Hand test as an instrument for the prediction of aggressive behavior

The hand test it's a personality projective test. It uses ten plates, nine of which represent a hand in different positions: the plates are shown one by one, successively, and the subject is asked to express his interpretation on the activity of the hand shown there. Confronted with the tenth plate, which is white, the subject, instead, must imagine a hand and tell what it is doing; The answers are recorded together with the time of reaction and any other meaningful behaviour, then the score is computed and the interpretation is made, according to the prescribed procedures. Among the different aims pursued by this test, the first one to be reached was the forecase of aggressive behaviour. The quantitative evaluation of the probability that the subject considered could, in the future, act aggressively, is provided by the acting out score. The principle, on which is based the determination of this score, is that the probability of an exterior aggressive behaviour increases in the same way as the dominant and aggressive attitudes prevail on the attitudes for social cooperation. Grouping, then, the answers which show tendencies of the two kinds and calculating the algebraical difference between the two groups, the acting out score ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
