The pathophysiological mechanisms underlying Myocardial Infarction with Non-Obstructive Coronary Artery Disease (MINOCA) are still under debate. Lipoprotein (a) [Lp(a)] has proinflammatory and prothrombotic actions and has been involved in the pathogenesis of atherosclerosis. However, no previous studies have linked Lp(a) levels with the probability of developing MINOCA.

The association of paracoccidioidomycosis (PCM) and tuberculosis (TB) produces an uncommon hyperinflammatory syndrome, causing multiorgan dysfunction. TB associated PCM is a rare condition, but it is fatal if not treated. Herein, we present a immunocompetent child who is admitted for fever and painful lymphadenopathy, with evidence of acid-alcohol-resistant bacillus (AARB) in cervical lymph node biopsy, antituberculous treatment was started with partial clinical improvement and is given discharge from hospital.

Pandemics have historically had a significant impact on economic inequality. However, official inequality statistics are only available at low frequency and with considerable delay, which challenges policymakers in their objective to mitigate inequality and fine-tune public policies. We show that using data from bank records it is possible to measure economic inequality at high frequency.

Rationale: Oxytocin (OT) is a neuropeptide previously related to reward, learning, memory, and stress, events associated with cocaine addiction. OT has shown anxiolytic properties in different animal models of anxiety. Moreover, previous data have demonstrated an increase in mRNA OT levels within the nucleus accumbens (NAc) following acute and chronic cocaine exposure in rats.

Historically, metals are cut up and polished to see the structure and to infer how processing influences the evolution. We can now peer into a metal during processing without destroying it using proton radiography. Understanding the link between processing and structure is important because structure profoundly affects the properties of engineering materials.

Objectives: Combined screening for chromosome abnormalities in the first trimester of pregnancy is based on maternal age, nuchal translucency (NT) and biochemical markers (PAPP-A and free β-hCG). We sought to assess the value of the variables used in the combined screening strategy taking into account maternal gravidity and foetal gender.

Study Design: Between July 1999 and December 2009, a total of 21,193 singleton pregnancies were screened for aneuploidy in the first trimester, in the Hospital Clínico San Carlos (Madrid, Spain).

The serine/threonine protein kinase paralogs ROCK1 & 2 have been implicated as essential modulators of angiogenesis; however their paralog-specific roles in endothelial function are unknown. shRNA knockdown of ROCK1 or 2 in endothelial cells resulted in a significant disruption of in vitro capillary network formation, cell polarization, and cell migration compared to cells harboring non-targeting control shRNA plasmids. Knockdowns led to alterations in cytoskeletal dynamics due to ROCK1 & 2-mediated reductions in actin isoform expression, and ROCK2-specific reduction in myosin phosphatase and cofilin phosphorylation.

Background: Rho kinase signaling plays an important role in the oncogenic process largely through its regulation of F-actin dynamics, and inhibition of this pathway results in reduction in tumor volume and metastasis across a number of tumor types. While the cytoskeletal-regulatory role of Rho kinase has been a topic of in-depth study, the mechanisms linking Rho kinase to altered gene expression are largely unknown.

Materials And Methods: Global gene expression analysis was performed on melanoma tumors treated with sham or the small molecule inhibitor Y27632.

The role of the RhoA/Rho kinase (ROCK) signaling pathway in cell survival remains a very controversial issue, with its activation being pro-apoptotic in many cell types and anti-apoptotic in others. To test if ROCK inhibition contributes to tumor cell survival or death following chemotherapy, we treated cisplatin damaged neuroblastoma cells with a pharmacological ROCK inhibitor (Y27632) or sham, and monitored cell survival, accumulation of a chemoresistant phenotype, and in vivo tumor formation. Additionally, we assayed if ROCK inhibition altered the expression of genes known to be involved in cisplatin resistance.

A CWDM network operating in reflective configuration for multiplexing remote Radio-Frequency (RF) self-referenced fiber-optic intensity sensors is analyzed and experimentally investigated. In the described approach, the use of fiber Bragg gratings as spectral selective mirrors allows to implement delay lines in the electrical domain, achieving more compact sensor-heads and easy-reconfigurable sensing points. Two measurement parameters for the sensing heads are defined and comparatively studied in terms of design parameters, linearity, sensitivity and resolution.

Intraosseous haemangioma are rare, benign tumours, and only rarely do they involve the facial bones. We present a singular case of zygomatic intraosseous haemangioma treated surgically and reconstructed with a methyl-methacrylate alloplastic prosthesis designed from a computed tomography (CT)-based 3D model. This is the first case described in the literature of a zygomatic reconstruction with a predesigned prosthesis.

It is known that changes in gene expression within the nucleus accumbens (NAc) occur during cocaine dependence development. However, identification of specific genes involved in cocaine conditioning awaits further investigation. We conducted a high throughput gene expression profile analysis of the NAc, during different stages of the environment-elicited cocaine conditioning.

Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands and is generally accepted as benign biologically. Occasionally PA may give rise to metastasis. The metastasis may develop in a PA in which a malignant transformation occurs, either arising a carcinoma in the PA (carcinoma ex-mixed tumour) or as a carcinosarcoma (so-called true malignant mixed tumour).
