Rapid identification of glycosylation sites of glycoproteins is urgently needed in glycoproteomics study. In the present work, a rapid and simple method based on non-specific digestion of gel-separated glycoproteins and matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry was described, which can efficiently identify the N-linked glycosylation sites. One-step in-g...

We synthesized the uniform core-shell microstructured compounds with hexagonal phase NaYF₄:Er/Yb microrods as the core and hexagonal phase NaLnF₄ (NaYbF₄, NaLuF₄:Yb/Tm, NaYF₄:Yb/Er, NaYF₄:Eu) as the shell based on the hydrothermal reaction. These microscale core-shell structures provided a platform for the spatially confining optical process while possessing high luminescence efficiency. The th...

Sewage sludge biochars were obtained at different pyrolysis temperatures from 300°C to 900°C and their macro- and microscale properties were analyzed. The biochar's plant-available nutrients and humus-like substances in the water-extractable phase and fixed nutrients in the solid fraction were evaluated for their potential agronomic implications. FT-IR, Raman, XRD, XPS, and SEM techniques were ...

Objective: To research distribution of etiologies modification of arthritis in Congo-Brazzaville, twenty years after the first reports. Methods: A cross sectional study has been achieved. Medical files of patients admitted for arthritis between 2000 and 2014, in Rheumatology department of Brazzaville university teaching hospital have been included. Among 416 patients listed as cases of arthriti...

MOTIVATION Experimental evidence suggests that certain short protein segments have stronger amyloidogenic propensities than others. Identification of the fibril-forming segments of proteins is crucial for understanding diseases associated with protein misfolding and for finding favorable targets for therapeutic strategies. RESULT In this study, we used the microcrystal structure of the NNQQNY...

This paper describ_es applications in microfabrication using patterned sel f -assembled monolayers (SAMs) formed by microcontact pr int ing."Microcontact pr int ing (7rCP) is a f lexible new technique that forms patterned SnMs with regions terminated by di f ferent chemical funct ional i t ies (and thus di f ferent physicat and chemical propert ies), in patterns wi th pm dimensions. Patterns of...

The colloidal nature of perovskite precursor solution highly determines the quality film and photovoltaic performance a solar cell (PSC). Herein, we demonstrate facile method to fabricate high-quality all-inorganic CsPbIBr2 by regulating temperature solution. After characterization, stable microcrystals with size up 1 have been formed under high temperatures, more suitable for preferable crysta...
