Purpose: To study the degree of accuracy in gingival shade matching of undergraduate students using a computer application. Materials and Methods: In total, 76 undergraduate dental students' gingival shade-selection abilities were evaluated using an in-house developed computer application. A total of 15 intraoral gingival photographs and 21 pink gingival color porcelain samples were used. The environmental conditions were standardized, and no time limit was set for answering in the computer application. Results: Fourteen gingival color samples (66.6%) were not useful for representing the studied gingival shades. Not all natural gingival colors studied were represented within the 50.50% acceptability limits of the pink samples. There were no statistically significant differences between men and women in terms of "hit" percentages. The highest correlation coefficient (in absolute value) was for the L* coordinate (the darker the gingiva in the picture, the higher the hit rate for choosing the "ideal" shade tab); however, none of the linear correlation coefficients were statistically significant. Conclusions: Not all colors provided in the pink ceramic system were useful for subjective gingival selection. There were no statistically significant differences between male and female dental students in gingival color perception. The L* coordinate was the only one that influenced the correct perception of gingival color by dental students, and it did so more in women than in men. [ABSTRACT FROM AUTHOR]

Purpose: To compare volumetric changes in buccal soft tissue and pink esthetic scores after immediate implant placement performed with a socket shield technique (SST) or the conventional technique (CT). Materials and Methods: This parallel-arm, randomized controlled trial included 22 participants requiring replacement of a single maxillary incisor with an immediate implant. Immediate implants were placed via either the SST or the CT, with patients randomly allocated to one of the two groups. All implants underwent an immediate loading protocol. Definitive crowns were placed 6 months after implant placement. Scans of casts were recorded with a digital white light scanner before implant placement and at the end of 12 months. Volumetric changes to soft tissues on the buccal aspect were assessed by superimposition of the scanned cast. Esthetic evaluation of the soft tissue was done by evaluating the pink esthetic score (PES) before implant placement and 6 and 12 months after implant placement. Statistical analysis of the data was performed using statistical software (Stata 16.0, StataCorp). Results: The mean volumetric change in buccal soft tissues at the end of 12 months in the SST group was -0.1520 ± 0.86 mm, and in the CT group, it was -0.643 ± 0.35 mm. The difference was statistically significant (P = .001). Higher PES was observed in the SST group at all time intervals. The difference was statistically significant at 6 months (P = .001) and 12 months (P = .007). Conclusions: The results of this study showed less volumetric changes in buccal soft tissues and higher PES when the SST is used rather than the CT. [ABSTRACT FROM AUTHOR]

A networked supramolecular logic AND gate system is accomplished using precise chemical communication within a multicomponent ensemble via metal ion‐driven self‐sorting processes. The cybernetic AND gate is composed of a copper(I)‐loaded nanoswitch, an aza‐crown ether and a rhodamine receptor. The modus operandi of the AND gate, from state (0,0), was induced with stoichiometric amounts of two inputs (IN‐1=Hg2+, IN‐2=Li+) generating copper(I) ions as output only in state (1,1). Generation of state (1,1) from state (0,0) involves selective Cu+ ion translocation from the nanoswitch to the aza‐crown ether in the first step (IN‐1) and then from the aza‐crown ether to the rhodamine receptor in the second step (IN‐2). The released copper(I) output acts as a messenger that binds to the rhodamine receptor, triggering it's spiro‐lactam ring opening, which leads to a diagnostic FRET emission from the copper(I)‐loaded rhodamine scaffold accompanied by a remarkable fluorescence and colour change from pale yellow to pink.

Melanosis in seafood is a natural post-mortem enzymatic process that results from the action of polyphenol oxidase from the animal’s own tissues. It reduces the organoleptic quality of the shrimp and their commercial value. This work concerns prevention of melanosis in pink shrimp (Parapenaeus longirostris) using the latest technology of enzymatic biosensor for sulphite detection. Three application methods (dipping, dusting, and spraying) with four commercial products were tested. Sulphite concentrations (1–3%) were applied for 1–10 min. Parameters measured included residual SO2 levels, pH, melanosis, and odour. Findings showed that the dusting method gave the best sensory scores, but had harmful residual SO2 values. The dipping method provided safe SO₂ levels below normative limits, when using products with 240 g Kg−1 SO₂ content applied at 1.25% bisulphite/seawater for 1 minute. Regarding the spraying method, the results remain promising. Nevertheless, further studies are necessary to understand its potential and limitations fully. [ABSTRACT FROM AUTHOR]

