Objective To construct an inflammation-responsive high-density lipoprotein (HDL)-mimetic nanoparticle with anti-atherosclerotic activity using a bioinspired strategy based on a oxidation-responsive material. Methods 4-(hydroxymethyl) phenylboronic acid pinacol ester (PBAP) was chemically conjugated to β-cyclodextrin (β-CD) to synthesize a reactive oxygen species (ROS)-sensitive material.Nanoprecipitation and coextrusion methods were used to prepare HDL-mimetic nanoparticles (mHDL NP).Spectroscopy was employed to verify the structure of the synthesized material, and microscopy was utilized to observe the morphology of the nanoparticles. We observed phagocytosis of the nanoparticles by murine RAW264. 7 macrophages using flow cytometry and confocal microscopy, and examined the release of the inflammatory factors tumor necrosis factor-α (TNF-α) and monocyte chemoattractant protein-1 (MCP-1) in the supernatant by the macrophages cultured in the presence of the nanoparticles using ELISA. We also used a fluorescent ROS probe DCFH-DA to detect the changes of ROS generated in RAW264. 7 macrophages in response to the nanoparticles. Different methods were used to assess the effects of the nanoparticles on cholesterol efflux and foam cell formation in RAW264. 7 cells. Results Spectroscopy analysis showed that about 5 PBAP units were conjugated to each β-CD molecule. The prepared nanoparticles had a well-defined spherical shape with a narrow size distribution and a mean diameter of about 200 nm. In vitro experiments showed that RAW264. 7 cells phagocytosed the nanoparticles in a time- and dose-dependent manner. mHDL NP significantly inhibited the secretion of the inflammatory factors and ROS production by RAW264. 7 cells in response to inflammatory stimulation (P < 0. 05), which demonstrated potent anti-inflammatory and antioxidant activities of the nanoparticles. mHDL NP time- and concentration-dependently promoted cholesterol efflux(P < 0. 05) and significantly inhibited foam cell formation in RAW264. 7 macrophages. Conclusions We successfully synthesize HDL-mimetic nanoparticles with antioxidant and reverse cholesterol transport capacities. Our preliminary in vitro cellular evaluations demonstrate obvious anti-atherosclerotic activity of the synthesized nanoparticles.

aromatic amine, reduction, condensation, Schiff base, color product, aldehyde - Abstract
Molecules that do not ordinarily absorb radiation in the visible region of the spectrum can be made to do so by introducing chromogens that facilitate electronic transitions. The most commonly derivatized functional groups are aromatic nitro- (preliminary reduction required) and aromatic amino- groups.An amino compound that lacks chromophore can be assayed spectrophotometrically using a suitable carbonyl reagent. Certain amines condense with various aldehydes in strongly acidic media, giving them the ability to give color. Among many, the following aldehydes are widely used: 4-dimethylaminobenzaldehyde, vanillin, p-dimethylaminocinnamaldehyde, salicylaldehyde, etc. The reaction with aromatic amines produces Schiff bases.In this review, we have summarized and discussed the important analytical chromogenic reagents regularly used in drug analysis by visible spectrophotometric methods.

drug delivery systems, nanoparticles, blood-brain barrier, neurodegenerative diseases, liposomes, polymeric nanoparticles - Abstract
Parkinson's disease is a progressive neurodegenerative disease affecting more than 10 million patients worldwide. The leading cause of this pathological condition is an imbalance between dopaminergic and cholinergic systems due to dopaminergic neurons' degeneration in the nigrostriatal pathways. The primary goal of Parkinson's therapy is to correct the levels of the mentioned neurotransmitters, and the administration of Levodopa has been accepted as a "gold standard" treatment. The amino acid precursor can successfully control the symptoms by compensating for the reduced concentration of endogenous dopamine and activating postsynaptic D-receptors in the striatum.The intensive enzymatic degradation of levodopa in the gastrointestinal tract is the main reason for its low concentration in the midbrain (~1%) and the increased frequency of adverse drug reactions. Despite numerous attempts to improve clinical efficacy, increasing bioavailability and reducing side effects remain difficult. This makes it necessary to use innovative drug delivery systems capable of overcoming the problems mentioned above.This literature review presents new technological approaches for improved delivery of levodopa to the central nervous system. Nanoparticles, liposomes, cyclodextrin complexes, carbon nanotubes, and others represent promising platforms for the delivery and controlled release of the dopamine precursor. With the ability to ensure optimal bioavailability, constant plasma concentration, minimal peripheral degradation, and reduced adverse drug reactions, they successfully overcome the shortcomings of conventional levodopa-containing dosage forms.

