Abstract
Helms, ER, Storey, A, Cross, MR, Browm, SR, Lenetsky, S, Ramsay, H, Dillen, C, and Zourdos, MC. RPE and velocity relationships for the back squat, bench press, and deadlift in powerlifters. J Strength Cond Res 31(2): 292–297, 2017—The purpose of this study was to compare average concentric velocity (ACV) and rating of perceived exertion (RPE) based on repetitions in reserve on the squat, bench press, and deadlift. Fifteen powerlifters (3 women and 12 men, mean age 28.4 ± 8.5 years) worked up to a one repetition maximum (1RM) on each lift. Rating of perceived exertion was recorded on all sets, and the ACV was recorded for all sets performed at 80% of estimated 1RM and higher, up to 1RM. Rating of perceived exertion at 1RM on squat, bench press, and deadlift was 9.6 ± 0.5, 9.7 ± 0.4, and 9.6 ± 0.5, respectively and was not significantly different (p > 0.05). The ACV at 1RM on squat, bench press and deadlift was 0.23 ± 0.05, 0.10 ± 0.04, and 0.14 ± 0.05 m·second−1, respectively. Squat was faster than both bench press and deadlift (p > 0.001), and deadlift was faster than bench press (p = 0.05). Very strong relationships (r = 0.88–0.91) between percentage 1RM and RPE were observed on each lift. The ACV showed strong (r = −0.79 to −0.87) and very strong (r = −0.90 to 92) inverse relationships with RPE and percentage 1RM on each lift, respectively. We conclude that RPE may be a useful tool for prescribing intensity for squat, bench press, and deadlift in powerlifters, in addition to traditional methods such as percentage of 1RM. Despite high correlations between percentage 1RM and ACV, a “velocity load profile” should be developed to prescribe intensity on an individual basis with appropriate accuracy.

Comparative effects of selected plant polyphenols, gallic acid and epigallocatechin gallate, on matrix metalloproteinases activity in multidrug resistant MCF7/DOX breast cancer cells
Authors: Nowakowska Anna , Tarasiuk Jolanta 
Published: May 2016

The aim of the study was to investigate the effect of selected polyphenols: gallic acid (GA) and epigallocatechin gallate (EGCG) on matrix metalloproteinase (MMP-2 and MMP-9) activity in multidrug resistant (MDR) human breast adenocarcinoma cells: MCF7/DOX cells and obtained recently in our laboratory MCF7/DOX500 cells by the permanent selection of MCF7/DOX cells with 500 nM doxorubicin (DOX). The activity of MMP-2 and MMP-9 and the effect of studied polyphenols on these matrix proteases were examined by gelatin zymography assays. We have found that the activity of MMP-2 and MMP-9 significantly increased in resistant MCF7/DOX and MCF7/DOX500 cells whereas they were not detected in sensitive MCF7 cells. It was also observed that GA (30, 60, 100 and 120 µM) and EGCG (5, 10 and 20 µM) caused a comparable concentration-dependent inhibition of MMP-2 and MMP-9 activity in MCF7/DOX and MCF7/DOX500 cells. Control experiments confirmed that examined compounds in these ranges of concentration did not affect the cell growth of MCF7/DOX and MCF7/DOX500 sublines (80-100% of control cell growth was observed in the presence of studied polyphenols).
Tiny Creatures: The World of Microbes by N. Davies

Published: May 2016

Davies, Nicola. Tiny Creatures: The World of Microbes. Illus. Emily Sutton. Somerville: Candlewick Press, 2014. Print.“Do you know that there are creatures so tiny that millions could fit on this ant’s antenna?” Tiny Creatures: The World of Microbes takes a close up look at the invisible world of microorganisms around us. Davies takes this potentially difficult topic and presents it in a way that is accessible to children. This picture book starts by comparing concrete ideas-- the size of a whale to the size of an ant’s antenna-- to help children visualize the size of these microbes. From there, the book goes on to explain that microbes are everywhere, even in volcanoes and our own bodies. Unlike other children’s books about germs, Davis does not focus on presenting microbes as evil monsters, with white blood cell super heroes. Instead, she frankly discusses how some microbes can make you sick, but the majority are “busy doing other things.” This is a nice movement away from the tendency in children’s books to insist that germs, generally, are the bad guys. Davis’ germs are not scary, but they are powerful.Instead of using text to show how to protect against these germs, the illustrator Emily Sutton presents pictures of children washing their hands and using mosquito netting. The watercolour artwork follows two young children exploring the world of microbes. The illustrations are bright, engaging, and effectively enhance and add to the text.Nicola Davis has published a number of children's books about nature, drawing on her expertise as a zoologist. Tiny Creatures is particularly welcome as there are so few options for books of this kind. With its accessible language and simple artwork, this book is a wonderful way to introduce children in kindergarten to grade three to the world of microbes.Highly recommended: 4 stars out of 4Reviewer: Jenny Plecash
Llama Llama Gram and Grandpa by A. Dewdney
Authors: Campbell Sandy 
Published: May 2016

