Geology and Wine 8. Modeling Viticultural Landscapes: A GIS Analysis of the Terroir Potential in the Umpqua Valley of Oregon
Terroir is a holistic concept that relates to both environmental and cultural factors that together influence the grape growing to wine production continuum. The physical factors that influence the process include matching a given grape variety to its ideal climate along with optimum site characteristics of elevation, slope, aspect, and soil. While some regions have had hundreds and even thousands of years to define, develop, and understand their best terroir, newer regions typically face a trial and error stage of finding the best variety and terroir match. This research facilitates the process by modeling the climate and landscape in a relatively young grape growing region in Oregon, the Umpqua Valley appellation. The result is an inventory of land suitability that provides both existing and new growers greater insight into the best terroirs of the region.
SOMMAIRE
Le terroir est un concept holiste de facteurs environnementaux et culturels agissant sur un continuum s'Ă©tendant de la croissance de la vigne Ă la vinification. Dans le domaine des facteurs physiques, il faut trouver la combinaison idĂ©ale entre la variĂ©tĂ© du raisin d'une part, et le climat et les caractĂ©ristiques du site de culture comme l'Ă©lĂ©vation, la pente, l'aspect et le type de sol, d'autre part. Alors qu'en certaines rĂ©gions, on a eu des centaines, voire des milliers d'annĂ©e pour dĂ©finir, dĂ©velopper et dĂ©finir le terroir idĂ©al, dans les rĂ©gions nouvelles, on doit procĂ©der par essais et erreur pour trouver le meilleur appariement raisin et terroir. La recherche dĂ©crite ci-contre entend faciliter ce processus de mariage idĂ©al en modĂ©lisant les facteurs du climat et du paysage dans une rĂ©gion viticole relativement jeune de l'OrĂ©gon, celle de la vallĂ©e de Umpqua. Le rĂ©sultat obtenu est un inventaire des terrains propices, ce qui fait aussi bien l'affaire des vignerons Ă©tablis que des nouveaux vignerons dans leur quĂȘte des meilleurs terroirs de la rĂ©gion
Deletions within COL11A1 in Type 2 stickler syndrome detected by multiplex ligation-dependent probe amplification (MLPA).
BACKGROUND: COL11A1 is a large complex gene around 250 kb in length and consisting of 68 exons. Pathogenic mutations in the gene can result in Stickler syndrome, Marshall syndrome or Fibrochondrogenesis. Many of the mutations resulting in either Stickler or Marshall syndrome alter splice sites and result in exon skipping, which because of the exon structure of collagen genes usually leaves the message in-frame. The mutant protein then exerts a dominant negative effect as it co-assembles with other collagen gene products. To date only one large deletion of 40 kb in the COL11A1, which was detected by RT-PCR, has been characterized. However, commonly used screening protocols, utilizing genomic amplification and exon sequencing, are unlikely to detect such large deletions. Consequently the frequency of this type of mutation is unknown. CASE PRESENTATIONS: We have used Multiplex Ligation-Dependent Probe Amplification (MLPA) in conjunction with exon amplification and sequencing, to analyze patients with clinical features of Stickler syndrome, and have detected six novel deletions that were not found by exon sequencing alone. CONCLUSION: Exon deletions appear to represent a significant proportion of type 2 Stickler syndrome. This observation was previously unknown and so diagnostic screening of COL11A1 should include assays capable of detecting both large and small deletions, in addition to exon sequencing.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Results of a nine month home-based physical activity intervention for people living with HIV.
