The synergistic relationship between Aminoglycoside Antibiotics and Zoledronic acid (ZOMETA) drug in their effect on Bacillus cereus and Staphylococcus aureus bacteria.
type: item
description: In this study, we investigated the synergistic relationship between some antibiotics from the aminoglycosides functional group, which were Chloramphenicol (C30µg), CEFOTETAN (CTT30µg), AMIKACIN (AK30) and CEFAMANDOLE (MA) and the chemical drug Zoledronic acid (ZOMETA 4g) which is used in Cancer treatment. This study focuses on their Effect on Gram-positive bacteria Bacillus cereus and Staphylococcus aureus using disc diffusion method for anti-susceptibility test, and spectrophotometry method for bacteria cells count. The results of the Zoledronic acid anti-susceptibility test showed that it had no effect on both bacteria. However, the antibiotic's anti-susceptibility test on B. cereus showed resistance to the antibiotic (C30) and (MA 30), also showed the highest susceptibility pattern to the antibiotic (AK 30). while the lowest susceptibility pattern was for the antibiotic (CTT 30). While on S. aureus bacteria showed resistance to antibiotic (MA 30), with the highest susceptibility pattern to antibiotic (C 30), and the lowest susceptibility pattern to antibiotic (AK 30); The results of the synergy test (the relationship between the Zoledronic acid and the antibiotic) on both B. cereus and S. aureus bacteria showed that all antibiotics have a synergistic relationship with the drug.

A Study on the Assessment of Lead and Copper Elements in a Designated Areas of Agricultural Soil in the City of Benghazi, Libya
type: item
description: This study investigates the concentrations of lead and copper in soil samples collected from different locations, analyzing the potential contamination of heavy metals and their implications for the environment. Statistical analysis revealed significant differences in lead concentrations between the samples (ranging from 9.45 mg/kg to 24.75 mg/kg) with the highest concentration observed in sample number 6. These levels exceed permissible limits in several countries, suggesting potential soil contamination, which warrants further evaluation of the impact on plant growth and agriculture. Additionally, copper concentrations ranged from 5.65 mg/kg to 15.10 mg/L, with significant differences observed at a probability level of less than 0.001. These findings are consistent with previous research indicating that high levels of copper accumulation can lead to soil toxicity and hinder plant nutrient absorption. The study highlights the importance of monitoring and mitigating heavy metal pollution in soil to prevent adverse effects on ecosystems, agricultural productivity, and human health.

Fibrous Cerium Phosphate and its Intercalated-Urea Product as Versatile Adsorbents for Mercury (II) Removal
type: item
description: Fibrous Nano cerium Phosphate was achieved by reacting Cerium Sulphate solution with phosphoric acid at 80°C for several hours. Furthermore, Urea was intercalated into the prepared f-cerium phosphate. Techniques like Fourier Transform Infra-Red spectroscopy, X-ray diffraction, Scanning Electron Microscope, and Thermogravimetric analysis were used to characterize these products. Under various conditions, the products were examined to their adsorption capability to extract mercury (II) ions from aqueous solution. The semicrystalline nature of the phosphates was demonstrated by XRD, and the interlayer d-spacings for the cerium phosphate and urea-intercalated compounds were 10.6 and 11.3 Å, respectively. The FTIR spectra of the intercalated phosphate showed an additional peak at 1400 cm⁻¹ corresponding to C-N stretching confirming the presence of urea. The SEM showed a fibrous morphology of the cerium phosphate with a particle size of 16mm. The optimum adsorption conditions were at pH values 3.0 at a reaction time interval of 30 minutes. Pure cerium phosphate behaved differently from intercalated cerium phosphate, which consistently showed a decrease in adsorption percentage as the initial ion concentration increased. Both phosphates showed a systematic increase in adsorption percentage as the adsorbent amount increased, however, pure cerium phosphate showed greater adsorption ability than its intercalated analogue. Both Freundlich and Langmuir isotherm models were used, and their linearity curves are comparable. For pure and intercalated chemicals, the Langmuir model yielded R² values of 0.5351 and 0.7283, respectively. According to the Freundlich model, the pure and intercalated phosphates R² values were 0.5823 and 0.8649 respectively. Although a low correlation is observed, the intercalated material fit both isotherms and showed a slightly better behaviour.

