Online persuasion: An examination of gender differences in computer-mediated interpersonal influence.

The purpose of this research was to investigate how computer-mediated communication affects persuasion in dyadic interactions. Two studies compared participants' attitudes after hearing a series of arguments from a same-gender communicator via either e-mail or face-to-face interaction. In Study 1, women showed less message agreement in response to e-mail versus face-to-face messages, whereas men showed no difference between communication modes. Study 2 replicated this finding and examined the impact of prior interaction with the communicator. For women, the condition that provided the least social interaction led to the least message agreement. For men, the condition that provided the most social challenge led to the least message agreement. Results are interpreted in terms of gender differences in interaction style.

Characterization and upgrading of bio-oils produced by rapid thermal processing

Flash pyrolysis oils have a high oxygen content. The presence of numerous and various oxygenated functions give these oils unwanted characteristics that may be improved by the elimination of oxygen by catalytic hydrotreating. This paper deals with the chemical characterization of RTP oils by liquid-liquid fractionation followed by mass spectrometric determination of the individual compounds. In a second part, the hydrodeoxygenation reactions were approached using model compounds selected on the basis of the characterization.

The CH₂Cl₂ acidic fractions of the oils are mainly composed of phenolic structures. Nevertheless, the phenolic molecules are differently substituted depending on the pyrolysis conditions: carboxyl and carbonyl groups for short residence times and methoxy groups for long residence times. All the main chemical groups present in pyrolysis oils can be eliminated using nickel-molybdenum and cobalt-molybdenum traditional hydrotreating catalysts. The reactivity, the activation energies and the products of the hydrodeoxygenation conversion of the various oxygenated groups were determined.     

How Are Social Identities Linked to Self-Conception and Intergroup Orientation? The Moderating Effect of Implicit Theories.

Social identity approaches assume that social identification affects both self-conception and intergroup orientation. The authors contend that such social identification effects are accentuated when people hold a fixed view of human character and attribute immutable dispositions to social groups. To these individuals, social identities are immutable, concrete entities capable of guiding self-conception and intergroup orientation. Social identification effects are attenuated when people hold a malleable view of human character and thus do not view social identities as fixed, concrete entities. The authors tested and found support for this contention in three studies that were conducted in the context of the Hong Kong 1997 political transition, and discussed the findings in terms of their implications for self-conceptions and the meaning of social identification.

Keratinocytes Migration Promotion,Proliferation Induction,and Free Radical Injury Prevention by 3-Hydroxytirosol

3-hydroxytyrosol (HT) is the main phenolic compound found in olive oil with known antioxidant, anti-inflammatory, and antimicrobial properties in several dermatological conditions, both when taken in the form of olive oil or pure in cosmeceutical formulations. To date, its direct effect on the wound healing process and the molecular mechanisms involved have not yet been elucidated. Thus, in the present study, we aimed to explore its effects in vitro in epidermal keratinocyte cultures focusing on the molecular mechanism implied. HT was able to induce keratinocyte proliferation in the low micromolar range, increasing the expression of cyclin dependent kinases fundamental for cell cycle progression such as CDK2 and CDK6. Furthermore, it increased cell migration through the activation of tissue remodeling factors such as matrix metalloproteinase-9 (MMP-9) protein. Then, we evaluated whether HT also showed antioxidant activity at this concentration range, protecting from H₂O₂-induced cytotoxicity. The HT prevented the activation of ATM serine/threonine kinase (ATM), Checkpoint kinase 1 (Chk1), Checkpoint kinase 2 (Chk2), and p53, reducing the number of apoptotic cells. Our study highlighted novel pharmacological properties of HT, providing the first evidence of its capability to induce keratinocyte migration and proliferation required for healing processes and re-epithelialization.     

Dating deception: Gender,online dating,and exaggerated self-presentation

This study examined how differences in expectations about meeting impacted the degree of deceptive self-presentation individuals displayed within the context of dating. Participants filled out personality measures in one of four anticipated meeting conditions: face-to-face, email, no meeting, and a control condition with no pretense of dating. Results indicated that, compared to baseline measures, male participants increased the amount they self-presented when anticipating a future interaction with a prospective date. Specifically, male participants emphasized their positive characteristics more if the potential date was less salient (e.g., email meeting) compared to a more salient condition (e.g., face-to-face meeting) or the control conditions. Implications for self-presentation theory, online social interaction, and online dating research will be discussed.

