Use of morphometric variables and self-organizing maps to identify clusters of alluvial fans and catchments in the north Peloponnese, Greece
Authors: Karymbalis Efthimios , Ferentinou Maria , Giles Philip T. 
Published: February 2016

Abstract
We applied a computational method to aid in clustering 41 alluvial fans along the southern coast of the Gulf of Corinth, Greece. The morphology of the fans and their catchments was quantitatively expressed through 12 morphometric parameters estimated using geographical information system techniques and the relationships among the geomorphometric features of the fans and their catchments were examined. Self-organizing maps were used to investigate the clustering tendency of fans based on morphometric variables describing both the fans and their corresponding catchments. The results of unsupervised classification through the self-organizing maps method revealed correlations among the morphometric parameters and five groups of alluvial fans were identified. These groups had a clear physical explanation, showed a preferred geographical distribution and reflected the processes related to the development of the fans. The geographical distribution of the fan catchment groups was partially controlled by variations in the relative tectonic uplift rate, which was the main control on the accommodation space for the development and accretion of the fans. The smaller fans were located in the central part of the study area, where the uplift rates were higher, whereas larger fluvial-dominated fan deltas formed to the east and west of the central group, where the uplift rates were lower.

Enhanced Production Level of Quinine in Cell Suspension Culture of Cinchona ledgeriana Moens by Paclobutrazol
Authors: Ratnadewi Diah 
Published: February 2016

Quinine is one of the major alkaloids in Cinchona spp., and it is used both as a medication and as a drink additive. The plant produces most of its alkaloids in the bark after 6â€“8 years of age.Repeated harvests can be performed until the plant dies, but only after every 3â€“5 years. We tested an improved method for culturing cell suspensions of Cinchona ledgerianato investigate the possibility of increasing production of quinine. The clone QRC 315 was treated with either a growth retardant (abscisic acid or paclobutrazol) or precursor feeding of L-tryptophan. To generate stress, we applied mannitol at 5.3 g/L combined with sucrose at a lower concentration (20 g/L),and we used sucrose at 30 g/L as the control. Paclobutrazol (7 mg/L) significantly suppressed cell growth and produced the highest level of quinine (11%) after 7 weeks of culture. L-tryptophan also reduced cell growth, but without any positive effect in the production of quinoline. The highest amount of quinine per culture flask, however, Â resulted in cells treated with 3 mg/L abscisic acid.

SummaryThis study investigated the impact of aerobic exercise on laboratory assessments of haemostatic activity in boys (5–18 years of age) with haemophilia A (HA) or B (HB), examining the hypothesis that laboratory coagulation parameters temporarily improve with exercise. Thirty subjects meeting eligibility criteria (19 HA; 11 HB; mean age: 12.8 years) were invited to participate. They underwent a replacement factor washout period and were advised against strenuous activity for three days prior to the planned intervention. At study visit, baseline blood samples were drawn prior to exercise on a stationary cycle ergometer, aiming to attain 3 minutes (min) of cycling at 85 % of predicted maximum heart rate. Blood work was repeated 5 min (t5) and 60 min (t60) post exercise completion. Samples were assessed for platelet count (PC), factor VIII activity (FVIII:C), von Willebrand antigen (VWF:Ag), ristocetin cofactor activity (VWF:RCo) and platelet function analysis (PFA-100); maximum rate of thrombus generation (MRTG) in blood was measured via thromboelastography and plasma peak thrombin generation (PTG) via calibrated automated thrombography. Mean duration of exercise was 13.9 (± 2.6) min. On average, t5 samples showed significant elevation, relative to baseline in PC, FVIII:C, VWF:Ag, VWF:RCo and PTG, while FVIII:C, VWF:Ag, VWF:RCo and MRTG were significantly elevated in t60 samples. Within the cohort, participants with severe HA showed no change in FVIII:C levels with exercise. The greatest improvement in haemostatic indices was observed in post-adolescent males with mild-moderate HA, who thus represent the group most likely to benefit from a reduction of bleeding risk in the setting of exercise.

