How can multidisciplinary teams improve the care ofpatients with toxic alcohol ingestion?
Hi everybody, I wonder is there a way to prepare foam from iso-propanol/water mixture? The content of this alcohol should be 70 – 80 w.%. I plan to use silicone-based surfactants, I have several of them. What do you think, is this enough to stabilize the foam for sevaral minutes? I plan to use the foam with a typical spray bottle for disinfection of hard to reach metal parts. Issues with human skin compatibility are therefore not an issue. Thanks for your suggestions.
Does anyone have any knowledge about the solubility of a polyacrylic (MW 2100 and 5100) in isopropyl alcohol or DMF?
I was thinking of using DCC/DAMP in dichloromethane. Would this be effective? Also would the byproduct Of DCU precipitate out in this setup?
the alcohol is a primary group and the bromo is a primary bromo on the opposite end of the alcohol
Dear Community,
I have a molecule with an aldehyd group that I want to reduce to the alcohol. The molecule also has two esther groups. When I react the molecule with NaBH4 (1 eq.) under soft conditions (room temperature, 3h) no reduction is taking place, under harsh conditions (heat, over night) also the esther groups are reduced. [Solvent THF in both cases]
Does anyone have a recommendation for suitable reaction conditions for NaBH4 reduction? Or experience with NaBH4 reductions?
Best regards,
Christian
When I use vaspsol calculation in of a alcohol in presence of solvent ( H2O ) that OH bond of alcohol always breaking. What is the reason? I am playing with POTIM, ISMEAR etc. still that problem exists... DO you have any idea why its happening? Or how can I change my INCAR Tags ?
I am working on a grignard reagent(PhMgBr) addition reaction(with alpha,beta unsaturated ketone) and my product is a tertiary alcohol. I have found through Tlc, I had got a mixture.How to purify the mixture,so that I can get a single spot of my product in the Tlc. I am getting my crude product as a viscous liquids. Need suggestion to purify it.
Dmt protection is a important step allowing protection of the hydroxyl group in the 5'OH in the nucleotides. This 5'OH specific protection allow a sequential coupling of the nucleotides, forming a obligonucleotide.
As we know DMT protection is follow the sn1 reaction manner. And for sn1 reaction, primary alcohol is less reactive than the secondary alcohol. Therefore, beside steric hindrance I would like to know why DMT is 5'specific. Thank you so much
is it safe to use for extraction purpose?
I was trying to stain prostate slides with toluidine blue, but I'm having a recurring problem. Some of them seem to be "hollow" and you can only see the contour of the cell, but in the same tissue some areas are normal.
I tried different protocols, but none works right.
Currently I'm using toluidine blue 1% in distilled water. Also used acid toluidine blue (which didn't work at all), and toluidine blue 1% in alcohol mixed with 1% NaCl. For dehydration we use alcohol 95%, alcohol 100% two times, 30s each, alcohol/xylol 1 min, xylol 2 times 1min each.
Did anyone ever get similar results?


