A WSN and LoRa Hybrid Multimedia Transmission Protocol for Scalar Data and Image Transmission.

The proposed protocol features reliable and fast image transmission while periodically transmitting scalar data without interruption by allowing two networks, a LoRa network and a wireless sensor network, with different transmission characteristics to cooperate. It adopts the RT-LoRa protocol for periodic scalar data transmission and uses a WSN-based pipelined transmission method that leverages single-hop message transmission of a LoRa network for image transmission. Thus, it can not only eliminate the control message overhead for time synchronization, slot scheduling, and path establishment for pipelined image transmission in WSNs but also eliminate interferences within WSNs, such as data collisions and data and message collisions, during pipelined image transmission, thereby enabling high reliability and fast transmission.

A case study of lethal neonatal CPT II deficiency: Novel insights from genetic analysis.

Introduction: Carnitine Palmitoyltransferase II (CPT II) deficiency encompasses a spectrum of disorders, with the lethal neonatal form (LNF) representing the rarest and most severe. While there are numerous gene variants that can cause CPT II deficiency, only 16 variants of these are known to be associated with LNF. This report presents the case of a neonatal male diagnosed with lethal CPT II deficiency, characterized by the presence of two heterogeneous variants.

A New Generation of Multimilliwatt-Class Colloidal Quantum-Dot Lasers at Full Colors.

Colloidal quantum dots (QDs) are attractive gain materials owing to the wide range of accessible colors. However, the existing QD lasers struggle to combine technologically relevant metrics of low threshold and long operating duration with considerable output powers. Here a new class of full-color QD lasers are reported, featuring low threshold, uninterrupted operation for dozens of hours, and multimilliwatt output under quasi-steady-state pumping, by coupling the high-gain QDs with a double-clad pumping scheme.

Extended Surface Bands Enabled Lasing Emission and Wavelength Switch from Sulfur Quantum Dots.

The development of a lasing wavelength switch, particularly from a single inorganic gain material, is challenging but highly demanded for advanced photonics. Nonetheless, all current lasing emission of inorganic gain materials arises from band-edge states, and the inherent fixed bandgap limitation of the band-edge system leads to the inaccessibility of lasing wavelength switching from a single inorganic gain material. Here the realization of a single inorganic gain material-based lasing wavelength switch is reported by proposing an alternative lasing emission strategy, that is, lasing emission from surface gain.

Safety, immunogenicity and efficacy of the self-amplifying mRNA ARCT-154 COVID-19 vaccine: pooled phase 1, 2, 3a and 3b randomized, controlled trials.

Combination of waning immunity and lower effectiveness against new SARS-CoV-2 variants of approved COVID-19 vaccines necessitates new vaccines. We evaluated two doses, 28 days apart, of ARCT-154, a self-amplifying mRNA COVID-19 vaccine, compared with saline placebo in an integrated phase 1/2/3a/3b controlled, observer-blind trial in Vietnamese adults (ClinicalTrial.gov identifier: NCT05012943).

BM-BronchoLC - A rich bronchoscopy dataset for anatomical landmarks and lung cancer lesion recognition.

Flexible bronchoscopy has revolutionized respiratory disease diagnosis. It offers direct visualization and detection of airway abnormalities, including lung cancer lesions. Accurate identification of airway lesions during flexible bronchoscopy plays an important role in the lung cancer diagnosis.

A Novel Efficient Dynamic Throttling Strategy for Blockchain-Based Intrusion Detection Systems in 6G-Enabled VSNs.

Vehicular Social Networks (VSNs) have emerged as a new social interaction paradigm, where vehicles can form social networks on the roads to improve the convenience/safety of passengers. VSNs are part of Vehicle to Everything (V2X) services, which is one of the industrial verticals in the coming sixth generation (6G) networks. The lower latency, higher connection density, and near-100% coverage envisaged in 6G will enable more efficient implementation of VSNs applications.