osteoporosis, prevention, treatment, patients, awareness, adherence - Abstract
Introduction Osteoporosis is a socially significant disease with a serious burden on society that, despite advances in medicine, remains late-diagnosed and difficult to treat. Its treatment is a long and challenging process and long-term commitment to therapy is hard to achieve.Aim: The purpose of this article is to study and analyse the awareness and attitudes of osteoporosis patients and those at risk about disease diagnosis, prevention and treatment.Methods and methodology: During the months of April and May 2022, an anonymous online survey was conducted among patients with osteoporosis and people with risk factors. The questionnaire for patients and persons at risk included questions about the patient’s demographic characteristics and the attitudes of the patient and a questionnaire for determining the level of adherence to therapy.Results: Patients are well aware of the risk factors for the disease and try to lead a healthy lifestyle. Adherence to therapy was found to be suboptimal in individuals diagnosed with osteoporosis and undertaking treatment. The following are the primary reasons: prominent ADRs; inconvenience when taking medication; forgetting a dose; discontinuing medications; fear of ADRs; lack of motivation. Financial problems are also highlighted, both throughout the treatment process and for prevention and diagnostics, mainly due to the lack of free tests.Conclusion: Supporting early disease detection, patient education, and compliance and adherence to therapy are critical to treatment effectiveness. It is necessary to build a system to improve the health culture of the population through the implementation of complex health prevention programs as well as screening for early diagnosis of patients with osteoporosis and people at risk.

gentamicin, drug stability, UV-VIS spectroscopy - Abstract
Gentamicin is one of the most commonly prescribed antibiotics in the aminoglycoside class of drugs. This is largely due to its spectrum of action, low cost, and affordability. It is both effective against gram-positive and gram-negative organisms. Gentamicin has no oral absorption, so there are no oral dosage forms. There are various commercial products on the market that contain gentamicin in the form of solutions for intramuscular and intravenous administration, eye dosage forms, as well as those for external applications. For the purposes of the present study, by using a UV-VIS spectrophotometer, we have determined the content of gentamicin in an injectable dosage form at a concentration of 40 mg/mL in ampoules with an expiration date of 2016 or 2017.

- Abstract
Diabetes Mellitus (DM) is a major metabolic disorder causing morbidity and mortality worldwide. The prominent adverse effects of allopathic drugs are the principal reason for an escalating number of people seeking alternative and complementary-based therapies that may have less or no adverse effects. The poly-herbal formulation Vilva Kudineer Choornam (VKC) is a combination of Siddha medicinal plants for the treatment of diabetes. The present study aimed to investigate the antioxidant and antidiabetic efficacy of poly-herbal formulation by invitro assays. The Aqueous Extract of Formulation (AEF) and Ethanol Extract of Formulation (EEF) were used for the assay. In the present research work, the antioxidant potential of polyherbal formulation (VKC) was evaluated using DPPH radical scavenging and Nitric oxide radical scavenging assay. The IC50 value of AEF was 333.02 ?g/ml and EEF was 86.37 ?g/ml in DPPH radical scavenging assay whereas, in nitric oxide scavenging assay, the IC50 of AEF and EEF were found to be 8.61 ?g/ml and 447.77 ?g/ml, respectively. The VKC was also screened for in-vitro antidiabetic potential by alpha-amylase inhibition assay and it was shown to have significant percentage inhibition of alpha-amylase. The IC50 of EEF and AEF were found to be 868.84 ?g/ ml and 247.09 ?g/ml, respectively. The findings suggest that the polyherbal formulation (VKC) has significant antioxidant and antidiabetic activity. Further in vitro studies using cell lines and other enzymes may be carried out to fully establish the anti-diabetic potential of the polyherbal formulation.

- Abstract
Bacterial meningitis is considered as neurologic emergency with high morbidity and mortality rates. Mortality can reach 34%, especially in infections caused by S. pneumoniae and L. meningitides, while morbidity in bacterial meningitis patients, namely long-term neurologic sequelae, can reach 50% amongst survivors. If antibiotics are used properly, they can lower mortality rates.On the other hand, the irrational use of antibiotic therapy will raise the likelihood of resistance, which raises morbidity, mortality, and costs for health care. This study aims to determine the quality of antibiotic use in bacterial meningitis patients using the Gyssens method. It is an observational study employing the retrospective cross-sectional method conducted at Fatmawati General Hospital, Jakarta. The research subjects were 24 patients with bacterial meningitis who met the inclusion criteria. In this study, 45.8% of the subjects had been administered appropriate antibiotics and 54.2% inappropriate ones, which were spread across several categories, namely category IVc for one subjects (4.2%); category IIIA for two subjects (8.3%); category IIIB for one subject (4.2%); category IIA for ten subjects (41.7%); and category IIB for two subjects (8.3%). The use of appropriate antibiotics based on evaluation using the Gyssens algorithm did not significantly affect patient outcomes (p=0.542). The independent variables (type of antibiotic therapy, number of antibiotics, duration of antibiotic use) and confounding ones (age, gender, number of comorbidities, type of comorbidities, length of treatment) also had no significant effect on the quality of antibiotic use, with a p value more than 0.05.

