Majorana neutrinos would have the property that the neutrino and antineutrino could be distinguished only by chirality; what experiments observe as a difference between the neutrino and antineutrino could simply be due to one particle with two possible chiralities. As of 2019, it is not known whether neutrinos are Majorana or Dirac particles ...
All plasma proteins except Gamma-globulins are synthesised in the liver. [1] Human serum albumin, osmolyte and carrier protein; α-fetoprotein, the fetal counterpart of serum albumin; Soluble plasma fibronectin, forming a blood clot that stops bleeding; C-reactive protein, opsonin on microbes, [2] acute phase protein; Various other globulins
A method that allows to further narrow the energy distribution of the produced neutrinos is the usage of the so-called off-axis beam. [6] The accelerator neutrino beam is a wide beam that has no clear boundaries, because the neutrinos in it do not move in parallel, but have a certain angular distribution.
The electron neutrino ( ν e) is an elementary particle which has zero electric charge and a spin of 1 ⁄ 2.Together with the electron, it forms the first generation of leptons, hence the name electron neutrino.
Neutrinos produced in nuclear reactors have energies similar to solar neutrinos, of around a few MeV. The baselines of these experiments have ranged from tens of meters to over 100 km (parameter θ 12). Mikaelyan and Sinev proposed to use two identical detectors to cancel systematic uncertainties in reactor experiment to measure the parameter ...
The active neutrinos of the Standard Model, having very low mass (and therefore very high speeds) are therefore unlikely to account for all dark matter. [18] Since no bounds on the mass of sterile neutrinos are known, the possibility that the sterile neutrino is dark matter has not yet been ruled out, as it has for active neutrinos.
Neutrinos, the lightest of the known subatomic particles, lack measurable electromagnetic properties and interact only via the weak nuclear force when ignoring gravity. Matter is virtually transparent to neutrinos and consequently they travel, unimpeded, at near light speed through the Earth from their point of emission.
A recent study showed that activation of HIF-1α allows cardiomyocytes to sustain mitochondrial membrane potential during anoxic stress by utilizing fumarate produced by adenylosuccinate lyase as an alternate terminal electron acceptor in place of oxygen. This mechanism should help provide protection in the ischemic heart. [8]
