The role of saliva in the process of oxidative stress – review of literature Rola śliny w procesie stresu oksydacyjnego

Background: Saliva constitutes a first line of defence against free radical-mediated oxidative stress, since the process of mastication and digestion promotes lipid peroxidation. During gingival inflammation, gingival crevicular fluid flow increases the change of saliva composition with products from the inflammatory response, modulating oxidative damages in the oral cavity. Authors review the current literature concerning the reactive oxygen species, oxidants, pro-oxidants and antioxidants in saliva, and methods for assessing the antioxidant capacity of saliva. Comparison of salivary antioxidant status in male and female subjects reveales a significant gender-related difference in saliva composition. The current data demonstrate a significant enhancement of the salivary antioxidant system in juvenile idiopathic arthritis patients. Also patients with chronic renal failure, diabetes and on hemodialysis show increase oxidative stress burden in both serum and saliva. The finding of reduced oral peroxidase levels in smoking subjects may represent a contributory mechanism for initiation and progression of cigarette smoke-related oral diseases such as oral cancer. The results of recent studies indicate that the total antioxidant capacity of saliva decreased in children with HIV infection. Conclusion: Whole saliva may contain simply measured indicators of oxidative processes. This may provide a tool for the development and monitoring of new treatment strategies. A non-invasive determination of the salivary concentrations of antioxidants such as superoxide dismutase (SOD) and uric acid (UR) allows the evaluation of the defensive capacity of the oral mucosa. Still, there is a need for standardization of methods for saliva sampling and testing protocol.
the key metaethical

This study offers interpretative insights into Kierkegaard’s thought and his understanding of the term “truth” in metaethical relations. Metaethics, though not explicitly presented and used as a term in Kierkegaard's writings, yet represents the implicit framework of his thinking about the life of man, his responsibility, individual life development, and the teleological anticipation of his existence. The thesis presents the concept of truth as an interdisciplinary overlap of metaphysics, epistemology, and philosophy of the mind that can be identified in various Kierkegaardian works and be related to, so selected writings are being examined here. It turns out that, depending on the concealed intention of the author, different aspects of such interdisciplinary complex emerge in different works, which are permeated into the way how Kierkegaard put the word "truth" into different contexts.

EFFECT OF AN ORGANOPHOSPHOROUS INSECTISIDE DICHLOROVOS ON THE REPRODUCTIVE PERFORMANCE IN MALE RAT (RATTUS NORVEGICUS)

Dichlorovos is widely used as a potent pesticide in many countries and has been shown to produce some adverse health effects. The present investigation was designed to clarify whether dichlorovos causes detectable adverse effects on rat testes. Dichlorovos was administered to rats orally at dose level of 20 mgkg -1 bwt. -1 day -1 for 45 days. Study showed significant (P<0.05) decline in the body weight and reproductive organs weight, and significant (P<0.05) reduction in sperm counts with 80% infertility in dichlorovos treated animals. A significant reduction in testicular glycogen (P<0.05) and sialic acid (P<0.01) was also noticed. Contrary to these, protein (P<0.01) and cholesterol (P<0.05) contents of testes were significantly increased. In addition, serum acid phosphatase activity significantly (P<0.05) increased, while serum alkaline phosphatase (P<0.05) and serum testosterone, LH and FSH levels (P<0.01) were diminished. Thus, the obtained results indicated that dichlorovos shows reproductive toxicity on biochemical and hormonal level in male albino rats.

Factors influencing the Use of Digital Technology by Secondhand and Bric-a-brac Sellers in Bangkok and Surrounding Provinces.

Continuously advancing technology has allowed people in modern society to complete many tasks in the comfort of their home through the use of digital technology. We have seen many past studies investigating factors influencing the use of new technology for selling brand-new products or providing services such as on e-commerce, online payments and online banking. However, there have not been many studies on factors influencing the use of digital technology for selling secondhand items. The objectives of this study were to 1. examine the current situation and de-mography of secondhand and bric-a-brac sellers in Bangkok and surrounding provinces and 2. examine factors influencing the utilization of digital technology by second-hand and bric-a-brac sellers in Bangkok and surrounding provinces. This study employed a mixed research methodology. Four hundred and thirteen sellers were asked to answer questionnaire at six largest flea markets in Bangkok and surrounding area through convenience random sampling method. Additionally, thirty in-depth interviews were also conducted to capture additional information. A research model was developed based on Technology Organization Environment Framework (TOE. integrated with Diffusion of Innovation theory (DOI. and Technology Acceptance Model (TAM. Proposed relationships between adoption of digital technology and sixteen independent variables were tested using Multiple Regression Analysis. The empirical evidence demonstrates that Pressure from competition, Innovativeness of business owner/manager and Ability of technology of business owner/manager were found to have significant positive relationship with adoption of digital technology. The results shed light on how to Thailand could improve the use of technology among tiny busi-1
Proposed heptagon graph for DGA interpretation of oil transformers

