This study investigated the mechanisms responsible for the neuroprotective effect of sildenafil citrate (SFC) on ischemia-reperfusion spinal cord (SC) injuries. Balloon occlusion of the thoracic aorta was used to induce SC ischemia. The animals (n=30) were separated into three groups: sham, SC injury with saline, and SC injury with 5mg/kg i.p. SFC treatment (SFC). The Basso, Beattie, and Bresnahan (BBB) score was determined to assess neurological function at different time intervals after reperfusion. After 48h, histopathology of the SC was assessed by triphenyltetrazolium chloride (TTC) and Nissl staining...

Phenolic compounds are among the endocrine disruptors which are widely used in daily life products. Studies in laboratory animals showed reproductive and developmental effects. In spite of widespread exposure to phenols, only few studies examined their effects on human development. This study was designed to investigate the relationship between antenatal phenol exposure and birth outcomes in a Chinese obstetric population. Four hundred ninety-six mother-infant pairs recruited from the Laizhou Wan prospective birth cohort in northern China between 2010 and 2013 were included in the study...

Cardiovascular complications induced by high fat are one of the most challenging health problems presently. Oxidative stress, inflammation and fibrosis are major components included in the pathology of diabetic cardiomyopathy. Nuclear factor erythroid 2-related factor 2 (Nrf2) has been reported as an essential therapeutic target in various diseases for its induction of anti-oxidant enzymes, and other protective enzymes. Additionally, a number of Nrf2 activators showed strong anti-inflammatory properties. In the study, we calculated the Nrf2-dependent anti-oxidant, anti-inflammatory and anti-fibrosis effects of chrysophanol in high fat diet-induced diabetic heart injury...

The effects of Wnt signaling modifiers on cell proliferation, seem to be cell specific. Enhancing the proliferation of subventricular zone (SVZ) progenitors has been in the focus of research in recent years. Here we investigate the effect of CHIR99021, a Glycogen Synthase Kinase 3 (GSk-3) inhibitor, on SVZ progenitor's proliferation both in vivo and in vitro. Neural stem cells were extracted from the adult C57bl/6 by mincing and trypsin treatment followed by culturing in specific medium. Sphere cells formed within about 7-10days and were characterized by immunostaining...

BACKGROUND: With the exception of liver transplantation, there is no cure for hemophilia, which is currently managed by preemptive replacement therapy. Liver-derived stem cells are in clinical development for inborn and acquired liver diseases and could represent a curative treatment for hemophilia A. The liver is a major factor VIII (FVIII) synthesis site, and mesenchymal stem cells have been shown to control joint bleeding in animal models of hemophilia. Adult-derived human liver stem cells (ADHLSCs) have mesenchymal characteristics and have been shown able to engraft in and repopulate both animal and human livers...

<br>Background: Studies examining the ability of estrogen replacement therapy (ERT) to enhance memory in women, and in animal models, have not produced consistent results. However, studies examining the effects of activity and exposure to novel environments consistently find enhancement of memory. METHODS: An animal model of reproductive aging was used to determine if estradiol (E2) replacement, activity, and/or exposure to an enriched environment could act synergistically to improve memory, and neural correlates of memory...

Prevention of deterioration of brain function over time is important in the long-term management of chronic brain disorders such as dementia, schizophrenia, and mood disorders. Although the possibility of neurogenesis in the adult human brain is attractive, and there are psychiatric drugs proven to be effective inducers of neurogenesis in animals, we have yet to see their utility in clinical practice. The terms neurodegeneration and neuroregeneration are often used in a nonspecific manner. Neuroregeneration may mean neurogenesis, dendritogenesis, spinogenesis, or axonogenesis...

Lanthanum (La) modified bentonite (LMB) is one of the available mitigating agents used for the reduction of the phosphorus (P) recycling in eutrophic lakes. The potential toxicity of the La from LMB to aquatic organisms is a matter of concern. In this study the accumulation of La was investigated in the macrophyte Elodea nuttallii, in chironomid larvae and in several fish species during periods up to five years following in situ LMB applications. The application of LMB increased the La concentration of exposed plants and animals...

Leishmaniasis is a term referring to a range of clinical conditions caused by protozoan parasites of the genus Leishmania, Trypanosomatidae family, Kinetoplastida order that is transmitted by the bite of certain species of mosquitoes Phlebotominae subfamily. These parasites infect hosts wild and domestic mammals, considered as natural reservoirs and can also infect humans. Leishmania are obligate intramacrophage protozoa that have exclusively intracellular life style. This suggests that the amastigotes possess mechanisms to avoid killing by host cells...

REVIEW
Esteban Martínez-García, Víctor de Lorenzo
The interest of the genus Pseudomonas largely relies on the virulence of some of its species for plants and animals (including humans). Yet, pathogenic features of some isolates coexist with others often present in environmental variants that promote plant growth and degrade chemical pollutants. Many of these traits can be traced to the intrinsic properties of the genomic chassis of this genus along with distinct genetic parts and devices. With the tools of Synthetic Biology these can be enhanced and/or repurposed for the sake of biological control, environmental remediation and whole-cell biocatalysis...

A new low-energy gelled emulsion containing algae oil was developed as animal fat replacer. Its stability was evaluated under different storage conditions: 4V (4°C/vacuum), 4NV (4°C/no vacuum), 25V (25°C/vacuum) and 25NV (25°C/no vacuum). According to moisture, hardness, color and lipid oxidation data, 4°C under vacuum (4V) was selected as the best condition. Once the gelled emulsion was characterized, its effectiveness as fat analogue was demonstrated in beef patties. Reformulated patties were produced with 100% of animal fat replacement and compared to conventional patties (9%fat)...

In the European Union, slaughter without stunning is allowed for religious slaughter to obtain halal and kosher meat. Especially in the case of Jewish slaughtering, cuts which are not deemed as kosher are sold to regular market without any specific labelling. This survey, conducted in Tuscany in 2016, aimed to quantify the carcasses rejected in relation to the type of religious slaughter. 656 bovines were slaughtered without stunning: 538 (82%) for halal and 118 (18%) for kosher. All carcasses slaughtered by the Islamic procedure (dhabiha) were considered halal, while 77...
