In this study, we aimed to shed light on the effects of Ni–Ca interaction activity urease enzyme and incidence blossom end rot (BER) in tomato (Solanum lycopersicum) fruits. Therefore, Micro-Tom plants were grown under different levels Ni (0.0 1.0 mg dm–3) Ca2+ (0.35 0.70 g dm–3), both alone combination. Increased yields activity, as well inhibition BER, observed for fruits with Ni, even low Ca...

Although calcium (Ca) concentration in cellular compartments has been suggested to be tightly regulated, Ca deficiency disorders such as blossom-end rot (BER) in tomato (Solanum lycopersicum) fruit may be induced by abnormal regulation of Ca partitioning and distribution in the cell. The objectives of this work were to analyze the effects of high expression of the constitutively functional Arab...

BACKGROUND Non-small cell lung cancer is associated with high expression of multidrug resistance (MDR) proteins and low production of reactive oxygen species (ROS). Coptis extract (COP), a Chinese medicinal herb, and its major constituent, berberine (BER), have anticancer properties. This study aims to investigate the effects of COP and BER combined with chemotherapeutic agents, including fluor...

background: we aimed to determine the frequency of liver copper storage diseases in iranian children with cryptogenic chronic liver disease (cld). materials and methods: one-hundred and twenty children (52 girls, 70 boys; age range: 3 months-14 years) with cld who attended children's medical center in tehran, iran during the years 1997 through 1999, were enrolled. all viral, metabolic and autoi...

Mitochondrial DNA is thought to be especially prone to oxidative damage by reactive oxygen species generated through electron transport during cellular respiration. This damage is mitigated primarily by the base excision repair (BER) pathway, one of the few DNA repair pathways with confirmed activity on mitochondrial DNA. Through genetic epistasis analysis of the yeast Saccharomyces cerevisiae,...

Abstract: For alleviating the high peak-to-average power ratio (PAPR) problem of orthogonal frequency division multiplexing (OFDM) while improving the bit error rate (BER) performance, the OFDM combined with time division multiplexing (TDM) using frequency-domain equalization (FDE) is proposed. In this paper, the theoretical BER analysis of the OFDM/TDM in a frequency-selective fading channel i...

Real-time on-chip measurement of bit error rate (BER) for high-speed analog-to-digital converters (ADCs) does not only require expensive multi-port high-speed data acquisition equipment but also enormous post-processing. This paper proposes a low-cost built-in-self-test (BIST) circuit for high-speed ADC BER test. Conventionally, the calculation of BER requires a high-speed adder. The presented ...

Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can provide a better bit error rate (BER) performance than rake combining. To further improve the BER performance, cyclic delay transmit diversity (CDTD) can be used. CDTD simultaneously transmits the same signal from different antennas after adding different cyclic delays to increase the number of equiv...

BER Characteristic for the Broadband Radio Channel at 5.2 GHz1 Matthias Lott, Peter Seidenberg, Stefan Mangold2 Abstract| One major problem in the design of an air interface is the assessment of the impact of the radio channel on the BER and thus on the protocols. Besides realistic channel modeling a realistic BER calculation is needed. This results in a trade o between realistic and fast BER c...
