Guidelines for Cleaning up Former Methamphetamine Labs, June 2009

Methamphetamine (meth) drug labs are not a new hazard to Iowa. In 2004, federal, state and local authorities seized more than 1,400 Iowa labs. These labs are discovered in houses, apartments, motel rooms, motor vehicles, and even an occasional combine. A dramatic decrease in the number of meth labs occurred in 2005 when a law restricting the purchase of pseudoephedrine was implemented. Although the number of meth labs has decreased, they continue to exist. Since there is currently no official federal guidance or regulations on how to clean up a former meth lab, the Iowa Department of Public Health, Division of Environmental Health, has created these basic guidelines to assist public health officials, property owners and the general public in cleaning up former meth lab properties.

Time-scale and other invariants of integrative mechanical behavior in living cells.

In dealing with systems as complex as the cytoskeleton, we need organizing principles or, short of that, an empirical framework into which these systems fit. We report here unexpected invariants of cytoskeletal behavior that comprise such an empirical framework. We measured elastic and frictional moduli of a variety of cell types over a wide range of time scales and using a variety of biological interventions. In all instances elastic stresses dominated at frequencies below 300 Hz, increased only weakly with frequency, and followed a power law; no characteristic time scale was evident. Frictional stresses paralleled the elastic behavior at frequencies below 10 Hz but approached a Newtonian viscous behavior at higher frequencies. Surprisingly, all data could be collapsed onto master curves, the existence of which implies that elastic and frictional stresses share a common underlying mechanism. Taken together, these findings define an unanticipated integrative framework for studying protein interactions within the complex microenvironment of the cell body, and appear to set limits on what can be predicted about integrated mechanical behavior of the matrix based solely on cytoskeletal constituents considered in isolation. Moreover, these observations are consistent with the hypothesis that the cytoskeleton of the living cell behaves as a soft glassy material, wherein cytoskeletal proteins modulate cell mechanical properties mainly by changing an effective temperature of the cytoskeletal matrix. If so, then the effective temperature becomes an easily quantified determinant of the ability of the cytoskeleton to deform, flow, and reorganize.

Scaling the microrheology of living cells

We report a scaling law that governs both the elastic and frictional properties of a wide variety of living cell types, over a wide range of time scales and under a variety of biological interventions. This scaling identifies these cells as soft glassy materials existing close to a glass transition, and implies that cytoskeletal proteins may regulate cell mechanical properties mainly by modulating the effective noise temperature of the matrix. The practical implications are that the effective noise temperature is an easily quantified measure of the ability of the cytoskeleton to deform, flow, and reorganize.

Cell differentiation to "mating bodies" induced by an integrating and conjugative element in free-living bacteria.

Lateral gene transfer (LGT) is one of the most important processes leading to prokaryotic genome innovation. LGT is typically associated with conjugative plasmids and bacteriophages, but recently, a new class of mobile DNA known as integrating and conjugative elements (ICE) was discovered, which is abundant and widespread among bacterial genomes. By studying at the single-cell level the behavior of a prevalent ICE type in the genus Pseudomonas, we uncover the remarkable way in which the ICE orchestrates host cell differentiation to ensure horizontal transmission. We find that the ICE induces a state of transfer competence (tc) in 3%-5% of cells in a population under nongrowing conditions. ICE factors control the development of tc cells into specific assemblies that we name "mating bodies." Interestingly, cells in mating bodies undergo fewer and slower division than non-tc cells and eventually lyse. Mutations in ICE genes disrupting mating-body formation lead to 5-fold decreased ICE transfer rates. Hence, by confining the tc state to a small proportion of the population, ICE horizontal transmission is achieved with little cost in terms of vertical transmission. Given the low transfer frequencies of most ICE, we anticipate regulation by subpopulation differentiation to be widespread.

Iowa's Living Roadway Plant Profiler, August 21, 2003

This publication is a guide to understanding the Iowa Department of Transportation’s roadside management programs. It offers descriptions of various landscape designs or planting styles used within or adjacent to Iowa’s highway rights-of-way, as well as various plant profiles. In addition, this guide will help you learn more about the value of plants and their contribution to our environment and society. This publication is written for persons having little or no formal training in botany, and technical terminology has been kept to the minimum necessary to maintain standards of accuracy and conciseness in the descriptions. Plants are known by common names and botanical names. Most people prefer to use common names because they are easier to spell and say. Both have been used in this publication. Botanical names are taken from Latin, Greek or “Latinized” words of other languages. Each plant species has a unique botanical name, consisting of the genus, followed by the species. Some botanical names contain additional words after the species name to designate cultivars or subspecies. Plant species are grouped into families by flower structure. Family names are Latin, so the associated common family names are included in parenthesis. Sources of information for this publication are not cited within the text to save space, avoid repetition and make it more readable. However, all references used are included in the bibliography at the end of this publication.

Physical activity under confinement and free-living conditions.