Abstract The programme aimed at training the fellow in the risk assessment guidelines proposed by the EFSA in the field of contaminants, food contact materials, technological ingredients and nutritional risks. It had a modular ‘learning by doing’ approach and a balanced learning/case studies and theory. Module 1 offered an insight into chemical risk assessment and conferred transferable skills for a proper application of the framework. The hands‐on activities consisted of three case studies that went from a simple exercise on an official opinion, to working in a team with experts to produce a new opinion, to an individual work to obtain a publishable review manuscript. Module 2 was a training in experimental toxicology designed to create a toxicological basis and to enable the fellow to perform toxicological studies for risk assessment purposes. She joined the team working on cyanotoxins, gained experience with both EFSA and Organization of Economic Cooperation and Development (OECD) guidelines on genotoxicity and an insight into the developing of analytical methods suitable for risk assessment purposes. During module 3, the fellow was trained in nutritional risk assessment and involved in experimental work in chemical characterisation, biomarkers and mechanisms of action of bioactive compounds. This developed the critical perspective when assessing nutritional and health claims related the design of experiments, methods used, interpretation of results and human relevance. Module 4 provided a ‘hand‐on experience’ in scientific risk communication as the fellow was encouraged and supported in the participation at local, national and international workshops and congresses presenting the outcomes of the three modules. Thus, the fellow was successfully integrated in the day‐by‐day workflow of the department, gaining first‐hand practical experience in risk assessment in a multicultural and interdisciplinary context. This enabled a productive exchange of good practices and contributed to building a European risk assessment community.

acne, cost-effectiveness analysis, active cosmetic complex - Abstract
IntroductionAcne vulgaris is one of the most common dermatological diseases, affecting about 650 million people worldwide. The development of new anti-acne products is both time- and cost-consuming. The cost-effectiveness analysis enables an economic evaluation of the resources invested and the results obtained. AimThe aim of the study is to evaluate the cost-effectiveness of seven new active complexes of natural origin developed for use in cosmetic products for oily and acne-prone skin. Materials and methodsThe active complexes were designated as A, B, C, D, E, F, and G. Volunteers with a mild to moderate form of acne, between 18 and 60 years of age, applied various cosmetic products with the active complexes for a period of 2 to 8 weeks. Their skin condition was assessed by a dermatologist, both at the beginning and at the end of their treatment. A cost-effectiveness analysis was performed by determining the average cost per unit outcome and calculating an incremental cost-effectiveness ratio (ICER). ResultsThe cost per unit of effect (1% skin condition improvement) in euros was calculated for each of the active complexes. The calculation was based on the percentage content of the active ingredient necessary to obtain the maximum effect for the corresponding period of application. The cost-effectiveness ratio (CER) has the lowest value of 0.0028 EUR for alternative C, that dominates over the others. The rest of the active complexes are in the following order: B > F > E > G > D > A. After calculating the ICER, the highest added value was observed when comparing complex A with C (0.2405 EUR for an additional 1% improvement) and the lowest when comparing F with D (0.00031 EUR for an additional 1% improvement). ConclusionThe analysis of the results shows that in a test for in vivo efficacy in acne, the most "cost-effective" solution is active complex C (based on avocado oil). According to the cost-effectiveness analysis, it could be considered a cost-effective alternative to the other active complexes.

SEDDS, lipids, absorption, microemulsion, nanoemulsion - Abstract
The oral route of drug administration is the most effective and the most widely applicable, as it is characterized by high therapeutic efficiency, a low production cost, and very good patient acceptance. Before a drug enters the bloodstream, it must go through stages of dissolution and overcome biological membranes. However, most drugs are characterized by low solubility and/or permeability in the gastrointestinal tract environment. These disadvantages can be overcome by various technological approaches, such as micronization, the formation of salts and complexes, solid dispersions, the use of mucoadhesive polymers, as well as lipid-based drug delivery systems such as the self-emulsifying systems (SEDDS). In recent years, SEDDS have been one of the most popular approaches to increasing oral bioavailability, as they have the potential to reduce the administered dose and protect unstable drugs from the aggressive conditions in the gastrointestinal tract.Depending on their preparation and composition, SEDDS can improve the deficiencies of drugs belonging to biopharmaceutical classes II to IV. Furthermore, depending on the type of dispersion formed, they can be classified into micro-SEDDS, nano-SEDDS, o/w-SEDDS, and w/o/w-SEDDS.

depression, screening, prevention, chronic diseases, pharmacists - Abstract
Depression is one of the leading disability factors worldwide, causing a loss of workability as well as economic and financial burdens. Depression walks hand-in-hand with different chronic illnesses like cardiovascular, endocrine, neurodegenerative, rheumatological, or oncological, due to which it can be overlooked and stay undiagnosed for a long time. The pharmacist’s role in finding and preventing depression in patients that are at risk, suffering from concomitant chronic diseases, has been researched. Patients were screened with the help of a specifically made questionnaire that gathers information on patients’ socio-demographic characteristics, as well as the PHQ-9, which focuses on finding how big the risk of depression is. The questionnaires were filled out in pharmacies in Sliven and Yambol from March to April 2022 and included 74 patients with chronic diseases. Results from the screening show that every chronically ill person who answered the questionnaire is at risk for depression, with 34% having moderately severe depression, 30% being severely depressed, 27% being moderately depressed, and only 9% showing slight signs of depression. This reinforces previous medical research indicating individuals suffering chronic diseases are more prone to developing depression, which might go unnoticed due to their primary illness. Implementing screening programs in pharmacies and making them available around the country can be an effective tool for the early identification of depressive symptoms in patients with chronic diseases.