Dewdney, Anna. Llama Llama Gram and Grandpa. New York, NY: Viking, 2015. PrintThis is one of a series of Llama Llama books by author/illustrator Anna Dewdney. In this volume, Llama Llama is staying away from home for the first night. The rhymed story takes him from packing at home to being left at his grandparents and unpacking. It is there that he discovers that his “fuzzy llama” is missing. At bedtime he has a meltdown where “Llama’s lips begin to quiver./ Llama starts to shake and shiver./ Llama needs Fuzzy near,/but FUZZY LLAMA ISN’T HERE!”. Grandpa Llama produces his own childhood toy and all is well. The text works well as a read-aloud for the age 3-5 intended audience. While all of the creatures in the book are llamas, they are fully anthropomorphized. The llamas drive cars, eat at a table with cutlery and grow carrots in a garden. They are essentially people who look like llamas. As a result young children will easily identify with the little llama missing his “fuzzy”. Dewdney’s artwork is excellent. The colours are bright and the characters engaging. In addition to the very human facial expressions, Dewdney uses the llama’s ears to show emotion – up and perky when happy or excited, droopy when sad or lonely.This would be a good book to read with a child who is anxious about staying away from home. It provides a starting point for talking with children about separation anxiety, though distress that Llama Llama feels is more related to his missing toy than about being away from his mother. This book is highly recommended for public libraries, elementary schools and day cares.Highly recommended: 4 stars out of 4Reviewer: Sandy CampbellSandy is a Health Sciences Librarian at the University of Alberta, who has written hundreds of book reviews across many disciplines.

Residual Effect of Poultry Litter Applications on No‐Till Cotton Lint Yield
Authors: Tewolde Haile , Sistani Karamat R. , McLaughlin Michael R. 
Published: May 2016

In no‐till cotton (Gossypium hirsutum L.) production systems, the potential residual benefits to lint yield from prior years of poultry litter applications are not well known. The objective of this study was to quantify the productivity of no‐till cotton fertilized or unfertilized with synthetic N in years subsequent to the last poultry litter application. Treatments included 3‐ or 6‐yr histories of 0, 2.2, 4.5, or 6.7 Mg ha−1 yr−1 litter; 4.5 Mg ha−1 yr−1 litter plus 67 kg ha−1 yr−1 N as urea‐ammonium nitrate solution(UAN); and 118 or 135 kg ha−1 yr−1 UAN‐N plus inorganic P and K as needed. In subsequent years, cotton was grown with residual from these treatments with or without 135 kg ha−1 yr−1 UAN‐N. Cotton produced up to 25% more lint yield in the first year from the residual of 3‐ or 6‐yr litter applications of 4.5 or 6.7 Mg ha−1 yr−1 relative to residual from synthetic fertilizers. The benefit of a 6‐yr history of 4.5 or 6.7 Mg ha−1 litter application, when followed by fertilization with 135 kg ha−1 UAN‐N, was 12% lint yield increase in the first year. The residual benefit persisted up to 5 yr but was greatest in the first year and diminished with time. The results overall show that including poultry litter as a component of the no‐till cotton fertilization system can enhance cotton production not only in the year of application but also in subsequent years after stopping litter application and resuming conventional fertilization with synthetic fertilizers.

Relative to residual from conventional fertilization practices, residual from 3‐ or 6‐yr litter applications of 4.5 or 6.7 Mg ha−1 yr−1 increased cotton lint yield by up to 25%.
Cotton planted in soil that has a history of 6 yr of 4.5 or 6.7 Mg ha−1 poultry litter application produced 12% more lint yield in the first year of returning the soil to conventional fertilization with synthetic N fertilizers.
The residual benefit of poultry litter on lint yield persisted up to 5 yr but was greatest in the first year and diminished with time.
Long‐Term Soil Changes from Forest Harvesting and Residue Management in the Northern Rocky Mountains
Authors: Jang Woongsoon , Page-Dumroese Deborah S. , Keyes Christopher R. 
Published: May 2016

