Thermal Acclimatization in Overwintering Tadpoles of the Green Frog, Lithobates clamitans (Latreille, 1801)
Authors: Gray Kathryn T. , Escobar Astrid M. , Schaeffer Paul J. , Mineo Patrick M. , Berner Nancy J.
Published: May 2016

Seasonal acclimatization permits organisms to maintain function in the face of environmental change. Tadpoles of the green frog (Lithobates clamitans) overwinter as tadpoles in much of their range. Because they are active in winter, we hypothesized that green frog tadpoles would display acclimatization of metabolic and locomotor function. We collected tadpoles in Sewanee, Tennessee (35.2°N) in winter and summer. Tadpoles collected during each season were tested at both winter (8°C) and summer (26°C) temperatures. Winter tadpoles were able to maintain swimming performance at both temperatures, whereas swimming performance decreased at cold temperatures in summer tadpoles. There was no evidence for seasonal acclimatization of whole‐animal metabolic rate. Although whole‐animal metabolic acclimatization was not observed, the activities of cytochrome c oxidase, citrate synthase, and lactate dehydrogenase measured in skeletal muscle homogenates showed higher activity in winter‐acclimatized tadpoles indicating compensation for temperature. Further, the composition of muscle membranes of winter tadpoles had less saturated and more monounsaturated fatty acids and a higher ω‐3 balance, unsaturation index, and peroxidation index than summer tadpoles. These data indicate that reversible phenotypic plasticity of thermal physiology occurs in larval green frog tadpoles. They appear to compensate for colder temperatures to maintain burst‐swimming velocity and the ability to escape predators without the cost of maintaining a constant, higher standard metabolic rate in the winter.
Transient expression of the diseased phenotype of osteoarthritic chondrocytes in engineered cartilage
Authors: Silverstein Amy M. , Stoker Aaron M. , Ateshian Gerard A. , Bulinski J. Chloe , Cook James L. , Hung Clark T.
Published: May 2016

Due to the degradation of osteoarthritic (OA) cartilage in post‐traumatic OA (PTOA), these tissues are challenging to study and manipulate in vitro. In this study, chondrocytes isolated from either PTOA (meniscal‐release (MR) model) or normal (contralateral limb) cartilage of canine knee joints were used to form micropellets to assess the maintenance of the OA chondrocyte phenotype in vitro. Media samples from the micropellet cultures were used to measure matrix metalloproteinase (MMP), chemokine, and cytokine concentrations. Significant differences in matrix synthesis were observed as a function of disease with OA chondrocytes generally synthesizing more extracellular matrix with increasing time in culture. No donor dependent differences were detected. Luminex multiplex analysis of pellet culture media showed disease and time‐dependent differences in interleukin (IL)‐8, keratinocyte chemoattractant (KC)‐like protein, MMP‐1, MMP‐2, and MMP‐3, which are differentially expressed in OA. This memory of their diseased phenotype persists for the first 2 weeks of culture. These results demonstrate the potential to use chondrocytes from an animal model of OA to study phenotype alterations during the progression and treatment of OA. © 2016 Orthopaedic Research Society.

The Estimation of Phytoplankton Production in the Ocean from Chlorophyll and Light Data1
Authors: RYTHER J. H. , YENTSCH C. S.
Published: May 2016

The relationship was determined between photosynthetic rate at light saturation and chlorophyll content in natural populations and cultures of marine phytoplankton. A mean value of 3.7 g C assimilated/hour/g chlorophyll was obtained from the experimental results and from data present in the literature.

A method is described by means of which organic production beneath a unit of sea surface may be estimated from the chlorophyll content of the water, the total daily solar radiation reaching the sea surface, and the extinction coefficient of visible light in the water column. Production values calculated by this method are compared with values obtained by in situ productivity measurements.

