#1
Juliana Lopez Marulanda, Olivier Adam, Fabienne Delfour
Bottlenose dolphins are highly social cetaceans with an extensive sound production including clicks, burst-pulsed sounds, and whistles. Some whistles, known as signature whistles, are individually specific. These acoustic signatures are commonly described as being emitted in contexts of stress during forced isolation and as group cohesion calls. Interactions between humans and captive dolphins is largely based on positive reinforcement conditioning within several training/feeding sessions per day. Vocal behavior of dolphins during these interactions might vary...

The efficacy of treatment for intravenous elemental mercury intoxication has not been fully studied with regard to clinical outcomes, and treatment recommendations vary. We treated a 41-year-old man with a history of drug abuse and depression who attempted suicide using 1 mL (13.53 g) metallic Hg i.v. He was admitted to the hospital two months later for dyspnoea and thoracic pain and was diagnosed with pneumonia. Hg deposits were seen in the lungs and extra-pulmonary organs. His blood level (372 μg/L) exceeded the population level of 5 μg/L by more than 70-fold...

: Approximately a quarter of the world's population at some point in life is at risk of developing shingles (Herpes Zoster). In 10-20% of cases the first branch of the trigeminal nerve gets involved (Herpes Zoster Ophthalmicus, HZO). Ophthalmic complications of HZO are able to cause a significant reduction in visual function. AIM: To study and summarize clinical features of HZO (including the rate of complications and their nature) and to determine the relationship between clinical and laboratory data from these patients...

Microorganisms produce a wide spectrum of (phospho)lipases that are secreted in order to make external substrates available for the organism. Alternatively, other (phospho)lipases may be physically associated with the producing organism causing a turnover of intrinsic lipids and frequently giving rise to a remodeling of the cellular membranes. Although potential (phospho)lipases can be predicted with a number of algorithms when the gene/protein sequence is available, experimental proof of the enzyme activities, substrate specificities, and potential physiological functions has frequently not been obtained...

Carboxylic acids are organic acids containing one or more terminal carboxyl (COOH) functional groups. Short chain carboxylic acids (SCCAs; carboxylic acids containing three to six carbons), such as malate and citrate, are critical to the proper functioning of many biological systems, where they function in cellular respiration and can serve as indicators of cell health. In foods, organic acid content can have significant impact on taste, with increased SCCA levels resulting in a sour or "acid" taste. Because of this, methods for the rapid analysis of organic acid levels are of particular interest to the food and beverage industries...

Traditional measures of intracellular antimicrobial activity and eukaryotic cell cytotoxicity rely on endpoint assays. Such endpoint assays require several additional experimental steps prior to readout, such as cell lysis, colony forming unit determination, or reagent addition. When performing thousands of assays, for example, during high-throughput screening, the downstream effort required for these types of assays is considerable. Therefore, to facilitate high-throughput antimicrobial discovery, we developed a real-time assay to simultaneously identify inhibitors of intracellular bacterial growth and assess eukaryotic cell cytotoxicity...

This detailed protocol describes the new Spin Saturation Transfer Difference Nuclear Magnetic Resonance protocol (SSTD NMR), recently developed in our group to study processes of mutual-site chemical exchange that are difficult to analyze by traditional methods. As the name suggests, this method combines the Spin Saturation Transfer method used for small molecules, with the Saturation Transfer Difference (STD) NMR method employed for the study of protein-ligand interactions, by measuring transient spin saturation transfer along increasing saturation times (build-up curves) in small organic and organometallic molecules undergoing chemical exchange...

Foodborne infections in the US caused by Vibrio species have shown an upward trend. In the genus Vibrio, V. parahaemolyticus is responsible for the majority of Vibrio-associated infections. Thus, accurate differentiation among Vibrio spp. and detection of V. parahaemolyticus is critically important to ensure the safety of our food supply. Although molecular techniques are increasingly common, culture-depending methods are still routinely done and they are considered standard methods in certain circumstances...

The FDA approved a multicenter, double-blind, Phase III, pivotal trial testing deep brain stimulation in 280 people with very early stage Parkinson's disease (PD; IDE#G050016). In partnership with The Michael J. Fox Foundation for Parkinson's Research, we conducted a survey to investigate motivating factors, barriers, and gender differences for participation in a trial testing DBS in early PD. The majority of survey respondents (72%) indicated they would consider learning more about participating. Men and women with early PD are likely to consider enrolling in trials of invasive therapies that may slow symptom progression and help future patients...

Alzheimer' disease (AD) is the most common form of dementia affecting up to 6% of the population over the age of 65. In order to discover differentially expressed proteins that might serve as potential biomarkers, the serums from AD patients and healthy controls were compared and analyzed using the proteomics approach of isobaric tagging for relative and absolute quantitation (iTRAQ). For the first time, AD biomarkers in serums are investigated in the Han Chinese population using iTRAQ labeled proteomics strategy...

