Evidence on the conformation of HeLa-cell 5.8S ribosomal ribonucleic acid from the reaction of specific cytidine residues with sodium bisulphite. (1/981)

The reaction of HeLa-cell 5.8S rRNA with NaHSO3 under conditions in which exposed cytidine residues are deaminated to uridine was studied. It was possible to estimate the reactivities of most of the 46 cytidine residues in the nucleotide sequence by comparing 'fingerprints' of the bisulphite-treated RNA with those of untreated RNA. The findings were consistent with the main features of the secondary-structure model for mammalian 5.85S rRNA proposed by Nazar, Sitz, & Busch [J. Biol. Chem (1975) 250, 8591--8597]. Five out of six regions that are depicted in the model as single-stranded loops contain cytidine residues that are reactive towards bisulphite at 25 degrees C (the other loop contains no cytidine). The cytidine residue nearest to the 3'-terminus is also reactive. Several cytidines residues that are internally located within proposed double-helical regions show little or no reactivity towards bisulphite, but the cytidine residues of several C.G pairs at the ends of helical regions show some reactivity, and one of the proposed loops appears to contain six nucleotides, rather than the minimum of four suggested by the primary structure. Two cytidine residues that are thought to be 'looped out' by small helix imperfections also show some reactivity.  (+info)

DNA demethylase is a processive enzyme. (2/981)

DNA methylation patterns are generated during development by a sequence of methylation and demethylation events. We have recently demonstrated that mammals bear a bona fide demethylase enzyme that removes methyl groups from methylated cytosines. A general genome wide demethylation occurs early in development and in differentiating cell lines. This manuscript tests the hypothesis that the demethylase enzyme is a processive enzyme. Using bisulfite mapping, this report demonstrates that demethylase is a processive enzyme and that the rate-limiting step in demethylation is the initiation of demethylation. Initiation of demethylation is determined by the properties of the sequence. Once initiated, demethylation progresses processively. We suggest that these data provide a molecular explanation for global hypomethylation.  (+info)

Sulfitobacter mediterraneus sp. nov., a new sulfite-oxidizing member of the alpha-Proteobacteria. (3/981)

Analysis of PCR products of 16S rDNA of 680 isolates from Mediterranean Sea mesocosm experiments with taxon-specific 16S rDNA oligonucleotides revealed that 262 isolates belonged to the alpha subclass of the class Proteobacteria. Partial 16S rDNA sequence analysis of selected isolates and oligonucleotide probing with a Sulfitobacter-specific 16S rDNA probe affiliated 33 strains to the genus Sulfitobacter. Analysis of the HaeIII digest pattern of 16S rDNA revealed the presence of two groups; while 30 strains showed a pattern identical with that obtained for Sulfitobacter pontiacus DSM 10014T, a second group of three strains had a unique pattern that was different from that of the type strain. Five isolates of group 1 and one isolates of group 2, strain CH-B427T, were selected for detailed taxonomic analysis. All six isolates closely resembled the type strain Sulfitobacter pontiacus DSM 10014T in physiological reactions. However, strain CH-B427T differed quantitatively in the composition of fatty acids from Sulfitobacter pontiacus DSM 10014T and showed only 98.2% 16S rDNA sequence similarity with strain DSM 10014T. DNA-DNA reassociation value obtained for strains DSM 10014T and CH-B427T revealed 46% similarity. Based on the results of DNA-DNA reassociation and discrete differences in the nucleotide composition of 16S rDNA, a new species of the genus Sulfitobacter is proposed, designated Sulfitobacter mediterraneus sp. nov., the type strain being strain CH-B427T (= DSM 12244T).  (+info)

