Role of Alpha Lipoic Acid and Cocoa in Prevention of Metabolic Changes Induced by Fructose in Adult Male Albino Rats = دور حامض الألفا ليبويك والكاكاو في منع التغيرات الأيضية التى يتسبب فيها الفركتوز في ذكور الجرذان البيضاء البالغة

Background: Obesity is one of the most critical threat to health and well-being. It contributes to elevated risk of cardiovascular diseases and diabetes mellitus . Objective: Investigation of the possible role of some natural antioxidants alpha lipoic acid [α-LA] and cocoa in prevention of metabolic changes induced by fructose rich water in adult male albino rats. Materials and methods: The current study has been carried on 50 adult male albino rats of average weights 130-160 g. They were divided into five equal groups: Group I (Control group), Group II (10 % fructose rich water "FRW"- fed group), Group III (FRW-fed group received 35 mg/kg α-LA) three times / week, Group IV (FRW-fed group received 1 g/Kg cocoa 5 times / week), and Group V (FRW-fed group received both α-LA and cocoa). All rats were subjected to measurement of body weight (B.W) weekly, oral glucose tolerance test (OGTT), estimation of triglycerides “TAG”, total cholesterol “TC”, low density lipoprotein-cholesterol “LDL-c”, high density lipoprotein-cholesterol “HDL-c”, malondialdehyde (MDA), plasma level of catalase (CAT) activity and plasminogen activator inhibitor-1 (PAI-1). Abdominal adipose tissue (AAT) was dissected and weighed. Liver and abdominal adipose tissue were histopathologically examined. Results: FRW-fed rats showed significant increase in BW, AAT weight, TC, LDL-c, TAG, MDA, OGTT at 0, 30, 60 and 120 min., PAI-1 and number of vacuolated hepatocytes, significant decrease in CAT activity and adipocytes number, and insignificant decrease in HDL-c.FRW fed rat receiving α-LA showed significant increase in BW, AAT weight and number of vacuolated hepatocytes, insignificant increase in lipid profile, CAT activity, MDA, PAI-1 and OGTT at 30 and 60 min., significant decrease in OGTT at 0 level and adipocytes number, and insignificant decrease in OGTT at 120 min. FRW fed rat received cocoa powder (group IV) showed significant increase in CAT activity, MDA and number of vacuolated hepatocytes, insignificant increase in BW, AAT weight, total cholesterol, LDL-c, HDL-c PAI-1, OGTT at 30 and 60 min. and adipocytes number, significant decrease in OGTT at 0 and 120 min., and insignificant decrease in TAG. Conclusion: Alpha lipoic acid and/or cocoa administration ameliorated the metabolic and oxidative stress changes. Co-administration of α-LA and cocoa produced non-significant effect over individual administration except in reducing serum LDL-c and increasing plasma CAT activity. Cocoa alone tended to be more effective in reducing body weight, AAT weight, adipocyte size, improving CAT and glucose tolerance than α-LA alone, while α-LA alone tended to reduce MDA to level insignificantly changed from control.
Mesoporous Semiconductors: A New Model To Assess Accessible Surface Area and Increased Photocatalytic Activity?

Mesoporous photocatalysts have gained tremendous attention in the past decade by demonstrating that increased surface area and porosity can strongly improve their performance. In fact, all reports on mesoporous semiconductors corroborate this scenario. But is it possible to quantify and compare the reported advantages of the mesopores and the increased surface area between different works? In this contribution, we present a model that can evaluate the improvements in photocatalytic activity achieved by the introduction of mesoporosity independent of synthetic or test conditions. We exemplify this methodology focusing on photocatalytic hydrogen/oxygen evolution with sacrificial reagents, but also include examples of CO2 reduction and electrocatalysis. By correlating the relative increase in surface area to the relative increase in activity—in comparison to non-porous counterparts—we show that the origin of mesoporosity can have a pronounced influence on the activity enhancement and that different semicondu.

