Ramie fiber extracted from ramie stem bark (RSB) is a highly important natural fiber, and therefore, RSB is an economically important plant organ. The genetic basis of RSB traits is poorly understood. In the present study, fiber yield and three RSB traits (bark thickness, bark weight, and fiber output ratio) were subject to quantitative trait locus (QTL) analysis using an F2 agamous line population derived from two ramie varieties (Qingdaye and Zhongzhu 1). A total of 4338 high-quality single nucleotide polymorphisms were identified using the genotyping-by-sequencing technique and were subsequently used to construct a high-density genetic map spanning 1942...

The objective of this study was to test the hypotheses that end-test torque (ET) (expressed as % maximal voluntary contraction - MVC) is higher for plantar flexors (PF) than knee extensors (KE) muscles, whereas impulse above ET (IET) is higher for KE than PF. Thus, we expected that exercise tolerance would be longer for KE than PF only during the exercise performed above ET. After the determination of MVC, forty men performed two 5-min all-out tests to determine ET and IET. Eleven participants performed a further four intermittent isometric tests, to exhaustion, at ET + 5% and ET - 5%, and one test for KE at the exercise intensity (%MVC) corresponding to ET + 5% of PF...

Aspects of social support during combat deployment, such as unit cohesion, have been shown to affect later posttraumatic stress disorder (PTSD) development among veterans. We utilized a longitudinal database to assess how relationship quality with fellow soldiers in World War II (WWII) might be linked with postwar PTSD symptoms. Data were available on 101 men who experienced combat exposure in WWII, documented through postwar assessment. Upon study entry (1939 to 1942), data were collected on the quality of participants' early childhood relationships and their emotional adjustment during college...

Introduction: A number of studies have shown a U-shaped association between sleep duration and mortality. Since sleep duration is partly genetically determined, it seems likely that its association with mortality is also genetically influenced. The purpose of the present study was to investigate the influence on heredity on the association between sleep duration and mortality. Methods: We used a cohort of 14267 twins from the Swedish Twin Registry. Results: A Cox proportional hazards regression analysis, adjusted for a number of covariates, confirmed a clear U shape with a hazard ratio (HR) = 1...

American cultural diplomacy played a key role in the institutionalization of Brazilian cardiology. In 1942, Frank Wilson, an internationally recognized pioneer in electrocardiography, made an extended wartime visit to Rio de Janeiro and São Paulo. The visit was sponsored by the United States Department of State as part of Roosevelt's Good Neighbor Policy and brought Wilson together with a group of physicians who would establish the specialty of cardiology in Brazil. This US cultural and diplomatic initiative strengthened an academic network that was already evolving and would eventually prove to be of benefit to both sides...

It can be reasonably assumed that remains exhumed in 2012 and 2013 during archaeological explorations conducted in the Lućmierz Forest, an important area on the map of the German Nazi terror in the region of Lodz (Poland), are in fact the remains of a hundred Poles murdered by the Nazis in Zgierz on March 20, 1942. By virtue of a decision of the Polish Institute of National Remembrance's Commission for the Prosecution of Crimes Against the Polish Nation, the verification of this research hypothesis was entrusted to SIGO (Network for Genetic Identification of Victims) Consortium appointed by virtue of an agreement of December 11, 2015...

Baleen whales are obligate filter feeders, straining prey-laden seawater through racks of keratinized baleen plates. Despite the importance of baleen to the ecology and natural history of these animals, relatively little work has been done on baleen morphology, particularly with regard to the three-dimensional morphology and structure of baleen. We used computed tomography (CT) scanning to take 3D images of six baleen specimens representing five species, including three complete racks. With these images, we described the three-dimensional shape of the baleen plates using cross-sectional profiles from within the gum tissue to the tip of the plates...

OBJECTIVE: To determine the association between maternal obesity and delivery due to chorioamnionitis prior to labor onset, among expectantly managed women with preterm premature rupture of membranes (pPROM). METHODS: This was a secondary analysis of a multicenter randomized trial of magnesium sulfate versus placebo to prevent cerebral palsy or death among offspring of women with anticipated delivery at 24-31-week gestation. After univariable analysis, Cox proportional hazard evaluated the association between maternal obesity and chorioamnionitis, while Laplace regression investigated how obesity affects the gestational age at delivery of the first 20% of women developing the outcome of interest...

Chromosomes of three chalcid wasp species from Brazil, Palmistichus elaeisis Delvare et LaSalle, 1993, Trichospilus diatraeae Cherian et Margabandhu, 1942 (both belonging to the family Eulophidae) and Trichogramma pretiosum Riley, 1879 (Trichogrammatidae), were studied using chromosome morphometrics and base-specific fluorochrome staining. The present study confirmed that these species respectively have 2n = 12, 14 and 10. Chromomycin A3 / 4', 6-diamidino-2-phenylindole (CMA3/DAPI) staining revealed a single CMA3-positive and DAPI-negative band within haploid karyotypes of both Palmistichus elaeisis and Trichogramma pretiosum...

Background: Genetic diversity is an essential resource for breeders to improve new cultivars with desirable characteristics. Recently, genotyping-by-sequencing (GBS), a next-generation sequencing (NGS) technology that can simplify complex genomes, has now be used as a high-throughput and cost-effective molecular tool for routine breeding and screening in many crop species, including the species with a large genome. Results: We genotyped a diversity panel of 369 Iranian hexaploid wheat accessions including 270 landraces collected between 1931 and 1968 in different climate zones and 99 cultivars released between 1942 to 2014 using 16,506 GBS-based single nucleotide polymorphism (GBS-SNP) markers...

BACKGROUND: The elderly population is increasing and more patients in this group undergo Mohs micrographic surgery. The few publications investigating MMS in elderly people conclude that it is a safe procedure; however, these are single centre studies without a comparison group. OBJECTIVE: To compare the characteristics of patients, tumours, MMS, and one-year follow-up in patients younger than 80 years, with patients older than 80 years at the time of surgery. METHODS: Data was analysed from REGESMOHS, a prospective cohort study of patients treated with MMS...

The spatial distribution of receptors within sensory epithelia (e.g. retina and skin) is often markedly non-uniform to gain efficiency in information capture and neural processing. By contrast, odors, unlike visual and tactile stimuli, have no obvious spatial dimension. What need then could there be for either nearest-neighbor relationships or non-uniform distributions of receptor cells in the olfactory epithelium (OE)? Adrian (1942; 1950) provided the only widely debated answer to this question when he posited that the physical properties of odors, such as volatility and water solubility, determine a spatial pattern of stimulation across the OE that could aid odor discrimination...

The scanning electron microscope (SEM) is an electron microscope that produces an image of a sample by scanning it with a focused beam of electrons. The electrons interact with the atoms in the sample, which emit secondary electrons that contain information about the surface topography and composition. The sample is scanned by the electron beam point by point, until an image of the surface is formed. Since its invention in 1942, the capabilities of SEMs have become paramount in the discovery and understanding of the nanometer world, and today it is extensively used for both research and in industry...
