Phelipanche ramosa is a major root-holoparasitic damaging weed characterized by a broad host range, including numerous Fabaceae species. In France, the agricultural threat posed by P. ramosa has increased over two decades due to the appearance of a genetically differentiated pathovar presenting a clear host specificity for oilseed rape. The new pathovar has led to a massive expansion of P. ramosa in oilseed rape fields. The germination rate of P. ramosa seeds is currently known to vary among P. ramosa pathovars and host species...

Etiology diagnosis of pleural effusion is a commonly encountered yet challenging problem. How to make the best use of pleural effusion evokes thinking. Myelomatous pleural effusion (MPE) is a rare condition and has been reported sporadically. We report an extremely rare case of multiple myeloma (MM) [IgD-lambda (λ) type, stage III B] with MPE as initial presentation and complicated with massive pericardial effusions during the progression of the disease. Cytological identification of malignant plasma cells in pleural effusion is the most direct method to diagnose MPE...

REVIEW
James C L Chow
Recent rapid development of Internet-based computer technologies has made possible many novel applications in radiation dose delivery. However, translational speed of applying these new technologies in radiotherapy could hardly catch up due to the complex commissioning process and quality assurance protocol. Implementing novel Internet-based technology in radiotherapy requires corresponding design of algorithm and infrastructure of the application, set up of related clinical policies, purchase and development of software and hardware, computer programming and debugging, and national to international collaboration...

BACKGROUND: Before German reunification, old-age mortality was considerably higher in East Germany than West Germany but converged quickly afterward. Previous studies attributed this rapid catch-up to improved living conditions. We add to this discussion by quantifying for the first time the impact of mortality selection. METHODS: We use a gamma-Gompertz mortality model to estimate the contribution of selection to the East-West German mortality convergence before and after reunification...

Ages of jolthead porgy (Calamus bajonado Schneider 1801) (n = 635) from Florida commercial and recreational fisheries from 2008-2016 were determined using sectioned sagittal otoliths. We determined, using edge-type analysis, that opaque zones were annular, forming March-June (peaking in April). Jolthead porgy ranged from 1-13 years, and the largest fish measured 680 mm TL (total length, mm). Body size relationships for jolthead porgy were TL = 1.09FL + 20.44 (n = 622, r(2) = 0.99), FL = 0.90 TL -14...

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities in this river are among the highest recorded on the continent. Understanding the causative factors behind erratic recruitment in this commercially-harvested invasive species is important for both limiting their spread and managing their harvest...

Selective harvest policies have been implemented in North America to enhance the conservation of Pacific salmon (Oncorhynchus spp.) stocks, which has led to an increase in the capture and release of fish by all fishing sectors. Despite the immediate survival benefits, catch-and-release results in capture stress, particularly at high water temperatures, and this can result in delayed post-release mortality minutes to days later. The objective of this study was to evaluate how different water temperatures influenced heart rate disturbance and recovery of wild sockeye salmon (Oncorhynchus nerka) following fisheries interactions (i...

BACKGROUND: Three-dimensional echocardiography. (3DE) is comparable to cardiac magnetic resonance imaging for estimating ventricular volume in congenital heart diseases. However, there are limited data on estimation of ventricular volumes by 3DE in univentricular heart and change in ventricular volumes after surgical creation of cavopulmonary connection. We sought to quantify the unloading of the single ventricle of left ventricular. (LV) morphology by 3DE after superior cavopulmonary anastomosis...

BACKGROUND: Early adoption of technology is a struggle well known to early adopters and now to me. Since the demand to use and implement technology in health professions' education has increased, I have been led to adopt various technologies, leading to many headaches. METHODS: This paper addresses my experiences in developing and implementing technology in health science classrooms in a setting not adequately equipped to do so. RESULTS: After reflecting on my experiences, I conclude that it is crucial that systems help innovators and early adopters as they work to develop and implement teaching and learning technology...

