While dementia policy strategies emphasize the importance of partnerships between families and formal carers to provide tailored care and effectively allocate community resources, family carers often feel left out or excluded. Poor communication has been identified as one reason for the lack of good partnerships. Few studies have investigated how family carers seek to involve themselves when they experience sub-optimal services, and how their strategies may depend on different considerations and personal abilities.
 
  Qualitative in-depth interviews were conducted with 23 family carers to explore their experiences with, perspectives on, contributions to, and interactions with healthcare services provided to older adults living with dementia. To capture nuances and variations, a semi-structured interview guide was used. Interviews were audio-recorded and transcribed verbatim. A four-step analysis of the transcripts was conducted, informed by hermeneutic and phenomenological methodology.
 
  Two main involvementmaintain good partnerships together with family carers. A better understanding of family carers' own perspectives on carer involvement is a necessary precursor to developing good care partnerships.
  Evidence is scarce on the trend in prevalence of physical frailty in China; the primary purpose of this study was to identify the prevalence and correlates of physical frailty among older nursing home residents in China.
 
  Cross-sectional study in 20 nursing homes in Changsha, China. Physical frailty was defined based on the frailty phenotype including weight loss, low grip strength, exhaustion, slow gait speed, and low physical activity. Participants with at least three affected criteria were defined as being frail. Participants with one or two affected criteria were considered as pre-frail, and those with no affected criteria were considered as robust. A total of 1004 nursing home residents aged 60 and over were included in this study. A multinomial logistic regression model was used to analyze the associations of physical frailty with its potential risk factors, including age, sex, education levels, marital status, type of institution, living status, current drinking, current smoking, regular exercise, aailty warrant further investigations to explore their clinical application among elderly nursing home residents.
  Microbe-mediated redox transformation of arsenic (As) leading to its mobilization has become a serious environmental concern in various subsurface ecosystems especially within the alluvial aquifers. However, detailed taxonomic and eco-physiological attributes of indigenous bacteria from As impacted aquifer of Brahmaputra river basin has remained under-studied.
 
  A newly isolated As-resistant and -transforming facultative anaerobic bacterium IIIJ3-1 from As-contaminated groundwater of Jorhat, Assam was characterized. Near complete 16S rRNA gene sequence affiliated the strain IIIJ3-1 to the genus Bacillus and phylogenetically placed within members of B. cereus sensu lato group with B. cereus ATCC 14579(T) as its closest relative with a low DNA-DNA relatedness (49.9%). Presence of iC170, iC150 fatty acids and menaquinone 7 corroborated its affiliation with B. cereus group, but differential hydroxy-fatty acids, C182 and menaquinones 5 & 6 marked its distinctiveness.

The strain's ability to resist and transform As along with its capability to sequester As within the cells demonstrate its potential in designing bioremediation strategies for As contaminated groundwater and other ecosystems.
 This is the first report on molecular, taxonomic, and ecophysiological characterization of a highly As resistant, As3+ oxidizing, and dissimilatory As5+ reducing Bacillus sp. IIIJ3-1 from As contaminated sites of Brahmaputra river basin. The strain's ability to resist and transform As along with its capability to sequester As within the cells demonstrate its potential in designing bioremediation strategies for As contaminated groundwater and other ecosystems.
  At present, the distinctness, uniformity, and stability (DUS) testing of flue-cured tobacco (Nicotiana tabacum L.) depends on field morphological identification, which is problematic in that it is laborintensive, time-consuming, and susceptible to environmental impacts. In order to improve the efficiency and accuracy of tobacco DUS testing, the development of a molecular marker-based method for genetic diversity identification is urgently needed.
 
  In total, 91 simple sequence repeats (SSR) markers with clear and polymorphic amplification bands were obtained with polymorphism information content, Nei index, and Shannon information index values of 0.3603, 0.4040, and 0.7228, respectively. Clustering analysis showed that the 33 study varieties, which are standard varieties for flue-cured tobacco DUS testing, could all be distinguished from one another. Further analysis showed that a minimum of 25 markers were required to identify the genetic diversity of these varieties. Following the principle of two markersties.
  Gut microbial communities can contribute positively and negatively to host health. So far, eight core bacterial taxonomic clusters have been reported in honey bees.  https://www.selleckchem.com/products/vardenafil.html  These bacteria are involved in host metabolism and defenses. Nosema ceranae is a gut intracellular parasite of honey bees which destroys epithelial cells and gut tissue integrity. Studies have shown protective impacts of honey bee gut microbiota towards N. ceranae infection. However, the impacts of N. ceranae on the relative abundance of honey bee gut microbiota remains unclear, and has been confounded during prior infection assays which resulted in the co-inoculation of bacteria during Nosema challenges. We used a novel method, the suppression of N. ceranae with specific siRNAs, to measure the impacts of Nosema on the gut microbiome.
 
  Suppressing N. ceranae led to significant positive effects on microbial abundance. Nevertheless, 15 bacterial taxa, including three core taxa, were negatively correlated with N. ceranae levels. In particular, one co-regulated group of 7 bacteria was significantly negatively correlated with N.
