Clinical imaging modalities have reached a prominent role in medical diagnosis and patient management in the last decades. Different image methodologies as Positron Emission Tomography, Single Photon Emission Tomography, X-Rays, or Magnetic Resonance Imaging are in continuous evolution to satisfy the increasing demands of current medical diagnosis. Progress in these methodologies has been favored by the parallel development of increasingly more powerful contrast agents. These are molecules that enhance the intrinsic contrast of the images in the tissues where they accumulate, revealing noninvasively the presence of characteristic molecular targets or differential physiopathological microenvironments...

BACKGROUND: Automated systems are available in various application areas all over the world for the purpose of reducing workload and increasing safety. However, such support systems that would aid caregivers are still lacking in the medical sector. With respect to workload and safety, especially, the intensive care unit appears to be an important and challenging application field. Whereas many closed-loop subsystems for single applications already exist, no comprehensive system covering multiple therapeutic aspects and interactions is available yet...

BACKGROUND: Deficiency of lysosomal acid lipase (LAL) causes Wolman disease and cholesterol ester storage disease. With the recent introduction of enzyme replacement therapy to manage LAL deficiency comes the need for a reliable assay of LAL enzymatic activity that can be applied to dried blood spots (DBS). METHODS: We prepared and tested a library of analogs of palmitoyl 4-methylumbelifferyl esters to find a highly active and specific substrate for LAL in DBS. The LAL assay was optimized leading to both LC-MS/MS and fluorometric assay of LAL...

The French endocrinology society (SFE) and the French pediatric endocrinology society (DFSDP) have drawn up recommendations for the management of primary and secondary adrenal insufficiency in the adult and child, based on an analysis of the literature by 19 experts in 6 work-groups. A diagnosis of adrenal insufficiency should be suspected in the presence of a number of non-specific symptoms except hyperpigmentation which is observed in primary adrenal insufficiency. Diagnosis rely on plasma cortisol and ACTH measurement at 8am and/or the cortisol increase after synacthen administration...

Organic acidurias (synonym, organic acid disorders, OADs) are a heterogenous group of inherited metabolic diseases delineated with the implementation of gas chromatography/mass spectrometry in metabolic laboratories starting in the 1960s and 1970s. Biochemically, OADs are characterized by accumulation of mono-, di- and/or tricarboxylic acids ("organic acids") and corresponding coenzyme A, carnitine and/or glycine esters, some of which are considered toxic at high concentrations. Clinically, disease onset is variable, however, affected individuals may already present during the newborn period with life-threatening acute metabolic crises and acute multi-organ failure...

Eosinophilic esophagitis is an immune-mediated chronic disease of the esophagus characterized by symptoms related to esophageal dysfunction and tissue eosinophilia. In the endoscopy, the esophageal mucosa may appear normal or show exudates, rings, edema, furrows, and strictures. Its management is based on elimination diet, topical corticosteroids and/or esophageal dilation. Atresia is the most common congenital alteration of the esophagus; it requires surgical repair and poses potential complications, such as gastroesophageal reflux, strictures, and esophageal dysmotility...

Laryngeal and tracheal morbidity is a common complication of endotracheal tube (ETT)-based airway management, and manifests as local irritation, inflammation, and edema. Systemic corticosteroids are commonly administered to manage these conditions; however, their efficacy is inadequate and limited by potential severe side effects. In the present study, a steroid delivery system for local therapy was developed to generate relatively high local drug concentrations and to improve drug efficacy. ETTs were coated with electrospun poly (lactic-co-glycolic acid) (PLGA) nanofibers loaded with mometasone furoate (MF), creating a microscale thick layer...

Boric acid (H3BO3) is being used effectively nowadays in traps/baits for the management of Aedes aegypti L. and Aedes albopictus Skuse species of mosquitoes, which are the main spreading vectors worldwide for diseases like malaria, dengue and zika. Previously, we have published results on the structural, electronic and optical properties of its molecular triclinic H3BO3-2A and trigonal H3BO3-3T polymorphs within the framework of density functional theory (DFT). Due to the renewed importance of these materials, the focus of this work is on the vibrational properties of the bulk boric acid 2A and 3T polymorphs...

Salt pollution and human-accelerated weathering are shifting the chemical composition of major ions in fresh water and increasing salinization and alkalinization across North America. We propose a concept, the freshwater salinization syndrome, which links salinization and alkalinization processes. This syndrome manifests as concurrent trends in specific conductance, pH, alkalinity, and base cations. Although individual trends can vary in strength, changes in salinization and alkalinization have affected 37% and 90%, respectively, of the drainage area of the contiguous United States over the past century...

BACKGROUND: The association between tranexamic acid (TXA) and fibrinolysis shutdown is unknown. We hypothesize that TXA is associated with fibrinolysis shutdown in critically injured trauma patients. METHODS: 218 critically injured adults admitted to the intensive care unit (ICU) at an urban level 1 trauma center from 08/2011-01/2015 who had thromboelastography performed upon ICU admission were reviewed. Groups were stratified based on fibrinolysis shutdown, which was defined as LY30<0...

Empirical data on food web dynamics and predator-prey interactions underpin ecosystem models, which are increasingly used to support strategic management of marine resources. These data have traditionally derived from stomach content analysis, but new and complementary forms of ecological data are increasingly available from biochemical tracer techniques. Extensive opportunities exist to improve the empirical robustness of ecosystem models through the incorporation of biochemical tracer data and derived indices, an area that is rapidly expanding because of advances in analytical developments and sophisticated statistical techniques...

INTRODUCTION: Cholecystocolonic fistula is a rare condition and is found in roughly 1 in every 10,000. It represents 6.3% to 26.5% of all cholecystenteric fistulas (Chowbey et al., 2006; Angrisani et al., 2001; Yamashita et al., 1997). Cholecystocolonic fistula is the second most common intestinal fistula after cholecystoduodenal fistula (Costi et al., 2009). Rarity of this condition, atypical presentation, diagnostic and management challenges, makes it a unique surgical entity.

Oleaginous yeasts have been seen as a feasible alternative to produce the precursors of biodiesel due to their capacity to accumulate lipids as triacylglycerol having profiles with high content of unsaturated fatty acids. The yeast Yarrowia lipolytica is a promising microorganism that can produce lipids under nitrogen depletion conditions and excess of the carbon source. However, under these conditions, this yeast also produces citric acid (overflow metabolism) decreasing lipid productivity. This work presents two mathematical models for lipid production by Yarrowia lipolytica from glucose...