Investigation of Sedimentary Microfacies and mineralogical analyses of the Coastal Rock Cliffs (Wadi al-Zaytoun) in the Al Jaghbub, Al Faidyah, and Abraq Formations, NE Libya
type: item
description: This study analyzes the bulk mineralogy and microfacies of the Al Jaghbub, Al Faidyah, and Abraq Formations, NE Libyaalong the Eastern Libya coastline using X-ray diffraction (XRD) on five samples from different geomorphological units. The results show a dominance of terrigenous minerals—mainly quartz, albite, and kaolinite—alongside carbonate minerals (calcite and dolomite) and evaporite minerals, particularly halite. Quantitative analysis reveals significant mineral proportion variations Al Abraq Formation contains high levels of dolomite (87.9%) and albite (7.9%), while Al Faidiyah Formation is predominantly calcite (98.9%). Halite appears in All Formations, indicating evaporative processes, and kaolinite in Sample 3 suggests fluvial influence or older sediment reworking. Microfacies analysis, conducted on thin sections from Wadi al-Zaytoun, identified five types: (1) dolomite wackestone, (2) foraminiferal bioclast packstone, (3) dolomitic wackestone, (4) foraminiferal bioclastic packstone, and (5) echinoidal, foraminiferal, algal packstone. These microfacies display features indicating deposition in various environments, ranging from arid tidal flats to high-energy shallow marine settings. Diagenetic processes such as the replacement of micritic matrices with sparry calcite and the formation of coarse dolomite crystals highlight the roles of fluid migration and redox fluctuations.

Assessment of Juniperus Phoenicea L. Seedling Produced via Tissue Culture Using RAPD Analysis
type: item
description: Woody plants are more difficult to reproduce than other plant species found in nature. In addition to seed dormancy, which is caused by inhibitors in the embryo, endosperm, and/or testicle, Phoenicia, like other juniper species, does not exhibit a high rate of plant production by germination of seeds. This research's primary goals were to propagate Juniperus phoenicea L. (J. phoenicea) using tissue culture by identifying a promising protocol for utilizing kinetin (0.5 mg/l-1 with Murashige and Skoog 1962, MS), Rugini Olive Medium 1984, ROM, and Lloyd and McCown 1980, WPM to break the secondary dormancy of seeds. Additionally, RAPD fingerprints were used for molecular analysis to determine the total genomic DNA of the parent plant compared to the in vitro plant obtained. The RAPD-PCR products they obtained demonstrated a high percentage of polymorphism resulting from using BA-K5 as a primer compared to BA-K2. The results showed that the medium (WPM) supplemented with 0.5 g/l⁻¹ kin gave the highest significant increment for germination percentage (60%), while MS gave the lowest germination rate (8%). The study concludes that the in vitro culture method for zygotic embryo germination may be a viable way to overcome the challenges posed by poor juniper germination rates and boost seed propagation

Effect of hypoxia on release TNF alpha by dendritic cells and macrophage derived from myeloid cells of mice
type: item
description: Hypoxia is low levels of oxygen and is a common feature during inflammation associated with numerous inflammatory diseases and infections. Dendritic cells and macrophages are significant immune defensive cells with a range of functions that include phagocytosis, secretion and release of an extensive kind of proteins including cytokines and chemokines, and are typically found in areas where oxygen availability is low, especially during inflammation. Tumor necrosis factor type alpha (TNF α) is a cytokine that is expressed by various cell types including macrophages, dendritic cells, and other non-immune cells against infections. It is an important pro-inflammatory cytokine that regulates inflammatory cells and responses. This study focused on comparing the effects of hypoxia on the release of TNF alpha levels by dendritic cells and macrophages derived from myeloid cells of C57BL/6J mice in vitro using the ELISA test. Hypoxia is used because of the associated changes in the living body of the mouse. Non-stimulated macrophages and dendritic cells derived from myeloid incubated in parallel in hypoxia and normoxia showed the production of TNF-α in both conditions; however, both dendritic cells and macrophages released more TNF-α in normoxia than in hypoxia. The production of TNF-alpha was higher in dendritic cells compared to macrophages. In brief, the comparisons between normoxia and hypoxia on the release of TNF alpha by dendritic cells and macrophages derived from myeloid cells of non-stimulated mice were shown.

