Effects of Vitamin C Supplementation on the Metabolic Abnormalities Associated with Diabetes Mellitus

Eksojen antioksidan takviyesinin, diyabetin mikro ve makrovasküler komplikasyonlarına karşı faydalı olabileceği bilinmektedir. Bu çalışmada C vitamini desteğinin, diyabetik ratlarda, kronik hiperglisemiye bağlı olarak bozulan insülin sekresyonu, hiperlipidemi, oksidatif stres ve paraoksonaz-1 enzim (PON1) aktivitesi üzerine etkilerinin araştırılması amaçlanmıştır. Bu amaçla, yirmi dört adet Wistar albino cinsi rat C, DC ve DCC grupları olarak 3 gruba ayrıldı. DC ve DCC grubundaki ratlarda, tek doz streptozotosin enjeksiyonu ile diyabet oluşturuldu (45 mg/kg). C ve DC grubundaki ratlar standart rat yemi (C vitamini içermeyen) ile beslenirken, DCC grubundaki ratlar 200 mg/kg dozunda C vitamini ile desteklenmiş deneysel yemle beslendi. Elde edilen bulgulara göre, C grubundaki ratların sekiz haftalık deney süresinin sonunda diyabetik ratlara göre daha az yem ve su tükettiği görüldü (p
Distributed sensor fault detection and isolation for multimachine power systems

This paper presents a distributed sensor fault detection and isolation (FDI) scheme for multimachine power systems. Each generator is interconnected with other generators through a transmission network, where the interactions between directly interconnected generators are nonlinear. In the distributed FDI scheme, a local FDI component is designed for each generator excitation system in the power system based on local measurements and certain communicated information from other FDI components associated with generators that are directly interconnected to the local generator. In each FDI component, adaptive thresholds for distributed FDI are derived, ensuring robustness with respect to nonlinear interconnection and unstructured modeling uncertainty under certain conditions. Furthermore, the fault detectability and isolability properties are investigated, characterizing the class of sensor faults that are detectable and isolable by the distributed FDI method. In addition, the stability and learning capability of the local adaptive fault isolation estimators designed for each generator is derived. A simulation example of a two‐machine power system is used to illustrate the effectiveness of the proposed method. Copyright © 2014 John Wiley & Sons, Ltd.
High temperature and pressure regime soot: Physical, optical and chemical signatures from high explosive detonations

Abstract Submicron particles are formed during the detonation and deflagration of carbon-rich energetic materials known as high explosives (HE) that can be lofted and transported long distances in the atmosphere. Particles include refractory species like soot, a.k. a. black carbon (BC), and have impacts to climate and human health at local, regional, and global scales. Here, we contrast detonation soot aerosol physical, optical and chemical properties that are formed more efficiently in terms of emission factors and ratios with traditional combustion sources from biomass burning and fossil fuels. We utilize ambient aerosol techniques for the first time to identify soot from two well-known HE's (1) Comp B-3: 40% trinitrotoluene (TNT) and 60% 1,3,5-trinitro-1,3,5-triazinane (RDX) and (2) PBX 9501: 95% 1,3,5,7-tetranitro-1,3,5,7-tetrazoctane (HMX) with 2.5% Estane and a 2.5% mixture of bis(2,2-dinitropropyl)-acetal (BDNPA) and bis(2,2-dinitropropyl)-formal (BDNPF). Size distributions, optical and chemical properties are presented. Aggregate soot had small mobility diameters (<100 nm) and unique optical and chemical signatures depending on the explosive composite composition, detonation atmosphere (e.g., air, argon) and pressure. Single-scattering albedos (SSA) from 0.3 to 0.8 and absorption Angstrom exponents (AAE) from 0.5 to 2.0 measured across 405–870 nm wavelengths depended on the explosive composite composition and detonation conditions. Comp B-3 detonation soot was similar to other combustion soot sources, whereas PBX 9501 soot had high scattering relative to absorption. Carbonaceous chemical signatures included the presence of fullerenes that were distinct from ambient and laboratory-generated soot surrogates and the detection of trace metals, including aluminum, copper, iron, and zinc.
Attention Allocation and Heterogenous Consumption Responses

