Recent Origin of a Range-Restricted Species With Subsequent Introgression in its Widespread Congener in the Phyteuma spicatum Group (Campanulaceae).

Understanding the causes of restricted geographic distributions is of major interest to evolutionary and conservation biologists. Inferring historical factors has often relied on ad hoc interpretations of genetic data, and hypothesis testing within a statistical framework under different demographic scenarios remains underutilised. Using coalescent modelling on RAD-sequencing data, we (i) test hypotheses about the origin of Phyteuma gallicum (Campanulaceae), a range-restricted endemic of central France sympatric with its widespread congener Ph.

Living between two cultures: stress in Korean American family caregivers of individuals with Alzheimer's disease and related dementias.

Objectives: Korean-American primary family caregivers of individuals with Alzheimer's disease and related dementias (ADRD) may face unique stress, attributable to the distinctive characteristics of Korean-Americans, including their immigration history, culture, and language. Using narrative inquiry, we explored caregiving experiences, focusing on stress, and identified factors contributing to stress among Korean-American family caregivers providing in-home care to individuals with ADRD.

Method: We conducted one-on-one, semi-structured interviews with 15 Korean-American family caregivers of individuals with ADRD.

Long-term methylome changes after experimental seed demethylation and their interaction with recurrent water stress in Erodium cicutarium (Geraniaceae).

The frequencies and lengths of drought periods are increasing in subtropical and temperate regions worldwide. Epigenetic responses to water stress could be key for plant resilience to these largely unpredictable challenges. Experimental DNA demethylation, together with application of a stress factor is an appropriate strategy to reveal the contribution of epigenetics to plant responses to stress.

Mental Health Needs of Inpatient Psychiatric Nurses During the COVID-19 Pandemic.

Introduction: The lack of mental health supports and resources for psychiatric nurses during the COVID-19 pandemic contributed to stress, burnout, and reduced mental wellness. Simultaneously, the pandemic's safety mitigation measures made significant changes to the inpatient psychiatric population environment making it difficult to maintain a therapeutic milieu and increased mental health challenges among staff and patients.

Aims: This study aimed to identify external and internal resilience factors, mental health support, and resources provided by organizations, and additional mental health support and resources inpatient psychiatric nurses felt would have been beneficial during the pandemic.

Mental Health Needs of Asian American Older Adults: Bridging the Inequity Gap.

The mental health needs of Asian American older adults are complex and multifaceted. Despite their rich diversity, Asian American older adults face significant challenges, including mental health stigma, cultural stress, limited English proficiency, and historical trauma. In addition, the coronavirus disease 2019 pandemic reignited preexisting anti-Asian attitudes of hostility, discrimination, blame, and scapegoating.

Partner Caregiver Resilience: A Scoping Review.

Purpose: Caring for older adults with Alzheimer's disease and related dementias (ADRD) is a significant challenge for partner caregivers (i.e., committed, married, or cohabiting individuals).

Effects of Adverse Childhood Experiences in Black Older Adults.

Adverse childhood experiences (ACEs) are socially complex events that affect children early in their lives. Research indicates that experiencing multiple ACEs increases an individual's risk for chronic physical and mental illness and premature death. Multigenerational traumas, including slavery, segregation, and institutional racism, have created an environment that perpetuates social and economic inequalities, ultimately leading to an increased risk of ACEs in Black individuals.

Evaluation of Transient Ischemic Stroke Cases Admitted to a Tertiary Hospital in Mehedinți County, South-West of Romania.

The transient ischemic attack (TIA) is a common cerebrovascular ischemic disease whose symptoms resolve within a maximum of 24 hours. The study carried out by us is a retrospective descriptive one, in which we sought to highlight the main characteristics of TIA in patients admitted to the Emergency Hospital in Turnu-Severin municipality in Mehedinți county, in the period 2016-2020, including a group of 53 patients, mainly from Mehedinți county. The analysis of the study group and the risk factors showed that TIA mainly affects the elderly, over 50 years old, with the highest incidence being recorded in the 60-80-year age groups, with an extremely low incidence under 40 years.

Homoplastic versus xenoplastic evolution: exploring the emergence of key intrinsic and extrinsic traits in the montane genus Soldanella (Primulaceae).

Specific ecological conditions in the high mountain environment exert a selective pressure that often leads to convergent trait evolution. Reticulations induced by incomplete lineage sorting and introgression can lead to discordant trait patterns among gene and species trees (hemiplasy/xenoplasy), providing a false illusion that the traits under study are homoplastic. Using phylogenetic species networks, we explored the effect of gene exchange on trait evolution in Soldanella, a genus profoundly influenced by historical introgression.