The relationship between pH and concentrations of antioxidants and vasoconstrictors in local anesthetic solutions. (4/981)

pH affects the efficacy of local anesthetics by determining the percentage of the lipid-soluble base form of the anesthetic available for diffusion and penetration of the nerve sheath. The purpose of this study was to determine the relationship between pH and the concentrations of antioxidant and vasoconstrictor in dental local anesthetic solutions over real-time and after accelerated aging. Several batches of lidocaine and mepivacaine with vasoconstrictors were tested. Results showed that, immediately upon receipt from the manufacturers, three batches were below the USP pH limit (pH 3.3), and two batches contained less than the minimum limit of vasoconstrictors (90%). Real-time tests on batches that were within normal limits revealed that solutions were stable past 4 yr. Accelerated aging tests revealed a strong correlation between a decrease in pH and loss of antioxidants and vasoconstrictors. In conclusion, a quality batch of local anesthetic should remain efficacious long past the manufacturer's stated shelf life; a batch that is less than optimal, or one that is exposed to environmental stresses, will degrade rapidly, and efficacy may be affected by decreases in pH and loss of vasoconstrictor. pH may be an inexpensive, readily available screening test for efficacy of local anesthetics.  (+info)

CpG island methylator phenotype in colorectal cancer. (5/981)

Aberrant methylation of promoter region CpG islands is associated with transcriptional inactivation of tumor-suppressor genes in neoplasia. To understand global patterns of CpG island methylation in colorectal cancer, we have used a recently developed technique called methylated CpG island amplification to examine 30 newly cloned differentially methylated DNA sequences. Of these 30 clones, 19 (63%) were progressively methylated in an age-dependent manner in normal colon, 7 (23%) were methylated in a cancer-specific manner, and 4 (13%) were methylated only in cell lines. Thus, a majority of CpG islands methylated in colon cancer are also methylated in a subset of normal colonic cells during the process of aging. In contrast, methylation of the cancer-specific clones was found exclusively in a subset of colorectal cancers, which appear to display a CpG island methylator phenotype (CIMP). CIMP+ tumors also have a high incidence of p16 and THBS1 methylation, and they include the majority of sporadic colorectal cancers with microsatellite instability related to hMLH1 methylation. We thus define a pathway in colorectal cancer that appears to be responsible for the majority of sporadic tumors with mismatch repair deficiency.  (+info)

Confluence-induced alterations in CpG island methylation in cultured normal human fibroblasts. (6/981)

Growth constraint of bacterial and human cells has been shown to trigger genetic mutation. We questioned whether growth constraint might also trigger epigenetic mutation in the form of CpG island methylation. Logarithmically growing normal human fibro-blasts (NHF) displayed little (0-15%) CpG methylation in select regions of three CpG islands [estrogen receptor (ER), E-cadherin (ECAD) and O (6)-methylguanine-DNA methyltransferase (MGMT)] examined. NHF grown to and left at confluence for 2-21 days showed little (<10%) CpG methylation in the ER and ECAD CpG islands. These confluent, growth-arrested cells, however, displayed extensive ( approximately 50%) methylation of the MGMT CpG island. CpG methylation in the MGMT CpG island was not associated with cellular senescence. The methylation was, however, heritable, but not permanent, as the level of CpG methylation in the MGMT CpG island of cells 4 population doublings following replating after confluence were no different from those in confluent cultures, but returned to levels noted in logarithmically growing cells by 10 population doublings following replating. These results suggest that growth constraint can trigger transient epigenetic change even in normal non-senescent human cells.  (+info)

Mechanism, structure-activity studies, and potential applications of glutathione S-transferase-catalyzed cleavage of sulfonamides. (7/981)

The mechanism of sulfonamide cleavage of PNU-109112, a potent HIV-1 protease inhibitor, by glutathione-S-transferase (GST) was investigated in the presence of reduced GSH. GST-catalyzed sulfonamide cleavage takes place via the nucleophilic attack of GSH on the pyridine moiety of the substrate with formation of the GS-para-CN-pyridinyl conjugate, the corresponding amine, and sulfur dioxide. Structure activity studies with a variety of sulfonamides indicate that an electrophilic center alpha to the sulfonyl group is required for cleavage. Substituents that withdraw electron density from the carbon atom alpha- to the sulfonyl group facilitate nucleophilic attack by the GS(-) thiolate bound to GST. The rate of sulfonamide cleavage is markedly affected by the nature of the electrophilic group; replacement of para-CN by para-CF(3) on the pyridine ring of PNU-109112 confers stability against sulfonamide cleavage. On the other hand, stability of sulfonamides is less dependent on the nature of the amine moiety. These principles can be applied to the synthesis of sulfonamides, labile toward cellular GST, that may serve as prodrugs for release of bioactive amines. Tumors are particularly attractive targets for these sulfonamide prodrugs as GST expression is significantly up-regulated in many cancer cells. Another potential application could be in organic synthesis, where protection of amines as the corresponding activated sulfonamides can be reversed by GST/GSH under mild conditions.  (+info)

