Acid/Base-Triggered Photophysical and Chiroptical Switching in a Series of Helicenoid Compounds

A series of molecules that possess two quinolines, benzoquinolines, or phenanthrolines connected in a chiral fashion by a biaryl junction along with their water-soluble derivatives was developed and characterized. The influence of the structure on the basicity of the nitrogen atoms in two heterocycles was examined and the photophysical and chiroptical switching activity of the compounds upon protonation was studied both experimentally and computationally. The results demonstrated that changes in the electronic structure of the protonated vs. neutral species, promoting a bathochromic shift of dominant electronic transitions and alternation of their character from π-to-π* to charge-transfer-type, when additionally accompanied by the high structural flexibility of a system, leading to changes in conformational preferences upon proton binding, produce particularly pronounced modifications of the spectral properties in acidic medium. The latter combined with reversibility of the read-out make some of the molecules in this series very promising multifunctional pH probes.
Usnea aurantiaco-atra (Jacq) Bory: Metabolites and Biological Activities

Background: Lichens are complex symbiotic associations between a fungus and an alga or cyanobacterium. Due to their great adaptability to the environment, they have managed to colonize many terrestrial habitats, presenting a worldwide distribution from the poles to the tropical regions and from the plains to the highest mountains. In the flora of the Antarctic region, lichens stand out due to their variety and development and are a potential source of new bioactive compounds. Methods: A phytochemical study of the Antarctic lichen Usnea aurantiaco-atra (Jacq) Bory was conducted with the intention of determining the most important metabolites. In addition, the cytotoxic and antioxidant activities of its extracts were determined. Results: Cytotoxicity studies revealed that the hexane extract contains usnic acid as a majority metabolite, in addition to linoleic acid, ergosterols and terpenes, and demonstrates cytotoxic activity against an A375 melanoma cell line. On the other hand, the presence of total phenols in the extracts did not influence their antioxidant activity. Conclusions: U. aurantiaco-atra contains mainly usnic acid, although there are terpenes and ergosta compounds that could be responsible for its cytotoxic activity. The presence of phenols did not confer antioxidant properties.
Fracture Resistance of Roots Obturated with Bioceramic and Epoxy Resin- Root Canal Sealers Using Different Obturation Techniques: An Ex-vivo study.

Aim: The aim of this study was to compare the fracture resistance of endodontically treated teeth obturated with two root canal sealers using two different obturation techniques. Materials and methods: Forty freshly extracted single-rooted mandibular premolars were selected, decoronated, and mechanically prepared using EdgeFile X7 rotary files to size 40/0.04. Samples were randomly divided into 4 groups (n=10). In Group I: samples were obturated with AH Plus resin sealer using cold lateral compaction technique, Group II: samples were obturated with AH Plus resin sealer using single cone technique, Group III: samples were obturated with NeoSealer Flo bioceramic sealer using cold lateral compaction technique and Group IV: samples were obturated with NeoSealer Flo sealer with single cone technique. Fracture resistance testing was done using a universal testing machine. The data were analysed statistically using one-way analysis of variance followed by pair-wise comparison using Tukey’s post hoc test. Results: Neosealer Flo samples had significantly higher fracture resistance than AH Plus samples (p<0.001). Regardless of type of sealer used, single cone obturation technique had significantly higher fracture value than lateral compaction (p<0.001). Conclusion: Obturation using NeoSealer Flo sealer with single cone technique improved the fracture resistance of endodontically treated teeth.
Dietary Fiber Consumption and Colorectal Cancer: A Case-Control Study

