Robot-assisted extravascular stent for nutcracker syndrome: A case report.

Nutcracker syndrome (NCS) is a rare condition caused by compression of the left renal vein (LRV) between the aorta and superior mesenteric artery. Surgical treatment is reserved for patients with severe symptoms and failure of conservative treatment. A 31-year-old woman diagnosed in adolescence with NCS has had recurrent pain since age 15.

The porosity of carbohydrate-based spray-dried microparticles containing limonene stabilized by pea protein: Correlation between porosity and oxidative stability.

In this study, the effects of different concentrations of pea protein concentrate (PPC) in the physical properties, porosity features, and oxidative stability of maltodextrin-based spray-dried microparticles containing orange essential oil (OEO, rich in limonene) were evaluated. The use of PPC resulted in spray-dried microparticles with encapsulation efficiencies of about 99 wt%, without visible pores, and relatively high glass transition temperature (66,4 °C) at A ∼ 0.3.

Prospection of the use of encapsulation in food packaging.

Food safety and extended shelf life linked to convenience were the major reasons for the development of the packaging field. However, advances in material science and the widespread encapsulation technologies are allowing the establishment of new concepts for packages, such as intelligent and active packages. Particulate systems have been developed in recent years for the most diverse area with several purposes that can be employed to improve packaging performance mainly focusing on the modification of barrier properties.

Performance of oil-in-water emulsions stabilized by different types of surface-active components.

The emulsion stability depends on the physicochemical properties of the dispersed phase and their interaction with the continuous phase. Surface-active compounds (SAC) are added in emulsions to reduce the interfacial tension (IT) between these phases and keep the oil droplets stabilized. Moreover, small amounts of SAC can occupy intermolecular voids in the dried matrix, reducing the oxidation.

Cystic phaeochromocytoma is a distinctive subgroup with special clinical, imaging and histological features that might mislead the diagnosis.

Objective: To report and analyse cases of cystic phaeochromocytoma at our institution and in previous publications, as adrenal cystic masses are usually associated with nonfunctional lesions, but they can be phaeochromocytoma.

Patients And Methods: The prospective adrenalectomy database at our institution was reviewed to identify patients with phaeochromocytoma and cystic lesions. The clinical, radiological and histological features of cystic phaeochromocytoma were evaluated.

Comparative study of the protective effect of different intravenous bisphosphonates on the decrease in bone mineral density in patients submitted to radical prostatectomy undergoing androgen deprivation therapy. A prospective open-label controlled study.

Objectives: To establish whether androgen deprivation therapy (ADT) promotes osteoporosis and osteopenia

Methods: Ninety-four prostatectomized men with rising prostrate-specific antigen (PSA) were enrolled into the placebo group (31), monthly i.v. clodronate (39) or monthly i.
