Aspects of excessive antibiotic consumption and environmental influences correlated with the occurrence of resistance to antimicrobial agents
International audience; This article explores the correlation between specific aspects of antibiotic usage, their resistance development, and environmental factors. The indiscriminate use of antibiotics led to environment contamination, selection and spreading of antibiotic-resistant organisms, and alteration of the microbial ecosystems balance. Sociobehavioural environmental factors and changes in the natural environment are major contributors to resistance development. Resistant bacteria strains' isolation in food, water, soil etc. demonstrates the environmental influence on the strains through antibiotics accumulation in the environment. It is difficult to assess the impact of antibiotic…
Immuno-toxicological Evaluation of the Adjuvant Formulations for Experimental Anti-meningococcal Vaccines without Aluminium Hydroxide
International audience; The proteoliposomes and cochleates are used as adjuvants for vaccines since they are potent immune stimulators. However, the hyper stimulation of the immune system provoked by adjuvants can cause immunetoxicological side effects. The present study was carried out to evaluate the toxic and immuno-toxicological effects of new adjuvants for anti-meningococci vaccines based on neo-proteoliposomes (nPL) and neocochleates (nCh), in Balb/c mice that were administered doses of 15 µg each, over periods of 14 days through intramuscular route and three inoculations with the same doses through intranasal route, every 7 days. The Scanning and Transmission Electron Microscopy show…
The Effects of Oregano Oil on Fungal Infections Associated with Metabolic Syndrome
International audience; This study aims to compare the evolution of mycosis associated with metabolic syndrome under allopathic treatment compared to phytotherapy using oregano essential oil. The study was conducted over a period of 6 months, on a total of 72 patients diagnosed with fungal infections associated with metabolic syndrome. The patients were divided into 3 groups, depending on the administered treatment: group 1: 24 patients who received allopathic treatment; group 2: 24 patients who received oregano oil treatment; group 3: control, which did not undergo any antifungal treatment. All three groups were subjected to specific diet therapy for mycosis. The patients were initially ev…
Assessment of Physical and Chemical Stability of Different Magnesium Compounds in Tablets
Modern lifestyle, excessive chemicalization of agricultural products, excessive processing and refining of food, cause a decrease in daily intake of magnesium, cation with an extremely important role in prevention and treatment of many diseases. As a result, there arises the need for extra magnesium intake in the form of dietary supplements. In this study were evaluated the physical and chemical stability of magnesium-containing tablets, depending on the active compound and the excipients used. Magnesium tablets in the form of orotate, lactate, citrate, oxide and hydroxide were taken into study and physical and chemical stability were observed over the validity period, at 6 and at 12 month…
The antimicrobial activity of honey and propolis extracts from the central region of Romania
Abstract Honey and propolis from Apis mellifera (bees) are products that have been used due to their multiple biological properties. The antimicrobial activity of 10 honey samples of known origin and 4 propolis extracts gathered from the same beekeepers located in Transylvania, Romania, were used against certain microorganisms: Escherichia coli, Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa and Candida albicans. The study also investigated the positive interaction of propolis aqueous extracts when used with poly-floral honey against the same microorganisms. The most sensitive to the activity of honey samples was the S. aureus strain (the largest inhibition area 18 mm) for p…
Stimuli-Responsive Polymeric Nanocarriers for Drug Delivery, Imaging, and Theragnosis.
In the past few decades, polymeric nanocarriers have been recognized as promising tools and have gained attention from researchers for their potential to efficiently deliver bioactive compounds, including drugs, proteins, genes, nucleic acids, etc., in pharmaceutical and biomedical applications. Remarkably, these polymeric nanocarriers could be further modified as stimuli-responsive systems based on the mechanism of triggered release, i.e., response to a specific stimulus, either endogenous (pH, enzymes, temperature, redox values, hypoxia, glucose levels) or exogenous (light, magnetism, ultrasound, electrical pulses) for the effective biodistribution and controlled release of drugs or genes…
An Exploratory Research of 18 Years on the Economic Burden of Diabetes for the Romanian National Health Insurance System
The prevalence of diabetes mellitus (DM) rises constantly each year worldwide. Because of that, the funds allocated for the DM treatment have increased over time. Regarding the number of DM cases, Romania is among the top ten countries in Europe. Based on the National Diabetes Programme (NDP), antidiabetic drugs and other expenditures (Self-monitoring blood glucose (SMBG) test, HbA1c, insulin pumps/insulin pumps supplies) are free of charge. This programme has undergone many changes in drugs supply, in the last two decades: re-organizing the NDP, authorization of new molecules with high prices (e.g., SGLT-2 inhibitors, etc.) or new devices (e.g., insulin pumps, etc.) The main purpose of thi…
Incidence and Clinical Implications of Autoimmune Thyroiditis in the Development of Acne in Young Patients
Autoimmune thyroiditis (AIT) is on the rise among the population, and is frequently associated with patients with acne vulgaris, especially females aged between 18–55 years old. The connection between the two is not fully elucidated. In this study, 236 patients diagnosed with acne in the dermatological office of the private Pelican Hospital and in few private dermatological offices from Oradea, Romania, during January 2018–December 2020, aged between 12 and 55 years old, were endocrinologically investigated to determine AIT and its influence on the severity of the acne. The values for the thyroid antibodies and thyroid-stimulating hormone (TSH) were determined for all of the subjects. The f…
Barrier properties of anti-gas military garments, considering exposure to gas organic compounds
The problems of determining the protective properties of barrier materials used for the production of body surface protection products of an isolative type are very actual. These garments are expected to have long-term resistance against permeation of toxic substances. The paper deals with the study of the effect of organic solvent vapours on the changes in protective properties of selected anti-gas protective garments commonly used by the North Atlantic Treaty Organization armed forces. Permeation measurements of selected gases with integral permeameter were performed to verify their barrier properties, surface changes after exposure to selected solvents by using a 3D optical profilometer,…
Protecting emergency workers and armed forces from volatile toxic compounds: Applicability of reversible conductive polymer-based sensors in barrier materials
International audience; Barrier materials have wide applicability in both professional (military, medical, industrial) and non-professional(leisure and sports) fields. This paper focuses on the preparation of real conductive polymer (CP) sensors, for thestudy of the permeation of volatile toxic compounds through barrier materials.