Synthesis, crystal structure and dielectric properties of C6H18N2SbCl5
Authors: Kharrat Houda , Elfaleh Nizar , Kamoun Slaheddine
Published: May 2016

The result of the X‐ray diffraction, differential scanning calorimetry and dielectric studies on a new crystal material C6H18N2SbCl5 is presented. The new organic–inorganic compound has been synthesized and characterized by the X‐ray diffraction method at 296(2) K. It crystallizes in the monoclinic P21/n space group. The cell dimensions are: a = 5.8617(1) Å, b = 15.7069(2) Å, c = 16.6693(2) Å, β = 97.627(1)° and Z = 4. The crystal structure consists of a discrete ionic layer of (C6H18N2)2+ cations and [SbCl5]2− anions linked via simple and bifurcated N―H · · · Cl hydrogen bonds. DSC analysis shows that this compound undergoes a phase transition at about (384 ± 2) K. AC and DC conductivities, complex dielectric permittivity ε*(ω) and complex electrical modulus M*(ω) were respectively studied as temperature and frequency functions. The combined data support each other and confirm the existence of a structural phase transition at about 384 K. Moreover, the temperature dependence of the DC conductivity and relaxation frequency followed the Arrhenius relation. The frequency dependence of the real part of the AC conductivity in both phases follows the Jonscher's universal dynamic law:
. The behavior of s(T) with temperature suggests that the hopping over barrier model (CBH) and the small polaron tunneling mechanism (SPTM) prevail in phases I and II, respectively. Copyright © 2016 John Wiley & Sons, Ltd.
Post‐cracking shear strength and deformability of HSS‐UHPFRC beams
Authors: Qi Jia‐Nan , Ma Zhongguo John , Wang Jing‐Quan , Liu Tong‐Xu
Published: May 2016

Eleven T‐beams, reinforced with high strength steel, were tested to failure to investigate the effect of shear span to depth ratio, fibre ratio, fibre type, concrete strength and stirrup ratio on the shear behaviour, especially post‐cracking shear strength and deformability, of ultra‐high performance fibre reinforced concrete (UHPFRC) beams. Test results indicated that fibres were efficient not only in enhancing the post‐cracking shear strength, but also in improving the post‐cracking deformability of UHPFRC beams. In addition, fibres could bridge the cracks and help in redistributing and homogenizing the concrete stress beside the cracks, allowing more short fine diagonal shear cracks with small spacing to develop around the existing cracks. A moderate amount of stirrups can effectively restrain shear cracks and allow more parallel diagonal shear cracks to develop and propagate thoroughly within the shear span. The stiffness of the UHPFRC beams at ultimate state was about 50 % of initial beam stiffness, which was considerable in strength calculations and ductility analysis, especially in seismic performance evaluation. Lastly, the current shear provisions were evaluated using the experimental results.

Objective

To assess the distribution of cervical length (CL) in a large cohort of asymptomatic low‐risk women with singleton pregnancy and no previous preterm birth and to explain the low prevalence of short CL ≤ 30 mm in this cohort.

Methods

This was a secondary analysis of a multicenter cohort study with an embedded randomized controlled trial (Triple P trial; NTR‐2078) on the prevention of preterm birth with progesterone. In the cohort study, CL was measured in asymptomatic low‐risk women with singleton pregnancy to investigate its predictive capacity to identify those at increased risk for preterm birth. A short CL was defined by a cut‐off value of ≤ 30 mm, based on existing literature. Women with a short CL were subsequently included in a randomized controlled trial evaluating the effect of progesterone, compared with placebo, on preterm birth. In total, 57 centers and 20 234 women participated in the study. Normal distributions for CL were simulated based on the mean and SD of the original data. The distribution of CL was assessed for each individual center and measurements were compared between levels of care: primary (29 ultrasound centers), secondary (21 general hospitals) and tertiary (seven university medical centers) care institutions. Comparison was also performed between centers with low, intermediate and high volume of CL measurements. CL distributions before (n = 12 284 women) and after (n = 7950 women) a national symposium, at which the prevalence of short CL measurements was addressed publicly, were analyzed.

