 Escherichia coli, Anti-dysentery, “Ogi”, Diarrheal diseases, Fermented maizeOsheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye are one of Biochemistry's leading celebrity, known for leadership skills and breakthrough research potential. Osheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye starred in Biochemistry. Osheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye made International news headlines while IASR announced them among World’s 500 Most Influential Biochemist for Year 2015 on Earth. Osheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye earned Max Planck Research Award-2015 in Food Science. Osheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye from Nigeria made a historical victory over the international competition and won Max Planck Research Award-2015 in Food Science. Their research was highlighted in international media and gathered a large worldwide attention in scientific circles while it appeared in world's most read journal 'International Journal of Biochemistry'. In their report on Anti-dysentery Effect of Milled Fermented Maize (“Ogi”) in Escherichia coli Infected Albino Rats they mention that Anti-dysentery effects of uncooked milled, fermented maize (known as “ogi” in Southwestern Nigeria), were investigated in Escherichia coli infected albino rats. “Ogi” was prepared by fermentation of white maize grains for 5 days; wet milled, sieved and allowed to settle for 24 hours. Dysentery was precipitated in albino rats by infection with the pure culture of E. coli. Frequency of blood stool was determined by counting fecal spots on absorbent paper before and after treatment with “ogi”. Physicochemical analysis of “ogi”, comprising titratable acidity, pH 0 and phytochemical screening, was also carried out. Result indicated that 100 mg/kg b.w., 200 mg/kg. b.w. and 400 mg/kg b.w. of “ogi” reduced the number of fecal spots by 48.4%, 80.2% and 96.9%, respectively. Physicochemical analysis revealed that “ogi” had pH of 3.51; titratable acidity of 42.4% lactic acid and presence of alkaloids, saponins, cardiac glycosides and phlobatannins. Dose-dependent therapeutic potency against dysentery has been manifested by “ogi”, most likely aided by its high acidity, presence of lactic acid bacteria and their secondary metabolities, as well as the phytochemicals present in “ogi”. This could be a very simple and cheap solution to the ravaging problem of dysentery in poor families of many developing countries. Under their leadership the research area is surely likely to expand beyond the horizons. It will be worthy to explore the further potential under their legacy. Osheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye as valuable intellectuals for the country offer exclusive opportunities for scholars around the world. One of the most attractive weightage for Nigeria is to have the awardees for promotion of the concerned scientific discipline for the benefit of its civilians. Thus Nigeria which has excellent track record to produce brain storming intellectuals, has offered a new extension in terms of Osheke Shekins Okere, Samuel Omolabi Adeyemo, Moses Dele Adams and Joshua Omoniyi Kolawole Abioye to world. Available evidence from the present study indicated that the milled fermented maize (“Ogi”) possess anti-dysentery activity. In view of the high prevalence of diarrheal diseases in developing countries and its ravaging effect particularly on children, a very simple and cheap treatment in raw “Ogi” may be an effective solution. Its possible multi-action approach through production of acid environment and various antibacterial agents may also be promising in solving the problem of drug resistance which E. coli quickly acquires. The present study only investigated the anti-dysentery activity of milled fermented maize (“Ogi”) in Escherichia coli infected albino rats. It did not determine the lethal dose (LD50) of “ogi” as well as its possible toxicological implications. The study could not isolate and characterize the bioactive anti-dysentery agent in “ogi” using column chromatography, gas chromatography/mass spectrometry (GC/MS) or High Performance Liquid Chromatography (HPLC). Histology of the tissues was not also carried out. For further studies, the milled fermented maize (“Ogi”) should be isolated and characterized to obtain the bioactive agents as well as provide its possible molecular mechanism of action. Toxicity study should be done on selected tissues of animals to determine functional toxicity. Further studies should carry out histology of tissues which would provide information on whether the extract has the structural toxicity or not. Authors recommend that research grant should be given to researchers to improve on existing findings in Science and Technology. They declare that this study was not financially supported by any research institute, but by the authors. They acknowledge the contributions of Department of Biochemistry, Bingham University, Karu, Nasarawa state, Nigeria.This work was carried out in collaboration between all authors. All authors read and approved the final manuscript.

