Dual lumen extracorporeal membrane oxygenation catheter with single entry port bypassing the right heart and lungs

The invention pertains to a medical device: an ECMO (extracorporeal membrane oxygenation) catheter which can be used during right heart and lung failure. It pertains to a dual lumen catheter with a single port of entry which when in place bypasses the right heart and lungs while completing the veno-arterial circuit.

Extraction, characterization, and antioxidant activity of polysaccharides from ajwa seed and flesh

The date palm has been cultivated in dry and hot areas of the planet for much of human history. In the Kingdom of Saudi Arabia, dates are the main crop used as a source of food. Among several species of date fruits, the Ajwa AL-Madinah date is unique, growing only in Al-Madinah geographical region. The Ajwa date is used in traditional medicine due to its abundant active components and therapeutic properties. This study investigates the structural properties and the antioxidant effects of water-soluble polysaccharides extracted from Ajwa flesh and seed. The polysaccharides were isolated by two techniques including hot water and ultrasonic extraction. After isolation and partial purification, the physicochemical properties of four samples of polysaccharides extracted from flesh and seed were studied by several techniques including FTIR, solid-state NMR, elemental analysis, and mass spectrometry. Several radical scavenging experiments were combined to study the antioxidant activity of the polysaccharide compounds. FTIR and NMR results showed a structure typical of heterogeneous polysaccharides. Mass spectrometry revealed that the polysaccharide samples were composed mainly of mannose, glucose, galactose, xylose, arabinose, galacturonic acid, and fucose. In addition, the physicochemical properties and composition of polysaccharides extracted from flesh and seed were compared. The extracted polysaccharides showed antioxidant activity, with 2, 2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging, Fe chelating ability, hydroxyl free radical scavenging ability, and 2, 2-diphenyl-1-picrylhydrazyl (DPPH …

Microneedle balloon catheter

A microneedle balloon catheter includes a balloon fluidically coupled to a first fluidic channel and microneedles fluidically coupled to a second fluidic channel. The microneedles are on an exterior surface of the balloon. The catheter also includes a guiding sheath. In a first position of the microneedle balloon catheter the balloon, the microneedles, and a portion of the first and second fluidic channels are housed within the guiding sheath. In a second position of the microneedle balloon catheter the balloon and the microneedles are arranged outside of the guiding sheath. The first and second fluidic channels are fluidically isolated from each other.

Using NMR spectroscopy to investigate the role played by copper in prion diseases

Prion diseases are a group of rare neurodegenerative disorders that develop as a result of the conformational conversion of normal prion protein (PrPC) to the disease-associated isoform (PrPSc). The mechanism that actually causes disease remains unclear. However, the mechanism underlying the conformational transformation of prion protein is partially understood—in particular, there is strong evidence that copper ions play a significant functional role in prion proteins and in their conformational conversion. Various models of the interaction of copper ions with prion proteins have been proposed for the Cu (II)-binding, cell-surface glycoprotein known as prion protein (PrP). Changes in the concentration of copper ions in the brain have been associated with prion diseases and there is strong evidence that copper plays a significant functional role in the conformational conversion of PrP. Nevertheless, because …
