Background: Cancer along with cardiovascular diseases are globally defined as leading causes of death. Importantly, some risk factors are common to these diseases. The process of angiogenesis and platelets aggregation are observed in cancer development and progression. In recent years, studies have been conducted on nanodrugs in these diseases that have provided important information on the biological and physicochemical properties of nanoparticles. Their attractive features are that they are made of biocompatible, well-characterized and easily functionalized materials. Unlike conventional drug delivery, sustained and controlled drug release can be obtained by using nanomaterials. Methods: In this article, we review the latest research to provide comprehensive information on nanoparticle-based drugs for the treatment of cancer, cardiovascular disease associated with abnormal haemostasis, and the inhibition of tumorassociated angiogenesis. Results: The results of the analysis of data based on nanoparticles with drugs confirm their improved pharmaceutical and biological properties, which gives promising antiplatelet, anticoagulant and antiangiogenic effects. Moreover, the review included in vitro, in vivo research and presented nanodrugs with chemotherapeutics approved by Food and Drug Administration. Conclusion: By the optimization of nanoparticles size and surface properties, nanotechnology are able to deliver drugs with enhanced bioavailability in treatment of cardiovascular disease, cancer and inhibition of cancer-related angiogenesis. Thus, nanotechnology can improve the therapeutic efficacy of the drug, but there is a need for a better understanding of the nanodrugs interaction in the human body, because this is a key factor in the success of potential nanotherapeutics.

Alternative drug delivery approaches to treat cardiovascular diseases are currently under intense investigation. In this domain, the possibility to target the heart and tailor the amount of drug dose by using a combination of magnetic nanoparticles (NPs) and electromagnetic devices is a fascinating approach. Here, an electromagnetic device based on Helmholtz coils was generated for the application of low-frequency magnetic stimulations to manage drug release from biocompatible superparamagnetic Fe-hydroxyapatite NPs (FeHAs). Integrated with a fluidic circuit mimicking the flow of the cardiovascular environment, the device was efficient to trigger the release of a model drug (ibuprofen) from FeHAs as a function of the applied frequencies. Furthermore, the biological effects on the cardiac system of the identified electromagnetic exposure were assessed in vitro and in vivo by acute stimulation of isolated adult cardiomyocytes and in an animal model. The cardio-compatibility of FeHAs was also assessed in vitro and in an animal model. No alterations of cardiac electrophysiological properties were observed in both cases, providing the evidence that the combination of low-frequency magnetic stimulations and FeHAs might represent a promising strategy for controlled drug delivery to the failing heart.

The paper is a review devoted to insulin-like growth factor 1 and its role in the development, progression, and prognosis of cardiovascular diseases. IGF-I is one of the important regulatory proteins involved in both adaptation and maladjustment. The purpose of the review is to critically analyze the results of association between IGF-1 and cardiovascular disease. In general, we analyzed 100 literature sources; however, 49 of them were excluded, since the processes under consideration were not described there in detail or included an assessment of correlation between IGF-1 and metabolic parameters. IGF-I regulatory function is to control the synthesis and degradation of proteins, provide a mitogenic effect, and influence apoptosis. IGF-1 plays a leading role in the protection of cardiomyocytes from apoptosis both in vitro and in vivo. IGF-1 is involved in angiogenesis and development of atherosclerosis; it induces the growth of endothelial cells activating vascular endothelial growth factor. An increase in IGF-1 level accompanies arterial hypertension; a decrease in IGF-1 concentration is associated with an increased risk of coronary heart disease, stroke, and heart failure.IGF-1 concentration in ACS is associated with the syndrome outcome; a decrease in IGF-1 levels in patients with myocardial infarction (less than 150 nm/ml) is an unfavorable prognostic factor for six-month mortality after acute coronary pathology. Low IGF-1 level is an independent predictor of vascular accidents in hypertensive patients. Decreased IGF-1 level in patients with cardiovascular disease is associated with a higher risk of atrial fibrillation. The results obtained indicate the advisability of using the IGF-1 concentration as a prognostic marker of cardiovascular diseases. Key words: insulin-like growth factor, arterial hypertension, acute coronary syndrome, apoptosis, cardiovascular diseases, remodeling. Статья представляет собой обзор исследований, посвященных изучению роли инсулиноподобного фактора роста-1 в развитии, прогрессировании, прогнозе кардиоваскулярных заболеваний. IGF-I является одним из важных регуляторных белков, участвующих в процессах как адаптации, так и дезадаптации. Цель обзора – провести критический анализ результатов исследований взаимосвязи IGF-1 и сердечно-сосудистых заболеваний. Проанализировано 100 источников литературы, из них 49 источников исключены, так как интересующие процессы не были подробно описаны или включали оценку взаимосвязей IGF-1 с метаболическими параметрами. Регуляторная функция IGF-I заключается в регуляции синтеза и распада белков, оказании митогенного эффекта, влиянии на апоптоз. IGF-I играет ведущую роль в защите кардиомиоцитов от апоптоза как in vitro, так и in vivo. IGF-I принимает участие в развитии атеросклероза и в ангиогенезе, он индуцирует рост эндотелиальных клеток, участвуя в активации фактора роста эндотелия сосудов. Повышение уровня IGF-I сопровождает артериальную гипертензию, уменьшение концентрации IGF-I ассоциируется с повышенным риском развития ишемической болезни сердца, инсульта и сердечной недостаточности. Концентрация IGF-I при ОКС связана с исходом данного синдрома, снижение уровней IGF-I у пациентов с инфарктом миокарда (менее 150 нм/мл) является неблагоприятным прогностическим фактором полугодовой летальности после острой коронарной патологии. Низкий уровень IGF-1 – это независимый предиктор развития сосудистых катастроф у пациентов с артериальной гипертензией. Снижение уровня IGF-1 у пациентов с кардиоваскулярной патологией связано с более высоким риском развития фибрилляции предсердий. Полученные результаты свидетельствуют о целесообразности использования концентрации IGF-1 как прогностического маркера кардиоваскулярных заболеваний. Ключевые слова: инсулиноподобный фактор роста, артериальная гипертензия, острый коронарный синдром, апоптоз, сердечно-сосудистые заболевания, ремоделирование.

