Background: The rapid loss of kidney function is known as nephrotoxicity. The harmful effects of medications may cause this. Amikacin-related nephrotoxicity is an excellent illustration of such a case. Amikacin is a synthetic aminoglycoside that works against the majority of gram-negative bacteria and, in some circumstances, can be harmful to the kidneys. One of the many methods used to prevent or decrease this toxicity is the use of antioxidant substances with amikacin. Beta carotene is an antioxidant carotenoid pigment.The aim of the current study: is to illustrate the ameliorative effect of beta carotene against the nephrotoxicity caused by amikacin when given before or during the treatment of amikacin. The study also evaluates the nephrotoxicity evoked by amikacin.Material and Methods: Five groups of animals were used (seven rats in each group): the control group, the amikacin group, the beta carotene group, the beta carotene with the amikacin group, and the group given beta carotene first, then added amikacin later together with the beta carotene.Results: The results of the current study demonstrate that when comparing the amikacin-treated group to the control group, there was a significant elevation (p ˂ 0.05) of serum creatinine and urea levels. The results also showed that when comparing the amikacin -treated group to the group treated with beta carotene during amikacin treatment for 14 days, there was a significant reduction (p ˂ 0.05) in serum creatinine and urea levels. Furthermore, in comparison of the amikacin -treated group to the group treated with beta carotene only for 9 days and continued with amikacin for 14 days, there was a significant reduction (p ˂ 0.05) in serum creatinine and urea levels. Also, there were significant decreases (near normal) in serum creatinine and urea. Histological findings confirmed these findings; there was damage to renal tissue in the amikacin -treated group, whereas groups treated with beta carotene and amikacin showed improvements in histological images.Discussion and conclusion: According to the results of renal function tests and histological findings, treatment with AMK only causes renal toxicity in rats, and when rats are treated with BC before and during AMK treatment or even only during AMK treatment, BC can prevent this renal toxicity by decreasing serum urea and creatinine levels, which, in agreement with the previous study, leads us to conclude that BC offers significant protection against AMK-induced nephrotoxicity, The results also showed the efficiency of two methods of administration of beta carotene in giving the required protection against renal toxicity (not preferring one method over the other).

Background and objectives: Atherosclerosis is the underlying pathology of ischemic heart disease. There are many aggravating metabolic and oxidant parameters which are participating together overwhelming the pathology of vascular stenosis. Adipokines play a positive metabolic effect in healthy individuals and oxidation reaction greatly impacts the lipid metabolism and might negatively impact the condition. In the present study, we aimed to characterize the level of adiponectin, obestatin, and redox parameters in atherosclerotic patients.Methods: Serum was collected from atherosclerotic patients and froze to be ready for analysis.Results: The results indicated that hyperlipidemia significantly reduced adiponectin, obestatin, and antioxidant enzymes (catalase, glutathione, glutathione-S-transferase, and glutathione peroxidase) together with a significant increase in oxidant byproduct (malondialdehyde) and modulated lipid parameters (cholesterol, triglyceride, and high-density lipoprotein).Conclusion: The study concluded that atherosclerosis is associated with reduced antioxidant enzymes, obestatin, and adiponectin levels and increased lipid levels. These parameters play a great role in the patho-logical status of coronary stenosis.

Background: Carbonated beverages are very popular worldwide. Carbonated beverage consumption vast increase raises great health concerns regarding their effect on calcium homeostasis besides obesity and renal function. Carbonated beverages sugar content, caffeine, and acidulant all can affect in a way or another calcium absorption, metabolism and excretion. The latter has direct effect on teeth, bone and general wellbeing. This study aims to reveal the effect of sub-chronic intake of carbonated beverage on urinary pH, crystalluria, calcium excretion.Methods: 21 healthy volunteers have been recruited in this study (9 males and 12 females) abstain for any carbonated beverages for at least the previous 4 weeks before participating in this study. Urine has been collected over 24 hours, the next day each volunteer has to drink 250 ml of carbonated beverage (Pepsi®) daily for 3 weeks. On the last day, urine was collected again over 24hr. pH, crystalluria, and calcium in urine have been measured.Results: Urine pH and crystalluria after 3 weeks' intake of 250 ml of carbonated beverage did not statistically differ from urine pH before the intake. Although, there was a trend toward reduction in pH and an increase in crystalluria. Total calcium excretion in urine increase was statistically significant when compared with calcium excretion at the study beginning.Conclusion: The regular intake of carbonated beverage (Pepsi®) increase calcium excretion. Thus, it may be advisable to increase the intake of milk or other dairy product to overcome the adverse impact of carbonated beverages.

