Anurag Pande, Sai Chand, Neeraj Saxena, Vinayak Dixit, James Loy, Brian Wolshon, Joshua D Kent
This paper describes a project that was undertaken using naturalistic driving data collected via Global Positioning System (GPS) devices to demonstrate a proof-of-concept for proactive safety assessments of crash-prone locations. The main hypothesis for the study is that the segments where drivers have to apply hard braking (higher jerks) more frequently might be the "unsafe" segments with more crashes over a long-term. The linear referencing methodology in ArcMap was used to link the GPS data with roadway characteristic data of US Highway 101 northbound (NB) and southbound (SB) in San Luis Obispo, California...

L Allan James
Geomorphic systems often experience morphological changes that define a trajectory over decadal time periods. These trends can be halted by natural inhibitors such as vegetation, knickpoints, bed armor, or bank cohesion, or by anthropogenic inhibitors such as revetment, levees, or dams. Details about where and how channels and floodplains are stabilized are often poorly understood, which poses a risk that modern projects could unwittingly remove critical stabilizing elements (inhibitors) and unleash an episode of rapid change...

Ventricular premature complexes (VPCs) may represent a reversible cause of heart failure (HF); however, the type of patients most prone remains unknown. This study leverages a large population-based database to examine interactions that might prove clinically useful in risk-stratifying patients with VPCs. We used the California Healthcare Cost and Utilization Project to identify patients with VPCs and incident systolic HF from January 1, 2005, to December 31, 2009. We calculated hazard ratios for predictors of incident systolic HF using multivariable Cox proportional hazard models...

REVIEW
Jacqueline M Speed, Quoc-Dien Trinh, Toni K Choueiri, Maxine Sun
PURPOSE OF REVIEW: Patients with localized renal cell carcinoma (RCC) are at risk of recurrence. The purpose of this review was to characterize the literature on recurrence rates and risk factors after diagnosis of localized RCC. RECENT FINDINGS: Our search revealed that existing data examining the prevalence of recurrence rates predominantly originates from cohorts of patients diagnosed and treated in the 1980s to 1990s, and may therefore not be as useful for counseling for current patients today...

PURPOSE: The ER-/PR-/HER2- or triple-negative (TNBC) subtype is more prevalent among women who are young, black, Hispanic, and of lower SES. The purpose of this study is to determine if young age and low SES are associated with TNBC within four mutually exclusive race/ethnicities. METHODS: The study identified 19,283 cases of TNBC and 89,089 of ER+/PR+/HER2- from the California Cancer Registry. Logistic regression analyses were conducted separately for whites, blacks, Hispanics, and Asian/Pacific Islanders (API) to compute the adjusted odds ratios (OR) for age and SES for the TNBC versus the ER+/PR+/HER2- subtype...

The increased availability of nuclear DNA sequence data has led to a better appreciation of the role and frequency of introgressive hybridization and subsequent mitochondrial capture in misleading phylogenetic hypotheses based on mtDNA sequence data alone. Relationships among members of the alligator lizard genus Elgaria have been addressed with morphology, allozyme and mtDNA sequence data with discordant results. In this study, we use seven nuclear loci (total of 5.9 kb) and ∼3 kb of mtDNA to infer the phylogenetic relationships among Elgaria species and test whether the discordance among previous phylogenetic hypotheses is due to introgression and mtDNA capture...

With its high seed oil content, the mustard family plant Camelina sativa has gained attention as a potential biofuel source. As a bioenergy crop, camelina has many advantages. It grows on marginal land with low demand for water and fertilizer, has a relatively short life cycle, and is stress tolerant. As most other crop seed oils, camelina seed triacylglycerols (TAGs) consist of mostly long, unsaturated fatty acyl moieties, which is not desirable for biofuel processing. In our efforts to produce shorter, saturated chain fatty acyl moieties in camelina seed oil for conversion to jet fuel, a 12:0-acyl-carrier thioesterase gene, UcFATB1, from California bay (Umbellularia californica Nutt...

OBJECTIVE: Obesity and stable angina pectoris (SAP) are important public health problems in the USA. However, little is known about whether weight reduction affects the rate of SAP-related morbidities. This study was designed to test the hypothesis that bariatric surgery is associated with a lower rate of hospitalisations for SAP in obese adults. METHODS: We performed a self-controlled case series study of obese adults with SAP who underwent bariatric surgery using a population-based inpatient database in three states (California, Florida and Nebraska) from 2005 to 2011...

