UNLABELLED The dynamic loading in human body, along with the corrosive body fluid, presents a great challenge for the practical use of biodegradable magnesium implants. In this study, a high purity magnesium (99.99wt.%) and two typical promising biodegradable magnesium alloys (binary Mg-1Ca and ternary Mg-2Zn-0.2Ca) were chosen as the experimental materials. Their dynamic mechanical performance...

Stereotactic body radiation therapy (SBRT) simulations using a Stereotactic Body Frame (SBF: Elekta, Stockholm, Sweden) were expanded to include 18F-deoxyglucosone positron-emission tomography (FDG PET) for treatment planning. Because of the length of time that staff members are in close proximity to the patient, concerns arose over the radiation safety issues associated with these simulations....

Magnesium and its alloys are not normally used as bioresorbable temporary implants due to their high uncontrolled degradation rate in a physiological liquid environment. The improvement of corrosion resistance simulated body fluids (SBF) magnesium alloy (AZ31) coated with poly-β-hydroxybutyrate (PHB) was investigated. Scanning electron microscopy, Fourier transform infrared spectrometer, contac...

In the presence of a soluble organic salt containing non-coordinating anion (e.g., [bmim][SbF(6)] or [NR(4)][SbF(6)]), the catalytic activity of Lewis acid (MX(n)) was dramatically enhanced due to the anion exchange between the Lewis acid and organic salt.

The C(2)-symmetric electron-poor ligand (R)-BINOP-F (4) was prepared by reaction of (R)-BINOL with bis(pentafluorophenyl)-phosphorus bromide in the presence of triethylamine. The iodo complex [CpRu((R)-BINOP-F)(I)] ((R)-6) was obtained by substitution of two carbonyl ligands by (R)-4 in the in situ-prepared [CpRu(CO)(2)H] complex followed by reaction with iodoform. Complex 6 was reacted with [A...

OBJECTIVE Noninvasive evaluation of the cutaneous (cBF) and subcutaneous (sBF) blood flow over the acupuncture point (AP) Gb21 to assess a characteristically increased microcirculation at AP. BACKGROUND AP show several anatomic, histologic and physiologic peculiarities that indicate a specifically elevated microcirculation. Nevertheless cBF and sBF over AP have not yet been established by non...

Electrical stimulation (ES) is a modality used to increase skin blood flow (SBF) and to aid in wound healing. A greater SBF in non wounded skin is induced if ES is used in a warm environment compared to a thermoneutral environment, where ES is usually applied. Therefore, in this paper, a method to investigate the effect of local heating and ES on the SBF is developed. A total of 33 males (18-40...

Aims. To undertake a quasi-experimental study to : i) assess the effect of low cost hygiene and emollient regimes on the SBF of people aged >65 year with xerosis (dry skin) on their lower legs; ii) assess the utility of portable measures of skin barrier function (SBF) in terms of stratum corneum hydration (SCH) and trans-epidermal water loss (TEWL) in community settings iii) provide evidence fo...

background: dental cobalt base alloys are biocompatible dental materials and have been widely used in dentistry. however, metals are bioinert and may not present bioactivity in human body. bioactivity is the especial ability to interact with human body and make a bonding to soft and hard tissues. the aim of the present research was fabrication and bioactivity evaluation of novel cobalt alloy/ f...