Technetium-99m has a rich coordination chemistry that offers many possibilities in terms of oxidation states and donor atom sets. Modifications in the structure of the technetium complexes could be very useful for fine tuning the physicochemical and biological properties of potential 99mTc radiopharmaceuticals. However, systematic study of the influence of the labelling strategy on the “in vitro” and “in vivo” behaviour is necessary for a rational design of radiopharmaceuticals. Herein we present a review of the influence of the Tc complexes’ molecular structure on the biodistribution and the interaction with the biological target of potential nitroimidazolic hypoxia imaging radiopharmaceuticals presented in the literature from 2010 to the present. Comparison with the gold standard [18F]Fluoromisonidazole (FMISO) is also presented.

SARS-CoV-2 is currently considered to have emerged from a bat coronavirus reservoir. However, the real natural cycle of this virus remains to be elucidated. Moreover, the COVID-19 pandemic has led to novel opportunities for SARS-CoV-2 transmission between humans and susceptible animal species. In silico and in vitro evaluation of the interactions between the SARS-CoV-2 spike protein and eucaryotic angiotensin-converting enzyme 2 (ACE2) receptor have tentatively predicted susceptibility to SARS-CoV-2 infection of several animal species. Although useful, these data do not always correlate with in vivo data obtained in experimental models or during natural infections. Other host biological properties may intervene such as the body temperature, level of receptor expression, co-receptor, restriction factors, and genetic background. The spread of SARS-CoV-2 also depends on the extent and duration of viral shedding in the infected host as well as population density and behaviour (group living and grooming). Overall, current data indicate that the most at-risk interactions between humans and animals for COVID-19 infection are those involving certain mustelids (such as minks and ferrets), rodents (such as hamsters), lagomorphs (especially rabbits), and felines (including cats). Therefore, special attention should be paid to the risk of SARS-CoV-2 infection associated with pets.

Polymethoxyflavanoids (PMFs) have exhibited a vast array of therapeutic biological properties. 5-O-Demethylnobiletin (5-DN) is one such PMF having anti-inflammatory activity, yet its role in hepatoprotection has not been studied before. Results from in vitro study revealed that 5-DN did not exert a high level of cytotoxicity on HepG2 cells at 40 μM, and it was able to rescue HepG2 cell death induced by carbon tetrachloride (CCl4). Subsequently, we investigated acute liver injury on BALB/c mice induced by CCl4 through the intraperitoneal injection of 1 mL/kg CCl4 and co-administration of 5-DN at (1 and 2 mg/kg) by oral gavage for 15 days. The results illustrated that treatment with 5-DN attenuated CCl4-induced elevated serum aminotransferase (AST)/alanine aminotransferase (ALT) ratio and significantly ameliorated severe hepatic damage such as inflammation and fibrosis evidenced through lesser aberrations in the liver histology of 5-DN dose groups. Additionally, 5-DN efficiently counteracted and equilibrated the production of ROS accelerated by CCl4 and dramatically downregulated the expression of CYP2E1 vitally involved in converting CCl4 to toxic free radicals and also enhanced the antioxidant enzymes. 5-DN treatment also inhibited cell proliferation and inflammatory pathway abnormally regulated by CCl4 treatment. Furthermore, the apoptotic response induced by CCl4 treatment was remarkably reduced by enhanced Bcl-2 expression and noticeable reduction in Bax, Bid, cleaved caspase 3, caspase 9, and apaf-1 expression. 5-DN treatment also induced the conversion of LC3 and promoted the autophagic flux. Conclusively, 5-DN exhibited hepatoprotective effects in vitro and in vivo and prevented liver fibrosis induced by CCl4.