Recessions often have detrimental eﬀects on both employment and equity returns, forcing individuals to make decisions about how to balance risks to their labor and capital income. In this paper, we study how individuals allocate their limited attention between capital income and labor income risks in a two-period consumption-saving model with recursive utility. Speciﬁcally, we examine how the optimal attention and consumption-saving decisions are inﬂuenced by individuals’ attention capacity, wealth endowments, income risks, and preferences for risk and time. We show that our model can generate results that are consistent with several novel facts regarding how diﬀerences in individuals’ wealth levels and beliefs about their unemployment risks inﬂuenced their consumption during the Great Recession. Furthermore, we ﬁnd that the welfare loss due to limited attention is signiﬁcantly larger for households with lower wealth; allowing these households to ﬂexibly allocate their attention can signiﬁcantly reduce this welfare loss.

Low-Dose Ketamine as Perioperative Analgesia in Caesarean Sections in Remote Areas with Limited Medical Supplies

Introduction: Cesarean section is the most common surgical procedure performed in the world and its postoperative pain is still a major issue in several countries. In a low-resource setting, this management poses a challenge for anesthesiologists. Ketamine is the most used anesthetic drug in the world due to its easy access and proven benefits. Objective: This research aims to analyze the effectiveness of low-dose ketamine as postoperative analgesia in cesarean sections conducted in areas with limited medical supplies. Materials and Methods: A Randomized Controlled Trial (RCT) was done from August 2020 to January 2021 with consenting pregnant patients who had undergone cesarean section. The sampled population was randomized to receive either ketamine intravenously or a placebo before the Subarachnoid Block (SAB). Low dose ketamine was divided into three groups 0.15 mg/kg, 0.25 mg/kg, and 0.5 mg/kg. The outcome was divided into primary outcome (pain score after 1-hour post-operation, 2 hours post-operation, 24 hours post-operation, and 48 hours post-operation) and secondary outcome (Apgar Score in the first minute and 5 minutes, hypotension after SAB, sedative effect during operation, postoperative nausea vomiting, time to receive opioid postoperative as rescue analgesia and total opioid uses). Results and Discussion: This study screened 105 patients and recruited 90 patients that were randomized into two groups consisting of 45 patients that received either low-dose ketamine or a placebo. The groups administered ketamine showed a lower pain score in 1 hour (p-value = 0.0037) and 2 hours post-operation (p-value = 0.0037). They also showed that it could prolong the administration of fentanyl (p-value = 0.0003) and lower total fentanyl used (p-value = 0.0008). The groups administered ketamine showed that there was a sedation effect (p-value = 0.0001) that depended on the dosage used. Conclusion: Intravenous ketamine with low doses can reduce pain scores at 1 hour to 2 hours post-operation and shows the need to reduce opioid requirements.
Self-Sustained Rigid Fully Metallic Metasurfaces to Enhance Gain of Shortened Horn Antennas

This article presents mechanically robust, low-cost, lightweight, and polarization-independent metallic metasurfaces (MMs) to enhance the gain and directivity of shortened horn antennas. The MM was designed based on the strategy of correcting the actual phase errors probed on the aperture of the horn using the near-field phase-transformation principle. The fundamental unit cell of the MM is made of a pair of cross slots created in a monolithic thin conductive sheet and is entirely free from high-cost dielectrics. The lack of dielectrics makes MM lightweight, cost-efficient and easy to fabricate the prototype for mass production. The MM has a 2D array of unit cells arranged to increase the gain of the shortened horn by improving aperture efficiency through local phase transformation in a wide frequency band. The concept is demonstrated by designing MMs for shortened horns with different heights and the same physical aperture at the center operating frequency of 12.5 GHz. The maximum gain-bandwidth with MM is achieved for the shortest horn, which is validated by measuring the physical prototype. The results indicate that horn gain with MM increases by 9.2 dB (from 11.1 to 20.3 dBi) and has a 3-dB fractional gain-bandwidth of 10.4%. The weighted density of the fabricated MM is only 0.87 g/cm2. Including MM, the total antenna height is around 61% shorter than a conventional air-filled horn having a similar peak gain.
Online Divorce Education: Learning from Participants Who Want More

