Dual-specificity tyrosine kinase 1A (DYRK1A) is a member of the CMGC family that is linked to a multitude of neuronal development pathways. Both overexpression and insufficiency of this gene are associated with many recognizable disorders, including Down syndrome and DYRK1A-related intellectual disability syndrome which is characterized by distinct physical features with microcephaly and global developmental delay. We report a case of DYRK1A-related intellectual disability syndrome caused by a novel mutation.

To avoid unnecessary surgeries, there is an increasing interest in using radiomics tools to predict histological results, using radiological features. We performed a narrative review to evaluate the use of radiomics in renal mass characterization.

Computational calculations indicate that PNAs modified with these nucleobases enable the formation of highly stable triple helices with no sequence restrictions through multiple hydrogen bonding and π⋅⋅⋅π stacking interactions, without significantly widening the DNA double helix. New synthetic routes were developed to the structures of these fused heterocycles which have rarely been described in the literature.

By profiling the proteome of extracellular vesicles (EVs) from T cells, we have found the chaperonin complex CCT, involved in the correct folding of particular proteins. By limiting CCT cell-content by siRNA, cells undergo altered lipid composition and metabolic rewiring towards a lipid-dependent metabolism, with increased activity of peroxisomes and mitochondria.

Therefore, the aim of this in vitro study was to develop and to assess a new design of biodegradable ureteral stent coated with a silk fibroin matrix for the controlled release of mitomycin C as a chemotherapeutic drug. For this purpose, we assessed the coating of a biodegradable ureteral stent, BraidStent, with silk fibroin and subsequently loaded the polymeric matrix with two formulations of mitomycin to evaluate its degradation rate, the concentration of mitomycin released, and changes in the pH and the weight of the stent.

Recent Findings: Renal cell carcinoma (RCC) represents 3% of the cancers. Nowadays, partial nephrectomy (PN) represents gold standard treatment.
Background: We assessed an antireflux biodegradable heparin-coated ureteral stent (BraidStent-H) in an animal model comparative study after endoscopic treatment of ureteral strictures.
Methods: A total of 24 female pigs underwent initial endoscopic, nephrosonographic, and contrast fluoroscopy assessment of the urinary tract. Afterward, unilateral laparoscopic ureteral stricture model was performed.
We present a clinical case of an asymptomatic 61-year-old man was found to have a left kidney mass. Ultrasound and CT showed a 6 x 5 cms mass with calcifications. Histologic examination of the radical nephrectomy specimen revealed a chromophobe renal cell carcinoma.

A total of 24 female pigs underwent initial endoscopic, nephrosonographic, and contrast fluoroscopy assessment of the urinary tract. Afterward, unilateral iatrogenic perforation in proximal ureter model was performed.

The Lumenis Pulse 120H® laser has a higher system energy, a higher energy per pulse and a higher repetition frequency in relation to other types of lasers, which offers advantages in the treatment of lithiasis.
Objective: To analyze the results that we have obtained with the use of the Lumenis Pulse120H® laser in patients treated by intrarenal retrograde surgery (RIRS).
We present an overview of the onetep program for linear-scaling density functional theory (DFT) calculations with large basis set (plane-wave) accuracy on parallel computers. The DFT energy is computed from the density matrix, which is constructed from spatially localized orbitals we call Non-orthogonal Generalized Wannier Functions (NGWFs), expressed in terms of periodic sinc (psinc) functions. During the calculation, both the density matrix and the NGWFs are optimized with localization constraints.

Likewise, the treatment to be carried out, in these rare cases, is controversial, with respect to opting for radical renal surgery.

Extensive molecular modeling led to an optimized design with perfect complementarity to the Hoogsteen site inside DNA's major groove. A wide range of functional elements can be introduced by minor modifications of the synthetic strategy.

Current training in urological endoscopy lacks a specific training program. However, there is a clear need for a specific and uniform program, which will ensure the training, regardless of the unit where it is carried out. So, the goal is to first evaluate the current model and then bring improvements for update.
