The role of Na+ in hypoxic injury was evaluated by a time-course analysis of damage in isolated livers perfused with N2-saturated buffer containing standard (143 mM) or low (25 mM) Na+ levels. Trypan blue uptake was used to detect non-viable cells. Under hypoxia with standard-Na+, trypan blue uptake began at the border between pericentral areas and periportal regions and increased in the latter zone; using a low-Na+ buffer, no trypan blue zonation occurred but a homogenous distribution of dye was found associated with sinusoidal endothelial cell (SEC) staining...

The present study was aimed at investigating whether human Periodontal Ligament Stem Cells (hPDLSCs) were capable of sensing and reacting to lipopolysaccharide from Porphyromonas gingivalis (LPS-G) which is widely recognized as a major pathogen in the development and progression of periodontitis. At this purpose hPDLCs were stimulated with 5 μg/mL LPS-G various times and the expression of toll-like receptor 4 (TLR4) was evaluated. Toll-like receptors (TLRs) play an essential role in innate immune signaling in response to microbial infections, and in particular TLR4, type-I transmembrane proteins, has been shown recognizing LPS-G...

Multiple factors have been considered to play a role in the development of benign prostatic hyperplasia (BPH), including chronic inflammation, hormones, and epithelial-mesenchymal transition (EMT). Inflammation is regarded as one of the potential inducers of EMT. However, the mechanisms, modulating pro-inflammatory factors (IL-6 and TGF-β1) induce EMT features, have not yet been studied in BPH. In this study, we investigated whether DNA methyltransferases1 (DNMT1) could regulate IL-6 and TGF-β1 induce EMT...

We previously developed a novel method for gene transfer, which combined a non-viral gene expression vector with transcutaneous in vivo electroporation. We applied this method to transfer the bone morphogenetic protein (BMP) gene and induce ectopic bone formation in rat skeletal muscles. At present, it remains unclear which types of cells can differentiate into osteogenic cells after BMP gene transfer by in vivo electroporation. Two types of stem cells in skeletal muscle can differentiate into osteogenic cells: muscle-derived stem cells, and bone marrow-derived stem cells in the blood...

Fluorescence in situ hybridization (FISH) is an essential tool for genetic diagnosis in daily pathological work. Almost full automation of FISH can be achieved with the recently released automated SureFISH platform (Dako Omnis, Agilent Technologies, Santa Clara, CA, USA). Its utility has been reported in HER2 amplification of breast and gastric carcinoma and ALK-rearranged lung cancer. Here, we examined the utility of automated SureFISH for the identification of rearrangement signals in translocation-related sarcomas (TRSs), including 11 EWSR1-rearranged and 10 synovial sarcoma cases, compared with non-automated conventional FISH using the same specimens...

Introduction Maternal exposure to tobacco smoke is associated with shortened breastfeeding duration, but few studies have examined the effects on breastfeeding outcomes of low level exposures to other toxic chemicals. Moreover, it is unclear if passive smoking is associated with duration of breastfeeding. Our objective was therefore to examine the effect of low-level prenatal exposures to common environmental toxins (tobacco smoke, lead, and phthalates) on breastfeeding exclusivity and duration. Methods We conducted an analysis of data from the Health Outcomes and Measures of the Environment (HOME) Study...

To gain more insight into central hearing loss, we investigated the relationship between cortical thickness and surface area, speech-relevant resting state EEG power, and above-threshold auditory measures in older adults and younger controls. Twenty-three older adults and 13 younger controls were tested with an adaptive auditory test battery to measure not only traditional pure-tone thresholds, but also above individual thresholds of temporal and spectral processing. The participants' speech recognition in noise (SiN) was evaluated, and a T1-weighted MRI image obtained for each participant...

Mass cytometry time-of-flight (CyTOF) empowers us to understand acute myeloid leukemia (AML) biology at the single-cell level. This technology, combined with advanced data-analysis methods, enables identification and characterization of the rare AML stem/progenitor cells that play key roles in drug resistance and AML relapse. Here we provide a protocol for AML sample preparation for CyTOF and keynotes emphasizing critical steps in and troubleshooting strategies for this procedure.