The Impact of Rapidly Progressing Neurodegenerative Disorders on Caregivers: An Integrative Literature Review.

Neurodegenerative disorders affect over 6 million people in the United States. A subset of these patients experiences symptoms that progress rapidly, along with a 5- to 10-year life expectancy (amyotrophic lateral sclerosis). This subgroup often becomes dependent on family caregivers.

Histopathological lesions induced by stroke in the encephalon.

Strokes are conditions with a high degree of morbidity and mortality worldwide. These conditions profoundly affect the quality of life of patients; in addition to physical disabilities, patients present various mental disorders, such as mood disorders, anxiety, depression, behavioral disorders, fatigue, etc. Microscopic lesions of the brain parenchyma explain the clinical symptoms and correlate with the severity of the stroke.

Combating Social Isolation in Older Adults: An Intergenerational Nursing Communication Project.

The importance of social connection to health and well-being has long been recognized. Social isolation is prevalent and impactful in the lives of older adults across care settings. A semester-long communication-focused clinical project was developed and piloted with sophomore Bachelor of Nursing Science students during Fall 2020 and replicated in Fall 2021 and 2022.

Assessment of Stroke Patients Admitted to a Tertiary Emergency County Hospital of Mehedinți - Romania.

Cerebrovascular accidents (CVA)-strokes represent a major public health problem worldwide, due to the large number of people affected. Also, there is a large number of people who die from stroke, especially in developing countries. Our study included a group of 119 patients, diagnosed with stroke and admitted to the Emergency Hospital of Drobeta Turnul-Severin, Mehedinți county, between 2016-2020.

Dementia Simulation for Family Caregivers of Persons With Dementia: A Scoping Review.

Background: Alzheimer's disease and related dementias are becoming increasingly prevalent worldwide. Persons with dementia receive substantial assistance from family caregivers over extended periods of time. Family caregivers of persons with dementia are twice as likely to report physical, emotional, and financial challenges related to caregiving compared with other types of family caregivers.

The master energy homeostasis regulator PGC-1α exhibits an mRNA nuclear export function.

PGC-1α plays a central role in maintaining mitochondrial and energy metabolism homeostasis, linking external stimuli to transcriptional co-activation of genes involved in adaptive and age-related pathways. The carboxyl-terminus encodes a serine/arginine-rich (RS) region and an RNA recognition motif, however the RNA-processing function(s) were poorly investigated over the past 20 years. Here, we show that the RS domain of human PGC-1α directly interacts with RNA and the nuclear RNA export receptor NXF1.

Ice holes microrefugia harbor genetically and functionally distinct populations of Vaccinium vitis-idaea (Ericaceae).

In the mountain terrain, ice holes are little depressions between rock boulders that are characterized by the exit of cold air able to cool down the rock surface even in summer. This cold air creates cold microrefugia in warmer surroundings that preserve plant species probably over thousands of years under extra-zonal climatic conditions. We hypothesized that ice hole populations of the model species Vaccinium vitis-idaea (Ericaceae) show genetic differentiation from nearby zonal subalpine populations, and high functional trait distinctiveness, in agreement with genetic patterns.

Recurrent allopolyploidizations diversify ecophysiological traits in marsh orchids (Dactylorhiza majalis s.l.).

Whole-genome duplication has shaped the evolution of angiosperms and other organisms, and is important for many crops. Structural reorganization of chromosomes and repatterning of gene expression are frequently observed in allopolyploids, with physiological and ecological consequences. Recurrent origins from different parental populations are widespread among polyploids, resulting in an array of lineages that provide excellent models to uncover mechanisms of adaptation to divergent environments in early phases of polyploid evolution.

Substance Use Disorders in Older Adults.

Although substance misuse (primarily alcohol and prescribed benzodiazepines and opioids) among Americans aged ≥60 years is becoming an escalating health concern, substance use disorder (SUD) is often underestimated and/or undiagnosed, preventing older adults from receiving needed treatment. Chronic medical conditions, mental health issues, and psychosocial stressors increase older adults' risks for developing SUD. Racial/ethnic minority groups (e.

Parallel adaptation to lower altitudes is associated with enhanced plasticity in Heliosperma pusillum (Caryophyllaceae).

High levels of phenotypic plasticity are thought to be inherently costly in stable or extreme environments, but enhanced plasticity may evolve as a response to new environments and foster novel phenotypes. Heliosperma pusillum forms glabrous alpine and pubescent montane ecotypes that diverged recurrently and polytopically (parallel evolution) and can serve as evolutionary replicates. The specific alpine and montane localities are characterized by distinct temperature conditions, available moisture, and light.
