Involvement of E2F1 transcriptional activity in cadmium‐induced cell‐cycle arrest at G1 in human lung fibroblasts
Authors: Choi You‐Jin , Yin Hu‐Quan , Suh Hyo‐Ryung , Lee Young‐Ju , Park So‐Ra , Lee Byung‐Hoon
Published: May 2010

Human cadmium (Cd) exposure is associated with cancers of the lung and kidney. Using cDNA microarray analysis, we have recently reported that the expression of E2F1 is reduced by Cd in human lung fibroblasts, indicating the possibility of G1‐phase arrest. To test this hypothesis, we investigated the effects of Cd on the cyclin‐dependent kinase (CDK2) and retinoblastoma protein (Rb) regulatory pathways in WI38 human lung fibroblasts. We demonstrate here that G1‐phase accumulation was induced by Cd in WI38 (wild‐type for p53 and Rb), but not in the SV40 large T antigen‐transformed variant WI38‐VA13 (p53‐ and Rb‐defective). Cd‐induced cell‐cycle arrest was associated with a decrease in CDK2 protein and with increase in p21 expression and p53 phosphorylation. Cd treatment caused a distinct increase in the formation of p21‐cyclin E‐CDK2 complex, as revealed by immunoprecipitation. The level of Rb‐E2F1 complexes was increased, and the translocation of E2F1 to the nucleus was decreased by Cd treatment. Consequently, the transcriptional activity of E2F1 and the expression of the E2F1 target genes were also decreased by Cd. These results clearly demonstrate that Cd‐mediated G1 arrest in WI38 cells is associated with the suppression of Rb phosphorylation and with the inhibition of E2F1 transcriptional activity. Environ.

Kynurenine inhibits chondrocyte proliferation and is increased in synovial fluid of patients with septic arthritis

Kynurenine, the major degradation product of tryptophan has been shown to directly damage various tissues. Its potential contribution to septic arthritis is unknown. In this study, we analyzed the putative diagnostic value of kynurenine for bacterial joint infection and its potential harmful effects on cartilage. In a prospective study 41 patients with a joint effusion who had undergone arthrocentesis were included. Tryptophan and kynurenine levels from synovial fluid were quantified by HPLC. Diagnostic value of kynurenine was evaluated and its effects on the proliferation of the chondrocyte cell line ATDC5 were determined. Synovial fluid kynurenine values from patients with septic arthritis (4.1 ± 0.8 µmol/L, n = 9) were significantly increased compared to patients with non‐infectious inflammatory arthropathy (1.8 ± 0.2 µmol/L, n = 17) or osteoarthritis (1.2 ± 0.1 µmol/L, n = 15, p < 0.01). At a cut‐off value of 2.28 µmol/L kynurenine had a sensitivity of 0.89 and a specificity of 0.87. Further, kynurenine inhibited chondrocyte (ATDC5) cell proliferation in a dose‐dependent manner. Septic arthritis is associated with significantly increased values of synovial kynurenine. Furthermore kynurenine inhibits proliferation of chondrocytes, which strongly suggests a pathophysiological effect of kynurenine on cartilage in inflammatory arthropathies. © 2010 Orthopaedic Research Society.

Mesenchymal stem cells (MSC) are increasingly replacing chondrocytes in tissue engineering based research for treatment of osteochondral defects. The aim of this work was to determine whether repair of critical‐size chronic osteochondral defects in an ovine model using MSC‐seeded triphasic constructs would show results comparable to osteochondral autografting (OATS). Triphasic implants were engineered using a beta‐tricalcium phosphate osseous phase, an intermediate activated plasma phase, and a collagen I hydrogel chondral phase. Autologous MSCs were used to seed the implants, with chondrogenic predifferentiation of the cells used in the cartilage phase. Osteochondral defects of 4.0 mm diameter were created bilaterally in ovine knees (n = 10). Six weeks later, half of the lesions were treated with OATS and half with triphasic constructs. The knees were dissected at 6 or 12 months. With the chosen study design we were not able to demonstrate significant differences between the histological scores of both groups. Subcategory analysis of O'Driscoll scores showed superior cartilage bonding in the 6‐month triphasic group compared to the autograft group. The 12‐month autograft group showed superior cartilage matrix morphology compared to the 12‐month triphasic group. Macroscopic and biomechanical analysis showed no significant differences at 12 months. Autologous MSC‐seeded triphasic implants showed comparable repair quality to osteochondral autografts in terms of histology and biomechanical testing. © 2010 Orthopaedic Research Society.

