Nonsurgical Removal of Improvised Nasogastric Tubes Entrapped in the Urethra in Two Male Dogs.

In two castrated male dogs, entrapment of a nasogastric feeding tube, which had been used as an improvised urethral catheter, occurred during intermittent urethral catheterization. In both cases, multiple failed attempts to remove the catheter raised concerns about catheter entrapment, which was subsequently confirmed via abdominal radiography. To facilitate removal, both dogs were placed under deep sedation using IV butorphanol (0.

Cardiovascular and Respiratory Effects of Increased Intra-Abdominal Pressure with and without Dexmedetomidine in Anesthetized Dogs.

Intra-abdominal pressure (IAP) elevation during capnoperitoneum can cause adverse cardiovascular and respiratory effects. This study aimed to determine if a sequentially increased IAP affects cardiovascular and respiratory variables in anesthetized dogs and evaluate the effects of the constant-rate infusion of dexmedetomidine (Dex) on cardiovascular and respiratory variables with increased IAP. Five dogs were anesthetized and instrumented, and a Veress needle was equipped to adjust the IAP using a carbon dioxide insufflator.

Ultra-Stable and Highly Efficient White Light Emitting Diodes through CsPbBr Perovskite Nanocrystals-Silica Composite Phosphor Functionalized with Surface Phenyl Molecules.

Poor stability of CsPbBr perovskite nanocrystals (NCs) to moisture/heat/light has significantly limited their application as a green phosphor, despite their outstanding luminescent properties. Here, a remarkably stable CsPbBr NCs-silica composite phosphor functionalized with surface phenyl molecules (CsPbBr -SiO ) is synthesized by controlling low-temperature hydrolysis and condensation reaction of perhydropolysilazane in the presence of CsPbBr NCs followed by phenyl-functionalization. Through the process, CsPbBr NCs are confined in a compact silica matrix, which is impermeable to H O.

Breast cancer detection by analyzing the volatile organic compound (VOC) signature in human urine.

A rising number of authors are drawing evidence on the diagnostic capacity of specific volatile organic compounds (VOCs) resulting from some body fluids. While cancer incidence in society is on the rise, it becomes clear that the analysis of these VOCs can yield new strategies to mitigate advanced cancer incidence rates. This paper presents the methodology implemented to test whether a device consisting of an electronic nose inspired by a dog's olfactory system and olfactory neurons is significantly informative to detect breast cancer (BC).

Development of Wheel Pressure Control Algorithm for Electronic Stability Control (ESC) System of Commercial Trucks.

This paper presents a wheel cylinder pressure control algorithm for application to the vehicle electronic stability control (ESC) systems for commercial trucks. An ESC system is an active system that improves the driving stability by distributing the appropriate braking pressure to each wheel, which is an essential system for safe driving. It is important that the ESC system, through proper braking pressure supply, delivers the correct pressure under control.

Opuntia humifusa ameliorated cerulein-induced acute pancreatitis.

Objective: The aim of this study was to evaluate the effects of Opuntia humifusa (OH) on cerulein-induced acute pancreatitis (AP).

Methods: Acute pancreatitis was induced via intraperitoneal injection of cholecystokinin analog cerulein (50 μg/kg). In the OH pretreatment group, OH was administered intraperitoneally (100, 250, or 500 mg/kg) 1 hour before first cerulein injection.

The regulatory mechanism of β-eudesmol is through the suppression of caspase-1 activation in mast cell-mediated inflammatory response.

β-Eudesmol is sesquiterpenoid alcohol which contains the rhizome of Atractylodes lancea. Although it has multiple pharmacological effects, the anti-inflammatory effect of β-eudesmol and its molecular mechanisms are poorly elucidated. In this study, we investigated the regulatory mechanism of β-eudesmol on mast cell-mediated inflammatory response.

Induction of nitric oxide & tumour necrosis factor-alpha by Psoralea corylifolia.

Background & Objectives: Psoralea corylifolia (PC) is an herb widely used in medicine for the treatment of a variety of ailment. PC is also known to have immunomodulatory activity. However, its mechanism of action is not known.
