Article Synopsis
  • The WHO recognized the mpox outbreak as a global health emergency, highlighting the importance of involving healthcare providers like pharmacists in prevention efforts.
  • A survey conducted in the UAE assessed the knowledge and preparedness of pharmacy students and pharmacists regarding mpox, revealing that many rely on WHO reports for information.
  • The findings showed that while awareness exists, confidence in diagnosing and managing mpox is low, with only about 31% feeling capable in diagnosis and 34.6% in management, and many fear mpox could be the next major health crisis.

Article Synopsis
  • - Bacteria can hide inside host cells like macrophages to evade antibiotics, prompting research on using PLGA nanoparticles to deliver antibiotics to these intracellular bacteria.
  • - Different sizes of Rhodamine-B conjugated PLGA nanoparticles were tested to see how well they were taken up by macrophages and epithelials, showing larger nanoparticles had better uptake by macrophages.
  • - In tests against intracellular infections, larger antibiotic-loaded PLGA nanoparticles were more effective against K. pneumoniae, but not against S. aureus, suggesting that there's no universal solution for targeting all types of intracellular infections.

Racecadotril, an anti-secretory medication, has been used as an adjuvant in an oral rehydration therapy for children experiencing severe diarrhea. Racecadotril is quickly converted to thiorphan, an active metabolite, after oral treatment, which mediates all subsequent activities. An efficient and rapid liquid chromatography-tandem mass spectrometry method was developed and fully validated to measure thiorphan in human plasma, using thiorphan-d7 as an internal standard.

Encapsulation of gingerol into nanoliposomes: Evaluation of in vitro anti-inflammatory and anti-cancer activity.

Biomed Chromatogr

August 2024

University of Petra Pharmaceutical Center (UPPC), Faculty of Pharmacy and Medical Sciences, University of Petra, Amman, Jordan.

Nanoliposomes (NLs) are ideal carriers for delivering complex molecules and phytochemical products, but ginger by-products, despite their therapeutic benefits, have poor bioavailability due to their low water solubility and stability. Crude ginger extracts (CGEs) and 6-gingerol were individually encapsulated within NLs for in vitro activity assessment. In vitro evaluation of anti-proliferative and anti-inflammatory properties of encapsulated 6-gingerol and CGE was performed on healthy human periodontal ligament (PDL) fibroblasts and MDA-MB-231 breast cancer cells.

Inhibitors of the p53-MDM2 interaction such as RG7388 have been developed to exploit latent tumor suppressive properties in p53 in 50% of tumors in which p53 is wild-type. However, these agents for the most part activate cell cycle arrest rather than death, and high doses in patients elicit on-target dose-limiting neutropenia. Recent work from our group indicates that combination of p53-MDM2 inhibitors with the class-I HDAC inhibitor Entinostat (which itself has dose-limiting toxicity issues) has the potential to significantly augment cell death in p53 wild-type colorectal cancer cells.

The primary objective of this study was to enhance the effectiveness of the protease inhibitor antiretroviral drug by designing a novel delivery system using carboxylated multiwalled carbon nanotubes (COOH-MWCNTs). To achieve this, Fosamprenavir calcium (FPV), a prodrug of amprenavir known for inhibiting the proteolytic cleavage of immature virions, was selected as the protease inhibitor antiretroviral drug, and loaded onto COOH-MWCNTs using a direct loading method. The structural specificity of the drug-loaded MWCNTs, the percent entrapment efficiency, and in vitro drug release were rigorously evaluated for the developed formulation, referred to as FPV-MWCNT.

Synergistic combination of doxorubicin with hydralazine, and disulfiram against MCF-7 breast cancer cell line.

PLoS One

September 2023

Department of Nanoscience, Joint School of Nanoscience and Nanoengineering, University of North Carolina at Greensboro, Greensboro, NC, United States of America.

Disulfiram and hydralazine have recently been reported to have anti-cancer action, and repositioned to be used as adjuvant in cancer therapy. Chemotherapy combined with other medications, such as those that affect the immune system or epigenetic cell profile, can overcome resistance with fewer adverse effects compared to chemotherapy alone. In the present study, a combination of doxorubicin (DOX) with hydrazine (Hyd) and disulfiram (Dis), as a triple treatment, was evaluated against wild-type and DOX-resistant MCF-7 breast cancer cell line.

Ulcerative colitis (UC) and Crohn's disease (CD) are two types of idiopathic inflammatory bowel disease (IBD) that are increasing in frequency and incidence worldwide, particularly in highly industrialized countries. Conventional tablets struggle to effectively deliver anti-inflammatory drugs since the inflammation is localized in different areas of the colon in each patient. The goal of 3D printing technology in pharmaceutics is to create personalized drug delivery systems (DDS) that are tailored to each individual's specific needs.
