The Impact of Trauma-Sensitive Yoga on Persons Who Are Incarcerated: Identifying, Understanding, and Controlling Emotions.

BACKGROUND: While persons who are incarcerated have high rates of previous trauma, further traumatization can result from the experience of incarceration. The inability to effectively process trauma can lead to maladaptive behavior, a serious concern for correctional administrators. Acquiring the skills to regulate emotions and mitigate feelings of impulsivity help persons who are incarcerated take responsibility for their actions to make better decisions, simultaneously encouraging prosocial behavior, decreasing institutional misconduct, and reducing behaviors that place one at risk for repeated involvement in the criminal justice system. PURPOSE: Trauma-sensitive yoga (TSY) is one correctional intervention that can effectively address misconduct issues. Yet, the specific impact of TSY on populations who are incarcerated has not been empirically investigated. METHODS: A mixed-methods study, utilizing pretest and posttest interviewing, was conducted with male residents in a New York jail who completed a 4-week TSY program. RESULTS: Data indicated that those who participated in TSY experienced statistically significant improvements in self-esteem, self-control, resilience, institutional conduct, self-efficacy, and emotion regulation. Qualitative data also indicated high levels of connectivity with other TSY class participants. IMPLICATIONS: This research implies that cost-effective interventions like TSY have the ability to produce beneficial outcomes within a short time, which is integral to furthering rehabilitative efforts within the transient nature of the jail setting.

Coping with Depression, Anxiety & Stress: The Healing Effects of a Jail-Based Trauma Sensitive Yoga Program.

Stress, anxiety and depression, often linked to internalizing/externalizing behaviors, are remarkedly high in a jail-based setting when one's future is uncertain. While research demonstrates that carceral yoga programs can provide physiological/psychological benefits, persons who are incarcerated, who have high rates of trauma-related experiences and mental illness, might benefit more from a trauma sensitive approach. Empirical studies examining the specific impact of trauma sensitive yoga (TSY) on populations who are incarcerated appear unavailable, necessitating this exploratory investigation with male residents in a TSY intervention at a New York jail. Through pre and post-test interviewing and a mixed methods data analysis, data indicated that those who participated in TSY experienced statistically significant increases in overall health, in addition to statistically significant reductions in stress, anxiety, depression and institutional misconduct. Qualitative analyses suggested that male participants experienced transcendence of the jail environment, easing the monotony of the correctional setting. TSY also provided them with new opportunities, the ability to regulate emotions/behaviors and initiate personal growth/changes within. Hence, this research implies that TSY, a benign intervention, easily implemented in a correctional setting, has the ability to beget benefits for persons who are incarcerated within a short period of time. This is vital to providing rehabilitative options within the transient nature of the jail setting.

Compost Dairy Barn Layout and Management Recommendations in Kentucky: A Descriptive Study.

This study was conducted to describe the building layout and dimensions, characterize the bedding material, and observe the management practices in 42 compost-bedded pack (CBP) barns in Kentucky (USA). The average herd size found in the study was 90 cows and the breeds consisted of Jersey (6.8%), Holstein (72.7%), and mixed (20.5%). The average CBP barn dimensions were 49.1 m (length) by 21.9 m (width). Many of these barns had feed alleys and driveways; overshot ridges with frequent orientation from NE to SW; and green sawdust, kiln-dried sawdust, or a mixture of both as the most common bedding materials. The bed-turning process was performed mechanically at depths of less than 0.25 m, and the loading of fresh material was performed every one to five weeks, varying by season, weather conditions, barn size, and cow density. The average bedding moisture content was found to be 59.0% (wet bulb-w.b.) and ranged from 36.2 to 71.8%. Coliforms were not present in barns that had a higher compost temperature, and the E. coli, Bacillus, and Streptococcus counts were higher in the barns that had a lower moisture content. In conclusion, it was observed that heterogeneous management was used among the barns and that the producers were satisfied with the compost barn system.

Determination of Thermal, Chemical and Physical Properties of Bedding Materials for Compost Dairy Barns.

