Систематический обзор потенциального ускорения нееврокогнитивного старения пожилых лиц, переживших рак.

По мере роста показателей выживаемости больше внимания стало уделяться возможным когнитивным сиквелам у пожилых больных раком, что можно объяснить ускоренным старением мозга. В этом обзоре мы представляем полный обзор исследований, посвященных нейроимации, нейрокогнитивным и нейродегенеративным расстройствам у пожилых выживших жертв рака (см.>65 лет), на основе three базы данных (Pubmed, Web of Science and Medline). Ninety-six В него были включены исследования. Были обнаружены данные о функциональных и структурных изменениях в мозге (фронтальные области, базальная ганглиа, серые и белые вещест

Business Risk Mitigation in the Development Process of New Monoclonal Antibody Drug Conjugates for Cancer Treatment.

Recent developments aim to extend the cytotoxic effect and therapeutic window of mAbs by constructing antibody-drug conjugates (ADCs), in which the targeting moiety is the mAb that is linked to a highly toxic drug. According to a report from mid of last year, the global ADCs market accounted for USD 1387 million in 2016 and was worth USD 7.82 billion in 2022. It is estimated to increase in value to USD 13.15 billion by 2030. One of the critical points is the linkage of any substituent to the functional group of the mAb. Increasing the efficacy against cancer cells' highly cytotoxic molecules (

Отличительные стратегии распознавания tRNA, используемые гомологической семьей редактирующих доменов, предотвращают неправильный перевод.

Ошибки в синтезе белка из-за пропускания аминокислот с tRNA ставят под угрозу жизнеспособность клеток. Было описано несколько контрольно-пропускных пунктов для предотвращения образования Ala- и Cys-tRNA(Pro), в том числе специально для Ala редактируемый домен (INS) большинства бактериальных проли-тринских синтезаторов (PRS) и автономный однодомный INS homolog, YbaK, который очищает Cys-tRNA(Pro) в транс. Во многих видах, где у ПРОРС нет домена INS, за редактирование Ala-tRNA(ProXp-ala) отвечает другой однодомный белок, похожий на INS. Хотя аминокислотная специфичность этих доменов редактирован

Структурный анализ процесса сбора света с помощью антенн, содержащих родопсины в морской архееи Асгарда.

Акватические бактериальные редопсиновые протонные насосы собирают световую энергию для фотогетертрофного роста и, как известно, содержат гидроксилированные каротеи, расширяющие волны используемого света, но они не характеризуются морской археей. Здесь, комбинируя морскую хромофорную экстракт с очищенными архейскими родопсинами, выявленными в морских метагеномах, мы показываем передачу легкой энергии из различных гидроксилоидных каротеоидных в геймдаллархаэ (HeimdallRs) из некультурных морских планктонных членов «Candidatus Cariarachaeceae» (Candidatus Asgardarchaeota). Эти светообрабатывающие

Glycoprotein Non-Metastatic Protein B: An Emerging Biomarker for Lysosomal Dysfunction in Macrophages.

Several diseases are caused by inherited defects in lysosomes, the so-called lysosomal storage disorders (LSDs). In some of these LSDs, tissue macrophages transform into prominent storage cells, as is the case in Gaucher disease. Here, macrophages become the characteristic Gaucher cells filled with lysosomes laden with glucosylceramide, because of their impaired enzymatic degradation. Biomarkers of Gaucher cells were actively searched, particularly after the development of costly therapies based on enzyme supplementation and substrate reduction. Proteins selectively expressed by storage macrop

Olive Leaf Extract (OLE) Anti-Tumor Activities Against Hematologic Tumors: Potential Therapeutic Implications for Pediatric Patients with B-Acute Lymphoblastic Leukemia.

Background/Objectives: Several studies reported that olive leaf extract (OLE) may exert potent anti-cancer activities against human solid and hematological tumors. Such effects are mostly related to the polyphenol oleuropein and its derivatives, which are highly concentrated in OLE. Here, we investigated the anti-tumor effects of OLE in vitro against human acute leukemia and lymphoma cells. Methods: Cell proliferation and apoptosis have been evaluated by flow cytometry (using CFSE and Annexin-V/7AAD, respectively) in the presence or absence of OLE at different concentrations and in combination

Иммунный транскриптомный профиль у взрослых женских свиней: доминантный статус оказывает большее влияние, чем экологическая обогащение.

ОКРУЖАЮЩАЯ СРЕДА: Оценка благосостояния сельскохозяйственных животных имеет решающее значение, однако по-прежнему отсутствуют практические физиологические средства. В этом исследовании мы проверили, обнаруживает ли периферийный транскриптом моноядерной клетки крови (PBMC) вариации в связи с благосостоянием свиней. Для этого мы сравнивали животных, состояние благосостояния которых было расценено как отличающееся из-за их жизни в более или менее обогащенной среде и из-за их различного доминирующего положения. Совы размещались в обычном помещении (C, n = 36) или обогащенного (E, n = 35) среда с д

Экспериментальный аутоиммунный энцефаломиэлит патогенез меняется в зависимости от возраста животных: воздействие выражения S100B.

Множественный склероз (MS) является основной провокационной и нетравматической причиной инвалидности среди молодых людей, при этом у пациентов среднего возраста часто появляются поздние МБ, что приводит к более слабому лечению и худшим прогнозам. Протеина S100B, связывающего кальций, выше у пациентов с сеток, и ее целевая направленность показала, что в экспериментальных моделях аутоиммунного энцефаломиелита (EAE) она может снизить остроту заболеваний. Однако в большинстве исследований по патологии MS основное внимание уделяется моделям молодого животного, что оставляет пробел в понимании возде

Mechanisms and effects of metformin on skeletal muscle disorders.