Reduction of adenosine-5'-phosphosulfate instead of 3'-phosphoadenosine-5'-phosphosulfate in cysteine biosynthesis by Rhizobium meliloti and other members of the family Rhizobiaceae. (8/981)

We have cloned and sequenced three genes from Rhizobium meliloti (Sinorhizobium meliloti) that are involved in sulfate activation for cysteine biosynthesis. Two of the genes display homology to the Escherichia coli cysDN genes, which code for an ATP sulfurylase (EC 2.7.7.4). The third gene has homology to the E. coli cysH gene, a 3'-phosphoadenosine-5'-phosphosulfate (PAPS) reductase (EC 1.8.99.4), but has greater homology to a set of genes found in Arabidopsis thaliana that encode an adenosine-5'-phosphosulfate (APS) reductase. In order to determine the specificity of the R. meliloti reductase, the R. meliloti cysH homolog was histidine tagged and purified, and its specificity was assayed in vitro. Like the A. thaliana reductases, the histidine-tagged R. meliloti cysH gene product appears to favor APS over PAPS as a substrate, with a Km for APS of 3 to 4 microM but a Km for PAPS of >100 microM. In order to determine whether this preference for APS is unique to R. meliloti among members of the family Rhizobiaceae or is more widespread, cell extracts from R. leguminosarum, Rhizobium sp. strain NGR234, Rhizobium fredii (Sinorhizobium fredii), and Agrobacterium tumefaciens were assayed for APS or PAPS reductase activity. Cell extracts from all four species also preferentially reduce APS over PAPS.  (+info)

So why do some wines have more sulfites than others? And why do we add sulfites? Well, the history of added sulfites in wine dates back to Ancient Egypt, Greek, and Roman times. Vintners would burn pieces of sulfur in the empty vessels before filling them with wine in order to keep the wine from turning into vinegar (a process that happens naturally due mostly to a specific bacteria named acetobacter that is found all over the world). Sulfites keep the wine from turning into vinegar by preventing the growth of bacteria (there are actually several other types of bacteria that can grow in wine and cause spoilage too) as well as preventing the growth of some yeasts as well; hence why sulfites are listed as a preservative. Sulfites also protect the wine from ageing too quickly when the wine is exposed to oxygen; hence why sulfites are listed as an antioxidant. Without sulfites in wine, it is highly likely for your wine to turn into vinegar and/or turn brown and become like cooking sherry in short ...

