Effect of temperature on bean seed germination: vigor and isozyme expression
This research aimed to evaluate the physiological quality of seeds and isozyme expression in seedlings of bean’s genotypes under influence of germination temperatures. Seeds of Carioca, BRS Expedito and IPR Tuiuiú genotypes were subjected to five germination temperatures (15, 20, 25, 30 and 35 °C). Seeds were submitted to tests of germination, first count, germination speed index, cold test, isozyme expression and the total dry matter of seedlings. Germination was altered due to the different temperatures. As the temperature rose, seeds of IPR Tuiuiú and BRS Expedito had reduced germination. The increase on temperature significantly affected the germination speed index of the three genotypes, leading to a greater increase in the values of this attribute. Bands of esterase from the cold test showed less intensity compared to other tests. Due to the exposure to different temperatures, there are similarities between the number and intensity of bands on esterase, with lower enzyme expression at 30 and 35 °C, changes in the number and intensity of peroxidase expression at all temperatures, and practically none expression of the acid phosphatase enzyme in higher evaluated temperatures. Therefore, the seeds exhibit better performance when exposed to temperature of 30 °C compared to use of lower temperatures, while on temperatures above 30 °C isozymes expression is reduced for both genotypes.
Heamatologic Indices and Anti-Spermatogenic Effects of Dietary Supplemented Carica papaya seeds on Wister Rats
The continuous usage of indegienious plants as an intervention tool for diseases that affect both humans and animals is as old as orthodox medicine in its self in this study we evaluated the overall effect of carica papaya seeds extract on wister rats to determine its heamatoligic stimulatory effect and the anti-spermatic effect. A total of eighty rats where orally administered the various doses of the extract over a period of time and the heamatoligic and spermatologic parameters where analyzed. From the results obtained there was a slight stimulatory effects as the total white blood cell increased according to the varying doses of 100mg and 200mg respectively (6.56±0.38 and 6.96±0.10) with mean packed cell volume of 38.0±0.84 and 37.4±1.03 also noticeable is the slight rise in the Lymphocytes from the control group to the varying doses of exposure 70±2.06 and 68.6±1.12, the total Sperm cell count across the varying doses where 11.6×106 +0.5cells/mm3 and 11.3×106 +0.5cells/mm3 respectively. The above showed a a little marked increase the heamatologic parameters there was a slight increase in the lymphocyte although there was a marked decrease of sperm cell count from the control down the doses of exposure.
THE IMPACT OF MONETARY POLICY ON PRICE STABILITY IN NIGERIA
This study examines the impact of monetary policy on price stability in Nigeria from 1970 to 2014. The data obtained for the purpose of the study through Central Bank of Nigeria Statistical Bulletin were analysed using ordinary least square regression (OLS) model, unit root test and Johansen co-integration test. Consumer Price Index (CPI) is used as a proxy for general price level, which is the explained variable. Exchange rate and money supply were used as explanatory variables. The research also addressed various problems associated with monetary policies such as budget deficits, change in policy formulation, lack of enabling environment in the financial market and political instability. The result of the findings reveals that exchange rate and money supply actually influenced price stability in Nigeria both in the short-run and long-run. This is evidenced by 90% coefficient of determination and F-Statistics of 168.30 which is higher than the tabulated F-Statistics

Novel drug delivery systems for herbal drugs
Novel drug delivery systems(NDDS) for herbal drugs with poor water solubility have been expanding, almost exponentially, over thJHMR-CODEe past six years. The great advancement has been made for the technologies increasing the commercial potential of the herbal formulations by increasing the patient compliance and avoiding repeated administration of the formulation. There are varieties of novel herbal formulations like nanoparticles, matrix systems, solid dispersions, nanocapsules, liposomes, phytosomes, nanoemulsions, microemulsions, microsphere, micropellets, transferosomes, and ethosomes has been reported using bioactive and plant extracts. These formulations have remarkable advantages over conventional formulations of plant actives and extracts which include enhancement of solubility, bioavailability, therapeutic efficacy, enhancement of pharmacological activity, enhancement of stability, improved tissue macrophages distribution, sustained delivery, and protection from physical and chemical degradation. This review highlights the current status of the development of novel herbal formulations and applications of NDDS in the traditional medicine system to conflict more chronic diseases like asthma, diabetes, cancer and others.