Can we use amyl alcohol instead of iso-amyl alcohol (with chloroform) for DNA isolation?
Individuals who consume alcohol are more prone to engaging in violent behavior towards their partners, leading to various negative outcomes. what is the most effective method in preventing alcoholism as the main cause of domestic violence?
What's your suggestion for converting a heavy organic alcohol to its corresponding acid (via oxidation or dehydrogenation)?
Your industrial experience is appreciated.
Other than GC any other method might help.
could you please help with a protocol?
should i do it directly on the aluminium stub after dehydration with 100% alcohol or not?
should i release the pollen or whole anther is better and dehisce it later?
after drying with HMDS how can i keep the specimens on aluminium stub before coating for about 24h?
social consequences of excessive alcohol consumption
I am preparing a protocol for SEM of a biofilm, but do not have easy access to 100% ethanol for the dehydration steps. Can 100% ethanol be substituted for 100% alcohol (95% EtOH, 5% methanol/isopropyl alcohol)? 95% ethanol generally is not anhydrous, and water has enough surface tension to potentially damage the specimen. I am also open to other suggestions if anyone has any. Thank you!!
Greetings all
I have been facing a problem with Technovit 9100. The polymerization never worked with me I have tried multiple times with the (stable and destabilized) basis solution in different conditions, however, I still end up with a liquid form which never hardens.
Tissue type:
- Human acetabular bone with soft tissue attached. Total size: 13*10 mm.
- Human femoral head. Total size 5*5 mm.
Protocol:
1) Dehydration on tissue rocker for (agitation): (50%, 70%, 80%, 95%, 95%) 1 hour each; (abs alcohol) overnight then (abs alcohol) for 1 hour. At room temperature
2) Intermedium on tissue rocker for (agitation): Xylin for (1 hour) then again Xylin for (1 hour). At room temperature
3) Pre-infiltration solution; Solution preparation: 100 ml of basis solution + ½ g Hardener 1.
- Solution used on tissue rocker for (agitation): 1 Hour At room temperature
4) Infiltration solution; Solution preparation: 100 ml of basis solution + 1.5g Hardener 1 + 10g of powder.
- Solution used for 24 Hour At 4C
5) Polymerization: Solution preparation:
- Stock A (100ml): 16g of powder + 80ml basis solution (mix until dissolve) + 0.8g Hardener 1 then top up the solution until 100 ml is reached.
- Stock B (100ml): 0.8 ml Hardener 2 + 0.4 ml Regulator + 100 ml basis solution
Finally, the polymerization solution is used in a ratio of 9 parts from stock A + 1 part of stock B mixed immediately before use.
We have tried a number of conditions to see if the polymerization will happen:
- Solution with the tissue at (RT, 4C and - 15C) for 24H
- Solution with the tissue at (RT, 4C and - 15C) for 72H
- Solution without the tissue at (RT, 4C and - 15C) for 24H
However, all of that ended unsuccessfully.
I would really appreciate any insight or help to this matter
Sincerely