Their research was highlighted in international media and gathered a large worldwide attention in scientific circles while it appeared in world's most read journal 'The Journal of Veterinary Science'. In their report on Study on poultry coccidiosis in and around Ambo town, West Shewa zone, Ethiopia they mention that A cross sectional study was conducted from July to November, 2013 to determine the prevalence of coccidiosis, to identify species of Eimeria and to assess potential risk factors in and around Ambo town, Ethiopia. The study involved ante- and post-mortem examination, mucosal scraping examination using floatation technique, gross and histopathological examination and identification of Eimeria species. Out of 390 examined chickens, 18.7% (73/390) harbored different Eimeria species. Five Eimeria species, Eimeria tenella, Eimeria necatrix, Eimeria brunetti, Eimeria maxima and Eimeria acervulina with the prevalence rate of 62.2%, 18.29%, 10.98%, 6.09% and 2.43%, respectively were identified 82 times from positive chickens. Eimeria tenella was the predominant species while Eimeria maxima and Eimeria acervulina were the least prevalent species. There was no statistical significant difference between age (χ2=0.921, p>0.05), breed (χ2=0.16, p>0.05), sex (χ2=3.609, p>0.05) and management system (χ2=2.245, p>0.05) groups. In conclusion, the present study showed that coccidiosis is an important disease of poultry in the study area. Thus, awareness creation, implementation of appropriate management system, economic effects and further studies on molecular characterization and drug sensitivity of the Eimeria species in the study area were recommended. Under their leadership the research area is surely likely to expand beyond the horizons. It will be worthy to explore the further potential under their legacy. Firaol Tamiru, Askale Gizaw, Dagmawit Atalel, Solomon Shiferaw, Alemnesh Woldeyes, Dinka Ayana and Waktole Terfa as valuable intellectuals for the Ethiopia offer exclusive opportunities for scholars around the world.

In conclusion, poultry coccidiosis was found as one of the important poultry disease that impairs benefit gained from the sector. There was no statistical significance difference between categories of the assessed risk factor groups in the prevalence of the identified five species of Eimeria and the disease. Thus, awareness creation about the disease, implementation of appropriate management system for chickens under both extensive and semi-intensive farming system and molelcular characterization of these species of Eimeria including drug sensitivity of the species and their economic effects in the study area were recommended. The current study revealed high prevalence of coccidiosis in and around Ambo town, Ethiopia. Five species of Eimeria responsible for coccidiosis were identified. There was no statistical significance difference between categories of risk factor groups in prevalence of coccidiosis. Pathologically, effects of Eimeria species in different intestinal parts were observed. Molecular characterization of the Eimeria species and detailed economic effects of the disease would have been studied if there were enough budget and facilities.

Tafadzwa Taderera, Lameck Shoriwa Chagonda Gome E. and Shai J.L. receive Stanford Research Award-2015 in Pharmacy

