Gender Differences In Space-Use Patterns And Microhabitat Characteristics Of Southern Flying Squirrel (Glaucomys Volans) In Northeastern Iowa

Southern flying squirrel (Glaucomys volans) is common throughout the eastern deciduous forests of the United States, southern Canada, Mexico, and Central America. However, within the state of Iowa G. volans currently is listed as a “species of special concern.” This status is due to general loss of local habitat and lack of information about the species within the state. The state of Iowa has lost a majority of its native land cover over the past century due to intensive agricultural practices. Most native forests have been reduced drastically. The majority of habitat that would be suitable for southern flying squirrel has been fragmented or destroyed. These combined factors have led to the current listing of southern flying squirrel as a species of special concern within the state of Iowa. I studied southern flying squirrel at two sites in northeastern Iowa; the Mines of Spain State Recreational Area (MoSRA) and Wolter Property. The majority of my research was done at MoSRA. These sites were located in Dubuque and Clayton counties. Beginning in the summer of 2012 and continuing in the summers of 2014 and 2015 male and female southern flying squirrel were fitted with radio transmitters. Both male and female southern flying squirrels were tracked subsequently by using radio telemetry techniques. During the course of this research 11 males and 15 females were fitted with radio transmitters. Tracking results were variable; while some individuals (1 male and 3 females) yielded only a few locations, others were successfully tracked for up to two months. Home range area varied from 2.4 ha to 71.1 ha. Home ranges were larger for males than for females (P-value = 0.048). Males showed more variation in their range size as well. This variation possibly is due to the high degree of fragmentation within this habitat. Comparisons between my study home range sizes in other portions of southern flying squirrel range showed significant differences. Studies where southern flying squirrel home ranges were measured in contiguous forest habitat were smaller than those measured in my study. Home ranges of southern flying were used to determine microhabitat selection. After determining home range boundaries habitat was sampled both habitat within home ranges (Used) and outside of home ranges (Available). These points were selected by using stratified random sampling design. These data were then used to determine if there is specific microhabitat selection by this species and if so what habitat variables they respond to most strongly. Habitat variables that were significant for explaining the presence of southern flying squirrel were distance-to-nearest-neighbor (distance between trees), tree height, litter depth, and forb cover. Tree species were not significant in explaining presence of southern flying squirrel. Forest structure, not forest community, appeared to be more critical in predicting the habitat of southern flying squirrel. These data hopefully will yield a better understanding of space-use and ecology at a landscape level for the southern flying squirrel in northeastern Iowa. Currently, it is not understood how southern flying squirrel respond to forest characteristics in northeastern Iowa. Understanding movement patterns and habitat associations becomes vital should this species be listed as threatened or endangered within the state of Iowa

Why do seniors leave resistance training programs?

Purpose: The proportion of the population, that is older, is growing at a faster rate than other age groups. Physical activity is important for older people because it assists in living independently. Participating in resistance training on a regular basis (twice weekly) is recommended for older people; yet, fewer than 15% of people over 60 years achieve this level. The aim of this article was to investigate the factors contributing to older people’s decisions to stop participation in a resistance training program. Participants and methods: Participants were older people who had chosen to participate in a structured resistance training program specifically designed for seniors and then after a period of time discontinued. This population received a questionnaire in the mail focused on factors contributing to their cessation of resistance training exercise. Qualitative results were analyzed using inductive content analysis. Results: Fifty-six survey responses were received (average age 71.5 years, SD =9.0; 79% females). Injury, illness, and holidaying were the main reasons for ceasing participation. A small but important number of responses (11%) reported that they considered they were not provided with sufficient support during the resistance training programs. Conclusions: To attract and retain their senior clients, the results indicate that program organizers need to provide tailored support to return to resistance training after injury and offer flexible and individualized services that accommodate older people’s life choices in retirement

When learning becomes a fetish: the pledge, turn and prestige of magic tricks

It is our contention that the process of higher education could be read as a commodity and in both Marxian and Freudian assumptions, a fetish. Instrumental in this discussion are; Marx’s theorising of the commodity fetish (1867) that deceives by conflating the distinction between use and exchange value, and Freud’s (1927) re-visiting of his theory of fetishism, where he considers the fetish in the context of dealing with separation and loss in everyday life. This paper highlights how the consequence of fetishised behaviour has led to violent outcomes, such as the policy decision to introduce a ‘Teaching Excellence Framework’ (TEF). We argue that the TEF may bring about the death of learning in HE and diminish the role of academic staff. Nevertheless, influenced by Winnicott, Cixous and Biesta, we offer a more hopeful ‘Teaching that is Good Enough Framework’

