Protocol for testosterone EIA, based on the protocol with the kit from Assay Design
Protocol for steroid radioimmunoassay of plasma
This protocol can be used to measure the concentration of steroid hormones in small plasma samples. This protocol has been copied and modified from protocols provided by Dr. John Wingfield at the University of Washington. It has been written for use in the laboratory of Dr. Ellen Ketterson at Indiana University, and therefore the details may require modification if the procedure is performed elsewhere. The general procedure, which takes 4-5 days to complete, is described below. Prepared January 1998 by Joe Casto, modified December 2005 by Jodie Jawor and May 2010 by Danielle Whittaker
Anxiety, history of childhood adversity, and experiencing chronic pain in adulthood: A systematic literature review and meta-analysis
Background: When considering factors that may impact chronic pain experiences in adulthood, adverse childhood experiences (ACEs) and anxiety should be considered. The literature on the associations between these 3 variables remains unclear. Objective: To summarize the existing literature on the relationship between ACEs and anxiety on chronic pain experience in adults, and examine the association between ACEs and anxiety. Methods: A systematic literature review (SLR) and meta-analysis was used to examine adults (≥18) with a reported history of ACEs, self-reported and/or diagnosed anxiety, and chronic pain. The SLR included quality appraisal according to the Joanna Briggs Institute tool. Results: The narrative summary indicated a significant association between ACEs, anxiety, and chronic pain experiences in adults. Of 52 selected studies, 79% reported a moderate-strong association. For ACE prevalence, the majority reported experiencing sexual abuse (50% [SD 16.01]), followed by physical abuse (46% [SD 20.7]). Other ACEs included emotional abuse (33% [SD 17.17]), emotional neglect (25% [SD 21.02]), and physical neglect (23% [SD 22.44]). Meta-analyses showed moderate associations between anxiety and chronic pain (r = 0.30; 95% CI = [0.14, 0.45], p < 0.01) and between ACEs and anxiety (r = 0.26; 95% CI = [0.15, 0.36], p < 0.01), and that participants who experienced ACEs are around twice as likely to present chronic pain during adulthood (OR = 1.99; 95% CI = [1.53, 2.60], p < 0.01). Conclusion: The results of the SLR and meta-analysis indicated that ACEs and anxiety influence chronic pain experience in adults. Given the relationship between ACEs and anxiety, there would be value in exploring this as a potential mediator in future studies. Significance: There was an unmet need to summarize the existing literature on the relationship between ACEs and anxiety on chronic pain experience in adults and the association between ACEs and anxiety. The results of this systematic review and meta-analysis indicated that both ACEs and anxiety influenced chronic pain experience in adults and helped to inform the diverse literature on these potential relationships to date
An analysis on history of childhood adversity, anxiety, and chronic pain in adulthood and the influence of inflammatory biomarker C-reactive protein
Despite a link between adverse childhood experiences (ACEs) and anxiety, the role of anxiety in the pathway to chronic pain is unclear. Potentially, inflammatory biomarkers such as C-reactive protein (CRP) are involved. Objectives were to (1) examine relationships between reported ACEs, anxiety, and chronic pain, and (2) assess associations between ACEs, anxiety, and CRP levels and between CRP and chronic pain. Data from 24,172 adults who participated in the UK Biobank were used to conduct Poisson regressions to assess relationships between ACEs, anxiety, and chronic pain. For participants with CRP data who met the inclusion criteria (n = 2007), similar models were run between ACEs, anxiety, and CRP, and CRP and chronic pain. For objective 1, three statistically significant interactions were found to predict pain: frequency of physical abuse x reported muscular symptoms during anxiety (p = 0.01); frequency in which they felt hated x having discussed anxiety with a professional (p = 0.03), and reported frequency of sexual abuse x difficulties relaxing during anxiety attacks (p = 0.03). For objective 2, frequency of sexual abuse and informing a professional about anxiety significantly interacted to predict elevated CRP. For correlations, the largest was between CRP and the number of times pain was reported over the years (p = 0.01). Finally, ACEs (physical abuse, sexual abuse, and whether taken to a doctor) significantly interacted with CRP to predict pain. This study suggests mechanisms of the impact of ACEs on chronic pain may include inflammation and anxiety, which warrants further study
Extension’s use of Zoom to Address a Public Health Risk Among Older Adults
Mandates that require social distancing and sheltering-in-place to stop the spread of the coronavirus have worsened an already concerning public health issue for older adults –social isolation and loneliness. Alabama Extension System at Alabama A&M University developed a program focused on helping older adults connect with family and friends. A descriptive study of 37 older adults indicated that their knowledge, ability, and comfort with implementing Zoom sessions increased significantly after completing the program. Findings show the potential use of the Zoom for Seniors program in preventing social isolation or loneliness among older adults

Spider monkeys rule the roost: Ateline sleeping sites influence rainforest heterogeneity
