extracts of inedible parts of <em>Pisum sativum</em>. Moderate activity was observed from edible parts of <em>Momordica charantia</em>. The study has highlighted the use of vegetables as edible vaccines.</p> 2023-01-03T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology http://pjbb.wum.edu.pk/index.php/ojs/article/view/161 Gender linked negative consequences of “Nigella sativa” seeds and “Plantago ovata” husk on fibrosis in the energy-rich diet (ERD) induced nonalcoholic fatty liver disease (NAFLD) 2022-10-12T10:31:25+00:00 Afshan Syed Abbas afshan.syed@ue.edu.pk Mudassir Hassan Abbasi muddygcs@gmail.com Babar Khawar babarkhawar@yahoo.com Faiza Jabeen drfaizajabeen@ue.edu.pk Asia Shad asia.shad0309@gmail.com Nadeem Sheikh nadeem.zool@pu.edu.pk <p><strong>Background: </strong>Nonalcoholic fatty liver disease (NAFLD) is a developing liver problem mainly linked with the consumption of an ‘energy-rich-diet (ERD) in Asian countries including both females and males. NAFLD is associated with fibrosis in advanced stages. Medicinal herbs are being used to cut down the excessive fat of the body conventionally. Therefore, the current study was aimed to evaluate the lipid lowering factor against ERD induced fibrosis.</p> <p><strong>Materials and methods:</strong> 40 female (F) and 40 male (M) <em>Rattus norvegicus</em>, subdivided as four groups Groups 0, I, II and III according to their nutritional content. Group-0 received 100% rat chow and Group-I received ERD. Group-II and Group-III received ERD supplemented with 5% <em>Nigella sativa</em> seeds/<em>Plantago. ovata </em>husk per kg ERD, respectively.</p> <p><strong>Results: </strong>Histopathological evaluation of the liver showed pericellular and portal and fibrosis in both F-I and F-II. Radial fibrosis was detected in the M-II group, and peri lobular as well as bridging fibrosis between portal triads in the M-III and F-III groups.</p> <p><strong>Conclusion:</strong> In the light of the present findings, it is inferred that male livers were more susceptible to DRE-induced fibrosis. <em>N. sativa </em>seeds proved auspicious in minimizing fibrosis, whereas <em>P. ovata </em>pods caused advanced liver fibrosis with DRE.</p> <p>&nbsp;</p> 2022-12-23T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology http://pjbb.wum.edu.pk/index.php/ojs/article/view/130 Phytochemical and Antimicrobial Studies of Salvadora persica, Prosopis cineraria and Tamarix aphyla Plants from Cholistan, Pakistan 2022-10-13T08:34:39+00:00 Dr Mirza Imran Shahzad mirza.imran@iub.edu.pk Muhammad Safdar Hussain safdar.danish1103@gmail.com Irfan Saeed irfansaeed168@gmail.com Hina Ashraf hinaimranmirza@gmail.com Summiyya Anwar herry12357@gmail.com Mussarat Ramzan marain79@gmail.com <p>Viral and bacterial infections are causing havoc to human health, wildlife, poultry and livestock since long. Current study was designed to carry out investigation of the antiviral and antibacterial potential of leaves of <em>Salvadora persica</em>, <em>Prosopis cineraria</em> and <em>Tamarix aphyla</em> from Cholistan by using HA/IHA titers and Agar disc diffusion methods. Extracts of these plants were tested against 4 different viruses i.e. Newcastle Disease Virus (NDV), Infectious Bursal Disease Virus (IBDV), Infectious Bronchitis Virus (IBV) and Avian Influenza Virus (AIV-H9N2) and 5 different bacteria i.e. <em>Proteus vulgaris</em>, <em>Klebsiella pneumonia</em>, <em>Escherichia coli</em>, <em>Pseudomonas aeruginosa</em> and <em>Staphylococcus aureus</em>. The drug ampicillin was used as a positive control. The results indicate that the n-hexane and ethyl acetate extracts were more effective against viruses and bacteria as compared to ethanol, methanol, <em>n</em>-butanol and aqueous extracts. In comparison of plants, the extracts of <em>S. persica</em> were found to have highest antiviral potential while on the other hand the extracts of <em>T. aphyla</em> showed the best activity against bacteria. Overall these plants were most effective against IBDV and least effective against NDV and in comparison of bacterial pathogens, these plants were found to be highly effective against <em>P. vulgaris</em> and least effective against <em>P. aeruginosa.