All sweet-tasting compounds are detected by a single G-protein coupled receptor (GPCR), the heterodimer T1R2-T1R3, for which no experimental structure is available. The sweet taste receptor is a class C GPCR, and the recently published crystallographic structures of metabotropic glutamate receptor (mGluR) 1 and 5 provide a significant step forward for understanding structure-function relationships within this family. In this article, we recapitulate more than six hundred single point site-directed mutations and available structural data to obtain a critical alignment of the sweet taste receptor sequences with respect to other class C GPCRs...

REVIEW
Xiaohua Mao, Zhenyi Su, Adnan K Mookhtiar
The Nuclear Factor-κB (NF-κB) family of transcription factors play an essential role for the regulation of inflammatory responses, immune function and malignant transformation. Aberrant activity of this signaling pathway may lead to inflammation, autoimmune diseases and oncogenesis. Over the last two decades great progress has been made in the understanding of NF-κB activation and how the response is counteracted for maintaining tissue homeostasis. Therapeutic targeting of this pathway has largely remained ineffective due to the widespread role of this vital pathway and the lack of specificity of the therapies currently available...

The Nudix homology clan encompasses over 80,000 protein domains from all three domains of life, defined by homology to each other. Proteins with a domain from this clan fall into four general functional classes: pyrophosphohydrolases, isopentenyl diphosphate isomerases (IDIs), adenine/guanine mismatch-specific adenine glycosylases (A/G-specific adenine glycosylases), and non-enzymatic activities such as protein/protein interaction and transcriptional regulation. The largest group, pyrophosphohydrolases, encompasses more than 100 distinct hydrolase specificities...

REVIEW
Nikos Vasilakis, Scott C Weaver
Flaviviruses are among the most diverse viruses with over 85 species recognized. Taxonomically, this genus is one of the 4 recognized genera within the family Flaviviridae. Most flaviviruses of human public health significance, for example, dengue, yellow fever and Zika viruses, are arthropod-borne (arboviruses) and have two evolutionarily and ecologically distinct transmission cycles: a sylvatic transmission cycle, where the virus circulates between zoonotic vertebrate reservoir and amplification hosts and arboreal mosquitoes; and an urban transmission cycle, where the virus circulates between humans and peridomestic Aedes spp...

With population aging now a global phenomenon, the health of older adults is becoming an increasingly important issue. Because the Korean population is aging at an unprecedented rate, preparing for public health problems associated with old age is particularly salient in this country. As the physical and mental health of older adults is related to their social relationships, investigating the social networks of older adults and their relationship to health status is important for establishing public health policies...

Yu Li, Li-Min Wang, Jian-Zhong Xu, Ke Tian, Chen-Xi Gu, Zhi-Fu Li
Gastrodia elata (GE), which belongs to the Orchidaceae family, was found to possess anti-inflammatory activity. However, the effect of GE on inflammatory response in rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) remains largely unknown. Thus, the aim of this study was to investigate the effects of GE on tumor necrosis factor-α (TNF-α)-induced inflammatory response in RA-FLS and the underlying molecular mechanism was also explored. Our results demonstrated that GE significantly attenuated TNF-α-induced IL-6 and IL-8 production in RA-FLS...

BACKGROUND: As the survival rate of preterm infants constantly improves, knowledge on the impact of prematurity on long-term health-related quality of life (HRQoL) is important for clinical and parental guidance. We aimed to assess HRQoL in a national cohort of young adolescents born very preterm, and to identify predictors for poorer HRQoL. PATIENTS AND METHODS: All surviving Swiss live-born children below 30weeks of gestation during the year 2000 (290 subjects) were contacted at age 12years, together with their parents (262 families)...

Weissella are obligate heterofermentative lactic acid bacteria belonging to the Leuconostocaceae family. Some Weissella can be found in salted and fermented foods, such as kimchi and jeotgal, and plays an important role in the fermentation process. In the present study, for the first time, a rapid and accurate identification method for Weissella species from kimchi and jeotgal was developed based on MALDI-TOF MS, supplemented with an in-house database. Of the 135 Weissella spectra aligned with the MALDI bioTyper database, 56 isolates (41...

