“…Persulfate salts are widely used in hair-bleach formulas because they are potent oxidants. In 1963, Calnan and Shuster [6] ®rst reported that a number of patients had been seen with generalized histamine reactions as well as urticarial and dermatitic reactions following the use of hair bleach. Since then, several reports of occupational asthma caused by persulfate salts in hairdressers have been published [1,4,9,10,18,19,22,25].…”

Occupational type exposure tests in two female hairdressers with occupational asthma gave, in one, an immediate asthmatic reaction to the mixing of a bleach containing potassium persulphate with hydrogen peroxide and also immediate skin test reactions to sodium and potassium persulphate, and in the other a non-immediate asthmatic reaction and negative skin tests to the persulphate preparations and also immediate skin and bronchial reactions to an extract of henna.

“…[2,3] Persulfates, a key ingredient in flour, are a source of sulfate (SO 2 4 ) free radicals under neutral pH. [4,5] Due to the higher oxidizing power of the sulfate radical (E 0 5 12.60 V) and longer half-life period over the OH radical, it has drawn attention in recent times as a powerful oxidizing agent. [6][7][8] Many chemical and cosmetic industries require persulfates as their key components [9] and workers often suffer from skin and respiratory diseases due to hypersensitive reactions.…”

“…[12] Cobalt is an integral component of vitamin B12 and thus physiologically found in most tissues mainly in liver and kidney. [13,14] Gill et al, reported the formation of oligomeric species (dimer, trimer, tetramer) when RNase A was exposed to KHSO 5 in presence of metal ions such as Ni 21 and Cu 21 and the high molecular weight species were identified using SDS-PAGE. [12] An important biomarker of oxidative stress is the dityrosine moiety generated due to the covalent linkage of two Tyr residues.…”

β‐cyclodextrin encapsulated polyphenols as effective antioxidants

Formation of dityrosine (DT) cross-linkages in proteins is one of the most widely used markers of oxidative stress. Ribonuclease A (RNase A) has 6 Tyr residues and shows a characteristic DT fluorescence peak upon oxidation in addition to major changes in its secondary structure. DT formation can be prevented by using polyphenols (GA, ECG, and EGCG) which are known to have strong antioxidant activity. However, it has been observed that ECG and EGCG initiate protein oligomerization due to protein-polyphenol cross-linkages. To prevent the formation of such crosslinkages we have used b-cyclodextrin (b-CD) to encapsulate the polyphenols and studied its antioxidant properties along with that of free polyphenols. The polyphenol/b-cyclodextrin (b-CD) inclusion complexes not only prevent DT formation but also reduce protein oligomerization. This may be attributed to the fact that the quinone forming rings of ECG and EGCG become encapsulated in the cavity of b-CD and are no longer available for protein cross-linking.b-cyclodextrin encapsulation, dityrosine, oxidative stress, polyphenols, protein oligomerization | I N TR ODU C TI ONBiological aging in mammalian cells is a direct indication of oxidative stress in proteins. [1] These oxidatively modified forms of proteins are generated due to the presence of reactive oxygen species (ROS) such as hydroxyl and superoxide free radicals. [2,3] Persulfates, a key ingredient in flour, are a source of sulfate (SO 2 4 ) free radicals under neutral pH. [4,5] Due to the higher oxidizing power of the sulfate radical (E 0 5 12.60 V) and longer half-life period over the OH radical, it has drawn attention in recent times as a powerful oxidizing agent. [6][7][8] Many chemical and cosmetic industries require persulfates as their key components [9] and workers often suffer from skin and respiratory diseases due to hypersensitive reactions. [10] Generally, the lower thermal energy at room temperature (25-508C) is not sufficient enough to activate persulfate, but generation of SO 2 4 radical is facilitated in presence of metal cations. Since proteins tend to lose their structure and function at high temperatures, [11] we have carried out the oxidation of ribonuclease A (RNase A) in presence of persulfate using cobalt (II) ion at 378C. [12] Cobalt is an integral component of vitamin B12 and thus physiologically found in most tissues mainly in liver and kidney. [13,14] Gill et al., reported the formation of oligomeric species (dimer, trimer, tetramer) when RNase A was exposed to KHSO 5 in presence of metal ions such as Ni 21 and Cu 21 and the high molecular weight species were identified using SDS-PAGE. [12] An important biomarker of oxidative stress is the dityrosine moiety generated due to the covalent linkage of two Tyr residues. [15] Dityrosine bond formation is an indication of aging, and disease related problems since it generally occurs during amyloid fibril formation, [16] Parkinson disease, [17] cerebrospinal fluid damage, [18] and also in the cataract of the eye lens.
