Microbes exist at and colonize mucosal surfaces striking a balance with the host immune system, so that these microbes can thrive on host tissues without causing pathology. Because of this, mucosal barrier-colonizing bacteria can be leveraged to act as long-term delivery vehicles for naturally derived therapeutics. Here, we use a mouse model of corneal wound healing to show that the eye-colonizing bacterium, Corynebacterium mastitidis (C.

We examined how students' food insecurity related to their demographic information, academic experiences, use of food programs, and reflections on food during the COVID-19 pandemic. 246 NYC undergraduates during the first 9 months of the pandemic. Students reported on food insecurity (eg, USDA's 10-item AFSSM), household income, impact of food insecurity on academics, GPA, and use of food programs.

We also considered the extent to which motivational control could be promoted or burdened when young people seek help and encouragement from others in their careers. Based on the importance of shared agency in life goal pursuit, it was hypothesized that shared agency (i.

Utilizing latent profile analysis, we examined unique profiles of past, present, and future SSS among 401 college students in the United States and tested associations between these profiles and psychological well-being (ie, depressive symptoms, negative affect, positive affect, and flourishing), controlling for family socioeconomic status (SES). Results revealed four profiles: (8%), (18%), (43%), and (31%).

That individuals attain socioeconomic status (SES) through their own effort and ability, which is a staple pillar of the meritocratic ethos and has been a popular topic of inquiry within social psychology. However, this focus on merit overshadowed other important causal factors that contribute to one's SES, such as opportunity and chance. This study presents psychometrically validated scales measuring one's causal beliefs of SES attainment for themselves (agency beliefs) and others (society beliefs).

Why do people contribute to the well-being of others? What promotes or hinders their contribution? Framed by expectancy-value theory and the motivational theory of life span development, we use data from the Midlife in the United States National longitudinal study (MIDUS I, II, and III) to examine how individuals' perceived contributions to the well-being of others develop across adulthood, in the related but distinct forms of overall prosociality (more other-focused) and generativity (more self-focused). Our findings show that prosociality and generativity display similar, yet distinct trajectories, peaking in midlife a decade apart from each other, when expectancy and value for prosocial behavior are highest. Moreover, expectancy as reflected in perceived control and control strivings, and value as indicated by agreeableness, predict individuals' prosociality and generativity.

We address these questions using longitudinal data from the Midlife in the United States study. We find that relationship quality with romantic partners, family, and friends is positively linked with better health and well-being concurrently and longitudinally. Cross-lagged analyses indicate that romantic relationships are more predictive of than predicted by health and well-being, family relationships are more predicted by than predictive of health and well-being, and friendships are both predicted by and predictive of health and well-being.

We probed mouse neocortex during visual discrimination using a red-shifted channelrhodopsin (ChRmine, discovered through structure-guided genome mining) alongside multiplexed multiphoton-holography (MultiSLM), achieving control of individually specified neurons spanning large cortical volumes with millisecond precision. Stimulating a critical number of stimulus-orientation-selective neurons drove widespread recruitment of functionally related neurons, a process enhanced by (but not requiring) orientation-discrimination task learning.

However, less is known about the role of cross-domain engagement during significant life course transitions that can challenge motivational resources, such as the shift to retirement. Based on the motivational theory of life span development (Heckhausen, Wrosch, & Schulz, 2010, 2019), the present study used 9-year data from the national Midlife in the United States Study (MIDUS; = 1,301, age = 57, = 6.

Vector control strategies have been hindered by mosquito and pathogen resistances, and population alteration approaches using transgenic mosquitos still have many hurdles to overcome before they can be implemented in the field. Here we report a paratransgenic control strategy in which the microbiota of Anopheles stephensi was engineered to produce an antiplasmodial effector causing the mosquito to become refractory to Plasmodium berghei.

Objective: To evaluate a smartphone mobile application (Solar Cell) delivering real-time advice about sun protection for a second time in a randomized clinical trial.
Design, Setting, And Participants: A previous trial conducted in 2012 used a randomized pretest-posttest design.
Importance: Mobile smartphones are rapidly emerging as an effective means of communicating with many Americans. Using mobile applications (apps), they can access remote databases, track time and location, and integrate user input to provide tailored health information.
Objective: A smartphone mobile app providing personalized, real-time sun protection advice was evaluated in a randomized clinical trial.
Background: Developing innovative delivery methods is needed to overcome time and logistic barriers to in-person participation in evidence-based parent training (PT) programs.
Purpose: The purpose of this paper is to (a) describe the systematic process for adapting an evidence-based group PT program (the Chicago Parent Program) to a tablet-based delivery format, (b) present the adapted program, and (c) discuss opportunities and challenges of adapting evidence-based programs for alternative delivery methods.
Methods: To ensure consistency with the original program and relevance to the intended program recipients, three groups-parents (n = 10), CPP developers (n = 3), and digital delivery experts- were engaged throughout the systematic steps of the delivery adaptation of the Chicago Parent Program (eCPP).
Established standards for first-line hypertension management include lifestyle modification and behavior change. The degree to which and how lifestyle modification is systematically integrated into studies of first-line drug management for hypertension is of methodological and clinical relevance. This study systematically reviewed the methodology of articles from a recent Cochrane review that had been designed to inform first-line medical treatment of hypertension and was representative of high quality established clinical trials in the field.
