A β-galactosidase from Kluyveromyces lactis was found to specifically catalyze hydrolysis of the glycosyl ester linkage of stevioside to yield steviolbioside, a rare sweetener that also exists in Stevia rebaudiana leaves. In a packed bed reactor, a reaction coupling separation was realized and a production yield of steviolbioside reached 90% in 6 h. The hydrolysis product steviolbioside presented higher cytoxicity on human normal cells (hepatocytes cell L02 and intestinal epithelial cell T84) than stevioside did. Comparing to the typical chemotherapy agent, 5-fluorouracil (5-FU), steviolbioside presents much lower cytotoxicity on all assayed human normal cells; it presented notable inhibition on human hepatocarcinoma cell Hep3B, human breast cancer cell MDA-MB-231 and human pancreatic cancer cell BxPC-3. The remarkable inhibition on MDA-MB-231 cells makes steviolbioside a potential remedy for human breast cancer, when steviolbioside is served as a natural sweetener.

Regarding nutritional benefits, the available studies, while numerous, do not provide proof that the consumption of artificial sweeteners as sugar substitutes is beneficial in terms of weight management, blood glucose regulation in diabetic subjects or the incidence of type 2 diabetes. Regarding nutritional risks (incidence of type 2 diabetes, habituation to sweetness in adults, cancers, etc.), it is not possible based on the available data to establish a link between the occurrence of these risks and the consumption of artificial sweeteners. However, some studies underline the need to improve knowledge of the links between intense sweeteners consumption and certain risks.

The essential oil extracted by hydrodistillation from the flowering twigs of Stevia rebaudiana Bertoni (Asteraceae) was fractioned by chromatography. Forty-three constituents were characterized with the help of GC, GC-MS and other spectroscopic techniques. The essential oil was found to be a complex mixture of mono- and sesqui-terpenes. The cytotoxicity of the essential oil and its fractions was evaluated by sulforhodamine B (SRB) based assay against two cancer cell types viz. C-6 (rat glioma cells) and CHOK1 (Chinese hamster ovary cells). The essential oil and its fractions showed promising cytotoxicity against both cell lines. The highest activity (95.6+/-0.6%) was show by the essential oil on the C-6 cell line at a concentration of 400 microg/mL, which was comparable with that of the standard drug vinblastin.

For the past days I worked on optimizing the Synapse (Matrix) database. Pain in the rear-end. I managed to reduce it from some 300 GB to around 100 GB. Still insane how huge the database is. idk if I can do more...

Now I will try to optimize the Friendica database and start the move to the new servers, little by little. A lot of work ahead.....

in reply to Tio

I had the same issue. It got 60gb on a single user instance and the images were offsite on R2. I stopped hosting one when infosec.exchange went up with their own
in reply to Joseph Hanson

Yeah we are also considering this...to not host our own instance. Seems like a pain...







Faroe Islands - Should you visit or boycott ? Consider this first!


I've spent few weeks in Faroe Islands volunteering and learning about the Grindadrap tradition.
Which is obsolete in modern society and should be banned and forgotten. But it's not happening.
What can we do and if there is a chance to change it?

I am very grateful for organizations which are there on a ground trying to protect pilot whales and Atlantic white sided dolphins. Bunch of brave people acting when politicians and governments keeping quiet.
