Synthesis of C-Oligosaccharides through Versatile C(sp3 )-H Glycosylation of Glycosides. [PDF]

open access: yesAngew Chem Int Ed Engl, 2022
The palladium‐catalyzed C(sp3)−H glycosylation of glycosides is disclosed. This saccharide assembly by C(sp3)−H glycosylation featured excellent site‐ and stereoselectivity and enabled the efficient synthesis of diverse C‐disaccharides and C‐trisaccharides.

Ionic selectivity and regulation of maitotoxin-activated nonselective cation channels in rat cardiac myocytes [PDF]

open access: green, 2003
Maitotoxin (MTX) reversibly activated a nonselective cation channel in ventricular rat myocytes, which had an ion selectivity sequence of K + > Rb+ > Cs+ > Na+ = Li+ > NMDG.

The Formosalides: Structure Determination by Total Synthesis

open access: yesAngewandte Chemie, Volume 133, Issue 1, Page 450-458, January 4, 2021., 2021
Total synthesis allowed the identification of the most likely stereostructure of the cytotoxic marine macrolides of the formosalide family (see structure) from eight possibilities. The successful route was based upon an inherently flexible blueprint that builds all stereogenic centers by strictly catalyst controlled transformations prior to formation ...

Two‐pore channel 1 and Ca2+ release‐activated Ca2+ channels contribute to the acrosomal pH‐dependent intracellular Ca2+ increase in mouse sperm

open access: yesThe Journal of Physiology, Volume 601, Issue 14, Page 2935-2958, 15 July 2023., 2023
Abstract figure legend Amphipathic weak bases like CatSper blockers (B) diffuse across the sperm plasma membrane from a region of high concentration to one of low concentration (1). Inside the cell, these compounds are accumulated and protonated (BH+) into the acrosomal lumen (2).

Health benefits of microalgae and their microbiomes

open access: yesMicrobial Biotechnology, Volume 15, Issue 7, Page 1966-1983, July 2022., 2022
Microalgae may offer solutions to the societal challenge we face concerning the lack of antibiotics treating the growing level of antimicrobial resistant bacteria and fungi in clinical and industrial settings. While the vast majority of microalgae and their associated microbiota are unstudied, they may be a fascinating and rewarding source for novel ...

Synthese von C‐Oligosacchariden via vielseitiger C(sp3)‐H‐Glykosylierung von Glykosiden

open access: yesAngewandte Chemie, Volume 134, Issue 11, March 7, 2022., 2022
Die Palladium‐katalysierte C(sp3)‐H‐Glykosylierung von Glykosiden wird erschlossen. Diese Saccharid‐Assemblierungsstrategie durch die C(sp3)‐H‐Glykosylierung zeichnet sich durch eine ausgezeichnete Site‐ und Stereoselektivität aus und ermöglicht die effiziente Synthese verschiedener C‐Disacchariden und C‐Trisacchariden.

Critical Review and Conceptual and Quantitative Models for the Transfer and Depuration of Ciguatoxins in Fishes

open access: yesToxins, 2021
We review and develop conceptual models for the bio-transfer of ciguatoxins in food chains for Platypus Bay and the Great Barrier Reef on the east coast of Australia.

New insights into maitotoxin action [PDF]

open access: yesEuropean Journal of Biochemistry, 1988
Maitotoxin (3 ng/mol) induced a massive uptake of 45Ca2+ into BC3H1 cells. This effect exhibits a lag phase of 3 min. Inositol diphosphate formation occurred concomittantly with the 45Ca2+ uptake but inositol monophosphate formation was found only after a 5‐min delay following toxin addition.

Plesiomonas: A Review on Food Safety, Fish‐Borne Diseases, and Tilapia

open access: yesThe Scientific World Journal, Volume 2021, Issue 1, 2021., 2021
Fish and fish products are considered a fundamental part of the human diet due to their high nutritional value. Food‐borne diseases are considered a major public health challenge worldwide due to their incidence, associated mortality, and negative economic repercussions. Food safety is the guarantee that foods will not cause harm to the health of those
