Poly(A) polymerase (PAP) plays an essential role in polyadenylation of mRNA precursors, and it has long been thought that mammalian cells contain only a single PAP gene. We describe here the unexpected existence of a human PAP, which we call neo-PAP, encoded by a previously uncharacterized gene. cDNA was isolated from a tumor-derived cDNA library encoding an 82.8-kDa protein bearing 71% overall...
Study objectives To examine the usability of positive airway pressure (PAP) devices and its association with PAP adherence among older adults with sleep-disordered breathing. Methods We mailed questionnaires to patients aged ≥65 years prescribed PAP therapy during the prior 36 months from two large healthcare systems. Survey participants completed the Usability of Sleep Apnea Equipment-Positi...
In a previous study, preparations of polyclonal antibodies (PAP) against Fusobacterium necrophorum (PAP-Fn) or Streptococcus bovis (PAP-Sb) were successful in decreasing ruminal counts of target bacteria and increasing ruminal pH in steers fed high-grain diets. The objective of this study was to evaluate the effects of feeding PAP-Fn or PAP-Sb on performance, carcass characteristics, and rumina...
Human prostatic acid phosphatase (PAP) isoenzymes, designated PAP-A and PAP-B, were isolated from human seminal plasma by sequential affinity chromatography on concanavalin A and L(+)-tartrate, a classic inhibitor of PAP. Both the major PAP-A and the minor PAP-B isoenzymes exhibited a similar molecular mass (100 and 105 kDa respectively), multiple pI values (5.05-5.35 and 5.05-5.12), and substr...
In this work, we report the thermal kinetics, thermodynamics, and decomposition mechanism of AP-based molecular perovskite energetic materials estimate their safety performance. Typical materials, (H 2 dabco)[NH 4 (ClO ) 3 ] (DAP-4), pz)[NH ](PAP-4), mpz)[NH ](PAP-M4), hpz)[NH (PAP-H4), were synthesized characterized. These studied using differential scanning calorimetry (DSC). The results show...
Background: Tumor cells need food and oxygen supply for growth and division. Therefore one of the most promising areas of cancer therapy focuses on using agents that inhibit tumor angiogenesis. Inhibition of angiogenesis prevents cell growth, division and metastasis. Previous studies showed that plasminogen related Protein-B has an anti-tumor activity in mice. This protein has a high level of h...

Background and Objectives: Cervical cancer is one of the most important female reproductive system diseases. The aim of this study was to estimate the prevalence of abnormal Pap smears of pregnant females in public health centers and hospitals of Hamadan. Materials and Methods: In a retrospective study, 36046 Pap smears of females was extracted from the records referred to government health ...
objective: the pap smear is a reliable, inexpensive and effective screening test for cervical cancer; the second most common cancer among women worldwide. we aimed to determine women’s knowledge, attitudes and practice towards pap smear and barriers for the screening in a public hospital. materials and methods: this study, was carried out on 350 outpatient married women reffering for a visit a...
