Carotenoid-Producing sp. nov., Isolated from the West Coast of Dokdo Island, Republic of Korea.

In this study, a novel species within the genus was isolated from the coastal soil of Dokdo (Seodo) Island and investigated. We elucidated the novel species, designated MBLB3053, through genomic analysis of novel functional microbial resources. Cells were gram-negative, non-motile, and coccoid, and the colony was light orange in color.

Metagenome-assembled genomes of the GU0601 sample (the Han River, South Korea).

We generated metagenome sequences of the GU0601 sample collected from the Han River and constructed metagenome-assembled genomes (MAGs) to identify their bacterial composition. We identified six MAGs belonging to Alphaproteobacteria, Cyanobacteria, and Flavobacteria.

Mixotrophic Cultivation of a Native Cyanobacterium, GO0704, to Produce Phycobiliprotein and Biodiesel.

Global warming has accelerated in recent decades due to the continuous consumption of petroleum-based fuels. Cyanobacteria-derived biofuels are a promising carbon-neutral alternative to fossil fuels that may help achieve a cleaner environment. Here, we propose an effective strategy based on the large-scale cultivation of a newly isolated cyanobacterial strain to produce phycobiliprotein and biodiesel, thus demonstrating the potential commercial applicability of the isolated microalgal strain.

Volatile fatty acid-treated mixotrophic cultivation of lipid/carbohydrate-rich cyanobacterial species, Pseudanabaena mucicola GO0704, for the enhancement of biofuel production.

Cyanobacteria-derived biofuels can be helpful in achieving a circular bioeconomy. To increase the production of biodiesel/bioethanol from cyanobacterium, Pseudanabaena mucicola GO0704, mixotrophic cultivation using volatile fatty acid (VFA), a cheap organic carbon source, was performed. The treatment of butyric acid or acetic acid enhanced the cell growth, particularly, the dry weight of the butyric acid-treated cells was 2.

Comparative analysis of oncological outcomes and quality of life after robotic versus conventional open thyroidectomy with modified radical neck dissection in patients with papillary thyroid carcinoma and lateral neck node metastases.

Objectives: Robotic total thyroidectomy (TT) with modified radical neck dissection (MRND) using a gasless transaxillary approach has been reported safe and effective in patients with N1b papillary thyroid carcinoma (PTC), with notable cosmetic benefits when compared with conventional open TT. We have compared oncological outcomes and quality of life (QoL) in PTC patients undergoing robotic TT and MRND and those undergoing conventional open procedures.

Materials And Methods: Between March 2010 and July 2011, 128 patients with PTC and lateral neck node metastases underwent TT with MRND, including 62 who underwent robotic and 66 who underwent open TT.

In vitro and in vivo degradation behavior of acetylated chitosan porous beads.

Chitosans with different degree of acetylation (DA, 10-50%) were synthesized by the acetylation reaction of deacetylated chitosan and acetic anhydride with different ratios. The porous beads (approx. 500 mum) fabricated from the acetylated chitosans were used to investigate the degradation behaviors of chitosans with different DA in vitro and in vivo.

The effect of chitosan bead encapsulating calcium sulfate as an injectable bone substitute on consolidation in the mandibular distraction osteogenesis of a dog model.

Purpose: The purpose of this project was to study the effect of chitosan bead encapsulating calcium sulfate, which provides a sustained release of chitosan and calcium sulfate after implantation, on early bony consolidation in distraction osteogenesis of a dog model.

Materials And Methods: Forty-five dogs were used for this study. An external distraction device was applied to the mandibular body after a vertical osteotomy and mandibular distraction was initiated 5 days after the operation at a rate of 1 mm/day up to a 10-mm distraction.

Effect of PEG-PLLA diblock copolymer on macroporous PLLA scaffolds by thermally induced phase separation.

A regular and highly interconnected macroporous poly(L-lactic acid) (PLLA) scaffold was fabricated from a PLLA-dioxane-water ternary system with added polyethylene glycol (PEG)-PLLA diblock using thermally induced phase separation (TIPS). The morphology of the scaffold was investigated in detail by controlling the following TIPS parameters: quenching temperature, aging time, polymer concentration, molecular structure, and diblock concentration. The phase diagram was assessed visually on the basis of the turbidity.