Results

Between November 2009 and August 2013, 20 234 women had CL measurements, of whom 367 (1.8%) had a short CL. Mean ± SD CL was 44.2 ± 7.8 mm. A ‘dip’ in the distribution of CL measurements between 20 and 30 mm was observed, defined by a ratio of < 50% when comparing the number of measurements in observed and simulated normal distributions. The dip was present in 89% of participating centers. All centers showed a dip in the distribution of measurements ≤ 30 mm when analyzed according to the level of care and volume of measurements. A significant difference was found when comparing the distribution before and after publicly addressing the low prevalence of short CL (1.7% vs 2.0% of measurements were ≤ 30 mm, respectively; P < 0.001).

Conclusions

A cut‐off value of 30 mm for CL was used to include women in a randomized clinical trial that was embedded in a cohort study. We suggest that the use of a predefined cut‐off value for a short cervix influences the distribution of the CL measurements. Since the measurement is not blinded, preference of assessors for the control or intervention arms may have introduced selection bias. This might have resulted in fewer measurements around the cut‐off value. Other trials using similar designs could benefit from this observation and take precautions to avoid selection bias.

Authors: Degarege A. , Yimam Y. , Madhivanan P. , Erko B.
Published: May 2016

The current study was conducted to evaluate the nature of association of ABO blood type with helminth infection and related reduction in haemoglobin concentration. Stool samples were collected from 403 school-age children attending Tikur Wuha Elementary School from February to April 2011. Helminth infection was examined using formol-ether concentration and thick Kato–Katz (two slides per stool specimen) techniques. Haemoglobin level was determined using a HemoCue machine and ABO blood type was determined using the antisera haemagglutination test. Nutritional status was assessed using height and weight measurements. Out of 403 children examined, 169, 120, 96 and 18 had blood type O, A, B and AB, respectively. The prevalences of helminth infections were 46.9% for hookworm, 24.6% forSchistosoma mansoni, 4.2% forAscaris lumbricoides, 1.7% forTrichuris trichiuraand 58.3% for any helminth species. The relative odds of infection with at least one helminth species was significantly higher among children with blood type A (adjusted odds ratio (AOR), 2.10; 95% confidence interval (CI), 1.28–3.45) or blood type B (AOR, 2.08; 95% CI, 1.22–3.56) as compared to children with blood type O. Among children infected with helminths, mean haemoglobin concentration was lower in those with blood type A than those with blood type O (β, −0.36; 95% CI, −0.72 to −0.01). The relative odds of hookworm infection (AOR, 1.78; 95% CI, 1.08–2.92) and related reduction in haemogobin levels (β, −0.45; 95% CI, −0.84 to −0.04) was higher among children with blood type A as compared to those with blood type O. Although the difference was not significant, the relative odds ofS. mansoniorA. lumbricoidesinfections and related reduction in haemoglobin levels was also higher in children with blood type A or B as compared to children with blood type O. In conclusion, children with blood type A are associated with an increased risk of helminth, particularly hookworm, infection and related reduction in haemoglobin level. The mechanisms by which blood type A makes children susceptible to helminth infection and a related reduction in haemoglobin level ought to be investigated.
Assortative epibiosis of leatherback, olive ridley and green sea turtles in the Eastern Tropical Pacific

Published: May 2016

Sea turtles host a diverse array of epibionts, yet it is not well understood what factors influence epibiont community composition. To test whether epibiont communities of sea turtles are influenced by the hosts’ nesting or foraging habitats, we characterized the epibiota of leatherback, olive ridley and green turtles nesting at a single location on the Pacific coast of Costa Rica. We also compared the epibiota of these turtles to conspecific populations nesting elsewhere in the East Pacific. If epibiont communities are influenced by nesting habitats, we predicted that sympatrically nesting turtles would have comparable epibiont taxa. Alternatively, if epibiont communities are influenced by foraging habitats, we predicted the diversity of epibiont taxa should reflect the type and diversity of the hosts’ foraging habitats. We identified 18 epibiont taxa from 18 leatherback, 19 olive ridley and six green turtles. Epibiont diversity was low on leatherbacks (four taxa), but higher for olive ridley and green turtles (12 and nine epibiont taxa respectively). The epibiont communities of olive ridley and green turtles were not statistically different, but both were different from leatherbacks. In addition, conspecific sea turtles from other nesting locations hosted more similar epibiont communities than sympatrically nesting, non-conspecifics. We conclude that epibiont diversity of nesting sea turtles is partially linked to the diversity of their foraging habitats. We also conclude that the surface properties of the skin and carapace of these turtles may contribute to the uniqueness of leatherback turtle epibiont communities and the similarities between olive ridley and green turtle epibiont communities.

