Waimānalo Pono Research Hui: A Community-Academic Partnership to Promote Native Hawaiian Wellness through Culturally Grounded and Community-Driven Research and Programming.

Although Hawai'i is often portrayed as an idyllic paradise and is recognized as one of the healthiest States in the United States, pervasive health disparities exist among Native Hawaiians. Similar to other indigenous populations across the globe, these disparities are linked to unjust social and economic policies rooted in colonization and historical trauma. Western-centric efforts to address these disparities have yielded limited results. Consequently, indigenous frameworks to decolonize western-centric r...


Ambivalence towards discourse of disaster resilience.

This paper investigates empirically how the international aid community (IAC)-donors and practitioners-considers and implements disaster resilience in a specific country setting, Nepal, and throughout the rest of the world. A key finding is that there is ambivalence about a concept that has become a discourse. On a global level, the IAC utilises the discourse of resilience in a cautiously positive manner as a bridging concept. On a national level, it is being used to influence the Government of Nepal, as we...

The interindividual variability of transcranial magnetic stimulation effects: Implications for diagnostic use in movement disorders.

A large number of methods have been described that use transcranial magnetic stimulation to probe the physiology of the human motor cortex. Since the 1990s, hundreds of papers have used them to investigate neurophysiological signatures of different types of movement disorders. However, in recent years there has been increasing recognition of the interindividual variability of these measures and a focus on estimating their reliability and reproducibility. Although this work has been carried out in healthy in...


Poor survival of dialysis patients with unhealed wounds because of critical limb ischemia: Limb salvage and survival requires wound healing.

Maintenance of blood flow in the wound area is required to heal wounds of critical limb ischemia (CLI) in dialysis patients. However, many dialysis patients have both a stenotic lesion in below-knee blood vessels and a cardiovascular event as complications, and thus, it may be difficult to ensure sufficient blood flow. Therefore, many deaths occur because of problems with wound healing. The aim of this study is to identify the optimal treatment, including revascularisation and amputation, from the perspecti...

Strategies to Counteract Botulinum Neurotoxin A: Nature's Deadliest Biomolecule.

Botulinum neurotoxin serotype A (BoNT/A), marketed commercially as Botox, is the most toxic substance known to man with an estimated intravenous lethal dose (LD) of 1-2 ng/kg in humans. Despite its widespread use in cosmetic and medicinal applications, no postexposure therapeutics are available for the reversal of intoxication in the event of medical malpractice or bioterrorism. Accordingly, the Centers for Disease Control and Prevention categorizes BoNT/A as a Category A pathogen, posing the highest risk t...

Structural and Functional Characterization of YdjI, an Aldolase of Unknown Specificity in Escherichia coli K12.

The ydj gene cluster is found in 80% of sequenced Escherichia coli genomes and other closely related species found in the human microbiome. Based on the annotations of the enzymes located in this cluster, it is expected that together they catalyze the catabolism of an unknown carbohydrate. The focus of this investigation is on YdjI, which is found in the ydj gene cluster of E. coli K-12. It is predicted to be a class II aldolase of unknown function. Here we describe a structural and functional characterizat...

Opportunities and challenges using non-targeted methods for food fraud detection.

In recent years, non-targeted methods have been a popular "buzz" phrase in food fraud detection. Using analytical instrumentation techniques, non-targeted methods have been developed and applied in many food and agricultural situations. However, confusion and misstatements remain regarding how the methods are used. This perspective will discuss the definitions related to non-targeted testing, the procedure of developing and validating methods, the techniques and data analysis, and opportunities and challeng...

Synthesis and structural characterization of a ubiquitous transformation product of fungicide prochloraz (BTS 40348).

Prochloraz is a widely used imidazole fungicide that has to be analyzed together with its metabolites or transformation products for food safety monitoring purposes in the European Union. Although the focus in food of plant origin has been set on metabolites BTS 44595 and BTS 44596, we consider relevant the study of BTS 40348 metabolite too, since it has been detected in both raw and processed foods based on citrus fruits in the EU. Metabolite BTS 40348 should be monitored in surface water due to its ecotox...

