AIM This study has aimed to evaluate the added value of SPECT-CT scan in the preoperative assessment of sentinel nodes of the presacral and pararectal regions localized outside the standard area of extended pelvic lymphadenectomy for the staging of the pelvis in prostate cancer. SPECT-CT scan can serve as a guide for the excision of these nodes by lymphadenectomy by open surgery or laparoscopy....

A novel mosquito trapping system, the BG-Sentinel trap, was evaluated as a monitoring tool for adult Aedes aegypti in field tests in the city of Belo Horizonte, Brazil. Human landing/biting collections, a gas-powered CO2 trap, and a Fay-Prince trap with only visual cues serving as references to evaluate the efficacy of the new trap. The BG-Sentinel is a simple suction trap that uses upward-dire...

Interspecific communication is common in nature, particularly between mutualists. However, whether signals evolved for communication with other species, or are in fact conspecific signals eavesdropped upon by partners, is often unclear. Fork-tailed drongos (Dicrurus adsimilis) associate with mixed-species groups and often produce true alarms at predators, whereupon associating species flee to c...

Sentinel lymph nodes are the first draining nodes that contain tumor cells. Identification of sentinel nodes may help to determine the suitable extent of lymphadenectoy. To assess the location of sentinel lymph nodes, a series of 41 patients with single and two metastatic lymph nodes who underwent esophagectomy and 3-field lymphadenectomy between 1991 and 1999 were investigated retrospectively....

INTRODUCTION Evidence supporting the use of Sentinel node biopsy (SNB) for nodal staging of early oral squamous cell carcinomas (OSCC) appears to be very promising. Pre-operative lymphatic mapping using planar lymphoscinitigraphy (PL) with or without SPECT/CT in the SNB procedure is useful in sentinel node localization and for planning appropriate surgery. Recently, a large prospective multi-ce...

introduction: stroke is one of the most important reasons of death. hence, trials to prevent or lessen the complications originated by stroke are a goal of public health worldwide. the ischemia-reperfusion causes hypoxia, hypoglycemia and incomplete repel of metabolic waste products and leads to accumulation of free radicals triggering neuronal death. the a1 adenosine receptoras an endogenous l...

Sentinel node biopsy can decrease the morbidity of breast cancer treatment significantly by sparing many patients of axillary lymph node dissection and resulting arm lymphedema. Despite widespread use of sentinel node mapping for breast cancer patients almost all aspects of this procedure are controversial; such as: type of the radiotracer, eligibility, time of injection, etc. One of these con...