Introduction:Back in the 1980s many analyses indicated that the centralized preparation of cytotoxics gave the opportunity to shorten the time for their preparation, to decrease the staff exposure to their toxic impact, to minimize the unavoidable residues (to be destroyed) after their preparation; therefore, this strategy has been getting implemented in different European countries.Purpose:The aim of this article is to make a comparison between the requirements and activities on central preparation of drugs for systemic treatment of malignant disease in a couple of chosen European countries and Bulgaria. Methodology:The research has been carried out via online communication with hospital pharmacists directly involved in the centralized preparation of cytotoxics in their countries. The period of making the detailed interviews with the target respondents was June–August 2022.Results:In the 9 countries that participated in the research, patients with malignant diseases are treated only in hospitals where the centralized solution of cytotoxics are performed predominantly at hospital pharmacies. Rarely though, one can still encounter the practice of preparation of those drugs in the departments as this process has been practiced mainly in countries that have started with the centralized preparation in recent years (Bulgaria, Croatia, Romania, Lithuania).Typically for Ireland and Sweden, the treatment can be performed in places out of the hospital, too, (e.g., at medical institutions for outpatient services or at patient’s home). The solution of the drugs for systemic treatment of malignant diseases in Ireland can be achieved both at hospital pharmacies and by independent contractors upon the hospital’s order; whereas in Sweden, it is done in the so-called centralized hospital pharmacies where solutions for a couple of hospitals are prepared. In Ireland and the Netherlands, only pharmacy technicians dissolve cytotoxics; it refers to Lithuania, too, as all that is performed at the pharmacy. Mostly pharmacy technicians deal with this activity in Portugal and Estonia, while in the other countries involved in the research, the preparation is done by Masters of pharmacy and by technicians/assistant pharmacists; in Sweden there are Masters of Pharmacy and Bachelors of Pharmacy. Predominantly, safety cabinets or isolators are used and usually their choice depends on the hospital. Standards related to the centralized preparation of cytotoxics are usually at national level, they are of advisable nature as it is in Bulgaria, Estonia, Lithuania, and are based on QUAPOS.The Netherlands, Bulgaria, and Sweden have mandatory standards.

antibiotics, antimicrobial resistance, antibiotic consumption - Abstract
Introduction: Antibiotics are one of the key discoveries in human history. Unfortunately, the global rise in antimicrobial drug resistance has become one of the most pressing medical problems. Monitoring of antibiotic consumption is one of the most important components of all programs aimed at controlling the problem with the rising antimicrobial resistance.Aim: The aim of this article is to present a free and internationally standardized electronic-based method for calculating the consumption of antibiotics in hospitals and in society.Methodology: The system for classification of antibiotic agents ATC/DDD (Anatomical Therapeutic Chemi-cal/Defined Daily Dose), which is an international standard for calculation of antibiotic consumption in a univer-sal technical unit of measurement—defined daily dose, is used.Practical Examples and Recommendations: The problem with the increasing antibiotic resistance was first discussed internationally at The Microbial Threat conference in Copenhagen in 1998. Monitoring antibiotic consumption is one of the key components of The European Community Strategy Against Antimicrobial Re-sistance from 2001. For the convenience of the users, open-source free software programs, incorporating the ATC/DDD system, such as ABC Calc and AMC Tool have been created for easy calculation of antimicrobial consumption.Discussion: According to the latest ECDC report, total antibiotic consumption in EU countries has been decreasing since 2014, with data for 2020 showing that antimicrobial consumption has decreased further during the first year of the COVID-19 pandemic. The only exception is Bulgaria, where it has doubled.Conclusion: ECDC data show that our country lags significantly behind other EU countries and immediate strict measures and actions are needed to combat the rising tide of antimicrobial resistance. Given the availabil-ity of free open-source programs for monitoring antimicrobial consumption, it would be very helpful to use them more widely in Bulgarian hospitals, and hospital pharmacists should play a key role in this process.

