REVIEW
Jean-Louis Vincent, David Grimaldi
Despite decades of sepsis research, no specific therapies for sepsis have emerged and current management still relies on source control, antibiotics, and organ support. With improved understanding of sepsis pathophysiology and the development of new techniques to enable better characterization of patients with sepsis, clinical trials are beginning to better target new interventions at those patients most likely to respond. This article discusses advances in sepsis therapeutics designed to improve endothelial cell function, purify the blood to help restore immune homeostasis, and provide immunostimulation for patients with immune exhaustion...

BACKGROUND: Mycolactone is a macrolide produced by the skin pathogen Mycobacterium ulcerans, with cytotoxic, analgesic and immunomodulatory properties. The latter were recently shown to result from mycolactone blocking the Sec61-dependent production of pro-inflammatory mediators by immune cells. Here we investigated whether mycolactone similarly affects the inflammatory responses of the nervous cell subsets involved in pain perception, transmission and maintenance. We also investigated the effects of mycolactone on the neuroinflammation that is associated with chronic pain in vivo...

Background and Objectives: From year 2003 we treated positively 251 patients with Traumatic Spinal Cord Injuries (TSCI), using Non-Surgical Laser Therapy (NSLT). In order to increase muscle strength, we have also started using a physical therapy practice called Grimaldi's Muscle Shortening Manoeuvre (GMSM)The goal of our study is to obtain objective data suggesting the real effectiveness of the association of these two treatments. Study Design and Methods: In 2015, 10 patients with incomplete TSCI were enrolled...

Endocrine-disrupting chemicals (EDCs) represent a broad class of exogenous substances that cause adverse effects in the endocrine system mainly by interacting with nuclear hormone receptors (NRs). Humans are generally exposed to low doses of pollutants, and current researches aim at deciphering the mechanisms accounting for the health impact of EDCs at environmental concentrations. Our correlative analysis of structural, interaction and cell-based data has revealed a variety of, sometimes unexpected, binding modes, reflecting a wide range of EDC affinities and specificities...

Nontypeable Haemophilus influenzae (NTHi) are Gram-negative pathogens that contribute to a variety of diseases, including acute otitis media and chronic obstructive pulmonary disease. As NTHi have an absolute requirement for heme during aerobic growth, these bacteria have to scavenge heme from their human hosts. These heme sources can range from free heme to heme bound to proteins, such as hemoglobin. To test the impact of heme structural factors on heme acquisition by NTHi, we prepared a series of heme sources that systematically vary in heme exposure and covalent binding of heme to peptide/protein and tested the ability of NTHi to use these sources to support growth...

Avik P Chatterjee, Claudio Grimaldi
A lattice model for continuum percolation by cylindrical rods is generalized to account for inhomogeneities in the volume fraction that are indicative of particle clustering or aggregation. The percolation threshold is evaluated from a formalism that uses two different categories of occupied sites (denoting particles) with different occupation probabilities that represent large and small local volume fractions. Our modeling framework enables independent variations in (i) the strength of the correlation that adjacent particles experience high (or low) effective volume fractions, (ii) the disparity between the macroscopically averaged volume fraction and (say) the volume fraction characterizing the regions with high effective particle concentrations, and (iii) the overall proportion of particles that are located in regions with either high or low volume fraction...

BACKGROUND: Protein kinases have been shown to be key drug targets, especially in the area of oncology. It is of interest to explore the possibilities of protein kinases as a potential target class in Plasmodium spp., the causative agents of malaria. However, protein kinase biology in malaria is still being investigated. Therefore, rather than assaying against individual protein kinases, a library of 4731 compounds with protein kinase inhibitor-like scaffolds was screened against the causative parasite, Plasmodium falciparum...

Introduction. Diagnosis of invasive aspergillosis is challenging and the gold standard for definite diagnosis remains histopathological tissue examination. However, invasive procedures such as lung biopsy are often not feasible in critically ill patients. The detection of fungal cell wall components like Aspergillus galactomannan in broncho-alveolar lavage remains a key component of the diagnostic procedure. False-positive of the Aspergillus galactomannan assay is not frequent. Case presentation. We report a case of positive galactomannan in broncho-alveolar lavage fluid after enteral nutrition aspiration without signs of invasive aspergillosis...

