BACKGROUND: Free tissue transfer is one option for preservation of form and function in the native limb, in the setting of soft tissue paucity. However, the data on patient functionality after microvascular intervention is inconsistently reported. The Lower Extremity Function Scale (LEFS) measures patient-reported difficulty in carrying out 20 physical activities, on a Likert scale, the sum of which correlates with descriptive functional stages of 1-5. We assess limb functionality in this cohort of microvascular patients using the LEFS survey...

OBJECTIVES: In recent years, the use of del Nido (DN) cardioplegia has been reported in single-valve surgery or isolated coronary artery bypass surgery with acceptable outcomes. The reports of its use in more complex adult cardiac procedures, however, have been scarce. METHODS: We enrolled a total of 149 adult patients who underwent heart valve surgery with the use of DN cardioplegia between May 2014 and December 2016. For a benchmark comparison, 892 patients who underwent cardiac valve surgery with blood cardioplegia during the same period served as controls...

We probed the role of alpha-synuclein (α-syn) in modulating sorting nexin 3 (Snx3)-retromer-mediated recycling of iron transporters in Saccharomyces cerevisiae and Caenorhabditis elegans. In yeast, the membrane-bound heterodimer Fet3/Ftr1 is the high affinity iron importer. Fet3 is a membrane-bound multicopper ferroxidase, whose ferroxidase domain is orthologous to human ceruloplasmin (Cp), that oxidizes external Fe+2 to Fe+3; the Fe+3 ions then channel through the Ftr1 permease into the cell. When the concentration of external iron is low (< 1 µM), Fet3/Ftr1 is maintained on the plasma membrane by retrograde endocytic-recycling; whereas, when the concentration of external iron is high (> 10 µM), Fet3/Ftr1 is endocytosed and shunted to the vacuole for degradation...

BACKGROUND & AIMS: Living-donor liver transplantation (LDLT) can simultaneously cure hepatocellular carcinoma (HCC) and underlying liver cirrhosis, improving long-term results in patients with HCC. ABO-incompatible LDLT could expand the living-donor pool, reduce waiting times for deceased-donor liver transplantation, and improve long-term survival for some patients with HCC. METHODS: We retrospectively reviewed the medical records of patients undergoing LDLT for HCC from November 2008 to December 2015 at a single institution in Korea...

Recent studies have established methods for establishing a rodent model that mimics progressive stages of human Parkinson's disease (PD), via injection of graded doses of 6-hydroxydopamine (6-OHDA) into regions within the nigrostriatal pathway. However, the electrophysiological characteristics of the subthalamic nucleus (STN) in this model have not been fully elucidated in this model. This study aimed to investigate changes in the neuronal activity of the STN in a graded mouse model of PD. Increasing doses of 6-OHDA were unilaterally injected into the medial forebrain bundle (MFB) to produce a hemi-parkinsonian mouse model, mimicking early, moderate, advanced, and severe stages of human PD...

The important platform polysaccharide N-acetylglucosamine (GlcNAc) has great potential to be used in the fields of food, cosmetics, agricultural, pharmaceutical, medicine and biotechnology. This GlcNAc is being produced by traditional methods of environment-unfriendly chemical digestion with strong acids. Therefore, researchers have been paying more attention to enzymatic hydrolysis process for the production of GlcNAc. Hence, in this study, we isolated novel chitinase (Escherichia fergusonii) and chitosanase (Chryseobacterium indologenes, Comamonas koreensis) producing strains from Korean native calves feces, and developed the potential of an eco-friendly microbial progression for GlcNAc production from swollen chitin and chitosan by enzymatic degradation...

Prolonged exposure of the skin to UV radiation causes previtamin D3, the initial photoproduct formed by opening of the B ring of 7-dehydrocholesterol, to undergo a second photochemical reaction where the B-ring is reformed giving lumisterol3 (L3), a stereoisomer of 7-dehydrocholesterol. L3 was believed to be an inactive photoproduct of excessive UV radiation whose formation prevents excessive vitamin D production. Recently, we reported that L3 is present in serum and that CYP11A1 can act on L3 producing monohydroxy- and dihydroxy-metabolites which inhibit skin cell proliferation similarly to 1α,25-dihydroxyvitamin D3...

The 21st Congress for the International Society for Aerosols in Medicine included, for the first time, a session on Pulmonary Delivery of Therapeutic and Diagnostic Gases. The rationale for such a session within ISAM is that the pulmonary delivery of gaseous drugs in many cases targets the same therapeutic areas as aerosol drug delivery, and is in many scientific and technical aspects similar to aerosol drug delivery. This article serves as a report on the recent ISAM congress session providing a synopsis of each of the presentations...

BACKGROUND: Neuroendocrine tumors (NETs) metastasize to the liver. Everolimus and selective internal radioembolization (SIRT) are approved treatments. Pasireotide is a somatostatin analogue with an affinity for somatostatin receptors 1, 2, 3, and 5. Everolimus and pasireotide may potentiate SIRT radiosensitization and inhibit rebound angiogenesis. This study evaluated the safety of pasireotide, everolimus, and SIRT. METHODS: This 3 + 3 phase 1 trial evaluated 3 dose levels of everolimus (2...
