Competition Between Cyclization and Unusual Norrish Type I and Type II Nitro-Acyl Migration Pathways in the Photouncaging of 1-Acyl-7-nitroindoline Revealed by Computations
Authors: Morgante Pierpaolo , Guruge Charitha , Ouedraogo Yannick P. , Nesnas Nasri , Peverati Roberto
Published: September 2020

The 7-nitroindolinyl family of caging chromophores has received much attention in the past two decades. However, its uncaging mechanism is still not clearly understood. In this study, we performed state-of-the-art density functional theory calculations to unravel the photo-uncaging mechanism in its entirety, and we compared the probabilities of all plausible pathways. We found competition between a classical cyclization and acyl migration pathways, and here we explain the electronic and steric reasons behind such competition. The migration mechanism possesses the characteristics of a combined Norrish Type I and a 1,6-nitro-acyl variation of a Norrish Type II mechanism, which is reported here for the first time. We also introduced a computational procedure that allows the estimation of intersystem crossing rate constants useful to compare the relative quantum yield of substituted cages. This procedure may pave the way for improved cage designs that possess higher quantum yields and a more efficient agonist release.

Compositional search within multinary perovskites employing brute force synthesis are prohibitively expensive in large chemical spaces. To identify the most stable multi-cation lead iodide perovskites containing Cs, formamidinium (FA) and methylammonium (MA), we fuse results from density functional theory (DFT) calculations and in situ thin-film degradation test within an end-to-end machine learning (ML) algorithm to inform the compositional optimization of CsxMAyFA1-x-yPbI3. We integrate phase thermodynamics modelling as a probabilistic constraint in a Bayesian optimization (BO) loop, which effectively guides the experimental search while considering both structural and environmental stability. After three optimization rounds and only sampling 1.8% of the compositional space, we identify thin-film compositions centred at Cs0.17MA0.03FA0.80PbI3 that achieve a 3x delay in macroscopic degradation onset under elevated temperature, humidity, and light compared with the more complex state-of-the-art Cs0.05(MA0.17FA0.83)0.95Pb(I0.83Br0.17)3. We find up to 8% of MA can be incorporated into the perovskite structure before stability is significantly compromised. Cs is beneficial at low concentrations, however, beyond 17% is found to contribute to reduced stability. Synchrotron-based grazing-incidence wide-angle X-ray scattering (GIWAXS) further validates that the interplay of chemical decomposition and phase separation governs the non-linear instability landscape of this compositional space. We reveal the detrimental role of the ẟ-CsPbI3 minority phase in accelerating degradation and it can be kinetically suppressed by co-optimising Cs and MA content, providing insights into simplifying perovskite compositions for further environmental stability enhancement. Our approach realizes the effectiveness of ML-enabled data fusion in achieving a holistic, efficient, and physics-informed experimentation for multinary systems, potentially generalisable to materials search in the vast structural and alloyed spaces beyond halide perovskites.

Published: September 2020

Managing the demand, prevalence, and the design of partial tooth loss is imperative to recognize the prosthetic necessities of the patients. A factor that may affect prosthodontic work is the patients' awareness of the most advanced technologies in aesthetic dentistry. The choice of prosthetic replacement is largely defined by the patient's choice and budgetary status, accessible technology and expertise, as well as the number of missing teeth. The aim of this study was to identify the preference of treatment choice from implant and FPD for the patients treated at a private dental hospital. The sample size consisted of 1122 patients who had FPDs or implants. The case sheets of patients were obtained from the patient record system. The data of each patient was obtained and tabulated. In our study, 54.46 % of patients were male, 45.45 % of patients were female, and 0.09 % belonged to the transgender population. 3.21 % patients belong to the age group of less than 20 years, 54.06 % patients in the age group 21-40 years, 35.5 % patients in the age group 41-60 years and 7.2 % patients in the age group above 60 years. The overall FPD were 809 across all age groups with the maximum in the age group 21-40 years (40.59%). Overall implants were 312 across all age groups with the maximum at 21-40 years (13.47%). It was concluded that there is a significant difference in the preference of patients opting for implant vs FPD, in which FPD was highly opted by the patients. Although removable partial dentures extended to play a significant role in prosthetic teeth replacement, the use of FPDs and dental implants showed an increase in number.