- Abstract
The consumption of tropical fruits rich in chemopreventive compounds are required to prevent cells carcinogenesis and proliferation. This study was designed to assess de biocompatibility of Detarium microcarpum fruit extract on normal fibroblasts and its antiproliferative potentiality on human osteosarcoma MG-63 cells. Primary dermal fibroblasts and human osteosarcoma MG-63 cells were treated with different concentrations of hexane, chloroform, ethyl acetate and methanol extracts of D. microcarpum fruit pulp for 24h, 48h and 72h. The biocompatibility property of extracts on the normal fibroblasts and its antiproliferative activity on the human osteosarcoma cells were evaluated by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenytetrazolium bromide (MTT) assay. The biocompatibility study of D. microcarpum fruit pulp showed that the chloroform extract has exhibited the highest cytotoxic effect on normal fibroblasts followed by the ethyl acetate extract. Hexane extract wasn’t cytotoxic at concentrations of 125 and 250 µg/mL but caused more than 80 % of cell death at a concentration of 500 µg/mL. Methanol extract didn’t show a significant cytotoxic effect. Furthermore, chloroform and ethyl acetate extracts showed the best antiproliferative activity on osteosarcoma cells. A complete cell death was observed when osteosarcoma cells were treated with ethyl acetate extract at all concentrations while chloroform extract at concentrations of 250 and 500 µg/mL caused a complete cells death. Methanol extract exhibited any antiprolifarative activity. Chloroform and ethyl acetate extract of fruits pulp of D. microcapum are potent source of anticancer phytomolecules and have potential to be a promising anti-osteosarcoma extract.

- Abstract
The study evaluated the antioxidant and hypoglycaemic potentials of the ethanol flower extract of Bougainvillea spectabilis. Flower extract of Bougainvillea spectabilis were obtained by cold maceration method. The preliminary phytochemical screening and hypoglycaemic effect were carried out using standard methods. Antioxidant screening was carried out using DPPH antioxidant assay test. Five rats were used for each group; normal control, standard control, 100, 200 and 400 mg/kg b.w. doses of the crude ethanol flower extract of B. spectabilis to test the hypoglycaemic effect in alloxan-induced diabetic rats. Blood glucose levels were measured at different time intervals. The preliminary phytochemical screening revealed the presence of alkaloids, saponins, strerols, terpenoids, flavonoids, and carbohydrates. The crude ethanol fraction demonstrated least antioxidant activity while the chloroform fraction showed the highest antioxidant activity followed by the hexane fraction. The ethanol flower extract showed a significant dose dependent hypoglyceamic effect after 24 hours of administration. Of the doses tested, highest hypoglycaemic effect was observed by the ethanol flower extract of the dose 400 mg/kg at 24 hours. The findings revealed that non-polar fractions have more antioxidant activity than the polar fractions while the ethanol flower extract of Bougainvillea spectabilis possesses a delayed hypoglycaemic effect.

- Abstract
Lung cancer is the leading cause of cancer deaths worldwide, and this makes it an attractive disease to review and possibly improve therapeutic treatment options. he extreme lethality of lung cancer is ascribed to the lack of early diagnostic strategies as in almost 50 % of the cases the disease is confirmed in stage IV, leaving low chance of survival. The inaccessibility to the deeper portions of the lung for conventional therapy further adds up to the complication in the treatment process. Surgery, radiation, chemotherapy, targeted treatments, and immunotherapy separate or in combination are commonly used to treat lung cancer. However, these treatment types may cause different side effects, and chemotherapy-based regimens appear to have reached a therapeutic plateau. Hence, effective, better- tolerated treatments are needed to address and hopefully overcome this conundrum. Nanocarriers through inhalational route offer many advantages like; 1) they achieve uniform distribution of drug among the alveoli, 2) better solubilization of the drug, 3) sustained drug release which subsequently decreases dosing frequency, 4) better patient compliance, 5) lesser side effects, and 6) improved drug internalization to the cells .Therefore, targeted inhalable NP delivery to the lungs is a potential area of research in cancer nanotechnology that catches the attention of many formulation scientists, oncologists, and biomedical researchers. Based on this literature review, we will discuss the development, characterization, and benefits of inhalable nanocarriers for local treatment of lung carcinoma.

- Abstract
Context: Schistosomiasis continues to be the leading cause of morbidity and mortality among the neglected tropical diseases. Apart from the high cost of chemotherapy, concerns over drug resistance and tolerance have been raised in the past decade. Objective: The aim of the study was to evaluate the anticercarial activity of extracts and compounds from the stem bark of Holarrhena floribunda on cercaria of Schistosoma haematobium. Methods: Hydroethanolic and alkaloidal extracts from the stem bark of H. floribunda were tested on cercaria at concentrations between 500.00 and 15.625 μg/mL for 180 minutes and assessing the percentage viability at time intervals of 0, 15, 30, 60, 120 and 180 minutes. Praziquantel, used as reference drug, and the isolated compounds were tested at similar concentrations. The cercaria mortalities and IC50 of extracts and compounds were estimated after 30 minutes of incubation. Results: The 70 %v/v ethanol extract showed the highest activity (IC50=20.09±1.11 μg/mL) with praziquantel giving IC50 of 695.50±1.12. The alkaloids holonamine, holadienine and conessine, isolated from the stem bark, showed considerable cercaricidal activity with the latter recording an IC50 of 33.28±1.04. Conclusion: The study gives first-hand knowledge of the anti-cercarial activity of H. floribunda and its steroidal alkaloids. This gives credence to the traditional uses of the plant as an anti-parasitic agent.

