Ricinoleic acid (12-hydroxy-octadeca-9-enoic acid) is a major unusual fatty acid in castor oil. This hydroxy fatty acid is useful in industrial materials. This unusual fatty acid accumulates in triacylglycerol (TAG) in the seeds of the castor bean (Ricinus communis L.), even though it is synthesized in phospholipids, which indicates that the castor...

Insulin resistance is the primary cause responsible for type 2 diabetes. Phosphatase and tensin homolog (PTEN) plays a negative role in insulin signaling and its inhibition improves insulin sensitivity. Metformin is a widely used insulin-sensitizing drug; however, the mechanism by which metformin acts is poorly understood. To gain insight into the...

Metformin is a major oral anti-diabetic drug and is known as an insulin sensitizer. However, the mechanism by which metformin acts is unclear. In this study, we found that AICAR, an AMPK activator, and metformin increased the expression of Rab4 mRNA and protein levels in skeletal muscle C2C12 cells. The promoter activity of Rab4 was increased by me...

The tracheary elements (TEs) of the xylem serve as the water-conducting vessels of the plant vascular system. To achieve this, TEs undergo secondary cell wall thickening and cell death, during which the cell contents are completely removed. Cell death of TEs is a typical example of developmental programmed cell death that has been suggested to be a...

... Rather than reverting to manual ventilation using a manual resuscitation device, choosing an appropriate ventilator strategy for the patient already undergoing mechanical ventilation when chest compressions are performed frees up hands that can be better used. 35 The "six-dial strategy" described by Sahu et al 36 in Table 2 is a useful strategy to optimize ventilation using conventional mechanical ventilators during cardiopulmonary resuscitation. Although the fraction of inspired oxygen is not described as part of this strategy, it is assumed ...
... Furthermore, there is currently no factor that has demonstrated sufficient accuracy in predicting the outcome of pediatric post-arrest survival [6]. Among the biochemical markers of pediatric cardiac arrest, researches have suggested that neuronspecific enolase (NSE), serum lactate and pH measured within the first 24 hours after arrest, and the delta neutrophil index are associated with patient survival and neurological prognosis [6][7][8]. However, the specific cutoff values for each biological marker are not well-established, and there is a limited amount of research on biological markers during cardiac arrest. ...
... There are important differences in the infant, child, adolescent and adult anatomy and physiology that would influence the management of cardiopulmonary arrest. [1][2][3][4][5][6][7] Paediatric cardiac arrest outcomes, especially for infants, remain generally poor. [1][2][3] The paediatric life support taskforce of the International Liaison Committee on Resuscitation (ILCOR) regularly reviews and updates available scientific evidence to make treatment recommendations on paediatric life support. ...
... We found that the global ASIR of FBs has increased since 2010, especially in high, high-middle, and middle SDI regions, which may be closely related to socioeconomic development, changes in people's lifestyles and diets, and the development and progress of medical diagnostic technology. A study in Korea found that the incidence of FBs is increasing yearly, which is consistent with our research results [25]. China, with a population of 1.42 billion, is the most populous country in the world. ...
... 9 Although previous studies showed even higher rates of CAD in these patients, the optimal treatment strategy for patients with an initial non-shockable rhythm remained debateable, since these were excluded from the COACT trial. 16,17 The recently published randomized controlled TOMAHAWK trial aimed to address this issue by investigating the association of early CAG on mortality independent of initial rhythm but failed to demonstrate reduced mortality after early CAG as well. 18 Two recent meta-analyses showed the superiority of selective late and early CAG compared with no CAG regarding mortality and neurological outcome but found no difference between early and selective late CAG. ...

... A categoria "Déficit na capacitação profissional" ressalta a carência de elementos para que os enfermeiros possam elaborar uma assistência adequada às vítimas de violência. Nota-se que nos estudos E7, E8 e E9 discorre sobre as dificuldades de alguns enfermeiros relacionadas a identificação dos casos suspeitos de violência (Cleek et al., 2019;Elarousy;Abed, 2019;Paek et al., 2019). ...
... However, several previous studies on pupil examinations upon hospital arrival have shown that even if negative PLR and mydriasis are observed, their sensitivity regarding neurological prognosis is low and insufficient to predict poor neurological prognosis, which is an important decision [11,12]. On the other hands, it has occasionally been observed that pupillary findings change after the return of spontaneous circulation (ROSC) or extracorporeal membrane oxygenation (ECMO) establishment in patients with OHCA in whom poor prognosis was inferred from pupillary findings at the time of initial evaluation [13,14]. Despite the potential relevance to prognosis, the association between these changes in pupillary examination and the neurological prognosis in patients undergoing ECPR has not been well established. ...
... Strategies to increase the detection of child abuse in EDs to prevent devastating outcomes have been previously described, including checklists, the development of new screening tools [6,24,[39][40][41][42], testing of existing tools for their usefulness [15,43], implementation of staff training [15,31,44], and automatic involvement of CPS at certain defined diagnoses [45]. Checklists covering the indicators of risk for CAN have been previously shown to increase the rate of suspected but not confirmed cases of child maltreatment, the awareness of CAN, and the documentation of suspected cases [5]. ...
... A decrease in incidence was subsequently observed. In older adolescents over 11 years of age, the most common cause of accidents was sport-related activities, which was also observed in other studies [19,20]. Similar results were found for accidents at home. ...
