Gaining insight to pathologically relevant processes in continuous volumes of unstained brain tissue is important for a better understanding of neurological diseases. Many pathological processes in neurodegenerative disorders affect myelinated axons, which are a critical part of the neuronal circuitry. Cryo ptychographic X-ray computed tomography in the multi-keV energy range is an emerging technology providing phase contrast at high sensitivity, allowing label-free and non-destructive three dimensional imaging of large continuous volumes of tissue, currently spanning up to 400,000 μm3. This aspect makes the technique especially attractive for imaging complex biological material, especially neuronal tissues, in combination with downstream optical or electron microscopy techniques. A further advantage is that dehydration, additional contrast staining, and destructive sectioning/milling are not required for imaging. We have developed a pipeline for cryo ptychographic X-ray tomography of relatively large, hydrate used to guide further investigation of such swollen axons by correlative electron microscopy and immunogold labeling post X-ray imaging, a possibility demonstrated for the first time. Interestingly, we find that protein antigenicity and ultrastructure of the tissue are preserved after the X-ray measurement. As many pathological processes in neurodegeneration affect myelinated axons, our work sets an unprecedented foundation for studies addressing axonal integrity and disease-related changes in unstained brain tissues.
Attenuation correction using zero-echo time (ZTE) - magnetic resonance imaging (MRI) (ZTE-MRAC) has become one of the standard methods for brain-positron emission tomography (PET) on commercial PET/MR scanners. Although the accuracy of the net tracer-uptake quantification based on ZTE-MRAC has been validated, that of the diagnosis for dementia has not yet been clarified, especially in terms of automated statistical analysis. The aim of this study was to clarify the impact of ZTE-MRAC on the diagnosis of Alzheimer's disease (AD) by performing simulation study.

We recruited 27 subjects, who underwent both PET/computed tomography (CT) and PET/MR (GE SIGNA) examinations. Additionally, we extracted 107 subjects from the Alzheimer Disease Neuroimaging Initiative (ADNI) dataset. From the PET raw data acquired on PET/MR, three FDG-PET series were generated, using two vendor-provided MRAC methods (ZTE and Atlas) and CT-based AC. Following spatial normalization to Montreal Neurological Institute (MNI) space, we cal vs. 0.145 ± 0.122,
< 0.001). A higher correlation to the original PET score was observed in ZTE vs. O6-Benzylguanine purchase Atlas group (

0.982 vs. 0.961). The accuracy for the discrimination of AD patients from normal control was maintained in ZTE and Atlas compared to CTAC (ZTE vs. Atlas. vs. original; 82.5% vs. 82.1% vs. 83.2% (CI 81.8-84.5%), respectively).

For FDG-PET images on PET/MR, attenuation correction using ZTE-MRI had superior accuracy to an atlas-based method in classification for dementia. ZTE maintains the diagnostic accuracy for AD.

The COP has been postponed to 2021, but the pandemic did not stop the global civil society from "virtually" gathering to talk about the WHO FCTC, where it is and where it is going.''In the absence of the COVID-19 pandemic, many people in tobacco control worldwide would have been at the Hague, Netherlands, from 9-14 November for the 9th Conference of the Parties (COP9) of the WHO Framework Convention on Tobacco Control (FCTC), advocating for even stronger policies against the tobacco epidemic.

The environmental impact of a hurricane of this magnitude warrants careful assessment to devise preventive measures and mitigation strategies to bolster water resources management programs against future events. In this paper, we show the reconstructed simultaneous impacts of Hurricane Bob on the vegetative cover of the Mattapoisett river watershed and the water quality of the Mattapoisett Harbor with the aid of remote sensing for earth observations. The water quality impacts, especially in terms of Total Organic Carbon (TOC) and Sea Surface Salinity (SSS), can be identified from variations of SSS and TOC near coastal estuaries due to the influx of freshwater from the coastal Mattapoisett River to the continent-ocean transition between natural tides and bay waves. Using the Landsat satellite images, the Normalized Difference Vegetation Index (NDVI) and water quality constitutes (TOC and SSS) were reconstructed and retrieved for the assessment of the sea-land interactions during the Hurricane Bob event in 1991. Results indicate phenomenal interactive patterns between the harbor and the coastal watershed, as well as the riverine system. TOC and NDVI, especially in the upper watershed region, can be strongly correlated with hurricane impacts according to the singular value decomposition analysis.
The purpose of this article is to compare D. D. Palmer's hypothesis of tone with the modern hypothesis of biotensegrity.

