Our goal was to develop a method to identify the optimal elastic modulus, Poisson's ratio, porosity, and permeability values for a mechanically stressed bone substitute. We hypothesized that a porous bone substitute that favors the transport of nutriments, wastes, biochemical signals, and cells, while keeping the fluid-induced shear stress within a range that stimulates osteoblasts, would likel...

QUESTION In people with sciatica in primary care, can a single question be used to predict outcome at 1 year followup as accurately as validated questionnaires on kinesiophobia, disability, and health-related quality of life? DESIGN Observational study within a randomised cohort. PARTICIPANTS 135 people with sciatica in primary care. OUTCOME MEASURES Kinesiophobia was measured with the Ta...

Active doping of B was observed in nanometer silicon layers confined in SiO(2) layers by secondary ion mass spectrometry (SIMS) depth profiling analysis and confirmed by Hall effect measurements. The uniformly distributed boron atoms in the B-doped silicon layers of [SiO(2) (8 nm)/B-doped Si(10 nm)](5) films turned out to be segregated into the Si/SiO(2) interfaces and the Si bulk, forming a di...

let r be a commutative ring with non-zero identity and m be a unital r-module. then the concept of quasi-secondary submodules of m is introduced and some results concerning this class of submodules is obtained

Wounds with full-thickness skin loss are commonly managed by skin grafting. In the absence of a graft, reepithelialization is imperfect and leads to increased scar formation. Biomaterials can alter wound healing so that it produces more regenerative tissue and fewer scars. This current study use the new chitosan based biomaterial in full-thickness wound with impaired healing on rat model. Wound...

Hypospadias is the most common penile congenital anomaly [2] and the second most common congenital malformation in males, occurring in approximately one in 125 live male births [3]. Two theories were suggested for development of hypospadias, endodermal theory and ectodermal theory [4]. Types of hypospadias are anterior, middle and posterior with the posterior type account approximately 20% of c...

Aggressive neoplasms of the scalp need a wide and deep excision to obtain safe margins and tumor eradication [1]. These considerations sometimes lead to the inclusion of the periosteum as part of wide local excision. The consequence of large surgical excision of the scalp is the exposure of the skull bone with its poor vascularization, therefore a slow granulation and, eventually, a difficult h...

Clinical and histopathological results of the hyaluronic acid skin substitute treatment of the patients who admitted to Inonu University Medical Faculty Plastic Reconstructive and Aesthetic Surgery clinic between january 2011 and march 2012 were evaluated. The patients were divided into two groups. HA were used for treatment of Hypertrophic scar (HS) or Keloid (K) in 10 patients of the first gr...

bachground: hadron therapy is a novel technique of cancer radiation therapy which employs charged particles beams, 1 h and light ions in particular. due to their physical and radiobiological properties, they allow one to obtain a more conformal treatment, sparing better the healthy tissues located in proximity of the tumor and allowing a higher control of the disease.   objective: as it is well...

There have been several studies on the kinetics of . oxygen uptake (VO2) responding to impulse work (Bakker et al., 1980; Hughson et al., 1988; Swanson, 1990; Whipp and Ward, 1991), and it has been demonstrated . that VO2 is composed of two components (phase I and phase II). With regard to these components, Hughson et al. (1988) have suggested that phase I reflects an immediate increase in pulm...
