Medications, epilepsy and climate change: Added layers of complexity

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Climate change—the global crisis with pervasive health impacts—has adverse consequences for people with epilepsy (PWE) who have low quality of life due to poor seizure control, socioeconomic disadvantages and comorbidities. This review focuses on the potential effects of climate change on the pharmacological characteristics of antiseizure medications ...

Mechanisms affecting the overturning response in global warming simulations [PDF]

open access: yes, 2005
Climate models used to produce global warming scenarios exhibit widely diverging responses of the thermohaline circulation (THC). To investigate the mechanisms responsible for this variability, a regional Atlantic Ocean model driven with forcing ...

Brazilian Biomes as Promising Resources of Rhodotorula Yeasts for the Biotechnological Production of Carotenoids

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Yeasts belonging to the genus Rhodotorula are capable of synthesizing carotenoids, such as β‐carotene, γ‐carotene, torulene, torularodine, and astaxanthin. These carotenoids have been shown to offer health benefits to humans, such as immune system strengthening and a reduced risk of chronic degenerative diseases.

Season of birth modifies puberty in female and male goats raised under subtropical conditions

open access: yesAnimal, 2007
In seasonal goats and sheep breeds, onset of puberty is modified by the season of birth. As adult does and bucks from subtropical Mexico display seasonal variation in their reproductive behaviour, this study was carried out to determine the effect of ...
