cerebrovascular attack (cva) and transient ischemic attack (tia) are major causes of emergency department visits around the globe. a significant number of these patients may experience repeat attacks if left untreated. several risk stratifying scoring systems have been developed in recent years to point out the high risk patients. abcd 2 is based on age, blood pressure, clinical status, diabete...

one of the most preventable causes of mental and growth retardation is congenital hypothyroidism (ch). this study tries to investigate growth and mental outcome of patients with ch. since november 2006 and november 2007 in guilan province, north of iran, all neonates who were diagnosed with ch, evaluated for etiology of ch by laboratory follow up, thyroid sonography or scan. growth and developm...

Recent developments of the picosecond transient absorption infrared technique and its ability to elucidate the nature and kinetic behaviour of transient species formed upon pulsed laser excitation of nucleic acids are described.

Sudden catastrophic events like fires, hurricanes, tsunamis, landslides and deforestation increase population densities in habitat fragments, as fleeing animals encroach into these refuges. Such sudden overcrowding will trigger transient fluctuations in population size in the refuges, which may expose refuge populations to an increased risk of extinction. Until recently, detailed information ab...

The role of the short-lived hydrated electron (eaq–) has recently begun to be appreciated in per- and polyfluoroalkyl substances (PFAS) remediations; nevertheless, few studies date focused on short-chain PFAS, their effective defluorination been limited by an insufficient mechanistic understanding, which starts with elusive initial step eaq– reduction. Herein, this study uses pulse radiolysis c...