Published: February 2016

<p>Excessive water loss during the day due to heat stress in bats of the genus <em>Pteropus</em> appears to be inevitable, because these bats are exposed to direct sunlight. Rain also affects the rest pattern of the Indian Flying Fox <em>Pteropus giganteus </em>during the day. When rain occurred during the day, most of the bats hung in a slanting position and did not exhibit any movements. After rain, they licked both ventral and dorsal surfaces of the wing membrane and scratched their body with their thumb claws. They also licked the water droplets that remained on the leaves and branches of the tree. Even though their rest had been affected by the rain the bats utilized the water droplets to quench their thirst, cool their body and clean their fur. The construction of water reservoirs near <em>Pteropus </em>roosts will help to assure their long-term conservation.</p><div> </div>

Published: February 2016

<p>A morphometric study was performed on six <em>Berlinia </em>species of the Nigerian flora. Individual specimens deposited at Forest Herbarium Ibadan and University of Ibadan Herbarium formed the units of study. Twenty morphological characters were assessed and analyzed following conventional taxonomic practice. Results showed a close resemblance between <em>B. craibiana </em>and <em>B. grandiflora,</em> which share affinity with <em>B. bracteosa </em>and <em>B. confusa</em>,<em> </em>while <em>B. coriacea</em> appears to be distantly related. Species distribution studies revealed that <em>B. grandiflora</em> exists in savanna and forest regions while other members of the genus are found only in forest zones. While suggesting practical measures for conserving endangered Nigerian flora, we also recommend that further taxonomic studies be carried out on the genus <em>Berlinia</em> and its related allies to ascertain their placement within the Caesalpiniodeae.</p><div> </div>

Background—
Prior studies have demonstrated regional left atrial late gadolinium enhancement (LGE) heterogeneity on magnetic resonance imaging. Heterogeneity in regional conduction velocities is a critical substrate for functional reentry. We sought to examine the association between left atrial conduction velocity and LGE in patients with atrial fibrillation.

Methods and Results—

LGE imaging and left atrial activation mapping were performed during sinus rhythm in 22 patients before pulmonary vein isolation. The locations of 1468 electroanatomic map points were registered to the corresponding anatomic sites on 469 axial LGE image planes. The local conduction velocity at each point was calculated using previously established methods. The myocardial wall thickness and image intensity ratio defined as left atrial myocardial LGE signal intensity divided by the mean left atrial blood pool intensity was calculated for each mapping site. The local conduction velocity and image intensity ratio in the left atrium (mean±SD) were 0.98±0.46 and 0.95±0.26 m/s, respectively. In multivariable regression analysis, clustered by patient, and adjusting for left atrial wall thickness, conduction velocity was associated with the local image intensity ratio (0.20 m/s decrease in conduction velocity per increase in unit image intensity ratio,
P
<0.001).

Conclusions—
In this clinical in vivo study, we demonstrate that left atrial myocardium with increased gadolinium uptake has lower local conduction velocity. Identification of such regions may facilitate the targeting of the substrate for reentrant arrhythmias.
Weak Jets and Strong Cyclones: Shallow-Water Modeling of Giant Planet Polar Caps
Authors: O’Neill Morgan E , Emanuel Kerry A. , Flierl Glenn R. 
Published: February 2016