- Abstract
Bougainvillea spectabilis Willd. is an ornamental plant cultivated in tropical, subtropical regions and other places as Egypt. The present study aimed to perform bioassay guided fractionation and isolation of some of the bioactive compounds from the Egyptian cultivate. The total ethanol extracts of the leaves (T.ET.L.), stems (T.ET.S.) and flowers (T.ET.F.) were screened for some pharmacological activities viz. in vivo anti-oxidant and anti-hepatotoxic, in addition to in vitro cytotoxic activities. The anti-oxidant effect was assessed by measuring serum glutathione level (GSH) in alloxan-induced diabetic rats. The anti-hepatotoxic activity was evaluated via measuring serum markers level viz. alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in CCl4-induced hepatotoxicity in rats. In vitro cytotoxicity of the different extracts was estimated for liver cancer cell line (HEPG2) adopting Sulforhodamine B stain assay. T.ET.L. exhibited significantly potent anti-oxidant and anti-hepatotoxic activities, while T.ET.S. showed the highest cytotoxic activity. Through biological guided fractionation, leaves and stems were subjected to successive solvent extraction, whereas the leaves ethyl acetate (Et.Ac.L.) and the stems ethanol 70% (Et.70%S.) extracts showed highly potent activities. Thus, different chromatographic techniques were performed on Et.Ac.L. and Et.70%S. extracts leading to the isolation of five bioactive metabolites. Three flavonoids were isolated from Et.Ac.L.; genistein-7-O-rutinoside (1), formononetin-7-O-rutinoside (2) and myricetin (3), while orobol-7-O-glucoside (4) and hesperidin (5) were isolated from Et.70%S. This work demonstrated the importance of the plant as a promising anti-oxidant, anti-hepatotoxic and cytotoxic product for nutraceutical use.

- Abstract
In this paper the impact of air pollution on the bronchial reactivity of mine workers in Leposaviq - Kosovo with toxic metals such as: (SiO2, Pb, Zn, Particulate matter-PM) has been studied. Since body plethysmography is a highly sensitive and precise technique in the research of phenomena affecting bronchial reactivity, we have defined lung function with Body Plethysmography. Airway resistance (Raw) was recorded and Intrathoracic Gas Volume (ITGV) was measured and Specific Airway Resistance (SRaw) and specific conductance (SGaw) were calculated. The control group consisted of 35 healthy people. In our case we used histamine as a provocative test, which did not cause significant changes in bronchomotor tone (p> 0.1). In the experimental group, 59 workers of the Leposaviq - Kosovo mine were included. The results obtained from this research show that the mean Specific Resistance (SRaw), and specific conductance (SGaw) values significantly underwent changes in the experimental group compared to the control group (p <0.01). The study also found that smoking favors the adverse effects of air pollution on workers’ health. To the workers exposed to high concentrations of air pollution found change in lung function, increased bronchial reactivity, and impaired lung function at the level of gas exchange, namely a decrease in O2 partial pressure and an increase in pacific CO2 pressure in arterial blood. We also have a reduction in carbon monoxide transfer factor (p <0.01).

- Abstract
Alpha-1 antitrypsin (AAT) is a serine protease inhibitor. A low level of serum AAT (<11 µM) is defined as AAT deficiency. The limitations of the current treatments for AAT deficiency-related lung disease are the low AAT lung penetration rate following intravenous infusion and the rapid AAT clearance from the lung following inhalation. Here, we present a PEGylated version of AAT, which shows improved resistance to proteolysis in vitro. In vivo, PEGylated AAT exhibits prolonged body residency after delivery by the intravenous and intratracheal routes. In a murine COPD model, a low intranasal dose of PEGylated AAT achieves better efficacy than a 45-fold higher intravenous dose of AAT. PEGylated AAT represents a promising alternative for AAT augmentation therapy., (BIFA - Sciences biomédicales et pharmaceutiques) -- UCL, 2022

- Abstract
Vagus nerve stimulation (VNS) is an established treatment for drug resistant epilepsy (DRE), which affects about 30% of epilepsy patients. On-demand triggering of VNS is known to improve its efficacy in DRE. Automatic on-demand VNS needs an effective and reliable seizure detection method. As seizures are commonly associated with autonomic manifestations and the vagus nerve carries parasympathetic and sensory information from and to the viscera we hypnotize that seizure biomarker can be recorded from vagus nerve electroneurogram (VENG) recording. In this thesis we established a method to reliably record VENG signals in anesthetized animals during acute pentylenetetrazol induced seizures and confirmed the neural origin of those signals. Furthermore, we confirmed the existence of seizure related signals in the VENG recording and developed a seizure detection method based on them., (BIFA - Sciences biomédicales et pharmaceutiques) -- UCL, 2022

