Preparation and separation of food grade cellooligosaccharides

, 2004
Bu araştırmada sellooligosakkaritlerin selüloz sabit fazı ile ayrıştırılması çalışılmıştır. Bu çalışmanın motivasyonu ise gıdalarda sellooligosakkaritlerin fonksiyonel sindirilmeyen oligosakkaritler olarak kullanımıdır. Burda selüloz sabit fazı kullanarak sellooligosakkaritlerin etanol-su hareketli fazı ile ayrıştırılmasına bakılmıştır.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Protein separation using preparative‐scale dynamic field gradient focusing

, 2008
Dynamic field gradient focusing uses an electric field gradient to separate and concentrate proteins in native buffers. A prototype preparative‐scale dynamic field gradient focusing apparatus reproducibly separated hemoglobin and bovine serum albumin ...

Development of a Process for Separation of Mogroside V from Siraitia grosvenorii by Macroporous Resins

Molecules, 2011
A separation method was developed for the preparative separation and enrichment of the non-caloric sweetener mogroside V from Siraitia grosvenorii. The adsorption properties of six macroporous resins were evaluated.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Cromatografia de troca-iônica aplicada ao isolamento da fração ácida do óleo de copaíba (Copaifera multijuga) e da sacaca (Croton cajucara) Ion exchange chromatography applied to the fractionation of the copaíba oil (Copaifera multijuga) and sacaca (Croton cajucara) extracts

Química Nova, 2005
Plant extracts are usually complex mixtures which contain several molecules of different sizes with varied functional groups. Such extracts are a challenge to the chemist of natural products.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.
