Growth is the single most important indication of the health of a child. Identification of growth disorders in all children is crucial as growth failure can be the first sign of a number of acute and chronic conditions. However, gender and racial biases have resulted in inequities in the identification, referral and treatment of children with growth disorders. In addition, short children have been impacted by a number of psychosocial issues. Heightism is prejudice or discrimination against individuals based on height, and refers to discrimination against individuals whose height is not within the normal acceptable range...

47,XXY (Klinefelter Syndrome) is associated with a spectrum of complex clinical needs that are associated with variable physical, neurocognitive and psychosocial aspects. For patients and families affected by this sex chromosome trisomy, navigation of health care services is difficult due to lack of 47,XXY awareness among many health care providers and little evidence to support endocrine and additional treatment plans. While endocrine management of androgen deficiency has been the mainstay of treatment for patients from puberty through adulthood, testosterone replacement, alone, fails to mitigate many symptoms and issues...

BACKGROUND: Peroxiredoxins (PRXs) have recently been identified as plant antioxidants. Completion of various genome sequencing projects has provided genome-wide information about PRX genes in major plant species. Two of these -- Oryza sativa (rice) and Arabidopsis -- each have 10 PRX members. Although significant progress has been made in understanding their biological roles in Arabidopsis, those functions in rice, a model crop plant, have not been well studied. RESULTS: We performed a comparative expression analysis of rice and Arabidopsis PRXs...

PURPOSE OF REVIEW: With the growing prevalence of heart failure, there is a particular need to develop new pharmacologic treatments that can improve outcomes. While there are several approved therapies for heart failure with reduced ejection fraction, there is currently no approved agent for those with preserved ejection fraction. The current review aimed to explore the utility of alternate endpoints to mortality and hospitalization. RECENT FINDINGS: There is increased interest in the use of alternative endpoints such as functional status and quality of life for heart failure drug development to focus on patients feeling better in addition to improving outcomes...

Arthur S Sherman, Joon Ha
Low frequency firing is modeled by Type 1 neurons with a SNIC, but, because of the vertical slope of the square-root-like f-I curve, low f only occurs over a narrow range of I. When an adaptive current is added, however, the f-I curve is linearized, and low f occurs robustly over a large I range. Ermentrout (Neural Comput. 10(7):1721-1729, 1998) showed that this feature of adaptation paradoxically arises from the SNIC that is responsible for the vertical slope. We show, using a simplified Hindmarsh-Rose neuron with negative feedback acting directly on the adaptation current, that whereas a SNIC contributes to linearization, in practice linearization over a large interval may require strong adaptation strength...

Diagnostic technology is rapidly evolving, and over the last decade, substantial progress has been made even for the identification of antibodies, increasingly approaching this type of diagnostic to that of automated clinical chemistry laboratory. In this review, we describe the analytical and diagnostic characteristics of chemiluminescence technology in its strength and in its applicability for a more rapid and accurate diagnosis of autoimmune diseases. The wide dynamic range, greater than that of immunoenzymatic methods, the high sensitivity and specificity of the results expressed in quantitative form, the high degree of automation and the clinical implications related to the reduction in the turnaround time, and the ability to run a large number of antibody tests (even of different isotypes), directed towards large antigenic panels in random access mode, make this technology the most advanced in the clinical laboratory, with enormous repercussions on the workflow and on the autoimmunology laboratory organisation...

The locus coeruleus (LC) is a brainstem nucleus involved in important cognitive functions. Recent developments in neuroimaging methods and scanning protocols have made it possible to visualize the human LC in vivo by utilizing a T1-weighted turbo spin echo (TSE) scan. Despite its frequent use and its application as a biomarker for tracking the progress of monoaminergic-related neurodegenerative diseases, no study to date has investigated the reproducibility and inter-observer variability of LC identification using this TSE scan sequence...

Breast cancer (BC) is the leading cause of cancer related death among women in 2014. The AURKA gene that encodes the protein called Aurora kinase A plays an important role in the progression of the cell cycle, by controlling and promoting the entry into the phase of mitosis. The single nucleotide polymorphism AURKA T91A (rs2273535) (Phe21Ile) has been identified as functional alternator of this kinase, the Ile allele is associated with the occurrence of chromosome segregation errors and tumor progression. Therefore, it is essential to know how BC risk is associated with histopathological characteristics, immunohistochemical characteristics, and genotype polymorphism in a high altitude Ecuadorian mestizo population...

To establish the influence of dissolved organic phosphorus (DOP) from different sources on the water quality of Erhai Lake in August 2014, enzymatic hydrolysis technology was used to characterize enzymatically hydrolyzable phosphorus (EHP). The results indicate that the DOP represents a significant source of the bioavailable P in the lake water and its different sources of Erhai Lake, and the bioavailability of the P pool may be underestimated by up to 55% if DOP is ignored and only the soluble-reactive phosphorus (SRP) is considered...
