Single-cell transcriptome conservation in cryopreserved cells and tissues
A variety of single-cell RNA preparation procedures have been described. So far, protocols require fresh material, which hinders complex study designs. We describe a sample preservation method that maintains transcripts ...
Induction of prophages by fluoroquinolones in streptococcus pneumoniae: implications for emergence of resistance in genetically-related clones
Antibiotic resistance in Streptococcus pneumoniae has increased worldwide by the spread of a few clones. Fluoroquinolone resistance occurs mainly by alteration of their intracellular targets, the type II DNA topoisomerases, ...
Identification of polysaccharide capsules among extensively drug-resistant genitourinary Haemophilus parainfluenzae isolates
The human commensal Haemophilus parainfluenzae is emerging as an opportunistic multidrug-resistant pathogen. The objectives of this work were to characterise a new capsular operon of extensively drug-resistant (XDR) H. ...
Membrane Omega-3 Fatty Acids Modulate the Oligomerisation Kinetics of Adenosine A2A and Dopamine D2 Receptors.
Membrane levels of docosahexaenoic acid (DHA), an essential omega-3 polyunsaturated fatty acid (ω-3 PUFA), are decreased in common neuropsychiatric disorders. DHA modulates key cell membrane properties like fluidity, thereby ...
Altered distribution of RhoA in alzheimer's disease and AβPP overexpressing mice
RhoGTPases control cytoskeleton dynamics thereby modulating synaptic plasticity. Because Alzheimer's disease (AD) is characterized by synaptic dysfunction, we sought to determine whether the expression, activity, or ...
Antibiotic prescription in the treatment of odontogenic infection by health professionals: a factor to consensus
Objective: To observe the attitude of dentists and family doctors in prescribing antibiotics for the treatment of dental infections. Study Design: A poll was performed to determine the differences in the prescription of ...
Inflammation in Lafora Disease: evolution with disease progression in laforin and malin knock-out mouse models
Lafora progressive myoclonus epilepsy (Lafora disease, LD) is a fatal rare autosomal recessive neurodegenerative disorder characterized by the accumulation of insoluble ubiquitinated polyglucosan inclusions in the cytoplasm ...
Severe alterations in lipid composition of frontal cortex lipid rafts from parkinson's disease and incidental parkinson's
Lipid rafts are cholesterol- and sphingomyelin-enriched microdomains that provide a highly saturated and viscous physicochemical microenvironment to promote protein-lipid and protein-protein interactions. We purified lipid ...
G protein-coupled receptor 37 (GPR37) emerges as an important modulator of adenosinergic transmission in the striatum
G protein-coupled receptor 37 (GPR37), also known as parkin associated endothelin-like (Pael) receptor, is an orphan G protein-coupled receptor, which suffers a defective parking ubiquitination in autosomal recessive ...
Astrogliopathy in tauopathies
Astrocytes are involved in many diseases of the central nervous system, not only as reactive cells to neuronal damage but also as primary actors in the pathological process. Astrogliopathy is a term used to designate the ...
Comprehensive establishment and characterization of orthoxenograft mouse models of malignant peripheral nerve sheath tumors for personalized medicine
Malignant peripheral nerve sheath tumors (MPNSTs) are soft-tissue sarcomas that can arise either sporadically or in association with neurofibromatosis type 1 (NF1). These aggressive malignancies confer poor survival, with ...
Analysis of SLX4/FANCP in non-BRCA1/2-mutated breast cancer families
Background: Genes that, when mutated, cause Fanconi anemia or greatly increase breast cancer risk encode for proteins that converge on a homology-directed DNA damage repair process. Mutations in the SLX4 gene, which encodes ...
Trehalose polyphleates, external cell wall lipids in mycobacterium abscessus, are associated with the formation of clumps with cording morphology, which have been associated with virulence
Mycobacterium abscessus is a reemerging pathogen that causes pulmonary diseases similar to tuberculosis, which is caused by Mycobacterium tuberculosis. When grown in agar medium, M. abscessus strains generate rough (R) or ...
Experimental study of clinafloxacin alone and in combination in the treatment of ciprofloxacin-susceptible and -resistant pneumococcal meningitis
The increasing incidence of ciprofloxacin resistance in Streptococcus pneumoniae may limit the efficacy of the new quinolones in difficult-to-treat infections such as meningitis. The aim of the present study was to determine ...
Multicenter study of plastic vs. self-expanding metal stents in endoscopic ultrasound-guided drainage of walled-off pancreatic necrosis - PROMETHEUS: a randomized controlled trial protocol.
Background: It seems that lumen-apposing metal stents (LAMS) are displacing plastic stents in the therapy of pancreatic-fluid collection in walled-off necrosis (WON). To date, there is no quality of evidence to recommend ...
Diagnostic accuracy of prion disease biomarkers in iatrogenic Creutzfeldt-Jakob disease
Human prion diseases are classified into sporadic, genetic, and acquired forms. Within this last group, iatrogenic Creutzfeldt-Jakob disease (iCJD) is caused by human-to-human transmission through surgical and medical ...
Unexpected expression of alpha- and beta-globin in mesencephalic dopaminergic neurons and glial cells
The mesencephalic dopaminergic (mDA) cell system is composed of two major groups of projecting cells in the substantia nigra (SN) (A9 neurons) and the ventral tegmental area (VTA) (A10 cells). A9 neurons form the nigrostriatal ...
Resistance to penicillin and cephalosporin and mortality from severe pneumococcal pneumonia in Barcelona, Spain
Background: Penicillin-resistant strains of Streptococcus pneumoniae are now found worldwide, and strains with resistance to cephalosporin are being reported. The appropriate antibiotic therapy for pneumococcal pneumonia ...
Adenosine receptor heteromers and their integrative role in striatal function
By analyzing the functional role of adenosine receptor heteromers, we review a series of new concepts that should modify our classical views of neurotransmission in the central nervous system (CNS). Neurotransmitter receptors ...
Deregulation of purine metabolism in Alzheimer's disease
The neuroprotective role of adenosine and the deregulation of adenosine receptors in Alzheimer's disease (AD) have been extensively studied in recent years. However, little is known about the involvement of purine metabolism ...