Sulphur, Organic Carbon, Organic Nitrogen, Iron Relationships and Diagenesis of Black Shales in Tenom and Ranau Regions , West Sabah, Malaysia.
type: item
description: The sediments investigated in this paper constitute part of the Temburong and Trusmadi formations outcropping in the Tenom and Ranau area located in the Western part of Sabah state, Malaysia. The aims of this paper were to analyzed and determine the various forms of (organic and inorganic sulphur), organic carbon, organic nitrogen, iron, total sulphur, and pyrite sulphur which was determined in two organic fractions (bitumen and kerogen) as well as in the total rock of these carbonaceous sediments, and also to assess the relationships between C, S, and N content in the early stage of microbial diagenesis of the studied black shales. The bulk geochemistry concentration, especially the C-S relationships, showed the important role of reactive iron in controlling the extent of pyrite formation. The high values of the degree of pyritization (DOP) which ranges from 0.99 to 1.0 suggested that iron has been exhausted by pyrite formation (i.e. iron- limited conditions) in all the study samples. The reduced sulphur in these study samples increases with burial depth and time. This pattern suggested the continuous diagenetic addition of reduced sulphur under conditions where the time and depth of burial are related. Kerogen appears to be uniform in N and S content, but both components vary in bitumen. N contents in bitumen show no covariance with any other parameters, but bitumen always has a much higher C/N ratio than kerogen. The presence of pyrite framboids is an additional evidence for poorly oxygenated (anoxic) bottom waters depositional environment.

Towards a Better Knowledge of the Neurotoxic Effects of Occupational Exposure to Organic Solvents on Human Health: A Review Study
type: item
description: This review examines existing studies on the effects of exposure to the organic solvent (OS) on human health, whereby the focus is on its associations with dementia, Alzheimer's and chronic-solvent-induced encephalopathy (CSE). OSs also known as volatile organic compounds (VOCs), are widely used in industries such as pharmaceuticals, construction, and manufacturing due to their ability to dissolve non-aqueous substances. Despite their utility, many OSs, including benzene, toluene, and hexane, are highly toxic and pose significant health risks, particularly to workers in high-exposure occupations. Prolonged exposure to these solvents has been linked to severe neurotoxic effects, including CSE, cognitive impairments, and neurodegenerative diseases such as dementia and Alzheimer’s disease. The lipophilic nature of OSs allows them to accumulate in lipid-rich tissues, including the brain, disrupting neurological functions and contributing to long-term cognitive decline. This research reviews the mechanisms of OS-induced neurotoxicity, emphasizing the role of volatility, lipophilicity, and metabolic pathways in determining bioavailability and health impacts. It highlights the disproportionate burden of exposure on vulnerable populations, such as migrant workers and those in low-resource settings, and discusses the economic and social implications of solvent-related cognitive disorders. Conflicting evidence and research gaps are addressed, underscoring the need for large-scale, longitudinal studies to establish definitive causal relationships between solvent exposure and cognitive decline. To mitigate these risks, it recommends stricter regulatory measures, improved workplace safety protocols, enhanced worker education, and ongoing health monitoring. By prioritizing proactive interventions, industries can reduce occupational solvent-related health risks, protect vulnerable workers, and promote safer work environments. This review underscores the importance of balancing ind…

