Perioperative escape from dormancy of spontaneous micro-metastases: A role for malignant secretion of IL-6, IL-8, and VEGF, through adrenergic and prostaglandin signaling
Brain Behav Immun. 2023 Jan 13:S0889-1591(23)00005-3. doi: 10.1016/j.bbi.2023.01.005. Online ahead of print.ABSTRACTWe recently showed that a minimally-invasive removal of MDA-MB-231HM primary tumors (PTs) and elimination of their secreted factors (including IL-6, IL-8, VEGF, EGF, PDGF-aa, MIF, SerpinE1, and M-CSF), caused regression of spontaneous micro-metastases into a non-growing dormant state. To explore the underlying mechanisms and potential clinical ramifications of this phenomenon, we herein used the MDA-MB-231HM human breast cancer cell-line, in-vitro, and in vivo following orthotopic implantation in immune-defic...

Molecules, Vol. 28, Pages 235: Nanostructured Lipid Carriers (NLC)-Based Gel Formulations as Etodolac Delivery: From Gel Preparation to Permeation Study
In this study, an NSAID from the BCS class II, etodolac (ETD), was used. The nanostructured lipid carriers (NLC) obtained with ETD were incorporated into semi-solid forms (gels). Hydrogels with the suspended drug and oleogel were also prepared for comparison purposes. The obtained gels were tested in terms of pH, viscosity, rheological, mechanical, and bioadhesive properties. The release and permeation through membranes were also studied. All tested formulations were characterized by a pH below 7, which ensured the physiological state of the skin. The viscosities of all gels decreased with increasing shear rate, indicating...

Case Reports of Transdermal Fentanyl Patch Administration Difficulties in Cancer Patients with Excess Sweating
J Pain Palliat Care Pharmacother. 2022 Nov 15:1-6. doi: 10.1080/15360288.2022.2141413. Online ahead of print.ABSTRACT(Case 1) A 45-year-old male was diagnosed with prostate cancer. Treatment was administered using bicalutamide and leuprorelin acetate, while a transdermal fentanyl (TDF) was applied for pain relief. However, TDF continued to peel off owing to excessive sweating, even when reinforced by a protective layer. As such, TDF was discontinued and pain control was initiated using other medicines. Sweating occurred irregularly because of hot flashes, approximately four to five times per day. (Case 2) A 37-year-old mal...

Species differences in liver microsomal hydrolysis of acyl glucuronide in humans and rats
This study was aimed to clarify species differences in AG hydrolysis between human and rat liver microsomes (HLM and RLM).To evaluate the AG hydrolysis profile, and the contribution of β-glucuronidase and esterase towards AG hydrolysis in HLM and RLM, nonsteroidal anti-inflammatory drugs (NSAIDs) were used. AGs were incubated with 0.1 M Tris-HCl buffer (pH 7.4) and 0.3 mg/mL HLM or RLM in the absence or presence of β-glucuronidase inhibitor, D-saccharic acid 1,4-lactone (D-SL) and esterase inhibitor, phenylmethylsulfonyl fluoride (PMSF).AGs of zomepirac (ZOM-AG), mefenamic acid (MEF-AG), and etodolac (ETO-AG) showed sign...

Application of ionic liquid to enhance the nose-to-brain delivery of etodolac
Eur J Pharm Sci. 2022 Sep 1:106290. doi: 10.1016/j.ejps.2022.106290. Online ahead of print.ABSTRACTThe purpose of this study was to enhance the delivery of Etodolac (ETD) to the brain through intranasal administration using an ionic liquid (IL) consisting of ETD and proline ethyl ester. The IL of ETD was prepared by mixing ETD with proline ethyl ester as a counterion in a molar ratio of 1:2.The formation of the IL was confirmed by differential scanning calorimetry (DSC), infrared spectroscopy (IR) and proton nuclear magnetic resonance (1H-NMR).The solubility of ETD in simulated nasal fluids was improved by approximately 20...

In recent years, HO° and SO4°- based advanced oxidation processes (AOPs) have been widely applied in water and wastewater treatments due to their highly efficiency on contaminant removal.
