Mesenchymal Stem Cell Therapy for Neurological Complications of Prematurity: A Narrative Review.

Background: Preterm birth is a leading cause of neonatal mortality and long-term disability worldwide. Injury in premature infants is demonstrated by disrupted organ development from inflammation, oxidative stress, hypoxia, and impaired vascular maturation. Current therapies largely provide supportive care and do not directly promote tissue regeneration. Mesenchymal stem cell (MSC)-based therapies have emerged as a potential strategy to enhance endogenous repair across organ systems commonly affected by prematurity. Results: Evidence indicates that MSCs exert therapeutic effects primarily thro

Диагностический потенциал двух новых биомаркеров для спектра нейромиелита оптики и множественной склероза

Фон: В настоящее время нет тестов, которые могут однозначно диагностировать и различать нейромиелит оптического спектра (NMOSD) от множественной скlerоза (МС). Методы: Сначала были использованы протеомные исследования спинно-мозговой жидкости (ССФ) для выявления новых биомаркеров, которые различают NMOSD от МС в группах из 10 пациентов с МС и 10 пациентов с NMOSD. Далее биомаркеры были проверены с помощью метода связывания иммунно-электрофоретической реакции и образцов ССФ и сыворотки от 20 пациентов с МС, 20 пациентов с NMOSD, 20 непатологических нейрологических контролей и 20 здоровых контро

7-day longitudinal proteomics of critically ill patients: a pilot study.

An adult's health, indicated by measurable parameters, is stable over time. With the exception of circadian rhythms, variability in these parameters typically does not exceed 20%. In this pilot study, we looked into the stability of proteome in intensive care unit (ICU) patients. This was a single-center, prospective, observational pilot study of blood plasma from adult ICU patients with statistically heterogeneous patterns of clinically observed parameters. Eight week-long batches from seven patients (one patient participated twice) were analyzed by means of bottom-up proteomics. The data wer

However, the presence of NETs in both compartments ( 83 ) versus exclusively in the vasculature ( 82 ) remains a subject of debate. …

Low-level laser therapy prevents medication-related osteonecrosis of the jaw-like lesions via IL-1RA-mediated primary gingival wound healing.

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a serious debilitating disease caused by anti-resorption and anti-angiogenesis drugs, significantly affecting patients' quality of life. Recent studies suggested that primary gingival wound healing may effectively prevent the development of MRONJ. This study aimed to evaluate the effects of low-level light therapy (LLLT) on promoting gingival wound healing in extraction sockets of MRONJ-like mice and preventing the occurrence of MRONJ. Furthermore, we explored underlying mechanisms. METHODS: Mice were randomly divided into the

Роль NLRP3 инфламасома в множестве склероза: патогенез и фармакологическое применение.

Множественный склероз (MS) широко признается в качестве хронического провокационного аутоиммунного расстройства, характеризующегося демиэлизацией центральной нервной системы (КНС) и нейродегенерацией. Гиперактивация иммунной и подстрекательской реакции признается в качестве ключевого фактора, способствующего патогенезу и прогрессированию MS. Среди различных иммунных и подстрекательских реакций исследователи все больше концентрируют внимание на воспалении — комплексе белков. Запуск и активация воспламенения неразрывно связаны с началом НР. В частности, NLRP3 воспаляет, наиболее широко изучавший

Tumor microenvironment targeted nano-drug delivery systems for multidrug resistant tumor therapy.

In recent years, nano-drug delivery systems (Nano-DDS) that target the tumor microenvironment (TME) to overcome multidrug resistance (MDR) have become a research hotspot in the field of cancer therapy. By precisely targeting the TME and regulating its unique pathological features, such as hypoxia, weakly acidic pH, and abnormally expressed proteins, etc., these Nano-DDS enable effective delivery of therapeutic agents and reversal of MDR. This scientific research community is increasing its investment in the development of diversified systems and exploring their anti-drug resistance potential.

Смолдинг нейроинфламмации в прогрессивном множественном склерозе: механизмы, визуальные биомаркеры и терапевтические возможности.

Прогрессивный множественный склероз (MS) по-прежнему является серьезной терапевтической проблемой, поскольку инвалидность часто продолжает накапливаться, несмотря на эффективный контроль за рецидивами и новыми головными провокационными повреждениями. Эта диссоциация говорит о том, что прогресс определяется не только острым воспалением, но и отдельным процессом, который все чаще называется задушающим нейро-воспалением. Последние данные подтверждают, что хронические активные повреждения являются важным, но не эксклюзивным патологическим субстратом этого процесса. Эти повреждения характеризуются

Prevention of venous thromboembolism in ambulatory patients with cancer.

