Effect of groundnut flour substitution on yield, quality and storage stability of kilishii – a Nigerian indigenous dried meat product
VN Mgbemere, MA Akpapunam, JO Igene
African Journal of Food, Agriculture, Nutrition and Development , 2011,
Abstract: Kilishi, a traditionally sun-dried roasted meat product usually produced using raw meat, Tunkusa (a locally defatted groundnut cake paste), in combination with spices and condiments in the mix was produced after substitution with conventional defatted groundnut flour. This study was undertaken to establish the potential use of conventional defatted groundnut flour in place of Tunkusa in making a better quality and shelf - stable Kilishi. The yield, quality and storage stability of the product were evaluated using standard assay techniques. Yield was estimated as the ratio of weight of Kilishi over the fresh beef. Quality was measured in terms of proximate composition which included protein, fat, carbohydrate, fibre and ash contents, and the amount of calorie obtained from the Kilishi was calculated based on these constituents. Sensory quality attributes were also measured in terms of colour/appearance, flavour, crispiness, texture and overall acceptability. Microbial counts such as total plate, yeast and mould and coliform were measured. Storage stability was evaluated in terms of thiobarbituric acid (TBA), free fatty acid (FFA) and Peroxide value (PV) values prior and following storage in ambient (25-32°C) or refrigerator (7±1°C) for 12 weeks. Yield of the Kilishi (GFK) produced from conventional defatted groundnut flour ingredients was 87.3% compared to 83.7% of traditionally defatted groundnut cake (Tunkusa) Kilishi (TK) (control). The GFK had 12.1% moisture, 51.8% protein, 13.4% fat, 5.1% ash, 2.8% crude fibre and 14.8% carbohydrate compared to TK 11.6%, 49.8%, 11.4%, 5.2%, 3.1%, and 18.9% for these constituents, respectively. GFK also had 387.0 Kcal/100g energy value compared to 377.4 for TK. Both GFK and TK were highly rated in sensory attributes, however, TK had lesser acceptability. Microbial counts were non detectable in the fresh Kilishi products until week 12 and were within standard safe limits (106 CFU/g aerobic and 107 anaerobic counts) thereafter. At week 12, microbial counts were 2.1x101 CFU/g bacteria and 3.0x100 moulds for GFK stored at ambient (25-32°C) condition and 4.5x101 CFU/g bacteria for GFK stored at refrigerator (7±1°C) conditions, whereas TK had 1.6x101 CFU/g bacteria, 1.0x101 moulds and 1.1x101 CFU/g bacteria. Storage for 12 weeks slightly decreased sensory scores, protein and fat contents and also TBA, FFA, PV but moisture increased slightly. It is possible to produce high quality and yield as well as acceptable and shelf stable Kilishi using conventional defatted groundnut flour. Also GFK Kilishi had better quality attributes when compared with TK, Tunkusa Kilishi.

Body mass index, weight gain during pregnancy and obstetric outcomes
VN Addo
Ghana Medical Journal , 2010,
Abstract: Objectives: To find out the effects of pregnancy weight gain in different body mass index (BMI) groups on maternal and neonatal outcomes in women delivering singletons at term. Design: Retrospective analysis of clinical records of patients attending antenatal clinics and delivering in hospital from January 1st 1992 to December 31st 2009. Setting: A private specialist hospital. Methods: The records of patients starting antenatal care in the first trimester, attending at least four clinics and delivering singletons from 37 completed weeks up to 42 weeks gestation were analysed. Patients’ booking gestational age, height, weight and obstetric and neonatal outcomes at delivery were noted. Results: The total number of deliveries was 2,391 out of which 1755 (72.4%) were analysed. The overweight and obese group compared to the normal were significantly older, shorter, weighed more at booking and gained more weight during pregnancy. The overweight or obese were significantly more likely to have induction of labour and be delivered by caesarean section compared to the normal. Maternal and neonatal outcomes which were more significant in the overweight and obese were macrosomia, stillbirth, perineal trauma, post-partum haemorrhage and retained placenta. Conclusions: Most deliveries in the two BMI groups resulted in normal weight babies. Overweight and Obesity is associated with significantly increased incidence of adverse maternal and neonatal outcomes. It is recommended that further studies involving larger samples comparable to those done in western countries are carried out.
Pregnant women's knowledge of and attitudes to HIV testing at Komfo Anokye Teaching Hospital, Kumasi

