Antagonistic biotic interactions mitigate the positive effects of warming on wood decomposition.

Global change drivers such as habitat fragmentation, species invasion, and climate warming can act synergistically upon native systems; however, global change drivers can be neutralized if they induce antagonistic interactions in ecological communities. Deadwood comprises a considerable portion of forest carbon, and it functions as refuge, nesting habitat and nutrient source for plant, animal and microbial communities. We predicted that thermophilic termites would increase wood decomposition with experimental warming and in forest edge habitat.

Small-angle scattering of complex fluids in flow.

Complex fluids encompass a significant proportion of the materials that we use today from feedstocks such as cellulose fibre dispersions, materials undergoing processing or formulation, through to consumer end products such as shampoo. Such systems exhibit intricate behaviour due to their composition and microstructure, particularly when analysing their texture and response to flow (rheology). In particular, these fluids when flowing may undergo transitions in their nano- to microstructure, potentially aligning with flow fields, breaking and reassembling or reforming, or entirely changing phase.

Toxin-Induced Liver Injury and Extracorporeal Treatment of Liver Failure.

Poisoning with a large variety of drugs and naturally occurring toxins may result in acute liver injury and failure. Drug-induced liver injury is a major cause of liver failure nationwide, and it is likely that nephrologists will be involved in treating patients with these conditions. A number of xenobiotics resulting in liver toxicity may cause acute kidney injury or other organ injury as well.

Effect of Selective Laser Trabeculoplasty on the Fellow Eye.

Aim: Determine if selective laser trabeculoplasty (SLT) affects the fellow eye's intraocular pressure (IOP).

Materials And Methods: A retrospective review of 76 pairs of eyes from 76 adult glaucoma patients who underwent SLT in one eye with at least 2 months between treatments were evaluated for IOP and medication reduction in the untreated fellow eye. Success was defined as ≥20% IOP reduction or ≥1 medication reduction without any additional IOP lowering procedures or medication.

Sulcus Tube Internal Needle Guidewire Technique for Glaucoma Drainage Device Placement: Improving Surgical Ease and Precision.

Introduction: Despite the rise of micro-invasive glaucoma surgery (MIGS), glaucoma drainage device implantation continues to be a mainstay among glaucoma surgical treatment options. Anterior chamber tube placement, while effective in reducing intraocular pressure (IOP), poses corneal endothelial risks. Ciliary sulcus tube placement shows promise in reduced corneal endothelial cell loss, but proper sulcus placement can be challenging.

Stratification and film ripping induced by structural forces in granular micellar thin films.

Hypothesis: Interactions across incredibly thin layers of fluids, known as thin films, underpin many important processes involving colloids, such as wetting-dewetting phenomena. Often in these systems, thin films are composed of complex fluids that contain dispersed components, such as spherical micelles, giving rise to oscillatory structural forces due to preferential layering under confinement. Modelling of thin film dynamics involving Derjaguin-Landau-Verwey-Overbeek (DLVO) type forces has been widely reported using the Stokes-Reynolds-Young-Laplace (SRYL) model, and we hypothesize that this theory can be extended to a concentrated micellar system by including an oscillatory structural force term in the disjoining pressure.

The Impact of Non-opioid Analgesic Usage on Total Opioid Load During Traumatic Brain Injury Rehabilitation: A Retrospective Study.

Background Patients staying in acute rehabilitation often use large amounts of opioids during their stay. There are a number of reasons for this increased opioid exposure, including but not limited to daily exercises with physical and occupational therapists, increased demand on a healing body, and use of previously atrophying musculature. Some physiatrists have noticed that patients who concurrently are prescribed medications such as Robaxin seem to require fewer opioids during their stay in acute rehabilitation.

Adrenocortical hemorrhage following intravenous tetracosactide in a dog with hypercortisolism.

Objective: To summarize findings from a case of adrenocortical hemorrhage following tetracosactide injection during ACTH stimulation testing for monitoring of trilostane therapy in a dog.

Animal: A 12-year old neutered male dog with adrenal-dependent hypercortisolism.

Clinical Presentation, Progression, And Procedures: 4 hours after ACTH stimulation testing, the patient developed vomiting, lethargy, and abdominal pain.

Pulmonary Tumor Thrombotic Microangiopathy Caused by Esophageal Adenocarcinoma: A Case Report.