Bridging Alone: Religious Conservatism, Marital Homogamy, and Voluntary Association Membership

This study characterizes social insularity of religiously conservative American married couples by examining patterns of voluntary associationmembership. Constructing a dataset of 3938 marital dyads from the second wave of the National Survey of Families and Households, the author investigates whether conservative religious homogamy encourages membership in religious voluntary groups and discourages membership in secular voluntary groups. Results indicate that couples’ shared affiliation with conservative denominations, paired with beliefs in biblical authority and inerrancy, increases the likelihood of religious group membership for husbands and wives and reduces the likelihood of secular group membership for wives, but not for husbands. The social insularity of conservative religious groups appears to be reinforced by homogamy—particularly by wives who share faith with husbands

A signalome screening approach in the autoinflammatory disease TNF Receptor Associated Periodic Syndrome (TRAPS) highlights the anti-inflammatory properties of drugs for repurposing

TNF Receptor Associated Periodic Syndrome (TRAPS) is an autoinflammatory disease caused by mutations in TNF Receptor 1 (TNFR1). Current therapies for TRAPS are limited and do not target the pro-inflammatory signalling pathways that are central to the disease mechanism. Our aim was to identify drugs for repurposing as anti-inflammatories based on their ability to down-regulate molecules associated with inflammatory signalling pathways that are activated in TRAPS. This was achieved using rigorously optimised, high through- put cell culture and reverse phase protein microarray systems to screen compounds for their effects on the TRAPS-associated inflammatory signalome. 1360 approved, publically available, pharmacologically active substances were investigated for their effects on 40 signalling molecules associated with pro-inflammatory signalling pathways that are constitutively upregulated in TRAPS. The drugs were screened at four ten-fold concentrations on cell lines expressing both wild-type (WT) TNFR1 and TRAPS-associated C33Y mutant TNFR1, or WT TNFR1 alone; signalling molecule levels were then determined in cell lysates by the reverse phase protein microarray. A novel mathematical methodology was developed to rank the compounds for their ability to reduce the expression of signalling molecules in the C33Y-TNFR1 transfectants towards the level seen in the WT-TNFR1 transfectants. Seven high-ranking drugs were selected and tested by RPPA for effects on the same 40 signalling molecules in lysates of peripheral blood mononuclear cells (PBMCs) from C33Y-TRAPS patients compared to PBMCs from normal controls. The fluoroquinolone antibiotic lomefloxacin, as well as others from this class of compounds, showed the most significant effects on multiple pro-inflammatory signalling pathways that are constitutively activated in TRAPS; lomefloxacin dose-dependently significantly reduced expression of 7/40 signalling molecules across the Jak/Stat, MAPK, NF-kB and PI3K/AKT pathways. This study demonstrates the power of signalome screening for identifying candidates for drug repurposing

Targeted Sequencing in Chromosome 17q Linkage Region Identifies Familial Glioma Candidates in the Gliogene Consortium

Glioma is a rare, but highly fatal, cancer that accounts for the majority of malignant primary brain tumors. Inherited predisposition to glioma has been consistently observed within non-syndromic families. Our previous studies, which involved non-parametric and parametric linkage analyses, both yielded significant linkage peaks on chromosome 17q. Here, we use data from next generation and Sanger sequencing to identify familial glioma candidate genes and variants on chromosome 17q for further investigation. We applied a filtering schema to narrow the original list of 4830 annotated variants down to 21 very rare (,0.1% frequency), non-synonymous variants. Our findings implicate the MYO19 and KIF18B genes and rare variants in SPAG9 and RUNDC1 as candidates worthy of further investigation. Burden testing and functional studies are planned

Making sense of policy choices: understanding the roles of value predispositions, mass media, and cognitive processing in public attitudes toward nanotechnology

