In the germinal center early stage antibody-secreting B cells undergo isotype switching and transition into a plasma cell. Antibody production by B cells can quickly neutralize a potential infection. Once the infection is neutralized, B cells can become memory B cells, which exist in small numbers...

Waste While the efficient use of CAM can significantly reduce wastage, it does not guarantee minimal leftovers. A lot of it comes down to product design. If the product models are not optimal, it may actually cause the wastage of expensive resources. ...
What does the vacuole do? A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small andhelp sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell. ...
How does it work? Artificial insemination consists of depositing a previously processed semen sample inside the uterus. To carry it out, the specialist introduces a cannula into the uterine cavity transvaginally and in an ultrasound-guided manner, that is to say, controlled by ultrasound. It is...
