OBJECTIVE To evaluate facial soft tissue changes after the use of fixed functional appliances in Class II division 1 malocclusion cases using a systematic review of the literature. MATERIALS AND METHODS Several electronic databases (PubMed, Medline, Medline In-Process & Other Non-Indexed Citations, Cochrane Database, Embase, Web of Sciences, and Lilacs) were searched with the help of a senior...

despite a lot of research, the etiology and progression of breast cancer remain incompletely understood. recently, human cytomegalovirus (hcmv) was reported as a risk factor for breast cancer. the aim of this study was to know whether breast cancer could be caused by cytomegalovirus or not? in this experiment seventeen samples of razi/a mice with spontaneous breast cancer were being gathered fr...

We used formalin-fixed human spinal cord and dorsal root ganglia as immunogens to generate monoclonal antibodies (mAb) which immunohistochemically react with neurons in formalin-fixed human tissue sections. Three of the mAb recognized all neuronal populations studied, including those in spinal cord, dorsal root ganglia, cerebellum, and cerebrum. A fourth mAb recognized neurons within spinal cor...

Recent developments in spatial proteomics have paved the way for retrospective in situ mass spectrometry (MS) analyses of formalin-fixed paraffin-embedded clinical tissue samples. This type of analysis is commonly referred to as matrix-assisted laser desorption/ionization (MALDI) imaging. Recently, formalin-fixed paraffin-embedded MALDI imaging analyses were augmented to allow in situ analyses ...

No neutral lipid, but nearly all the phospholipid, was retained in Acanthamoebae when this organism was fixed in osmium tetroxide and dehydrated with ethanol. If applicable to intestinal mucosa, this observation of Korn and Weisman's (I) might disturb electron microscopists striving to interpret morphological events during fat absorption. Three other groups of investigators have commented on th...

The application of matrix-assisted laser desorption/ionization (MALDI)-based mass spectrometry (MS) to the proteomic analysis of formalin-fixed paraffin-embedded (FFPE) tissue presents significant technical challenges. In situ enzymatic digestion is frequently used to unlock formalin-fixed tissues for analysis, but the results are often unsatisfactory. Here, we report a new, simplified in situ ...

AIMS To investigate the problems involved in undertaking immunohistochemistry (IHC) and nuclear morphometry using Bouin's fixed prostate biopsies. METHODS Archival Bouin's fixed and formalin fixed, paraffin wax embedded prostatic biopsies were immunostained for three nuclear biomarkers (minichromosome maintenance protein 2 (MCM-2), p27, and Ki-67), one membrane localised biomarker (C-erb-B2),...

Two methods are described for the study of adipose tissue cellularity and metabolism. In the first, 8 M urea was used to liberate osmium tetroxide-fixed adipocytes from the connective tissue matrix. In the smaller-sized cell ranges there was a significant reduction in apparent adipocyte number of rat, pig, and beef adipose tissue with 8 M urea treatment. This was attributed to solubilization of...

Previous ex vivo diffusion tensor imaging (DTI) studies on formalin-fixed myocardial tissue assumed that, after some initial changes in the first 48 hr since the start of fixation, DTI parameters remain stable over time. Prolonged preservation of cardiac tissue in formalin prior to imaging has been seen many times in the DTI literature as it is considered orderly. Our objective is to define the...

We investigated the mechanics of the forces within the junction of polyimide insulated stainless steel microelectrode (diameter= 125 um) and auditory cortical interfaces of rat and human brain tissue (1mm and 3.5 mm, respectively). Insertions were performed on formalin fixed human brain (FHB) tissue (10 % formaldehyde) at 5 mm increments from anterior to posterior HG. In formalin fixed rat brai...
