A solution of CCl4 in paraffin (1:1) was used to induce liver damage in albino rats. The liver and kidney function tests were carried out by oral administration of varying doses (200, 400, and 600 mg/kg) of the bulk alkaloid to different groups of albino rats for 14 days. The rats were subsequently sacrificed, and the hepatocurative and histopathological assessment of the liver and kidney were carried out to determine the serum albumin, total protein, cholesterol (CHOL), triglycerides (TAG), low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), blood urea nitrogen (BUN) and creatinine. The total protein, serum albumin, and HDLs were significantly (p < 0.05) increased by alkaloid fraction of V. doniana to values compared with the control. The results also showed that serum CHOL, TAG, LDLs, BUN, and creatinine were significantly reduced (p < 0.05) in rats treated with alkaloid fraction compared with untreated. The normal cellular architecture of the liver destroyed by the standard hepatotoxin was restored by the alkaloids. The alkaloids of V. doniana reverse the CCl4-induced hepatocellular damage, supporting its use in managing liver-associated diseases.","PeriodicalId":18009,"journal":{"name":"Letters in Applied NanoBioScience","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86159936","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}

An important issue is related to centrifugation's effect on the concentration efficiency of cryoconcentration. The present work's main objective was to study the Block cryoconcentration assisted by centrifugation (BCCC), their effects on the polyphenols, and antioxidant activity applied to prickly pear juice. Prickly pear juice was obtained, Bx, pH, titratable acidity, color, total reducing sugars, total phenolic content (TPC), flavonoids, FRAP, DPPH, and process parameters (efficiency (η), concentration index (CI), and solute yield (Y)) were evaluated. Data obtained for physicochemical parameters showed high values of °Bx in cryoconcentrated samples, pH values decreased in treated samples, and total titratable acidity increased, total reducing sugars were higher in samples treated at the lower time of centrifugation, all experimental samples showed noticeable color changes. Higher total phenolic and flavonoid content were observed in samples treated at 15 min of centrifugation; DPPH and FRAP tests were highly correlated with TPC and flavonoid content (R2> 0.96). High efficiency and concentration index were observed; however, a low value of solute yield was found in cryoconcentrated juice. The use of cryoconcentration for prickly pear juices shows good results for physicochemical parameters, preservation of bioactive, and process parameters with the exception of solute yield.","PeriodicalId":18009,"journal":{"name":"Letters in Applied NanoBioScience","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90818632","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}

Among other metal nanoparticles, ZnS NPs are important due to their utilization in agriculture. Zinc sulfide nanoparticles have great potential to enhance agriculture production. The co-precipitation method was used to make ZnS nanoparticles, and morphological features were investigated using X-ray diffraction (XRD) and a transmission electron microscope (TEM) to determine size. The average particle was near ~3 nm calculated using XRD, close to the TEM study. Tomatoes, which belong to the Solanaceae family, are one of India's most important vegetable crops. The tomato plants were sprayed with a graded concentration of zinc sulfide nanoparticles (ZnS NPs) based nano-fertilizer four times at a 15-day interval and a control. At the flowering time, growth parameters such as plant height were measured. Nanofertilizer-treated plants showed increased weight and quality of crop yield. This paper elaborates the synthesis, characterization, properties, and application of ZnS NPs as nano-fertilizer on tomato plant growth. Developing nano-based fertilizer would be a new technique in this field, as nano-fertilizers are beneficial and less toxic to chemical fertilizer and improve soil fertility.","PeriodicalId":18009,"journal":{"name":"Letters in Applied NanoBioScience","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75673518","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}

Out of all methods to produce nanoparticles, the green synthesis is the best one as it is cost-effective, non-toxic in nature, simple at feasible conditions. In our study, we are fabricating silver nanoparticles by a single-step green synthesis method using the water extract of the leaves of the Vitex negundo plant. The plant is well known for its rich supply of biologically active compounds. The plant consists of flavonoids, polyphenols, terpenoids, and many more metabolite compounds that are used to prevent many diseases. These help as a capping agent and stabilizing agent in the process of forming silver nanoparticles from silver nitrate solution. Thus, fabricated silver nanoparticles are subjected to characterization techniques such as UV-Visible spectroscopy, FTIR, DLS, SEM with EDX, and XRD to determine silver nanoparticles' size, structure, and shape. Further, the antimicrobial activity of these silver nanoparticles is evaluated against four bacterial strains. Two of them are gram-positive, and the other two are gram-negative. The gram-positive bacteria, namely M. luteus and B. subtilis have shown good activity compared to gram-negative bacteria, namely E. coli and Salmonella. typhi.","PeriodicalId":18009,"journal":{"name":"Letters in Applied NanoBioScience","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86303566","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}

Ar-turmerone has various pharmacological effects, including antivenom, antidepressant, antiepileptic, antidermatophyte, antitumor, and antiplatelet activity. This research aimed to develop an isolation method of ar-turmerone from turmeric oleoresin using silica gel adsorbent, which is relatively low cost. Ar-turmerone was isolated by adsorption process using silica gel adsorbent and followed by elution process using a suitable solvent. The UV-visible spectrum of the isolated compounds showed a maximum wavelength at 237 nm. FTIR spectrum values were found at 2300 cm-1 and 2935 cm-1 (for aromatic C=C stretching), 1445 cm-1 and 1735 cm-1 (for C=O stretching), and 990 cm-1 and 1100 cm-1 (for C–H bending). GC-MS spectrum showed a main peak at a retention time of 12.884 minutes and a percent area of 27.74%, which was identified as ar-turmerone (molecular weight of 216). The optimum condition for the isolation of ar-turmerone from turmeric oleoresin using silica gel as adsorbent was the use of turmeric oleoresin:silica gel with a ratio of 1:3 without being affected by adsorption time. The optimum eluent for the elution process was 96% ethanol.","PeriodicalId":18009,"journal":{"name":"Letters in Applied NanoBioScience","volume":"239 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72918873","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}
