Methods: Using Box-Behnken Design (BBD) three independent variables (Soya lecithin, polysorbate content, and homogenization speed) and four dependent variables (% entrapment efficiency (EE), % drug release (DR), zeta potential (ZP), and particle size (PS)) were chosen for the study. The formulations were prepared by the hot homogenization method and characterized with SEM, FTIR, DSC, and XRD and evaluated their % EE, % DR, PS, and ZP. Developed SLNs were tested for their hepatoprotective activity by an in vivo mice model and compared the effectiveness with free NAC and Silymarin. Results: The optimized NAC-SLNs were found optimum with spherical and intact chemical structure (88.95% EE, 97.15% DR, -43.01 mv ZP, < 200 nm of PS) exhibiting Higuchi model of drug release. In terms of MDA levels, NAC-SLNs had a strong protective impact MDA level (23.09±0.01–21.84±0.01 u mole/mg protein) and were efficient in increasing GPx (16.89±0.01–20.71±0.02 unit/mg protein), GSH (18.94±0.57–24.21±1.00 unit/mg protein), which were reduced in the CCl4-intoxicated group.

Alginate can be combined with a suitable polymer and cross-linked with divalent ions and another polymer to enhance the solubility of the drug. Ketoconazole could be loaded into a matrix polymer consisting of alginate and anionic polymer through hydrogen bonds formed with the N atom of the ketoconazole. The method employed to produce ketoconazole beads involved ionic gelation with CaCl2 as a cross- linking agent, and various polymer combinations were used: alginate 100:0 (AL100), alginate:pectin 75:25 (AP75) and 50:50 (AP50), alginate:gum acacia 75:25 (AG75) and 50:50 (AG50), and alginate:carrageenan 75:25 (AK75) and 50:50 (AK50). The beads were characterized by using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), swelling study, in vitro drug release study, and solubility determination.

Serum samples from patients with Alzheimer’s disease (AD), frontotemporal dementia (FTD), dementia of unknown etiology (DUE), and healthy controls were probed using a set of 130 7-mer peptides relevant to neurodegenerative diseases. Results show that linear peptides probed with IgM yielded higher graph density compared to IgG, indicating different levels of polyspecificities.

Ketogenic diets (KD), which are high in fat, low in carbohydrates, and sufficient in protein, can be used alone or as adjuvants with cancer drug medication as cancer therapy or prevention methods. Probiotics are nonpathogenic microorganisms or groups of bacteria that live in the gut and nourish the host body. In this work, we tested a new KD-probiotic combination against breast cancer implanted in mice. Several combination of probiotics (1×109 CFU/0.5ml) and KD (14.1 kcal/2g) reduced tumor size and enhanced cure rate. KD and combination therapy groups increased beta-hydroxybutyrate (β-OHB) while decrease blood glucose, and IGF-1.IFN-γ, IL-2, IL-4, and IL-10 serum levels were measured to assess immune reaction to various therapies. Combination and probiotics therapy raised IFN-γ, and IL-4 levels, however IL-10 level did decrease in all treated group with highest decrease in combination group. In the safety profile, probiotics, ketogenic diet, and their combination were safe.

Methods. All patients with Ph+, BCR-ABL1+ CML who were treated and observed between 01.01.2018 and 12.31.2022 at the clinic were included in the study and were analyzed retrospectively. Results. One hundred and eighty-eight patients with a mean age of 61.26 (21–91) years were analyzed. 151 (80.3%) were in chronic phase (CP), 27 (14.4%) in accelerating one and 10 (5.3%) in blast crisis.

Diacerein is a disease-modifying agent indicated for osteoarthritis management with enhanced performance and have much lower side effects profile than conventional non-steroidal anti-inflammatory drugs. Oral administration of Diacerein is associated with a laxative effect , thus causing treatment discontinuation. Aim: This study aimed to evaluate the activity of Diacerein novasome-based transdermal gel compared with standard oral treatment in the management of induced osteoarthritis in a rat model. Materials and methods: A single intra-articular injection of monosodium iodoacetate was administered to the left knee joint, resulting in the development of Osteoarthritis. Disease progression and the effect of both routes of Diacerein treatment were evaluated by morphological, biochemical, histological, and radiological studies. Results: Osteoarthritis was successfully induced in rats’ knee joints. Morphological studies revealed that both Diacerein treatments significantly reduced joint swelling as compared to the untreated group. The serum TNF-α and IL-1β levels were significantly lower in both Diacerein treatment groups as compared to the untreated group throughout the course of the study. Histological and radiological findings confirmed that transdermal Diacerein treatment protects against cartilage degradation like oral treatment. Conclusion: Novasomal technology proved its efficacy as a carrier for the transdermal delivery of Diacerein. The in-vivo study on an animal model of osteoarthritis showed that Diacerein transdermal gels provided sufficient pharmacological activity for the attenuation of the disease. This finding could support its use as an alternative to the standard oral treatment to avoid side effects.","PeriodicalId":20086,"journal":{"name":"Pharmacia","volume":"56 2 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139253613","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}