All wines contain at least some small amount of sulfites. They are a natural result of the same fermentation process that turns grape juice into alcohol. Even wines that have not had any sulfites added during the winemaking process contain some amount of sulfites. Sulfur dioxide (SO2) is used by winemakers to keep freshly pressed must from spoiling. It keeps down the activities of native yeast and bacteria and preserves the freshness of the wine. Modern technology has allowed the use of significantly less sulfur than was used in the past but some is necessary to make a stable wine. Regulations in the United States require that domestic and imported wines carry warning labels if they have sulfites in excess of 10 parts per million. Wines that have less than 10 parts per million are not required to carry the Contains Sulfites label but they still contain sulfites in some level. ...
LAWRENCE - Winemakers have added sulfites to preserve their products since the time of the Roman Empire. Sulfites, a class of compounds including sulfur dioxide and sulfite salts, act as antioxidants and antibacterial compounds. They can occur naturally in the winemaking process or can be added by producers to preserve freshness and boost flavor in a vintage.. But, according to the U.S. Department of Agriculture, People who have an intolerance to sulfites can experience symptoms including chest tightness, hives, stomach cramps, diarrhea and breathing problems. The underlying mechanisms for sulfite intolerance are not completely understood. For some individuals, though, the sensitivity to sulfites may be an allergic type of response. People with asthma appear to be at an increased risk of having asthma symptoms following exposure to sulfites.. Due to these concerns, since 1988 wines sold in the U.S. containing more than 10 parts per million (10 ppm) of sulfites have been required to include the ...
According to Dr. Herbert Kaufman, a member of the Medical Board of AWARE (American Wine Alliance for Research and Education) in San Francisco, in response to an inquiry presented to him by the Wine Enthusiast magazine (Volume 7, Number 3, April 1994): ..The substance or substances which causes nasal congestion from wine have not been all identified, but some things have been demonstrated not to be the cause. Those include both histamine and a substance called seatonin. Regarding sulfites: While it is possible that sulfites can cause nasal flushing, itching, nasal congestion and even wheezing, there are other foods such as shrimp, prepared potatoes, sauerkraut, dried fruit, various prepared dips, beer and other beverages which contain greater concentration of sulfites than wine. So other foods should be causing the same symptoms.. The exact mechanism of symptom production from sulfites is thought to be through release of breakdown products of sulfites themselves. One reason that sulfites are ...
In none of the studies conducted in preganat rats, mice, hamsters and rabbits with oral administration of sodium bisulfite, sodium metabisulfite, potassium metabisulfite or sodium thiosulfate by gavage during the phase of organogenesis clear evidence of discernible effects on nidation or on maternal or foetal survival were observed. The number of abnormalities seen in either soft or skeletal tissues of the test groups did not differ from the number occurring spontaneously in the sham-treated controls. Thus, the NOAELs for maternal and developmental toxicity can be expected above the highest dose levels investigated: - sodium metabisulfite in rabbits: , 123 mg/kg bw/d - potassium metabisulfite in rats: , 155 mg/kg bw/d - potassium metabisulfite in mice: , 125 mg/kg bw/d - sodium bisulfite in mice: , 150 mg/kg bw/d - sodium bisulfite in rats: , 110 mg/kg bw/d - sodium bisulfite in hamsters: , 120 mg/kg bw/d - sodium bisulfite in rabbits: , 100 mg/kg bw/d - sodium thiosulfate in mice: , 550 mg/kg ...

Whole-genome bisulfite sequencing (WGBS) is becoming an increasingly accessible technique, used widely for both fundamental and disease-oriented research. Library preparation methods benefit from a variety of available kits, polymerases and bisulfite conversion protocols. Although some steps in the procedure, such as PCR amplification, are known to introduce biases, a systematic evaluation of biases in WGBS strategies is missing. We perform a comparative analysis of several commonly used pre- and post-bisulfite WGBS library preparation protocols for their performance and quality of sequencing outputs. Our results show that bisulfite conversion per se is the main trigger of pronounced sequencing biases, and PCR amplification builds on these underlying artefacts. The majority of standard library preparation methods yield a significantly biased sequence output and overestimate global methylation. Importantly, both absolute and relative methylation levels at specific genomic regions vary substantially

Reduced representation bisulfite sequencing (RRBS) is an efficient and high-throughput technique used to analyze the genome-wide methylation profiles on a single nucleotide level. This technique combines restriction enzymes and bisulfite sequencing in order to enrich for the areas of the genome that have a high CpG content. Due to the high cost and depth of sequencing needed to analyze methylation status in the entire genome, Meissner et al. developed this technique in 2005 in order to reduce the amount of nucleotides needed to be sequenced to 1% of the genome. The fragments that comprise the reduced genome still include the majority of promoters, as well as regions such as repeated sequences that are difficult to profile using conventional bisulfite sequencing approaches. Enzyme digestion: First, genomic DNA is digested using a methylation-insensitive restriction enzyme. It is integral for the enzymes to not be influenced by the methylation status of the CpGs (sites within the genome where a ...
Potassium metabisulfite is a common wine or must additive, in which it forms sulfur dioxide gas (SO2). This both prevents most wild microorganisms from growing, and it acts as a potent antioxidant, protecting both the color and delicate flavors of wine. A high dose would be 3 grams of potassium metabisulfite per six-gallon bucket of must (yielding roughly 75 ppm of SO2) prior to fermentation; then 6 grams per six-gallon bucket (150 ppm of SO2) at bottling. Most commercial wineries do not add more than 30 ppm at bottling.[citation needed] Some countries impose regulations on how much SO2 wines are allowed to contain.[4] Winemaking equipment is sanitized by spraying with a 1% SO2 (2 tsp potassium metabisulfite per L) solution. ...

