AMONG the complications that may plague the patient with myocardial infarction, there are few more dramatic or serious than rupture through an infarct involving the interventricular septum.

Our collection of antimatter has just gotten heavier, as researchers have logged the heaviest antimatter version of an atomic nucleus yet, called antihyperhydrogen-4. “We didn’t think that it ...

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus ...

The first step in the process of generating embryonic stem cells is to remove the nucleus from an unfertilized egg cell (A). Because the egg cell is only 100 micrometers, or one-tenth of a ...

The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major ...

Being born preterm is a known major risk factor for life-changing brain injury, but there is still a lot to understand about exactly what occurs inside these tiny babies that can do so much damage ...

With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's.

Messe SR, Silverman IE, Kizer JR, et al. Practice parameter: recurrent stroke with patent foramen ovale and atrial septal aneurysm: report of the Quality Standards Subcommittee of the American ...

Question: when is a strong force not a strong force? Answer: when it’s anywhere outside the atomic nucleus. That at least is the case with the strong nuclear force, one of four fundamental ...

A patent foramen ovale or PFO is a defect in the wall between the two upper chambers of the heart. This defect is actually an incomplete closure of the atrial wall that results in a flap or valve-like ...

Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found in both animal and plant cells. All life on ...

Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.
