Abstract
Previous studies have suggested that arsenic crosses the placenta and affects the fetus development. The study under consideration aims to show comparative ameliorative effect of Moringa oleifera leaf and flower extracts against sodium arsenate induced fetus toxicity of mice. Pregnant mice (N=44) were kept in lab and divided into eleven group from (A to K) and were orally administered the doses 6 mg/kg, 12 mg/kg for sodium arsenate, 150 mg/kg and 300 mg/kg for Moringa oleifera leaf extracts (MOLE) and 150 mg/kg and 300 mg/kg for Moringa oleifera flower extracts (MOFE) comparing with control. The investigation revealed evident reduction in the fetuses weight, hind limb, fore limb, tail and snout length, crown rump and head circumferences well as malformations in tail, feet, arms, legs, skin and eyes in the negative control group (only administered with sodium arsenate). Co-administration of sodium arsenate with MOLE and MOFE ameliorate the reversed effect of sodium arsenate on the shape, length, body weight and DNA damage of fetus significantly at 95% confidence interval. However, Moringa oleifera leaf extract showed more significant results in comparison to Moringa oleifera flower extract. Hence concluded that Moringa oleifera leaf extract ameliorated the embryo toxic effects of sodium arsenate and can be used against environmental teratogens.

Abstract
One-atom-thick rare-earth/noble metal (RE-NM) compounds are attractive materials to investigate two-dimensional magnetism, since they are easy to synthesize into a common RE-NM2 structure with high crystal perfection. Here we perform a comparative study of the GdAu2, HoAu2, and YbAu2 monolayer compounds grown on Au(111). We find the same atomic lattice quality and moiré superlattice periodicity in the three cases, but different electronic properties and magnetism. The YbAu2 monolayer reveals the characteristic electronic signatures of a mixed-valence configuration in the Yb atom. In contrast, GdAu2 and HoAu2 show the trivalent character of the rare-earth and ferromagnetic transitions below 22 K. Yet, the GdAu2 monolayer has an in-plane magnetic easy-axis, versus the out-of-plane one in HoAu2. The electronic bands of the two trivalent compounds are very similar, while the divalent YbAu2 monolayer exhibits different band features. In the latter, a strong 4f-5d hybridization is manifested in neatly resolved avoided crossings near the Fermi level. First principles theory points to a residual presence of empty 4f states, explaining the fluctuating valence of Yb in the YbAu2 monolayer.

Abstract
Cohort selection The aim was to evaluate interventions to minimise microbial contamination from aerosol generating procedures in the dental office. Seven electronic databases were searched using key words such as 'aerosols', 'droplets', 'spatter', 'microbial loads' etc to identify relevant randomised controlled trials and prospective non-randomised clinical trials until 6 April 2020.Data sources PubMed; Scopus; Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; Open Grey; ClinicalTrials.gov; National Research Register; and hand searches.Data analysis Eligible studies were analysed for effectiveness of various interventions on the microbial counts in the aerosols generated in the dental office using predefined criteria. Data were analysed for assessment of quality of evidence and confidence in the estimated effect, risk of bias and other analyses using Stata 15.1 software. PRISMA guidelines extension for network meta-analysis were followed for reporting.Results Initial search identified 266 studies, of which 35 were evaluated for full text. Finally, 29 studies fulfilled the eligibility criteria for qualitative synthesis. The majority of the included studies were published in the last decade, and 21 out of the 29 studies were randomised controlled trials. However, based on comparable procedural settings (study design, study populations, interventions and outcome measures), only 11 were eligible for contribution to the network meta-analysis. The setting of all interventions was ultrasonic scaling of adult patients in a clinical dental practice environment, and involved 16 direct and 29 indirect comparisons. A multivariate meta-analysis showed pre-procedural mouth rinse with tempered chlorhexidine 0.2% at 47°C was most effective in reducing post-procedural bacterial load compared to the control. A mean difference of -0.92 (95% CI -15.4 to -0.29) in log10 colony-forming units was observed in air samples within 90 cm of the dental unit.Conclusions Notwithstanding the limitations of this network meta-analysis, pre-procedural mouth rinse with tempered chlorhexidine appears to be most effective in reducing bacterial counts in aerosols generated during dental operative procedures. Further randomised controlled clinical trials based on robust designs are required to establish the effectiveness of antimicrobial agents in reducing aerosol-related microbial loads (bacteria and viruses) in clinical environments.

Abstract
Aims To evaluate the self-perceived preparedness of final year dental undergraduate students in the United Kingdom.Methods Dental undergraduate students in their final year were invited by email through the Dental Schools Council (DSC) to provide their responses to an online preparedness assessment scale. The data analysis was carried out using the RUMM2030 software which is specifically designed for Rasch analysis, a measurement model based on item response theory.Results Students felt adequately prepared to carry out simple clinical procedures and communication skills. However, low scores were reported on ability to assess orthodontic treatment needs, treatment planning, crowns, endodontics, research skills, referral for suspected oral cancer and raising concerns regarding inappropriate behaviour of colleagues.Conclusions The scale used in this study explored the self-perceived preparedness on a range of cognitive, clinical and behavioural attributes. The data show that the students felt prepared for the majority of the attributes expected from dentists. However, a number of areas were identified where students may benefit from further training and consolidation.

