The Synthesize of Calcium Carbonate Its Characterization and Experimental Design in an Ultrasonic Sound Wave Environment and in the Presence of Polyelectrolyte

Gazi Üniversitesi Fen Bilimleri Dergisi, 2017
In this study, calcium carbonate (CaCO3) was synthesized by means of ultrasonic irradiation process in the presence of the water-soluble polyelectrolyte Poly(Vinyl Sulfonic Acid) (PVS).

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Adsorption of Methyl Violet 2B Dye by Silica from Glass Bottle Waste

Indonesian Journal of Chemistry
In this study, silica gel was successfully synthesized using waste from chemical reagent glass bottles. The synthesized silica gel was then tested for its effectiveness in adsorbing methyl violet 2B dye.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Synthesis and Design of 3-D Microwave Absorber With 70° Angular Stability for C-Band and X-Band

IEEE Open Journal of Antennas and Propagation
This article presents the synthesis and design of 3-D microwave absorber with 70° angular stability for C-band and X-band. The operating principle is firstly investigated, where the absorber is considered as an energy convertor.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Low-cost synthesis of high-quality graphene in do-it-yourself CVD reactor

Automatika, 2018
This paper reports design of a very low-cost (less than 2000 USD) chemical vapour deposition (CVD) reactor for graphene synthesis, based on readily available off-the-shelf components.

Design and Syntheses of a Series of Novel Serotonin3 Antagonists.

Chemical and Pharmaceutical Bulletin, 1993
From a structural comparison study between serotonin and serotonin3 (5-HT3) antagonists using a two-dimensional grid template composed of regular hexagons, we deduced structural modification patterns from agonists to antagonists, and designed new 5-HT3 antagonist prototypes. Among them, 2-(4-methyl-1-piperazinyl)-1-butylbenzimidazole (6) was identified

Discerning protein pools by selective staining with self‐labeling tags

FEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
