Psychological intimate partner violence: the major predictor of posttraumatic stress disorder in abused women.

2004

Intimate partner violence (IPV) significantly impacts women mental and physical wellbeing and therefore represents a worldwide public health problem. A clear association between IPV and increased risk to develop posttraumatic stress disorder (PTSD) has been documented. However, few studies examined how different features of IPV (physical, psychological, sexual) interact with other traumatic stress experiences (physical, psychological and sexual childhood abuse and adulthood victimization by other/s than the partner) in determining PTSD. Women abused by the partner (n=75) were compared with non-abused control women (n=52). Information about sociodemographic profile and relevant personal char…

Satb2 Regulates Callosal Projection Neuron Identity in the Developing Cerebral Cortex

2008

SummarySatb2 is a DNA-binding protein that regulates chromatin organization and gene expression. In the developing brain, Satb2 is expressed in cortical neurons that extend axons across the corpus callosum. To assess the role of Satb2 in neurons, we analyzed mice in which the Satb2 locus was disrupted by insertion of a LacZ gene. In mutant mice, β-galactosidase-labeled axons are absent from the corpus callosum and instead descend along the corticospinal tract. Satb2 mutant neurons acquire expression of Ctip2, a transcription factor that is necessary and sufficient for the extension of subcortical projections by cortical neurons. Conversely, ectopic expression of Satb2 in neural stem cells m…

Membrane Protein Subunit Fractionation by Means of Inverse Pore Gradient Elution Polyacrylamide Gel Electrophoresis

1996

We report here the preparative scale isolation of the four subunits of the nicotinic acetylcholine receptor (nAChR) applying short inverse pore gradient SDS gels on an elution-PAGE apparatus. The nAChR subunits are of similar molecular weights (alpha, 50.2 kDa; beta, 53.7 kDa; gamma, 56.3 kDa; delta, 57.6 kDa) and isoelectric point (approx 5.5) and share the typical properties of amphiphatic membrane proteins that are difficult to separate by chromatographic procedures. Preparative PAGE, which has proved to be the method of choice for nAChR-subunit fractionation, however, is time-consuming and achieves only moderate resolutions yielding dilute fractions. We present here the fractionation of…

High-flow nasal therapy versus noninvasive ventilation in COPD patients with mild-to-moderate hypercapnic acute respiratory failure: study protocol f…

2019

Background Noninvasive ventilation (NIV) is indicated to treat respiratory acidosis due to exacerbation of chronic obstructive pulmonary disease (COPD). Recent nonrandomized studies also demonstrated some physiological effects of high-flow nasal therapy (HFNT) in COPD patients. We designed a prospective, unblinded, multicenter, randomized controlled trial to assess the noninferiority of HFNT compared to NIV with respect to the reduction of arterial partial pressure of carbon dioxide (PaCO2) in patients with hypercapnic acute respiratory failure with mild-to-moderate respiratory acidosis. Methods We will enroll adult patients with acute hypercapnic respiratory failure, as defined by arterial…

Diagnostic algorithm for familial chylomicronemia syndrome

2016

International audience; Background: Familial chylomicronemia syndrome (FCS) is a rare genetic disease that leads to severe hypertriglyceridemia often associated with recurrent episodes of pancreatitis. The recognition and correct diagnosis of the disease is challenging due to its rarity, and to the lack of specificity of signs and symptoms. Lipid experts, endocrinologists, gastroenterologists, pancreatologists, and general practitioners may encounter patients who potentially have FCS. Therefore, cooperation between experts and improved knowledge of FCS is essential in improving the diagnosis. Currently, a consensus on best practice for the diagnosis of FCS is lacking. Methods: Aiming to def…

Taking climate change seriously: An analysis of op-ed articles in Spanish press

2016

In this article, we study the evolution of opinion genres regarding climate change in three Spanish newspapers ( El País, El Mundo, and ABC). Analyzing the op-ed articles in these newspapers, we observe a significant change in the evolution of opinion. While denialism was very present in conservative press in 2007, 7 years later it is almost absent from El Mundo, and its presence in ABC is much lower and inactive: this shows that scientific consensus has prevailed over time and Spanish denialism has weakened, exclusively supported by political arguments by the most conservative parties.

Finding the right dose of fulvestrant in breast cancer

2012

Fulvestrant is a selective estrogen receptor downregulator, behaving as a complete antagonist. It was initially approved, at a dose of 250 mg, to treat hormone dependant breast cancer in second line setting. However, a series of pharmacological and pre-clinical studies have suggested that a higher dose of 500 mg may be more effective. The present work summarizes and discusses clinical trials that have aimed to test the benefits of administering fulvestrant at a higher dose. The data support the use of a higher, and more possibly, effective dose of the agent.

Changing paradigm in mild traumatic brain injury research

2016

Traumatic brain injury (TBI) is a major cause of death and disability among young adults. Recent data show that TBI affects about 1.7 million people annually in the United States (Faul and Coronado, 2015). After TBI, the primary injury produces almost irreparable brain damage. However, recent experimental studies have shown evidence for dynamic brain repair following TBI because endogenous progenitor cells may play regenerative roles in response to injuries (McGinn and Povlishock, 2015). In surviving patients, what plays a critical role in the clinical prognosis is the subsequent secondary injury; without effective treat- ment, cascades that include glutamatergic excitotoxicity and calcium …

Interleukins

1994

With interleukins (IL), a new class of potential drugs has been introduced into clinical research. These signal peptides are involved in the regulation of many physiological and pathophysiological processes. IL-1, -2, -3, -4, -6 and -11 have been tested in clinical trials. The growth promoting, growth inhibiting or immunomodulatory activities of interleukins represent the theoretical basis for large scale clinical testing, predominantly in malignant disease. Dose-dependent effects on numbers of peripheral blood cells and recovery from bone marrow failure have been demonstrated for IL-1, -3, -6 and -11. Phase III trials are in progress to determine their value for clinical practice. However,…
