Steamed Ginseng Berry Powder Ameliorates Skeletal Muscle Atrophy via Myogenic Effects.

Sarcopenia is an age-related loss of muscle mass and function for which there is no approved pharmacological treatment. We tested direct efficacy by evaluating grip strength improvement in a sarcopenia mouse model rather than drug screening, which inhibits specific molecular mechanisms. Various physiological functions of ginseng berries are beneficial to the human body.

Generation of a CRISPR/Cas9-corrected-hiPSC line (DDLABi001-A) from Fabry disease (FD)-derived iPSCs having α-galactosidase (GLA) gene mutation (c.803_806del).

Fabry disease (FD) is a lysosomal storage disorder caused by mutations in GLA gene. Here, GLA mutation (1268fs*1 (c.803_806del)) of FD iPSCs was corrected using the CRISPR-Cas9 gene editing system.

Enhanced thrombospondin-1 causes dysfunction of vascular endothelial cells derived from Fabry disease-induced pluripotent stem cells.

Background: Fabry disease (FD) is a recessive X-linked lysosomal storage disorder caused by α-galactosidase A (GLA) deficiency. Although the mechanism is unclear, GLA deficiency causes an accumulation of globotriaosylceramide (Gb3), leading to vasculopathy.

Methods: To explore the relationship between the accumulation of Gb3 and vasculopathy, induced pluripotent stem cells generated from four Fabry patients (FD-iPSCs) were differentiated into vascular endothelial cells (VECs).

Fast and Scalable Hydrodynamic Synthesis of MnO/Defect-Free Graphene Nanocomposites with High Rate Capability and Long Cycle Life.

The integration of metal oxides and carbon materials provides a great potential for enhancing the high energy and power densities of supercapacitors, but the rational design and scalable fabrication of such composite materials still remain a challenge. Herein, we report a fast, scalable, and one-pot hydrodynamic synthesis for preparing ion conductive and defect-free graphene from graphite and MnO/graphene nanocomposites. The use of this hydrodynamic method using Taylor-Couette flow allows us to efficiently fast shear-exfoliate graphite into large quantities of high-quality graphene sheets.

Does tranexamic acid increase the risk of thromboembolism after bilateral simultaneous total knee arthroplasties in Asian Population?

Purpose: To ascertain whether tranexamic acid reduces the blood loss and transfusion rate and volumes; increase the prevalence of deep vein thrombosis (DVT); and investigate factors associated with DVT in patients undergoing primary bilateral total knee arthroplasties (TKAs) without use of chemical thromboprophylaxis.

Methods: There were 874 patients (1748 knees) in the control group who did not receive tranexamic acid and 871 patients (1742 knees) in the study group who received tranexamic acid. Mechanical compression device was applied without any chemical thromboprophylaxis.

Interaction between postoperative shivering and hyperalgesia caused by high-dose remifentanil.

Background: High-dose remifentanil-based anesthesia is associated with opioid-induced hyperalgesia (OIH) and postanesthetic shivering (PAS). These effects can be prevented by N-methyl-d-aspartate (NMDA) receptor antagonists. This study aimed to investigate correlations between OIH and PAS caused by high-dose remifentanil and the effects of low-dose ketamine on OIH and PAS.

Methotrexate-incorporated polymeric nanoparticles of methoxy poly(ethylene glycol)-grafted chitosan.

We prepared methotrexate (MTX)-encapsulated polymeric nanoparticles using methoxy poly(ethylene glycol) (MPEG)-grafted chitosan (ChitoPEG) copolymer. MTX-encapsulated polymeric nanoparticles of ChitoPEG copolymer has around 50-300nm in particle size and showed spherical shape when observed by transmission electron microscope (TEM). In (1)H nuclear magnetic resonance (NMR) study, the specific peaks of MTX and chitosan as a drug carrying inner-core disappeared at D(2)O and only the specific peak of MPEG was observed, while specific peaks of MPEG, MTX, and chitosan appeared in DCl/D(2)O mixtures.

Ciprofloxacin-encapsulated poly(DL-lactide-co-glycolide) nanoparticles and its antibacterial activity.

The aim of this study was to prepare ciprofloxacin HCl (CIP)-encapsulated poly(dl-lactide-co-glycolide) (PLGA) copolymer nanoparticles and its antibacterial potential was evaluated with pathogenic bacteria, Escherichia coli (E. coli), in vitro and in vivo. CIP-encapsulated nanoparticles of PLGA were prepared by multiple emulsion solvent evaporation method.

Synthesis and characterization of carboxymethylated cyclosophoraose, and its inclusion complexation behavior.

Carboxymethylated cyclosophoraoses (CM-Cys) were synthesized by chemical modification of a family of neutral cyclosophoraoses isolated from Rhizobium leguminosarum biovar trifolii. Structural analyses of the CM-Cys were carried out using NMR and FTIR spectroscopies, and the molecular weight distributions were confirmed with MALDI-TOF mass spectrometry. Based on structural characterization, native cyclosophoraoses were successfully substituted with carboxymethyl groups at the OH-4 and OH-6 of the glucose residues with degrees of substitution (DS) ranging from 0.

Solubility enhancement of a hydrophobic flavonoid, luteolin by the complexation with cyclosophoraoses isolated from Rhizobium meliloti.

A plant flavone, luteolin is a well-known inducer of nod genes in the Rhizobium meliloti. Its poor aqueous solubility was greatly enhanced by the complexation with a family of cyclosophoraoses synthesized in R.meliloti.