The thermal, chemical, and physical properties of compost bedding materials play an important role in every phase of compost production. Based on this, we aimed to assess the thermal, chemical and physical properties of bedding materials for compost-bedded pack (CBP) barns. The database for this study was registered from 42 CBP barns, distributed throughout the state of Kentucky (USA). The thermal conductivity showed a linear relationship with moisture content and bulk density, while thermal resistivity decreased with increasing particle size. The bedding moisture average was 46.8% (±11.5). The average finer index (p < 0.05) was the highest weight percentage (30.1%) in the samples studied. Water-holding capacity (WHC) increased with increasingly fine particle size. The higher bulk density value was 3.6 times that of the lowest bulk density value. The chemical characterization of the bedding material provided the following results: 42.7% (±3.8%) C, 1.6% (±0.4%) N, and 28.2 (±8.0) C:N ratio. However, thermal properties are strongly dependent on particle size. Producers can use the bedding material as fertilizer in their crops, due to the chemical characteristics of the materials. Beds with good physical and chemical properties improve their moisture content.

A Cytoplasmic Receptor-like Kinase Contributes to Salinity Tolerance.

Receptor-like cytoplasmic kinases (RLCKs) are receptor kinases that lack extracellular ligand-binding domains and have emerged as a major class of signaling proteins that regulate plant cellular activities in response to biotic/abiotic stresses and endogenous extracellular signaling molecules. We have identified a rice RLCK (OsRLCK311) that was significantly higher in transgenic pSARK-IPT rice (Oryza sativa) that exhibited enhanced growth under saline conditions. Overexpression of OsRLCK311 full-length protein (RLCK311FL) and the C-terminus of OsRLCK311 (ΔN) in Arabidopsis confirmed its role in salinity tolerance, both in seedlings and mature plants. Protein interaction assays indicated that OsRLCK311 and ΔN interacted in-vivo with the plasma membrane AQP AtPIP2;1. The RLCK311-PIP2;1 binding led to alterations in the stomata response to ABA, which was characterized by more open stomata of transgenic plants. Moreover, OsRLCK311-ΔN effect in mediating enhanced plant growth under saline conditions was also observed in the perennial grass Brachypodium sylvaticum, confirming its role in both dicots and monocots species. Lastly, OsRLCK311 interacted with the rice OsPIP2;1. We suggest that the rice OsRLCK311 play a role in regulating the plant growth response under saline conditions via the regulation of the stomata response to stress. This role seems to be independent of the RLCK311 kinase activity, since the overexpression of the RLCK311 C-terminus (ΔN), which lacks the kinase full domain, has a similar phenotype to RLCK311FL.

DNA-based Determination of Ancestry in Cynomolgus Macaques (Macaca fascicularis).

Interest in the genetic composition of cynomolgus macaques (Macaca fascicularis) has increased due to the rising demand for NHP models in human biomedical research. Significant genetic differences among regional populations of cynomolgus macaques can confound interpretations of research results because they do not solely reflect differences in experimental treatment effects. Therefore, the common origin of cynomolgus macaques used as research subjects should be verified by using region-specific genetic markers to minimize the influence of underlying genetic variation among animals selected as research subjects on phenotypes under study. We compared the effectiveness of 18 short tandem repeat (STR) markers with that of 83 single-nucleotide polymorphism (SNP) markers to differentiate the ancestry of cynomolgus macaques from 6 different populations (Cambodia, Sumatra, Mauritius, Singapore, and the islands of Luzon and Zamboanga in the Philippines). Genetic diversity indices such as allele numbers and expected heterozygosity based on SNP were lower and exhibited lower standard errors than those provided by STR, probably because, unlike STR, most SNP are biallelic and consequently exhibit maximal expected heterozygosity values of 0.50. However, the standard error of estimates of observed heterozygosity based on SNP was higher than that for STR, perhaps reflecting sampling errors. Only 27 SNP were required to match the resolving power of 17 STR to detect population structure, that is, 1.6 SNP:1 STR. Whereas STR only differentiated the Mauritian population from all other populations, SNP detected 4 genetically distinct groups (Cambodia, Singapore-Sumatra, Mauritius, and Zamboanga). SNP are poised to become as valuable as STR for understanding and detecting genetic structure among cynomolgus macaques. Although STR will remain an important tool for cynomolgus macaque population studies, SNP have the potential to become the mainstream marker type.

Moisture effects on greenhouse gases generation in nitrifying gas-phase compost biofilters.