Background: Colorectal cancer (CRC) is an increasingly imperative cause of morbidity and mortality. This study aimed to determine the association between dietary fiber consumption and CRC. Methods: This age- and sex-matched case-control study was conducted from July 2020 to June 2021 at the Combined Military Hospital (CMH) and the National Institute of Cancer Research and Hospital (NICRH) in Dhaka. A total of 102 cases and 102 controls were selected through purposive sampling. Cases were adult patients diagnosed with CRC, while controls were individuals without cancer. Data were collected using a pretested semistructured questionnaire and checklist, which included information on socio-demographic characteristics, colorectal cancer attributes, and dietary fiber consumption. Face-to-face interviews were conducted to collect data from both cases and controls. Results: The mean (±SD) age of the cases and controls were 44.7±13.9 years and 45.6±13.3 years, respectively, with a male-female ratio of 1:1.3 in both groups. A significantly higher proportion of cases (53.9%) lived in joint families compared to controls (39.2%) (p=0.035). Type 2 diabetes mellitus (T2DM) was significantly more prevalent in cases (27.5%) than in controls (15.7%) (p=0.041) among the comorbid conditions. Majority of the cases (72.5%) consumed low dietary fiber (<25 grams/day), while three-fifths of the controls (67.6%) consumed normal to high dietary fiber daily (p<0.001). After adjusting for the type of family, residence, and presence of T2DM, participants who consumed low dietary fiber were found to be 7 times more likely to develop CRC than those who consumed normal or high dietary fiber (OR=7.003, 95% CI = 3.616-13.565, p<0.001) based on binary logistic regression. Conclusion: The findings of this study suggest that low dietary fiber consumption is associated with an increased risk of CRC. Specific measures that could be taken to promote a high-fiber diet include increasing awareness through public health campaigns, providing nutrition education, and ensuring that healthy food options are readily available and accessible to people from all socioeconomic backgrounds.

Results of treatment of 20 Iraqi Patients with Newly Diagnosed High and Intermediate grade Non-Hodgkin's Lymphoma with VACOP-B

Background: CHOP regimen was the standard treatment for patients with diffuse large and mixed cells Non-Hodgkin's lymphoma (NHL) even in comparison with second and third generation regimen. Recently Rituximab –CHOP is considered the standard treatment for aggressive B-cell NHL while CHOP (alone) is so for aggressive T-cell NHL, yet more than one study investigates another regimen which is VACOP-B and some showed its superiority over CHOP. Prior to the introduction of Rituximab, we used VACOP-B in the treatment of high &intermediate grade NHL in adult Iraqi patients as an alternative to CHOP. Patients and Methods:We performed a prospective analysis of 20 adult patients who, between April 2000 and October2005, received VACOP-B chemotherapy for high and intermediate grade NHL. The weekly regimen consisted of: doxorubicin50 mg/m2 i.v. weeks 1,3,5,7,9,11; cyclophosphamide350 mg/m2 i.v. weeks 1, 5, 9; etoposide 100mg/m2iv, weeks 3,7,11; vincristine1.4 mg/m2 i.v. (2 mg max.) weeks 2, 4, 6, 8, 10;bleomycin 10 mg/m2 i.v. (max. 15 mg) weeks 2,4, 6,8, 10; methotrexate12.5 mg intratheical was given in selected patients. ; prednisolone 60mg p.o. daily for 2 weeks, reduced to 60 mg every other day for 10weeks.The patients treated were aged 25-50 years, 8(40%) had high grade (Working Formulation )NHL; 12 (60%) had intermediate grade NHL;seventeen patients(85%) had Stage III/IV disease; and 3 (15%) had stage II,bone marrow involvement seen in 3(15%)patients . patients distribution regarding age adjusted international prognostic index(aaIPI)was 8(40%)with aaIPI 0,1and 12(60%)with 2,3. Follow-up time from completion of VACOP-B chemotherapy ranged from 6 months to 40 months (median 22). Results: VACOP-B induced a complete response (CR) and partial response (PR) in 70% and 15% respectively, whilst one patient had no response to treatment and died due to progression of the disease, 2 patients died due to treatment related toxicity. The three year disease free survival (DFS) was 78%, where 4 patients relapsed, one of them in the central nervous system. This study showed 3-year overall survival (OS) 100% for those with a IPI 0-1and 48% for those with aa IPI 2-3. Tolerance to treatment was measured by WHO toxicity scores. The hemoglobin (Hb) toxicity median score for all patients was grade 1 (Hb 9.5-10.9 g/dl), and the white cell count (WCC), toxicity score was grade 2(WCC 2.0-2.9 x 109/1). No platelet toxicity was observed. Ten per cent of patients suffered grade 3 severity infections requiring antibiotics and there was two treatment related death. Conclusions: VACOP-B chemotherapy is an effective regimen for high and intermediate grade NHL, with an encouraging result in patients with aaIPI 0, 1. although chemotherapy was given weekly, the tolerance to treatment was acceptable. Studies comparing VACOP-B vs. CHOP chemotherapy to decide the exact role of the first in treating high grade &intermediate grade NHL, in the absence of Rituximab, are still needed.