Using a nationally representative telephone survey of 1,015 adults in the United States, this study examines how value predispositions, communication variables, and perceptions of risks and benefits are associated with public support for federal funding of nanotechnology. Our findings show that highly religious individuals were less supportive of funding of nanotech than less religious individuals, whereas individuals who held a high deference for scientific authority were more supportive of funding of the emerging technology than those low in deference. Mass media use and elaborative processing of scientific news were positively associated with public support for funding, whereas factual scientific knowledge had no significant association with policy choices. The findings suggest that thinking about and reflecting upon scientific news promote better understanding of the scientific world and may provide a more sophisticated cognitive structure for the public to form opinions about nanotech than factual scientific knowledge. Finally, heuristic cues including trust in scientists and perceived risks and benefits of nanotech were found to be associated with public support for nanotech funding. We conclude with policy implications that will be useful for policymakers and science communication practitioners

Dupuytren’s Interventions Surgery versus Collagenase (DISC) Trial : Study Protocol for a pragmatic, two arm parallel group, non-inferiority randomised controlled trial

Background: Dupuytren’s contracture is a fibro-proliferative disease of the hands affecting over 2 million UK adults, particularly the white, male population. Surgery is the traditional treatment, however recent studies have indicated that an alternative to surgery - Collagenase Clostridium Histolyticum (Collagenase) - is better than placebo in the treatment of Dupuytren’s contracture. There is however no robust randomised controlled trial that provides a definitive answer on the clinical effectiveness of Collagenase compared with limited fasciectomy surgery. The Dupuytren’s Interventions Surgery vs Collagenase Trial (DISC) Trial was therefore designed to fill this evidence gap. Methods/Design: The DISC Trial is a multi-centre pragmatic two arm parallel group, randomised controlled trial. Participants will be assigned 1:1 to receive either Collagenase injection or surgery (limited fasciectomy). We aim to recruit 710 adult participants with Dupuytren’s contracture. Potential participants will be identified in primary and secondary care, screened by a delegated clinician and if eligible and consenting, baseline data will be collected and randomisation completed. The primary outcome will be the self-reported Patient Evaluation Measure assessed at 1 year after treatment. Secondary outcome measures include the Unité Rhumatologique des Affections de la Main Scale, the Michigan Hand Questionnaire, EQ-5D-5L, resource use, further procedures, complications, recurrence, total active movement and extension deficit, and time to return to function. Given the limited evidence comparing recurrence rates following Collagenase injection and limited fasciectomy, and the importance of a return to function as soon as possible for patients, the associated measures for each will be prioritised to allow treatment effectiveness in the context of these key elements to be assessed. An economic evaluation will assess the cost effectiveness of treatments and a qualitative sub-study will assess participants experiences and preferences of the treatments. Discussion: The DISC trial is the first randomised controlled trial, to our knowledge, to investigate the clinical and cost effectiveness of Collagenase compared to limited fasciectomy surgery for patients with Dupuytren’s contracture.

Highlights From the Annual Meeting of the American Epilepsy Society 2022

With more than 6000 attendees between in-person and virtual offerings, the American Epilepsy Society Meeting 2022 in Nashville, felt as busy as in prepandemic times. An ever-growing number of physicians, scientists, and allied health professionals gathered to learn a variety of topics about epilepsy. The program was carefully tailored to meet the needs of professionals with different interests and career stages. This article summarizes the different symposia presented at the meeting. Basic science lectures addressed the primary elements of seizure generation and pathophysiology of epilepsy in different disease states. Scientists congregated to learn about anti-seizure medications, mechanisms of action, and new tools to treat epilepsy including surgery and neurostimulation. Some symposia were also dedicated to discuss epilepsy comorbidities and practical issues regarding epilepsy care. An increasing number of patient advocates discussing their stories were intertwined within scientific activities. Many smaller group sessions targeted more specific topics to encourage member participation, including Special Interest Groups, Investigator, and Skills Workshops. Special lectures included the renown Hoyer and Lombroso, an ILAE/IBE joint session, a spotlight on the impact of Dobbs v. Jackson on reproductive health in epilepsy, and a joint session with the NAEC on coding and reimbursement policies. The hot topics symposium was focused on traumatic brain injury and post-traumatic epilepsy. A balanced collaboration with the industry allowed presentations of the latest pharmaceutical and engineering advances in satellite symposia
