Kurşun Asit Aküler İçin Kalıcı Sülfatlaşmayı Ortadan Kaldıran Yenilikçi Bir Akü Koruma Cihazı Tasarımı

open access: yesSakarya University Journal of Computer and Information Sciences, 2019
Akülerde çalışma kalitesini belirleyen en temel ölçüt kutuplar arasındaki gerilim seviyesinin kararlılığı olup bu kararlılığı bozan temel sebep akü elektrolizinde meydana gelen "sülfatlaşma" olayıdır.

New tools for evaluating protein tyrosine sulfation and carbohydrate sulfation [PDF]

open access: yes, 2018
Sulfation is a common modification of extracelluar glycans and tyrosine residues on proteins, which is important in many signalling pathways and interactions.

The 3'-phosphoadenosine 5'-phosphosulfate transporters, PAPST1 and 2, contribute to the maintenance and differentiation of mouse embryonic stem cells.

open access: yesPLoS ONE, 2009
Recently, we have identified two 3'-phosphoadenosine 5'-phosphosulfate (PAPS) transporters (PAPST1 and PAPST2), which contribute to PAPS transport into the Golgi, in both human and Drosophila.

Chemical Modification of Glycosaminoglycan Polysaccharides

open access: yesMolecules, 2021
The linear anionic class of polysaccharides, glycosaminoglycans (GAGs), are critical throughout the animal kingdom for developmental processes and the maintenance of healthy tissues.

Induction of defense in apples by sulfated and deacetylated chichá gum

open access: yesPolímeros, 2021
Elicitors activate the defense mechanism in plants to resist pathogens. Ulvans and glucuronans can act as elicitors, and their activity seems to be related to the sulfate groups, rhamnose and uronic acid monosaccharides.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Study for the Access to a Semi-synthetic Regioisomer of Natural Fucosylated Chondroitin Sulfate with Fucosyl Branches on N-acetyl-Galactosamine Units

open access: yesMarine Drugs, 2019
Fucosylated chondroitin sulfate (fCS) is a glycosaminoglycan found up to now exclusively in the body wall of sea cucumbers. It shows several interesting activities, with the anticoagulant and antithrombotic as the most attractive ones.

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Direct Sulfation of Limestone

open access: yes, 2007
The direct sulfation of limestone was studied in a laboratory fixed-bed reactor. It is found that the direct sulfation of limestone involves nucleation and crystal grain growth of the solid product (anhydrite).

Sulfation of Condensed Potassium Chloride by SO2 [PDF]

open access: yes, 2013
The interaction between alkali chloride and sulfur oxides has important implications for deposition and corrosion in combustion of biomass. In the present study, the sulfation of particulate KCl (90–125 μm) by SO2 was studied in a fixed bed reactor in ...