The objective of this study was to investigate the relationship between the physical activity (PA) and its related variables under confinement and in free-living conditions in Asian individuals, where no such information presently exists. The subjects consisted of eighty-six Japanese individuals with a mean age of 38+/-12 years. Under confinement in a large respiratory chamber, the energy expenditure (EE) was measured for 24h. In addition, two moderate walking exercises of 30 min each on a horizontal treadmill were assigned. Free-living measurements of 7 days were also performed using a validated accelerometer. The PA level in the chamber (1.47+/-0.11), expressed as a multiple of the basal EE, was lower than that in free-living conditions (1.53+/-0.12) (p<0.001). However, the two values were closely correlated (r=0.744, p<0.001). Conversely, a residual analysis showed a wide variation in the mean difference for both conditions and revealed a significant systematic error (r=-0.548, p<0.001), thus indicating an increased gap with increasing PA levels in free-living conditions. Similar results were obtained following the exclusion of the imposed exercise sessions. In contrast, the daily step counts under both conditions did not show any correlation. The PA level in the chamber (including and excluding imposed walking exercises) is compatible with the PA level in free-living conditions at the group level, although the daily step counts are unrelated. Thus, the PA level in the chamber may provide valuable information to help us achieve a better understanding of human PA in daily life as it is related to behavioral research.

HIV disclosure and nondisclosure among migrant women from sub-Saharan Africa living in Switzerland.

No study to date has focused specifically on the reasons for and against disclosure of HIV-positive status among sub-Saharan migrant women. Thirty HIV-positive women from 11 sub-Saharan countries living in French-speaking Switzerland participated in semi-structured individual interviews. The reasons women reported for disclosure or nondisclosure of their HIV serostatus were classified into three categories: social, medical, and ethical. The women identified the stigma associated with HIV as a major social reason for nondisclosure. However, this study identifies new trends related to disclosure for medical and ethical reasons. Being undetectable played an important role in the life of sub-Saharan migrant women, and analysis revealed their medical reasons for both disclosure and nondisclosure. Disclosure to new sexual partners occurred when women had a more positive perception about HIV and when they believed themselves to be in a long-term relationship. Women reported nondisclosure to family members when they did not need help outside the support provided by the medical and social fields. The results on ethical reasons suggested that challenging stigma was a reason for disclosure. Since the women' perceptions on HIV changed when they came to see it as a chronic disease, disclosure occurred in an attempt to normalize life with HIV in their communities in migration and to challenge racism and discrimination. Our findings can help health providers better understand the communication needs of sub-Saharan migrant women with respect to HIV/AIDS and sexuality and offer them adequate disclosure advice that takes into account migration and gender issues.

Scaffold attachment factor B1 directly interacts with nuclear receptors in living cells and represses transcriptional activity.

Transcriptional activity relies on coregulators that modify the chromatin structure and serve as bridging factors between transcription factors and the basal transcription machinery. Using the DE domain of human peroxisome proliferator-activated receptor gamma (PPARgamma) as bait in a yeast two-hybrid screen of a human adipose tissue library, we isolated the scaffold attachment factor B1 (SAFB1/HET/HAP), which was previously shown to be a corepressor of estrogen receptor alpha. We show here that SAFB1 has a very broad tissue expression profile in human and is also expressed all along mouse embryogenesis. SAFB1 interacts in pull-down assays not only with PPARgamma but also with all nuclear receptors tested so far, albeit with different affinities. The association of SAFB1 and PPARgamma in vivo is further demonstrated by fluorescence resonance energy transfer (FRET) experiments in living cells. We finally show that SAFB1 is a rather general corepressor for nuclear receptors. Its change in expression during the early phases of adipocyte and enterocyte differentiation suggests that SAFB1 potentially influences cell proliferation and differentiation decisions.

Role of intra-operative duplex ultrasound in living renal donor transplantation

Objective: The treatment of choice in end-stage renal disease is¦transplantation.¦Hemodynamic disturbances can evoke graft loss, while early ultrasound¦identification of vascular problems improves outcome. The primary endpoint¦of this study was to identify differences in post-op complications with and¦without systematic, intraoperative Doppler ultrasound use. A secondary aim¦was to find a predictive resistance index limit which would show where surgical¦reintervention was necessary.¦Methods: Between Jan 2000 and Dec 2010, 108 renal transplants were¦performed from living donors at our institution. In group 1 (n = 67),¦intra-operative duplex ultrasound and intra-parenchymatous resistance index¦measurements assessed patients, while in group 2 (n = 41), no ultrasound was¦performed.¦Results. There were no inter-group differences in the overall post-op¦complication rate or in benefit to graft or patient survival with Doppler use,¦however, significantly more vascular complications (10% vs. 0%, p = 0·02) and¦more acute rejections (37% vs. 10%) occurred in group 2 than in group 1,¦respectively. When the resistance index was <0·5 intra-operatively, immediate¦surgical revision was undertaken to raise the index >0·6.¦Results: There were no inter-group differences in the overall post-op¦complication rate or in benefit to graft or patient survival with Doppler use,¦however, significantly more vascular complications (10% vs. 0%, p = 0·02) and¦more acute rejections (37% vs. 10%) occurred in group 2 than in group 1,¦respectively. When the resistance index was <0·5 intra-operatively, immediate¦surgical revision was undertaken to raise the index >0·6.¦Conclusion: This is the first report demonstrating benefits of systematic¦intraoperative Doppler ultrasound on post-operative complications in renal¦transplantation from living donors. Our results support surgical revision with a¦resistance index <0·5.
