OBJECTIVE: To apply the principles of the Metro-ticket paradigm to develop a prognostic model for patients undergoing hepatic resection of colorectal liver metastasis (CRLM). BACKGROUND: Whereas the hepatocellular "Metro-ticket" prognostic tool utilizes a continuum of tumor size and number, a similar concept of a CRLM Metro-ticket paradigm has not been investigated. METHODS: Tumor Burden Score (TBS) was defined using distance from the origin on a Cartesian plane incorporating maximum tumor size (x-axis) and number of lesions (y-axis)...

During odor sensing the activity of principal neurons of the mammalian olfactory bulb, the mitral and tufted cells (MTCs), occurs in repetitive bursts that are synchronized to respiration, reminiscent of hippocampal theta-gamma coupling. Axonless granule cells (GCs) mediate self- and lateral inhibitory interactions between the excitatory MTCs via reciprocal dendrodendritic synapses. We have explored long-term plasticity at this synapse by using a theta burst stimulation (TBS) protocol and variations thereof...

OBJECTIVE: Evaluating decisional certainty is an important component of medical care, including preabortion care. However, minimal research has examined how to measure certainty with reliability and validity among women seeking abortion. We examine whether the Decisional Conflict Scale (DCS), a measure widely used in other health specialties and considered the gold standard for measuring this construct, and the Taft-Baker Scale (TBS), a measure developed by abortion counselors, are valid and reliable for use with women seeking abortion and predict the decision to continue the pregnancy...

: Trabecular bone score, an indirect measure of bone structure, may differ between ethnicities. We found that African Americans had lower trabecular bone score than do whites referred for densitometry, even when controlling for age and abdominal soft tissue thickness. PURPOSE: Trabecular bone score (TBS), an indirect measure of bone structure, has been shown to predict fractures in predominantly white populations. Analysis of NHANES data revealed lower TBS in African Americans than in whites...

: The thresholds of trabecular bone score (TBS) require validation for clinical application in older Chinese people. The lower threshold of TBS significantly improved the accuracy of prediction by bone mineral density-based osteoporosis status for major osteoporotic fracture in older Chinese men. INTRODUCTION: Trabecular bone score (TBS) is a relatively new indicator of skeletal fragility. Its clinical application warrants further investigations. Our aim was to validate and recommend practical thresholds of TBS for fracture prediction in older Chinese people...

We report on the internal configurations of aqueous dispersions of droplets of cholesteric liquid crystals (LCs; 5-50 μm-in-diameter; comprised of 4-cyano-4'-pentylbiphenyl and 4-(1-methylheptyloxycarbonyl)phenyl-4-hexyloxybenzoate) and their influence on the positioning of surface-adsorbed colloids (0.2 or 1 μm-in-diameter polystyrene (PS)). When N = 2D/P was less than 4, where D is the droplet diameter and P is the cholesteric pitch, the droplets adopted a twisted bipolar structure (TBS) and colloids were observed to assume positions at either the poles or equator of the droplets...

BACKGROUND: Retinol isotope dilution (RID) equations are used to determine vitamin A status and the efficacy of vitamin A intervention programs. Recent work related to RID methods has focused on modifying the "Olson equation" to improve the accuracy of predictions of vitamin A total body stores (TBS) in individual subjects. OBJECTIVE: We investigated the hypothesis that short-term restriction of vitamin A intake would result in accurate RID prediction of vitamin A TBS in individuals...

The hippocampal synapses display a conspicuous ability for long-term plasticity, which is thought to contribute to learning and memory. Previous research has shown that long-term potentiation (LTP) greatly differs between the dorsal (DH) and ventral (VH) CA1 hippocampal synapses when induced by high-frequency stimulation. In this study, using rat hippocampal slices and more physiologically relevant activity patterns based on the frequency of the theta rhythm (i.e., theta-burst stimulation, TBS) we found that the DH compared with the VH displayed a higher ability for induction and stability of NMDA receptor-dependent LTP of the field excitatory postsynaptic potential...

Repetitive transcranial magnetic stimulation (rTMS) induces changes in expression of proteins engaged in activity of excitatory and inhibitory systems as well as redox homeostasis. Our aim was to investigate the effect of single (SS) and repeated session (RS) of intermittent and continuous theta-burst stimulation (iTBS; cTBS) on the expression of vesicular and plasmatic glutamate transporters 1 (vGluT1 and GLT-1), glial fibrillary acidic protein (GFAP) and influence on oxidative status in rats cerebellar tissue and plasma...

Dorsal pre-motor cortex (PMd) is thought to play a role in fine motor control. The aim of the present study was to investigate whether inhibitory or excitatory stimulation of PMd would have an impact on manual dexterity in Parkinson's disease (PD). Fifteen patients with PD participated in this study. High resolution structural MRI was used for neuro-navigated TBS. Participants were targeted with one train of TBS in three experimental sessions: sham stimulation over vertex, continuous TBS (cTBS) over PMd and intermittent TBS (iTBS) over PMd, respectively...

The standard method to determine the output level of acoustic and mechanical stimulation to the inner ear is measurement of vibration response of the stapes in human cadaveric temporal bones (TBs) by laser Doppler vibrometry. However, this method is reliable only if the intact ossicular chain is stimulated. For other stimulation modes an alternative method is needed. The differential intracochlear sound pressure between scala vestibuli (SV) and scala tympani (ST) is assumed to correlate with excitation. Using a custom-made pressure sensor it has been successfully measured and used to determine the output level of acoustic and mechanical stimulation...

In the absence of a fragility fracture, osteoporosis is usually diagnosed from bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA). Osteoporosis is an increasingly prevalent disease, as is diabetes [in particular type 2 diabetes (T2D)], in part due to aging populations worldwide. It has been suggested that an increased risk of fracture may be another complication ensuing from longstanding diabetes. The purpose of this review is to concentrate on skeletal parameters and techniques readily available from DXA scanning, and their utility in routine clinical practice for predicting fracture risk...

Hypoparathyroidism (HypoPT) is an uncommon endocrine disorder characterized by chronic deficiency or absence of parathyroid hormone (PTH), which leads to a profound reduction in bone remodeling. Subjects with HypoPT typically have bone mineral densities (BMDs) by dual-energy X-ray absorptiometry (DXA) above average at all skeletal sites, with greatest scores observed at the lumbar spine. Trabecular bone score (TBS), an indirect measure of bone microarchitecture, also appears to be normal in HypoPT. By peripheral quantitative computed tomography (pQCT) of the radius, volumetric BMD at cancellous and cortical compartments, as well as cortical area and thickness, are greater in hypoparathyroid subjects than in controls...

: The association of trabecular bone score (TBS) with fracture risk and its added predictive value to FRAX® for clinical use have never been independently evaluated in a Chinese population. TBS may improve the predictive power of FRAX® for clinical use in older Chinese men. INTRODUCTION: Trabecular bone score (TBS) of lumbar spine on Dual X-ray densitometry provides information on bone architecture. We therefore examined the additive value of TBS to FRAX® in predicting major osteoporotic fractures (MOFs) in older Chinese people...
