Psychiatric Social Work Program in Rural Community: A Multi-sectoral Initiative

Background: Community based programmes with the combined focus on promotive and curative aspects are the planned objective of interventions and services organised by psychiatric social workers in a rural community for identification and treatment linkage provision for mental health problems. Aim of the Study: The aim of the survey is to find out the mental health related problems in the rural community and to provide psychiatric social work services in the rural community by providing linkages to community based psychiatric extension services. Methods:  This research cum intervention program used a survey method, with the universe of the study consisting of all the persons residing in Samardoloni village in Sootea Block, in Sonitpur district of Assam.  People, who are permanent members of their respective household of Samardoloni village, formed the sample for the present study. Household survey was done with data being collected through the semi-structured tool for socio-demographic data and clinical information. Psychiatric social work programme was conducted in the community for awareness' and de-stigmatization of mental illness. Results: In the survey, 271 households were assessed and it was found that in the surveyed village, forty-seven (47) persons were identified as having mental illness and other related problems; eleven (11) persons were having Epilepsy, thirteen (13) persons had Psychosis, eight (8) persons had Somatization disorder, five (5) persons had Child related psychiatric disorder  and ten(10) people were having substance related disorders. Awareness program on mental health and illness was conducted in the community at three levels. First, at the Community-level, sensitization for acceptance and de-stigmatizations of mental illness, secondly, at the School-level, addressing various problems of children and adolescents for teachers and children, and thirdly, at the group level, targeted knowledge and information was given to the persons identified with mental disorders during the survey and were further motivated to access treatment at the local PHC where psychiatric treatment was available. Conclusion: Psychiatric social worker services can address various mental health issues through inter-sectoral collaboration with local rural functionaries. Focused activities for various groups can be useful at community-level for identifications, acceptance, de-stigmatization of mental illness and providing psychosocial care in the community. The role of a psychiatric social worker as a networker for linkage building and coordinating is emphasized apart from being a researcher and as an interventionist in psychiatric social work.  Initiative resulted in treatment accession for 37 patients of the 47 identified. Community participation formed an integral component in mobilizing and utilizing community members and for early identification and linkage provision for treatment. The initiative impacted inter-sectoral systems to plan, coordinate, assess, educate, counsel and link- up and sustain within the community resources.

9S1R Nullomer Peptide Induces Mitochondrial Pathology, Metabolic Suppression, and Enhanced Immune Cell Infiltration, in Triple-Negative Breast Cancer Mouse Model

Nullomers are the shortest strings of absent amino acid (aa) sequences in a species or group of species. Primes are those nullomers that have not been detected in the genome of any species. 9S1R is a 5-aa peptide prime sequence attached to 5-arginine aa, used to treat triple negative breast cancer (TNBC) in an in vivo mouse model. This unique peptide, administered with a trehalose carrier (9S1R-NulloPT), offers enhanced solubility and exhibits distinct anti-cancer effects against TNBC. In our study, we investigated the effect of 9S1R-NulloPT on tumor growth, metabolism, metastatic burden, tumor immune-microenvironment (TME), and transcriptome of aggressive mouse TNBC tumors. Notably, treated mice had smaller tumors in the initial phase of the treatment, as compared to untreated control, and diminished in vivo and ex vivo bioluminescence at later-stages - indicative of metabolically quiescent, dying tumors. The treatment also caused changes in TME with increased infiltration of immune cells and altered tumor transcriptome, with 365 upregulated genes and 710 downregulated genes. Consistent with in vitro data, downregulated genes were enriched in cellular metabolic processes (179), specifically mitochondrial TCA cycle/oxidative phosphorylation (44), and translation machinery/ribosome biogenesis (45). The upregulated genes were associated with the developmental (13), ECM organization (12) and focal adhesion pathways (7). In conclusion, our study demonstrates that 9S1R-NulloPT effectively reduced tumor growth during its initial phase, altering the TME and tumor transcriptome. The treatment induced mitochondrial pathology which led to a metabolic deceleration in tumors, aligning with in vitro observations

Meroterpenoids: A Comprehensive Update Insight on Structural Diversity and Biology.

