Augmentative communication

The emergence of bacterial species is rooted in their inherent potential for continuous evolution and adaptation to an ever-changing ecological landscape. The adaptive capacity of most species frequently resides within the repertoire of genes encoding the secreted proteome (SP), as it serves as a primary interface used to regulate survival/reproduction strategies. Here, by applying evolutionary genomics approaches to metagenomics data, we show that abundant freshwater bacteria exhibit biphasic adaptation states linked to the eco-evolutionary processes governing their genome sizes...

Wound healing is an obvious clinical concern that can be hindered by inadequate angiogenesis, inflammation, and chronic hypoxia. While exosomes derived from adipose tissue-derived stem cells have shown promise in accelerating healing by carrying therapeutic growth factors and microRNAs, intracellular cargo delivery is compromised in hypoxic tissues due to activated hypoxia-induced endocytic recycling. To address this challenge, we have developed a strategy to coat oxygen nanobubbles with exosomes and incorporate them into a polyvinyl alcohol/gelatin hybrid hydrogel...

The present research aimed to document the incidence, clinical signs, haematological, and serum biochemical alterations, as well as electrocardiography and echocardiography findings in 62 buffaloes (selected from a total of 240) infected with Trypanosoma evansi. The study spanned one year, from January 2022 to December 2022. Morphological identification of Trypanosoma evansi was done by the presence of a centrally positioned nucleus with a small sub-terminal kinetoplast at the posterior position through microscopic examination of Giemsa stained peripheral blood smears...

Holographic displays can generate light fields by dynamically modulating the wavefront of a coherent beam of light using a spatial light modulator, promising rich virtual and augmented reality applications. However, the limited spatial resolution of existing dynamic spatial light modulators imposes a tight bound on the diffraction angle. As a result, modern holographic displays possess low étendue, which is the product of the display area and the maximum solid angle of diffracted light. The low étendue forces a sacrifice of either the field-of-view (FOV) or the display size...

Data bias is a major concern in biomedical research, especially when evaluating large-scale observational datasets. It leads to imprecise predictions and inconsistent estimates in standard regression models. We compare the performance of commonly used bias-mitigating approaches (resampling, algorithmic, and post hoc approaches) against a synthetic data-augmentation method that utilizes sequential boosted decision trees to synthesize under-represented groups. The approach is called synthetic minority augmentation (SMA)...

We previously demonstrated a positive relation of secretory phospholipase A2 group IIA (sPLA2-IIA) with circulating high-density lipoprotein cholesterol (HDL-C) in patients with coronary artery disease, and sPLA2-IIA increased cholesterol efflux in THP-1 cells through peroxisome proliferator-activated receptor-γ (PPAR-γ)/liver X receptor α/ATP-binding cassette transporter A1 (ABCA1) signaling pathway. The aim of the present study was to examine the role of sPLA2-IIA over-expression on lipid profile in a transgenic mouse model...

Lip augmentation can correct lip asymmetries, reduce fine lines, define lip shape and Cupid's bow, and add natural fullness to the lips. Achieving a perfect result when injecting lip filler is an art that combines the desire of the patient with the skill of the practitioner and the practitioner's understanding of the surrounding anatomy. It is essential for aesthetic practitioners to prioritize open communication, provide custom-tailored treatments, and have a strong commitment to achieving natural and harmonious results...

Cardiovascular disease (CVD) and cancer are the leading causes of mortality worldwide. Although generally thought of as distinct diseases, the intersectional overlap between CVD and cancer is increasingly evident in both causal and mechanistic relationships. The field of cardio-oncology is largely focused on cardiotoxic effects of cancer therapies (e.g., chemotherapy, radiation). Further, the cumulative effects of cardiotoxic therapy exposure and the prevalence of CVD risk factors in cancer patients leads to long-term morbidity and poor quality of life in this patient population-even when patients are cancer-free...

Efficient communication and collaboration are essential in the operating room for successful and safe surgery. While many technologies are improving various aspects of surgery, communication between attending surgeons, residents, and surgical teams is still limited to verbal interactions that are prone to misunderstandings. Novel modes of communication can increase speed and accuracy, and transform operating rooms. A mixed reality (MR) based gaze sharing application on Microsoft HoloLens 2 headset that can help expert surgeons indicate specific regions, communicate with decreased verbal effort, and guide novices throughout an operation is presented...