Divorce education is designed for divorcing parents with minor children, and in a growing number of states, participation has become court-mandated to finalize a divorce. To increase accessibility, some states have adopted brief, online formats for divorce education programming. Evaluations are encouraging; however, less is known about how opinions on course length relate to participants’ views on the benefits of their participation. This study analyzed qualitative data from parents (n = 41) who thought their mandated divorce education course was too short. Results indicate that participants thought the course increased their knowledge of divorce-related matters. They also suggested improvements related to course content priorities. These findings may inform Extension specialists, family life practitioners, and program planners working to improve the delivery of online divorce education programs.
Cephalosporin as Potent Urease and Tyrosinase Inhibitor: Exploration through Enzyme Inhibition, Kinetic Mechanism, and Molecular Docking Studies

In present study, eleven cephalosporin drugs were selected to explore their new medically important enzyme targets with inherited safety advantage. To this end, selected drugs with active ingredient, cefpodoxime proxetil, ceftazidime, cefepime, ceftriaxone sodium, cefaclor, cefotaxime sodium, cefixime trihydrate, cephalexin, cefadroxil, cephradine, and cefuroxime, were evaluated and found to have significant activity against urease (IC50 = 0.06 ± 0.004 to 0.37 ± 0.046 mM) and tyrosinase (IC50 = 0.01 ± 0.0005 to 0.12 ± 0.017 mM) enzymes. Urease activity was lower than standard thiourea; however, tyrosinase activity of all drugs outperforms (ranging 6 to 18 times) the positive control: hydroquinone (IC50 = 0.18 ± 0.02 mM). Moreover, the kinetic analysis of the most active drugs, ceftriaxone sodium and cefotaxime sodium, revealed that they bind irreversibly with both the enzymes; however, their mode of action was competitive for urease and mixed-type, preferentially competitive for tyrosinase enzyme. Like in vitro activity, ceftriaxone sodium and cefotaxime sodium docking analysis showed their considerable binding affinity and significant interactions with both urease and tyrosinase enzymes sufficient for downstream signaling responsible for observed enzyme inhibition in vitro, purposing them as potent candidates to control enzyme-rooted obstructions in future.
Comparison of Nutritive Value in Fodder Species and Industrial By-products Available in Anuradhapura

: This experiment intended to ﬁgure out the nutritive value of fodder species and industrial by-products for feeding ruminants in Anuradhpura. Fodder species; maize ( ), sorghum ( gliricidia ( ), guinea and agro-industrial by-products; rice ( poonac, maize ( ) meal and soya bean ( ) meal (SBM) were Zea mays Glycine max analyzed for proximate composition, acid detergent ﬁber (ADF), neutral detergent ﬁber (NDF) and gross energy (GE). Nitrogen free extract (NFE), total digestible nutrients (TDN) and metabolizable energy (ME) were calculated. The data were analyzed using the one-way ANOVA procedure in SAS. The observed TDN, ME and GE of fodder species di ered signiﬁcantly (p<0.05). The highest (p<0.05) values of ff dry matter (DM), crude fat(EE), crude protein (CP), TDN, GE and ME were obtained for gliricidia. Guinea grass contained the highest (p<0.05) ADF and NDF contents compared to other fodder species. Sorghum and CO3 showed the highest (p<0.05) ash and crude ﬁber (CF) while the lowest (p<0.05) ash and CF were recorded in maize and gliricidia. DM not signiﬁcantly di ered (p>0.05) in agro-industrial by- The was ff products. The highest (p<0.05) total ash, CP, TDN and MEwere reported in SBM while NFE was highest in maize meal. The highest (p<0.05) values of EE and GE contents were obtained for rice bran. The nutrient content observed in the feed ingredients in the present study, is in par with other references. According to the nutrient composition, these feed ingredients can be used for feeding ruminants and in the formulation of total mixed rations for dairy cows inAnuradhapura.
Iron and Folic Acid Supplementation in Pregnancy: Findings from the Baseline Assessment of a Maternal Nutrition Service Programme in Bangladesh

