And the article contained the following:

The role of calcium in fruit ripening has been established, however knowledge regarding the mol. anal. at fruit tissue-level is still lacking. To address this, we examined the impact of foliar-applied calcium (0.5% CaCl2) in the ripening metabolism in skin and flesh tissues of the sweet cherry ‘Tragana Edessis’ fruit at the harvest stage. Exogenously applied calcium increased endogenous calcium level in flesh tissue and reduced fruit respiration rate and cracking traits. Fruit metabolomic along with transcriptomic anal. unraveled common and tissue-specific metabolic pathways associated with calcium feeding. Treatment with calcium diminished several alcs. (arabitol, sorbitol), sugars (fructose, maltose), acids (glyceric acid, threonic acid) and increased ribose and proline in both fruit tissues. Moreover, numerous primary metabolites, such as proline and galacturonic acid, were differentially accumulated in calcium-exposed tissues. Calcium-affected genes that involved in ubiquitin/ubl conjugation and cell wall biogenesis/degradation were differentially expressed between skin and flesh samples. Notably, skin and flesh tissues shared common calcium-responsive genes and exhibited substantial similarity in their expression patterns. In both tissues, calcium activated gene expression, most strongly those involved in plant-pathogen interaction, plant hormone signaling and MAPK signaling pathway, thus affecting related metabolic processes. By contrast, calcium depressed the expression of genes related to TCA cycle, oxidative phosphorylation, and starch/sucrose metabolism in both tissues. This work established both calcium-driven common and specialized metabolic suites in skin and flesh cherry tissues, demonstrating the utility of this approach to characterize fundamental aspects of calcium in fruit physiol. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Name: 2,3-Dihydroxypropanoic acid

Marzec, Agata; Kowalska, Jolanta; Domian, Ewa; Galus, Sabina; Ciurzynska, Agnieszka; Kowalska, Hanna published an article in 2021, the title of the article was Characteristics of Dough Rheology and the Structural, Mechanical, and Sensory Properties of Sponge Cakes with Sweeteners.Computed Properties of 585-88-6 And the article contains the following content:

Changes in the rheol. properties of dough, as well as the microstructural, mech., and sensory properties of sponge cakes, as a function of the substitution of sucrose in a formulation with maltitol, erythritol, and trehalose are described. Moreover, the relationship between the examined properties was investigated. The replacement of sucrose with maltitol or trehalose did not affect the consistency index, whereas erythritol caused a decrease in its value. X-ray tomog. was used to obtain the 2D and 3D microstructures of sponge cakes. All studied sweeteners caused the sponge cakes to have a typical porous structure. Erythritol and maltitol resulted in about 50% of the pores being smaller than 0.019 mm2 and 50% of the pores being larger than 0.032 mm2. Trehalose resulted in a homogeneous microstructure, 98% of whose pores were similar in size (0.019 to 0.032 mm2). The sponge cakes with polyols had a higher structure index than did the trehalose and sucrose samples. There were also significant differences in color parameters (lightness and chromaticity). The crust of the sponge cake with sweeteners was lighter and had a less saturated color than the crust of the sponge cake with sucrose. The sponge cake with maltitol was the most similar to the sponge cake with sucrose, mainly due to the mech. and sensory properties. Trehalose led to the samples having high adhesiveness, which may limit its application as a sucrose substitute in sponge cake. Sensory properties were strongly correlated to cohesiveness, adhesiveness, and springiness and did not correlate to the 2D and 3D microstructures. It was found that 100% replacement of sucrose allows for a porous structure to be obtained. These results confirm that it is not the structure, but most of all the flavor, that determines the sensory perception of the sponge cakes. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Computed Properties of 585-88-6

On November 30, 2008, Henriks-Eckerman, Maj-Len; Suuronen, Katri; Jolanki, Riitta published an article.Synthetic Route of 4719-04-4 The title of the article was Analysis of allergens in metalworking fluids. And the article contained the following:

