We compared the transcriptome, proteome, and nucleotide sequences between the parent strain Escherichia coli W3110 and the L-threonine-overproducing mutant E. coli TF5015. DNA macroarrays were used to measure mRNA levels for all of the genes of E. coli, and two-dimensional gel electrophoresis was used to compare protein levels. It was observed that only 54 of 4,290 genes (1.3%) exhibited differential expression profiles. Typically, genes such as aceA, aceB, icdA, gltA, glnA, leu operon, proA, th

Several regulatory proteins control cell cycle progression. These include Emi1, an anaphase-promoting complex (APC) inhibitor whose destruction controls progression through mitosis to G1, and p21(WAF1), a cyclin-dependent kinase (CDK) inhibitor activated by DNA damage. We have analyzed the role of p21(WAF1) in G2-M phase checkpoint control and in prevention of polyploidy after DNA damage. After DNA damage, p21(+/+) cells stably arrest in G2, whereas p21(-/-) cells ultimately progress into mitosi

STUDY DESIGN: .: Prospective observational 1-year study. OBJECTIVE: .: To determine minimum clinically important difference (MCID) and substantial clinical benefit (SCB) of outcome measures in failed back surgery syndrome (FBSS) patients, as these metrics enable assessment of whether and when an intervention produces clinically meaningful effects in a patient. SUMMARY OF BACKGROUND DATA: .: Several methods have been devised to quantify clinically important difference, but MCID and SCB for FBSS p

BACKGROUND: Lumbar disc herniation is a major cause of sciatica and low back pain and imposes a heavy burden on both individual and society. While use of pharmacopuncture, a combined form of acupuncture and herbal medicine, for lumbar disc herniation is widespread in Korea and China, there is a paucity of research. METHODS/DESIGN: This study is the protocol for a three-armed, randomized, patient, physician, and assessor-blinded controlled pilot study. Sixty patients with severe non-acute sciatic

Despite limitations as an observational study, integrative Korean medicine treatment showed positive results in pain, function, and quality of life of FBSS patients.

The long‐term course to lumbar intervertebral disc herniation (LDH) patients receiving integrative Korean medicine treatment and predictive factors associated with disc resorption were investigated. LDH patients who received integrative Korean medicine treatment from February 2012 to December 2015 and were registered in the “longitudinal project for LDH on MRI” were included. Disc resorption amount was measured 3‐dimensionally with disc degeneration and modic change levels on baseline and follow

The aim of this study was to examine the effects of human umbilical cord blood-derived CD34-positive endothelial progenitor cells (CD34+ EPCs) on osteoblastic differentiation of cultured human periosteal-derived osteoblasts (POs). CD34+ cells from human umbilical cord blood were sorted to purify more EPCs in characterization. These sorted cells showed CD31, VE-cadherin, and KDR expression as well as CD34 expression and formed typical tubes in Matrigel. These sorted cells were referred to as huma

OBJECTIVE: This retrospective database analysis was conducted to evaluate the use and cost of new-generation antihistamines (i.e., those that are nonsedating) in the treatment of allergic rhinitis in a managed care population. STUDY DESIGN: The study is a retrospective database review of medical and pharmacy-related claims linked by episodes of care. METHODS: Patients who had been diagnosed as having allergic rhinitis and had at least 1 prescription claim were identified from a database containi

Matsumura bark methanol extract (PYE) on scald-induced dorsal skin wounds in rats. Scalds were produced in Sprague-Dawley rats with 100°C water and treated with 5% and 20% PYE (using Vaseline as a base), silver sulfadiazine (SSD), and Vaseline once a day for 21 days, beginning 24 hours after scald by treatment group allocation. The PYE-treated groups showed accelerated healing from 12 days after scald, demonstrated by rapid eschar exfoliation compared to the control and SSD groups. PYE-treated g
