Genome-wide identification and expression analysis of ARF gene family in embryonic development of Korean pine (Pinus koraiensis).

BACKGROUND: The Auxin Responsive Factor (ARF) family plays a crucial role in mediating auxin signal transduction and is vital for plant growth and development. However, the function of ARF genes in Korean pine (Pinus koraiensis), a conifer species of significant economic value, remains unclear. RESULTS: This study utilized the whole genome of Korean pine to conduct bioinformatics analysis, resulting in the identification of 13 ARF genes. A phylogenetic analysis revealed that these 13 PkorARF genes can be classified into 4 subfamilies, indicating the presence of conserved structural characteristics within each subfamily. Protein interaction prediction indicated that Pkor01G00962.1 and Pkor07G00704.1 may have a significant role in regulating plant growth and development as core components of the PkorARFs family. Additionally, the analysis of RNA-seq and RT-qPCR expression patterns suggested that PkorARF genes play a crucial role in the development process of Korean pine. CONCLUSION: Pkor01G00962.1 and Pkor07G00704.1, which are core genes of the PkorARFs family, play a potentially crucial role in regulating the fertilization and developmental process of Korean pine. This study provides a valuable reference for investigating the molecular mechanism of embryonic development in Korean pine and establishes a foundation for cultivating high-quality Korean pine.

Procedural skills workshops for primary care physicians in Israel: a comprehensive analysis.

BACKGROUND: Some of the most common complaints addressed by primary care physicians (PCPs) require manual procedures, such as lacerations repair, abscesses drainage, ingrown toenails removal, dry needling for myofascial pain syndrome, and Epley maneuver for treating benign paroxysmal positional vertigo (BPPV). The aim of this study was to describe the procedural skills workshops program for PCPs implemented in Maccabi Healthcare Services and to investigate how many PCPs have participated and used the skills since the program's inception in 2017. METHODS: In this observational study, we followed all participants in courses from 2017 to 2021. We extracted all procedures performed during these years by PCPs who learned the skill in MHS. RESULTS: During the study period, 620 PCPs participated in workshops for dry needling, soft-tissue and joint injections, BPPV treatment, minor surgical procedures, and spirometry. Most procedures performed were dry needling (average annual number 3,537) and minor surgical procedures (average annual number 361). The average annual use per physician was highest for dry needling (annual average use per physician who used the learned skill was 50.9), followed by soft tissue and joint injections (16.8), minor surgical procedures (14.8), and BPPV treatment (7.5). CONCLUSION: procedural skills workshops may expand PCPs' therapeutic arsenal, thus empowering PCPs and providing more comprehensive care for patients. Some manual skills, such as dry needling, soft tissue injections, and the Epley maneuver, were more likely to be used by participants than other skills, such as spirometry and soft tissue injections.

Additive interaction of family medical history of diabetes with hypertension on the diagnosis of diabetes among older adults in India: longitudinal ageing study in India.

