The study aims at evaluating the efficacy of different doses of powdered stem and leaf parts of Gmelina arborea on Dinoderus porcellus infesting yam chips in Jos metropolis. The experiment was conducted at the Entomology Laboratory of the Federal College of Forestry, Jos. Samples of infested yam chips and Gmelina arborea were collected in Jos metropolis. Newly emerged adult Dinoderus porcellus were exposed to the yam chips which were mixed with different levels of Gmelina arborea parts powder (0, 5, 10, 15 and 20 g). The setup was monitored for 120 hours and mortality recorded. The study was carried out in a randomized complete design with treatments replicated thrice. Data was analysed using analysis of variance at 1 and 5 percent confidence level and Duncan test was used to separate the means. The results obtained reveal significant differences at p value=0.05 and 0.01. The results reveal that in all the doses, an increase in the amount of the powder resulted in increased incidence of D. porcellus mortality. After 120 hours of exposure, 100 % mortality was recorded from either 15 or 20 g stem bark + leaf powder treatment. From the results obtained, the use of 15 g stem bark+leaf powder of Gmelina arborea could be effective in yam chips preservation which could in turn strengthen food security.

This study assessed the reproduction inhibition effects of Adansonai digitata plant part powders against D. porcellus affecting yam chips. Reproduction of adults D. porcellus were monitored with various doses of Adansonai digitata plant part powders and untreated yam chips as negative control (0 g). The finding of the research indicated that all treatments exhibited anti-reproduction potential and strong inhibition of D. porcellus emergence. The result of analysis of variance showed significant difference between the treated samples and the control (untreated) after 37 days. Adansonai digitata stem bark powders (10 g) was able to achieve no reproduction(0.00) after 37 days exposure. Based on this results, combining yam chips with 10 g of Adansonai digitata stem bark powders could ensure adequate management of D. porcellus destroying yam chips and yam tubers as a whole.

Abstract Background: Health extension workers are responsible for providing nutritional services like nutritional assessment and intervention for individuals who are identified as being at nutrition risk within their catchment area. Despite the Ethiopian government's effort to reduce the prevalence of maternal malnutrition through health extension workers, maternal underweight is still a significant public health problem in the country. Hence, this study aimed to identify the predictors of underweight among lactating mothers in Dangila woreda, Amhara Regional State, Ethiopia.Methods: An institution-based case-control study was conducted on 400 lactating women in three primary health care units of Dangila Woreda. A consecutive sampling method was used to select study participants. The data collectors were given appropriate training, and the principal investigator was continuously supervising the data collection process to ensure the accuracy and completeness of the information. A bivariable logistic regression was performed, and the variables with p-value <0.2 in bivariable logistic regression were entered to multivariable logistic regression to control the effect of confounding variables.Results: The present study showed no statistically significant difference between the cases and controls in the sociodemographic characteristics. Besides, most of the cases had inadequate (60.52%) levels of nutritional knowledge compared to the controls. Regarding household food security, the majority (93.88%) of the cases and controls (89.43%) had food security while only 6.12% of the cases and 10.57% of the controls had food insecurity. Age at first pregnancy (AOR=2.138, 95% CI: 1.134-4.031), breastfeeding age (AOR=2.486, 95 % CI: 1.281-4.823), and site of delivery (AOR=3.157, 95% CI: 1.407-7.084) were the predictors of underweight among lactating mothers.Conclusions: Age at first pregnancy, site of delivery, and breastfeeding age were the significant predictors of underweight in lactating mothers. Therefore, interventions like promoting institutional delivery, prevention of teenage pregnancy, and enhancing the intake of adequate nutrition during lactation should be taken.

This is a summary of the Young Water Professionals Seminar involving more than 50 young people from all over the world working with water. The presentations and following discussion were very lively and were about how subsidies and trade barriers imposed by the developed countries are influencing the income-generating capacity of millions of people in the developing world. Even though this is a very complex issue not easily resolved during the seminar it was also clear that there are some fundamental problems that need to be addressed. The importance of looking for solutions at different levels (i.e. local, regional, national) was highlighted as well as the policy of double standards, preaching free trade but only for the benefit of overdeveloped countries themselves. Further it was discussed how to achieve basin security through food security, and managing water for food security. The conclusion was that win-win solutions would be made if agricultural subsidies were to be completely removed.