Although researchers have been using the hypothesis of biotensegrity for over 40 years to explain the mechanics of movement within biological systems, it has experienced revived support in the last 25 years. Biotensegrity as a concept is applied at the molecular, cellular, tissue, and organ levels, revealing a different understanding of the architecture of biological organisms. Biotensegrity offers a way of exploring the human body in the field of functional anatomy. The model has become popular among bodywork and movement practitioners, as it recognizes the wholeness of the human body. D. D. Palmer used tone to explain the origin of disease; biotensegrity, instead, explains why certain diseases may develop.

The concept of tone hypothesized by D. D. Palmer is different from the modern concept of biotensegrity. Although biotensegrity offers a different way of seeing how the human body functions, using it as a theoretical framework to explain the effects of manual therapies such as chiropractic may be premature. The use of the biotensegrity hypothesis requires further research and investigation before application in clinical settings.

The purposes of this article are to describe the development of vitalism from its earliest Hellenistic form to that of a contemporary vitalism ethos and to propose the importance of vitalism in the philosophy of chiropractic and the chiropractic health care paradigm.

A review of the history of vitalism is offered to clarify the use of the term within the chiropractic literature and to provide a defensible position for vitalism as a foundation for future research in the philosophy of chiropractic. The founder of chiropractic, Daniel David Palmer, drew heavily from spiritualism and vitalism in his construction of early chiropractic philosophy. As chiropractic practice and philosophy have evolved, that vitalistic foundation has become a polemic used by factions within the profession, resulting in political challenges. The controversy within chiropractic mirrors similar debates within academic philosophy regarding vitalism. The philosophy of vitalism has developed beyond its classical constructs, emerging as erms.
The purpose of this article is to discuss evidence that supports the resolution of inequities for Medicare beneficiaries who receive chiropractic care.

Medicare covers necessary examinations, imaging, exercise instruction, and treatments for beneficiaries with back pain when provided by medical doctors, osteopaths, and their associated support staff such as nurse practitioners, physician assistants, clinical nurse specialists, and physical therapists. However, if the same patient with back pain presents to a chiropractor, then the only service that is covered by Medicare is manipulation of the spine. Current evidence does not support this inequity in Medicare beneficiary service coverage. There is no evidence to show an increase in serious risks associated with chiropractic treatment of neck or back pain in Medicare beneficiaries. Chiropractors support national public health goals and endorse safe, evidence-based practices. Chiropractic care for Medicare beneficiaries has been associated with enhanced cliut increasing program costs.
The current evidence suggests a need for change in US policy toward chiropractic in Medicare and support for HR 3654. Ending inequities by providing patients full coverage for chiropractic services has the potential to enhance care outcomes and reduce health disparities without increasing program costs.
The purpose of this article is to discuss exemplars of pro bono and charity activities in health care professions.

We searched PubMed and Google Scholar from inception to August 2019 using search terms "pro bono healthcare," "medical volunteerism," "pro bono clinics OR free clinics OR organizations," "pro bono curriculum OR education," "underserved OR uninsured OR underinsured OR disadvantaged OR poor populations." Inclusion criteria were that practitioners, students, or volunteers be involved in pro bono care or education and in any discipline, including medicine, physical therapy, chiropractic, or dentistry.

We selected 5 exemplars to review, and determined that students can benefit from participation in pro bono or charity health care such as through a student administered clinic model. Academic curricula can play a role in building confidence and create positive attitudes and behaviors regarding pro bono and charity activities, and nonprofit organizations can help build sustainable models.

We conclude that the implementation and delivery of health care pro bono or charity services can fill a health care gap and can be applied successfully in the health professions.
