Hibernation in small mammals is a highly regulated process with periods of torpor involving drops in body temperature and metabolic rate, as well as a general decrease in neural activity, all of which proceed alongside complex brain adaptive changes that appear to protect the brain from extreme hypoxia and low temperatures. All these changes are rapidly reversed, with no apparent brain damage occurring, during the short periods of arousal, interspersed during torpor-characterized by transitory and partial rewarming and activity, including sleep activation, and feeding in some species. The orexins are neuropeptides synthesized in hypothalamic neurons that project to multiple brain regions and are known to participate in the regulation of a variety of processes including feeding behavior, the sleep-wake cycle, and autonomic functions such as brown adipose tissue thermogenesis.

A growing trend is to develop low-toxicity formulations based on biodegradable components. In this sense, vegetable oils structured with nanomaterials could be an alternative to mineral or synthetic oils for sustainable fluid formulations.

Vertebral osteomyelitis, or spondylodiscitis, is a rare disease with increasing prevalence in recent years due to a greater number of spinal surgical procedures, nosocomial bacteraemia, an aging population and intravenous drug addiction. Haematogenous infection is the most common cause of spondylodiscitis. We report a 47-year-old man diagnosed with Escherichia coli spondylodiscitis.

A simple blind trial was conducted to compare the effect of 2 forms of iron fortification and assess the changes in hemoglobin and iron status indices among preschool children from rural communities.
Methods: Hemoglobin was evaluated in 47 children aged 3-6 years old.
Purpose: To monitor the rise in consumption of antiparkinson drugs as well as the prevalence of this illness in the Basque Autonomous Community (Spain) over a period of 13 years (1992-2004).
Methods: A retrospective population-based study where consumption of antiparkinson drugs was conducted using data obtained from the ECOM (Especialidades Consumo de Medicamentos) database of the Spanish Ministry of Health, which contains the number of prescriptions filled in community pharmacies and charged to the National Health System. The results are expressed as DID, Defined daily doses per 1000 inhabitants per day.
Several non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with liver damage. The aim of this study was to compare proportions of hepatic adverse drug reaction reports associated with NSAIDs in France and Spain. Information from the Spanish and French pharmacovigilance databases were used from 1982 to 2001.

Out of 24 identified PFGE profiles, a major clone was detected in 19% of strains from humans, 52% from food, and 62% from swine. This clone (clone 1) was isolated from pork products, suggesting swine as its source.

A high proportion of this consumption may be due to the use of those drugs as gastroprotective agents when co-prescribed with non-steroidal anti-inflammatory drugs (NSAIDs). The aim of this study was to learn how these treatments are being used: the prevalence of use, the type of drug and the main features of patients.
