We employed deep UV (DUV) Raman spectroscopy for characterization of molecular photodamage in cells. 244 nm light excitation Raman spectra were measured for HeLa cells exposed to the excitation light for different durations. In the spectra obtained with the shortest exposure duration (0.25 sec at 16 µW/µm(2) irradiation), characteristic resonant Raman bands of adenine and guanine at 1483 cm(-1)...

Selenocysteine (Sec) is naturally incorporated into proteins by recoding the stop codon UGA. Sec is not hardwired to UGA, as the Sec insertion machinery was found to be able to site-specifically incorporate Sec directed by 58 of the 64 codons. For 15 sense codons, complete conversion of the codon meaning from canonical amino acid (AA) to Sec was observed along with a tenfold increase in selenop...

Differential velocity detection in the fovea was measured over a wide range of velocities (0.25-256 degrees/sec). Differential thresholds were minimum (about 6%) for intermediate velocities (4-32 degrees/sec). Velocity judgements were shown not to depend on duration judgments. The U-shaped curve relating differential velocity detection and velocity was preserved at different background levels a...

It has been proposed that filmed hangings may hold the key to a better understanding of human asphyxia, and The Working Group on Human Asphyxia was formed to systematically review and compare these video recordings. This study analyzed eight filmed hangings. Considering time 0 to represent the onset of the final hanging, rapid loss of consciousness was observed (at 8-18 sec), closely followed b...

Modulation of human cardiac mechanical and electrophysiologic function by direct stellate ganglion stimulation has not been performed. Our aim was to assess the effect of low-level left stellate ganglion (LSG) stimulation (SGS) on arrhythmias, hemodynamic, and cardiac electrophysiological indices. Patients undergoing ablation procedures for arrhythmias were recruited for SGS. A stimulating elec...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Obstructive sleep apnea (OSA) is associated with left atrial (LA) remodeling, which increases the thromboembolic risk fibrillation (AF) and recurrence after catheter ablation AF. This study aimed to assess association between severity OSA LA remodeling. Method In 126 patients AF who underwent for (male 78.4% male, 58....

در این پایان نامه مبدل های امپدانسی بطور خلاصه با عنوان (z-source converter) نامگذاری شده است. این مبدل در همه اشکال انتقال توان بصورت های dc به ac، ac به dc، ac به ac و dc به dc کابرد دارد. مبدل منبع امپدانسی از یک شبکه امپدانسی جالب بین یک منبع تغذیه و بار یا مبدل های دیگر برای دستیابی به ویژگی های منحصربفردی که در vsi و csi وجود ندارد، بهره می گیرد. در مبدل های منبع امپدانسی موانع و محدودیت ...