Bisulfite sequencing is widely employed to study the role of DNA methylation in disease; however, the data suffer from biases due to coverage depth variability. Imputation of methylation values at low-coverage sites may mitigate these biases while also identifying important genomic features associated with predictive power. Here we describe BoostMe, a method for imputing low-quality DNA methylation estimates within whole-genome bisulfite sequencing (WGBS) data. BoostMe uses a gradient boosting algorithm, XGBoost, and leverages information from multiple samples for prediction. We find that BoostMe outperforms existing algorithms in speed and accuracy when applied to WGBS of human tissues. Furthermore, we show that imputation improves concordance between WGBS and the MethylationEPIC array at low WGBS depth, suggesting improved WGBS accuracy after imputation. Our findings support the use of BoostMe as a preprocessing step for WGBS analysis.

I have made 2 batches of of plain hypo fixer for my toning process that has gotten milky/cloudy after fixing approximately 50 8x10 prints. I am using some old Zone VI hypo (anhydrous I assume since it is 673 grams for making a gallon). To that hypo, I add 120 grams of sodium sulfite. It is hot in the south and my fixing bath was 77 degrees, if that has anything to do with it. In my printing process, I use fixer 24 at 4 minutes, then wash and dry the prints for toning later. When I tone,

Since the time of the Roman Empire, winemakers have added sulfites to preserve their products. Sulfites, a class of compounds including sulfur dioxide and sulfite salts, act as antioxidants and antibacterial compounds. They can occur naturally in the winemaking process or can be added by producers to preserve freshness and boost flavor in a vintage.. However, the US Department of Agriculture stated, People who have an intolerance to sulfites can experience symptoms including chest tightness, hives, stomach cramps, diarrhea and breathing problems.. Now, the University of Kansas School of Engineering is working toward the design and marketing of a low-cost, easy-to-use device that would filter up to 99% of sulfites from wine when it is poured from the bottle.. Our idea is that youd have a device like an aerator, said Mark Shiflett, foundation distinguished professor of Chemical & Petroleum Engineering, who is leading the investigation. Youd stick it on the top of the bottle - and as you ...

In this study, we sought to determine whether the increases in peroxidase activity and electrolyte leakage induced in maize (Zea mays L.) leaves by sodium bisulfite were causally related to the sodium bisulfite-induced increases in sporulation of the pathogen Bipolaris maydis race T on infected maize leaves. Pretreatment of detached leaves of maize inbred W64 A with sodium bisulfite (500 ,ig/ml) for 24 h in the dark at 28°C increased peroxidase activity in the Tms cytoplasm (susceptible) isoline compared with the N cytoplasm (resistant) isoline. No such differences in peroxidase activity between the two isolines were observed when detached leaves were pretreated with double distilled water. The sodium bisulfite-induced increase in peroxidase activity persisted even when leaves pretreated with sodium bisulfite were inoculated with R maydis race T and subsequently incubated for 48 h in the dark at 28° C. Similarly, pretreatment with sodium bisulfite caused a greater increase in electrolyte ...
The USDA is just prohibiting the growth of the Organic Wine category by not allowing ANY sulfites to be added. It is strange that wines made with organic grapes are put in the same category as a commercial wine, and being forced to put sulfites added on their label. This has a negative connotation, especially for those who do not understand that sulfites are not the cause of many allergies, and organic wineries are not adding the same levels as a typical commercial winery. Instead, there should be a cap on how many sulfites Organic Wines are allowed to include under the USDA certification, then those organic wineries that choose not to add any suflites could have the added benefit of putting NO sulfites added on their label. Win-Win for everyone and the Organic Wine movement can thrive and gain some momentum. ...
I am trying to obtain as much information as I can in reference to organic wine and sulfites. I am a diabetic and I am also allergic to sulfites. I have not been able to get any sound information on the subject. I would like to know if organic wine has any of its own natural sulfites. It would be great to have an occasional glass of wine but I am afraid to attempt it until I can get a better definition about the sulfites. I am allergic to sulfur in medication which is how I found out that was my problem with having alcoholic drinks. I look forward to hearing from you. And thank you for your time. ...
Diagenodes Premium RRBS(Reduced representation bisulfite sequencing) kit obtained excellent results with almost 90% alignment rate, 4.1 million CpGs covered and bisulfite conversion rates around 99.5% for all samples
Sequencing-based approaches have led to new insights about DNA methylation. While many different techniques for genome-scale mapping of DNA methylation have been employed, throughput has been a key limitation for most. To further facilitate the mapping of DNA methylation, we describe a protocol for gel-free multiplexed reduced representation bisulfite sequencing (mRRBS) that reduces the workload dramatically and enables processing of 96 or more samples per week. mRRBS achieves similar CpG coverage to the original RRBS protocol, while the higher throughput and lower cost make it better suited for large-scale DNA methylation mapping studies, including cohorts of cancer samples. ...

