Housing for Student Teachers in Rural School Districts

This project imagines an architectural solution to the educational gap rural East Texas school districts face. Texas is suffering from a shortage of teachers, many teachers are exiting the profession and fewer are completing certification programs to enter into the profession. The effects of this are significantly more detrimental in smaller school districts. IntraHousing proposes an alternative form of housing for these  districts to recruit and retain graduate student- and newly hired- teachers. Offering housing to teachers is one way smaller districts can compete with larger urban centers. This idea has precedents; for example, Marfa Independent School District renovated an unused administrative building and army barrack to create apartments for attracting teachers. This project, based in Caldwell, Texas, builds on Marfa’s example to provide an architectural, financial, and institutional “kit-of-parts” that could be realized in other East Texas towns facing similar issues. In addition to the well-known formal investigation of the “nine square problem,” John Hejduk, in his Seven Texas Houses, envisioned the architectural program of the house as a list of typical domestic spaces. This project used Hejduk’s list of spaces as the basis of a survey sent to teachers across Texas. The survey asked teachers to convey their level of comfort in sharing these spaces. The results showed teachers were willing to share spaces often considered private, and it also indicated a need for spaces dedicated to teaching preparation. These programmatic results were combined with a formal study of the Texas urban grid for the purpose of integrating student teacher housing in small town centers. These architectural strategies are supported by a theoretical framework that outlines the various institutional and financial conditions required to realize this proposal. This project hopes to be a solution for the pressing needs in rural housing and education

Pelagic Habitat Use by Juvenile Reef Fishes in the Gulf of Mexico

The assemblage composition, abundance, frequency of occurrence, and vertical distribution of juvenile reef fishes in the offshore pelagic habitat of the northern Gulf of Mexico are described. This study, a component of the NOAA-supported Offshore Nekton Sampling and Analysis Program, is the first to examine juvenile reef fish distributions across the oceanic northern Gulf of Mexico after the Deepwater Horizon oil spill. Results presented here are derived from a 3-month, spring/summer research cruise in 2011 on the M/V Meg Skansi. A 10-m2 MOCNESS midwater trawl was used to sample 45 stations from the surface to a depth of 1500 m, both day and night. Seven reef fish orders, 30 reef fish families and 119 reef fish species were collected. Initial analysis has revealed the presence of juveniles of some species in locations where adults are not known to occur. Juveniles were found almost exclusively in the uppermost 200m of the water column. A greater number of individuals were collected in nighttime trawls. Surprisingly, some individuals were sampled between 1000–1500 m. During the MS7 sampling program, hydrographic profiles of the water column were recorded. This information provides the hydrographic background setting against which the coastal reef fish distributions in the offshore pelagic habitat of the Gulf of Mexico can be characterized. Results of fish distributions as a function of location (relative to the shelf break) and major mesoscale oceanographic features will be presented

Facilitators and Barriers to Nurse Practitioners’ Full Practice Authority in Primary Care in Mississippi

Nurse practitioners in the state of Mississippi are currently required to maintain a collaborating agreement with a physician to practice, despite being educated and obtaining national certification. This limitation of practice further limits patients from obtaining healthcare, especially in rural communities. The present study examined the effects that current practice restrictions have on nurse practitioners providing primary care to patients in the state of Mississippi amid a physician shortage. Surveys were distributed to primary care providers, including nurse practitioners and physicians throughout the state of Mississippi, and a total of 14 physicians (MDs and DOs) and 146 nurse practitioners responded to the survey. Survey results revealed that almost half of the NPs who responded have either considered leaving the field of nurse practitioner or have considered relocating to a full practice authority state due to state restrictions in Mississippi, which would decrease access to primary care even further. The study also revealed that of the nurse practitioners that responded to the survey, the majority stated they rarely consulted with their collaborating physician. This causes an increase in expenses for the nurse practitioner and proves to be yet another barrier in accessing care

Connectivity of Coastal and Oceanic Ecosystems: Pelagic Habitat Use by Juvenile Reef Fishes in the Gulf of Mexico

The assemblage structure, abundance, biomass, and vertical distribution of juvenile reef fishes in the offshore pelagic habitat of the northern Gulf of Mexico are described as part of the NOAA-supported Offshore Nekton Sampling and Analysis Program. The results presented here are from a 3-month, continuous sampling series in 2011 in which discrete depth strata from 0 to 1500 m were sampled using a 10-m2 MOCNESS midwater trawl. This is the first study to examine pelagic juvenile reef fish distributions across the entire oceanic northern Gulf of Mexico seaward of the continental shelf break after the Deepwater Horizon Oil Spill. During this series, 87,407 specimens were collected, of which 838 were reef fishes, representing seven orders, 30 families and 119 species. The faunal composition of pelagic juvenile reef fishes was diverse and well mixed, with no discernable spatial structure with respect to water masses and solar cycle. Seventy-nine percent of the pelagic juvenile reef fishes were collected in the epipelagic and the dominant families were Congridae, Carangidae, Tetraodontidae, and Acanthuridae. Species richness, biomass, and frequency of occurrence of pelagic juvenile reef fishes was greatest between 0-200 m and decreased with depth. Data from the assemblage structure, abundance, biomass, and vertical distribution of pelagic juvenile reef fishes collected from this cruise series will contribute to the lack of knowledge regarding the dispersal dynamics and coastal-connectivity of these fishes in the northern Gulf of Mexico

Mindfulness-based relapse prevention for substance craving.

