Decoding the cryptic origins of colon cancer.
in the endocrinology area after the discovery of its secretion from the adipose tissue. The aim of the study is to investigate the leptin levels in obese women in whom type 2 diabetes mellitus were present or absent. Materials and methods : Thirty-five obese women with type 2 diabetes mellitus (group 1) and 34 obese women without type 2 diabetes mellitus (group 2) were enrolled in the study. In...
متن کاملFactors affecting methylmercury biomagnification by a widespread aquatic invertebrate predator, the phantom midge larvae Chaoborus.
MeHg biomagnification by the phantom midge Chaoborus in relation to MeHg concentrations in their prey and its migratory behavior was investigated in two Canadian Precambrian Shield lakes. Three Chaoborus species with contrasted migratory behavior were collected in a fishless and a fish-inhabited lake. All species accumulated MeHg through their ontogenic development. In the lake inhabited by fis...
متن کاملPhantom Limbs, Neuroprosthetics, and the Developmental Origins of Embodiment.
Amputees who wish to rid themselves of a phantom limb must weaken the neural representation of the absent limb. Conversely, amputees who wish to replace a lost limb must assimilate a neuroprosthetic with the existing neural representation. Whether we wish to remove a phantom limb or assimilate a synthetic one, we will benefit from knowing more about the developmental process that enables embodi...
متن کاملRapid swimming and escape movements in the aquatic larvae and pupae of the phantom midge Chaoborus crystallinus.
Rapid locomotion in the aquatic larvae and pupae of the phantom midge Chaoborus crystallinus was analysed. A 10-mm long larva moved sporadically by rapidly curling into a tight circle and then unfurling. The most common movement (70% of all movements) was a body rotation of 332±22 deg (mean ± s.d.) that lasted 63±19 ms and reached a peak velocity of 0.07±0.02 m s(-1). If the head unfurled earli...
متن کاملCompetition between protons and cadmium ions in the planktonic food chain leading to the phantom midge Chaoborus
Cadmium concentrations in the phantom midge Chaoborus can be related to those of the free Cd ion, Cd21, in lakewater provided that the competitive influence of H on Cd uptake sites is considered. Because this predator takes up its Cd from plankton, competition between H and Cd21 ions could take place at several levels in the food chain to which this insect belongs. To identify at which trophic ...