The decline in national sugar cane production from 2015 amounted to 2.4 million tons and in 2016 amounted to 2.2 million tons. One of the reason for the decline in sugar cane production is the proportion of Ratoon Cane (RC) which is relatively high compared to Plant Cane (PC). The objective of the study is to analyze the technical efficiency of farming between plant cane (PC) and ratoon cane (RC). The method used in sampling farmer households is purposive by considering there is no sampling frame available in the study area. Data analysis method using the stochastic frontier production function model. The results showed that the plant cane farming (PC) was more technically efficient than ratoon cane (RC) with an average value of PC sugarcane technical efficiency of 93 percent and an average sugarcane technical efficiency of RS by 89 percent.
Synergistic Effect of Silica Nanoparticles and Rhamnolipid on Wettability Alteration of Low Permeability Sandstone Rocks

Wettability modification is one of the main mechanisms to increase oil recovery from low-permeability oil reservoirs. Nanofluids composed of nanoparticles can be used as modifiers to alter wettability from oil-wet to water-wet condition thus to promote hydrocarbon recovery. Biosurfactants, which are candidates to replace synthetic surfactants for industrial applications, have the potential to prepare nanofluids. In this study, nanofluids prepared by dispersing SiO2 nanoparticles in rhamnolipid solution (hereby named bionanofluids) were considered potential wettability modifiers to apply to petroleum recovery from low-permeability sandstone reservoirs. Analyses via visual observation, optical absorbance measurement, ζ-potential determination, and particle size measurements demonstrated that the bionanofluids with 25 ppm rhamnolipids maintained an optimal stability. The effect of bionanofluids on wettability alteration was investigated through contact angle measurement and imbibition test. The results showe.
Poor College Students’ Resilience Phase in Online Learning during the Covid-19 Pandemic

Abstract : After a year of the Covid-19 pandemic, online learning remains to be carried out in Indonesia. In this situation, college students have to survive with excellent resilience amid various restraints. This study investigates the poor college students’ resilience phase in online learning during the Covid-19 pandemic. With the qualitative inquiry narrative method, this study involved 30 college students from Universitas Mulawarman as the participants. The participants were selected through the purposive sampling technique and interviewed via phone call. The analysis process was carried out using the induction and deduction process, while the analysis was completed based on the field data and referred to the theory in the deduction process. The research results show that college students experience three resilience phases in online learning: survival, adaptation, and recovery. The survival stage occurs in the initial months of online learning, while the adaptation phase occurs in the first six months of online learning. From the tenths month of online learning, students have reached the recovery stage. Following this research finding, guidance and counseling services in the universities are required to facilitate poor students to enhance their survivability during this pandemic.

Gender Disparities in Cardiovascular Health Metrics among Rural-Dwelling Older Adults in China: a population-based study

Background: Cardiovascular health (CVH) metrics among Chinese older adults are poorly understood. We investigated gender disparities in CVH metrics and their management among rural-dwelling older adults in China.Methods: This community-based study included 5026 participants (age ≥65 years; 57.2% women) in the baseline survey of a multimodal intervention study in rural China. Data were collected through face-to-face interviews, clinical examinations, and laboratory tests in March-September 2018. We defined six CVH metrics (three behavioral factors—smoking, body mass index, and physical activity; three biological factors—blood pressure, total cholesterol, and blood glucose) following the modified American Heart Association’s recommendations. We performed descriptive analysis separately for men and women.Results: Of all participants, only 0.8% achieved ideal levels in all six CVH metrics. Men were more likely than women to have ideal levels in all CVH metrics but smoking. Women had higher prevalence of ideal global CVH metrics (9.7% in women vs. 7.8% in men) and behavioral CVH metrics (18.3% vs. 9.5%) (p<0.001), whereas men had higher prevalence of ideal biological CVH metrics (5.4% in men vs. 3.5% in women, p<0.001). The prevalence of ideal global and behavioral CVH metrics increased with age in both women and men (p for trend<0.001). Women were more likely to be aware of their hypertension and diabetes, and to receive antihypertensive treatment, while men were more likely to achieve the goal of high cholesterol treatment (p<0.05). Conclusions: The CVH metrics among older adults living in the rural communities in China are characterized by an extremely low proportion of optimal global CVH metrics and distinct gender differences, alongside poor management of major biological risk factors.Trial registration: ChiCTR1800017758.
An ordered mesoporous silica framework based electrolyte with nanowetted interfaces for solid-state lithium batteries