by W. Blake Gray.. While organic wine in the U.S. is a minor category, its about to become big in Europe. The EU has ruled the exact opposite of the US: that organic wine can contain sulfites. The EU will restrict the amount of sulfites they may contain: 100 ppm total for red wine, 150 ppm for white or rosé, as opposed to the 10 ppm allowed (and only when naturally occurring) in U.S. organic wine. (Conventional wines in the US are allowed 350 ppm.). This is a huge difference. In covering this issue, I have spoken to several natural wine producers - leaders in the green wine field - who said they might take the steps to be certified organic wine producers if allowed to add 50 ppm of sulfites to protect their wines from bacteriological harm. Wine doesnt get greener than the Natural Process Alliance, but the NPA adds sulfites. That should tell you something.. Until this week, there has been no such thing as organic wine in the EU, only wine made from organically grown grapes, a ...
In a system for removing sulfur oxides from flue gas, the gas is contacted by a primary extraction solution containing sodium sulfite as the active compound and some sodium bisulfite in a scrubber, and the resultant extract containing more sodium bisulfite is mixed with an alkaline solution containing regenerated sodium sulfite in a mixer to produce the primary extraction solution. A portion of the latter is bled off to a regenerator wherein the quantity of sodium bisulfite made in the scrubber reacts with calcium hydroxide to form regenerated sodium sulfite and large diameter calcium sulfite precipitates that remain suspended in the parent solution. This mixture is drawn off the regenerator by overflow, without pumping, for gravity flow to the eye of a thickener, wherein an increased density slurry of the mixture is withdrawn from the thickener well and directed to a rotary filter to produce a calcium sulfite filter cake. The resultant filtrate and the solids free overflow from the thickener provide

Pretreatment of the first true leaves of oilseed rape plants (Brassica napus cv. Bristol) with menadione sodium bisulphite (MSB) locally and systemically induced resistance, as shown by reduced lesion size and number, to infection by the fungal pathogen Leptosphaeria maculans, the causal agent of stem canker. Using a known systemic activator of salicylic acid-dependent PR-1 induction, acibenzolar-S-methyl (BTH; S-methylbenzo[1,2,3]thiadiazole-7-carbothiate) as a comparison, real-time PCR expression analysis of genes encoding a pathogenesis-related protein 1 (PR-1) and an ascorbate peroxidase (APX) demonstrated a systemic enhancement of APX expression in MSB-pretreated plants, with no effect on PR-1 expression, suggesting augmented reactive oxygen species production in MSB-pretreated plants. The results demonstrate MSB to be an effective resistance activator in oilseed rape, and potentially useful for the control of stem canker ...

