Fluorescent nanodiamonds (FNDs) are promising nanoprobes, owing to their stable and magnetosensitive fluorescence. Therefore they can probe properties as magnetic resonances, pressure, temperature or strain. The unprecedented sensitivity of diamond defects can detect the faint magnetic resonance of a single electron or even a few nuclear spins. However, these sensitivities are only achieved if the diamond probe is close to the molecules that need to be detected. In order to utilize its full potential for biological applications, the diamond particle has to enter the cell...

BACKGROUND: Falls are a leading cause of preventable harm in the hospitalized elderly, and head impacts (HIs) can be a precursor to serious injury. The aim of this study was to examine if the risk of fall-related HI can be explained by incident characteristics. METHODS: All reported falls across public hospital facilities in the state of Queensland, Australia, over a 2-year period were analyzed using univariate and multiple logistic regression. RESULTS: In all, 650 instances of HI were reported across 24 218 falls...

OBJECTIVE: Billroth II procedures (gastrojejunostomy with vagotomy) are seldom performed now, but were popular before the advent of histamine 2 (H2) receptor blockers and proton pump inhibitors (PPIs). Such procedures can be a cause of late postprandial hypoglycemia. METHOD: Formal evaluation, discussion of postprandial hypoglycemia. RESULTS: We present a case of an 85-year-old man who presented to the Endocrinology clinic with a complaint of "fainting spells following large meals...

We report the imaging findings of a patient with disseminated Mycobacterium avium-intracellulare complex presenting with multiple splenic lesions incompletely characterized on computed tomography in whom magnetic resonance imaging helped narrow the differential diagnosis. We discuss the magnetic resonance imaging findings suggesting the diagnosis, including the presence of focal susceptibility artifact within the lesions (ie, signal drop on T1 in-phase imaging), marked hypointensity on diffusion-weighted imaging, and faint progressive peripheral enhancement after contrast administration...

Expression of the cell adhesion molecule (CAM), Sialyl Lewis X (CD15s) correlates with cancer metastasis, while expression of E-selectin (CD62E) is stimulated by TNF-α. CD15s/CD62E interaction plays a key role in the homing process of circulating leukocytes. We investigated the heterophilic interaction of CD15s and CD62E in brain metastasis-related cancer cell adhesion. CD15s and CD62E were characterised in human brain endothelium (hCMEC/D3), primary non-small cell lung cancer (NSCLC) (COR-L105 and A549) and metastatic NSCLC (SEBTA-001 and NCI-H1299) using immunocytochemistry, Western blotting, flow cytometry and immunohistochemistry in human brain tissue sections...

BACKGROUND: Rare diseases may elude diagnosis due to unfamiliarity of the treating physicians with the specific disorder. Yet, advances in genetics have tremendously enhanced our ability to establish specific and sometimes surprising diagnoses. CASE PRESENTATION: We report a case of renal Fanconi syndrome associated with intermittent hypoglycemic episodes, the specific cause for which remained elusive for over 30 years, despite numerous investigations, including three kidney and one liver biopsy...

Keeping of infected dogs as pet results in the potential transmission risk factors for shedding helminthic infections such as toxocariasis. Lack of accurate identification of Toxocara canis eggs in non-dewormed infected pet dogs remains a diagnostic concern among researchers. In this study, dog owners were asked to fill up a questionnaire regarding their pets and their attitude towards the deworming regimen. One hundred faecal samples were collected from pet dogs (Northwest Iran) and were subsequently identified by the ZnSo4 flotation technique, PCR and loop-mediated isothermal amplification (LAMP) assays...

Peptide receptor radionuclide therapy (PRRT) either using Lu-177 or Y-90 peptide radiopharmaceuticals has emerged as promising treatment modality in patients with inoperable metastatic neuroendocrine tumour (NET) including medullary thyroid cancer, because of overexpression of somatostatin receptor 2 (sstr-2) on these cells. The several investigators have used PRRT in non-iodine avid differentiated thyroid cancer patients with limited success, where other treatment modalities have failed, probably due to faint sstr-2 expression in these lesions...

The degree of insensitivity to atmospheric turbulence was evaluated for five metrics (A-, B-, E-weighted sound exposure level, Stevens Mark VII Perceived Level, and NASA's Indoor Sonic Boom Annoyance Predictor) that correlate to human annoyance from sonic booms. Eight N-wave shaped sonic booms from NASA's FaINT experiment and five simulated "low-boom" sonic booms were turbulized by Locey's ten atmospheric filter functions. The B-weighted sound exposure level value changed the least due to the turbulence filters for twelve of thirteen booms...

