Hence the current work was aimed to evaluate the effect of different solvents extract (n- hexane, ethyl acetate, methanol and water) of P. niruri for in vitro anti-urolithiatic properties in terms of inhibition activity on CaOx by using the rate of CaOx aggregation assay and dissolution of calcium oxalate (CaOx) crystal by using titrimetry method. Cystone was used as positive control. The effects of cystone on slope of nucleation and aggregation as well as growth of CaOx were evaluated spectrophotometrically. The highest yield percentage of P.niruri was occupied by methanol (5.74 %). The maximum inhibition against aggregation of CaOx crystals was also occupied by methanol (66.67 % ± 1.61) and was comprised with alkaloid, steroid, terpenoid and tannin. Dissolution effect on calcium oxalate crystals indicates that the aqueous extracts of P. niruri was found to be more effective in dissolution of CaOx with 63.33 % ± 1.44. P. niruri significantly (P < 0.05) inhibited the slope of nucleation and aggregation of CaOx crystallization, and reduced the crystal density. The results of the present study confirmed that P. niruri leaves can be used as remedial mediator for urolithiasis. However, further studies are required for isolation and identification of active constituents and their in-vivo confirmation.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"6 1","pages":"81-86"},"PeriodicalIF":0.0,"publicationDate":"2021-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87942047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To feed the hunger population, safe and nutritious vegetables are growing concern as they are being polluted by heavy metals. The present study was conducted to investigate the concentration of heavy metals such as cadmium (Cd), chromium (Cr), lead (Pb), nickel (Ni), iron (Fe), manganese (Mn), and zinc (Zn) in highly consumed vegetable collected from peri-urban markets of Rawalpindi and Multan region. Health risk associated with the consumption of these vegetables in term of estimated daily intake of metals (EDIM) and health risk index (HRI) was also evaluated among local consumers. Results showed that mean values of cadmium (Cd), and lead (Pb) in all vegetable samples from both region were exceeding the respective MAL set by FAO/WHO. Estimated daily intake of heavy metals was found below than the permissible limit. EDIM showed following decreasing trend Fe > Zn > Mn > Ni > Pb > Cr and Cd, respectively. The health risk index (HRI) for all heavy metals were less than the threshold level (1), indicating no significant threat to the local population through the consumption of these vegetables.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"8 1","pages":"55-63"},"PeriodicalIF":0.0,"publicationDate":"2021-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84280236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Micro-organisms, phosphorus solubilizing bacteria (PSB) and sulphur oxidizing bacteria (SOB) have the ability to make P accessible for optimum plant growth, under conditions of nutrients disparity. Therefore, six treatments i.e. control, Yz dose of NPK, full recommended dose of NPK, Yz NPK+ SOB, Yz NPK + PSB and Yz NPK + SOB+ PSB were applied in a field experiment to investigate the integrated role of SOB and PSB with NPK fertilizers for enhancing the maize production. The treatment was concluded to have major impact on agro-morphological traits, seed quality and growth parameters of maize. Results depicted that the use of Yz NPK + SOB + PSB gave maximum germination count/plot (151.33), plant height (189.03 cm), number of ears/plant (1.60), grains/ear (472.33), 1000-grain weight (305.67 g), grain yield (5350.50 Kg/ha), harvest index (31.23%), leaf area (379.77 cm2), total dry matter accumulated (181.43 g/plant), crop growth rate (30.60 g/day), net assimilation rate (9.31 g/day) and protein contents (8.49%).","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"61 1","pages":"43-48"},"PeriodicalIF":0.0,"publicationDate":"2021-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85107626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanocarriers have achieved significant importance in the stabilization of proteins and peptides, anti-cancer drug camptothecin (CPT) and bone tissue engineering offering improved buccal access and protection according to the desired function. Moreover, tailored formulation along with functionalization and bio- compatibility has importance in fabrication of nanoparticles for proteins or peptides via oral delivery systems, which has advantage over parenteric delivery systems because of their comfort running and observance to treatment. The review summarizes interesting approaches on existing publications for drugs such as proteins or peptides carrier nanoparticles with special focus on porous silicon for delivery systems.

Sabz Pari at Agricultural Research Institute, Dera Ismail Khan, Khyber Pakhtunkhwa, Pakistan. A field experiment was set out in randomised complete block design with NAA application as a main factor. Different NAA concentrations were obtained by dissolving NAA in distilled water at the rate of 0 (control), 10, 30, 50, 70, 90 and 110 mg/L. NAA treatments along with control were foliar applied to okra plants after 30 days of sowing. Lower concentration of NAA (30-50 mg/L) stimulated maximum increase in plant height (59.5-57.2%), number of leaves/plant (50.4-45.5%,), total plant leaf area (113.9-119.4%), internodes/plant (72.5-61.6%), internode length (53.2-44.5%), pod diameter (53.5-49.9%), pod fresh weight (126.8-111.8%), pod yield (271.2-255.8%) compared to control (0 mg NAA/L). NAA at higher concentrations (>50 mg/L) had a supressing effect on most parameters. It was inferred that yield production in okra is influenced by multiple yield-determining component traits and their mutual interactions which could be manipulated by the application of NAA. Foliar application of NAA (30-50 mg/L) have a beneficial impact on plant characters and yield of Okra, hence recommended in Okra cultivation.","PeriodicalId":19784,"journal":{"name":"Pakistan journal of scientific and industrial research","volume":"1 1","pages":"35-45"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77210712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