Synthesis, Characterization and Application of Goethite as an Adsorbent for Uranyl (VI) ion from its Aqueous Solutions
type: item
description: Nano goethite was synthesized via chemical precipitation, characterized, and utilized in batch adsorption of uranium (VI) in aqueous solution. This study aims to investigate whether a synthetic goethite could extract uranium (VI) from aqueous solutions, and to study the adsorption isotherm models. In this work, goethite (α-FeOOH) was synthesized using Atkinson et al.'s approach, which was utilized as an adsorbent. It was essential to characterize this adsorbent material. The prepared material was characterized using Fourier transform infrared (FTIR) and X-ray diffraction (XRD). Investigation and optimization have been done on different factors that may influence uranium (VI) adsorption, such as pH, initial ion concentration, and adsorbent amount. The ideal parameters that were found were then applied to actual effluents that contained uranium (VI). The results demonstrated that more than 95% of the uranium (VI) was removed. Utilizing the Langmuir, Freundlich, and Temkin models, the data shows strong agreement with the three models. According to the Langmuir isotherm model, the highest sorption capacity of goethite was 33.3 mg/g, the Langmuir constant was -7.77 L/mg, and the separation factor was 1.29x10-3. The Freundlich constant was found to be 28.31 (mg/g)*(L/mg)1/n, and the adsorption intensity was 2.09. The was also in agreement with the Temkin model, which shows the bT equals 68.75 joules/mol and the KT equals 3.89 L/mg. The correlation constants were in the order of 0.982 > 0.961 > 0.872 for Langmuir, Freundlich, and Temkin, respectively, explaining that the three models show favorable fittings.

Sustainable Use of Silk Vine Roots(S-VPR) as Low Cost Adsorbent for the Removal of Methylene Blue Dye from Its Aqueous Solution
type: item
description: This study examines the adsorption of methylene blue dye from an aqueous solution using silk vine roots derived from dairy powder. The adsorbent material was utilized in its natural state, without any chemical or physical treatment. The adsorption process was conducted under different conditions, including pH, adsorbent weight, initial dye concentration, and contact time at room temperature. The adsorption capacity exhibited an increase (49.9 mg/g), whereas the adsorbent weight and initial concentration increased until equilibrium was reached within 20 minutes. The adsorption process followed second-order kinetics and displayed compatibility with the Freundlich isotherm coefficient. It was determined to be a multilayer, heterogeneous adsorption process with a maximum adsorption capacity value (qe max 49.9 mg/g). Based on the results, it can be confirmed that wild dairy (silk vine) is capable of effectively adsorbing pollutants, such as the blue methylene dye.

Parasite Contamination of Fresh Leafy Vegetables in Benghazi, Libya.
type: item
description: Background: Raw vegetable consumption can be a primary pathway for the spread of food-borne parasite illnesses, despite the fact that fresh vegetables offer significant nutritional value to people. Thus. This study's goal was to investigate whether parasites are present in veggies that are frequently eaten in Benghazi city, Libya. Method of the study:- One hundred and fifteen types of vegetables. lettuce, mint, parsley, green onion, and watercress 30 pieces of each were included. The sediments experienced analysis using iodine and modified smears stained with Ziehl- Neelsen, while data SPSS version 20 statistical software was used for the analysis. Results:- It was discovered that 90% of the samples that were inspected contained parasite eggs, cysts, and larvae. With a contamination percentage of 100%, lettuce was the most contaminated vegetable, and parsley had the lowest contamination rate (80%). The parasite with the highest prevalence rate was Entamoeba histolytica/ dispar cyst (71.1%), Giardia Lamblia cyst and Hymenolepis nana eggs (13.3% each of them), Taenia. Saginata eggs (11.11%), Ascaris eggs and Entamoeba. Hartmanni cyst (6.67% each of them), but it was discovered that the Strongyloides larvae only occasionally appeared (6.67%). Conclusion:- Benghazi City leafy vegetables had a very high parasitic rate of contamination. Therefore, eating such vegetables without thoroughly cleaning them promotes the spread of parasitic diseases, which provide a serious risk to health for those in Libya.

