background and objective: the outcome of hepatitis b virus (hbv) infection may be influenced by host factors like human leukocyte antigen (hla). we have investigated hla-a and drb1 alleles in patients with persistent hepatitis b infection compared to subjects who had spontaneously recovered from hbv infection. to complete the findings of this study we performed another survey in certain hla all...

C++ objects of types that have virtual functions or virtual base classes contain volatile (‘‘memory’’)pointers. We call such pointers ‘‘hidden pointers’ because they were not specified by the user. If such C++objects are made persistent, then these pointers become invalid across program invocations. Weencountered this problem in our implementation of O++, which is a database languag...

The notion of persistency, based on the rule “no action can disable another one” is one of the classical notions in concurrency theory. In this paper, we deal with arbitrary place/transition nets, but concentrate on their persistent computations. It leads to an interesting decision problem: Is a given marking reachable with a persistent run? In order to study the persistent-reachability problem...

Although many studies have investigated the requirement for CD4(+) T cell help for CD8(+) T cell responses to acute viral infections that are fully resolved, less is known about the role of CD4(+) T cells in maintaining ongoing CD8(+) T cell responses to persistently infecting viruses. Using mouse polyoma virus (PyV), we asked whether CD4(+) T cell help is required to maintain antiviral CD8(+) ...

OBJECTIVE To empirically identify latent classes of service members according to persistent postconcussive symptom patterns and to characterize the identified classes relative to other postdeployment variables including posttraumatic stress disorder (PTSD) and mild traumatic brain injury (TBI) screening results. Such comparisons may directly inform policy regarding these routine assessments and...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether patients with liver cirrhosis have acceptable outcomes after undergoing cardiac surgery. Altogether 97 papers were found using the reported search, of which nine presented the best evidence to answer the clinical question. The author, year, journal, country of study, study...

Only a small proportion of women who are exposed to infection with high-risk human papillomavirus (HR-HPV) progress to persistent infection and develop cervical cancer (CC). The immune response and genetic background of the host may affect the risk of progression from a HR-HPV infection to lesions and cancer. However, to our knowledge, no studies has been conducted to evaluate the relationship ...

although current guidelines place single leukotriene receptor antagonists use as a therapeutic option in mild persistent asthma, there is still uncertainty about its place. in this study efficiency of montelukast monotherapy in children with moderate persistent asthma was evaluated. children (age 6 to 16) with persistent moderate asthma were treated prospectively with budesonide combined with m...
