Dispositional empathy is associated with experimental pain reduction during provision of social support by romantic partners
Authors: Duschek Stefan , Nassauer Lena , Montoro Casandra I. , Bair Angela , Montoya Pedro 
Published: August 2019

Abstract

Background and aims
While social interactions like verbal support and physical touch have repeatedly been shown to reduce experimental pain, analgesic effects of passive social support, i.e. the sole physical presence of a supportive other, remain unclear. Moreover, little is known about individual factors influencing the extent of pain attenuation during social support. This study investigated analgesic effects of passive support by a romantic partner and the role of partner empathy therein.

Methods
In 48 heterosexual couples, sensitivity to pressure pain was assessed; each participant was tested alone and in the passive presence of his/her partner. Dispositional empathy was quantified by a questionnaire.

Results
In the presence, as compared to absence, of their partners men and women exhibited higher pain threshold and tolerance, as well as lower sensory and affective pain ratings on constant pressure stimuli. Partner empathy was positively associated with pain tolerance and inversely associated with sensory pain experience.

Conclusions
The results confirm the analgesic effects of social support, which may even occur without verbal or physical contact. Partner empathy may buffer affective distress during pain exposure, thereby reducing pain sensitivity and promoting pain coping. These processes may occur solely due to a partner’s physical presence and do not necessarily require direct empathetic feedback.

Published: August 2019

AbstractThe first part of this two-part article is about a retrospective view of material characterization, starting with the work of J. Epstein around the year 1900 and respective basic explanations. Consequently, the work presented herein is about the current state-of-the-art, recent developments, and future trends in characterization of ferromagnetic materials. Modeling is in fact a type of characterization, in a phenomenological and mathematical sense, and therefore it is treated with due attention in this article. Quantifying the properties of soft magnetic materials retains significant scientific attention. Thanks to new optimization techniques and advances in numerical evaluation, modern electromagnetic devices feature high utilization. Classical models exhibit assumptions that do not allow modern machine or device characterization with high accuracy. In this manuscript, typically applied techniques and recent incremental improvements, as well as newly developed models are introduced and discussed. Moreover, the significant impact of manufacturing on the materials’ characteristics and its quantification is illustrated. Within this article, a broad overview of the state-of-the-art as well as recent advances and future trends in soft magnetic material characterization is presented. Thus, it is a valuable reading for beginners and experts, from academia and industry alike.

ABSTRACT
This review aims to provide an overview of the current load-velocity (L-V) approaches and their ability to estimate one-repetition maximum (1RM). The bench press exercise appears to be the most valid and reliable when applying this approach. The ability for L-V relationship to predict 1RM for lower-body lifts remains questionable. Individualized regression equations should be used alongside mean velocity when utilizing this method during the bench press. The 2-point method (2 distinguishable loads, as opposed to multiple loads) and normative velocity data (minimal velocity thresholds at 1RM) may provide a novel and practical way to assess athletes' 1RM.

Published: August 2019

ABSTRACTA typical seismic experiment involves installing 10–50 seismometers for 2–3 yr to record distant and local earthquakes, along with Earth’s ambient noise wavefield. The choice of the region is governed by scientific questions that may be addressed with newly recorded seismic data. In most experiments, not all stations record data for the full expected duration. Data loss may arise from defective equipment, improperly installed equipment, vandalism or theft, inadequate power sources, environmental disruptions (e.g., snow covering solar panels and causing power outage), and many other reasons. In remote regions of Alaska and northwestern Canada, bears are a particular threat to seismic stations. Here, we document three recent projects (Southern Alaska Lithosphere and Mantle Observation Network, Fault Locations and Alaska Tectonics from Seismicity, and Mackenzie Mountains EarthScope Project) in which bears were regular visitors to remote seismic stations. For these projects, there were documented bear encounters at 56 out of 88 remote stations and 6 out of 85 nonremote stations. Considering bear‐disrupted sites—such as dug‐up cables or outages—there were 29 cases at remote stations and one case at nonremote stations. We also compile bear encounters with permanent stations within the Alaska Seismic Network, as well as stations of the Alaska Transportable Array. For these two networks, the stations are designed with fiberglass huts that house and protect equipment. Data losses at these networks because of bears are minor (<5%), though evidence suggests they are regularly visited by bears, and data disruptions are exclusively at remote stations. The primary goal of this study is to formally document the impacts of bears on seismic stations in Alaska and northwestern Canada. We propose that the threat of damage from bears to a station increases with the remoteness of the site and the density of bears, and it decreases with the strength and security of materials used. We suggest that low‐power electric fences be considered for seismic stations—especially for temporary experiments—to protect the equipment and to protect the bears. With the goal of 100% data returns, future seismic experiments in remote regions of bear country should carefully consider the impacts of bears.
Quel futur pour les forêts de production en Amazonie ? Du bilan carbone de l’exploitation forestière à la recherche de compromis entre services écosystémiques (bois d’œuvre, biodiversité et carbone)
Authors: Piponiot Camille 
Published: August 2019

