RESUMO

Summary: Motivated by the need to parameterize ongoing multicellular simulation research, this paper documents the culmination of a ChatGPT augmented software engineering cycle resulting in an integrated visual platform for efficient cytohistological RNA-seq and bioregulatory network exploration. As contrasted to other systems and synthetic biology tools, BioNexusSentinel was developed de novo to uniquely combine these features. Reactome served as the primary source of remotely accessible biological models, accessible using BioNexusSentinel's novel search engine and REST API requests. The innovative, feature-rich gene expression profiler component was developed to enhance the exploratory experience for the researcher, culminating in the cytohistological RNA-seq explorer based on Human Protein Atlas data. A novel cytohistological classifier would be integrated via pre-processed analysis of the RNA-seq data via R statistical language, providing for useful analytical functionality and good performance for the end-user. Implications of the work span prospects for model orthogonality evaluations, gap identification in network modelling, prototyped automatic kinetics parameterization, and downstream simulation and cellular biological state analysis. This unique computational biology software engineering collaboration with generative natural language processing artificial intelligence was shown to enhance worker productivity, with evident benefits in terms of accelerating coding and machine-human intelligence transfer. Availability and implementation: BioNexusSentinel project releases, with corresponding data and installation instructions, are available at https://github.com/RichardMatzko/BioNexusSentinel.

RESUMO

The elevation of Synthetic Biology from single cells to multicellular simulations would be a significant scale-up. The spatiotemporal behavior of cellular populations has the potential to be prototyped in silico for computer assisted design through ergonomic interfaces. Such a platform would have great practical potential across medicine, industry, research, education and accessible archiving in bioinformatics. Existing Synthetic Biology CAD systems are considered limited regarding population level behavior, and this work explored the in silico challenges posed from biological and computational perspectives. Retaining the connection to Synthetic Biology CAD, an extension of the Infobiotics Workbench Suite was considered, with potential for the integration of genetic regulatory models and/or chemical reaction networks through Next Generation Stochastic Simulator (NGSS) Gillespie algorithms. These were executed using SBML models generated by in-house SBML-Constructor over numerous topologies and benchmarked in association with multicellular simulation layers. Regarding multicellularity, two ground-up multicellular solutions were developed, including the use of Unreal Engine 4 contrasted with CPU multithreading and Blender visualization, resulting in a comparison of real-time versus batch-processed simulations. In conclusion, high-performance computing and client-server architectures could be considered for future works, along with the inclusion of numerous biologically and physically informed features, whilst still pursuing ergonomic solutions.

RESUMO

Insomnia is common but severely underreported and undertreated. One possible reason for this problem is the lack of providers in cognitive behavioral therapy for insomnia (CBT-I). To address this we created CBTIweb.org, an online training platform for providers to learn the basics of sleep, assessing insomnia, and CBT-I. The present study assessed the reach of CBTIweb by examining engagement, knowledge acquisition, and perceived acceptability. Participants who registered for CBTIweb self-reported their practice setting and personal characteristics (i.e. degree, profession, licensure status). Knowledge acquisition was assessed with pre- and post-tests, and provider acceptability was assessed via a survey. In the first three months after launching CBTIweb, 2586 providers registered and 624 of these completed the training within three months of registering. Chi-square tests of independence revealed no differences in completion rates by education or profession, though trainees were more likely to initiate and complete treatment than licensed providers. Paired t tests revealed significant knowledge acquisition, and most providers positively rated the website navigation, content, aesthetics, and understanding of core CBT-I skills. This study demonstrated CBTIweb is an effective platform for training health professionals to be minimally proficient in the gold standard treatment for insomnia disorder.

RESUMO

The psychosocial impact of infertility is affected by cultural factors. In this cross-cultural qualitative study we explored the experience of infertility among six women living in Pakistan and eight living in the UK. Although infertile women in the UK and Pakistan had many shared experiences related to their own desires for motherhood and the hopes of others, they also faced unique psychosocial challenges shaped by cultural context. Based on our findings, we suggest a need for further resources and networks to support women, particularly women living in cultures that allow women few fulfilling social roles other than motherhood.