Skeletal muscle disorders are mostly genetic and include several rare diseases. With disease progression, muscle fibrosis and adiposis occur, resulting in limited mobility. The long course of these diseases combined with limited treatment options affect patients both psychologically and economically, hence the development of novel treatments for neuromuscular diseases is crucial to obtain a better quality of life. As a widely used hypoglycemic drug in clinical practice, metformin not only has anti-inflammatory, autophagy-regulating, and mitochondrial biogenesis-regulating effects, but it has a

Genetic factors and management strategies in aortic health: a literature review of inherited aortopathy.

Inherited aortopathies, including Marfan syndrome, Ehlers-Danlos syndrome, and Loeys-Dietz syndrome, are genetic disorders characterized by structural abnormalities of the aorta that predispose individuals to life-threatening complications like aneurysms and dissections. These conditions result from mutations in genes essential for maintaining aortic wall integrity, such as FBN1, TGFBR1, and COL3A1, affecting extracellular matrix components and the transforming growth factor-beta (TGF-β) pathway. Marfan syndrome has a prevalence of approximately 1 in 5000, while Loeys-Dietz syndrome and vascul

The Black Hole: CAR T Cell Therapy in AML.

Despite exhaustive studies, researchers have made little progress in the field of adoptive cellular therapies for relapsed/refractory acute myeloid leukemia (AML), unlike the notable uptake for B cell malignancies. Various single antigen-targeting chimeric antigen receptor (CAR) T cell Phase I trials have been established worldwide and have recruited approximately 100 patients. The high heterogeneity at the genetic and molecular levels within and between AML patients resembles a black hole: a great gravitational field that sucks in everything. One must consider the fact that only around 30% of

Role of Dietary Antioxidants in p53-Mediated Cancer Chemoprevention and Tumor Suppression.

Cancer arises through a complex interplay between genetic, behavioral, metabolic, and environmental factors that combined trigger cellular changes that over time promote malignancy. In terms of cancer prevention, behavioral interventions such as diet can promote genetic programs that may facilitate tumor suppression; and one of the key tumor suppressors responsible for initiating such programs is p53. The p53 protein is activated by various cellular events such as DNA damage, hypoxia, heat shock, and overexpression of oncogenes. Due to its role in cell fate decisions after DNA damage, regulato

Cancer Vaccines for Triple-Negative Breast Cancer: A Systematic Review.

Triple-negative breast cancer (TNBC) is the subtype of breast cancer with the poorest outcomes, and is associated with a high risk of relapse and metastasis. The treatment choices for this malignancy have been confined to conventional chemotherapeutic agents, due to a lack of expression of the canonical molecular targets. Immunotherapy has been recently changing the treatment paradigm for many types of tumors, and the approach of evoking active immune responses in the milieu of breast tumors through cancer vaccines has been introduced as one of the most novel immunotherapeutic approaches. Acco

This review describes the development of cryopreservation, the birth of autologous stem cell transplantation (ASCT) and its past and present use to consolidate adult patients with acute myelogenous leukemia (AML). It summarizes the first autografts in patients in relapse, the experience of autografting in complete remission (CR), using bone marrow unpurged or purged in vitro with cyclophosphamide-derivatives, and the important shift to peripheral blood stem cells. The review also discusses the results of recent studies in favor of the use of ASCT to consolidate good- and intermediate-risk pati

Challenges in Implementing Comprehensive Precision Medicine Screening for Ovarian Cancer.

Precision medicine has revolutionised targeted cancer treatments; however, its implementation in ovarian cancer remains challenging. Diverse tumour biology and extensive heterogeneity in ovarian cancer can limit the translatability of genetic profiling and contribute to a lack of biomarkers of treatment response. This review addresses the barriers in precision medicine for ovarian cancer, including obtaining adequate and representative tissue samples for analysis, developing functional and standardised screening methods, and navigating data infrastructure and management. Ethical concerns relat

Emerging Immunotherapy for Acute Myeloid Leukemia.

Several immune checkpoint molecules and immune targets in leukemic cells have been investigated. Recent studies have suggested the potential clinical benefits of immuno-oncology (IO) therapy against acute myeloid leukemia (AML), especially targeting CD33, CD123, and CLL-1, as well as immune checkpoint inhibitors (e.g., anti-PD (programmed cell death)-1 and anti-CTLA4 (cytotoxic T-lymphocyte-associated protein 4) antibodies) with or without conventional chemotherapy. Early-phase clinical trials of chimeric antigen receptor (CAR)-T or natural killer (NK) cells for relapsed/refractory AML showed

Early-Onset Osteoporosis: Rare Monogenic Forms Elucidate the Complexity of Disease Pathogenesis Beyond Type I Collagen.

Early-onset osteoporosis (EOOP), characterized by low bone mineral density (BMD) and fractures, affects children, premenopausal women and men aged <50 years. EOOP may be secondary to a chronic illness, long-term medication, nutritional deficiencies, etc. If no such cause is identified, EOOP is regarded primary and may then be related to rare variants in genes playing a pivotal role in bone homeostasis. If the cause remains unknown, EOOP is considered idiopathic. The scope of this review is to guide through clinical and genetic diagnostics of EOOP, summarize the present knowledge on rare monoge
