Comparison of Fracture Strength of Milled and 3D-Printed Crown Materials According to Occlusal Thickness.

This study aimed to measure the fracture strengths and hardness of final restorative milled and 3D-printed materials and evaluate the appropriate crown thickness for their clinical use for permanent prosthesis. One type of milled material (group M) and two types of 3D-printed materials (groups P1 and P2) were used. Their crown thickness was set to 0.

The S100 calcium-binding protein A4 level is elevated in the lungs of patients with idiopathic pulmonary fibrosis.

Background: Fibroblast dysfunction is the main pathogenic mechanism of idiopathic pulmonary fibrosis (IPF). S100 calcium-binding protein A4 (S100A4) plays critical roles in the proliferation of fibroblasts and in the development of pulmonary, hepatic, and renal fibrosis. However, the clinical implications of S100A4 in IPF have not been evaluated.

Two Indias: The structure of primary health care markets in rural Indian villages with implications for policy.

We visited 1519 villages across 19 Indian states in 2009 to (a) count all health care providers and (b) elicit their quality as measured through tests of medical knowledge. We document three main findings. First, 75% of villages have at least one health care provider and 64% of care is sought in villages with 3 or more providers.

Global DNA Methylation Pattern of Fibroblasts in Idiopathic Pulmonary Fibrosis.

Our previous transcriptome study of cultured fibroblasts identified 178 genes that were differentially expressed by 8 idiopathic pulmonary fibrosis (IPF) fibroblasts compared with 4 controls. Here, we performed genome-wide DNA methylation analysis to evaluate the relationship of CpG methylation to differential gene expression. Among 485,577 loci, 5850 loci on 2282 genes showed significant differences between the 2 groups (delta-beta >10.

Gene profile of fibroblasts identify relation of CCL8 with idiopathic pulmonary fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is characterized by the complex interaction of cells involved in chronic inflammation and fibrosis. Global gene expression of a homogenous cell population will identify novel candidate genes.

Methods: Gene expression of fibroblasts derived from lung tissues (8 IPF and 4 controls) was profiled, and ontology and functional pathway were analyzed in the genes exhibiting >2 absolute fold changes with p-values < 0.

Functional recombinants designed from a fetuin/asialofetuin-specific marine algal lectin, rhodobindin.

Plant lectins have attracted much attention for biomedical applications including targeted drug delivery system and therapy against tumors and microbial infections. The main problem of using lectins as a biomedical tool is a batch-to-batch variation in isoforms content. The production of lectins using recombination tools has the advantage of obtaining high amounts of proteins with more precise properties, but there are only a handful of functional recombinant lectins presently available.

Angiotensin-converting enzyme (ACE) gene polymorphisms are associated with idiopathic pulmonary fibrosis.

Background: Idiopathic pulmonary fibrosis (IPF) is characterized by progressive dyspnea and worsening lung function. ACE is increased in the bronchoalveolar lavage fluid from patients with IPF, suggesting the role of ACE in the pathogenesis of IPF. We evaluated the role of single-nucleotide polymorphisms (SNPs) in the development risk of IPF.

Correlation between Frailty Level and Adverse Health-related Outcomes of Community-Dwelling Elderly, One Year Retrospective Study.

Background: Frailty is considered to be a clinical syndrome characterized by decreased physiological reserves associated with a greater risk of health-related problems, hospitalization, and death. The current study examined hospitalization, falls, cognitive decline and disability between robust, prefrail and frail elderly in one year.

Methods: 110 participants aged 65 or more who visited two senior welfare centers in Seoul from February 2008 to June 2008 were surveyed again from March 2009 to June 2009 with demographic characteristics, number of chronic diseases and medication, study of osteoporotic fractures (SOF) frailty index, instrumental activity of daily living (IADL), depression, mini-mental state examination-Korean version (MMSE-K), falling history and admission history within one year.

Desensitization of somatostatin-induced inhibition of low extracellular magnesium concentration-induced calcium spikes in cultured rat hippocampal neurons.

Neuronal excitability is inhibited by somatostatin, which might play important roles in seizure and neuroprotection. The possibility of whether the effect of somatostatin on neurotransmission is susceptible to desensitization was investigated. We tested the effects of prolonged exposure to somatostatin on 0.

Fluoxetine inhibits ATP-induced [Ca(2+)](i) increase in PC12 cells by inhibiting both extracellular Ca(2+) influx and Ca(2+) release from intracellular stores.

Fluoxetine, a widely used antidepressant, has additional effects, including the blocking of voltage-gated ion channels. We examined whether fluoxetine affects ATP-induced calcium signaling in PC12 cells using fura-2-based digital calcium imaging, an assay for [3H]-inositol phosphates (IPs) and whole-cell patch clamping. Treatment with ATP (100 microM) for 2 min induced increases in intracellular free Ca(2+) concentrations ([Ca(2+)](i)).
