This paper introduces some new progresses in the researches on the tube baby through the ultra-rapid frozen embryo transfer, the first cloned dog in the world, the tissue reengineering technology, the biotechnology making the plant no-producing pollen, the development of the gene-chip, and the ...
Low temperature freezing can be accomplished in a number of ways, such as by use of a refrigerator or freezer capable of reducing the temperature of the tissue sample below its freezing point, by spraying the tissue sample with gaseous carbon dioxide or other gas capable of freezing the sample...

Another device known as an insulin jet injector works by using a high-pressure blast of air to send a fine spray of insulin through the skin. This may be a good option for those patients that are needle-shy. However, jet injectors require a significant financial investment and aren't ...
an unpleasant taste. From a manufacturing point of view, its is desirable that the tablet formulation yields mechanically robust tablets with low friability and is directly compressible, thus obviating time consuming co-processing such as granulation steps, spray drying and freeze drying. A desirable...
The biodegradable carboxymethyl chitin microspheres (CMCHm) were successfully prepared using an organic solvent-free process in an aqueous two-phase system through simply heating and freeze-drying. To further enhance the hemostatic effect of the microspheres, we loaded calcium ions and in-situ polymeriz...
Selective modification of native proteins in live cells is one of the central challenges in recent chemical biology. As a unique bioorthogonal approach, ligand-directed chemistry recently emerged, but the slow kinetics limits its scope. Here we successfu
This is an important feature of the present invention, as specimens introduced into the rapid freezing apparatus at any point during this time frame will freeze in seconds. Over a period of hours, the dry ice in the reservoir is depleted. However, the temperature in the fluid container is ...
Liposomes, serving as proficient carriers for bioactive compounds like plant extracts, offer a multitude of advantages, encompassing safeguarding fragile substances, extending circulation, and achieving targeted tissue delivery [23]. However, a precise and swift assessment of bioactive compounds’ EE within...
Mass spectrometry was implemented using a DuoSpray ion source in positive and negative ionization modes, respectively. Furthermore, QTOF was configured with an automated calibrant delivery system to perform external calibration for every five samples each time using a calibrated solution. The electrospray...
