Alzheimer disease<strike>s</strike> and related disorders (ADRD) remain a major public health issue. The progression of the disease is dominated by behavioral and psychological symptoms of dementia (BPSD) which are frequent and burdensome for caregivers. The aim of our survey was to study how the general practionner managed these behavioral disturbances (particularly agitation and aggressiveness) in community living patients with ADRD and support of their main caregivers. We based our study on a medical survey sent to all general practitioners (GP) practicing in four districts in Marseille near from a secure unit...

A pilot-scale (1800 kg per batch capacity) autoclave used in this study reduces municipal solid waste to a debris contaminated pulp product that is efficiently separated into its renewable organic content and non-renewable organic content fractions using a rotary trommel screen. The renewable organic content can be recovered at nearly 90% efficiency and the trommel rejects are also much easier to sort for recovery. This study provides the evaluation of autoclave operation, including mass and energy balances for the purpose of integration into organic diversion systems...

Type II methanotrophic bacteria are a promising production platform for PHA biopolymers. These bacteria are known to produce pure poly-3-hydroxybutyrate homopolymer (PHB). We isolated a strain, Methylocystis sp. WRRC1, that was capable of producing a wide range of polyhydroxybutyrate-co-hydroxyvalerate copolymers (PHB-co-HV) when co-fed methane and valerate or n-pentanol. The ratio of HB to HV monomer was directly related to the concentration of valeric acid in the PHA accumulation media. We observed increased incorporation of HV and total polymer under copper-free growth conditions...

Ultrafast ultrasonic imaging is a rapidly developing field based on the unfocused transmission of plane or diverging ultrasound waves. This recent approach to ultrasound imaging leads to a large increase in raw ultrasound data available per acquisition. Bigger synchronous ultrasound imaging datasets can be exploited in order to strongly improve the discrimination between tissue and blood motion in the field of Doppler imaging. Here we propose a spatiotemporal singular value decomposition clutter rejection of ultrasonic data acquired at ultrafast frame rate...

Chromosome instability (CIN) has been identified as a common feature of most human cancers. A number of centrosomal kinases are thought to cause CIN in cancer cells. Part of those centrosomal kinases exhibit elevated expression in a wide variety of tumours and cancer cell lines. Additionally, critical roles in many aspects of cancer cell growth, proliferation, metastasis, and drug resistance have been assigned to some of these centrosomal kinases, such as polo-like kinase 1 (PLk1) and Aurora-A kinase. Recent studies from our group and others revealed that a centrosomal kinase, Never in Mitosis (NIMA) Related Kinase 2A (NEK2A), is frequently upregulated in multiple types of human cancers...

Almond hulls contain considerable proportions (37% by dry weight) of water-soluble, fermentable sugars (sucrose, glucose, and fructose), which can be extracted for industrial purposes. The maximum optimal solids loading was determined to be 20% for sugar extraction, and the addition of 0.5% (w/v) pectinase aided in maintaining a sufficient free water volume for sugar recovery. A laboratory countercurrent extraction experiment utilizing a 1 h steep followed by three extraction (wash) stages produced a high-concentration (131 g/L fermentable sugar) syrup...

Ibrutinib (Imbruvica), a small-drug inhibitor of Bruton tyrosine kinase (BTK), is currently undergoing clinical testing in patients with multiple myeloma, yet important questions on the role of BTK in myeloma biology and treatment are outstanding. Using flow-sorted side population cells from human myeloma cell lines and multiple myeloma primary samples as surrogate for the elusive multiple myeloma stem cell, we found that elevated expression of BTK in myeloma cells leads to AKT/WNT/β-catenin-dependent upregulation of key stemness genes (OCT4, SOX2, NANOG, and MYC) and enhanced self-renewal...

Dietary soy is thought to be cancer-preventive; however, the beneficial effects of soy on established breast cancer is controversial. We recently demonstrated that dietary daidzein or combined soy isoflavones (genistein, daidzein, and glycitein) increased primary mammary tumor growth and metastasis. Cancer-promoting molecules, including eukaryotic protein synthesis initiation factors (eIF) eIF4G and eIF4E, were up-regulated in mammary tumors from mice that received dietary daidzein. Herein, we show that increased eIF expression in tumor extracts of mice after daidzein diets is associated with protein expression of mRNAs with internal ribosome entry sites (IRES) that are sensitive to eIF4E and eIF4G levels...

