OBJECTIVE: Pediatric code blue activations are infrequent events with a high mortality rate despite the best effort of code teams. The best method for training these code teams is debatable; however, it is clear that training is needed to assure adherence to American Heart Association (AHA) Resuscitation Guidelines and to prevent the decay that invariably occurs after Pediatric Advanced Life Support training. The objectives of this project were to train a multidisciplinary, multidepartmental code team and to measure this team's adherence to AHA guidelines during code simulation...

PURPOSE: Pediatric transport teams rely on communication to report patient data to medical command officers, who create care plans and determine disposition. Common destinations are the emergency department (ED), pediatric intensive care unit (PICU), or regular inpatient care area (RIPCA). Telephone report does not result in complete understanding of the patient's condition. Further workup in the ED is often required. Telemedicine allows the patient to be directly seen; parents to be interviewed; and laboratory studies, radiographs, and vital signs to be reviewed...

Maxillary sinus floor elevation has been documented as a safe and predictable procedure for gaining vertical bone height in the atrophic posterior maxillae. Conversely, there is a lack of basic research on the characteristics of the union between the sinus membrane (SM) and the bone. Clinical implications of an impaired union in healthy or pathologic membranes remain unknown. The objective of this study was to present a comprehensive histologic and morphologic description of the sinus membrane-lateral bone wall complex...

Adaptive responses to thermal stress in poikilotherms plays an important role in determining competitive ability and species distributions. Amino acid substitutions that affect protein stability and modify the thermal optima of orthologous proteins may be particularly important in this context. Here, we examine a set of 2,770 protein-coding genes to determine if proteins in a highly invasive heat tolerant blue mussel (Mytilus galloprovincialis) contain signals of adaptive increases in protein stability relative to orthologs in a more cold-tolerant M...

Cell death mechanism triggered by aluminium (Al) ion was investigated at root apex of tobacco (cultivar Bright Yellow) and in cultured tobacco cell line BY-2 derived from Bright Yellow, focusing on VPE genes (NtVPE1a, NtVPE1b, NtVPE2, NtVPE3). Cell death was detected as a loss of integrity of the plasma membrane by vital staining with fluorescein diacetate (in root apex) and Evans blue (in BY-2), respectively. At root apex, the upregulation of gene expression of VPE1a and VPE1b was observed significantly after 9h of Al exposure in parallel with an enhancement of cell death, while the upregulation of VPE2 and VPE3 were observed later...

BACKGROUND: Welders are exposed to many known and suspected carcinogens. An excess lung cancer risk among welders is well established, but whether this is attributable to welding fumes is unclear. Excess risks of other cancers have been suggested, but not established. We investigated welding cancer risks in the population-based Canadian Census Health and Environmental Cohort. METHODS: Among 1.1 million male workers, 12,845 welders were identified using Standard Occupational Classification codes and followed through retrospective linkage of 1991 Canadian Long Form Census and Canadian Cancer Registry (1992-2010) records...

In this report, we describe incremental changes, during a 2-year period at a single center with the administration of maintenance infliximab infusions. Given practice-driven changes consisting of 1-hour infusions and omission of premedications, we aimed to investigate if these changes contributed to severe infusion reactions. We reviewed approximately 900 infliximab infusions in a pediatric ambulatory infusion center from January 1, 2014, to December 31, 2015, for severe adverse reactions requiring either rescue epinephrine or a code blue or "rapid response" activation...

BACKGROUND/AIMS: Osteoarthritis (OA) is a degenerative joint disease characterized by articular cartilage degradation. The degradation of the extracellular matrix (ECM) of chondrocyte is closely associated with the destruction of joints in OA patients. lncRNAs are non-coding segments of RNA that possess important regulatory functions at the cellular level and in a variety of pathophysiological processes. The present study was conducted to investigate whether lncRNA-CIR regulated the expression of MMP13 as a sponge of miR-27 in OA...

