Alterations in cerebellar protein synthesis in propylthiouracil-induced hypothyroid rats
… of hormonal deprivation: early in development (PTU 1), late in development (PTU 2), and continual deprivation (PTU 3). The effects of these deprivations on some aspects of the synthesis of two proteins known to be affected by T3, apolipoprotein E (apo E) and transferrin (T1), were investigated. …

Basal Release of Endothelium-derived Nitric Oxide in Thyropathologic Rat Aorta
… determined for hyperthyroid (TRX), hypothyroid (PTU), and euthyroid control (CON) rats. All three measurements were elevated in TXX animals, while PTU rats were determined to have decreased measurements when compared with CON and TRX rats. Animals were sacrificed by either cervical dislocation or …

Thyroid Hormones and the Onset of Hibernation in the 13-Lined Ground Squirrel, Spermophilus Tridecemlineatus
… (n=7 per treatment) were given propylthiouracil (PTU: 0.01%) in their drinking water to block thyroid function, in combination with a long photoperiod or naturally decreasing photoperiod, and either cold (10°C) or warm (25°C) temperature. Control animals (n=7-9 per treatment) were kept in the same …

Characterization of 5-Hydroxytryptamine-Evoked Isometric Contractile Responses in Aortic Vascular Smooth Muscle in Thyropathological Rats
… rings from hyperthyroid (TRX),hypothyroid (PTU), and euthyroid control (CON) rats were mounted in climate controlled tissue baths and subjected to isometric contraction experiments. The endothelium was removed from some rings (denuded) while others were left intact. All rings were initially …

The Effects of Prenatally Induced Hypothyroidism of the Neural Development and Problem Solving Ability of Maturing Hypothyroid Rats
… pregnant female rats with propylthiouracil (PTU), and then to evaluate the problem solving ability and the changes in the brain of the hypothyroid offspring. Procedure. Three 8-day sperm-positive female rats were given PTU (0.01 gm/100 ml) water from day 15 of gestation until day 7 …

Computer Vision Tracking of sUAS From a Pan/Tilt Platform
… (COTS) cameras and a pan-tilt unit (PTU), along with custom developed code, is developed for the purpose of continuously pointing at and tracking the motion of a sUAS in flight. Mixtures of Gaussians Background Modeling (MOGBM) is used to track the motion of the sUAS in frame and …

Regulation of LKB1-STRAD-MO25 Complex Expression and Activation of AMPK in Skeletal Muscle by Thyroid Hormone
… weeks, and in rats given 0.01% propylthiouracil (PTU) in drinking water for 4 weeks. The relative expression of LKB1, MO25, and STRAD, as well as PGC-1α, increased in the soleus of thyroid hormone treated rats vs. the controls. MO25 mRNA increased with thyroid hormone treatment, and STRAD mRNA …

Determinación de la exposición a ditiocarbamatos en el sector floricultor en la Sabana de Bogotá y en Rio Negro-Antioquia Colombia
… Los niveles de del metabolito Propilentiourea (PTU) en orina fueron en promedio al final de la jornada laboral de 2,0 mg/l ±3,4. La mayor variación de las concentraciones de PTU estuvo en el grupo de riesgo medio. Conclusión: Se evidenció el uso de plaguicidas extremada y altamente tóxicos …

Extrathyroidal thyroid hormone activation in ring doves
… 5’D activity was completely inhibited by 1.0 mM PTU and 50% inhibited by the addition of 18.0 μM thyroxine (T4) in the presence of 4.0 μM rT3. Activity was maximal at pH 8.04 and at 37.5 C. The K<sub>m</sub> of the enzyme did not change throughout development (1 day prehatch to adult). The 5’D …

Stochastic Optimization approaches for trading on financial and energy markets
… On the other hand, at each Program Time Unit (PTU) BRPs must also offer their available capacity under the form of bids. In this paper, a bidding strategy to the double-sided market is described, where the risk is minimized and all the constraints are fulfilled. The algorithms devised are …

Fat deposition in relation to sexual maturation of Japanese quail
… at sexual maturity, by feeding diets containing PTU (4-phenyl-2 thiouracil), by imposing a daily photoperiod (IP) of four hours, by the subcutaneous implantation of estrogen to females and testosterone to males, and by the intramuscular injection of turkey growth hormone and anti-sera to turkey …