- Abstract
Oil and its derivatives spills have been a major issue across decades due to transport, import, Export and accidents with its wider use in industry and it is difficult to be biodegraded. Many techniques were developed to clean up petroleum contaminated soil, among all of them, the biological treatments are more efficient and economic compared to chemical and physical ones. Bioremediation is applied as a treatment technology that is cost-effective, ecologically friendly and efficient for the decontamination of hydrocarbon pollution. In this study, crude oil contaminated soil samples were collected from oil extraction fields in Libya. The bacterial strains were isolated using selective media (agar containing crude oil). Isolated bacteria were identified using microbial features and selective media and then used in biodegradation experiment of 0.5% and 1% of crude oil contaminated soil. The bacterial concentration was adjusted to 1.5 x 108 scf/ml before supplementing in the soil. Three plants were chosen to perform experiment (Malva punilora, Ricinus communis and Triticum repens) on 0.5% and 1% crude oil contaminated soil. The chosen species were implanted directly in the contaminated soil together with prepared bacterial consortia. Soil sample (triplicate) was taken from each experiment at zero time, after 15 days, and 30 days of experiment, hexane was added to the soil samples and the absorbance was measured using spectrophotometer at 360 nm. As a result, two bacterial strains proved to be oil biodegrades were isolated and identified as Escherichia coli and other bacillus bacteria. The percentage of crude oil removal by bacteria was more than 60% in the soil contaminated by 0.5% of crude oil after 15 and 30 days of experiment, while it was 30% at 1% crude oil contaminated soil after 15 days and increased to be 75% after 30 days of experiment. The experiment included combination between plants and bacteria resulted in the 90% of removal by Triticum repens and bacteria

- Abstract
Cystic fibrosis, CF, is one of the most common life-shortening genetic diseases among Caucasian population. It is a recessive genetic disease that is mainly caused by different types of mutations affecting the gene encoding for the cystic fibrosis transmembrane conductance regulator, CFTR, protein. CFTR is a multifunctional protein found in multiple organs in the human body, acting mainly as a trans-epithelial channel which regulates the flow of chloride and bicarbonate ions across epithelial membranes leading to the formation of a thin slippery mucous layer. A malfunctioning CFTR protein would lead to the accumulation of a thick viscous mucous layer blocking pancreatic ducts, intestines and airways which is the primary reason of death. Treatment of cystic fibrosis was mainly addressing the symptoms to overcome the complications of the disease such as pneumonia, lung infections, pancreatitis, maldigestion and infertility. Since the early 2010’s, the development of an actual therapy has reached great milestones including small molecule modulators and genetic therapy. Small molecule therapy depends on the development of small pharmacological agents that can bind to the mutated CFTR protein restoring its function. Pharmacological agents can act through different mechanisms and be mainly classified to; correctors and potentiators. On the other hand, gene-editing techniques are evolving showing very promising results. Gene therapy entails the relocation of a proper copy of the CFTR gene in the aim of expressing a functional CFTR protein. In this review article, small molecule and genetic therapies will be discussed including their development, benefits and limitations.

The effect of Justicia gendarussa leaves extract has been investigated using oxonate-induced hyperuricemic malealbino rats. In this experiment thirty five male albino rats were divided randomly into seven groups. There were threegroup doses variations of J. gendarussa extract that were 1.3 g/kg bw, 2.6 g/kg bw and 5.2 g/kg bw; two comparisongroups that were allopurinol 0.68 g/kg bw and herbal “X” 0.85 g/kg bw; and two control groups that were inducedcontrol potassium oxonate 0.25 mg/kg bw and normal control CMC 0,5 %. Intraperitoneal administration of potassiumoxonate 0.25 mg/kg bw was given one hour before administration of test drugs in eight day and plasma uric acid wasmeasured in rats after two hours. Plasma uric acid was measured by spectrophotometric on 520 nm with enzymaticmethod. The results showed that all extracts could reduced uric acid level of rats. The decreasing potency of uric acidlevel was equal to doses increase, so the best result that can reduce uric acid level was J. gandarussa extract at a dose5.2 g/ kg bw. This results indicated that J. gendarussa leaves extract may be effective for the prevention and thetreatment of hyperuricemia.

- Abstract
Hyperlipidemia is a condition of abnormally high lipids levels in the blood which has been ranked as one of the greatest risk factors contributing to prevalence and severity of coronary heart disease. The available antihyperlipidemic drugs have been associated with some side effects however, herbal management of hyperlipidemia are relatively safe, cheap and readily available. P. conophora is an edible plant consumed in Nigeria as snack and speculated to have beneficial effect on blood lipid profile. The present study evaluates anti-hyperlipidemic effect of aqueous extract of cooked P. conophora nut using in vivo and in vitro experimental models.The anti-hyperlipidemic activity was evaluated using tyloxapol induced-hyperlipidemic rats by intraperitoneal injections of Tyloxapol at a dose of 300 mg/kg body weight and high cholesterol-diet induced rats by oral administration of high cholesterol diet for 60 days. Cholesterol esterase enzyme inhibition was used for the in vitro evaluation.Aqueous extract of P. conophora at varying doses, reduced the elevated lipid parameters in both models; the dose of 500 mg/kg showed comparable hypolipidemic effects with standard drug (Simvastatin) at 10 mg/kg (P<0.01). The extract also inhibited cholesterol esterase enzyme with IC50 value of 129.30±0.10μg/ml while Simvastatin with IC50 value of 51.42±0.13μg/ml. Preliminary phytochemical analysis revealed the presence of; Flavonoids, saponin, cardiac glycoside, alkaloids, tannins, steroids and reducing sugar.P. conophora extract exhibited strong hypolipidemic activity and the dose of 500mg/kg demonstrated equipotent activity as the standard drug; Simvastatin 10mg/kg. The extract also showed inhibitory activity against pancreatic cholesterol esterase enzyme; hence can be used to limit absorption of dietary cholesterol, prevent and treat hyperlipidemia.

