Canopy Roughness:A New Phenotypic Trait to Estimate Aboveground Biomass from Unmanned Aerial System

2003年

作者： monica Morrow Virgil Craig Jordan

ISBN: (纸本)155009260X;9781550092608

"Managing Breast Cancer Risk" is a single source for information needed by primary care physicians, nurses, gynaecologists, as well as oncologic specialists who deal with women who are concerned about breast cancer. Its purpose is to bring together a multidisciplinary group of experts to address breast cancer risk in a clinically meaningful way. Chapters providing detailed information on individual risk factors are accompanied by a discussion of models, which integrate multiple factors for a more complete assessment of risk. Traditional strategies for risk management, including surveillance and prophylactic surgery, are reviewed, and the data on newer techniques such as ductal lavage and screening with magnetic resonance is presented. The rational for chemoprevention with selective oestrogen receptor modulators (SERMS) is discussed, and the evidence for tamoxifen as a chemopreventative is updated. The potential for chemoprevention with newer SERMS and the aromatase inhibitors is reviewed. Finally, the critical (and often ignored) areas of quality of life and symptom management are addressed

The effects of climate change on organisms are now being extensively studied in many different taxa. However, the variation in body size, usually shrinkage in response to increasing temperature, has received little attention regarding to reptiles. During past periods of global warming, many organisms shrank in size, and current evidence and experiments manipulating temperature have shown a biomass decrease in some organisms with increasing temperatures. Here we test whether the body size of the Montpellier snake from the southeastern Iberian Peninsula is changing and correlated with the increasing temperature in this region during a 39-year period (1976-2014). We measured the snout-vent length (SVL) of vouchers in scientific collections to check for trends in adult body size at the population level in relation with temperature, while controlling for the age of the individuals (estimated by skeletochronology, =141). Given the great ontogenetic variation in body size of the study species, we categorized age in 3 classes: "young adults" (under 5 years old), "intermediate adults" (from 5 to 7 years old), and "old adults" (from 8 to 14 years old). By means of linear mixed models, we found a negative relationship between SVL of "old adults" and average annual temperature in the region during the lifetime of each individual. Our results indicate that largest and oldest individuals of the Montpellier Snake, that is, males because of strong sexual size dimorphism in this species, disappeared from the study population, and suggest that it occurred in response to rising environmental temperature.

Erectile dysfunction （ED） is considered a condition with a broad range of etiologies. Obstructive sleep apnea （OSA） syndrome is one of the lesser studied risk factors for ED. We intend to summarize the current evidence on the relationship between OSA and sexual impairment, focusing on the results in terms of erectile function of the different therapies offered to OSA patients. A systematic review was conducted, selecting articles related to the physiology of OSA and ED, and to the treatments of OSA syndrome and their reported outcomes in erectile and sexual function. Higher prevalences of ED in the OSA groups have been published. However, whether this effect on the erectile function occurs in the entire range of OSA severities remains unclear. Several hypotheses were proposed to explain the physiology of this association. Continuous Positive Airway Pressure as a treatment for OSA patients with ED has achieved a significative improvement in the sexual parameters in most of the studies. Phosphodiesterase type 5 inhibitors （iPDE5） on demand are useful as a treatment for ED in this subgroup of patients, with high satisfaction rates. The surgical treatment for the OSA evidenced benefits over the erectile function, and the effect on the sexual satisfaction of the therapy using Mandibular Advancement Devices is still undefined.
