L K Schüller, I Michaelis, W Heuwieser
The objective of this study was to investigate the impact of heat stress on the expression of estrus signs and follicular diameter at the day of estrus in dairy cows under farm conditions. Cows reported in estrus (i.e., by an automated activity monitoring system or by the herd manager) were examined by a veterinarian. Uterine contractility and the largest diameter of all ovarian structures was determined by transrectal palpation and ultrasonography, respectively. The amount of estrus discharge, mounting traces and the color of the vaginal mucosa were determined in an external examination and scored on 3-point scales...

Erectile dysfunction (ED) affects ∼30% of all men above the age of 40 years and its prevalence steadily increases with age. Current nonsurgical treatment options, including phosphodiesterase type 5 inhibitors (PDE5I), provide temporary relief but have failed to provide a permanent improvement of the condition. Low-intensity extracorporeal shockwave therapy (Li-ESWT) is noninvasive and uses acoustic waves, which can pass through tissue and be focussed to target specific areas or organs to induce the desired effects...

Min-Ho Lee, Ki-Man Lee, Eun-Hee Kim
PURPOSE: In the last decade, new types of "bystander effect" have been suggested by multiple research groups and have been challenged by others. In this study, we explored a new type of bystander effect, which has been defined in previous studies as the enhancement of the survival of high-dose targeted cells due to the penumbra-dose exposed neighbor cells. Intensity modulated radiation therapy, which is the most widely used treatment modality, generates local regions of gradient doses between targeted and shielded cells throughout the treatment volume; therefore, we were urged to ascertain whether the new type of effect is real and to suggest a revised treatment planning...

Polyphenols such as apigenin, kaempferol or resveratrol are typically found in plants, including fruits, vegetables, herbs and spices, which have a wide range of biological functions such as antioxidative, anti-inflammatory, vasodilative, anticoagulative and proapoptotic. Discovering such multifunctional compounds in widely consumed plant-based products - ones that both inhibit the release of TNF-α from tissue macrophages and at the same time enhance the secretion of IL-10 - would be an important signpost in the quest for effective pharmacological treatment of numerous diseases that have an inflammatory etiology...

Rhenium nanoparticles (ReNPs) supported on ordered mesoporous carbon (OMC) as a catalyst (Re/OMC) through a solvent-evaporation induced self-assembly (ELSA) method were prepared. The synthesized heterogonous catalyst was fully characterized using X-ray diffraction, field emission transmission electron microscopy, N2 sorption, metal dispersion, thermogravimetric analysis, Raman, Fourier-transform infrared, and X-ray photon spectroscopies. In addition, the catalyst was applied to reduce the aromatic nitro compounds (ANCs) for the first time in aqueous media and the reactions were monitored by following the intensity changes in the UV-vis absorption spectra with respect to time...

REVIEW
Gilda M Kalinec, Gwen Lomberk, Raul A Urrutia, Federico Kalinec
A significant number of studies support the idea that inflammatory responses are intimately associated with drug-, noise- and age-related hearing loss (DRHL, NRHL and ARHL). Consequently, several clinical strategies aimed at reducing auditory dysfunction by preventing inflammation are currently under intense scrutiny. Inflammation, however, is a normal adaptive response aimed at restoring tissue functionality and homeostasis after infection, tissue injury and even stress under sterile conditions, and suppressing it could have unintended negative consequences...

OBJECTIVE: Restless legs syndrome (RLS) is a neurological sensorimotor disorder characterized by uncomfortable sensations in the legs. RLS often occurs as a comorbid condition. Besides an increased risk of iron deficiency, blood donors are considered to be generally healthy. Blood donors are therefore an ideal population for studying factors associated with RLS occurrence, herein the role of iron. It is suggested that RLS is linked to sex, age, low socioeconomic status, unhealthy lifestyle, and iron deficiency...