Dissolved gas analysis (DGA) is one of the most acceptable methods used for detecting and evaluating gases dissolved in mineral oil and also in the solid insulation of internal incipient faults in the power and distribution transformers based on the oil samples. DGA has been proved the most accurate method for condition assessment of power and distribution transformers. The fault types depend upon type and concentrations of each gas dissolved in oil. IEC, Rogers, Doernenburg and Duval techniques, in spite of their importance in diagnosing certain types of faults, do not consider the concentrations of carbon monoxide (CO) and carbon dioxide (CO2) to evaluate cellulose insulation degradation. Some of these techniques do not take into account the impact of ethane (C2H6) and hydrogen (H2) for the evaluation of fault types. A new graphical method “Heptagon” based on seven gases produced in faulty transformer oil decomposition is presented. Based on about 452 test samples of transformer oil DGA, the Heptagon figure is drawn and the zones of different fault types are determined. The suggested technique is tested and compared with other techniques.
EFFECTIVENESS OF CELLULAR MANUFACTURING

Previous studies suggest that despite their intuitive appeal, cellular manufacturing systems are only effective in a batch production environment under a limited set of conditions. However, these studies have not taken into account the potential for productivity improvements unique to shops organized around product and work groups. Improvements that yield processing time reductions and rapid movement down the learning curve may offset the limited flexibility that typically compromises the performance of cellular shops. This paper demonstrates that if a cellular shop can yield even–marginally greater reductions in processing times than a job shop, it can outperform a job shop under conditions previously thought to be unfavorable to a cellular shop. Learning curve theory is used to show that this can be achieved at modest levels of output and also under conditions not typically associated with cellular shop configurations.
Chloroplast genome of the conserved Aster altaicus var. uchiyamae B2015-0044 as genetic barcode

Endangered species conservation is a hot issue in botany. In Korea, ex situ Conservation Institutions play major roles in the propagation of and finding new habitats for rare species. Aster altaicus var. uchiyamae, an endemic endangered species, has potential horticultural and agricultural uses, suggesting that there are strong merits to conserving this species. The Danyang aster (Aster altaicus var. uchiyamae) is a useful garden plant with pink ray flowers. Recently, Mr. Lee of the Shingu Botanical Garden has developed a Danyang aster with white flowers. Unlike the other Dendranthema asterid species, which are pro pagated by cutting (Park et al., 2015), A. altaicus var. uchiyamae is a biennial and propagated by seeds. Aster altaicus var. uchiyamae Kitam. was first collected by K. Uchiyama on October 7, 1902 in Suanbo, Chungcheongbuk Province (Kitamura, 1937). The plant grows in limited quantities at roadsides and sandy riverbanks along the South Han River (personal observation). In the last decade, much of this species’ habitat was submerged by dam construction, thus its protection is urgent. Aster altai­ cus var. uchiyamae is protected by Korean law as an endan gered species and is included in the Korean Red List of Threatened Species (Suh and Kim, 2014). Lines of A. altai ­ cus var. uchiyamae have been propagated by the Korean Association for ex situ Conservation Institution (KAECI), supported by the Ministry of Environment, Rep ublic of Korea. Genetic information for native plants of different countries is provided in the Access to Genetic Resources and Benefit-Sharing development (ABS) under the Convention on Biological Diversity (CBD). Chloroplast (cp) genetic information has been used for more than three decades because of its maternal inheritance and sequence stability. In Aster, the first plastid genome was documented in A. spathulifolius (Choi and Park, 2015), which grows at seasides of Korea and Japan. The cp genome of A. altaicus var. uchiyamae was documented and the cp-DNA was compared to that of A. spathulifolius by Park et al. (2017). In the study, we reported that A. altaicus var. uchiyamae cp genome contains 112 genes and 21 introns and consisted of 79 protein-coding genes (PCGs), 4 RNA genes, 29 tRNA genes, and 3 pseudo-genes. Pseudo-genes include Journal of Species Research 10(2):154-158, 2021
Amplitude and Phase Independently Adjustable Transmitarray Aperture and Its Applications to High Gain and Low Sidelobe Antenna

