In modern bioanalytics, elemental analysis of single cells is important yet challenging due to the complicated biological matrices and elemental contents. We have developed the high irradiance femtosecond laser ionization orthogonal time-of-flight mass spectrometry (fs-LI-O-TOFMS) to determine the elemental composition of individual cells. The sample preparation procedure is simple and ...

Context.-Lung carcinoma is the result of sequential accumulation of genetic and epigenetic changes. Lung adenocarcinoma is a heterogeneous disease with diverse somatic mutations, and several of them include the so-called driver mutations, which may serve as "druggable" therapeutic targets. Thus, development of personalized approaches for the treatment of non-small cell ...

SUMMARY:: Neonatal EEG can be useful for predicting outcome soon after acute hypoxia-ischemia. There are techniques that can optimize the prognostic accuracy of EEG. Seizure medications and the time interval between hypoxia-ischemia and the EEG must be taken into account. Serial EEGs also improve the predictive ability of EEG.

We theoretically investigate and optimize a multilayer planar structure with enhanced magneto-optical (MO) activity. The extraordinary optical transmission observed in a periodically perforated metal plate with subwavelength holes is used to produce a higher MO activity. We consider a three-layer structure that consists of a dielectric layer placed between the ...

In this article, we report detection of deformable, hydrogel particles by the resistive-pulse technique using single pores in a polymer film. The hydrogels pass through the pores by electroosmosis and cause formation of a characteristic shape of resistive pulses indicating the particles underwent dehydration and deformation. These effects were explained ...

We introduce a novel ageism scale, focusing on prescriptive beliefs concerning potential intergenerational tensions: active, envied resource succession, symbolic identity avoidance, and passive, shared-resource consumption (SIC). Four studies (2,010 total participants) were used to develop the scale. Exploratory factor analysis formed an initial 20-item, 3-factor solution (Study 1). The scale ...

In many decision making tasks negative feedback is probabilistic and, as a consequence, may be given when the decision is actually correct. This feedback can be referred to as nonrepresentative negative feedback. In the current study, we investigated developmental and gender related differences in such switching after nonrepresentative negative feedback. ...

TRIC channel subtypes form bullet-shaped homo-trimeric assemblies and behave as K (+) channels in intracellular membrane systems. The pathophysiological defects observed in knockout mice suggest that TRIC channels mediate counter-K (+) movements to facilitate Ca(2 +) release from intracellular stores in various cell types. In vascular smooth muscle cells (VSMCs) ...

We study the dynamics of oscillating discrete solitons in an array of coupled Kerr-nonlinear cavities. They emanate from stationary discrete cavity solitons due to Hopf instability and are very robust. We show that these oscillating solitons can spontaneously lose their spatial symmetry and start rocking around the equilibrium position. Moreover ...
