OmicsVolcano: software for intuitive visualization and interactive exploration of high-throughput biological dataAdvances in omics technologies have generated exponentially larger volumes of biological data; however, their analyses and interpretation are limited to computationally proficient scientists. We created OmicsVolcano, an interactive open-source software tool to enable visualization and exploration of high-throughput biological data, while highlighting features of interest using a volcano plot interface. In contrast to existing tools, our software and user-interface design allow it to be used without requiring any programming skills to generate high-quality and presentation-ready images.

Ngulluk Moort, Ngulluk Boodja, Ngulluk Wirin (our family, our country, our spirit): An Aboriginal Participatory Action Research study protocolWe are working with the leadership and staff at foster care agencies and community members to provide information about cultural connection, and cultural activity and resources for Aboriginal children living in non-Aboriginal care arrangements.

Stepwise maturation of the peptidyl transferase region of human mitoribosomesMitochondrial ribosomes are specialized for the synthesis of membrane proteins responsible for oxidative phosphorylation. Mammalian mitoribosomes have diverged considerably from the ancestral bacterial ribosomes and feature dramatically reduced ribosomal RNAs. The structural basis of the mammalian mitochondrial ribosome assembly is currently not well understood. Here we present eight distinct assembly intermediates of the human large mitoribosomal subunit involving seven assembly factors.

Barriers and enablers to promoting grandchildren’s physical activity and reducing screen time: a qualitative study with Australian grandparentsWith an increasing number of grandparents providing care to their grandchildren, calls have been made for these caregivers to be considered important stakeholders in encouraging children's engagement in health-promoting behaviors, such as physical activity.

Environmental Determinants of Islet Autoimmunity (ENDIA) longitudinal prospective pregnancy to childhood cohort study of Australian children at risk of type 1 diabetes: parental demographics and birth informationThe Environmental Determinants of Islet Autoimmunity Study is an ongoing Australian prospective cohort study investigating how modifiable prenatal and early-life exposures drive the development of islet autoimmunity and type 1 diabetes in children. In this profile, we describe the cohort's parental demographics, maternal and neonatal outcomes and human leukocyte antigen genotypes.

The Vsr-like protein FASTKD4 regulates the stability and polyadenylation of the MT-ND3 mRNAExpression of the compact mitochondrial genome is regulated by nuclear encoded, mitochondrially localized RNA-binding proteins (RBPs). RBPs regulate the lifecycles of mitochondrial RNAs from transcription to degradation by mediating RNA processing, maturation, stability and translation. The Fas-activated serine/threonine kinase (FASTK) family of RBPs has been shown to regulate and fine-tune discrete aspects of mitochondrial gene expression.

Nurturing families: One year pilot outcomes for a modified Parent Child Assistance Program in AustraliaAlcohol and Other Drug (AOD) exposure during pregnancy is linked to serious adverse child outcomes, including Fetal Alcohol Spectrum Disorder. The Parent-Child Assistance Program (PCAP) supports women with problematic AOD use, who are pregnant or have young children, and are not effectively engaging with services. PCAP has been shown to reduce alcohol exposed pregnancies, promote AOD abstinence, increase employment and family planning and improve child outcomes.

ATFS-1 counteracts mitochondrial DNA damage by promoting repair over transcriptionThe ability to balance conflicting functional demands is critical for ensuring organismal survival. The transcription and repair of the mitochondrial genome requires separate enzymatic activities that can sterically compete, suggesting a life-long trade-off between these two processes.

Harmonized Phenotypes for Anxiety, Depression, and Attention-Deficit Hyperactivity Disorder (ADHD)In multi-cohort consortia, the problem often arises that a phenotype is measured using different questionnaires. This study aimed to harmonize scores based on the Child Behaviour Check List (CBCL) and the Strength and Difficulties Questionnaire (SDQ) for anxiety/depression and ADHD.

Temporal landscape of mitochondrial proteostasis governed by the UPRmtBreakdown of mitochondrial proteostasis activates quality control pathways including the mitochondrial unfolded protein response (UPRmt) and PINK1/Parkin mitophagy. However, beyond the up-regulation of chaperones and proteases, we have a limited understanding of how the UPRmt remodels and restores damaged mitochondrial proteomes.

Investigating Mitochondrial Transcriptomes and RNA Processing Using Circular RNA SequencingTranscriptomic technologies have revolutionized the study of gene expression and RNA biology. Different RNA sequencing methods enable the analyses of diverse species of transcripts, including their abundance, processing, stability, and other specific features. Mitochondrial transcriptomics has benefited from these technologies that have revealed the surprising complexity of its RNAs. Here we describe a method based upon cyclization of mitochondrial RNAs and next generation sequencing to analyze the steady-state levels and sizes of mitochondrial RNAs, their degradation products, as well as their processing intermediates by capturing both 5' and 3' ends of transcripts.

International Consensus Recommendations for the Assessment and Management of Individuals With CDKL5 Deficiency DisorderCDKL5 Deficiency Disorder (CDD) is a rare, X-linked dominant condition that causes a developmental and epileptic encephalopathy (DEE). The incidence is between ~ 1:40,000 and 1:60,000 live births. Pathogenic variants in CDKL5 lead to seizures from infancy and severe neurodevelopmental delay.

No Health without Mental Health: Taking Action to Heal a World in Distress—With People, Places, and Planet ‘in Mind’The unprecedented global rise in mental anguish is closely linked with the erosion of our social fabric, economic and political systems, and to our natural environments. We are facing multiple new large-scale threats to health, safety, and security, with a growing lack of trust in others and in authorities.

Murine bone-derived mesenchymal stem cells undergo molecular changes after a single passage in cultureThe rarity of the mesenchymal stem cell (MSC) population poses a significant challenge for MSC research. Therefore, these cells are often expanded in vitro, prior to use. However, long-term culture has been shown to alter primary MSC properties.

Building a Nyoongar work practice model for Aboriginal youth mental health: prioritising trust, culture and spirit, and new ways of workingMainstream youth mental health services struggle to comprehend the connection between colonisation and service provision for Aboriginal young people. This is the consensus agreed by Aboriginal Elders from Perth, Western Australia and young Aboriginal leaders within their communities.

Mutational rescue of the activity of high-fidelity Cas9 enzymesProgrammable DNA endonucleases derived from bacterial genetic defense systems, exemplified by CRISPR-Cas9, have made it significantly easier to perform genomic modifications in living cells. However, unprogrammed, off-target modifications can have serious consequences, as they often disrupt the function or regulation of non-targeted genes and compromise the safety of therapeutic gene editing applications.

Molecular basis of translation termination at noncanonical stop codons in human mitochondriaThe genetic code that specifies the identity of amino acids incorporated into proteins during protein synthesis is almost universally conserved. Mitochondrial genomes feature deviations from the standard genetic code, including the reassignment of two arginine codons to stop codons.
