In construction of epithelial cells as multilayers, the cells are grown submerged to confluence on fibroblast-embedded collagen gels and, then, lifted to air to promote their stratification. We recently demonstrated that gingival epithelial cells form uniform monolayers on semi-permeable nitrocellulose membranes, supported with a semi-solid growth medium, which allows the cells to grow at an air-liquid-solid interface from the beginning of the culturing protocol. In this study, the aim was to further develop our previous model to form a multilayered gingival epithelial culture model...

Medical rounds in the Pediatric Intensive Care Unit (PICU) took about four hours each day to complete. The length of rounds was affecting the advancement of care of the patients, the engagement of sub-specialty providers who needed to be present on other rounds, and the engagement of the PICU faculty and staff due to overburdening waste created by the long duration of rounds. Specific interventions were identified aimed at reducing the duration of rounds each day, increasing engagement of the rounding team and satisfying the needs of the patients and families...

INTRODUCTION: The term oro-antral fistula is understood to mean of fistular canal covered with epithelia which may or may not be filled with granulation tissue or polyposis of the sinus mucous membrane. With the presence of a fistula the sinus is permanently open, which enables the passage of microbial flora of the oral cavity into the maxillary sinus and the occurrence of inflammation with all possible consequences. Every now and then various researchers have proposed innumerable techniques to treat this defect...

We identified factors protective of all-cause sickness absence (SA) among subjects with multisite musculoskeletal pain (MSP). The nationally representative source sample comprised 3420 actively working Finns aged 30-55 in year 2000 and alive at follow-up. Pain in 18 body locations was combined into four sites (neck, low back, upper limbs, lower limbs). The baseline prevalence of MSP (pain in ≥ 2 sites) was 32 %. Baseline data on sociodemographic factors, work ability, work, health, and lifestyle were gathered by questionnaire, interview and clinical examination and linked with national registers on all-cause SA (periods lasting ≥10 workdays) for 2002-2008...

BACKGROUND: Owing to its potentially greater mechanical force on the implanted tissue, barbed thread is frequently used in face-lifting procedures. However, the long-term durability thereof remains controversial. Moreover, reports on underlying histologic and molecular changes resulting from face-lifting procedures are scarce. OBJECTIVE: To evaluate histologic and molecular changes induced by absorbable, barbed face-lifting thread in an animal model. MATERIALS AND METHODS: Fragments of monofilament, monodirectionally barbed polydioxanone thread were implanted in dorsal skin from 12 guinea pigs...

BACKGROUND: Sinus lift is a bone augmentation procedure that improves the alveolar crest height in an atrophic posterior maxilla. However, the regenerated bone volume can vary and generally has a tendency to decrease after sinus operation. This article describes nongrafted maxillary sinus lift using a bioresorbable unsintered hydroxyapatite combined with poly L-lactide (HA/PLLA) mesh plate device and dental implant placement in an atrophic posterior maxilla, after which continuous bone gain was observed around the implant apex during a postoperative follow-up period of 3 years...

Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, allografts, and xenografts) and without grafting material, having new bone formation around the implant. There is no evidence to prove the need for grafting material in all direct sinus lift procedures, hence the need for this review...

BACKGROUND: Mask ventilation (MV) is an essential basic life support skill. We used chin lift maneuver for MV and named as modified chin lift technique (MCL). EC technique is most common technique used for MV. AIMS: The aim of this study is to compare the efficacy of both techniques for MV in term of expired tidal volume (TV). Secondarily, we also assessed the effect of experience on the performance of these both techniques. SETTINGS AND DESIGN: The study area was operation theater of our hospital...

BACKGROUND: Transfer of a flexor hallucis longus (FHL) tendon can not only reconstruct the Achilles tendon but also provide ischemic tendinous tissues with a rich blood supply to enhance wound healing. This retrospective study aims to investigate clinical outcomes in patients who underwent repair of Kuwada grade IV chronic Achilles tendon rupture with long hallucis longus tendons harvested using a minimally invasive technique. MATERIALS AND METHODS: 35 patients who were treated for Kuwada grade IV Achilles tendon injuries from July 2006 to June 2011 were included in this retrospective study...

