Bacterial synergies amplify nitrogenase activity in diverse systems.

Endophytes are microbes living within plant tissue, with some having the capacity to fix atmospheric nitrogen in both a free-living state and within their plant host. They are part of a diverse microbial community whose interactions sometimes result in a more productive symbiosis with the host plant. Here, we report the co-isolation of diazotrophic endophytes with synergistic partners sourced from two separate nutrient-limited sites.

Outcomes in Minor Salivary Gland Tumors-A 20+ Year Tertiary-Care Center Experience.

Objective: Minor salivary gland carcinomas are challenging to study due to their rarity and heterogeneity. We aim to further characterize clinical characteristics, treatment, and outcomes over 20 years within a single institution.

Study Design: Retrospective chart review was conducted on 210 patients who received primary treatment for minor salivary gland malignancy from 2000 to 2022.

Examining timing of periorbital interventions in patients with upper division facial paralysis.

Background: Facial paralysis is a life-altering condition that may arise from various etiologies, ranging from trauma to malignancy. Permanent facial paralysis may occur secondary to facial nerve sacrifice or irreversible damage to the nerve. In these particularly devastating cases, protection and maintaining function of the eye is paramount.

A Reproducible Peritonsillar Abscess Incision and Drainage Model for Junior Trainees.

Objectives: To describe the design and construction of a reproducible, low-cost, peritonsillar abscess (PTA) incision and drainage simulator and assess its impact on trainees' confidence.

Methods: The 2-part simulator we developed consisted of a manikin head with a fixed, partially open mouth and a modular PTA mold. The mold is created by injecting a lotion and water mixture into plastic bubbles, followed by silicone solidification.

Curtobacterium sp. strain WW7 is a Gram-positive, non-motile, orange rod-shaped bacterium isolated from branches of wild willow (Salix sitchensis) trees. The WW7 strain has optimum growth in the temperature range between 25 and 30 °C, a pH range of 6-7.

Bridging Time-series Image Phenotyping and Functional-Structural Plant Modeling to Predict Adventitious Root System Architecture.

Root system architecture (RSA) is an important measure of how plants navigate and interact with the soil environment. However, current methods in studying RSA must make tradeoffs between precision of data and proximity to natural conditions, with root growth in germination papers providing accessibility and high data resolution. Functional-structural plant models (FSPMs) can overcome this tradeoff, though parameterization and evaluation of FSPMs are traditionally based in manual measurements and visual comparison.

Effect of Arsenic on EPS Synthesis, Biofilm Formation, and Plant Growth-Promoting Abilities of the Endophytes PD9R and PD12R.

Phytoremediation, a cost-effective, eco-friendly alternative to conventional remediation, could expand efforts to remediate arsenic-contaminated soils. As with other pollutants, the plant microbiome may improve phytoremediation outcomes for arsenic-contaminated sites. We used and methods to compare the arsenic resistance mechanisms, synthesis of extracellular polymeric substances (EPS), biofilm formation, and plant growth-promoting abilities of the endophytes sp.

Potential Biocontrol Activities of Endophytes against Several Plant Pathogens Using Different Inhibitory Mechanisms.

The plant microbiome can be used to bolster plant defense against abiotic and biotic stresses. Some strains of endophytes, the microorganisms within plants, can directly inhibit the growth of plant fungal pathogens. A previously isolated endophyte from wild (poplar), WPB of the species , had robust in vitro antifungal activity against pathogen strains that are highly virulent and of concern to Pacific Northwest agriculture: AG-8, 70110023, and var.

Feasibility of gabapentin as an intervention for neurorecovery after an acute spinal cord injury: Protocol.

Introduction: This protocol is describing the first ever prospective, mock-efficacy, dose exploration trial design testing the feasibility of administering gabapentin in the acute setting as an intervention for neurorecovery. Gabapentin is an FDA-approved medication for treating seizures and postherpetic neuralgia and is used broadly off-label for neuropathic pain management for many conditions, including spinal cord injury. Emerging data suggests that when given early after spinal cord injury onset and in low-medium doses, gabapentin may have properties that promote recovery of neurological function.

Neuromechanical Integration of Pelvic-Thoracic Rotation among Youth Baseball Throwers.

