Re-Cellularised Kidney Scaffold for Chikungunya Virus Propagation: A Novel Approach.

BACKGROUND: Re-emerging viral attacks are catastrophic for health and economy. It is crucial to grasp the viral life cycle, replication and mutation policies and attack strategies. It is also absolute to fathom the cost-efficient antiviral remedies earliest possible. METHODS: We propose to use a lab-grown organ (re-cellularized scaffold of sheep kidney) for viral culture and understand its interaction with extra-cellular matrices of the host tissue. RESULTS: Our findings showed that the chikungunya virus (CHIKV) could be better replicated in tissue-engineered bio models than cell culture. A

Targeted Drug Delivery and Theranostic Strategies in Malignant Lymphomas.

Malignant lymphomas represent the most common type of hematologic malignancies. The first clinically approved TDD modalities in lymphoma patients were anti-CD20 radioimmunoconjugates (RIT) 131I-tositumomab and 90Y-ibritumomab-tiuxetan. The later clinical success of the first approved antibody-drug conjugate (ADC) for the treatment of lymphomas, anti-CD30 brentuximab vedotin, paved the path for the preclinical development and clinical testing of several other ADCs, including polatuzumab vedotin and loncastuximab tesirine. Other modalities of TDD are based on new formulations of "old" cytostatic

Структура-ориентированное исследование ДНК-аптамера, целевого PTK7, выявляет сложную 3D-составляющую, направляющую оптимизацию функции.

DNA аптамеры вышли в качестве новых молекулярных инструментов в терапевтической и диагностической медицине благодаря своей высокой аффинности и специфичности к белковым целям, что определяется их способностью сворачиваться в отличительные трехмерные (3D) структуры. Однако при проектировании и моделировании аптамеров часто игнорируются тонкие атомные взаимодействия, формирующие 3D структуры, что приводит к неэффективной оптимизации функциональных свойств. Проблемы сохраняются при определении высокоразрешающих структур комплексов аптамер-белок. Кроме того, экспериментально определенные 3D структ

Human isoprenoid synthase enzymes as therapeutic targets.

In the human body, the complex biochemical network known as the mevalonate pathway is responsible for the biosynthesis of all isoprenoids, which consists of a vast array of metabolites that are vital for proper cellular functions. Two key isoprenoids, farnesyl pyrophosphate (FPP) and geranylgeranyl pyrophosphate (GGPP) are responsible for the post-translational prenylation of small GTP-binding proteins, and serve as the biosynthetic precursors to numerous other biomolecules. The down-stream metabolite of FPP and GGPP is squalene, the precursor to steroids, bile acids, lipoproteins, and vitamin

ЦЕЛИ: Данное исследование было направлено на изучение воздействия Сп3 на ТХ17 в клетках EAE и ле

Artificial Intelligence in the Management of Hereditary and Acquired Hemophilia: From Genomics to Treatment Optimization.

Hemophilia, an X-linked bleeding disorder, is characterized by a deficiency in coagulation factors. It manifests as spontaneous bleeding, leading to severe complications if not properly managed. In contrast, acquired hemophilia is an autoimmune condition marked by the development of inhibitory antibodies against coagulation factors. Both forms present significant diagnostic and therapeutic challenges, highlighting the need for advanced genetic, molecular, laboratory, and clinical assessments. Recent advances in artificial intelligence have opened new avenues for the management of hemophilia. M

Current landscape and future directions of targeted-alpha-therapy for glioblastoma treatment.

Glioblastoma (GB) is the most aggressive malignancy of the central nervous system. Despite two decades of intensive research since the establishment of the standard of care, emerging strategies have yet to produce consistent satisfactory outcomes. Because of its specific localisation and intricate characteristics, GB is a uniquely regulated solid tumour with a strong resistance to therapy. Advances in targeted radionuclide therapy (TRT), particularly with the introduction of a-emitting radionuclides, have unveiled potential avenues for the management of GB.

Application of Nanoparticles for Magnetic Hyperthermia for Cancer Treatment-The Current State of Knowledge.

Hyperthermia (HT) is an anti-cancer therapy commonly used with radio and chemotherapies based on applying heat (39-45 °C) to inhibit tumor growth. However, controlling heat towards tumors and not normal tissues is challenging. Therefore, nanoparticles (NPs) are used in HT to apply heat only to tumor tissues to induce DNA damage and the expression of heat shock proteins, which eventually result in apoptosis. The aim of this review article is to summarize recent advancements in HT with the use of magnetic NPs to locally increase temperature and promote cell death. In addition, the recent develop

Calcium Phosphate Ceramics Can Prevent Bisphosphonate-Related Osteonecrosis of the Jaw.

Bisphosphonate-associated osteonecrosis of the jaw (BRONJ), a post-surgical non-healing wound condition, is one of the most common side effects in patients treated with nitrogen-containing bisphosphonates. Its physiopathology has been related with suppression of bone turnover, of soft tissue healing and infection. Biphasic calcium phosphates (BCP) are used as a drug delivery vehicle and as a bone substitute in surgical wounds. Due to their capacity to adsorb zoledronate, it was hypothesized these compounds might have a protective effect on the soft tissues in BRONJ wounds. To address this hypo