BACKGROUND: The present study aimed to estimate the additive interaction of family history of diabetes and hypertension on the diagnosis of diabetes among individuals aged 45 years and above in India. The coexistence of these two exposures may act synergistically on the risk of diabetes, leading to adverse health outcomes. METHODS: The study utilized the data from the Longitudinal Ageing Study in India (LASI) Wave 1 (2017-2018). The total sample size for the current study was 58,612 individuals aged 45 years and above. Multivariable logistic regression models were employed to determine the individual and joint effect of a family history of diabetes with hypertension on diabetes. An additive model was applied to assess the interaction effect of the family medical history of diabetes with hypertension on the diagnosis of diabetes by calculating three different measures of additive interaction such as the relative excess risk ratio (RERI), attribution proportion due to interaction (AP), and synergy index (S). RESULTS: The prevalence of diabetes was three times higher among individuals with family history of diabetes (27.8% vs. 9.2%) than those without family history. Individuals with family history of diabetes (AOR: 2.47, CI: 2.11 2.89) had 2.47 times higher odds of having diabetes than those without family history. The prevalence of diabetes was significantly higher among individuals with hypertension and family history of diabetes (46.6%, 95% CI: 39.7-53.6) than those without the coexistence of family history of diabetes and hypertension (9.9%, 95% CI: 9.5-10.4), individuals with hypertension and without a family history of diabetes (22.7%, 95% CI: 21.2-24.2), and individuals with family history of diabetes and without hypertension (16.5%, 95% CI: 14.5-18.7). Moreover, the adjusted odds ratio (AOR) of the joint effect between family medical history of diabetes and hypertension on diabetes was 9.28 (95% CI: 7.51-11.46). In the adjusted model, the RERI, AP, and S for diabetes were 3.5 (95% CI: 1.52-5.47), 37% (0.37; 95% CI: 0.22-0.51), and 1.69 (95% CI: 1.31-2.18) respectively, which indicates that there is a significant positive interaction between family history of diabetes and hypertension on the diagnosis of diabetes. The study findings on interaction effects further demonstrate consistent results for two models of hypertension (self-reported hypertension and hypertensive individuals receiving medication) even after adjustment with potential confounding factors on diabetes (self-reported diabetes and individuals with diabetes receiving medication). CONCLUSIONS: The study findings strongly suggest that the interaction of family history of diabetes with hypertension has a positive and significant effect on the risk of diabetes even after adjustment with potential confounding factors. Furthermore, the findings indicate a synergistic effect, emphasizing the importance of considering both family medical history of diabetes and hypertension when assessing diabetes risk and designing preventive strategies or interventions.

Targeting FTO induces colorectal cancer ferroptotic cell death by decreasing SLC7A11/GPX4 expression.

Ferroptosis is a newly identified iron-dependent form of death that is becoming increasingly recognized as a promising avenue for cancer therapy. N6-methyladenosine (m6A) is the most abundant reversible methylation modification in mRNA contributing to tumorigenesis. However, the crucial role of m6A modification in regulating ferroptosis during colorectal cancer (CRC) tumorigenesis remains elusive. Herein, we find that m6A modification is increased during ferroptotic cell death and correlates with the decreased m6A demethylase fat mass and obesity-associated protein (FTO) expression. Functionally, we demonstrate that suppressing FTO significantly induces CRC ferroptotic cell death, as well as enhancing CRC cell sensitivity to ferroptosis inducer (Erastin and RSL3) treatment. Mechanistically, high FTO expression increased solute carrier family 7 member 11 (SLC7A11) or glutathione peroxidase 4 (GPX4) expressions in an m6A-YTHDF2 dependent manner, thereby counteracting ferroptotic cell death stress. In addition, we identify Mupirocin as a novel inhibitor of FTO, and Mupirocin induces CRC ferroptosis and inhibits tumor growth. Clinically, the levels of FTO, SLC7A11, and GPX4, are highly correlated expression in CRC tissues. Our findings reveal that FTO protects CRC from ferroptotic cell death in promoting CRC tumorigenesis through triggering SLC7A11/GPX4 expression.

How Health Professionals Identify and Respond to Perpetrators of Domestic and Family Violence in a Hospital Setting: A Scoping Review.

There is heightened awareness that a whole-of-systems approach to perpetrator responses is key to addressing domestic and family violence (DFV). This paper reports on the findings from a scoping review which mapped the international literature on how health professionals identify and respond to perpetrators of DFV within a hospital setting. A comprehensive scoping review methodology was used. The search, spanning January 2010 to January 2022, yielded 12,380 publications from four databases. Eligibility for inclusion included peer-reviewed literature with any reference to inpatient hospital health professionals identifying or responding to perpetrators of DFV. Fourteen articles were included in the final review. The review presents the literature categorized by levels of prevention, from primary, secondary, through to tertiary preventive interventions. An additional category "other practices" is added to capture practices which did not fit into existing levels. Despite glimpses into how health professionals can identify, and respond to perpetrators of DFV, the current knowledge base is sparse. The review did not identify any mandated or formal procedures for identifying and/screening or responding to perpetration of abuse in hospitals. Rather, responses to perpetrators are inconsistent and rely on the motivation, skill, and self-efficacy of health professionals rather than an embedded practice that is driven and informed by hospital policy or procedures. The literature paints a picture of missed opportunities for meaningful work with perpetrators of DFV in a hospital setting and highlights a disjuncture between policy and practice.

