With the method, it is possible to prepare a drug-containing polymeric microsphere cost-effectively and conveniently.

Lubricant compositions comprising certain mixtures of esters of pentaerythritol, di-pentaerythritol, tri-pentaerythritol and higher pentaerythritol oligomers are ideally suited for use with CO₂ as refrigerant in heat transfer devices provided that at least 30% by weight of the esters are esters of pentaerythritol oligomers containing 4 or more pentaerythritol monomer units and wherein a majority of the alkylcarboxylate groups are straight chain C_3-6 alkanoyl groups, such as n-pentanoyl. Said mixture of alkylcarboxylate esters are shown to not only have higher than expected viscosity and exceptional CO₂ miscibility, but also possess excellent lubricity, film building properties and load bearing properties even as part of a lubricant/CO₂ solution.

The invention relates to a method for removing phorbol esters from Jatropha curcas seed oil by extraction. The method comprises drying Jatropha curcas seed oil meal obtained from pre-squeezing and leaching processes, grinding into powder, mixing with industrial methanol at a weight ratio of 3.5:1.1 at 30 DEG C for more than 20 min, filtering to separate oil meal and methanol phase, collecting the oil meal and heating to remove residual methanol in the oil meal to obtain detoxicated plant protein; and concentrating the separated methanol phase to obtain phorbol ester product. After removing phorbol esters by methanol extraction, the content of phorbol esters in the oil meal is reduced from 1.78% to 0.014%, so that the oil meal can be used in preparing feed proteins.

The present invention relates to the device for animal inspection and quarantine and the preparation method thereof. The present invention is especially applicable to the detection of the pathogen of bovine spongiform encephalopathy (BSE) (also known as “mad cow disease”). The present invention employs a piezoelectric chip, a microelectrode array and a common electrode fixed on the lower side surface and upper side surface of the piezoelectric chip, respectively, and a BSE PrP antibody array to constitute the piezoelectric biochip for the detection of the BSE pathogen. The BSE PrP antibodies are immobilized on the electrodes of the microelectrode array in a format corresponding uniquely to the electrodes of the microelectrode array by adsorbing, bonding, cross-linking, embedding or self-assembly process. The combination of the piezoelectric biochip and a detector constitutes the piezoelectric biochip detection system for the BSE pathogen. When the antibodies react with the corresponding PrPs immunochemically, the information about the PrPs can be detected at real time by measuring the resonant frequency, and the PrPs thus can be analyzed qualitatively and quantitatively. The present invention is applicable to the early, effective and rapid detection of the BSE pathogen.