: The sleeping site behavior of Ateline primates has been of interest since the 1980s, yet limited focus has been given to their influence upon other rainforest species. Here, we use a combination of arboreal and terrestrial camera traps, and dung beetle pitfall traps, to characterize spider monkey sleeping site use and quantify the impact of their associated latrines on terrestrial vertebrate and dung beetle activity. We also characterize the physical characteristics of the sleeping sites and the floristic and soil composition of latrines beneath them. Spider monkey activity at sleeping sites peaked at dawn and dusk and group composition varied by sex of the adults detected. The habitat-use of terrestrial fauna (vertebrates and dung beetles) differed between latrine sites and non-latrine controls, underpinned by species-specific changes in the relative abundance of several seed-dispersing species (such as paca and great curassow). Seedling density was higher in latrines than in non-latrine controls. Although most soil properties were similar between latrines and controls, potassium and manganese concentrations were different. These results suggest that spider monkey sleeping site fidelity leads to a hotspot of ecological activity in latrines and downstream impacts on rainforest floristic composition and diversity
Mid-Late Quaternary Fluvial Archives near the Margin of the MIS 12 Glaciation in Southern East Anglia, UK: Amalgamation of Multi-Disciplinary and Citizen-Science Data Sources
This paper presents an updated geological reconstruction of the Quaternary evolution of the River Thames at its downstream extremities, close to the North Sea coast, based on new data from multi-disciplinary and citizen-science sources. In this area, the interaction of the Thames with the MIS 12 (Anglian) glaciation is an important part of the Quaternary archive. The Anglian ice sheet, which reached parts of north and east London, was responsible for diverting the Thames southwards into its present course, although the footprint of the maximum ice sheet(s) does not reach the North Sea coast south of Hollesley, Suffolk. Further south, the coastal zone hosts pre-Anglian and early Anglian river-terrace deposits of the pre-diversion Thames system, superimposed upon which are products of later post-Anglian rivers, of both Middle and Late Pleistocene age. On the peninsula between the Stour and Blackwater–Colne estuaries, the lowest and most recent terrace of the pre-diversion Thames includes evidence directly pertaining to the glacial disruption event, for which geochronological data are reported here for the first time. The first post-diversion terrace of the Thames also reaches this peninsula, the river having essentially re-joined its original valley before crossing the alignment of the modern coastline. This terrace passes beneath Clacton-on-Sea, where it includes the type locality of the Clactonian Palaeolithic Industry. The area of interest to this paper, in NE Essex and southern Suffolk, includes a number of interglacial and Palaeolithic sites, the data from which assist in constraining the chronostratigraphy of the sequence. In some cases, there has been uncertainty as to whether these sites represent pre-Anglian environments and hominin occupations, part of the palaeo-Thames sequence, or whether they are the product of later post-Anglian streams, formed after the Thames had migrated southwards. This paper compiles evidence from a wide range of recent sources, including developer-funded archaeological appraisal and citizen-science activities, to explore and update the evidence from sites at Ipswich, Upper Dovercourt and Thorpe-le-Soken, as well as a number of localities associated with the Clacton Channel Deposits (host to the type-Clactonian), amongst others. The resulting new data are placed within the wider context of the Quaternary fluvial archives in southern Britain, with a discussion of how disparate sources of information, including the work of citizen scientists, have contributed

De novo transcriptome sequencing in a songbird, the dark-eyed junco (Junco hyemalis):genomic tools for an ecological model system
BACKGROUND: Though genomic-level data are becoming widely available, many of the metazoan species sequenced are laboratory systems whose natural history is not well documented. In contrast, the wide array of species with very well-characterized natural history have, until recently, lacked genomics tools. It is now possible to address significant evolutionary genomics questions by applying high-throughput sequencing to discover the majority of genes for ecologically tractable species, and by subsequently developing microarray platforms from which to investigate gene regulatory networks that function in natural systems. We used GS-FLX Titanium Sequencing (Roche/454-Sequencing) of two normalized libraries of pooled RNA samples to characterize a transcriptome of the dark-eyed junco (Junco hyemalis), a North American sparrow that is a classically studied species in the fields of photoperiodism, speciation, and hormone-mediated behavior. RESULTS: From a broad pool of RNA sampled from tissues throughout the body of a male and a female junco, we sequenced a total of 434 million nucleotides from 1.17 million reads that were assembled de novo into 31,379 putative transcripts representing 22,765 gene sets covering 35.8 million nucleotides with 12-fold average depth of coverage. Annotation of roughly half of the putative genes was accomplished using sequence similarity, and expression was confirmed for the majority with a preliminary microarray analysis. Of 716 core bilaterian genes, 646 (90 %) were recovered within our characterized gene set. Gene Ontology, orthoDB orthology groups, and KEGG Pathway annotation provide further functional information about the sequences, and 25,781 potential SNPs were identified. CONCLUSIONS: The extensive sequence information returned by this effort adds to the growing store of genomic data on diverse species. The extent of coverage and annotation achieved and confirmation of expression, show that transcriptome sequencing provides useful information for ecological model systems that have historically lacked genomic tools. The junco-specific microarray developed here is allowing investigations of gene expression responses to environmental and hormonal manipulations – extending the historic work on natural history and hormone-mediated phenotypes in this system
