External irradiation of advanced head and neck cancer often includes the major salivary glands, despite them not being affected by the disease. The aim of this study was to determine neuron-specific enolase (NSE) as a marker of inflammation in irradiated and non-irradiated salivary glands of the rat. This study shows that NSE expression in irradiated salivary glands is dependent on the topograp...

The multiplicity of metal-free (Population III) stars may influence their feedback efficiency within host dark matter halos, affecting subsequent metal enrichment and the transition to galaxy formation. Radiative from massive can trigger nearby star formation in dense self-shielded clouds. In model radiation self-shielding, H$_2$ column density must be accurately computed. this study, we compar...

Artificial neural networks (ANNs) have been promising tools for many applications. In recent years, a computer-aided design approach based on (ANNs) has been introduced to microwave modelling, simulation and optimization. In this work, the characteristic parameters of top shielded multilayered coplanar waveguides (CPWs) have been determined with the use of ANN models. These neural models were t...

An experiment tested the hypothesis that water exposed to distant intentions affects the aesthetic rating of ice crystals formed from that water. ?1 Over three days, 1,900 people in Austria and Germany focused their intentions towards water samples located inside an electromagnetically shielded room in California. Water samples located near the target water, but unknown to the people providing ...

OBJECTIVE To define the cytotoxicity of a photo-cured composite when used as a bonding system under a composite inlay. METHODS Composite specimens were photo-cured with or without a 2 mm composite inlay interposed between them and the light source. Samples were extracted in complete cell culture medium and the obtained eluates applied to primary cultures of human pulp and gingival fibroblasts...

Formulation of short interfering RNA (siRNA) into multicomponent lipid nanoparticles (LNP) is an effective strategy for hepatic delivery and therapeutic gene silencing. This study systematically evaluated the effect of polyethylene glycol (PEG) density on LNP physicochemical properties, innate immune response stimulation, and in vivo efficacy. Increased PEG density not only shielded LNP surface...