Hi,
I have two samples containing 12-24% Ethanol (diluted by distilled water). I am wondering if these samples are frozen and then freeze dried, would that either decrease or get rid of the ethanol concentrations all together from sample?
Kind regards
I am a first year Ph.D. student in Cell and Molecular Biology department, UT. I am going to start a project on Breast Cancer and for this I need to be skilled on cell culture. I never did cell culture in my undergrad and now after shadowing my PI and seniors in the lab, I started my own session. But unfortunately my cells are getting contaminated. I wash my hands, rub my hand with alcohol, sterilize my hood with alcohol, spray alcohol in every bottle of reagents I use, Using auto pipet ( Big pipet). What else I am missing? I am feeling so pissed off because my seniors are doing the same but they are not facing the contamination. Please help me to overcome this situation.
For various reasons, I need to avoid DMSO with my cells. So I wonder if isopropyl alcohol (2-propanol) could be used instead of DMSO to create my stock solutions library?
I have learned that the polarity index of isopropyl alcohol is 3.9 (H20= 10.2; DMSO = 7.2). So, theoretically, it could be a better solvent for non-polar compounds than DMSO. Moreover, it is physiological (the normal concentration in human plasma is 80 uM, against 0 for DMSO). And, the cherry on the cake: it is sterilizing (no need for sterile filtration of the solution, so no loss of solution during filtration) and it will remain liquid at -20 (no freezing-thawing). Furthermore, once added to the saline solution, it will be salted out and then evaporate, so only traces will eventually be present in the culture medium.
Thus, the theoretical part of the problem seems to be very advantageous. But according to the literature, it is only rarely used. What is reason? I haven't seen any booby trap?
thank you
i am finding that drug court officers abiding by SAMSHA best practices protocol set up decades ago, have not been educated in interpreting results (they arent medical students) They look for the positive but dont know what other information on the lab report means.
i have reviewed two reports which i believe i could be great questions on a test . 1) the first one is positive for alcohol and pot, everything looks normal, the client swears they are clean. The interpreter missed the significance of the abnormal ph level of 10 in the urine, I understand that to be an indication that the sample has been contaminated. Am i right?
(no one can pee a 10, you are screaming at 7.5 to 8 because it is burning.
2) the second scenario involves a client who swears she is clean but got a positive for alcohol. the sample was taken dec 22 before christmas, was flown to San Diego, where it sat for 6 days until it was processed. the woman has candida for a decade. the candida feasted off of the sugars in the urine, metabolizing it to alcohol for 6 days.
she faces jail time for this misintepretation of the results. This is an expired specimen in my opinion regardless of refrigeration. Am i right?
What reaction(s) can be expected between Si and ethylene glycol when mechanical energy is added? T < 70°C, fractured Si surface of many orientations, not oxidized, not passified. Inert gas atmosphere. Little, but some, O2 (g) is present except for what is dissolved in the alcohol. It is not degassed.
I’m testing antioxidants using DPPH. The extract is dissolved in 60% ethanol. I would like to know if DPPH is dissolved with absolute ethanol, the percentage of alcohol have an effect?
Can I use the extract dissolved in 60% ethanol or should the extract be precipitated before testing?
Thank you
The purchased EVA (VA content 40%) product is dissolved in toluene solution, and then a mixture of sodium hydroxide and alcohol is added, the concentration is about 1mol/l and 0.25mol/l. The infrared test results of the product are normal, but it has been unable to dissolve in DMSO. There is no major research in this area can answer or discuss. Whether the EVA synthesized by oneself and then make EVOH will dissolve in dmso better.
Alcohol ink what is the alcohol ink coposition? and what is the additive which help in adhestion/coherent property of alcohol ink ?
It always need to functionalize a secondary alcohol with leaving group (e.g. OTf, OMs), nucleophilic substitution of the leaving group to afford an OH with configuration inversions , and then functionalizing the OH again and substituted with NaN3 (or Mitsunobu reaction, e.g. DPPA) .
Another method is oxidation of the secondary alcohol and then reduction the ketone to afford OH with a pair of enantiomer, and then do same things again.
Is there any efficient method to directly turn a secondary alcohol into the azide and keep configuration retention?
Or any efficient method to directly Azidation and to avoid the elimination reaction?
“Practice what you preach,” is a common saying across the world. Akshay Kumar, however, learnt it the hard way. His endorsement of a pan masala brand despite his statement against the consumption of alcohol and pan Masala left him at the receiving end of his own fandom’s ire, who excoriated him. Even his apology was not good enough. Social media users want him to refrain from surrogate advertisement, a form of advertising which is used to promote regulated products, like cigarettes and alcohol, in the disguise of another product.
https://medium.com/@visheshsharma124/should-celebs-refrain-from-surrogate-advertisement-b54f4f86be32
Surrogate advertising is a form of advertising that is used to promote products which are banned or limited from advertising under government regulations, such as cigarettes and alcohol, via advertising another product produced by the same company in order to raise brand awareness.
Celebrities have a large following and their endorsements can have a significant influence on people's purchasing decisions. When celebrities endorse surrogate products, they are essentially promoting harmful products to their fans, including children and young adults.
Here are some of the reasons why celebrities should refrain from surrogate advertisement:
- Surrogate products are harmful. The products that are typically advertised through surrogate advertising are harmful to health, such as cigarettes, alcohol, and tobacco products. When celebrities endorse these products, they are encouraging their fans to use them, even though they know the risks.
- Surrogate advertising is misleading. Surrogate advertising is designed to mislead consumers into thinking that they are buying a different product, when in reality they are buying a harmful product. Celebrities who endorse surrogate products are complicit in this deception.
- Celebrities have a social responsibility. Celebrities have a large following and their actions can have a significant impact on society. When they endorse harmful products, they are sending a message that it is okay to use those products. This can lead to increased consumption of harmful products and negative health consequences.
Some people argue that celebrities should be free to endorse any product they want, but it is important to remember that surrogate products are harmful and that celebrities have a social responsibility. By refraining from surrogate advertisement, celebrities can help to protect their fans and promote public health.
In addition to the ethical concerns, there are also legal risks associated with surrogate advertising. In many countries, surrogate advertising is regulated or even banned. Celebrities who endorse surrogate products could face fines, legal action, and damage to their reputation.
Overall, there is no good reason for celebrities to endorse surrogate products. It is harmful, misleading, and could have legal consequences. Celebrities should use their influence to promote positive messages and encourage their fans to make healthy choices.