Background and objectives: hyperlipidemia is the hallmark of cardiovascular diseases, namely hypertension, ischemic heart diseases, and strokes. Treatment should be satisfactory to tackle the lipid disorder and maintain the circulatory normal lipid profile. Many factors/cofactors coordinate to maintain lipid levels within normal to avoid subsequent hazards associated with hyperlipidemia. Coenzyme Q10 is a ubiquitous endogenous biomolecule that plays an important biological role in the lipid catabolic pathway. The goal of the study is to define the role of Coenzyme Q10 in hyperlipidemic mice model induced manually.Methods: to do so, a diet based hyperlipidemia state was induced in mice and they were distributed into different groups to conform with our study objectives. A Coenzyme Q10 treated group was compared to the negative control group and the positive control group was used as well.Results: The biochemical and histological outcomes declared that Coenzyme Q10 has important lipid-reducing effects which are parallel or even superior to lipid reducing drugs (e.g. Rosuvastatin). Conclusion of the present study addressed the lipid-lowering properties of Coenzyme Q10 in a newly induced hyperlipidemia mouse model bestowing the use of Coenzyme Q10 as add-on adjuvant therapy in a high-risk group or as a monotherapy in a prophylactic group.
Introduction: Coronavirus pandemic is currently a global health concern with no established treatment guidelines. The aim of the present study was to determine the therapeutic effectiveness of hydroxychloroquine combined with azithromycin in patients with positive coronavirus disease 2019 (COVID-19) admitted to the hospital with severe dyspnea, as well as the incidence of occurrence of adverse effects.Methods: It was intended to utilize a retrospective clinical study of approximately 250 adult patients admitted to the ALSALAM Teaching Hospital in Mosul city with mild to moderate COVID-19 in order to evaluate treatment efficacy in combination with clinical and biochemical findings. Two groups were involved in the research. The first patient group consisted of 250 people who got hydroxychloroquine in conjunction with azithromycin, while the second untreated control group consisted of 100 individuals who received no medication as part of the research.Results: Baseline parameters (clinical and biochemical assays) did not vary substantially among the two groups. Patients in the treatment group were hospitalized at a rate of 30%, compared to 27% in the untreated control group (P<0.001). Between groups, there were no statistically significant changes in mortality,non-invasive oxygen demand, or hospitalization duration. Biochemical and Clinical outcomes were comparable between those receiving hydroxychloroquine with azithromycin and those do not receive any medication.Conclusion: This treatment regimen was shown to be not affective in mild to severe positve COVID-19 hospitalized patients and was associated with a small number of mild to moderate clinical adverse effects.
Smart hydrogels are special type of hydrogels that undergo solution-gelation transition in response to alterations in the environment. Solution-gel transformation is brought about through either physical or chemical cross-linking that occur between the hydrogel chains. Various stimulating factors have been identified to be responsible for the change in the physical state of the intelligent hydrogel. The most important triggering factors are the temperature, pH, ions, electrical signalling, magnetic field, glucose, light and others. Each of these stimulating factors can trigger the swelling of the hydrogel through unique mechanism. Many of these triggering factors are characteristics of the biological systems which make the smart polymers quite beneficial for different biomedical applications. Numerous natural and synthetic polymers have been distinguished to act as smart materials. These polymers impressed the scientists to use them in many biomedical and industrial applications such as drug delivery systems, gene therapy applications, tissue engineering and many other applications.