Published: May 2016

Background

Hippocampal volume reductions in major depression have been frequently reported. However, evidence for functional abnormalities in the same region in depression has been less clear. We investigated hippocampal function in depression using functional magnetic resonance imaging (fMRI) and neuropsychological tasks tapping spatial memory function, with complementing measures of hippocampal volume and resting blood flow to aid interpretation.

Method

A total of 20 patients with major depressive disorder (MDD) and a matched group of 20 healthy individuals participated. Participants underwent multimodal magnetic resonance imaging (MRI): fMRI during a spatial memory task, and structural MRI and resting blood flow measurements of the hippocampal region using arterial spin labelling. An offline battery of neuropsychological tests, including several measures of spatial memory, was also completed.

Results

The fMRI analysis showed significant group differences in bilateral anterior regions of the hippocampus. While control participants showed task-dependent differences in blood oxygen level-dependent (BOLD) signal, depressed patients did not. No group differences were detected with regard to hippocampal volume or resting blood flow. Patients showed reduced performance in several offline neuropsychological measures. All group differences were independent of differences in hippocampal volume and hippocampal blood flow.

Conclusions

Functional abnormalities of the hippocampus can be observed in patients with MDD even when the volume and resting perfusion in the same region appear normal. This suggests that changes in hippocampal function can be observed independently of structural abnormalities of the hippocampus in depression.

Published: May 2016

Background

Patients with a deletion at chromosome 22q11.2 (22q11DS) have 30% lifetime risk of developing a psychosis. People fulfilling clinical criteria for ultra-high risk (UHR) for psychosis have 30% risk of developing a psychosis within 2 years. Both high-risk groups show white-matter (WM) abnormalities in microstructure and volume compared to healthy controls (HC), which have been related to psychotic symptoms. Comparisons of WM pathology between these two groups may specify WM markers related to genetic and clinical risk factors.

Method

Fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD) and mean diffusivity (MD) were assessed using diffusion tensor magnetic resonance imaging (MRI), and WM volume with structural MRI, in 23 UHR patients, 21 22q11DS patients, and 33 HC.

Results

Compared to UHR patients 22q11DS patients had (1) lower AD and RD in corpus callosum (CC), cortical fasciculi, and anterior thalamic radiation (ATR), (2) higher FA in CC and ATR, and (3) lower occipital and superior temporal gyrus WM volume. Compared to HC, 22q11DS patients had (1) lower AD and RD throughout cortical fasciculi and (2) higher FA in ATR, CC and inferior fronto-occipital fasciculus. Compared to HC, UHR patients had (1) higher mean MD, RD, and AD in CC, ATR and cortical fasciculi, (2) no differences in FA.

Conclusions

UHR and 22q11DS patients share a susceptibility for developing psychosis yet were characterized by distinct patterns of WM alterations relative to HC. While UHR patients were typified by signs suggestive of aberrant myelination, 22q11DS subjects showed signs suggestive of lower axonal integrity.

