Blending Indigenous and western science: Quantifying cultural burning impacts in Karuk Aboriginal Territory.

The combined effects of Indigenous fire stewardship and lightning ignitions shaped historical fire regimes, landscape patterns, and available resources in many ecosystems globally. The resulting fire regimes created complex fire-vegetation dynamics that were further influenced by biophysical setting, disturbance history, and climate. While there is increasing recognition of Indigenous fire stewardship among western scientists and managers, the extent and purpose of cultural burning is generally absent from the landscape-fire modeling literature and our understanding of ecosystem processes and development.

Biofilm formation and desiccation survival of Listeria monocytogenes with microbiota on mushroom processing surfaces and the effect of cleaning and disinfection.

Microbial multispecies communities consisting of background microbiota and Listeria monocytogenes could be established on materials used in food processing environments. The presence, abundance and diversity of the strains within these microbial multispecies communities may be affected by mutual interactions and differences in resistance towards regular cleaning and disinfection (C&D) procedures. Therefore, this study aimed to characterize the growth and diversity of a L.

Enhancing Indigenous Food Sovereignty and Community Health Through the Karuk Agroecosystem Resilience Initiative: We Are Caring for It: xúus nu'éethti.

Indigenous communities in the United States experience some of the highest rates of food insecurity and diet-related diseases despite an abundance of food assistance programs and other public health interventions. New approaches that center Indigenous perspectives and solutions are emerging and urgently needed to better understand and address these challenges. This Practice Note shares lessons learned from ongoing collaboration between the Karuk Tribe and University of California, Berkeley researchers and other partners to assess and enhance food sovereignty among Tribes and Tribal communities in the Klamath River Basin.

Growth performance of Listeria monocytogenes and background microbiota from mushroom processing environments.

Interaction between Listeria monocytogenes and resident background microbiota may occur in food processing environments and may influence the survival of this pathogen in a factory environment. Therefore the aim of this study was to characterize the growth performance of microbiota isolated from the processing environments of frozen sliced mushrooms, and to investigate the competitive performance of L. monocytogenes when co-cultured with accompanying environmental microbiota.

Variability in growth and biofilm formation of Listeria monocytogenes in Agaricus bisporus mushroom products.

Foods and food production environments can be contaminated with Listeria monocytogenes and may support growth of this foodborne pathogen. This study aims to characterize the growth and biofilm formation of sixteen L. monocytogenes strains, isolated from mushroom production and processing environments, in filter-sterilized mushroom medium.

Subcutaneous sarcoidosis (Darier-Roussy sarcoidosis) with extensive disease on positron emission tomography: A case report and review of the literature.

Cutaneous manifestations of sarcoidosis are common, but subcutaneous nodules are rare, originally described in 1904 by Darier and Roussy and thought to represent isolated skin disease. We present a 61-year-old male who presented with 3 months of subcutaneous nodules on the forearms and knees. Biopsy confirmed sarcoidosis.

Genomic characteristics of Listeria monocytogenes isolated during mushroom (Agaricus bisporus) production and processing.

Listeria monocytogenes is a foodborne pathogen ubiquitously found in nature and which has been isolated from food and food processing environments. This study aimed to characterize L. monocytogenes strains isolated from the production and processing environments of frozen sliced mushrooms (Agaricus bisporus).

Adapting western North American forests to climate change and wildfires: 10 common questions.

We review science-based adaptation strategies for western North American (wNA) forests that include restoring active fire regimes and fostering resilient structure and composition of forested landscapes. As part of the review, we address common questions associated with climate adaptation and realignment treatments that run counter to a broad consensus in the literature. These include the following: (1) Are the effects of fire exclusion overstated? If so, are treatments unwarranted and even counterproductive? (2) Is forest thinning alone sufficient to mitigate wildfire hazard? (3) Can forest thinning and prescribed burning solve the problem? (4) Should active forest management, including forest thinning, be concentrated in the wildland urban interface (WUI)? (5) Can wildfires on their own do the work of fuel treatments? (6) Is the primary objective of fuel reduction treatments to assist in future firefighting response and containment? (7) Do fuel treatments work under extreme fire weather? (8) Is the scale of the problem too great? Can we ever catch up? (9) Will planting more trees mitigate climate change in wNA forests? And (10) is post-fire management needed or even ecologically justified? Based on our review of the scientific evidence, a range of proactive management actions are justified and necessary to keep pace with changing climatic and wildfire regimes and declining forest heterogeneity after severe wildfires.

Wildfire and climate change adaptation of western North American forests: a case for intentional management.

Forest landscapes across western North America (wNA) have experienced extensive changes over the last two centuries, while climatic warming has become a global reality over the last four decades. Resulting interactions between historical increases in forested area and density and recent rapid warming, increasing insect mortality, and wildfire burned areas, are now leading to substantial abrupt landscape alterations. These outcomes are forcing forest planners and managers to identify strategies that can modify future outcomes that are ecologically and/or socially undesirable.

Mass spectrometry: an old dog with new tricks.

We take a look at how this 100-year-old technique is shedding new light on protein-protein interactions.

Inside the brain of a killer: the ethics of neuroimaging in a criminal conviction.

With neuroimaging techniques being taken out of the lab and into the court, we ask whether brain scans can - or should - be used to explain a criminal act.

Fire and biodiversity in the Anthropocene.

Fire has been a source of global biodiversity for millions of years. However, interactions with anthropogenic drivers such as climate change, land use, and invasive species are changing the nature of fire activity and its impacts. We review how such changes are threatening species with extinction and transforming terrestrial ecosystems.

Understanding cough in interstitial lung disease: a cross-sectional study on the adequacy of treatment.

Background: Cough is a common symptom in interstitial lung disease (ILD), often leading to treatment dissatisfaction for patients and physicians.

Aim: To identify the prevalence and subjective adequacy of control of cough in patients with ILD.

Methods: A cross-sectional study of patients with ILD attending a tertiary ILD clinic in Perth was undertaken using a pre-designed questionnaire that patients were invited to complete when attending clinic.

Idiopathic and immune-related pulmonary fibrosis: diagnostic and therapeutic challenges.

Interstitial lung disease (ILD) encompasses a large group of pulmonary conditions sharing common clinical, radiological and histopathological features as a consequence of fibrosis of the lung interstitium. The majority of ILDs are idiopathic in nature with possible genetic predisposition, but is also well recognised as a complication of connective tissue disease or with certain environmental, occupational or drug exposures. In recent years, a concerted international effort has been made to standardise the diagnostic criteria in ILD subtypes, formalise multidisciplinary pathways and standardise treatment recommendations.