Effective coverage of antenatal iron and folic acid (IFA) supplementation is important to prevent adverse maternal and newborn health outcomes. We interviewed 2572 women from two rural districts in Bangladesh who had a live birth in the preceding six months. We analysed the number of IFA tablets received and consumed during pregnancy and examined the factors influencing IFA consumption by multiple linear regression and user adherence-adjusted effective coverage of IFA (consuming ≥180 IFA tablets) by Poisson regression. Overall, about 80% of women consumed IFA supplements in any quantity. About 76% of women received antenatal care at least once, only 8% received ≥180 IFA tablets, and 6% had user adherence-adjusted coverage of antenatal IFA supplementation. Multivariable analysis showed a linear relationship between the number of antenatal care (ANC) visits and the number of IFA supplements consumed, which was modified by the timing of the first ANC visit. Women’s education, free IFA, and advice on IFA were also associated with higher IFA consumption. Interventions targeting at least eight ANC contacts, starting early in pregnancy, providing advice on the importance of IFA, and providing IFA supplements in higher quantity at ANC contacts are likely to increase effective coverage of antenatal IFA supplementation.
Evaluation of a Health Education Intervention for Rural Preschool and Kindergarten Children in the Southeastern United States: A Cluster Randomized Trial

This research employed a matched-pairs randomized field experiment design to evaluate a classroom-based health education intervention for pre-Kindergarten and Kindergarten children in a rural region of the southeastern United States. Schools were matched on demographic characteristics, then one school from each pair was randomly assigned to the treatment group and one to the delayed treatment group. The intervention included a field trip experience and an integrated curriculum designed to increase knowledge about nutrition, physical activity, and sleep. Staff conducted individual assessments of changes in knowledge with a random sample of children from each classroom (252 children from treatment classrooms; 251 children from delayed treatment classrooms). We used a multilevel linear regression with maximum likelihood estimation to incorporate the effects of clustering at the classroom and school level while examining the effects of the intervention on individual assessment change scores. During the intervention period, an estimated 3,196 children (treatment: 1,348 students in 68 classrooms in 10 schools; delayed treatment: 1,848 students in 86 classrooms in 10 schools) participated in the intervention. Children in the treatment group had significantly larger assessment change scores than children in the delayed treatment group. Findings suggest significant beneficial effects of the intervention on health knowledge.
Seasonal Differences in Expression of Neuropeptide Y (NPY) in Visual Centers of Spotted Munia (Lonchura punctulata)

The visual perception of birds is an incredibly exciting subject of research. Birds have significantly higher visual acuity than most other animals, which helps them stay safe in flight and detect their prey. Understanding how the eyes send information to the brain for additional processing is crucial. The brain has sections (nuclei) that accept input from the retina. The key areas where information is processed are the hyperpallium apicale (HA), hippocampus (HP), optic tectum (TeO), nucleus rotundus (RoT), and the geniculatus lateralis ventralis (Glv); among these, the RoT is one of the most investigated nuclei for vision. This study looked at how the visual centers of non-photoperiodic songbirds (Spotted Munia) adapt in different life history stages by looking at NPY expression. We immunohistochemically quantified NPY expression in four different seasons, including pre-breeding (June), breeding (September), post-breeding (December), and regressed (March) in the brain of Spotted Munia. We evaluated changes in the expression levels of the peptide throughout the year, by determining the expression at four different periods throughout the year. Peptide expression levels were projected to fluctuate within photoperiod-induced seasons. It was discovered that the parts of the brain related to vision (RoT, HA, and HP) have a higher number of immunoreactive cells during their mating season, i.e., during the summer. The appearance of NPY, a non-photic marker, in brain areas linked with light perception, was fascinating. Indirectly, NPY aids avian reproduction in a variety of ways. These findings demonstrate the importance of these nuclei in the process of reproduction, as well as the involvement of NPY in the visual brain areas of Spotted Munia.
Comparing Nonresponders and Responders of Online Intercept Surveys: A Large-Scale Experimental ICT Security-Related Study

