Collecting and Curating in Liberia and the United States: William Siegmann and Liberian Material Culture at the Fair and in the Museum
Authors: Beck Cohen Stephanie 
Published: March 2018

AbstractMuseums mediate diverse and sometimes contentious cultural and political histories. For Liberian collections, museum work negotiates Indigenous and trans‐Atlantic material cultures. Inspired by the Liberian collections at the Smithsonian Institution's National Museum of Natural History and the 2014 exhibit Visions from the Forests: The Art of Liberia and Sierra Leone, this article considers the curatorial work of the Brooklyn Museum's William Siegmann, who shaped the exhibition of Liberian art in the second half of the twentieth century. Siegmann's work reflected an interdisciplinary spirit; his exhibitions between 1974 and 1987 adapted to different contexts and audiences, yielding distinctions in how Liberian art was presented in museums during a period of political and cultural turmoil. Examining Siegmann's curatorial projects through collections in Liberia and Washington, D.C., together with archival documents from the Siegmann collections at Indiana University, illustrates how one scholar‐collector influenced knowledge development about Liberian material culture.

Published: March 2018

Summary

Fine roots of woody plants comprise multiple root orders, which can be functionally partitioned into two pools: absorptive fine roots (AFRs, orders 1, 2) and transport fine roots (TFRs, orders 3–5). However, the function‐based fine‐root dynamics and especially their responses to increased nitrogen (N) availability remain unclear.

We explored dynamic responses of both AFRs and TFRs of Pinus elliottii to N addition in subtropical China based on a 4‐yr minirhizotron experiment and a two‐stage – early (0.5 yr) vs late (4 yr) – decomposition experiment.

N addition increased the production, mortality, and turnover of AFRs but not TFRs. High rates of N persistently inhibited AFR decomposition but affected TFR decomposition differentially at the early (no effect) and late (negative effect) stages. The increased production of AFRs was driven by N‐induced decrease in foliar and soil phosphorus (P) concentrations. The decreased decomposition of AFRs might be due to the increased acid‐unhydrolyzable residues in decomposing roots.

AFRs are the resource‐acquiring module, the increased carbon allocation to AFRs may represent a P‐acquiring strategy when N no longer limits growth of P. elliottii. Our results suggest that AFRs and TFRs respond differently to N deposition, both in terms of production, mortality, and turnover and in terms of decomposition.

AbstractAspartic acid 103 (D103) of sensory rhodopsin II from Halobacterium salinarum (HsSRII, or also called phoborhodopsin) corresponds to D115 of bacteriorhodopsin (BR). This amino acid residue is functionally important in BR. This work reveals that a substitution of D103 with asparagine (D103N) or glutamic acid (D103E) can cause large changes in HsSRII photocycle. These changes include (1) shortened lifetime of the M intermediate in the following order: the wild‐type > D103N > D103E; (2) altered decay pathway of a 13‐cis O‐like species. The 13‐cis O‐like species, tentatively named Px, was detected in HsSRII photocycle. Px appeared to undergo branched reactions at 0°C, leading to a recovery of the unphotolyzed state and formation of a metastable intermediate, named P370, that slowly decayed to the unphotolyzed state at room temperature. In wild‐type HsSRII at 0°C, Px mainly decayed to the unphotolyzed state, and the decay reaction toward P370 was negligible. In mutant D103E at 0°C, Px decayed to P370, while the recovery of the unphotolyzed state became unobservable. In mutant D103N, the two reactions proceeded at comparable rates. Thus, D103 of HsSRII may play an important role in regulation of the photocycle of HsSRII.

