Fruits are a prime source of nutrients, bioactive compounds, and dietary fibers. Some products available on the Brazilian market use fruit by-products and claim to have useful effects on human health due to their dietary fiber content. The study aimed to extract and purify the total (28-47 w/w yield) and soluble dietary fiber (4-7 w/w yield) from jaboticaba, papaya, and plum commercial flours sold in Brazil and to study the in vitro biological effects of the fractions.

Bronchoscopic lung cryobiopsy (BLC) has impacted the diagnostic impression and confidence of multidisciplinary discussions (MDDs) in the evaluation of ILD. Reports indicate that a genomic classifier (GC) can distinguish usual interstitial pneumonia (UIP) from non-UIP.

For eligible patients, the treatment of choice includes induction therapy (usually involving newer biologic agents) followed by autologous stem cell transplant; however, this treatment is generally not considered curative, and relapses usually occur. However, extramedullary relapse is an uncommon presentation, and relapses that involve the lungs have only rarely been described.

Pectus excavatum and pectus carinatum are common congenital anomalies that are usually benign but may warrant surgical treatment if they cause compression of vital internal structures. By contrast, developmental variants such as the sternal foramen are asymptomatic and do not require further evaluation or treatment.

This condition can be associated with multiple causes including trauma, inflammation, scarring, or neoplastic involvement of the pericardial space among others. The main pathophysiologic event leading to tamponade is an increase in intrapericardial pressure sufficient to compress the heart with resultant hemodynamic impairment, which leads to limited cardiac inflow, decreased stroke volume, and reduced blood pressure.

Histopathologic examination showed that this was an angiomyolipoma, a tumor that most commonly occurs in the kidney. The preoperative evaluation and intraoperative management are presented, along with a brief review of this unusual neoplasm.

However, cardiovascular complications occur in a significant number of such patients and are the immediate cause of death in some. The spectrum of cardiovascular complications of AIDS that may be depicted at imaging includes dilated cardiomyopathy, pericardial effusion, human immunodeficiency virus-associated pulmonary hypertension, endocarditis, thrombosis, embolism, vasculitis, coronary artery disease, aneurysm, and cardiac involvement in AIDS-related tumors.

Although rare, benign tumors outnumber their primary malignant counterparts three to one. Since mortality varies directly with invasion, identifying the neoplasm at an early stage helps focus treatment, especially in benign cases, which generally respond well to surgical resection.

Although echocardiography establishes the diagnosis in most cases, CT and MRI provide additional physical, spatial, and functional information that further aids the evaluation of metastases. For instance, CT provides superior resolution for detecting calcification or fat, while MRI with its direct multiplanar ability more completely characterizes the heart, pericardium, mediastinum, and lungs.

To explore docetaxel as radiosensitizer in a hypofractionated chest irradiation schedule, a docetaxel dose escalation study was conducted in which 26 patients with advanced non-small-cell lung cancer (NSCLC) (stages III and IV) were enrolled. Docetaxel was administered 24 hours prior to irradiation (starting dose 10mg/m2; escalating in 5mg/m2 increments).

Additionally, the cumulative entrance skin exposure (ESE) using an ion chamber was determined. We retrospectively reviewed the medical records of all adult patients admitted to the MICU, SICU, MICA, and SICA at a tertiary referral center during a 6-month interval.

When not corrected, PDA leads to significant morbidity and mortality, making it a rare condition in the adult population.

Materials And Methods: A tumor cell inoculum (2 x 10(6) cells per 0.15 mL) was injected percutaneously under fluoroscopic guidance at the posterior midaxillary line in 22 athymic nude mice.
Pulmonary involvement is one of the extra-articular manifestations of rheumatoid arthritis (RA) and includes pleurisy, parenchymal nodules, interstitial involvement, and airway disease. Rheumatoid pulmonary vasculitis is rare. Pulmonary disease also may be observed as a toxic event consequent to treatment for RA.

In the seven dogs studied, 19 conductance catheter and simultaneous Cine-CT runs were obtained. High correlation coefficients were found for total volume and segmental volumes, except in the basal segment.

The definition of all components of these anomalies is difficult to accomplish with imaging techniques. This study compared the effectiveness of electrocardiographic (ECG) gated spin-echo magnetic resonance imaging (MRI) with cardiac angiography for the evaluation of all components of central cardiovascular anatomy in patients with the clinical diagnosis of single or common ventricle or complete atrioventricular (AV) septal (canal) defect.
