Melt quenching technique was used to create Bismuth Boro-Silicate nano glasses with compositions of 45SiO 2 -10CaO- 25Na 2 O- xBi 2 O 3 - (20-x) B 2 O 3 (where x is 0, 5, 10, 15, and 20 mol %). Standard point sources AM-241, Ba-133, Co-60, Cs-137, and Eu-152 were used in the radiation experiment to evaluate the attenuation coefficients spanning the energy range of 59.51 keV to 1048.01 keV. The findings show that adding Bi 2 O 3 in place of B 2 O 3 increases the following: radiation protection efficiency (RPE%), transmission factor (TF%), absorption buildup factor values (ABF), exposure buildup factor values (EBF), mass attenuation coefficients (MACs), linear attenuation coefficients (LACs), and radiation protection efficiency (RPE%). In comparison to lead glass, these findings demonstrate the potential of nano Bismuth Boro-Silicate glass as a radiation shielding material., (© 2024. The Author(s).)

In the present study, a novel glass system containing Neodymium(III) oxide with BaO, Al 2 O 3 , and B 2 O 3 were created via a popular melt-quenching technique. Nd 2 O 3 were added, in different concentrations, instead of B 2 O 3 to study its impact on the crystallization, and electro-magnetic behaviors of the prepared poly-crystalline materials. Thermal characteristics via DTA, XRD and SEM techniques were involved to explore the crystallization and structural properties. The magnetic parameters of the prepared glass-ceramics were studied by VSM measurements. As well the electric properties were also explored. BaB 2 O 4 and Al(BO 3 ) phases were firstly crystallized then Ba 3 Nd(BO 3 ) 3 phase was incompletely precipitated instead of BaB 2 O 4 phase owing to Nd 2 O 3 additions. As well, the internal structure was modified from coarse crystals to fine grain microstructure. The crystallization study proved that the addition of neodymium improved the crystallization process of the BaO-Al 2 O 3 -B 2 O 3 glass system. The VSM and conductivity analysis for the crystalline materials proved that the Nd 2 O 3 /B 2 O 3 substitutions led to an increase in the electrical and magnetic parameters of the investigated materials. The data obtained from the prepared crystalline specimen showed that these materials are with a distinct and promising ferro-electrical property for use in diverse modern applications., (© 2023.

In order to investigate the significance of p53 deletion, 42 specimens of transitional cell carcinoma were analyzed by interphase cytogenetics with a fluorescence in situ hybridization technique and compared with clinicopathological and cytochemical parameters. In total, 27 (64%) and 16 (38%) specimens demonstrated p53 deletion and overexpression, respectively. The p53 deletion was significantly correlated with grade (P < 0.01), stage (P < 0.05), S-phase fraction (P < 0.05), and DNA ploidy (P < 0.01), while p53 overexpression correlated only with grade (P < 0.05). The close correlation of p53 deletion with clinicopathological parameters suggests p53 deletion to be of clinical importance to indicate the malignant potential of human urothelial tumors.
