Phytocompounds and medicinal herbs were used in traditional ancient medicine and are nowadays increasingly screened in both experimental and clinical settings due to their beneficial effects in several major pathologies. Similar to the drug industry, phytotherapy is interested in using nanobased delivery systems to view the identification and characterization of the cellular and molecular therapeutic targets of plant components. Eugenol, the major phenolic constituent of clove essential oil, is a particularly versatile phytochemical with a vast range of therapeutic properties, among which the anti‐inflammatory, antioxidant, and anticarcinogenic effects have been systematically addressed. In the past decade, with the emerging understanding of the role of mitochondria as critical organelles in the pathophysiology of noncommunicable diseases, research regarding the role of phytochemicals as modulators of bioenergetics and metabolism is on a rise. Here, we present a brief overview of the major pharmacological properties of eugenol, with special emphasis on its applications in dental medicine, and provide preliminary data regarding its effects, alone, and included in polyurethane nanostructures, on mitochondrial bioenergetics, and glycolysis in human HaCaT keratinocytes.

Colorectal cancer (CRC) represents one of the most serious health issues and the third most commonly diagnosed cancer worldwide. However, the treatment options for CRC are associated with adverse reactions, and in some cases, resistance can develop. Flavonoids have emerged as promising alternatives for CRC prevention and therapy due to their multitude of biological properties and ability to target distinct processes involved in CRC pathogenesis. Their innate disadvantageous properties (e.g., low solubility and stability, reduced bioavailability, and lack of tumor specificity) have delayed the potential inclusion of flavonoids in CRC treatment regimens but have hastened the design of nanopharmaceuticals comprising a flavonoid agent entrapped in a nanosized delivery platform that not only counteract these inconveniences but also provide an augmented therapeutic effect and an elevated safety profile by conferring a targeted action. Starting with a brief presentation of the pathological features of CRC and an overview of flavonoid classes, the present study comprehensively reviews the anti-CRC activity of different flavonoids from a mechanistic perspective while also portraying the latest discoveries made in the area of flavonoid-containing nanocarriers that have proved efficient in CRC management. This review concludes by showcasing future perspectives for the advancement of flavonoids and flavonoid-based nanopharmaceuticals in CRC research.

(1) Background: Toxoplasma gondii infects approximately one third of the world’s human population. The seroepidemiology of T. gondii in cardiovascular patients is poorly discussed in the existing literature. We aimed to evaluate, for the first time, the seroprevalence of T. gondii in cardiovascular patients from Western Romania. (2) Methods: Serologic testing to demonstrate the presence of T. gondii antibodies was conducted in 256 patients with cardiovascular diseases and 261 matched blood donors. (3) Results: The overall seroprevalence of T. gondii antibodies was 64.06% in patients with cardiovascular diseases and 52.88% in blood donors and tended to increase with age in both groups. The seroprevalence of T. gondii antibodies was significantly higher in cardiovascular male patients (69.94%) compared to male blood donors (55.69%) (p = 0.006). When compared to the control group, a significantly higher prevalence of T. gondii antibodies was found among patients with hypertension (82.35%; p = 0.01) and unstable angina (67.56%; p = 0.02). (4) Conclusions: This study brings new epidemiological information on the prevalence of T. gondii in Romanian cardiovascular patients. T. gondii seroprevalence was significantly higher in patients with hypertension and unstable angina, suggesting that individuals with these diagnoses may be more frequently infected with T. gondii. This study may be a valuable starting point for further research to better evaluate the impact of T. gondii exposure on patients with cardiovascular diseases.

