Effect of Oryzanol and Ferulic Acid on the Glucose Metabolism of Mice Fed witha High-Fat DietMyoung Jin Son, Catherine W. Rico, Seok Hyun Nam, and Mi Y oung Kang Abstract:The effects of oryzanol and ferulic acid on the glucose metabolism of high-fat-fed mice were investigated. Male C57BL/6N mice were randomly divided into 4 groups: NC group fed with normal control diet; HF group fed with high-fat (17%) diet; HF-O group fed with high-fat diet supplemented with 0.5% oryzanol; and HF-FA group fed with high-fat diet supplemented with 0.5% ferulic acid. All animals were allowed free access to the experimental diets and water for 7 wk. At the end of the experimental period, the HF-O and HF-FA groups exhibited significantly lower blood glucose level and glucose-6-phosphatase (G6pase) and phosphoenolpyruvate carboxykinase (PEPCK) activities, and higher glycogen and insulin concentrations and glucokinase (GK) activity compared with NC and HF groups. The results of this study illustrate that both oryzanol and ferulic acid could reduce the risk of high-fat diet-induced hyperglycemia via regulation of insulin secretion and hepatic glucose-regulating enzyme activities.Keywords: diabetes, ferulic acid, high-fat-fed mice, hypoglycemic effect, oryzanol IntroductionChronic consumption of a high-fat diet has been associated with the development of obesity and type 2 diabetes mellitus (Hill and others 1992; Bray and others 2004). Scientific studies have shown that excessive intake of dietary fat results in increased body weight and poor glucose regulation (Alsaif and Duwaihy2004; Petro and others 2004; Messier and others 2007). Diabetes is characterized by hyperglycemia that results in the generation of free radicals leading to oxidative stress (West 2000). Due to changes in lifestyle patterns, particularly poor eating habit and sedentary lifestyle, the incidence of diabetes has rapidly increased in epidemic proportions. Around 171 million cases of diabetes worldwide were reported in 2001 and it was projected that by 2030, 366 million people will have diabetes (Wild and others 2004). With this increasing global prevalence of diabetes, the need for therapeutic measures against the disease has become stronger and more urgent. A wide range of oral medicines are currently being used for treating diabetes. However, various adverse effects and high rates of secondary failures have been associated with the available antidiabetic medicines (Inzucchi 2002). Thus, finding natural drugs with hypoglycemic activity has now become the focus of scientists and researchers.At present, there is a considerable public and scientific interest in utilizing phytochemicals for the treatment and prevention of various diseases. Naturally occurring phenolic compounds, such as oryzanol and ferulic acid, are known to have strong antioxidant activities (Wang and others 2002; Srinivasan and others 2007). Oryzanol is a mixture of ferulic acid (4-hydroxy-3-methoxycinnamic acid) esters with phytosterols (Lerma-Garcia and others 2009) and primarily extracted from rice bran. Ferulic acid is commonly found in fruits and vegetables, including banana, broccoli, rice bran, and citrus fruits (Zhao and Moghadasian 2008). Both oryzanol and ferulic acid possess several physiological proper ties, such as reduction of serum cholesterol levels (Wilson and others 2007), inhibition of tumor promotion (Y asukawa and others1998), and protective action against liver injury (Choti-markorn and Ushio 2008). Oxidative stress is regarded as the key factor in the development of diabetes and its associated health disorders. The high-fat diet fed C 57BL/6 mouse model has long been used by researchers in investigating the pathophysiology of impaired glucose tolerance and type 2 diabetes and for the development of new treatments (Surwit and others 1988; Surwit and other s 1991; Schreyer and others 1998; Winzell and Ahren 2004). Since diabetes is a free radical mediated disease, the strong antioxidant activity of oryzanol and ferulic acid may be useful in preventing the development of diabetic hyperglycemia under a high-fat diet. There are limited reports on the physiological functions of these phenolic compounds in relation to glucose metabolism in animal models. Thus, this study was conducted to investigate the effects of dietary feeding of oryzanol and ferulic acid on the glucose metabolism in high-fat-fed C57BL/6 mice. 1. Materials and Methods1.1 Animals and dietsTwenty-four male C57BL/6N mice of 4 wk of age, weighing 12 g, were obtained from Orient Inc. (Seoul, Korea). They were individually housed in stainless steel cages in a room maintained at 25◦C with 50% relative humidity and 12/12 h light/dark cycle and fed with a pelletized chow diet for 2 wk after arrival. The mice were then randomly divided into 4 dietary groups (n = 6). The 1st and 2nd groups were fed with a normal and high-fat (17%, w/w) diets, respectively, while the other 2 groups were fed with high-fat diet supplemented with either 0.5% oryzanol or 0.5% ferulic acid (>98% pure, Tsuno, Osaka, Japan). The composition of the experimental diet (Table 1) was based on the AIN-76 semisynthetic diet.The mice were fed for 7 wk and allowed free access to food and water during the experimental period. The body weight gain was measured weekly. At the end of the experimental period, the mice were anaesthetized with 60-μL Ketamine-HCl following a 12 h fast and sacrificed. Blood samples were collected and centrifuged at 1000 × g for 15 min at 4◦C to obtain the plasma. The livers were removed, rinsed with physiological saline, and stored at −70◦C until analysis. The current study protocol was approved by the Ethics Committee of Kyungpook Natl. Univ. for anima studies. 