Abstract
Giant planet tropospheres lack a solid, frictional bottom boundary. The troposphere instead smoothly transitions to a denser fluid interior below. However, Saturn exhibits a hot, symmetric cyclone centered directly on each pole, bearing many similarities to terrestrial hurricanes. Transient cyclonic features are observed at Neptune’s South Pole as well. The wind-induced surface heat exchange mechanism for tropical cyclones on Earth requires energy flux from a surface, so another mechanism must be responsible for the polar accumulation of cyclonic vorticity on giant planets. Here it is argued that the vortical hot tower mechanism, claimed by Montgomery et al. and others to be essential for tropical cyclone formation, is the key ingredient responsible for Saturn’s polar vortices. A 2.5-layer polar shallow-water model, introduced by O’Neill et al., is employed and described in detail. The authors first explore freely evolving behavior and then forced-dissipative behavior. It is demonstrated that local, intense vertical mass fluxes, representing baroclinic moist convective thunderstorms, can become vertically aligned and accumulate cyclonic vorticity at the pole. A scaling is found for the energy density of the model as a function of control parameters. Here it is shown that, for a fixed planetary radius and deformation radius, total energy density is the primary predictor of whether a strong polar vortex forms. Further, multiple very weak jets are formed in simulations that are not conducive to polar cyclones.
Has Arctic Sea Ice Loss Contributed to Increased Surface Melting of the Greenland Ice Sheet?
Authors: Liu Jiping , Chen Zhiqiang , Francis Jennifer , Song Mirong , Mote Thomas , Hu Yongyun 
Published: February 2016

Abstract
In recent decades, the Greenland ice sheet has experienced increased surface melt. However, the underlying cause of this increased surface melting and how it relates to cryospheric changes across the Arctic remain unclear. Here it is shown that an important contributing factor is the decreasing Arctic sea ice. Reduced summer sea ice favors stronger and more frequent occurrences of blocking-high pressure events over Greenland. Blocking highs enhance the transport of warm, moist air over Greenland, which increases downwelling infrared radiation, contributes to increased extreme heat events, and accounts for the majority of the observed warming trends. These findings are supported by analyses of observations and reanalysis data, as well as by independent atmospheric model simulations using a state-of-the-art atmospheric model that is forced by varying only the sea ice conditions. Reduced sea ice conditions in the model favor more extensive Greenland surface melting. The authors find a positive feedback between the variability in the extent of summer Arctic sea ice and melt area of the summer Greenland ice sheet, which affects the Greenland ice sheet mass balance. This linkage may improve the projections of changes in the global sea level and thermohaline circulation.
Relationships Among Valued Action, Behavioral Activation, Avoidance, and Reinforcement in a Sample of College Students
Authors: Doi S. , Yokomitsu K. , Sakano Y. 
Published: February 2016

Behavioral activation is a validated intervention for depression, which helps depressed people re-engage overt behaviors to facilitate contacts with reinforcing environmental contingencies and subsequent reductions in depression. Moreover, behavioral activation deals with values that are based on acceptance and commitment therapy. However, there is no empirical study that examines the role of behavior in line with values in behavioral activation. This study examined the role of behavior in line with values in behavioral activation by examining the association between behavior in line with values and variables of behavioral activation intervention targets, as well as the mediating effect of behavioral commitment. Japanese versions of the Personal Values Questionnaire II, the Behavioral Activation for Depression Scale, the Environmental Reward Observation Scale, and the Center for Epidemiological Studies Depression were completed by 292 Japanese undergraduate students ( M age = 19.2 yr., SD = 1.7; 65 men, 226 women, 1 unknown). Results indicated that behavior in line with values was associated with focused, goal-directed activation and completion of scheduled activities, which were mediated by behavioral commitment to values.