Evaluation of the ability of endemic herbal extracts to bio-control some plant pathogenic bacteria: (Araceae of Libya).
type: item
description: Potentially control of plant diseases in the future can occur by utilizing endemic plant extracts to provide biotic and abiotic environmental conditions that are beneficial for host development and growth which are adverse to pathogen reproduction and evolution. The present study reports the antibacterial activities of three species of endemic herbs of Araceae. The antibacterial activity was determined by methanol and acetone extraction of aerial and underground parts of three endemic herbaceous species in Libya; Arisarum vulgari, Arum cyreniacum and Biarum bovei. The test was conducted by Screening using the disc diffusion technique, against Two various species of plant-pathogenic bacteria; Agrobacterium spp. and Erwinia spp. According to this study, the most effective way to manage plant-pathogenic bacteria was tuber extracts, especially B. bovei tubers. A. cyreniacum tuber extracts also showed good efficacy, while A. vulgaris extracts were the least effective. On the other hand, the majority of the examined extracts had the greatest impact on Erwinia spp. This is the first report to highlight the potential of all species of endemic herbs of Araceae family of Libya in the bio-control of plant pathogens. Thus, endemic herbs of Araceae can be considered to possess strong germicidal properties against plant disease-causing Agrobacterium spp.and Erwinia spp.

Theoretical Investigation on Molecular Structure-Chemical Quantum Calculation of 7-Methyl-1,2,3-Triazole[4,5-c]Pyridine (Computer Simulation Program)
type: item
description: Theoretical investigation of 1H- and 3H-7-methyl-1,2,3-triazole[4,5-c]pyridine tautomers and chemical quantum calculation have been studied using density function theory (DFT) (PED, optimized bond lengths and angles) at the B3LYP/6-31G(d,p) level. The result reveals Optimized bond lengths and angles in good agreement with X-ray data of other triazole-pyridine compounds. The result of chemical quantum calculation reveals that the vibrational characteristics of the triazole compound display several distinct patterns that remain almost unchanged in the vibrations of compounds containing the same structure. The vibrational characteristics of the triazole-pyridine system show distinct patterns that are consistent across similar compounds with the same core structure. The findings highlight the transferability of vibrational patterns in triazole-pyridine systems, which is useful for spectroscopic identification and further chemical design.

Mineral Composition of Coastal Landforms in Wadi Al-Suwani at Al-Bardia Region, East of Tobruk City, Libya
type: item
description: This study investigates the mineralogical composition of coastal geomorphological units, including sabkhas, rock cliffs, and beach sands, along the Wadi Al-Suwani shoreline near Burdi village in east of Libya. The research aimed to characterize these landforms, focusing on their geochemical and mineralogical properties, to better understand the processes shaping this unique coastal landscape. A total of fifteen samples were collected during field trips in August and September 2022, spanning various geomorphological units such as sabkhas, rock cliffs, and beaches. X-ray diffraction (XRD) analysis revealed that intertidal sabkha sediments predominantly contain terrigenous minerals like quartz (40.7%-69.7%), microcline (34.6%-39.0%), and albite (7.7%-13.7%), with minor occurrences of carbonate minerals such as calcite (9.5%-30.6%) and dolomite (1.3%-5.4%). The supratidal sabkha sediments were primarily composed of quartz (45.7%-69.7%) and lesser amounts of microcline and calcite, while halite was notably absent. Beach sands exhibited a mineralogical profile dominated by quartz (41.2%-78.2%) and calcite (19.1%-50.4%), with traces of dolomite and hematite. In contrast, the rock cliffs of the Al-Abraq, Al-Faidiyah, and Al-Jaghbub Formations were overwhelmingly composed of calcite (83.4%-97.9%), indicative of their shallow marine origin, with minor quartz and halite content. The findings underscore the complexity of depositional processes in the region, shaped by a combination of terrigenous input, marine biogenic activity, and evaporative conditions. This research provides valuable insights into the coastal geomorphology of the Al-Bardia region, with broader implications for understanding similar coastal environments globally.

