To investigate the relationship between 25-hydroxyvitamin D (25-OHD) deficiency and hepatic encephalopathy (HE) in patients with chronic liver disease (CLD). METHODSA retrospective analysis of the results of 392 adult patients with chronic liver disease who were assessed for liver transplantation between 2006 and 2010 was undertaken. HE, severity of CLD, nutritional status and 25-OHD were analysed in patients assessed for liver transplantation between 2006 and 2010. Patients who presented with acute, fulminant or subacute disease, with a primary diagnosis of liver cancer, were assessed for re-transplantation or who did not have a 25-OHD measurement were excluded from the analysis. RESULTSOne hundred and sixty-five patients were included in this analysis. The mean age of all patients was 53 ± 8 years. Moderate to severe 25-OHD deficiency was identified in 49 patients of whom 36 had grade 2-3 HE compared with 13 patients who were not encephalopathic (P ≤ 0.0001). Mild 25-OHD deficiency was not associated with HE. There was a significant correlation between the severity of 25-OHD deficiency and the severity of liver disease (r = 0.39, P ≤ 0.0001) and disease severity and the presence of HE (P ≤ 0.0001). Importantly, individuals with 25-OHD deficiency were more likely to have a diagnosis of overt HE (OHE) at a significantly lower model for end stage liver disease (MELD) score than individuals without OHE (P ≤ 0.0001). This significant difference was observed with MELD scores from 10 to 38. CONCLUSION25-OHD deficiency was observed in the majority of patients with CLD and for the first time was found to be significantly worse in patients with OHE.

Objective: To analyse the phytochemical contents of leaf, stem bark and root of Jatropha curcas(J. curcas) in four solvent extracts and their proximate and mineral compositions. Methods: Standard analytical procedures were used for the determination of phytochemicals, proximate and mineral compositions of the leaf, stem bark and root extracts of J. curcas. Results: Results of the analysis showed the presence of polyphenols, flavonoids, alkaloids, cardiac glycosides, coumarins, saponins, terpenoids, steroids, triterpenoid saponins, carotenoids, phlobatannins and tannins in the leaf, stem bark and root of all the solvent extracts. Flavonoids were present in the highest amount in the ethyl acetate extracts of the leaf(7.35% ± 0.02%), stem bark(4.12% ± 0.01%) and root(3.35% ± 0.02%) followed by polyphenols in the methanol extracts of leaf(4.62% ± 0.02%), stem bark(2.77% ± 0.05%) and root(2.49% ± 0.02%). Poly-acetylated compounds were absent in all the solvent extracts of the leaf, stem bark and root. However, some anti-nutritional agents such as oxalates, phytates and cyanates were present in all the solvent extracts of the leaf, stem bark and root except the ethyl acetate. Phytates were high in the aqueous solvent of the leaf(6.12% ± 0.00%) but low in the stem bark(1.00% ± 0.05%) and root(0.89% ± 0.03%). Proximate composition showed appreciable amounts of total carbohydrate(36.33% ± 0.72%), crude protein(26.00% ± 0.47%) and reducing sugars(5.87% ± 0.14%) in the leaf, while crude fat was more in the stem bark(16.70% ± 0.30%). There was corresponding substantial energy in the leaf [(1 514.77 ± 20.87) kJ /100 g] and stem bark [(907.00 ± 8.52) kJ /100 g]. Moisture and ash contents of the leaf, stem bark and root were within acceptable limits for the use in drugs formulation. The mineral composition showed substantial amounts of important elements such as Fe, Ca, Na, Mg and Zn. Others were P, K and Se. Conclusions: The outcome of this study suggests that the leaf, stem bark

For eight decades, China and Canada have engaged in an increasingly rich and comprehensive collaboration in science, technology and innovation. Beginning with the personal engagement of some of the most prominent innovators in both countries in the 1930 s through the 1970 s, it was realized that China was building on millennia of leadership in innovation, while Canada was in the forefront of Western advances in key areas of research. As China began to open up to the West in the late 1970 s, Canada’s development agencies focused on helping China build capacity. University collaborations have also been strong, facilitated by the large Chinese diaspora in the Canadian research community. Canadian companies have had long-standing relations in China, and start-up incubators and accelerators in both countries have linkages with their counterparts. Over the years, Canadian and Chinese governments have deepened their S&T engagement, with an Agreement for Science and Technology Collaboration signed in 2007, and the Canada-China Joint Committee on S&T(CCJC) established to guide joint initiatives including a funded program for collaborative research. The most recent events were the inaugural meeting of the Sino-Canadian Innovation Dialogue held on October 29, 2018 and the CCJC meeting on October 30, 2018. The future is bright for continuing collaboration in the coming decades.

Increasing human activities around protected area pinpoint to looming degradation and alteration of the component of such areas, especially where adequate measures are not taken to forestall encroachment. The Oban division of the Cross River National Park is one of the oldest rainforests and has been identified as a biodiversity hotspot. However, communities settling around the park have been involved in some economic activities for their livelihood. Resource utilization at the edge of the park may alter the components of the park such as species diversity. Therefore this study is geared towards assessing the impact of human encroachment and the concomitant impact on the distribution of species within the park. The study adopted participatory research methods which included Focus Group Discussion and participatory mapping as well as a plot based survey which involved the laying of sample plots within two zones of the park designated as areas bounded by cultivated land and areas bounded by fallow. Three 40 m × 40 m square plots are laid along a 320 meter transect measured from the boundary of the park at each buffer zone. The plots are separated by 100 m gap. From the result obtained, it is discovered that Musanga cercropoides dominates the outer plots of the cultivated zones and fallow zones comprising 20.2 and 21.5 percent respectively while Terminalia ivorensis dominates the middle and inner areas of the park. Moreover the composition of species decreases inward to the inner part of the park. Diversity index decreases in the order of 2.566 < 2.348 < 2.163 at the cultivated zones and 2.443 < 2.376 < 2.366 at the fallow zones. It is concluded that human activities close to the park alters the species composition of the park. Hence, it’s recommended that adequate alternatives livelihood and incentive be provided to support zone communities to reduce their dependents on the edge of the park.