Core Ideas
Long‐term (38 yr) soil changes after woody residue management were evaluated.
There were no differences in soil physical and chemical properties.
Differences in extractable cation pools may be due to different vegetation litter inputs.
Soil changes associated with forest harvesting, differing utilization levels, and post‐harvest prescribed burning were determined using an empirical study to investigate the long‐term impacts on soil physical and chemical properties at Coram Experimental Forest in northwestern Montana. In 1974, two replications of three regeneration cuttings (shelterwood, group selection, and clearcut) were installed. In addition, four residue management regimes (high utilization with no burning, medium with no burning, medium with broadcast burning, and low with broadcast burning) were implemented (∼74, 63, 65, and 54% wood removal, respectively). Thirty‐eight years after harvesting, changes were evaluated in mineral soil and forest floor physical and chemical properties (organic matter [OM], C, N, Ca, K, and Mg pools, soil bulk density, and pH) and in coarse woody debris levels. There were no differences in soil pH and bulk density across all regeneration cuttings and residue treatments, probably due to the minimal soil effects associated with the forest harvesting operations that were used (hand felling and cable yarding). Comparisons between harvest and burning and the control indicate no statistical differences in OM, C, and N contents. Minor differences in extractable cation pools were noted in several comparisons among the treatments; these may be attributed to litter inputs from the differing vegetation compositions of overstory and shrub layers rather than nutrient changes within the mineral soil itself. At this moist‐cool forest, intensive biomass utilization, with or without broadcast burning, had few long‐term impacts on soil properties of soil C, OM, and nutrients.
Long-term Arrhythmia Monitoring in Cryptogenic Stroke: Who, How, and for How Long?
Authors: Montalvo Mayra , Ali Rushna , Silver Brian , Khan Muhib 
Published: May 2016

Cryptogenic stroke and transient ischemic attack (TIA) account for approximately one-third of stroke patients [1]. Paroxys-mal atrial fibrillation (PAF) has been suggested as a major etiology of these cryptogenic strokes [2, 3]. PAF can be difficult to diagnose because it is intermittent, often brief, and asymptomatic. PAF might be more prevalent than persistent atrial fibrillation in stroke and TIA patients, especially in younger populations [4, 5]. In patients with atrial fibrillation, anticoagulation provides significant risk reduction [6]. A new generation of oral anticoagulants has been approved for non-valvular atrial fibrillation, providing a variety of therapeutic options for patients with atrial fibrillation and risk of stroke [7].Prior practice included an admission electrocardiogram (ECG) and continuous telemetry monitoring while in hospital [8]. However, this approach can lead to under-detection of brief asymptomatic events, which can occur at variable intervals, often outside of the hospital setting. Technological advancements have led to devices that can monitor cardiac rhythms outside of the hospital for longer durations resulting in higher yield of detection of atrial fibrillation events.Moreover, recent studies show that the normal monitoring time for arrhythmias may be shorter than ideal in order to detect atrial fibrillation, and increasing this interval could significantly improve detection of atrial fibrillation in these patients [9, 10].The aim of this study is to review the literature in order to define what subgroup of patients, with what methodologies, and for how long monitoring for atrial fibrillation should occur in patients presenting with cryptogenic stroke.

Published: May 2016

OBJECTIVE
Disparities in surgical access and timing to care result from a combination of complex patient, social, and institutional factors. Due to the perception of delayed presentation for overall health care services and treatment in African American patients on the part of the senior author, this study was designed to identify and quantify these differences in access and care between African American and Caucasian children with craniosynostosis. In addition, hypotheses regarding reasons for this difference are discussed.

METHODS
A retrospective study was conducted of 132 children between the ages of 0 and 17 years old who previously underwent operations for craniosynostosis at a tertiary pediatric care facility between 2010 and 2013. Patient and family characteristics, age at surgical consultation and time to surgery, and distance to primary care providers and the tertiary center were recorded and analyzed.

RESULTS
Of the 132 patients in this cohort, 88% were Caucasian and 12% were African American. The median patient age was 5 months (interquartile range [IQR] 2–8 months). African Americans had a significantly greater age at consult compared with Caucasians (median 341 days [IQR 192–584 days] vs median 137 days [IQR 62–235 days], respectively; p = 0.0012). However, after being evaluated in consultation, there was no significant difference in time to surgery between African American and Caucasian patients (median 56 days [IQR 36–98 days] vs median 64 days [IQR 43–87 days], respectively). Using regression analysis, race and type of synostoses were found to be significantly associated with a longer wait time for surgical consultation (p = 0.01 and p = 0.04, respectively, using cutoff points of ≤ 180 days vs > 180 days). Distance traveled to primary care physicians and to the tertiary care facility did not significantly differ between groups. Other factors such as parental education, insurance type, household income, and referring physician type also showed no significant difference between racial groups.

