Low aqueous solubility and bioavailability is the limiting factor to achieve desired therapeutic efficacy for variety of new and existing drug moieties. The goal of the present study was to explore the effects of β-cyclodextrin (βCD) and hydroxypropyl-β-cyclodextrin (HPβCD) on the solubility and dissolution profile of diflunisal (DIF) prepared by using two different methods (physical mixing and solvent evaporation) at DIF-cyclodextrins weight ratios of 1:1, 1:2 and 1:4. The phase solubility studies demonstrated that DIF solubility increased proportionally with an increase in βCD and HPβCD concentration. The inclusion complexes were subjected to characterization of scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and X-ray diffractometry (XRD). Solvent evaporation yielded higher DIF solubility than physical mixing method. HPβCD-DIF inclusion complexes yielded higher dissolution profile than βCD complexes when prepared under same experimental design. FTIR, DSC and XRD confirmed the successful inclusion of DIF into cyclodextrin (βCD/HPβCD) by both preparation methods with enhanced water solubility and drug release in comparison with pure drug.

The complexity of allosteric enzymatic regulation continues to inspire synthetic chemists seeking to emulate interconnected biological systems. In this work, a Pt2L4 cage capable of catalyzing the cyclization reaction of an alkynoic tosyl amide is orthogonally coupled to a diacid-catalyzed carbodiimide-hydration cycle. This new Pt-catalyzed cyclization reaction is demonstrated to exhibit electronic regulation by inclusion of different guest effectors.

Background Maternal diabetes mellitus (DM) is a known risk factor for congenital heart diseases (CHDs), which are of significant concern to infants born to diabetic mothers. Compared to newborns born to non-diabetic mothers, infants born to diabetic mothers had a higher overall risk of developing congenital malformations. This association has a complex pathophysiology that includes genetic predispositions, metabolic abnormalities, and environmental factors during key stages of fetal development.

Introduction: The fact that inclusive education has existed in Bosnia and Herzegovina for twenty years opens the question of how it affects typically developing children, among other things. This paper aims to examine the differences in general knowledge and mathematics of typically developing students with regard to whether they attend classes that include students with intellectual disabilities or not, as well as to determine the relationship of their knowledge with teachers' characteristics and the inclusiveness of schools they attend.
Methods: The sample included 331 students from 18 regular elementary school classes.
Understanding Self-Criticism: A Systematic Review of Qualitative Approaches.
Clin Neuropsychiatry
December 2024
School of Cognitive Psychotherapy, Rome, Italy.
Objective: Self-criticism (SC) is a central transdiagnostic factor in several psychopathological conditions, influencing the development and maintenance of symptomatology. The importance of this construct has stimulated quantitative and qualitative research about it. The main purpose of this systematic review is to highlight which qualitative methods have been used most frequently and which are most suitable for studying SC.
