{"title":"Preparation of Idebenone as a Thermosetting Nasal Gel for Better Bioavailability and Histopathological Effect","authors":"Hussein Jaafer, Khalid Kadhem Al-Kinani","doi":"10.32007/jfacmedbagdad.2082","DOIUrl":"https://doi.org/10.32007/jfacmedbagdad.2082","url":null,"abstract":"Background Idebenone is an extensively metabolized drug with poor water solubility that is used to treat Leiber’s hereditary optical neuropathy. Objective This study aims to prepare idebenone nanoemulsion as a poloxamer-based nasal gel to overcome the extensive rate of hepatic metabolism for better bioavailability and lower histopathological effect on the nasal mucosa. Methods The formulation strategy was based on eliciting mutual concentration reduction between the nanoemulsion and the carrier gel by setting their gelation temperature between 30-32°C to overcome the mucociliary dose washout. The o/w nanoemulsions rely on cremophor EL and transcutol as an emulsifying system to stabilize idebenone-loaded lemongrass oil. The spontaneous emulsification method was used to prepare nanoemulsions that were characterized by zeta sizer while the thermosensitive hydrogels were prepared using the cold method. In-vitro dissolution test and ex-vivo permeation study through excised sheep nasal mucosa were performed to evaluate the enhanced permeation ratio, rate of permeation, and permeation coefficient. The histopathological effect of direct application on sheep nasal mucosa was studied using optical microscopy to evaluate cellular toxicity. Results The formula prepared from NE1 with poloxamer 407: poloxamer188 in concentrations 10:3% w/w respectively showed almost complete drug release in 120 minutes due to complete polymers blend erosion. Furthermore, thermosensitive nano-emulgel at a temperature of gelation 31.8°C was obtained at much lower concentrations of poloxamer 407 (10%) compared to previous studies. Nanoemulsions retained their globular size below 100nm due to further gel entrapment stabilization. Conclusions Drug permeation through excised sheep nasal mucosa elicited an increase in enhanced permeation ratio to 20.3 times and other flux kinetics parameters compared to those of IDB oil dispersion. Direct cellular toxicity showed a minor inflammatory response characterized by serous infiltration of inflammatory cells and edema. In contrast, most of the epithelial cells retained their histological characteristics compared to control slides.

Causes of death in this period are preventable like sepsis, RDS, and asphyxia, while others are not like multiple congenital abnormalities. Objectives: To study the death rate and main causes of death in the neonatal intensive care unit (NICU) of the Children Welfare Teaching Hospital (CWTH) through the period (2018-2021). Patients and methods: The death per year for the four years of the study and causes of death were collected retrospectively and analyzed for total death rate and rate for each year, sex distribution, male-to-female ratio, early and late death rate, and main causes of death. Results: it was found that the total death rate is 17.3%, male: female ratio 1.6: 1. The early neonatal death was 54.3% and the late neonatal death was 45.6%. The main causes are congenital anomalies (39%), sepsis (17.4%), prematurity (16.9%), RDS (10.8%), postoperative complications (7.5%), and birth asphyxia (1.9%). Conclusions: The death rate in the NICU / CWTH is still high despite improvement in respiratory care and the use of invasive and noninvasive respiratory support. The death rate because of congenital abnormalities was the main cause of death.

Candida species are the most common human fungal infections. Internal injuries characterize these infections because of virulence factors, such as gliotoxin, which is a fungal toxin that is thought to be antibacterial, antifungal, and antiviral. Objectives: To test the ability of Candida species obtained from clinical sources to produce gliotoxin as a virulence factor and investigate its cytotoxicity effects against some selected cell lines. Materials and Methods: One hundred and ten clinical isolates of Candida species were obtained from patients attending hospitals in Baghdad from September 2021 to March 2022. They were diagnosed and characterized by routine laboratory methods and cultures. The capability of Candida isolates to secrete the gliotoxin was tested and measured by analytical methods. The cytotoxicity of produced gliotoxin was applied against normal and cancer cell lines. Results: The 110 yeast isolates were diagnosed and identified as follows: Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata, Candida Krusei, Candida kefyr, Candida lusitaniae, Candida rugosa. Twenty-eight Candida isolates showed gliotoxin production. The cytotoxicity effects of gliotoxin were reported against lymphocytes and AMGM and AMJ13 cell lines in different concentrations. The highest cytotoxic effect was noticed in the concentration of 400 µg/mL of gliotoxin. Conclusion: The results indicated that the pathogenicity of Candida was distributed among all ages, both sexes, and several types of sources of clinical isolates. Gliotoxin had an effect on normal and cancer cells.

Inflammation of the gums and chronic periodontitis are both caused by the bacteria in the dental plaque and the herpes viruses, especially types 1 and 2 of the herpes simplex virus. Objectives: To compare the ELISA and real-time PCR as ways to detect the herpes simplex virus in breast cancer patients with periodontitis who are receiving chemotherapy. Cases and methods: In this case-control study, a total of 90 subjects (30 with periodontitis with breast cancer after receiving chemotherapy, 30 with periodontitis (without chemotherapy treatment), and 30 cases which do not have periodontitis (healthy gingiva) and without breast cancer as a healthy control group. The mean ±SD age was (51.06±8.521). Enzyme-linked immunosorbent assay (ELISA) kits were used for the analysis and Real-Time PCR to detection of Herpes simplex virus-1 in saliva samples. Results: In the present study, the incidence of HSV-1 Ag in patients having periodontitis and receiving chemotherapy was high but not significantly so compared with those having periodontitis but without chemotherapy and the healthy control group. In contrast, the result of Real-time PCR was positive (13.3%) and (10.0%), which proves the presence of HSV in most patients with periodontitis without chemotherapy and with periodontitis receiving chemotherapy but was not significant (p>0.05). Conclusion: Real-time PCR was able to back up ELISA's findings in this study. Since ELISA is more cost-effective than real-time PCR, it is advised that the first screening may be performed using ELISA, and then positive samples might be investigated with real-time PCR to confirm the presence of HSV-DNA Received:March., 2023 Accepted: June. 2023 Published: Oct. 2023","PeriodicalId":33125,"journal":{"name":"mjl@ kly@ lTb","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134935823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