The practical applications of lithium metal as an anode material are hindered by the uncontrollable growth of lithium dendrites. Herein, an ordered mesoporous silica framework (MCM-41) based solid-state electrolyte (Li-IL@MCM-41 SSE) with nanoconfined ionic liquids is prepared through a post-impregnation method. The as-prepared electrolyte with nanowetted interfaces demonstrates suppression towards lithium dendrites, high thermal stability (up to 350 °C) and excellent electrochemical properties, such as high ionic conductivity (3.98 × 10−4 S cm−1 at 30 °C), a broad electrochemical potential window (up to 5.2 V) and good compatibility with different electroactive materials. The solid-state batteries (SSBs) assembled exhibited excellent cycling performance, delivering capacities of 138 mA h g−1, 127 mA h g−1 and 163 mA h g−1 after 100 cycles at room temperature with LiFePO4, LiCoO2, and LiNi0.8Co0. 1Mn0.1O2 cathode materials, respectively. The good battery performance can be ascribed to the effective three-dimensional ion-conducting networks established by the nanowetted interfaces. The aforementioned results exhibit the good prospects of the Li-IL@MCM-41 SSE for application in lithium metal batteries.
Dynamics of Health Technology Diffusion in Integrated Care System (DHTDICS): A Development and Validation Study

Background: Limited diffusion and utilization of health technology have greatly halted the improvement of resource integration and healthcare outcomes. However, the dynamic mechanism of health technology diffusion in the context of the integrated care system (ICS) remained largely unknown. The purpose of this study is to develop and validate the scale on Dynamics of Health Technology Diffusion in Integrated Care System (DHTDICS) for providing instruments to investigate the health technology diffusion in the ICS. Methods: The scale with 39 items was initially designed on the basis of the proposed model developed from previous research. And it was validated in a cross-sectional questionnaire survey including 246 participants. Exploratory factor analysis was used to assess domains in the questionnaire, and analyzed correlation, factorials, internal consistency and validity of the questionnaire. In addition, structural equation modeling was performed to determine the total effects of each domain on the health technology diffusion in the ICS.Results: Reliability analysis revealed excellent internal consistency, as the value of Cronbach’s alpha greater than 0.80 for all of the four DHTDICS domains in this study. An acceptable validity was confirmed through tests of construct validity, convergent validity and discriminant validity. With respect to the potential domains and dimensions that DHTDICS contributes, the results highlight the existence of 4 domains: personal beliefs, technical drivers, organizational readiness, and external environment. Among them, the impact on health technology diffusion is, in descending order, organizational readiness, personal beliefs, external environment, and technical drivers.Conclusions: The findings of this study support the validity of the DHTDICS, and will be a helpful reference for developing future intervention strategies to promote health technology diffusion in the ICS.
Role of the foliar fertilization treatments on quality attributes of sweet cherry fruits (Prunus avium)

