While smoking is the primary cause of lung cancer, only 11-24% of smokers develop the malignancy over their lifetime. The primary addictive agent in tobacco smoke is nicotine and variation in nicotine metabolism may influence the smoking levels of an individual. Therefore, inter-individual variation in lung cancer risk among smokers may be due in part to differences in the activity of enzymes involved in nicotine metabolism. In most smokers, cytochrome P450 2A6 (CYP2A6)-catalyzed C-oxidation accounts for >75% of nicotine metabolism, and the activity of this enzyme has been shown to correlate with the amount of nicotine and carcinogens drawn from cigarettes...

What was the nature of the CPD activity, practice-related feedback and/or event and/or experience in your practice? The article discussed medicines optimisation, which was defined as a patient-centred approach to safe and effective medicines use to ensure patients achieve the best possible outcomes. It emphasised that involving patients in decisions about their care will assist in ensuring they get the most from their medicines.

Kesai Wang, John-Stephen A Taylor
Cyclobutane pyrimidine dimers (CPDs) are DNA photoproducts linked to skin cancer, whose mutagenicity depends in part on their frequency of formation and deamination. Nucleosomes modulate CPD formation, favoring outside facing sites and disfavoring inward facing sites. A similar pattern of CPD formation in protein-free DNA loops suggests that DNA bending causes the modulation in nucleosomes. To systematically study the cause and effect of nucleosome structure on CPD formation and deamination, we have developed a circular permutation synthesis strategy for positioning a target sequence at different superhelix locations (SHLs) across a nucleosome in which the DNA has been rotationally phased with respect to the histone octamer by TG motifs...

The aim of this study was to characterize virulence determinants and antibiotic resistance profiles in enterococci obtained from various clinical sources in the northwest of Iran. A total of 160 enterococcal clinical isolates from various wards of University Teaching Hospitals were collected and specified by biochemical test, from September 2014 to July 2015. Identification of enterococci was confirmed by multiplex PCR in the genus and species level. Antibiotic resistance properties and virulence determinants were examined by phenotypic and molecular methods...

We analysed 15 autosomal STRs in 200 unrelated individuals (102 males and 98 females) and 17 Y-STRs in 102 unrelated males living in Jharkhand, India, to establish parameters of forensic interest. The examined autosomal STRs revealed high combined power of exclusion (CPE) and combined power of discrimination (CPD) as equal to 0.9999 and greater than 0.99999, respectively. The combined probability of match (CPm) and combined paternity index (CPI) for all 15 autosomal STR loci were found to be 5.15 × 10(-18) and 6...

Introduction: Genetic variants associated with nicotine dependence have previously been identified, primarily in European-ancestry populations. No genome-wide association studies (GWAS) have been reported for smoking behaviors in Hispanics/Latinos in the U.S. and Latin America, who are of mixed ancestry with European, African, and American Indigenous components. Methods: We examined genetic associations with smoking behaviors in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) [N=12,741 with smoking data, 5,119 ever smokers], using ~2...

Responses of melanocytes (MC) to ultraviolet (UV) irradiation can be influenced by their neighbouring keratinocytes (KC). We investigated the role of Nrf2 in regulating paracrine effects of KC on UVB-induced MC responses through phosphorylation of MAPKs in association with oxidative stress in primary human MC cocultured with primary human KC using a transwell co-culture system and small-interfering RNA-mediated silencing of Nrf2 (siNrf2). The mechanisms by which Nrf2 modulated paracrine factors including α-melanocyte-stimulating hormone (α-MSH) and paracrine effects of KC on UVB-mediated apoptosis were also assessed...

BACKGROUND: Completion of continuing professional development (CPD) is mandatory for Medical Oncologists and Trainees (MO&T). Pharmaceutical companies may fund some CPD activities, but there is increasing debate about the potential for conflicts of interest (COI). AIM: We aimed to assess current practices around funding to attend CPD activities. METHODS: An electronic survey was distributed to Australian MO&T. The survey asked questions about current practices, institutional policies and perceptions about attending CPD funded by pharmaceutical companies...

Brassinosteroids (BRs) are plant steroidal hormones that play important roles in many stages of plant growth. Several plant species produce ecdysteroids, which are known as insect molting steroid hormones. In this study, we evaluated the biological activities of three hydroxysteroidal compounds, 20-hydroxyecdysone (ECD), 7,8-dihydro-8α-20-hydroxyecdysone (DHECD), and 7,8-dihydro-5a,8a-20-hydroxyecdysone (a-DHECD), and compared their activities with that of brassinolide (BL), the most potent BR. In rice, DHECD and a-DHECD enhanced the degree of lamina inclination, as do BRs...

PURPOSE: To investigate whether parental smoking around the time of pregnancy or maternal consumption of beverages (alcohol, coffee, or tea) during pregnancy were associated with the risk of CBT. METHODS: We pooled data from two French national population-based case-control studies with similar designs conducted in 2003-2004 and 2010-2011. The mothers of 510 CBT cases (directly recruited from the national childhood cancer register) and 3,102 controls aged under 15 years, frequency matched by age and gender, were interviewed through telephone, which included questions about prenatal parental smoking and maternal consumption of alcohol, coffee and tea...

Clinical progressive disease (cPD) occurs during neoadjuvant chemotherapy (NAC) in 3-5% of triple-negative breast cancer (TNBC) patients. We aimed to identify the histopathological and immunohistochemical parameters that are correlated with the TNBC that showed cPD. We identified 22 TNBCs that showed cPD during NAC (cPD group) and 80 TNBCs that did not receive NAC (control group). Using surgically resected tumor specimens, we performed histopathologic examinations and immunohistochemical analysis of 11 molecules that appeared relevant to epithelial-mesenchymal transition (EMT), and basal-like, molecular apocrine and other features...

Ultraviolet-B radiation (285-320 nm) elicits a number of cellular signaling elements. We investigated the preventive effect of linalool, a natural monoterpene, against UVB-induced oxidative imbalance, activation of mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling in HDFa cells. We observed that linalool treatment (30 μM) prevented acute UVB-irradiation (20 mJ/cm2) mediated loss of activities of antioxidant enzymes in HDFa cells. The comet assay results illustrate that linalool significantly prevents UVB-mediated 8-deoxy guanosine formation (oxidative DNA damage) rather than UVB-induced cyclobutane pyrimidine (CPD) formation...
