Purpose To evaluate if the dose equivalent to 2 Gy per fraction (EQD2)(α/β=3Gy) at 0.1 cm3, 1 cm3, and 2 cm3 of vagina in vaginal-cuff-brachytherapy (VBT) (high-dose-rate [HDR] 192Ir-source) ± external-beam-irradiation (EBRT) is associated with toxicity in post-operative endometrial carcinoma (P-EC). Material and methods From June 2014 till November 2015, 67 consecutive P-EC patients underwen...

BACKGROUND Tea and coffee are the potentially rich source of oxalic acid, which can act as a antinutrient. OBJECTIVE The aim of this study was to determine and evaluate the content of soluble oxalates in teas and coffees available on the Polish market. MATERIAL AND METHOD The green, red and black teas, and black natural ground and instant coffees were used for preparing the infusions. The m...

UNLABELLED Acoustic rhinometry is routinely used for the evaluation of nasal patency. OBJECTIVE To investigate whether the technique is able to identify the impairment of velopharyngeal (VP) activity in individuals with clinical diagnosis of velopharyngeal insufficiency (VPI). METHODS Twenty subjects with repaired cleft palate and inadequate velopharyngeal function (IVF) and 18 non-cleft co...

INTRODUCTION As part of French residents' radiotherapy training, delineation workstations were available at a national teaching course. We report a prospective comparative study of a non small cell lung cancer (NSCLC) case delineated by 120 residents before and after a radioanatomy/radiotherapy lecture. MATERIALS AND METHODS The case of a patient with right upper lobe non small cell lung canc...

Inhalation toxicology studies with chrysotile asbestos have in the past been performed at exceedingly high doses without consideration of fiber number or dimensions. As such, the exposures have exceeded lung overload levels, making quantitative assessment of these studies difficult if not impossible. To assess the cellular and pathological response in the rat lung to a well-characterized aeroso...

4-Methyl-3-heptanone (0.59 pg/head) and 2-heptanone (0.1 4 pg/ head) are the main volatile components of the mandibular glands of major workers. In the laboratory, worker ants detected and were attracted by 4-methyl-3-heptanone at a concentration of 5.7 x 10-l3 g/cm3 (2.7 x lo7 molecules/cm3). They were alarmed by a concentration of 5.7 x 10-la g/cm3 (2.7 x 108 molecules/ cm3). 2-Heptanone is l...

Emergency software problems may present an immediate danger to public health, safety, general welfare or business. Hence, the organisations must be well prepared to handle them with the greatest expediency. Unfortunately, the software community has paid little attention to the emergency corrective maintenance. Today, we do not have any standard process models for handling emergency situations. ...

The current standard for occupational exposure to asbestos is 2 fibers/cm3 averaged over an 8-hr day. A NIOSH/OSHA committee has recently concluded that the 2 fiber/cm3 standard is grossly inadequate to protect workers from asbestos-related disease, and that all levels of asbestos exposure studied thus far have demonstrated asbestos-related disease. The committee recommends that a 0.1 fiber/cm3...

Background: Due to the current trends towards replacing axillary dissection with radiotherapy, the need for more precise definition for different nodal stations becomes a must to ensure safe and adequate dose coverage. So, our study aimed to evaluate the coverage of axillary nodal volumes based on Project on Cancer of the Breast (PROCAB) guidelines, for cases previously treated with our standar...