OBJECTIVE: Alcohol-related car crashes are a leading cause of adolescent death, and one in five U.S. adolescents reports recent riding in a car with a drinking driver. How often the driver is an adult in the home (e.g., parent) is unknown. Pediatric visits offer an opportunity to counsel families to reduce this risk. Our study aim was to determine the prevalence of recent riding with a drinking driver (RWDD) who was an adult in the home among adolescent primary care patients and to identify the demographic and environmental (substance use among family members) profiles of those at increased risk...

The pertinence of a therapeutic programme of education has been studied with regard to carers of patients suffering from major neurocognitive disorders. The programme, adapted to the needs expressed by the carers, consisted of three workshops with a view to supplying general information about the pathologies, specific information on behavioural disorders and specific aids to identify and manage their emotional reactions. The results of this preliminary study show a moderate significant benefit to the level of anxiety in the participants, taking into account the specific expectations of the carers and bringing to light further needs...

Excessive gaming among emerging adults is a growing concern, especially in cases where it interferes with key developmental milestones such as gaining an education or establishing a career. Although researchers have begun to understand the effects of excessive gaming on young people themselves, we know remarkably little about how emerging adults' gaming may affect family relationships. Utilizing phenomenological interviewing of parents of emerging adult sons who game excessively, this study presents a rich description of the experience of parenting a young adult who games excessively...

To support personal recovery, any person with a mental illness should have access to a range of practices recommended by scientific evidence. The peer support are some of the services recommended by the Mental Health Commission of Canada for the reduction of the economic and social burden of mental illness. If peer support from families is poorly documented, peer support and mutual aid from users have been the subject of several studies. Based on two studies in which she participated, addressing the needs of families, and its experience as a non-profit support organization for families, the Quebec Society of Schizophrenia (QSS) has reflected on the family support problem upon entry in the health system as well as the involvement of families as peer support...

Many research, notably that of Gene Cohen (2007), have shown positive impact of artistic activities for seniors. In 2006 in Quebec City, three professional painters have created a none lucrative organization called Les Pinceaux d'Or (The Golden Brushes). Its mission is to create a positive experience of painting learning in elderly needing persons. The organization operates in long-term health-care facilities or in low-income housings and day centers. It offers free painting courses to elderly persons referred by local community health centers or community organizations as seniors with psychosocial needs...

This paper presents an exploratory reflection on the question of individual experience by patients in psychiatric institutions, in its historical dimension. Are such experiences comprehensible through an analysis of the archives originating in the hospital? This reflection forms part of a study concerning the circumstances in which women were placed in psychiatric institutions, in Belgium during interwar period (1918-1940); its ultimate objective is to come to an understanding of the social, individual and familial situations that lead to a decision to intern a woman in a closed psychiatric institution...

To help learn how phytopathogens feed from their hosts, genes for nutrient transporters from the hemibiotrophic potato and tomato pest Phytophthora infestans were annotated. This identified 453 genes from 19 families. Comparisons with a necrotrophic oomycete, Pythium ultimum, and a hemibiotrophic fungus, Magnaporthe oryzae, revealed diversity in the size of some families although a similar fraction of genes encoded transporters. RNA-seq of infected potato tubers, tomato leaves, and several artificial media revealed that 56 and 207 transporters from P...

The Strait of Sicily was recognized internationally as an "Ecologically or Biologically Significant Area" by the Contracting Parties of the Convention on Biological Diversity in 2014. However, basic aspects of its fish diversity are still unknown and most of the information comes from traditional trawl surveys. This paper provides the first detailed description, using a Remotely Operated Vehicle (ROV), of the composition and depth distribution of the demersal fish assemblages found on banks of the Strait of Sicily and the related habitat complexity from 35 to 240 m depth...

PURPOSE: Resilience is the individual's ability to bounce back from trauma. It has been studied for some time in the U.S., but few studies in China have addressed this important construct. In mainland China, relatively little is known about the resilience of patients in clinical settings, especially among patients with breast cancer. In this study, we aimed to evaluate the level of resilience and identify predictors of resilience among mainland Chinese women newly diagnosed with breast cancer...

Phosphatase and tensin homolog (PTEN) is a tumor-suppressor gene. PTEN pseudogene (PTENp) acts as an endogenous RNA, which regulates its parental gene by competitively binding to the 3' UTR of PTEN gene in the human. Despite the importance of this pseudogene, little is known about the molecular evolution of PTENp in mammals. In this study, we identified 37 pseudogenes from 65 mammalian genomes. Among them, 32 were from rodents or primates. Phylogenetic analyse showed a complex evolutionary history of this gene family...
