Acquisition of temozolomide (TMZ) resistance is a major factor leading to the failure of glioblastoma (GBM) treatment. The exact mechanism by which GBM evades TMZ toxicity is not always related to the expression of the DNA repair enzyme O(6)-methylguanine-DNA methyltransferase (MGMT), and so remains unclear. In this study, TMZ-resistant variants derived from MGMT-negative GBM clinical samples and cell lines were studied, revealing there to be increased specificity protein 1 (Sp1) expression associated with reduced reactive oxygen species (ROS) accumulation following TMZ treatment...

Chill susceptible insects suffer tissue damage and die at low temperatures. The mechanisms that cause chilling injury are not well understood but a growing body of evidence suggests that a cold-induced loss of ion and water homeostasis leads to hemolymph hyperkalemia that depolarizes cells, leading to cell death. The apparent root of this cascade is the net leak of osmolytes down their concentration gradients in the cold. Many insects, however, are capable of adjusting their thermal physiology, and cold-acclimated Drosophila can maintain homeostasis and avoid injury better than warm-acclimated flies...

Cardiac hypertrophy and associated heart fibrosis remain a major cause of death worldwide. Phytochemicals have gained attention as alternative therapeutics for managing cardiovascular diseases. These include the extract from the plant Terminalia arjuna which is a popular cardioprotectant and may prevent or slow progression of pathological hypertrophy to heart failure. Here, we investigated the mode of action of a principal bioactive T. arjuna compound, arjunolic acid (AA) in ameliorating hemodynamic load-induced cardiac fibrosis and identified its intracellular target...

AIMS: Diagnostic ambiguities regarding the malignant potentiality of oral submucous fibrosis (OSF), an oral precancerous condition having dysplastic and non-dysplastic isoforms are the major failure for early intervention of oral squamous cell carcinoma (OSCC) patients. Our goal is to identify proteomic signatures from biopsies that can be used as precancer diagnostic marker for patient suffering from OSF. METHODS: The high throughput techniques adopting de novo peptide sequencing (1D SDS-PAGE coupled nanoLC MALDI tandem mass spectrometry (MS/MS)-based peptide mass fingerprint), immunohistochemistry (IHC), Western blot (WB) and real-time PCR (RT-PCR) analysis are considered for such biomarker identification and multilevel validations...

Ribosomopathies comprise a heterogeneous group of hematologic and developmental disorders, often characterized by bone marrow failure, skeletal and other developmental abnormalities and cancer predisposition. They are associated with mutations and/or haplo-insufficiencies of ribosomal proteins (RPs) and inefficient ribosomal RNA (rRNA) processing. The resulting ribosomal stress induces the canonical p19ARF/Mdm2/p53 tumor suppressor pathway leading to proliferative arrest and/or apoptosis. It has been proposed that this pathway is then inactivated during subsequent neoplastic evolution...

Non invasive ventilation (NIV) has a well established role in the treatment of acute-on-chronic respiratory failure and cardiogenic pulmonary oedema. Its role in acute hypoxaemic respiratory failure has been increasingly investigated, but its impact on the management and the outcome of the subset of patients affected by acute respiratory distress syndrome (ARDS) is still to be determined. ARDS could be a risk factor for NIV failure and in these patient delayed endotracheal intubation can lead to an increased mortality...

Thromboembolic events, principally stroke, represent among the leading causes of morbidity and mortality of subjects with atrial fibrillation, with an incidence about 5 times higher compared to healthy subjects. Chronic kidney disease, frequently associated with atrial fibrillation, determines itself a further increase of thromboembolic events, bleeding and mortality. In addition, the presence of renal failure complicates the pharmacological management of these patients, mainly due to the side effects of antiarrhythmic and anticoagulant drugs with renal excretion, due to their accumulation...

Ebola virus (EBOV) was discovered for the first time in 1976. It belongs to the family Filoviridae, which causes hemorrhagic fever that could lead to death in a few days. West Africa faced a major outbreak where symptoms appeared in the form of chills, myalgia, fever, diarrhea, and vomiting, and the disease finally reached a severe state as a result of hemorrhagic complications and failure of multiple organs. EBOV spreads by contact with body fluids of an infected person such as blood, saliva, urine, and seminal fluid, and also spreads by a contact with contaminated surfaces...

Thoracic myelopathy is often caused by vertebral body fractures resulting from neoplastic conditions, traumatic events, or infectious diseases. One of the preferred procedures for treating it is the lateral extracavitary approach (LECA) with single-level or multilevel decompressive corpectomy and reconstruction. The aim of this retrospective study was to analyze the thoracic lateral extracavitary approach with corpectomy using vertebral body replacement systems (VBR-S) and dorsal reconstruction. Twenty-four patients with metastatic or primary lesions of thoracic vertebrae T2-T12 underwent spinal decompression and ventral column reconstruction with correction of spinal deformity via a LECA...

INTRODUCTION: Intra-aortic balloon pump (IABP) counterpulsation is a catheter-based treatment for coronary artery disease and decompensated heart failure to increase coronary blood flow and improve cardiac output. IABP is generally well tolerated, and complications are usually related to peripheral vasculature or red blood cell and platelet consumption. The usual insertion site via femoral artery renders the patient bedbound. Recently, axillary artery has been used in patients with atherosclerotic peripheral vascular disease and documented small arteries or in those awaiting transplant to ensure ambulation and prevent deconditioning...

The honey bee is threatened by biological agents and pesticides that can act in combination to induce synergistic effects on its physiology and lifespan. The synergistic effects of a parasite/pesticide combination have been demonstrated on workers and queens, but no studies have been performed on drones despite their essential contribution to colony sustainability by providing semen diversity and quality. The effects of the Nosema ceranae/fipronil combination on the life traits and physiology of mature drones were examined following exposure under semi-field conditions...

BACKGROUND Atrioventricular conduction delay (AVCD) impairs left ventricular (LV) filling and consequently leads to a reduction of cardiac output. We hypothesized that in patients with severely depressed LV function and coexisting intraventricular conduction disturbances (IVCD), AVCD can affect exercise performance. Therefore, we evaluated the association of AVCD and exercise capacity in patients with heart failure (HFREF) and coexisting IVCD. MATERIAL AND METHODS We included patients with stable, chronic HFREF, LVEF <35%, sinus rhythm, and QRS ≥120 ms...

Surveillance for West Nile virus (WNV) and other mosquito-borne pathogens involves costly and time-consuming collection and testing of mosquito samples. One difficulty faced by public health personnel is how to interpret mosquito data relative to human risk, thus leading to a failure to fully exploit the information from mosquito testing. The objective of our study was to use the information gained from historic West Nile virus mosquito testing to determine human risk relative to mosquito infection and to assess the usefulness of our mosquito infection forecasting models to give advance warning...