Sulfites are routinely added in the winemaking process as a preservative to prevent the growth of bacteria and unwanted yeast. Without sulfites, most wine will turn to vinegar. These sulfiting agents - sulfur dioxide, sodium potassium sulfite, bisulfite, and metabisulfite - can be added at different times and in varying amounts depending on the type of wine being made. In general, white wine has a higher sulfite content than red and sweeter wines have more sulfite than drier wines. All wine contains naturally occurring sulfites so finding a wine that is completely sulfite-free would be unlikely. However, some winemakers offer organic wines with no added sulfites. In the US, new regulations in place since 2012 require that all wines with sulfite levels greater than 10 mg/L (ppm) be labeled as containing sulfites. Similar guidelines have been adopted by the EU and Britain. ...
For the home winemaker there is no reason to worry about whether Sodium or Potassium is the preferred legal entity to use. Both are completely safe and the reason Potassium is preferred is that wine is considered to be a low sodium food. Avoiding the addition of any sodium salt keeps it that way. But the amount of sodium in the few ppm of sodium bisulfite youll add is probably always inconsequential. Sodium is cheaper and wont screw up the stability of the wine if you add it. Potassium is much more expensive and, if a lot is added, can (at least in theory) cause a stable wine to become cold unstable. After adding a potassium salt like metabisulfite youd have to re-chill the wine to get the extra potassium bitartrate to drop out and make the wine stable again. As a practical matter, youre not likely to add enough potassium metabisulfite to cause stability problems. Similarly, if you add sodium bisulfite, youre not likely to add enough sodium to make any difference to the low sodium status of ...
I have heard from countless people about their presumed allergy to red wine. Or allergy to sulfites. How they can drink white wine, but not red. I have learned a lot about this, including the concept that in all likelihood many people who think they are allergic to sulfites probably are not. FYI - dried fruit and salad bars contain a much higher level of sulfites than does red wine. And oh yeah, white wine has plenty of sulfites as well, both naturally occurring sulfites and added sulfites (usually).. As always, if you have specific questions feel free to be in touch. But without further ado, Id like to reprint an article written by Jennifer Rosen (for localwineevents.com) titled Red Alert: taming the red wine headache. A funny & informative read.

We report a method for specific capture of an arbitrary subset of genomic targets for single molecule bisulfite sequencing, and for digital quantitation of DNA methylation at a single nucleotide resolution. We used targeted bisulfite sequencing to characterize the changes of DNA methylation during the de-differentiation of human fibroblasts into hybrid stem cells, and into induced pluripotent stem cells. We compared the methylation level of approximately 66,000 CpG sites within 2020 CpG islands on chromosome 12, chromosome 20, and 34 selected regions. A total of 288 differentially methylated regions were identified between fibroblasts and pluripotent cells. Methylation cluster analysis revealed distinct methylation patterns between fibroblasts and pluripotent cells. Furthermore iPS cells are globally more methylated than human embryonic stem cells, which could be due to the reprogramming process. This targeted bisulfite sequencing method is particularly useful for efficient and large-scale analysis of

The DNA methylation status in cells is significantly different in different types of cells, and its dynamic regulation may be closely related to the structure of chromatin in the nucleus. There are already available technologies for sequencing DNA methylation (whole genome bisulfite sequencing, WGBS) and chromatin structure (Hi-C) in the genomics field. However, due to fragment length limitations, traditional whole-genome bisulfite sequencing cannot effectively detect multi-site coordinated DNA methylation.. A few months ago, researchers from the U.S. University of California published an article titled Joint profiling of DNA methylation and chromatinarchitecture in single cells in Nature Methods, reporting a newly developed technology called Methyl-HiC enables simultaneous DNA methylation and chromatin structure determination.. Methyl-HiCs technology uses common Hi-C procedures to obtain DNA fragments, and then adds a bisulfite conversion step before library construction, and then performs ...
Posted: 2009-07-22. Sodium Bisulfite. Certain toilet bowl cleaners are almost 50 percent sodium bisulfite, and most commercial wines also contain it. When dissolved in water-based liquids, sodium bisulfite releases sulfur gas that kills bacteria, yeasts, molds, and fungi. It also prevents oxidation, which protects wine from turning to vinegar.. This popular compound has a dubious past. It was banned from use on raw fruits and veggies by the FDA in the 80s following the deaths of 13 people who unknowingly consumed produce treated with toxic amounts of the preservative. Today, the FDA maintains that sulfites are generally safe. The Center for Science in the Public Interest however, warns asthmatics and others sensitive to sulfites to avoid it completely. It is now most commonly used in pet foods, potato chips and dried and pickled foods.. Benzoyl Peroxide. What do white bread and acne cream have in common?

