Mitochondrial Donation in a Reproductive Care Pathway for mtDNA Disease.

Pathogenic variants in mitochondrial DNA (mtDNA) are a common cause of severe, often fatal, inherited metabolic disease. A reproductive care pathway was implemented to provide women carrying pathogenic mtDNA variants with reproductive options. A total of 22 women with pathogenic mtDNA variants have commenced or completed pronuclear transfer (and thus receipt of a mitochondrial donation), and there have been 8 live births.

Myco-Ed: Mycological curriculum for education and discovery.

Fungi are important and hyperdiverse organisms, yet chronically understudied. Most fungal clades have no reference genomes, impeding our understanding of their ecosystem functions and use as solutions in health and biotechnology. Also, opportunities for training in fungal biology and genomics are lacking, creating a bottleneck that hinders the recruitment and cultivation of a talented future mycological workforce.

Mitochondrial Donation and Preimplantation Genetic Testing for mtDNA Disease.

Background: Children born to women who carry pathogenic variants in mitochondrial DNA (mtDNA) are at risk for a range of clinical syndromes collectively known as mtDNA disease. Mitochondrial donation by pronuclear transfer involves transplantation of nuclear genome from a fertilized egg from the affected woman to an enucleated fertilized egg donated by an unaffected woman. Thus, pronuclear transfer offers affected women the potential to have a genetically related child with a reduced risk of mtDNA disease.

Transcriptome Analysis of Dryadomyces quercus-mongolicae, a Fungus Associated with Korean Oak Wilt Disease that Causes Oak Mortality in South Korea.

Korean oak wilt disease associated with Dryadomyces quercus-mongolicae recently emerged as a major tree disease in South Korea. A comprehensive transcriptome analysis is presented for D. quercus-mongolicae grown in vitro on three different culture media, identifying nearly 7,000 expressed transcripts.

seedling disease tolerance and vigor driven by breeding orchard size.

Gray (koa) is a Hawaiian endemic tree species that has a long history of use in the islands. In the late 20th century disease started impacting native koa stands, leading to the initiation of seed orchards that were founded from seeds collected across the islands. Large improvements in disease tolerance and vigor were achieved in very few cycles of selection despite the long temporal time of this perennial hardwood tree species.

Microsampling in toxicology studies - maximising the scientific, business and 3Rs advantages.

Adoption of a blood microsampling technique can reduce or avoid the use of satellite animals (rodents) for toxicokinetics or other purposes in discovery and toxicology studies and provides refinements applicable for both rodents and larger animals. Microsampling can increase the scientific value of data obtained from rodent studies during drug and (agro)chemical development, enabling multiple endpoints to be investigated and compared in an individual animal in the same way as non-rodents. A cross-sector survey was developed to understand the current use of microsampling in toxicology studies, with the aim of identifying the specific studies in which microsampling was employed and the barriers to wider uptake.

Protocol and Statistical Analysis Plan for the Randomized Trial of Sedative Choice for Intubation (RSI).

Background: Emergency tracheal intubation is a common and high-risk procedure. Ketamine and etomidate are sedative medicines commonly used to induce anesthesia for emergency tracheal intubation, but whether the induction medication used affects patient outcomes is uncertain.

Research Question: Does the use of ketamine for induction of anesthesia decrease the incidence of death among adults undergoing emergency tracheal intubation, compared to the use of etomidate?

Study Design And Methods: The Randomized trial of Sedative choice for Intubation (RSI) is a pragmatic, multicenter, unblinded, parallel-group, randomized trial being conducted in 14 sites (6 emergency departments and 8 intensive care units) in the United States.

Characterizing phenotype variants of Cercosporidium personatum, causal agent of peanut late leaf spot disease, their morphology, genetics and metabolites.

