son with that for saline irrigation. METHODS: This retrospective study included 117 consecutive patients (95 women, mean age 51.5 ± 11.4 year) who underwent microvascular decompression for hemifacial spasm. During surgery, BAEPs were monitored to avoid damage to the auditory pathways. When a delayed latency of >1 ms or a decrease in amplitude of >50% was detected in BAEP wave V, surgical maneuvers were halted, and the operative field was irrigated with saline or aCSF. Saline was used for irrigation in 58 patients and aCSF in the other 59. The time required for BAEP recovery at the first halt in each patient was analyzed, and the results were compared between the groups. RESULTS: Surgical procedures were interrupted because of BAEP latency delays or decreases in amplitude in 51 of the patients in the saline group and 54 in the aCSF group. In both groups, the latencies and amplitudes recovered significantly with time and both recovered earlier after aCSF irrigation than after saline irrigation. Hearing outcome was not significantly different between 2 groups. CONCLUSION: aCSF is effective for protection of cochlear nerve and promotes recovery from transient dysfunction during surgery. The protective effect may be attributed to multiple factors including conditioned pH, electrolyte composition, glucose, and microelements, such as magnesium and phosphate....

Psychoactive benzofurans, also known as benzo fury, are new psychoactive substances (NPS) belonging to the phenethylamine family, one of the most numerous NPS groups. These substances share a structural similarity with the classical entactogen...

Artificial cerebrospinal fluid (aCSF)

Artificial cerebrospinal fluid (aCSF) is commonly used when sampling from brain interstitial fluid. This solution closely matches the electrolyte concentrations of CSF.

The effect of irrigation with artificial cerebrospinal fluid (CSF) containing various magnesium ion (Mg2+) concentrations on vasospastic arteries was investigated in the dog. Cerebral vasospasm was induced by the experimental subarachnoid hemorrhage ...

To compare the benefits of physiological saline solution and artificial cerebrospinal fluid (CSF) as perfusates, we investigated 12 patients with presumed symptomatic aqueductal stenosis by clinical course and CSF analysis. In all patients, endoneurosurgical third ventriculostomy and cine magnetic r …

Artificial cerebrospinal fluid (aCSF) is commonly used when sampling from brain interstitial fluid. This solution closely matches the electrolyte concentrations of CSF. It is prepared from high purity water and analytical grade reagents.

5-APB, commonly marketed as 'benzofury' is a new psychoactive substance and erstwhile 'legal high' which has been implicated in 10 recent drug-related deaths in the UK. This drug was available on the internet and in 'head shops' and was one of the most commonly sold legal highs up until its recent U …

What are Phase Change Materials? Thermal Interface Phase Change Materials are used to enhance thermal transfer between a hot component and a thermal solution like a heatsink.  This enables the component to run at a lower temperature whereby increase speed and extending life.  Phase Change Materials are used in the most demanding application across many industry segments.  These include consumer electronics, telecom/datacom, automotive electronics, industrial electronics, medical and military/aerospace. How do Phase Change Materials Work? The first PCMs melted to a liquid state at temperatures between 50C-60C.  This “phase change” allowed the material to wet the mating surfaces, and flow to a minimum bond line to provide the lowest possible thermal resistance, the best performance.  Today most PCMs do not change state (melt) but soften at operating temperatures in the 50C to 70C range whereby providing the same advantages of wetting and minimum bond line but further provide much better long-term reliability (more resistant to pump out) than earlier materials that truly phase change to liquid.   PCMs are generally used in constant pressure application (with some type of spring loaded heatsink). Characteristics and Functions: Thermal conductivity range: 1 – 8 W/mK Thickness range: 0.125mm to 0.5mm Compliancy: UL 94V0, RoHs, REACH Easy to use; peel and stick format with top tabbed liners or automatable placement Laird’s Phase Change Materials Laird PCMs provide industry leading thermal performance, reliability and easy of use all at competitive prices Download our Thermal Interface Solutions brochure. In 2019 we launched fully automated application capabilities for thermal pads and dispensables. You can end manual tasks through automation.

Phase Change Material (PCM) Heat sinks provide significant temporary thermal energy storage in an increasing number of military and commercial applications. ...