: The authors read the article "The importance of registries in the postmarketing surveillance of surgical meshes" by Kockerling et al, and they completely agree on the role of a clinical follow-up of surgical meshes even if they suggest that a surveillance longer than one year is advisable, particularly in IPOM repair, to collect not only late complications but also more serious adverse events. This seems be the only way to properly assess the safety of the mesh.

The health care reforms of last years have deeply affected the National Health System, resulting in the need for a change in organizational processes and a more efficient and dynamic change management. An effective change management is not possible without a deep involvement (engagement) of professionals, which is itself a key requisite for motivation. This study aims to examine the main instruments of engagement management, as a tool of change according to a modern reorganization approach. We examine the results of this process in the Mental Health Department of the Local Health Company Naples 3 South in recent years, starting with the analysis of its main weaknesses...

Context: Daily PTH(1-34) administrations can reduce the required total daily dose of calcium/calcitriol and restore normocalcemia in refractory hypoparathyroidism. However, most of the PTH(1-34) trials were conducted on small cohorts including subjects with hypoparathyroidism of various etiologies and quality of life(QOL) was not investigated. Objective: To investigate the effects of 24 month PTH(1-34) treatment in a homogeneous cohort of adult subjects with postoperative hypoparathyroidism and to evaluate quality of life(QOL) changes...

Median and Ulnar nerve palsy is a devastating condition that compromise hand function. A procedure of tendon transfer may be helpful to restore the movements by linking palsy muscles to other muscles able to contract. Scientific discoveries and technological innovations have profoundly changed this kind of surgery; studies on sarcomeres, for example, changed the concept of tensioning. To date we know that muscle strength and its contraction capacity depends on many factors (not only tensioning) such as sarcomeres length, cellular cytoskeleton and extracellular matrix composition: all of these factors interact together and in a ways not still fully understood, determining the complex concept of "movement...

BACKGROUNDS: Perioperative fluid-therapy is a still a debated issue. In hepatic surgery, volume load must be strictly monitored to assure both a safe hemodynamics and low central venous pressure (CVP) to limit the backflow bleeding. Retrospectively, we compared intraoperative fluid management before and after the adoption of a semi-invasive hemodynamic monitoring. METHODS: We compared patients submitted to liver resection monitored by FloTrac/VigileoTM (group A) vs...

Poly-ADP-ribose-polymerases (PARPs) 1 and 2 are nuclear enzymes that catalyze the poly-ADP-ribosylation of nuclear proteins transferring poly-ADP-ribose (PAR) polymers to specific residues. PARPs and PAR intervene in diverse functions, including DNA repair in the nucleus and stress granule assembly in the cytoplasm. Stress granules contribute to the regulation of translation by clustering and stabilizing mRNAs as well as several cytosolic PARPs and signaling proteins to modulate cell metabolism and survival...

Nowadays, with the increase of computational analysis in sciences such as biology and neuroscience, the computational aspect is one of the most challenging. The purpose of this work is the achieve the possibility to apply spatio-temporal networks inference techniques on brain to perform network analysis. One of the problems of spatio-temporal network applications is the computational time, and it becomes impractical to keep developing studies when it takes a long time to analyze and compute the results. We present a GPU-based system used to speed up the computation of spatio-temporal networks applied to different brain data; thanks to the architecture of these devices we are able to obtain an average increase in the performances of ~ 35× on a single GPU and ~ 78× on multi GPU with the respect of CPU execution...

This work sought to obtain and evaluate zero trans-fat reduced in saturated fatty acids, with higher content of unsaturated fatty acids. Palm oil (PO) was used as the reference of zero trans lipid base. Different amounts of linseed oil (LO) were added to PO, obtaining the following blends: 100:0; 80:20; 60:40; 40:60; 20:80 and 0:100 of PO:LO (w/w%), respectively. These blends were added to fully hydrogenated soybean oil (FHSO) as the crystallization modifying agent, and to sorbitan monostearate (SMS) as the structuring element, both at a proportion of 3% to build the structured fractions...