</em></p> <p>&nbsp;</p> 2022-12-31T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology http://pjbb.wum.edu.pk/index.php/ojs/article/view/185 Genotypic Characterization of Cotton (Gossypium hirsutum L.) for Physiological Attributes Associated with Water Stress Tolerance 2023-01-13T15:35:56+00:00 Khadim Hussain khnajam@gmail.com Muhammad Akbar malikakbarccri@gmail.com Farzana Ashraf farzanabalochso@gmail.com Muhammad Idrees Khan peer60000@gmail.com Muhammad Ilyas Sarwar mianilyas222@yahoo.com Fida Hussain fida1385@gmail.com Javed Iqbal iqbal80@yahoo.com Hafiz Muhammad Imran Imrananjum2005@yahoo.com Mubashir Islam Gill gillccri@gmail.com Hafiz Naveed Ramzan naveedramzan_uaf@hotmail.com <p>Drought has an impact on agricultural growth and development, which significantly reduces output and degrades produce quality. Fifty cotton genotypes were tested in the field for performance under artificially produced water deficit stress conditions. In 2015, sowing was carried out in the first week of May with two sets of every genotype in each replication. While the other set continued to be stressed by a water shortage, one set was regularly irrigated. The crop was allowed to grow for a duration of four weeks. Data on various physiological markers related to different genotypes' resistance to water stress were gathered. The findings showed that under normal and stressful conditions, the genotypes differed significantly (p 0.01) in a number of physiological variables e.g.&nbsp; relative water content, cell damage, leaf water potential, excised leaf water loss, osmotic potential, and stomatal conductance.

For this purpose, thirty male albino mice of 8 weeks age were kept in animal house for 10 days habituation and then they were divided into three groups: group I (control group), experimental group II (treated with fresh mecobalamin), experimental group III (treated with expired mecobalamin). ANOVA based significant results were observed for mice body weight, arterial diameter and its wall thickness in renal histological sections of both experimental groups. Similarly, significant changes were observed in arterial diameter, venous wall thickness and lobule diameter in hepatic histological sections. It was concluded that regular long term intake of fresh mecobalamin results in over dosage based side effects whereas exposure to expired mecobalamin causes renal and hepatic tissues necrosis, along with irregular variations of vasodilation and vasoconstriction in blood vessels. Thus, a programmed general public campaign is required to develop awareness that mecobalamin should be used according to prescribed dosage rather than self-medication and before use, the expiry date should be checked and expired drugs should be strictly prohibited to avoid physiological disturbances.</p> <p><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </strong></p> 2022-10-18T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology http://pjbb.wum.edu.pk/index.php/ojs/article/view/177 Exogenous Application of Salicylic acid Mitigates heat-induced Oxidative Stress in Barley (Hordeum vulgare L.) 2022-12-27T18:41:19+00:00 Maryam Zahra maryam_zahra00@yahoo.com Sumaira Rasul dr.sumaira@bzu.edu.pk Fozia Saeed fozia.saeed12@yahoo.com Lubna Rasool lubnarasool@uosahiwal.edu.pk Hamid Manzoor dr.hamid@bzu.edu.pk <p>Due to climate change, heat stress is becoming one of the most disastrous abiotic stresses and responsible for huge crop losses in different regions of the world. Adverse effects of heat stress can be encountered by the use of phytohormones and salicylic acid (SA) is one of those hormones having capability to protect plants from heat stress. Current research work was planned to explore the defensive role of exogenously applied SA in barley cultivars under high temperature. For this purpose, two weeks old plants of four barley cultivars (Jau-87, B-10007, B-14003 and B-14037) were foliar sprayed with SA (2 mM and 5 mM) for 24 hours and then were exposed to heat stress (42 °C). Our results showed that heat exposure made a prominent decrease in chlorophyll contents, carotenoids, relative water contents, antioxidant enzymes activities (superoxide dismutase, peroxidase and catalase) and anthocyanin activity while increased lipid peroxidation (malondialdehyde), hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) contents and proline accumulation. Foliar application of SA enhanced plants photosynthetic pigments (chlorophyll <em>a</em>, <em>b</em> and total), RWC, proline, and anthocyanin under control and stressed conditions. SA pre-treatment under heat stress reduced H<sub>2</sub>O<sub>2</sub> and MDA levels whereas activities of reactive oxygen species (ROS) scavenging enzymes were elevated by all tested SA concentrations. These results suggest that SA can efficiently remove H<sub>2</sub>O<sub>2</sub> by increasing activity of above mentioned enzymes hence reducing oxidative stress and malondialdehyde (MDA) contents. Proline, an important amino acid that acts as an anti-oxidative system in plants also highly accumulated in SA co-treated heat-stressed plants. Our results also showed that 2mM SA is more effective in protecting barley plants under heat stress as compared to 5mM SA. This concluded that defensive nature of SA regulates different physiological and biochemical processes to induce heat tolerance in barley.