DISLOCATION OF THE KNEE AND DISLOCATION OF THE FOOT [PDF]

Journal of the American Medical Association, 1909
A case of anterior dislocation of the knee and a case of backward subastragaloid dislocation of the foot with fracture of the astragalus were both seen at the Baltimore City Hospital in the service of Dr. A. C. Harrison, and are reported because of the rarity of the conditions. Dislocations of the knee compose less than 2 per cent. of all dislocations.

The study of plastic deformation in the crack surrounding in AZ61 alloy [PDF]

FME Transactions, 2013
This paper deals with the study of effect of microstructure on the development of plastic deformation around the propagating cracks of the magnesium alloy whose corrosion resistance is increased by the addition of 0.5 wt. % Ca.

An investigation on the precipitates in T5 treated high vacuum die-casting AE44–2 magnesium alloy

Materials Research Express, 2022
The AE44-2 magnesium alloy was fabricated via die-casting under high vacuum (denoted as HVDC-AE44-2 alloy). The microstructures and mechanical properties of the aged HVDC-AE44-2 alloys were investigated.

Vortex pinning by natural defects in thin films of YBa2Cu3O7−δ [PDF]

, 2002
Although vortex pinning in laser-ablated YBa2Cu3O7−δ films on (100) SrTiO3 is dominated by threading dislocations, many other natural pinning sites are present.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Dislocation Behavior in TiVTa Multi-Principal Element Alloys: A Nanoindentation Simulation Study

Crystals
Molecular dynamics simulations of nanoindentation were conducted to compare the dislocation behavior in a pure V and a TiVTa multi-principal element alloy (MPEA) with [100] and [111] crystal orientations.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