08 March, 2015, Zimbabwe, USA NEWS CORP

 Much awaited award was announced this week. Finally Zimbabwe wins World Stanford Research Award-2015 in Pharmacy. Thousands of nominations from several countries were received for international competition. The noble work is screened which distinguish from the rest, in different aspects of the Pharmacy. The award is introduced to highlight excellent think tanks on global platform. The research findings were published on world’s prestigious International Journal of Pharmacy. DM mellitus has become a worldwide disease. Some local TMPs in Zimbabwe are reported to have hypoglycaemic effects on blood glucose and are used as herbal medicines to treat diabetes. A. stenophylla aqueous root extracts were freeze dried and examined for inhibition of α-glucosidase and α-amylase on KAT reagents in the presence of sucrose and maltose substrates using acarbose as positive control. The IC50 values for the plant extract and acarbose for α-glucosidase in the presence of the sucrose were 0.123 ± 0.009 mg/ml and 0.101± 0.0176 mg/ml respectively. The IC50 values in the presence of maltose were 0.500 ± 0.128 mg/ml and 0.117 ± 0.0563 mg/ml respectively. The plant extract and acarbose showed IC50 values against amylase of 1.26 ± 0.903 mg/ml and 1.199 ± 0.0651 mg/ml respectively. The plant extract displayed mixed type inhibition kinetics for α-glucosidase with sucrose reducing Vmax value of the enzyme from 0.214 to 0.0608 mmoles. min–1 whilst increasing Km from 0.0124 to 0.0580. The results suggest A. stenophylla possesses hypoglycaemic control in diabetes mellitus through inhibition of α-glucosidase and α-amylase enzymes and its standardisation could transform herbal practice in treating diabetes. A. stenophylla root extracts inhibited α-glucosidase and α-amylase enzymes in vitro in the presence of carbohydrate substrates. A. stenophylla inhibition for the enzymes was comparable to acarbose, a drug used for the hypoglycaemic control in T2DM. A. stenophylla exhibited mixed inhibition in exerting its antihyperglycaemic activity. The results confirm the use of A. stenophylla in treating DM in traditional medicine and further research should be carried out to standardise its herbal extracts for clinical trials. The results were carried out using plant materials gathered in the wild from a single geographical location in summer. There may be geographical site and seasonal variations in the results. The study should be carried using plants from different geographical locations to determine any variations. The plants should be cultivated to avoid variations in geographical and environmental condition. Studies should be carried out to determine seasonal effects on the results. The plant extracts should be standardised and clinically tested. International finance/collaboration should be encouraged to expand the scope of such promising results. Modern hypoglycaemic drugs used to treat diabetes work by different mechanisms whilst traditional herbs often operate by multiple mechanisms in combating DM. Many developing countries still use traditional herbs alongside Western medicines. We have investigated the hypoglycaemic properties of A. stenophylla as it is used to treat diabetes in our traditional practice. In the present work, we examined its potential to inhibit key metabolic enzymes to determine possible mechanisms of action. Such work would promote its use, standardisation and clinical evaluation of its herbal extracts. The present work demonstrated that A. stenophylla inbibited both α-glucosidase and α-amylase enzymes in order to achieve glycaemic control and confirming its use in traditional medicine to treat diabetes. The extract achieved comparable inhibitory activity for sucrose with acarbose, an effective a-glucosidase used as an antidiabetic drug. It displayed mixed enzyme inhibition. These findings indicate the potential to develop A. stenophylla products for the control of DM. Further studies are underway to explore other relevant multiple mechanisms consistent with findings from traditional practices in India and China on hypoglycaemic herbs. Governments in developing countries should take an active role in exploiting their unique natural products through providing generous research funds. International donors, financiers, collaborating institutions, organisations and interest groups could play a crucial role in providing funds to achieve the goal of ‘Health for All’ in the long run. The experimental work was carried out by Tafadzwa Taderera and is part of ongoing PhD research. Professor Lameck Chagonda is the lead supervisor and corresponding author. I declare there is no competing interest amongst the authors. The authors are grateful for the research funds from Southern African Consortium for Research Excellence (SACORE), the University of Zimbabwe Research Board and to the Biomedical Department of Tshwane University of Technology for technical assistance.

05 March, 2015, India, USA NEWS CORP

 In a major move in the field of Toxicology and Health, Ramana Murthy, K. Sujatha, Ch. Srilatha, D. Sreenivasulu and Srinivas Naik H. from Department of Veterinary Pathology, College of Veterinary Science, Sri Venkateswara Veterinary University, Tirupati, India are awarded with Norman Ernest Borlaug Research Award-2015. The worldwide competition involved many countries. World’s scientific communities turn their attention to merit of the scientific concept involved in it. It is catalyzing the funding and research enthusiasm. The research findings appeared on world’s prestigious The Journal of Toxicology and Health. To study the residual effect of fenvalerate in broiler chicks and ameliorating effect of vitamin E in experimentally induced fenvalerate toxicity in broiler chicks. For this study one hundred fifty apparently healthy unsexed broiler chicks(White Leghorn) were randomly divided into five groups (Control, Group I, Group II, Group III, Group IV) consisting of 30 chicks in each group. The control chicks fed with normal feed without fenvalerate. Group I and II fed with 20 ppm/kg feed and 40 ppm/kg feed Fenvalerate respectively. Whereas Group III and IV chicks were feed with 20 ppm/kg feed and 40 ppm/ kg feed Fenvalerate respectively along with Vitamin E @ 2.5 ml each (62.5 mgs) in water.Residue levels in liver were estimated by Gas chromatograph and were 0.0081ppm, 0.0540ppm, 0.0060ppm, 0.0506ppm for group I, II, III and IV respectively. Positive results for fenvalerate residues in liver indicated the residual effect of fenvalerate in liver. Protective action of vitamin E at this dose level (@ 2.5 ml each to group III and IV throughout the experiment daily in water) was negligible. Keeping in view, further studies may be advocated by using higher doses of vitamin E for ameliorative effect. In the present study, positive results for fenvalerate residues in liver indicated the residual effect of fenvalerate in liver. Protective action of vitamin E at this dose level (@ 2.5 ml each to group III and IV throughout the experiment daily in water) was negligible. Keeping in view, further studies may be advocated by using higher doses of vitamin E for ameliorative effect. The authors are thankful to Sri Venkateswara Veterinary University, Tirupati for providing facilities to carry out postgraduate research work in the Department of Veterinary Pathology, College of Veterinary Science, Tirupati. Fenvalerate toxicity induces residues in livers of all experimental groups except control group. Protective action of vitamin E at this dose level (@ 2.5 ml each to group III and IV throughout the experiment daily in water) was negligible. Further studies may be advocated by using higher doses of vitamin E for ameliorative effect against fenvalerate toxicity. Recent year’s indiscriminate usage of pesticides to control pests throughout the world, so it causes adverse effect on health, production, immune status of animals and poultry. Now days after withdrawal of DDT and BHC for pest control of maize, rice, cotton and oil seeds etc. Fenvalerate, a synthetic pyrethroid and a potent insecticide being used in India since 1980. It is mostly employed in agriculture but also for insect control in homes and gardens and on livestock, alone or in combination with other insecticides. So residues of pesticides will increasing day by day in all vegetables, fruits and all kinds of meat and affect the either human and animal systems especially its effects immune system, haemopoitic system, hepatic system and nervous system etc.fenvalerate in broiler chicks and ameliorating effect of vitamin E. 