</p> 2022-12-30T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology http://pjbb.wum.edu.pk/index.php/ojs/article/view/145 Obesity a key risk factor for offsprings with diabetes mellitus, of Type II diabetic parents 2022-10-24T06:51:50+00:00 Hafiza Nida Shehzadi t@wum.edu.pk Umbreen Shabbir t@wum.edu.pk Hamama Islam Butt t@wum.edu.pk Hira Muzzamal t@wum.edu.pk Shahzad Nadeem t@wum.edu.pk Ayesha Abbas t@wum.edu.pk Ayesha Yaqoob t@wum.edu.pk Hafiz Muhammad Azeem t@wum.edu.pk Shahzad Bashir shahzad1840@gmail.com <p>Around the globe Type II diabetes is a major health issue that proceeds both from inheritance-environment interaction along with varied health risk factors like obesity and sedentary lifestyle. The body mass index (BMI) significantly linked diabetes to insulin resistance in people with high blood glucose levels. The main objective of this study was to determine a link between obesity and parental history (PH), which is a key risk factors for onset of Diabetes Mellitus (DM) in the offsprings of Type II diabetic parents. This study includes a total of 70 offsprings i.e. 50 obese and 20 non-obese offsprings from both genders with a familial history of diabetes (FHD). The important observations like BMI, Waist/Hip ratio, FBG test, 2hr OGTT and Urine examination were determined in control and test group individuals respectively. Thus, it is concluded that obesity and overweight are the key risk factor for onset of diabetes in offsprings as the mean of FBG was 115.5mg/dl as compared to 75.5mg/dl in controls and mean of 2-hr OGTT was 155.5mg/dl as compared to 89.9 mg/dl in controls respectively. However, cautious modifications in diet and exercises regime can aid to diminish or delay the onset of diabetes in offsprings with a prior history of Type II diabetic parents.</p> 2022-12-31T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology http://pjbb.wum.edu.pk/index.php/ojs/article/view/69 Evaluation of Therapeutic Potential of Natural Resources against Breast Cancer 2022-06-03T17:22:13+00:00 Aqsa Munir aqsamunir986@gmail.com Ishrat Fatima ishratfatima948@gmail.com Zelle Humma hummabiochem@gmail.com <p>For ages, natural resources plants and herbs have been used in homeopathic medicines to prevent and cure multiple diseases.

In a greenhouse environment, sixty days after planting, the cry 1Ac gene's expression peaked. At 60 DAP, the variety Bt.CIM-598 (1.871 g/g) expressed the most toxin of any genotype. Throughout the cropping season, larvae of the <em>Helicoverpa armigera</em> were gathered from every section of the nation that produces cotton. <em>H. armigera</em> larvae that were captured in the field were raised on artificial feeds. There was a negative relationship between the DAP and the amount of <em>Cry1Ac</em> protein (-0.332). The greatest amount of death was seen when first-instar larvae consumed the leaves of 60 DAP plants. It was found that transgenic variants had a considerable effect on the percentage mortality of <em>H. armigera</em>. MNH-886 larvae showed the highest mortality percentage when fed on leaves that were harvested 30 DAP (days after planting). When larvae were fed on 60 and 90 DAP leaves on CIM-598 and IR-1524, the mortality rate was greater. However, AA-802 had the highest death rate when larvae were fed on 120 DAP leaves. The variety with the highest death rate was CIM-598. When <em>H. armigera</em> consumed 60 DAP leaves, the greatest overall mortality was noted. The plant-toxin interaction in cotton varied depending on a number of physiological changes in plants. Regardless of plant age or variety, the highest rate of mortality of<em> H. armigera</em> larvae was seen after feeding 48-hour of treatment or feeding.</p> <p>&nbsp;</p> <p>&nbsp;</p> 2022-12-31T00:00:00+00:00 Copyright (c) 2022 Pakistan Journal of Biochemistry and Biotechnology
