Usefulness of betalactam therapy for community-acquired pneumonia in the era of drug-resistant Streptococcus pneumoniae: a randomized study of amoxicillin-clavulanate and ceftriaxone
Empirical antibiotic therapy of community-acquired pneumonia (CAP) has been complicated by the worldwide emergence of penicillin resistance among Streptococcus pneumoniae. The impact of this resistance on the outcome of ...
BS-SEM evaluation of the tisular interactions between cortical bone and calcium-phosphate covered titanium implants
The improvement of the reliability of the contact between the osseous tissues and the implant materials has been tested by recovering the metallic implants with ceramic materials, usually calcium phosphates. In our study, ...
Decrease of invasive pneumococcal disease (IPD) in adults after introduction of pneumococcal 13-valent conjugate vaccine in Spain
A prospective laboratory-based multicenter study that collected all adult invasive pneumococcal disease (IPD) episodes from 6 Spanish hospitals before (2008-2009) and after (2012-2013). The 13-valent pneumococcal conjugate ...
Olfactory receptors in non-chemosensory organs: the nervous system in health and disease
Olfactory receptors (ORs) and down-stream functional signaling molecules adenylyl cyclase 3 (AC3), olfactory G protein α subunit (Gαolf), OR transporters receptor transporter proteins 1 and 2 (RTP1 and RTP2), receptor ...
Imaging mass spectrometry (IMS) of cortical lipids from preclinical to severe stages of Alzheimer's disease
Alzheimer's disease (AD) is a progressive neurodegenerative disease affecting millions of patients worldwide. Previous studies have demonstrated alterations in the lipid composition of lipid extracts from plasma and brain ...
Poly(propylene imine) dendrimers with histidine-maltose shell as novel type of nanoparticles for synapse and memory protection
Poly(propylene imine) dendrimers have been shown to be promising 3-dimensional polymers for the use in the pharmaceutical andbiomedical applications. Our aims of this study were first, to synthesize a novel type of dendrimer ...
Ultrasound of distal brachialis tendon attachment: normal and abnormal findings
Objective: To demonstrate normal and abnormal findings of distal brachialis tendon attachment in cadavers, normal volunteers and patients by means of ultrasound. Methods: 3 cadaveric specimens, 30 normal volunteers and 125 ...
The HERC2 ubiquitin ligase is essential for embryonic development and regulates motor coordination
A mutation in the HERC2 gene has been linked to a severe neurodevelopmental disorder with similarities to the Angelman syndrome. This gene codifies a protein with ubiquitin ligase activity that regulates the activity of ...
Clinical and myopathological evaluation of early- and late-onset subtypes of myofibrillar myopathy
Myofibrillar myopathies (MFM) are a group of disorders associated with mutations in DES, CRY A B, M YOT, ZASP, FLNC, or BAG3 genes and characterized by disintegration of myofibrils and accumulation of degradation products ...
Diagnosis of prodromal and Alzheimer's disease dementia in adults with Down syndrome using neuropsychological tests
Introduction: We aimed to define prodromal Alzheimer's disease (AD) and AD dementia using normative neuropsychological data in a large population-based cohort of adults with Down syndrome (DS). Methods: Cross-sectional ...
Telomere length and genetic anticipation in lynch syndrome
Telomere length variation has been associated with increased risk of several types of tumors, and telomere shortening, with genetic anticipation in a number of genetic diseases including hereditary cancer syndromes. No ...
Ras-association domain of sorting nexin 27 is critical for regulating expression of GIRK potassium channels
G protein-gated inwardly rectifying potassium (GIRK) channels play an important role in regulating neuronal excitability. Sorting nexin 27b (SNX27b), which reduces surface expression of GIRK channels through a PDZ domain ...
A Regenerative Endodontic Approach in Mature Ferret Teeth Using Rodent Preameloblast-conditioned Medium
Background: This study evaluated the effectiveness of a regenerative endodontic approach to regenerate the pulp tissue in mature teeth of ferret. The presence of odontoblast-like cells in the newly-formed tissue of teeth ...
A mouse peritonitis model for the study of glycopeptide efficacy in GISA infections
In recent years, the emergence of Staphylococcus aureus strains with reduced susceptibility to glycopeptides has raised considerable concern. We studied the efficacy of vancomycin and teicoplanin, as well as cloxacillin ...
PBF509, an adenosine A(2A) receptor antagonist with efficacy in rodent models of movement disorders
Adenosine A2A receptor (A2AR) antagonists have emerged as complementary non-dopaminergic drugs to alleviate Parkinson's disease (PD) symptomatology. Here, we characterize a novel non-xhantine non-furan A2AR antagonist, ...
Sobre tránsitos, identidades y crecimiento postraumático en cáncer hereditario
A lo largo de la historia de la psico-oncología los conceptos de personalidad e identidad de los pacientes oncológicos se han utilizado frecuentemente tanto para explicar la aparición de la enfermedad como los cambios ...
A common BACE1 polymorphism is a risk factor for sporadic Creutzfeldt-Jakob disease
The β site APP cleaving enzyme 1 (BACE1) is the rate-limiting β-secretase enzyme in the amyloidogenic processing of APP and Aβ formation, and therefore it has a prominent role in Alzheimer"s disease (AD) pathology. Recent ...
The role of fibroblast growth factor (FGF) and type beta transforming growth factot beta (TGF beta1, beta2 and beta3) during rat craniofacial development
Growth factors seem to be part of a complex cellular signalling language, in which individual growth factors are the equivalents of the letters that compose words. According to this analogy, informational content lies, not ...
Neuronal pentraxin 1 contributes to the neuronal damage evoked by amyloid-beta and is overexpressed in dystrophic neurites in alzheimer's brain
Accumulation of amyloid-beta (Abeta) is thought to play a central role in the progressive loss of synapses, the neurite damage, and the neuronal death that are characteristic in brains affected by Alzheimer's disease. ...
Amyloid and tau pathology of familial Alzheimer's disease APP/PS1 mouse model in a senescence phenotype background (SAMP8)
The amyloid precursor protein/presenilin 1 (APP/PS1) mouse model of Alzheimer's disease (AD) has provided robust neuropathological hallmarks of familial AD-like pattern at early ages, whereas senescence-accelerated mouse ...
