Cytochrome c oxidase dependent respiration is essential for T cell activation, proliferation and memory formation.

T cell activation, proliferation, and differentiation are fundamentally driven by shifts in cellular metabolism, with mitochondria playing a central role. Cytochrome c oxidase (COX, complex IV) is a key player in this process, as its activity is crucial for apoptosis, mtDNA maintenance, mitochondrial transcription, and mitochondrial respiration (MR), all of which influence T cell fate and function. Despite its known roles, the specific functions of COX required for T cell activity in vivo remain unclear.

Species-specific variation in mitochondrial genome tandem repeat polymorphisms in hares (Lepus spp., Lagomorpha, Leporidae) provides insight into their evolution.

The non-coding regions of the mitochondrial DNAs (mtDNAs) of hares, rabbits, and pikas (Lagomorpha) contain short (∼20 bp) and long (130-160 bp) tandem repeats, absent in related mammalian orders. In the presented study, we provide in-depth analysis for mountain hare (Lepus timidus) and brown hare (L. europaeus) mtDNA non-coding regions, together with a species- and population-level analysis of tandem repeat variation.

Magnetic domain wall dynamics studied by in-situ Lorentz microscopy with aid of custom-made Hall-effect sensor holder.

We built a custom-made holder with a Hall-effect sensor to measure the single point magnetic flux density inside a transmission electron microscope (TEM, JEM-F200, JEOL). The measurement point is at the same place as the sample inside the TEM. We utilized information collected with the Hall-effect sensor holder to study magnetic domain wall (DW) dynamics by in-situ Lorentz microscopy.

The association of menopausal hormone levels with progression-related biomarkers in multiple sclerosis.

Background: Multiple sclerosis (MS) progression coincides temporally with menopause. However, it remains unclear whether the changes in disease course are related to the changes in reproductive hormone concentrations. We assessed the association of menopausal hormonal levels with progression-related biomarkers of MS and evaluated the changes in serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels during menopausal hormone therapy (MHT) in a prospective baseline-controlled design.

Multi-spectroscopic study of electrochemically-formed oxide-derived gold electrodes.

Oxide-derived metals are produced by reducing an oxide precursor. These materials, including gold, have shown improved catalytic performance over many native metals. The origin of this improvement for gold is not yet understood.

Electronic structure calculations with interpolating tensor product wavelet basis.

We introduce a basis set consisting of three-dimensional Deslauriers-Dubuc wavelets and solve numerically the Schrödinger equations of H and He atoms and molecules H_{2}, H_{2}^{+}, and LiH with Hartree-Fock and density functional theory (DFT) methods. We also compute the 2s and 2p excited states of hydrogen. The Coulomb singularity at the nucleus is handled by using a pseudopotential.

pH dependence of the assembly mechanism and properties of poly(L-lysine) and poly(L-glutamic acid) complexes.

We show by extensive experimental characterization combined with molecular simulations that pH has a major impact on the assembly mechanism and properties of poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) complexes. A combination of dynamic light scattering (DLS) and laser Doppler velocimetry (LDV) is used to assess the complexation, charge state, and other physical characteristics of the complexes, isothermal titration calorimetry (ITC) is used to examine the complexation thermodynamics, and circular dichroism (CD) is used to extract the polypeptides' secondary structure. For enhanced analysis and interpretation of the data, analytical ultracentrifugation (AUC) is used to define the precise molecular weights and solution association of the peptides.

AOX delays the onset of the lethal phenotype in a mouse model of Uqcrh (complex III) disease.

The alternative oxidase, AOX, provides a by-pass of the cytochrome segment of the mitochondrial respiratory chain when the chain is unavailable. AOX is absent from mammals, but AOX from Ciona intestinalis is benign when expressed in mice. Although non-protonmotive, so does not contribute directly to ATP production, it has been shown to modify and in some cases rescue phenotypes of respiratory-chain disease models.

Role of Self-Trapped Excitons in the Broadband Emission of Lead-Free Perovskite-Inspired CuAgBiI.

The perovskite-inspired CuAgBiI (CABI) absorber shows promise for low-toxicity indoor photovoltaics. However, the carrier self-trapping in this material limits its photovoltaic performance. Herein, we examine the self-trapping mechanism in CABI by analyzing the excited-state dynamics of its absorption band at 425 nm, which is responsible for the self-trapped exciton emission, using a combination of photoluminescence and ultrafast transient absorption spectroscopies.

Who buys non-alcoholic beer in Finland? Sociodemographic characteristics and associations with regular beer purchases.

Background: The consumption of non-alcoholic beer and other non-alcoholic and low-alcohol beverages has grown significantly in recent years. Due to a lack of suitable datasets, there have been few studies conducted on the forerunners of the non-alcoholic beer consumption trend. This study examined the associations of sociodemographic characteristics with non-alcoholic beer purchase, and of non-alcoholic beer purchases with regular beer purchases.

Xenotopic expression of alternative oxidase (AOX) to study mechanisms of mitochondrial disease.

The mitochondrial respiratory chain or electron transport chain (ETC) facilitates redox reactions which ultimately lead to the reduction of oxygen to water (respiration). Energy released by this process is used to establish a proton electrochemical gradient which drives ATP formation (oxidative phosphorylation, OXPHOS). It also plays an important role in vital processes beyond ATP formation and cellular metabolism, such as heat production, redox and ion homeostasis.

