Histology is the study of animal and plant tissues. Tissues are defined as cells with their ground substance acting together in the performance of a particular function. An organ is an aggregation of tissues that occur and function together to provide a division of labor. Epithelial tissue covers body's surface and most of the inner cavity. It also provides the essential functions of protection; containment of body fluids and transport

Introduction Huntington’s disease is one of many neurodegenerative diseases, which has chorea as one of its prevalent symptoms (Hergert, Sanchez-Ramos, & Cimino, 2019, p.1) . Discovered in the late 1800s’ by George Huntington, a young American medical doctor at the time, the disease has gathered interest from the medical community—but with little in the way of a cure. The disease is highly hereditary, with a 50% chance of transference from parent to

Pathologists are often called 'the doctor's doctor ' -- when other doctors are experiencing an impasse, they go to a pathologist for advice, to provide clarity. As someone who has always enjoyed working as a teacher and preparing teaching materials, I look forward to this role in relation to my fellow physicians. Upon arriving in the United States to practice medicine, I gained experience in the field of pathology-related research,

" (Volpicelli-Daley and Levey, 2003) Prior to visualization of the molecule of interest it is necessary to "fix and section the brain tissue. Double-labeling immunofluorescence is stated to detect "localization of a protein of interest as well as the distribution of the protein relative to another marker such as a neurochemical or organelle marker." (Volpicelli-Daley and Levey, 2003 Fluorescence imaging labeled tissue through use of confocal makes provision of "high-resolution analysis

Thyroid "hot spots" incidentally detected by whole body Fluorodeoxyglucose-Positron Emission Tormography (FDG-PET) scan Fluorodeoxyglucose (FDG) whole body positron emission tormography (PET) scan is being used more often in the diagnostic follow-up or work-up of patients. In such conditions, positive PET scans with unanticipated hot spots within the thyroid region could be given the definition of thyroid FDG-PET incidentaloma, a name analogous to unexpected sonographic thyroid modules. A description of eight consecutive

1993). Using a rigid-tube bronchoscope, the bronchial biopsies were taken under local anaesthesia from two different airway levels: (a) inside the right upper lobe bronchus, and (b) at the opening of the right middle lobe (Laitinen et al. 1993). Preparations of the specimens thereby obtained were completed for light as well as electron microscopy; the researchers also used slot grids 1 x 2 mm which facilitated photography of a large
