Time-dependent Changes in Shrimp Armor and Escape Kinematics under Ocean Acidification and Warming.

Pandalid shrimp use morphological and behavioral defenses against their numerous fish and invertebrate predators. Their rapid tail-flip escape and rigid exoskeleton armor may be sensitive to changes in ocean temperature and carbon chemistry in ways that alter their efficacy and impact mortality. Here we tested the hypothesis that ocean warming and acidification conditions affect the antipredator defenses of Pandalus gurneyi.

Plague mitigation for prairie dog and black-footed ferret conservation: Degree and duration of flea control with 0.005% fipronil grain bait.

Sylvatic plague, a primarily flea-borne zoonosis, is a significant threat to prairie dogs ( spp., PDs) and their specialized predators, endangered black-footed ferrets (, BFFs). Host-fed fipronil baits have proven effective in controlling fleas on PDs for the purposes of plague mitigation and BFF conservation.

Infantile Hemangioma: A Common Lesion in a Vulnerable Population.

Infantile hemangioma (IH) is important to all dentists, particularly dentists providing services to pediatric populations, because significant morbidity and mortality can occur from vascular lesions in children. Specialists of the oral cavity have the responsibility to identify patients with IH, a lesion that could be potentially life threatening. We present a case of IH and will provide a narrative review of the most recent literature.

Assembling a safe and effective toolbox for integrated flea control and plague mitigation: Fipronil experiments with prairie dogs.

Background: Plague, a widely distributed zoonotic disease of mammalian hosts and flea vectors, poses a significant risk to ecosystems throughout much of Earth. Conservation biologists use insecticides for flea control and plague mitigation. Here, we evaluate the use of an insecticide grain bait, laced with 0.

Immune-Related Genomic Schizophrenic Subtyping Identified in DLPFC Transcriptome.

Well-documented evidence of the physiologic, genetic, and behavioral heterogeneity of schizophrenia suggests that diagnostic subtyping may clarify the underlying pathobiology of the disorder. Recent studies have demonstrated that increased inflammation may be a prominent feature of a subset of schizophrenics. However, these findings are inconsistent, possibly due to evaluating schizophrenics as a single group.

Selection of mucocele management technique: considerations in pediatric patients.

The objectives of this article are to describe the surgical excision of an oral mucocele in a 9-year-old boy and to examine the literature on mucocele management approaches, highlighting their advantages and disadvantages in terms of a patient's ability to cooperate in the dental chair. In the present case, a 9-year-old boy who was known to be a cooperative patient underwent conventional surgical excision and tolerated the procedure well. A review of the literature from 2010 to 2018 revealed 20 relevant studies outlining a variety of approaches to mucocele management, including surgical excision, intralesional corticosteroid injection, laser removal, micromarsupialization, cryosurgery, and withholding treatment for cases in which a lesion is small and allowed to spontaneously regress.

In vivo evaluation of temperature-responsive antimicrobial-loaded PNIPAAm hydrogels for prevention of surgical site infection.

Surgical site infections (SSIs) are a persistent clinical challenge. Local antimicrobial delivery may reduce the risk of SSI by increasing drug concentrations and distribution in vulnerable surgical sites compared to what is achieved using systemic antimicrobial prophylaxis alone. In this work, we describe a comprehensive in vivo evaluation of the safety and efficacy of poly(N-isopropylacrylamide-co-dimethylbutyrolactone acrylamide-co-Jeffamine M-1000 acrylamide) [PNDJ], an injectable temperature-responsive hydrogel carrier for antimicrobial delivery in surgical sites.

Incidence and Treatment Efficacy of Trigger Finger in the Breast Cancer Population on Aromatase Inhibitors.

Background: Trigger finger is a common hand complaint of the general population. Limited literature exists implicating a low-estrogen state in patients on aromatase inhibitor (AI) therapy for breast cancer who develop trigger finger. The authors' objective was to determine the incidence and treatment outcomes of this population.

Fipronil Pellets Reduce Flea Abundance on Black-Tailed Prairie Dogs: Potential Tool for Plague Management and Black-Footed Ferret Conservation.

In western North America, sylvatic plague (a flea-borne disease) poses a significant risk to endangered black-footed ferrets (Mustela nigripes) and their primary prey, prairie dogs (Cynomys spp.). Pulicides (flea-killing agents) can be used to suppress fleas and thereby manage plague.

Managing plague on prairie dog colonies: insecticides as ectoparasiticides.

Human health practitioners and wildlife biologists use insecticides to manage plague by suppressing fleas (Siphonaptera), but insecticides can also kill other ectoparasites. We investigated effects of deltamethrin and fipronil on ectoparasites from black-tailed prairie dogs (Cynomys ludovicianus, BTPDs). In late July, 2018, we treated three sites with 0.

Vascularized ameloblastoma: A case report and clinicopathologic review of 18 cases from the literature.

The notable features of ameloblastoma do not typically include prominent vascularity. However, on rare occasions, vascular ameloblastoma has been described under a variety of names. We present a case of vascularized ameloblastoma that had a bloody return on fine-needle aspiration.

Aurora A inhibition limits centrosome clustering and promotes mitotic catastrophe in cells with supernumerary centrosomes.

The presence of supernumerary centrosomes is prevalent in cancer, where they promote the formation of transient multipolar mitotic spindles. Active clustering of supernumerary centrosomes enables the formation of a functional bipolar spindle that is competent to complete a bipolar division. Disruption of spindle pole clustering in cancer cells promotes multipolar division and generation of non-proliferative daughter cells with compromised viability.

