Darkfield illumination is comparable to viewing star or clusters of stars on a dark night. They seem so near in spite of their great distance from the Earth. Sounds appealing? Well, this is due to a dark background in contrast to the sparkling light of the stars. But this magnificent view can only be seen […]

There are many unicellular organisms abounding our planet and their behaviors and reactions are very interesting to study and observe. It should be noted that certain organisms yield benefits but some can be harmful and fatal. It is in this light that many scientists nowadays are continuously studying and observing unicellular or multi-cellular organisms. Dark […]

Dark field light microscopy is a very important tool used in live blood analysis. While the whole concept is rather new, the idea is fast becoming popular today. In fact a handful of experts are already performing it. Understand what live blood analysis is and how it works through the article below.

The principles of dark field microscopy is mostly used in observing cells and tissues. And the key to all of it is to understand what dark field microscopy’s role is in this endeavor and how it had made all the researches possible.
When comparing dark field optics with phase contrast optics, dark field optics are priced […]

The principles behind brightfield/darkfield light microscopy are relatively complex. In essence, they are the concepts that allows the users to have a better view of the specimens that they are observing.

With the advent of clinical radiology and microscopes such as darkfield light microscopes, it became evident that a di¬aphragmatic hernia was a relatively common abnormality and not always accompanied by symptoms. Three types of esophageal hiatal hernia were identified: (1) the sliding hernia, type I, char¬acterized by an upward dislocation of the cardia in the […]

When considering resection, tumors of the esophagus (best diagnosed using specialized medical microscopes or even darkfield light microscopes) are best divided into those above and those below the carina. Czerny reported the first successful resection of a carcinoma of the cervical esoph¬agus in 1877. It was hoped that the prognosis for patients with this disease […]

Accidental caustic lesions occur mainly in children, and in general, rather small quantities of caustics are taken. In adults or teenagers, the swallowing of caustic liquids is usually deliberate, during suicide attempts, and greater quantities are swallowed. Alkalies are more frequently swallowed accidentally than acids, because strong acids cause an immediate burning pain in the […]

Tumors, usually diagnosed using microscopes such as darkfield light microscopes, which arise below the carina, the preference of these authors is either an en bloc resection for cure or a transhiatal removal for palliation. A curative procedure is performed according to the principles of an en bloc resection in continuity with the regional lymph nodes. […]

The development of surveillance programs for the detection of early squamous cell carcinoma in endemic areas using darkfield light microscopes or any other medical microscopes and for early adenocarcinoma in patients with Barren’s esophagus has given rise to controversy over how to manage tumors (diagnosed using a microscope such as a darkfield light microscope) confined […]