Impact of diversified grazing systems on milk production, nutrient use and enteric methane emissions in dual-purpose cows.

This study evaluated three continuous grazing systems: Brachiaria Brizantha, Clitoria ternatea and naturalized pastures, complemented with commercial concentrate and C. ternatea silage on milk yield, nutrient use and enteric methane (CH4) emissions. Nine multiparous cows of local Zebu breeds, with an average weight of 448 ± 87 kg, were used. The chemical composition of the food was determined. Live weight, milk production, and quality were assessed. Furthermore, serum urea, urea nitrogen, creatinine and glucose in blood were monitored, and nitrogen use efficiency were calculated. Enteric methane (CH4) emissions were estimated using Tier-2 methodology. A 3 × 3 latin square experimental design was applied. The grazing systems of B. brizantha and C. ternatea had the greater live weights of 465.8 and 453.3 kg/cow, although the latter is similar to naturalized pasture. Milk production and quality were not affected by grazing system, with the exception of the non-fat solids, where the C. ternatea system was lower (102.2 g/kg) than the other grazing systems. The crude protein and N intake, and N excretion in feces and urine were lower in naturalized pasture systems (1139.0 g/day). N outputs in milk was high in the C. ternatea system (56.3 g/cow/day). The naturalized pastures systems showed the better feed use efficiency (25.7%) compared to others. Serum urea and blood urea nitrogen were greater in B. brizantha followed by C. ternatea. Enteric CH4 emissions were indifferent among grazing systems when expressed as a percentage of greenhouse gases (7.1%). In conclusion, the grazing C. ternatea supplemented with commercial concentrate and C. ternatea silage maintains milk production and quality, reduced cow/day emissions (by 2.5%) and lowered energy losses as methane.

It is shown that COF can be a particularly suitable therapeutic approach for families with children aged four to ten. Finally, the application of COF in China with cultural differences is discussed.

Dementia Care in Rural Appalachia: Multilevel Analysis of Individual and County-level Factors.

BACKGROUND AND OBJECTIVES: Home- and community-based services (HCBS) are underutilized, despite offering significant health benefits to both care recipients and caregivers. Drawing upon Andersen's extended behavioral model of health services use, we examined individual and county-level factors influencing HCBS utilization for dementia care in rural Appalachia. RESEARCH DESIGN AND METHODS: We analyzed data from telephone interviews with 123 dementia family caregivers in rural Appalachian counties (Mage = 64.7, SDage = 12.2). Multilevel analyses were conducted to examine the effects of individual-level and county-level factors on the use of home-based services (home health care and personal care services) as well as community-based services (adult day care and transportation services). RESULTS: Results indicated that caregivers' receipt of informal support from family or friends were associated with more use of home-based services (B = 0.42, p = 0.003). Conversely, longer travel times to service providers were linked to use of fewer community-based services (B = -0.21, p < .001). Residing in counties with more home health agencies was associated with higher utilization of home-based services (B = 0.41, p = 0.046). However, higher county tax expenditures for HCBS were not linked to home-based or community-based service use. DISCUSSION AND IMPLICATIONS: Findings suggest that informal support in caring for the person living with dementia enables HCBS use in rural Appalachia. In contrast, limited geographic accessibility and service availability can impede HCBS use in rural regions. Policymakers are urged to allocate direct public funding to service providers to expand service availability in under-resourced rural regions.

Differences in discharge letter content: oncologists' vs. home care physicians' needs.