The Methyl Ester of 2-Cyano-3,12-Dioxooleana-1,9-Dien-28-Oic Acid Reduces Endometrial Lesions Development by Modulating the NFkB and Nrf2 Pathways

Endometriosis is a common gynecological disease. Here, we aimed to investigate the anti-fibrotic, anti-inflammatory, and anti-oxidative role of the methyl ester of 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid (CDDO-Me) on endometriosis. An endometriosis rat model was constructed by intraperitoneally injecting recipient rats with an equivalent of tissue from the uterus of a donor animal. Endometriosis was allowed to develop for seven days. CDDO-Me was administered on the 7th day and for the next 7 days. On day 14, rats were sacrificed, and peritoneal fluid and endometriotic implants were collected. CDDO-Me displayed antioxidant activity by activating the Nfr2 pathway and the expression of antioxidant mediators such as NQO-1 and HO-1. Moreover, it reduced lipid peroxidation and increased glutathione (GSH) levels and superoxide dismutase (SOD) activity. CDDO-Me also showed anti-inflammatory activity by decreasing the expression of pro-inflammatory cytokines in peritoneal fluids and NFkB activation. It, in turn, reduced cyclooxygenase-2 (COX-2) expression in the endometriotic loci and prostaglandin E2 (PGE2) levels in the peritoneal fluids, leading to increased apoptosis and reduced angiogenesis. The reduced oxidative stress and pro-inflammatory microenvironment decreased implants diameter, area, and volume. In particular, CDDO-Me administration reduced the histopathological signs of endometriosis and inflammatory cells recruitment into the lesions, as shown by toluidine blue staining and myeloperoxidase (MPO) activity. CDDO-Me strongly suppressed α-SMA and fibronectin expression and collagen deposition, reducing endometriosis-associated fibrosis. In conclusion, CDDO-Me treatment resulted in a coordinated and effective suppression of endometriosis by modulating the Nrf2 and NFkB pathways.     

Association of subjective health symptoms with indoor air quality in European office buildings: The OFFICAIR project

The aim of this study was to explore the association between the building-related occupants’ reported health symptoms and the indoor pollutant concentrations in a sample of 148 office rooms, within the framework of the European OFFICAIR research project. A large field campaign was performed in 37 office buildings among eight countries, which included (a) 5-day air sampling of volatile organic compounds (VOCs), aldehydes, ozone, and NO₂ (b) collection of information from 1299 participants regarding their personal characteristics and health perception at workplace using online questionnaires. Stepwise and multilevel logistic regressions were applied to investigate associations between health symptoms and pollutant concentrations considering personal characteristics as confounders. Occupants of offices with higher pollutant concentrations were more likely to report health symptoms. Among the studied VOCs, xylenes were associated with general (such as headache and tiredness) and skin symptoms, ethylbenzene with eye irritation and respiratory symptoms, a-pinene with respiratory and heart symptoms, d-limonene with general symptoms, and styrene with skin symptoms. Among aldehydes, formaldehyde was associated with respiratory and general symptoms, acrolein with respiratory symptoms, propionaldehyde with respiratory, general, and heart symptoms, and hexanal with general SBS. Ozone was associated with almost all symptom groups.     

Dietary Micronutrient Management to Treat Mitochondrial Dysfunction in Diet-Induced Obese Mice

Obesity and associated metabolic disturbances, which have been increasing worldwide in recent years, are the consequences of unhealthy diets and physical inactivity and are the main factors underlying non-communicable diseases (NCD). These diseases are now responsible for about three out of five deaths worldwide, and it has been shown that they depend on mitochondrial dysfunction, systemic inflammation and oxidative stress. It was also demonstrated that several nutritional components modulating these processes are able to influence metabolic homeostasis and, consequently, to prevent or delay the onset of NCD. An interesting combination of nutraceutical substances, named DMG-gold, has been shown to promote metabolic and physical wellness. The aim of this research was to investigate the metabolic, inflammatory and oxidative pathways modulated by DMG-gold in an animal model with diet-induced obesity. Our data indicate that DMG-gold decreases the metabolic efficiency and inflammatory state and acts as an antioxidant and detoxifying agent, modulating mitochondrial functions. Therefore, DMG-gold is a promising candidate in the prevention/treatment of NCD.
