While complete neck clipping of ruptured cerebral aneurysms prevents rerupture, recurrent subarachnoid hemorrhage (SAH) due to the rupture of an aneurysm at the same sites of the previous aneurysm may occur, even if no residual neck was detected during and after neck clipping. We present the cases of 3 patients with recurrent SAH due to regrowth after neck clipping of aneurysms at the anterior ...

This paper work focuses on performance analysis of PAPR reduction of orthogonal frequency division multiplexing (OFDM) using amplitude clipping & filtering based design. Now a days one of the most proficient multi-carrier transmission techniques widely used today is orthogonal frequency division multiplexing (OFDM) which has been implemented by the next generation wireless communication technol...

Orthogonal Frequency Division Multiplexing (OFDM) is one of the Strong candidate for Transmission of high data rate due to Multicarrier Modulation. One of the challenging Issue of OFDM is its high Peak to Average Power Ratio (PAPR or PAR). This Paper discusses different PAPR Reduction techniques in OFDM. The Classical Clipping, Selective Mapping, Tone reservation and Partial Transmit sequence T...

Dear Sir, We describe a patient with progressive locked-in syndrome due to a giant interpeduncular basilar aneurysm that initially underwent coiling and eventually clipping. The case is unusual because the locked-in syndrome was caused by severe midbrain compression rather than an ischemic infarction of the basis pontis, had a gradual rather than abrupt onset and was accompanied by vertical rat...

MATERIALS AND METHODS: Using the NIS, we evaluated outcomes of patients treated for unruptured aneurysms in the United States from 2001 to 2007. Hospitalizations for clipping or coiling of unruptured cerebral aneurysms were identified by cross-matching ICD codes for diagnosis of unruptured aneurysm with procedure codes for clipping or coiling of cerebral aneurysms. Mortality and morbidity, meas...

Chromatin in cervical cancer (CC) undergoes chemical and structural changes that alter the expression pattern of genes. Recently, a potential mechanism, which regulates gene expression at transcriptional levels is the proteolytic clipping of histone H3. However, until now this process in CC has not been reported. Using HeLa cells as a model of CC and human samples from patients with CC, we iden...

Sympathovagal balance and baroreflex control of heart rate (HR) were evaluated during the development (1 and 4 wk) of one-kidney, one-clip (1K1C) hypertension in conscious mice. The development of cardiac hypertrophy and fibrosis was also examined. Overall variability of systolic arterial pressure (AP) and HR in the time domain and baroreflex sensitivity were calculated from basal recordings. M...

Endoscopic clips have been used mainly for control of gastrointestinal (GI) bleeding and occasionally for closure of GI perforations. However, closure of spontaneous esophageal perforation (Boerhaave's syndrome) by clipping has not been reported. We described successful non-surgical closure of spontaneous esophageal perforation by endoscopic clipping in a patient with bilateral pyopneumothorax ...
