tient pain services are not working profitably. Only 39.7% of the QSV pain therapists provided fellowship training for physicians and 57.6% were planning to retire during the next 10years.

Highly specialized pain therapists are dissatisfied because of the lack of independence of the organizational structure of pain management care and the insufficient interdisciplinary network in outpatient pain management. A possible solution for abetter pain management care and the recruitment problems may be the establishment of aboard certification for pain management.

RAS proteins comprise a conserved GTPase domain and a C-terminal lipid-modified tail that is unique to each isoform. The GTPase domain is a 'switch' that regulates multiple signaling cascades that drive cell growth and proliferation when activated by binding GTP, and the signal is terminated by GTP hydrolysis. Oncogenic RAS mutations disrupt the GTPase cycle, leading to accumulation of the activated GTP-bound state and promoting proliferation. RAS is a key target in oncology, however it lacks classic druggable pockets and has been extremely challenging to target. RAS signaling has thus been targeted indirectly, by harnessing key downstream effectors as well as upstream regulators, or disrupting the proper membrane localization required for signaling, by inhibiting either lipid modification or 'carrier' proteins. As a small (20 kDa) protein with multiple conformers in dynamic equilibrium, RAS is an excellent candidate for NMR-driven characterization and screening for direct inhibitors. Several molecules have been discovered that bind RAS and stabilize shallow pockets through conformational selection, and recent compounds have achieved substantial improvements in affinity. NMR-derived insight into targeting the RAS-membrane interface has revealed a new strategy to enhance the potency of small molecules, while another approach has been development of peptidyl inhibitors that bind through large interfaces rather than deep pockets. Remarkable progress has been made with mutation-specific covalent inhibitors that target the thiol of a G12C mutant, and these are now in clinical trials. Here we review the history of RAS inhibitor development and highlight the utility of NMR and integrated biophysical approaches in RAS drug discovery.A procedure is presented for the substantial simplification of 2D constant-time 13C-1H heteronuclear single-quantum correlation (HSQC) spectra of 13C-enriched proteins. In this approach, a single pulse sequence simultaneously records eight sub-spectra wherein the phases of the NMR signals depend on spin topology. Signals from different chemical groups are then stratified into different sub-spectra through linear combination based on Hadamard encoding of 13CHn multiplicity (n = 1, 2, and 3) and the chemical nature of neighboring 13C nuclei (aliphatic, carbonyl/carboxyl, aromatic). This results in five sets of 2D NMR spectra containing mutually exclusive signals from (i) 13Cβ-1Hβ correlations of asparagine and aspartic acid, 13Cγ-1Hγ correlations of glutamine and glutamic acid, and 13Cα-1Hα correlations of glycine, (ii) 13Cα-1Hα correlations of all residues but glycine, and (iii) 13Cβ-1Hβ correlations of phenylalanine, tyrosine, histidine, and tryptophan, and the remaining (iv) aliphatic 13CH2 and (v) aliphatic 13CH/13CH3 resonances. As HSQC is a common element of many NMR experiments, the spectral simplification proposed in this article can be straightforwardly implemented in experiments for resonance assignment and structure determination and should be of widespread utility.Drug dependence may affect the neurotransmitter system levels in the human body. This study recruited 113 healthy control subjects, 118 heroin-dependent patients and 118 methamphetamine-dependent patients and examined the serum 5-HT, dopamine, glutamate and norepinephrine levels in the 349 volunteers. ELISA assays demonstrated that the serum 5-HT levels were significantly reduced in the drug-dependent patients, whereas the serum dopamine and glutamate levels were both significantly increased in the drug-dependent patients when compared with control subjects. In contrast, the norepinephrine levels did not exhibit a significant difference between the drug-dependent and control subjects. We also used qRT-PCR to analyze the transcriptional expression levels of 5-HT1A, 5-HT1B, dopmaine-D1 and dopamine-D2 receptors in the blood of drug-dependent patients and controls, and the results show that only 5-HT1B receptor levels were dysfunctional in the heroin abusers. In addition, our results suggest that serum 5-HT, dopamine, and glutamate levels had the potential to differ between drug abusers and controls, and combining those three potential biomarkers provided an accurate means to differentiate between the drug-dependent and control subjects. Taken together, our study reveals a differential profile of neurotransmitters in the heroin-dependent patients and methamphetamine-dependent patients, and this revelation may contribute to understanding the pathophysiology of drug addiction.Past research suggests that neighborhood structural and social environments are important contextual factors associated