BACKGROUND Although atypical or suspicious cytology may support a clinical diagnosis of a malignancy, it is often not sufficient for the implementation of therapy in patients with pancreatic carcinoma. Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is a relatively new method for obtaining cytology samples, and one that may decrease(More)
BACKGROUND Fine-needle aspiration (FNA) may be the procedure of choice in the preoperative evaluation of thyroid nodules, yet it suffers as a modality both because of its inherent limitations as well as variability in its diagnostic terminology. The National Cancer Institute recently proposed a classification system. The objective of this study was to(More)
Nitric oxide (NO) is now known to control both mitochondrial respiration and organelle biogenesis. Under conditions of ethanol-dependent hepatic dysfunction, steatosis is increased, and this is associated with increased expression of inducible nitric oxide synthase (iNOS). We have previously shown that after chronic exposure to ethanol, the sensitivity of(More)
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy allows the detailed imaging and FNA not only of both intramural and extramural structures and lesions of the gastrointestinal (GI) tract but also of various intraabdominal organs. Thus, EUS-FNA biopsy offers a novel opportunity to evaluate and obtain cytology samples from(More)
An early event that occurs in response to alcohol consumption is mitochondrial dysfunction, which is evident in changes to the mitochondrial proteome, respiration defects, and mitochondrial DNA (mtDNA) damage. S-adenosylmethionine (SAM) has emerged as a potential therapeutic for treating alcoholic liver disease through mechanisms that appear to involve(More)
The effect of using a 30% cutoff for the proportion of HER2+ cells on the interobserver variability in the interpretation of HER2 immunohistochemical results was evaluated. Immunostained sections from 96 cases of breast carcinoma were reviewed by 10 pathologists and scored as positive (3+) when uniform strong membranous staining was identified in at least(More)
BACKGROUND The BRAF V600E mutation has been reported in 50%-80% of papillary thyroid carcinoma (PTC) cases and is highly specific for PTC. Reflex BRAF testing may improve the diagnostic accuracy of thyroid fine-needle aspiration (FNA) tests having equivocal cytologic interpretations and provide prognostic information that helps guide management in patients(More)
An early event that occurs in response to alcohol consumption is mitochondrial dysfunction, which is evident in changes to the mitochondrial proteome, respiration defects, and mtDNA damage. S-Adenosylmethionine (SAM) has emerged as a potential therapeutic for treating alcoholic liver disease through mechanisms that appear to involve decreases in oxidative(More)
We compared the histologic follow-up of 368 smears or slides with an interpretation of "atypical squamous cells, cannot rule out high-grade squamous intraepithelial lesion" (ASC-H) based on conventional and liquid-based preparations and age groups in a high-risk population. Patients with an ASC-H interpretation were 17 to 87 years old (mean, 36.8 years).(More)
