In many regions of the world, aeroterrestrial green algae of the Trebouxiophyceae (Chlorophyta) represent very abundant soil microorganisms, and hence their taxonomy is crucial to investigate their physiological performance and ecological importance. Due to a lack in morphological features, taxonomic and phylogenetic studies of Trebouxiophycean algae can be a challenging task. Since chemotaxonomic markers could be a great assistance in this regard, 22 strains of aeroterrestrial Trebouxiophyceae were chemically screened for their polyol-patterns as well as for mycosporine-like amino acids (MAAs) in their aqueous extracts using RP-HPLC and LC-MS...

PURPOSE: Despite the established role of O6-methyl-guanine-DNA methyltransferase (MGMT) as a marker for temozolomide response, consensus of the most reliable method to assess MGMT expression in pituitary adenomas is still missing. Currently, immunohistochemistry (IHC) assessment of formaldehyde fixed tissue samples is most widely used in a semiquantitative description. As formaldehyde fails to completely preserve nucleic acids, RCL2, an alcohol-based formaldehyde-free fixative, has been proposed as a more reliable alternative in terms of cell stability...

OBJECTIVES: The primary objective of this study was to assess pharmacists' authority to provide travel health services in each state and Washington, DC. Secondary objectives were to determine the need for collaborative practice agreements (CPAs), protocols, or prescriptions for this type of pharmacy practice and to identify jurisdictions where pharmacists are able to practice as travel health providers independent of CPAs or individual physician protocols. METHODS: An online survey was developed to assess pharmacists' authority to administer travel immunizations, furnish travel-related medications, and order travel-related laboratory tests...

The present study reports perceptions of first-year undergraduate medical students ( n = 120), regarding modified directed self-learning (DSL) sessions in physiology. Students were provided with prereading assignments (faculty developed PowerPoint slides containing diagrams with incomplete labeling/flowcharts with missing steps) pertaining to the DSL topic 1 wk before the scheduled small-group DSL presentations. During DSL presentation sessions, which were facilitated by teachers, a few students individually presented learning objectives in the specified topic...

Mechanochromic polymers, i.e., polymers sensitive to mechanical impact, promise great potential for applications in damage sensors. In particular, radical-type mechanochromic polymers, which produce colored radical species in response to mechanical stress, may enable not only the visualization of mechanical stress, but also its quantitative evaluation by electron paramagnetic resonance analysis. In this work, a radical-type mechanochromic polymer that exhibits a color change from white to green upon dissociation of a diarylbibenzothiophenonyl moiety at the mid-point of a polystyrene chain is presented, and its mechanochromic behavior examined...

Antiplatelet and anticoagulation therapy after venous stenting is still not standardized, data from randomized-controlled trials are missing. Rare prothrombotic disorders and nonresponsiveness to drugs must be taken into account. This case report demonstrates successful haemostaselogical complication management in recurrent rethromboses due to underlying clopidogrel resistance and low responsiveness to anticoagulation with dabigatran after endovascular stent reconstruction of chronic pelvic and caval vein occlusion in a patient with severe postthrombotic syndrome...

Yongqiang Tang
The controlled imputation method refers to a class of pattern mixture models that have been commonly used as sensitivity analyses of longitudinal clinical trials with nonignorable dropout in recent years. These pattern mixture models assume that participants in the experimental arm after dropout have similar response profiles to the control participants or have worse outcomes than otherwise similar participants who remain on the experimental treatment. In spite of its popularity, the controlled imputation has not been formally developed for longitudinal binary and ordinal outcomes partially due to the lack of a natural multivariate distribution for such endpoints...

Straw colored pleural fluid with raised adenosine deaminase (ADA) levels in young healthy adults usually raises suspicion of tuberculosis, sometimes leading to laxity in carrying thorough physical examination and missing out some important clues with potential disastrous consequences. A 35-year-old male was diagnosed to have left pleural effusion and anti-tubercular treatment was started on the basis of straw colored, lymphocyte-predominant pleural fluid with significantly raised ADA levels. When there was no improvement after 1 month of treatment he was investigated further and found to have a mediastinal mass along with hydro-pneumothorax...

BACKGROUND: A very low birth weight (VLBW) is considered as a significant risk factor for early-onset developmental problems in infants, but is also discussed as a potential risk factor for the development of depressive symptoms in affected parents. METHODS: In this study, the 5-year courses of maternal and paternal depression with VLBW and term born infants (n = 250 families) are modeled and predicted by factors existing at the time of birth. RESULTS: The dyadic trajectories of depression could be best described by five classes (I no depression, II minor maternal depression, III increasing dyadic depression, IV significant maternal depression, V highly depressed mothers)...

