  • Saliba, Elisabeth (Notre Dame University-Louaize, 2020-12)
    Prostate cancer (PCa) is the most frequent cancer malignancy among men and the third leading cause of cancer death in the developed world. To date, the exact molecular mechanism underlying the role of caffeine one of the major coffee constituents on PCa prognosis is not yet unraveled. Caffeine has many antioxidant, anti-inflammatory and anti carcinogenic properties through the modulation of certain inflammatory markers such as IL-6 and TNF-α. The present study was carried out to evaluate the effect of caffeine on PCa cell lines viability, namely PC3 and PC3-PSMA and assessing as well their ...

    Candida albicans, is usually a harmless fungus in healthy individuals, but life-threatening when found in large quantities or in inappropriate parts of the body. It developed resistance against the antifungal drugs fluconazole and amphotericin B, used in an abusive way, by adopting different mechanisms. Medicinal plants, which offer a wide variety of secondary metabolites, especially saponins, have been reported for their large biological activities. These phytochemicals are composed of a hydrophobic part (aglycone) and a hydrophilic one (glycone), which, based on their aglycone part, are ...

    Eggs are one of nature’s most nutritious and economical foods. Besides their nutritional value, antioxidant, anti‐cancerous, antihypertensive activity, and immunomodulatory effects, chemical and microbial contamination of eggs pose a risk on human health. Chemical contamination is due to the abuse of antibiotics in poultry. Microbial contamination can be through horizontal or vertical transmission. Microbial contamination accompanies a high risk of spread of antibiotic resistance. Microbial contamination can be controlled by choosing the egg source wisely and by storing eggs carefully. A lot of ...

    Antibiotic resistance and prevalence of hospital (HAI) and community-acquired (CAI) infections are significantly increasing in the world, though very few studies are addressing this topic in Lebanon. Therefore, this meta-analysis aims to identify antibiotic (AB) resistance prevalence among hospital and community acquired infections. Literature databases were searched for antibiotic resistance, HAI, and CAI in Lebanon from 2010 to 2020. To be eligible for inclusion, studies had to report data in Lebanon published between 2010 and 2020, antibiotic resistance in microorganisms responsible for either ...

    Herein, we describe, a simple method for the synthesis of dendrigraft poly-L-lysine (d-PLL) coated gold nanoparticles in water (AuNPs-d-PLL) as potential vehicles of siRNA delivery to prostate cancer cells, PC3-PSMA. AuNPs-d-PLL with diameters ranging between 50 ̶ 130 nm have been synthesized in aqueous solutions using d-PLL (7 KD) as a capping ligand and L-ascorbic acid as a reducing agent. The size of the resulting AuNPs was found to depend on several parameters, such as the concentrations of gold salt, reducing agent, and d-PLL. The obtained AuNPs-d-PLL were characterized using UV-visible ...

    Abrupt work schedules, such as nightshifts, are prevalent nowadays and are known to cause circadian misalignment and sleep disruption which can have adverse health consequences. Among the well documented pathologies among night workers are cardiometabolic impairments, the effects of which appear to be more disruptive in older adults due to their poorer adaptation to night work schedules. The physiological mechanisms by which night shift work and sleep disruption contribute to increased cardiovascular disease (CVD) risk are poorly understood. Furthermore, the potential role of specific CVD ...
  • Koliana, Rita (2022)
    Green synthesis of metallic nanoparticles has accumulated an ultimate interest over the last decade due to their distinctive properties that make them applicable in various fields of science and technology. Metal nanoparticles that are synthesized by using plants have emerged as nontoxic and ecofriendly. In the current study, the optimal reaction condition for the synthesis of zero valent iron nanoparticles using Malva extract was developed. For the first time, aqueous extract of Malva parviflora was used as a sustainable source of reducing and capping agents to synthesize zero valent iron ...
  • Hajje, Thilda (Notre Dame University-Louaize, 2022)
    Vaccination is a preventive measure to reduce death and morbidity against infectious diseases, and has been applied effectively against most of the viral and bacterial infections around the world. Targeted campaigns against children diseases have been very effective in drastically reducing such diseases thanks to national immunization programs in both developed and developing countries. However, many individuals including parents of various ages are still reluctant to commit to vaccination and some recent fears have been increasing when it comes to vaccination more recently, especially due to ...
  • Al Hassanieh, Joelle (Notre Dame University-Louaize, 2022)
    Humans are exposed to a notable variety of toxicants including lead as a heavy metal resulting from occupations and through environmental accumulation as in the Lebanese coastal and freshwaters. It is well established that lead exposure in the workplace contributes to worker infertility and decreased reproductive efficiency. Several reports have reported the detrimental impact toxic effects on human male reproduction by subsiding libido, spermatogenesis, semen quality, hormonal production and regulation, and much more. The objectives of this study were to inspect the effects of ...
  • Shaabo, Layal (Notre Dame University-Louaize, 2022-05)
    Chronic sleep restriction (CSR) has been implicated in higher risk of insulin resistance (IR) and immune-metabolic dysfunction. No studies investigated the effect of CSR on macrophage differentiation in vWAT in relation to leptin synthesis and glucose homeostasis. Therefore, this study aimed at assessing blood glucose levels and vWAT expression of leptin, CD38, and CD163 following CSR. Adult male C57BL/6 mice were housed under 12:12 L/D cycle (lights on at 0700 hrs) with free access to food. Following a two-week acclimatization period, animals were divided into 2 groups: 1) control (C, N=8) ...
