Conventional video-based system for measuring the subtask speed of the Timed Up and Go Test in older adults: Validity and reliability study.

The Timed Up and Go Test (TUG) is a simple fall risk screening test that covers basic functional movement; thus, quantifying the subtask movement ability may provide a clinical utility. The video-based system allows individual's movement characteristics assessment. This study aimed to investigate the concurrent validity and test-retest reliability of the video-based system for assessing the movement speed of TUG subtasks among older adults.

Reliability and validity of the Swaymeter for measuring the trunk control in children with spastic cerebral palsy.

Aims: To examine the reliability and validity of a simple device, the Swaymeter, for measuring trunk control in children with CP.

Methods: Twenty children with spastic CP participated in this study. Trunk sway was measured while quietly sitting for 30s.

The validity and reliability of the Swaymeter for postural sway measurement in typically developing children aged between 7-12 years.

Background: The Swaymeter is a simple devicefor measuring postural sway. It consists of a 40-cm-long rod with a vertically mounted pen at the end of the rod that measures the displacement of the body at waist level.

Research Question: This device could be an effective tool for measuring postural sway in children.

Melatonin attenuates the mitochondrial translocation of mitochondrial fission proteins and Bax, cytosolic calcium overload and cell death in methamphetamine-induced toxicity in neuroblastoma SH-SY5Y cells.

Methamphetamine (METH) is an addictive drug that can cause toxicity and degeneration in the brain. Several pieces of evidence have demonstrated that METH toxicity results in increases in oxidative stress that regulate an intracellular signaling cascade that leads to cell death. Recently, several studies have emphasized that the overload of cytosolic calcium levels and mitochondrial fission into a small mitochondrial structure is involved in cell death processes.

Melatonin attenuates methamphetamine-induced disturbances in mitochondrial dynamics and degeneration in neuroblastoma SH-SY5Y cells.

Methamphetamine (METH) is a psychostimulant drug that can cause toxicity and degeneration in the brain. The toxicity due to METH involves multiple pathways, including the mitochondrial-dependent death pathway. Several pieces of evidence have emphasized that the fragmentation of mitochondria into smaller structures plays some role in the cell-death process.