Ghana Medical Journal , 2005,
Abstract: A questionnaire survey on the knowledge about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and attitudes to voluntary counselling and testing (VCT) in pregnancy of 334 antenatal attendants at Komfo Anokye Teaching Hospital (KATH) was conducted. The survey showed that HIV/AIDS is recognized as a life-threatening condition and is mainly acquired through unprotected sexual intercourse with an infected partner, use of unsterile sharp instruments and blood transfusion. Knowledge about mother to child transmission (MTCT) was lacking. The majority of women who had done the test did so as a pre-requisite for church blessing of their marriage. VCT would be acceptable especially when anonymity is ensured and drug treatment is available for mother and child should the pregnant woman test positive for HIV.

In vitro propagation and free radical studies of Smilax zeylanicaVent
R Thirugnanasampandan, VN Mutharaian, VN Bai
African Journal of Biotechnology , 2009,
Abstract: A method of micropropagation through multiple shoots formation from nodal segments of Smilax zeylanica Vent. has been developed. The nodal explants were cultured on half strength MS medium containing BA (0.5 mg/l) and IAA (1 mg/l) with activated charcoal (100 mg/100 ml) produced single shoot within 7-10 days. Shoots were multiplied by using nodal segments of in vitro regenerated shoot in modified half strength MS medium supplemented with KIN (2 mg/l), L-Glu (0.5 mg/l) and activated charcoal (100 mg/100 ml). Two shoots were formed. Rooting of the microshoots was achieved in half strength MS medium fortified with IBA (1 mg/l) within three weeks. The rooted plantlets transferred to potting medium containing vermiculite, sand and coir pith (1:1:1). Survival of the plantlets under ex vitro condition was 70%. In vitro antioxidant activities of leaf and stem extracts were performed. Among the extracts tested, ethanol extract of the stem showed maximum DPPH (52.361%) scavenging activity and chloroform extract of stem inhibited hydroxyl radical mediated linoleic acid oxidation up to 50.87%. Ethanol extract of leaf showed maximum reducing power of 0.53. The total free phenolics were found to be 293.3 g in the ethanol extract of leaf.
Determination of sedimentation rates and absorption coefficient of insoluble metal carbonates
VN Mkpenie, FK Onwu
Journal of Applied Sciences and Environmental Management , 2006,
Abstract: Studies on the sedimentation rates of insoluble metal carbonates showed that Zn2+ has a higher sedimentation rate of 5.10x10-2 s-1 while Ni2+ has the lowest sedimentation rates of 1.10 x10-3. The rate of sedimentation of the metal carbonates decreased in the order: Zn2+ > Cd2+ > Cu2+ > Co2+ > Ni2+. The order showed a decrease in the density of the carbonates and also correlated with the decrease in the mass (and particle) absorption coefficient of the metal carbonates.

Measurements of J/$ψ$ yields at forward and mid-rapidity in d+Au, Cu+Cu and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV by PHENIX at RHIC
VN Tram,for the PHENIX collaboration
Physics , 2006,
Abstract: The J/$\psi$ yields in heavy ion collisions are expected to be a promising probe of deconfined matter, since theoretical models predict that the J/$\psi$ production could be strongly suppressed due to color screening effect in a Quark Gluon Plasma. In addition, one of the interesting predictions that has emerged recently is the J/$\psi$ enhancement at RHIC energy via competing mechanisms such as recombination. The PHENIX collaboration has measured J/$\psi$ production via its decay into lepton pairs in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV. The nuclear modification factor $R_{\rm AA}$ for the ${\rm J}/\psi$ is obtained by comparing Au+Au or Cu+Cu collisions to p+p collisions. The $R_{\rm AA}$ dependences on centrality, transverse momentum and rapidity are presented both at forward rapidity ($1.2<|y|<2.2$) using ${\rm J}/\psi\to\mu^+\mu^-$ and at mid rapidity ($|y|<0.35$) using ${\rm J}/\psi\to e^+e^-$. These preliminary results are compared to cold nuclear matter expectations derived from PHENIX d+Au measurements, to results obtained by NA50 experiment and to various theoretical models.
