Surface-engineered LNPs, propelled by clinical successes like patisiran and mRNA vaccines, enable targeted nucleic acid delivery via ligands (antibodies, peptides) and conjugation chemistries (click reactions). These LNPs target organs (liver, lungs) and cells (immune, brain), advancing gene therapy and vaccines. Key challenges—batch reproducibility, ligand stability, scalable production—must be resolved to accelerate clinical translation and expand applications to protein/small-molecule delivery.

This protocol establishes the chorioallantoic membrane (CAM) model in avian embryos to investigate migrasome-mediated angiogenesis mechanisms. Key methodologies include the CAM nylon mesh assay and ex vivo sprouting assay for quantifying vascular growth, alongside migrasome isolation, labeling, and targeted delivery. CRISPR-generated T4-KO-mCherry-KI embryos enable functional analysis of migrasome dynamics in real-time angiogenesis. The CAM's high vascularity and accessibility allow parallel assessment of pro-/anti-angiogenic factors and migrasome-cell interaction mapping. By integrating genetic editing and migrasome manipulation, this platform bridges migrasome biology with developmental angiogenesis, offering a scalable tool for mechanistic and therapeutic exploration.

This review focuses on the unique characteristics of mitochondrial nucleoids in mammalian cells, highlighting their semi-autonomous nature and the role of phase separation in their organization and function. It draws parallels to the well-established role of phase separation in nuclear architecture and gene regulation.

A scientific breakthrough at Tel Aviv University: A world-first study shows an acoustic interaction between plants and insects. In this study, the team focused on female moths and found that they make a critical decision—where to lay their eggs—based on sounds emitted by nearby plants. When plants emitted distress sounds, the female moths preferred healthy plants that were not emitting such sounds. These sounds are ultrasonic, beyond the hearing range of the human ear, but moths can hear them.

Morphine is a potent opioid medicine utilized for the management of moderate to severe pain, particularly in palliative care, post-surgical recovery, and cancer treatment. But, it carries risks of addiction liability and respiratory depression. Thus, aim of the review was designed to insights into morphine: extraction, structural characterization, and pharmacological properties. A literature survey on scientific journals, books as well as electronic sources was performed for the content. This review delves into the multifaceted aspects of morphine, one of the most well-known opiate analgesics, focusing on its extraction, structural characterization, and pharmacological properties. The pharmacological profile of morphine is critically examined, highlighting its mechanisms of action, including its interactions with opioid receptors, and the resulting physiological effects. Also, the therapeutic applications of morphine is discussed in pain management, its potential for addiction, and the emergence of tolerance. By synthesizing current knowledge, this review provides a comprehensive understanding of morphine’s significance in medicine and its implications for future pharmacological developments.

Dear Editor,

Nipah virus (NiV) poses a significant threat to global health security due to its high fatality rate and the possibility of human-to-human transmission.1 This zoonotic virus can cause serious effect in both animals and humans.2 Although there are currently no approved vaccines or therapeutics for NiV, there have been promising advances in vaccine development in recent years, bringing us one step closer to curbing the impact of this deadly disease. NiV outbreaks have been reported in several countries in southern Asian countries in support of their statement, outbreaks are taken place annually in Bangladesh.3 The main route of transmission to human is through contact with infected animals, particularly, flying fox (Pteropus) natural reservoir of the virus. However, raising concerns about the pandemic potential of the virus and their impact on human-to-human transmission has also been documented.4

Objective: To retrospectively analyze the expression and significance of γδ T cells and lymphocyte subsets in peripheral blood on patients with multiple myeloma (MM).

Methods: Fifty-five patients with multiple myeloma admitted to Yangpu Hospital Affiliated to Tongji University from January 2022 to August 2023 were selected as the disease group, and were categorized into stage I group, stage II group and stage III group according to the International Staging System (ISS) of multiple myeloma. All included patients were consecutive visits. Another 30 cases of healthy people with physical examination were selected as the control group. Flow cytometry was used to detect the γδ T cells and lymphocyte subsets in the peripheral blood of the subjects. After clinical indicators of patients and healthy controls were collected, the statistical analysis was conducted.

Results: Compared with the control group, the percentage of γδ T cells and CD8+ T cells in the disease group were higher, while, the absolute numbers of total peripheral blood lymphocytes (LYMT) and CD19+ B cells, percentage of CD19+ B cells, CD3+ T cells, CD4+ T cells were lower (P​<​0.05). The percentage of γδ T cells (P​<​0.001), the percentage of CD19+ B cells (P​=​0.003), the absolute number of CD3+ T cells (P​=​0.010), the absolute number of CD8+ T cells (P​=​0.002) were the significant influential factors of MM. γδ T cells (P​=​0.004), neutrophils (P​<​0.001), neutrophil to lymphocyte ratio (P​=​0.003), and white blood cell count (P​<​0.001) were statistically different in different stages. ROC curve suggested that the area under the curve of the percentage of γδ T cells in predicting the MM were 0.973 (P​<​0.001) which had certain diagnostic value.

Conclusions: γδ T cells and lymphocyte subsets (CD8+ T cells, CD19+ B cells, CD3+ T cells, etc.) in patients with newly diagnosis of MM can reflect the immune function of the patient’s organism, which is a key factor of MM. γδ T cells influence the staging of MM patients, and also have certain diagnostic value.

The recent global outbreak of monkeypox (mpox) has underscored the urgent need for rapid, accurate, and accessible diagnostic tools. The unprecedented spread of mpox beyond its endemic regions has highlighted significant gaps in our preparedness for emerging infectious diseases, particularly in diagnostics. Traditional methods like polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), while accurate, often require sophisticated equipment and trained personnel, leading to potential delays in diagnosis and disease management. In response, the development of point-of-care (POC) biosensors has emerged as a critical area of research, offering the promise of rapid, on-site detection with minimal resource requirements. This article explores various biosensing technologies, including CRISPR-based systems, electrochemical sensors, optical biosensors, and microfluidic devices. We discuss the principles behind these technologies, their performance characteristics, advantages, limitations, and potential for real-world application. By leveraging the current state of knowledge, this article provides a comprehensive overview of the latest developments in POC biosensors for mpox detection to enhance cognizance among researchers, healthcare professionals, and policymakers about the latest advancements and opportunities in this critical area of public health, contributing to enhanced global health security and preparedness against mpox and other emerging infectious diseases.
