Aim: The aim of this study was to compare the wear resistance of cast gold with condensable bulk fill and a fiber reinforced bulk-fill composite.
Materials And Methods: The 5 mm × 4 mm stainless steel molds were prepared for wear resistance. Forty-five samples were divided into three groups (n = 15). The samples were restored as follows: Group I: cast gold alloy (d. SIGN 98; Ivoclar Vivadent), Group II: fiber reinforced composite (Ever X Posterio; r GC Corp.), and Group III: condensable bulk-fill composite (Tetric N Ceram; Ivoclar Vivadent). A pin on disc wear tester was used to measure the wear resistance. Data were analyzed using one-way analysis of variance.
Results: Higher statistically significant values were seen for the cast gold restorations than the other two bulk-fill composites.
Conclusion: It is desirable for any restorative material to yield wear behavior. D. SIGN 98 (Type IV cast gold alloy) was the most wear resistant material tested, whereas Tetric N Ceram (condensable bulk-fill composite) was the least wear resistant.

Background: There is inconsistent evidence as to the role of testosterone and pre-androgens in premenopausal female sexual function, and reported associations between blood concentrations of these hormones and female sexual function vary in strength.
Aim: To examine the patterns of testosterone and pre-androgen concentrations and variations in sexual function in premenopausal eumenorrheic women.
Methods: This was a secondary analysis of a sample of 588 premenopausal eumenorrheic women from the Grollo-Ruzzene Foundation Young Women's Health Study.
Applications of basophil activation test in paediatric allergic diseases.

Basophilic granulocytes, containing and releasing histamine after a specific allergy stimulation, are directly involved in IgE-mediated allergic reactions. CD63 is a transmembrane protein of secretory lysosomes of basophils and its upregulation is related with the release of histamine to the extracellular space during IgE-mediated allergic reactions. Basophil activation test (BAT) measures the activation of circulating basophils upon the stimulation of living blood cells with specific allergens.

Article Synopsis
- Researchers have created decanuclear chiral gold(I) sulfido clusters (S-Au and R-Au) using specialized SDP ligands.
- Mixing these chiral clusters in a 1:1 ratio yields an achiral heterodimer icosanuclear meso-cluster (meso-Au), which exhibits intense near-infrared luminescence with a peak at around 750 nm.
- The study highlights the significant increase in photoluminescence quantum yield for meso-Au (25%) compared to the chiral clusters (8%), and shows that the clustering process is influenced by solvent polarity and diphosphine ligand configuration, aiding the understanding of self-sorting in chiral assemblies.
