1. Efficacy of serratus anterior plane block versus thoracic paravertebral block for postoperative analgesia after breast cancer surgery - a randomized trial
Abstract Background Breast cancer surgery is associated with considerable acute post-surgical pain and restricted mobility. Various regional and neuraxial anesthesia techniques have been used to alleviate post-mastectomy pain. Ultrasound-guided serratus anterior plane block (SAPB) has been considered a simple and safe technique. This randomized control stud

2. Reduced Graphene Oxide-Cadmium Sulfide Quantum Dots Nanocomposite Based Dispersive Solid Phase Microextraction for Ultra-Trace Determination of Carbamazepine and Phenobarbital
This research presents a fast, sensitive, and selective ultrasound-assisted dispersive solid phase microextraction technique for simultaneous preconcentration and determination of ultra-trace amount of carbamazepine and phenobarbital. Reduced graphene oxide sheets decorated with cadmium sulfide quantum dots was synthesized, characterized, and used as a high

4. Ultrasound guided erector spinae plane block for postoperative analgesia after augmentation mammoplasty: case series
Resumo A mamoplastia de aumento é o terceiro procedimento cirúrgico estético mais feito em todo o mundo. A cirurgia com implantes protéticos requer a inserção de um implante sob o tecido mamário, o que causa dor intensa devido à extensão do tecido e trauma cirúrgico aos tecidos separados. Nesta série de casos, apresentamos o manejo bem-sucedido da

5. Use of artisanal simulators in the ultrasound training for invasive procedures in nephrology: venous access and renal biopsy
RESUMO Introdução: O acesso vascular e a biópsia renal são procedimentos comuns na prática nefrológica. Neste estudo, são apresentados dois simuladores artesanais de baixo custo e excelente qualidade de imagem para guiar, ultrassonograficamente, o acesso venoso e a biópsia renal. Métodos: Os simuladores são construídos utilizando fatias de peito

6. Humoral hypercalcemia of pregnancy treated with bisphosphonates
SUMMARY Hypercalcemia can be hazardous during pregnancy, most cases being due to primary hyperparathyroidism. We report a case of hypercalcemia with suppressed PTH levels necessitating treatment with bisphosphonates during pregnancy. A 38-year-old woman at the 26th week gestation was admitted because of symptomatic hypercalcemia. She did not take any medicat

7. Breast tumor classification in ultrasound images using support vector machines and neural networks
Abstract Introduction The use of tools for computer-aided diagnosis (CAD) has been proposed for detection and classification of breast cancer. Concerning breast cancer image diagnosing with ultrasound, some results found in literature show that morphological features perform better than texture features for lesions differentiation, and indicate that a reduc

8. Breast hamartoma: a clinicopathologic analysis of 27 cases and a literature review
OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, a

9. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

11. Estimates of heritability and genetic correlations for meat quality traits in broilers
Broiler meat quality is one of the primary factors considered by the poultry industry. This study was conducted to estimate heritability and genetic correlation coefficients for meat quality traits in a single male broiler line. The meat ultimate pH (24 h after slaughter) and lightness presented the highest heritability estimates. Given the estimated genetic