Objective: To design a specific advanced life support (ALS) tape based on recent Indian multicenter height/length and weight data to accurately estimate the weight from the recumbent length. Methods: We designed the new ALS tape by matching the median weights to median heights/lengths from the recently published Indian multicenter growth data, maintaining the same color codes as the Broselow tape. The accuracy of weight estimation for the newly designed ALS tape was validated and compared with the Broselow estimated weights at a tertiary care hospital. Results: The color (weight) band matched median heights (cm) from the new ALS tape were higher (53.9 vs 53.0 for grey, 67.4 vs 63.1 for pink, 76.4 vs 70.6 for red, 85.5 vs 79 for purple, 95.5 vs 89.6 for yellow, 107.5 vs 101.9 for white, 130.5 vs 126.1 for orange and 140.5 vs 137 for green) than the Broselow tape. For every color band on the newly designed ALS tape, a sizable proportion of children (27% for grey, 78% for pink, 83% for red, 38% for purple, 63% for yellow, 41% for white, 35% for blue, 54% for orange) recorded a higher Broselow color band, suggesting overestimated weights at each color band. The percentage difference in the estimated weight from the actual weight was very small (−0.5% for under-5 years and −0.2% for older children) using the new ALS tape as compared to Broselow tape. Conclusion: This Indianized ALS tape estimated Indian children's weights more accurately. Use of the newly designed ALS tape may reduce the errors in calculating emergency medications, fluids and equipment sizes. Further studies are required to validate this tape in pediatric emergency departments in India. [ABSTRACT FROM AUTHOR]

Objectives Materials and Methods Results Conclusion This study aimed to report the clinical and radiographic results of 2.8 mm two‐piece narrow diameter implant (NDI) supporting fixed restorations.Clinical and radiographic data of 54 NDIs in 32 patients were retrospectively assessed after 2 to 11 (mean 8.17) years of follow‐up. Clinical and radiographic measurements were taken. Survival rate, implant and prosthesis failure, pink aesthetic scores (PES), white aesthetic scores (WES), bleeding on probing (BOP), probing depth (PD), marginal bone loss (MBL), and mechanical and biological complications were evaluated.An implant failed during the follow‐up period, resulting in a cumulative survival rate of 98.15% at the implant level and 96.88% in the patient. The total mean values of PES and WES for 2.8 mm NDIs were 7.09 ± 1.15 (range: 3.33–9.00) and 7.42 ± 1.03 (range: 3.67–9.33). The prevalence of sites with positive BOP was 38.14 ± 29.77%. The mean PD value was 2.46 ± 0.62 mm. The average MBL was 1.15 ± 0.74 mm (range: 0.25–4.03 mm). No implant or abutment fracture was detected. A veneer chipping was present in one patient, and a loose crown appeared in another patient. Two implants (3.7%) and two patients (6.3%) were diagnosed with peri‐implantitis.Within the limitation of the study, the results indicate that the use of two‐piece 2.8 mm NDI for the fixed prosthetic rehabilitation of edentulous regions with reduced interdental and/or buccal–lingual width is viable.

In order to study the effect of impurity iron in different valence states on the coloration mechanism of quartz, colorless synthetic quartz fabricated via ion implantation and its natural counterpart citrine with iron were compared after heating under different atmospheres. Ultraviolet-visible spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, electron paramagnetic resonance spectroscopy, and Fourier transform infrared spectroscopy were used to analyze the absorption property, valence states of iron, and type of O of both natural citrine and ion-implanted quartz. Experimental results showed the yellow color in quartz was mainly related to the charge transfer between Fe3+ and Fe2+, oxygen vacancies and the lattice oxygen, whereas the pink color in quartz was related to oxygen vacancies at a high temperature of 1200 °C.