Investigations into the compositional model of the Earth, particularly the atypical concentrations of volatile elements within the silicate portion of the early Earth, have attracted significant interest due to their pivotal role in elucidating the planet's evolution and dynamics. To understand the behavior of such volatile elements, an established 'volatility trend' has been used to explain the observed depletion of certain volatile elements. However, elements such as Se and Br remain notably over-depleted in the silicate Earth...

PURPOSE: Biopsies play a crucial role in determining the classification and staging of tumors. Ultrasound is frequently used in this procedure to provide real-time anatomical information. Using augmented reality (AR), surgeons can visualize ultrasound data and spatial navigation information seamlessly integrated with real tissues. This innovation facilitates faster and more precise biopsy operations. METHODS: We have developed an augmented reality biopsy navigation system characterized by low display latency and high accuracy...

Augmented reality has promised a new paradigm in medical education. Multimedia videos are the most preferred assent for augmentation. So, this study aimed to assess the effect of using an augmented reality infographic poster for delivering micro-videos on the knowledge and satisfaction of medical students in cardiology rotation. Sixty students participated in this quasi-experimental study and were allocated to three study groups; namely routine method, routine method plus offline micro-video delivery, and routine method plus micro-video delivery in an augmented reality infographic poster...

Low- and middle-income countries face limited critical care capacity due to constraints in staffing, resources, and technology. "Smart ICUs" that integrate telehealth to augment care delivery, communication, and data integration have the potential to bridge these gaps and reduce preventable morbidity and mortality. While their efficacy has been well validated in adult populations, applications of Smart-ICU services in the neonatal population have not been studied. Neonatal intensive care units (NICUs) in India using a common Smart-NICU platform, developed by CloudPhysician, utilize a hub-and-spokes framework along with locally designed technology to facilitate remote patient care in collaboration with local health systems...

Filariasis, a neglected tropical disease caused by roundworms, is a significant public health concern in many tropical countries. Microscopic examination of blood samples can detect and differentiate parasite species, but it is time consuming and requires expert microscopists, a resource that is not always available. In this context, artificial intelligence (AI) can assist in the diagnosis of this disease by automatically detecting and differentiating microfilariae. In line with the target product profile for lymphatic filariasis as defined by the World Health Organization, we developed an edge AI system running on a smartphone whose camera is aligned with the ocular of an optical microscope that detects and differentiates filarias species in real time without the internet connection...

User-Avatar interaction within augmented reality applications is rapidly increasing in frequency. Applications routinely place users in rooms with other, remote users embodied by photorealistic avatars, or require users to work with an avatar of a remote user to complete a task. During these types of interactions, it is often required to modify or redirect the posture of an avatar to achieve goals such as contact with or pointing at an object or maintaining eye gaze with the local user. A key limitation of modern redirection techniques is successfully preserving body posture, a critical component of nonverbal communication...

INTRODUCTION: Ozone (O3 ) is an air pollutant associated with Alzheimer's disease (AD) risk. The lung-brain axis is implicated in O3 -associated glial and amyloid pathobiology; however, the role of disease-associated astrocytes (DAAs) in this process remains unknown. METHODS: The O3 -induced astrocyte phenotype was characterized in 5xFAD mice by spatial transcriptomics and proteomics. Hmgb1fl/fl LysM-Cre+ mice were used to assess the role of peripheral myeloid cell high mobility group box 1 (HMGB1)...

Seamounts are globally distributed across the oceans and form one of the major oceanic biomes. Here, we utilized combined analyses of bulk metagenome and virome to study viral communities in seamount sediments in the western Pacific Ocean. Phylogenetic analyses and the protein-sharing network demonstrate extensive diversity and previously unknown viral clades. Inference of virus-host linkages uncovers extensive interactions between viruses and dominant prokaryote lineages, and suggests that viruses play significant roles in carbon, sulfur, and nitrogen cycling by compensating or augmenting host metabolisms...

The selection of appropriate vocabulary is a crucial and challenging aspect of augmentative and alternative communication (AAC) intervention. Core vocabulary lists are frequently used to support vocabulary selection for children who require AAC. A vocabulary domain that has garnered limited attention within the AAC literature is relational basic concepts (RBCs). RBCs describe relationships between objects, persons, or situations, and play a pivotal role in language development, communication, and academic success...

Augmentative and alternative communication (AAC) is a core component of speech pathology practice. However, international literature has highlighted that speech language pathologists (SLPs) may not feel confident or competent in this area. Confidence and competence are critical factors in therapy as they can impact the quality-of-service provision. The purpose of this scoping review was to investigate the confidence/competence of SLPs in AAC. A systematic scoping search was conducted using four databases to identify relevant literature...