Patients with cancer are at high risk of venous thromboembolic events, and this risk can be further increased in patients with certain cancer types and by cancer treatments. Guidelines on the prevention of cancer-associated thrombosis (CAT) recommend thromboprophylaxis for hospitalised patients; however, this is not routinely recommended for ambulatory patients receiving chemotherapy and is limited to specified high-risk patients. Identification of the ambulatory patients at risk of CAT who would most benefit from anticoagulant therapy is therefore critical to reduce the incidence of this comp

Novel Combinatorial Approaches to Tackle the Immunosuppressive Microenvironment of Prostate Cancer.

Prostate cancer (PCa) is the second-most common cancer in men worldwide and treatment options for patients with advanced or aggressive prostate cancer or recurrent disease continue to be of limited success and are rarely curative. Despite immune checkpoint blockade (ICB) efficacy in some melanoma, lung, kidney and breast cancers, immunotherapy efforts have been remarkably unsuccessful in PCa. One hypothesis behind this lack of efficacy is the generation of a distinctly immunosuppressive prostate tumor microenvironment (TME) by regulatory T cells, MDSCs, and type 2 macrophages which have been i

Interplay Between Poly(ADP-ribosyl)ation and Specific Inner Cellular Events That Suggest Combination Strategies for Overcoming PARP Inhibitor Resistance.

Therapeutic resistance remains a major obstacle to durable cancer control, with functional reprogramming of the DNA damage response (DDR) network playing a central role. The poly(ADP-ribose) polymerase (PARP) family, particularly PARP1 and PARP2, is crucial for maintaining genomic integrity. By exploiting synthetic lethality, PARP inhibitors (PARPi) selectively target tumors with homologous recombination deficiency (HRD) and are integral to precision therapy in ovarian, breast, and prostate cancers. However, over 40% of patients with BRCA1/2 alterations develop resistance, and patient eligibil

The burden and predictors of venous thromboembolic diseases in patients with multiple primary malignancies.

BackgroundVenous thromboembolism (VTE) represents a considerable burden on cancer patients' survival and quality of life, but this burden varies based on the patient's baseline characteristics and cancer-related factors. Although solid evidence on the predictors and effect of VTE in cancer patients exists.AimTo evaluate VTE rate, morbidity, and mortality to develop parameters that could predict VTEs and their associated mortality in patients with multiple primary malignancies (MPMs).Method and resultsThis was a retrospective cohort study that took place at King Abdulaziz Medical City, Riyadh,

From the Clinic to the Bench and Back Again in One Dog Year: How a Cross-Species Pipeline to Identify New Treatments for Sarcoma Illuminates the Path Forward in Precision Medicine.

Cancer drug discovery is an inefficient process, with more than 90% of newly-discovered therapies failing to gain regulatory approval. Patient-derived models of cancer offer a promising new approach to identify new treatments; however, for rare cancers, such as sarcomas, access to patient samples is limited, which precludes development of patient-derived models. To address the limited access to patient samples, we have turned to pet dogs with naturally-occurring sarcomas. Although sarcomas make up <1% of all human cancers, sarcomas represent 15% of cancers in dogs. Because dogs have similar im

Conditional deletion of E11/podoplanin in bone protects against load-induced osteoarthritis.

BACKGROUND: Subchondral bone (SCB) thickening is one of the earliest detectable changes in osteoarthritic joints and is considered a potential trigger for subsequent articular cartilage degeneration. In this manuscript, we examine whether disruption to the SCB osteocyte network contributes to the initiation and pathogenesis of osteoarthritis. METHODS: We examined expression patterns of the glycoprotein E11/podoplanin by immunohistochemical labelling in murine, human and canine osteoarthritis models. We also examined the effects of twice-weekly administration of Bortezomib, a proteasome inhibi

Assessing Heterogeneity of Osteolytic Lesions in Multiple Myeloma by ¹H HR-MAS NMR Metabolomics.

Multiple myeloma (MM) is a malignancy of plasma cells characterized by multifocal osteolytic bone lesions. Macroscopic and genetic heterogeneity has been documented within MM lesions. Understanding the bases of such heterogeneity may unveil relevant features of MM pathobiology. To this aim, we deployed unbiased ¹H high-resolution magic-angle spinning (HR-MAS) nuclear magnetic resonance (NMR) metabolomics to analyze multiple biopsy specimens of osteolytic lesions from one case of pathological fracture caused by MM. Multivariate analyses on normalized metabolite peak integrals allowed clusteriza

Neurotransmitters in cancer: how receptor signaling and posttranslational modifications modulate tumor progression and offer new therapeutic targets.

Recent studies highlight the multifaceted roles of neurotransmitters in tumor immunomodulation, offering novel avenues for increasing therapeutic efficacy. These signaling molecules are classified into cholinergic agents, monoamines, amino acids, and peptides and regulate tumorigenesis, metastasis, and immune evasion via autocrine/paracrine pathways and receptor-mediated interactions. Notably, neurotransmitters influence tumor cell proliferation, apoptosis, and immune cell activity by modulating intracellular signaling cascades through posttranslational modifications (serotonylation and dopami
