Heat shock proteins (Hsps) co-operate in multi-protein machines that counter protein misfolding and aggregation and involve DNAJ (Hsp40), HSPA (Hsp70), and HSPH (Hsp105α). The HSPA family is a multigene family composed of inducible and constitutively expressed members. Inducible HSPA6 (Hsp70B') is found in the human genome but not in the genomes of mouse and rat. To advance knowledge of this li...

The human gastric pathogen Helicobacter pylori (H. pylori) is a successful colonizer of the stomach. H. pylori infection strongly correlates with the development and progression of chronic gastritis, peptic ulcer disease, and gastric malignances. Vaccination is a promising strategy for preventing H. pylori infection. In this study, we evaluated the candidate antigens heat shock protein A (HspA)...

New applications put out by the service providers require high data rates in order to enjoy the best performance of its functionalities, hence to have a good Quality of Service (QoS). To provide the system with a solution to enable a good service to user equipments one can adopt the HCS (Hierarchical Cell Structure) model. The model is considered to improve the system’s capacity, coverage and q...

We investigated whether Helicobacter pylori cells actively secrete proteins such as the urease subunits UreA and UreB and the GroES and GroEL homologs HspA and HspB or whether these proteins were present in the extracellular compartment as a consequence of autolysis. Using a subcellular fractionation approach associated with quantitative Western blot analyses, we showed that the supernatant pro...

In this paper, a field test platform called OTTCAP (OTT Services Capture and Analyze Platform) is developed for capturing and analyzing QoS (Quality of Service) and QoE (Quality of Experience) parameters of OTT (over-the-top) services in HSPA+ (Evolved High Speed Packet Access) networks, including Network-Level and Application-Level QoS parameters, terminal parameters and wireless environment p...

ارتقای بازدارندگی دفاعی مستلزم تولید گسترده و متنوع محصولات تجهیزات نظامی است که نیازمند به‌کارگیری ظرفیت‌ها قابلیت‌های وسیع صنعتی است. ازآنجاکه تصدی تملک همه این قابلیت‌ها منطقی اقتصادی نیست، بخشی از فعالیت‌های تولیدی در صنایع دفاعی، برون‌سپاری می­‌شود به ایجاد شبکه بزرگی تأمین‌کنندگان منجر شده گستردگی شبکه، تعاملات همکارانه بهبود عملکرد زنجیره تأمین را یک چالش جدی برای مدیران تبدیل کرده سازما...

When a shared channel or packet switched network is used for transmission (e.g. WLAN, HSPA (Turbo-3G), LTE (4G)), it introduces variance in the delay of packets. This variance is called jitter. This jitter can lead to significant degradation of quality in real-time services if it is not properly handled. High Speed Packet Access (HSPA) is an extension to the third Generation W-CDMA cellular net...

To look for evidence of intrafamilial infection, we isolated 107 Helicobacter pylori clones from biopsied specimens taken from both parents and four children. We compared the sequences of two housekeeping genes (hspA and glmM) from these clones with those of 131 unrelated strains from patients living in different geographic regions. Strain relationships within the family were determined by anal...

In this paper we give an overview of wireless mobiles, starting form first generation (1G) based on analogue system in 1980, while second generation (2G) which sets initial digital standards focuses on capacity and coverage. Emergence of GSM also belongs to 2G. After that third generation (3G) continues with the upgradation and adoption of new technologies such as UMTS-HSPA and CDMA200 EV-DO to...
