BACKGROUND: Currently the available techniques for the placement of nasoenteric feeding tube (NET), utilizing transnasal gastroscope are fast and tolerable, which is known as the most popular method. However, lots of hospitals don't have this endoscopic system. Bronchoscope, which is the basic respiratory endoscope, not only has the advantages of transnasal endoscopy, but also is popular in common hospitals. We used oxygen instillation as air supply plant of the bronchoscope, which broke its application limitation in digestive tract...

In a patient undergoing thoracoscopic esophagectomy and concomitant wedge resection, an iatrogenic lesion in the left main bronchus was observed following deflation of the right lung. Because the bronchial cuff of the double-lumen tube was visible through the lesion, repair was only possible after deflation of the bulging cuff. Positive pressure ventilation would result in air leakage jeopardizing ventilation and oxygenation. This challenging situation was resolved using the Ventrain device to oxygenate the patient through a small-bore catheter placed through the lumen beyond the bronchial defect...

INTRODUCTION: Modern perioperative care principles in elective colorectal surgery have already been established by international surgical authorities. Nevertheless, barriers to the introduction of routine evidence-based clinical care and changing dogmas still exist. One of the factors is the surgeon. AIM: To assess perioperative care trends in elective colorectal surgery among general surgery consultants in surgical departments in Malopolska Voivodeship, Poland...

Rapid surge of interest for carbon nanotube (CNT) in the last decade has made it an imperative member of nanomaterial family. Because of the distinctive physicochemical properties, CNTs are widely used in a number of scientific applications including plant sciences. This review mainly describes the role of CNT in plant sciences. Contradictory effects of CNT on plants physiology are reported. CNT can act as plant growth inducer causing enhanced plant dry biomass and root/shoot lengths. At the same time, CNT can cause negative effects on plants by forming reactive oxygen species in plant tissues, consequently leading to cell death...

Composite resins are predominantly marketed in developing countries in tube form, and the contents of the tube may be used in numerous procedures for different patients. This represents a problem because of the risk of cross-contamination. This study aimed to evaluate contamination in vitro of the internal contents of composite resin tubes in the dental clinics of a higher-education institution, as well as the effect of photoactivation on the level of contamination. Twenty-five tubes containing composite resin were randomly chosen (by lottery)...

BACKGROUND: Unilateral incompatibility (UI) is an asymmetric reproductive barrier that unidirectionally prevents gene flow between species and/or populations. UI is characterized by a compatible interaction between partners in one direction, but in the reciprocal cross fertilization fails, generally due to pollen tube rejection by the pistil. Although UI has long been observed in crosses between different species, the underlying molecular mechanisms are only beginning to be characterized...

Congenital heart disease (CHD) represents the most prevalent inborn anomaly. Only a minority of CHD cases are attributed to genetic causes, suggesting a major role of environmental factors. Nonphysiological hypoxia during early pregnancy induces CHD, but the underlying reasons are unknown. Here, we have demonstrated that cells in the mouse heart tube are hypoxic, while cardiac progenitor cells (CPCs) expressing islet 1 (ISL1) in the secondary heart field (SHF) are normoxic. In ISL1+ CPCs, induction of hypoxic responses caused CHD by repressing Isl1 and activating NK2 homeobox 5 (Nkx2...

BACKGROUND: A small tube may facilitate tracheal intubation and improve surgical access. We describe our initial experience with the Tritube(®) that is a novel cuffed endotracheal tube with a 2.4 mm internal diameter. METHODS: The Tritube(®) was used in seven adult Ear-Nose-and Throat surgical patients with airway narrowing or whose surgical access was facilitated by this small-bore endotracheal tube. Ventilation through Tritube(®) is performed with the manually operated Ventrain(®) -ventilator that allows active suctioning during expiration, therefore facilitating normoventilation through small diameter airways...

As non-communicable diseases such as type 2 diabetes mellitus have their roots in prenatal development and conditions such as maternal gestational diabetes (GDM), we aimed to test this hypothesis in primary cells derived from the offspring of GDM mothers compared to control subjects. We have assessed primary umbilical cord derived cells such as human umbilical vein endothelial cells (HUVECs) and Wharton's jelly derived mesenchymal stem cells (WJMSCs) from both, the offspring of GDM and non-GDM mothers. We have compared the primary isolates in cell based assays measuring proliferation, mitochondrial oxygen consumption, and the ability to support blood vessel growth...

The performance of a novel low-maintenance tube reactor for ultrasonic treatment of sludge has been evaluated. The effects of sonication on the release of soluble chemical oxygen demand (sCOD) and anaerobic digestibility of raw and digested sewage sludge as well as agricultural sludge were studied. Results suggest that solubilization and digestibility is dependent on both type of sludge and the energy input. Digested and raw sludge showed high degree of solubilization, however, methane production was only increased for digested sludge...

CASE DESCRIPTION A 4-hour-old 6.3-kg (13.9-lb) female alpaca cria was evaluated because of severe respiratory distress and difficulty nursing since birth. CLINICAL FINDINGS The cria had open-mouth breathing and cyanotic membranes, with no airflow evident from either nostril. Supplemental oxygen was delivered, and the patient was anesthetized and intubated orotracheally; a CT evaluation of the head confirmed bilateral membranous obstruction of the nasal cavities, consistent with complete bilateral choanal atresia...

Neonatal intubation is one of the most common procedures performed by neonatologists, however, the procedure is extremely difficult, and high risk. Neonates who endure the procedure often experience adverse events, including bradycardia and severe oxygen desaturations. Because of low first attempt success rates, neonates are often subjected to multiple intubation attempts before the endotracheal tube is successfully placed. These factors conspire to make intubation one of the most dangerous procedures in neonatal medicine...

Aberrant neovascularization supports nutrients and the oxygen microenvironment in tumour growth, invasion and metastasis. Recapitulation of functional microvascular structures in vitro could provide a platform for the study of vascular conditions. Sulforaphane (SFN), an isothiocyanate, has been reported to possess chemopreventive properties. In the present study, the effects of SFN on cell proliferation and tubular formation have been investigated using endothelial cells (ECs) and pericytes in coculture. SFN showed a dose-dependent inhibition on the growth of ECs and pericytes with IC50 values 46...

Proliferative diabetic retinopathy (PDR) is a common cause of blindness in the developed world's working adult population, and affects those with type 1 and type 2 diabetes mellitus. We identified Runt-related transcription factor 1 (RUNX1) as a gene upregulated in CD31+ vascular endothelial cells obtained from human PDR fibrovascular membranes (FVM) via transcriptomic analysis. In vitro studies using human retinal microvascular endothelial cells (HRMECs) showed increased RUNX1 RNA and protein expression in response to high glucose whereas RUNX1 inhibition reduced HRMEC migration, proliferation, and tube formation...

A 46-year-old man underwent redo bilateral sequential lung transplantation for rapidly progressive bronchiolitis obliterans syndrome that developed 3.5 years after initial transplantation. In the operating room, he was sedated and intubated with a dual lumen endotracheal tube with subsequent single right-lung ventilation and left allograft implantation. His pulmonary arterial pressure became elevated with reperfusion of the newly implanted left lung, which required initiation of cardiopulmonary bypass to facilitate implantation of the right lung...
