Prophylactic treatment with PEGylated bovine IFNλ3 effectively bridges the gap in vaccine-induced immunity against FMD in cattle.

Foot-and-mouth disease (FMD) is a vesicular disease of cloven-hoofed animals with devastating economic implications. The current FMD vaccine, routinely used in enzootic countries, requires at least 7 days to induce protection. However, FMD vaccination is typically not recommended for use in non-enzootic areas, underscoring the need to develop new fast-acting therapies for FMD control during outbreaks.

Analytical comparability to evaluate impact of manufacturing changes of ARX788, an Anti-HER2 ADC in late-stage clinical development.

ARX788 is an anti-HER2 antibody drug conjugate (ADC) developed using Ambrx proprietary Engineered Precision Biologics technology. The manufacturing process of ARX788 has been optimized during the course of early to late-phase clinical development. A comprehensive evaluation of side-by-side comparability between pre- and post-change process for ARX788 drug substance and drug product from a quality perspective was conducted based on ICH Q5E guidelines consisting of batch release assays, physicochemical and biophysical characterization, biological characterization, and forced degradation studies.

The Dynamics of Interpersonal Relationships: Understanding Power and Control Tactics Among College Students.

Intimate partner violence (IPV) is a significant public health problem among college students and many students have difficulty identifying unhealthy and abusive behaviors. The aims of this mixed methods study are to: (a) create an inclusive tool that illustrates the power and control experiences of a diverse group of young adult college students, (b) ensure a broad scope of tactics are illustrated (related to technology and different types of relationships), and (c) measure the experience of these tactics, including how IPV knowledge, attitudes, and self-efficacy are influenced by a more inclusive tool. In Phase I, semi-structured interviews were conducted with students (n = 33) and staff (n = 10) at campus sexual assault centers at the three University of Michigan (UM) campuses to explore power and control tactics utilized by perpetrators on college campuses.

ARX788, a Site-specific Anti-HER2 Antibody-Drug Conjugate, Demonstrates Potent and Selective Activity in HER2-low and T-DM1-resistant Breast and Gastric Cancers.

First-generation antibody-drug conjugates (ADC) are heterogeneous mixtures that have shown clinical benefit, but generally exhibited safety issues and a narrow therapeutic window due, in part, to off-target toxicity caused by ADC instability. ARX788 is a next-generation, site-specific anti-HER2 ADC that utilizes a unique nonnatural amino acid-enabled conjugation technology and a noncleavable Amberstatin (AS269) drug-linker to generate a homogeneous ADC with a drug-to-antibody ratio of 1.9.

Nonclinical Development of Next-generation Site-specific HER2-targeting Antibody-drug Conjugate (ARX788) for Breast Cancer Treatment.

Conventional antibody-drug conjugates (ADC) utilize native surface-exposed lysines or cysteines on the antibody of interest to conjugate cytotoxic payload. The nonspecific conjugation results in a mixture with variable drug-to-antibody ratios (DAR), conjugation sites, and ADCs that are often unstable in systemic circulation. ARX788 is an ADC consisting of a HER2-targeting antibody site-specifically conjugated with a potent antitubulin cytotoxic drug-linker, AS269.

Development of low-cost cardiac and skeletal muscle laboratory activities to teach physiology concepts and the scientific method.

Anatomy and Physiology courses taught at community colleges tend to focus laboratory hours primarily on anatomy as opposed to physiology. However, research demonstrates that, when instructors utilize active learning approaches (such as in laboratory settings) where students participate in their own learning, students have improved outcomes, such as higher test scores and better retention of material. To provide community college students with opportunities for active learning in physiology, we developed two laboratory exercises to engage students in cardiac and skeletal muscle physiology.

A first record of Cretaceous aphids (Hemiptera, Sternorrhyncha, Aphidomorpha) in Australia, from the Lower Cretaceous Koonwarra Fossil Bed, Victoria.

This paper describes the first species of aphid from the Lower Cretaceous Koonwarra Fossil Bed of the Gippsland Basin, southeastern Victoria, Australia. This aphid, herein named Koonwarraphis rotundafrons gen. & sp.

FGF21 analogs of sustained action enabled by orthogonal biosynthesis demonstrate enhanced antidiabetic pharmacology in rodents.

Fibroblast growth factor 21 (FGF21) mitigates many of the pathogenic features of type 2 diabetes, despite a short circulating half-life. PEGylation is a proven approach to prolonging the duration of action while enhancing biophysical solubility and stability. However, in the absence of a specific protein PEGylation site, chemical conjugation is inherently heterogeneous and commonly leads to dramatic loss in bioactivity.

Modeling the influence of ethanol on the adsorption and desorption of selected BTEX compounds on bentonite and kaolin.

The influence of ethanol on the adsorption capacity and desorption kinetics of benzene and toluene on bentonite and kaolin through modeling and experimental study was investigated. The results showed that the adsorption capacity of both soils for the target compounds decreased as ethanol content increased. As ethanol content increased from 0 to 50%, the adsorption capacity for benzene and toluene on bentonite decreased from 3.

An in vitro comparison of the intraradicular dentin bond strength of Resilon and gutta-percha.

The purpose of this study was to compare the micropush-out bond strength of Resilon to that of gutta-percha. Extracted human anterior teeth were used for evaluation. The crowns were removed and the root canals were instrumented with Gates Glidden drills and 0.

The causes, prevention, and clinical management of broken endodontic rotary files.

Complications can occur during many dental procedures. The prepared clinician responds by either correcting the problem during treatment, or, ideally, preventing the problem from occurring in the first place. In endodontic treatment separated rotary Ni-Ti files are a common procedural problem.

Saving lives and conserving blood: changing blood transfusion practices at St. John's Hospital, Springfield, Missouri.

We measured mean transfusion rates for 11 conditions accounting for the majority of inpatient blood transfusions and the pre-transfusion hemoglobin threshold triggering the transfusion. We then developed evidence-based recommendations for lower blood hemoglobin transfusion 'triggers.' Implementation of the transfusion guidelines and consensus building has decreased blood transfusion for the eleven conditions at St.

Determination of salbutamol in human plasma and urine by high-performance thin-layer chromatography.

A rapid, accurate and sensitive method for the determination of salbutamol in plasma and urine is described. Salbutamol is extracted using solid-phase techniques and converted to an indoaniline dye by reaction with dimethyl-p-phenylenediamine. The indoaniline is separated using high-performance thin-layer chromatography and quantified by absorption microdensitometry at 650 nm.