1.2 Measurement of blood glucose levelThe blood glucose level in mice was measured using Accu-Chek Active Blood Glucose Test Strips (Roche Diagnostics GmbH, Germany). Blood samples were drawn from the tail vein of the mice before and after 3 and 7 wk of feeding theanimals with experimental diets.1.3 Determination of glycogen and insulin levelsThe glycogen concentration in liver was determined using the method described by Seifter and others (1950)。

Abstract – In this paper, we introduce a high-speed and low power Phase-Frequency Detector (PFD) that is designed using modified TSPC (True Single-Phase Clock) positive edge triggered D flip-flop. This PFD has a simpler structure with using only 19 transistors. The operation range of this PFD is over 1.2Ghz without additional prescaler circuits. Furthermore, the PFD has a dead zone less than 0.01ns in the phase characteristics and has low phase sensitivity errors. The phase and frequency error detection range is not limited as in the case of the pt-type and nc-type PFDs [3]. Also, the PFD is independent from the duty cycle of input signals. A new charge-pump circuit is presented that is designed using a charge-amplifier. A stand – by current enhances the speed of charge – pump and removes the charge – sharing which causes a phase noise in the charge – pump PLL. Also, the effects of clock feed – through are reduced by separating the output stage from UP and down signal. The simulation results base on a third – order PLL are presented to verify the lock – in process with the proposed PFD and Charge – pump circuits. The PFD and charge – pump circuits are designed using 0.8 µm CMOS technology with 5V supply voltage.I. I NTRODUCTIONThe input phase errors are detected by Phase - Detector (PD) or Phase – Frequency Detector (PFD). These errors, phase or frequency errors, are converted into current or voltage to control the output frequency of V oltage Controlled Oscillator (VCO) by charge pump in a charge –pump PLL. PD detects a phase error between the reference signal and the output signal of PLL. And the error detection range can be extended with PFD. A conventional CMOS PFD [1] is shown in Fig.1. This PFD has large dead zone in phase characteristics at the steady state which generates a large jitter in locked state in PLL. Also, a large amount of power consumption cannot be avoided in high frequency operations because internal nodes of PFD are not completely pull up or pull down. The additional prescaler circuits can be added to lower frequency of the input signals. However, as the division ratio increases, the steady state phase error will increase. A pt-type [2] and a nc-type PFDs [3] are shown in Fig.2 A pt-type PFD [Fig2.b] has very high speed, but dead zone exists. A nc-type PFD [Fig2.a] has no dead-zone, but phase characteristics depend on a duty cycle of input signals. The capture range of PLL is determined by the error detection range of PFD. A conventional CMOS PFD has no limit to the error detection range. Therefore, the capture range of PLL is only limited by the V oltage Controlled Oscillator (VCO) output frequency range [5]. However, the error detection ranges of pt-type and nc-type PFDs are limited within -π∼ +π. So the capture range of PLL with these PFDs is only limited by input reference signals.The PFD and charge-pump circuits provide a transfer function of input phase error to the output charge per clock cycle [4]. Whenever UP and DOWN signals are switching, a conventional tri-state charge-pump [1] has problems such as charge sharing in high impedance- state, charge injection and clock feed through [5]. The clock feed through andA High Speed and Low Power Phase-Frequency Detector and Charge - pumpcharge sharing introduce a step phase noise to a charge –pump PLL.We propose a simple sequential type PFD circuit which uses modified TSPC positive edge triggered D flip-flop whose phase and frequency error detection range is not limited. Also, we present a new charge-pump circuit which is designed using a current - amplifier. The charge-pump reduces the effects of clock feed through and a charge sharing.In section II and III, the proposed positive edge triggered D flip-flop and charge-pump circuit is described respectively. The phase and frequency characteristics of proposed PFD circuit are presented, and comparisons are made in section IV. In section V, a third - order PLL is designed to check the lock-in properties of proposed PFD and charge-pump circuits. In section VI, draw a conclusions.II. D ESIGN OF POSITIVE EDGE TRIGGERED D FLIP -FLOPA circuit schematic of proposed D flip-flops is shown in Fig. 3. These flip – flops are modified the TSPC flip-flop [6] to satisfy the required function of D flip-flop for PFD. The operations of the proposed D flip – flop are very simple. When input clock and reset signals are low, the node A is connected to VDD through m1, mr1 and charges the node A to VDD. At the rising edge of the clock signal, output node is connected to ground through m3 