The phytochemicals, vitamins, minerals, amino acid and proximate compositions of the leaf extract of Justicia carnea were determined using standard methods. Results of the quantitative phytochemical analyses on the leaves of Justicia carnea recorded appreciable presence of flavonoids, alkaloids, saponins, tannins, cyanogenic glycosides, oxalate, and phytate using GC-FID. Ribalinidine with 42.08±0.03 mg/kg was the highest alkaloid, Flavan -3-ol was 21.18±0.02 mg/kg, presented the highest amount of flavonoids, and phytate with 25.69±0.07 mg/kg as the highest antinutrient. Analysis of Justicia carnea leaves recorded iron (8.61mg/kg) as the major elemental content followed by potassium (5.29±0.11mg/kg). The concentrations of vitamins in Justicia carnea leaves showed vitamin C, with the highest value of (232.32±12.26 mg/100g) followed by Vitamin A (22.16±2.12 mg/kg). The results of proximate composition on Justicia carnea leaves showed a high concentration of carbohydrate (60.35±3.05%) and appreciable amounts of ash (15.02±1.01%), fibre (9.29±0.93%), protein (8.40±0.41%), and low amount of lipid (1.50±0.09%). The amino acid results showed the presence of both essential and non-essential amino acids with their concentrations in increasing and decreasing orders. These results obtained showed that leaves of Justicia carnea may serve as rich source of natural antioxidants, this may be attributed to its rich phytochemicals, nutrients and vitamin compositions and could be recommended as a potential source of useful bioactive constituents as vegetable supplement and has no toxic effect and as an effective hematinic supplement when prepared adequately.","PeriodicalId":12808,"journal":{"name":"GSC Biological and Pharmaceutical Sciences","volume":"33 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140418773","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}

The extract of B. flabellifer is proven to have cytotoxic effects and can inhibit the growth of several types of cancer cells such as HeLa cell lines. Objective: To determine the cytotoxicity effect of extract of B. flabellifer L. fruit seed coat against HSC-3 cell line. Methods: Laboratory experimental research was conducted using HSC-3 cell lines treated with B. flabellifer L. fruit seed coat extract at concentrations of 93.75 µg/mL, 187.5 µg/mL, 375 µg/mL, 750 µg/mL, and 1,500 µg/mL, negative control DMEM-FBS 20%, and positive control anti cancer drugs Doxorubicin 3 µM. HSC-3 cell line cytotoxicity assay was performed using CCK-8 reagent. Micro plate reader at 450 nm wavelength was used to determine the viability of HSC-3 cell lines by measuring the optical density of formazan. Results: B. flabellifer fruit L. seed coat extract was able to reduce viability and was cytotoxic to HSC-3 cell lines at concentrations of 93.75 µg/mL, 187.5 µg/mL, 375 µg/mL, 750 µg/mL, and 1,500 µg/mL, with an IC50 value of 141.9 µg/mL.

These parasitic diseases causes many mortality in small ruminant breeding therefore considerable economic losses. Thus, the present study was carried out with the aim of evaluating the in vitro anthelmintic effectiveness of Azadiracta indica (A. indica) leaves on two life stages of Haemonchus contortus (H. contortus): eggs and adult worms. To do this, an aqueous and ethanolic extract of A. indica leaves was carried out. From these extracts, five (5) increasing concentrations were performed: 1.25; 2.5; 5 ; 10 and 20 mg/mL and three (3) controls (distilled water, DMSO 2% and albendazol). These concentrations were brought into contact with i) eggs for Eggs Hatch inhibition Assay st (EHA) and ii) Adult Mortality Test (AMT). Three replicates were performed for each experimental preparations. In vitro observations showed that ethanolic extract of A. indica caused high mortalities (p < 0.0001) ranging from 44.44 to 100% at 2 hours and 6 hours of exposure respectively at 20 mg/mL. In the same time interval, albendazol showed 100% of mortality in H. contortus. For EHA, the inhibition rate varied from 18% to 85% for the aqueous extract and from 54% to 93% for ethanolic extract.

The first subgroup consists of the patients with positive FISH probes for hyperdiploidy myeloma and/or 14q34 rearrangements and 1q25/1p36, while the second one consists of patients, negative for all the three probes listed above. A comparison between the demographic, laboratory data and the ISS (International Staging System) stage of the two subgroups has been made.

This evaluation is part of an overall approach to verifying the methods used in the central laboratory of the Mohammed VI University Hospital of Oujda , with a view to compiling an accreditation file in accordance with the requirements of standard NF ISO 15189. Materials and methods: The working methodology adapted by our study is based on the recommendations of the protocol of the COFRAC accreditation technical guide SH GTA 04. Verification involved assessing the repeatability and reproducibility of Alinity ci . Results: The results obtained for the various haptoglobin assay verification criteria show satisfactory repeatability for all three levels, with CV1=1.10%, CV2=0.78% and CV3=1.07% respectively. intra-laboratory reproducibility was satisfactory for all three levels, with CV1=1.79%, CV2= 4.2% and CV3=1.62% respectively. Discussion: Verification of an analytical method is an essential step in guaranteeing that the result obtained is as close as possible to the reference value of a sample. Comparing our results with the CV adopted by the SFBC, we can see that the results are in line with and below the tolerated limits. Conclusion: We can therefore conclude that the Abbott Alinity ci system meets the requirements set by scientific societies for the determination of haptoglobin.","PeriodicalId":12808,"journal":{"name":"GSC Biological and Pharmaceutical Sciences","volume":"9 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139591593","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}