PURPOSE: To compare the details, oncologists include in discharge letters with what home care physicians need. Although discharge letters are important to share patients' information for home palliative care, few studies have compared the details, especially patients' emotions, regarding what oncologists include in discharge letters and home care physicians' needs. METHODS: This cross-sectional study was conducted by sending anonymous, self-administered questionnaires to 500 certified oncologists (OCs) and 500 directors of home care supporting clinics (HCs) in Japan between March and May 2023. The survey considered 20 potential items found in discharge letters, and compared rates of OCs including these items and HCs needs. RESULTS: Of 310 valid responses, 186 were from OCs (average age: 47.7; 29 females) and 124 from HCs (average age: 55.4; 9 females). Major items with lower inclusion rates for OCs included patients' emotions regarding medical conditions (58.4% in OCs vs. 92.6% in HCs, p < 0.001), families' emotions regarding medical conditions (60.0 vs. 92.6%, respectively, p < 0.001), patients' perceptions regarding medical conditions (84.9 vs. 94.3%, respectively, p = 0.011), families' perceptions regarding medical conditions (84.3 vs. 95.1%, respectively, p = 0.004), and potential late-onset treatment-related adverse events (79.3 vs. 92.6%, respectively, p = 0.002). Conversely, OCs included patients' activities of daily living more frequently (96.2 vs. 90.2%, respectively, p = 0.031). CONCLUSION: Transitioning to home-based palliative care may necessitate accurate information and consideration of patients' and families' perceptions and emotions regarding medical conditions in discharge letters for continuous provision of high-quality care.

Single mothers by choice - experiences of single women seeking treatment at a public fertility clinic in Denmark: A pilot study.

PROBLEM: There has been an increase in the number of single women deciding to have children through the use of medically assisted reproduction (MAR). These women are referred to as 'single mothers by choice' (SMC). BACKGROUND: Previous studies have shown how SMC can feel stigmatised. AIM: Explore if single women seeking fertility treatment in Denmark feel stigmatised. METHODS: Six single women undergoing MAR at a public fertility clinic in Denmark were interviewed. The interviews were audiotaped, anonymised, and transcribed in full, after provided written consent by the participants to take part in the study. Data were analysed using qualitative content analysis. FINDINGS: The women would have preferred to have a child in a relationship with a partner. Despite their dream of the nuclear family meaning a family group consisting of two parents and their children (one or more), the women choose to become SMC because motherhood was of such importance, and they feared they would otherwise become too old to have children. The participants did not experience stigma or negative responses to their decision, but they all had an awareness of the prejudices other people might have towards SMC. CONCLUSION: This study contributes to the understanding of the experiences of single women seeking fertility treatment in a welfare state where there are no differences in the possibilities for different social classes to seek MAR.

Impact of discharge criteria on the length of stay in preterm infants: A retrospective study in Japan and Finland.

BACKGROUND: To shorten the hospital stay in preterm infants, it is important to understand the factors extending the length of stay. AIMS: To understand how different discharge criteria affect the length of stay in preterm infants. STUDY DESIGN: A retrospective comparison study. SUBJECTS: Preterm infants born at 28 to 31 gestational weeks in 2020-2021 in a Level IV NICU in Japan (n = 22) and a Level III NICU in Finland (n = 49). OUTCOME MEASURES: We compared the most common last discharge criteria and the postmenstrual age (PMA) between the two NICUs. The potential extending effects of each discharge criterion on the length of stay were also evaluated. The discharge criteria were classified into six categories: temperature, respiration, feeding, examination, weight limit, and family readiness. RESULTS: The PMA at discharge was significantly higher in Japan than in Finland: median 40.7 (interquartile range 39.9-41.3) vs. 37.9 (36.9-39.0) weeks; r = 0.58; p < 0.001. The most common last discharge criterion was the family criterion in Japan (n = 19; 86 %) and the respiration criterion in Finland (n = 43; 88 %). In Japan, the length of stay was extended by 7.9 (standard deviation [SD] 7.0) days due to a lack of family readiness for discharge and 8.7 (SD 8.7) days due to not having discharged home with a feeding tube as a common practice. CONCLUSIONS: The length of stay of preterm infants in Japan could be notably reduced by supporting the parents' earlier readiness for discharge and allowing tube feeding at home.

