INTRODUCTION A regimen with rilpivirine (RPV), abacavir (ABC) and lamivudine (3TC) is simple and may allow the sparing of tenofovir and protease inhibitors. However, data on use of this combination as a strategy of switch are limited. Aims of the study were to assess the long-term efficacy and safety of this regimen. METHODS Retrospective study on HIV-1 infected patients followed at the Infec...

OBJECTIVES The purpose of this study was to evaluate the prevalence of alveolar bone loss (BL) in healthy children treated at private pediatric dentistry clinics in Brasília, Brazil. MATERIAL AND METHODS The research included 7,436 sites present in 885 radiographs from 450 children. The BL prevalence was estimated by measuring the distance from the cementoenamel junction (CEJ) to alveolar bon...

The atom-bond connectivity (ABC) index is one of the most investigated degreebased molecular structure descriptors with a variety of chemical applications. It is known that among all connected graphs, the trees minimize the ABC index. However, a full characterization of trees with a minimal ABC index is still an open problem. By now, one of the proved properties is that a tree with a minimal AB...

BACKGROUND This study provides a replication of the Falls Efficacy Scale (FES) and a head-to-head comparison with the Activities-specific Balance Confidence (ABC) Scale designed to include a wider continuum of activity difficulty and more detailed item descriptors. METHODS Items for the newly developed 16-item ABC Scale were generated by 15 clinicians and 12 elderly outpatients. Psychometric ...

BACKGROUND The epidermal growth factor receptor (EGFR) is overexpressed in many cancers including lung, ovarian, breast, head and neck and brain. Mutation of this receptor has been shown to play a crucial role in the response of non-small cell lung carcinoma (NSCLC) to EGFR-targeted therapies. It is envisaged that imaging of EGFR using positron emission tomography (PET) could aid in selection o...

BACKGROUND Hypersensitivity reaction (HSR) is a major adverse effect of abacavir (ABC), which occurs in 5-8% of Caucasians. The relationship between Human Leukocyte Antigen (HLA) and ABC HSR has been reported in various populations. It has been proposed to administer ABC only to HLA-B*5701 negative patients to avoid this reaction. The purpose of this study was to assess the prevalence of HLA-B*...

Optimal Reactive Power Flow (ORPF) is a branch problem in the gradual development of the optimal power flow problem. Differential Evolution (DE) has been proved to be a promising evolutionary algorithm for solving the ORPF problem, but it requires a relatively large population size to avoid premature convergence, which will increase the algorithm convergence time. On the other hand, Artificial ...
