Summary
Vitrectomy size impacts lymphoma cell survival, with larger gauges improving outcomes. This finding offers guidance for diagnosing suspected lymphoma cases using specific surgical instruments.
Area of Science:
- Ophthalmology
- Oncology
- Cell Biology
Background:
- Diagnostic vitrectomy is crucial for evaluating ocular conditions.
- Understanding factors affecting cell survival during vitrectomy is essential for accurate diagnosis.
Purpose of the Study:
- To investigate the impact of vitrectomy size and cutting rate on healthy lymphocyte and lymphoma cell survival.
- To establish an in vitro model for assessing cell viability post-vitrectomy.
Main Methods:
- Healthy lymphocytes and lymphoma cells were subjected to vitrectomy using varying gauge sizes (20G-27G) and cutting rates.
- Cell integrity was analyzed using fluorescence-activated cell sorting (FACS).
- Statistical analysis was performed using the Kruskal-Wallis test.
Main Results:
- No significant correlation was found between vitrectomy size/cutting rate and healthy lymphocyte survival.
- A significant positive correlation was observed between larger vitrectomy lumen diameter and lymphoma cell survival.
Conclusions:
- Larger vitrectomy lumen diameters are associated with increased lymphoma cell survival.
- The use of 23G and 25G instruments is suggested for clinical practice in suspected lymphoma cases.
- This research provides a guideline for investigating suspected lymphoma.

Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

Solids, liquids, and gases are the three states of matter commonly found on Earth. A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of its container, except it forms a flat or slightly curved upper surface when acted upon by gravity. Both liquid and solid samples have volumes nearly independent of pressure. A gas takes both the shape and volume of its container.

01:13What is Matter?
15.7K
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...
