Low-Intensity Pulsed Ultrasound Treatment Selectively Stimulates Senescent Cells to Promote SASP Factors for Immune Cell Recruitment.

As emerging therapeutic strategies for aging and age-associated diseases, various biochemical approaches have been developed to selectively remove senescent cells, but how physical stimulus influences senescent cells and its possible application in senolytic therapy has not been reported yet. Here we developed a physical method to selectively stimulate senescent cells via low-intensity pulsed ultrasound (LIPUS) treatment. LIPUS stimulation did not affect the cell cycle, but selectively enhanced secretion of specific cytokines in senescent cells, known as the senescence-associated secretory phenotype (SASP), resulting in enhanced migration of monocytes/macrophages and upregulation of phagocytosis of senescent cells by M1 macrophage.

Super-Resolution Goes Viral: T4 Virus Particles as Versatile 3D-Bio-NanoRulers.

In the burgeoning field of super-resolution fluorescence microscopy, significant efforts are being dedicated to expanding its applications into the 3D domain. Various methodologies have been developed that enable isotropic resolution at the nanometer scale, facilitating the visualization of 3D subcellular structures with unprecedented clarity. Central to this progress is the need for reliable 3D structures that are biologically compatible for validating resolution capabilities.

Clinical Relevance of 'Cap' and 'Track' Development after Recent Small Subcortical Infarct.

Objective: After a recent small subcortical infarct (RSSI), some patients develop perilesional or remote hyperintensities ('caps/tracks') to the index infarct on T2/FLAIR MRI. However, their clinical relevance remains unclear. We investigated the clinicoradiological correlates of 'caps/tracks', and their impact on long-term outcomes following RSSI.

Improving timing resolution of BGO for TOF-PET: a comparative analysis with and without deep learning.

Background: The renewed interest in BGO scintillators for TOF-PET is driven by the improved Cherenkov photon detection with new blue-sensitive SiPMs. However, the slower scintillation light from BGO causes significant time walk with leading edge discrimination (LED), which degrades the coincidence time resolution (CTR). To address this, a time walk correction (TWC) can be done by using the rise time measured with a second threshold.

Co-expression of the RPS6KB1 and PDPK1 genes for production of activated p70S6K1 using bac-to-bac baculovirus expression system.

Background: Ribosomal protein S6 kinase 1 (p70S6K1) is a member of the AGC family of serine/threonine kinases which plays a role in various cellular processes, including protein synthesis, cell growth, and survival. Dysregulation of p70S6K1, characterized by its overexpression and/or hyperactivation, has been implicated in numerous human pathologies, particularly in several types of cancer. Therefore, generating active, recombinant p70S6K1 is critical for investigating its role in cancer biology and for developing novel diagnostic or therapeutic approaches.

Characterisation of intestinal amino acid and oleic acid absorption and their interaction in the Pacific spiny dogfish (Squalus suckleyi).

Elasmobranchs are commonly carnivores and are important in energy transfer across marine ecosystems. Despite this, relatively few studies have examined the physiological underpinnings of nutrient acquisition in these animals. Here, we investigated the mechanisms of uptake at the spiral valve intestine for two representative amino acids (-alanine, -leucine) and one representative fatty acid (oleic acid), each common to the diet of a carnivore, the Pacific spiny dogfish (Squalus suckleyi).

Association of Total Mortality and Cardiovascular Endpoints With the Timing of the First and Second Systolic Peak of the Aortic Pulse Wave.

Prognostic significance of the timing in the cardiac cycle of the first (TP1) and second (TP2) systolic peak of the central aortic pulse wave is ill-defined. Incidence rates and standardized multivariable-adjusted hazard ratios (HRs) of adverse health outcomes associated with TP1 and TP2, estimated by the SphygmoCor software, were assessed in the International Database of Central Arterial Properties for Risk Stratification (IDCARS) (n = 5529). Model refinement was assessed by the integrated discrimination (ID) and net reclassification (NR) improvement.

The Potential of Poetry in Mental Health Nurse Pre-registration Education.

This paper examines the potential of poetry as a resource within mental health nurse pre-registration education. There has long been a debate as to whether the art or the science of nursing should be foregrounded within pre-registration education, especially in the UK within recent years as the latest Nursing and Midwifery Council's standards of pre-registration education appear to have shifted the focus towards the acquisition of skills, giving less consideration to the holistic transformatory process of education. The paper uses the conceptualisation of education by Beista, who proposes that education can be considered in relation to the three domains of qualification, socialisation and subjectification.

Effects of Intrauterine Isoproterenol Administration on Ovarian Follicular Development in Cows.

Background: Isoproterenol (ISO) is a nonselective beta-adrenergic receptor agonist known for its vasodilatory effects. This experiment aims to investigate whether intrauterine ISO administration could alter vascular indices and follicular development in postpartum Holstein cows.

Objectives: The objectives are to evaluate the effects of intrauterine ISO administration on vascular changes and its impact on follicular development compared to placebo groups.

Effects of an intervention on immigrant parents' knowledge and attitudes toward their children's oral health: A cluster randomized trial in Norway.

There are no interventional studies on the oral health of immigrant children in Norway. This study aimed to assess the effectiveness of a culturally adapted oral health intervention for parental knowledge, attitude to oral hygiene, attitude to diet, and indulgence (permissiveness toward oral hygiene and sugar intake) concerning their children's oral health. A cluster randomized control trial, including immigrant parents of newborns, was conducted at seven health centers in Bergen (Norway) involving a 2-session one-to-one motivational interviews, toothbrushing demonstrations and pamphlets in the participants' native languages at baseline and after 6 months.

Therapeutic Scrutiny of Lentinus polychrous with Attention to Its Antioxidant, Antimicrobial, and Anticancer Attributes.

