Fatal nephrobronchial fistula arising from xanthogranulomatous pyelonephritis: a case report.

Introduction: Nephrobronchial fistula is an exceptionally rare complication of renal infections, including the uncommon xanthogranulomatous pyelonephritis. Existing literature is limited to a few case reports, with antibiotic therapy and nephrectomy being the preferred treatments.

Case: We present the case of a 63-year-old woman with a history of recurrent xanthogranulomatous pyelonephritis in her right kidney, requiring drainage through lumbotomy.

Correlated Anion Disorder in Heteroanionic Cubic TiOF.

Resolving anion configurations in heteroanionic materials is crucial for understanding and controlling their properties. For anion-disordered oxyfluorides, conventional Bragg diffraction cannot fully resolve the anionic structure, necessitating alternative structure determination methods. We have investigated the anionic structure of anion-disordered cubic (ReO-type) TiOF using X-ray pair distribution function (PDF), F MAS NMR analysis, density functional theory (DFT), cluster expansion modeling, and genetic-algorithm structure prediction.

Synthesis of Novel Triazine-Based Chalcones and 8,9-dihydro-7-pyrimido[4,5-][1,4]diazepines as Potential Leads in the Search of Anticancer, Antibacterial and Antifungal Agents.

This study presents the synthesis of four series of novel hybrid chalcones ()- and ()- and six series of 1,3,5-triazine-based pyrimido[4,5-][1,4]diazepines (-)- and the evaluation of their anticancer, antibacterial, antifungal, and cytotoxic properties. Chalcones ,, ,, ,-, - and the pyrimido[4,5-][1,4]diazepines ,, , ,,-, ,,- exhibited outstanding anticancer activity against a panel of 60 cancer cell lines with GI values between 0.01 and 100 μM and LC values in the range of 4.

New pyridine-based chalcones and pyrazolines with anticancer, antibacterial, and antiplasmodial activities.

New pyridine-based chalcones 4a-h and pyrazolines 5a-h (N-acetyl), 6a-h (N-phenyl), and 7a-h (N-4-chlorophenyl) were synthesized and evaluated by the National Cancer Institute (NCI) against 60 different human cancer cell lines. Pyrazolines 6a, 6c-h, and 7a-h satisfied the pre-determined threshold inhibition criteria, obtaining that compounds 6c and 6f exhibited high antiproliferative activity, reaching submicromolar GI values from 0.38 to 0.

In silico prediction and in vitro assessment of novel heterocyclics with antimalarial activity.

The development of new antimalarials is paramount to keep the goals on reduction of malaria cases in endemic regions. The search for quality hits has been challenging as many inhibitory molecules may not progress to the next development stage. The aim of this work was to screen an in-house library of heterocyclic compounds (HCUV) for antimalarial activity combining computational predictions and phenotypic techniques to find quality hits.
