A 6.7–11.2 Gb/s, 2.25 pJ/bit, Single-Loop Referenceless CDR With Multi-Phase, Oversampling PFD in 65-nm CMOS

Park, Kwanseo,Bae, Woorham,Lee, Jinhyung,Hwang, Jeongho,Jeong, Deog-Kyoon IEEE 2018 IEEE journal of solid-state circuits Vol.53 No.10

<P>A single-loop referenceless clock and data recovery (CDR) with a compact frequency acquisition scheme is presented. A bang–bang phase–frequency detector (BBPFD) is proposed that tracks the frequency difference by detecting the drift direction of the non-return to zero bit stream with respect to the multi-phase clock and generates UP/DN output signals accordingly. When frequency locked, the BBPFD is degenerated into the conventional bang–bang phase detector (BBPD). The UP/DN output signals from the BBPFD are thus connected directly to the loop filter, thereby reducing the acquisition time without any loss of cycles. The effect of sampling phase mismatch is analyzed, and the capture range is calculated. In addition, the frequency acquisition time is analytically derived and verified by simulation. The proposed CDR has been implemented in a 65-nm CMOS process and occupies an active area of 0.047 mm<SUP>2</SUP>. The measured capture range is 6.7–11.2 Gb/s, and the frequency acquisition time is less than 2.19 <TEX>$\mu \text{s}$</TEX>. The proposed CDR achieves error-free operation (BER < 10<SUP>−12</SUP>) for PRBS31 pattern and consumes 22.5 mW at 10 Gb/s.</P>

Protective effect of ultrasonication-processed ginseng berry extract on the D-galactosamine/lipopolysaccharide-induced liver injury model in rats

Nam, Yoonjin,Bae, Jinhyung,Jeong, Ji Hoon,Ko, Sung Kwon,Sohn, Uy Dong The Korean Society of Ginseng 2018 Journal of Ginseng Research Vol.42 No.4

Background: Acute hepatic failure is a life-threatening critical condition associated with rapid deterioration of liver function and liver transplantation. Several studies have shown that Panax ginseng Mayer has antidiabetic and hepatoprotective effects. However, the hepatoprotective effect of ginseng berry is still unveiled. In this study, we evaluated the hepatoprotective effects of ultrasonication-processed ginseng berry extract (UGBE) on acute hepatic failure model in rats. Methods: Ginseng berry extract (GBE) was ultrasonically processed. The GBE, silymarin, and UGBE were orally administered to male Sprague-Dawley rats for 4 wk. Twenty-four h after the last administration, rats were challenged with D-galactosamine (D-GalN)/lipopolysaccharide (LPS). Results: After ultrasonication, the component ratio of ginsenosides Rg2, Rg3, Rh1, Rh4, Rk1, Rk3, and F4 in GBE had been elevated. Administration of UGBE significantly increased the survival rate of D-GalN/LPS-challenged rats. Pretreatment with UGBE significantly decreased serum alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels in D-GalN/LPS-challenged rats in a dose-dependent manner. The levels of enzymatic markers for oxidative stress (superoxide dismutase, glutathione peroxidase, catalase, and glutathione) were increased by UGBE treatment in a dose-dependent manner. Tumor necrosis factor alphalevel, inducible nitric oxide synthase activities, and nitric oxide productions were reduced by UGBE treatment. In addition, hemeoxygenase-1 levels in liver were also significantly increased in the UGBE-treated group. The protein expression of toll-like receptor 4 was decreased by UGBE administration. Hematoxylin and eosin staining results also supported the results of this study showing normal appearance of liver histopathology in the UGBE-treated group. Conclusion: UGBE showed a great hepatoprotective effect on D-GalN/LPS-challenged rats via the toll-like receptor 4 signaling pathway.

Neuronal Responses in the Globus Pallidus during Subthalamic Nucleus Electrical Stimulation in Normal and Parkinson's Disease Model Rats

Ryu, Sang Baek,Bae, Eun Kyung,Kim, Jinhyung,Hwang, Yong Sup,Im, Changkyun,Chang, Jin Woo,Shin, Hyung-Cheul,Kim, Kyung Hwan The Korean Society of Pharmacology 2013 The Korean Journal of Physiology & Pharmacology Vol.17 No.4

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been widely used as a treatment for the movement disturbances caused by Parkinson's disease (PD). Despite successful application of DBS, its mechanism of therapeutic effect is not clearly understood. Because PD results from the degeneration of dopamine neurons that affect the basal ganglia (BG) network, investigation of neuronal responses of BG neurons during STN DBS can provide informative insights for the understanding of the mechanism of therapeutic effect. However, it is difficult to observe neuronal activity during DBS because of large stimulation artifacts. Here, we report the observation of neuronal activities of the globus pallidus (GP) in normal and PD model rats during electrical stimulation of the STN. A custom artifact removal technique was devised to enable monitoring of neural activity during stimulation. We investigated how GP neurons responded to STN stimulation at various stimulation frequencies (10, 50, 90 and 130 Hz). It was observed that activities of GP neurons were modulated by stimulation frequency of the STN and significantly inhibited by high frequency stimulation above 50 Hz. These findings suggest that GP neuronal activity is effectively modulated by STN stimulation and strongly dependent on the frequency of stimulation.

The Inhibitory Mechanism of Gentamicin on Electrical Field Stimulation Response in Rat Bladder Smooth Muscle

Min, Chang Ho,Wang, YiYi,Bae, Jinhyung,Han, Jung Hoon,Sohn, Uy Dong The Korean Society of Pharmacology 2015 The Korean Journal of Physiology & Pharmacology Vol.19 No.5

To see the inhibitory mechanism of gentamicin in response to electrical field stimulation (EFS) using the rat bladder smooth muscle, atropine or guanethidine was treated but had no effect. Methylsergide, a non-selective 5-$HT_1$, 5-$HT_2$ receptor antagonist was also treated but had on effect. Kinase inhibitors, such as chelerythrine (PKC inhibitor), ML-9 (MLCK inhibitor), or Y27632 (rho kinase inhibitor) were pretreated before gentamicin treatment, but did not have effect. For U73122, a phospholipase C (PLC) inhibitor however, the inhibitory effect to gentamicin was significantly attenuated in all frequencies given by the EFS. Therefore gentamicin induced inhibitory effect on EFS response in rat bladder smooth muscle was not mediated by the activation of adrenergic, cholinergic, or serotonergic receptor. The inhibition of gentamicin might be mediated through the PLC dependent pathway, but not through the PKC, MLCK or rho kinase dependent pathway.
