Background: Occipital cervical fixation (OCF) is an important and difficult technic and has certain risks due to its relation with adjacent special anatomic features. One of specific areas to perform screw fixation and to prevent technical failures is the thickness of the occipital bone which require detailed morphological anatomical knowledge. To our knowledge, no published study has provided ...

Varghese E, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220506 Description Occipital spurs, also called as occipital knob, occipital bun, chignon or inion hook, is an exaggerated external occipital protuberance (EOP). It is frequently discussed in anthropological literature as a Neanderthal trait but hardly reported and considered as a normal variant in medical literature. It is a frequent f...

Abstract Background The esophagus involvement in systemic sclerosis (SSc) is very common yet underestimated due to the lack of suitable screening tools. This study aims explore usefulness ultrasound (US) assessment and identify its relationship with clinical CT manifestations. Methods We performed transabdominal esophageal US 38 SSc patients controls. parameters including abdominal length, wall...

Oxidoreductases of the thioredoxin superfamily possess the C-X-X-C motif. The redox potentials vary over a wide range for these proteins. A crucial determinant of the redox potential has been attributed to the variation of the X-X dipeptide. Here, we substitute Lys for Gly at the first X of Escherichia coli thioredoxin to investigate how a positive charge would affect the redox potential. The s...

BACKGROUND Many patients ask for advice about choosing a pillow. This research was undertaken to determine if pillow type alters cervico-thoracic spine position when resting in the side-lying position. AIM To investigate the effect of different pillow shape and content on the slope of cervico-thoracic spine segments when side lying. MATERIALS AND METHODS The study was a randomized blinded c...

A novel bacteriophage defense system, based on an inducible suicide gene, was challenged with a lactococcal bacteriophage to investigate the potential for phage adaptation. The defense system was encoded by pTRK414H, a high-copy-number replicon encoding a tightly regulated phi 31p trigger promoter fused to the lethal LlaIR+ restriction endonuclease cassette. Repeated transfers of Lactococcus la...

The serotype b-specific carbohydrate antigen (SbAg) of Actinobacillus actinomycetemcomitans Y4 is reported to be the O antigen of lipopolysaccharide, and the highest titers of serum antibody reactive with A. actinomycetemcomitans in early-onset periodontitis (EOP) patients bind SbAg. These high titers of serum antibody reactive with SbAg are associated with a lesser extent and severity of perio...
