The Philosophy of Creativity, Innovation, and Technology from an Islāmic Perspective
The current study aims to shed light on the often-overlooked Islamic history and its lasting legacy, countering the dominant western discourse. It seeks to highlight the creativity, innovation, and technology that emerged from the rich classical Islamic heritage. The remarkable civilization forged by Muslim scholars and scientists across various fields of human knowledge was only made possible due to their profound belief and religious duty to promote creativity in human existence. Therefore, the current research aims to present, a philosophical study of innovation and creativity based on the Qur’ān and Sunnah supported by classical and modern Islamic literature. This study also deploys an analytical and descriptive approach to conduct an analysis of present literature on Islamic origin. Moreover, this article is a scholarly attempt to demystify the principles and values that regulate the philosophy of creativity and innovation in Islām. Additionally, it presents an Islamic view on Muslim’s existing moral issues of innovation, creativity, and technology by drawing upon the teachings and principles of Qur’ān and Sunnah. To achieve, the proposed goals of this article, many Islāmic texts that urge innovation, creativity, and pay a special concern to the talented and skilled, were consulted. Hence, the research determined that Islamic heritage has a lot to contribute to the modern conceptualization of innovative and creative human life, which motivates Muslims’ to compete with others in this regard. Consequently, there is no such thing in Islam that prevents a Muslim from excelling in technology, which brings benefits and repels harm, while following the principles and teachings of the Qur’ān and Sunnah.
Factors associated with amputation among patients with diabetic foot ulcers in a Saudi population
Objectives A prospective study was conducted at the Armed Forces Hospital, Dhahran, Saudi Arabia, between January 2015 and December 2016 to identify the risk factors associated with amputation among diabetic foot ulcers DFUs patients. Results In total, 82 patients were recruited. Fifty-five of the patients were males (67.07%), the mean (SD) age of the participants was 60 (± 11.4) years, the mean duration of diabetes was 8.5 (± 3.7) years, and the mean haemoglobin A1c was 4.8 (± 2.8)%. In Univariate analysis, older age and high white blood cell count (WBC) were factors associated with amputation (OR = 1.1, 95% CI = 1–1.1, P = 0.012; and OR = 383, 95% CI = 7.9–18,665, P = 0.003, respectively). On the other hand, an ischaemic ulcer was half as likely as a neuropathic ulcer to lead to amputation (OR = 0.5, 95% CI = 0.3–0.9, P = 0.036), and a higher Wagner’s grade was found to be protective against amputation OR = 14.5, 95% CI = 4.3–49.4, P < 0.001. In conclusion, the current study showed that although a number of factors have been described to complicate diabetic ulcers by different researchers, none of those factors were identified in our study apart from older age and high WBC.
New Ionic Liquid Forms of Antituberculosis Drug Combinations for Optimized Stability and Dissolution
Isoniazid (INH) and rifampicin (RIF) are the two main drugs used for the management of tuberculosis. They are often used as a fixed drug combination, but their delivery is challenged by suboptimal solubility and physical instability. This study explores the potential of active pharmaceutical ingredient-ionic liquids (API-ILs) to improve the physicochemical and pharmaceutical properties of INH and RIF. Antitubercular drugs, INH, or RIF, were paired with different counter ions (ascorbic acid (AsA), citric acid (CA), tartaric acid (TA), benzoic acid (BA), salicylic acid (SA), and p-amino salicylic acid (PAS)) using the solvent evaporation method. INH and RIF API-ILs were formed successfully using AsA and CA counter ions. IL formation was examined and analyzed using Fourier transform infrared (FTIR) spectroscopy, x-ray powder diffraction (XRPD), and polarized optical microscopy (POM). XRPD and POM confirmed their amorphous nature, while FTIR analysis demonstrated the contribution of hydrogen bonding to IL formation. IL formation enhanced the storage stability of the INH + RIF mixture in the presence of CA. Moreover, RIF-CA IL significantly increased the rate and extent of RIF dissolution. An effect that is unattainable with the RIF/CA physical mixture. Thus, API-IL formation not only enhances RIF dissolution but also facilitates the preparation of stable, compatible INH-RIF combinations. Graphical Abstract
A Green UPLC Method for the Simultaneous determination of Tenofovir and Amoxicillin in Biological Fluids and Dosage Forms
This paper elucidates the process of developing and validating the UPLC technique, aiming to enable the concurrent measurement of tenofovir and amoxicillin. This UPLC method is accurate and sensitive. The experimental setup involved utilizing a Kinetex 1.7μ C18 100A (2.1-mm × 50-mm) column maintained at a temperature of 30°C. The mobile phase employed a combination of methanol and phosphate buffer (0.1% orthophosphoric acid in water, pH 3.5) in a ratio of 30:70 (v/v). The flow rate was set at 0.2mL/min, and the detection wavelength for analysis was 230nm. All these conditions resulted in optimum chromatographic separation. This developed method of UPLC took less than 4 minutes to separate this mixture. The detection limits for two medications were determined to be 0.45µg/mL for tenofovir and 0.26µg/mL for amoxicillin. The calibration plots of both substances exhibited satisfactory linearity within the concentration range of 1.0 - 2.0 µg/mL. Remarkably, the method demonstrated excellent performance with high percentage recoveries ranging from 96.8% to 102.92% and low percentage relative standard deviation (%RSD) values below 2%. Consequently, the proposed methodology proved to be highly effective for detecting the targeted drugs in their respective dosage forms.
