Ultra-long air-stability of n-type carbon nanotube films with low thermal conductivity and all-carbon thermoelectric generators.

This report presents n-type single-walled carbon nanotubes (SWCNT) films with ultra-long air stability using a cationic surfactant and demonstrates that the n-type Seebeck coefficient can be maintained for more than two years, which is the highest stability reported thus far to the best of our knowledge. Furthermore, the SWCNT films exhibit an extremely low thermal conductivity of 0.62 ± 0.

Development of Novel Thermal Diffusivity Analysis by Spot Periodic Heating and Infrared Radiation Thermometer Method.

A spot periodic heating method is a highly accurate, non-contact method for the evaluation of anisotropy and relative thermophysical property distribution. However, accurately evaluating thermal diffusivity is difficult due to the influence of temperature wave reflection from the whole surface of the sample. This study proposes a method to derive thermal diffusivity using a parameter table based on heat transfer equations using the concept of optimum distance between heating-point and measurement point.

Therapeutic anti-inflammatory effects of luteolin on endotoxin-induced uveitis in Lewis rats.

The present study aimed to investigate the therapeutic efficacy of post-inflammatory treatment with luteolin on endotoxin-induced uveitis (EIU) in rats. Intraperitoneal injection of 10 mg/kg luteolin or 1 mg/kg prednisolone (Pred) at 4 hr post-lipopolysaccharide (LPS) injection (200 µg) was associated at 24 hr post-LPS injection with decreased clinical severity scores, number of inflammatory cells, protein levels and levels of tumor necrosis factor (TNF)-α, nitric oxide (NO) and prostaglandin (PG) E2 in the aqueous humor (AqH) and degrees of histological ocular tissue injury. The anti-inflammatory potency of luteolin was comparable to that of Pred.

Luteolin attenuates endotoxin-induced uveitis in Lewis rats.

The aim of the present study was to investigate the efficacy of luteolin on endotoxin-induced uveitis (EIU) in rats. EIU was induced in Lewis rats by subcutaneous injections of lipopolysaccharide (LPS). One hr before the LPS injection, 0.

Tubularized incised plate urethroplasty with dorsal inlay graft prevents meatal/neourethral stenosis: a single surgeon's experience.

Background/purpose: Snodgrass tubularized incised plate urethroplasty (SUP) is versatile and has good cosmesis. However, postoperative meatal/neourethral stenosis (M/N-S) is common enough for some surgeons to add a dorsal inlay graft (DIG) harvested from the inner prepuce and sutured to cover the longitudinal midline incision of the urethral plate. This is the first formal assessment of the effectiveness of DIG for preventing M/N-S.
