Sexual behavior can be usefully parsed into an appetitive and a consummatory component. Both appetitive and consummatory male-typical sexual behaviors (respectively, ASB and CSB) are activated in male Japanese quail by testosterone (T) acting in the medial preoptic nucleus (POM), but never observed in females. This sex difference is based ...

ABSTRACT: Water soluble amphiphilic chitosan nanocarriers tethered with the photosensitizer meso-tetraphenylporphyrin were synthesized, in a seven step procedure, starting from 3,6-di-O-tert-butyldimethylsilyl-chitosan and 5-(p-aminophenyl)-10,15,20-triphenylporphyrin. The lipophilic photosensitizer could be introduced in a quantitative and reproducible reaction to give either 0.1 or 0.25 degree of substitution per glucosamine monomer. Fluorescence and NMR ...

There is evidence suggesting that immunosenescence can be accelerated by external factors such as chronic stress. Here we review potential psychoneuroendocrine determinants of premature aging of the immune system and discuss available interventions aimed at attenuating immunosenescence. Chronic stress may accelerate various features of immunosenescence by activating key allostatic systems, ...

Mono- and multispecies microbial populations alter the chemistry of their surrounding environments during colony development thereby influencing multicellular behavior and interspecies interactions of neighboring microbes. Here we present a methodology that enables the creation of three-dimensional (3D) models of a microbial chemotype that can be correlated to the colony phenotype ...

Triarylsulfonium hexafluorophosphate salts were shown to be effective catalysts for the ring-opening polymerisation of various cyclic monomers under UV irradiation. A dual basic/acidic catalytic system demonstrated the potential for UV-triggered formation of poly(δ-valerolactone)-b-poly(l-lactide)-b-poly(δ-valerolactone) in a 'one-pot' reaction.

Recent human behavioral studies have shown semantic and/or lexical processing for stimuli presented below the auditory perception threshold. Here, we investigated electroencephalographic responses to words, pseudo-words and complex sounds, in conditions where phonological and lexical categorizations were behaviorally successful (categorized stimuli) or unsuccessful (uncategorized stimuli). Data showed a greater decrease ...

KEY MESSAGE : There are multiple publications on Anthurium transformation, yet a commercial product has not been achieved. This may be due to use of non-optimum promoters here we address this problem. Different promoters and tissue types were evaluated for transient β-glucuronidase (GUS) expression in Anthurium andraeanum Hort. 'Marian Seefurth' ...

The association between schizophrenia and cancer risks is controversial in the clinical and epidemiological literature. Studies from different populations, tumor sites, or health care systems have provided inconsistent findings. In the present study, we examine a less well-investigated hypothesis that age plays a crucial role in cancer risks in schizophrenia. ...

A Gd(2)SiO(5) (GSO) tweezers-type coincidence detector was developed and tested for tumor detection in procedures such as (18)F-fluorodeoxyglucose (FDG)-guided surgery. The detector consists of a pair of GSO scintillators, a pair of metal-packaged small-sized photomultiplier tubes (PMTs), and a coincidence circuit. Because the GSO scintillators are located on the tips ...

The transient existence of π-allyl-palladium intermediates formed by the reaction of Pd(OAc)(2) and anisole-derived meta photocycloadducts has been demonstrated using NMR techniques. The intermediates tended to be short-lived and underwent rapid reductive elimination of palladium metal to form allylic acetates, however this degradation process could be delayed by changing the ...

The concept of neuroprotective autoimmunity implies that immune cells, especially autoantigen-specific T cells, infiltrate the central nervous system (CNS) after injury and contribute to neuroregeneration and repair by secreting soluble factors. Amongst others, neurotrophic factors and neurotrophins such as brain-derived neurotropic factor (BDNF) are considered to play an important role ...

Cartilage defects can be addressed with replacement strategies such as autologous chondrocyte implantation (ACI). Expansion of autologous chondrocytes in vitro is an essential step to obtain the necessary cell numbers required for ACI. A major problem with this approach is dedifferentiation of chondrocytes during expansion, resulting in cells with fibroblast-like ...

Multi-helical DNA-silica fibers were synthesised by the self-assembly of DNA molecules with cationic organosilanes and silica sources. By electron microscopy images and circular dichroism spectra, three-level helical structures in the silica fibers have been revealed, i.e. the DNA double-helix, the secondary left-handed DNA packing and the tertiary right-handed twisting.

Recent studies indicate that the primary somatosensory cortex (S1) is active not only when touch is physically perceived but also when it is merely observed to be experienced by another person. This social responsivity of S1 has important implications for our understanding of S1 functioning. However, S1 activity during touch ...

ABSTRACT: BACKGROUND: A proline-to-serine substitution at position-56 (P56S) of vesicle-associated membrane protein-associated protein B (VAPB) causes a form of dominantly inherited motor neuron disease (MND), including typical and atypical amyotrophic lateral sclerosis (ALS) and a mild late-onset spinal muscular atrophy (SMA). VAPB is an integral endoplasmic reticulum (ER) protein and ...

In cells, the levels of sterol vary greatly among organelles. This uneven distribution depends largely on non-vesicular routes of transfer, which are mediated by soluble carriers called lipid-transfer proteins (LTPs). These proteins have a domain with a hydrophobic cavity that accommodates one sterol molecule. However, a demonstration of their role ...

In many odontological studies concerning archeological material, there is no analysis of early caries lesions (caries incipiens) that manifest as a carious spot. At this stage of caries, the enamel is still hard, and thus, it is impossible to diagnose caries by visual methods. We assessed the usefulness of the ...

ABSTRACT: BACKGROUND: The physiological function of p38alpha, which is an isoform of p38 MAPK, has been investigated previously in several studies using pharmacological inhibitors. However, the results regarding whether p38alpha promotes or inhibits nerve regeneration in vivo have been controversial. METHODS: We generated novel p38alpha mutant mice (sem mice) with ...

Galactoglucomannan oligosaccharides seem to interact with auxin in xylogenic cell culture, thus influencing mainly metaxylem-like tracheary element differentiation depending on timing with hormones and the process kinetics. Complex mapping of Zinnia mesophyll cell transdifferentiation into tracheary elements with or without prior cell division was documented after palisade and spongy parenchyma ...
