This paper presents software for calculating the optimal mass of samples with complex compositions (e.g. supported metal catalysts) for X-ray absorption spectroscopy (XAS) and scattering measurements. The ability to calculate the sample mass and other relevant parameters needed for an XAS measurement allows experimentalists to be better prepared in terms of detector selection, energy range of scan and overall time needed to complete the measurement, thus increasing efficiency. CatMass builds on existing sample mass calculators allowing users to determine the optimum sample preparation, collection geometry, usable energy range for a scan and approximate edge step of the absorption event. Visualization tools present the absorption calculation results in a format familiar to XAS experimentalists, with the added ability to save calculations and plots for future reference or recalculation. CatMass is a program broadly applicable in catalysis and is helpful for users with complex samples due to composition/stoichiometry or multiple competing elements.

Purpose: We developed software that can analyze central lung distance (CLD) and central skin distance (CSD) in deep inspiration breath hold (DIBH) irradiation and verified the reproducibility of the DIBH irradiation method in our hospital.
Methods: CLD and CSD were analyzed using In-house software using cine images acquired during treatment; intra- or inter-fractional motion was calculated from the obtained data and compared with other reports using systematic error (ΔΣ) and random error (Δσ).
Results: The ΔΣ and Δσ were 1.
Comparison of Vertical Marginal Discrepancy in High and Low Translucent Monolithic Zirconia Crowns in Repeated Firing Cycles.

Dental Materials Research Center, Department of Prosthodontics, School of Dentistry, Isfahan University of Medical Sciences, Isfahan, Iran.
Objective: Increase in vertical marginal discrepancy (VMD) during repeated firing cycles and its clinical outcomes is a major concern for high and low translucent monolithic zirconia crowns. The purpose of this in vitro study was to evaluate and compare VMD in high and low translucent monolithic zirconia crowns in repeated firing cycles.
Material And Methods: To perform this study, 10 monolithic zirconia crowns made by computer-aided design and computer-aided manufacturing method were used in two groups of five with high and low translucency, which were designed on Zimmer tissue-level implant abutment.
Buprenorphine-naloxone versus buprenorphine for opioid use disorder during pregnancy: A systematic review and meta-analysis.

Institute of Psychiatry and Neurology, Child and Adolescent Psychiatry Clinic, Warsaw, Poland. Electronic address:
Background: The standard of care for treating opioid use disorder (OUD) during pregnancy includes either buprenorphine or methadone. Although buprenorphine-naloxone presents an alternative due to the reduced risk of misuse , evidence regarding its impact on pregnancy and infant health remains limited. This systematic review and meta-analysis aims to compare buprenorphine-naloxone vs buprenorphine alone for OUD during pregnancy, assessing gestational and neonatal outcomes.

The phenomenological and microscopic level density models were utilized within the TALYS 2.0 software to simulate the cross-sections of proton-induced reactions on both natural and enriched copper. This process resulted in the production of the zinc radioisotopes Zn, Zn, and Zn, which hold significance in diagnostic and therapeutic medicine.