Hypoxia during embryonic growth in embryos is frequently a powerful determinant of development, but at least in avian embryos the effects appear to show considerable intra- and inter-specific variation. We hypothesized that some of this variation may arise from different protocols that may or may not result in exposure during the embryo's critical window for hypoxic effects. To test this hypothesis, quail embryos (Coturnix coturnix) in the intact egg were exposed to hypoxia (~15% O2) during "early" (Day 0 through Day 5, abbreviated as D0-D5), "middle" (D6-D10) or "late" (D11-D15) incubation or for their entire 16-18 day incubation ("continuous hypoxia") to determine critical windows for viability and growth...

Phenotypic plasticity allows organisms to adapt quickly to local environmental conditions and could facilitate adaptive radiations. Cichlids have recently undergone an adaptive radiation in Lake Malawi where they inhabit diverse light environments and tune their visual sensitivity through differences in cone opsin expression. While cichlid opsin expression is known to be plastic over development, whether adults remain plastic is unknown. Adult plasticity in visual tuning could play a role in cichlid radiations by enabling survival in changing environments and facilitating invasion into novel environments...

BACKGROUND AND OBJECTIVE: The sequence of prenatal growth restraint and postnatal catch-up growth may lead to hepato-visceral adiposity, insulin resistance and low-grade inflammation before the onset of puberty. In prepubertal children born appropriate for gestational age (AGA) or small for gestational age (SGA), we assessed potential relationships between the aforementioned sequence and liver volume. SUBJECTS/METHODS: The study population consisted of 86 children (41 AGA and 45 SGA with catch-up growth; age (mean±s...

Several population viability models were constructed to aid recovery in endangered Scaphirhynchus albus, but these models are dependent upon accurate and precise input parameters that are not provided with standard catch per unit effort (CPUE) indices. Nine years of sampling efforts, under the robust design framework, provided 1223 unique captures with an 18·3% recapture rate. The annual population estimates varied from 4·0-7·3 fish rkm(-1) for wild and 8·4-18·4 fish rkm(-1) for hatchery-reared S...

During Drosophila melanogaster oogenesis, spindle assembly occurs without centrosomes and relies on signals from chromosomes. Beaven et al. (2017. J. Cell. Biol. https://doi.org/10.1083/jcb.201704120) show that 14-3-3 proteins bind and inhibit a key microtubule motor, Ncd, during oogenesis, but Aurora B releases Ncd inhibition near chromosomes, allowing Ncd to work in the right time and place.

Individuals relying on natural resource extraction for their livelihood face high income variability driven by a mix of environmental, biological, management, and economic factors. Key to managing these industries is identifying how regulatory actions and individual behavior affect income variability, financial risk, and, by extension, the economic stability and the sustainable use of natural resources. In commercial fisheries, communities and vessels fishing a greater diversity of species have less revenue variability than those fishing fewer species...

PURPOSE: Colorectal cancer (CRC) is the third leading cause of cancer death in the United States, yet 1 in 3 Americans have never been screened for CRC. Annual screening using fecal immunochemical tests (FITs) is often a preferred modality in populations experiencing CRC screening disparities. Although multiple studies evaluate the clinical effectiveness of FITs, few studies assess patient preferences toward kit characteristics. We conducted this community-led study to assess patient preferences for FIT characteristics and to use study findings in concert with clinical effectiveness data to inform regional FIT selection...

OBJECTIVE: The aim of this study was to evaluate the impact of preoperative growth status on clinical outcomes of infantile living-donor liver transplantation (LDLT). METHODS: From January 2009 to December 2014, 131 LDLT recipients ≤1 year of age met the eligibility criteria of this study, of whom 31 patients with weight z-scores less than -2 constituted the abnormal growth group. Patients in the abnormal growth group were randomly matched (1:1) to patients with normal growth status by means of a multivariate case-matched method, and thus 31 patients in the normal growth group and 31 patients in the abnormal growth group were finally enrolled into the study...

BACKGROUND AND AIM: One of the topic issues in animal welfare activities is the free roaming dog welfare especially in developing countries such as Serbia. The way of controlling population of free roaming dogs is their reproduction with the method of "Catch-Neuter-Release." This complex process consists of capturing free roaming dogs in public areas, sterilizing, and returning them to the public area from which they were temporarily removed. Ovariohysterectomy present the period with a high intensity of stress reaction since many veterinarians in Serbia do not use analgesia for this group of dogs...