Cystic echinococcosis is a worldwide-distributed zoonotic parasitic disease. This cross-sectional study aimed to assess the seroprevalence and risk factors potentially associated with Echinococcus granulosus in healthy blood donors from Timis County, an endemic region in Western Romania. Serum samples were collected from 1347 Romanian blood donors. Serologic tests to determine the presence of anti-Echinococcus antibodies were performed using an anti-Echinococcus-ELISA immunoassay. Anti-Echinococcus antibodies were detected in 38 blood donors, indicating an overall seroprevalence of 2.8%. The seropositivity rate was 3.7% in females and 3.1% in blood donors residing in urban areas. The highest seropositivity was found in the age group of 31–40 years (3.6%). There were no significant differences between Echinococcus seropositivity and gender, area of residence, age, contact with dogs, or raising sheep. This serologic survey evaluated for the first time the presence of Echinococcus antibodies in healthy blood donors from Western Romania and the potential risk factors associated with echinococcosis. Our results suggest that this zoonotic infection might evolve asymptomatically in apparently healthy individuals. Further studies should be conducted in the general population to estimate the true extent of human echinococcosis and its risk factors.

Black chokeberry (Aronia melanocarpa Elliot) represents a rich source of dietary polyphenols and other bioactive phytochemicals with pleiotropic beneficial cardiovascular effects. The present study was aimed at evaluating the ex vivo effects of two black chokeberry extracts (BChEs), obtained from either dry (DryAr) or frozen (FrozAr) berries, on oxidative stress and vascular function in mice aortic rings after incubation with angiotensin 2 (Ang 2), lipopolysaccharide (LPS) and glucose (GLUC) in order to mimic renin–angiotensin system activation, inflammation and hyperglycemia. The identification of phenolic compounds was performed by means of liquid chromatography with a diode array detector coupled with mass spectrometry using the electrospray ionization interface. The BChE obtained from the FrozAr was rich in cyanidin glucoside, rutin and caffeic acid, while the one obtained from the dried berries was rich in rutin, caffeic acid and chlorogenic acid. Mice aortas were dissected and acutely incubated (12 h) with Ang2 (100 nM), LPS (1 µg/mL) or GLUC (400 mg/dL) in the presence vs. absence of the two BChEs (1, 10, 50, 75, 100, 500 µg/mL). Subsequently, the tissues were used for the assessment of (i) hydrogen peroxide (H2O2) and superoxide production (using two methods, spectrophotometry and immunofluorescence), (ii) H2O2 scavenger effect and (iii) vascular reactivity (using the organ bath/myograph system). After exposure to Ang2, LPS or GLUC, both types of extracts decreased the H2O2 and superoxide levels in a concentration-dependent manner starting from either 50 µg/mL or 100 µg/mL. Also, in the highest concentrations (100 µg/mL, 150 µg/mL and 500 µg/mL), both extracts elicited a significant scavenger effect on H2O2 (similar to catalase, the classic H2O2 scavenger). Moreover, at 100 µg/mL, both extracts were able to significantly improve vascular relaxation in all stimulated aortic rings. In conclusion, in mice aortas, black chokeberry extracts in acute application elicited a concentration-dependent vasculo-protective effect through the reduction of oxidative stress and the alleviation of endothelial dysfunction in ex vivo conditions that mimic cardio-metabolic diseases.

Human toxocariasis is a neglected tropical disease with a potentially major impact on public health. Our aim was to assess the seroprevalence and risk factors associated with Toxocara seroprevalence in blood donors from Romania. Serum samples were obtained from 1347 Romanian blood donors and serologically tested for anti-Toxocara antibodies. An epidemiological questionnaire was used to determine the risk factors associated with Toxocara infection. The overall prevalence of Toxocara antibodies was 29.6%, with a significant age-associated increase (p < 0.001). A higher rate was observed in individuals from rural areas compared to urban areas (p = 0.002) and in males compared to females (p = 0.001). In univariate statistical analysis, seropositivity was significantly associated with household ownership (p < 0.001), contact with soil (p < 0.001), owning dogs (p < 0.001), cats (p = 0.003), and consumption of undercooked poultry (p = 0.002). In a stepwise multivariate logistic regression model, only a lower level of education, age, male gender, consumption of undercooked or raw poultry, and contact with soil were associated with higher Toxocara seroprevalence. Our findings suggest a significant prevalence of Toxocara infection in this region. The identified risk factors highlight the necessity of health education programs that focus on public awareness and promote preventive behaviors, especially among at-risk populations.