Miniature 1.87‐dB insertion‐loss V‐band CMOS bandpass filter with two enhanced finite transmission zeros
Authors: Chang Jin‐Fa , Lin Yo‐Sheng
Published: May 2010

In this article, we demonstrate a miniature low‐insertion‐loss V‐band bandpass filter with two finite transmission zeros by standard 0.13‐μm CMOS technology.The proposed filter architecture has the following feature: the low‐frequency transmission‐zero and the high‐frequency transmission‐zero can be tuned by the series‐feedback capacitorCsand the parallel‐feedback capacitorCp, respectively. ParallelLCcircuits (i.e.,C12in parallel withLC1‐C11‐LC2andC22in parallel withLC3‐C21‐LC4) are used for implementingC1andC2to improve the roll‐off characteristic at high frequency and the depth of the upper notch. Besides, low‐insertion‐loss was achieved by adopting thick microstrip‐line (MSL) with optimized ground‐plane pattern as the needed inductors to minimize both the metal loss and the substrate loss. Over the frequency range of 49.5–82.5 GHz, the filter achieved insertion‐loss (1/S21) lower than 3 dB, and input return loss (S11) and output return loss (S22) better than −10 dB. The minimum insertion‐loss was 1.87 dB at 66.5 GHz, a state‐of‐the‐art result for a V‐band CMOS bandpass filter. The chip area was only 0.466 × 0.307 mm2, i.e., 0.143 mm2, excluding the test pads. © 2010 Wiley Periodicals, Inc.

Dual band–rejected microstrip antenna for WiMAX/WLAN applications
Authors: Lin Shun‐Yun , Ke Bi‐Jin
Published: May 2010

In this article, we propose a novel design to obtain dual band–rejected characteristics in printed microstrip antenna.First, an ultrawide operating band from 2.15 GHz to about 6.50 GHz is achieved by locating the rectangular radiating patch above a larger rectangular notch cut in the finite ground plane edge. Two folded strips with different length protrude from the patch corner with null surface current to introduce dual rejected band. The longer strip and shorter strip are independently associated with lower and upper rejected band. By suitable adjustment in strip lengths, two rejected bands centered at 3 and 4.7 GHz are successfully introduced. Also, a triband operation for 2.5/3.5/5.5 GHz WiMAX and 2.4/5.2/5.8 GHz WLAN applications is achieved for the proposed microstrip antenna. Details of the design considerations are presented, and results of the implemented prototype are discussed. © 2010 Wiley Periodicals, Inc.

We propose a new design of a Vehicular Ad Hoc network (VANET) system that uses the dense wavelength division multiplexing wavelength enhancement, whereas the increasing in channel capacity and signal security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the central operator. The optical communication wavelength enhancement is reviewed.

Design method for satellite output multiplexer low‐pass filters exhibiting spurious‐free frequency behavior and high‐power operation

Published: May 2010

In this article, a design method for high‐power low‐pass filters with wide rejection band is proposed for rectangular waveguide technology. The new filters consist of a classical high‐power E‐plane corrugated low‐pass filter that is cascaded with a quasi‐periodic structure tuned to reject its undesired intrinsic spurious passbands. The new design technique presented here does not impose any limitations on the gap aperture of the original E‐plane corrugated filter. This allows the minimum gap of the corrugated filter to be kept wide which, along with the smoothness and the wide gap of the quasi‐periodic structure itself, enables high‐power TE10 mode operation in the whole structure as the spurious passbands are suppressed. An example will be given in Ku‐band. The resulting prototype will have several kilowatts handling capability and the spurious passbands will be suppressed up to the third harmonic (around 40 GHz). The new design method may have an important practical impact in the design of the low‐pass filter required at the output of the satellite output multiplexers. © 2010 Wiley Periodicals, Inc.