This article introduces an amplitude and phase independently adjustable transmitarray aperture with a thin profile and low cost to fabrication characteristics, and a transmitarray antenna (TA) featuring the high gain and low sidelobe level (SLL) is realized based on it. The TA is made up of a standard feed horn and a transmitarray aperture, each of which comprises a three-layer metasurface that is well-designed to tune the transmitted phase and amplitude on its own. As a result, the transmitarray aperture can cover the 360° phase range required for phase compensation while also realizing the amplitude distribution calculated by the Taylor design, contributing to the low SLLs. The advantage of independently controlling the amplitude and phase not only enables the proposed TA to be easy to realize and less cost on optimization but also improves the performance of high gain and low SLLs with a low profile and easy fabrication. Theoretical analyses and simulations are carried out, and a prototype is fabricated and measured. At 10 GHz, the measured peak gain is 21.16 dBi, with SLLs of −31.21 and −29.93 dB in the H- and E-planes, respectively. As a result, the tight agreements between measurement and simulation validate the design concept.
NVIDIA MATHS: Mechanism to Access Test-Data Over High-Speed Links

The Mechanism to Access Test-Data over High-Speed Link (MATHS) provides a high-throughput PCIe-based system to structurally test system-on-chips (SoCs) at wafer and system levels. With this system, the SoC can be directly tested at the system level and the reliance on expensive test equipment. Since MATHS simplifies the necessary ATE architecture and design, smaller and lower cost testers can be employed to test the SoC. The system is based on PCIe standards, making it highly portable across all platforms, including ATE, system-level test, board, and in-field testing.
Edinburgh Research Explorer Diabetes and life-long cognitive ability

Objectives : There is a widespread consensus that diabetes impairs cognitive functioning. However, some recent findings have shown that many health conditions generally thought to be detrimental to cognitive functioning are in fact linked to pre-morbid cognitive ability, suggesting reverse causation. To better understand the causality in diabetes-cognition relationship, this study investigates the association of older-age diabetes with concurrent and childhood cognitive functioning. Methods : Lothian Birth Cohort 1936 participants (N = 1,017) completed the same general cognitive ability test at ages 11 and 70 years. Scores were compared between those with and without diabetes at age 70. Diabetes status was based on self-reports and haemoglobin A1c levels. Results : People with diabetes had lower mean cognitive ability scores at ages 11 and 70 when compared with those without diabetes. The effect size was roughly similar at both ages (Cohen’s d ≈ 0.32). When adjusted for age-11 cognitive ability, diabetes status was not associated with cognitive ability at age 70. The association between childhood cognitive ability and older-age diabetes was partly accounted for by body mass index and cholesterol level in older-age. Conclusion : In this sample, diabetes was associated with poorer cognitive ability in old age but this was because of life-long lower cognitive ability in people with diabetes instead of diabetes impairing cognitive functioning.
Multiple Angles of Arrival Estimation Using Broadband Signals and a Nonuniform Planar Array

As the requirements related to resolution or the data rate increase, most angle-of-arrival (AoA) estimation problems can be assumed to be under a broadband signal model. In this paper, AoA estimation using a nonuniform planar array (NUPA), which aims to resolve more signals and reduce mutual coupling, is considered under a broadband signal model. The analysis is conducted in both the space and frequency domains, and a broadband co-array is proposed to improve the performance of the AoA estimation. The broadband co-array is generated as follows: First, the received broadband signal is decomposed into several narrowband signals, and the samples from different frequency bins are transformed to space-domain samples to generate a virtual array. Then, the second-order statistics of the virtual array are used to generate the broadband co-array. The virtual array can decrease the number of element pairs with small interelement spacing to reduce mutual coupling in AoA estimations. With the help of the virtual array, the following broadband co-array can greatly increase the degrees of freedom, resulting in more resolvable signals and lower Cramer-Rao bounds of AoA estimation. An optimization method based on sparse recovery is proposed to locate the array. The simulation results confirm the AoA estimation performance achieved by the designed NUPA.
Low-Cost Reconfigurable 1 bit Millimeter-Wave Array Antenna for Mobile Terminals

A reconfigurable 1 bit millimeter-wave array antenna for mobile terminals is investigated. The reconfigurable array antenna consists of four reconfigurable 1 bit microstrip patch antenna elements. Each patch antenna element is fed by a slot on the ground. The 1 bit patch antenna element with phase values of $-\pi $ and 0 is achieved by selecting the feeding direction of microstrip line. After analyzing the performance of the 1 bit four-element array, a fixed phase is applied to mitigate the negative effects of the 1 bit phase quantized error. The 1 bit four-element arrays with and without the fixed phases are compared in detail. The overlapped −10 dB impedance bandwidth of a prototype array at different beam directions reaches 3 GHz (25–28 GHz). Within the frequency range of 26–28 GHz, the array with the fixed phases can steer the main beam from −34° to 35° without grating lobes. Within these steering beams, the performances of good array gain, moderate sidelobe level, and low cross-polarization level are achieved.
A 0.6V–1.8V Compact Temperature Sensor With 0.24 °C Resolution, ±1.4 °C Inaccuracy and 1.06nJ per Conversion

