Synthesized 3,4-Diaminothieno[2,3-b]thiophene-2,5-dicarbohydrazide (DTT) Schiff base derivatives newly were synthesized by attaching with different aldehydes, deposited in thin film form by thermal evaporation technique, and characterized by UV-Visible-NIR spectroscopy, FT-IR, NMR, and elemental analysis. It is revealed that compound 4 has the highest absorption peak intensity at 586 nm. The allied absorption, dielectric, and dispersion parameters have been calculated and discussed.

Purpose: To correct maternal breathing and fetal bulk motion during fetal 4D flow MRI.
Methods: A Doppler-ultrasound fetal cardiac-gated free-running 4D flow acquisition was corrected post hoc for maternal respiratory and fetal bulk motion in separate automated steps, with optional manual intervention to assess and limit fetal motion artifacts. Compressed-sensing reconstruction with a data outlier rejection algorithm was adapted from previous work.
Analysis and characterization of interhypothalamic adhesions in adults: No longer only a pediatric finding.

Department of Radiology, Medical School, University of Minnesota, USA.
Background And Purpose: Inter-hypothalamic adhesions (IHAs) are parenchymal tissue bridges traversing the third ventricle, previously reported only in the pediatric population. We aim to understand the prevalence of IHA in the adult population, assess their size and location, and ultimately investigate whether IHA volumes correlate with age.
Materials And Methods: Patients who underwent routine high-resolution 3D T2WI MRI studies of the temporal bone/internal auditory canal at an otolaryngology clinic between 2008 and 2014 were consecutively selected.

Acute kidney injury (AKI) resulting from cisplatin (Cs) chemotherapy presents a significant challenge in clinical management. The study aimed to fabricate a novel compound Polyvinylpyrrolidone-catechol-derived chitosan nanoconjugates (PCChi-NC) for targeting Cs-induced AKI. Characterization studies utilizing UV-visible spectrophotometry, FT-IR, XRD, and TEM revealed a spherical morphology with diameters ranging from 20 to 60 nm.

Article Synopsis
- ZnO/Ag hollow particles were created using a one-step spray pyrolysis method to improve antibacterial activity and promote wound healing.
- The materials were characterized through techniques like XRD, TEM, and XPS, confirming their hollow structure and even distribution of silver nanoparticles, which enhance light absorption due to their unique properties.
- Antibacterial tests showed that these composites were significantly more effective against bacteria, including MRSA, under visible light, as further analyzed by EPR spectroscopy which indicated the generation of reactive oxygen species contributing to their antibacterial action.
