Tomoki Nishiyama
BACKGROUND: To know the objective methods of the effects of the brachial plexus block, we studied the changes in percutaneous oxygen pressure (tcPO₂) with the hypothesis that tcPO₂ increases significantly on the blocked arm in comparison with the non-blocked arm, a phenomenon which is connected with vasodilation following the brachial plexus block. METHODS: Fifteen patients scheduled for upper extremity surgery, aged 20 to 70 years, with ASA physical status I or II were included...

Sluggish Cognitive Tempo (SCT) has been defined by a constellation of caregiver-reported symptoms that includes daydreaming, difficulty initiating and sustaining effort, lethargy, and physical underactivity. These symptoms have been observed in both typically developing children and in some children with Attention-Deficit/Hyperactivity Disorder (ADHD)-especially those with the predominantly inattentive presentation. Symptoms of SCT (typically identified via rating scales) appear separable from DSM inattentive ADHD symptoms, but have also been associated with internalizing symptoms...

In Italy, a "Casa della Salute" (or "House of Health"), translated for the purposes of this article as Community Health Center (CHC), is a public center (of the national public healthcare system), where one can find allocated all primary community healthcare services centered on prevention, treatment and rehabilitation of the citizen in the same physical space, including general practitioner offices, outpatient specialist clinics, and social services. CHCs assure patient-centered primary care services and are the ideal place for applying the Chronic Care Model...

The aim of this observational descriptive study was to identify the main international models evaluating the quality of nursing homes for non self-sufficient elderly persons, and to apply them in the Italian health system. Firstly, a bibliographic search of institutional websites and Pubmed-Medline was performed to identify the main international models. Secondly, three variables were chosen to evaluate the level of implementability of the models: (1) frequency of use of quality indicators in the international models; (2) degree of constructability of the models in two Italian nursing homes; (3) perceived relevance of the indicators used by the chosen models, by nursing home workers...

Understanding transport in rough fractures from non-Fickian to Fickian regimes and the prediction of non-Fickian transport is critical for the development of new transport theories and many practical applications. Through computational experiments that fall within the macrodispersion regime, we first simulated and analyzed solute transport through synthetic rough fractures with stationary geometrical properties (i.e., fracture roughness σb/〈b〉 and correlation length λ, where b refers to aperture with its standard deviation σb and arithmetic mean 〈b〉) across increasing fracture longitudinal transport domain length L, with L/λ ranging from 2...

Total wrist arthroplasty (TWA), first performed in the late 19th Century, is still an infrequently used operation. It is most commonly indicated in patients with rheumatoid arthritis who have pan-carpal wrist involvement. It is an alternative to total wrist arthrodesis in patients who wish to preserve joint motion. Patients must lead a low-demand lifestyle and have failed non-operative measures. Complications are not insignificant and have been reported to be as high as 43%. Modern generation implants most often fail due to dislocation or loosening...

We describe a new algorithmic approach able to automatically pick and track the NMR resonances of a large number of 2D NMR spectra acquired during a stepwise variation of a physical parameter. The method has been named Trace in Track (TINT), referring to the idea that a gaussian decomposition traces peaks within the tracks recognised through 3D mathematical morphology. It is capable of determining the evolution of the chemical shifts, intensity and linewidths of each tracked peak.The performances obtained in term of track reconstruction and correct assignment on realistic synthetic spectra were high above 90% when a noise level similar to that of experimental data were considered...

PURPOSE: The purpose of this double-blind, placebo-controlled study was to examine the effect of two fish oil supplements, one high in EPA (750 mg EPA, 50 mg DHA) and one low in EPA (150 mg EPA, 100 mg DHA), taken acutely as a recovery strategy following EIMD. METHODS: Twenty-seven physically active males (26 ± 4 year, 1.77 ± 0.07 m, 80 ± 10 kg) completed 100 plyometric drop jumps to induce muscle damage. Perceptual (perceived soreness) and functional (isokinetic muscle strength at 60° and 180° s(-1), squat jump performance and countermovement jump performance) indices of EIMD were recorded before, and 1, 24, 48, 72, and 96h after the damaging protocol...

Bowl-like monodispersed porous carbon nanoparticles (BMPCNs) have been successfully prepared with a facile and scalable approach, and the as-prepared BMPCNs are examined thoroughly by various physical characterizations. Physical measurements display that BMPCNs have the high surface area (1255m(2)g(-1)), hierarchical porosity, a certain amount of oxygen-containing groups and high graphitization degree. These unique structure features endow BMPCNs with a high capacitance (281Fg(-1) at 0.5Ag(-1)), excellent rate capability (209Fg(-1) at 50Ag(-1)), and outstanding cycling stability (94...

It is believed that anomalous mental states such as stress and anxiety not only cause suffering for the individuals, but also lead to tragedies in some extreme cases. The ability to predict the mental state of an individual at both current and future time periods could prove critical to healthcare practitioners. Currently, the practical way to predict an individual's mental state is through mental examinations that involve psychological experts performing the evaluations. However, such methods can be time and resource consuming, mitigating their broad applicability to a wide population...

Dicalcium phosphate cements (brushite and monetite) are resorbable biomaterials with osteoconductive potential for bone repair and regeneration that have yet to gain widespread commercial use. Brushite can be converted to monetite by heat treatments additionally resulting in various changes in the physico-chemical properties. However, since conversion is most commonly performed using autoclave sterilisation (wet heating), it is uncertain whether the properties observed for monetite as a result of heating brushite under dry conditions affect resorption and bone formation favourably...