Limited information is available on the incidence of Clostridium difficile infections (CDIs) in Italian hospitals. In this study, we assessed the changes in the incidence of CDI over a 5-year period in a teaching hospital in Liguria, the Italian region with the oldest population. Secondary endpoints were the development of severe CDI and 30-day mortality. The annual incidence of CDI/10000 patient-days significantly increased from 0·54 in 2010 to 3·04 in 2014 (χ2 for trend, P < 0·001). The median age of patients with CDI was 81 years. As many as 81% and 89% of these patients had comorbid conditions and previous exposure to antibiotics, respectively. In the multivariate analysis of risk factors for severe CDI, previous therapy with histamine 2 blockers and low serum albumin were associated with severe CDI, while diabetes appeared to be protective. In the multivariate model of risk factors for 30-day mortality, high leukocyte count, low serum albumin, and increased serum creatinine were unfavourably associated with outcome. Strict adherence to infection control measures was of utmost importance to counteract the increasing incidence of CDI in our hospital, particularly because of the advanced age of the patients and their very high frequency of chronic conditions and use of antibiotics, which readily predispose them to the development of CDI.
Food-choice motives of adolescents in Jakarta, Indonesia: the roles of gender and family income
Authors: Maulida Rizka , Nanishi Keiko , Green Joseph , Shibanuma Akira , Jimba Masamine
Published: May 2016

Objective

The aims of the present study were to assess the reliability and validity of the Food Choice Questionnaire (FCQ) and to determine the factors associated with food-choice motives in public junior-high-school students in Jakarta, Indonesia.

Design

Cross-sectional study with self-administered questionnaires. Trained research assistants measured height and weight of the participants on the day of the data collection.

Settings

Fourteen randomly selected public junior-high schools in East Jakarta, Indonesia.

Subjects

Public junior-high-school students (n681) in grades 7 and 8, aged 13–14 years (377 girls and 304 boys).

Results

Three food-choice motives (subscales) were obtained from factor analysis and reliability testing: (i) comfort; (ii) convenience and price; and (iii) health. The subscale with the greatest mean value was health. Family affluence was inversely associated with the convenience and price subscale (β=−0·05,P=0·01) and with the health subscale (β=−0·04;P=0·02). Females were less likely than males to consider health when choosing foods (β=−0·16;P=0·03).

Conclusions

While its factor structure differed from those found in previous studies of adults, the FCQ can provide reliable measures of food-choice motives among these adolescents. Students from less affluent families placed more importance on food’s convenience and price, but more affluent students did not necessarily make healthier choices. Compared with females, males were more likely to choose healthy foods. Future interventions should be tailored based on the socio-economic status of the target group.
Paraventricular Nucleus Modulates Excitatory Cardiovascular Reflexes during Electroacupuncture
Authors: Tjen-A-Looi Stephanie C. , Guo Zhi-Ling , Fu Liang-Wu , Longhurst John C.
Published: May 2016

The paraventricular nucleus (PVN) regulates sympathetic outflow and blood pressure. Somatic afferent stimulation activates neurons in the hypothalamic PVN. Parvocellular PVN neurons project to sympathoexcitatory cardiovascular regions of the rostral ventrolateral medulla (rVLM). Electroacupuncture (EA) stimulates the median nerve (P5-P6) to modulate sympathoexcitatory responses. We hypothesized that the PVN and its projections to the rVLM participate in the EA-modulation of sympathoexcitatory cardiovascular responses. Cats were anesthetized and ventilated. Heart rate and mean blood pressure were monitored. Application of bradykinin every 10-min on the gallbladder induced consistent pressor reflex responses. Thirty-min of bilateral EA stimulation at acupoints P5-P6 reduced the pressor responses for at least 60-min. Inhibition of the PVN with naloxone reversed the EA-inhibition. Responses of cardiovascular barosensitive rVLM neurons evoked by splanchnic nerve stimulation were reduced by EA and then restored with opioid receptor blockade in the PVN. EA at P5-P6 decreased splanchnic evoked activity of cardiovascular barosensitive PVN neurons that also project directly to the rVLM. PVN neurons labeled with retrograde tracer from rVLM were co-labeled with μ-opioid receptors and juxtaposed to endorphinergic fibers. Thus, the PVN and its projection to rVLM are important in processing acupuncture modulation of elevated blood pressure responses through a PVN opioid mechanism.