Nina Gerhards, Shu-Ming Li
The blue cheese-making fungus Penicillium roqueforti produces isofumigaclavine A as the main ergot alkaloid. Recently, genome mining revealed the presence of two DNA loci bearing the genetic potential for its biosynthesis. In this study, a short-chain dehydrogenase/reductase (SDR) from one of the loci was proved to be responsible for the conversion of chanoclavine-I to its aldehyde. Furthermore, a putative gene coding for an enzyme with high homology to Old Yellow Enzymes (OYEs) involved in the ergot alkaloid biosynthesis was found outside the two clusters...

BACKGROUND: Long non-coding RNA MALAT1 (Metastasis-associated lung Adenocarcinoma transcript-1) has been demonstrated to play a critical role in the regulation of cancer progression and metastasis. However, little is known about MALAT1 in nasopharyngeal carcinoma (NPC) pathogenesis and progression. METHODS: Quantitative real-time PCR (qRT-PCR) was conducted to measure the expression of MALAT1, miR-124 and Capn4 mRNA in NPC cell lines. The protein level of Capn4 was examined by western blot analysis...

The coding sequence of a peroxidase from the secretome of Pleurotus sapidus was cloned from a cDNA library. Bioinformatic analyses revealed an open reading frame of 1551 bp corresponding to a primary translation product of 516 amino acids. The DyP-type peroxidase was heterologously produced in Trichoderma reesei with an activity of 55,000 U L(-1). The enzyme was purified from the culture supernatant, biochemically characterized and the kinetic parameters were determined. The enzyme has an N-terminal signal peptide composed of 62 amino acids...

Fluorescent polymer nanoparticles for long-term labeling and tracking of living cells with any desired color code are developed. They are built from biodegradable poly(lactic-co-glycolic acid) polymer loaded with cyanine dyes (DiO, DiI, and DiD) with the help of bulky fluorinated counterions, which minimize aggregation-caused quenching. At the single particle level, these particles are ≈20-fold brighter than quantum dots of similar color. Due to their identical 40 nm size and surface properties, these nanoparticles are endocytosed equally well by living cells...

We present a portable multi-contrast microscope capable of producing bright-field, dark-field, and differential phase contrast images of thin biological specimens on a smartphone platform. The microscopy method is based on an imaging scheme termed "color-coded light-emitting-diode (LED) microscopy (cLEDscope)," in which a specimen is illuminated with a color-coded LED array and light transmitted through the specimen is recorded by a color image sensor. Decomposition of the image into red, green, and blue colors and subsequent computation enable multi-contrast imaging in a single shot...

It is generally known that in the skin sympathetic fibers innervate various dermal structures, including sweat glands, blood vessels, arrectores pilorum muscles and hair follicles. However, there is a lack of data about the distribution and chemical phenotyping of the sympathetic chain ganglia (SChG) neurons projecting to the skin of the pig, a model that is physiologically and anatomically very representative for humans. Thus, the present study was designed to establish the origin of the sympathetic fibers supplying the porcine skin of the hind leg, and the pattern(s) of putative co-incidence of dopamine-β-hydroxylase (DβH) with pituitary adenylate cyclase-activating polypeptide (PACAP), somatostatin (SOM), neuronal nitric oxide synthase, substance P, vasoactive intestinal peptide, neuropeptide Y (NPY), leu5-enkephalin and galanin (GAL) using combined retrograde tracing and double-labeling immunohistochemistry...

Spinocerebellar degeneration, termed as ataxia is a neurological disorder of central nervous system, characterized by limb in-coordination and a progressive gait. The patient also demonstrates specific symptoms of muscle weakness, slurring of speech, and decreased vibration senses. Expansion of polyglutamine trinucleotide (CAG) within ATXN2 gene with 35 or more repeats, results in spinocerebellar ataxia type-2. Protein ataxin-2 coded by ATXN2 gene has been reported to have a crucial role in translation of the genetic information through sequestering the histone acetyl transferases (HAT) resulting in a state of hypo-acetylation...

Metagenomic techniques have been successfully used to monitor antibiotic resistance genes in environmental, animal and human ecosystems. However, despite the claim that the food chain plays a key role in the spread of antibiotic resistance, metagenomic analysis has scarcely been used to investigate food systems. The present work reports a functional metagenomic analysis of the prevalence and evolution of tetracycline resistance determinants in a raw-milk, blue-veined cheese during manufacturing and ripening...
