I’m a PhD student in biomedical science in Ukraine. I’m particularly interested in the gut-brain axis and cell death.

@SimonHoiberg Maybe cheaper, but not free. I mean, you have to buy a computer, stuff for hosting Git, and so on.

@parmita @Precigenetics Do this approach work with 3d models?

[Roman Koval @Dr_Bat98]

@parmita @Precigenetics Impressive

@ATinyGreenCell Solid lab, clean and productive. Hope you're doing well. Have you ever bought second-hand equipment? If so, could you share where you bought them?

[Roman Koval @Dr_Bat98]

@J_Cell_Sci I am deeply interested in what those dark small particles that move are.

[Roman Koval @Dr_Bat98]

@Nature Unfortunately, it cannot be used in biomedical research. Maybe I'm doing something wrong, but it also doesn’t work with my coding project related to biomedical research.

@parmita Hello, I am deeply interested in label-free imaging. Maybe you could share some interesting papers or resources with me? Thanks very much.

@rust_ruslan Hello, I am deeply interested in label-free imaging. Maybe you could share some interesting papers or resources with me? Thanks very much.

[Roman Koval @Dr_Bat98]

@precigenetics I am deeply interested in how yours, as I understand it, label-free imaging would deal with 3D models.

@drkeithsiau As a general concept, the ability to do so is great, but it is dangerous in that the immotile sperm is immotile for a reason.

[Roman Koval @Dr_Bat98]

@SethSHowes The ability to do this at a relatively small cost is just insane.

Magnification reduce brightness, so during live cell imaging, the magnification should be lower as possible, with present of minor details that crucial for your scientific question.

In order to reduce phototoxicity and photobleaching in live samples, the light intensity and exposure time should be minimised. However, reducing light exposure leads to a lower signal-to-noise ratio and signal-to-background ratio. #live_cell_imaging
