We studied by means of Grazing Incidence X-ray Diffraction (GIXD) coupled with X-ray fluorescence spectroscopy the structure of a behenic acid monolayer spread at the surface of Mg2+ /Mn2+ mixed aqueous solutions. For the pure Mg2+ and Mn2+ aqueous solutions, the cations induce at the surface different 2D lattice superstructures of the organic monolayer. These superstructures correspond to an inorganic organized monolayer anchored to the hydrophilic group of the ordered behenic acid monolayer. Among the various diffraction peaks, we focused on those characteristics of the behenic acid oblique cell...

Purpose: Lateral condyle fractures of the humerus are common in the paediatric population, accounting for up to 20% of elbow fractures. Traditional management involves internal fixation with Kirschner (K)-wires, however, this has been associated with complications and insufficiently rigid fixation. Recently, cannulated screws have been proposed as a more stable method of fixation. While cannulated screws have been thought to allow earlier range of movement and shorten time to union, data regarding the biomechanical performance and optimal screw placement is scarce...

Jin Park, Jin Ho Che
Talus fracture of the medial tubercle of the posterior process is rare. This type of fracture can be easily missed, because it is difficult to identify on plain radiographs of the ankle. Oblique radiographs with external rotation, computed tomography, and magnetic resonance imaging (MRI) of the ankle are useful for making an accurate diagnosis. However, even with an early diagnosis, the treatment guidelines for talus fractures of the posterior medial tubercle have not yet been established. The flexor hallucis longus (FHL) tendon, which passes through the groove between the medial and lateral tubercles of the posterior process of the talus, can interpose between the fracture sites and interrupt fracture reduction...

The accuracy of quantitative stereological analysis tools such as the (physical) disector method substantially depends on the precise determination of the thickness of the analyzed histological sections. One conventional method for measurement of histological section thickness is to re-embed the section of interest vertically to its original section plane. The section thickness is then measured in a subsequently prepared histological section of this orthogonally re-embedded sample. However, the orthogonal re-embedding (ORE) technique is quite work- and time-intensive and may produce inaccurate section thickness measurement values due to unintentional slightly oblique (non-orthogonal) positioning of the re-embedded sample-section...

The effect of environmental change on the rate of innovation and level of cultural complexity in a population is a theoretically understudied piece of an important puzzle at the heart of cultural evolution. Many mathematical models of cultural complexity have focused on the role of demographic factors such as population size or density. However, statistical studies often point to environmental variability as an important factor determining complexity in many cases. The aim of this study is to explore the interaction between environmental fluctuations and the rate of cultural innovation within a population and to examine the relationship between rates of innovation and the probability of maintaining a complex cultural repertoire in a changing environment...

Plant root responds to soil moisture gradients through hydrotropism and remodels root growth orientation chasing soil water, a process regarded as plant acclimation to a changing soil environment. Mechanisms underlying the root hydrotropic response, however, remain poorly understood. Here, hydrotropism was examined in 31 Arabidopsis ecotypes collected from different parts of the world and grown along moisture gradients in a specially designed soil-simulation system. More detailed comparative transcriptomic, ionomic profiling, and physiological analyses were carried out on three wild types, Ws (strongly hydrotropic), Col-0 (moderately hydrotropic), and C24 (weakly hydrotropic), and also in mutant lines showing disruptions in the root hydrotropic response...

Pollen from deep-sea sedimentary sequences provides an integrated regional reconstruction of vegetation and climate (temperature, precipitation, and seasonality) on the adjacent continent. More importantly, the direct correlation of pollen, marine and ice indicators allows comparison of the atmospheric climatic changes that have affected the continent with the response of the Earth's other reservoirs, i.e., the oceans and cryosphere, without any chronological uncertainty. The study of long continuous pollen records from the European margin has revealed a changing and complex interplay between European climate, North Atlantic sea surface temperatures (SSTs), ice growth and decay, and high- and low-latitude forcing at orbital and millennial timescales...

Since the original description of side effects of neuroleptics, different terminologies and definitions for tardive dyskinesia (TD) and tardive syndrome (TS) have been used by different authors, and often these two terms have been used interchangeably. This paper proposes a nosology designed to define and clarify various terms and phenomenologies within the TS spectrum. We propose to use the term tardive dyskinesia to refer to the original description of repetitive and complex oral-buccal-lingual (OBL) movements, as well as to the analogous repetitive movements that can appear in the limbs, trunk, or pelvis...

Background: Injury to the infrapatellar branch of the saphenous nerve (IPBSN) is common after arthroscopic ACL reconstruction with hamstring tendon autograft, as reported in up to 88% of the cases. Due to close relationship between the IPBSN with pes anserine tendons insertion skin incision may sever IPBSN while harvesting gracillis and semitendinous tendons. As the IPBSN course at the anterior of knee is oblique, we hypothesized a parallel skin incision with nerve passage may decrease nerve injury...
