Thermal tolerance data are important for identifying the potential range of non-native species following introduction and establishment. Such data are particularly important for understanding invasion risks of tropical species introduced to temperate climates and identifying whether they can survive outside tropical regions. A breeding population of the tropical clawed frog (Xenopus tropicalis) was recently discovered in west-central Florida, U.

Monitoring space radiation is of vital importance for risk reduction strategies in human space exploration. Radiation protection programs on Earth and in space rely on personal and area radiation monitoring instruments. Crew worn radiation detectors are crucial for successful crew radiation protection programs since they measure what each crewmember experiences in different shielding configurations within the space habitable volume.

While biotic-abiotic interactions are increasingly documented in nature, a process-based understanding of how such interactions influence community assembly is lacking in the ecological literature. Perhaps the most emblematic and pervasive example of such interactions is the synergistic threat to biodiversity posed by climate change and invasive species. Invasive species often out-compete or prey on native species.

Because individuals with HIV are living longer, comorbidities are moving to the forefront of HIV patient care. People with HIV have a higher risk for HIV-related and non-HIV-related cancers than the general population, making cancer screening vital for this population. Immunizations are another important element of primary care for older adults with HIV, including a COVID-19 vaccine, about which data continue to evolve.

Background: The taxonomic classification of Cannabis genus has been delineated through three main types: sativa (tall and less branched plant with long and narrow leaves), indica (short and highly branched plant with broader leaves) and ruderalis (heirloom type with short stature, less branching and small thick leaves). While still under discussion, particularly whether the genus is polytypic or monotypic, this broad classification reflects putative geographical origins of each group and putative chemotype and pharmacologic effect.

Methods: Here we describe a thorough investigation of cannabis accessions using a set of 23 highly informative and polymorphic SNP (Single Nucleotide Polymorphism) markers associated with important traits such as cannabinoid and terpenoid expression as well as fibre and resin production.

Aims: Direct acting antiviral (DAA) hepatitis C (HCV) medications are funded in New Zealand since 2016 for some and since 2019 for all genotypes. The purpose of this study was to review New Zealand-wide data of the use of generic HCV DAA medications imported through Tasmanian FixHepC Buyer's Club and the associated side effect profiles.

Methods: This is a retrospective data audit on the use of generic DAAs to treat HCV; outcomes from consecutive hepatitis C patients (naïve and pre-treated) treated with generic DAAs (sofosbuvir/ledipasvir, sofosbuvir/daclatasvir, sofosbuvir/ledipasvir, ribavirin) collected from all known sites that used Buyer's club medications in eight New Zealand district health board regions were summarised.

Use of electronic health record data is expanding to support quality improvement and research; however, this requires standardization of the data and validation within and across organizations. Information models (IMs) are created to standardize data elements into a logical organization that includes data elements, definitions, data types, values, and relationships. To be generalizable, these models need to be validated across organizations.

Medical cannabis patients receive clinical benefits from the secondary metabolites of the plant, which contain a variety of cannabinoids and terpenoids in combinations that can be used to classify the chemovars. State-regulated medical cannabis programs rely on breeder-reported "strain" names both within diversion control systems and to describe the medical cannabis products that are sold to patients in medical cannabis dispensaries. In state-regulated medical cannabis programs, there is no conventional nomenclature system that correlates the breeder-reported names with their profiles of active ingredients, and these "strain" names are invalid as they refer to chemical differences properly referred to as to chemovars.

Introduction: The recent lowering of the World Health Organisation (WHO) haemoglobin (Hb) and haematocrit (HCT) thresholds for diagnosis of polycythaemia vera (PV) has markedly increased the proportion of complete blood counts (CBC) that could be referred for haematologist review for comment, including advice on JAK2 V617F mutation analysis. The utility of an algorithm based on CBC indices and immature platelet fraction (IPF) to select cases for haematologist review was investigated.

Methods: IPF analysis was performed on 22 patients with known JAK2 V617F mutation and 41 patients who were negative for this mutation previously tested because of suspicion of PV.
