In a patient who has ruptured his oesophagus a major objective should be to prevent access of swallowed material or refluxed gastric contents to the area of the rupture. We describe a tube system, introduced into the oesophagus via a cervical oesophagostomy, which prevents swallowed material from getting to the lower oesophagus and allows a tube to the passed into the stomach for continuous aspiration of gastric contents. To discontinue the diversion, a surgical procedure is not required. The successful use of this tube system in 3 patients is described.

Background: The development of heat transfer devices used for heat conversion and recovery in several industrial and residential applications has long focused on improving heat transfer between two parallel plates. Numerous articles have examined the relevance of enhancing thermal performance for the system's performance and economics. Heat transport is improved by increasing the Reynolds number as the turbulent effects grow.

Aim: Timing of chest tube removal post lung resection is variable in practice and often based on personal experience rather than evidence. The current practice in chest tube management among thoracic surgeons across Canada is so far unknown. Our primary aim was to assess the current status of chest tube removal in Canada in order to uncover potential shortcomings.

Steam condensers are vital components of thermal power plants, responsible for converting turbine exhaust steam back into water for reuse in the power generation cycle. Effective pressure regulation is crucial to ensure operational efficiency and equipment safety. However, conventional control strategies, such as PI, PI-PDn and FOPID controllers, often struggle to manage the nonlinearities and disturbances inherent in steam condenser systems.

Extracellular vesicles (EVs) play a critical role in the development of neural cells in the central nervous system (CNS). Human neural rosettes (hNRs) are radial cell structures that assemble from induced pluripotent stem cells (hiPSCs) and recapitulate some stages of neural tube morphogenesis. Here we show that hiPSCs and hNRs secrete EVs (hiPSC-EVs and hNR-EVs) with distinctive protein cargoes.

Introduction: Anencephaly is a serious developmental defect of the central nervous system in which the brain and cranial vault are grossly malformed. The cerebrum and cerebellum are reduced or absent, but the hindbrain is present. Anencephaly is a part of the neural tube defect spectrum.