Published: March 2018

SummaryLeishmania enter macrophages through receptor‐mediated phagocytosis and survive the harsh environment of a phagolysosome. Here, we investigated the interaction between mannose receptor (MR), Toll‐like receptor 2 (TLR2), and Leishmania, and the subsequent impact on phagosome maturation. Leishmania parasites are able to delay phagosome maturation, not reaching full maturation until 5 hours post‐engulfment. Here, maturation of Leishmania major‐ and Leishmania donovani‐containing phagosomes proceeded as expected in the WT macrophages becoming LAMP1 positive by 6 hours. Interestingly, MR−/− macrophages become LAMP1 positive by ~2 hours and ~4 hours post‐infection Leishmania‐containing phagosomes lost LAMP1 expression and gained the early marker EEA1. LAMP1 expression was again observed by 6 hours. Leishmania LPG was essential for the delay in both WT and MR−/− macrophages but was not essential for the early maturation (2 hours) observed in MR−/− macrophages. Serum opsonization of Leishmania prior to infection induced identical phagosome maturation patterns in WT and MR−/− macrophages. In the absence of MyD88 or TLR2 on macrophages, Leishmania phagosomes matured significantly faster, becoming LAMP1 positive by ~1‐2 hours. These studies add to the knowledge that phagosome maturation is influenced by multiple receptor‐ligand interactions and signalling pathways
Suicide Among Health Care Practitioners and Technicians in Colorado: An Epidemiological Study
Authors: Mintz Sasha , Jamison Ethan , Bol Kirk 
Published: March 2018

Suicide is a public health concern with risks that vary between occupation groups. Many suicide victims with a health care occupation die by poisoning, but few studies have epidemiologically studied this association. The objective of this study was to quantify the increased risk of suicide death by poisoning among health care professionals in Colorado. Eleven years (2004–2014, N = 8,753) of suicide deaths in Colorado were compiled from the Colorado Violent Death Reporting System. A retrospective cohort study using multivariate logistic regression was conducted to examine the risk associated with having a health care occupation and eventual suicide death by poisoning, compared independently to firearm and hanging methods. Suicide victims with a health care occupation were more likely to die by poisoning rather than by hanging (RR 1.54, 95% CI: 1.41–1.68) or firearm (RR 1.79, 95% CI: 1.60–2.01), when compared to suicide victims without a health care occupation. The association between health care occupation and suicide method was significantly (p = .032) modified by gender. The results show that health care workers who die by suicide have an increased risk of eventual suicide death by poisoning rather than by firearm or hanging. These results can be used to inform tailored suicide prevention efforts in health care professionals.

AbstractBackgroundOne major sequelae of acne is atrophic scarring, yet objective tools to assess scars are lacking. Neither depth nor volume of atrophic scars is readily evaluable clinically and standard 2D photography is significantly affected by lighting and shadows. The aim of our study was to define and evaluate parameters of 3D imaging that can be used to assess severity of atrophic acne scarring.MethodsSingle center study of 31 patients with acne scarring. A target area of 3 × 3 cm was defined on the face. The global severity of atrophic acne scarring in the target area was evaluated by 5 dermatologists and scars were counted and categorized by size (scars < 2 mm, 2‐4 mm, and > 4 mm in diameter). Three dimensional images of the target area were acquired with the LifeViz Micro® system and analysis was performed using MountainsMaps® software. An algorithm was developed to quantify the scar volume loss: shape removal step, with an order 5 polynomial, and to calculate the Valley void volume 80% (Vvv 80%) defined in the ISO‐25178 standard for 3D surface texture.ResultsCorrelation coefficient of the Vvv parameter to mean global severity at the target area rating was 0.77. The volume of scars evaluated with the Vvv parameter was mainly impacted by scars > 2 mm. The evaluations demonstrated good repeatability (with an intra‐class correlation coefficient ICC = 0.98).ConclusionsWe demonstrate convergent validation to clinical assessment and repeatability of 3D skin imaging in atrophic acne scarring. Image analysis is straightforward and can be integrated into an automated workflow.

AbstractOrgan Procurement & Transplantation Network policy requires post‐transplant screening of recipients of organs from donors at increased risk for transmission of HIV, hepatitis B virus, and hepatitis C virus. Available data suggest that follow‐up testing of recipients is not routinely conducted. Data on increased risk donors and recipients of their organs from 2008 to 2012 were retrospectively collected from 6 transplant centers after IRB approval. Descriptive statistics were performed. About 363 (60%) recipients were screened for transmission of HIV, HBV, and/or HCV at some time point; 257 (70.8%) within 90 days of transplant. The type of test used to screen for infection was variable with many recipients (25%‐43%) screened with serology alone. Our results reveal that post‐transplant screening for HIV, HBV, and HCV in recipients of increased risk donor organs did not universally occur and testing methods were variable.

