This work aims to evaluate the antidepressant and anxiolytic activities of the dichloromethane/methanol extract of CA trunk bark in a chronic unpredictable stress-induced depression (UCMS) model in mice. After exposure of mice to UCMS for 42 days, anhedonia was assessed using the sucrose preference test, antidepressant effects by the forced swim and caudal suspension tests, anxiolytic effects by the light/dark compartment (LDB) and open arena (OF) tests. Oxidative stress parameters Malondialdehyde (MDA), Superoxide Dismutase (SOD), Catalase (CAT), and Reduced Glutathione (GSH) were assessed. The results showed that multiple administrations of C. adansonii extract (150 and 300 mg/kg, resulted in a significant increase from 38.5% to 64.9% (p<0.001) in sucrose intake and a decrease from 47 seconds to 14 seconds in the immobility time in the forced swim test compared to the UCMS group. The extract significantly (p<0.001) reversed the time spent in the dark box at 150 mg/kg, and the number of groomings at 150 and 300 mg/kg compared to the UCMS group in the LDB and OF test. There was also a significant (p<0.001) improvement in SOD, GSH, and a reversal of MDA. The extract of CA improved symptoms of depression and anxiety in mice treated with different dose. The effects observed would be due to the presence in the extract of polyphenols such as flavonoids. These effects would justify the use of this extract in traditional medicine.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45458096","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}

Therefore, this study investigated the adaptive features of each weed in competition, with a further determination of seedling recruitment from the soil seed bank of plots invaded by T. rotundifolia. Field sampling was carried out in 10 plots: T. rotundifolia invaded plots and low or uninvaded plots in co-existing with other plants using 10 m x 10 m quadrats. The readily germinable seed species composition and the Sorensen index of similarity between the seed bank and their above ground vegetation were determined. Competition Series Experiment was also conducted for the two plants. Mariscus alternifolius (227) and Oldenlandia corymbosa (358) were the most abundant species in the seed bank while T. rotundifolia recruited 25 individuals. Low similarity index existed between the seed bank and the standing vegetation of the invaded and uninvaded plots. T. rotundifolia had improved growth in heteroculture with C. odorata over when in monoculture. However, a reduction in growth of C. odorata occurred when in competitive association with T. rotundifolia compared to when in monoculture. T. rotundifolia had competitive advantage over C. odorata.

The aim of the present study was to identify the elemental content and to determine antibacterial potentiality of Belosynapsis vivipara (Bv) ethanol leaves extract. Shade dried powdered material of BV leaves was estimated for elemental content using Atomic Absorption Spectrophotometer (AAS) followed by extraction by ethanol solvent (80%) in Soxhlet apparatus for 13 hrs at 45 °C. Extract was further used for anti-bacterial screening. In vitro antibacterial studies on the leaf extracts (25, 50 and 75 µg/ml) were carried out on medically important micro-organisms of Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa (Gram negative) and Staphylococcus aureus, Bacillus subtilis and Streptococcus pyogenes (Gram positive) against standard Ampicillin (25 µg/ml). The powdered drug showed the presence of zinc, and Copper in high amount less content of iron, whereas very less content of Nickel and Cobalt and absence of lead, mercury, arsenic and cadmium. The preliminary phytochemical screening revealed the presence of chemical constituents like alkaloids, flavonoids, phyto sterols, saponins and phenolics. Furthermore, ethanol leaves extract of BV showed broad spectrum antibacterial efficacy against both Gram positive and Gram-negative microorganism along with the dose dependency effects. Antibacterial activity was correlated with the elements and showed positive correlation. Finally, Belosynapsis vivipara (Dalzell) C.E.C. Fisch. leaves were established as an effective source against strong bacterial infection.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45057107","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}

