The value of lateral lymphoscintigraphy images of the pelvis for gynecological cancers: Are they necessary?

Introduction: In the current study we evaluated the incremental value of lateral pelvic lymphoscintigraphy imaging of endometrial or cervical cancer patients who underwent sentinel node mapping. Methods: Operable endometrial and cervical cancer patients without clinical or paraclinical evidence of lymph node involvement were included in the study. The day before surgery the patients were sent ...

Sp1 and C/EBP are necessary to activate the lactoferrin gene promoter during myeloid differentiation.

In this study, we sought to identify factors responsible for the positive modulation of lactoferrin (LF), a neutrophil-specific, secondary-granule protein gene. Initial reporter gene transfection assays indicated that the first 89 base pairs of the LF promoter are capable of directing myeloid-specific LF gene expression. The presence of a C/EBP site flanked by 2 Sp1 sites within this segment of...

Are the additional grafts necessary?

The goals of surgery for spinal deformity are to correct or improve the deformity to get a stable, balanced and fused spine. The long-term success of any procedure for scoliosis depends on a solid arthrodesis. Getting fusion of the instrumented segment with the aid of copious autogenous iliac graft has been the most important goal of treatment. However, harvesting copious graft from teenage ili...

Are theories necessary to constrain concepts?

In traditional theories of semantic memory, performance of semantic tasks relies upon a mediating process of categorization. However, categorizationbased theories do not capture the complex and flexible ways in which people use their conceptual knowledge to perform natural semantic tasks imposed on them by the environment. For example, both children and adults understand that a given property m...