Interactive Toxicity of Triclosan and Nano-TiO2 to Green Alga Eremosphaera viridis in Lake Erie: A New Perspective based on Fourier Transform Infrared Spectromicroscopy and Synchrotron-based X-ray Fluorescence Imaging.

This study explored the toxicity of triclosan in the presence of TiO2 P25 to the green alga Eremosphaera viridis in Lake Erie. Multiple physicochemical endpoints were conducted to perform a comprehensive analysis of the toxic effects of individual and combined pollutants. Fourier transform infrared spectromicroscopy and synchrotron-based X-ray fluorescence imaging were first documented to be applied to explore the distribution variation of macromolecules and microelements in single algal cells in interactiv...

Artificial intelligence for precision education in radiology.

In the era of personalized medicine, the emphasis of health care is shifting from populations to individuals. Artificial intelligence (AI) is capable of learning without explicit instruction and has emerging applications in radiology. Whereas much attention has focused on teaching radiology trainees about AI, here our goal is to instead focus on how AI might be developed to better teach radiology trainees. While the idea of using AI to improve education is not new, the application of AI to medical and radio...

Spinal metastasis: Diagnosis, Management and Follow-up.

Spine metastatic disease is an increasingly common occurrence in cancer patients due to improved patient survival. Close proximity of the bony spinal column to the spinal cord limits many conventional treatments for metastatic disease. In the past decade, we have witnessed dramatic advancements in therapies, with improvements in surgical techniques and recent adoption of spine stereotactic radiotherapy techniques leading to improved patient outcomes. Multi disciplinary approaches to patient evaluation, trea...

What Is the Best Method to Differentiate Acute Charcot Foot From Acute Infection?

Differentiation between acute Charcot neuroarthropathy (CN) and acute infection/osteomyelitis is complex and requires multiple (>1) diagnostic criteria. These criteria include an emphasis on the presence of neuropathy, history, and physical examination. The absence of skin wounds and resolution of swelling/erythema with elevation makes the likelihood of infection very low. In unclear cases, laboratory testing, histologic examination and culturing of bone specimens, scintigraphy, and imaging, especially magn...

A New Plea to Focus on the End-of-Life Needs of People with Severe Mental Illnesses.

Structural basis for recognition of the tumor suppressor protein PTPN14 by the oncoprotein E7 of human papillomavirus.

Human papillomaviruses (HPVs) are causative agents of various diseases associated with cellular hyperproliferation, including cervical cancer, one of the most prevalent tumors in women. E7 is one of the two HPV-encoded oncoproteins and directs recruitment and subsequent degradation of tumor-suppressive proteins such as retinoblastoma protein (pRb) via its LxCxE motif. E7 also triggers tumorigenesis in a pRb-independent pathway through its C-terminal domain, which has yet been largely undetermined, with a la...

Seasonality of influenza and its association with meteorological parameters in two cities of Pakistan: A time series analysis.

Influenza is known to have a specific pattern of seasonality the reasons for which are yet to be fully ascertained. Temperate zones show influenza epidemic during the winter months. The tropical and subtropical regions show more diverse influenza outbreak patterns. This study explores the seasonality of influenza activity and predicts influenza peak based on historical surveillance time series data in Islamabad and Multan, Pakistan.

Recombinant vector vaccine evolution.

Replicating recombinant vector vaccines consist of a fully competent viral vector backbone engineered to express an antigen from a foreign transgene. From the perspective of viral replication, the transgene is not only dispensable but may even be detrimental. Thus vaccine revertants that delete or inactivate the transgene may evolve to dominate the vaccine virus population both during the process of manufacture of the vaccine as well as during the course of host infection. A particular concern is that this ...

Hidden diversity in waterfall environments: The genus Acrorbis (Gastropoda: Planorbidae) from the Upper-Paraná Atlantic Forest.