Associations Between Children's Depressive Symptoms, Life Events, and Family Factors Among School-Aged Children.

Background: About 20-30% of children worldwide report depressive symptoms. This study examined associations between children's depressive symptoms, life events, and family factors.

Methods: Nationally representative data (n = 95,725) were drawn from the 2017 School Health Promotion Study in Finland.

Occupational risk variation of nasopharyngeal cancer in the Nordic countries.

Background: The aim of this study was to estimate occupational risk variation in the incidence of nasopharyngeal cancer (NPC) in a large population-based cohort of the Nordic Occupational Cancer (NOCCA) study.

Methods: This study is based on a cohort of almost 15 million persons from Denmark, Finland, Iceland, Norway and Sweden, with 2898 nasopharyngeal cancer cases diagnosed in 1961-2005. The data on occupations were gathered from population censuses and cancer data from the national cancer registries.

Molecular phenotyping uncovers differences in basic housekeeping functions among closely related species of hares (Lepus spp., Lagomorpha: Leporidae).

Speciation is a fundamental evolutionary process, which results in genetic differentiation of populations and manifests as discrete morphological, physiological and behavioural differences. Each species has travelled its own evolutionary trajectory, influenced by random drift and driven by various types of natural selection, making the association of genetic differences between the species with the phenotypic differences extremely complex to dissect. In the present study, we have used an in vitro model to analyse in depth the genetic and gene regulation differences between fibroblasts of two closely related mammals, the arctic/subarctic mountain hare (Lepus timidus Linnaeus) and the temperate steppe-climate adapted brown hare (Lepus europaeus Pallas).

New approach methods for assessing indoor air toxicity.

Indoor air is typically a mixture of many chemicals at low concentrations without any adverse health effects alone, but in mixtures they may cause toxicity and risks to human health. The aim of this study was by using new approach methods to assess the potential toxicity of indoor air condensates. In specific, different test methods including cyto-and immunotoxicity, skin sensitization and endocrine disruption were applied.

Alleviating Surgeons' Stress through Listening to Natural Sounds in a Half-Encapsulated Rest Space after an Operation: A Pilot, Longitudinal Field Study.

Background: Natural sounds are reportedly restorative, but most research has used one-off experiments conducted in artificial conditions. Research based on field experiments is still in its infancy. This study aimed to generate hypotheses on the restorative effects of listening to natural sounds on surgeons, representing professionals working in stressful conditions.

The transcription factor network of E. coli steers global responses to shifts in RNAP concentration.

The robustness and sensitivity of gene networks to environmental changes is critical for cell survival. How gene networks produce specific, chronologically ordered responses to genome-wide perturbations, while robustly maintaining homeostasis, remains an open question. We analysed if short- and mid-term genome-wide responses to shifts in RNA polymerase (RNAP) concentration are influenced by the known topology and logic of the transcription factor network (TFN) of Escherichia coli.

Negotiations of vulnerability in aging with vision impairment.

Longevity entails a higher prevalence of chronic impairments that often come with aging, such as age-related vision loss (ARLV). Dependence and increasing vulnerabilities contrast sharply with contemporary reductionist models of positive aging, and gradually worsening eyesight exposes older adults with ARLV to situations where idealized models of late life do not fit them. In analyzing semi-structured interviews conducted in Denmark with 40 older adults, aged 55-70 years, with vision loss, this study examines how people in late midlife and early late life negotiate their vulnerability, dependence, and need for help across different contexts.

What physiological role(s) does the alternative oxidase perform in animals?

Although the alternative oxidase, AOX, was known to be widespread in the animal kingdom by 2004, its exact physiological role in animals remains poorly understood. Here we present what evidence has accumulated thus far, indicating that it may play a role in enabling animals to resist various kinds of stress, including toxins, abnormal oxygen or nutrient levels, protein unfolding, dessication and pathogen attack. Much of our knowledge comes from studies in model organisms, where any benefits from exogenously expressed AOX may be masked by its unregulated expression, which may itself be stressful.

Harm as reported by affected others: A population-based cross-sectional Finnish Gambling 2019 study.

This study investigates the prevalence of being an affected other (AO) of a person with problem gambling; and the associations between being an AO and socio-demographics, gambling behaviour, health-related correlates and the amount and type of gambling-related harm (GRH) for the AOs. Furthermore, perspectives of the affected family members (AFMs) and close friends (ACFs) were acknowledged. Cross-sectional, random sample Finnish Gambling population-based survey data (n = 3,994) were collected in 2019.

Classification of emotion categories based on functional connectivity patterns of the human brain.

Neurophysiological and psychological models posit that emotions depend on connections across wide-spread corticolimbic circuits. While previous studies using pattern recognition on neuroimaging data have shown differences between various discrete emotions in brain activity patterns, less is known about the differences in functional connectivity. Thus, we employed multivariate pattern analysis on functional magnetic resonance imaging data (i) to develop a pipeline for applying pattern recognition in functional connectivity data, and (ii) to test whether connectivity patterns differ across emotion categories.

Trends in the Prevalence of Overweight and Obesity Among Women of Reproductive Age.

Background: Information on trends in the prevalence of overweight and obesity and the high-risk groups helps plan health promotion programmes and health policy.
