Neutral lipids regulate amphipathic helix affinity for model lipid droplets.

J Cell Biol 2020 04;219(4)

Laboratoire de Physique de l'Ecole Normale Supérieure, ENS, Université PSL, Centre National de la Recherche Scientifique, Sorbonne Université, Université de Paris, Paris, France.

Cellular lipid droplets (LDs) have a neutral lipid core shielded from the aqueous environment by a phospholipid monolayer containing proteins. These proteins define the biological functions of LDs, and most of them bear amphipathic helices (AH), which can selectively target to LDs, or to LD subsets. How such binding preference happens remains poorly understood. Read More

Lipid droplets fusion in adipocyte differentiated 3T3-L1 cells: a Monte Carlo simulation.

Exp Cell Res 2014 Feb 3;321(2):201-8. Epub 2014 Jan 3.

Department of Neurological and Movement Sciences, University of Verona, Strada Le Grazie 8, 37134 Verona, Italy.

Several human worldwide diseases like obesity, type 2 diabetes, hepatic steatosis, atherosclerosis and other metabolic pathologies are related to the excessive accumulation of lipids in cells. Lipids accumulate in spherical cellular inclusions called lipid droplets (LDs) whose sizes range from fraction to one hundred of micrometers in adipocytes. It has been suggested that LDs can grow in size due to a fusion process by which a larger LD is obtained with spherical shape and volume equal to the sum of the progenitors' ones. Read More

Supporting medical students with learning disabilities in Asian medical schools.

Adv Med Educ Pract 2010 7;1:31-9. Epub 2010 Oct 7.

Department of Clinical Sciences, School of Life Sciences, University of Bradford, West Yorkshire, Bradford, UK.

Learning disabilities (LDs) represent the largest group of disabilities in higher education (HE) institutes, including medical schools, and the numbers are continuing to rise. The worrying concern is that two-thirds to half of these students with LDs remain undiagnosed when they start their undergraduate education and may even graduate without having their disabilities diagnosed. These students struggle with their academic abilities, receive poor grades and, as a result, develop lower perceptions of their intellectual abilities than do those students without LDs. Read More

Cocaine addicts and their families. An empirical study of the processes of identification.

Int J Psychoanal 2001 Apr;82(Pt 2):347-60

The processes of identification between adolescent cocaine addicts and their parents were studied in 402 subjects, in total 134 familial triads (father-mother-son), subdivided into two groups of 67 triads, one of these groups having as the child an adolescent of masculine sex dependent on cocaine and the other, equal in number, being a control group, duly matched for age and socio-economic status. The instrument employed was the Rorschach test (1922), limited to the application of the Lerner Defense Scale (LDS; Lerner & Lerner, 1980). The findings in the affected triads showed up as consistent statistically for the presence of intense processes of pathological identification, especially between father and son, a sign of the importance of the presence of disturbances of paternal function in the development of this addiction.