Parasitic dodder expresses an arsenal of secreted cellulases with multi-substrate specificity during host invasion.

Cuscuta campestris is a common and problematic parasitic plant which relies on haustoria to connect to and siphon nutrients from host plants. Glycoside hydrolase family 9 (GH9) cellulases (EC 3.2.1.4) play critical roles in plant cell wall biosynthesis and disassembly, but their roles during Cuscuta host invasion remains underexplored. In this study, we identified 22 full-length GH9 cellulase genes in C. campestris genome, which encoded fifteen secreted and seven membrane-anchored cellulases that showed distinct phylogenetic relationships. Expression profiles suggested that some of the genes are involved in biosynthesis and remodeling of the parasite's cell wall during haustoriogenesis, while other genes encoding secreted B- and C-type cellulases are tentatively associated with degrading host cell walls during invasion. Transcriptomic data in a host-free system and in the presence of susceptible or partially resistant tomato hosts, showed for especially GH9B7, GH9B11 and GH9B12 a shift in expression profiles in the presence of hosts, being more highly expressed during host attachment, indicating that Cuscuta can tune cellulase expression in response to a host. Functional analyses of recombinant B- and C-type cellulases showed endoglucanase activities over wide pH and temperature conditions, and activities towards multiple cellulose and hemicellulose substrates. These findings improve our understanding of host cell wall disassembly by Cuscuta, and cellulase activity towards broad substrate range potentially explain its wide host range. This is the first study to provide a broad biochemical insight into Cuscuta GH9 cellulases, which based on our study may have potential applications in industrial bioprocessing.

Family concerns and relationship problems in anxious pregnant women and their associations with postnatal functional disability in Pakistan.

OBJECTIVE: Expanding on existing research suggesting that strategies to reduce prenatal anxiety can decrease functional disability (e.g., difficulties in performing everyday activities and social participation), we examined if this effect varied by type of anxiety-producing problem (i.e., having family concerns and relationship problems versus other problems) reported during pregnancy. Further, we explored if perceived social support mediated this relationship. METHODS: We used longitudinal data on 310 anxious Pakistani women who received any psychosocial intervention sessions as part of a program that was based on Cognitive Behavioral Therapy. The Psychological Outcome Profiles (PSYCHLOPS) was used to assess whether women had 'family concerns and relationship problems' or 'other problems.' The WHO Disability Assessment Schedule 2.0 assessed functional disability at six-weeks after delivery. Lack of support was measured using a 12-item Multi-dimensional Scale of Perceived Social Support. We employed linear regression to examine associations between types of problems reported during pregnancy and postnatal functional disability. Causal mediation analysis was used to assess whether postnatal social support mediated this relationship. RESULTS: Of anxious pregnant women, 34% reported family concerns or relationship problems as primary problems in pregnancy. They were more likely to report higher functional disability at six-weeks after delivery than women who reported other problems (adjusted B = 2.40, 95% CI: 0.83-3.97). Lack of overall social support (Estimateindirect = 0.69, 95% CI: 0.04-1.38) and lack of support from friends (Estimateindirect = 0.62, 95% CI: 0.01-1.29) significantly mediated the relationship. CONCLUSIONS: Findings suggest that complementing pre- and post-natal care with support programs and services that address family concerns and relationship problems, as well as enhancing social support is important to functional disability.

Quality of life of families and siblings of children with cerebral palsy treated at a reference neurorehabilitation center in Brazil.

