A microfluidic approach for probing hydrodynamic effects in barite scale formation.

Lab on a chip

Sosa RD, Geng X, Reynolds MA, Rimer JD, Conrad JC.
PMID: 30951060
Lab Chip. 2019 Apr 23;19(9):1534-1544. doi: 10.1039/c9lc00061e.

Crystallization of mineral scale components ubiquitously plagues industrial systems for water treatment, energy production, and manufacturing. Chemical scale inhibitors and/or dissolvers are often employed to control scale formation, but their efficacy in flow conditions remains incompletely understood. We present...

The ECETOC NanoApp was developed to support industry in the registration of sets of nanoforms, as well as regulators in the evaluation of these registration dossiers. The ECETOC NanoApp uses a systematic approach to create and justify sets of...

Onigiri esophagography as a screening test for esophageal motility disorders.

Journal of neurogastroenterology and motility

Hamada S, Ihara E, Muta K, Wada M, Hata Y, Ikeda H, Tanaka Y, Ogino H, Chinen T, Ogawa Y.
PMID: 34312324
J Neurogastroenterol Motil. 2021 Jan 30;28(1):43-52. doi: 10.5056/jnm20138.

BACKGROUND/AIMS: No screening test for esophageal motility disorder (EMD) has been established, the objective of this study is to examine the potential usefulness of our newly developed "Onigiri esophagography" combined with an obstruction level (OL) classification system in screening...

Mechanical strength and gastric residence time of expandable fibrous dosage forms.

International journal of pharmaceutics

Blaesi AH, Kümmerlen D, Richter H, Saka N.
PMID: 34363914
Int J Pharm. 2021 Aug 04;120792. doi: 10.1016/j.ijpharm.2021.120792. Epub 2021 Aug 04.

Expandable, gastroretentive dosage forms are promising for precise control of drug concentration in blood. So far, however, short gastric residence times and safety considerations have limited their use. To mitigate such limitations, in this work expandable fibrous dosage forms...

Hole-Type Spacers for More Stable Shale Gas-Produced Water Treatment by Forward Osmosis.

Membranes

AlQattan J, Kim Y, Kerdi S, Qamar A, Ghaffour N.
PMID: 33401564
Membranes (Basel). 2021 Jan 03;11(1). doi: 10.3390/membranes11010034.

An appropriate spacer design helps in minimizing membrane fouling which remains the major obstacle in forward osmosis (FO) systems. In the present study, the performance of a hole-type spacer (having holes at the filament intersections) was evaluated in a...

Synthesis and Antiscaling Evaluation of Novel Hydroxybisphosphonates for Oilfield Applications.

ACS omega

Mady MF, Rehman A, Kelland MA.
PMID: 33718740
ACS Omega. 2021 Feb 25;6(9):6488-6497. doi: 10.1021/acsomega.1c00379. eCollection 2021 Mar 09.

Organophosphorous compounds are still widely used as potential scale inhibitors in the upstream oil and gas industry, particularly in squeeze treatments as they have good adsorption properties on rock and are easily detectable. However, most phosphonate-based scale inhibitors have...

Esophageal Transit, Contraction and Perception of Transit After Swallows of Two Viscous Boluses.

Gastroenterology research

Dalmazo J, Aprile LR, Dantas RO.
PMID: 27785308
Gastroenterology Res. 2015 Oct;8(5):274-278. doi: 10.14740/gr687w. Epub 2015 Oct 21.

BACKGROUND: There have been results showing the influence of bolus viscosities and consistency on esophageal motility and transit. However, there is no description about the influence of two different viscous boluses on esophageal contractions, bolus transit and perception of...

Barium Appendicitis 6 Weeks After Upper Gastrointestinal Imaging.

Frontiers in pediatrics

Shen G, Sun K, Fan Z.

Barium sulfate is widely used for gastroenterology imaging. Retention of barium in the appendix, where it acts as an appendicolith, thereby leading to obstruction and inflammation. Barium-associated appendicitis is a very rare complication of upper gastrointestinal imaging (UGI), especially...

The Homodigital Propeller Flap: A New Tool for Fingertip Reconstruction. Surgical Technique, Anatomical Study, and Clinical Relevance.

Plastic and reconstructive surgery

Roulet S, Delgove A, Chirez P, Chaput B, Casoli V, Pelissier P, Pinsolle V, Lepivert JC.