INTRODUCTION: The self-etching primer system consists of etchant and primer dispersed in a single unit. The etching and priming are merged as a single step leading to fewer stages in bonding procedure and reduction in the number of steps that also reduces the chance of introduction of error, resulting in saving time for the clinician. It also results in smaller extent of enamel decalcification. AIM: To compare the Shear Bond Strength (SBS) of orthodontic bracket bonded with Self-Etch Primers (SEP) and conventional acid etching system and to study the surface appearance of teeth after debonding; etching with conventional acid etch and self-etch priming, using stereomicroscope...

BACKGROUND: Estimates of economic and social costs related to alcohol and other drug (AOD) use and abuse are usually made at state and national levels. Ecological analyses demonstrate, however, that substantial variations exist in the incidence and prevalence of AOD use and problems including impaired driving, violence, and chronic disease between smaller geopolitical units like counties and cities. This study examines the ranges of these costs across counties and cities in California...

Identifying mechanisms driving pathogen persistence is a vital component of wildlife disease ecology and control. Asymptomatic, chronically infected individuals are an oft-cited potential reservoir of infection but demonstrations of the importance of chronic shedding to pathogen persistence at the population level remain scarce. Studying chronic shedding using commonly collected disease data is hampered by numerous challenges, including short-term surveillance that focuses on single epidemics and acutely ill individuals, the subtle dynamical influence of chronic shedding relative to more obvious epidemic drivers, and poor ability to differentiate between the effects of population prevalence of chronic shedding versus intensity and duration of chronic shedding in individuals...

Marine spatial planning (MSP) is increasingly utilized to sustainably manage ocean uses. Marine protected areas (MPAs), a form of spatial management in which parts of the ocean are regulated to fishing, are now a common tool in MSP for conserving marine biodiversity and managing fisheries. However, the use of MPAs in MSP often neglects, or simplifies, the redistribution of fishing and non-fishing activities inside and outside of MPAs following their implementation. This redistribution of effort can have important implications for effective MSP...

The project goal was to determine how a new vector control strategy that targets the sugar-feeding behavior of mosquitoes, attractive toxic sugar baits (ATSBs), can be used to more effectively control West Nile virus (WNV) vectors in the Coachella Valley, California. Three laboratory studies were conducted to determine the utility of this method for control against Culex quinquefasciatus and Culex tarsalis : 1) efficacy evaluations of 2 formulations of ATSB, microencapsulated garlic oil, and a combination of microencapsulated garlic oil and 1% boric acid; 2) choice assays to determine the attractiveness of ATSB with the microencapsulated garlic oil against attractive sugar baits (ASB; the attractant alone; without toxin) and a 10% sucrose solution; and 3) vegetation efficacy tests on 3 common plant species in the Coachella Valley, Atriplex lentiformis, Tamarix ramosissima , and Pluchea sericea...

All animal membranes require cholesterol as an essential regulator of biophysical properties and function, but the levels of cholesterol vary widely among different subcellular compartments. Mitochondria, and in particular the inner mitochondrial membrane, have the lowest levels of cholesterol in the cell. Nevertheless, mitochondria need cholesterol for membrane maintenance and biogenesis, as well as oxysterol, steroid, and hepatic bile acid production. Alterations in mitochondrial cholesterol have been associated with a range of pathological conditions, including cancer, hepatosteatosis, cardiac ischemia, Alzheimer's, and Niemann-Pick Type C Disease...

BACKGROUND: Arthroscopic repair of large to massive rotator cuff tears commonly retear. To improve healing rates, a number of different approaches have been utilized, including the use of grafts, which may enhance the biomechanical and biologic aspects of the repair construct. However, the outcomes after the use of grafts are diverse. PURPOSE: To systematically review the literature for large to massive rotator cuff tears to determine whether the use of grafts generally provides superior tendon healing and clinical outcomes to the repairs without grafts...

BACKGROUND: After treatment for breast cancer, most women receive an annual surveillance mammography to look for subsequent breast cancers. Supplemental breast MRI is sometimes used in addition to mammography despite the lack of clinical evidence for it. Breast imaging after cancer treatment is an emotionally charged experience, an important part of survivorship care, and a topic about which limited patient information exists. We assessed women's experiences and preferences about breast cancer surveillance imaging with the goal of determining where gaps in care and knowledge could be filled...