Introduction: In reverse shoulder arthroplasty (RSA) new designs enable greater amounts of lateralization to prevent instability and scapular notching and increase range of motion, however, excessive lateralization leads to stress upon the acromion that can result in scapular spine fatigue fractures. Aim of this study was to gender- and size-specifically assess the influence of glenosphere size and different humeral designs on lateralization, distalization, and bony impingement-free range of motion (ROM) in patients undergoing RSA. Methods: Computed tomography scans from 30 osteoarthritic patients (f:15, m:15) and 20 cuff tear arthropathy patients (f:10, m:10) were used to virtually simulate RSA implantation. The efficacy of an inlay Grammont-type system vs. an onlay lateralizing system combined with different glenosphere sizes (36 mm vs. 42 mm) in achieving ROM, lateralization, and distalization was evaluated. Moreover, gender and patient's constitution were correlated to humeral size by radiologically measuring the best-fit circle of the humeral head. Results: A different amount of relative lateralization was achieved in both genders using large glenospheres and onlay designs. Latter yielded a higher ROM in all planes for men and women with a 42 mm glenosphere; with the 36 mm glenosphere, an increased ROM was observed only in men. The 155° inlay design led to joint medialization only in men, whereas all designs led to lateralization in women. When adjusting the absolute amount of lateralization to humerus' size (or patient's height), regardless of implant type, women received greater relative lateralization using 36 mm glenosphere (inlay: 1%; onlay 12%) than men with 42 mm glenosphere (inlay: -3%; onlay: 8%). Conclusion: The relative lateralization achieved using onlay design is much higher in women than men. Small glenospheres yield greater relative lateralization in women compared to large glenospheres in men. Humeral lateralization using onlay designs should be used cautiously in women, as they lead to great relative lateralization increasing stress onto the acromion. Level of evidence: Basic Science Study, Computer Modeling. [ABSTRACT FROM AUTHOR]

To broaden the applications of yttria‐stabilized zirconia (YSZ) in mobile phone back panels and high‐end decorative materials, the 3 mol% YSZ (3YSZ) ceramics doped with erbium oxide (Er2O3) as colorant were successfully sintered at 1250 and 1350°C in air. The influences of Er2O3‐doping concentration and sintering temperature on the phase, microstructure, color, and mechanical properties of the pink Er2O3‐3YSZ ceramics were investigated. As the Er2O3 concentration increased, the redness value a* gradually increased, while the yellowness value b* and the lightness value L* gradually decreased. The highest value a* and b* of Er2O3‐3YSZ ceramics reached absolute values of 15.2 and 4.5, respectively. The effect of Er2O3 concentration is also depicted in detail, which also affects the mechanical properties including hardness and fracture toughness of the ceramics. The maximum hardness and fracture toughness of Er2O3‐3YSZ ceramics reached 13.9 ± 0.3 GPa and 6.21 ± 0.20 MPa·m1/2, respectively. The hardness of the ceramics exceeds 12.5 GPa, which is the required market index for further practical application. This work provides a method for preparing 3YSZ ceramics with excellent mechanical properties and bright pink color, which has the potential to be used in the fields of advanced and superior electronics in particular.

A taxonomical study of Sobralia decora and allied species recorded in South America is presented. The group is characterized by light pink to purple flowers, often with a white tip of the labellum and yellow to brown area on its throat. If considering the habit, the species can be recognized and distinguished from all other Sobralia species by producing keikis–stems arising from the old inflorescence. The similarity of the species forming the discussed complex caused numerous mistakes noticed in the literature and among the herbarium specimens. The aim of the elaboration is to clarify the differences allowing to determine the living and herbarium specimens with no errors. [ABSTRACT FROM AUTHOR]

This article adopts the combined perspectives of critical discourse studies and (critical) intersectionality studies to examine efforts at movement-building by Pink Dot SG, an LGBTQ group, which has developed within the illiberal geopolitical space of Singapore. The term 'intersectionalisation' is introduced to refer to a reflexive meta-discursive strategy which mobilizes the intersectionality of social identities (such as gender, sexuality, race, class, generation, and nationality) to advance particular sociopolitical objectives. The article illustrates three ways intersectionalisation operates in Pink Dot's official videos: (i) to create solidarities within the LGBTQ community; (ii) to advocate for the LGBTQ community by straight allies, and (iii) to forge alliances dialogically between queer and straight communities in Singapore. The analysis of the videos shows that interactions between various assemblages of intersectional identities of privilege and marginality are brought to the fore in building the social movement, and how its discourse navigates a terrain of complicated power dynamics.