CONCLUSIONS
This study identified a correlation between race and age at consultation, but no association with time to surgery, distance, or family characteristics such as household income, parental education, insurance type, and referring physician type. This finding implies that delays in early health-seeking behaviors and subsequent referral to surgical specialists from primary care providers are the main reason for this delay among African American craniofacial patients. Future studies should focus on further detail in regards to these barriers, and educational efforts should be designed for the community and the health care personnel caring for them.
Subthalamic Stimulation Reduces Vowel Space at the Initiation of Sustained Production: Implications for Articulatory Motor Control in Parkinson’s Disease

Published: May 2016

Background: Stimulation of the subthalamic nuclei (STN) is an effective treatment for Parkinson’s disease, but complaints of speech difficulties after surgery have been difficult to quantify. Speech measures do not convincingly account for such reports. Objective: This study examined STN stimulation effects on vowel production, in order to probe whether DBS affects articulatory posturing. The objective was to compare positioning during the initiation phase with the steady prolongation phase by measuring vowel spaces for three “corner” vowels at these two time frames. Methods: Vowel space was measured over the initial 0.25 sec of sustained productions of high front (/i/), high back (/u/) and low vowels (/a/), and again during a 2 sec segment at the midpoint. Eight right-handed male subjects with bilateral STN stimulation and seven age-matched male controls were studied based on their participation in a larger study that included functional imaging. Mean values: age = 57±4.6 yrs; PD duration = 12.3±2.7 yrs; duration of DBS = 25.6±21.2 mos, and UPDRS III speech score = 1.6±0.7. STN subjects were studied off medication at their therapeutic DBS settings and again with their stimulators off, counter-balanced order. Results: Vowel space was larger in the initiation phase compared to the midpoint for both the control and the STN subjects off stimulation. With stimulation on, however, the initial vowel space was significantly reduced to the area measured at the mid-point. For the three vowels, the acoustics were differentially affected, in accordance with expected effects of front versus back position in the vocal tract. Conclusions: STN stimulation appears to constrain initial articulatory gestures for vowel production, raising the possibility that articulatory positions normally used in speech are similarly constrained.

Published: May 2016

Background: Clinical diagnosis of parkinsonian syndromes like Parkinson’s disease (PD), corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP) is hampered by overlapping symptomatology and lack of diagnostic biomarkers, and definitive diagnosis is only possible post-mortem. Objective: Since impaired protein degradation plays an important role in many neurodegenerative disorders, we hypothesized that profiles of select lysosomal network proteins in cerebrospinal fluid could be differentially expressed in these parkinsonian syndromes. Methods: Cerebrospinal fluid samples were collected from PD patients ( n = 18), clinically diagnosed 4-repeat tauopathy patients; corticobasal syndrome (CBS) ( n = 3) and PSP ( n = 8); and pathologically diagnosed PSP ( n = 8) and CBD patients ( n = 7). Each patient set was compared to its appropriate control group consisting of age and gender matched individuals. Select lysosomal network protein levels were detected via Western blotting. Factor analysis was used to test the diagnostic sensitivity, specificity and accuracy of the select lysosomal network protein expression profiles. Results: PD, CBD and PSP were markedly different in their cerebrospinal fluid lysosomal network protein profiles. Lysosomal-associated membrane proteins 1 and 2 were significantly decreased in PD; early endosomal antigen 1 was decreased and lysozyme increased in PSP; and lysosomal-associated membrane proteins 1 and 2, microtubule-associated protein 1 light chain 3 and lysozyme were increased in CBD. A panel of lysosomal-associated membrane protein 2, lysozyme and microtubule-associated protein 1 light chain discriminated between controls, PD and 4-repeat tauopathies. Conclusions: This study offers proof of concept that select lysosomal network proteins are differentially expressed in cerebrospinal fluid of Parkinson’s disease, corticobasal syndrome and progressive supranuclear palsy. Lysosomal network protein analysis could be further developed as a diagnostic fluid biomarker in parkinsonian syndromes.
INFRARED AND ULTRAVIOLET SPECTRA OF METHANE DILUTED IN SOLID NITROGEN AND IRRADIATED WITH ELECTRONS DURING DEPOSITION AT VARIOUS TEMPERATURES

Published: May 2016

ABSTRACT
We recorded the infrared and ultraviolet absorption spectra of CH4:N2 matrix samples that underwent electron bombardment during deposition in the temperature range of 10–44 K. In contrast to a previous experiment on the IR spectroscopy of electron-bombarded icy samples, methyl and azide radicals became the main products upon electron bombardment during deposition; furthermore, reduced production of nitrile species was observed for deposition at 10 and 20 K. On the other hand, for deposition above 33 K, the observed bands of the radical species (such as methyl and azide) decreased, and bands of large nitriles appeared. This observation may suggest that radical species easily diffuse and recombine to form more complex molecules in solid nitrogen at higher temperatures. Further measurements of similar samples at 10–33 K in the UV region revealed the intense band of azide radicals at 272.5 nm and weak, broad, overlapping features of methyl and azide radicals in the 225–197 nm region. For deposition at 44 K, only a broad feature centered at 219.4 nm was observed, and the possible carriers of nitrile species were proposed based on the corresponding IR spectrum and theoretical predictions of excitation energy. This band is similar to the observed absorption feature of Pluto’s surface recorded by the Hubble telescope in terms of both band position and bandwidth. Our findings therefore further support the suggestion that complex nitrile species may exist on the surface of Pluto.