AbstractBackgroundConjugated pneumococcal vaccine is recommended for kidney transplant recipients, however, their immunogenicity and potential to trigger allograft rejection though generation of de novo anti‐human leukocyte antigen antibodies has not been well studied.MethodsClinically stable kidney transplant recipients participated in a prospective cohort study and received a single dose of 13‐valent conjugate pneumococcal vaccine. Anti‐pneumococcal IgG was measured for the 13 vaccine serotypes pre and post vaccination and functional anti‐pneumococcal IgG for 4 serotypes post vaccination. Anti‐human leukocyte antigen antibodies antibodies were measured before and after vaccination. Kidney transplant recipients were followed clinically for 12 months for episodes of allograft rejection or invasive pneumococcal disease.ResultsForty‐five kidney transplant recipients participated. Median days between pre and post vaccination serology was 27 (range 21‐59). Post vaccination, there was a median 1.1 to 1.7‐fold increase in anti‐pneumococcal IgG antibody concentrations for all 13 serotypes. Kidney transplant recipients displayed a functional antibody titer ≥1:8 for a median of 3 of the 4 serotypes. Post vaccination, there were no de novo anti‐human leukocyte antigen antibodies, no episodes of biopsy proven rejection or invasive pneumococcal disease.ConclusionA single dose of 13‐valent conjugate pneumococcal vaccine elicits increased titers and breadth of functional anti‐pneumococcal antibodies in kidney transplant recipients without stimulating rejection or donor‐specific antibodies.

AbstractA 61‐year‐old Caucasian man presented with papules on his left forearm and hand three months after liver transplantation: images from physical exam, pathology, and microbiology are presented. Skin biopsy confirmed the presence of fungal elements within the hair shaft, which is consistent with Majocchi granuloma, also known as nodular granulomatous perifolliculitis. A combination of fungal culture, microscopic morphology, and gene sequencing was used to identify the causative organism. The patient recovered with appropriate systemic antifungal therapy.

AbstractBackgroundSolid organ transplant recipients are at increased risk for reactivation of herpes zoster, or shingles, and have a higher frequency of serious complications including post‐herpetic neuralgia. A live, attenuated shingles vaccine is effective and approved for individuals 50 years and older. The vaccine is contraindicated following transplantation, but may be used in patients with renal failure. Utilization of the vaccine has been poor in patients with end‐stage renal disease, including those awaiting transplant, owing to concerns for safety, efficacy, and potential sensitization prior to transplant.MethodsWe conducted a phase I, randomized, placebo‐controlled study of the safety and immunogenicity of live, attenuated Oka strain shingles vaccine in subjects prior to or awaiting renal transplant at 3 US centers. Subjects received vaccine a minimum of 4 weeks prior to transplant.ResultsThe vaccine was safe and well‐tolerated. There were no cases of herpes zoster or rash illness. There was no change in donor‐specific antibody or calculated panel reactive antibody after vaccination during the follow‐up period. There were no rejection episodes. There was a significant 2.1‐fold rise in geometric mean titer of anti‐VZV antibody at 5 weeks post‐vaccine.ConclusionsThe data suggest that the shingles vaccine is safe in subjects with ESRD awaiting transplant. Antibody responses were similar to those seen previously in adults >50 years of age and are consistent with a protective response.
Progressive multifocal leukoencephalopathy after allogeneic stem cell transplantation: Case report and review of the literature

