Spectroscopic evaluation of sesame and mustard oils treated with Murchana method.

In recent years, there has been a growing interest in traditional medicinal practices such as Ayurveda, which emphasizes the use of natural ingredients for various therapeutic purposes. Vegetable oils are an integral part of our diet and have several applications in the cosmetics and healthcare industries. These oils have also been prescribed in ancient Ayurveda texts to treat various health problems. Ayurveda prescribes a processing technique called 'Murchana' to improve the therapeutic nature of the oils. Spectroscopic techniques have been used for quality assessment in many fields. High sensitivity and a low detection rate make spectroscopy a formidable analytical technique. This study focusses on the spectroscopic analysis of sesame and mustard oils prepared using the ayurvedic processing method 'Murchana'. Spectroscopic analysis techniques including UV-Vis absorbance spectroscopy, fluorescence spectroscopy, and FTIR spectroscopy were employed to study the oils. Origin software was used to plot graphs of the spectra. The results indicated that the murchana process may reduce the components of the oil responsible for its oxidation, thereby increasing the shelf life of the oils. However, further investigations, including other spectroscopy and chromatography techniques, will prove beneficial in ascertaining the effects of the murchana process on vegetable oils. The study's findings also suggest that spectroscopic techniques can be used to supplement chemical techniques to investigate the characteristics of vegetable oils.

Synergistic therapeutics: Co-targeting histone deacetylases and ribonucleotide reductase for enhanced cancer treatment.

The development of cancer is influenced by several variables, including altered protein expression, and signaling pathways. Cancers are inherently heterogeneous and exhibit genetic and epigenetic aberrations; therefore, developing therapies that act on numerous biological targets is encouraged. To achieve this, two approaches are employed: combination therapy and dual/multiple targeting chemotherapeutics. Two enzymes, histone deacetylases (HDACs) and ribonucleotide reductase (RR), are crucial for several biological functions, including replication and repair of DNA, division of cells, transcription of genes, etc. However, it has been noted that different cancers exhibit abnormal functions of these enzymes. Potent inhibitors for each of these proteins have been extensively researched. Many medications based on these inhibitors have been successfully food and drug administration (FDA) approved, and the majority are undergoing various stages of clinical testing. This review discusses various studies of HDAC and RR inhibitors in combination therapy and dual-targeting chemotherapeutics.

Molecular Mutations in Histiocytosis: A Comprehensive Survey of Genetic Alterations.

Histiocytosis represents a group of uncommon disorders characterized by the abnormal accumulation of specialized immune cells, such as macrophages, dendritic cells, or monocyte-derived cells, in various tissues and organs. Over 100 distinct subtypes have been documented, each displaying a broad spectrum of clinical presentations and histological characteristics. Till today, histiocytosis has been addressed through a combination of chemotherapy, radiotherapy, and surgery, with varying responses from individual patients. Due to its atypical symptoms, it has been prone to misdiagnosis. Advances in our understanding of the cellular and molecular aspects of these conditions are paving the way for improved diagnostic methods and targeted therapies. Researchers have extensively investigated various mutations in patient samples. However, no paper has yet provided a comprehensive summary of the collective analysis of mutations and pathways. Hence, this paper consolidates research efforts that specifically concentrate on gene mutations identified in patient samples of different subtypes of histiocytosis. These insights are essential for developing targeted therapies and improving diagnosis. Further, it provides potential insights to enhance the development of more effective therapeutic approaches for rare diseases.

Leading wellness in healthcare: A qualitative study of leadership practices for wellness in hospital settings.

Ways of dealing with workplace stress and enhancing healthcare workers wellness are sought globally. The aim of this study was to explore healthcare leaders' practice in relation to the implementation of a workplace wellness program called SEED in the context of multiple crises (bushfires and COVID-19) affecting a local health district in New South Wales, Australia. Practice theory informed interviews (n = 23), focus groups (n = 2) and co-analysis reflexive discussions (n = 2) that were conducted with thirteen leaders and twenty healthcare workers. A pragmatic approach to program implementation for healthcare workers' wellness explored the process and actions that resulted from leadership practice in an inductive thematic analysis. Preliminary themes were presented in the co-analysis sessions to ensure the lived experiences of the SEED program were reflected and co-interpretation of the data was included in the analysis. Three key themes were identified. 1) Leading change-implementing a wellness program required leaders to try something new and be determined to make change happen. 2) Permission for wellness-implicit and explicit permission from leaders to engage in wellness activities during worktime was required. 3) Role-modelling wellness-leaders viewed SEED as a way to demonstrate leadership in supporting and caring for healthcare workers. SEED provided a platform for leaders who participated to demonstrate their leadership practices in supporting wellness activities. Leadership practices are critical to the implementation of healthcare wellness programs. The implementation of SEED at a time of unprecedented crisis gave leaders and healthcare workers opportunities to experience something new including leadership that was courageous, responsive and authentic. The study highlighted the need for workplace wellness programs to intentionally include leaders rather than only expect them to implement them. The practices documented in this study provide guidance to others developing, implementing and researching workplace wellness programs.