  value: Introduction Diabetes is a common chronic metabolic disease, resulting from hyperglycemia, which is caused by a defect in insulin secretion or insulin action or both or the amount secreted is large, as in some obese individuals (Liu et al., 2015). Type 1 diabetes mellitus (T1DM) occurs as a result of the inability of the beta cells in the pancreas to produce insulin in sufficient quantities or their complete cessation of producing insulin. It is considered one of the most dangerous types and occurs in childhood and at the beginning of adolescence (Cernea and Herold, 2010). It can occur due to nutritional, genetic and environmental factors or due to better economic and social status and urbanization (Al-Abadi and Al-Najafi, 2018).T1DM affects millions of children around the world annually, and is on the rise among young children and increasing in European, Eastern and Arab countries, and their incidence is expected to rise to 3% annually (Guariguata, 2011). High blood sugar levels above the normal range for a long period of time cause several chronic complications and serious developments, such as retinopathy, nephropathy, peripheral or central nervous diseases, and Charcot joints with severe gastrointestinal disorders (Cooke and Plotnick, 2008). Vitamin D is a group of fat-soluble secosteroids that plays a major role in the metabolism of calcium and phosphorus (Adamczak et al., 2014), and it can be obtained from foods from animal sources, and from foods from plant sources (Dominguez et al., 2021). It is also produced by the skin when it is exposed to direct sunlight. When vitamin D enters the body, it is not in the active form and is called hydroxyvitamin. Ultraviolet B rays stimulate cortisone in the skin and the formation of raw vitamin D. The blood transports it to the liver to be activated into hydroxyvitamin D(DOH 25), and this compound has a direct effect on most of the body’s cells that receive it and convert it into the active vitamin compound, and part of i…

The cardiovascular function and growth of the developing embryo exposed to nicotine during the early stages of chicken embryo.
type: item
description: Congenital malformations, present at birth, can be caused by genetic factors, environmental influences, or both. Nicotine exposure during pregnancy, whether due to passive smoke exposure or active smoking, is a significant environmental factor contributing to congenital malformations. Nicotine imitates acetylcholine, a natural chemical in the body, and its consumption by expectant mothers leads to growth delays, nervous system and cardiac abnormalities, and other abnormalities. The aim of this study is to investigate the impact of nicotine on the early stages of embryonic development. The study focused on observing general morphological abnormalities in the development, and alterations in heart rate using domestic chick Galls galls embryos. Fertilized eggs were sterilized with 70% ethanol and then injected with three concentrations of nicotine solution (0.1, 0.3, and 0.5 mg/ml) on day zero before being placed in an incubator set at a temperature range of 37.5 - 38 Co. The current research indicated the effects of nicotine on the heart rate (HR) of chicken embryos treated at different stages, HH19 (Day 3), HH27 (Day 5), and HH36 (Day 10), with nicotine solutions in a decrease in HR. This suggests that nicotine has a notable effect on the heart rate of chicken embryos at various developmental stages.

Evaluation of Pomegranate Peel as Bioadsorbent for the Removal of Lead Ions from Aqueous Solutions Using Phytoadsorption Technique
type: item
description: Removal of toxic heavy metals from ecosystems is a challenge. Looking for green solutions is always required. Phytoremediation is one of the most powerful, efficient, and sustainable methods. However, phytoadsorption approach was emerged in the last two decades as a potential, cheap, and benign method for the clean up of contaminated aquatic systems from heavy metals. We have investigated the potential of dry pomegranate peels as biosorbent to remove lead ions from their aqueous solutions using the phytoadsorption technique. Different amounts of the dead biomass (5.0, 2.0, and 0.5 g) at varied shaking rates of 400, 600, 800 OSC/min and three periods of contact time were applied. The resulting observations of all experiments showed that the dry pomegranate peels were able to remove up 91.1% of Pb2+ ions from their 1000-ppm aqueous solutions at room temperature and neutral pH. In addition, the pomegranate peel as a bioadsorbent has showed an adsorption capacity up to 96.1 mg/g. Consequently, the pomegranate peels can be used as potential bioadsorbents for the removal of lead heavy metal from the contaminated aquatic systems.