This paper presents a fully-integrated CMOS temperature sensor for densely-distributed thermal monitoring in systems on chip supporting dynamic voltage and frequency scaling. The sensor front-end exploits a sub-threshold PMOS-based circuit to convert the local temperature into two biasing currents. These are then used to define two oscillation frequencies, whose ratio is proportional to absolute-temperature. Finally, the sensor back-end translates such frequency ratio into the digital temperature code. Thanks to its low-complexity architecture, the proposed design achieves a very compact footprint along with low-power consumption and high accuracy in a wide temperature range. Moreover, thanks to a simple embedded line regulation mechanism, our sensor supports voltage-scalability. The design was prototyped in a 180nm CMOS technology with a 0 <inline-formula> <tex-math notation="LaTeX">$^{\circ }\text{C}\,\,-100\,\,^{\circ }\text{C}$ </tex-math></inline-formula> temperature detection range, a very wide supply voltage operating range from 0.6V up to 1.8V and very small silicon area occupation of just 0.021mm<sup>2</sup>.

Special Session: Testing and Characterization for Large-Scale Programmable Analog Systems

The growth of large-scale analog and mixed-signal configurable computing systems, requires addressing analog and mixed-signal test questions similar to the development of digital IC testing over the past three decades that includes numerous on-chip self-testing mechanisms. End-to-end configurable computing systems require verification using an input sensor or the emulation of an input sensor device and measuring the resulting refined digital, or near digital, output. Verifying and calibrating these configurable systems requires a framework for implementing an application in a once-programmed production devices and general procedure for verifying reconfigurable prototype devices.
Problematic Social Media Use and Conflict, Social Stress, and Cyber-Victimization Among Early Adolescents

An alarming number of early adolescents between the ages of 11 and 14 report experiencing cyber-victimization (i.e., bullying that occurs online or via technology). Although research has demonstrated that spending more time on social media can increase the likelihood of cyber-victimization, less research has examined how adolescents are using social media. For example, the conflicts and problems that can arise from social media use may also increase vulnerability to cybervictimization. The current study examined this association between problematic social media use and conflict (PSMUC) and cyber-victimization among a sample of early adolescents. Also, guided by the Social Information Processing model, the current study examined the indirect effect of social stress (i.e., feelings of isolation and social exclusion) in the association between PSMUC and cyber-victimization. Adolescents (N = 316) participated during the spring of sixth grade from a large public middle school in the Midwestern United States. Assessments included measures of PSMUC, cyber-victimization, and social stress. Using structural equation modeling, results indicated that PSMUC was associated with higher levels of cyber-victimization via higher levels of social stress. These findings indicate that social stress is an important mechanism to consider in the relationship between PSMUC and cyber-victimization experiences among early adolescents. Implications for prevention and intervention programs, as well as future research directions, are discussed.
Sivrikaya, Can: Physical and Mechanical Properties and Decay Resistance of Poplar Modified with mDMDHEU

Chemical modification as a non-biocidal treatment is an effective method to improve physical and biological properties of wood. Poplar is a fast growing species but has poor dimensional stability and durability in addition to low mechanical properties. Low molecular weight Dimethylol dihydroxyethyleneurea (mDMDHEU) was used to improve the properties of poplar mainly dimensional stability and decay resistance. Results indicated high anti-swelling efficiency (ASE), but low variation between both concentrations of mDMDHEU. Tangential swelling was greatly reduced by mDMDHEU treatment during the water immersion period. Untreated poplar samples were severely decayed as compared to modified samples. Modified samples showed lower bending strength unlike to compression strength. Ester peak at 1720 cm-1 revealed chemical reaction between chemical reagent and wood cell wall components. Control samples exhibited considerably higher thermal degradation when compared to the samples modified with mDMDHEU.
A Survey of Cross-Lingual Sentiment Analysis Based on Pre-A Survey of Cross-Lingual Sentiment Analysis Based on Pre-Trained Models Trained Models

With the technology development of natural language processing, many researchers have studied Machine Learning (ML), Deep Learning (DL), monolingual Sentiment Analysis (SA) widely. However, there is not much work on Cross-Lingual SA (CLSA), although it is beneficial when dealing with low resource languages (e.g., Tamil, Malayalam, Hindi, and Arabic). This paper surveys the main challenges and issues of CLSA based on some pre-trained language models and mentions the leading methods to cope with CLSA. In particular, we compare and analyze their pros and cons. Moreover, we summarize the valuable cross-lingual resources and point out the main problems researchers need to solve in the future.
