Infants' sensitivity to emotional expressions in actions: The contributions of parental expressivity and motor experience.

Actions can convey information about the affective state of an actor. By the end of the first year, infants show sensitivity to such emotional information in actions. Here, we examined the mechanisms contributing to infants' developing sensitivity to emotional action kinematics.

A rare association of celiac disease and rectal neuroendocrine tumor.

Celiac disease (CD) is a chronic immune-mediated enteropathy which is triggered by dietary gluten in genetically predisposed individuals. Increased risk of all gastrointestinal cancers was found during the first year after diagnosis of CD. Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a heterogeneous tumor group originating from the diffuse neuroendocrine system.

Coexistence of two rare genetic disorders: Kartagener syndrome and familial Mediterranean fever.

Primary ciliary dyskinesia (PCD) is a rare disease, predominantly inherited as an autosomal recessive, with ciliary dysfunction leading to impaired mucociliary clearance, chronic airway infection and inflammation. Situs inversus totalis occurs in ~50 % of PCD patients and it is known as Kartagener syndome. Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent attacks of fever and peritonitis, pleuritis, arthritis, or erysipelas-like skin disease.

Coexistence of Multiple Endocrine Neoplasia Type 2B and Chilaiditi Sign: A Case Report.

We present a 15-year-old female patient with medullary thyroid carcinoma, marfanoid habitus, and mucosal ganglioneuromatosis. Our case had a RET protooncogene mutation ser836 polymorphism in exon 14 and ser904 polymorphism in exon 15. Our patient is thought to be atypical MEN2B due to the absence of M918T or A883F mutations.

High density single-molecule-bead arrays for parallel single molecule force spectroscopy.

The assembly of a highly parallel force spectroscopy tool requires careful placement of single-molecule targets on the substrate and the deliberate manipulation of a multitude of force probes. Since the probe must approach the target biomolecule for covalent attachment, while avoiding irreversible adhesion to the substrate, the use of polymer microspheres as force probes to create the tethered bead array poses a problem. Therefore, the interactions between the force probe and the surface must be repulsive at very short distances (<5 nm) and attractive at long distances.

Dielectrophoretic tweezers as a platform for molecular force spectroscopy in a highly parallel format.

We demonstrated the application of a simple electrode geometry for dielectrophoresis (DEP) on colloidal probes as a form of molecular force spectroscopy in a highly parallel format. The electric field between parallel plates is perturbed with dielectric microstructures, generating uniform DEP forces on colloidal probes in the range of several hundred piconewtons across a macroscopic sample area. We determined the approximate crossover frequency between negative and positive DEP using electrodes without dielectric microstructures-a simplification over standard experimental methods involving quadrupoles or optical trapping.
