The main problem of photographing stained glass windows is setting the correct exposure. An overall average exposure setting frequently results in the highlight areas being overexposed, or dark area being under-exposed, or both. It is therefore necessary to provide a suitable set of image processing tools to correct the image defects. In this work describe several algorithms to solve this probl...

OBJECTIVE To determine whether the correlation between the mean change in disease activity and the mean change in synovial sublining (sl) CD68 expression could be demonstrated across different academic centers. METHODS Synovial biopsies obtained at arthroscopy from patients with rheumatoid arthritis before and 160 days after rituximab therapy were selected and coded. Paired sections were proc...

To clarify the anatomical organization that allows for the synergy of vasopressin and oxytocin with corticotropin-releasing factor (CRF) in promoting adrenocorticotropic hormone secretion from the anterior pituitary, immunohistochemical double staining methods were used to compare the distribution of these peptides in the hypothalamic paraventricular nucleus of normal, colchicine-treated, and a...

Phlebotominae sand fly specimens were prepared for histological and physiological studies. Different fixatives were tested on sectioned and whole bodied adult females in order to obtain good fixation and provide satisfactory penetration of the embedding media. All fixed specimens were infiltrated (up to seven days under 5 C) and embedded in hydroxyethyl metacrylate. Two-three m sections were s...

PURPOSE To evaluate the shade reproduction of a pressable all-ceramic system placed on unstained and stained extracted maxillary central incisor using a color measurement spectrophotometer. In addition, to compare shade reproduction of this material with low translucency and medium opacity on unstained tooth and medium and high opacity on stained tooth. MATERIALS AND METHODS Total 45 discs, w...

Aim: The purpose of this study was to assess whether the intrapartum amnioinfusion (AI) in the presence of meconium-stained amniotic fluid (MSAF) influence the rate of cesarean section and perinatal outcome. Material and methods: The investigated group consisted of 405 pregnant women in labor with meconium-stained amniotic fluid: 163 had performed AI, and 242 constituted a control group (withou...

Gene expression images are of great interest to the biology community, whose databases are growing by leaps and bounds. Indexing and retrieval of these images become extremely necessary as the size of the databases increase. We consider one such problem here – given an embryonic image stained for gene expression, can we classify them into stages corresponding to the developmental morphology of ...

The monoclonal antibody Cat-301 was used to examine neurons in the cerebral cortex and dorsal thalamus of several mammalian species, including Old World monkeys, cats, bush babies, guinea pigs, and rats. In each species, subpopulations of cortical and thalamic neurons are stained along the surfaces of their somata and proximal dendrites. Cat-301-positive cortical neurons include specific groups...

BACKGROUND Cytomegalovirus (CMV) infection can be asymptomatic in healthy individuals but may cause serious complications in immunocompromised patients. We investigated the clinicopathological correlation of CMV in gastrointestinal (GI) biopsies at our institute between January 1, 2013 and December 31, 2015. METHODS A total of 105 non-neoplastic GI biopsies tested positive for CMV by immunohi...
