Direct visual internal urethrotomy: Is it a durable treatment option?

Urology Annals, 2017
Objective: To evaluate the long-term success rate of direct vision internal urethrotomy as a treatment for anterior urethral strictures. Materials and Methods: We retrospectively analyzed the results for patients who underwent internal urethrotomy from ...

Strictures of the female reproductive tract impose fierce competition to select for highly motile sperm [PDF]

arXiv, 2018
Investigating sperm locomotion in the presence of an external fluid flow and geometries simulating the female reproductive tract can lead to a better understanding of sperm motion during the fertilization process. In this study, using a microfluidic device featuring a stricture that simulates the biophysical properties of narrow junctions inside the ...

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery

Advanced Science, EarlyView.
The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

Factors Promoting Development of Fibrosis in Crohn’s Disease

Frontiers in Medicine, 2017
The concepts on the pathophysiology of intestinal fibrosis in Crohn’s disease (CD) have changed in recent years. Some years ago fibrosis was regarded to be a consequence of long-standing inflammation with subsequent destruction of the gut wall matrix ...

Following in the footsteps of E. coli: sperm in microfluidic "strictures" [PDF]

arXiv, 2019
We briefly describe the similarities of the experiments of sperm motion in microfluidic "strictures" by Zafeeani et al. in 2019 (Sci. Adv. 5, eaav21111, 2019) and those by Altshuler et al. in 2013 (Soft Matter 9, 1864, 2013). We shortly discuss the hydrodynamic elements justifying the strong resemblance between the two types of experiments, and suggest

Pade spectroscopy of structural correlation functions: application to liquid gallium [PDF]

, 2015
We propose the new method of fluid structure investigation which is based on numerical analytical continuation of structural correlation functions with Pade approximants. The method particularly allows extracting hidden structural features of non-ordered condensed matter systems from experimental diffraction data.

Long-term complications of continent catheterizable channels: a problem for transitional urologists. [PDF]

, 2018
A majority of the transitional urology patient population have neurogenic bladder and many of these patients have undergone creation of continent catheterizable channels (CCCs) to facilitate bladder emptying.

A core outcome set for localised prostate cancer effectiveness trials [PDF]

, 2017
Objective: To develop a core outcome set (COS) applicable for effectiveness trials of all interventions for localised prostate cancer. Background: Many treatments exist for localised prostate cancer, although it is unclear which offers the ...

STRICTURE OF THE ŒSOPHAGUS. [PDF]

JAMA: The Journal of the American Medical Association, 1883
Mr. Editor: No. 16 of theJournal of the American Medical Associationcontains an interesting article on " Stricture of the Œsophagus," etc., that reminds me of the following case: One year ago Mrs. A. D. Peebles, of near Shelbyville, Ill., was taken with puerperal convulsions, and had three or four M.D.'S called. According to Mr. Peebles statement she

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

Advanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...