Every year many drug molecules discovered to be effective in treatment of many diseases, however not all of these drugs succeed in reaching the market. One of the main reasons for such failure is the lipophilicity or low water solubility of these chemicals which results in poor bioavailability. Nanoemulsion has the ability to deliver these drugs in an efficient way. Nanoemulsion, which is usually o/w emulsion can incorporate this lipophilic drug into nanolipoidal droplets. However, the difficulty in applying liquid dosage form can be overcome by using nanoemulgel system. Nanoemulgel considered as a suitable way to deliver lipophilic drugs through topical route. This review tries to highlight the importance of nanoemulgel as a drug delivery system. The components of the systems have been explored and the methods of preparations including high energy methods and low energy methods have been discussed. Different methods were used in characterization of such delivery system; all of these methods and techniques were reviewed briefly. Finally, the recent researches about different applications of emulgel in local delivery or systemic delivery has been discussed. To conclude, the nanoemulgel applications in drug delivery is very promising and many products will find their way to the markets soon.
The ventricular septal defect (VSD) is a congenital lesion characterized by the presence of an opening between cardiac chambers. The treatment might involve medical therapy to control symptoms or in certain cases, surgical resuscitation might be required.Objectives: The study was conducted to establish a database about the prevalence and pattern of VSD and their prognosis in children referred to by echocardiography in Ibn-Sena Teaching Hospital over the period of March 2019 to January 2020. Method: The present study is a prospective descriptive study conducted on all patients diagnosed with cardiac lesions revealed by echocardiography. The sample included in the study involves newborns (day 1) to 14-years-old children.Result: Out of 500 children included in the study; most of these cases were cyanotic congenital heart lesions and out of which two-third were perimembranous defects.Conclusion: The study concluded a higher prevalence of non-cyanotic lesions and peri-membranous type is the commonest VSD lesion.
Introduction: Symmetrical and Asymmetric dimethyl-L-arginine were previously discovered in urine, the present study explored the link between acute kidney injury (AKI) and modulation in the level of these biomarkers.Methods: Ninety volunteers were recruited in the current study, sixty of them were dialysis-dependent AKI patients, their ages ranged between 29-70 years, 13 were diabetic and 47 were non-diabetics patients. Thirty healthy subjects were recruited as a control group. Blood urea, serum creatinine, uric acid, glucose, lipid profile, albumin, hemoglobin, levels were measured using an automated analyzer (SK3002b). Asymmetric dimethyl-L-arginine (ADMA) and symmetric dimethyl-L-arginine (SDMA) serum concentrations were measured using ELISA.Results: The findings of the current study demonstrated a significant decrease in hemoglobin and serum albumin levels alongside an increase in the serum creatinine, uric acid, and serum triglyceride (TG) in the patients when compared to the apparently healthy controls. Serum concentrations of ADMA and SDMA were significantly lower in healthy controls compared to the patients. Conclusion: These data confirm the assumption which assumes that both, ADMA and SDMA serum levels are sensitive markers of reduced renal function and serum SDMA is more sensitive than ADMA in dialysis-dependent AKI patients.
The present study has shown the screening test of Hawthorn fruits (Crataegus spp.) using crude hydro-alcoholic extract and in vitro antimicrobial activity of extracted flavonoid which has shown more antibacterial activity than crude extract with minimal inhibitory concentration (MIC) values ranged from 5% to 2.5%. The amount of total flavonoid and antioxidant activity of Hawthorn fruits (Crataegus spp) in various concentration extracts and antioxidant activities of different concentration extracts were determined by radical scavenging by 2, 2-diphenyl-1-picrylhydrazyl (DPPH*). The output showed that the contents of flavonoid were found to be 0.386 mg quercet in equivalents (QUE/g). Dried extract displayed remarkable antioxidant activity according to (DPPH*) assays.
