Lower canopy temperature (CT), resulting from increased stomatal conductance, has been associated with increased yield in wheat. Historically, CT has been measured with hand-held infrared thermometers. Using the hand-held CT method on large field trials is problematic, mostly because measurements are confounded by temporal weather changes during the time requiredto measure all plots. The hand-held CT method is laborious and yet the resulting heritability low, thereby reducing confidence in selection in large scale breeding endeavours.We have developed a reliable and scalable crop phenotyping m

Purpose The aim of this study is to examine the tolerability and effect of early high-dose amino acid administration in extremely low birth weight infants (ELBWIs). Methods This retrospective cohort study included ELBWI (birth weight <1,000 g, n=142). Biochemical, nutritional, and neurodevelopmental data were compared between infants who received conventional low amino acid (LAA; 1.5 g/kg/day) and those who received high amino acid (HAA; 3 g/kg/day) within the first 48 hours after birth. Neurodevelopmental data included weight, height, and head circumference at discharge, 12 to 14 and 18 to 24

Background Objective responses to immune checkpoint inhibitors (ICI) in leiomyosarcoma (LMS) are rare. Response rates may be increased by combination with other drugs known to promote immune infiltration, such as poly(ADP-ribose) polymerase (PARP) inhibitors, which have led to benefit in BRCA-altered uterine LMS. We therefore evaluated the combination of a PARP inhibitor, rucaparib, and the anti-programmed death receptor-1 monoclonal antibody, nivolumab, in patients with advanced LMS and investigated its effects on the tumor immune microenvironment.Methods This was an open-label, single-center

Assistance dogs can greatly improve the lives of people with disabilities. However, a large proportion of dogs bred and trained for this purpose are deemed unable to successfully fulfill the behavioral demands of this role. Often, this determination is not finalized until weeks or even months into training, when the dog is close to 2 years old. Thus, there is an urgent need to develop objective selection protocols that can identify dogs most and least likely to succeed, from early in the training process.

The hemolytic uremic syndrome (HUS), characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure, represents one of the major causes of acute renal failure in infancy and childhood. The typical form occurring after an episode of diarrhea caused by Escherichia coli is the most frequent in children. Other microorganisms also may be responsible for HUS, such as Streptococcus pneumoniae, which causes more severe forms of the disease.

Alfalfa is a high-yielding forage crop that is widely grown in the United States for grazing, hay and silage making. A proper maintenance of these grasslands is necessary to ensure optimum productivity and profits. The pre-harvest estimation of biomass yield helps in quantifying the profits and optimizing the forage allocation in advance. Most traditional methods of forage estimation are relatively laborious and time-consuming. Recent developments in contact and remote sensing technologies opened numerous paths for performing aboveground biomass estimation tasks with flexibility and easiness.

Deletion of exon 52 disrupts the expression of two dystrophins found in the brain (Dp427 and Dp140) and is eligible for therapeutic exon-skipping strategies.
