New mite species from a Caribbean mesophotic coral ecosystem named after J.Lo

New mite species from a Caribbean mesophotic coral ecosystem named after J.Lo
2014-07-15
(Press-News.org) During a recent survey of organisms collected from Bajo de Sico, a mesophotic coral reef ecosystem in Mona Passage off Puerto Rico, one pontarachnid mite species new to science was discovered. The new species was named after the famous Puerto Rican singer Jennifer Lopez. The study was published in the open access journal ZooKeys.

"The reason behind the unusual choice of name for the new species", explains the lead author Vladimir Pešić, Department of Biology, University of Montenegro, "is that J.Lo's songs and videos kept the team in a continuous good mood when writing the manuscript and watching World Cup Soccer 2014."

Pontarachnid mites represent widely distributed but still unstudied group of marine animals. Nothing is known about the life cycle of these animals. The new mite species was collected from nearly 70 m depth, the greatest depth from which Pontarachnid mites have been found until now.

Mesophotic coral ecosystems (MCEs), like Bajo de Sico where the new species was found are light-dependent habitats dominated by macroalgae, sponges and scleractinian corals and are found on the insular and continental slopes of Caribbean islands between 30 and 100 m. Even at the lower depth range (70-100 m), there is enough light for photosynthesis to take place enhancing the growth of several scleractinian coral species and algae.

The MCEs of Puerto Rico represent a potential biodiversity hotspot for marine arthropods.

Hidden variations in neuronal networks may explain differences in brain injury outcomes

2014-07-15
ATLANTA–A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can account for whether animals are behaviorally susceptible to brain injury. These results could have implications for the treatment of brain trauma. People vary in their responses to stroke and trauma, which impedes the ability of physicians to predict patient outcomes. Damage to the brain and nervous system can lead to severe disabilities, including epilepsy and cognitive impairment. If doctors could ...

To accept or not accept -- Patients want a say in liver transplant decisions
2014-07-15
A novel study reveals that more than half of liver transplant patients want to be informed of donor risk at the time a liver is offered for transplantation. Nearly 80% of those patients want to be involved in the decision of whether or not to accept the organ according to findings published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society. There is a shortage of available donor organs, which leaves many on the liver transplant waiting list. Currently, there are more than ...

Cardiac patients underserved globally due to lack of rehab programs: York University researcher

2014-07-15
TORONTO, July 15, 2014 — Rehabilitation programs must become an integral part of cardiac care to significantly reduce the burden of living with heart disease, one of the most common chronic diseases and causes of death globally, according to York University Professor Sherry Grace. "Cardiac rehabilitation is a cost-effective program offering heart patients exercise, education and risk reduction," says Grace, noting that participation results in 25 per cent less death, lower re-hospitalization rates and better quality of life. Despite these benefits, cardiac rehabilitation ...

Neuropeptide Y protects cerebral cortical neurons

Neuropeptide Y protects cerebral cortical neurons
2014-07-15
Neuropeptide Y exhibits neuroprotective effects. Whether the neuroprotective effects are mediated by the pathways including regulating the immunological activity of reactive microglia and reducing cytokines remains unclear. Prof. Wenqing Zhao, Graduate School, Heibei Medical University, China and his team confirmed that neuropeptide Y prevented excessive production of interleukin-1β and tumor necrosis factor-α by inhibiting microglial reactivity, reduced N-methyl-D-aspartate current in rat cortical neurons, preventing excitotoxicity, and thereby protecting neurons. ...

Hippocampal neuron-related factor expression and neuronal injury after TBI

Hippocampal neuron-related factor expression and neuronal injury after TBI
2014-07-15
Traumatic brain injury (TBI) causes gene expression changes in different brain regions. Cyclooxygenase-2, glutamate receptor-2, and platelet activating factor receptor expression levels are related to the occurrence and development of TBI. However, the precise relationship between the expression levels of these three factors and neuronal injury after TBI remains poorly understood. Zhiqiang Li, Inner Mongolia Corps Hospital, Chinese People's Armed Police Forces, China performed a study and showed that sequential expression of cyclooxygenase-2, glutamate receptor-2, and platelet ...

Signaling pathway for ginsenoside Rb1 promoting hippocampal neuronal neurite outgrowth

Signaling pathway for ginsenoside Rb1 promoting hippocampal neuronal neurite outgrowth
2014-07-15
The main pathological changes of Alzheimer's disease (AD) include amyloid-beta protein-induced hippocampal neuronal injury and neurite outgrowth impairment. Phosphatidylinositol 3-kinase (PI3K)/Akt pathway and mitogen-activated protein kinase (MAPK) pathway are the important signaling pathways respectively responsible for regulating synaptic plasticity and neuronal survival. In view of the fact that ginsenoside Rb1 exhibits anti-aging and anti-dementia effects, Prof. Qionglan Yuan and her team, Department of Anatomy & Neurobiology, Tongji University School of Medicine, ...

The ADC does not reflect cytotoxic edema on the uninjured side after TBI

The ADC does not reflect cytotoxic edema on the uninjured side after TBI
2014-07-15
It is currently difficult to treat traumatic brain injury (TBI) in the clinic. There are abundant neural network connections and humoral regulation mechanisms between the cerebral hemispheres. Brain tissue on the uninjured side after TBI may also undergo abnormal changes, but these changes remain poorly understood. Hong Lu and her team, Affiliated Haikou Hospital, Xiangya School of Medicine, Central South University, in China performed a study to investigate whether apparent diffusion coefficient (ADC) measurements can reflect cytotoxic edema on the uninjured side using ...

Protective effect of α-synuclein knockdown on dopaminergic neurons

Protective effect of α-synuclein knockdown on dopaminergic neurons
2014-07-15
The over-expression of α-synuclein is a major factor in the death of dopaminergic neurons in a methamphetamine-induced model of Parkinson's disease (PD). Dr. Huijun Wang, School of Basic Medical Sciences, Southern Medical University, China and his team injected α-synuclein-shRNA lentivirus stereotaxically into the right striatum of experimental rats to inhibit α-synuclein mRNA and protein expression. Results showed that after α-synuclein knockdown, the depression manifestations of PD rats were reduced, striatal dopamine and tyrosine hydroxylase levels ...

Shanghai scientists challenge classical phenomenon that water always completely wets water
2014-07-15
The molecular scale behavior of water at a solid/liquid interface holds fundamental significance in a diverse set of technical and scientific contexts, ranging from the efficiency of oil mining to the activity of biological molecules. Recently, it has become recognized that both the physical interactions and the surface morphology have significant impact on the behavior of interfacial water, including the water structures and wetting properties of the surface. In a new review, Chunlei Wang, Yizhou Yang and Haiping Fang of the Shanghai Institute of Applied Physics report ...
