Squalene synthase (SQS) plays a crucial role in the cholesterol biosynthetic pathway. Its distinctive strategic position makes it a promising candidate for targeting and developing new anti-hypercholesterolemic agents. To uncover novel phytochemical scaffolds as potential inhibitors of SQS, we employed a structure-based virtual screening approach that involves screening 545 phytochemicals collected from Moroccan aromatic and medicinal plants and filtering them based on RMSD values and their affinity towards the target enzyme.

Rovisco Pais, 1049-001 Lisbon, Portugal; Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Caparica, Almada, Portugal. Electronic address:

When placed in the eye, contact lenses (CLs) disturb the tear fluid and affect the natural tribological behaviour of the eye. The disruption in the contact mechanics between the ocular tissues can increase frictional shear stress and ocular dryness, causing discomfort. Ultimately, continuous CLs wear can trigger inflammation which is particularly critical for people suffering from dry eye.

This study investigates the integration of Broadband Cavity Enhanced Absorption Spectroscopy (BBCEAS) with High-Performance Liquid Chromatography (HPLC) to detect synthetic antioxidants; BHA, BHT, and TBHQ in the deep-UV region below 300 nm. The research addresses the need for more sensitive and cost-effective detection methods in HPLC systems, particularly for low analyte concentrations, by exploring BBCEAS as a superior alternative to conventional detectors that often fall short in sensitivity. The sensitivity of the HPLC-BBCEAS system is assessed by calculating the minimum detectable change in the absorption coefficient (αmin) and comparing with those obtained using conventional HPLC and single-wavelength HPLC-CRDS methods.

Article Synopsis
  • Co-amorphous systems (CAMs) can improve the solubility of poorly water-soluble drugs, but challenges like a limited number of co-formers and lab-scale preparation techniques exist.
  • This study uses aspartame and dipyridamole to create CAMs through spray drying, showing that AspPhe has better solid-state properties and physical stability than individual amino acids.
  • Molecular interactions analyzed by Hirshfeld Surface analysis and FT-IR spectroscopy demonstrate that hydrogen bond interactions significantly enhance the stability of the DPM-AspPhe co-amorphous system, while crystallization rates are affected by temperature and humidity.

Antimicrobial resistance (AMR) poses a critical threat to global public health, necessitating the development of novel strategies. AMR occurs when bacteria, viruses, fungi, and parasites evolve to resist antimicrobial drugs, making infections difficult to treat and increasing the risk of disease spread, severe illness, and death. Over 70% of infection-causing microorganisms are estimated to be resistant to one or several antimicrobial drugs.

Poultry manure is widely used as organic fertilizer in agriculture during the cultivation of crops, but the persistent high-level use of antibiotics in poultry production has raised concerns about the selection for reservoirs of antimicrobial resistance genes (ARGs). Previous studies have shown that the addition of poultry manure can increase the abundance of genes associated with resistance to tetracyclines, aminoglycosides, fluoroquinolones, sulfonamides, bacitracin, chloramphenicol, and macrolide-lincosamide-streptogramin in soil and plants. Understanding the microbial populations that harbor these ARGs is important to identify microorganisms that could enter the human food chain.

Article Synopsis
  • The study emphasizes the significance of understanding how farm locations and sizes affect disease spread, especially as livestock production intensifies in certain regions, making accurate spatial data crucial for effective interventions.
  • Researchers created a Farm Distribution Model (FDM) that predicts poultry farm locations and sizes in data-scarce countries using advanced modeling techniques, including a Log-Gaussian Cox process and random forest model.
  • The FDM provides realistic farm distributions and highlights that spatial clustering increases epidemic vulnerability, demonstrating the model's importance in predicting disease spread in areas without extensive data.

Background: Adenomyosis can lead to infertility and failure of in vitro fertilization. Limited evidence suggests that the use of long-term treatment with gonadotropin-releasing hormone (GnRH) agonists followed by frozen-thawed embryo transfer (FET) may be the preferred approach for women with adenomyosis.

Objective: The aim of this randomized controlled trial is to compare the efficacy of an ultra-long GnRH agonist with standard downregulation in women with adenomyosis undergoing FET.

Benign hyperplasia (BHP) is a common disorder that affects men over the age of 60 years. Transurethral resection of the prostate (TURP) is the gold standard for operative treatment, but a range of drugs are also available to improve quality of life and to reduce BHP-associated urinary tract infections and complications. Darifenacin, an anti-muscarinic agent, has been found effective for relieving symptoms of overactive bladder associated with BHP, but the drug has poor solubility and bioavailability, which are major challenges in product development.