Online surveys have become a popular way to collect data. However, response rates are low, specifically for online intercept-based surveys, which can be as low as 1%. This raises questions about the accuracy of the inferences based on these results. Furthermore, it is difficult to compare the characteristics and behavior of the responders and nonresponders as there is very limited information on nonresponders. The objective of this article is to present a unique comparison of online intercept survey responders, nonresponders, and partial responders. The sample includes 192,566 U.S.-based users who went through a research experiment during the installation process of ESET online security software. During the process, users were asked to enable or disable the detection of potentially unwanted applications. At the end, they could also opt to answer questions on a short security-related survey. The users were split into three groups: (a) nonresponders ( n = 184,010 ), (b) complete responders ( n = 6,750 ), and (c) partial responders ( n = 1,806 ). There were only slight differences between the responder and nonresponder groups in their hardware (i.e., computer CPU quality and RAM size). Responders and nonresponders differed in their behavior. Complete responders enabled the detection of potentially unwanted applications significantly more often than nonresponders (on average by 4.5%) and spent more time on the screen that provided details about this feature. Additional comparisons showed that complete responders were slightly younger and more educated than partial responders. We conclude that there are only slight differences between online intercept survey responders and nonresponders and that these differences manifest in computer usage-related decisions. Despite the low overall response rates, online product-related surveys can provide useful insights about the user base. Nevertheless, the companies that use online surveys should be careful because behavior might differ for users in specific situations.
Task-based language assessment: a compatible approach to assess the efficacy of task-based language teaching vs. present, practice, produce

Abstract Task-Based Language Teaching has been developed in response to the teacher-dominated, focus-on-forms methods such as Present, Practice, Produce (PPP). The body of literature is replete with studies examining the learning efficacy of the PPP approach versus TBLT; however, these studies did not use assessment tasks in comparing these two methods. To this end, the present study used an Assessment Task, a Grammaticality Judgment Test (GJT), and an Elicited Imitation Test (EIT) to compare the efficacy of PPP versus TBLT. Thirty-four lower-intermediate English language learners in Iran were randomly assigned to TBLT, PPP, and Control groups. The study results revealed that the performance of TBLT and PPP on the GJT and EIT significantly improved from pre-assessment to post-assessment, while the Control group did not show any significant improvements on any of the tests. Results indicated that only the TBLT group made substantial improvements in TBLA in the post-assessment, while the PPP and Control groups’ performance did not significantly improve.
RhoA with Associated TRAb or FT3 in the Diagnosis and Prediction of Graves' Ophthalmopathy

During Graves' disease (GD) treatment, Graves' ophthalmopathy (GO) is often ignored because only mild ocular symptoms are present in early GD. Therefore, we performed isobaric tags for relative and absolute quantification (iTRAQ) analysis and measured relevant endocrine hormones to identify predisposing factors of GO. Serum samples from 3 patients with mild GD and GO and 3 patients with GD but without GO were analyzed by iTRAQ. Based on their clinical data, 60 patients with GD were divided into the GO-free and GO groups. All patients were followed up for 7 months. Their eye conditions and changes in related biochemical indexes were recorded. The iTRAQ results showed that RhoA expression was upregulated and correlated significantly with the tight junction pathway and immunity. The changes in FT3 and RhoA from baseline to 7 months, the FT3 and RhoA baseline levels, and the TRAb titer levels in patients with GD significantly differed between the groups. ELISA and western blotting for RhoA, TRAb, and FT3 in the serum samples from GO patients showed significant upregulation, as well as elevated serum RhoA and TRAb levels in the mild stage of GO. At 7 months, the serum RhoA and FT3 levels were elevated. RhoA is a potential biomarker for mild GO. In GD patients, if an elevated serum RhoA level is accompanied by an elevated TRAb or FT3 level, GO is highly likely to occur, even when obvious ocular symptoms are absent.
