A commonly heard concern in the Ross procedure, where a diseased aortic valve is replaced by the patient's own pulmonary valve, is the possibility of pulmonary autograft dilatation. We performed a biomechanical investigation of the use of a personalized external aortic root support or exostent as a possibility for supporting the autograft. In ten sheep a short length of pulmonary artery was interposed in the descending aorta, serving as a simplified version of the Ross procedure. In seven of these cases, the autograft was supported by an external mesh or so-called exostent...

Intestinal malrotation places pediatric patients at the risk of midgut volvulus, a complication that can lead to ischemic bowel, short gut syndrome, and even death. Even though the treatments for symptomatic patients of this complication are clear, it is still a challenge to identify asymptomatic patients who are at a higher risk of midgut volvulus and decide on a suitable course of treatment. Development of an accurate computerized model of this intestinal abnormality could help in gaining a better understanding of its integral behavior...

BACKGROUND: Neutrophil extracellular traps (NETs) are released when neutrophils encounter infectious pathogens, especially during sepsis. Additionally, NETosis occurs during venous and arterial thrombosis, disseminated intravascular coagulation, and trauma. OBJECTIVE: We tested if hemodynamic forces trigger NETosis during sterile thrombosis. METHODS: NETs were imaged with Sytox-green during microfluidic perfusion of Factor XIIa-inhibited or thrombin-inhibited human whole blood over fibrillar collagen (± tissue factor)...

Background: Previous reports suggest that 5-hydroxytryptamine (5-HT) might play a role in the antidepressant actions of (R,S)-ketamine. However, its role in the antidepressant actions of (R)-ketamine, which is more potent than (S)-ketamine, is unknown. This study was conducted to examine whether 5-HT depletion affects the antidepressant actions of (R)-ketamine in a chronic social defeat stress (CSDS) model. Methods: An inhibitor of 5-HT synthesis, para-chlorophenylalanine methyl ester hydrochloride (PCPA; 300 mg/kg, twice daily for 3 consecutive days), or vehicle was administered to control and CSDS susceptible mice...

Ghrelin is a 28-amino acid polypeptide that regulates feeding, glucose metabolism and emotionality (stress, anxiety and depression). Plasma ghrelin circulates as desacyl ghrelin (DAG) or in an acylated form, acyl ghrelin (AG), through the actions of Ghrelin -O-Acyltransferase (GOAT), exhibiting low or high affinity, respectively, for the growth hormone secretagogue receptor (GHSR1a). We investigated the role of endogenous AG, DAG and GHSR1a signaling on anxiety and stress responses using ghrelin knockout (Ghr KO), GOAT KO, and Ghsr-stop-floxed (Ghsr null) mice...

Background and Aims: Aridification is considered a selective pressure that might have influenced plant diversification. It is suggested that plants adapted to aridity diversified during the Miocene, an epoch of global aridification (≈15 million years ago). However, evidence supporting diversification being a direct response to aridity is scarce, and multidisciplinary evidence, besides just phylogenetic estimations, is necessary to support the idea that aridification has driven diversification...

REVIEW
Hong Xu, Juan J Carrero
This review provides an overview of insulin resistance (IR) in patients with chronic kidney disease (CKD). IR is a pathological state in which target tissues fail to respond normally to insulin. IR is understood as a consequence of CKD and its prevalence rises particularly in advanced CKD stages. Mechanisms leading to IR are complex and multifactorial, involving post-receptor signaling defects, unhealthy lifestyles, metabolic acidosis, inflammation, oxidative stress, vitamin D deficiency, anemia, and uremic toxicity, as shown by human and experimental studies over the last 30 years...

PURPOSE: Virtual reality (VR) technology is an effective tool in treatment of acute pain. Numerous studies show the effectiveness of this method both in a clinical context and in the laboratory. However, research results on the effectiveness of VR in pediatric venipuncture pain is not conclusive-not all studies report the analgesic effect of VR. In addition to testing effectiveness of VR, we also assess the usability of a novel hands-free interface. DESIGN AND METHODS: Patients of paediatric nephrology clinic (N = 38; mean age 11 years, range 7-17) participated in a posttest only between group quasi-experimental study...

The SWEET (sugars will eventually be exported transporter) family is a newly characterized group of sugar transporters. In plants, the key roles of SWEETs in phloem transport, nectar secretion, pollen nutrition, stress tolerance, and plant-pathogen interactions have been identified. SWEET family genes have been characterized in many plant species, but a comprehensive analysis of SWEET members has not yet been performed in wheat. Here, 59 wheat SWEETs (hereafter TaSWEETs) were identified through homology searches...

Skin aging is associated with alterations of surface texture, sebum composition and immune response. Mechanical stress induces repair mechanisms, which may be dependent on the age and quality of the skin. The response to mechanical stress in young and aged individuals, their subjective opinion and objective effectiveness of skin care products were evaluated by biophysical skin quality parameters (stratum corneum hydration, transepidermal water loss, skin pH, pigmentation and erythema) at baseline, 1, 6, 24hours and 7days at the forearms of 2 groups of healthy volunteers, younger than 35 years (n=11) and older than 60 years (n=13)...

English-learning infants attend to lexical stress when learning new words. Attention to lexical stress might be beneficial for word learning by providing an indication of the grammatical class of that word. English disyllabic nouns commonly have trochaic (strong-weak) stress, whereas English disyllabic verbs commonly have iambic (weak-strong) stress. We explored whether 17-month-old infants use word stress to resolve an ambiguous labeling event where objects and actions are equally plausible referents. Infants were habituated to 2 words paired with 2 objects, with each object performing a distinct path action...

OBJECTIVE: Lifetime trauma, relationship adversities, and emotional conflicts are elevated in primary care patients with medically unexplained symptoms (MUS), and these risk factors likely trigger or exacerbate symptoms. Helping patients disclose stressors, increase awareness and expression of inhibited emotions, and link emotions to physical symptoms may improve health. We developed an emotional awareness and expression interview that targets stressful life experiences and conflicts and then tested its effects on primary care patients with MUS...
