AI Thread Summary
Isotonic solutions are defined by their osmolarity, typically around 300 mOsm, but their specific compositions can vary significantly based on application and context. In the case of in vitro fertilization and oocyte culture, while the osmolarity is crucial, the exact ionic composition (such as sodium, potassium, and chloride levels) may differ. This variability arises from historical practices, regional standards, and specific research requirements. For accurate application, consulting primary research literature and comparing standards from different national bodies is essential, as modern standards are increasingly global.

Question is simple my friends.Our using all of isotonic solution's specs are same or different each other ?
 
Biology news on Phys.org
AFAIK, 'isotonic' simply means the solution has about 300 mOsm of solute. I don't know if it additionally requires (for example) 140 mM Na, 5 mM K, 100 mM Cl, etc. etc. What is your application?

in vitro fertilisation - I'm researching for oocyte culture, ı found its specs but I'm curioused for all cells isotonic cultures have the same specs? They r in blood and need to be blood's Osm. isn't it ?
 
No. "isotonic solution" has different meanings/composition depending on history, location and use. Sorry, I'm not more specific, but the primary research literature should have details (and comparison of various national bodies standards will also show differences). (more modern standards will tend to be more global, of course).

https://www.nhs.uk/mental-health/conditions/body-dysmorphia/ Most people have some mild apprehension about their body, such as one thinks their nose is too big, hair too straight or curvy.

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