Wellness Warriors: a qualitative exploration of healthcare staff learning to support their colleagues in the aftermath of the Australian bushfires.

PURPOSE: Healthcare staff are on the frontline during disasters despite any personal adversity and vicarious trauma they may be experiencing. Wellness Warrior training is a post-disaster intervention developed in response to the 2019-2020 Australian bushfires to support staff in a rural hospital located on the South Coast of New South Wales, Australia. METHOD: This study explored the experiences and perspectives of 18 healthcare staff who were trained to provide emotional and peer support to their colleagues in the aftermath of a crisis. All the Wellness Warriors participated in semi-structured interviews between March and April 2020. Data were analysed using the reflexive thematic approach. RESULTS: Healthcare staff reported developing interpersonal skills around deep listening and connecting with others which allowed for hearing the core of their colleagues' concerns. The training also helped staff to feel differently about work and restored their faith in healthcare leadership. CONCLUSION: Wellness Warrior training provided staff with knowledge and skills to support their colleagues in the aftermath of a natural disaster and later during the COVID-19 pandemic. As such, these findings suggest that peer support programs such as Wellness Warriors could be one way healthcare organisations can attempt to alleviate the psychological impact of natural disasters.

The role of histone deacetylases in embryonic development.

The basic units of chromatin are nucleosomes, that are made up of DNA wrapped around histone cores. Histone lysine residue is a common location for posttranslational modifications, with acetylation being the second most prevalent. Histone acetyltransferases (HATs/KATs) and histone deacetylases (HDACs/KDACs) regulate histone acetylation, which is important in gene expression control. HDACs/KDACs regulate gene expressions through the repression of the transcription machinery. HDAC/KDAC isoforms play a major role during various stages of embryo development and neurogenesis. In specific, class I and II HDACs/KDACs are involved in cardiac muscle differentiation and development. An insight into different pathways and genes associated with embryonic development, the effect of HDAC/KDAC activity during the embryonic stem cell differentiation, preimplantation, embryo development, gastrulation, and the role of different HDAC/KDAC inhibitors during the process of embryogenesis is summarized in the present review article.

A Narrative Inquiry into the Practices of Healthcare Workers' Wellness Program: The SEED Experience in New South Wales, Australia.

The 2019-2020 Australian bushfires followed by the COVID-19 pandemic brought the significant mental health implications of working in healthcare to the fore. The importance of appropriate support services to ensure the resilience and recovery of healthcare workers has been highlighted. In response to healthcare staff experiences during the bushfires, the SEED Wellness Program was created in 2020 in the Illawarra Shoalhaven Local Health District in New South Wales, Australia. SEED used a participant-led design to engage healthcare staff in workplace-based restorative activities. Guided by practice theory, this study aimed to identify and describe SEED wellness practices that supported healthcare staff. Thirty-three healthcare workers participated in focus groups or individual interviews between June 2021 and March 2022. The analysis involved inductive thematic individual and collective exploration of SEED practices, including co-analysis with participants. Eight core practices that supported participants' wellbeing were identified, including responsive and compassionate leading, engaging staff at every stage of the recovery process, creating a sense of connection with others, and collective caring. The study found that workplace wellness initiatives are optimised when they are place-based and grounded in local knowledge, needs, and resources incorporating a collective and supportive team approach. Moreover, to ensure engagement in, and sustainability of these initiatives, both bottom-up and top-down commitment is required.

Identification of potent HDAC 2 inhibitors using E-pharmacophore modelling, structure-based virtual screening and molecular dynamic simulation.

