The polycyclic aromatic compounds (PAC) produced from the pyrolysis of a bituminous coal at temperatures of 1125 to 1425 degrees K prove to be mutagenic to S. typhimurium, both in the presence and in the absence of postmitochondrial supernatant (PMS) prepared from Aroclor 1254-induced rat liver. Mutagenicity of the PAC samples measured in the absence of PMS exhibits little dependence on pyrolys...

PURPOSE We describe the feasibility of partial arterial clamping (PAC) during robot-assisted partial nephrectomy (RAPN). PATIENTS AND METHODS We undertook a retrospective study of five patients who underwent PAC vs 17 who underwent complete hilar clamping (CHC). Estimated blood loss (EBL), transfusion rate, operative/console time, warm ischemia time (WIT), pathology, and postoperative glomeru...

When the opsonization of various Pseudomonas aeruginosa strains--PAC 1, its O-chain-deficient mutant PAC 605, and an intermediate strain, P14--was measured either directly by determination of the amount of C3b attached to the bacterial surface or indirectly by assessing phagocytosis by human polymorphonuclear leukocytes and the responses of chemiluminescence, it was demonstrated that PAC 1 was ...

Auditory verbal hallucinations (AVHs) are a subjective experience of "hearing voices" in the absence of corresponding physical stimulation in the environment. The most remarkable feature of AVHs is their perceptual quality, that is, the experience is subjectively often as vivid as hearing an actual voice, as opposed to mental imagery or auditory memories. This has lead to propositions that dysr...

BACKGROUND Identification of genes that are causally implicated in oncogenesis is a major goal in cancer research. An estimated 10-20% of cancer-related gene mutations result in skipping of one or more exons in the encoded transcripts. Here we report on a strategy to screen in a global fashion for such exon-skipping events using PAttern based Correlation (PAC). The PAC algorithm has been used p...

BACKGROUND Complications of abortion are one of the leading causes of maternal mortality worldwide, along with hemorrhage, sepsis, and hypertensive diseases of pregnancy. In Afghanistan little data exist on the capacity of the health system to provide post-abortion care (PAC). This paper presents findings from a national emergency obstetric and neonatal care needs assessment related to PAC, wit...

We prove that for almost all σ ∈ G(Q)e the field Q̃(σ) has the following property: For each absolutely irreducible affine variety V of dimension r and each dominating separable rational map φ: V → Ar there exists a point a ∈ V (Q̃(σ)) such that φ(a) ∈ Zr. We then say that Q̃(σ) is PAC over Z. This is a stronger property then being PAC. Indeed we show that beside the fields Q̃(σ) other fields which ...

This study is to investigate on the long term performance of submerged membrane adsorption hybrid system (SMAHS) for organic matter removal from synthetic wastewater representative of biologically treated wastewater using low dose of powder activated carbon (PAC). A simple periodic backwash system is used to declog the hollow fiber membrane. In this reactor, bioreaction takes place due to the g...

Pollution in river water affects human, plant and animal health activities, its removal using chemical coagulants is a huge concern. This study aims to reduce turbidity COD pollutants through coagulation-adsorption process by Tacca leontopetaloides biopolymer flocculant (TBPF) powder activated carbon (PAC). In coagulation experiment, TBPF dosages were varied evaluate the effect on Bioblock floc...