La moitié des forêts tropicales du monde est désignée comme des forêts de production par les services forestiers nationaux. Pour la seule Amazonie brésilienne (400 millions d’hectares), l’exploitation sélective affecte chaque année entre un et deux millions d’hectares. Si l’effet de la déforestation sur les émissions de carbone et les pertes de biodiversité en région tropicale ont fait l’objet de nombreuses études, les impacts à long terme de l’exploitation commerciale de bois sur ces forêts restent à ce jour très peu étudiés. Or, les enjeux sont grandissants pour ces forêts de production. Non seulement elles doivent alimenter le commerce du bois tropical, mais leur rôle dans le stockage de carbone et dans la préservation de la biodiversité est de plus en plus reconnu. La thèse s’organise en trois temps. Premièrement, un modèle de bilan carbone de l’exploitation forestière est développé, et les différences régionales de dynamique de récupération du carbone post-exploitation sont modélisées. Deuxièmement, un modèle de récupération du volume de bois d’œuvre a été développé et calibré à l’échelle amazonienne. Ces résultats ont permis de montrer la lenteur de la récupération du volume de bois en Amazonie, et la non-durabilité des pratiques actuelles d’exploitation. Ces modèles (carbone et bois d’œuvre) ont été élaborés dans un cadre bayésien, avec l’appui et les données du Tropical managed Forest Observatory (TmFO : www.tmfo.org), réseau rassemblant neuf institutions de recherche et plus de 200 parcelles de suivi de la dynamique forestière après exploitation en Amazonie depuis plus de 30 années. Enfin, une analyse comparative de scénarios prospectifs a été effectuée, où les compromis possibles entre services écosystémiques (bois d’œuvre, carbone et biodiversité) ont été explorés par des techniques d’optimisation multicritère.

Case:
A 48-year-old male patient with a type V acromioclavicular injury with a 3-tendon acute cuff tear, anterior glenohumeral dislocation, and an axillary posttraumatic neuropathy is presented. The rotator cuff tear was sutured and an all-arthroscopic–modified coracoclavicular ligaments (CCLs) reconstruction technique was performed with a gracilis tendon graft and a double knotless suture fixation system.

Conclusions:
An arthroscopic approach allows the surgeon to identify and treat associated glenohumeral lesions in type V acromioclavicular dislocations. In addition, the modified CCL reconstruction technique addresses effectively the AC instability.

ABSTRACT
The use of coiled tubing to drill horizontal re-entry wells has received considerable interest in the industry over the last two years. The benefit of being able to drill at balance, safely and in a controlled manner, using nitrogen to reduce down hole pressure while drilling highly depleted reservoirs, provides an advantage over conventional techniques, particularly in reducing impairment to the formation.
The paper describes such a horizontal re-entry drilled in the shallow depleted water flooded reservoir Barenburg in Northern Germany. The scope of work for this project included: –Cutting a window through 6 5/8" and 9 5/8" casing–Drilling a 5 7/8" medium radius curve–Running a 5" liner and a 5 1/2" parasitic string for nitrogen injection–Drilling a 4 3/8" horizontal using nitrogen to maintain a balanced condition–Run open hole logs–Run 3 1/2" slotted liner
The entire program was executed with no intervention from a conventional rig or workover hoist. A special structure to be positioned over the well to support the coiled tubing injector head and to provide a work platform had to be constructed for this type of operation. A dedicated mast for lifting of pipe and down hole tools was placed on the substructure. The development of a surface controlled orienting tool and an adjustable motor provided excellent directional capabilities on a 2 3/8" coiled tubing. This program represents a significant extension of the capabilities of drilling with coiled tubing.
The Effect of Fluid Pressure Decline on Volume Changes of Porous Rocks
Authors: Geertsma J. 
Published: August 2019

Abstract
In order, to obtain a better insight into the pressure-volume-relationship of reservoir rocks, a theory of pore and rock bulk volume variations is presented. The main features of the theory are: it is independent of the shape of the pores and it is essentially based on combining the superposition principle with the reciprocal theorem of Betti and Rayleigh. The main conclusion obtained from this theory is that only three elastic constants and three viscous constants are required for describing pore and rock bulk volume variations if the porosity is explicitly introduced into the treatment.
In addition, reasonable approximations are introduced for the various types of reservoir rock, viz. sandstones, limestones and shales, which lead to simplications of the general formulae. In consequence there is then a further reduction in the number of deformation constants which have to be determined experimentally. It is shown how measurements of these remaining deformation constants can be performed most conveniently.
Finally the application of the theory to reservoir studies is discussed and the translation experimental results obtained in the laboratory into reservoir behaviour is considered.