Does home and community-based services use reduce hospital utilization and hospital expenditure among disabled elders? Evidence from China

Introduction In the background of aging in place, home and community-based services (HCBS) have been playing an increasingly important role in long-term care (LTC) security systems. However, it is still uncertain whether and how HCBS use affects hospital utilization and the corresponding expenditures. Methods Using data from the China Health and Retirement Longitudinal Survey (CHARLS) and the China City Statistical Yearbook, the instrumental variable (IV) approach is applied to identify the causal effects of HCBS use on hospital utilization and hospital expenditure among disabled elders. Results We find that HCBS use significantly reduces the probability of being hospitalized, the times of hospitalization, and the length of inpatient stay, as well as the total, out-of-pocket and reimbursement inpatient expenditures, demonstrating not only the substitution impact of HCBS for hospital care but also the effectiveness of medical expenditure control in LTC security systems. Heterogeneity analysis shows that the impacts of HCBS use on hospital utilization and hospital expenditure concentrate on disabled elders who are younger, male, living in urban areas, or from higher-income households; both healthcare and spiritual consolation services have significant negative effects, while the anticipated effects of daily care service use are not supported. The possible mechanisms are the substitution of HCBS for hospital care and the improvements in both the physical and psychological health of disabled elders. However, the mechanism of adverse events decrease is not verified, which needs to be investigated further with more proxy variables. Conclusion This study provides empirical evidence that HCBS use can not only reduce hospital utilization and hospital expenditure among disabled elders but also improve their physical and psychological health. Policy designs should emphasize the orientation of HCBS, ensure the fundamental and central position of HCBS in the formal care service system, pay more attention to the accessibility and affordability of HCBS for fragile groups, and diversify and optimize the development of the health service and the spiritual consolation service.
Unravelling Teacher Turnover: Exploring Factors at the Province, School District and School Levels

This study aimed to determine how teachers ranked the reasons for turnover at the province, school district, and school levels based on their importance. For this purpose, the most important reasons for turnover at the province, school district and school levels were determined based on teachers' judgments. At the same time, it was determined how teachers' opinions differed in terms of gender, marital status, tenure status and years of seniority. The results showed the psychological dimension of the problems faced by teachers and provided an opportunity for a comprehensive analysis of the teachers' acceptance area. Within this scope, a general survey model was conducted during the 2022-2023 academic year with 722 teachers working in official institutions in the Şehitkamil and Şahinbey districts of Gaziantep Province. To identify reasons for teacher turnover, a literature review was conducted, interviews were conducted with teachers, and expert opinions were obtained. The identified turnover reasons were classified at the province, school district, and school levels, and a “Teacher Turnover Reasons Ranking Form” was created after the pilot study. Teachers were asked to rank the reasons for turnover according to their priorities and judgments. Based on the teachers' perspectives, at the city level, Future Plans and Distance from Family; at the school district level, people’s Approaches to Education, People's Negative Attitudes and Behaviours; and at the school level, Student Behaviour Problems and High Student Numbers were identified as the most important reasons for teacher turnover. According to the research findings, teachers prioritized their individual and family needs at the city level, the attitudes and behaviours of stakeholders at the school district level, and problems stemming from students at the school level as significant reasons for turnover. The research findings reveal that teachers perceive their individual and familial needs at the provincial level, the attitudes and behaviours of stakeholders at the school district level, and student-related issues at the school level as significant factors contributing to turnover.
SOIL WATER CONTENT AND WATER STORAGE MONITORING USING ELECTROMAGNETIC INDUCTION

