A 54-year-old male, five months postorthotopic heart transplantation, presented with intermittent fevers, headaches, and “soupy” stools. Prior to presentation, he had low-level cytomegalovirus (CMV) viremia for two straight weeks. Given his immunosuppression, diarrhea, and low-level CMV viremia, he was presumed to have cytomegalovirus and/or C. difficile colitis and treated empirically for both on hospital day one. However, he developed neck pain/stiffness, diaphoresis, and worsening fevers on hospital...

A re-examination of a 300-million-year-old fish, Tanyrhinichthys mcallisteri, revealed that its lifestyle more closely resembled that of the bottom-dwelling sturgeon, rather than the stealthy pike, as was previously believed.

Soybean is widely used as food. Genetic factors, as well as agrotechnical procedures, affect the yield and quality of soybeans. The subject of our research was the synchronization between soil N supply (from both mineralization and fertilization) and crop N demand. The aim of the research was to determine the effect of the cultivar and nitrogen application on the seed yield and mineral content in soybeans. Two non-GMO soybean cultivars (Amandine and Merlin) and four mineral nitrogen fertilizers ((A)...

Urban minority children with asthma are at increased risk for disruptions in sleep and sleep loss due to socio-contextual stressors (poverty, stressors of urban living) and challenges related to following complex asthma treatment regimens.1-2 Atopic dermatitis (AD) is frequently co-morbid in children with asthma and can increase the risk for poor quality sleep, including difficulty falling asleep, nighttime awakenings, time awake after sleep onset, difficulty awakening in the morning, and daytime...

Inhaled corticosteroids (ICS) are used as anti-inflammatory controller therapy given either alone or combination with long acting bronchodilators for persistent asthma . The present COVID-19 pandemic has inevitably focussed attention as to whether ICS might predispose to SARS-CoV-2 infection , especially in older ,male, obese, smokers with comorbidities including chronic lung disease who are prone to more severe COVID-19 infection and worse outcomes. In the later stage of COVID-19 infection there...

The use of telemedicine dates as far back as 50 years ago, when the University of Nebraska used interactive telemedicine to transmit neurologic examinations.1 Since that time, despite advances in available technologies, and proven utility of telemedicine in allergy/immunology (AI),2,3 the uptake of telemedicine by AI physicians remains low.4 With the global spread of novel coronavirus disease 2019 (COVID-19), AI physicians were abruptly forced to change their mode of health care delivery. Given the...

ObjectivesChronic obstructive pulmonary disease and silicosis are associated with exposure to crystalline silica. We determined the exposure to respirable crystalline silica and estimated exposure–response relationships between cumulative exposure and pulmonary function in outdoor rock drillers.Methods136 rock drillers and 48 referents were recruited from three heavy construction companies. 98 air samples were collected by personal sampling for determination of respirable particulate matter and crystalline...

Abstract There are few studies of post-emancipation-period African American agrarian landowners because their numbers were small in contrast to those African Americans who remained landless. Archaeologists’ emphasis on sharecroppers has overlooked the socioeconomic diversity within the African American community and minimized the importance of land ownership to the assertion of black freedom. Using the ceramics recovered from the Ransom and Sarah Williams farmstead, an historical...

Abstract Purpose of Review Antibiotic use is the most important modifiable risk factor for the development of Clostridioides difficile infection (CDI). In addition, up to a quarter of patients treated with standard-of-care antibiotics experience disease recurrence. Until 2016, when bezlotoxumab was approved by the U.S. Food and Drug Administration (FDA), antibiotics were the only medication class approved for use in CDI. A growing...

Abstract Statistical shape analysis of lung is a reliable alternative method for diagnosing pulmonary diseases such as tuberculosis (TB). The 2D contour-based lung shape analysis is investigated and developed using Fourier descriptors (FDs). The proposed 2D lung shape analysis is carried out in threefold: (1) represent the normal and the abnormal (i.e. pulmonary tuberculosis (PTB)) lung shape models using Fourier descriptors modeling (FDM) framework from chest X-ray (CXR) images,...

Frequent fluctuations in sulfate availability rendered syntrophic interactions between the sulfate reducing bacterium Desulfovibrio vulgaris (Dv) and the methanogenic archaeon Methanococcus maripaludis (Mm) unsustainable. By contrast, prolonged laboratory evolution in obligate syntrophy conditions improved the productivity of this community but at the expense of erosion of sulfate respiration (SR). Hence, we sought to understand the evolutionary trajectories that could both increase the productivity...

Pathogens experience selection at multiple scales, given the need to transmit between hosts and replicate within them. This presents the challenge of cross-scale selective conflict when adaptations to one scale compromise fitness at another, such as mutations that improve transmissibility but make individuals less competitive within hosts. Selection operates differently at these scales, with tight transmission bottlenecks subjecting pathogen populations to genetic drift, and large population sizes...

Dietary restriction (DR), limiting calories or specific nutrients, extends lifespan across diverse taxa. This lifespan extension has been explained as diet-mediated changes in the trade-off between lifespan and reproduction, with survival favoured with scarce resources. Another evolutionary hypothesis suggests the selective benefit of the response is the maintenance of reproduction. This hypothesis predicts that lifespan extension is a side effect of benign laboratory conditions, where DR individuals...

In the last 240,000 years, males of the Drosophila simulans species clade have evolved striking differences in the morphology of their epandrial posterior lobes and claspers (surstyli). These changes have most likely been driven by sexual selection and mapping studies indicate a highly polygenic and generally additive genetic basis. However, we have limited understanding of the gene regulatory networks that control the development of genital structures and how they evolved to result in this rapid...

Mitochondria and chloroplasts emerged from primary endosymbiosis. Most proteins of the endosymbiont were subsequently expressed in the nucleo-cytosol of the host and organelle-targeted via the acquisition of N-terminal presequences, whose evolutionary origin remains enigmatic. Using a quantitative assessment of their physico-chemical properties, we show that organelle targeting peptides, which are distinct from signal peptides targeting other subcellular compartments, group with a subset of antimicrobial...

Whether hard sweeps or soft sweeps dominate adaptation has been a matter of much debate. Recently, we developed haplotype homozygosity statistics that (i) can detect both hard and soft sweeps with similar power and (ii) can classify the detected sweeps as hard or soft. The application of our method to population genomic data from a natural population of Drosophila melanogaster (DGRP) allowed us to rediscover three known cases of adaptation at the loci Ace, Cyp6g1, and CHKov1 known to be driven by...

3NT Medical, a company based in Israel, has won FDA clearance to introduce its Colibri Micro ENT Scope in the United States. The single-use device was designed to make surgical procedures a bit easier for otologists. The device features built-in suction for two-handed operation, a 2.2 mm tip, and a light handle that’s easy to work with when inside the ear. Being a disposable device, there’s no reprocessing necessary and it cannot serve as a vector for the transmission of disease...

Since it seems that the virus that causes COVID-19 is going to be with us for a while, face masks will be around as well. As everyone who hasn’t worked in the OR before just noticed, not seeing the entirety of people’s faces influences how we interact with each other. Smiling, for example, completely loses the effect that it is meant to produce in others. And while this is a nuisance and discomfort for most people, those that are deaf or hard of hearing can’t see lip movement and therefore...
