BACKGROUND: Drowning leading to out-of-hospital cardiac arrest (OHCA) and death is a major public health concern. Submersion with duration of less than 10minutes is associated with favourable neurological outcome and nearby bystanders play a considerable role in rescue and resuscitation. Drones can provide a visual overview of an accident scene, their potential as lifesaving tools in drowning has not been evaluated. AIM: The aim of this simulation study was to evaluate the efficiency of a drone for providing earlier location of a submerged possible drowning victim in comparison with standard procedure...

The increased popularity of paravertebral block (PVB) can be attributed to its relative safety and comparable efficacy when compared with epidural analgesia. It has thus been recommended for open cholecystectomy and other less painful surgeries such as inguinal herniorraphy and appendectomy. We performed a systematic review of PVB in paediatric abdominal conditions to assess its clinical efficacy and side effects compared with other analgesic therapies.A search of Medline, Embase, and Web of Science and hand-searching references from inception date to May 2016 was done...

MOTIVATION: Identifying biologically meaningful gene expression patterns from time series gene expression data is important to understand the underlying biological mechanisms. To identify significantly perturbed gene sets between different phenotypes, analysis of time series transcriptome data requires consideration of time and sample dimensions. Thus, the analysis of such time series data seeks to search gene sets that exhibit similar or different expression patterns between two or more sample conditions, constituting the three-dimensional data, i...

BACKGROUND: More than 85% of children affected by acute lymphoblastic leukemia (ALL) are successfully treated; however relapse remains a remarkable clinical concern, with 50-60% of relapsing patients facing a fatal outcome. Management of relapsed patients includes standardized intensive risk-adapted regimens based on conventional drugs, and hematopoietic stem cells transplantation for patients with unfavourable features. Biological drugs, in particular the monoclonal antibody epratuzumab and the bi-functional recombinant single chain peptide blinatumomab, have been recently recognized as novel potential agents to be integrated in salvage ALL therapy to further improve rescue outcome...

Klaus Hackner, Joachim Pleil
Recent literature has touted the use of canine olfaction as a diagnostic tool for identifying pre-clinical disease status, especially cancer and infection from biological media samples. Studies have shown a wide range of outcomes, ranging from almost perfect discrimination, all the way to essentially random results. This disparity is not likely to be a detection issue; dogs have been shown to have extremely sensitive noses as proven by their use for tracking, bomb detection and search and rescue. However, in contrast to analytical instruments, dogs are subject to boredom, fatigue, hunger and external distractions...

BACKGROUND: Inhaled nitric oxide (iNO) is effective in term infants with hypoxic respiratory failure. The pathophysiology of respiratory failure and the potential risks of iNO differ substantially in preterm infants, necessitating specific study in this population. OBJECTIVES: To determine effects of treatment with inhaled nitric oxide (iNO) on death, bronchopulmonary dysplasia (BPD), intraventricular haemorrhage (IVH) or other serious brain injury and on adverse long-term neurodevelopmental outcomes in preterm newborn infants with hypoxic respiratory failure...

Lipoarabinomannan (LAM) and arabinogalactan (AG) are the two major mycobacterial cell wall (lipo)polysaccharides, which contain a structurally similar arabinan domain that is highly branched and assembled in a stepwise fashion by variety of arabinofuranosyltransferases (ArafT). In addition to playing an essential role in mycobacterial physiology, LAM and its biochemical precursor lipomannan possess potent immunomodulatory activities that affect the host immune response. In the search of additional mycobacterial ArafTs that participate in the synthesis of the arabinan segment of LAM, we disrupted aftB (MSMEG_6400) in Mycobacterium smegmatis...

BACKGROUND: Cortical motor neurons, also known as upper motor neurons, are large projection neurons whose axons convey signals to lower motor neurons to control the muscle movements. Degeneration of cortical motor neuron axons is implicated in several debilitating disorders, including hereditary spastic paraplegia (HSP) and amyotrophic lateral sclerosis (ALS). Since the discovery of the first HSP gene, SPAST that encodes spastin, over 70 distinct genetic loci associated with HSP have been identified...

The erythropoietin (Epo) gene is under tissue-specific inducible regulation. Because kidney is the primary EPO-producing tissue in adults, impaired EPO production in chronic kidney disorders results in serious renal anemia. The Epo gene contains a liver-specific enhancer in the 3' region, but the kidney-specific enhancer for gene expression in renal EPO-producing (REP) cells remains elusive. Here, we examined a Conserved-Upstream-element for Renal-Epo-regulation (CURE) region that spans 17.4 kb to 3.6 kb upstream of the Epo gene and harbors several phylogenetically conserved elements...

Lipid rescue is used as treatment of various poisonings despite weak scientific evidence. Some experimental studies have indicated a positive effect, but others have not. Clinical studies are lacking, wherefore a systematic review of virtually all published human case reports is presented. The case reports were searched for in PubMed and Web of Science and examined by two experts according to an assessment form grading the probability for a causal connection between lipid rescue and improved symptoms. A total of 160 cases were finally included, of which 30 had no positive effect of lipid rescue...

STUDY OBJECTIVE: Two of the most feared complications for patients undergoing thyroid surgery are pain and postoperative nausea and vomiting. Thyroidectomy is considered high risk for postoperative nausea and vomiting, and recent studies have looked at adjuncts to treat pain, limit narcotic use, "fast-track" the surgical process, and enhance recovery without compromising the patient's safety. One such perioperative medication of interest is dexmedetomidine (Dex), a centrally acting α-2 agonist that has been associated with reducing pain and postoperative opioid consumption...

INTRODUCTION: 5-Hydroxytryptamine type 3 (5-HT3) receptor antagonists are the most commonly used drugs for postoperative nausea vomiting (PONV) prophylaxis. Dexamethasone is another antiemetic with proven efficacy in reducing PONV. The aim of this study was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare the combination of dexamethasone and 5-HT3 antagonist versus a 5-HT3 antagonist alone as prophylaxis of PONV in laparoscopic surgical patients...

We investigate low-dimensional examples of cyclic pursuit in a collective, wherein each agent employs a constant bearing (CB) steering law relative to exactly one other agent. For the case of three agents in the plane, we characterize relative equilibria and pure shape equilibria of associated closed-loop dynamics. Re-scaling time yields a reduction of phase space to two dimensions and effective tools for stability analysis. Study of bifurcation of a family of collinear equilibria dependent on a single CB control parameter reveals the presence of a rich collection of trajectories that are periodic in shape and undergo precession in physical space...
