Tourniquet and/or Adductor Canal Block Use Confer No Additional Early Quadriceps Weakness Following Total Knee Arthroplasty: An Analysis of 203 Patients.

Background: Quadriceps weakness following total knee arthroplasty (TKA) delays rehabilitation and increases fall risk. The combined impact of tourniquets and adductor canal blocks (ACBs) on postoperative quadriceps strength has not been defined. This study evaluated the early effects of tourniquet and/or ACB usage on quadriceps strength following TKA.

The Cwr1 protein kinase localizes to the plasma membrane and mediates resistance to cell wall stress in .

Unlabelled: The plasma membrane is critical for the virulence of the human fungal pathogen . In addition to functioning as a protective barrier, the plasma membrane plays dynamic roles in a wide range of functions needed for virulence including nutrient uptake, cell wall synthesis, morphogenesis, resistance to stress, and invasive hyphal growth. Screening a collection of mutants identified an understudied gene that is important for invasive hyphal growth, which we have termed (Cell Wall Regulatory kinase).

Candida albicans pathways that protect against organic peroxides and lipid peroxidation.

Human fungal pathogens must survive diverse reactive oxygen species (ROS) produced by host immune cells that can oxidize a range of cellular molecules including proteins, lipids, and DNA. Formation of lipid radicals can be especially damaging, as it leads to a chain reaction of lipid peroxidation that causes widespread damage to the plasma membrane. Most previous studies on antioxidant pathways in fungal pathogens have been conducted with hydrogen peroxide, so the pathways used to combat organic peroxides and lipid peroxidation are not well understood.

Sur7 mediates a novel pathway for PIP regulation in that promotes stress resistance and cell wall morphogenesis.

The human fungal pathogen can cause lethal systemic infections due to its ability to resist stress from the host and to undergo invasive hyphal growth. Previous studies showed that plasma membrane MCC/eisosome domains were important for virulence by promoting the ability of Sur7 to mediate normal cell wall morphogenesis and stress resistance. The mutant displayed abnormal clusters of PIP, suggesting that misregulation of this lipid underlies the phenotype.

Vascularized tumor-on-chip microplatforms for the studies of neovasculature as hope for more effective cancer treatments.

Angiogenesis is the development of new blood vessels from pre-existing vasculature. Multiple factors control its course. Disorders of the distribution of angiogenic agents are responsible for development of solid tumors and its metastases.
