Thermotolerant coral-algal mutualisms maintain high rates of nutrient transfer while exposed to heat stress.

Symbiotic mutualisms are essential to ecosystems and numerous species across the tree of life. For reef-building corals, the benefits of their association with endosymbiotic dinoflagellates differ within and across taxa, and nutrient exchange between these partners is influenced by environmental conditions. Furthermore, it is widely assumed that corals associated with symbionts in the genus tolerate high thermal stress at the expense of lower nutrient exchange to support coral growth.

Different functional traits among closely related algal symbionts dictate stress endurance for vital Indo-Pacific reef-building corals.

Reef-building corals in the genus Porites are one of the most important constituents of Indo-Pacific reefs. Many species within this genus tolerate abnormally warm water and exhibit high specificity for particular kinds of endosymbiotic dinoflagellates that cope with thermal stress better than those living in other corals. Still, during extreme ocean heating, some Porites exhibit differences in their stress tolerance.

Mutualistic microalgae co-diversify with reef corals that acquire symbionts during egg development.

The application of molecular genetics has reinvigorated and improved how species are defined and investigated scientifically, especially for morphologically cryptic micro-organisms. Here we show how species recognition improves understanding of the ecology and evolution of mutualisms between reef-building corals and their mutualistic dinoflagellates (i.e.

Cladocopium community divergence in two Acropora coral hosts across multiple spatial scales.

Many broadly-dispersing corals acquire their algal symbionts (Symbiodiniaceae) "horizontally" from their environment upon recruitment. Horizontal transmission could promote coral fitness across diverse environments provided that corals can associate with divergent algae across their range and that these symbionts exhibit reduced dispersal potential. Here we quantified community divergence of Cladocopium algal symbionts in two coral host species (Acropora hyacinthus, Acropora digitifera) across two spatial scales (reefs on the same island, and between islands) across the Micronesian archipelago using microsatellites.

Splicing profile by capture RNA-seq identifies pathogenic germline variants in tumor suppressor genes.

Germline variants in tumor suppressor genes (TSGs) can result in RNA mis-splicing and predisposition to cancer. However, identification of variants that impact splicing remains a challenge, contributing to a substantial proportion of patients with suspected hereditary cancer syndromes remaining without a molecular diagnosis. To address this, we used capture RNA-sequencing (RNA-seq) to generate a splicing profile of 18 TSGs (, , , , , , , , , , , , , , , , , and ) in 345 whole-blood samples from healthy donors.

Unsupervised machine learning reveals mimicry complexes in bumblebees occur along a perceptual continuum.

Müllerian mimicry theory states that frequency-dependent selection should favour geographical convergence of harmful species onto a shared colour pattern. As such, mimetic patterns are commonly circumscribed into discrete mimicry complexes, each containing a predominant phenotype. Outside a few examples in butterflies, the location of transition zones between mimicry complexes and the factors driving mimicry zones has rarely been examined.

Coordinating an Oncology Precision Medicine Clinic Within an Integrated Health System: Lessons Learned in Year One.

Precision medicine is a term describing strategies to promote health and prevent and treat disease based on an individual's genetic, molecular, and lifestyle characteristics. Oncology precision medicine (OPM) is a cancer treatment approach targeting cancer-specific genetic and molecular alterations. Implementation of an OPM clinical program optimally involves the support and collaboration of multiple departments, including administration, medical oncology, pathology, interventional radiology, genetics, research, and informatics.

Host-symbiont combinations dictate the photo-physiological response of reef-building corals to thermal stress.

High sea surface temperatures often lead to coral bleaching wherein reef-building corals lose significant numbers of their endosymbiotic dinoflagellates (Symbiodiniaceae). These increasingly frequent bleaching events often result in large scale coral mortality, thereby devasting reef systems throughout the world. The reef habitats surrounding Palau are ideal for investigating coral responses to climate perturbation, where many inshore bays are subject to higher water temperature as compared with offshore barrier reefs.

Population Connectivity in the Common Reef Zoantharian Zoanthus sansibaricus (Anthozoa: Hexacorallia) in Southern Japan.

Tropical and subtropical shallow benthic marine communities are highly diverse and balanced systems that constitute an important natural resource. Knowledge of the genetic diversity, connectivity and reproduction mode of each population is critical to understanding the fate of whole assemblages in times of disturbances. Importantly, the capability of populations to adapt to environmental challenges will be crucial to determining their survival.

Implementing a Virtual Health Telemedicine Program in a Community Setting.

Aurora Health Care in eastern Wisconsin has a clinical genetics program driven by genetic counselors in the cancer/adult and prenatal genetics settings. In 2015, the workforce shortage of genetic counselors left us with 4 open positions for genetic counselors that we were unable to fill. We explored many models of alternative service delivery, and determined virtual health (VH) via telemedicine to be the best option for our system.

Adrenocortical carcinoma and succinate dehydrogenase gene mutations: an observational case series.