Water content is a critical parameter for evaluating spatial and temporal variability in subsurface water movement. Water storage is also important for monitoring the soil water balance and for validation of water balance models. The purpose of this study was to evaluate the use of electromagnetic induction to predict average water content or storage and changes in water content in the upper 1.50 m of the soil profile at point locations and over an area. The technique was applied to a field-scale prototype engineered cover (17 m × 34 m) designed for waste containment. Water content was monitored with a neutron probe, and bulk soil electrical conductivity was monitored with a Geonics EM38 ground conductivity meter at 10 locations at approximately monthly intervals over a 3-yr period. A simple linear regression model was developed to predict average water content in the upper 1.50 m of the soil profile at any location at any time (R 0.80, average standard deviation = 0.009 m/m) and spatially averaged water content over the entire area at any time (R 0.99, average standard deviation = 0.003 m/m). The model residual water content values did not appear to drift significantly with time, indicating that once the model is calibrated over a sufficient range of water content values with the neutron probe, further neutron probe measurements may not be necessary. EM induction has several advantages over traditional techniques for monitoring water content, including nonradioactivity, speed and ease of use over large areas, and noninvasive character, which is important for avoiding development of preferred pathways.
Comparative Assessment of the Periodontal Findings in Child Subjects With a Normal Body Mass Index and in Obese Subjects

Background: Obesity in children is a concerning issue affecting a large population globally. Obesity and overweight are risk factors for various medical conditions, including periodontal diseases, hypertension, cerebrovascular disease, cardiovascular disease, and/or diabetes. Aim: The study aimed to comparatively assess the periodontal findings in child subjects with a normal BMI and in obese subjects. Methods: The present observational study aimed to comparatively assess 216 school-going child subjects that were divided into two groups: non-obese (BMI<25) and obese, with BMI≥25 having equal gender distribution. In both groups, clinical attachment loss (CAL), probing depth (PD), and bleeding on probing (BOP) were assessed along with a questionnaire on oral hygiene and dietary habits. The data gathered were statistically analysed. Results: The study results showed that in obese subjects, significantly higher values were seen for probing depth, bleeding on probing, and plaque index compared to non-obese subjects with p<0.05. However, no significant difference was noted in the CAL of obese and non-obese subjects (p>0.05). Conclusion: The periodontal status is compromised in obese subjects with higher values of probing depth, bleeding on probing, and plaque index compared to child subjects with normal weight. The level of CAL does not differ significantly between obese and non-obese child subjects.
Long-term administrations of microplastics induces hepatorenal and intestinal tissues damages in experimental mice

Microparticles (MPs) are well recognized as a global concern arising from plastic waste. MPs can cause various environmental and health problems. This study was conducted to evaluate the effect of the administrations with MPs for short and long terms on the pathophysiological and histological status of hepatorenal and intestinal tissues in mice. Forty (40) male CD-1 mice were divided into 4 groups (n = 10) as follows; the first group (Gp1) was served as a negative control, administered orally with 200 µl of dist. H 2 O. Gp2 was administrated orally daily with MPs (66.4 mg/kg b. wt) for 28 days. Gp3 was administered as in Gp1 for 120 days and used as a negative control for Gp4. Gp4 was administrated with MPs as in Gp2 orally for 120 days. All groups were sacrificed, and blood samples, liver, kidney, and intestinal tissue samples were collected for haematological, biochemical, and histopathological analysis. The results showed that the short-term administration of MPs did not show significant changes on the haematological, biochemical parameters, histological investigations of the hepatorenal and intestinal tissues, however, administration for long term led to significant changes pathophysiological and histopathological alterations in the liver, kidney, and intestinal tissues. In conclusion, administration of MPs for long term could be harmful on the vital organs
Widespread Occurrences of Högbomite-2N2S in UHT Metapelites from the Betroka Belt, Southern Madagascar: Implications on Melt or Fluid Activity during Regional Metamorphism