The kinetic sequencing involved in the overhead throw anticipates an orchestration of body movement in which the more proximal segments of the body initiate movement prior to the more distal segment. This investigation explored neuromuscular and kinematic characteristics associated with one aspect of this kinetic sequencing, pelvic-to-thoracic rotation. Neuromuscular activation was recorded using surface electromyography and kinematic data was acquired using 3D videography.

The Dorsal Ligament Complex: A Cadaveric, Histology, and Imaging Study.

Purpose: The distinction between the dorsal intercarpal (DIC) and dorsal scaphotriquetral (DST) ligaments is imprecise and unclear in the literature. The purpose of our cadaveric study was to define the origins, insertions, and anatomic relationships of the dorsal wrist ligaments and relate these anatomic findings to magnetic resonance imaging (MRI) scans and histology.

Methods: The study included 17 unmatched fresh-frozen cadaveric specimens (7 male and 10 female), with a mean age of 67.

Endophyte-Promoted Phosphorus Solubilization in .

Phosphorus is one of the essential nutrients for plant growth, but it may be relatively unavailable to plants because of its chemistry. In soil, the majority of phosphorus is present in the form of a phosphate, usually as metal complexes making it bound to minerals or organic matter. Therefore, inorganic phosphate solubilization is an important process of plant growth promotion by plant associated bacteria and fungi.

Broadening Our Bandwidth: A Multiple Case Report of Expanded Use of Telehealth Technology to Perform Wound Consultations During the COVID-19 Pandemic.

Background: Managing patients during the coronavirus disease-2019 (COVID-19) pandemic, and the associated severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) in particular, required the nimble responsiveness for which WOC nurses are known. Problem-solving skills were needed to continue the level of WOC nursing services expected by patients, families, and professional colleagues, while reducing the hours we were physically present at our clinical facility. In order to respond to these demands, our team realized it must create an innovative approach to provide efficient, cost-effective consultations during this global crisis.

Carbonyl iron and iron dextran therapies cause adverse effects on bone health in juveniles with chronic kidney disease.

Anemia is a frequent complication of chronic kidney disease (CKD), related in part to the disruption of iron metabolism. Iron therapy is very common in children with CKD and excess iron has been shown to induce bone loss in non-CKD settings, but the impact of iron on bone health in CKD remains poorly understood. Here, we evaluated the effect of oral and parenteral iron therapy on bone transcriptome, bone histology and morphometry in two mouse models of juvenile CKD (adenine-induced and 5/6-nephrectomy).

Endophytes Increased Fruit Quality with Higher Soluble Sugar Production in Honeycrisp Apple ().

Endophytes are fungi, bacteria, or yeast symbionts that live in the intercellular spaces or vascular tissues of host plants. Investigations indicate that endophytes isolated from the Salicaceae family ( and ) hosts provide several benefits that promote plant growth, including but not limited to di-nitrogen fixation, plant hormone production, nutrient acquisition, stress tolerance, and defense against phytopathogens. In exchange, the microorganisms receive domicile and photosynthates.

Influences of Climate on Phyllosphere Endophytic Bacterial Communities of Wild Poplar.

Plant-associated microbial communities play a central role in the plant response to biotic and abiotic stimuli, improving plant fitness under challenging growing conditions. Many studies have focused on the characterization of changes in abundance and composition of root-associated microbial communities as a consequence of the plant response to abiotic factors such as altered soil nutrients and drought. However, changes in composition in response to abiotic factors are still poorly understood concerning the endophytic community associated to the phyllosphere, the above-ground plant tissues.

Endophytes alleviate the elevated CO2-dependent decrease in photosynthesis in rice, particularly under nitrogen limitation.

The positive effects of high atmospheric CO2 concentrations [CO2] decrease over time in most C3 plants because of down-regulation of photosynthesis. A notable exception to this trend is plants hosting N-fixing bacteria. The decrease in photosynthetic capacity associated with an extended exposure to high [CO2] was therefore studied in non-nodulating rice that can establish endophytic interactions.

Understanding Complex Roles of Family for Latina Health: Evaluating Family Obligation Stress.

We developed a measure of family obligation stress and compared its relationship to health and unmet health care needs relative to social support among a sample of US-based Latinas. Data come from a randomized controlled trial within 4 clinics to increase mammography among Latinas (n = 539). The 1-factor measure had acceptable reliability and construct validity.