Emergence of malaria parasite resistance to drugs has raised global public health concerns for a compelling need to develop improved malaria therapy. This study is a bio-guided isolation of triterpenoid antimalarial compounds from Terminalia mantaly. Methanol extract of the plant was subjected to column chromatography, and eluted with a ternary solvent system gradient-wise. Two compounds, 1 and 2, were isolated and characterised by spectroscopic data (IR, 1H and 13C NMR, COSY, HMQC, HMBC) and by comparison with literature. Isolated compounds were investigated for antimalarial property by spectrophotometric determination of inhibition of β-Hematin formation, absorbance taken at 405 nm. Results were analysed using Graghpad Prism® (6.0) and presented as mean IC50±SEM. Statistical significance, determined using Student’s t-test and one-way ANOVA, set at p-value of 0.05. Quantitative β-Hematin formation inhibitory activities gave IC50±SEM values of (compound 1; 4.434±0.47), (compound 2; 5.140±4.2) with (chloroquine; 0.335±0.1 mg/ml). Compound 1 was identified as 2,3,19,23-tetrahydroxyolean-12-en-28-oic acid glucopyranoside (arjunglucoside I), and compound2 as its aglycone, 2,3,19,23-tetrahydroxyolean-12-en-28-oic acid (arjungenin). This study provided credence for folkloric use of Terminalia mantaly to treat malaria, and this observed activity was probably due to these isolated triterpenoids.Keywords: β-Hematin, triterpenoids, nuclear magnetic resonance spectroscopy

Objective: To determine the frequency of the number of roots and root canals in a sample of 250 extracted maxillary first premolar teeth of patients visiting Peshawar Dental College and Hospital Khyber Pakhtunkhwa. Study Design: Cross Sectional. Setting: Department of Oral Biology, Peshawar Dental College and Hospital Khyber Pakhtunkhwa. Period: April 2016 to December 2016. Material & Methods: A total of 250 extracted human maxillary first premolars were collected from the Department of Oral & Maxillofacial Surgery, Peshawar Dental College, and Hospital Khyber Pakhtunkhwa. All teeth were visually inspected to count the number of roots. Subsequently, the access cavity was prepared, and pulp extirpated from each tooth. Endodontic explorer was used to locating the canal orifice(s) at the pulp chamber floor. Later the root canal orifices were injected with India ink to stain the canals. After that roots of teeth were sectioned at different levels to note down the number of canals. Data were analyzed using SPSS version 19. The statistical significance of the variations from mean values was considered significant if the p-value was less than 0.05. Results: Out of 250 maxillary first premolar teeth, 44.8% had one root, 40.4% had two separate and 12.8% had two fused roots. Three roots were seen in 2.0% teeth. Two root canals were present in the vast majority (70.4%), whereas one and three root canals were seen in 27.6% and 2.0% teeth, respectively. The correlation between the number of roots and root canals of maxillary first premolar teeth was highly significant. Conclusions: There was a high frequency of maxillary first premolars with two roots and two root canals.

Fresh pasta was formulated by replacing wheat semolina with 0, 5, 10, and 15 g/100 g (w/w) of Moringa oleifera L. leaf powder (MOLP). The samples (i.e., M0, M5, M10, and M15 as a function of the substitution level) were cooked by boiling. The changes in the phenolic bioaccessibility and the in vitro starch digestibility were considered. On the cooked-to-optimum samples, by means of ultra-high-performance liquid chromatography-quadrupole time-of-flight (UHPLC-QTOF) mass spectrometry, 152 polyphenols were putatively annotated with the greatest content recorded for M15 pasta, being 2.19 mg/g dry matter (p < 0.05). Multivariate statistics showed that stigmastanol ferulate (VIP score = 1.22) followed by isomeric forms of kaempferol (VIP scores = 1.19) and other phenolic acids (i.e., schottenol/sitosterol ferulate and 24-methylcholestanol ferulate) were the most affected compounds through the in vitro static digestion process. The inclusion of different levels of MOLP in the recipe increased the slowly digestible starch fractions and decreased the rapidly digestible starch fractions and the starch hydrolysis index of the cooked-to-optimum samples. The present results showed that MOLP could be considered a promising ingredient in fresh pasta formulation.

AbstractThe aim of this study was to analyse the general properties of the network of elite football teams that participated in UEFA Champions League 2015–2016. Analysis of variance of the general network measures between performances in competition was made. Moreover, the association between performance variables (goals, shots, and percentage of ball possession) and general network measures also was tested. The best sixteen teams that participated in UEFA Champions League 2015–2016 were analysed in a total of 109 official matches. Statistically significant differences between maximum stages in competition were found in total links (p = 0.003; ES = 0.087), network density (p = 0.003; ES = 0.088), and clustering coefficient (p = 0.007; ES = 0.078). Total links (r = 0.439; p = 0.001), network density (r = 0.433; p = 0.001) and clustering coefficient (r = 0.367; p = 0.001) had a moderate positive correlations with percentage of ball possession. This study revealed that teams that achieved the quarterfinals and finals had greater values of general network measures than the remaining teams, thus suggesting that higher values of homogeneity in network process may improve the success of the teams. Moderate correlations were found between ball possession and the general network measures suggesting that teams with more capacity to perform longer passing sequences may involve more players in a more homogeneity manner.
