This study was conducted to examine the possibility of using construction solid waste (CSW), an inevitable by-product of the construction and demolition process, as the main substrate in a laboratory scale multi-stage constructed wetland system (CWs) to improve phosphorus (P) removal from secondary sewage effluent. A tidal-flow operation strategy was employed to enhance the wetland aeration. Th...
Cerebral salt wasting (CSW) is a syndrome of hypovolemic hyponatremia caused by natriuresis and diuresis. The mechanisms underlying CSW have not been precisely delineated, although existing evidence strongly implicates abnormal elevations in circulating natriuretic peptides. The key in diagnosis of CSW lies in distinguishing it from the more common syndrome of inappropriate secretion of antidiu...
The term cerebral salt wasting (CSW) was introduced before the syndrome of inappropriate antidiuretic hormone secretion was described in 1957. Subsequently, CSW virtually vanished, only to reappear a quarter century later in the neurosurgical literature. A valid diagnosis of CSW requires evidence of inappropriate urinary salt losses and reduced "effective arterial blood volume." With no gold st...
Hyponatremia secondary to the Syndrome of Inappropriate Anti-Diuretic Hormone (SIADH) secretion is commonly observed in patients with various neurological disorders. Cerebral Salt Wasting (CSW) resulting in hyponatremia is also an infrequent occurrence in some patients with neurological disorders. Confusion in differentiating CSW from SIADH may arise since both results in similar electrolyte di...
Vertebrate Src can be activated by specific mutations to become oncogenic. Analogous mutations in Drosophila Src64 (DSrc) induce abnormal differentiation of photoreceptor cells when expressed ectopically in the developing Drosophila adult eye. We have investigated the roles that the adapter protein, Downstream of receptor kinases (Drk), and the SH2 domain-containing tyrosine phosphatase, Corksc...
Data envelopment analysis (DEA) does not provide more information about the efficient decision making units (DMUs). A method to rank efficient DMUs is common set of weights (CSW). This research proposes some simple methods to find common set of weights CSW for the performance indices of DEA efficient DMUs. These methods use the results of the standard DEA models to determine the CSW. Unlike the...
BACKGROUND Historically, hyponatremia in patients with varying brain diseases was termed cerebral salt wasting. Hyponatremia secondary to CSW was reported to be a distinct entity from SIADH, with the distinguishing feature of decreased extracellular fluid volume. Brain natriuretic peptide, a peptide with natriuretic, vasorelaxant, and aldosterone-inhibiting properties, was recently implicated i...
Mutations in the PTPN11 gene, which encodes the protein tyrosine phosphatase SHP-2, causes Noonan syndrome (NS), an autosomal dominant disorder with pleomorphic developmental abnormalities. Certain germline and somatic PTPN11 mutations cause leukemias. Mutations have gain-of-function (GOF) effects with the commonest NS allele, N308D, being weaker than the leukemia-causing mutations. To study th...
SUMMARY Hyponatraemia is the most commonly encountered electrolyte disturbance in neurological high dependency and intensive care units. Cerebral salt wasting (CSW) is the most elusive and challenging of the causes of hyponatraemia, and it is vital to distinguish it from the more familiar syndrome of inappropriate antidiuretic hormone (SIADH). Managing CSW requires correction of the intravascul...
One-loop maximal helicity violating (MHV) amplitudes in N = 4 super YangMills (SYM) theories are analyzed, using the prescription of Cachazo, Svrcek, and Witten (CSW). The relations between leading Nc amplitudes An;1 and sub-leading amplitudes An;c obtained by the CSW prescription are found to be identical to those obtained from conventional field theory calculations. Combining with existing re...