OBJECTIVES: To investigate the associations between caregivers' burden, family quality of life (QoL), and siblings' QoL in Brazilian families of children with cerebral palsy, and to analyze siblings' QoL using as a parameter the QoL of typically developed Brazilian children. METHODS: It was a cross-sectional study. The 212 families, 212 caregivers and 131 siblings completed the Family Quality of Life Scale, Burden Interview, and KIDSCREEN-27 Child and Adolescent Version and Parents Version questionnaires at a neurorehabilitation center in southeast Brazil. Univariable and multivariable models were used. RESULTS: Family QoL significantly worsened as caregivers' burden increased (95 % CI -0.66 to -0.38). Caregivers' burden was significantly lower with increasing family QoL scores (95 % CI -0.52 to -0.30). Self-reported siblings' QoL was significantly worse than that of their typically developed peers (95 % CI -7.6 to -3.6). Self-reported siblings' QoL was significantly lower as siblings' age (95 % CI -2.52 to -0.59) and caregivers' burden (95 % CI -0.35 to -0.05) increased. Parent-reported siblings' QoL was significantly lower with increasing caregivers' burden (95 % CI -0.45 to -0.16) and higher as family QoL increased (95 % CI 0.09 to 0.37). CONCLUSIONS: The cross-sectional nature of these data precludes any statement of causality. Family QoL worsened with higher caregivers' burden levels. Lower caregivers' burden scores were associated with a higher family QoL. Siblings' QoL was impaired as compared to typically developed peers, worse among older siblings, and as caregivers' burden increased and better with higher family QoL levels. Future multicenter studies may validate the generalizability of the present findings.

The Plasmodiophora brassicae Golgi-localized UPF0016 protein PbGDT1 mediates calcium but not manganese transport in yeast and Nicotiana benthamiana.

Manganese and calcium homeostasis and signalling, in eukaryotic organisms, are regulated through membrane located pumps, channels and exchangers, including the Mn2+/Ca2+ uncharacterized protein family 0016 (UPF0016). Here we show that Plasmodiophora brassicae PbGDT1 is a member of the UPF0016 and an ortholog of Saccharomyces cerevisiae Gdt1p (GCR Dependent Translation Factor 1) protein involved in manganese homeostasis as well as the calcium mediated stress response in yeast. PbGDT1 complemented the ScGdt1p and ScPMR1 (Ca2+ ATPase) double null mutant under elevated calcium stress but not under elevated manganese conditions. In both yeast and Nicotiana benthamiana, PbGDT1 localizes to the Golgi apparatus, with additional ER association in N. benthamiana. Expression of PbGDT1 in N. benthamiana, suppresses BAX-triggered cell death, further highlighting the importance of calcium homeostasis in maintaining cell physiology and integrity in a stress environment.

Genome-wide identification and analysis of DEAD-box RNA helicases in Gossypium hirsutum.

DEAD-box RNA helicases, a prominent subfamily within the RNA helicase superfamily 2 (SF2), play crucial roles in the growth, development, and abiotic stress responses of plants. This study identifies 146 DEAD-box RNA helicase genes (GhDEADs) and categorizes them into four Clades (Clade A-D) through phylogenetic analysis. Promoter analysis reveals cis-acting elements linked to plant responses to light, methyl jasmonate (MeJA), abscisic acid (ABA), low temperature, and drought. RNA-seq data demonstrate that Clade C GhDEADs exhibit elevated and ubiquitous expression across different tissues, validating their connection to leaf development through real-time quantitative polymerase chain reaction (RT-qPCR) analysis. Notably, over half of GhDEADs display up-regulation in the leaves of virus-induced gene silencing (VIGS) plants of GhVIR-A/D (members of m6A methyltransferase complex, which regulate leaf morphogenesis). In conclusion, this study offers a comprehensive insight into GhDEADs, emphasizing their potential involvement in leaf development.

Frequency of misdiagnosis in hypertrophic cardiomyopathy.

