Feeding snails (Archachatina marginata) with leaves: growth performance, carcass characteristics, nutrient digestibility, proximate composition and minerals contents of snail meat.

This study explored the dietary impacts of some plant leaves (Centrosema pubescence leaves, Moringa oleifera leaves and Ipomea batata leaves) on the growth performance and carcass characteristics of Archachatina marginata reared in confinement. A twelve (12) weeks feeding trial on nine hundred and sixty (960) African giant land snails (A. marginata) fed various leaves was evaluated.

Radiometric survey of sediments and health risk assessments from the southern coastal area of Delta State, Nigeria.

Over the years, the release of potential radiological components around the oil exploration environment has increased with potential health implications.Yet; the mechanism and health associated assessment have remained fuzzy to most experimental scientists. The current study determines the activity concentration of radionuclides in sediments and the corresponding health risk assessments from the hydrocarbon exploration environment of the southern coastal area of Delta State, Nigeria.

Polymyxin sensitivity/resistance cosmopolitan status, epidemiology and prevalence among O1/O139 and non-O1/non-O139 : A meta-analysis.

Resistance/sensitivity to polymyxin-B (PB) antibiotic has been employed as one among other epidemiologically relevant biotyping-scheme for into Classical/El Tor biotypes. However, recent studies have revealed some pitfalls bordering on PB-sensitivity/resistance (PBR/S) necessitating study. Current study assesses the PBR/S cosmopolitan prevalence, epidemiology/distribution among O1/O139 and nonO1/nonO139 strains.

Pattern of color inheritance in African catfish (Clarias gariepinus): an expression of a Mendelian law.

In this study the pattern of color of inheritance based on Mendel's laws on the Clarias gariepinus strain was evaluated, to ascertain the different traits of albino, normally pigmented, and a combination of both traits that could be passed across from the parent stocks to the progenies. Since albinism is caused by a series of genetic abnormalities resulting in the reduction of melanin production, partial diallel cross between normally pigmented and albino fish was carried out using two females (albino and normal pigmented brood fish) weighing 2.5 kg and 3 kg, respectively; they were used in crossing two males (albino and normal pigmented brood fish) that weighed 1.

Ingestion exposure of public to natural radionuclides and committed effective dose and cancer risk through tuber crops cultivated in Ebonyi State, Nigeria.

Internal exposure of public to radiation arising from ingestion of natural radionuclides in tuber crops of Ebonyi State origin was investigated in this study. Committed effective doses and lifetime cancer risk of K, Ra, and Th in cassava, cocoyam, water yam, and white yam were calculated. The average activity concentrations of K, Ra, and Th determined by gamma spectrometric Na (TI) detector were, respectively, 199.

Gamma spectroscopy study of soil-plant transfer factor characteristics of K, Th and Ra in some crops cultivated in southwestern region of Nigeria.

Soil-plant transfer factor (TF) is one of the vital variables employed in assessing plants uptake of radionuclides and their transfer to food chain for predictive ingestion dose and risk evaluation. To further this goal, the TF characteristics of natural K, Th and Ra were thus investigated in some crops (yam, cassava, rice, maize, groundnut, cowpea, okra, pumpkin leaf, banana and pawpaw) cultivated in southwestern part of Nigeria using HPGe gamma spectroscopy. The obtained results of activity concentration (AC) of the radionuclides across all the cultivated soil samples indicated average values that are less than the global average, whereas in the crops, average values of Ra and Th, were higher than reference values for different crops group.

Social and economic wellbeing of seafarers across coastal Nigeria amidst Corona virus disease.

One of the industries hit hard by the Corona Virus is the shipping industry. This is because there was serious paucity in the movement of people and goods. This also affected not only the social but also the economic well-being of seafarers.

Prevalence of Listeria monocytogenes in milk in Africa: a generalized logistic mixed-effects and meta-regression modelling.

Listeria outbreaks and food recalls is on the raise globally. Milk particularly is highly susceptible to Listeria as its production and storage adequately support Listeria growth. The extent of milk contamination with Listeria monocytogenes (Lm) and preventative actions to halt milk associated outbreaks in Africa are unknown.
