—Temporal noise sets the fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is primarily due to the photodetector shot noise and the output amplifier thermal and 1 noise. CMOS image sensors suffer from higher noise than CCDs due to the additional pixel and column(More)
c-Jun N-terminal kinase-3 (JNK3), the only neural-specific isoform, may play an important role in excitotoxicity and neuronal injury. To analyze the variation of JNK3 activation, levels of phospho-JNK3 were measured at various time points of ischemia and selected time points of reperfusion, respectively. Our study illustrated that JNK3 was rapidly activated(More)
G protein-coupled receptor 43 (GPR43) has been identified as a receptor for short-chain fatty acids that include acetate and propionate. A potential involvement of GPR43 in immune and inflammatory response has been previously suggested because its expression is highly enriched in immune cells. GPR43 is also expressed in a number of other tissues including(More)
Our previous studies have shown that microRNA-383 (miR-383) expression is downregulated in the testes of infertile men with maturation arrest (MA). Abnormal testicular miR-383 expression may potentiate the connections between male infertility and testicular germ cell tumors. However, the mechanisms underlying the targeting and functions of miR-383 during(More)
BACKGROUND AND PURPOSE The present studies examined the hypothesis that the distribution of cerebral injury after a focal ischemic insult is associated with the regional distribution of nitric oxide synthase (NOS) activity. METHODS Based on previous studies that certain anatomically well-defined areas are prone to become either core or penumbra after(More)
The biological effects of the melanin-concentrating hormone (MCH) are mediated by the melanin concentrating hormone receptor 1 (MCHR1) in mice. This receptor is enriched in brain areas that are involved in the modulation of mood and affect, suggesting that MCH-dependent signaling may influence neurobiological mechanisms underlying fear and anxiety(More)
BACKGROUND MicroRNAs (miRNAs), a class of small non-coding RNA molecules, are indicated to play essential roles in spermatogenesis. However, little is known about the expression patterns or function of miRNAs in human testes involved in infertility. METHODS In this study, the miRNA expression profiles of testes of patients with non-obstructive azoospermia(More)
Using an 11.7-Tesla magnetic resonance imaging (MRI) scanner in 10-d-old rat pups we report on the evolution of injury over 28 d in a model of neonatal stroke (transient filament middle cerebral artery occlusion, tfMCAO) and a model of hypoxic-ischemic injury (Rice-Vannucci model, RVM). In both models, diffusion-weighted imaging (DWI) was more sensitive in(More)
Kainate receptor glutamate receptor 6 (GluR6) binds to the postsynaptic density protein 95 (PSD-95), which in turn anchors mixed lineage kinase 3 (MLK3) via SH3 domain in rat brain tissue. MLK3 subsequently activates c-Jun NH(2)-terminal kinase (JNK) via MAP kinase kinases (MKKs). We investigated the association of PSD-95 with GluR6 and MLK3, MLK3(More)
BACKGROUND The aim of this study was to examine BRF2 expression in patients with non-small cell lung cancer (NSCLC) and explore the relationship of BRF2 protein with clinicopathologic factors, tumor angiogenesis and prognosis. METHODS Both BRF2 protein and intratumoral microvessels were examined by immunohistochemical staining in 107 non-small cell lung(More)
