“…The mechanisms of the infection are complex and not fully understood. It is only in rare cases that infected individuals develop invasive cancer, therefore, it was stated that pathogenic infections are necessary but not sufficient for cancer initiation or progression [1,5,11,19,28]. It was documented that in chronic inflammation, epithelial and inflammatory cells generate ROS and reactive nitric species (RNS), and release growth factors and cytokines, which may cause DNA damage and alterations in critical pathways leading to cancer development or progression [36].…”

“…According to various reports, although all human cancers are non-communicable diseases, infections may contribute to about 13-20 % of global human cancer burden, and it is estimated that about 35 % of all infection-associated malignancies are attributable to human papilloma virus (HPV) and Epstein-Barr virus (EBV) [1][2][3][4]. EBV and HPV infections are associated with different cancers, including gastric, cervical, and breast carcinoma, as well as head and neck cancer (HNC) [5]. As some studies revealed, EBV and HPV coinfection plays an important role in the malignant transformation of epithelial cells [6,7].…”

Recent reports have pointed to the link between persistent inflammation, oxidative stress, and carcinogenesis; however most of the studies concerning the role of viruses in head and neck cancer (HNC) are focused mainly on one type of virus. Our present study aimed to study the relationship between Epstein–Barr virus/human papilloma virus (EBV/HPV) coinfection and glutathione peroxidase (GPx) and superoxide dismutase (SOD) level in oropharyngeal cancer. Fresh-frozen tumor tissue samples were collected from 128 patients with oropharyngeal cancer infected with EBV or HPV or with EBV/HPV coinfection. After DNA extraction, EBV and HPV DNA was detected using a polymerase chain reaction (PCR) assay. GPx and SOD activity was determined in homogenates of cancer tissue using diagnostic kits produced by Randox Laboratories. Both GPx and SOD activity was statistically lower in patients with EBV/HPV coinfection than in a single EBV or HPV infection. Analysis of GPx and SOD activity in relation to histological grading and tumor, node (TN) classification revealed that in poorly-differentiated tumors, the level of antioxidant enzymes was lower compared with well-differentiated lesions and in cases with greater tumor dimensions and lymph-node involvement, both GPx and SOD activity was decreased. Further studies are necessary to clarify the influence of interplay between EBV, HPV, and oxidative stress on malignant transformation of upper aerodigestive tract epithelial cells.

“…Therefore, the use of hair dyes in children or pregnant women is not recommended. 53 Cases of neonatal medulloblastoma and cardiac malformations were also associated with the use of maternal hair dyes. [54][55][56] A Brazilian study, in 2013, associated the development of early-age leukemia to exposure to hair dyes and hairstraightening cosmetics by the pregnant women.…”

Medical professionals that treat patients with alopecia usually lack knowledge about hair cosmetics. Trichologists focus on hair cycling and growth problems and not on the hair shaft integrity. This may lead to abandon of the use of the prescribed treatment, such as topical minoxidil or to inadequate traumatic grooming habits that may jeopardize hair follicle health. Shampoos, hair dyes, and hair-straightening products may alter hair fiber structure, remove lipids, and elude protein. Hair procedures such as hair dying and straightening have side effects and health concerns, especially for pregnant women or sensitive hair and scalp patients. Hair breakage, follicle traction, frizz, contact dermatitis, and mutagenicity are possible side effects of hair cosmetics misuse. The proper use of hair care products may help to increase patients' adherence to alopecia treatments and avoid health problems related to inadequate application of hair cosmetics and procedures.

Aflatoxin B 1 in a peanut oil matrix certified reference material (CRM, GBW10176) has been issued for accurate determination of aflatoxin B 1 in real samples. This matrix CRM was prepared from commercial peanut oils naturally contaminated by aflatoxin B 1 , with the aid of a liquid−liquid extraction process. Specially, the certified value of CRM was determined using two individual approaches, liquid chromatography−isotope dilution tandem mass spectrometry and standard addition liquid chromatography−fluorescence detection techniques. More importantly, assessments of homogeneity and short-and long-term stabilities confirmed that the GBW10176 CRM was sufficiently homogeneous between packages or within package, and it could be stable up to 7 days stored below 50 °C or 18 months at 4 °C. The metrological traceability of GBW10176 was ensured by the application of pure aflatoxin B 1 (GBW10172). Its uncertainty was evaluated with the contributions from the characterization, homogeneity, and stability. Resultantly, the certified value of the aflatoxin B 1 CRM (GBW10176) was 23.4 μg/kg with an uncertainty of 3.1 μg/kg (k = 2).