- Abstract
Evidence based use of herbal medicines has a positive implication for both users and society. In this study, component plant materials of a traditional Ghanaian polyherbal skin product comprising Eugenia caryophyllata, Zanthoxylum zanthoxyloides Tridax procumbens, Psidium guajava and Alchornea cordifolia and used in the management of superficial skin infections was evaluated to establish their contribution to the overall therapeutic activity of the product. Each of the five (5) plants was subjected to an in vitro antimicrobial assay using the microtitre broth technique followed by an interactive combination assay for plants demonstrating noteworthy antimicrobial activity (MIC ≤ 1.0 mg/ml). Test strains included Staphyloccocus aureus, Candida albicans, Trichophyton rubrum, Epidermophyton floccusum and Microsporum canis. Eugenia caryophyllata, Zanthoxylum zanthoxyloides and Alchornea cordifolia showed better activity than Psidium guajava, Tridax procumbens and the Total Crude Extract (combination of the 5 extracts). The binary combination of Eugenia caryophyllata and Alchornea cordifolia indicated synergistic and additive activity against all the test strains. An improved biological activity was also observed when a mixture of the two (2) plants at a ratio of Eugenia caryophyllata 60 % (w/w) and Alchornea cordifolia 40 % (w/w) was assayed. A follow up pilot clinical study established that this new recipe was clinically effective but of lower therapeutic effect compared to the original product. In conclusion, the original formulation of the product may be preferred because of the shorter duration of treatment which reduces the risk of harms and cost of treatment.

- Abstract
Acridone is a unique naturally occurring alkaloid known to associate with several biological activities. 2,3-dimethoxy-10-methyl-10,8a-dihydroacridin-9(8aH)-one (4) and its precursor 2-((3,4-dimethoxyphenyl)methylamino)benzoic acid (3) were synthesized and investigated for potential antioxidant and inhibitory activity against acetylcholinestrase. The synthetic pathway involves reaction of 2-(methylamino) benzoic acid (1) with 4-chloro-1,2-dimethoxybenzene (2) in presence of CuO and K2CO3 to give the precursor 3. Subsequent, cyclcondensation of 3 with Conc. H2SO4 afforded the anticipated acridone 4. Furthermore, the dimethoxyacridone derivative 4 showed potent antiacetylcholinesterase (ACHE) activity at (100 uM) with IC50 = 9.25 uM that is as potent as the reference drug rivastigmine. Assessment of total antioxidant activity of compounds 3 & 4 in comparison to known standard compounds revealed the following order: α-tocopherol > Acridone 4 > trolox > butylated hydroxyl anisole (BHA) > butylated hydroxyl toluene (BHT) > compound 3. Molecular docking characteristics of 3 & 4 within the active site of AChE (PDB: 1ACJ) co-crystallized with 9-amino-tetrahydroacridine (Tacrine) have been studied. Interestingly, the results revealed comparable binding poses to the co-crystallized ligand and demonstrates good correlation of the binding energy (DG) with the observed IC50-values. This finding suggests that compounds 3 & 4 exhibit good antioxidant effect and inhibition of acetylcholinesterase, which might provide profitable candidates in management of Alzheimer’s disease.

- Abstract
Background: It has been reported by the Ministry of Health that the prevalence of wounded and worsening events is increasing in Indonesia. This situation requires more intensive attention. Eel mucus has been an alternative treatment of wounds in some parts of Indonesian society since ancient times. Aim and Objectives: To explore the effectiveness of eel mucus ointment as a natural wound healing product. Material and Methods: This experimental study used 45 mice divided into 3 groups; 15 mice in each group. All mice were aseptically wounded 1.5 cm on their anterior region of back skin using a sterile scalpel, and then treated with placebo, povidone iodine ointment, and with eel mucous ointment (Belutidine). On the third, sixth and ninth day, the mice were sacrificed. Data on wound length were taken on 9th day. Microscopic data of histologic slides collected were: number of neutrophil, mono-nuclear, neo-vascular and fibrosis cells. Data were analyzed using statistical analysis. Results: There was a significant difference in wound length between the groups (p = 0.008). The number of mono-nuclear cells on the third day was different significantly among the groups (p = 0.008). There was no significant difference of the overall observed cells on day 6 and there was a difference in mean number of neutrophils and fibrosis on day nine (p < 0.05). On day nine, the group treated with eel mucus ointment had the highest number of mean of neo-vascular and fibrosis cells. Conclusion: Eel mucous ointment is effective for wound healing.