Gas-phase compost biofilters are extensively used in concentrated animal feeding operations to remove odors and, in some cases, ammonia from air sources. The expected biochemical pathway for these predominantly aerobic systems is nitrification. However, non-uniform media with low oxygen levels can shift biofilter microbial pathways to denitrification, a source of greenhouse gases. Several factors contribute to the formation of anoxic/anaerobic zones: media aging, media and particle structure, air velocity distribution, compaction, biofilm thickness, and moisture content (MC) distribution. The present work studies the effects of media moisture conditions on ammonia (NH(3)) removal and greenhouse gas generation (nitrous oxide, N(2)O and methane, CH(4)) for gas-phase compost biofilters subject to a 100-day controlled drying process. Continuous recordings were made for the three gases and water vapor (2.21-h sampling cycle, each cycle consisted of three gas species, and water vapor, for a total of 10,050 data points). Media moisture conditions were classified into three corresponding media drying rate (DR) stages: Constant DR (wetter media), falling DR, and stable-dry system. The first-half of the constant DR period (0-750 h; MC=65-52%, w.b.) facilitated high NH(3) removal rates, but higher N(2)O generation and no CH(4) generation. At the drier stages of the constant DR (750-950 h; MC=52-48%, w.b.) NH(3) removal remained high but N(2)O net generation decreased to near zero. In the falling DR stage (1200-1480 h; MC=44-13%) N(2)O generation decreased, CH(4) increased, and NH(3) was no longer removed. No ammonia removal or greenhouse gas generation was observed in the stable-dry system (1500-2500 h; MC=13%). These results indicate that media should remain toward the drier region of the constant DR (in close proximity to the falling DR stage; MC=50%, approx.), to maintain high levels of NH(3) removal, reduced levels of N(2)O generation, and nullify levels of CH(4) generation.

Imaging C-Fos Gene Expression in Burns Using Lipid Coated Spion Nanoparticles.

MR imaging of gene transcription is important as it should enable the non-invasive detection of mRNA alterations in disease. A range of MRI methods have been proposed for in vivo molecular imaging of cells based on the use of ultra-small super-paramagnetic iron oxide (USPIO) nanoparticles and related susceptibility weighted imaging methods. Although immunohistochemistry can robustly differentiate the expression of protein variants, there is currently no direct gene assay technique that is capable of differentiating established to differentiate the induction profiles of c-Fos mRNA in vivo. To visualize the differential FosB gene expression profile in vivo after burn trauma, we developed MR probes that link the T2* contrast agent [superparamagnetic iron oxide nanoparticles (SPION)] with an oligodeoxynucleotide (ODN) sequence complementary to FosB mRNA to visualize endogenous mRNA targets via in vivo hybridization. The presence of this SPION-ODN probe in cells results in localized signal reduction in T2*-weighted MR images, in which the rate of signal reduction (R2*) reflects the regional iron concentration at different stages of amphetamine (AMPH) exposure in living mouse tissue. Our aim was to produce a superior contrast agent that can be administered using systemic as opposed to local administration and which will target and accumulate at sites of burn injury. Specifically, we developed and evaluated a PEGylated lipid coated MR probe with ultra-small super-paramagnetic iron oxide nanoparticles (USPION, a T2 susceptibility agent) coated with cationic fusogenic lipids, used for cell transfection and gene delivery and covalently linked to a phosphorothioate modified oligodeoxynucleotide (sODN) complementary to c-Fos mRNA (SPION-cFos) and used the agent to image mice with leg burns. Our study demonstrated the feasibility of monitoring burn injury using MR imaging of c-Fos transcription in vivo, in a clinically relevant mouse model of burn injury for the first time.

Is it real? Can we win? Is it worth doing? Managing risk and reward in an innovation portfolio.

Minor innovations make up most of a company's development portfolio, on average, but they never generate the growth companies seek. The solution, says Day--the Geoffrey T. Boisi Professor of Marketing and a codirector of the Mack Center for Technological Innovation at Wharton--is for companies to undertake a systematic, disciplined review of their innovation portfolios and increase the number of major innovations at an acceptable level of risk. Two tools can help them do this. The first, called the risk matrix, graphically reveals the distribution of risk across a company's entire innovation portfolio. The matrix allows companies to estimate each project's probability of success or failure, based on how big a stretch it is for the firm to undertake. The less familiar the product or technology and the intended market, the higher the risk. The second tool, dubbed the R-W-W (real-win-worth it) screen, allows companies to evaluate the risks and potential of individual projects by answering six fundamental questions about each one: Is the market real? Explores customers' needs, their willingness to buy, and the size of the potential market. Is the product real? Looks at the feasibility of producing the innovation. Can the product be competitive? and Can our company be competitive? Investigate how well suited the company's resources and management are to compete in the marketplace with the product. Will the product be profitable at an acceptable risk? Explores the financial analysis needed to assess an innovation's commercial viability. Last, Does launching the product make strategic sense? examines the project's fit with company strategy and whether management supports it.

Scanning the periphery.