Published: March 2018

AbstractProgressive multifocal leukoencephalopathy (PML) is a rare, yet typically fatal complication of allogeneic stem cell transplantation. It is caused by reactivation of the John Cunningham (JC) virus in an immunocompromised host. This report describes an unfortunate case of PML in a recipient of an allogeneic stem cell transplant for acute myelogenous leukemia. The JC virus was undetectable in the patient's cerebrospinal fluid by polymerase chain reaction (PCR); however, a positive diagnosis was made after a brain biopsy. This and other published cases demonstrate that recipients of allogeneic stem cells can develop PML. Moreover, early diagnosis of the disease is often difficult and, as demonstrated in this case, screening with PCR does not appear to have strong diagnostic significance. With no effective treatment presently available, restoration of immune function is the only intervention that can affect prognosis. Further prospective studies are needed to understand the pathophysiology and treatment of this disease.
Changes in chromatin accessibility between Arabidopsis stem cells and mesophyll cells illuminate cell type‐specific transcription factor networks

Published: March 2018

SummaryCell differentiation is driven by changes in the activity of transcription factors (TFs) and subsequent alterations in transcription. To study this process, differences in TF binding between cell types can be deduced by probing chromatin accessibility. We used cell type‐specific nuclear purification followed by the assay for transposase‐accessible chromatin (ATAC‐seq) to delineate differences in chromatin accessibility and TF regulatory networks between stem cells of the shoot apical meristem (SAM) and differentiated leaf mesophyll cells in Arabidopsis thaliana. Chromatin accessibility profiles of SAM stem cells and leaf mesophyll cells were very similar at a qualitative level, yet thousands of regions having quantitatively different chromatin accessibility were also identified. Analysis of the genomic regions preferentially accessible in each cell type identified hundreds of overrepresented TF‐binding motifs, highlighting sets of TFs that are probably important for each cell type. Within these sets, we found evidence for extensive co‐regulation of target genes by multiple TFs that are preferentially expressed in each cell type. Interestingly, the TFs within each of these cell type‐enriched sets also showed evidence of extensively co‐regulating each other. We further found that preferentially accessible chromatin regions in mesophyll cells tended to also be substantially accessible in the stem cells, whereas the converse was not true. This observation suggests that the generally higher accessibility of regulatory elements in stem cells might contribute to their developmental plasticity. This work demonstrates the utility of cell type‐specific chromatin accessibility profiling for the rapid development of testable models of regulatory control differences between cell types.

Published: March 2018

The aim of this study is to investigate the effect of intensive basketball competitions (10 official basketball games in 12 days intensive competition period) on blood parameters of basketball players. Blood samples were taken from the basketball players of the university team. The players were training regularly and they had no regular health problems. The average age of the players was 22,80 ± 3,20 years and the average height was 185,83 ± 7,57 cm. This study was performed on 10 volunteer basketball players. Blood samples were taken before (24 hours), after (24 hours) and during the intensive competitions. Descriptive statistics (mean and standard deviation) were applied to the data, Wilcoxon two realized sample test was used to compare the values before and after the competition period. When comparing the blood values before and after the competition period, there was significant increase in prevalence of Fe, albumin, AST, ALT, LDL, HDL, MCH, MCHC and the values of UIBC, creatinine, HCT and MPV were significantly low before the competition; (P <0.05).The findings show that the physiological characteristics of basketball players are influenced by intensive competitions. In the literature, the physiological effects of regular and single-session exercises have been investigated in many studies. However, the data about the physiological effects of intensive competition periods are rather limited. A better understanding of these influences will guide the event organizers and coaches to plan the competitions and it will facilitate the preparation of the sportsmen for this intensive competition periods.

ABSTRACT

The genomes of many strains of
Escherichia coli
have been sequenced, as this organism is a classic model bacterium. Here, we report the genome sequence of
Escherichia coli
DH5α, which is resistant to a T4 bacteriophage (CCTCC AB 2015375), while its other homologous
E. coli
strains, such as
E. coli
BL21, DH10B, and MG1655, are not resistant to phage invasions. Thus, understanding of the genome of the DH5α strain, along with comparative analysis of its genome sequence along with other sequences of
E. coli
strains, may help to reveal the bacteriophage resistance mechanism of
E. coli