Measurement of pupil size (pupillometry) has recently gained renewed interest from psychologists, but there is little agreement on how pupil-size data is best analyzed. Here we focus on one aspect of pupillometric analyses: baseline correction, i.e., analyzing changes in pupil size relative to a baseline period. Baseline correction is useful in experiments that investigate the effect of some experimental manipulation on pupil size. In such experiments, baseline correction improves statistical power by taking into account random fluctuations in pupil size over time...

RATIONALE: Asthma is a chronic disease that affects quality of life, productivity at work and school, healthcare use, and can result in death. Measuring the current economic burden of asthma provides important information on the impact of asthma on society. This information can be used to make informed decisions about allocation of limited public health resources. OBJECTIVES: In this paper, we provide a comprehensive approach to estimate current prevalence, medical costs, cost of absenteeism (missed work and schooldays) and mortality attributable to asthma from a national perspective...

Justin A Harris, Dorothy W S Kwok
During magazine approach conditioning, rats do not discriminate between a conditional stimulus (CS) that is consistently reinforced with food and a CS that is occasionally (partially) reinforced, as long as the CSs have the same overall reinforcement rate per second. This implies that rats are indifferent to the probability of reinforcement per trial. However, in the same rats, the per-trial reinforcement rate will affect subsequent extinction-responding extinguishes more rapidly for a CS that was consistently reinforced than for a partially reinforced CS...

Immunoglobulin G4-related tubulointerstitial nephritis (IgG4-TIN) is a newly recognized clinicopathological entity characterized by a dense interstitial infiltrate of IgG4-positive plasma cells accompanied by fibrosis and obliterative phlebitis causing acute or chronic renal dysfunction amenable to corticosteroid therapy. IgG4-TIN is the dominant manifestation of renal involvement in IgG4-related disease (IgG4-RD) which is a novel, immune-mediated, fibroinflammatory and multiorgan disorder. We describe a case of IgG4-TIN with isolated renal involvement in an elderly male patient with poor response to corticosteroid therapy...

After abandonment of agricultural fields, some grassland plant species colonize these sites with a frequency equivalent to dry grasslands (generalists) while others are missing or underrepresented in abandoned fields (specialists). We aimed to understand the inability of specialists to spread on abandoned fields by exploring whether performance of generalists and specialists depended on soil abiotic and/or biotic legacy. We performed a greenhouse experiment with 12 species, six specialists and six generalists...

INTRODUCTION: In the clinical evaluation of women with pelvic organ prolapse (POP), it is important to evaluate both objective and subjective presentations. The objective evaluation is done by gynecological examination, but the subjective presentation is more complex. The International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) is an important tool for subjective evaluation, and a Danish version was developed. MATERIALS AND METHODS: The English version was translated into Danish in accordance with guidelines...

A collision tumor is defined as two histologically distinct tumor types identified at the same anatomic site. Hematolymphoid proliferative disorders (HLPDs), which coincide with non-hematological neoplasms, can mimic an immune response and can easily be overlooked as an immune reaction to a solid organ neoplasm, especially when low grade. In order to avoid a delay in the diagnosis of a HLPD during the workup for a non-hematological neoplasm, we identified a cohort of 100 cases with a HLPD diagnosis during the initial workup and treatment of a non-hematological neoplasm, or vice versa...

UVA-crosslinking is used for treatment of corneal diseases such as keratoconus in order to stabilize the corneal tissue by crosslinking of the collagen fibers. It has been shown that the crosslinking treatment leads to a stiffening of the central corneal tissue. However, knowledge of lateral extent of the corneal stiffening as well as a systematic study of the mechanical response of human cornea is still missing. In our study we measured the stiffness (elastic modulus) of the anterior surface of healthy and crosslinked human corneas by instrumented indentation using a spherical indenter...

Missing covariate values are prevalent in regression applications. While an array of methods have been developed for estimating parameters in regression models with missing covariate data for a variety of response types, minimal focus has been given to validation of the response model and influence diagnostics. Previous research has mainly focused on estimating residuals for observations with missing covariates using expected values, after which specialized techniques are needed to conduct proper inference...

An important subgroup of people who inject drugs (PWID) receiving opioid agonist therapy (OAT), cannot be treated in the setting of a hepatology center and would not regularly ingest their medication when handed to them for self-administration. Our hypothesis was that chronic hepatitis C in these patients could be ideally managed if modern, interferon-free regimens were administered together with OAT under direct observation of a physician or nurse at a low-threshold facility. In this open-label, non-interventional, proof-of-concept study (ClinicalTrials...