Observational and interventional studies indicate a direct link between the patients' physical activity and the extent of behavioral and psychological symptoms of dementia (BPSD). At present, there are no evidence-based recommendations for physical exercise in the acute dementia care settings. Hence, this systematic review investigates the effects of short-term exercise trials on BPSD. Trials with a length up to three months investigating the effects of structured exercise interventions on BPSD in acute dementia care settings were included...

BACKGROUND & AIMS: Magnetic-resonance-imaging (MRI) techniques and ultrasound-based transient elastography (TE) can be used in noninvasive diagnosis of fibrosis and steatosis in patients with nonalcoholic fatty liver disease (NAFLD). We performed a prospective study to compare the performance of magnetic resonance elastography (MRE) vs TE for in diagnosis of fibrosis, and MRI-based proton density fat fraction (MRI-PDFF) analysis vs TE-based controlled attenuation parameter (CAP) for diagnosis of steatosis in patients undergoing biopsy to assess NAFLD...

OBJECTIVE Surgery has been considered the standard treatment for spinal osteoid osteomas that are refractory to analgesic agents. Radiofrequency ablation (RFA) is a less invasive technique with established efficiency for the treatment of peripheral osteoid osteomas. The main objectives of this study are to evaluate the safety of RFA based on the results of a previous experimental study in rats conducted in the authors' laboratory and to identify its short- and long-term efficiency in the treatment of spinal osteoid osteomas...

Obesity is a global health issue. Despite well-intentioned efforts by public institutions, traditional health promotion techniques often lead to offending those most in need of weight loss. For example, when Bryn Mawr College targeted overweight students to offer a free fitness and nutrition program, it was met with accusations of fat-shaming, indicating that weight-centric messages operate in a more complex sociocultural system than many public health concerns. To better understand reactions to weight-centric health messages, college-aged women evaluated the Bryn Mawr College e-mail...

A novel carbon structure, highly branched homogeneous-N-doped graphitic (BNG) tubular foam, is designed via a novel N, N-dimethylformamide (DMF)-mediated chemical vapor deposition method. More structural defects are found at the branched portions as compared with the flat tube domains providing abundant active sites and spacious reservoirs for Li(+) storage. An individual BNG branch nanobattery is constructed and tested using in situ transmission electron microscopy and the lithiation process is directly visualized in real time...

There is relatively little literature on adjuvant radiotherapy after radical nephroureterectomy with bladder cuff excision (RNU) for patients with upper tract urothelial carcinoma (UTUC). This study was designed to determine the efficacy of adjuvant radiotherapy for patients with pT3N0M0 UTUC. We retrospectively reviewed 198 patients treated with RNU between December 2001 and January 2015. Postoperative radiotherapy was administered in 40 (20.2%) of patients. Patients who received radiotherapy were younger than those that did not (65...

Studies show that radiotherapy of a primary tumor in combination with immunoadjuvants (IA) can result in increased survival or immune-mediated regression of metastasis outside the radiation field, a phenomenon known as abscopal effect. However, toxicities due to repeated systematic administration of IA have been shown to be a major obstacle in clinical trials. To minimize the toxicities and prime a more potent immune response, Ngwa et al have proposed that inert radiotherapy biomaterials such as fiducials could be upgraded to multifunctional ones loaded with IA for in situ delivery directly into the tumor sub-volume at no additional inconvenience to patients...

The recent outbreak of Ebola virus disease in West Africa has led to more than 11,000 deaths, with a peak in mortality from August through December of 2014. A meeting convened by the World Health Organization (WHO) in September 2014, concluded that an urgent unmet need exists for efficacy and safety testing of the Ebola virus vaccine candidates and that clinical trials should be expedited. These vaccines could be used both in an outbreak setting and to provide long-term protection in populations at risk of sporadic outbreaks...

Sudden cardiac death (SCD) is a tragic event affecting millions of individuals worldwide. Although several studies have investigated the epidemiology of SCD, these studies may have been affected by reporting and referral biases, which are reflected in the very different incidence rates and causes of deaths that have previously been reported. Among SCD victims aged < 36 years, inherited cardiac diseases are well known to play an important role. However, the extent to which inherited cardiac diseases also play a role in SCD victims aged < 50 years has not been completely described...

INTRODUCTION: Refractory coeliac disease (RCD) is a rare and severe malabsorptive disease. The condition has two subtypes: RCDI and RCDII. Different treatments have been tested: and because RCD has a poor prognosis due to progress to enteropathy-associated T-cell lymphoma, the aim was to review the epidemiologic aspects and the therapeutic options for RCD. METHODS: A systematic literature search was performed in 18 databases, and 122 records were identified. Incidence, prevalence, treatment methods and their efficacy were evaluated...