High-energy freshwater environments such as rapids and waterfalls in the Upper-Paraná Atlantic Forest are home to highly endemic minute freshwater snails of the genus Acrorbis. Only one species, Acrorbis petricola, is currently included within this genus, whose geographical distribution is restricted to three known populations, one in Brazil and the other two in Argentina. Because of habitat specificity and limited geographical distribution, the species is considered vulnerable in Argentina and endangered ...

Acceptable outcomes after fundoplication-different views are held by patients, GPs, and surgeons.

Antireflux surgery aims to improve quality of life. However, whether patients and clinicians agree on what this means, and what is an acceptable outcome following fundoplication, is unknown. This study used clinical scenarios pertinent to laparoscopic fundoplication for gastroesophageal reflux to define acceptable outcomes from the perspective of patients, surgeons, and general practitioners (GPs). Patients who had previously undergone a laparoscopic fundoplication, general practitioners, and esophagogastri...

Visual working memory representation as a topological defined perceptual object.

The question of what the basic unit is of visual working memory remains one of the most fundamental and controversial issues. In the current study, we proposed a unique perspective based on early topological perception to describe the nature of representation in visual working memory. In a series of updating change-detection tasks, the repetition-benefit effect on color memory was not affected when items in the second memory array underwent massive changes of nontopological features from the first memory ar...

Giant Cell Tumor of Soft Tissue: A Rare Entity.

Giant cell tumor (GCT) of the soft tissue (GCT-ST) is a rare, unusual primary soft tissue tumor that is completely distinct from, and should not be confused with, any giant cell-rich tumor of bone or soft tissue. Currently, GCT-ST is included in the group of so-called fibrohistiocytic tumors of intermediate (borderline) malignancy. The most common symptom is a painless, slow-growing mass in a superficial location. Computed tomography and magnetic resonance imaging show a solid, nonhomogeneous, frequently he...

Unprecedented herbivory threatens rear-edge populations of Betula in southwestern Eurasia.

Mediterranean rear-edge populations of Betula, located at the southwestern Eurasian margin of the distribution range, represent unique reservoirs of genetic diversity. However, increasing densities of wild ungulates, enhanced dryness, and wildfires threaten their future persistence. A historical perspective on the past responses of these relict populations to changing herbivory, fire occurrence and climatic conditions may contribute to assessing their future responses under comparable scenarios. We have rec...

Plants alter their vertical root distribution rather than biomass allocation in response to changing precipitation.

Elucidating the variation of allocation pattern of ecosystem net primary productivity (NPP) and its underlying mechanisms are critically important for understanding the changes of aboveground and belowground ecosystem functions. Under optimal partitioning theory, plants should allocate more NPP to the organ that acquires the most limiting resource, and this expectation has been widely used to explain and predict NPP allocation under changing precipitation. However, confirmatory evidence for this theory has ...

microclimUS: hourly estimates of historical microclimates for the United States of America with example applications.

Microclimatic data is required for many problems in pure and applied ecology. This data includes above-ground convective and radiative conditions as well as soil temperature and moisture. In cold regions, the connection between above- and below-ground microclimates via snow cover is also critically important. Here I describe a data set of hourly microclimates for continental USA, simulated from the years 1979 to 2017 across a grid of 2287 locations approximately 60 km apart. The data were generated with the...

It was organized by Professor Haruhiro Inoue of Showa University Koto Toyosu Hospital, Japan, who established the peroral endoscopic mytomy (POEM) technique. Given its focus on reflecting on the international performance of Professor Inoue, the meeting was very international in character, and many overseas researchers were invited to the meeting, with some sessions held e...

Chronically stimulated human MAIT cells are unexpectedly potent IL-13 producers.

Mucosal-associated invariant T (MAIT) cells are unconventional T cells that recognize antigens derived from riboflavin biosynthesis. In addition to anti-microbial functions, human MAIT cells are associated with cancers, autoimmunity, allergies and inflammatory disorders, although their role is poorly understood. Activated MAIT cells are well known for their rapid release of Th1 and Th17 cytokines, but we have discovered that chronic stimulation can also lead to potent interleukin (IL)-13 expression. We used...