This study was carried out in a cherry in 2017 in Susehri, Sivas. Eight -years old “0900 Ziraat” sweet cherry trees grafted on MaxMa 14 rootstocks were used as the plant material of the study. In the study, per 100 liters of water 250 gram of Azro select, a foliar fertilizer which contains 35% potassium and 5% nitrogen, and per 100 liters of water 200 gram of Zinc salt (Zinc Sulphate Hepta Hydrate) foliar fertilizer, which contains 22 % Zinc, were applied. The treatment was done twice: first, at the end of blooming, second, 15 days after the first treatment. As a result of the study, fruit weight, size, fruit firmness, SSC and vitamin C values of fruits obtained from potassium treated trees were significantly higher whereas fruit color values were lower. However, the effect of potassium on the titratable acidity values was not significant. With zinc application, while statistically significant increase in the fruit size, SSC and vitamin C values have not occurred, the highest values in terms of flesh firmness, fruit color and titratable acidity were recorded in the sweet cherries treated with zinc. The combination of zinc and potassium led to an increase in fruit weight, fruit size, SSC and titratable acidity, and decrease in vitamin C and color values.
First determination of anticancer, cytotoxic, and in silico ADME evaluation of secondary metabolites of endemic Astragalus leucothrix Freyn & Bornm

Isolation and characterization of anticancer activity guided secondary metabolites of endemic Astragalus leucothrix Freyn& Bornm were aimed. Aerial parts of the plant were extracted by maceration method in the solvent system methanol-chloroform (1 : 1) at room temperature. The obtained crude extract was dissolved in purified water. Then, the extract was partitioned with n-hexane, chloroform, ethyl acetate, and n-butanol, respectively. Anticancer activity tests of all the fractions were performed against HeLa and C6 cancer cells. The chloroform fraction that has highest anticancer activity was subjected to chromatographic methods such as column chromatography and thin layer chromatography. Pentyl tetratetracontanoate (1), alfalone (2), 3,6,8-tribromoquinoline (3), and 3,6,8-tribromochromenium (4) molecules were detected from this plant for the first time. The structure determinations of the isolated molecules were elucidated by methods such as 1D and 2D NMR, HPLC - TOF / MS, and GC - MS analysis. Finally, anticancer and cytotoxic activity tests of the compounds were performed. Literature review showed that 3,6,8-tribromochromenium is a new compound. IC50 values of compound 1–2 and compound 3–4 mix were determined to be 4.50 ± 0.10, 2.81 ± 0.00, 4.33 ± 0.00 μM against C6 cell, respectively. The drug likeness properties of 1–4 were obtained by SwissADME. According to Lipinski’s rule of five; 2–4 could be a new potential anticancer agent.
Chapter 8 Flux-Periodicity Crossover from hc / e in Normal Metallic to hc / 2 e in Superconducting Loops

One of the most important properties of superconductors is their perfectly diamagnetic response to an external magnetic field, the Meissner-Ochsenfeld effect. It is a pure quantum effect and therefore reveals the existence of a macroscopic quantum state with a pair condensate. A special manifestation of the diamagnetic response is observed for superconducting rings threaded by a magnetic flux: flux quantization and a periodic current response.
RUNNING HEAD: Changes after Home-Start Long-term Changes in Parenting and Child Behaviour after the Home-Start Family Support Program

Background The intervention Home-Start is a wide spread program in a number of countries, among which the Netherlands. In Home-Start, trained volunteers visit families with young children in need of support once or twice a week to help them to deal with problems in family life and parenting. Little is known, however, about the effects of Home-Start. This study describes shortterm and long term changes in families that participated in Home-Start. Methods ‘Three groups of families with young children (at the start mean age 1 1⁄2 years) were followed over a period of four years. One of the groups of families participated in the Home-Start family support program in the first 6,6 months of this period. The two other groups were (1) a randomly selected community sample and (2) a group of families with elevated parenting stress and a need for support. Data were collected at the beginning of the study, (after median 1.4 months), directly after the intervention (median 6.6 months) and at two follow-up occasions (respectively, median 12.5 and 49.2 months after the first measurement). At the last measurement, data were available for 33, 45 and 34 families respectively. ’ Results Multilevel analysis showed more positive changes in parental wellbeing, competence and behaviour (more consistent behaviour and less rejection) during the intervention period in the Home-Start group than in the two other groups. At the three year follow up, the Home-Start group showed, compared to the other groups, more improvements in parenting (more responsiveness), but also diminished child externalizing and internalizing behaviour problems (less oppositional defiant behaviour, affective problems and anxiety problems). Conclusions. Home-Start seems a promising family support intervention that deserves to be studied more extensively.
Elaboration and Characterization of Active Apple Starch Films Incorporated with Ellagic Acid

