mehg and total mercury concentrations were determined in the muscle tissues of four fish species (cyprinus carpio, rutilus frisii, carassius auratus and esox lucius) from anzali wetland (guilan, iran). fish with the highest amount of mehg was selected to determine the thermodynamic parameters of mehg extraction. the extractions process was performed in the range of temperatures 331.15 to 367.15...

when stretcher came to unit and i was put in my bed, nursing personnel of surgical ward said to me hello. i had seen their face from yesterday night when they were transferring patients from emergency ward to this unit.  in that time, i had the role of emergency ward assistant manager. today, i am a weak patient that even is unable for smallest movement. cause of my admission to hospital is mus...

Loss of functional capacity of skeletal muscle is a major cause of morbidity in patients with a number of acute and chronic clinical disorders, including sepsis, chronic obstructive pulmonary disease, heart failure, uremia, and cancer. Weakness in these patients can manifest as either severe limb muscle weakness (even to the point of virtual paralysis), respiratory muscle weakness requiring mec...

IMPORTANCE Free muscle transfer innervated by a cross-facial nerve graft represents the criterion standard for smile reconstruction in facial paralysis. If primary reconstruction fails, a second muscle transfer is usually needed. Herein, we investigated the possibility of avoiding a second free muscle transfer by in situ coaptation of the gracilis muscle to the masseteric nerve. OBSERVATIONS ...

BACKGROUND Despite the most heroic efforts, sometimes free flaps fail. Perforator free flaps are not invincible and can suffer the same fate. The real challenge is how to decide what is the next best choice for achieving the desired outcome. METHODS Over the past decade, 298 free perforator flaps were used in our institution. Total failure occurred in 16 patients, and partial failure requirin...

We find that the high temperature limit of the free energy per unit length for the rigid string agrees dimensionally with that of the QCD string (unlike the Nambu-Goto string). The sign, and in fact the phase, do not agree. While this may be a clue to a string theory of QCD, we note that the problem of the fourth derivative action makes it impossible for the rigid string to be a correct descrip...