Background: Metalworking fluids (MWFs) are well-known causes of occupational contact dermatitis in machinists. Objective: To gain information about skin sensitizers in MWFs and to compare it with the information in safety data sheets (SDSs). Methods: A total of 17 samples of MWF concentrates were analyzed for skin sensitizers known or suspected to be used in MWF. Alkanolamines, formaldehyde, isothiazolinones, methyldibromo glutaronitrile (MDBGN), and iodopropynyl butylcarbamate (IPBC) were separated by liquid chromatog. Resin acids of colophonium (colophony) were separated by gas chromatog. The substances were identified with mass spectrometric detection and UV detection. Results: Of the MWFs, 15 contained 6-39% of alkanolamines, mostly monoethanolamine and triethanolamine. Formaldehyde was detected in all MWFs: the concentrations of total formaldehyde ranged between 0.002% and 1.3%. Benzisothiazolinone and octylisothiazolinone were detected in one fluid each. IPBC was detected in nine MWFs, and the highest concentration was 0.09%. Methylisothiazolinone and MDBGN were not detected in any of the fluids. Resin acids of colophonium were detected in seven MWFs in concentrations ranging from 0.41% to 3.8%. On the whole, the allergens analyzed were poorly declared in the SDSs. Conclusions: The content of total formaldehyde was not declared in any SDS. IPBC, a relatively new allergen, seems to be common in MWFs. Isothiazolinones may be relevant allergens of machinists, and they should be analyzed in MWFs in case other sources are not identified. The occupational relevance of pos. patch test results to MWF ingredients in machinists is difficult to determine if information in the SDSs is relied upon. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Synthetic Route of 4719-04-4

On November 30, 2011, Latorre, Nuria; Borrego, Leopoldo; Fernandez-Redondo, Virginia; Garcia-Bravo, Begona; Gimenez-Arnau, Ana Maria; Sanchez, Javier; Silvestre, Juan Francisco published an article.COA of Formula: C9H21N3O3 The title of the article was Patch testing with formaldehyde and formaldehyde-releasers: multicentre study in Spain (2005-2009). And the article contained the following:

Background. Formaldehyde and formaldehyde-releasers are common causes of allergic contact dermatitis. Objectives. To determine the frequency of sensitization to formaldehyde and seven formaldehyde-releasers. To establish and characterize groups of patients according to the results of patch testing. Materials and methods. We performed a 5-yr retrospective study, in six Spanish hospitals, of patients with pos. patch test reactions to formaldehyde or any of seven formaldehyde-releasers. Results. The most frequent allergens were formaldehyde (1.72%), imidazolidinyl urea (1.05%), quaternium-15 (0.88%), and diazolidinyl urea (0.79%). Patients with sensitization to only formaldehyde had a higher frequency of occupational dermatitis (25%) than patients with sensitization to only formaldehyde-releasers (9.5%). The most common sites of dermatitis were the hands (31.7%) in patients with sensitization to only formaldehyde and the face and legs (31.3% and 24.6%) in patients with sensitization to only formaldehyde-releasers. We found a subgroup of 25 patients who were sensitized to both imidazolidinyl urea and diazolidinyl urea, and only 6 of these (24%) were also sensitized to formaldehyde. Conclusions. The inclusion of imidazolidinyl urea and diazolidinyl urea in the baseline series of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) should enable better classification of patients allergic to formaldehyde, and could aid in their management.

On September 30, 2002, Trattner, A.; Farchi, Y.; David, M. published an article.Related Products of 4719-04-4 The title of the article was Cosmetics patch test: first report from Israel. And the article contained the following:

A total of 244 Israeli patients with suspected cosmetic contact dermatitis was patch tested on the upper back with the European standard series and a cosmetic series using Finn Chambers on Scanpor tape. The patches were removed after 2 days, and readings made on day 2 and day 3. A pos. response to one or more allergens in the cosmetics series was found in 80 patients. The most frequent allergens were methylchloroisothiazolinone + methylisothiazolinone, thimerosal, triethanolamine, and octyl gallate. Thus, its is recommended that a cosmetics series be added to the standard series in all patients with suspected cosmetic contact dermatitis.

On November 30, 1995, Hermansky, Steven J.; Neptun, Douglas A.; Weaver, Elizabeth V.; Ballantyne, Bryan published an article.Related Products of 2160-93-2 The title of the article was Clinical pathology changes related to cutaneous irritation in the Fischer 344 rat and New Zealand White rabbit. And the article contained the following:

An evaluation of 27 repeated dose cutaneous application studies (9 applications of 6 h over an 11-day period) indicated that several hematol. and clin. chem. parameters may be altered by chem. induced skin irritation. Irresp. of species, values that were generally decreased included Hb concentration, hematocrit, erythrocyte count, and serum concentrations of calcium, potassium, inorganic phosphorus, and creatinine. Values that were increased included the neutrophil and total leukocyte counts. Some species differences were seen; for example, while the platelet count and serum globulin concentration were increased in rabbits only, the serum glucose, sodium, and chloride concentrations were increased in rats only. The mean corpuscular volume (MCV), mean corpuscular Hb (MCH), and serum albumin and total protein concentrations were variably affected. Changes were generally well associated with the degree of cutaneous irritation, but did not appear to be related to the chem. class of the test substances, decreased food consumption, loss of body weight, or systemic toxicity of the chem.