Hilton Franqui-Rivera, Juan C Sotomonte
Atrial fibrillation (AF) is a common cardiac arrhythmia associated with major morbidity and mortality. Atrial enlargement, remodeling, and fibrosis are key to initiation and perpetuation of AF. Therapy for AF is directed at symptom control via rate or rhythm control, as well as prevention of thromboembolic events. In the recent past multiple alternatives, including pharmacological and non-pharmacological, have emerged as possible therapies for AF. In this review, we intend to summarize the most important advances in AF therapy in recent years...

Inflammatory breast cancer (IBC) is the most lethal and least understood form of advanced breast cancer. Its lethality originates from its nature of invading the lymphatic system and absence of a palpable tumor mass. Different from other metastatic breast cancer cells, IBC cells invade by forming tumor spheroids that retain E-cadherin-based cell-cell adhesions. Herein we describe the potential of the medicinal mushroom Ganoderma lucidum (Reishi) as an attractive candidate for anti-IBC therapy. Reishi contains biological compounds that are cytotoxic against cancer cells...

Sudden cardiac death (SCD) is the most common cause of death among patients with heart failure and left ventricular systolic dysfunction. Implantable cardioverter-defibrillators (ICDs) have been shown to be the single most effective therapy for primary prevention of SCD in patients with heart failure. The superiority of this therapy was clearly established for patients with ischemic cardiomyopathy by large clinical trials, such as the Multicenter Automatic Defibrillator Implantation Trial (MADIT), Multicenter Unsustained Tachycardia Trial (MUSTT), and MADIT-II studies...

Advanced solid-state NMR techniques and wet chemical analyses were applied to investigate untreated corn stover (UCS) and its residues after dilute acid prehydrolysis (DAP) and enzymatic hydrolysis (RES) to provide evidence for the limitations to the effectiveness of enzyme hydrolysis. Advanced solid-state NMR spectral-editing techniques as well as 1H-13C two-dimensional heteronuclear correlation NMR (2D HETCOR) were employed. Our results indicated that dilute acid prehydrolysis selectively removed amorphous carbohydrates, increased aromatic CH/other protonated -C═C- and enriched alkyl CH and CH2 components...

Spontaneous coronary artery dissection (SCAD) is an extremely rare etiology of acute myocardial infarction, most commonly seen in pre-menopausal women with no risk factors for atherosclerotic coronary artery disease (CAD). We present the case of a 41-year-old woman with no history of systemic illness who presented severe, oppressive retrosternal pain with ST-segment elevations in leads I, AVL, V1 through V6 in the absence of risk factors for CAD. Emergency percutaneous coronary intervention (PCI) revealed an aneurysmatic dilatation of the left main coronary artery with complete dissection of the left anterior descending artery and the ramus branch, causing distal occlusion of the affected vessels...

Primary cardiac neoplasms are rare and left atrial myxomas represent the most common form of primary cardiac masses. We present the case of a 57-year-old woman with Diabetes Mellitus and arterial hypertension who was incidentally found to have a giant myxoma in the left atrium. She was asymptomatic but given the high risk of embolization and sudden cardiac death, surgical removal of the tumor was performed. A 6.0 x 5.0 x 4.5 cm mass was recovered, confirmed to be a benign cardiac myxoma on microscopic examination...

Non-compaction of the left ventricle is an extremely rare cardiomyopathy resulting from a defective morphogenesis of the endomyocardium. It results in an architecturally aberrant ventricular wall consisting of two layers: a compacted layer and a loose interwoven meshwork with prominent trabeculae and deep intertrabecular recesses that communicate with the left ventricular cavity. This report describes the case of a 25-year-old man with dilated cardiomyopathy, due to non-compaction of the left ventricle, presenting with a transient ischemic attack...
