Tracking and Dynamic Tuning of a Wireless Powered Endoscopic Capsule.

This work presents an inductive wireless power transfer system for powering an endoscopy capsule supplying energy to power electronic devices allocated inside a capsule of ≈26.1 mm × 9 mm. A receiver with three coils in quadrature with dimensions of ≈9 mm × 9 mm × 10 mm is located inside the capsule, moving freely inside a transmitter coil with 380 mm diameter through translations and revolutions.

Evaluation of physiological parameters before and after respiratory physiotherapy in newborns with acute viral bronchiolitis.

Background: Acute viral bronchiolitis is a respiratory disease with high morbidity that affects newborn in the first two years of life. Its treatment with physiotherapy has been highlighted as an important tool, however, there is no consensus regarding its effects on patients improvement. We aimed to evaluate the physiological parameters before and after the procedure respiratory therapy in newborn with acute viral bronchiolitis.

Perceptions of the usefulness of external support to immunization coverage in Guinea-Bissau: a Delphi analysis of the GAVI-Alliance cash-based support.

Introduction: Although many countries have improved vaccination coverage in recent years, some, including Guinea-Bissau, failed to meet expected targets. This paper tries to understand the main barriers to better vaccination coverage in the context of the GAVI-Alliance (The Global Alliance for Vaccines and Immunisation) cash-based support provided to Guinea-Bissau.

Methods: The analysis is based on a document analysis and a three round Delphi study with a final consensus meeting.

[Emergency Psychiatric Service in general hospitals: a retrospective study].

The Emergency Psychiatric Service in General Hospitals (SEPHG, acronym in Portuguese) is a service included in the psychiatric reform movement. The purpose of the present study was to characterize patients with psychological distress treated at the Dr. Estevam SEPHG, located in Sobral, Cear state.

Comparative analysis of the expression of proliferating cell nuclear antigen, p53, bax, and bcl-2 in oral lichen planus and oral squamous cell carcinoma.

Several epidemiologic studies have shown the malignant transformation potential of oral lichen planus; however, this potential is subject of much controversy. To evaluate the expression of proteins related to the cell proliferation and apoptosis processes in oral lichen planus, we compared oral lichen planus with oral squamous cell carcinoma. Twenty-four cases of each lesion were submitted according to streptavidin-biotin technique to evaluate the immunohistochemical expression of proliferating cell nuclear antigen, p53, bax, and bcl-2 proteins.

Morphometric and quantitative study of the myenteric neurons of the stomach of malnourished aging rats.

In this work, two groups of Wistar rats were fed ad libitum, one with standard chow (22% protein) and the other with hypoproteic chow (8% protein), from the 210th to the 345th day of life. Compared to the animals fed with standard chow, the animals fed with hypoproteic chow exhibited hypophagia (ingestion about 30% lower), mean weight gain 4.46% lower, greater amount of retroperitoneal and peri-epididymal fat (19% on average), lower Lee index, decrease of total plasma proteins and plasma globulins and maintenance of plasma albumin.

Microbiological or chemical models of enamel secondary caries compared by polarized-light microscopy and energy dispersive X-ray spectroscopy.

Different secondary caries models may present different results. The purpose of this study was to compare different in vitro secondary caries models, evaluating the obtained results by polarized-light microscopy (PLM), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). Standardized human enamel specimens (n = 12) restored with different materials (Z250 conventional composite resin-CRZ, Freedom polyacid-modified composite resin-CRF, Vitremer resin-modified glass-ionomer-GIV, and Fuji IX conventional glass-ionomer cement-GIF) were submitted to microbiological (MM) or chemical caries models (CM).

Glandectomy with preservation of corpora cavernosa in the treatment of penile carcinoma.

Introduction: The objective of this work is to describe a conservative surgical technique as an alternative to classic penile amputations, aiming the local control of the disease, in addition to trying to preserve the patient's sexual function.

Surgical Technique: After a circular incision of the skin around the penis, the subfascial plane is developed until the base of the organ. The dorsal neurovascular bundle and the urethra are isolated in their distal extremities.