Due to the lack of other treatment options, a rebirth of polymyxins is urgently required. Colistin (also called polymyxin E) and polymyxin B are the only two examples of this antibiotic class that were effectively employed in such critical situations. In the present work, both of the two studied medications were quantified via a simple, green, and non-extracting spectrophotometric approach based on the formation of ion-pair complexes with Erythrosine B. Without using any organic solvents, the pink color of the created complexes was detected at wavelength = 558 nm. To achieve the highest intensity of absorbance, optimum conditions were established by the screening of many experimental factors such as pH, buffer volume, the volume of Erythrosine B, and the time consumed to undergo the reaction. For Colistin and Polymyxin B respectively, Beer-Lambert's law was observed at the concentration ranges of 1–6, 1–9 µg mL− 1. The technique was approved and validated following ICH recommendations. Lastly, the suggested approach has been successfully implemented to quantify the cited medications colorimetrically, for the first time, in their parenteral dosage forms with excellent recoveries. Also, Content uniformity testing was implemented. [ABSTRACT FROM AUTHOR]

AbstractWhen Canadian broadcaster, Lisa LaFlamme, announced in August 2022 that CTV National News did not renew her contract, some observers suggested that the corporation’s decision resulted from LaFlamme’s choice to “let her hair go gray” during the pandemic. An international public outcry ensued on Twitter. Our study involved an examination of these tweets (n = 440). Analyses revealed that approximately 80 percent of tweets indicated opposition to LaFlamme’s dismissal, while only 2 percent indicated support and 18 percent indicated a neutral position. Among tweets expressing opposition, the most common justification, found in 79 percent of these tweets, centered on assessments of the employer’s decision as poor. The frequency of all other justifications for opposition was considerably lower, with only 26 percent of these tweets mentioning ageism, 22 percent mentioning sexism, and 20 percent mentioning a general sense of unfairness to LaFlamme. These findings suggest the salience of capitalist logics in shaping how the public frames gendered ageism in the workplace. Our analyses also suggest a view of responses to this inequality as personal bodywork choices. Together, these framings reflect a more individual- than structural-level critique of gendered ageism, knowledge of which can inform efforts to dismantle it. [ABSTRACT FROM AUTHOR]

Background: Skin "yellowness" is an abstract and subjective term, without a definitive measurement protocol. Objectives were to analyze Chinese women's self‐perception of skin yellowness and associated parameters and identify objective clinical measurements that correlate with these perceptions. Methods: Following focus group discussions, criteria for skin yellowness were defined, and validated by volunteer rankings of facial images. A typology study of 185 women was performed. Participants were grouped into yellow (Color Uniformity, Brightness and Transparency (CUBT) yellow scale grade > 3, chromameter b* value > 16) and non‐yellow (CUBT yellow scale grade < 2, b* value < 14) groups. Participants self‐evaluated their skin on yellowness, transparency, skin uniformity, dullness, radiance, oiliness, and texture. Expert assessments were performed to grade sebaceous pores, ocular area pigmentation, pigmentary spots and CUBT scores. Instrumental analysis of the skin was employed using corneometer, sebumeter, mexameter chromameter, and AGE reader. Results: Women in the yellow group self‐evaluated their skin as significantly duller, less uniform, and less radiant than women in the non‐yellow group (P ≤ 0.05). Higher levels of ocular area pigmentation and lower facial skin uniformity and brightness (P < 0.001) were observed in women with yellow skin. CUBT expert grading showed lower pink skin color, but significantly higher beige, yellow, and olive pigmentation (P ≤ 0.05) in women in the yellow skin group. Melanin and b* values were significantly higher in women with yellow skin while L value was significantly lower. Conclusion: Self‐perceived skin yellowness in Chinese women correlates to chromameter and mexameter measurements, as well as expert evaluation of ocular pigmentation and CUBT parameters.

Restoring native plant species on degraded landscapes is challenging. Symbiotic partners in the plant rhizosphere can aid in nutrient acquisition, pathogen protection, stress tolerance, and many other processes. However, these microbes are often absent in altered landscapes and need to be re-integrated to improve restoration efforts. We evaluated, within a laboratory setting, the ability of commercial and indigenous rhizobia strains to form nodules on lupine species used for rangeland seedings in the Great Basin region of the Western United States and ascertained if these strains could be applied through a seed coating. We also evaluated if a compost amendment applied via seed coating could further enhance the performance of the rhizobia strains. Our analysis showed that successful nodulation could occur using commercial and wildland-collected indigenous strains through either a liquid culture applied to seedlings or as a dry seed coating. However, the number of root nodules and the presence of a pink color (indicating nitrogen fixation) were typically higher in the commercial product than in the indigenous strains. Compost did not improve nodulation or the performance of the nodules; however, this treatment alone improved shoot growth. Overall, these results suggest that commercial rhizobium may be more effective in improving plant growth, and future research with native rhizobia may want to consider identifying strains compatible with seed-coating delivery. Longer-term studies are now merited for assessing how the rhizobia strains evaluated in this study influence plant growth, particularly in a field setting. [ABSTRACT FROM AUTHOR]

