A comprehensive understanding of intercellular and cell-matrix interactions is essential for advancing our knowledge of cell biology. Existing techniques, such as fluorescence microscopy and electron microscopy, face limitations in resolution and sample preparation. Supravital lanthanoid staining provides new opportunities for detailed visualization of cellular metabolism and intercellular interactions.

- Standard culture methods for diagnosing infections typically use a temperature of 37 °C, but microorganisms on the ocular surface during infectious keratitis may grow better at different temperatures due to unique heat exchange features of the eye.
- This study looked at microorganisms isolated from patients with infectious keratitis and healthy controls by growing them at both 37 °C and 24 °C, employing various identification techniques.
- Findings revealed that certain microorganisms known as psychrotolerant can grow at lower temperatures (24 °C) and could play a role in infectious keratitis, highlighting the importance of considering temperature differences in diagnosis and treatment.
Was to assess the possibility of using chemical analysis of bone mineral content by the means of an energy dispersive X-Ray spectroscopy to determine the age of unidentified corpses for forensic identification. A semi-quantative chemical microanalysis of bone fragments of 85 male and female corpses aged between 21 and 91 was done through the use of energy dispersive X-Ray spectrometer. The association of bone tissue apatite mineral composition with age is confirmed and a formula, connecting age and chemical composition change, is proposed.

- The review outlines the historical development of new chemical reagents that enhance the use of scanning electron microscopy (SEM) in medical and biological research, especially in ophthalmology.
- It addresses the challenges of applying SEM in clinical medicine, particularly in preparing biological samples for analysis.
- The article also highlights practical examples of SEM's application in clinical ophthalmology and discusses its future potential, especially with the integration of artificial intelligence in diagnostic processes.
Purpose: This study provides a detailed analysis of the bioinorganic chemical composition of lens substance in patients with senile cataract using classical and spatial statistics methods.
Material And Methods: The study included 30 isolated human lenses. The light scattering ability (LSA) of the lens substance was evaluated using an original method.
