Rats were treated with propylthiouracil (PTU) for 10-day periods beginning at different ages. Daily injections of L-thyroxine (T4) were administered concurrently with PTU to a group of rats which served as one control group. Peripheral auditory function was evaluated by the brainstem response audiometry (BSRA) technique performed at 12, 16, 25 and 120 days(More)
INTRODUCTION Acute kidney injury (AKI) in the ICU is associated with poorer prognosis. Hydroxyethylstarch (HES) solutions are fluid resuscitation colloids frequently used in the ICU with controversial nephrotoxic adverse effects. Our study objective was to evaluate HES impact on renal function and organ failures. METHODS This observational retrospective(More)
From ab initio calculations on various clusters representing the La2-xSrxCu(1)O(4) and Y(1)Ba(2)Cu(3)O(7) classes of high-temperature superconductors, it is shown that (i) all copper sites have a Cu(II)(d(9))oxidation state with one unpaired spin that is coupled antiferromagnetically to the spins of adjacent Cu(II) sites; (ii) oxidation beyond the cupric(More)
Purpose. To evaluate the epidemiology, prognosis, and management of septic shock patients hospitalized in our intensive care unit (ICU). Materiel and Methods. Five-year monocenter observational study including 320 patients. Results. ICU mortality was 54.4%. Independent mortality risk factors were mechanical ventilation (OR = 4.97), Simplify Acute Physiology(More)
This paper presents a FPGA implementation of a multiplier-based complex mixer for communication systems that require high-throughput rates and architecture scalability. The paper focuses on the design of a complex mixer that consists of a Baugh-Wooley-Adder-Tree complex multiplier and a Direct Digital Frequency Synthesizer (DDFS) based on a linear segment(More)
The equations for the magnon pairing theory of high-temperature copper-oxide-based superconductors are solved and used to calculate several properties, leading to results for specific heat and critical magnetic fields consistent with experimental results. In addition, the theory suggests an explanation of why there are two sets of transition temperatures(More)
Rats were treated with a goitrogen, propylthiouracil (PTU), from 3 days before delivery up to different ages postnatally. Peripheral auditory function was evaluated with the auditory brain-stem response (ABR) technique performed at 200 days of age. All groups of rats exposed consecutively pre- and postnatally to PTU displayed permanent auditory impairment(More)
