Air pollution affects various aspects of human health. Here, the associations between the number of emergency department visits for circulatory and respiratory problems and ambient air pollution in Toronto, Canada, in the period between April 2004 and December 2015 were studied. The health data were linked with urban air pollution data and weather factors. The conditional Poisson regression models were built for 18 strata (sex, age group, season), 8 exposure factors (air pollutants, indexes), and their 15 lags (0-1 [...]

Cryptic balanced chromosomal aberrations can be an underlying cause of infertility. In 2003 Cockwell and coworkers highlighted the relevance of euchromatic pericentric regions of acrocentric chromosomes that may be a yet ignored genomic region hosting cryptic rearrangements. Here we offer the first follow-up study to further explore this idea. Two specific molecular cytogenetic probe sets were established to elucidate such cryptic rearrangements together with chromosomal heteromorphisms of acrocentric centromeres. [...]

The nervous system is everywhere in the body, especially in the skin. Ancient Chinese acupuncture charts show us that the nerves are all connected and can work together to promote health. This connection occurs through the brain and brain stem. It is clear that acupuncture is analgesic by inhibition of transient receptor potential cation channels in the skin [1]. The role of chemokines in pain is becoming understood. Chemokines promote pain in the skin and activate ascending neural pathways that regulate chemo [...]

Positive perceptions of pregnancy are associated with better postpartum outcomes, including stronger relationship with baby. Although better self-reported emotional availability (EA-SR) is associated with greater attachment security with infants, research has not yet explored the relationship between prenatal maternal factors and EA-SR. The aim of the study was to explore the associations between prenatal variables (adult attachment, shame, compassion) and EA-SR at 3- and 6-months postpartum. A cross-sectional surv [...]

The multi-dimensional measurement of complex biological systems and sub-systems is made possible by high-dimensional omics technologies. This frontier of research is promising for elucidating disease processes, physiological parameters, and therapeutic action mechanisms. Omics have potential merit for the integrative medicine field that is relatively early in terms of mechanistic research towards understanding the underlining therapeutic processes of mind-body interventions that show to affect multiple systems simu [...]

While numerous studies have considered forest loss factors at local scales, there is a gap of comparative quantitative regional modeling at the U.S. national level. Here, we investigated statistical relationships between gross forest cover loss (GFCL) and numerous socioeconomic, biophysical and ownership variables between two decades, the 1990s and the 2000s. A spatial error model was employed to compensate for spatial autocorrelation effects. Models from the 2000s had stronger explanatory power than the 1990s mode [...]

In the 1950’s Denham Harman proposed the Free Radical Theory of Aging whereby species lifespan and individual longevities are the consequence of free radical driven damage to biomolecules. This led to decades of research to ascertain the effect of altered antioxidant defense systems on aging and mortality in an array of species using reverse genetics and dietary manipulation. Within invertebrates, the data generally support the Free Radical Theory in that overexpression of antioxidant enzymes or dietary supplementa [...]

A surface modification approach has prepared a nanostructured organic framework connecting two metal oxide NPs. The surface modifier attached two metal oxide NPs via molecular interaction to generate modular structures of fiber, rod, or sponge materials. Thus, obtained hybrid systems have been confirmed through FT-IR, TGA, PXRD, and SEM. Metal oxides such as Fe3O4 and MgO generated mixed materials via the surface modification approach. Thus, obtained materials have been successfully used to dehydrate biomass-derive [...]

Our study sought to identify a regional explanation for declining fertility in stocks of co-occurring salmonids in the upper Trinity River, northern California, USA. We focused on evaluating the relationship between thermal variance in river water and hatchery-measured estimates of female fertility as a function of highly managed annual flow regimes. We evaluated annual and seasonal variation in volume of flow and water temperature in response to managed flows associated with annual in-river restoration actions. We [...]

Donation after circulatory death (DCD) is an increasingly used resource to alleviate chronic renal graft shortages. Organs from donors with progressively increased creatinine levels due to acute kidney injury are used, but the effects of this condition on kidney transplantation are still unclear. Ex-situ machine perfusion is emerging as a potential tool to preserve and resuscitate vulnerable grafts. We report a case of DCD kidneys discarded due to severe acute kidney injury with favorable histological Karpinski sco [...]
