To make investigational drug candidates available to patients sooner, timelines for drug development are becoming shorter. Synthesis route scouting for active pharmaceutical ingredients (API) and drug product development often must occur simultaneously, requiring formulators to make decisions regarding drug product process selection before commercial API route finalization. Alternatively, the formulation strategy may be locked, thereby constraining drug substance processes with strict API attribute requirements.

Liquid-liquid phase separation, whereby two liquids spontaneously demix, is ubiquitous in industrial, environmental, and biological processes. While isotropic fluids are known to condense into spherical droplets in the binodal region, these dynamics are poorly understood for structured fluids. Here, we report the unique observation of condensate networks, which spontaneously assemble during the demixing of a mesogen from a solvent.

Materials And Methods: The specimens after surgical treatment of 190 patients with ccRCC were analyzed. In all cases, nephron-sparing surgery (NSS) was performed through laparoscopic access.
Herein is described the development of a large-scale manufacturing process for molnupiravir, an orally dosed antiviral that was recently demonstrated to be efficacious for the treatment of patients with COVID-19. The yield, robustness, and efficiency of each of the five steps were improved, ultimately culminating in a 1.6-fold improvement in overall yield and a dramatic increase in the overall throughput compared to the baseline process.

Materials And Methods: The study included five patients with kidney tumors. The patients were treated in the Urology Clinic of I.
Aim: To investigate the effectiveness and benefits of using 3D planning and virtual surgery in the management of patients with localized renal carcinoma undergoing laparoscopic surgery.
Materials And Methods: A retrospective analysis was performed on 558 patients with renal cell carcinoma (RCC) who underwent surgical treatment at the Clinic of Urology, I.M.
Aim: To develop a non-biological 3D printed simulator for training and preoperative planning in percutaneous nephrolithotripsy (PCNL), which allows doctors to master and perform all stages of the operation under ultrasound and fluoroscopy guidance.
Materials And Methods: The 3D model was constructed using multislice spiral computed tomography (MSCT) images of a patient with staghorn urolithiasis. The MSCT data were processed and used to print the model.
Aim: To evaluate the possibility of using 3D-printing in the management of patients with localized kidney cancer.
Materials And Methods: The study comprised five patients with localized kidney cancer who were treated at the Urology Clinic of the I.M.
The purpose of this article is to outline the role and possible applications of 3D printing in urology. At present, this technique provides the opportunity to choose the individual strategy of patient management, to conduct preoperative planning and surgical rehearsal; for medical specialists to reduce the learning curve in mastering modern complex surgical techniques, and for doctors and students to improve understanding of pathological processes in the kidney and the prostate gland.

X-ray diffraction data were collected from oriented calf-thymus DNA fibers in the relative humidity range of 98%-70%, during which DNA undergoes the B- to A-form transition. Coexistence of both forms was observed over a finite humidity range at the transition.