Cercosporidium personatum (CP) causes peanut late leaf spot (LLS) disease with 70% yield losses unless controlled by fungicides. CP grows slowly in culture, exhibiting variable phenotypes. To explain those variations, we analyzed the morphology, genomes, transcriptomes and chemical composition of three morphotypes, herein called RED, TAN, and BROWN.

Fire-associated microbial shifts in soils of western conifer forests with Armillaria root disease.

Unlabelled: Fires in coniferous forests throughout the northern United States alter ecosystem processes and ecological communities, including the diversity and composition of microbial communities living in the soil. In addition to its influence on ecosystem processes and functions, the soil microbiome can interact with soilborne pathogens to facilitate or suppress plant disease development. Altering the microbiome composition to promote taxa that inhibit pathogenic activity has been suggested as a management strategy for forest diseases, including Armillaria root disease caused by , which causes growth loss and mortality of conifers.

Patterns of occurrence, phenology, and phylogeny of Phloeosinus punctatus LeConte (Coleoptera: Curculionidae, Scolytinae) in giant sequoia.

Here, we describe patterns of reproduction and flight phenology of putative Phloeosinus punctatus in giant sequoia groves and compare morphology and genotypes of beetles from sympatric giant sequoia (Sequoiadendron giganteum) and California incense-cedar (Calocedrus decurrens). Surveys conducted in 2022 revealed that numerous branches fall from giant sequoia crowns (on average ~30 branches/tree), with 20%-50% of trees per site shedding branches, depositing breeding material for beetles on the forest floor that subsequently becomes colonized. When noninfested branches cut from mature giant sequoias were placed at the ground surface, they were colonized by P.

Assessing performance of simplified bioassays for soil-borne pathogens in smallholder systems of western Kenya.

Introduction: Soil-borne pathogens cause considerable crop losses and food insecurity in smallholder systems of sub-Saharan Africa. Soil and crop testing is critical for estimating pathogen inoculum levels and potential for disease development, understanding pathogen interactions with soil nutrient and water limitations, as well as for developing informed soil health and disease management decisions. However, formal laboratory analyses and diagnostic services for pathogens are often out of reach for smallholder farmers due to the high cost of testing and a lack of local laboratories.

Development and Evaluation of Real-Time Quantitative PCR Assays for Detection of Causing Brown Root Rot Disease.

Brown root rot disease (BRRD) is a highly destructive tree disease. Early diagnosis of BRRD has been challenging because the first symptoms and signs are often observed after extensive tissue colonization. Existing molecular detection methods, all based on the internal transcribed spacer (ITS) region, were developed without testing against global isolates, other wood-decay fungi, or host plant tissues.

Enhancing the provision of cancer nutrition information to support care through experience-based co-design: a mixed-methods study.

This study aimed to (1) investigate patient and carer access and perceptions, and health professional views and practices, relating to cancer nutrition information and care; and (2) co-design interactive resources to support optimal nutrition care.

Methods: Patients and carers completed a survey regarding access to nutrition care and information.

Population genomic analysis of an emerging pathogen Lonsdalea quercina affecting various species of oaks in western North America.

Understanding processes leading to disease emergence is important for effective disease management and prevention of future epidemics. Utilizing whole genome sequencing, we studied the phylogenetic relationship and diversity of two populations of the bacterial oak pathogen Lonsdalea quercina from western North America (Colorado and California) and compared these populations to other Lonsdalea species found worldwide. Phylogenetic analysis separated Colorado and California populations into two Lonsdalea clades, with genetic divergence near species boundaries, suggesting long isolation and populations that differ in genetic structure and distribution and possibly their polyphyletic origin.

The role of stress factors in severity of in greenhouse and field plantings of 13 peach () cultivars.

Understanding the host-pathogen-environmental interactions in a pathosystem is essential for management of diseases and diminished crop yields. Abiotic stressors such as cold damage, water deficit, and high pH soils can be major limiting factors to tree fruit production. Along with decreased yields, these abiotic factors can have direct implications for disease severity within orchards.
