Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are difficult to be detected on CT scan, but easily detected on gradient echo and susceptibility weighted imaging on MRI scan as hypointense susceptibility blooming.
High levels of intracellular Ca 2+, the major cause of post-injury cell damage, [30] destroy mitochondria, [11] and trigger phospholipases and proteolytic enzymes that damage Na+ channels and degrade or alter the cytoskeleton and the axoplasm. [31] [26] Excess Ca 2+ can also lead to damage to the blood–brain barrier and swelling of the brain ...
The Specialist and Warrant Officer Institute (SWI, Chinese: 士官与准尉学院, Malay: Institut Pakar Dan Pegawai Waran, Tamil: நிபுணதது் வ, வாரண் ட் அதிகாரி கழகை்) [2] is the military training centre for warrant officers, specialists (non-commissioned officers) and military experts of the Singapore Armed Forces.
As the Singapore Armed Forces expanded, the School of Infantry Section Leaders (SISL) was established on 1 October 1970 [1] with a 21-week training course for NCOs. In 1979, after the military training system underwent a restructuring, high-performing SISL trainees were selected to undergo further training at the Officer Cadet School to become ...
A mnemonic to remember the warning signs of stroke is FAST (facial droop, arm weakness, speech difficulty, and time to call emergency services), [17] as advocated by the Department of Health (United Kingdom) and the Stroke Association, the American Stroke Association, the National Stroke Association (US), the Los Angeles Prehospital Stroke ...
Images of CAA collected at 1.5 T. Left, conventional T2* (TE=20 ms), center, SWI processed magnitude image (TE=40 ms) and right, SWI phase image (TE=40 ms) Gradient recalled echo (GRE) imaging is the conventional way to detect hemorrhage in CAA , however SWI is a much more sensitive technique that can reveal many micro-hemorrhages that are ...
ARIA-E refers to cerebral edema, involving the breakdown of the tight endothelial junctions of the blood-brain barrier and subsequent accumulation of fluid. [3] In a double-blind trial of the humanised monoclonal antibody solanezumab (n = 2042), sixteen patients (11 taking the drug, 5 taking a placebo), or 0.78% developed ARIA-E.
Preliminary investigations suggested the flight experienced rapid vertical force changes and an altitude drop of around 177 ft (54 m) [9] The flight was then diverted to Bangkok, where it made an emergency landing at 15:45 local time. [10] [5] [6] Singapore Airlines dispatched a relief flight which carried 131 passengers and 12 crew members to ...