Effect of Gamma Irradiation on Cannabinoid, Terpene, and Moisture Content of Cannabis Biomass
In recent years, cannabis has been proposed and promoted not only as a medicine for the treatment of a variety of illnesses, but also as an industrial crop for different purposes. Being an agricultural product, cannabis inflorescences may be contaminated by environmental pathogens at high concentrations, which might cause health problems if not controlled. Therefore, limits have to be placed on the levels of aerobic bacteria as well as yeast and mold. To ensure the safety of cannabis plant material and related products, a remediation process has to be put in place. Gamma irradiation is a sterilization process mainly used for pharmaceuticals, foods, cosmetics, agricultural, and herbal products including cannabis plant material. This study was designed to determine the effect of irradiation on the microbial count as well as on the chemical and physical profiles of the cannabis biomass, particularly cannabinoids, terpenes, and moisture content. The full cannabinoid profile was measured by GC/FID and HPLC analysis, while terpene profile and moisture content were determined using GC/MS and Loss on Drying (LoD) methods, respectively. Analyses were conducted on the samples before and after gamma irradiation. The results showed that the minimum and maximum doses were 15 and 20.8 KiloGray (KGY), respectively. Total Aerobic Microbial Count (TAMC) and Total Yeast and Mold Count (TYMC) were determined. The study showed that irradiation has no effect on the cannabinoids and little effect on terpenes and moisture content, but it did result in the virtual sterilization of the plant material, as evidenced by the low levels of bacterial and fungal colony-forming units (CFUs) < 10 after gamma irradiation.
The potential of microneedle platforms in addressing pediatric drug delivery challenges: perspectives of healthcare professionals and parents
Background Pediatric drug delivery faces significant challenges owing to children’s unique physiology and limitations of conventional dosage forms. There is a growing need for age-appropriate, safe, and effective alternatives. Objectives This study aimed to assess the challenges in selecting pediatric pharmaceutical dosage forms and to evaluate the potential of microneedles (MNs) as an innovative solution, capturing perspectives of healthcare professionals (HCPs) and parents. Methods Two cross-sectional surveys were conducted: (1) a survey for pediatricians ( n  = 154) on dosage form challenges, and (2) a survey of HCPs and parents ( n  = 386) on perceptions of MNs for pediatric drug delivery. Responses were analyzed quantitatively and qualitatively. Results Pediatricians identified key barriers: unsuitable formulations (53%), injection distress (38%), and inadequate strength availability (29%). Cost (59%), therapeutic efficacy (60%), and administration route (53%) dominated prescribing decisions. Anti-infectives (69%) and analgesics (47%) were top candidates for reformulation. Respondents (85%) acknowledged needle phobia as a major issue, and 84% expressed willingness to use MNs, peaking at 93% for children aged 1–3 years. MNs’ perceived advantages included reduced needle phobia, improved compliance in chronic diseases, and self-administration potential. Primary concerns included practicality in emergencies (59%), drug-loading capacity (46%), and dosing accuracy. Conclusions Significant unmet needs persist in pediatric drug delivery. MNs demonstrate strong potential to address core challenges, particularly needle aversion and formulation unsuitability, with high acceptance among stakeholders. Translation requires overcoming barriers in manufacturing scalability, regulatory clarity, and user-centered design. Coordinated efforts in education, targeted formulation development, and policy advocacy are essential for clinical integration.