Shift from a Zero-COVID strategy to a New-normal strategy for controlling SARS-COV-2 infections in Vietnam.

The aim of this study is to analyse the changing patterns in the transmission of COVID-19 in relation to changes in Vietnamese governmental policies, based on epidemiological data and policy actions in a large Vietnamese province, Bac Ninh, in 2021. Data on confirmed cases from January to December 2021 were collected, together with policy documents. There were three distinct periods of the COVID-19 pandemic in Bac Ninh province during 2021.

B cell-specific knockout of AID protects against atherosclerosis.

Antigen-naive IgM-producing B cells are atheroprotective, whereas mature B cells producing class-switched antibodies promote atherosclerosis. Activation-induced cytidine deaminase (AID), which mediates class switch recombination (CSR), would thus be expected to foster atherosclerosis. Yet, AID also plays a major role in the establishment of B cell tolerance.

Evidence-Based Practice in Psychosocial Oncology from the Perspective of Canadian Service Directors.

Evidence-based practices facilitate the effective delivery of psychological services, yet research on the implementation of evidence-based practices in psychosocial oncology (PSO) is scarce. Responding to this gap, we interviewed a diverse sample of 16 directors of Canadian psychosocial oncology services about (a) how evidence-based practices in psychosocial oncology are being implemented in clinical care and how the service quality is monitored and (b) what are barriers and facilitators to evidence-based practice in psychosocial oncology services? Responses were grouped according to three main themes emerging from the data: screening for distress and referral to PSO services, delivery of evidence-based PSO services, and monitoring of PSO services. Our findings highlight facilitators and barriers to evidence-based practice in psychosocial oncology, which were related to the political, social, economic, and geographic contexts.

Lessons for Vietnam on the Use of Digital Technologies to Support Patient-Centered Care in Low- and Middle-Income Countries in the Asia-Pacific Region: Scoping Review.

Background: A rapidly aging population, a shifting disease burden and the ongoing threat of infectious disease outbreaks pose major concerns for Vietnam's health care system. Health disparities are evident in many parts of the country, especially in rural areas, and the population faces inequitable access to patient-centered health care. Vietnam must therefore explore and implement advanced solutions to the provision of patient-centered care, with a view to reducing pressures on the health care system simultaneously.

A case of response to combination treatment with autologous immunotherapy and bevacizumab in advanced non-small cell lung cancer.

Natural killer (NK) cells have developed as a potent tool in cancer immunotherapy. Especially, patients who have failed in the first-line or maintenance treatment received a good response with immunotherapy in association with other approaches. We report the case of a 61-year-old male patient with programmed cell death ligand - 1(PD-L1) expression in advanced non-small cell lung cancer (NSCLC) (stage IV).

Albino tadpoles prefer dark environments compared to wild type.

Tadpoles display preferences for different environments but the sensory modalities that govern these choices are not well understood. Here, we examined light preferences and associated sensory mechanisms of albino and wild-type tadpoles. We found that albino tadpoles spent more time in darker environments compared to the wild type, although they showed no differences in overall activity.

The safety of CAR-T cells and PD-1 antibody combination on an experimental model.

Chimeric antigen receptor (CAR) T cells and PD-1 antibodies (PD-1 Ab) are emergent immunotherapies with unprecedented efficacy. The presence of PD-1 on T cells contributes to hypofunction of CAR-T therapy and inhibition of PD-1 enhances anti-cancer effect of CAR-T cells. Therefore, the combination of CAR-T cells and PD-1 antibody is a promissing strategy for cancer treatment.

Dome-shaped mode lasing from liquid crystals for full-color lasers and high-sensitivity detection.

In this communication, we report a new class of oscillation mode, dome-shaped mode (DSM), in liquid crystal (LC) microlasers. A record high -factor over 24 000 is achieved in LC soft-matter microlasers. We successfully presented a proof-of-concept demonstration of red, green, blue (RGB) LC-DSM microlaser pixels with a 74% broader achievable color gamut than the standard RGB color space.