Abstract
Polymorphic transformations in LaPO4 are investigated as a function of pressure using density functional theory (DFT) based calculations under the generalized gradient approximation. The monazite-type (P21/n) → barite-type (Pbnm) structural transformation is identified at 16.2 GPa and experimentally, no transformation is observed near this pressure. A discontinuity in the pressure-volume relation (of 4.16% volume discontinuity compared to the monazite structure at the same pressure) and unit-cell dimensions is observed around 28 GPa, which matches well with the previous experimental results. The pressure of discontinuity matches the DFT calculated monazite-type (P21/n) → post barite-type (P212121) structural transformation pressure. The equation of state, single crystal elastic constants and phonon dispersion curves of the different polymorphs as a function of pressure are determined. Both the barite-type (Pbnm) and post barite-type (P212121) structures are mechanically and dynamically stable at 27 GPa indicating that the monazite-type (P21/n) → barite-type (Pbnm) phase transformation may be hindered by a kinetic barrier. The phase transformation in monazite-type LaPO4 is driven by a softening of the C25 single crystal elastic constant. Moreover, a small displacement and tilting of PO4 tetrahedra as a function of pressure leads to a change in the La chemical environment and creates space for the construction of LaO12 polyhedra from LaO9 due to a phase transformation.

Abstract
AIMS The aim of this research was to evaluate the impact of early clinical exposure on the learning experiences of undergraduate dental students. METHODS This study was based on mixed methods. The first phase involved administering a purposely designed questionnaire consisting of 16 items, grouped into three subscales. The second phase of the research was conducted using qualitative semi-structured interviews to explore the perceptions and experiences of stakeholders regarding early clinical exposure. RESULTS In total, 134 undergraduate dental students and eight clinical supervisors responded to the questionnaire and reported positive perceptions regarding the learning experiences, professional relationship and learning environment. Qualitative interviews were conducted with 12 participants, and early clinical exposure was perceived to be useful in providing a context to theoretical learning and development of interpersonal skills. Curriculum overload and further need for consolidation were highlighted as the main challenges. CONCLUSIONS This study provided insights into the clinical training model in an undergraduate dental programme and highlights the benefits and challenges of early clinical exposure in the study population. The study served as a vehicle for engagement with a range of stakeholders using a mixed methods approach to inform further development of the training model.

Abstract
Punica granatum L. (wild) belongs to family Punicaceae, a woody plant, predominantly found on calcareous and alkaline soils. The species is extensively utilized as food and firewood and for the extraction of various chemicals due to its therapeutic properties. To understand the ethno-botanical and ecological status of the species on a regional scale, a questionnaire survey was conducted in the Dir (L) area using close and open-ended questionnaires. Data collected from 124 respondents were analysed quantitatively using statistical analysis to calculate indices like Relative Frequency of Citation (RFC), Use value (UV) and multivariate analysis. GPS data used for the presence data of the plants were used to develop GIS thematic maps. Geo-referenced data on P. granatum was collected from the study area, using GPS. Results suggest that the plant is mostly used as a remedy for dry cough, as an astringent, people used powder form of fruit peelings. It was documented in the present investigation that P. granatum is mainly eradicated due to its extensive use as firewood. The study also evaluated on the major aspect of how the P. granatum can be conserved naturally. It was found out that the plant is conserved in areas inaccessible to humans. The status of the vegetation community around this plant was also explored, it is found out that specific shrub and tree communities were major flora growing in proximity to P. granatum. The finding of this survey has concluded that wild P. granatum is an endangered species due to its extensive and uncontrollable use for firewood, curing diseases and its economic potential. These findings could be exploited to take necessary steps for the conservation of this species.

Abstract
AIMS To compare the academic performance of graduate-entry and direct school leavers in an undergraduate dental programme. METHODS This study examined the results of students in applied dental knowledge (ADK) progress tests conducted during two academic years. A mixed model analysis of variance (ANOVA) was conducted to compare the performance of graduate-entry and direct school leavers. ADK was treated as a repeated measures variable, and the outcome variable of interest was percentage score on the ADK. RESULTS The results show statistically significant main effects for ADK [F (1,113) = 61.58, P < 0.001, η2p = 0.35], Cohort [F (1,113) = 88.57, P < 0.001, η2p = 0.44] and Entry [F (1,113) = 11.31, P = 0.001, η2p = 0.09]. That is, students do better on each subsequent test (main effect of ADK), students in later years of the programme perform better than those in earlier years (main effect of cohort), and graduate-entry students outperform direct school leavers. CONCLUSIONS This is the first study to explore the differences in the academic performance of graduate-entry and direct school leavers in an undergraduate dental programme. The results show that the academic performance of graduate students was better than the direct school leavers in years 2 and 3. Further research is required to compare the performance of students longitudinally across the entire duration of undergraduate dental programmes and evaluate whether this difference persists throughout.

Abstract
AIMS The aim of this study was to develop a valid and reliable scale to measure preparedness of new dental graduates. METHODS The scale development and validation was carried out using the Rasch measurement model. Following a pilot and pre-testing of the scale, a national study was undertaken with undergraduate students from all dental schools as well as foundation dentists in UK. RESULTS To examine the internal validity of the scale, we conducted a Rasch analysis. External validity of the scale was checked through validation with a range of stakeholders. An excellent fit to the Rasch model provided evidence of internal construct validity. The scale demonstrated invariance, ordered thresholds and lack of differential item functioning. Unidimensionality of the scale was confirmed by independent t-tests. The PSI value was 0.877, indicating a good degree of person separation and internal consistency. Test-retest reliability of the scale was also established. CONCLUSIONS The preparedness scale developed in this project reflects innovative research using a systematic approach and employment of modern psychometric methods. The scale can be used for assessment of the preparedness of undergraduate students by dental educators and potential employers as well as by the student for self-assessment.