Funder: This research was funded by the Deanship of Scientific Research at Princess Nourah bint Abdulrahman University through the Fast-track Research Funding ProgramMeroterpenoids are secondary metabolites formed due to mixed biosynthetic pathways which are produced in part from a terpenoid co-substrate. These mixed biosynthetically hybrid compounds are widely produced by bacteria, algae, plants, and animals. Notably amazing chemical diversity is generated among meroterpenoids via a combination of terpenoid scaffolds with polyketides, alkaloids, phenols, and amino acids. This review deals with the isolation, chemical diversity, and biological effects of 452 new meroterpenoids reported from natural sources from January 2016 to December 2020. Most of the meroterpenoids possess antimicrobial, cytotoxic, antioxidant, anti-inflammatory, antiviral, enzyme inhibitory, and immunosupressive effects

The malleable brain: plasticity of neural circuits and behavior: A review from students to students

One of the most intriguing features of the brain is its ability to be malleable, allowing it to adapt continually to changes in the environment. Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic connections, referred to as long-term potentiation (LTP) and long-term depression (LTD) respectively. Such phenomena have been described in a variety of model organisms, which are used to study molecular, structural, and functional aspects of synaptic plasticity. This review originated from the first International Society for Neurochemistry (ISN) and Journal of Neurochemistry (JNC) Flagship School held in Alpbach, Austria (Sep 2016), and will use its curriculum and discussions as a framework to review some of the current knowledge in the field of synaptic plasticity. First, we describe the role of plasticity during development and the persistent changes of neural circuitry occurring when sensory input is altered during critical developmental stages. We then outline the signaling cascades resulting in the synthesis of new plasticity-related proteins, which ultimately enable sustained changes in synaptic strength. Going beyond the traditional understanding of synaptic plasticity conceptualized by LTP and LTD, we discuss system-wide modifications and recently unveiled homeostatic mechanisms, such as synaptic scaling. Finally, we describe the neural circuits and synaptic plasticity mechanisms driving associative memory and motor learning. Evidence summarized in this review provides a current view of synaptic plasticity in its various forms, offers new insights into the underlying mechanisms and behavioral relevance, and provides directions for future research in the field of synaptic plasticity.Fil: Schaefer, Natascha.

Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year-on-year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non-vesicular extracellular particles, characterisation and functional studies. To address the challenges and opportunities in this rapidly evolving field, the International Society for Extracellular Vesicles (ISEV) updates its 'Minimal Information for Studies of Extracellular Vesicles', which was first published in 2014 and then in 2018 as MISEV2014 and MISEV2018, respectively. The goal of the current document, MISEV2023, is to provide researchers with an updated snapshot of available approaches and their advantages and limitations for production, separation and characterisation of EVs from multiple sources, including cell culture, body fluids and solid tissues. In addition to presenting the latest state of the art in basic principles of EV research, this document also covers advanced techniques and approaches that are currently expanding the boundaries of the field. MISEV2023 also includes new sections on EV release and uptake and a brief discussion of in vivo approaches to study EVs. Compiling feedback from ISEV expert task forces and more than 1000 researchers, this document conveys the current state of EV research to facilitate robust scientific discoveries and move the field forward even more rapidly

Factors affecting trust in publishing personal information in online social network: An empirical study of Malaysia’s Klang Valley users

Online Social Networking (OSN) is a platform that enables one to socialize over the world online without having to meet anyone physically or face to face. However, privacy in OSN sites is becoming a main concern for users because of the potential threats that come with sharing one’s personal information online. The purpose of our study was to examine the key factors that influence the trust in publishing personal information on Online Social Network (OSN) sites in Malaysia. Primary data were gathered from 201 users comprising university students and working adults residing in the Klang Valley. Five factors were selected to gauge the users’ perception of potential threats , namely, security/privacy of the website, word of mouth of family and friends, functional motives of OSN users, social motives of OSN users and psychological motives of OSN users. Results of the study showed that security/privacy, word of mouth, functional motives and social motives significantly affected the publishing of respondents’ personal information on online social network sites. The implication is that the largest challenge of both now and in the future, in terms of users protecting themselves and their information, will be to find out and understand how to effectively access and change the privacy settings offered by all OSN sites
