in order to simultaneously improve wet and dry strengths of paper and decrease environmental issues related to the wet strength resins, in this study effect of application method of wet strength additives on paper properties was investigated. wet strength resins were applied in four methods including spraying an aqueous glyoxal solution on to the surface of wet paper, addition of aminated polya...

The aryl hydrocarbon receptor (AhR) is targeted by ubiquitination for degradation by the proteasome shortly after its activation by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In silico screening identified p-anilinoaniline (pAA) as a putative inhibitor of an E2 ligase that partners with an E3 ligase implicated in AhR ubiquitination. We investigated whether pAA could modify AhR-dependent activa...

P ulmonary artery (PA) aneurysms (PAAs) are rare and infrequently diagnosed. Deterling and Clagett 1 discovered 8 cases of PAAs in 109 571 consecutive postmortem examinations. PAAs generally occurred in a younger age group than aortic aneurysms with an equal sex incidence. 2 Eighty-nine percent of all PAAs were located in the main PA, whereas only 11% were located in the pulmonary branches. 3 W...

Here, we report a new case with chromosome 22q11 deletion and cardiac anomaly diagnosed prenatally by echocardiography. Fluorescence in situ hybridization (FISH) analysis demonstrated a heterozygous deletion at 22q11.2. Echocardiography revealed ventricular septal defect, pulmonary atresia, and aneurysm of the main pulmonary artery and its branches. Pulmonary artery aneurysm (PAA) is rarely see...

In tissue culture phosphonoacetic acid (PAA) specifically inhibited DNA synthesis of human cytomegalovirus (CMV), murine CMV, simian CMV, Epstein-Barr virus, and Herpesvirus saimiri. Fifty to one hundred micrograms per milliliter PAA completely inhibited viral DNA synthesis with no significant damage to host cell DNA synthesis. In vitro DNA polymerization assays showed that 10 μg/ml of PAA spec...

It is known that daily polyaspartic acid (PAA) protects the kidney from gentamicin nephrotoxicity in a standardized rat model despite marked cortical accumulation of the aminoglycoside. The present experiments address the duration of PAA protection. When administered every other day, PAA provided functional and histologic protection against gentamicin-induced toxicity. A stepwise reduction in n...

Abstract Privacy-enhancing techniques and protocols for data aggregation analytics in wireless networks require the development of novel methods efficient privacy-preserving computation distributed queries with protection outcomes from active attackers. Previous approaches to secure incur significant communication overhead cannot be applied big data. This paper proposes two solutions problem ou...