Published: September 2020

This study aimed to reiterate the use of Chemistry demonstrations as effective teaching tools to students while addressing some of its drawbacks, which discourages teachers from doing them such as cost and safety. Four chosen existing Chemistry demonstrations (Blue Bottle Experiment, Copper Sulfate Experiment, Blown Away, Dancing Flames) were modified by using substitute reagents, which are more accessible, relatively safer, and at lower cost. These demonstrations were chosen based on how easily the substitute reagents will be obtained. Afterwards, with the permission of a private junior high school, they were presented to a group of Grade 9 students of their choosing. The students were asked to evaluate each demonstration using a Likert scale-based questionnaire. This questionnaire rates each demonstration in terms of aesthetics, the materials and procedure done, effectiveness to explain certain Chemistry topics, safety, and the students’ overall judgment regarding the use of demonstrations as teaching tools. By converting their evaluation to quantitative values, the demonstrations scored high in all major categories. With this, it is highly recommended to explore other Chemistry demonstrations for possible modifications, which can be integrated in lecture classes.

Women's Sexual Satisfaction and Overall Well-being: Examining Relationship Satisfaction, Sexual Agency, Sociosexual Orientation and Relationship Status
Authors: Curley Christine
Published: September 2020

Medical and psychological research has found a strong association between sexual satisfaction and overall well-being. However, few studies have addressed whether the relationship between women’s sexual satisfaction and overall well-being differs for women of different ages. This mixed-method study recruited 347 women aged 18 to 76 and found (1) a positive significant association between age, relationship satisfaction, and sexual satisfaction and overall well-being, and higher levels of sexual satisfaction are associated with higher levels of overall well-being. However, age was unrelated to sexual satisfaction and overall well-being, and; (2) while relationship satisfaction interacted with sexual satisfaction and overall well-being, there was no interaction effect of age. Results also indicated that relationship status was unrelated to women's sexual satisfaction. However, sexual satisfaction was positively associated with overall well-being. Semistructured interviews of eight women (ages 20-52) explored women’s attitudes and behaviors pertaining to sex, sexual satisfaction, and wellness. Findings from this study can inform future health psychology and health education efforts to promote the pursuit of sexual satisfaction as a set of healthy behaviors fundamental to overall well-being for women of all ages.
Why Can't We Sleep? Impact of Race and Social Status on Sleep in College
Authors: Silva-Jones Jillian
Published: September 2020

This study assessed the impacts of discrimination, microaggressions, and socioeconomic status (SES) on sleep in college students. The study also assessed moderators of racial identity and sleep hygiene as potential buffers of the impact from discrimination. Method: The impacts of lifetime discrimination and microaggressions over the past six months on sleep over the past month was assessed using an online survey (Study 1), and daily impacts of microaggressions on sleep was assessed from a daily diary study (Study 2). Results: The results showed modest correlations for the impact of discrimination, microaggressions, and SES on sleep, with the overall patterns suggesting a detrimental impact on sleep for students of color. The moderators of racial identity and sleep hygiene did not indicate significant effects. Conclusion: The impact of discrimination and microaggressions on sleep for students of color is promoting poorer sleep outcomes in comparison to White students. Additionally, higher SES contributed to better sleep outcomes; however, for students of color, higher SES was not shown to buffer the impact of discrimination on sleep outcomes.

Authors: Doremus Wendy
Published: September 2020

Healthcare systems are increasingly accountable for safety and quality. States have a key role in protecting and promoting the health of their youth, setting regulations and standards for school health services structures and processes.
Yet, the lack of an instrument for state-level self-assessment of equity and quality infrastructure supports hinders progress toward improving in school health services delivery. This macro health system project, conducted in three phases,
developed a valid and reliable instrument for state-level self-assessment of infrastructure necessary for supporting quality school nursing services. The phases were identification of state-level structures and processes domains and indicators;
a content expert survey evaluating the validity of the measure; and a pilot test of the measure with Rhode Island state-level school health leaders. The resulting State-level School Health Infrastructure Measure, comprised of seven domains and related
indicators assesses for the presence of evidence-based school nursing practice standards and resources; school nursing workforce professional competency standards and professional development; school nursing delivery of school-age population healthcare;
equity in student access to professional school nursing services; cross-sector state leadership, governance, collaboration, linkages, and networks among health and youth service entities; school health information technology and data integration; and stable
funding for school nursing services. The instrument appears to be feasible, cost effective, valid, and reliable for assisting states to identify and build quality school nursing services delivery capacity to improve the health of school-age youth.

