aleb measure?
Question 6 options:

period


frequency

wavelength


The types of waves: mechanical and electromagnetic. Microwaves, Infrared waves, and radio waves are examples of electromagnetic waves. Which statement is true about the speed of an electromagnetic wave?

Question 7 options:

It is not affected by changes in media.


It is slower in a vacuum than in a medium.


In a vacuum, its speed equals half the speed of light.


It slows down when it goes from a vacuum to a medium

How to get high affinity antibody?
Anit [1.1K]

Human monoclonal antibody (mAbs) are emerging in the field of cancer therapy and have become an increasing proportion of new drugs that are recently approved. Although there are some methods to obtain antigen-specific mAbs from human B cells, it is generally impossible to directly immunize human beings with antigens of interest. For example, for infectious agents, those approaches are largely restricted. To solve these obstacles, two main approaches have been developed; either by humanizing antigen-specific antibodies from small experimental animals (which is laborious due to the great genetic differences from humans) or rely on the in vitro selection of antigen-specific binders from human antibody repertoires. However, the human mAbs developed by these methods are usually with low affinity.

We are now coming up with a much better idea that is humanizing non-human primates mAbs instead of murine mAbs. Due to the close genetic relationship with humans, immunized NHPs have more potential to be isolated with high affinity antibody to human target than other experimental species, such as mouse, rat and rabbit. In addition, with appropriate method, NHP antibodies are much<span> easier to be humanized</span> without any loss of affinity compared to widely used murine antibodies.

Which of the drugs (if either) was more successful in preventing the recurrence of depression relative to the placebo?
Alex17521 [72]
The results clearly reveal that Imipramine is by far more effective than Lithium in preventing the recurrence of depression. 62.16% of the patients taking Lithium had a recurrence of depression which is more than twice that of patients who took Imipramine (28.95%). 

The results also question the effectiveness of Lithium in general since the percentage of patients who had a recurrence of depression in the Placebo group (67.65%) is only slightly higher than that of the Lithium group (62.16%).