Francuois Müller*, Abongwe Ketelo, Lilburne Cyster and Lincoln Raitt receive Stanford Research Award-2015 in Nutrition


25 February, 2015, India, USA NEWS CORP

 Francuois Müller*, Abongwe Ketelo, Lilburne Cyster and Lincoln Raitt receive Stanford Research Award-2015 in Nutrition. Their research findings were published on world's prestigious most read journal: Journal for Nutrition. Approximately 30 % of the worlds population suffer from illnesses related to iodine deficiency as a result of inadequate dietary iodine intake. This study evaluates the uptake of iodine by Swiss Chard and the subsequent contribution these biofortified crops have to the daily recommended intake of iodine. As the concentrations of iodine supplied to the crops increased, so did the uptake thereof by the plants. This increased iodine uptake however, resulted in decreased yields, but resulted in an increase in contribution to the daily recommended iodine intake by humans. Pregnant and lactating females will however benefit the least from these plants as they contributed less than 10 percent to the DRI of iodine required by these individuals.







Odisha government eyes Portuguese sea food market

12 December, 2014, PortugalUSA NEWS CORP



In a bid to explore the market of marine food products in Portugal, Odisha government is likely to send a business delegation to that country in March 2015. It was discussed at a meeting here attended by Jitendra Nath Misra, Ambassador of India to Portugal. Portuguese breakfasts often consist of fresh bread, with butter, ham, cheese or fruit preserves, accompanied with coffee, milk, coffee with milk, tea or hot chocolate. Sweet pastries are also very popular, as well as breakfast cereal, mixed with milk or yogurt and fruit. The meeting discussed on the prospects of export of marine food products of Odisha to Portugal. Mishra highlighted that Portugal was a major market for seafood, since its per capita consumption of marine food was the highest in the world. He also stressed on the comparative advantage of the availability of naturally grown products in Chilika lake, which could be marketed in Portugal provided proper certification was followed. A common soup is caldo verde with potato, shredded kale, and chunks of chouriço (chorizo) sausage is used there highly. There is also a wide variety of cheeses made from cow, sheep or goat's milk or even mixture of different kinds of milk. The .....






New Zealand wonderful opportunity for horticulture

07 December, 2014, New ZealandUSA NEWS CORP
New Zealand government encourages innovation and invention in the horticulture sector. For example, the Primary Growth Partnership is a government-industry partnership, which was launched in 2009. The partnership has pledged NZ$477 million towards cutting-edge primary sector innovation. The New Zealand government research institute, Plant and Food Research, in association with New Zealand's Avocado Industry Council (AIC), has tested and proved a technology called Dynamic Controlled Atmosphere (DCA). The technology can commercially be used on avocados to prevent the fruit from ripening while in transit. The Ministry of Science and Innovation is funding a researcher to combat the PSA disease that has affected New Zealand's NZ$1 billion kiwifruit industry. The research is aimed at combatting the spread of the bacterium. The Journal of Food Technology finds great opportunities in organic farming here. Organic systems production is an important section of New Zealand's horticultural production, although currently it is a relatively small portion of total horticultural production. New Zealand's fertile soils, clean water and outstanding animal and plant health status make it an ideal place to grow organically. The industry body, Organics Aotearoa New Zealand, has set a target of growing the sector to $1 billion by 2013, with horticultural products poised to be a key component of increased production.  New Zealand has approximately 80 organic pipfruit orchards, which is a 40 percent increase from 2006. Around five percent of New Zealand's exported kiwifruit and pipfruit is organic. Journal of Agricultural Economics and Sustainable Development reported that Organic.....