Abstract
Background

Arsenic (As) toxicity induces a range of metabolic responses in plants, including DNA methylation. The focus of this paper was on the relationship between As-induced long-term stress and plant senescence in the hyperaccumulator Pteris cretica var. Albo-lineata ( Pc -Al).Results

We showed that Pc -Al grown in pots of haplic chernozem contaminated with 100 mg As kg -1 (As 100 ) for 122 days could accumulate more than 2000 and 2800 mg As kg -1 dry matter in old and young fronds, respectively. Analysis of 5-methylcytosine (5mC) in Pc -Al confirmed that the overall DNA methylation status in fronds of As 100 ferns was reduced in contrast to control treatment. Compared with controls, the overall DNA methylation status in fronds of As 100 ferns was reduced (by 6% in young and 10% in old fronds); however, the decrease was significant only in old fronds. The significant correlations for 5mC, in contrast to direct As toxicity, showed that decreases of chlorophylls, fluorescence and photosynthetic rate could be affected by epigenetic changes. Photosynthetic processes were determined in As 100 treatment and showed a reduction of gas-exchange parameters, and a decrease in carotenoids and chlorophylls (by 5% and 26%, respectively). Hyperaccumulation of As resulted in a significant elevation of all analysed nutrients (Cu, Mn, Zn, Mg, S) in old fronds, but not in young fronds.Conclusions

The results of this paper point to complex changes in the metabolism of the hyperaccumulator plant Pc -Al, upon exposure to As contamination. The most significant impact was found in young fronds. The physiological parameters correlated more significantly with a decrease of DNA methylation than with direct As toxicity. Our analysis of the very low water potential values and lignification of cell walls in roots showed that transports of assimilated metabolites and water between roots and fronds were reduced.

Abstract
Background: The BAHD acyltransferase superfamily exhibits various biological roles in plants, including regulation the fruit quality; catalytic synthesis of terpene, phenolic and esters; improvement of stress resistance. However, the copy number, evolutionary history and potential functions of the BAHD superfamily genes in the genome sequenced Rosaceae species remains unclear. Results: Totally, 755 BAHD genes were obtained from the genomes of seven Rosaceae fruit species (Pyrus bretschneideri, Malus domestica, Prunus avium, Prunus persica, Fragaria vesca, Pyrus communis and Rubus occidentalis). Based on the classification results from model plants, we divided the BAHD family genes into seven subgroups (I-a, I-b, II-a, II-b, III-a, IV, V). Based on intra-species synteny analysis, 61 syntenic gene pairs were detected from the six Rosaceae species. Dispersed gene duplication occurred frequently in all investigated species. Different modes of duplicated gene pairs identified in each investigated species show that the Ka/Ks is less than one, indicating they evolved through purifying selection. Based on the correlation analysis between ester content and expression level of BAHD genes at different development stages, we selected five genes to perform qRT-PCR verification, and the results showed that Pbr020016.1, Pbr019034.1, Pbr014028.1 and Pbr029551.1 are the important candidate genes involved in aroma formation during pear fruit development. Conclusion: We have thoroughly annotated the BAHD superfamily genes and made a comprehensive comparative analysis of their colinearity, phylogenetic relationships and gene duplication patterns in the seven Rosaceae species, and also obtained four candidate genes might be involved in the aroma synthesis in the pear fruit. These presented results provide a theoretical basis for the future studies of the specific biological functions of BAHD superfamily members and the improvement of pear fruit quality.

Abstract
Background The X-linked form of Charcot-Marie-Tooth disease type 1(CMTX1) is an inherited peripheral neuropathy that arises in patients with mutations in the gap-junction beta-1 gene (GJB1).
Case presentation Three young male patients from Southern China with pes cavus experienced multiple episodes of transient central nervous system (CNS) dysfunction. Three patients all had reversible posterior leukoencephalopathy as detected by brain diffusion-weighted magnetic resonance imaging (MRI-DWI). Nerve conduction velocity (NCV) showed sensorimotor polyneuropathy with mixed demyelinating and axonal features. Genetic testing indicated a c.425G>A (p. Arg 142 Glu) or c.563 C>T (p. Thr 188 Ile) or c.103G>C (p. Val 35 Leu) mutation in GJB1. The unique feature of this report is two novel mutations: c.563 C>T and sc.103G>C of GJB1 gene detected in two families respectively. Another unique feature is that peripheral neuropathy symptoms in three patients were insidious and found at the onset of CNS symptoms
Conclusions Central nervous system involvement in patients with CMTX1 indicates that myelin damage in the CNS and peripheral nerve system may have similar pathogenetic mechanisms.