Mill.) belongs to the Cactaceae family and it’s used in traditional folk medicine in treating a number of diseases and conditions. Due to the remarkable biological activity and to the bioactive (phytochemicals) compounds of O. ficus-indica, it becomes the aim of many research studies. The current study aimed to evaluate the analgesic activity of various solvent fractions (aqueous and ethanol) prepared from the O. ficus-indica flowers. The centrally analgesic potential was evaluated using tail flick latency in tail immersion and hot plate methods in mice. Morphine was used as a positive control at a dose of 3 mg kg-1, s.c.. Intra-peritoneal administration of the aqueous extract of O. ficus-indica flowers at the highest dose did not produce any toxicity symptoms, thus the median lethal dose (LD50) was estimated to be greater than 2,500 mg kg-1. The results of the pain behavior evaluation according to the gender approach of mice showed that the pain tolerance threshold is high in males compared to females. We found that various plant extracts at doses of 300, 500, and 1,000 mg kg-1 i.p., displayed significant and dose-dependent protective effects (p < 0.01, p < 0.001, and p < 0.0001) as measured by increased latency time compared to vehicle control. The maximum anti-nociceptive effect was with the ethanol extract (71%) at 60 minutes at a dose of 1,000 mg kg-1, which was equivalent to the effect of morphine (70%). The results suggested that O. ficus-indica might possess significant analgesic effects, supporting the use of this plant in traditional medicine.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44726467","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 11 isolates, 6 were siderophore producers as they produced orange halos on CAS agar. Isolated bacteria were examined for their hydroxamate, catechol, and carboxylate type of siderophore, and it revealed that all produced hydroxamate siderophore. Among all the isolates, a potential bacterium was selected for further studies and identified by the biochemical test as Pseudomonas sp. MT. Temporal effect on growth and siderophore production revealed that both were higher at 24 hrs of incubation and remained active up to 8 days and then after the decline. Siderophore was partially purified and chemically characterized by FTIR. A particle size analyzer measured the particle size of the siderophore and showed 91.36 nm in size. The siderophore producer and non-producer were examined for their ability to uptake iron by providing external siderophores, which gave positive results.

Intercropping forage legumes with cereal crops may be a way of providing ecological services such as providing N for companion or following crops by biological N fixation. To determine the effect of biological, chemical, and organic fertilization on the quality and quantity of ten different wheat cultivars, an experiment was conducted during two successive growing seasons. The three experimental factors (F1, F2, F3) were: mix cropping with Persian clover (Trifolium resupinatum L.) (F1: biological N fixation, as control); chemical nitrogen fertilizer (F2: 100 kg ha-1, urea), and organic cow manure (F3: 40 t ha-1). The vegetative growth parameters improved by F1 and F2 treatments. The F2 had the highest values of spikelet and seed number per spike, 1000-grain weight, and seed yield, followed by F1. The cv. ‘Kabul-13’ was the best among all tested cultivars in terms of almost all reproductive parameters. The highest seed yield was obtained by F2 ‘Kabul-13’ (8.02 t ha-1), and F1 ‘Kabul-13’ (7.26 t ha-1). By considering seed yield, ‘Chont-1’ and ‘Kabul-13’ were more suitable to be intercropped with clover. The effect of experimental factors was not significant on seed potassium and phosphorus contents, while percentage of seed protein improved by F3 (13%), and ‘Mugawim’ (13.59%). The highest protein yield was gained by F2 and F1 (820 and 650 kg ha-1) and also by ‘Kabul-13’ (850 kg ha-1). Overall, mixed cropping of wheat and clover can be suggested as a possible alternative for nutrients providing in wheat production in low input agro-ecosystems.","PeriodicalId":19353,"journal":{"name":"Notulae Scientia Biologicae","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49105490","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}

Faecal samples were collected and subjected to the formalin-ethyl acetate (formol-ether) sedimentation technique. Sediments from the formol-ether sedimentation method were used for the modified Ziehl-Neelsen staining technique. The Microsoft Excel (2016) spreadsheet and the Statistical Package for the Social Sciences (SPSS, Chicago, Illinois, USA) for Windows version 22.0 were used for the data analysis. Of the cattle sampled, 99 were positive for the enteric protozoan (29.73%; 95% confidence interval (CI) = 25.07–34.85). There was no distinct pattern in the monthly prevalence of Cryptosporidium infection in cattle. Breeds of cattle, physiological status, and seasons were statistically associated with the prevalence of Cryptosporidium species in cattle. There is a need to educate pastoralists on the control and preventive measures of this enteric protozoan to improve the economy of the cattle industry and prevent possible transmission to humans in Kwara State and Nigeria in general.