GC-MS/MS Quantification of EGFR Inhibitors, β-Sitosterol, Betulinic Acid, (+) Eriodictyol, (+) Epipinoresinol, and Secoisolariciresinol, in Crude Extract and Ethyl Acetate Fraction of Thonningia sanguinea
Medicinal plants are widely used in folk medicine to treat various diseases. Thonningia sanguinea Vahl is widespread in African traditional medicine, and exhibits antioxidant, antibacterial, antiviral, and anticancer activities. T. sanguinea is a source of phytomedicinal agents that have previously been isolated and structurally elucidated. Herein, gas chromatography combined with tandem mass spectrometry (GC-MS/MS) was used to quantify epipinoresinol, β-sitosterol, eriodictyol, betulinic acid, and secoisolariciresinol contents in the methanolic crude extract and its ethyl acetate fraction for the first time. The ethyl acetate fraction was rich in epipinoresinol, eriodictyol, and secoisolariciresinol at concentrations of 2.3, 3.9, and 2.4 mg/g of dry extract, respectively. The binding interactions of these compounds with the epidermal growth factor receptor (EGFR) were computed using a molecular docking study. The results revealed that the highest binding affinities for the EGFR signaling pathway were attributed to eriodictyol and secoisolariciresinol, with good binding energies of −19.93 and −16.63 Kcal/mol, respectively. These compounds formed good interactions with the key amino acid Met 769 as the co-crystallized ligand. So, the ethyl acetate fraction of T. sanguinea is a promising adjuvant therapy in cancer treatments.

Anti-inflammatory and antioxidant effect of Moringa oleifera against bisphenol-A-induced hepatotoxicity
Non-pharmacological exposure or pharmacological drug-induced hepatic injury is the most common cause of hepatotoxicity. This study was conducted to evaluate the effect of Moringa oleifera leaf extract against bisphenol-A (BPA)-induced hepatic toxicity in rats. Rats (n=56) were randomized into 7 groups (8 rats/each). Control groups: rats received olive oil or Moringa oleifera (400mg/kg) orally for 42 days. Hepatotoxicity groups: rats received BPA (50mg/kg BW) orally in a 1-ml olive oil for 42 days. Reversal groups: rats received Moringa oleifera (200 or 400mg/kg) and BPA (50mg/kg BW) for 42 days. Preventive groups: rats received Moringa oleifera (200 or 400mg/kg) for 30 days followed by BPA (50mg/kg BW) for 14 days. At the end of the experiments, blood samples were collected for glucose and liver function assay, while the liver tissue samples were collected and homogenated for measuring the inflammatory/oxidant and antioxidant markers. Rats with BPA-induced hepatotoxicity have significantly increased serum aspartate transaminase (AST), alanine transaminase (ALT), and glucose; liver lysate malondialdehyde (MDA); tumor necrosis factor (TNF-[alpha]); and macrophage migrating inhibitory factor (MIF) but significantly decreased levels of liver lysate reduced glutathione (GSH) and total antioxidant capacity (TAC) levels. The administration of Moringa oleifera (especially 400mg/kg BW) in both reversal and preventive groups ameliorate the toxic effects of BPA in rats, as it decreased the activities of AST, ALT, glucose, MDA, TNF-[alpha], and MIF levels and increased the antioxidant levels of GSH and TAC. Moringa oleifera has hepatoprotective effects against BPA-induced liver damage through the regulation of antioxidants and inflammatory biomarkers.
Molecular docking and statistical optimization of taurocholate-stabilized galactose anchored bilosomes for the enhancement of sofosbuvir absorption and hepatic relative targeting efficiency
The work aimed to improve both absorption and hepatic availability of sofosbuvir. Bilosomes and galactose-anchored bilosomes were investigated as potential nanocarriers for this purpose. Sofosbuvir is a class III drug with high solubility and low permeability. Thus, the drug entrapment into lipid-based galactose-anchored carriers would enhance drug permeability and improve its liver availability. The galactosylated taurocholate was designed and synthesized based on molecular docking studies, where both galactose and taurocholate molecules were connected in a way to avoid affecting crucial interactions and avoid steric clashes with their cellular uptake receptors. The suggested nano-carriers were prepared using a thin-film hydration technique with sodium taurocholate and span 60 as stabilizers. The prepared formulae were statistically optimized using a central composite design. The optimized plain and galactosylated formulae, composed of SAA to drug ratio of 1:1 w/w and sodium taurocholate to span ratio of 10:1 w/w, have a vesicular size, zeta potential and entrapment efficiency in the range of 140-150 nm, −50 mV and 85%, respectively. The optimized formulae were lyophilized to increase their physical stability and facilitate accurate drug dosing. In vivo results showed that Sofosbuvir availability in the liver was significantly increased after oral administration of the plain and the galactosylated bilosomal formulae when compared to the oral drug solution with relative targeting efficiencies (RTIs) of 1.51 and 3.66, respectively. These findings confirmed the hypothesis of considering the galactosylated bilosomes a promising nanocarrier to efficiently target sofosbuvir to the liver.