On December 31, 1996, Ballantyne, Bryan; Leung, Hon-Wing published an article.Related Products of 2160-93-2 The title of the article was Acute toxicity and primary irritancy of alkylalkanolamines. And the article contained the following:

The acute handling hazards of several alkylalkanolamines were determined by investigating their potential acute toxicity and primary irritancy. Materials studied were N-methylethanolamine (MEA), N, N-dimethylethanolamine (DMEA), N, N-dimethylisopropanolamine (DMIPA), N-methyldiethanolamine (MDEA), and tert-butyldiethanolamine (BDEA). All these alkylalkanolamines were of comparable acute peroral toxicity in the rat (LD50 range 1.48-2.83 mL/kg). By 24 h occluded epicutaneous contact in the rabbit, MEA, DMEA and DMIPA were of moderate acute percutaneous toxicity (LD50 range 1.13-2.0 mL/kg), MDEA was of slight acute percutaneous toxicity (LD50 male 9.85 mL/kg, female 10.90 mL/kg), and BDEA of intermediate toxicity (LD50 6.4 mL/kg). Due to differences in vapor pressure the acute vapor exposure toxicity of the alkylalkanolamines to rats varied; MEA, MDEA and BDEA were of a low order of acute toxicity, and DMIPA was moderately toxic with an LT50 of 3.2 h for a saturated vapor atm. exposure. A 4 h-LC50 (rat combined sex) of 1461 ppm was determined for DMEA. All alkylalkanolamines studied, except MDEA, were moderately to markedly irritating and caused variable degrees of skin corrosivity; MDEA caused only transient minor skin irritation. In accord with the skin irritancy results, the eye irritancy from 0.005 mL MEA, DMEA, DMIPA and BDEA was severe, and that from MDEA was slight. Exposure to these compounds has implications for occupational health procedures. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Related Products of 2160-93-2

Zhang, Bin; Yao, Hui; Qi, He; Ying, Xiao-guo published an article in 2020, the title of the article was Cryoprotective characteristics of different sugar alcohols on peeled Pacific white shrimp (Litopenaeus vannamei) during frozen storage and their possible mechanisms of action.COA of Formula: C12H24O11 And the article contains the following content:

Sugar alcs., also known as polyols, have been widely applied in food products for their unique properties. In this work, the effect of soaking treatments composed of the sugar alcs. xylitol, sorbitol, erythritol, lactitol, mannitol, maltitol, and isomaltitol on the quality properties of peeled Pacific white shrimp during frozen storage were evaluated. Samples treated with water and sodium pyrophosphate (Na4P2O7) were designated as the neg. and pos. controls, resp. The results indicated that significant improvements were found in thawing, pressing, and cooking loss, myofibrillar protein content, myofibrillar Ca2+-ATPase activity, and textural variables in xylitol- and mannitol-treated shrimp as compared to that of control samples. Water mobility analyses showed that xylitol and mannitol effectively increased the relaxation times T21 and T22 and the percentage of A21 (trapped water) but decreased the percentage of A22 (free water) in muscle tissue. Addnl., the microstructural results indicated that soaking in xylitol and mannitol significantly slowed the damage caused to muscle tissues by large ice crystals. Here, the incorporated xylitol and mannitol mols. presumably replaced water mols. by forming large hydrogen bonds with the muscle proteins, thereby stabilizing their structures in the absence of water while in the frozen state and suppressing the destruction of tissue structure. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).COA of Formula: C12H24O11

On November 30, 2008, Aalto-Korte, Kristiina; Kuuliala, O.; Suuronen, K.; Alanko, K. published an article.Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Occupational contact allergy to formaldehyde and formaldehyde releasers. And the article contained the following:

Formaldehyde allergy is common and usually derives from formaldehyde-releasing biocides in cosmetic and other products. To analyze patterns of patch test reactions to formaldehyde and formaldehyde-releasing compounds and the sources of sensitization. At the Finnish Institute of Occupational Health, we screened the patch test files for allergic reactions to formaldehyde and 12 formaldehyde-releasing compounds All patients with contact allergy to any of the substances were included, and their records were reviewed. Between Jan. 2001 and May 2007, we had patch tested 81 patients with formaldehyde allergy and 18 with independent allergy to some formaldehyde releaser. Of the formaldehyde allergies, 60 were new sensitizations, 25 of which were considered to be occupational. The most common source of occupational sensitization was metalworking fluids followed by creams and related products. Exposure to formaldehyde-releasing preservatives in liquid soaps and other rinse-off products was common in both occupational and non-occupational cases. Reactions to formaldehyde-releasing compounds were seen in 79% of the formaldehyde-allergic patients. Occupational formaldehyde allergy was common and occurred in metalworkers, hair-dressers, masseurs, and workers using protective creams, detergents, and liquid soaps. When compared with studies on general dermatol. patients, contact allergy to formaldehyde releasers without formaldehyde allergy was rare. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol
