Histotripsy erosion of model urinary calculi.

open access: yesJournal of endourology, 2011
BACKGROUND AND PURPOSE Histotripsy is a pulsed focused ultrasound technology in which initiation and control of acoustic cavitation allow for precise mechanical fractionation of tissues. The present study examines the feasibility of using histotripsy for

The Effect of the Amount and Type of Liquid Intake on Kidney Calculi: A Case-Control Study

open access: yesمجله اپیدمیولوژی ایران, 2015
Background & Objectives: Urinary calculi are a common problem worldwide. The pattern of fluid consumption in healthy people and patients with renal calculi is not totally clear. The aim of this study was to determine the association between the amount of

Covariant first order differential calculus on quantum projective spaces [PDF]

open access: yesarXiv, 1999
We investigate covariant first order differential calculi on the quantum complex projective spaces CP_q^{N-1} which are quantum homogeneous spaces for the quantum group SU_q(N). Hereby, one more well-studied example of covariant first order differential calculus on a quantum homogeneous space is given.

Multiplexed Bio‐detection on an Interferometric Optical Waveguide Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
Multiplexed remote bio‐detection is demonstrated through an image conduit composed of 3012 individual cores and coated with interferometric layers. The proof of concept of biodetection is performed through the kinetic monitoring of two complementary DNA strands hybridization paving the way for applications in multiplex in situ biosensing, and ...

Acute urinary retention in women due to urethral calculi: A rare case.

open access: yesCanadian Urological Association journal = Journal de l'Association des urologues du Canada, 2014
We present a case of a 51-year-old woman with acute urinary retention caused by a urethral calculus. Urethral calculi in women are extremely rare and are usually formed in association with underlying genitourinary pathology.

Leveraging Design of Experiments to Unravel the Amplification Mechanism of Single‐Molecule Wide‐Field Biosensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Detecting single molecules on large interfaces is challenging due to minimal perturbations on the sensing surface. Some biological systems achieve this feat using amplification mechanisms, but their molecular foundations remain unclear. To investigate, a Design of Experiments (DoE) approach examines how pH and ionic strength in conditioning solutions ...

Extensive prostatic calculi in alkaptonuria: An unusual manifestation of rare disease

open access: yesAsian Journal of Urology, 2015
Extensive prostatic calculi in a young man should always elicit the suspicion of alkaptonuria. Although prostatic calculi are seen in chronic prostatitis, chronic pelvic pain syndrome and benign prostate hyperplasia, none of these have prostatic calculi ...

Urinary calculi — atypical source of information on mercury in human biomonitoring

open access: yes, 2012
Chemical analysis of various biological matrices is routinely used for assessment of human exposure to various toxic metals. In this work, 489 samples of urinary calculi originating from almost the whole of The Czech Republic, were collected and ...