Background T2* relaxation is a primary determinant of image contrast with Gradient echo (GRE) sequences, and it has been widely used across body regions. Purpose To compare the diagnostic performance of T2* mapping in combination with T2-weighted (T2W) imaging to T2W imaging alone for prostate cancer (PCa) detection. Material and Methods The study included 31 patients (mean age, 62 ± 3 years; age range, 45–78 years) who underwent magnetic resonance imaging (MRI) at 3.0T and histological examination. Three observers with varying experience levels reviewed T2W imaging alone, T2* mapping alone, and T2W imaging combined with T2* mapping. A five-point scale was used to assess the probability of PCa in each segment on MR images. Statistical analysis was performed using Z tests after adjusting for data clustering. Results The area under the curve (AUC) of T2W imaging and T2* mapping data (observer 1, 0.93; observer 2, 0.90; observer 3, 0.77) was higher than T2W imaging (observer 1, 0.84; observer 2, 0.79; observer 3, 0.69) for all observers ( P < 0.01 in all comparisons). The AUC of T2W imaging and T2* mapping data was higher for observers 1 and 2 than for observer 3 ( P < 0.01). The sensitivity and specificity of T2W imaging and T2* mapping data (observer 1, 95%, 85%; observer 2, 90%, 83%; and observer 3, 82%, 63%, respectively) was higher than T2W imaging (observer 1, 78%, 79%; observer 2, 76%, 72%; observer 3, 74%, 51%, respectively) for all observers ( P < 0.01 for observer 1; P < 0.01 for observers 2 and 3). Conclusion The addition of T2* mapping to T2W imaging improved the diagnostic performance of MRI in PCa detection.

Objective: To investigate the association of cognitive impairment (COGI) and depression with all-cause mortality and cardiovascular-specific mortality among community-dwelling elderly individuals in rural Greece. Methods: Cognition and depressive symptomatology of 676 Velestino town residents aged ≥60 years were assessed using Mini-Mental State Examination (MMSE) and Geriatric Depression Scale (GDS), respectively. Eight-year all-cause mortality and cardiovascular mortality were explored by multivariate Cox regression models controlling for major confounders. Results: Two hundred and one patients died during follow-up. Cognitive impairment (MMSE ≤ 23) was independently associated with all-cause mortality (hazard ratio [HR]: 1.57, 95% confidence interval [CI]: 1.13-2.18) and cardiovascular mortality (HR: 1.57, 95%CI: 1.03-2.41). Moderate to severe depression (GDS > 10) was significantly associated only with a 51% increase in all-cause mortality. A male-specific association was noted for moderate to severe depression, whereas the effect of COGI was limited to females. Noteworthy, COGI and depression comorbidity, rather than their sole presence, increased all-cause mortality and cardiovascular mortality by 66% and 72%, respectively. The mortality effect of COGI was augmented among patients with depression and of depression among patients with COGI. Conclusion: COGI and depression, 2 entities often coexisting among elderly individuals, appear to increase all-cause mortality and cardiovascular mortality. Gender-specific modes may prevail but their comorbidity should be carefully assessed, as it seems to represent an independent index of increased frailty, which eventually shortens life expectancy.

Published: February 2016

Background: The distal tibiofibular syndesmosis is disrupted in up to 45% of operatively treated ankle fractures, and syndesmotic malreduction has historically been correlated with poor outcome. The purpose of this study was to quantify the clamp force used during syndesmotic reduction and to evaluate the effect of clamp force on fibular overmedialization (overcompression) at the level of the distal tibiofibular syndesmosis. Methods: A prospectively recruited cohort of 21 patients underwent operative syndesmotic reduction and fixation. A ball point periarticular reduction forceps that was modified to include a load cell in one tine was used for the reduction, and the clamp force required for reduction was measured. Patients underwent postoperative bilateral computed tomographic scans of the ankle and hindfoot to assess syndesmotic reduction. The uninjured extremity was used as a control. Side-to-side differences in fibular medialization, translation, and rotation within the tibial incisura were measured. These findings were correlated with the reduction clamp force utilized to obtain the reduction. Results: Syndesmotic overcompression (fibular medialization greater than 1.0 mm when compared with noninjured ankle) was seen in 11 of 21 patients (52%). Increased clamp force significantly correlated with syndesmotic overcompression. The mean reduction clamp forces were 88 N for the undercompressed group, 130 N for the adequately compressed group, and 163 N for the overcompressed group. Conclusion: This study demonstrated a significant correlation between increased clamp forces and syndesmotic overcompression, and determined objective forces that lead to overcompression. Our results indicate that surgeons should be cognizant of the clamp force used for syndesmotic reduction. Level of Evidence: Level III, case-control series, in accordance with STROBE guidelines.