We are part of a charitable foundation working hard to raise awareness about the link between concurrent alcohol and cocaine use and the subsequent psychoactive substance created in the body known as Cocaethylene which is thought to increase the risk of suicide in the early morning comedown. We feel the male suicide figures in the UK and in many other countries will be contributed to by the prolonged block of dopamine reuptake, catastrophic thoughts, violent actions and impulsivity which has led to suicide by harm in a number of known cases. Toxicological analysis of suicide decedents has contributed to the knowledge base. My son left this world in this exact way as have many others and we want to find ways to prevent harm or death for other young people and conducting this research is part of that fight. If you have any ideas suggestions or can point me in the direction of any papers of interest, it will be much appreciated.
I'm sure it is associated with Picro-Sirius red as it doesnt occur until I apply this. I originally thought it may be a drying artefact however I have tried not drying the slides and it still occurs. I have also tried leaving the slides longer in alcohol but this didnt help, and if I leave them too long all of the yellow staining is removed from the tissue sections. Even if I do not apply weigerts haematoxylin the artefact can still be seen within some cell nuclei. The actual connective tissue components of the tissue section look fantastic but this can be seen in other areas. It seems to be worse on columnar epithelial cells and liver hepatocytes.
Method is as follows:
0.5%acidified potassium permanganate - 5 mins
1%oxalic acid -1 min
Rinse in alcohol put into Millers solution in 37 degree Celsius oven - 2 hrs
Rinse in alcohol then distilled water
Weigerts hx - 15 mins
0.5% acid alcohol - 3to 5 seconds
Blue in tap water - 3 to 5 mins
Picro-Sirius red - 1 hrs ( I have tried different timings for this stage from 20 mins to 1 hrs and the same problem is encountered. Solution is ready to use not made in house)
Blot dry
DCM ( rapidly through alcohols)




Much better if purification methods will not involve column chromatography.I've seen Mitsonubu's reaction and use of Diisopropyl azodicarboxylate and triphenylphosphine as a catalyst in the reaction. Can somebody suggest a clear method on how to do this.Thank you.

Hi, recently i did an analysis on 2 hair samples to try and detect alcohol (or ethylglucuronide). This is the protocol i followed. I used HPLC and did not get any results. The machine was capable to detect another persons alcohol in hair analysis but not mine. This person used another protocol to extract the ethylglucuronide so I think I went wrong with the method but I don't know where the error lies.

Hello, I am trying to remove genomic DNA from RNA samples, I check my RNA before treating with DNase turbo and my bands look intact and of good quality, 260/270 ratio in 2.2 and 260/230 ratio 3n 2.1, I use 8mg of RNA with 1 ug of DNAse and 2.5 of 10x Buffer in a final volume of 25 uL, I digest at 37 °C for 60 min and then bring my solution to 300 uL, add 50 uL of phenol and 250 Chloroform isoamyl alcohol (24 :1), I add isoamyl alcohol and lithium acetate and let it precipitate overnight, the next day I do my washings with 75% RNA grade absolute alcohol and let my pellet dry and resuspend in 20 uL in DEPC water, when I see again my MOPS agarose gel and 37% chloroform my bands look very faint or I can't see them, any tips to avoid losing the sample?
Could someone help me with a suitable process with doping graphene? As I read from many papers, graphene needs to be ultrasonicated to eliminate the solvent (alcohol) before being doped into the polymers gel.
However, if I directly buy the powder graphene, can I directly pour it into the polymers?
Thank you.
I'm trying to separate isoamyl alcohol and optically active amyl alcohol from fusel oil. I have done a rigorous distillation to get maximum concentration in bottoms of block B3. Since the boiling point difference is very less , simple distillation won't work here (3-methyl -1-butanol is 131 deg_C and boiling point of 2-methyl-1-butanol is 128 deg_C) .
I thought of using crystallization process to separate them but it's not economically feasible process.
I have attached the simulation sheet and the results developed by Aspen.

