Nancy R Mudrick, Carrie Jefferson Smith
This commentary considers the intersection of mandatory reporting in health settings and the public child protection system's treatment of parents with disabilities. Its impetus is the August 2015 technical assistance document issued jointly by the U.S. departments of Justice (DOJ) and Health and Human Services (HHS) that affirms the applicability of the ADA and Section 504 to child protection system (CPS) processes. The DOJ/HHS document speaks to actions of state child protection agencies and courts, without addressing the first step, mandatory reporting...

Controllable synthesis of coordination polymers (CPs) Isomers and reveal the corresponding relationship of structures and properties remains an enormous challenge. Three new supramolecular isomers have been synthesized by tuning the poly(ethylene glycol) (PEG) content in the feed. Those supramolecular isomers have the same framework formula of [Cu2I2(tppe)] and different architectures from the classical 2D stacking framework, to 3D entangled system with the co-existence of interpenetration and polycatenation, and 3D topological framework...

Group B Streptococcus (GBS), characterized by Lancefield in 1933, was not recognized as a human pathogen until the early 1970s when it emerged and replaced Escherichia coli as the most common cause of sepsis and meningitis among neonates and young infants. This article briefly gives a personnel account of the discovery of clinical syndromes of GBS distinguished by age at onset, vertical mode of transmission for early-onset disease, meningeal tropism for GBS capsular (CPS) type III strains, and protective CPS epitopes...

Background Insufficient enhancement of liver parenchyma negatively affects diagnostic accuracy of Gd-EOB-DTPA-enhanced magnetic resonance imaging (MRI). Currently, there is no reliable method for predicting insufficient enhancement during the hepatobiliary phase (HBP) in Gd-EOB-DTPA-enhanced MRI. Purpose To develop a predictor for insufficient enhancement of liver parenchyma during HBP in Gd-EOB-DTPA-enhanced MRI. Material and Methods In order to formulate a HBP enhancement test (HBP-ET), clinical factors associated with relative enhancement ratio (RER) of liver parenchyma were retrospectively determined from the datasets of 156 patients (Development group) who underwent Gd-EOB-DTPA-enhanced MRI between November 2012 and May 2015...

A procedure to estimate the activity in target tissues in patients during the therapeutic administration of (131)I radiopharmaceutical treatment for thyroid conditions (hyperthyroidism and differentiated thyroid cancer) using a gamma camera (GC) with a high energy (HE) collimator, is proposed. Planar images are acquired for lesions of different sizes r, and at different distances d, in two HE GC systems. Defining a region of interest (ROI) on the image of size r, total counts n g are measured. Sensitivity S (cps MBq(-1)) in each acquisition is estimated as the product of the geometric G and the intrinsic efficiency η 0...

We hypothesized that the neonatal rat heart would bring transplanted human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to maturity as it grows to adult size. In neonatal rat heart, engrafted hiPSC derivatives developed partially matured myofibrils after 3 months, with increasing cell size and sarcomere length. There was no difference between grafts from hiPSC-CMs or hiPSC-derived cardiac progenitors (hiPSC-CPs) at 3 months, nor was maturation influenced by infarction. Interestingly, the infarcted adult heart induced greater human cardiomyocyte hypertrophy and induction of cardiac troponin I expression than the neonatal heart...

Specific DNA-protein interactions are vital for cellular life maintenance processes, such as transcriptional regulation, chromosome maintenance, replication and DNA repair, and their monitoring gives valuable information on molecular-level organization of those processes. Here, we propose a new method of label-free electrochemical sensing of sequence specific binding between the lysozyme protein and a single stranded DNA aptamer specific for lysozyme (DNAapta) that exploits the constant current chronopotentiometric stripping (CPS) analysis at modified mercury electrodes...

Norman McOmish Dott (1897-1973) developed surgical neurology in Edinburgh, Scotland, and was a scholar of worldwide renown. One of Dott's most notable contributions to neurosurgery was his understanding of hypothalamic physiology, mostly acquired through the comprehensive study of patients with lesions involving this region of the diencephalon, particularly craniopharyngiomas (CPs). Recognition of symptoms caused by hypothalamic disturbances allowed him to predict the accurate anatomical relationships between CPs and the hypothalamus, despite the rudimentary radiological methods available during the 1930s...

Chlorinated paraffins (CPs) are used as flame retardants, plasticizers, and metalworking fluids, which have varying contents of toxic short-chain chlorinated paraffins (SCCPs). Based on the study of several relevant production and consumption sectors, this paper classifies the consumption of CPs among sectors and provides an emission inventory and the provincial emission distribution of SCCPs in China in 2010-2014 based on the consumption patterns and emission factors of each sector. The total emissions of SCCPs in China in 2014 were 3083...

Gold Nanomaterials (GNMs) interact with fluorophores via electromagnetic coupling under excitation. In this particular work we carried out (to the best of our knowledge for the first time) a comprehensive study of systematic quenching of a blue emitter 2-Anthracene Sulfonate (2-AS) in the presence of gold nanoparticles of different size and shape. We synthesized gold nanomaterials of four different dimensions [nanoparticle (0D), nanorod (1D), nanotriangle (2D) and nanobipyramids (3D)] and realized the underlying effect on the emitting dipole in terms of steady and time resolved fluorescence...