Ho« gbomite occurs in spinel^garnet^cordierite^sillimanite-bearing metapelites over an area of 60 km 12 km in the northern parts of the Betroka belt, southern Madagascar. X-ray diffraction analyses indicate that the ho« gbomites belong to the 2N2S polysome type ‘P63cm’with a1⁄4 5·718^5·723 — and c1⁄418·30^18·42 —. The chemical composition of ho« gbomite varies over a relatively wide range (in wt %):TiO21⁄4 3·82^6·09, Al2O31⁄4 59·45^63·04, Cr2O3 0·63, FeO1⁄4 20·14^30·7, MgO1⁄4 2·19^5·76, MnO 1·35, ZnO 8·78, and CaO 0·27.The ho« gbomites form solid solutions involving the substitutions (MgþFe2þþMnþCa)1⁄4Zn, 2(AlþCrþFe3þ)1⁄4Tiþ (MgþFe2þþMnþCaþZn), and (AlþCr)1⁄4Fe3þ. The ho« gbomite was formed in polyphase domains hosted by discrete magnetite, ilmenite, and/or hematite in close association with spinel, corundum, and/or rutile. Petrographic characteristics and the compositions of ho« gbomite suggest that this mineral was formed by various retrogressive reactions in different microdomains. Ho« gbomite forms at the expense of corundum spinel ilmenite Ti-hematite rutileþH2O and exhibits systematic compositional relationships with the neighboring spinel in Fe2þ^Mg, Fe3þ^Al and Fe2þ^Zn, suggesting attainment of equilibrium between these two minerals. The ho« gbomite-bearing rocks underwent ultrahigh-temperature (UHT) crustal metamorphism following a clockwise P^T trajectory. The textural features suggest the dehydration melting reaction biotiteþ sillimaniteþ quartz1⁄4 cordieriteþgarnetþmelt. The peak mineral assemblage garnetþ cordieriteþ spinelþ sillimaniteþ quartz was stabilized at 880^10608C and 4·5^6·6 kbar. Decompression cooling is evident from a reaction forming cordierite at the expense of spinel and quartz and a cordierite^spinel corona formed between garnet and sillimanite by the reaction garnetþ sillimanite1⁄4 cordieriteþ spinel. Ho« gbomite crystallization took place after the peak metamorphic event, probably accompanied by anatectic hydrous melts formed during metamorphism or introduction of hydrous fluids along shear zones over a wide area. We propose that ho« gbomite can evidently grow even at high metamorphic grade (T 8008C and P 4 kbar) if a source of water is present, and is an indicator of significant hydrous melt or fluid activity during the early retrogressive stage of regional metamorphism.
Design of an Ultra-Wideband Antenna Feed and Reflector for use in Hydrogen Intensity Mapping Interferometers

This paper describes the design of a 5.5:1 bandwidth feed antenna and reflector system, intended for use in hydrogen intensity mapping experiments. The system is optimized to reduce systematic effects that can arise in these experiments from scattering within the feed/reflector and cross-coupling between antennas. The proposed feed is an ultra wideband Vivaldi style design and was optimized to have a smooth frequency response, high gain, and minimal shadowing of the reflector dish. This feed can optionally include absorptive elements which reduce systematics but degrade sensitivity. The proposed reflector is a deep parabolic dish with $f/d = 0.216$ along with an elliptical collar to provide additional shielding. The procedure for optimizing these design choices is described.
