Costa and Carvalho make a compelling case for the practical utility of barcoding fish. Essentially the barcode, the precise sequence of a carefully chosen few hundred base pairs of a mitochondrial gene found in all eukaryotes, is intended as a defini taxonomic criterion that can be added to the existing description of a species, but that has the enormous advantage of being applicable to any par...

in this study mercury was determined in canned tuna fish produced and distributed in iran after digestion by the standard methods of aoac. mercury contents in fish and canned tuna fish were determined by cold vapor atomic absorption spectrophotometry. the metal contents expressed in mg/kg wet weight for mercury varied from 0.017 to 0.394 (average of 0. 089) and 0.023 to 0.529 (average of 0.146)...

The research examined the relationship between 65 5- to 7-year-olds' finger gnosia, visuo-spatial working memory, and finger-use in solving single-digit addition problems. Their non-verbal IQ and basic reaction time were also assessed. Previous research has found significant changes in children's representational abilities between 5 and 7 years. One aim of the research was to determine whether ...

conclusions our findings revealed that the zfn technology could be employed to overcome ampicillin resistance by the targeted disruption of the ampicillin resistance gene, which leads to inactivation of β-lactam synthesis. therefore, zfn technology could be engaged to decrease the antibiotic resistance issue with the construction of a zfn archive against different args. to tackle the resistance...

CONTEXT Due to its cardiovascular benefits, fish consumption is widely encouraged among older Americans. However, this fast-growing population is at increased risk of cognitive impairment and may be particularly sensitive to methylmercury, a neurotoxicant found in fish. OBJECTIVE To describe associations of blood mercury levels with neurobehavioral test scores in an urban adult population. ...

OBJECTIVE Microvascular dysfunction is suggested to be a marker of common pathophysiological mechanisms in the development of insulin resistance, cardiovascular diseases, and type 2 diabetes mellitus. Given the established relationship of diet with the macrovascular disease, the aim of this study was to investigate for the first time the possible associations between dietary patterns and microc...

A healthy 42 year old woman presented with a tender red-bluish fluctuating swelling of the dorsum of her left hand, which had been present for five weeks. The swelling was not warm and originated from one or two extensor tendon sheaths (fig 1). There had not been any previous trauma. Treatment with trimethoprim/sulfamethoxazole by the general practitioner was not successful. Until one year earl...

Elasmobranchs, the taxonomic group comprising sharks, skates and rays, play important roles in society and marine ecology but several species in this subclass are under threat.  This collection aims to be an open access hub for articles concerning all areas of elasmobranch biology and conservation. The collection is indefinitely open to further submissions and so will continue to grow as additi...
