Work-related neck and upper limb disorders - Quantitative exposure-response relationships adjusted for personal characteristics and psychosocial conditions

Background: We have previously reported quantitative exposure-response relationships between physical exposures recorded by technical methods, and complaints and diagnoses in the neck/shoulders, and the elbows/hands, based on group data. In the present study the number of workers was doubled, and information on individual factors, and psychosocial working conditions was used. Relationships between

Ultrafast demagnetisation and precessional dynamics in GdFeCo thin Films using a new pump-probe system in the sub-8 femtosecond range

New techniques capable of accessing ultrafast demagnetisation processes on the sub-10 femtosecond timescale are presently in great demand. Achieving a high temporal resolution in pump-probe time-resolved experiments is very important for studying ultrafast processes in matter, providing an ideal platform for understanding interaction mechanisms, such as the spin-orbit coupling, the exchange intera

The association between smoking and knee osteoarthritis in a cohort of Danish patients undergoing knee arthroscopy

Background: It has been suggested that smoking is associated with reduced risk of knee osteoarthritis (OA). However, supplementary studies are needed to further investigate any such potential association. Thus, our aim was to examine the relationship between smoking and early or more established knee OA in a cohort of relatively young patients with meniscal tears. Methods: This cross-sectional stu

Evidence for molecular structural variations in the cytoarchitectures of a Jurassic plant

In this study, we investigate the molecular structural characteristics of organic remains in various cellular organelles from a 180 Ma Jurassic royal fern belonging to the Osmundaceae family of ferns, and compare their carbon isotopic compositions to a now-living species of royal fern (Osmunda regalis). We discovered molecular structural variations indicated by Raman and infrared spectral paramet

Generation of XUV supercontinua through control of attosecond pulse interferences

The generation of XUV supercontinua is of high interest for different applications in that region of the spectrum, such as spectral interferometry and spectroscopy. In high-order harmonic generation (HHG) supercontinua are usually obtained only when a single attosecond pulse is produced, but this implies gating techniques or sub-3-fs IR driving pulses. In this work we demonstrate a new approach fo

Impacts of extreme climate conditions due to climate change on the energy system design and operation

Extreme climate events occur more frequently and stronger in the future due to climate change. Maintaining the energy security during extreme conditions is essential to reduce the impacts of extreme climate and avoid disasters. Resilient design of the energy system to resist against extreme climate events are investigated considering four scenarios, namely, typical demand (TD), extreme demand (ED)

Meta-analysis of fecal metagenomes reveals global microbial signatures that are specific for colorectal cancer

Association studies have linked microbiome alterations with many human diseases. However, they have not always reported consistent results, thereby necessitating cross-study comparisons. Here, a meta-analysis of eight geographically and technically diverse fecal shotgun metagenomic studies of colorectal cancer (CRC, n = 768), which was controlled for several confounders, identified a core set of

IEEE Std. P1687.1: Access to IEEE Std. 1687 via UART

The IEEE Std. P1687.1 is exploring alternatives to IEEE Std. 1149.1 test access port for accessing IEEE Std. 1687 scan networks of instruments. In this paper, we investigate the use of universal asynchronous receiver-transmitter (UART) to access IEEE Std. 1687 networks. We have developed a protocol to describe scan-data transported over UART and a hardware component to translate (retarget) informa

Antiparasitic metabolites from hyptis brevipes, a tacana medicinal plant

A bioassay screening against protozoa parasites of several Tacana medicinal plants gave Hyptis brevipes (Id'ene eidhue), traditionally used as decoction for intestinal parasites, as the most active extract. In this work we did a bioguided isolation of active constituents found in leaves. Structure elucidation was carried out by NMR spectroscopy and MS spectrometry analyses. Active constituents sho

The gracilis tendon autograft is a safe choice for orthopedic reconstructive procedures : A consecutive case series studying the effects of tendon harvesting

Background: The gracilis tendon is commonly used as an autograft to reconstruct torn tendons or ligaments in many parts of the body. Little is known about the subjective and functional outcome after gracilis tendon harvest. The aim of this study was to evaluate the outcome of the donor leg in patients undergoing such surgery. Methods: Patients with chronic acromioclavicular joint dislocations unde

Investigation of self-reported dizziness in the elderly when lying down or turning over in bed, and possible benign paroxysmal positional vertigo

ObjectivesThis study aimed to investigate the rate of dizziness and occurrence of benign paroxysmal positional vertigo in the elderly by physical examination in those reporting dizziness symptoms when lying down or turning over in bed.MethodsA total of 498 people, aged 70-85 years, were asked to complete a questionnaire regarding dizziness symptoms. Subjects answering that they became dizzy in bed

Boredom and homelessness : A scoping review

Background: Emerging literature suggests that boredom is a frequent problem experienced by homeless persons that may influence their health and well-being. Purpose: The range and breadth of literature exploring boredom among homeless persons is unknown. We initiated this study to fill this gap in existing literature. Method: Using the method advanced by Arksey and O’Malley (2005), and furthered by

MiR-378a suppresses tenogenic differentiation and tendon repair by targeting at TGF-β2

Background: Tendons are a crucial component of the musculoskeletal system and responsible for transmission forces derived from muscle to bone. Patients with tendon injuries are often observed with decreased collagen production and matrix degeneration, and healing of tendon injuries remains a challenge as a result of limited understanding of tendon biology. Recent studies highlight the contribution

The impact of perioperative care on complications and short term outcome in ARM type rectovestibular fistula : An ARM-Net consortium study

Background: The impact of perioperative care interventions on postreconstructive complications and short-term colorectal outcome in patients with anorectal malformation (ARM) type rectovestibular fistula is unknown. Methods: An ARM-Net consortium multicenter retrospective cohort study was performed including 165 patients with a rectovestibular fistula. Patient characteristics, perioperative care i

MPEG reconfigurable video coding

The current monolithic and lengthy scheme behind the standardization and the design of new video coding standards is becoming inappropriate to satisfy the dynamism and changing needs of the video coding community. Such a scheme and specification formalism do not enable designers to exploit the clear commonalities between the different codecs, neither at the level of the specification nor at the le

Knowledge and Practices of Colorectal Cancer Early Detection Examinations in Jordan : A Cross Sectional Study

Background: Globally, colorectal cancer (CRC) is ranked the third most common cancer among men and the second in women. The American Cancer Society recommends that starting from the age 50 years, both men and women should be screened for polyps and for early detection of CRC. In Jordan, CRC is the most common cancer among males and the second most common cancer among females. This study aims to as

Consequences of planetary migration on the minor bodies of the early solar system

Pebble accretion is an efficient mechanism that is able to build up the core of the giant planets within the lifetime of the protoplanetary disc gas-phase. The core grows via this process until the protoplanet reaches its pebble isolation mass and starts to accrete gas. During the growth, the protoplanet undergoes a rapid, large-scale, inward migration due to the interactions with the gaseous prot