Ethnobotanical importance and phytochemical analyses of some selected medicinal plants used in Ado-Ekiti Local Government Area, Ekiti State, Nigeria.
The study investigated the ethnobotanical importance, phytochemical and proximate compositions of some selected medicinal plants such as Enantia chlorantha (Annonaceae), Momordica charantia (Cucurbitaceae), Telfaria occidentalis (Cucurbitaceae) and Morinda lucida (Rubiaceae) in Ado-Ekiti Local Government Area of Ekiti State, Nigeria. The review of the folk knowledge of the plants revealed that they were used in treating ailments such as gastrointestinal infections, malaria fever, typhoid, dermatitis, ringworm, jaundice, dysentery and used as antiseptic, digestive stimulant, blood tonic and bloJHMR-CODEod booster. The qualitative screening of the plants revealed that all the plants contained a considerable amount of bio-active ingredients such as alkaloids, Saponins, tannins, flavonoids, cardiac glycosides, Terpenoids and total phenols. However, Momordica charantia has the highest number of alkaloids (20.68±0.27), Saponins (11.40±0.59) while Morinda lucida and Telfaria occidentalis have the lowest number of alkaloids (6.62±0.34) and Saponins (1.24±0.09). Similarly, Enantia chlorantha has the highest amount of flavonoids (15.56±0.00) and tannins (0.44±0.05). Morinda lucida stem bark has the lowest number of tannins (0.03±0.00) and flavonoids (0.94±0.00). Morinda lucida leaf has the highest amount of cardiac glycosides (0.07±0.03) while Morinda lucida stem bark and Momordica charantia does not have cardiac glycosides. Telfaria occidentalis has Terpenoids (0.09±0.00). Similarly, total phenols are high in Morinda lucida stem bark (0.58±0.00) while is low in Momordica charantia (0.21±0.00). The proximate composition showed that Telfaria occidentalis had the highest percentage of crude protein (31.49±1.32) and lowest percentage of crude fiber (9.08±0.27). Enantia chlorantha had the highest crude fat (5.17±0.24) and carbohydrates (50.31±1.56). Momordica charantia had the lowest percentage of total ash (2.67±0.16). Morinda lucida leaf had the highest percentages of moisture (10.10±0.14) and total ash (11.24±0.42) while Morinda lucida stem bark had the highest percentage of crude fiber (53.49±1.98) and lowest percentages of moisture (9.00±0.28), crude protein (5.70±0.14), crude fat (0.45±0.16) and carbohydrates (24.93±0.21).
Erwinia chrysanthemi, rhizospheric earthworms, sorghum, vermicompost
Bioagents colonized vermicompost can be a crucial alternative natural biological control of stalk rot diseases of sorghum because of the hazardous effects of agrochemicals on non-targeted organisms and soil health. To study the interaction among bioagents colonized vermicompost with stalk rot disease of sorghum caused by Erwinia chrysanthemi, and earthworms of rhizospheric soil, pre-plant soil application of bioagents colonized vermicompost @ 2.5 kg/4 m2 and chemicals viz. Blitox-50, Bleaching powder, Streptocyclin and Tetracyclin @ 2.5% were done under field conditions. In analysis of earthworm’s population dynamics, maximum numbers of young earthworms per plant rhizosphere were observed with vermicompost colonized isolate Th-2 followed by vermicompost alone and vermicompost colonized isolate Psf-24. However, minimum number of young earthworms per plant rhizosphere was obtained with Bleaching powder. Maximum seed germination was recorded with vermicompost colonized isolate Th-2 followed by Th-R, Th-14, and Psf-12. Maximum number of earthworm’s heap of cast per plant rhizosphere was obtained in plants treated with vermicompost colonized isolate Th-2 followed by Psf-19, Psf-12 and Psf-18. Significant increase in biomass yield of sorghum plants were observed among all the treatments. However, maximum biomass yield was observed with vermicompost colonized isolate Th-2 followed by Psf-24. Maximum reduction of disease severity was recorded with vermicompost colonized isolate Th-2 followed by Th-14, Th-R and Psf-3. Present investigation suggests the effect of bioagents colonized on the dramatic increase in earthworm’s population (young and adult), earthworm’s body length, sorghum plant biomass yield and reduction in stalk rot disease severity. Our experiments have shown that bioagents colonized vermicompost have considerable potential not only improving plant growth, suppression of stalk rot disease severity significantly but also increasing soil earthworms when used as pre-plant soil amendment.