Craving, defined as the subjective experience of an urge or desire to use substances, has been identified in clinical, laboratory, and preclinical studies as a significant predictor of substance use, substance use disorder, and relapse following treatment for a substance use disorder. Various models of craving have been proposed from biological, cognitive, and/or affective perspectives, and, collectively, these models of craving have informed the research and treatment of addictive behaviors. In this article we discuss craving from a mindfulness perspective, and specifically how mindfulness-based relapse prevention (MBRP) may be effective in reducing substance craving. We present secondary analyses of data from a randomized controlled trial that examined MBRP as an aftercare treatment for substance use disorders. In the primary analyses of the data from this trial, Bowen and colleagues (2009) found that individuals who received MBRP reported significantly lower levels of craving following treatment, in comparison to a treatment-as-usual control group, which mediated subsequent substance use outcomes. In the current study, we extend these findings to examine potential mechanisms by which MBRP might be associated with lower levels of craving. Results indicated that a latent factor representing scores on measures of acceptance, awareness, and nonjudgment significantly mediated the relation between receiving MBRP and self-reported levels of craving immediately following treatment. The mediation findings are consistent with the goals of MBRP and highlight the importance of interventions that increase acceptance and awareness, and help clients foster a nonjudgmental attitude toward their experience. Attending to these processes may target both the experience of and response to craving

HSET Overexpression Fuels Tumor Progression via Centrosome Clustering-Independent Mechanisms in Breast Cancer Patients

Human breast tumors harbor supernumerary centrosomes in almost 80% of tumor cells. Although amplified centrosomes compromise cell viability via multipolar spindles resulting in death-inducing aneuploidy, cancer cells tend to cluster extra centrosomes during mitosis. As a result cancer cells display bipolar spindle phenotypes to maintain a tolerable level of aneuploidy, an edge to their survival. HSET/KifC1, a kinesin-like minus-end directed microtubule motor has recently found fame as a crucial centrosome clustering molecule. Here we show that HSET promotes tumor progression via mechanisms independent of centrosome clustering. We found that HSET is overexpressed in breast carcinomas wherein nuclear HSET accumulation correlated with histological grade and predicted poor progression-free and overall survival. In addition, deregulated HSET protein expression was associated with gene amplification and/or translocation. Our data provide compelling evidence that HSET overexpression is pro-proliferative, promotes clonogenic-survival and enhances cellcycle kinetics through G2 and M-phases. Importantly, HSET co-immunoprecipitates with survivin, and its overexpression protects survivin from proteasome-mediated degradation, resulting in its increased steady-state levels. We provide the first evidence of centrosome clustering-independent activities of HSET that fuel tumor progression and firmly establish that HSET can serve both as a potential prognostic biomarker and as a valuable cancer-selective therapeutic target

Nanophase-photocatalysis: loading, storing, and release of H2O2 using graphitic carbon nitride

A blue light mediated photochemical process using solid graphitic carbon nitride (g-C3N4) in ambient air/isopropanol vapour is suggested to be linked to "nanophase" water inclusions and is shown to produce approx. 50 μmol H2O2 per gram of g-C3N4, which can be stored in the solid g-C3N4 for later release for applications, for example, in disinfection or anti-bacterial surfaces

The Chemerin-CMKLR1 Axis is Functionally important for Central Regulation of Energy Homeostasis

