Acquisition of cell identity in plants relies strongly on positional information, hence cell-cell communication and inductive signalling are instrumental for developmental patterning. During Arabidopsis embryogenesis, an extra-embryonic cell is specified to become the founder cell of the primary root meristem, hypophysis, in response to signals from(More)
Optimum coherent receivers for CPM-signals have in general a high degree of complexity. Especially for the most interesting schemes that offer significant power and bandwidth efficiency with smoothed frequency pulses, o r that implement a n additional convolu-tional code, the number of parallel filters at the receiver input, and the number of memory-states(More)
Tightly controlled gene expression is a hallmark of multicellular development and is accomplished by transcription factors (TFs) and microRNAs (miRNAs). Although many studies have focused on identifying downstream targets of these molecules, less is known about the factors that regulate their differential expression. We used data from high spatial(More)
For smart grid applications, power line communications (PLC) have become a promising candidate to support some emerging services. Although it may employ frequencies above 500 kHz to guarantee reliable performance and fast response, potential interferences between such PLC access system and medium wave (MW)/short wave (SW) broadcast radios may be caused.(More)
The sodium-vitamin C co-transporter SVCT2 is primarily responsible for the accumulation of the important antioxidant ascorbate into brain cells. In vitro studies have demonstrated strong expression of this transporter in cultured astrocytes, whereas in situ hybridization analysis has so far detected SVCT2 only in neurons. In the present study, we examined(More)
Fibroblast growth factor 1 (FGF1) is an autocrine/paracrine regulator whose binding to heparan sulphate proteoglycans effectively precludes its circulation. Although FGF1 is known as a mitogenic factor, FGF1 knockout mice develop insulin resistance when stressed by a high-fat diet, suggesting a potential role in nutrient homeostasis. Here we show that(More)
The prevalence of obesity is a growing health problem. Obesity is strongly associated with several comorbidities, such as non-alcoholic fatty liver disease, certain cancers, insulin resistance, and type 2 diabetes, which all reduce life expectancy and life quality. Several drugs have been put forward in order to treat these diseases, but many of them have(More)
AIMS Electroacupuncture (EA) is one of the safety and effective therapies for improving neurological and sensorimotor impairment via blockade of inappropriate inflammatory responses. However, the mechanisms of anti-inflammation involved is far from been fully elucidated. MAIN METHODS Focal cerebral ischemic stroke was administered by the middle cerebral(More)
Abshnct-By means of a signal representation in a signal space spanned by a few time-limited exponential basis-functions, and data-aided maximum-liltelhood techniques, novel methods for the joint and nosioint estimation of carrier-phase and symbol-W i g for general coherent CPM receivers am! pmposed. The estimators are quite simple, especially in obtaining(More)
Ischemic stroke, the second leading cause of death worldwide, leads to excessive glutamate release, over-activation of N-methyl-D-aspartate receptor (NMDAR), and massive influx of calcium (Ca2+), which may activate calpain and caspase-3, resulting in cellular damage and death. Memantine is an uncompetitive NMDAR antagonist with low-affinity/fast off-rate.(More)
