BACKGROUND: Preoperative lymphoscintigraphy is one of the three methods of evaluating sentinel nodes in patients with breast cancer; however, it has been reported to have a high false negative rate. CASE PRESENTATIONS: We report here two cases where the preoperative lymphoscintigraphy was found to be fallacious. A 44-year-old female with T2N0 breast cancer underwent preoperative lymphoscintigra...

BACKGROUND Theoretical analyses of the indigo dye molecule and its derivatives with Chlorine (Cl), Sulfur (S), Selenium (Se) and Bromine (Br) substituents, as well as an analysis of the Hemi-Indigo molecule, were performed using the Gaussian 03 software package. RESULTS Calculations were performed based on the framework of density functional theory (DFT) with the Becke 3- parameter-Lee-Yang-P...

A new class of nanostructured hybrid materials is developed by direct grafting of a model thiophene-based organic dye on the surface of 3C-SiC/SiO2 core/shell nanowires. TEM-EDX analysis reveals that the carbon distribution is more spread than it would be, considering only the SiC core size, suggesting a main contribution from C of the oligothiophene framework. Further, the sulfur signal found ...

In the present study, twenty-five male goat kids (20±2.5 kg BW) were used during an 84- day experimental period to determine the effect of source and level of sulfur supplementation on mohair characteristics and performance. Experimental diets were diets containing 0.18% (as control), 0.24% and 0.34% DM inorganic or organic sulfur. The data were analyzed as a 2 × 2 factorial design. Methionine ...

Introduction: Previous mastectomy remains a contraindication to SLNB as normal drainage patterns of the breast can be disturbed. Patients diagnosed with DCIS on core biopsy and later found to have microinvasive or invasive carcinoma at the time of mastectomy are deprived of the opportunity for SLNB and need to undergo axillary dissection. We explored the option and feasibility of performing SLN...

RATIONALE Sulfur mustard (SM) is a frequently used chemical warfare agent, even in modern history. SM inhalation causes significant respiratory tract injury, with early complications due to airway obstructive bronchial casts, akin to those seen after smoke inhalation and in single-ventricle physiology. This process with SM is poorly understood because animal models are unavailable. OBJECTIVES...

Sulfur mustard (HD) has been shown to cause a concentration-dependent decrease in viability of human lymphocytes in vitro as measured by dye exclusion; this decrease is preventable by inhibitors of poly(adenosine diphosphatase ribose) polymerase such as niacinamide. The present study investigates the morphologic correlates of the protection afforded by niacinamide through scanning and transmiss...

BACKGROUND The purpose of this report is to examine the viability and safety of preoperative lymphoscintigraphy and radio guided sentinel lymph node (SLN) biopsy for conjunctival melanoma, and to identify the best technique to perform this procedure. METHODS Three patients diagnosed with malignant melanoma of the conjunctiva underwent lymphoscintigraphy and SLN biopsy using a dual technique c...

in order to determine the effect of different levels of sulfur bentonite on yield and yield components of canola a factorial experiment was conducted on the basis of randomized complete block design with three replications in mashhad in 2009-2010 growing season. factors included four levels of sulfur bentonite (0, 300, 400 and 500 kg.h-1) and two varieties of canola (modena and zarfam). the res...

Background: Studies suggest that sulfur may react with plants or monocellular organisms, such as fungi, to produce toxic agents. It has been theorized that sulfur enters cells and affects their respiration. This study reports on a phototroph development that leads to the diminution and/or production of sulfur and release of hydrogen sulfide from public ponds. Methods: This study was conducted ...