YesChemerin is an adipokine involved in inflammation, adipogenesis, angiogenesis and energy metabolism, and has been hypothesized as a link between obesity and type II diabetes. In humans affected by obesity, chemerin gene expression in peripheral tissues and circulating levels are elevated. In mice, plasma levels of chemerin are upregulated by high-fat feeding and gain and loss of function studies show an association of chemerin with body weight, food intake and glucose homeostasis. Therefore, chemerin is an important blood-borne mediator that, amongst its other functions, controls appetite and body weight. Almost all studies of chemerin to date have focused on its release from adipose tissue and its effects on peripheral tissues with the central effects largely overlooked. To demonstrate a central role of chemerin, we manipulated chemerin signaling in the hypothalamus, a brain region associated with appetite regulation, using pharmacological and genetic manipulation approaches. Firstly, the selective chemerin receptor CMKLR1 antagonist α-NETA was administered i.c.v. to rats to test for an acute physiological effect. Secondly, we designed a short-hairpin-RNA (shRNA) lentivirus construct targeting expression of CMKLR1. This shRNA construct, or a control construct was injected bilaterally into the arcuate nucleus of male Sprague Dawley rats on high-fat diet (45%). After surgery, rats were maintained on high-fat diet for 2 weeks and then switched to chow diet for a further 2 weeks. We found a significant weight loss acutely and inhibition of weight gain chronically. This difference became apparent after diet switch in arcuate nucleus-CMKLR1 knockdown rats. This was not accompanied by a difference in blood glucose levels. Interestingly, appetite-regulating neuropeptides remained unaltered, however, we found a significant reduction of the inflammatory marker TNF-α suggesting reduced expression of CMKLR1 protects from high-fat diet induced neuroinflammation. In white and brown adipose tissue, mRNA expression of chemerin, its receptors and markers of adipogenesis, lipogenesis and brown adipocyte activation remained unchanged confirming that the effects are driven by the brain. Our behavioral analyses suggest that knockdown of CMKLR1 had an impact on object recognition. Our data demonstrate that CMKLR1 is functionally important for the central effects of chemerin on body weight regulation and neuroinflammation.This work was funded in part by the Academy of Medical Sciences, the Wellcome Trust, the Government of Business, Energy and Industrial Strategy and the British Heart Foundation and Diabetes United Kingdom [SBF004/1063] (GH), the Society for Endocrinology Equipment Grant (GH, RD), the University of Bradford (GH, KP, SK) and Nottingham Trent University (RD)

A study of prisms and therapy in attention loss after stroke (SPATIAL): A feasibility randomised controlled trial

Objective: Investigate feasibility and acceptability of prism adaptation training for people with inattention (spatial neglect), early after stroke, during usual care. Design: Phase II feasibility randomised controlled trial with 3:1 stratified allocation to standard occupational therapy with or without intervention, and nested process evaluation. Setting: Ten hospital sites providing in-patient stroke services. Participants: Screened positive for inattention more than one-week post-stroke; informal carers. Occupational therapists participated in qualitative interviews. Intervention: Adjunctive prism adaptation training at the start of standard occupational therapy sessions for three weeks. Main measures: Feasibility measures included recruitment and retention rates, intervention fidelity and attrition. Outcomes collected at baseline, 3 weeks and 12 weeks tested measures including Nottingham Extended Activities of Daily Living Scale. Acceptability was explored through qualitative interviews and structured questions. Results: Eighty (31%) patients were eligible, 57 (71%) consented, 54 randomised (40:13, +1 exclusion) and 39 (74%) completed 12-week outcomes. Treatment fidelity was good: participants received median eight intervention sessions (IQR: 5, 12) lasting 4.7 min (IQR: 4.1, 5.0). All six serious adverse events were unrelated. There was no signal that patients allocated to intervention did better than controls. Twenty five of 35 recruited carers provided outcomes with excellent data completeness. Therapists, patients and carers found prism adaptation training acceptable. Conclusions: It is feasible and acceptable to conduct a high-quality definitive trial of prism adaptation training within occupational therapy early after stroke in usual care setting, but difficult to justify given no sign of benefit over standard occupational therapy.

Respiratory Syncytial Virus Disease Burden in Community-Dwelling and Long-Term Care Facility Older Adults in Europe and the United States: A Prospective Study

Background. Data on respiratory syncytial virus (RSV) disease burden in adults remain scarce. We assessed the burden of confirmed RSV-acute respiratory infections (cRSV-ARIs) in community-dwelling (CD) adults and those in long-term care facilities (LTCFs).Methods. In this prospective cohort study covering 2 RSV seasons (October 2019-March 2020 and October 2020-June 2021), RSVARIs were identified through active surveillance, in medically stable CD-adults =50 years (Europe) or adults =65 years in LTCFs (Europe and the United States). RSV infection was confirmed by polymerase chain reaction from combined nasal and throat swabs.Results. Of 1981 adults enrolled, 1251 adults in CD and 664 LTCFs (season 1) and 1223 adults in CD and 494 LTCFs (season 2) were included in the analyses. During season 1, overall incidence rates ([IRs] cases/1000 person-years) and attack rates (ARs) for cRSVARIs were 37.25 (95% confidence interval [CI], 22.62-61.35) and 1.84% in adults in CD and 47.85 (CI, 22.58-101.4) and 2.26% in adults in LTCFs. Complications occurred for 17.4% (CD) and 13.3% (LTCFs) of cRSV-ARIs. One cRSV-ARI occurred in season 2 (IR = 2.91 [CI, 0.40-20.97]; AR = 0.20%), without complications. No cRSV-ARIs led to hospitalization or death. Viral pathogens were codetected in =17.4% of cRSV-ARIs.Conclusions. RSV is an important cause of disease burden in adults in CD and LTCFs. Despite the observed low severity of cRSVARI, our results support the need for RSV prevention strategies among adults =50 years old
