The Total Syntheses of JBIR-94 and Two Synthetic Analogs and Their Cytotoxicities Against A549 (CCL-185) Human Small Lung Cancer Cells

We here disclose the total syntheses of the natural polyphenol JBIR-94 and two nonnatural analogs, whose structures are of interest for their bioactivity potential as radical scavengers. Although we initially attempted this by dually acylating both of putrecine’s amine nitrogens in a single pot, our endeavors with this method (which has been successfully reported by other groups) proved ineffectual. We accordingly opted for the lengthier approach of acylating each amine individually, which gratuitously prevailed and also aligns with separate literature precedent. Moreover, we here share our analysis of these target compounds’ cytotoxicities and IC50 values against A549 (CCL-185) human small lung cancer cells

The psychological impact of prosthodontic treatment—a discrete response modelling approach

Investigating the psychological impact of dental treatment is of high relevance to clinical decision makers and a promising approach for furthering patient satisfaction. This paper aims at detecting factors which influence the psychological impact of prosthodontic treatment and its relevance for the dentist. We apply microeconometric techniques and, specifically, control for sample selection bias in order to derive evidence from a panel database which measures oral health-related quality of life (OHIP-G) before and after treatment. The survey rests upon an initial evaluation of 381 patients between 2004 and 2005 and a follow-up in January 2006 (response rate 47%, corresponding to 180 patients) at the University Medical Centre Regensburg, Germany. Our findings indicate that persons of different age have unlike mindsets towards prosthodontic interventions and that there are gender differences with respect to the psychological sensitivity towards prosthodontic interventions. Moreover, the psychological impact attributable to treatment is influenced by the type of limitation in oral well-being before treatment. We could identify distinct factors including age, gender and the type of limitation in oral well-being as causing differentiation in the psychological impact of prosthodontic treatment. Specific patient characteristics may modulate the psychological impact of prosthodontic treatment

Intermittent explosive disorder amongst women in conflict affected Timor-Leste: associations with human rights trauma, ongoing violence, poverty, and injustice

Women in conflict-affected countries are at risk of mental disorders such as posttraumatic stress disorder and depression. No studies have investigated the association between experiences of abuse and injustice and explosive anger amongst women in these settings, and the impact of anger on women's health, family relationships and ability to participate in development.\ud \ud A mixed methods study including an epidemiological survey (n = 1513, 92.6% response) and qualitative interviews (n = 77) was conducted in Timor-Leste. The indices measured included Intermittent Explosive Disorder, posttraumatic stress disorder; severe distress; days out of role (the number of days that the person was unable to undertake normal activities); gender-specific trauma; conflict/violence; poverty; and preoccupations with injustice.\ud \ud Women with Intermittent Explosive Disorder (n = 184, 12.2%) were more disabled than those without the disorder (for >5 days out of role, 40.8% versus 31.5%, X²₍₂₎ = 12.93 p = 0.0016). Multivariable associations with Intermittent Explosive Disorder, controlling for the presence of PTSD, psychological distress and other predictors in the model, included the sense of being sick (OR 1.73; 95% CI 1.08–2.77); victimization as a result of helping the resistance movement (OR 2.33, 95% CI 1.48–3.68); war-related trauma specific to being a woman (OR 1.95, 95%, CI 1.09–3.50); ongoing family violence and community conflict (OR 1.88, 95% CI 1.27–2.77); extreme poverty (OR 1.23, 95%, CI 1.08–1.39); and distressing preoccupations with injustice (relating to 2/3 historical periods, OR 2.10, 95% CI 1.35–3.28). In the qualitative study, women elaborated on the determinants of anger and its impact on their health, family and community functioning, child-rearing, and capacity to engage in development. Women reflected on the strategies that might help them overcome their anger.\ud \ud Intermittent Explosive Disorder is prevalent and disabling amongst women in conflict-affected Timor-Leste, impacting on their health, child-rearing and ability to participate fully in socio-economic development
