Emerging, non-PCV13 serotypes 11A and 35B of Streptococcus pneumoniae show high potential for biofilm formation in vitro
Background: Since the use of pneumococcal conjugate vaccines PCV7 and PCV13 in children became widespread, invasive pneumococcal disease (IPD) has dramatically decreased. Nevertheless, there has been a rise in incidence ...
Neoadjuvant therapy in robotic lung surgery: elevating surgical complexity without compromising outcomes
Background: Neoadjuvant therapy, particularly the combination of chemotherapy and immunotherapy, has become standard in treating locally advanced non-small cell lung cancer (NSCLC). While this approach improves pathologic ...
Absence of nuclear p16 is a diagnostic and independent prognostic biomarker in squamous cell carcinoma of the cervix
The tumor-suppressor protein p16 is paradoxically overexpressed in cervical cancer (CC). Despite its potential as a biomarker, its clinical value and the reasons for its failure in tumor suppression remain unclear. Our ...
Low prevalence of Cfr-mediated linezolid resistance among methicillin-resistant Staphylococcus aureus in a Spanish hospital: case report on linezolid resistance acquired during linezolid therapy
Linezolid is an effective antimicrobial agent to treat methicillin-resistant Staphylococcus aureus (MRSA). Resistance to linezolid due to the cfr gene is described worldwide. The present study aimed to analyze the prevalence ...
CB2 Cannabinoid Receptor Agonist Ameliorates Alzheimer-Like Phenotype in AβPP/PS1 Mice
The specific CB2 cannabinoid receptor agonist JWH-133 induced cognitive improvement in double AβPP/PS1 transgenic mice, a genetic model of Alzheimer's disease. This effect was more pronounced when administered at the ...
Cromogranina A en adenomas hipofisarios humanos
Introducción: Las cromograninas son proteínas extensamente distribuidas en el sistema neuroendocrino, y su expresión puede usarse en la caracterización de los tumores neuroendocrinos. Material y métodos: Este estudio analiza ...
Hemoglobin mRNA Changes In The Frontal Cortex Of Patients With Neurodegenerative Diseases
Background: Hemoglobin is the major protein found in erythrocytes, where it acts as an oxygen carriermolecule. In recent years, its expression has been reported also in neurons and glial cells, although its role in brain ...
Early and gender-specific differences in spinal cord mitochondrial function and oxidative stress markers in a mouse model of ALS
Introduction: Amyotrophic lateral sclerosis (ALS) is a motor neuron disease with a gender bias towards major prevalence in male individuals. Several data suggest the involvement of oxidative stress and mitochondrial ...
Tau hyperphosphorylation induces oligomeric insulin accumulation and insulin resistance in neurons
Insulin signalling deficiencies and insulin resistance have been directly linked to the progression of neurodegenerative disorders like Alzheimer's disease. However, to date little is known about the underlying molecular ...
Lung endothelial cells are sensitive to epsilon toxin from Clostridium perfringens
The pore‐forming protein epsilon toxin (Etx) from Clostridium perfringens produces acute perivascular edema affecting several organs, especially the brain and lungs. Despite the toxin evident effect on microvasculature and ...
Characterization of nontypable haemophilus influenzae isolates recovered from adult patients with underlying chronic lung disease reveals genotypic and phenotypic traits associated with persistent infection

Globular glial tauopathies (GGT): consensus recommendations
Recent studies have highlighted a group of 4-repeat (4R) tauopathies that are characterised neuropathologically by widespread, globular glial inclusions (GGIs). Tau immunohistochemistry reveals 4R immunoreactive globular ...
Adenosine A1-A2A receptor-receptor interaction: contribution to guanosine-mediated effects
Guanosine, a guanine-based purine nucleoside, has been described as a neuromodulator that exerts neuroprotective effects in animal and cellular ischemia models. However, guanosine's exact mechanism of action and molecular ...
Sporadic Creutzfeldt-Jakob disease with glial PrPRes nuclear and perinuclear immunoreactivity
Proteinase K-resistant prion protein (PrPRes ) nuclear and perinuclear immunoreactivity in oligodendrocytes of the frontal cortex is found in one case of otherwise typical sporadic Creutzfeldt-Jakob disease (sCJD) type ...
Prevalence and molecular characterization of methicillin-resistant S. aureus ST398 resistant to tetracycline at a Spanish hospital over 12 years
Methicillin-resistant Staphylococcus aureus (MRSA) ST398, associated with livestock animals, was described in 2003 as a new lineage infecting or colonizing humans. We evaluated the prevalence and molecular characteristics ...
Altered machinery of protein synthesis in Alzheimer's: from the nucleolus to the ribosome
Ribosomes and protein synthesis have been reported to be altered in the cerebral cortex at advanced stages of Alzheimer's disease (AD). Modifications in the hippocampus with disease progression have not been assessed. ...
A signaling mechanism coupling netrin-1/deleted in colorectal cancer chemoattraction to SNARE-mediated exocytosis in axonal growth cones
Directed cell migration and axonal guidance are essential steps in neural development. Both processes are controlled by specific guidance cues that activate the signaling cascades that ultimately control cytoskeletal ...
A novel form of human disease with a protease-sensitive prion protein and heterozygosity methionine/valine at codon 129: Case report
Background: Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare neurodegenerative disorder in humans included in the group of Transmissible Spongiform Encephalopathies or prion diseases. The vast majority of sCJD cases are ...
PDR-1/hParkin negatively regulates the phagocyosis of apoptotic cell corpses in Caenorhabditis elegans
Apoptotic cell death is an integral part of cell turnover in many tissues, and proper corpse clearance is vital to maintaining tissue homeostasis in all multicellular organisms. Even in tissues with high cellular turnover, ...
Minimal RB-responsive E1A Promoter Modification to Attain Potency, Selectivity, and Transgene-arming Capacity in Oncolytic Adenoviruses
Oncolytic adenoviruses are promising anticancer agents due to their ability to self-amplify at the tumor mass. However, tumor stroma imposes barriers difficult to overcome by these agents. Transgene expression is a valuable ...
