On-chip pumps achieve high-speed sorting of large cells
Nagoya University research developed a high-speed cell sorting method of large cells with high-viability using dual on-chip pumps. The microfluidic chip has three-branched microchannels. Target cells are sorted into one of two interest channels by the high-speed flow produced by the on-chip pumps, while non-target cells enter a waste channel without pump actuation. The technique overcomes the limitation of many on-chip cell sorting methods in achieving the sorting of large cells at a high throughput. (2017-07-28)

Identification of flavonoids from plant parts and callus culture of Gymnema sylvestre R.Br.
Gymnema sylvestre R. Br. is an important medicinal plant (Family: Asclepiadaceae). It has been used as an antidiabetic agent in traditional medicines. The hypoglycemic activity has also been validated through clinical trials and studies on animal models. Extensive use of G. sylvestre for phytoceuticals has led to its depletion from the natural habitat and thus, the plant finds its presence in the list of endangered plant species of India.

TERRA, the RNAs that protect telomeres
Despite their especially compact structure that is difficult to access, telomeres transcribe information like the rest of the DNA. The RNAs resulting from this process are called TERRA and their function is essential in preserving these protective structures. This is the conclusion of a new study by the Telomere and Telomerase Group at the Spanish National Cancer Research Centre, which has also located the part of the human genome where these molecules are 'manufactured.' (2016-08-17)

Brazilian study identifies new target for treatment of melanoma
A Brazilian study shows that inhibition of an RNA named RMEL3, which is encoded by a previously uncharacterized gene (also named RMEL3), can reduce the viability of cultured melanoma cells by up to 95%. Although RMEL3 is a non-coding RNA and hence does not contain information for protein synthesis, it appears to modulate the main signaling pathways related to cell proliferation and survival. (2016-08-03)

Study suggests physical cause for cell death in dry preservation
Brine shrimp do it, water bears do it, why can't we dry preserve snow leopard or golden toad embryos and keep them on the shelf? A new study has determined that a critical issue in dry preserving whole cells may lie in the late-stage dynamics of sugar molecules as they transition into a glass state. The finding suggests possible solutions. (2016-07-14)

Mitochondrial DNA levels as a marker of embryo viability in IVF
Despite the claims and counter-claims for new embryo assessment techniques introduced over the past two decades, the search for the holy grail of assisted reproduction -- the key to the embryo destined to implant -- continues. Genetic screening techniques so far have relied largely on the assessment of one component of the embryo's genetic constitution, the number of chromosomes in its cells. (2016-07-04)