Published: September 2020

This study investigates the effects of changing in the properties of face and core wythes in structural sandwich panels (with dimensions of 500 500 mm and 120 mm total height). Concrete face wythes of three grades (80, 70, 37) MPa, thicknesses of (25, 35, and 45) mm, and three types of core materials (high density foam, polyethylene foam, and palm bark) were used in the production of panels. Steel shear connectors were installed in the panels with angle of 45º. Three-point bending load test was carried out on all panels and results were compared with both of the theoretical extremes capacities of non- composite and fully-composite states and ANSYS software results. The degree of composite action (%) and the (strength/weight) ratio were the main parameters that judged the specimens. It was found that upgrading concrete increased overall strength of slabs especially in high strength concrete (80 MPa), however the use of lightweight concrete (70 MPa) caused high (strength/weight) ratio due to very lightweight. Results revealed that decreasing thickness of concrete face wythes had a positive effect on strength/weight ratio (although the ultimate loads decreased) that enhanced the performance of panels as lightweight structural panels. The optimum face wythe thickness is that of 2.5 cm and has high (strength/weight) ratio. It was noticed that adding polyethylene foam as a core material results in positive effect and high (strength/weight) ratio. Results revealed that high strength concrete (80 MPa) and light-weight concrete (37 MPa) are very successful in the production face wythes of precast light-weight sandwich panels that can obtain high (strength/weight) ratio and high percent of composite action.

Particle Swarm Optimization algorithm (PSO) has been hybridized with the Fish School Search (FSS) algorithm to improve the capability of the algorithm. FSS presents an operator, called as collective volition operator, which is capable to auto-regulate the exploration-exploitation trade-off during the algorithm execution. Since the PSO algorithm converges faster than FSS but cannot auto-adapt the granularity of the search, we believe the FSS volition operator can be applied to the PSO in order to mitigate this PSO weakness and improve the performance of the PSO for dynamic optimization problems. In order to evaluate the efficiency of the proposed Volition Particle Swarm Optimization (VP) algorithm, it has been tested in standard IEEE 30 bus test system and compared to other reported standard algorithms.  Simulation results show that Volition Particle Swarm Optimization (VP) algorithm is more efficient then other algorithms in reducing the real power losses with control variables are within the limits.
YADI NAASTI DAIVAM- A PRINCIPLE OF PREVIOUS LIFE’S DEEDS

Published: September 2020

It is commonly observed all throughout history, felt all throughout our lives, that often, the achievements gained by people are not really tantamount to the amount of effort they have put in to try to achieve the same. This raises doubts on the saying ‘Hard work is the key to success’ as some people don’t work hard at all but achieve greater than those who have bet their lives on the same goal. To these conflicts that arise in our minds, causing depression and anxiety symptoms in some people can all be answered by a quarter of a verse found in the ancient text of Ayurveda, Charak Samhita. It also provides reasoning and solutions about the daily conflicts in society to some extent. Six principles were extracted from the same quarter of the verse by the author. It was concluded that people should: remain in present time and perform duties with utmost of precaution, not get discouraged by failures as they do not always imply that their present actions are incorrect, keep in mind that what they get is due to the balance of duties that they have performed, remember that whether the duties were performed in present or past, no one else is responsible for anyone else’s agony or pleasure.
HUMAN TISSUE BIOMAGNETISM ATTRACTING IRON PARTICLES AS PROPOSED MECHANISM ELUCIDATING THE IRON AND ATHEROSCLEROSIS HYPOTHESIS

Published: September 2020

The purpose of this manuscript is to introduce a mechanism that could be applied to the “Iron Atherosclerosis Hypothesis”. Published data from eleven countries clearly indicate that the mortality from cardiovascular diseases is correlated with liver iron, thus the hypothesis. The bridging field of biomagnetism is herein presented as a tool for the scientific explanation for this illness. Atherosclerosis is a disease directly linked to high mortality and morbidity due to a several risks factors; and in spite of several behavioral modifications and drug therapy the prevalence of the disease continues. Amongst one of the factors influencing the disease progression is high iron levels in blood. Studies show post-menopausal women having a greater incidence of vascular disease that were correlated with higher levels of stored iron in this population. It has been stated that like any other theory in cardiovascular medicine, the iron-atherosclerosis hypothesis will undergo many trials and tribulations before it is proven or refuted. This manuscript re-introduces documentation of an intrinsic property of in vivo human tissue, which is attracting very fine iron particles. It must be noted that iron is a paramagnetic material, therefore attracted to a magnetic field.
DELINEATION OF GEOMETRY AND SPATIAL DISTRIBUTION OF BASIC BODIES USING MAGNETIC AND RESISTIVITY METHODS IN SOHAGPUR COAL FIELD AREA, MADHYA PRADESH

