Assessment of healthcare waste generated by some selected public hospitals in Katsina State, Nigeria

This article has been retracted by the journal Editor.Healthcare wastes include anatomical, pathological and clinical infectious/ hazardous organic and inorganic waste. The waste is disposed off in unscientific manner. The study has been conducted in the government hospitals only to reveal the per day waste generation on each patient, present mode of waste management within the units bed, our suggestions which will help the units to improve their waste management practices, in Katsina State, Nigeria.Keywords: Waste management, Health care waste, Management Katsina Stat

Quantal description of nucleon exchange in stochastic mean-field approach

Nucleon exchange mechanism is investigated in central collisions of symmetric heavy-ions in the basis of the stochastic mean-field approach. Quantal diffusion coefficients for nucleon exchange are calculated by including non-Markovian effects and shell structure. Variances of fragment mass distributions are calculated in central collisions of ${}^{40}$Ca + ${}^{40}$Ca, ${}^{48}$Ca + ${}^{48}$Ca and ${}^{56}$Ni + ${}^{56}$Ni systems

Hyperglycemic effect and hypertotoxicity studies of stem bark of Khaya senegalensis and leaf extract of Camellia sinesis

Hepatotoxic properties of the aqueous leaves of highland tea (Camellia sinesis) and aqueous stem bark extract of Khaya senegalensis were studied in rats. This was done by assaying the serum activities of aspartate aminotransferase(AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), glucose and bilirubin in rats administered with 6.5mg/Kg (group A), 4.35mg/Kg (group B) and 3.0mg/Kg (group C) of the extract for seven (7) days respectively. The serum AST, ALT, ALP, glucose, bilirubin (total) and bilirubin (direct) in the control rats (group D) were found to be 7.62 + 1.78U/L, 11.2 + 0.38U/L , 144.9 + 23.90U/L , 4.39 + 0.08mmol/l, 0.14 + 0.03mg/dl and 0.18 + 0.04mg/dl respectively. The serum AST, ALT, glucose, bilirubin (total) and bilirubin (direct) in group A rats showed significant increase (

Static and Dynamic Chain Structures in the Mean-Field Theory

We give a brief overview of recent work examining the presence of $\alpha$-clusters in light nuclei within the Skyrme-force Hartree-Fock model. Of special significance are investigations into $\alpha$-chain structures in carbon isotopes and $^{16}$O. Their stability and possible role in fusion reactions are examined in static and time-dependent Hartree-Fock calculations. We find a new type of shape transition in collisions and a centrifugal stabilization of the $4\alpha$ chain state in a limited range of angular momenta. No stabilization is found for the $3\alpha$ chain.Comment: Fusionn 11 Conference, St. Malo, France, 201

Anti-microbial activities and phytochemical screening of some commonly used chewing sticks in Kano, Nigeria

This research work was aimed to determine the antibacterial activity of aqueous and ethanolic extract of plants commonly used in Kano on a clinical isolate of Staphylococcus and Streptococcus species obtained from the dental problem with a view to find the most efficacious one among them. The sensitivity disc method was used to test the antibacterial activity of chewing sticks, Eucalyptus globulus, Salvadora persica, Gledistsia triacanthos, Azadirachta indica and Jatropha curcas were the plants. It was found that none of the plants ‘aqueous extract had activity on the two species of the bacterial isolate at various concentrations. But ethanolic extract was active against all the test bacterial isolate obtained from the dental problem with a greater zone of inhibition in A. Indica, followed by E. globulus and a smaller zone of inhibition in J. curcas. Some of the secondary metabolites were all present with high content in ethanolic extract. The extracts of these plants may serve as sources for chemotherapeutic agents of the management of orofacial infection

Control of filariasis vector using Ovillanta in Gwale local Government area of Kano State, Nigeria

The study was aimed at finding the effectiveness of a physical method of controlling filariasis vector larvae. Four ovillanta traps were placed in four different sites (north, south, west and east) of Gwale Local Government area of Kano state. The eggs and immature stage(larvae) of the filariasis vector were collected and destroyed. A total of 134667 larvae were collected altogether. 25% from site A, 23% from site B, 28% from site C and 24% from site D.The finding of the study shows that ovillanta trap is an effective method in controlling filariasis vector. &nbsp

Larvicidal activity of some selected medicinal plant extracts against the vector of filariasis

The present study assessed the role of larvicidal activities of hexane, ethyl acetate and methanol dried leaf and bark extracts of Ocimum gratissimum, Gleditsia triacanthos, Eucalyptus sglobulus and Azadirachta aindica against the fourth instar larvae of filariasis vector, Culex quinquefasciatus mosquito (Diptera: Culicidae). Larvicidal activities of four medicinal plant extracts were studied in the range of 4.69 to 1000 mg/l in the laboratory bioassays against early 4th instar larvae of Culex quinquefasciatus. The mortality data were subjected to probit analysis to determine the lethal concentrations (LC50 and LC90) to kill 50 and 90 per cent of the treated larvae of the respective species. All plant extracts showed moderate effects after 24 h of exposure; however, the highest toxic effect of leaf methanol extract of Ocimum gratissimum, bark ethyl acetate extract of Eucalyptus globulus, methanol extract of Azadirachta indicia and methanol bark extract of Gleditsia triacanthos against the larvae of Culex quinquefasciatus with LC50=43.00, 41.02, 40.12 and 20.36 mg/l; LC90=278.32, 218.72, 215.01 and 86.29 mg/l respectively. The result of findings shows that leaf and bark extract of G. tricantha, A .indica, O. gratissimum and E .globulus can be developed as ecofriendly larvicides