Histone deacetylase 2 (HDAC 2) of class I HDACs plays a major role in embryonic and neural developments. However, HDAC 2 overexpression triggers cell proliferation by diverse mechanisms in cancer. Over the decades, many pan and class-specific inhibitors of HDAC were discovered. Limitations such as toxicity and differential cell localization of each isoform led researchers to hypothesize that isoform selective inhibitors may be relevant to bring about desired effects. In this study, we have employed the PHASE module to develop an e-pharmacophore model and virtually screened four focused libraries of around 300,000 compounds to identify isoform selective HDAC 2 inhibitors. The compounds with phase fitness score greater than or equal to 2.4 were subjected to structure-based virtual screening with HDAC 2. Ten molecules with docking score greater than -12 kcal/mol were chosen for selectivity study, QikProp module (ADME prediction) and dG/bind energy identification. Compound 1A with the best dock score of -13.3 kcal/mol and compound 1I with highest free binding energy, -70.93 kcal/mol, were selected for molecular dynamic simulation studies (40 ns simulation). The results indicated that compound 1I may be a potent and selective HDAC 2 inhibitor. Further, in vitro and in vivo studies are necessary to validate the potency of selected lead molecule and its derivatives.

The SEED Wellness Model: A Workplace Approach to Address Wellbeing Needs of Healthcare Staff During Crisis and Beyond.

Workplace wellness has gained new meaning and significance in the healthcare workforce in the face of the COVID-19 pandemic. Healthcare workers across the world have carried the burden of responding to the public health crisis by having to work under new pressures and constantly changing environments, take on additional shifts, risk their own health and lives, and cope with the ongoing psychological and emotional strain. The purpose of this paper is to articulate a workplace wellness model applied across hospitals in the Illawarra Shoalhaven Local Health District, a regional area in New South Wales, Australia. The description of the development, components, and lessons learned from the SEED Wellness Model illustrates one possible solution about how to provide better care for the staff thus not only preventing staff burnout and turnover, but also creating lasting organizational benefits. The detailed model description can assist in developing a larger and more rigorous evidence-base to improve staff wellness in healthcare settings, both within Australia and internationally.

Histone deacetylase 2 selective inhibitors: A versatile therapeutic strategy as next generation drug target in cancer therapy.

Acetylation and deacetylation of histone and several non-histone proteins are the two important processes amongst the different modes of epigenetic modulation that are involved in regulating cancer initiation and development. Abnormal expression of histone deacetylases (HDACs) is often reported in various types of cancers. Few pan HDAC inhibitors have been approved for use as therapeutic interventions for cancer treatment including vorinostat, belinostat and panobinostat. However, not all the HDAC isoforms are abnormally expressed in certain cancers, such as in the case of, ovarian cancer where overexpression of HDAC1-3, lung cancer where overexpression of HDAC 1 and 3 and gastric cancer where overexpression of HDAC2 is seen. Therefore, pan-inhibition of HDAC is not an efficient way to combat cancer via HDAC inhibition. Hence, isoform-selective HDAC inhibition can be one of the best therapeutic strategies in the treatment of cancer. In this context since aberrant expression of HDAC2 largely contributes to cancer progression by silencing pro-apoptotic protein expressions such as NOXA and APAF1 (caspase 9-activating proteins) and inactivation of tumor suppressor p53, HDAC2 specific inhibitors may help to develop not only the direct targets but also indirect targets that are crucial for tumor development. However, to develop a HDAC2 specific and potent inhibitor, extensive knowledge of its structure and specific functions is essential. The present review updates details on the structural features, physiological functions, and roles of HDAC2 in different types of cancer, emphasizing the challenges and status of the development of HDAC2 selective inhibitors against various types of cancer.

Building workforce well-being capability: The findings of a wellness self-care programme.

AIM: To implement and evaluate a co-designed staff well-being programme. BACKGROUND: Working in health care can be physically and psychologically demanding. The job demands-resources model indicates job resources moderate the impact of job demands on staff well-being. Well-being initiatives introduced by organisations improve staff commitment, and reduce absences and incidents. METHODS: A qualitative descriptive design was applied. In 2019, within an Australian local health district, 232 health care professionals across eight hospitals and two community settings attended a six-week well-being programme, which included a variety of self-care strategies, for example mindfulness. Nine 1-hr focus groups were completed 2-4 weeks post-programme. Data were analysed using thematic analysis to explore participants' thoughts and experiences. RESULTS: Participants experienced joy from workshops and guilt for leaving peers with their workload. Participants developed strong interpersonal relationships with workshop attendees within a 'safe well-being space'. Broader impacts expressed by participants were; learnt coping mechanisms and proactive self-care practices and can be easily embedded into daily routines. Participants shared their 'toolkit' with colleagues, family and friends, positively impacting the well-being of people around them. CONCLUSION: Participants encouraged by their new well-being 'toolkit' engaged with colleagues, better managed stressors and shared learnings. IMPLICATIONS FOR NURSING MANAGEMENT: Building well-being capability within a health organisation requires nursing management to make staff well-being a strategic priority, use a co-design approach and embed coping mechanisms at the grassroots levels.
