Overview on Spermatogenesis and Sperm structure of Hexapoda
submitted by 14 minutes ago - Topic: Biology
The main characteristics of the sperm structure of Hexapoda are reported in the review. Data are dealing with the process of spermatogenesis, including the aberrant models giving rise to a reduced number of sperm cells. The sperm heteromorphism and the giant sperm exceeding the usual sperm size for length and width are considered. The characteristics of several components of a typical insect sp...



Tracing and 3-dimensional representation of the primary afferents from the moth ear
submitted by 14 minutes ago - Topic: Biology
Heliothine moths perceive acoustic information via two auditory sensory neurons only. Previous cobalt staining experiments have described the projection pattern of the two auditory neurons, called the A1 and the A2 cell, plus one additional neuron, the so-called B cell, up to the prothorax. We have obtained new and improved data about the projection pattern of the three sensory afferents by mea...

The critical role of myeloid-derived suppressor cells and FXR activation in immune-mediated liver injury
submitted by 14 minutes ago - Topic: Health
The immunobiology of FXR has attracted significant attention in immune regulation and innate immunity. We have studied the mechanism of action of FXR activation on two models of acute hepatitis, inflammation mediated by Con A and α-GalCer and focused on the interactions of FXR activation and expression of PIR-B, both in vivo and in vitro using luciferase reporter and CHIP assays. In addition...

Effects of radio-tag characteristics and sample size on estimates of apparent survival
submitted by 14 minutes ago - Topic: Biology
Radio-tracking is increasingly used to assess key characteristics of population dynamics. Since in many species re-encounter rates are frequently below 1.0 and vary with time and/or life-history stages, known-fate approaches to analyses may not apply. Cormack-Jolly-Seber (CJS) models estimate apparent survival on the basis of individual encounter histories. These models allow for complex re-enc...

Tri-axial accelerometers quantify behaviour in the Eurasian badger (Meles meles): towards an automated interpretation of field data
submitted by 14 minutes ago - Topic: Biology
The popularity of tri-axial accelerometer data loggers to quantify animal activity through the analysis of signature traces is increasing. However, there is no consensus on how to process the large data sets that these devices generate when recording at the necessary high sample rates. In addition, there have been few attempts to validate accelerometer traces with specific behaviours in non-dom...



Land-Use Threats and Protected Areas: A Scenario-Based, Landscape Level Approach
submitted by 14 minutes ago - Topic: Geography
Anthropogenic land use will likely present a greater challenge to biodiversity than climate change this century in the Pacific Northwest, USA. Even if species are equipped with the adaptive capacity to migrate in the face of a changing climate, they will likely encounter a human-dominated landscape as a major dispersal obstacle. Our goal was to identify, at the ecoregion-level, protected areas ...

Landscape Aesthetics and the Scenic Drivers of Amenity Migration in the New West: Naturalness, Visual Scale, and Complexity
submitted by 14 minutes ago - Topic: Geography
Values associated with scenic beauty are common “pull factors” for amenity migrants, however the specific landscape features that attract amenity migration are poorly understood. In this study we focused on three visual quality metrics of the intermountain West (USA), with the objective of exploring the relationship between the location of exurban homes and aesthetic landscape preference, a...


Redistribution of heart failure as the cause of death: the Atherosclerosis Risk in Communities Study
submitted by 15 minutes ago - Topic: Health
Heart failure is sometimes incorrectly listed as the underlying cause of death (UCD) on death certificates, thus compromising the accuracy and comparability of mortality statistics. Statistical redistribution of the UCD has been used to examine the effect of misclassification of the UCD attributed to heart failure, but sex- and race-specific redistribution of deaths on coronary heart disease (C...

The computed tomography during hepatic arteriography pattern may predict hepatocellular carcinoma recurrence following transarterial chemoembolization
submitted by 16 minutes ago - Topic: Health
This study aimed to determine the role of morphological patterns seen on imaging in predicting hepatocellular carcinoma recurrence following transarterial chemoembolization therapy. Forty-seven patients from a single center who underwent transarterial chemoembolization to treat unresectable hepatocellular carcinomas between January 2011 and June 2012 were included in this study. We investigated...


Renal function status in liver transplant patients in the first month post-transplant is associated with progressive chronic kidney disease
submitted by 16 minutes ago - Topic: Health
Renal dysfunction is a common complication of liver transplantation (LT), related to hepatorenal syndrome with end-stage liver disease or calcineurin-inhibitor (CNI) nephrotoxicity. Chronic kidney disease (CKD) is also a common problem in long-term survivors post-LT. This study was done to investigate the association between renal functional status soon after LT and the development of CKD. We r...

Low Expression of BARX2 in Human Primary Hepatocellular Carcinoma Correlates with Metastasis and Predicts Poor Prognosis
submitted by 17 minutes ago - Topic: Health
The homeobox gene Barx2 was recently identified as a regulator of ovarian and breast cancer; however, the expression level of BARX2 and its significance in hepatocellular carcinoma (HCC) remain unknown. Protein and mRNA expression levels of Barx2 were examined using Western blotting and real-time PCR respectively, in paired HCC tissue and matched adjacent noncancerous tissue from 12 patients. T...


Potential impact of joint association of alanine aminotransferase and gamma- glutamyltransferase on insulin resistance in Japan: the Toranomon Hospital Health Management Center Study 19 (TOPICS 19)
submitted by 17 minutes ago - Topic: Health
To investigate the potential impact of joint association of alanine aminotransferase(ALT) and gamma-glutamyltransferase(GGT) on insulin resistance and beta–cell dysfunction in Japanese healthy individuals with normal range of liver enzymes. This study included 1010 individuals (545 men and 465 women) aged 20-89 years who underwent an oral glucose tolerance test for health screening. Participa...

Bimodal Peaks of Liver Stiffness in a Case of Drug-Induced Liver Injury
submitted by 17 minutes ago - Topic: Health
A 69-year-old male visited our facility for a further evaluation of icterus. He complained of general fatigue and presented with elevation of liver enzymes without any cause of liver injury. We diagnosed him with hepatocellular drug-induced liver injury (DILI). Liver stiffness, which was evaluated according to the shear wave velocity (SWV) using virtual touch tissue quantification, was serially...

Red cell distribution width as a potential index to assess the severity of hepatitis B virus-related liver diseases
submitted by 17 minutes ago - Topic: Health
To investigate the association between red cell distribution width (RDW) and the severity of hepatitis B virus (HBV)-related liver diseases. Sixty-nine patients with chronic hepatitis B (CHB) and 61 patients with HBV-related liver cirrhosis were enrolled in the present study. Forty-one healthy individuals were included as control. Hematological parameters, HBeAg status, HBV DNA levels and liver...

Fourier Analysis of Quasi-phase Matching Devices for WDM
submitted by 19 minutes ago - Topic: Biology
Since the introduction of wavelength division multiplexing system, the capacity of the optical fibers to carry data was immensely increased. High speed and efficient data transfer thence made possible. Further, the use of quasi-phase matching devices enables us to achieve wavelength division multiplexing with negligible inter symbol interference and cross talk. In this study, we present a theor...
