The default mode network (DMN) is a network of brain regions that is activated while we are not engaged in any particular task. While there is a large volume of research documenting functional connectivity within the DMN in adults, knowledge of the development of this network is still limited. There is some evidence for a gradual increase in the functional connections within the DMN during the first 2 years of life, in contrast to other functional resting-state networks that support primary sensorimotor functions, which are online from very early in life. Previous studies that investigated the development of the DMN acquired data from sleeping infants using fMRI. However, sleep stages are known to affect functional connectivity. In the current longitudinal study, fNIRS was used to measure spontaneous fluctuations in connectivity within fronto-temporoparietal areas-as a proxy for the DMN-in awake participants every 6 months from 11 months till 36 months. This study validates a method for recording resting-state data from awake infants, and presents a data analysis pipeline for the investigation of functional connections with infant fNIRS data, which will be beneficial for researchers in this field. A gradual development of fronto-temporoparietal connectivity was found, supporting the idea that the DMN develops over the first years of life. Functional connectivity reached its maximum peak at about 24 months, which is consistent with previous findings showing that, by 2 years of age, DMN connectivity is similar to that observed in adults. © 2020 The Authors.

NHANES data indicate that nearly all Americans have trace amounts of PBDEs in serum, with even higher levels associated with occupational exposure. PBDEs are known to bioaccumulate in the environment due to their lipophilicity and stability, and more importantly, they have been detected in human adipose tissue. The present study examined whether the PBDE congener, BDE-99 (2,2',4,4',5-pentabromodiphenyl ether; 0.2-20 μM), enhances the adipogenesis of mouse and human preadipocyte cell models in vitro via induced lipid accumulation. 3T3-L1 mouse preadipocytes and human visceral preadipocytes demonstrated enhanced hormone-induced lipid accumulation upon BDE-99 treatment. In addition, BDE-99 (20 μM) induced preadipocyte differentiation and lipid development in nondifferentiated human preadipocytes. BDE-99, the second most abundant congener in human adipose tissue, increased total lipids in differentiating adipocytes and therefore showed a potential role in the regulation of adipogenesis. This warrants more research to further understand the impact of lipophilic persistent pollutants on adipose tissue homeostasis. © 2020 Wiley Periodicals, Inc.OBJECTIVES The impact of religion/spirituality (R/S) on cancer outcomes, including health-related quality of life (HRQoL), has been the topic of much investigation. Reports of the opposite, i.e., the impact of cancer on R/S and associations with HRQoL, are few. The current study sought to explore the positive and negative impacts of cancer on the religious faith of survivors as well as the associations of such impacts with HRQoL. METHODS Participants included 2309 9-year survivors of cancer from the American Cancer Society's Studies of Cancer Survivors - I. The impact of cancer on R/S was measured using items from the PROMIS Psychosocial Impact of Illness - Faith, and HRQoL was measured with the SF-12. Hierarchical regressions were used to examine the impact of cancer on R/S controlling for medical and demographic covariates. RESULTS Consistent with hypotheses, the majority of survivors (70%) reported that cancer had a positive impact on religious faith, while the negative impact of cancer on religious faith was relatively rare (17%). In multivariable models, the negative impact of cancer on faith was associated with poorer HRQoL, both mental and physical, while the positive impact of cancer on faith was associated with greater mental well-being. CONCLUSIONS Cancer has a negative impact on religious faith for a minority of survivors. AT7519 However, when it is reported, such negative impact is indicative of poorer mental and physical well-being. As such, it is important to identify those survivors at risk early in survivorship and provide support and intervention as needed. This article is protected by copyright. All rights reserved.

Unfortunately, their consumption is increasingly associated with food-borne diseases, Salmonella enterica being their most frequent cause in Europe. Agricultural soils were postulated as reservoir of human pathogens, contributing to the contamination of crops during the growing period. Since the competition with the indigenous soil microbiota for colonization sites plays a major role in the success of invading species, we hypothesized that reduced diversity will enhance the chance of Salmonella to successfully establish in agricultural environments. We demonstrated that the abundance of Salmonella drastically decreased in soil with highly diverse indigenous prokaryotic community, while in soil with reduced prokaryotic diversity, Salmonella persisted for a long period. Furthermore, in communities with low diversity, Salmonella had an impact on the abundance of other taxa. The high physiological plasticity allows Salmonella to use agricultural soils as alternative habitat which might provide a route of animal/human infections. In addition, adjusted transcriptional profile with amino acid biosynthesis and the glyoxylate cycle most prominently regulated, suggests an adaptation to the soil environment. Our results underline the importance of the maintenance of diverse soil microbiome as a part of strategy aiming at reduced risk of food-borne salmonellosis outbreaks. © 2020 The Authors.
