Drones (unoccupied aircraft systems) have become effective tools for wildlife monitoring and conservation. Automated animal detection and classification using artificial intelligence (AI) can substantially reduce logistical and financial costs and improve drone surveys. However, the lack of annotated animal imagery for training AI is a critical bottleneck in achieving accurate performance of AI algorithms compared to other fields.

Understanding provider perspectives, particularly in terms of adaptations made during this critical time, is a useful lens into service innovation in times of crisis and can help elucidate successful strategies for continuing the use of telehealth during the postpandemic period. Fourteen providers from 11 different service agencies in a southeastern state were interviewed.

Methods: A pool of 63 items was reviewed by an expert panel, subjected to 2 additional face validity checks, and reduced to 39 items. The scale was then completed by 333 participants, and an exploratory factor analysis and confirmatory factor analysis were conducted.
Social workers and other healthcare professionals face increasing pressure to expand access, efficiency, and quality of healthcare to rural patients. Telehealth has become a viable and necessary tool to address gaps in healthcare for rural areas. Unfortunately, little is known about the benefits and challenges of using these services to meet the needs of rural communities.

Design: A longitudinal point prevalence study was conducted during August 17-September 4, 2020 (period 1) and during December 2-23, 2020 (period 2).
Setting: Community based teaching health system.
The multikinase inhibitor sorafenib, and opening of voltage dependent anion channels (VDAC) by the erastin-like compound X1 promotes oxidative stress and mitochondrial dysfunction in hepatocarcinoma cells. Here, we hypothesized that X1 and sorafenib induce mitochondrial dysfunction by increasing reactive oxygen species (ROS) formation and activating c-Jun N-terminal kinases (JNKs), leading to translocation of activated JNK to mitochondria. Both X1 and sorafenib increased production of ROS and activated JNK.

This study explored the types of innovations resulting from one such statewide behavioral health initiative, as well as the facilitators and barriers to implementing these innovations, from the perspective of the substance use agencies involved in the initiative. Data were collected through semistructured interviews with 67 agency stakeholders and 93 agency progress reports.

Previous research has acknowledged that there is a relationship between victimization and later delinquency, but the specific attributes of this relationship are unclear because measures of both direct and indirect victimization are rarely explored in a single study. We included both indirect and direct victimization to examine which form of victimization was a stronger predictor of substance use, fighting, running away, and sex work among girls committed to a juvenile justice facility. Findings indicated that direct victimization was typically a more salient predictor of delinquency than indirect forms of victimization.

Interprofessional education (IPE) efforts, therefore, have to prepare students for this type of leadership. The purpose of this study was to understand how students' perceptions of leadership change as a result of embedding a collaborative leadership model, the Social Change Model (SCM) of leadership, in an IPE course.

High free tubulin in cancer cells closes voltage dependent anion channels (VDAC) to decrease mitochondrial membrane potential (ΔΨ), an effect antagonized by erastin, the canonical promotor of ferroptosis. Previously, we identified six compounds (X1-X6) that also block tubulin-dependent mitochondrial depolarization.

Flux of metabolites across the mitochondrial outer membrane occurs through voltage-dependent anion channels (VDAC). In cancer cells, free dimeric tubulin induces VDAC closure and dynamically regulates mitochondrial membrane potential (ΔΨ).

Nine focus groups (n=45) were conducted with current and former male and female recipients of treatment services in one south eastern state. Using inductive thematic analysis, transcripts were analyzed to identify key themes related to parenting.

Interactive programs, compared to more didactic, lecture style programs, involve participants in skill-building activities and focus on interaction among participants. A systematic literature search was conducted for English-language studies from January 1998 to March 2014.

The mitochondrial membrane potential (ΔΨ), a component of Δp, drives release of mitochondrial ATP(4-) in exchange for cytosolic ADP(3-) via the electrogenic adenine nucleotide translocator (ANT) located in the mitochondrial inner membrane, which leads to a high cytosolic ATP/ADP ratio up to >100-fold greater than matrix ATP/ADP. In rat hepatocytes, ANT inhibitors, bongkrekic acid (BA), and carboxyatractyloside (CAT), and the F1FO-ATP synthase inhibitor, oligomycin (OLIG), inhibited ureagenesis-induced respiration.

The purpose of this study was to explore the nature of relationships and communication among adolescent children of incarcerated mothers, primary caregivers, and incarcerated mothers using pilot data. Semi-structured individual interviews were conducted with youth aged 12-17 (n=7) and caregivers (n=6) recruited through a non-profit organization working with incarcerated mothers and their children.

We used factor analysis to examine patterns of traumatic events experienced by women in jail and explored how these patterns were associated with 4 psychiatric disorders (posttraumatic stress disorder [PTSD], major depression, bipolar disorder, and substance use disorder) observed in this sample.
Method: A total of 464 women from 9 jails in 4 geographic regions in the United States comprised the sample.

Potent synthetic cannabinoids (SCBs) are illegally distributed drugs of abuse that are frequently consumed in spite of their adverse consequences. This study was designed to determine if the toxicity observed in adults also extends to the prenatal period by examining the developmental toxicity/teratogenicity of one of these SCBs, CP-55,940, in a mammalian model. First, immunohistochemistry was employed for cannabinoid receptor 1 (CB1) localization within gestational day (GD) 8 mouse embryos; this receptor was identified in the cranial neural plate, suggesting that the endogenous cannabinoid system may be involved in normal development.

Life History Calendars and the Juvenile Victimization Questionnaire were used to collect data from 100 delinquent girls to (a) examine range and co-occurrence of different types of violence over the life span, (b) examine independent and cumulative trajectories of risk for varied types of victimization, and (c) examine the relationship of victimization to girls' offending. Risk trajectories demonstrate critical risk periods for different forms of violence exposure. Cox regression was used to examine the predictive value of different forms of violence exposure for the onset of delinquent and criminal behavior.

Complicating these high rates is the high comorbidity of SMI with SUD and trauma histories. Yet, incarcerated women have significantly less access to treatment and health services while incarcerated than men.
