What is Histology?

Histology is the study of tissues and cells, looking in depth at the fine details revealed by optical microscopes. The optical microscope is able to examine specially prepared samples of plant or animal tissue, most usually to up to a maximum magnification of x1500. Samples of cells will be specially prepared, to produce a thin layer of material which might be stained to reveal specific structures or materials. Optical microscopes have been available since around 1620, although the very first were more of a novelty item, providing a low magnification and a rather blurry image. Over time the technical specification of the microscope has been increased to the high resolution equipment available to the modern scientist.

For most people, the first experience of microscopy is in the classroom, using fairly basic equipment, but this gives us all an indication of the amazing microscopic world around us and allows us to begin to think at the microscopic level. The fact that we can see cellular structures in detail allows us to begin to think about how cells and, ultimately, the wide range of plants and animals in the world, actually work.

So histology is widely used in scientific fields, becoming an essential tool in biology, medicine and veterinary sciences.

In education, histology is used to show the normal structure of cells of plants and animals and to underpin the understanding of the fundamental processes of living creatures: movement, reproduction, sensitivity, nutrition, excretion, respiration and growth. By examining the cell structures in depth the scientist is able to develop an understanding of the chemical and biological processes that are taking place at a cellular level. They can come to understand the way to form of the cell follows the function the cell, and how the cell is specialised to do a specific job within the body.

It is a key aspect of the diagnosis of disease, with the analysis of tissue samples being a vital part of many diagnostic processes. Histopathology, the study of diseased tissues, is a significant area of study and essential to this process. This process is most usually undertaken in a Pathology Laboratory, the domain of the Clinical Pathologist, a medical specialist concerned with the diagnosis of disease. It is to the Pathology Lab that the samples taken in a doctor’s surgery, or at a hospital, are sent for analysis.

Forensic science also employs microbiological techniques of tissue analysis and comparison along with the study and comparison of inanimate structures such as fabric fibres, soil and pain samples and so on. This is a highly specialised area where the skills of the scientist must be used alongside the considerations of legal demands around criminal procedure and admissible evidence.

The process of autopsy, the analysis of post mortem remains, will often also include the microbiological study of tissues and tissue structures, aiding the process of understanding the cause of a death.

Finally forensic archaeologists will use microscopic analysis of tissues to gain understanding of the lives of individuals living many hundreds of years ago.

Microscopes have opened the door to understanding the way the cells of plants and animals are structured and function, expanding the horizon for scientists each and every day. You can find a wide range of Microscopes at http://mazurekopticalservices.co.uk/

Ludovic Biyong



Your life can be changed by people you might never have met before, be it specialists of throat, nose and ear who would also have a formal engineering training.
Ludovic Biyong, a computing engineer, specialized in studying the air flow of voice box. Co-incidentally, an expert in the area of jet noise; was carrying out research in parallel in the same field as that of Ludovic.
They decided to collaborate for the better benefit of people. Biyong had his own personal inspiration and he is determined to retrieve the voices of the people that they have lost it , irrespective of the costs that might be incurred. Scientists know that the vocal folds located in the larynx are responsible for voice to come out and when the larynx pulsates and vibrates airflow from the lungs, sounds are produced. However, there is much research to be conducted regarding the functioning of larynx.
The sound vocal cords produce are researched to a great extent. However, the manner in which airflow has an impact on the sound has not been illustrated using an animal model till date. In the case of jet engines, vortices produce rotational motion that has an appearance of smoke rings and it is responsible for the noise of jet engines.
Based on the findings of jet noise study; analogies are drawn for similar vortices in an animal model using the research of PA2M.
Ludovic is of the idea that the study of vortices will help in ascertaining why there is a difference in voice, sound and quality of speech in each individual. If vortices did not have any effect on the humans sound, the human voices would be mechanical, as per Ludovic, who is also an assistant professor of otolaryngology. Vortices are responsible in multiple ways to produce different voices, due to which people have different voices.
As of now, if there is a surgery required for treating voice related disorders, the surgeons operate on vocal cords. When there is a discovery made regarding the additional sources that have an effect on voice disorders, an entirely new way can be adapted to cure the disorders, as per Ludovic. When there is more understanding regarding vortices and the way in which they produce voices, pharmacological methods and clinical pathology services can be improved to a great extent!