Alcohol is a central nervous system depressant
Hello, there are some holes/porous structure on my nissl staining results as shown in the picture below. Does it look like freezing defects or slides over dried? Some advice will be appreciate. The procedure is described below :
The mouse was perfused fixed with pbs and 4% pfa and then head was left in 30% surcose pfa solution (w/v) for very long time( I know this looks weird but previous lab member could get decent Nissl staining results from it). Then the mouse head was frozen in -80 and brain was extracted with ephys probe embedded inside. Afterwards brain was embedded in oct and put in -80 for freezing and preserving. Frozen oct block is frozen sectioned, dried for 12hrs at RT and nissl stained(5min xylene defat, descending alcohol 3min rehydrate, di water 1min, toludine blue 4 min, ascending alcohol for differenti and xylene 30min for clearing.
Thanks

I isolated RNA from the exosome using Total RNA Isolation Kit and stored it directly at -20 C. today I conversted it into cDNA and then ran the qPCR but I didn't get the amplification. I personally think that my RNA may have been degraded as it was stored at -20 C and I added mothing with it. However, various studies and Kits have said that RNA once isolated should firstly be kept in NUCLEASE FREE WATER or ALCOHOL. so kindly tell me as to how to store the RNA properly. and Nuclease free water will be good or the ALCOHOL??? Also, tell me the concentrations as well please.
For lithium carbonate preparation it‘s been saying that %70 alcohol saturated with lithium carbonate. But ı can’t dissolve it in distilled water or alcohol.
I'm researching the antimicrobial effect of laurel extracts, which are made with different alcohol percentages (5%,60%, and 96%). I want to let the alcohol evaporate and replace it with something else so that the alcohol can't have any effect on the bacteria. When the alcohol has evaporated, non-polar compounds also remain, these cannot dissolve in, for example, water.
Does anyone have a solution for this?

I am doing an acetylation reaction of a series of heavy alcohols, with high boiling points, with acetic acid, the conversion in most cases are at most 94%, I need to remove the rest of alcohol reagent, what should I do?
Because the alcohol’s boiling points are above 200 C , distillation in vacuum reduces the ester as well, so the yield diminishes.
In an epidemiological study (eg: the effect of alcohol on Hypertension), if the value of the odds ratio is less than 1 (eg:0.45) but it is statistically significant.

I have measured Quercetin amount using spectrophotometer at 380nm.1mg/1ml ( Que: Absolute Alcohol). I done 5 serial dilution, ı found conc. 0,98. I am sharing with you the excel. Do you think is it correct?
I am currently trying to measure a number of ichthyological specimens preserved in wet collections. I am generally using calipers but have found that my calipers are too short to collect standard length or head length in some very long-snouted species (i.e., gars), as well as unable to measure body girth.
To take these measurements I have been using a cheap 60 cm tape measurer, but what I have found is that when I tried measuring these specimens the alcohol was rapidly absorbed by the measuring tape and the entire tape measurer started falling apart. Something in the tape measurer was reacting to some chemical in the preservatives of the fishes and causing the adhesive to dissolve.
I know that other ichthyologists, as well as herpetologists, mammalogists, etc., often use tape measurers to take very long measurements on formalin-fixed specimens in alcohol. I was wondering if there was any specific brand of tape measurer that other scientists have found does not fall apart when exposed to alcohol?

- Alcohol has effects, both short-term and long-term, on almost every single organ of your body.
- Overall, the evidence suggests that there is no “safe limit” – in fact, the risk of damage to your health increases with each drink of alcohol consumed.
- Alcohol use, especially heavy use, weakens the immune system and thus reduces the ability to cope with infectious diseases.
- Alcohol, even in very small quantities, is known to cause certain types of cancer.
- Alcohol alters your thoughts, judgment, decision-making, and behavior.
- Alcohol, even in small amounts, is a risk to the unborn child at any time during pregnancy.
- Alcohol increases the risk, frequency, and severity of perpetration of interpersonal violence such as intimate partner violence, sexual violence, youth violence, elder abuse, and violence against children.
- Alcohol increases the risk of death and injury from road traffic injuries, drowning, and falls.
- Heavy use of alcohol increases the risk of acute respiratory distress syndrome (ARDS), one of the most severe complications of COVID-19.

Hello, I'm studying metal-catalyzed reactions between oleic acid + oleylamine (amidation) and oleic acid + oleyl alcohol (esterification). I have a general sense that, all conditions being equal, amidation should be faster, perhaps due to the basicity of the amine, but that seems sort of vague and I'm trying to get a full understanding of what I should expect. Any help would be much appreciated. Thanks!
I work with bat's helminths taxonomy. The ideal is to work on fresh hosts, but some bats species are highly threatened and it's not possible to obtain fresh carcasses or other alternatives. For these cases, I'm thinking about recovering the parasites from bats in biological collections. Howe