Companies often face new rivals, technologies, regulations, and other environmental changes that seem to come out of left field. How can they see these changes sooner and capitalize on them? Such changes often begin as weak signals on what the authors call the periphery, or the blurry zone at the edge of an organization's vision. As with human peripheral vision, these signals are difficult to see and interpret but can be vital to success or survival. Unfortunately, most companies lack a systematic method for determining where on the periphery they should be looking, how to interpret the weak signals they see, and how to allocate limited scanning resources. This article provides such a method-a question-based framework for helping companies scan the periphery more efficiently and effectively. The framework divides questions into three categories: learning from the past (What have been our past blind spots? What instructive analogies do other industries offer? Who in the industry is skilled at picking up weak signals and acting on them?); evaluating the present (What important signals are we rationalizing away? What are our mavericks, outliers, complainers, and defectors telling us? What are our peripheral customers and competitors really thinking?); and envisioning the future (What future surprises could really hurt or help us? What emerging technologies could change the game? Is there an unthinkable scenario that might disrupt our business?). Answering these questions is a good first step toward anticipating problems or opportunities that may appear on the business horizon. The article concludes with a self-test that companies can use to assess their need and capability for peripheral vision.

Identification of a novel calpain inhibitor using phage display.

Calpains are calcium- and thiol-dependent proteases that cleave a variety of intracellular substrates. Overactivation of the calpains has been implicated in a number of diseases and conditions such as ischemic stroke indicating a need for the development of calpain inhibitors. A major problem with current calpain inhibitors has been specific targeting to calpain. To identify highly specific calpain interacting peptides, we developed a peptide-phage library screening method based on the calcium-dependent conformation change associated with calpain activation. A phage-peptide library representing greater than 2 billion expressed 12-mers was incubated with calpain I in the presence of calcium. The calcium-dependent bound phage was then eluted by addition of EGTA. After four rounds of selection we found a conserved 5-mer sequence represented by LSEAL. Synthetic LSEAL inhibited tau-calpain interaction and in vitro proteolysis of tau- and alpha-synuclein by calpains. Deletion of the portion of the tau protein containing a homologous sequence to LSEAL resulted in decreased calpain-mediated tau degradation. These data suggest that these peptides may represent novel calpastatin mimetics.

Distinct cleavage patterns of normal and pathologic forms of alpha-synuclein by calpain I in vitro.

Parkinson's disease (PD) is characterized by fibrillary neuronal inclusions called Lewy bodies (LBs) consisting largely of alpha-synuclein (alpha-syn), the protein mutated in some patients with familial PD. The mechanisms of alpha-syn fibrillization and LB formation are unknown, but may involve aberrant degradation or turnover. We examined the ability of calpain I to cleave alpha-syn in vitro. Calpain I cleaved wild-type alpha-syn predominantly after amino acid 57 and within the non-amyloid component (NAC) region. In contrast, calpain I cleaved fibrillized alpha-syn primarily in the region of amino acid 120 to generate fragments like those that increase susceptibility to dopamine toxicity and oxidative stress. Further, while calpain I cleaved wild-type alpha-syn after amino acid 57, this did not occur in mutant A53T alpha-syn. This paucity of proteolysis could increase the stability of A53T alpha-syn, suggesting that calpain I might protect cells from forming LBs by specific cleavages of soluble wild-type alpha-syn. However, once alpha-syn has polymerized into fibrils, calpain I may contribute to toxicity of these forms of alpha-syn by cleaving at aberrant sites within the C-terminal region. Elucidating the role of calpain I in the proteolytic processing of alpha-syn in normal and diseased brains may clarify mechanisms of neurodegenerative alpha-synucleinopathies.

Prenatal diagnosis of factor X deficiency using a combination of direct mutation detection and linkage analysis with an intragenic single nucleotide polymorphism.

OBJECTIVE: To present a family in which it was possible to perform prenatal diagnosis for recessively inherited factor X deficiency using both direct mutation detection as well as linkage analysis. METHODS: In a family where both parents were known to be carriers of factor X deficiency, fetal DNA was obtained from an ongoing pregnancy by CVS in the first trimester. Direct DNA sequencing was used to detect a previously identified factor X mutation, and linkage analysis using a single nucleotide polymorphism (SNP) was used to follow the segregation of the other parent's factor X alleles. RESULTS: Our studies predicted the fetus in question to be a heterozygote carrier of factor X deficiency, and this was demonstrated to be correct at birth. CONCLUSIONS: This is the first reported case of prenatal diagnosis of factor X deficiency. In addition, this case demonstrates the remarkable utility of SNPs in linkage analysis of rare genetic disorders.