Background: The purpose of this investigation was to test the feasibility of a home-based moderate-intensity physical activity (MPA) program for people living with HIV/AIDS (PLWHA) currently taking antiretroviral therapy (ART). Methods: 68 participants recruited for a 9-month home-based PA intervention aimed to reduce risk factors of cardiovascular disease for PLWHA taking ART. All participants received an educational weight loss workbook and a pedometer for self-monitoring of physical activity. The intervention group received elastic TherabandsÂź for strength training in addition to telephone based behavioral coaching. Clinical assessments were conducted at baseline and each follow-up which also included psychometric questionnaires and PA levels via the SenseWearÂź armband accelerometer. Results: Of the 57 completing the study, 29 of those were in the intervention group and 28 were in the standard care group. Results show that the home-based PA intervention was not successful in increasing the total amount of MPA for PLWHA. However there was a trend (p=0.08) of decreasing sedentary time. In a secondary analysis those who increased PA by \u3e10% observed decreases in waist circumference and improved functioning at 18 weeks. None of the changes observed were significant after controlling for all potential confounders. Conclusions: A home-based exercise approach with telephone-based coaching may not be a feasible method for increasing MPA among PLWHA. Slight decreases in sedentary time indicate some positive changes in activity habits. A possible strategy to improve studies similar to this is to incorporate a group based social interaction each week similar to that of a support group
Brain imaging research on psychopathy: Implications for punishment, prediction, and treatment in youth and adults
Imperforated cor triatriatum dexter in a dog with concurrent caudal vena cava wall mineralization
BACKGROUND: Cor triatriatum dexter (CTD) is a rare congenital cardiac malformation with various manifestations and has been sporadically described in dogs. Clinically the dogs present with nonspecific signs of right heart failure or Budd-Chiari-like syndrome. Other associated concurrent cardiovascular anomalies are commonly reported. Diagnosis and full characterization of this complex malformation requires careful investigation and often a multimodal imaging approach

Prevention of retinal detachment in stickler syndrome: the cambridge prophylactic cryotherapy protocol
Purpose
The Stickler syndromes are the most common causes of inherited and childhood retinal detachment; however, no consensus exists regarding the effectiveness of prophylactic intervention. We evaluate the long-term safety and efficacy of the Cambridge prophylactic cryotherapy protocol, a standardized retinal prophylactic treatment developed to prevent retinal detachment arising from giant retinal tears in type 1 Stickler syndrome.
Design
Retrospective comparative case series.
Participants
Four hundred eighty seven patients with type 1 Stickler syndrome.
Methods
Time to retinal detachment was compared between patients who received bilateral prophylaxis and untreated controls, with and without individual patient matching. Patients receiving unilateral prophylaxis (after fellow eye retinal detachment) were similarly compared with an appropriate control subgroup. Individual patient matching ensured equal age and follow-up between groups and that an appropriate control (who had not suffered a retinal detachment before the age at which their individually matched treatment patient underwent prophylactic treatment) was selected. Matching was blinded to outcome events. Individual patient matching protocols purposely weighted bias against the effectiveness of treatment. All treatment side effects are reported.
Main Outcome Measures
Time to retinal detachment and side effects occurring after prophylactic treatment.
Results
The bilateral control group (n = 194) had a 7.4-fold increased risk of retinal detachment compared to the bilateral prophylaxis group (n = 229) (hazard ratio [HR], 7.40; 95% confidence interval [CI], 4.53â12.08; P<0.001); the matched bilateral control group (n = 165) had a 5.0-fold increased risk compared to the matched bilateral prophylaxis group (n = 165) (HR, 4.97; 95% CI, 2.82â8.78; P<0.001). The unilateral control group (n = 104) had a 10.3-fold increased risk of retinal detachment compared to the unilateral prophylaxis group (n = 64) (HR, 10.29; 95% CI, 4.96â21.36; P<0.001); the matched unilateral control group (n = 39) had a 8.4-fold increased risk compared to the matched unilateral prophylaxis group (n = 39) (HR, 8.36; 95% CI, 3.24â21.57; P<0.001). No significant long-term side effects occurred.
Conclusions
In the largest global cohort of type 1 Stickler syndrome patients published, all analyses indicate that the Cambridge prophylactic cryotherapy protocol is safe and markedly reduces the risk of retinal detachment.