type: item
description: The area of saline effected soils is increasing worldwide. Salinity significantly influences plant growth and yield. However, dry yeast (Saccharomyces cereivisiae) solution may play a role in alleviating salinity stress on faba bean (Vicia faba L) plants. Therefore, the aim of this study was to investigate the ability of dry yeast solution on reducing the negative effect of salinity on bean plants. In complete randomized design with four replicates in two factors, this study was conducted. Faba bean plants were grown under saline and non-saline conditions (0 and 120mM NaCl), treated with and without yeast solution (10g/L). The results indicated that salinity stress 120mM NaCl significantly (p<0.001) decreased most of studied growth and yield parameters such as plant height, number of branches, number of leaves, leaf area, number of pods plant-1 number of seeds pod-1, weight of 10 seeds, dry weight and seed yield. On the other hand, the result shown that the application of 10g/L of yeast solution induced significant (p<0.05) promotive effects on most of growth and yield parameters in both saline and non-saline conditions. The study revealed that dry yeast solution treatment had the ability to persuade significant recovery for the reduction occurred in growth and yield traits of bean plants exposed to salinity. Overall, the study conclude that yeast can be beneficial to alleviate the injury caused by salinity stress; however, it may needed to combine it with other farming practices for optimal results.

type: item
description: The plant (Gundelia tournefortii) L (GL) was found in the temperate regions of Western Asia. Historically, it has been employed for its therapeutic attributes and biological efficacy in addressing diverse ailments. This study aimed to explore the protective role of GL. against the harmful effects of ethanol. Twenty-five male rats were split into five groups: the control group, the ethanol group, and other groups received GL. extracts containing flavonoids, alkaloids, and oils. The results demonstrated that treating the rats with ethanol caused elevating the activity of liver enzymes such as alkaline phosphatase, aspartate transaminase, alanine transaminase, gamma-glutamyl transferase, the concentrations of triglycerides, total cholesterol, low density lipoprotein, very low density lipoprotein, malondialdehyde, and reducing the concentrations of high density lipoprotein, total protein, albumin, glutathione, antioxidant enzymes activity like catalase, glutathione peroxidase, superoxide dismutase. Conversely, GL extracts reduced the toxicity of ethanol by decreasing the activity of liver enzymes, the concentration of triglycerides, total cholesterol, low density lipoprotein, very low density lipoprotein, malondialdehyde and elevating the concentrations of total protein, albumin, high density lipoprotein and antioxidant enzymes activity in the groups treated with these extracts. These results showed the hepatoprotective effects of GL extracts against ethanol which attributed to their antioxidant capacity.

Theoretical Study of the Electronic Structure of Bupivacaine and Lidocaine as Local Anesthetic Agents
type: item
description: Local anesthetics are widely used pharmaceuticals with numerous therapeutic effects that bind or inhibit other substances that bind to the beta2-adrenergic receptor (beta2 ARs). It was assumed there was a correlation between alkyl chain size of anesthetics and the degree of beta2 AR inhibition required. The findings of this research would utilize quantum computational methods, with special emphasis on DFT and TD-DFT, to study the structural and electronic properties of local anesthetics bupivacaine (B) and lidocaine (L). Important electronic parameters determined include ELUMO and EHOMO, dipole moment (μ), electronegativity (χ), electron affinity (A), chemical hardness (η), chemical softness(S), and ionization potential (I). All these parameters are very significant in understanding the reactivity and interaction of these molecules with biological systems.

Efficient Removal of Methylene Blue Dyes from Aqueous Solutions Using Various Charcoal Adsorbents: A Comparative Thermodynamic and Isotherm Study of Olive, Pine, and Commercial Activated Carbon
type: item
description: In this study, the effectiveness of various types of charcoal, including pine, olive, and commercial activated carbon, as adsorbents for removing methylene blue dye from water is evaluated. The study was conducted by preparing aqueous solutions containing methylene blue dye and using the three types of charcoal as adsorbents. The main factors affecting the adsorption process were determined through laboratory experiments, which included varying temperature, contact time, pH, and the quantity of charcoal to optimize the dye removal process. Additionally, isotherm studies and thermodynamic analysis of the reaction were conducted. The results demonstrate the successful removal of methylene blue dye by all three types of charcoal, with maximum adsorption capacities of 346.02 mg/g, 283.28 mg/g, and 406.50 mg/g for commercial activated carbon, olive charcoal, and pine charcoal, respectively. The ΔH results indicate that the adsorption process for pine charcoal and activated carbon was physical, while it was chemical for olive charcoal. This research highlights the efficiency, cost-effectiveness, and sustainability of the adsorption process using charcoal as a promising solution for reducing dye pollution in water sources, contributing to the development of sustainable water purification strategies.