Apple starch films were obtained from apples harvested at 60, 70, 80 and 90 days after full bloom (DAFB). Mechanical properties and water vapor permeability (WVP) were evaluated. The apple starch films at 70 DAFB presented higher values in the variables of tensile strength (8.12 MPa), elastic modulus (3.10 MPa) and lower values of water vapor permeability (6.77 × 10−11 g m−1 s−1 Pa−1) than apple starch films from apples harvested at 60, 80 and 90 DAFB. Therefore, these films were chosen to continue the study incorporating ellagic acid (EA). The EA was added at three concentrations [0.02% (FILM-EA0.02%), 0.05% (FILM-EA0.05%) and 0.1% (FILM-EA0.1%) w/w] and compared with the apple starch films without EA (FILM-Control). The films were characterized by their physicochemical, optical, morphological and mechanical properties. Their thermal stability and antioxidant capacity were also evaluated. The FILM-Control and FILM-EA0.02% showed a uniform surface, while FILM-EA0.05% and FILM-EA0.1% showed a rough surface and insoluble EA particles. Compared to FILM-Control, EA modified the values of tensile strength, elasticity modulus and elongation at break. The antioxidant capacity increased as EA concentration did. EA incorporation allowed obtaining films with higher antioxidant capacity, capable of blocking UV light with better mechanical properties than film without EA.
Synthesis, Isolation, and Properties of All Head-to-Tail Cyclic Poly(3-hexylthiophene): Fully Delocalized Exciton over the Defect-Free Ring Polymer

The synthesis of defect-free cyclic poly(3-hexylthiophene) (P3HT) was achieved for the first time by the GRIM polymerization using an appropriate initiator, cyclization by a Pd-mediated end-to-end coupling reaction, and two isolation processes using functionalized resins by selective capture of the impurities by taking advantage of the discriminable end groups. Various properties were investigated for defect-free linear and cyclic P3HT with all head-to-tail couplings as well as those with inverted 3-hexylthiophene units formed through the conventional GRIM polymerization. Mn,SEC, Mw,SEC, Rh, and [η] were significantly smaller for cyclic P3HT, and the topologies were visualized by STM. Remarkably, fluorescence spectroscopy revealed the essentially forbidden 0–0 transition with an extended lifetime for the defect-free cyclic P3HT arising from the circular symmetry, while cyclic P3HT with inverted units showed a strong 0–0 transition, which was similar to linear P3HT, due to the defects causing the symmetry .
The Students’ Perceptions on Using Blended Learning for English Learning during Covid-19 Pandemic

The policy of remote learning (PJJ) during the COVID-19 pandemic caused new problems for the students. The Implementation of the teaching and learning process has totally changed from face-to-face into online learning and some schools tried to integrate offline and online learning. This research objective was to see the students’ perception of the use of blended learning in English classes. The Subject of this study is Mechanical Engineering Students 4th Semester of STTR Cepu. This study uses a descriptive quantitative design. The researcher took data from a questionnaire on the students' perceptions in the use of blended learning which was consisted of 19 questions and an observation checklist to crosscheck the students’ answers in the questionnaire. Then, analyzing the data descriptively and measuring it using a Likert scale. The results of the study showed the students’ positive response toward the implementation of blended learning since it has great benefit in the teaching and learning process. The implementation of the blended learning method in English lessons required the teachers’ creativity in providing an English learning platform. This research also revealed the weaknesses of Blended Learning. The success of the implementation of blended learning depended on the availability of the facilities like internet access and network in applying that method. In addition, the knowledge of using technology was necessarily mastered by the teachers and the students.