and m4. Once the node A is charged to VDD, the output node is not affected by input clock signal. Because the charges at node A turn off the m3 and this prevents the output node from pulled up. Therefore, the output node is disconnected from input node. When the reset signal is applied, node A is disconnected from VDD by mr1 and connected to ground by mr2. As soon as the node A is discharged, the output node is pulled up through m2. The mr1 is added to prevent the short – circuit that happens whenever the reset signal is applied. If the clock signal is low in the condition of reset signal is high, a current path is made from VDD to ground without mr1. This increases the power consumption. Moreover, the reset time is increased because m1 charges the node A to VDD while the mr2 discharges node A to ground. Fast discharging node A means the fast reset operation. The operations of D flip –flop in Fig3.a and Fig.3.b are same but the connection is different. Dynamic power consumption can be reduced by lowering the internal switching and speed is increased by shortening the input to output path.Full schematic of proposed PFD is shown in Fig.4. A conventional sequential type PFD structure is used. And for high-speed operation, a pseudo - NOR gate is used.III. D ESIGN OF CHARGE - PUMPA proposed charge-pump circuit is shown in Fig.5. The charge – pump consists of current amplifier with stand-by current and switched current source. The operation of charge – pump is similar to the conventional tri-state charge-pump. But the control switch is not connected directly to the output stage in order to reduce the effect of clock feed – through which causes the step phase - jump error whenever the UP/DN signals make transition. And stand - by current source added to the input of the charge – pump to enhance the speed of charge - pump. Also the stand – by current eliminates high – impedance state in the tri-state charge-pump which causes a charge sharing problems. The output current of charge - pump is same as conventional tri-state charge – pump. The stand-by current does not affect the output current only enhance the speed of charge - pump.ckqb ResetckqbReset(a) proposed D flip-flop 1.(b) proposed D flip-flop 2. Fig.3.

Switch is implemented using transmission gate to reduce clock feed - through and the current mismatch caused by path delay mismatch can be reduced. Cascode current sources are used to increase the output impedance.IV. P HASE CHARACTERISTICSFig.8. shows the phase characteristics of proposed PFD together with pt-type PFD and nc-type PFD. The pt-type PFD has 0.15ns dead zone and nc-type PFD has constant offset in phase characteristics. Moreover, nc-type PFD depends on the duty cycle of the input signals. The nc-block or flip-flop of nc-type and pt-type PFD are controlled by both input signals while the proposed PFD does not depend on other input signals. So the phase sensitivity error caused by input signal dependence is reduced. Phase sensitivity errors of pt-type PFD, nc-type PFD and proposed PFD are shown in Fig.8. Phase sensitivity errors are reduced less than 0.02ns with proposed PFD. The nc-type PFD has variousphase offsets caused by the duty cycle of input signals. The pt-type PFD has similar phase characteristic to the proposed PFD. However, since the flip-flops are controlled by both input signals, the output signal is dependent on the state of input signals. This increases the phase sensitivity error.Setup and reset delay of proposed PFD as a function of supply voltage are shown in Fig.9. The setup delay of proposed PFD varies from 0.1ns up to 0.25ns as supply voltage decreases. But the reset delay varies from 0.45ns up to 1.45ns because of the delay of NOR gate increases significantly.V . V ERIFICA TION OF PFD AND CHARGE –PUMP WITH THIRD –ORDER CHARGE – PUMP PLLIn order to verify the lock – in properties of the proposed PFD and charge – pump, a complete third order charge –pump PLL was designed. The circuit schematic of VCO [6]and Loop – Filter is shown in Fig 10. The output frequency range of VCO measured from 650MHz up to 1.4Ghz. The gain of VCO is measured -592MHz/V . The key parameters of loop-filter are as follows. [R1=8K, R2=1K, C1=10pF,C2=2pF].VSSVDDVDDVSSoutFig.6.

The steady state phase error (clock skew) measured 10.2ps.VI. C ONCLUSIONSFor high speed and low power CMOS PLL, we proposed a dynamic CMOS positive edge triggered D flip-flop for PFD and current amplifier charge – pump circuit. The proposed PFD has simpler structure and lower power dissipation. The dead zone of PFD is less than 0.01ns and error detection range is not limited. The proposed charge amplifier type charge – pump circuit reduces the effects of clock feed –through. Also, stand – by current removes the charge –sharing at high impedance state and the speed of the charge – pump circuit is increased. A simulation results based on a third - order PLL indicates that the proposed PFD operates over 1.2Ghz without additional prescaler circuits in 0.8-µm CMOS with 5Vsupply voltage. The steady state phase errors are measured less than 12ps and jitter is reduced to 15ps at 1.27Ghz input reference. The proposed dynamic CMOS PFD and charge amplifier type charge – pump circuits can be used in high frequency region over 1.2Ghz with precise and fast lock – in process.R EFERENCES[1] R.E.Best, Phase – Locked Loops , 2nd ed.