Mushrooms, being a source of therapeutically active compounds, are of great interest to researchers due to their historical usage in traditional therapies and the significant role that natural products have played in the development of contemporary medications. Lentinus polychrous is one underutilized mushroom species collected from the laterites of West Bengal, India. Our study aims toward its taxonomic validation, deciphering the secondary metabolic fingerprint, and testing its efficiency in countering many clinical issues, including oxidative stress, growing microbial drug resistance, and cancer.

Effects of Exergame Training on Executive Function and Heart Rate Variability in Middle-Aged and Older Adults: A Randomized Controlled Study.

Exergame has become widely popular and offers great levels of cognitive demands, thus may facilitate cognitive benefits. In addition, researchers have proposed that cardiac autonomic function, assessed via heart rate variability (HRV), is associated with cognitive executive function. However, few exergame training studies have investigated this relationship.

What a tangled web we weave: crosstalk between JAK-STAT and other signalling pathways during development in Drosophila.

The Janus kinase-signal transducer and activator of transcription (JAK-STAT) signalling pathway is a key player in animal development and physiology. Although it functions in a variety of processes, the net output of JAK-STAT signalling depends on its spatiotemporal activation, as well as extensive crosstalk with other signalling pathways. Drosophila, with its relatively simple signal transduction pathways and plethora of genetic analysis tools, is an ideal system for dissecting JAK-STAT signalling interactions.

The bright and dark side of blue-enriched light on sleep and activity in older adults.

Low indoor light in urban housing can disrupt health and wellbeing, especially in older adults who experience reduced light sensitivity and sleep/circadian disruptions with natural aging. While controlled studies suggest that enhancing indoor lighting may alleviate the negative effects of reduced light sensitivity, evidence for this to be effective in the real world is lacking. This study investigates the effects of two light conditions on actigraphic rest-activity rhythms and subjective sleep in healthy older adults (≥ 60 years) living at home.

Action of the Euclidean versus projective group on an agent's internal space in curiosity driven exploration.

According to the Projective Consciousness Model (PCM), in human spatial awareness, 3-dimensional projective geometry structures information integration and action planning through perspective taking within an internal representation space. The way different perspectives are related to and transform a world model defines a specific perception and imagination scheme. In mathematics, such a collection of transformations corresponds to a 'group', whose 'actions' characterize the geometry of a space.

Green Assessment of Sensitive Spectrofluorimetric Methods for Simultaneous Estimation of Formoterol Fumarate and Fluticasone Propionate Using a Micelle-Mediated Approach.

Highly sensitive spectrofluorimetric methods were developed for the quantitative estimation of formoterol fumarate dihydrate (FFD) and fluticasone propionate (FP) in both authentic raw materials and marketed dosage forms using a micellar-enhanced spectrofluorimetric approach. The proposed methods are based on the determination of FP in the presence of FFD using the first derivative emission spectrofluorimetry. The peak amplitude of the emission spectra of the formed micellar fluorescence was measured at 465 nm after excitation at 236 nm (λ max of FP).

Enhanced sensitivity and scalability with a Chip-Tip workflow enables deep single-cell proteomics.

Single-cell proteomics (SCP) promises to revolutionize biomedicine by providing an unparalleled view of the proteome in individual cells. Here, we present a high-sensitivity SCP workflow named Chip-Tip, identifying >5,000 proteins in individual HeLa cells. It also facilitated direct detection of post-translational modifications in single cells, making the need for specific post-translational modification-enrichment unnecessary.

Xylaria iriomotensis sp. nov. from termite nests and notes on X. angulosa.

Background: Fungus gardens of the termite Odontotermes formosanus, excavated from Iriomote Island, Okinawa Prefecture, Japan, were subsequently incubated under laboratory conditions. A Xylaria species emerging from these fungus gardens was initially identified as X. angulosa, a species originally described from North Sulawesi, Indonesia.

Pregnancy entails a U-shaped trajectory in human brain structure linked to hormones and maternal attachment.

Growing evidence places the gestational period as a unique moment of heightened neuroplasticity in adult life. In this longitudinal study spanning pre, during, and post pregnancy, we unveil a U-shaped trajectory in gray matter (GM) volume, which dips in late pregnancy and partially recovers during postpartum. These changes are most prominent in brain regions associated with the Default Mode and Frontoparietal Network.

A Radiograph Dataset for the Classification, Localization, and Segmentation of Primary Bone Tumors.

Primary malignant bone tumors are the third highest cause of cancer-related mortality among patients under the age of 20. X-ray scan is the primary tool for detecting bone tumors. However, due to the varying morphologies of bone tumors, it is challenging for radiologists to make a definitive diagnosis based on radiographs.

Frequency-bin-encoded entanglement-based quantum key distribution in a reconfigurable frequency-multiplexed network.

Large-scale quantum networks require dynamic and resource-efficient solutions to reduce system complexity with maintained security and performance to support growing number of users over large distances. Current encoding schemes including time-bin, polarization, and orbital angular momentum, suffer from the lack of reconfigurability and thus scalability issues. Here, we demonstrate the first-time implementation of frequency-bin-encoded entanglement-based quantum key distribution and a reconfigurable distribution of entanglement using frequency-bin encoding.

Patient safety is our business! Staff perspectives on implementing hospital falls prevention education.

Providing patients with falls prevention education reduces falls in hospitals, yet there is limited research on what influences successful implementation at the staff, ward and hospital levels. We engaged hospital-based health professionals to identify multi-level barriers and enablers to patient falls education that could influence the implementation of a Safe Recovery program. Purposive sampling was used to recruit hospital staff (n = 40) for focus groups and one-on-one interviews.
