The expansion of distributed generation and erratic loads create many challenges for electricity distribution networks (DN), like grid congestion and load unbalance. Technological advances in recent years have made the use of electric vehicles (EVs) more economical and justified for network connection. The use of smart EVs in the network scale, in addition to the peak shedding, if it is used in a single phase, it can also lead to the improvement of load unbalance.

Concrete, as a cornerstone of modern construction, heavily relies on the quality of its constituent materials, particularly aggregates. Among the critical factors contributing to high-quality concrete are proper gradation, absence of clay particles, and angular shape of aggregates. Adhering to these standards typically results in concrete with superior strength.

Article Synopsis
  • Extrachromosomal circular DNA (ecDNA) is commonly found in various human cancers, particularly in oropharyngeal cancer linked to the human papillomavirus (HPV), but its role in cancer development is not fully understood.
  • Researchers studied the epigenetic characteristics of hybrid ecDNA in HPV-positive oropharyngeal cancer cell lines and tumor models, discovering that HPV oncogenes E6/E7 are associated with unique enhancer regions.
  • By using targeted therapies, such as CRISPR interference and specific inhibitors, they were able to decrease E6/E7 gene expression and inhibit tumor growth, highlighting the potential for new treatments that target ecDNA-driven cancer biology.

Living with a diverse array of predators provides a significant challenge for prey to learn and retain information about each predator they encounter. Consequently, some prey respond to novel predators because they have previous experience with a perceptually similar predator species, a phenomenon known as generalization of predator recognition. However, it remains unknown whether prey can generalize learned responses across ontogenetic stages of predators.

Recently, modifying bacterial cellulose (BC) by compositing it with other nano-biomaterials has become inevitable to achieve its desired properties in drug delivery. To address this, our study endeavors to utilize an in-situ fabrication method for the creation of a multifunctional BC/gelatin (BC/Gel) platform reinforced with carboxylic multi-walled carbon nanotubes (cMWCNTs) as a sustainable delivery model of biomolecules. Incipiently, cMWCNTs were loaded with human serum albumin (HSA) as a drug model, with an optimized nanoparticle-to-protein ratio of 1:5 and loading efficiency of 90.

Multiple myeloma is a type of malignant neoplasia whose treatment has changed over the past decade. This study aimed to investigate the effects of combination of Adenovector-carrying interleukin-24 and herpes simplex virus 1 thymidine kinase/ganciclovir on tumor growth, autophagy, and unfolded protein response mechanisms in mouse model of multiple myeloma. Six groups of mice, including Ad-HSV-tk/GCV, Ad-IL-24, Ad-HSV-tk/IL-24, Ad-GFP, and positive and negative controls, were investigated, and each group was injected every 72 h.

Long non-coding RNA [LncRNA] dysregulation has been seen in many human cancers, including several kinds of leukemia, which is still a fatal disease with a poor prognosis. LncRNAs have been demonstrated to function as tumor suppressors or oncogenes in leukemia. This study covers current research findings on the role of lncRNAs in the prognosis and diagnosis of leukemia.

Article Synopsis
  • - The study investigates three therapeutic HPV vaccine candidates using a recombinant protein, tumor cell lysate, and engineered exosomes that incorporate a fusion protein (Hsp27-E7), aiming to treat existing HPV-related lesions and cancers.
  • - The vaccines were tested in mice, demonstrating a strong immune response and a 75% survival rate across all three vaccine types, indicating their effectiveness in preventing tumor development.
  • - Among the candidates, the engineered exosome-based vaccine (Exo-Hsp27-E7) showed the best results in terms of immune response and safety, making it a promising option for future HPV vaccinations.

Salivary glands have essential roles in maintaining oral health, mastication, taste and speech, by secreting saliva. Salivary glands are composed of several types of cells, and each cell type is predicted to be involved in the carcinogenesis of different types of cancers including adenoid cystic carcinoma (ACC), acinic cell carcinoma (AciCC), salivary duct carcinoma (SDC), myoepithelial carcinoma (MECA) and other histology. In our study, we performed single nucleus RNA-seq on three human salivary gland samples to clarify the gene expression profile of each complex cellular component of the salivary glands and related these expression patterns to expression found in salivary gland cancers (SGC) to infer cell of origin.

Purpose: Adolescents living in protracted conflict areas have mostly been perceived as passive recipients of the impact of events in their surroundings who are rarely considered agents of social transformation. But a growing body of research on adolescents' psychological development indicates that adolescents actively perceive concepts like peace and their roles and responsibilities toward creating conditions for peace. Applying the Phenomenological Variant of Ecological Systems Theory, this study focuses on understanding how adolescents from Afghanistan with lifelong exposure to intractable conflict conceptualize peace.

To relieve the limitations of the human papillomavirus (HPV) vaccines based on L1 capsid protein, vaccine formulations based on RG1 epitope of HPV L2 using various built-in adjuvants are under study. Herein, we describe design and construction of a rejoined peptide (RP) harboring HPV16 RG1 epitope fused to TLR4/5 agonists and a tetanus toxoid epitope, which were linked by the (GGGS) linker in tandem. In silico analyses indicated the proper physicochemical, immunogenic and safety profile of the RP.

Article Synopsis
  • HPV-associated oropharynx carcinoma (HPVOPC) tumors exhibit low mutational burden, and studying other alterations like DNA methylation, alternative splicing, and copy number variation can reveal more about how this cancer develops.
  • Research identified that methylation changes had the strongest connection to gene expression networks, notably within G protein-coupled receptor (GPCR) pathways, including immune-related signals from CXCR3 cytokines.
  • In vivo studies showed that blocking the CXCR3 receptor slowed tumor growth in mice lacking an immune response, indicating that while the CXCR3 axis can promote tumor growth, it can also be influenced by the immune system, highlighting the complexity of targeting this pathway in treatment.
