Adenine metabolism is important for common bean (Phaseolus vulgaris L) productivity since this legume uses ureides derived from the oxidation of purine nucleotides, as their primary nitrogen storage molecules. Purine nucleotides are produced from de novo synthesis or through salvage pathways. Adenine phosphoribosyl transferase (APRT) is the enzyme dedicated to adenine nucleobase salvage for nucleotide synthesis, but it also acts on the inactivation of cytokinin bases.

Among people living with HIV (PLWH), 50% report substance use disorders (SUDs), and 30-61% report posttraumatic stress disorder (PTSD). Comorbid PTSD/SUD/HIV has been linked to faster HIV progression and twice the rate of death, lower medical adherence and retention, and increased viral load compared to PLWH without co-occurring PTSD or SUD. A critical first step in establishing comprehensive mental health services for PLWH is the implementation of an evidence-based screening protocol for PTSD and SUDs to facilitate referrals to specialty mental health providers.

Despite high rates of Post-Traumatic Stress Disorder (PTSD) in persons living with HIV (PLWH) and poor HIV-related health outcomes associated with PTSD, an effective evidence-based treatment for PTSD symptoms in PLWH does not exist. Negative reinforcement conceptual models posit that avoidant behavior (hallmark symptom of PTSD) demonstrated by PLWH with co-occurring PTSD can contribute to poor antiretroviral therapy (ART) adherence. However, research evaluating the impact of evidence-based treatment for PTSD among HIV infected populations on HIV outcomes is scarce.

Experiences of racial discrimination are pervasive among Black youth, resulting in psychosocial problems such as depression and anxiety. Rumination plays a key role in linking racial discrimination and internalizing concerns. Developmental age has also been shown to influence the extent to which racial discrimination and rumination impact mental health; however, studies have yet to explore the interplay between these factors.

Objective: The purpose was to examine associations between HIV care engagement and mental health symptoms among persons living with HIV (PLWH) receiving ART. This study builds upon previous findings indicating a significant association between mental health and retention in HIV care, while also advancing the literature by examining the impact of substance use on this link, as well as potential bidirectional associations.

Method: Participants of the current study were 493 patients who engaged in care and received antiviral therapy (ART) from Infectious Disease physicians between 2017 and 2019 in a large academic medical center.

Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas) gene editing has become a powerful tool in genome manipulation for crop improvement. Advances in omics technologies, including genomics, transcriptomics, and metabolomics, allow the identification of causal genes that can be used to improve crops. However, the functional validation of these genetic components remains a challenge due to the lack of efficient protocols for crop engineering.

Approximately one-third of college students engage in heavy episodic drinking. Although White students drink more than Black students, White individuals are more likely to mature out of heavy drinking, whereas Black individuals drink more as they age and experience disproportionate alcohol-related consequences. Compared to their White counterparts, limited research has examined factors associated with alcohol use among Black college students.

Adolescent pregnancy remains a health issue worldwide also in developed countries, since it has been associated with adverse maternal and neonatal outcomes. Some data suggest that very young adolescents have higher risk, likely due to immaturity. Therefore, we aimed to assess the influence of maternal age on complications during gestation and labor in pregnant women between 13 and 19 years of age.

Posttraumatic stress disorder (PTSD) is common in women who experienced Military Sexual Trauma (MST). Despite Veterans Affairs Medical Center-wide screening and tailored MST services, substantial barriers to care exist, and about 50 % of those who start evidence-based treatment for PTSD drop out prematurely. Home-based telemedicine (HBT) may reduce logistical and stigma related barriers to mental health care, thereby reducing dropout.

Military sexual trauma (MST), defined as sexual assault or repeated, threatening sexual harassment while in the military, is associated with increased risk of long-term mental and physical health problems, with the most common being symptoms of post-traumatic stress disorder (PTSD) and depression. In addition to PTSD and depression, MST is linked to difficulties in emotion regulation as well as poor treatment engagement. Thus, it is important to examine these correlates, and how they affect postintervention symptom reduction in this vulnerable population.

Drought is probably the most harmful stress affecting common bean crops. Domestication, worldwide spread and local farming practices has entailed the development of a wide variety of common bean genotypes with different degrees of resistance to water stress. In this work, physiological and molecular responses to water stress have been compared in two common bean accessions, PHA-0683 and PMB-0220, previously identified as highly and moderately resistant to water stress, respectively.

Although substance use problems are highly prevalent among adolescents and emerging adults, this population does not regularly receive substance use prevention programming in their communities. Low perceived risk of substance use, which is linked to actual behavior, may contribute to low rates of engagement in community prevention efforts for substance use. To examine this, the current study used a mixed methods approach to: (1) examine the relationship between engagement in prevention education and substance use; and, (2) analyze qualitative data on education programs offered in the community to help identify strengths and gaps in prevention resources.

Drought is one of the most critical factors limiting legume crop productivity. Understanding the molecular mechanisms of drought tolerance in the common bean is required to improve the yields of this important crop under adverse conditions. In this work, RNA-seq analysis was performed to compare the transcriptome profiles of drought-stressed and well-irrigated plants of a previously characterized drought-tolerant common bean landrace.

While evidence-based interventions can help the substantial number of veterans diagnosed with comorbid PTSD and depression, an emerging literature has identified sleep disturbances as predictors of treatment nonresponse. More specifically, predicting effects of residual insomnia and nightmares on postintervention PTSD and depressive symptoms among veterans with comorbid PTSD and depression has remained unclear. The present study used data from a clinical trial of Behavioral Activation and Therapeutic Exposure (BA-TE), a combined approach to address comorbid PTSD and depression, administered to veterans (N = 232) to evaluate whether residual insomnia and nightmare symptoms remained after treatment completion and, if so, whether these residual insomnia and nightmare symptoms were associated with higher levels of comorbid PTSD and depression at the end of treatment.
