The patient's diet has been considered an important etiological factor of dentin hypersensitivity. The frequent ingestion of acidic substances can promote the loss of dental structure or remove the smear layer. The purpose of this study was to evaluate the degree of smear layer removal and dentinal tubules exposure by different natural orange juices. Extracted human teeth were submitted to manu...

Foods that are high in citrate content generally are assumed to deliver alkali load when consumed irrespective of the accompanying cation. The object of this randomized, crossover study was to compare the effects of orange juice with those of lemonade on acid-base profile and urinary stone risks under controlled metabolic conditions. Thirteen volunteers (nine healthy subjects and four stone for...

It has been said that the color of sputum from patients with Legionella pneumophila pneumonia is orange. However, why the color is orange has not been clarified. First, orange-colored sputum obtained from a patient with L. pneumophila pneumonia is presented. Then, the formation of an orange-colored pigment in a culture medium (without charcoal) after the growth of L. pneumophila is demonstrated.

In the guppy Poecilia reticulata, males exhibit orange spots on their body and tail, and the orange spot patterns are often criteria of female mate choice. The orange spot coloration of the males is determined by the intake of algae, a natural source of carotenoids. Therefore, it is considered that males exhibiting conspicuous orange coloration possess high algal-foraging ability. In the presen...

The computer graphic simulation of a common spray painting artifact, called orange peel, is discussed. Orange peel distorts surface reflections and is commonplace in product design applications. The orange peel measurements from a standard industrial instrument are used to construct a height field, and this surface is rendered using traditional normal mapping techniques. Comparisons are made be...

Hepatitis C virus (HCV) replication requires binding of the liver-specific microRNA (miRNA) miR-122 to two sites in the HCV 5' untranslated region (UTR). Although we and others have shown that viral genetics impact the amount of active miR-122 required for replication, it is unclear if HCV can replicate in the complete absence of this miRNA. To probe the absolute requirements for miR-122 and th...

OBJECTIVE To investigate the effects of microRNA-122 (miR-122) on proliferation, migration, and invasion in human hepatocellular carcinoma (HCC) cells by activating epithelial-mesenchymal transition (EMT) pathways. METHODS miR-122 mimics, miR-122 inhibitors, relevant control oligonucleotides, and Wnt1 were transfected into HepG2 and huh7 cell lines which were then divided into six groups: miR...

Our study investigated whether microRNA-122 (miR-122) played important roles in the proliferation, invasion and apoptosis of human cholangiocarcinoma (CC) cells. QBC939 and RBE cells lines were chosen and divided into five groups: miR-122 mimic group, anti-miR-122 group, negative control (NC) group, mock group and blank group. MiR-122 expression was measured by qRT-PCR. Roles of miR-122 in cell...