Pulmonary tumor thrombotic microangiopathy (PTTM ) is a rare condition of uncertain incidence given its likely underdiagnosis. PTTM has been described most frequently in association with gastric adenocarcinoma, but other primary malignancies have been identified. The prognosis of PTTM is very poor, and patients often die within days or weeks of diagnosis.

Adapting an Objective Structured Clinical Examination (OSCE) on Conducting Difficult Conversations Between Nephrology Fellows and Patients to a Virtual Platform: A Research Letter.

Background: We previously described a nephrology-specific "Breaking Bad News" Objective Structured Clinical Examination (OSCE) assessing nephrology fellow communication and counseling skills in 3 scenarios: kidney replacement therapy (KRT) in kidney failure, urgent KRT in acute kidney injury (AKI), and kidney biopsy (KBx).

Objective: The main objectives of this study is to adapt the OSCE to a virtual platform, simulating nephrology patient telemedicine encounters involving difficult conversations, and to assess fellow and faculty satisfaction with the virtual format.

Design: Description of a formative telemedicine simulation for nephrology fellows.

Mass Poisoning From Ethylene Glycol at a U.S. Military Base.

Ethylene glycol (EG) toxicity is an important cause of toxic alcohol poisoning in the USA with over 5,000 exposures reported annually. While classically characterized by solitary accidental or intentional ingestions, mass toxic alcohol poisoning outbreaks and more rarely collective consumptions (typically of methanol) have been described. We describe an ethylene glycol poisoning from collective ingestion that involved soldiers presenting at William Beaumont Army Medical Center in El Paso, Texas.

Toxic Alcohol Poisoning.

This article reviews the background, metabolism, clinical effects, and treatment of toxic alcohols, specifically ethylene glycol, methanol, diethylene glycol, propylene glycol, and isopropyl alcohol. This article also reviews the importance of an anion gap metabolic acidosis in relation to toxic alcohols and explores both the utility and the limitations of the osmol gap in patient management.

Dung beetle community composition affects dung turnover in subtropical US grasslands.

An important service in many ecosystems is the turnover and degradation of dung deposited by cattle. Dung beetles are the primary group of insects responsible for dung turnover, and factors affecting their abundance and distribution thus impact dung degradation. Lands lost to grazing due to dung buildup and pasture contamination total millions of acres per year in US pastures.

Heads or tails? The synthesis, self-assembly, properties and uses of betaine and betaine-like surfactants.

Betaines are a key class of zwitterionic surfactant that exhibit particularly favorable properties, making them indispensable in modern formulation. Due to their composition, betaines are readily biodegradable, mild on the skin and exhibit some antimicrobial activity. Vital to their function, these surfactants self-assemble into diverse micellar geometries, some of which contribute to increased solution viscosity, and their surface activity results in strong detergency and foaming.

Photothermally responsive Pickering emulsions stabilised by polydopamine nanobowls.

Pickering emulsions with stimuli responsive properties have attracted mounting research attention owing to their potential for on-demand destabilisation of emulsions. However, a combination of biocompatibility and long-term stability are essential to efficiently apply such systems in biomedical applications, and this remains a significant challenge. To address current limitations, here we report the formation of photothermally responsive oil-in-water (o/w) Pickering emulsions fabricated using biocompatible stabilisers and showing prolonged stability.

analysis of n-acetylcysteine (NAC) interference with the international normalized ratio (INR).

Background: Previous literature suggests a laboratory interference of n-acetylcysteine (NAC) with prothrombin time (PT) and the international normalized ratio (INR). Early publications focused on this interaction in the setting of an acetaminophen overdose and evaluated the INR of patients receiving intravenous NAC. However, there is limited literature describing the concentration-effect relationship of NAC to INR measurement in the absence of acetaminophen-induced hepatotoxicity at therapeutic NAC concentrations.

Participants: 30 eyes of 24 patients undergoing phacoemulsification combined with a KDB with 6 months follow-up and who had previously undergone SLT in the same eye.

Design and synthesis of an azobenzene-betaine surfactant for photo-rheological fluids.

Hypothesis: Morphology of surfactant self-assemblies are governed by the intermolecular interactions and packing constraints of the constituent molecules. Therefore, rational design of surfactant structure should allow targeting of the specific self-assembly modes, such as wormlike micelles (WLMs). By inclusion of an appropriate photo-responsive functionality to a surfactant molecule, light-based control of formulation properties without the need for additives can be achieved.