Multiband MIMO antenna with independent resonance frequency adjustability
Authors: Han Min‐Seok , Choi Jaehoon
Published: May 2010

A compact multiband multiple‐input multiple‐output (MIMO) antenna with a band stop matching circuit for next generation mobile applications is proposed. The proposed multiband MIMO antenna consists of two dual‐band planar inverted‐F antennas, which provide wideband characteristics. To improve the isolation characteristic at the long term evolution band, a band stop matching circuit was inserted at the corner of each antenna element. The proposed MIMO antenna has isolation of ∼15 dB at the lower band and over 20 dB at the upper band. In addition, the resonant frequencies of the proposed MIMO antenna can be independently tuned by changing the value of the inductor or by adjusting the widths of Slit1 and Slit2. To evaluate the performance of the proposed antenna, key performance parameters such as total efficiency, envelope correlation coefficient, mean effective gain (MEG), and the MEG ratio are analyzed. © 2010 Wiley Periodicals, Inc.

Published: May 2010

In this article, we present a high‐gain low‐profile resonant cavity antenna that utilizes a novel metamaterial surface as a superstrate. Due to the low‐reflection phase value of the metamaterial superstrate, the thickness of the resonant cavity antenna is significantly thinner than the operating wavelength. Several important parameters that characterize the metamaterial superstrate are investigated based on the unit cell simulation. The proposed antenna is fabricated and measured. The experimental results show that the prototype can provide a high‐gain at the operating frequency. © 2010 Wiley Periodicals, Inc.

A CMOS differential fifth‐derivative Gaussian pulse generator for UWB applications
Authors: He Jin , Zhang Y. P.
Published: May 2010

A CMOS differential fifth‐derivative Gaussian pulse generator is presented for Ultrawideband (UWB) applications. The design exhibits low‐power consumption, low‐circuit complexity, and precise pulse shape to inherently comply with the FCC spectrum mask for indoor UWB applications without the need for a filter. The proposed differential pulse generator was implemented with a 1.8‐V, 0.18‐μm CMOS process, but only the positive fifth‐derivative Gaussian pulse was measured owing to the limitation of the available testing facilities. The measured pulse has peak‐to‐peak amplitude of 154 mV and a pulse width of 820 ps. Small core area of the differential pulse generator is only 0.028 mm2 because of its all digital circuit design. The average power dissipation is 1.2 mW with a pulse repetition frequency (PRF) of 50 MHz. © 2010 Wiley Periodicals, Inc.

Neuromuscular junction morphology, fiber‐type proportions, and satellite‐cell proliferation rates are altered in MyoD−/− mice
Authors: Macharia Raymond , Otto Anthony , Valasek Petr , Patel Ketan
Published: May 2010

Gene compensation by members of the myogenic regulatory factor (MRF) family has been proposed to explain the apparent normal adult phenotype of MyoD−/− mice. Nerve and field stimulation were used to investigate contraction properties of muscle from MyoD−/− mice, and molecular approaches were used to investigate satellite‐cell behavior. We demonstrate that MyoD deletion results in major alterations in the organization of the neuromuscular junction, which have a dramatic influence on the physiological contractile properties of skeletal muscle. Second, we show that the lineage progression of satellite cells (especially initial proliferation) in the absence of MyoD is abnormal and linked to perturbations in the nuclear localization of β‐catenin, a key readout of canonical Wnt signaling. These results show that MyoD has unique functions in both developing and adult skeletal muscle that are not carried out by other members of the MRF family. Muscle Nerve, 2010

Published: May 2010

The procedure allowing single‐step formation of microscaled thermostable polymer honeycomb patterns is reported. Polymer substrates soluble in chlorinated solvents were pulled from the solvents before their final dissolution and placed into a humid atmosphere. Honeycomb patterns were deposited by this method on polyetherimide, polysulfone (PSF), and polyethersulfone (PESF) substrates. PSF and PESF substrates demonstrated reversibly switchable wetting under UV irradiation/heating cycles strengthened by the Cassie–Baxter wetting regime. Copyright © 2010 John Wiley & Sons, Ltd.
