A Missing Piece of RSS Technology
In the Information Age, people use RSS (Really Simple Syndication) Technology to help them to easily get the latest contents from websites by accessing only a single website as well as by using mobile devices. Several companies have started to use RSS for distributing their information to customers. However, most contents published via RSS technology are public and not confidential such as credit card information, financial business information etc. Since the RSS technology does not have a mechanism to ensure that the incoming information is really secure, in this paper we have proposed a Secure Information Notifying System with RSS Technology (SInfoNS). We have applied the RSS technology together with the cryptography to make any RSS document become secure before disseminating it to relevant users. The SInfoNS also uses XSL to apply to private information retrieval and XML schema and SchemaPath definitions have been created for validation. The results displayed on a user's mobile device provide users with the latest information. The results of this study confirm that our system will aggregate RSS documents and disseminate information to each user. The SInfoNS enables RSS technology for the use of private information that can be securely distributed.Cryptography, Really Simple Syndication, RSS, XML Schema, XSL
Bacterial vaginosis biofilms: challenges to current therapies and emerging solutions
Bacterial vaginosis (BV) is the most common genital tract infection in women during their reproductive years and it has been associated with serious health complications, such as preterm delivery and acquisition or transmission of several sexually transmitted agents. BV is characterized by a reduction of beneficial lactobacilli and a significant increase in number of anaerobic bacteria, including Gardnerella vaginalis, Atopobium vaginae, Mobiluncus spp., Bacteroides spp. and Prevotella spp.. Being polymicrobial in nature, BV etiology remains unclear. However, it is certain that BV involves the presence of a thick vaginal multi-species biofilm, where G. vaginalis is the predominant species. Similar to what happens in many other biofilm-related infections, standard antibiotics, like metronidazole, are unable to fully eradicate the vaginal biofilm, which can explain the high recurrence rates of BV. Furthermore, antibiotic therapy can also cause a negative impact on the healthy vaginal microflora. These issues sparked the interest in developing alternative therapeutic strategies. This review provides a quick synopsis of the currently approved and available antibiotics for BV treatment while presenting an overview of novel strategies that are being explored for the treatment of this disorder, with special focus on natural compounds that are able to overcome biofilm-associated antibiotic resistance.Research on BV biofilms in NC laboratory is supported by

Impact of high fat diets, prebiotics and probiotics on gut microbiota and immune function, with relevance to elderly populations
According to WHO, the number of people over 60 years of age is set to rise to 2 billion by 2050. Dysbiosis of microbial composition and impaired immune function have been observed in elderly persons compared to younger adults. As a result, the aging population has a higher disease risk than other age groups. In addition, high fat intakes have been observed to exert negative effects on microbial composition and immune function in murine studies. Elderly people have higher fat intakes than recommended levels, and this may make them more vulnerable to disease risk. Therefore, the impact of high fat consumption on elderly populations may be of relevance. Prebiotics and probiotics have been shown to have positive effects on microbiota composition and immune function in the elderly. This review describes aged-related changes in gut microbiome of elderly persons. It will also summarise studies concerning the impact of prebiotics, probiotics and high fat diets on microbiota composition and immune function

The Impact of Photography on Tourism: Photography Construction Perspective
Photographs are crucial elements that marketers integrate into all their marketing communication tools. As we can see from many brochures, websites, and billboards, many travel destinations portray the beauty of their locations through photographs aiming to attract more travelers to visit their destinations. In the same vein, tourists also use photographs as references for their decisions about where to spend their vacations. Due to this significant impact of photographs on tourism, marketers invest greatly in this visual stimulation tool. However, the impact of elements appearing in each photograph such as objects and color tones are overlooked. This experimental study investigates the effects of cool and warm color tones in a photograph taken from the same beach scene in a tourism context.
The results of the study reveal that although cool color tones are expected to generate only relaxation, in a beach photograph, cool color tones are able to trigger excitement as well as warm color tones do. It might be assumed that warm color tone photographs taken during sunset time are able to promote relaxation. In fact, cool color tones photographs trigger significantly more relaxation. The effects of cool and warm color tones in a beach photograph on perceived escapability were tested. The research model also reflects how excitement, relaxation, and perceived escapability lead to attitude toward the destination, the role of aesthetic evaluation and visual style of processing as moderators, and the relationship among affective responses, cognitive responses, attitude, and intention to visit a travel destination. This research also contributes to academic knowledge in the tourism context and thus fills a gap in previous literature
