We developed and validated a surgical technique to measure central venous pressure (CVP) in Nile tilapia, and investigated the effects of an acute temperature decrease (from 30 vs. 24 °C) and changes in heart rate (f) using zatebradine hydrocholoride, which decreases intrinsic f on this species' cardiac function. As predicted, f and cardiac output ( ) were ~ 40% lower in the acutely cooled fish, and both groups had very comparable (i.

In an effort to mitigate the effects of such content and to comply with regulatory standards, these studies usually conclude by "debriefing" participants about the content they encountered, on the assumption that doing so will eliminate the effects of exposure. We present evidence showing that this assumption is not always correct.

Article Synopsis
- A surgery-first approach using robotic common bile duct exploration (RBCDE) offers an effective alternative for treating CBD stones in patients with gallbladders, showing equal efficacy at a lower cost compared to traditional methods.
- The RBCDE technique simplifies the process by using a cystic ductotomy and a cholangiogram to identify stones, allowing for targeted removal with different techniques based on stone size.
- This method aims to enhance the adoption of a straightforward, one-stage surgery for CBD stone treatment, overcoming technical limitations associated with traditional laparoscopic procedures.
Article Synopsis
- * In a study, wild schoolmaster snapper were acclimated to 29°C and subjected to a temperature increase while measuring their response under normal oxygen levels and hyperoxia (150% saturation).
- * Results showed that while the fish's critical thermal maximum (CTmax) was around 39°C for both conditions, hyperoxia did improve their metabolic capacity, but it won't provide protection during severe heat waves in coastal environments.
We report results from simultaneous experiments conducted in late 2022 in Belarus, Estonia, Kazakhstan, Russia and Ukraine. The experiments focus on fact-checking misinformation supportive of Russia in the Russia-Ukraine War. Meta-analysis makes clear that fact-checking misinformation reduces belief in pro-Kremlin false claims.