Fluidized-bed Fenton coupled with ceramic membrane separation to treat the flax secondary effluent was investigated. The operating variables, including initial pH, dosage of H2O2 and Fe(0), air flow rate, TMP and pore size, were optimized. The distributions of DOMs in the treatment process were analyzed. Under the optimum condition (600mgL(-1)H2O2, 1.4gL(-1) Fe(0), pH=3, 300Lh(-1) air flow rate and 15psi TMP), the highest TOC and color removal efficiencies were 84% and 94% in the coupled reactor with 100nm ceramic membrane, reducing 39% of total iron with similar removal efficiency compared with Fluidized-bed Fenton...

BACKGROUND: Endothelial dysfunction links thrombotic microangiopathy to steroid-refractory graft-versus-host disease (GVHD) after allogeneic stem-cell transplantation. We aimed to assess if the simple formula-lactate dehydrogenase (U/L) × creatinine (mg/dL)/thrombocytes (10(9) cells per L)-termed the Endothelial Activation and Stress Index (EASIX), might be valuable for the prediction of death in patients with acute GVHD after allogeneic stem-cell transplantation. METHODS: For this retrospective analysis, we analysed a training cohort (in Germany) and three validation cohorts (in Germany and the USA) of patients with acute GVHD who had received consecutive allogeneic stem-cell transplantation...

BACKGROUND: Complicated diverticulitis (CD) is a common problem for surgeons. In treating it, as a general principle, every verified source of infection should be controlled. Supplementary antimicrobial management involves a delicate balance of optimizing empirical therapy while reducing unnecessary antibiotic use. The necessity to know the most frequent infecting pathogens and their spectra of resistance is becoming pivotal. The aim of this study was to determine the microbiologic profile of complicated intra-abdominal infections (IAIs) secondary to CD, to analyze the role of empirical antimicrobial therapy, and to describe the clinical aspects of CD worldwide...

Dendritic cells (DCs) orchestrate immune responses after allogeneic hematopoietic cell transplantation (HCT). We studied the association of donor myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) recovery in the landmark analysis of umbilical cord blood (UCB) and matched related donor (RD) HCT. Eighty patients (42 UCB and 38 RD recipients) with a day 100 (D+100) blood sample were included in the analysis. Median age was 51 years (20-71). Most patients had acute leukemia (50%) or lymphoma (23%) and received reduced-intensity conditioning (75%)...

Lulu Wang, Yongchun Zhao, Junying Zhang
Photocatalytic oxidation is an attractive method for Hg-rich flue gas treatment. In the present study, a novel cerium-based TiO2 nanofibers was prepared and selected as the catalyst to remove mercury in flue gas. Accordingly, physical/chemical properties of those nanofibers were clarified. The effects of some important parameters, such as calcination temperature, cerium dopant content and different illumination conditions on the removal of Hg(0) using the photocatalysis process were investigated. In addition, the removal mechanism of Hg(0) over cerium-based TiO2 nanofibers focused on UV irradiation was proposed...

Menopause, the permanent cessation of ovulation, occurs in humans well before the end of the expected lifespan, leading to an extensive post-reproductive period which remains a puzzle for evolutionary biologists. All human populations display this particularity; thus, it is difficult to empirically evaluate the conditions for its emergence. In this study, we used artificial neural networks to model the emergence and evolution of allocation decisions related to reproduction in simulated populations. When allocation decisions were allowed to freely evolve, both menopause and extensive post-reproductive life-span emerged under some ecological conditions...

BACKGROUND: Although breastfeeding is expected to reduce the incidence of diabetes in women with gestational diabetes, the effect has not been clearly confirmed. We examined whether or not high-intensity breastfeeding reduces the incidence of abnormal glucose tolerance and investigated the effect of high-intensity breastfeeding on insulin resistance during the first year postpartum in Japanese women with current gestational diabetes. METHODS: In this retrospective study, we included women with gestational diabetes who underwent postpartum 75 g oral glucose tolerance test during the first year (12-14 months) postpartum from 2009 to 2011 at a single tertiary perinatal care center in Japan...