BACKGROUND: Hypertrophic Cardiomyopathy (HCM) is characterized by unexplained left ventricle hypertrophy (LVH) ≥15 mm. The condition is often hereditary and family screening is recommended to reduce the risk of adverse disease complications and premature death among relatives. Correct diagnosis of index patients is important to ensure that only relatives at risk of disease development are invited for family screening. PURPOSE: To investigate if patients with ICD-10 codes for HCM (DI421) or hypertrophic obstructive cardiomyopathy (DI422) fulfilled recognised diagnostic criteria. METHODS: All patients with ICD-10 codes for HCM or HOCM at a Department of Cardiology were identified and had their diagnosis validated by a cardiac investigation or a review of their medical records and previous investigations. RESULTS: Two hundred and forty patients had ICD-10 codes for HCM/HOCM, of whom 202 (84%, 202/240) underwent re-examination, while 38 (16%, 38/240) had their hospital notes reviewed. Seventy-six patients (32%, n = 76/240) did not fulfil diagnostic criteria, of whom 39, (51%, n = 39/76) had normal (10 mm) or modest LV wall thickness (11-14 mm). The remaining 37 patients (49%, n = 37/76) had LVH ≥15 mm, which was well-explained by uncontrolled hypertension, (32%, n = 24/76), aortic valve stenosis (19%, n = 7/76) or wild-type amyloidosis (16%, 6/76). CONCLUSION: One-third of patients with ICD-10 codes for HCM or HOCM did not fulfil recognised diagnostic criteria. Incorrect diagnosis of HCM may cause unnecessary family investigations which may be associated with anxiety, and a waste of health care resources. This highlights the need for specialised cardiomyopathy services to ensure correct diagnosis and management of HCM.

Path Analysis Between Family Functioning and Mental Health in People With Neuropathic Pain: Roles of Pain Intensity, Self-Perceived Burden, Pain Catastrophizing, and Functional Status.

PURPOSE: This study aimed to explore the pathways between family functioning and mental health in people with neuropathic pain, as well as to discuss the mediating role of pain intensity, self-perceived burden, pain catastrophizing, and functional status. DESIGN: Cross-sectional design reported using the STROBE guidelines. METHODS: A total of 277 people with neuropathic pain completed face-to-face questionnaires to evaluate family functioning, pain intensity, pain catastrophizing, self-perceived burden, functional status, and mental health. Structural equation modeling (SEM) was constructed to analyze the pathways between these variables. RESULTS: The positive total effect between family functioning and mental health was significant and partially mediated by self-perceived burden, pain catastrophizing, and functional status. In addition, better family functioning was associated with higher pain intensity, which worsens self-perceived burden, pain catastrophizing, and functional status, masking 23.68% of the positive effects between family functioning and mental health. CONCLUSIONS: Better family functioning was associated with better mental health, as explained by reduced self-perceived burden, reduced pain catastrophizing, and improved functional status. However, this benefit may be partially masked by the relationship that better family functioning explains higher pain intensity. CLINICAL IMPLICATIONS: Nurses' comprehensive assessment and management of neuropathic pain from both the family and individual levels, such as family functioning, pain intensity, self-perceived burden, pain catastrophizing, and functional status, may be beneficial in promoting patients' mental health. In addition, it is necessary to identify why good family functioning is associated with higher pain intensity and intervene in this regard.

WHO elements - A new category of selfish genetic elements at the borderline between homing elements and transposable elements.

Homing genetic elements are a form of selfish DNA that inserts into a specific target site in the genome and spreads through the population by a process of biased inheritance. Two well-known types of homing element, called inteins and homing introns, were discovered decades ago. In this review we describe WHO elements, a newly discovered type of homing element that constitutes a distinct third category but is rare, having been found only in a few yeast species so far. WHO elements are inferred to spread using the same molecular homing mechanism as inteins and introns: they encode a site-specific endonuclease that cleaves the genome at the target site, making a DNA break that is subsequently repaired by copying the element. For most WHO elements, the target site is in the glycolytic gene FBA1. WHO elements differ from inteins and homing introns in two fundamental ways: they do not interrupt their host gene (FBA1), and they occur in clusters. The clusters were formed by successive integrations of different WHO elements into the FBA1 locus, the result of an 'arms race' between the endonuclease and its target site. We also describe one family of WHO elements (WHO10) that is no longer specifically associated with the FBA1 locus and instead appears to have become transposable, inserting at random genomic sites in Torulaspora globosa with up to 26 copies per strain. The WHO family of elements is therefore at the borderline between homing genetic elements and transposable elements.
