ASSESSING DEER DAMAGE IN YOUNG FRUIT ORCHARDS

Evaluations of systematic damage assessments of 5, 10 and 20 percent of all apple trees in 12 orchards were compared. The 10% assessment technique was selected as the most accurate and efficient in estimating summer and fall damage. Analysis of several parameters of tree vigor found significant differences between browsed and unbrowsed trees for tree basal diameter and central leader diameter over 2 successive years. These subtle yet important differences in tree development were felt to severely limit the possibilities of relating browsing to growth and. later, yields. Methods and considerations for making control decisions on a per acre basis are discussed

Accelerating functional gene discovery in osteoarthritis.

Osteoarthritis causes debilitating pain and disability, resulting in a considerable socioeconomic burden, yet no drugs are available that prevent disease onset or progression. Here, we develop, validate and use rapid-throughput imaging techniques to identify abnormal joint phenotypes in randomly selected mutant mice generated by the International Knockout Mouse Consortium. We identify 14 genes with functional involvement in osteoarthritis pathogenesis, including the homeobox gene Pitx1, and functionally characterize 6 candidate human osteoarthritis genes in mouse models. We demonstrate sensitivity of the methods by identifying age-related degenerative joint damage in wild-type mice. Finally, we phenotype previously generated mutant mice with an osteoarthritis-associated polymorphism in the Dio2 gene by CRISPR/Cas9 genome editing and demonstrate a protective role in disease onset with public health implications. We hope this expanding resource of mutant mice will accelerate functional gene discovery in osteoarthritis and offer drug discovery opportunities for this common, incapacitating chronic disease

‘Browning’ the cardiac and peri-vascular adipose tissues to modulate cardiovascular risk

Excess visceral adiposity, in particular that located adjacent to the heart and coronary arteries is associated with increased cardiovascular risk. In the pathophysiological state, dysfunctional adipose tissue secretes an array of factors modulating vascular function and driving atherogenesis. Conversely, brown and beige adipose tissues utilise glucose and lipids to generate heat and are associated with improved cardiometabolic health. The cardiac and thoracic perivascular adipose tissues are now understood to be composed of brown adipose tissue in the healthy state and undergo a brown-to-white transition i.e. during obesity which may be a driving factor of cardiovascular disease. In this review we discuss the risks of excess cardiac and vascular adiposity and potential mechanisms by which restoring the brown phenotype i.e. “re-browning” could potentially be achieved in clinically relevant populations

Disproportionate presentation of high risk prostate cancer in a safety net health system.

PurposeMost prostate cancer research is based on relatively homogenous cohorts of men, often with comparatively high socioeconomic status. We describe prostate cancer characteristics in men treated in a public health system and hypothesize a disproportionate burden of high risk disease in this population.Materials and methodsWe created a clinical registry from a review of the medical records of 377 men diagnosed with prostate cancer in the San Francisco General Hospital system, which provides care to underserved, uninsured populations. We compared sociodemographic data and cancer characteristics with those in 2 large prostate cancer databases from a community (CaPSURE™) and an academic (University of California-San Francisco tumor registry) setting to assess differences in risk distribution using the D'Amico and Cancer of the Prostate Risk Assessment scoring systems.ResultsCompared to men in CaPSURE or the University of California-San Francisco tumor registry those in the San Francisco General Hospital cohort were nonwhite (76%), insured under Medicaid (31%) or uninsured (8%) and had adverse clinical characteristics, including median prostate specific antigen greater than 10 ng/ml at diagnosis and higher Gleason grade. In addition, the majority of patients (67%) had intermediate or high risk disease based on the D'Amico classification and a higher mean Cancer of the Prostate Risk Assessment score. Using ANOVA for continuous variables and the chi-square test for categorical variables, all comparisons were statistically significant (p <0.001).ConclusionsMen in the San Francisco General Hospital public health system bear a substantially higher burden of high risk disease that those in an academic or a community setting. Populations such as this would benefit most from targeted efforts for early detection and treatment to decrease prostate cancer morbidity and mortality
