Background & Aims: While iodine is an essential element for the synthesis of thyroid hormones, epidemiological studies have showed that excessive iodine intake leads to autoimmune thyroid diseases, with an unknown mechanism. Previous studies have showed disturbance in the circulating cytokines could lead to autoimmune diseases. To determine the role of iodine in cytokine production and devel...

disturbances in fibromyalgia syndrome: relationship to pain and depression. Sleep disturbance is a widely reported and debilitating concomitant of fibromyalgia syndrome (FMS) and plays a pivotal role in exacerbating patients reporting of symptoms. Bigatti and colleagues report a longitudinal study that examined self-reported sleep, pain, depression and physical functioning at baseline in FMS pa...

Spatial and temporal variability in cone production may influence post-disturbance succession, yet it is not well understood. We sampled 15year old lodgepole pine (Pinus contorta var. latifolia) stands (n = 16) that regenerated naturally after the 1988 Yellowstone fires and varied in stand density (566–545,200 stems ha ) and elevation to quantify and explain variation in cone production. Among ...

Land-use conversion into bioenergy crop production can alter litter decomposition processes tightly coupled to soil carbon and nutrient dynamics. Yet, litter decomposition has been poorly described in bioenergy production systems, especially following land-use conversion. Predicting decomposition dynamics in postconversion bioenergy production systems is challenging because of the combined infl...

Gelatin given by vein to doubly depleted dogs (anemic and hypoproteinemic) gives no immediate toxic response, no anaphylactoid reactions, and may contribute something to the building of new hemoglobin and plasma protein. Gelatin given by vein during 1 to 2 weeks (total 3 to 17 gm. per kilo) usually causes serious disturbances-inhibition of blood protein production, signs of intoxication, much w...

Background: Flour is one of the most important food sources, therefore it must be kept healthy and clean. As a potential pest control modality, we aimed to examine whether flour irradiation is a feasible tool to eradicate Tribolium confusum adults from infected flour considering probable health effects of infested flour consumption. Materials and Methods: unirradiated and irradiated flour were ...

Bottom trawling causes widespread disturbance of sediments in shelf seas and can have a negative impact on benthic fauna. We conducted a large-scale assessment of bottom trawl fishing of benthic fauna in different habitats, using a theoretical, size-based model that included habitat features. Species richness was estimated based on a generalized body mass versus species richness relationship. T...

The sequence in which disturbance events occur has the potential to affect the structure of ecological communities, but its role has been generally overlooked. Most disturbance studies have focused on the frequency or intensity of disturbance, probably reflecting the influence of the intermediate disturbance hypothesis. To investigate the effects of disturbance sequence on community structure, ...

Polycyclic aromatic hydevrepocarbons (PAHs), which are ubiquitous in the air, are present as volatile and particulate pollutants that result from incomplete combustion. Most PAHs have toxic, mutagenic, and/or carcinogenic properties. Among PAHs, benzo[a]pyrene (B[a]P) and dimethylbenz[a]anthracene (DMBA) are suspected endocrine disruptors. The testis is an important target for PAHs, yet effects...

SEKINE, T. and SHIRATORI, T. Significance of Local Circulatory Disturbance in the Experimental Production of Gastric Ulcer. Tohoku J. exp. Med ., 1974, 114 (2), 121-130 Experimental gastric ulcers were produced by ligating gastric vessels accompanied with or without histamine administration. A total of 62 adult mongrel dogs were divided into five groups, and intramuscular injection of histamine...
