BACKGROUND: Ischemia/reperfusion (I/R) accompanying with the blood supply restored after myocardial infarction. Myocardial I/R injury relieves when autophagy decreased. MicroRNA-34a(miR-34a) regulate autophagy in renal I/R injury model. But whether it can affect cardiac I/R injury remains studying. This study investigated how miR-34a in protecting myocardial cells against I/R injury through inhibit autophagy via regulating tumor necrosis factor α (TNFα) . METHODS: Constructed the I/R model in vivo with Langendorff; treated Neonatal Rat cardiomyocyte to make H/R injury model in vitro with hypoxia/reoxygenation (H/R) method...

AIM: To compare pregnancy outcomes of Syrian refugee women and Jordanian women. BACKGROUND AND INTRODUCTION: In the past few years, thousands of Syrians fled Syria to neighbouring countries such as Jordan as a result of the continuing conflict in their country. Pregnant refugee women are facing many difficulties that increase the prevalence of antenatal complications. However, there is limited awareness of whether Syrian refugee women have different risks of pregnancy outcomes than Jordanian women...

Transient receptor potential vanilloid 4 (TRPV4) is highly expressed in heart and vessels and can be activated during myocardial ischemia/reperfusion (I/R). Recently, we found that treatment with a selective TRPV4 antagonist HC-067047 significantly reduced infarct size, decreased troponin T levels and improved cardiac function in murine model myocardial I/R. This study was undertaken to investigate the mechanism underlying TRPV4-mediated myocardial I/R injury. To mimic myocardial I/R injury, we established a hypoxia/reoxygenation (H/R) model in H9C2 cells and neonatal rat ventricle myocytes (NRVMs) in vitro...

There is a substantial need for novel therapeutics to combat the widespread impact caused by Crytosporidium infection. However, there is a lack of knowledge on which drug pharmacokinetic characteristics are key to generate an in vivo response specifically if systemic drug exposure is crucial for in vivo efficacy. To identify which pharmacokinetic properties are correlated with in vivo efficacy, we generated physiologically based pharmacokinetic (PBPK) models to simulate systemic and gastrointestinal (GI) drug concentrations for a series of bumped kinase inhibitors (BKI) that have nearly identical in vitro potency against Cryptosporidium but display divergent pharmacokinetic properties...

Recent studies have revealed a link between estradiol (E2) and glucose homeostasis. We aimed to assess the association between cord blood hormone levels and the risk of gestational diabetes mellitus (GDM).A total of 204 pregnant women with GDM and 204 pregnant women without GDM (control) were included in the study. Maternal GDM were diagnosed using a 75 g oral glucose tolerance test at 24 to 26 weeks of gestation. Cord blood samples from neonates were collected immediately post delivery. Controls, which were randomly selected from the study population, were matched (cases to controls ratio: 1:1) to cases by age, sex of fetus, and gestational week...

Erin J Breland, Allison R Eberly, Maria Hadjifrangiskou
Extra-intestinal pathogenic E. coli (ExPEC) infections are common in mammals and birds. The predominant ExPEC types are avian pathogenic E. coli (APEC), neonatal meningitis causing E. coli/meningitis associated E. coli (NMEC/MAEC), and uropathogenic E. coli (UPEC). Many reviews have described current knowledge on ExPEC infection strategies and virulence factors, especially for UPEC. However, surprisingly little has been reported on the regulatory modules that have been identified as critical in ExPEC pathogenesis...

Cryptosporidium parvum calcium-dependent protein kinase 1 (CpCDPK1) is a promising target for drug development against cryptosporidiosis. We report a series of low nanomolar CpCDPK1 5-aminopyrazole-4-carboxamide (AC) scaffold inhibitors that also potently inhibit C. parvum growth in vitro Correlation between anti-CpCDPK1 and C. parvum growth inhibition, as previously reported for pyrazolopyrimidines, was not apparent. Nonetheless, lead AC-compounds exhibited a substantial reduction of parasite burden in the neonatal mouse cryptosporidiosis model when dosed at 25 mg/kg...

Hesperidin (HES), a citrus fruit extract, has beneficial effects on various ischemia/reperfusion (I/R) models. Here, we investigated the possible positive effect of hesperetin (HPT), an active metabolite of HES, and identified the potential molecular mechanisms involved in cardiomyocytes H/R-induced injury. To construct the cardiomyocyte model of hypoxia/reoxygenation (H/R) injury, cultured neonatal rat cardiomyocytes were subjected to 3h of hypoxia followed by 3h of reoxygenation. Cell viability and apoptosis were detected...

In the last 20 years, neonatal survival has progressively increased due to the constant amelioration of neonatal medical treatment and surgical techniques. Thus, the number of children with congenital malformations and severe chronic pathologies who need rehabilitative care has progressively increased. Rehabilitation programs for paediatric patients with disorders of voice, speech and language, communication and hearing, deglutition and breathing are not widely available in hospital settings or in long-term care facilities...

Mediastinal enteric duplication cysts are a rare congenital malformation encountered mainly in neonates and infants. It is a distinct entity within the family of foregut duplication cysts. It can present with respiratory distress due to mass effect and hence surgical excision is the preferred treatment. Histologically, it is characterised by a double layered smooth muscle wall with intestinal lining epithelium. We report a case of mediastinal enteric duplication cyst with aberrant pancreatic tissue in a neonate due to its rarity and early presentation...

OBJECTIVES: To identify endocrinologic problems, particularly those concerning growth, in collodion babies (CBs). METHODS: Clinically identified newborn CBs were included in the study group (group 1). Because CBs are generally born premature, small for gestational age (SGA), or both, a control group matched to the study group in terms of gestational age and birthweight (group 2) was also established. Blood specimens were collected from both groups for thyroid function tests and to measure serum growth hormone (GH), insulinlike growth factor 1 (IGF-1) and IGF binding protein-3 (IGFBP-3) levels...

Terrestrial opossums use their semi-prehensile tail for grasping nesting materials as opposed to arboreal maneuvering. We relate the development of this adaptive behavior with ontogenetic changes in myosin heavy chain (MHC) isoform expression from 21 days to adulthood. Monodelphis domestica is expected to demonstrate a progressive ability to flex the distal tail up to age 7 months, when it should exhibit routine nest construction. We hypothesize that juvenile stages (3-7 months) will be characterized by retention of the neonatal isoform (MHC-Neo), along with predominant expression of fast MHC-2X and 2B, which will transition into greater MHC-1β and 2A isoform content as development progresses...

Correct tip location is crucial for a peripherally inserted central catheter (PICC) to maximize the effects of central venous infusion. However, it is difficult to place the tip in a correct location in neonates because of the unreliable estimated length by surface landmark. Therefore, we evaluated the feasibility and safety of an improved intracavitary electrocardiogram (IC-ECG) technique in guiding PICC placement in neonates based on the ratios of P/R wave amplitudes on IC-ECG. The results showed that all of the 32 neonates whose PICCs had been successfully placed and correct tip position verified by chest radiography acquired qualified P wave on IC-ECG...
