Biolubricant was synthesized from Cameroon palm kernel oil (PKO) by double transesterification, producing methyl esters in the first stage which were then transesterified with trimethylolpropane (TMP) to give the PKO biolubricant in the presence of a base catalyst obtained from plantain peelings (municipal waste). The yields from both catalysts were significantly similar (48% for the locally produced and 51% for the conventional) showing that the locally produced catalyst could be valorized. The synthesized biolubricant was characterized by measuring its physical and chemical properties. The specific gravity of 1.2, ASTM color of 1.5, cloud point of 0°C, pour point of -9°C, viscosities at 40°C of 509.80 cSt and at 100°C of 30.80 cSt, viscosity index of 120, flash point greater than 210°C and a fire point greater than 220°C were obtained. This synthesized biolubricant was found to be comparable to commercial T-46 petroleum lubricant sample produced industrially from mineral sources. We have therefore used local materials to produce a biolubricant using a cheap base catalyst produced from municipal waste.

Aim: To determine the seminal concentrations of copper, zinc, iron, cadmium, lead and nickel in bulls, rams, boars, stallions and foxes and study their correlations. Methods: Semen samples were obtained, digested and analyzed by means of the atomic absorption spectrophotometer. Data were analyzed statistically with the Student's t-test and Scheffe's test using PC programs SAS and Excel. Results: The seminal copper concentration was significantly higher in ram [(2.49±0.18) mg/kg] and fox [(2.16±0.53) mg/kg] than that in bull [(1.64±0.21) mg/kg], boar [(1.64±0.28) mg/kg] and stallion (0.86 mg/kg). In boar a significantly higher seminal zinc concentration (171.74±65.72) mg/kg] was found in comparison with stallion [(86.20±45.88) mg/kg], bull [(83.15±61.61) mg/kg], ram [( 60.46±35.37) mg/kg] and fox (13.09±5.22) mg/kg]. The iron concentration in semen was significantly higher in ram [(40.32±10.81) mg/kg), bull [(38.04±22.07) mg/kg] and fox [(33.16±24.36) mg/kg] than that in boar [(16.14±10.35) mg/kg] and stallion (12.68 mg/kg). The seminal cadmium concentration was relatively low [(0.05-0.12) mg/kg] in all studied species. The seminal lead concentration was the highest in ram [(0.35±0.68) mg/kg], which was much higher than in fox [(0.08±0.06) mg/kg], bull [(0.06±0.04) mg/kg], stallion [(0.05±0.05) mg/kg] and boar [0.02±0.03) mg/kg]. The level of seminal nickel was significantly higher in fox [(0.35±0.24) mg/kg] and ram [(0.31±0.19) mg/ kg] in comparison with bull [(0.12±0.07) mg/kg] and boar [(0.06±0.08) mg/kg]. The concentration of nickel in the semen of stallion was (0.20±0.24) mg/kg. There was a high positive correlation between seminal iron and zinc in bull (r=0.723) and stallion (r=0.723), between cadmium and lead in ram (r=0.976) and boar (r=0.973) and between iron and cadmium (r=0.783) and iron and lead (r=0.791) in boar. A high negative correlation between seminal nickel and copper in ram (r=-0.709) and between seminal copper and lead in fox (r=-0.854) was found

Since the first description of multiple sclerosis （MS）, it has been known that relapse of the disease may be triggered by febrile infections. Although the prevention of febrile illness is therefore clearly advantageous for those with MS there is considerable controversy as to whether vaccine should be administered to such individuals. A further subject of debate is the possibility that vaccination （against influenza,

Of the 206 patients who contracted Severe Acute Respiratory Syndrome (SARS) in Singapore five developed large artery cerebral infarctions. Four patients were critically- ill and three died. Intravenous immunoglobulin was given to three patients. An increased incidence of deep venous thrombosis and pulmonary embolism was also observed among the critically- ill patients. We believe our experience warrants an increased vigilance against stroke and other thrombotic complications among critically- ill SARS patients in future outbreaks, especially if treatment such as intravenous immunoglobulin, that increases pro- thrombotic tendency, is contemplated.
