To describe the normal electrocardiographic (ECG) patterns and values in unanesthetized rooks ( Corvus frugilegus ), standard bipolar (I, II, and III) and augmented unipolar limb (aVR, aVL, and aVF) lead ECGs were recorded from 10 clinically healthy wild rooks. Wave forms were analyzed in all leads at 50 mm/s and at 10 mm = 1 mV to determine PR, QRS, ST, and QT durations; the net QRS complex; and P and T amplitudes. The polarity of each waveform was tabulated in all leads. The mean electrical axis (MEA) for the frontal plane was counted by using leads II and III...

BACKGROUND: The apoplast plays an important role in plant defense against pathogens. Some extracellular PR-4 proteins possess ribonuclease activity and may directly inhibit the growth of pathogenic fungi. It is likely that extracellular RNases can also protect plants against some viruses with RNA genomes. However, many plant RNases are multifunctional and the direct link between their ribonucleolytic activity and antiviral defense still needs to be clarified. In this study, we evaluated the resistance of Nicotiana tabacum plants expressing a non-plant single-strand-specific extracellular RNase against Cucumber mosaic virus...

Apatinib is a novel and highly selective tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2. Previous studies have suggested that apatinib is safe and effective in some solid tumors. We report one case with advanced hepatocellular carcinoma (HCC), who received apatinib combined with transhepatic arterial chemotherapy and embolization (TACE), and chemotherapy respectively. TACE was administered three times once a month, using lipiodol 10ml, oxaliplatin 150mg, and tegafur 1g. The dose of apatinib was 500 mg/d from day 4 to 24...

Elbasvir/grazoprevir demonstrated high sustained virologic response rates 12 weeks after the end of treatment (SVR12) across five clinical trials in subjects infected with chronic hepatitis C virus (HCV) genotype 1, including those with advanced chronic kidney disease (CKD), and GT4. Despite favorable results overall, the US Food and Drug Administration (FDA) encountered challenging regulatory issues due to the limitations of clinical trial data in certain subpopulations. In GT1a-infected subjects, baseline NS5A resistance-associated polymorphisms emerged as the strongest baseline characteristic associated with diminished SVR12 rates following 12 weeks of elbasvir/grazoprevir treatment...

BACKGROUND: Papillary thyroid cancer (PTC) prevalence is nearly 3 times higher in females than in males. This gender difference suggests that growth and progression of PTC might be influenced by female sex hormones. OBJECTIVES: To analyze the expression of both estrogen receptor (ER)-α and progesterone receptor (PR) by immunohistochemistry in 203 PTC patients. METHODS: ER-α and PR expression was evaluated in paraffin-embedded tumor tissue samples of 45 males and 158 females followed up for 7...

PURPOSE: To examine the association of T-cadherin with pathologic complete response (pCR) after neoadjuvant chemotherapy for locally advanced breast cancer. RESULTS: T-cadherin expression before and after neoadjuvant chemotherapy was similar (P = 0.162). The multivariable analysis indicated that negative T-cadherin expression was independently associated with pCR after neoadjuvant TAC chemotherapy (P = 0.001). MATERIALS AND METHODS: A total of 136 patients with locally advanced breast cancer received four cycles of neoadjuvant TAC chemotherapy (docetaxel + epirubicin + cyclophosphamide), followed by surgery...

BACKGROUND: Vitamin D has neuroprotective and immunomodulatory properties, and deficiency is associated with worse stroke outcomes. Little is known about effects of hypoxia-ischemia or hypothermia treatment on vitamin D status in neonates with hypoxic-ischemic encephalopathy (HIE). We hypothesized vitamin D metabolism would be dysregulated in neonatal HIE altering specific cytokines involved in Th17 activation, which might be mitigated by hypothermia. METHODS: We analyzed short term relationships between 25(OH) and 1,25(OH)2 vitamin D, vitamin D binding protein, and cytokines related to Th17 function in serum samples from a multicenter randomized controlled trial of hypothermia 33(0)C for 48h after HIE birth versus normothermia in 50 infants with moderate to severe HIE...

BACKGROUND: Preterm, very-low-birth-weight (PT-VLBW) neonates are at-risk for metabolic syndrome later in life. At 1-3yrs, they exhibit excessive weight-for-length z-scores (Wt-LZ) and elevated systolic blood pressures (SBP). Serum adipokines are biomarkers of adiposity, but expression in PT-VLBW infants is unclear. We examined the correlation between serum adipokine levels, anthropometric measures and SBP in PT-VLBW neonates at follow-up. METHODS: This was a cross-sectional cohort study of PT-VLBW infants at 1, 2 and 3yrs of age (40/cohort)...

BACKGROUND: Fetal growth restriction is a risk factor for adult cardiovascular disease. Intra-placental gene transfer of human insulin-like growth factor-1 corrects birth weight in our mouse model of fetal growth restriction. This study addresses long term effects of fetal growth restriction on cardiac function and the potential preventive effect of insulin-like growth factor-1. STUDY DESIGN: Laparotomy was performed on pregnant C57BL/6J mice at embryonic day 18 and pups were divided into 3 groups: Sham operated; fetal growth restriction (induced by mesenteric uterine artery ligation); treatment (intra-placental injection of insulin-like growth factor-1 after uterine artery ligation)...
