Anal cancer is one of the leading causes of death in non-AIDS defining cancers. Most of these cancers are associated with high risk HPV infection. So far, the prevalence and the significance of anal HPV infection have not been studied in the Hungarian MSM population. The main objective of our study was to determine the prevalence and associated risk factors of HPV-infection in the Hungarian MSM community, particularly in HIV-infected MSM. Out of 109 examinations 92 samples (80 HIV-infected and 12 HIV-negative MSM) were evaluated for both cytological abnormalities and HPV genotyping PCR...

Polyphenol oxidase (PPO) is believed to play a role in plant growth, reproduction, and resistance to pathogens and pests. PPO causes browning of grains in cereals. In this study, genetic mapping of sorghum grain for phenol color reaction (PHR) was performed using a recombinant inbred line population. Only one locus was detected between SSR markers SM06072 and Xtxp176 on chromosome 6. Two linked orthologous genes (Sb06PPO1 and Sb06PPO2) within the mapped region were discovered and cloned. Transformation experiments using Nipponbare (a PHR negative rice cultivar) showed that Sb06PPO1 from LTR108 and two Sb06PPO2 alleles from both varieties could complement Nipponbare, whereas Sb06PPO1 from 654 could not...

Montmorillonite (MMT) was added to silicone rubber (SR) to improve the ablation resistance of the silicone. Following this, different quantities of silicon carbide whiskers (SiCw) were incorporated into the MMT/SR to yield a hybrid, ablative composite. The tensile strength and elongation at break of the composite increased after the addition of MMT. The ablation test results showed that MMT helped to form a covering layer by bonding with the silica and other components on the ablated surface. The linear and mass ablation rates exhibited decreases of 22...

István Zoltán Halász, Tamás Bárány
In this work, the effect of mixing temperature (Tmix) on the mechanical, rheological, and morphological properties of rubber/cyclic butylene terephthalate (CBT) oligomer compounds was studied. Apolar (styrene butadiene rubber, SBR) and polar (acrylonitrile butadiene rubber, NBR) rubbers were modified by CBT (20 phr) for reinforcement and viscosity reduction. The mechanical properties were determined in tensile, tear, and dynamical mechanical analysis (DMTA) tests. The CBT-caused viscosity changes were assessed by parallel-plate rheometry...

INTRODUCTION: Persistent infection of human papillomavirus is known to cause cervical intraepithelial neoplasia or cancer in the cervix uteri and other HPV-associated cancers in different localization. Based on epidemiological and biological data, principally the high risk HPV is responsible for development of cervical these cancers. However, we have no information about the frequently distribution of different HPV types and what is the correlation between the HPV types and cytological diagnosis in cervical intraepithelial neoplasia (CIN)...

BACKGROUND: Parastomal hernia repair (PHR) remains a challenge with no optimal repair technique. During retromuscular hernia repair, traversing the stomal conduit through the abdominal wall can result in angulation and compression. Widening of traditional cruciate incisions in mesh and/or fascia likely contributes to recurrences. To address these pitfalls, the Stapled Transabdominal Ostomy Reinforcement with Retromuscular Mesh (STORRM) technique utilizing a circular stapler was developed...

BACKGROUND: Personal Health Records (PHR) systems provide individuals with access and control over their health information and consequently can support individuals in becoming active participants, rather than passive recipients, in their own care process. In spite of numerous benefits suggested for consumers' utilizing PHR systems, research has shown that such systems are not yet widely adopted or well known to consumers. Bearing in mind the potential benefits of PHRs to consumers and their potential interest in these systems-and that similar to any other type of information system, adoption is a prerequisite for realizing the potential benefits of PHR systems-research is needed to understand how to enhance the adoption rates for PHR systems...

Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties. The underlying mechanisms of 2n gamete formation were recently revealed for Citrus reticulata but remain poorly understood for other citrus species, including lemon (C. limon [L.] Burm. f.). Here, we investigated the frequency and causal meiotic mechanisms of 2n megagametophyte production in lemon. We genotyped 48progeny plants of two lemon genotypes, "Eureka Frost" and "Fino", using 16 Simple Sequence Repeat (SSR) and 18 Single Nucleotide Polymorphism (SNP) markers to determine the genetic origin of the progenies and the underlying mechanisms for 2n gamete formation...

BACKGROUND: A Personal Health Record (PHR) is an online application that allows patients to access, manage, and share their health data. PHRs not only enhance shared decision making with healthcare providers, but also enable remote monitoring and at-home-collection of detailed data. The benefits of PHRs can be maximized in insulin dose adjustment for patients starting or intensifying insulin regimens, as frequent self-monitoring of glucose, self-adjustment of insulin dose, and precise at-home data collection during the visit-to-visit period are important for glycemic control...

HPV types with high viral load are associated with cervical abnormalities. However, viral load measurements and concordance of HPV loads and viral mRNA have not been demonstrated for all high-risk/possibly high-risk (HR-/pHR-)HPV types in cervical cancer (CxCa). Especially, the biological role of co-infecting HR-/pHR-HPV types with low viral load has not been thoroughly investigated. Using BSGP5+/6+-PCR/MPG genotyping, we analyzed viral loads for all currently defined 51 mucosal HPV types in 74 cervical smears from patients with CxCa and compared this data with HPV DNA and mRNA status in these patients' corresponding CxCa tissues...

The adoption of the Internet of Things (IoT) and mobile applications in the healthcare may transform the healthcare industry by offering better disease tracking and management as well as patient empowerment. Unfortunately, almost all of these new systems set up their own ecosystem and to be really valuable for the care process they need to be integrated or federated with user managed access control services based on international standards and profiles to enable interoperability. Thus, this work presents the results of an evaluation of available specifications for federated authorization, based on a set of basic requirements...

BACKGROUND: Choosing between total hip replacement (THR) and partial hip replacement (PHR) for patients with intracapsular hip fractures is often based on subjective factors. Predicting the survival of these patients and risk of surgical re-intervention is essential to select the most adequate implant. METHODS: We conducted a retrospective cohort study on mortality of patients over 70 years with intracapsular hip fractures who were treated between January 2010 and December 2013, with either PHR or THR...

The advances in the Information and Communications Technology (ICT) brought many benefits to the healthcare area, specially to digital storage of patients' health records. However, it is still a challenge to have a unified viewpoint of patients' health history, because typically health data is scattered among different health organizations. Furthermore, there are several standards for these records, some of them open and others proprietary. Usually health records are stored in databases within health organizations and rarely have external access...

Plant cryptochromes are photoreceptors that regulate flowering, circadian rhythm and photomorphogenesis in response to blue and UV-A light. It has been demonstrated that the oxidized flavin cofactor is photoreduced to the neutral radical state via separate electron and proton transfer. Conformational changes have been found in the C-terminal extension, but few studies have addressed the changes in secondary structure in the sensory photolyase homology region (PHR). Here, we investigated the PHR of the plant cryptochrome from the green alga Chlamydomonas reinhardtii by light-induced infrared difference spectroscopy in combination with global (13) C and (15) N isotope labeling...
