Chimeric antigen receptor macrophages (CAR-M) sensitize HER2+ solid tumors to PD1 blockade in pre-clinical models.

We previously developed human CAR macrophages (CAR-M) and demonstrated redirection of macrophage anti-tumor function leading to tumor control in immunodeficient xenograft models. Here, we develop clinically relevant fully immunocompetent syngeneic models to evaluate the potential for CAR-M to remodel the tumor microenvironment (TME), induce T cell anti-tumor immunity, and sensitize solid tumors to PD1/PDL1 checkpoint inhibition. In vivo, anti-HER2 CAR-M significantly reduce tumor burden, prolong survival, remodel the TME, increase intratumoral T cell and natural killer (NK) cell infiltration, and induce antigen spreading.

Effect of Pre-Processing Treatment and Concentration of , , and Varieties on Texture and Consumer Attribute Preference of Crackers.

This study investigates the effects of three brown seaweed species (, , and ), their pre-processing treatments, and incorporation percentages on the physical and sensory properties of crackers. Significant ( ≤ 0.001) two-way and three-way interactions were observed for moisture content, with seaweed addition generally resulting in drier crackers.

Investigation of an Outbreak of Equine Herpesvirus-1 Myeloencephalopathy in a Population of Aged Working Equids.

The objective of this study was to describe an outbreak of equine herpesvirus-1 myeloencephalopathy (EHM) in a population of aged equids. The outbreak was linked to the introduction of five healthy non-resident horses 15 days prior to the first case of acute recumbency. This fulminant EHM outbreak was predisposed by the grouping of the 33 unvaccinated animals in two large pens with shared water and feed troughs.

Symptoms, Quality of Life, and Executive Function in Children Who Snore.

Introduction: Mild sleep-disordered breathing (mSDB) in children is associated with both neurobehavioral morbidity and reduced quality of life (QOL). However, the association between symptom burden and QOL with executive function is not well understood, and it is not known whether QOL and symptom burden may help identify children with neurocognitive dysfunction.

Objective: To assess associations among executive function, QOL, and symptom burden in children with mSDB.

Molecular underpinnings of plasticity and supergene-mediated polymorphism in fire ant queens.

Characterizing molecular underpinnings of plastic traits and balanced polymorphisms represent two important goals of evolutionary biology. Fire ant gynes (pre-reproductive queens) provide an ideal system to study potential links between these phenomena because they exhibit both supergene-mediated polymorphism and nutritional plasticity in weight and colony-founding behavior. Gynes with the inversion supergene haplotype are lightweight and depend on existing workers to initiate reproduction.

Biased social chromosome transmission in males of the fire ant Solenopsis invicta.

Selfish genetic elements subvert the normal rules of inheritance to unfairly propagate themselves, often at the expense of other genomic elements and the fitness of individuals carrying them. Social life provides diverse avenues for the propagation of such elements. In the fire ant Solenopsis invicta, polymorphic social organization is controlled by a social chromosome, one variant of which (Sb) enhances its own transmission in polygyne colonies through effects on caste development and queen acceptance by workers.

An Inexpensive Adaptation of a Commercial Microwave Reactor for Solid Phase Peptide Synthesis.

A home-built apparatus to perform solid phase peptide synthesis (SPPS), assisted by microwave irradiation and heating, is presented. In contrast to conventional SPPS reaction vessels, which drain solvent and byproducts via a frit located at the bottom of the vessel, the presented apparatus employs a gas dispersion tube under vacuum to remove solvent, byproducts, and excess reagents. The same gas dispersion tube supplies nitrogen gas agitation of the SPPS beads during the reaction steps of coupling and deprotection.

Optimizing Testosterone Levels and Fertility Outcomes: A Case Series on the Impact of (Maca-OG) in Andropause and Sperm Dysfunction.

Low testosterone levels in men contribute to altered sexual health, including low libido, erectile dysfunction, impaired sleep, and changes in mood and energy. Nearly half of all infertility cases are implicated by male factors, such as low testosterone levels and altered semen and sperm health. The purpose of this case series is to share the experience of two men taking a concentrated, highly bioavailable gelatinized form of specific phenotypes (sometimes referred to as colors) of (Maca-OG™) to improve reproductive health.

Variability in perinatal sleep quality is associated with an atypical cortisol awakening response and increased mood symptoms.

Objective: Pregnancy is often typified with a decrease in sleep quality, which for many women, progressively worsens across gestation and into the postpartum. A mechanism linking poor sleep with certain adverse pregnancy outcomes is dysregulation of the HPA axis resulting in atypically elevated cortisol production. While total cortisol output normally increases across pregnancy, the cortisol awakening response (CAR), a response to waking up, is influenced by factors such as stress and mood.

Impacts of zero-fare transit policy on health and social determinants: protocol for a natural experiment study.

Population-level efforts are needed to increase levels of physical activity and healthy eating to reduce and manage chronic diseases such as obesity, cardiovascular disease, and type 2 diabetes. Interventions to increase public transit use may be one promising strategy, particularly for low-income communities or populations of color who are disproportionately burdened by health disparities and transportation barriers. This study employs a natural experiment design to evaluate the impacts of a citywide zero-fare transit policy in Kansas City, Missouri, on ridership and health indicators.

Experiences of discrimination and snacking behavior in Black and Latinx children.

Little is known about how discrimination contributes to health behaviors in childhood. We examined the association between children's exposure to discrimination and their snacking behavior in a sample of youth of color (N = 164, M = 11.5 years, 49% female, 60% Black, 40% Hispanic/Latinx).

A Qualitative Scoping Review of Community Firearm Violence in Low-Income Settings.

Firearm violence is a public health crisis in the United States that disproportionately impacts community members in low-income areas who witness and experience violence and violent victimization at elevated rates compared to other socioeconomic groups, often as result of community disinvestment and systemic racism (Smith et al., Soc Sci Med 246:112587, 2020). While quantitative reviews of firearm violence and related factors exist, a review of qualitative methods and findings regarding exposure to firearm violence has not yet been conducted.

Development of the Baby Behaviors when Satiated (BABES) behavioral coding scheme.

Current infant feeding recommendations promote responsive feeding, wherein caregivers respond to infants' cues to determine feeding pace and duration, to support infant self-regulation and healthy weight outcomes. A central tenet of responsive feeding is that infants will effectively signal hunger, receptiveness to feeding, needs to disengage from feeding, and satiation, yet there is a lack of research available to support this assumption. Rather, previous research illustrates substantial variability exists for the extent to which infants exhibit behavioral cues during feeding and that many mothers feel their infants do not clearly communicate satiation, suggesting certain caregivers need tailored support to understand their infants' needs during feeding interactions.

The Role of Homologs in Planarian Nervous System Regeneration and Function.

Planarians are an excellent model for investigating molecular mechanisms necessary for regenerating a functional nervous system. Numerous studies have led to the generation of extensive genomic resources, especially whole-animal single-cell RNA-seq resources. These have facilitated predictions of neuronal subtypes, many of which have been anatomically mapped by hybridization.