Sulfites are present in all wines both as an additive and as a natural by-product of fermentation, and many countries require that their presence be indicated on the label. From health issues (see Debunking myths, Page F4) to sulfur as a winemaking tool at a time when theres a push within the industry for wines made with minimal intervention, sulfur dioxide is in the spotlight like never before. Sulfur dioxide has been used in the production of wine for centuries - primarily as a buffer to keep wine from reacting with too much oxygen, but also to inhibit microbial spoilage (from bacteria or rogue yeasts) that could lead to off flavors and aromas, and as a winemaking technique to partly control fermentation. [...] working with little to almost zero SO{-2} is one of the rallying points of the natural wine movement, a blanket term used to describe wines made according to a philosophy of minimal intervention in the vineyard and cellar. In recent years in both France and Italy, winemakers such as
This research is focused on simultaneous inhibition of carbon steel (1020) corrosion and oxidative monoethanolamine (MEA) degradation in a carbon dioxide (CO2) capture process from simulated post-combustion coal-fired flue gas, where components typically present in the flue gas partly contribute to such problems. Therefore, in this work, various additives were selected to study in the effects of flue gas composition on both carbon steel (1020) corrosion and oxidative MEA degradation. Sodium chloride (NaCl), ferrous chloride (FeCl2), and hydrochloric acid (HCl) were selected to represent different sources of chlorides in the flue gas. Sulphurous acid (H2SO3), sulphuric acid (H2SO4), and nitric acid (HNO3) were selected to represent the aqueous solutions of sulphur dioxide (SO2), sulphur trioxide (SO3), and nitrogen dioxide (NO2), respectively. In addition, sodium bisulfite (NaHSO3), sodium sulfite (Na2SO3), sodium sulphate (Na2SO4), and ferrous sulphate heptahydrate (FeSO4·7H2O) were ...

Recent developments in DNA methylation analysis technologies have made it crucial for researchers to understand which tool is optimal for their epigenetic research. These new methods pose exciting opportunities never before imagined, allowing for epigenetic variation to be connected to phenotypic consequences on a much grander scale and at single-base resolution. In a recent issue of an epigenetics newsletter, The Decoder, scientists at Epigentek discuss the latest progress made in profiling genome-wide and region-specific DNA methylation and offer suggestions on choosing the best method specifically for your experiment.. They begin by describing a method called oxidative bisulfite-sequencing (oxBS-Seq), which now enables researchers to distinguish 5-hydroxymethylcytosine (5-hmc) from 5-methylcytosine (5-mc). It takes advantage of the chemical oxidation (KRuO4) of 5-hmc into 5-fC and ensures only 5-mc is detected by converting 5-fC to uracil by bisulfite treatment. Traditional bisulfite ...
The complex relationship between DNA methylation, chromatin modification, and underlying DNA sequence is often difficult to unravel with existing technologies. Here, we describe a novel technique based on high-throughput sequencing of bisulfite-treated chromatin immunoprecipitated DNA (BisChIP-seq), which can directly interrogate genetic and epigenetic processes that occur in normal and diseased cells. Unlike most previous reports based on correlative techniques, we found using direct bisulfite sequencing of Polycomb H3K27me3-enriched DNA from normal and prostate cancer cells that DNA methylation and H3K27me3-marked histones are not always mutually exclusive, but can co-occur in a genomic region-dependent manner. Notably, in cancer, the co-dependency of marks is largely redistributed with an increase of the dual repressive marks at CpG islands and transcription start sites of silent genes. In contrast, there is a loss of DNA methylation in intergenic H3K27me3-marked regions. Allele-specific methylation
Sulfites are a big subject of discussion in the wine world. While theyre essential to winemaking and give wine its shelf life, theyre demonized for wine related headaches to rashes, shortness of breath and a range of other ailments. Its commonly thought that sulfites are the primary cause of headaches when drinking wine. This may be true for a tiny percentage of people but its been largely disproven. Tannins, Alcohol, Latent Histamine and even the placebo effect are all more likely culprits. The truth is that the jury is still out on the total health effects of sulfites. Theyre used in.... ...