Primary virulence factors of Pseudomonas syringae pv. tomato DC3000 include the phytotoxin coronatine (COR) and a repertoire of 29 effector proteins injected into plant cells by the type III secretion system (T3SS). DC3000 derivatives differentially producing COR, the T3SS machinery, and subsets of key effectors were constructed and assayed in leaves of Nicotiana benthamiana. Bacteria were inoculated by dipping of whole plants and assayed for population growth and production of chlorotic spots on leaves. The strains fell into three classes...

Sawako Yamashiro, Naoki Watanabe
Single-molecule speckle (SiMS) microscopy is a powerful method to directly elucidate biochemical reactions in live cells. However, since the signal from an individual fluorophore is extremely faint, the observation area by epi-fluorescence microscopy is restricted to the thin cell periphery to reduce autofluorescence, or only molecules near the plasma membrane are visualized by total internal reflection fluorescence (TIRF) microscopy. Here, we introduce a new actin probe labeled with near infrared (NIR) emissive CF680R dye for easy-to-use, electroporation-based SiMS microscopy (eSiMS) for deep-cell observation...

#14
REVIEW
Paolo Alboni, Marco Alboni
Many observations suggest that typical (emotional or orthostatic) vasovagal syncope (VVS) is not a disease, but rather a manifestation of a non-pathological trait. Some authors have hypothesized this type of syncope as a "defense mechanism" for the organism and a few theories have been postulated. Under the human violent conflicts theory, the VVS evolved during the Paleolithic era only in the human lineage. In this evolutionary period, a predominant cause of death was wounding by a sharp object. This theory could explain the occurrence of emotional VVS, but not of the orthostatic one...

Erica Simon, Alicia E Meuret, Thomas Ritz
The autonomic regulation in blood-injection-injury (BII) phobia has received particular attention due to the unique link between fear and fainting in this anxiety disorder. However, systematic exploration of sympathetic and parasympathetic cardiac activity during exposure to phobia-relevant emotional stimuli has remained rare and inconclusive, including with regard to disgust, a frequent response to BII stimuli. Existing studies using respiratory sinus arrhythmia (RSA) as a noninvasive index of parasympathetic cardiac activity also have not accounted sufficiently for effects of respiration...

Cholinergic urticaria occasionally occurs in combination with anaphylactic symptoms. However, this has not been widely reported. Herein, we report the case of a 14-year-old Japanese male who was diagnosed with cholinergic urticaria accompanied by anaphylaxis. The patient, who was suffering from atopic dermatitis and bronchial asthma, had developed wheals after exercising or bathing, which would have increased his core body temperature, since summer 2014. He experienced two episodes of severe systemic symptoms and wheal development when he took a bath after eating in December 2014 and the following January...

BACKGROUND: Epilepsy is a common neurological condition with a worldwide prevalence of around 1%. Approximately 60% to 70% of people with epilepsy will achieve a longer-term remission from seizures, and most achieve that remission shortly after starting antiepileptic drug treatment. Most people with epilepsy are treated with a single antiepileptic drug (monotherapy) and current guidelines from the National Institute for Health and Care Excellence (NICE) in the United Kingdom for adults and children recommend carbamazepine or lamotrigine as first-line treatment for partial onset seizures and sodium valproate for generalised onset seizures; however a range of other antiepileptic drug (AED) treatments are available, and evidence is needed regarding their comparative effectiveness in order to inform treatment choices...

Postprandial hyperglycemia is a risk factor for cardiovascular diseases. It has been reported that intragastric administration of allyl isothiocyanate (AITC), which is one of the pungent ingredients of wasabi and horseradish but it is not included in hot chili pepper, increased carbohydrate oxidation and reduced postprandial increase of blood glucose via transient receptor potential vanilloid 1 (TRPV1)in mice. However, the action site of AITC on TRPV1 for increasing carbohydrate oxidation is unclear. Both mammalian and chicken TRPV1 (cTRPV1) are activated by heat and acid, but unlike its mammalian counterpart, cTRPV1 is only faintly activated by capsaicin...

Stool-based rapid diagnostic tests (RDTs) for pathogenic intestinal protozoa (e.g. Cryptosporidium spp. and Giardia intestinalis) allow for prompt diagnosis and treatment in resource-constrained settings. Such RDTs can improve individual patient management and facilitate population-based screening programmes in areas without microbiological laboratories for confirmatory testing. However, RDTs are difficult to interpret in case of 'trace' results with faint test band intensities and little is known about whether such ambiguous results might indicate 'true' infections...