Objectives Previous research has shown that sensitivity to movement-evoked pain is associated with higher scores on self-report measures of disability in individuals who have sustained whiplash injuries. However, it remains unclear whether sensitivity to movement-evoked pain is associated with work-disability. The aim of the present study was to examine the relation between sensitivity to movement-evoked pain and occupational status in individuals receiving treatment for whiplash injury. Methods A sample of 105 individuals with whiplash injuries participated in a testing session where different measures of pain (i...

The purpose of this study was to investigate the effects of posture of a ski jumper on aerodynamic characteristics during the take-off using computational fluid dynamics (CFD). The CFD method adopted for this study was based on Large-Eddy Simulation. Body surface data were obtained by 3-D laser scanning of an active ski jumper. Based on video analysis of the actual take-off movement, two sets of motion data were generated (world-class jumper A and less-experienced jumper B). The inlet flow velocity that corresponds to the in-run velocity in actual ski jumping was set to 23...

Because the perceived weight of objects may be affected by various nonweight properties, such as their size and the density of their surface material, relative weight is sometimes misperceived (the size-weight illusion and the material-weight illusion, respectively). A widely accepted explanation for weight illusions is provided by the so-called expectation model, according to which the perceived weight stems from the contrast between the actual and expected weights. In the present study, we varied both the surface material and the size of stimuli, while keeping constant their physical weights...

The authors' purpose was to test the effect of asymmetric hand lifting on muscular activation patterns of 3 bilateral extensors. Eighteen male university students without back pain were volunteered. Each performed flexion-extension randomly with conditions of right lifting, left lifting, and nonlifting. Surface electromyography from bilateral thoracic, lumbar erector spinae, and hamstring was recorded. The cross-correlation and relative intensity in paired muscles of bilateral extensors was calculated in flexion as well as extension period...

The elastic fingering phenomenon occurs when two confined fluids are brought into contact, and due to a chemical reaction, the interface separating them becomes elastic. We study elastic fingering pattern formation in Newtonian fluids flowing in a lifting (time-dependent gap) Hele-Shaw cell. Using a mode-coupling approach, nonlinear effects induced by the interplay between viscous and elastic forces are investigated and the weakly nonlinear behavior of the fluid-fluid interfacial patterns is analyzed. Our results indicate that the existence of the elastic interface allows the development of unexpected morphological behaviors in such Newtonian fluid flow systems...

Adhesion of circulating tumor cells (CTCs) to the microvessel wall largely depends on the blood hydrodynamic conditions, one of which is the blood viscosity. Since blood is a non-Newtonian fluid, whose viscosity increases with hematocrit, in the microvessels at low shear rate. In this study, the effects of hematocrit, vessel size, flow rate and red blood cell (RBC) aggregation on adhesion of a CTC in the microvessels were numerically investigated using dissipative particle dynamics. The membrane of cells was represented by a spring-based network connected by elastic springs to characterize its deformation...

AIM: Publicly-funded atorvastatin required prior approval until September 2010 whereas simvastatin did not. Our aim was to examine if overall statin dispensing and atorvastatin dispensing among patients hospitalised for cardiovascular disease (CVD) differed systematically across sociodemographic groups during and after special authority criteria. METHOD: National medication dispensing data were anonymously linked to patients hospitalised across New Zealand with CVD and discharged between 1/07/2009-31/12/2009 when special authority criteria applied and 1/09/2010-28/02/2011 after restrictions ceased...

Injuries involving rupture of the pectoralis major are relatively rare. When they do occur, it is mostly frequently in a young, athletic man. The most common cause is weight lifting that results in eccentric muscle contraction (muscle contraction against an overbearing force, leading to muscle lengthening)-specifically, the bench press. Other mechanisms for this injury include forceful abduction and external rotation of the arm. Injury can occur anywhere along the pectoralis major from its medial origin on the sternum and clavicle to its lateral tendinous insertion on the humerus...
