The article considers the features of organizing highly efficient telephone communication using cloud-based PBXs.
 advantages solutions based on IP-telephony compared to classical automatic exchanges are treated. It is shown that use a virtual PBX as separate configuration dedicated server will provide flexible system settings.

INTRODUCTION The effect of a prolonged oral anti-inflammatory therapy on PSA values in patients with persistent abnormal PSA values after negative prostate biopsy (PBx) was evaluated. MATERIAL AND METHODS From September 2011 to September 2012, 70 patients (medi- an age 62 years), with persistent abnormal PSA values after negative extended PBx, were given an herbal extract with anti-inflammato...

The present study investigated the roles of pre-B cell leukemia transcription factor 3 (PBX3) in sepsis. Reverse transcription-quantitative polymerase chain reaction and western blot analysis indicated that overexpression of the PBX 3'‑untranslated region (UTR) promoted high mobility group box 1 (HMGB1) protein expression in human umbilical vein endothelial cells (HUVECs) (P<0.01). Furthermore,...

HOX genes are vital for all aspects of mammalian growth and differentiation, and their dysregulated expression is related to ovarian carcinogenesis. The aim of the current study was to establish the prognostic value of HOX dysregulation as well as its role in platinum resistance. The potential to target HOX proteins through the HOX/PBX interaction was also explored in the context of platinum re...

A critical event in the adaptation to extrauterine life is relaxation of the pulmonary vasculature at birth, allowing for a rapid increase in pulmonary blood flow that is essential for efficient gas exchange. Failure of this transition leads to pulmonary hypertension (PH), a major cause of newborn mortality associated with preterm birth, infection, hypoxia, and malformations including congenita...

Hoxa1 belongs to the Hox family of homeodomain transcription factors involved in patterning embryonic territories and governing organogenetic processes. In addition to its developmental functions, Hoxa1 has been shown to be an oncogene and to be overexpressed in the mammary gland in response to a deregulation of the autocrine growth hormone. It has therefore been suggested that Hoxa1 plays a pi...

Hindbrain patterning requires many factors involved in early segmentation and later segment identity of the specific domains of the hindbrain. Hox proteins and their cofactors are of great importance durng segmentation of the hindbrain, because segmentation and/or segment identity are lost when any of them are lost. Previously, we have reported that Meis proteins synergize with Pbx, another Hox...

The cryptococcal capsule is a critical virulence factor of an important pathogen, but little is known about how it is associated with the cell or released into the environment. Two mutants lacking PBX1 and PBX2 were found to shed reduced amounts of the capsule polysaccharide glucuronoxylomannan (GXM). Nuclear magnetic resonance, composition, and physical analyses showed that the shed material w...

We predict a new class of large band gap quantum spin Hall insulators, the fluorinated PbX (X = C, Si, Ge and Sn) compounds, that are mechanically stable two-dimensional materials. Based on first principles calculations we find that, while the PbX systems are not topological insulators, all fluorinated PbX (PbXF2) compounds are 2D topological insulators. The quantum spin Hall insulating phase w...

During early development, the heart tube grows by progressive addition of progenitor cells to the arterial and venous poles. These cardiac progenitor cells, originally identified in 2001, are located in the splanchnic mesoderm in a region termed the second heart field (SHF). Since its discovery, our view of heart development has been refined and it is well established that perturbation in the a...