RESUMO

A 78-year-old man presented with abdominal pain, high International Normalised Ratio and rapidly falling haemoglobin. He had a background of Marfan syndrome and was on warfarin following mechanical aortic valve replacement. Abdominal CT imaging showed haemoperitoneum with a leaking aneurysm of the left gastric artery measuring 10 mm in diameter. The decision whether to reverse his anticoagulation provided a difficult clinical scenario given the risk of thrombosis associated with the mechanical aortic valve. The patient went on to have a successful percutaneous embolisation of the aneurysm using a metallic coil and Onyx. Left gastric artery aneurysms are rare and have a reported mortality of up to 70%. This is the first case of gastric artery aneurysm described in a patient with Marfan syndrome.

RESUMO

The purpose of this study was to assess the impact of emotional intelligence, social support and contextual factors on the general health of infertile women. A sample of involuntarily childless women aged 25-45 living in the UK (n = 148) and Pakistan (n = 164) completed a self-administered questionnaire. Although there were no significant differences in total scores on the General Health Questionnaire (GHQ), British women reported greater anxiety, insomnia and social dysfunction, and Pakistani women reported greater depression and somatic symptoms. Important differences in putative correlates of GHQ scores were found between the samples. British women reported significantly greater emotional satisfaction, greater satisfaction with medical information, greater satisfaction with medical care, and greater actual received support Pakistani women reported greater emotional intelligence. Regression analysis to identify correlates of higher GHQ scores revealed that greater received social support was a common correlate of better GHQ scores among British and Pakistani women. Additional correlates of better GHQ scores among British women were greater emotional intelligence and more emotional satisfaction in their relationships (overall R(2) = 0.41). Additional correlates among Pakistani women were greater education, greater perceived available social support and a nuclear family system rather than an extended family (overall R(2) =0. 40). Results suggest that psychological facets of infertility should be addressed as part of a holistic approach to the care of infertile women. They highlight a need to improve social support and to incorporate emotional intelligence training in therapeutic interventions to improve the psychological well-being of infertile women.

RESUMO

Glufosinate ammonium (GLA) is the active component of herbicides widely used in agriculture, truck farming, or public domains. GLA acts by inhibiting the plant glutamine synthetase (GlnS). It also inhibits mammalian GlnS in vitro and ex vivo. In the central nervous system this enzyme is exclusively localized in glial cells. Whereas acute neurotoxic effects of GLA are well documented, long-term effects during chronic exposure at low doses remain largely undisclosed. In the present work, C57BL/6J mice were treated intraperitoneally with 2.5, 5, and 10 mg/kg of GLA three times a week during 10 weeks. Cerebral magnetic resonance imaging (MRI) experiments were performed at high field (9.4 T) and the images were analyzed with four texture analysis (TA) methods. TA highlighted structural changes in seven brain structures after chronic GLA treatments. Changes are dose dependent and can be seen at a dose as low as 2.5 mg/kg for two areas, namely hippocampus and somatosensorial cortex. Glial fibrillary acidic protein (GFAP) expression in the same seven brain structures and GlnS activity in the hippocampus and cortex areas were also studied. The number of GFAP-positive cells is modified in six out of the seven areas examined. GlnS activity was significantly increased in the hippocampus but not in the cortex. These results indicate some kind of suffering at the cerebral level after chronic GLA treatment. Changes in TA were compared with the modification of the number of GFAP-positive astrocytes in the studied brain areas after GLA treatment. We show that the noninvasive MRI-TA is a sensitive method and we suggest that it would be a very helpful tool that can efficiently contribute to the detection of cerebral alterations in vivo during chronic exposure to xenobiotics.