Objective: Germline loss-of-function mutations in succinate dehydrogenase () genes results in rare tumor syndromes that include pheochromocytoma, paraganglioma, and others. Here we report a case series of patients with adrenocortical carcinoma (ACC) that harbor mutations.

Patients And Results: We report four unrelated patients with ACC and mutations.

Population genetics of reef coral endosymbionts (Symbiodinium, Dinophyceae).

Symbiodinium is a diverse genus of unicellular dinoflagellate symbionts associating with various marine protists and invertebrates. Although the broadscale diversity and phylogenetics of the Symbiodinium complex is well established, there have been surprisingly few data on fine-scale population structure and biogeography of these dinoflagellates. Yet population-level processes contribute strongly to the biology of Symbiodinium, including how anthropogenic-driven global climate change impacts these symbionts and their host associations.

Symbiodinium population genetics: testing for species boundaries and analysing samples with mixed genotypes.

Population genetic markers are increasingly being used to study the diversity, ecology and evolution of Symbiodinium, a group of eukaryotic microbes that are often mutualistic with reef-building corals. Population genetic markers can resolve individual clones, or strains, from samples of host tissue; however, samples may comprise different species that may confound interpretations of gene flow and genetic structure. Here, we propose a method for resolving species from population genetic data using tests for genetic recombination.

Most Low-Abundance "Background" Symbiodinium spp. Are Transitory and Have Minimal Functional Significance for Symbiotic Corals.

Speculation surrounds the importance of ecologically cryptic Symbiodinium spp. (dinoflagellates) that occur at low abundances in reef-building corals and in the surrounding environment. Evidence acquired from extensive sampling, long-term monitoring, and experimental manipulation can allow us to deduce the ecology and functional significance of these populations and whether they might contribute to the response of coral-dinoflagellate mutualisms to climate change.

Microbial invasion of the Caribbean by an Indo-Pacific coral zooxanthella.

Human-induced environmental changes have ushered in the rapid decline of coral reef ecosystems, particularly by disrupting the symbioses between reef-building corals and their photosymbionts. However, escalating stressful conditions enable some symbionts to thrive as opportunists. We present evidence that a stress-tolerant "zooxanthella" from the Indo-Pacific Ocean, Symbiodinium trenchii, has rapidly spread to coral communities across the Greater Caribbean.

Promising outcomes of screening for pancreatic cancer by genetic testing and endoscopic ultrasound.

Objective: This study aimed to determine if screening patients based on certain cancer syndromes or family history criteria can lead to early detection of pancreatic cancer.

Methods: This was a cohort study from 2008 to 2011 at a large tertiary referral center. A total of 30 patients met high-risk criteria after genetic counseling and were referred to a gastroenterologist for possible endoscopic ultrasound (EUS).

Host-specialist lineages dominate the adaptive radiation of reef coral endosymbionts.

Bursts in species diversification are well documented among animals and plants, yet few studies have assessed recent adaptive radiations of eukaryotic microbes. Consequently, we examined the radiation of the most ecologically dominant group of endosymbiotic dinoflagellates found in reef-building corals, Symbiodinium Clade C, using nuclear ribosomal (ITS2), chloroplast (psbA(ncr)), and multilocus microsatellite genotyping. Through a hierarchical analysis of high-resolution genetic data, we assessed whether ecologically distinct Symbiodinium, differentiated by seemingly equivocal rDNA sequence differences, are independent species lineages.

Genotypic diversity and spatial-temporal distribution of Symbiodinium clones in an abundant reef coral.

Genetic data are rapidly advancing our understanding of various biological systems including the ecology and evolution of coral-algal symbioses. The fine-scale interactions between individual genotypes of host and symbiont remain largely unstudied and constitute a major gap in knowledge. By applying microsatellite markers developed for both host and symbiont, we investigated the intracolony diversity, prevalence and stability of Symbiodinium glynni (type D1) multilocus genotypes in association with dense populations of Pocillopora at two sites in the Gulf of California.

Implementation of a standard pharmacy clinical practice model in a multihospital system.

Purpose: The implementation of a standard pharmacy clinical practice model in a multihospital health system is described.

Summary: An initiative to enhance the quality and scope of pharmacy clinical practices by transitioning from a pharmacy practice model focused on order entry and distributive functions to a patient-centered model focused on drug therapy management and documentation was begun within the Providence Health and Services System. After demonstrating favorable results during pilot testing in the system's largest hospital, the pharmacy practice model was implemented at two facilities, which took approximately six months.

Assessment of clinical practices among cancer genetic counselors.

Various models of cancer genetics service delivery have been published, and practice guidelines were set forth by the National Society of Genetic Counselors (NSGC) in 2004. While the demand for services has increased, there has not been a comprehensive study of current practice models. An online survey of the NSGC Familial Cancer Risk Counseling Special Interest Group was conducted to study current methods of providing clinical cancer genetics services.
