Pritesh Jain, Dilip Kumar Pal
Pelvic retroperitoneum is a bizarre location of an epidermoid cyst and obstructive voiding caused by it even being stranger. Voiding symptoms related to such an abnormal location of cyst are extremely rare and literature that taps into such cases is scarce. We are presenting here a case of 26-year-old man who was presented with obstructive lower urinary tract symptoms and chronic constipation. On evaluation, he was found to have well-defined cyst in pelvic retroperitoneum. Complete excision of the cyst was done; histopathology confirmed it as an epidermoid cyst...

INTRODUCTION AND OBJECTIVES: Vesicoureteral reflux (VUR) has been one of the defining conditions unique to pediatric urology since its inception. The clinical implications of this disease process depend on intrinsic patient factors such as age, genetics, epigenetics, voiding habits, anatomic anomalies, and extrinsic factors such as the pathogenicity of infectious agents. Knowledge about its natural history, the implications of conservative and surgical management, and their associated outcomes have evolved dramatically over time...

BACKGROUND: Convenient, reproducible, and rapid preservation of unique biological specimens is pivotal to their use in microbiome analyses. As an increasing number of human studies incorporate the gut microbiome in their design, there is a high demand for streamlined sample collection and storage methods that are amenable to different settings and experimental needs. While several commercial kits address collection/shipping needs for sequence-based studies, these methods do not preserve samples properly for studies that require viable microbes...

A cloud of nanodust particles is created in a reactive argon-acetylene plasma. It is then transformed into a dusty magnetized argon plasma. Plasma parameters are obtained with the dust-density wave diagnostic introduced by Tadsen et al. [Phys. Plasmas 22, 113701 (2015)10.1063/1.4934927]. A change from an open to a cylindrically enclosed nanodust cloud, which was observed earlier, can now be explained by a stronger electric confinement if a vertical magnetic field is present. Using two-dimensional extinction measurements and the inverse Abel transform to determine the dust density, a redistribution of the dust with increasing magnetic induction is found...

Understanding the interplay between ordered structures and substrate curvature is an interesting problem with versatile applications, including functionalization of charged supramolecular surfaces and modern microfluidic technologies. In this work, we investigate the two-dimensional packing structures of charged particles confined on a pinched sphere. By continuously pinching the sphere, we observe cleavage of elongated scars into pleats, proliferation of disclinations, and subsequently, emergence of a depletion zone at the negatively curved waist that is completely void of particles...

Lithium metal anodes are considered to be the most promising anode material for next-generation advanced energy storage devices due to their high reversible capacity and extremely low anode potential. Nevertheless, the formation of dendritic Li, induced by the repeated breaking and repairing of solid electrolyte interphase layers, always causes poor cycling performance and low coulombic efficiency, as well as serious safety problems, which have hindered the practical application of Li anodes for a long time...

Neurogenic bladder occur as a consequence of several conditions, most commonly posterior urethral valves syndrome, spina bifida, tethered cord, sacral agenesis, and Arnold-Chiari malformation. It is characterized by diminished bladder capacity and/or reduced compliance, associated with high-pressure voiding that can lead to deterioration of renal function if left untreated. When medical management fails, bladder reconstruction with bowel (aumentation ileocystoplasty) becomes the treatment of choice for these patients...

INTRODUCTION: Holmium laser enucleation of the prostate (HoLEP) offers superior voiding outcomes to traditional transurethral resection and less morbidity than open simple prostatectomy. Likewise, HoLEP has been determined to result in excellent outcomes regardless of gland size. We present a step-by-step surgical approach to HoLEP describing both the traditional enucleation technique and a modified "top-down" surgical technique. MATERIALS AND METHODS: In this video, two techniques are presented that were performed by two (A...

Nanoporous metallic networks are a group of porous materials made of solid metals with suboptical wavelength sizes of both particles and voids. They are characterized by unique optical properties, as well as high surface area and permeability of guest materials. As such, they attract a great focus as novel materials for photonics, catalysis, sensing, and renewable energy. Their properties together with the ability for scaling-up evoke an increased interest also in the industrial field. Here, fabrication techniques of large-scale metallic networks are discussed, and their interesting optical properties as well as their applications are considered...

PURPOSE OF REVIEW: Treatment of anterior urethral stricture disease (USD) has shifted from endoscopic approaches to urethroplasty with significantly higher success rates among reconstructive urologists. This academic stance has led to a critical evaluation of "success" and developing disease-specific instruments to assess surgical outcomes focusing on patients' satisfaction rather than the historical goal of avoiding secondary procedures. RECENT FINDINGS: Many disease non-specific and/or non-validated patient-reported outcome measures (PROMs) have been utilized to evaluate the voiding symptoms and sexual of function of patients after urethroplasty in the literature...

Rhizosphere-associated Pseudomonas fluorescens are known plant growth promoting (PGP) and mycorrhizal helper bacteria (MHB) of many plants and ectomycorrhizal fungi. We investigated the spatial and temporal dynamics of colonization of mycorrhizal and non-mycorrhizal Aspen seedlings roots by the P. fluorescens strains SBW25, WH6, Pf0-1, and the P. protegens strain Pf-5. Seedlings were grown in laboratory vertical plates systems, inoculated with a fluorescently labeled Pseudomonas strain, and root colonization was monitored over a period of 5 weeks...

Diabetic cardiomyopathy refers to a unique set of heart-specific pathological variables induced by hyperglycemia and insulin resistance. Given that cardiovascular disease (CVD) is the leading cause of death in the world, and type 2 diabetes incidence continues to rise, understanding the complex interplay between these two morbidities and developing novel therapeutic strategies is vital. Two hallmark characteristics specific to diabetic cardiomyopathy are diastolic dysfunction and cardiac structural mal-adaptations, arising from cardiac cellular responses to the complex toxicity induced by hyperglycemia with or without hyperinsulinemia...

The mechanical properties of the urinary bladder wall are important to understand its filling-voiding cycle in health and disease. However, much remains unknown about its mechanical properties, especially regarding regional heterogeneities and wall microstructure. The present study aimed to assess the regional differences in the mechanical properties and microstructure of the urinary bladder wall. Ninety (n=90) samples of porcine urinary bladder wall (ten samples from nine different locations) were mechanically and histologically analysed...

In this article, we study the size-dependent interactions of quasi-spherical nanocrystals with voids of concave nanoparticles of complementary sizes and shapes. Experimental insights into a system with key and lock particles with smaller dimensions than 15 nm are presented, which provide evidence for key-lock specific interaction on this length scale. Using depletion attraction as a driving force, the key-lock interaction is shown to be reversible and independent of the material composition of the key particles...

In this work, the evolution of PdAg and PdAuAg alloy nanostructures is demonstrated on sapphire (0001) via the solid-state dewetting of multi-metallic thin films. Various surface configurations, size, and arrangements of bi- and tri-metallic alloy nanostructures are fabricated as a function of annealing temperature, annealing duration, film thickness, and deposition arrangements such as bi-layers (Pd/Ag), tri-layers (Pd/Au/Ag), and multi-layers (Pd/Au/Ag × 5). Specifically, the tri-layers film shows the gradual evolution of over-grown NPs, voids, wiggly nanostructures, and isolated PdAuAg alloy nanoparticles (NPs) along with the increased annealing temperature...
