This study examines the perceptual basis of diagnostic virtuosity in East Asian medicine, combining Merleau-Ponty's phenomenology and an ethnographic investigation of Korean medicine in South Korea. A novice, being exposed to numerous clinical transactions during apprenticeship, organizes perceptual experience that occurs between him or herself and patients. In the process, the fledgling practitioner's body begins to set up a medically-tinged "intentionality" interconnecting his or her consciousness and medically significant qualities in patients...

Open surgery and arthroscopy for the treatment of synovial chondromatosis (SC) of the temporomandibular joint (TMJ) have their advantages and disadvantages. The aim of this study was to report the application and results of the combined use of these two methods in the treatment of SC and the indications for use. A total of 36 patients with magnetic resonance imaging (MRI) confirmation of SC, treated from 2010 to 2015, were included. Patients with tumours in the upper articular cavity and with the extended margin of the medial groove still in-between the medial crest of the condyle and infratemporal space on coronal MRI were selected to undergo open surgery with the assistance of arthroscopy to clear the loose bodies and affected synovium...

Cryptococcosis is a fungal infection caused by Cryptococcus spp. that enters the body via inhalation. This ubiquitous yeast has gained notoriety as an opportunistic pathogen in the immunosuppressed population. The authors report a case of a previously-well adult male presented with left-sided weakness. Imaging demonstrated a pulmonary mass and 2 contrast-enhancing intracranial lesions-all features suggestive of a primary lung carcinoma with brain metastases. However, further investigations confirmed disseminated cryptococcosis, without evidence of malignancy...

In the practice of in vivo imaging with carbon nanodots (CNDs) as probe, the volume of CNDs solution introduced into living body should be kept at minimum, and a higher concentration is needed to ensure sufficient quantity of the probe for obtaining bright image. Therefore, the improvement on biocompatibility of the CNDs is among the most important and critical issues. We report herein the improvement on the biocompatibility of CNDs with modification by ionic liquid. Amide group functionalization of carbon nanodots is first conducted through microwave irradiation, followed by coupling the ionic liquid 1-carboxymethyl-3-methyl imidazolium bromide on the surface of the Amide-CNDs via covalent conjunction to produce the modified carbon nanodots (IL-CNDs)...

Human dopaminergic system in general, and substantia nigra (SN) neurons, in particular, are implicated in the pathologies underlying the human brain aging. The interplay between aberrations in the structural organization and elemental composition of SN neuron bodies has recently gained in importance as selected metals: Fe, Cu, Zn, Ca were found to trigger oxidative-stress-mediated aberration in their molecular assembly due to concomitant protein (alpha-synuclein, tau-protein) aggregation, gliosis and finally oxidative stress...

Lung cancer has the highest mortality rate among cancer patients in the world, in particular because most patients are only diagnosed at an advanced and non-curable stage. Computed tomography (CT) screening on high-risk individuals has shown that early detection could reduce the mortality rate. However, the still high false-positive rate of CT screening may harm healthy individuals because of unnecessary follow-up scans and invasive follow-up procedures. Alternatively, false-negative and indeterminate results may harm patients due to the delayed diagnosis and treatment of lung cancer...

The present work introduces deliberate synthesis of Gd(III)-doped silica nanoparticles with high relaxivity at magnetic field strengths below 1.5T. Modified microemulsion water-in-oil procedure was used in order to achieve superficial localization of Gd(III) complexes within 40-55nm sized silica spheres. The relaxivities of the prepared nanoparticles were measured at 0.47, 1.41 and 1.5T with the use of both NMR analyzer and whole body NMR scanner. Longitudinal relaxivities of the obtained silica nanoparticles reveal significant dependence on the confinement mode, changing from 4...

PURPOSE: Indices from 3-D ultrasound may have a role in developmental dysplasia of the hip (DDH) assessment, but require a way to determine spatial orientation relative to body axes. The lateral iliac wall angle is a potentially suitable reference axis in 3-D ultrasound. We sought to quantify normal values and variations of the infant iliac wall angle on radiography, and compare with computed tomography (CT). METHODS: Acetabular and lateral iliac angles were measured on frontal pelvic radiographs of 200 patients (400 hips, 183 with DDH) and coronal CT of 20 patients (40 hips) aged 0-12 months...

Metastasis to secondary sites such as the lung, liver and bone is a traumatic event with a mortality rate of approximately 90% (1). Of these sites, the lung is the most difficult to assess using intravital optical imaging due to its enclosed position within the body, delicate nature and vital role in sustaining proper physiology. While clinical modalities (positron emission tomography (PET), magnetic resonance imaging (MRI) and computed tomography (CT)) are capable of providing noninvasive images of this tissue, they lack the resolution necessary to visualize the earliest seeding events, with a single pixel consisting of nearly a thousand cells...

BACKGROUND: In equids, health and welfare depend on body composition. A growing number of equids are now used as leisure and companion animals, and often found overfeed. The need for a close monitoring of body fatness led to the search for tools allowing a rapid and non-invasive estimation of fatness. This study intends to assess real-time ultrasonography (RTU) usefulness in establishing a relationship between ultrasound measures of subcutaneous fat-plus-skin thickness (SF-Skin) and body condition score (BCS) in horses and donkeys...

BACKGROUND: Obesity and emaciation in horses have major detrimental effects on health and morbidity, reproductive failure, work performance or carcass quality. Scoring is a current management tool used to assess and monitor equine body condition due to its simplicity and low cost. However, accurate assessment of obesity remains a challenge, even though a number of approaches have been tested, particularly for research purposes on adiposity. Their merit is usually validated by comparison with standard scoring methods...

BACKGROUND: Systems for estimating body condition score (BCS) are currently used in canine practice to monitor fatness levels. These tools are cheap and easy to use but lack the necessary precision to monitor small changes in body fat, particularly during weight control treatments or in research. The present work aims to study the application of real-time ultrasonography (RTU) together with image analysis in the assessment of subcutaneous fat depots in dogs. Ultrasound images were collected from five anatomical locations (chest, flank, abdomen, thigh and lumbar) from 28 healthy dogs of different breeds and with a body weight (BW) ranging from 5...

Thiophenols are highly toxic industrial materials that once released, will accumulate in environment and ultimately into human bodies, causing serious health problems. To achieve their selective and sensitive detection, herein a novel near-infrared fluorescent probe CCP-1 from a focused library was developed for thiophenol species. Our studies show that CCP-1 displays a thiophenol-triggered 28-fold fluorescence intensity enhancement at 706 nm, with a detection limit of 34 nM observed. It is also able to differentiate thiophenols from various other thiol-containing analytes including hydrogen sulfide, hydrogen persulfide and aliphatic thiols...