It is a heat regenerative desiccant dehydrator designed to operate on -48 / -60 V DC. The desiccant automatically regenerates by periodic heating and requires no scheduled maintenance. It will supply up to 300 liters per hour (10.6 scfh) of air with a dew point of better than –45°C (–49°F) at a nominal pressure of 3 kPa (0.44 psig).The HR300 is designed for mount in a standard 19” equipment rack and has an option for ETSI N3 rack-mounting with adapter plates (sold separately). The HR300 requires 2 rack units to mount.Dry air is supplied to the transmission lines by four independent outlets located on the rear of the chassis.Ambient air is drawn through desiccant beds by two low power diaphragm compressors. The adsorbent material in the desiccant canisters removes moisture from the ambient air prior to passing it through the internal manifold where the system pressure and humidity level (optional) is monitored.System pressure dictates demand and theHR300 will respond by changing the speed of the compressors allowing the dehydrator to function without pressure switches or regulators. This increases compressor life and overall unit reliability. Section5 Installation5.1 UnpackingThe HR300 includes all necessary brackets andelectrical terminations to successfully install theunit in a site.Installation of the HR300 requires the followingtools:•#1 and #2 Phillips head screw drivers•Wire cutters and wire strippers foralarm terminationsJ2 Alarm Connection4 OUTPUT PORTS-48/-60 DC POWER CONNECTOR5.2MountingCAUTION: The HR300 utilizes heat to regenerate the drying canisters. Mount the HR300 at the top of the equipment rack. The heat created by the HR300 is dissipated out of the top and side of the dehydrator. DO NOT mount any equipment above the HR300.5.2.1 19” Rack MountingAttach the supplied rack brackets with theincluded screws to the front mounting holes for installation in a standard 19” equipment rack as illustrated below. The hardware necessary for mounting to the equipment rack is not included5.2.2 Wall MountingInstall the standard 19” rack brackets on the rear of the chassis with the included screws as illustrated below. The brackets will provide enough clearance for the tubing and electrical connections.Secure the unit to the wall using appropriate fasteners for the wall material. The hardware for mounting to the wall is not included.5.3Electrical ConnectionsCaution: The ON/OFF switch on the front must be switched off prior to disconnecting the dehydrator from the power supply prior to servicing.A protective earth terminal is available through the power connector J1 and is marked by the Earth Ground symbol.Additionally, there is an external ground stud that can be used for additional electrical protection.5.3.1Power ConnectionsVerify that the power supply is the correct type and rated voltage prior to connecting theHR300. See power ratings label on rear side of the dehydrator.The power cable comes pre-terminated for connection to J1 on the rear of the dehydrator. The HR300 incorporates reverse polarityprotection. If the unit does not power up when connected to the DC supply, verify polarity and correct if necessary. The supply end of the power cable is left un-terminated to accommodate any type of power supply. If the proper DC power supply voltage is connected to the dehydrator and the power switch is turned on but the unit fails to operate, verify the polarity. If the polarity is incorrect, have it reversed and then re-connect to the dehydrator. The HR dehydrators are equipped with reverse polarity protection, but will not operate under reverse polarity. Polarity for the power cable is: Red – Positive Black – Negative White - Ground5.3.2Alarm ConnectionsAlarm wiring will need to be provided by the customer at the installation site.5.4Pneumatic ConnectionsThe HR300 has a quantity of four 9.5 mm (3/8 in) compression fittings located on the rear of the chassis. The dehydrator is shipped with one port open to ambient air. The other three ports are plugged with pressure caps in order to prevent air from escaping from these ports when not in use. In order to use theseadditional ports, simply remove the pressure caps.5.4OperationConnect the included tubing to an open port on the rear of the unit. All unused ports must beplugged with pressure caps. Turn on the power switch located on the front face. The LED will illuminate.The first compressor will start and air will beginflowing to the transmission line(s).If this is a new installation, the transmissionlines must be purged by creating a small leak atthe far end of the transmission lines andallowing the dehydrator to pump dry air throughthem.A minimum of three air volume exchanges isrequired. If the installation is located in a veryhumid area, up to twelve air exchanges may benecessary to properly purge the transmissionline. The time, in hours, necessary to exchangethe air one time is based on the total air volume(V) of the waveguide and antenna system.Purging time (hours) = (3 x V) / 300, where V isline volume in litersAt the conclusion of the purging cycle, close thefar end of the transmission lines.5.6 AlarmsThe HR300 is equipped with an LED on the frontpanel for a visual indication of alarm conditions.A green LED indicates all is well with thedehydrator.