The state of Madhya Pradesh in Central India is known to bear ‘A’ grade coal seams within Gondwana basin. An alluvium-covered area to the north-east of Shahdol was considered to be prospective for the exploration of coal. A number of basic intrusive are encountered in the area and these appear to have played an important role for enhancement of the rank of coal seams. Delineation of the geometry and spatial distribution of these basic bodies has therefore become necessary for exploration of high rank coal seams. Magnetic and resistivity surveys were mainly carried out. Geologically, the alluvium covered area was known to be composed of rocks of different ages such as Precambrian, Gondwana Triassic, Cretaceous (trap) and older alluvium in succession. Gondwana basins are formed over basement depressions or in the downthrown side of the faulted Precambrian. Gondwana sediments lying over such basement sub-basins are prospective areas for the exploration of coal. The magnetic map was vitiated through the presence of high amplitude and small wavelength anomalies due to a thick blanket of basic bodies lying above the Gondwana sediments. Fluctuations in magnetic responses are observed at a few locations which may be due to the presence of basement faults? Low intensity but distinct anomaly patterns are observed in the south-western part of the area possibly indicating subsurface basic intrusive. 2D modeling of the magnetic data has effectively brought out the basement depth varying between 680 m to 1460 m an increasing trend from west to east. Selected resistivity soundings confirm that the overlying high resistivity layer (107-390 Ohm-m) and of thickness (0.7-386.3 m) may possibly indicate the geometry of basic bodies from the surface to depth of 547.5 m. The basement could not be picked up.

Currently, the food industry pays great attention to the research of antioxidants used as food additives and functional food ingredients. Monitoring the antioxidant activity (AOA) of foods containing dietary antioxidants serves as an innovative tool for the food industry development and is an urgent research task. The article presents data on the development, research and application of a single-use potentiometric sensor system based on modified thick-film electrodes made by screen printing to determine the beverages AOA. In the sensor system, the thick-film carbon-containing electrode (TCE) is modified with gold nanoparticles (AuNP), and the thick-film silver-containing electrode (TSE) is modified with a precipitate of silver chloride and ferricyanide (O) and covered with a protective Nafion layer (N). The researchers analyzed the electrochemical and operational characteristics of AuNP/TCE and N/O/TSE. A man found that carbohydrates (glucose, fructose and sucrose) did not affect, and ethyl alcohol affected the potential change in the electrochemical cell and, thus, the amount of antioxidant activity of the drink. The authors provide methodological approach for results correcting of determining the antioxidant activity of alcoholic beverages. The results of AOA beverages determining obtained using commercial electrodes and the developed sensor system are in good agreement (according to the criteria of Fischer and Student).

Objectives: To evaluate the diagnostic accuracy of frozen section in detecting malignant gliomas, taking histopathology as gold standard. Study Design: Cross-Sectional study. Setting: Neurosurgery Department, Aga Khan University Hospital, Karachi. Period: From March 2018 to Jan 2019. Material & Methods: Through consecutive sampling technique, total 100 specimens from patients suspected of malignant gliomas on MRI brain with contrast, who were admitted in the neurosurgery department for elective tumor surgery were included. Intraoperatively, the specimen from the lesion identified on imaging through neuro-navigation was taken and sent to histopathology department for frozen section analysis. The histopathology consultant was pre-informed about the case and probable time of receiving the specimen. The specimen for frozen section was sent in a dried container without formalin. Once received in pathology department, the tissue is rapidly cooled through a cryostat which converts tissue water into the ice and makes the tissue rigid for cutting into slices and viewing under the microscope for identifying the neoplastic tissue. The consultant histopathologist was request to provide frozen section report immediately and to keep the remaining specimen for definitive histopathology reporting as well. Data of malignancy on both Frozen Section and formal histopathology report was noted and comparison was done. Results: Mean age of the patients was 36.7±8.76 years. There were 64 (64%) male patients and 36 (36%) female patients. Diagnostic accuracy of frozen section taking histopathology as a gold standard shows that sensitivity was found to be 83.3%, specificity 84.4%, Positive predictive value (PPV) 71.4% and negative predictive value (NPV) 91.5% & Overall diagnosis accuracy was found 96.6%. Conclusion: The Diagnostic accuracy of frozen section (FS) in detection of brain malignant gliomas was found to be satisfactory. It has a diagnostic accuracy of 96.9%, sensitivity 83.3%, specificity 84.4%, Positive predictive value (PPV) 71.4% and negative predictive value (NPV) 91.5%.