with children's development; however, investigations of the long-term effects of neighborhood environments in early childhood on subsequent adolescents' social and behavioral outcomes remain limited. Further, it is unclear whether and how the home environment as a mediating mechanism links neighborhood conditions and adolescents' outcomes. Using national surveys from multi-stressed families and census datasets, the present study aims to examine the longitudinal associations between neighborhood concentrated poverty and collective efficacy, mothers' parenting stress, exposure to adverse childhood experiences (ACEs), and later adolescent outcomes. click here Participants included 4898 children (52% boys) and their mothers (48% black, 25 years of age, on average, 64% living in poverty); children born in unmarried families (75% unmarried) were oversampled. The results suggest that neighborhood collective efficacy is associated directly and indirectly (via parenting stress and ACEs) with adolescents' behavior problems and social skills, and indirectly with their delinquency. Neighborhood concentrated poverty was indirectly related to adolescents' behavior problems, delinquency, and social skills transmitted through collective efficacy and family processes. Both mothers' parenting stress and exposure to ACEs were identified as significant mediators. This study highlights the importance of early intervention for high-risk children, programs to build community resilience and reinforce social support for vulnerable families, and policy efforts to create safe and nurturing relationships and environments.Adolescence represents a developmental period of waning academic motivation, particularly in STEM domains. To combat this, better understanding the factors that might foster STEM motivation and interest is of importance. Social factors like social competencies and feelings of belonging become increasingly important in adolescence. The current study investigated structural relations between social competencies, feelings of belonging to an informal STEM learning program, math and science efficacy and interest in a sample of 268 adolescents (Mage = 15.25; 66.8% girls; 42.5% White British or European American, 25.7% South Asian British or Asian American, 15.7% Afro-Caribbean Black British or African American 5.6% Bi-racial, and 3.0% other). Adolescents were recruited from six different informal learning sites (e.g., science museums, zoos, or aquariums) in the United States (n = 147) and the United Kingdom (n = 121). The results revealed positive relations between social competencies and belonging, and between belonging and math and science efficacy and interest. Further, the results also indicated a positive indirect effect of social competencies on efficacy and interest, via belonging. These findings have implications for guiding informal STEM programming in ways that can enhance STEM motivation and interest.Intergenerational trauma is a discrete form of trauma which occurs when traumatic effects are passed across generations without exposure to the original event. This qualitative study aimed to explore how psychiatrists understand intergenerational trauma in respect to their practice, for the purposes of identifying interventions for addressing intergenerational trauma in public mental health services. Findings revealed that psychiatrists observe intergenerational trauma frequently in their roles and try to opportunistically promote awareness of trauma with adults, and refer families to external services for supportive interventions. They feel powerless when faced with directly intervening with intergenerational trauma and required restructuring of their roles to adequately address it in public settings. Findings have implications for training, advocacy and research on the relationship between trauma and mental illness. Alongside this, there is an indicated need for examination of how systems can ensure access to appropriate services once organisations become trauma-informed.Asian countries have made great progress in the osteoporosis research over the past 20 years. Mainland China has a significant increase in the number of articles. The scientific influence of Japan ranked by citations was leading in Asia. Indian researchers published fewer articles on osteoporosis, but the overall citation was quite well.
To analyze the quantity and quality of literature regarding osteoporosis from the Asian countries/regions.

Data were obtained from the Web of Science (WoS) Core Collection on May 4, 2020. Qualitative and quantitative analysis was conducted based on WoS. Keywords analysis was performed using VosView software.

The core countries/regions in Asia in the osteoporosis research included the Mainland China (MC), Japan, South Korea, Turkey, Taiwan, India, and Iran. The core countries/regions published 4798 papers, which accounted for 33.8% of the total globally. The MC with 2242 literature and Japan with 971 were ranked second and fourth worldwide. Over the past decade, MC has puublished fewer articles on osteoporosis, but the overall quality was quite well. The core Asian countries/regions should strengthen in-depth cooperation in the future.