Protein hydrolysate was prepared from Acetes indicus which is a major bycatch among non-penaeid prawn landings of India. Hydrolysis conditions (enzyme to substrate ratio and time) for preparing protein hydrolysates using alcalase enzyme were optimized by response surface methodology using central composite design. The optimum conditions for enzyme-substrate ratio (mL/100 g) of 1.57, 1.69, 1.60, 1.56, and 1.50 and for hydrolysis time of 97.18, 96.5, 98.15 min, 102.48, and 88.44 min were established for attaining maximum yield, degree of hydrolysis, 2,2-diphenyl-1-picrylhydrazyl, angiotensin I-converting enzyme-inhibiting activity, and metal-chelating activity, respectively...

We carried out phylogenetic analyses of the relationships between Dicrocoelium chinensis populations in Japan and China using molecular markers. One hundred nine lancet flukes collected from Japan and China were identified as D. chinensis based on their testis orientation and the nucleotide sequences of their ribosomal ITS2. These flukes were analyzed phylogenetically using mitochondrial nad1 gene sequences. An analysis of molecular variance found that the percentage of variation between the countries was extremely high, indicating that the D...

We assessed the US state-level budget and societal impact of implementing two child abuse and neglect (CAN) primary prevention programs. CAN cost estimates and data from two prevention programs (Child-Parent Centers and Nurse-Family Partnership) were combined with current population, cost, and CAN incidence data by US state. A cost-benefit mathematical model for each program by US state compared program costs with the future monetary value of benefits from reduced CAN. The models used a lifetime time horizon from government payer and societal perspectives...

Extreme hot weather events are likely to increase under future climate change, and it is exacerbated in urban areas due to the complex urban settings. It causes excess mortality due to prolonged exposure to such extreme heat. However, there is lack of universal definition of prolonged heat or heat wave, which leads to inadequacies of associated risk preparedness. Previous studies focused on estimating temperature-mortality relationship based on temperature thresholds for assessing heat-related health risks but only several studies investigated the association between types of prolonged heat and excess mortality...

Retinoic acid (RA) is of major importance during vertebrate embryonic development and its levels need to be strictly regulated otherwise congenital malformations will develop. Through the action of specific nuclear receptors, named RAR/RXR, RA regulates the expression of genes that eventually influence proliferation and tissue patterning. RA has been described as crucial for different stages of mammalian lung morphogenesis, and as part of a complex molecular network that contributes to precise organogenesis; nonetheless, nothing is known about its role in avian lung development...

Existing literature suggests that use of telemedicine during postoperative appointments can increase access to care and is valued by patients and providers alike. While research examining the clinical equivalency of telemedicine visits for postoperative care has been growing, few studies have reported on telemedicine follow-up after neurosurgery. This study examined if a videoconferencing visit could substitute for an in-person clinic visit for elective neurosurgical cases in the USA. This was a single-center prospective study of patients who underwent elective neurosurgical procedures (aneurysm clipping, resection of cavernous angiomas, resection of arterial venous malformation, microvascular decompression for trigeminal neuralgia and hemifacial spasm, and certain benign brain tumors) and were offered telemedicine follow-up care by an allied health professional during the first 90 days after neurosurgery...

With increasing cascading effects of climate change on the marine environment, as well as pollution and anthropogenic utilization of the seafloor, there is increasing interest in tracking changes to benthic communities. Macrofaunal surveys are traditionally conducted as part of pre-incident environmental assessment studies and post-incident monitoring studies when there is a potential impact to the seafloor. These surveys usually characterize the structure and/or spatiotemporal distribution of macrofaunal assemblages collected with sediment cores; however, many different sampling protocols have been used...

Detection of soil element deficiencies is time consuming, requiring a major commitment for field work and analysis. Bees concentrate some elements in their honey which could allow soil element concentrations to be predicted without having to take large numbers of soil samples. We measured 14 element concentrations in soil, sunflower, acacia flower and honey samples from two different regions of Hungary. Across sites, the elements with significant correlation coefficients between honey and soil concentrations, in descending order of probability, were Cu > Ba >Sr = Ni > Zn > Mn = Pb >As...