Temperature-responsive PNDJ hydrogels provide high and sustained antimicrobial concentrations in surgical sites.

Local antimicrobial delivery is a promising strategy for improving treatment of deep surgical site infections (SSIs) by eradicating bacteria that remain in the wound or around its margins after surgical debridement. Eradication of biofilm bacteria can require sustained exposure to high antimicrobial concentrations (we estimate 100-1000 μg/mL sustained for 24 h) which are far in excess of what can be provided by systemic administration. We have previously reported the development of temperature-responsive hydrogels based on poly(N-isopropylacrylamide-co-dimethylbutyrolactone acrylate-co-Jeffamine M-1000 acrylamide) (PNDJ) that provide sustained antimicrobial release in vitro and are effective in treating a rabbit model of osteomyelitis when instilled after surgical debridement.

Evaluation of Five Pulicides to Suppress Fleas on Black-Tailed Prairie Dogs: Encouraging Long-Term Results with Systemic 0.005% Fipronil.

Plague, a flea-borne disease, hampers efforts to restore populations of black-footed ferrets (), which occupy colonies of prairie dogs ( spp.) in North America. Plague is managed by infusing prairie dog burrows with DeltaDust 0.

Enhanced Rotator-Cuff Repair Using Platelet-Rich Plasma Adsorbed on Branched Poly(ester urea)s.

Platelet-rich plasma (PRP) is a clinically relevant source of growth factors used commonly by surgeons. The clinical efficacy of PRP use as reported in the literature is widely variable which is likely attributed to poorly defined retention time of PRP at the repair site. To overcome this limitation, branched poly(ester urea) (PEU) nanofibers were used to adsorb and retain PRP at the implant site in an acute rotator-cuff tear model in rats.

RESISTANCE TO DELTAMETHRIN IN PRAIRIE DOG ( CYNOMYS LUDOVICIANUS) FLEAS IN THE FIELD AND IN THE LABORATORY.

Sylvatic plague poses a substantial risk to black-tailed prairie dogs ( Cynomys ludovicianus) and their obligate predator, the black-footed ferret ( Mustela nigripes). The effects of plague on prairie dogs and ferrets are mitigated using a deltamethrin pulicide dust that reduces the spread of plague by killing fleas, the vector for the plague bacterium. In portions of Conata Basin, Buffalo Gap National Grassland, and Badlands National Park, South Dakota, US, 0.

The association between continual, year-round hunting and bellowing rate of bison bulls during the rut.

The impact of hunting (selective harvest, trophy hunting) on the demography of mammals is well documented. However, despite continual year-round hunting of bison in some populations, little is known about how the behavior of survivors may be altered. Therefore, in this initial study, we used focal-animal observations in adjacent populations of continually hunted and protected Plains bison () in western South Dakota, to examine the potential impact of hunting on bellowing rate-an important behavior that serves to intimidate rival bulls and potentially influences mate choice by females.

Optical High Content Nanoscopy of Epigenetic Marks Decodes Phenotypic Divergence in Stem Cells.

While distinct stem cell phenotypes follow global changes in chromatin marks, single-cell chromatin technologies are unable to resolve or predict stem cell fates. We propose the first such use of optical high content nanoscopy of histone epigenetic marks (epi-marks) in stem cells to classify emergent cell states. By combining nanoscopy with epi-mark textural image informatics, we developed a novel approach, termed EDICTS (Epi-mark Descriptor Imaging of Cell Transitional States), to discern chromatin organizational changes, demarcate lineage gradations across a range of stem cell types and robustly track lineage restriction kinetics.

Adhesion of Blood Plasma Proteins and Platelet-rich Plasma on l-Valine-Based Poly(ester urea).

The competitive absorption of blood plasma components including fibrinogen (FG), bovine serum albumin (BSA), and platelet-rich plasma (PRP) on l-valine-based poly(ester urea) (PEU) surfaces were investigated. Using four different PEU polymers, possessing compositionally dependent trends in thermal, mechanical, and critical surface tension measurements, water uptake studies were carried out to determine in vitro behavior of the materials. Quartz crystal microbalance (QCM) measurements were used to quantify the adsorption characteristics of PRP onto PEU thin films by coating the surfaces initially with FG or BSA.

Lessons from Prenatal Care Provider-Based Recruitment into the National Children's Study.

In response to recruitment difficulties experienced by the National Children's Study, alternatives to the door-to-door recruitment method were pilot tested. This report describes outcomes, successes, and challenges of recruiting women through prenatal care providers in Benton County, Arkansas, USA. Eligible women residing in 14 randomly selected geographic segments were recruited.

l-Leucine-Based Poly(ester urea)s for Vascular Tissue Engineering.

Poly(ester urea)s (PEUs) derived from α-amino acids are promising for vascular tissue engineering applications. The objective of this work was to synthesize and characterize l-leucine-based PEUs and evaluate their suitability for vascular tissue engineering. Four different PEUs were prepared from di--toluenesulfonic acid salts of bis-l-leucine esters and triphosgene using interfacial condensation polymerizations.

Adhesion properties of catechol-based biodegradable amino acid-based poly(ester urea) copolymers inspired from mussel proteins.

Amino acid-based poly(ester urea) (PEU) copolymers functionalized with pendant catechol groups that address the need for strongly adhesive yet degradable biomaterials have been developed. Lap-shear tests with aluminum adherends demonstrated that these polymers have lap-shear adhesion strengths near 1 MPa. An increase in lap-shear adhesive strength to 2.
