1. Tadalafil-loaded PLGA microspheres for pulmonary administration: preparation and evaluation
Tadalafil, a long-acting PED-5 inhibitor, is commonly used for the treatment of pulmonary arterial hypertension (PAH). However, its efficacy and clinical application are severely limited by the poor water solubility, low bioavailability and a series adverse effects (e.g. headaches, indigestion). In this study, tadalafil was prepared and loaded into biodegrad

3. Evaluation of the long-term stability of micro-screws under different loading protocols: a systematic review
Abstract: The aim of this systematic review was to investigate the association between the different factors of loading protocols and the long-term stability of micro-screws from biomechanical and histological viewpoints. Searches were performed on PubMed, Embase, Cochrane Library, Wanfang and CNKI databases for animal experiments comparing loading protocols

4. Establishment of a rat model for uterine leiomyomas based on Western and traditional Chinese medicine theories
Uterine leiomyomas (ULs) are benign monoclonal tumors that arise from the underlying myometrial tissue in the uterus. Effective therapies are still lacking because of poor understanding of the pathophysiology and epidemiology. Hence, it is urgent to establish efficient animal models to screen novel anti-UL therapies. In this study, for the first time, tradit

5. Long-term effects of vertical bone augmentation: a systematic review
ABSTRACT Extraction, periodontitis, or trauma can cause a reduction on the alveolar ridge. This could result in an insufficient alveolar bone width and height. Different techniques of vertical bone augmentation are described in literature. However, nowadays there is not enough evidence against lateral augmentation procedures to verify if these techniques are

6. Investigation of Fracture in an Interface Crack Between Bone Cement and Stainless Steel
AbstractInterface strength is considered as one of the most influential factors in the long-term durability of the replaced joint in cemented total hip replacement. Several researchers have suggested that the damage initiation in a replaced joint is a mechanical phenomenon primarily taking place in the vicinity of cement-prosthesis interface. In this study,

7. Load-bearing capacity of screw-retained CAD/CAM-produced titanium implant frameworks (I-Bridge®2) before and after cyclic mechanical loading
Implant-supported screw-retained fixed dental prostheses (FDPs) produced by CAD/ CAM have been introduced in recent years for the rehabilitation of partial or total endentulous jaws. However, there is a lack of data about the long-term mechanical characteristics. OBJECTIVE: The aim of this study was to investigate the failure mode and the influence of exten

8. Estudo da fluência em vigas de concreto reforçado com fibras de aço, com aplicação de conceitos da mecânica da fratura / Creep analysis of steel fiber reinforced concrete based on beam tests and fracture mechanics concepts
Despite of the well known advantages of steel fiber addition to concrete (SFRC), especially the toughness improvement, only a few number of studies has been developed about creep on these composites. The main purpose of this research is to investigate the feasibility and inherent difficulties related to a particular creep evaluation method. This method is ba

9. Artisan fishery of the fleet of Mosqueiro Island (Belem-Pará) and the use of the environment for dourada (fish) (Brachyplatystoma rousseauxii - Castelnau, 1855) / A Pesca artesanal da frota de Mosqueiro (BelémPará) e o uso do ambiente pela dourada (Brachyplatystoma rousseauxii-Castelnau, 1855)
Considering the artisanal landing sites in the Amazon estuary, Mosqueiro Island, located in the south of the Bay of Marajó, is commercially very important and, as in nearby loading terminal (Miramar), the imminence of an environmental disaster is real. However, there is no detailed information on the fishery and the use of commercially important species, as

10. Strengthening of reinforced concrete beams subjected to preloading forces and long-term loads: application of high strength concrete and steel fiber reinforced concrete / Reforço de vigas de concreto armado submetidas a pré-carregamento e ações de longa duração com aplicação de concretos de alta resistência e concretos com fibras de aço
Neste trabalho estudou-se o reforço de vigas T de concreto armado tanto por meio de adição de armadura longitudinal ao bordo tracionado envolvida por um material compósito (argamassa com fibras curtas de aço), quanto pela aplicação de uma capa de pequena espessura de microconcreto de alta resistência ao bordo comprimido. Para estudar as possibilidade

11. Adaptation of canine femoral head articular cartilage to long distance running exercise in young beagles.
OBJECTIVE--To study the effects of long term (one year), long distance (up to 40 km/day) running on the metabolism of articular cartilage the biosynthesis of proteoglycans was examined by in vitro labelling of anterior (weight bearing) and posterior (less weight bearing) areas of the femoral head from young beagles. METHODS--Total sulphate incorporation rate

12. Gait and Stair Function in Total and Resurfacing Hip Arthroplasty: A Pilot Study
Standard total hip arthroplasty (THA) is the established surgical treatment for patients older than 65 years with progressive osteoarthritis but survivorship curves wane in patients younger than 50. Resurfacing hip arthroplasty (RHA) is an alternative for younger, active patients reportedly providing superior range of motion. Quantitative investigation of f
