Algal polysaccharides for 3D printing: A review.

Algae hold particular promise as a feedstock for biomaterials, as they are capable of producing a wide variety of polymers with the properties required for 3D printing. However, the use of algal polymers has been limited to alginate, agar, carrageenan, and ulvan extracted from seaweeds. Diverse algal taxa beyond seaweeds have yet to be explored.

Midterm safety and outcome of balloon angioplasty of native aortic coarctation in neonates and young infants and initial experience of prepartial dilatation using high-pressure noncompliant balloon.

Background: Balloon angioplasty (BA) for aortic coarctation in neonates and infants remains controversial due to high recurrence rate and vascular complications.

Aim: This study aimed to determine the safety and outcome of percutaneous treatment of coarctation in neonates and infants and to share the initial experience of strategy of prepartial dilatation with high-pressure noncomplaint balloon before final targeted dilatation using low-pressure compliant balloon.

Materials And Methods: Retrospective analysis of records of all neonates and infants aged <6 months who underwent BA either using only low-pressure balloon (Group A) or those with prepartial dilatation using high-pressure noncomplaint balloon followed by low-pressure compliant balloon (Group B) between July 2017 and February 2020 was performed.

A systematic review and meta-analysis of randomised controlled trials in the management of neovascular glaucoma: absence of consensus and variability in practice.

Purpose: Neovascular glaucoma (NVG) is characterised by neovascularisation of the angle and therefore elevated intraocular pressure (IOP). This results in progressive optic neuropathy and loss of visual acuity. Treatment aims to reduce IOP in order to prevent optic nerve damage.

Microbial CO fixation and biotechnology in reducing industrial CO emissions.

The rapid acceleration in emissions of inevitably generated CO due to numerous activities mainly anthropogenic have devastating environmental effects leading to climatic concerns. Hence, significant, sustainable approaches should be developed for reduction of CO emission targets, balancing the existing needs of the current population. Biological carbon acquisition, storage and usage are considered crucial alternative strategies in assimilating inorganic carbon, manifested by diverse variety of microorganisms.