Temporary immersion system (TIS) cultures are reported to be superior when compared to semi-solid (SS) and liquid (LQ) cultures for the in vitro plant regeneration of many plant species. In the present study, we used a TIS for plant regeneration of Gerbera jemesonii "Shy Pink" and compared the results with that of SS and LQ cultures. The number of shoots regenerated in the SS, LQ, and TIS cultures was 6.93, 3.13, and 3.03, respectively. The shoots regenerated with the SS and LQ cultures demonstrated 3.33 and 4.22% hyperhydricity, whereas the shoots regenerated with the TIS were healthy even though the number of shoots regenerated was less. The plantlets regenerated with the TIS demonstrated higher values for the number of roots, root length, biomass of the plantlets, leaf length/width, and area compared to the SS and LQ cultures. When the G. jemesonii "Shy Pink" plants were regenerated using the TIS, their levels of photosynthetic pigments were highest. The number of stomata on the abaxial surface of their leaves was 11.40, and the frequency of closed stomata was 59% for the plants regenerated with the TIS. The number of stomata was 21.4 and 14.5 for the plants regenerated with the SS and LQ cultures, respectively. Meanwhile, the frequency of closed stomata was 13% and 15% for the plants regenerated with SS and LQ cultures. Furthermore, G. jemesonii "Shy Pink" showed the highest survival of plants when regenerated in the TIS compared to SS and LQ cultures. The TIS was found to be the most suitable culture system for plant regeneration of G. jemesonii "Shy Pink" compared to SS and LQ cultures. [ABSTRACT FROM AUTHOR]

In the survey of biodiversity of actinobacteria associated with mosses (Taxithelium nepalense (Schwägr.) Broth. and Barbula indica (Hook.) Spreng.), certain strains of pigment producing actinobacteria were isolated and purified on SCA and incubated at 30°C for 1 week. Based on deep-shade color of actinobacterial pigments, 4 strains were collected and used for painting color preparation. To evaluate the antimicrobial activities, the crude extracts were prepared from 4 actinobacterial strains and tested with Escherichia coli PSRU-01 and Staphylococcus aureus PSRU-01. The results indicated that the crude extracts of C7, C13, C15 and D13 could not inhibit growth of E. coli PSRU-01, but S. aureus PSRU-01 was inhibited. Two fungal testers, including Colletotrichum sp. PSRU-01 and Fusarium sp. PSRU-01, were completely inhibited by the crude pigment extracts of C13, C15 and D13. Based on phylogenetic results, the actinobacterial strains were closely related to Streptomyces californicus (C7, 100% identity), Streptomyces bungoensis (C13, 99.8% similarity), Streptomyces humi (C15, 99.9% similarity), and Streptomyces rectiverticillatus (D13, 99.8% similarity). They also shared phenotypic characteristics with Streptomyces. The cultivated cells of actinobacteria on broken-milled rice were used for pigment extraction and followed by determination of the extracted pigments for mixing with acrylic color in the shade violet, green, orange and pink colors. Application of actinobacterial pigments in painting is the first report and it is an innovative utilization of actinobacterial pigments in non-scientific field in Thailand. [ABSTRACT FROM AUTHOR]

BACKGROUND: An attempt has been made to explore the nutritional profile of pink oyster mushrooms that have been grown in various agricultural residues, including sugarcane bagasse, rice straw, coconut coir and sawdust, along with other nutrient supplements such as defatted mustard and chickpea powder, for appropriate growth and fruiting body formation in a short span of time. The spawn production was experimented with five different grain varieties. The study became interesting when the observations differed slightly from the traditional practices, with the addition of defatted mustard supplements resulting in a positive correlation with respect to reducing the fruiting time, as well as improving yield and the nutritional profile of Pleurotus djamor. RESULTS: An elevated yield of 651.93 g kg−1 was recorded in the medium where the RS and DM were used in the ratio of 1:0.01 (rice straw +1% w/w defatted mustard) bag, whereas, in terms of protein content, a maximum yield of 32.57 ± 0.79 mg g−1 was observed when SB:DM was in the same ratio (sugarcane bagasse +1% w/w defatted mustard) bag. CONCLUSION: To confer the best outcomes from the screened substrates, a series of experiments were performed by varying the concentration of RS and SB, with 1% w/w DM. It is worth noting that the highest protein content of 32.76 ± 0.38 mg g−1 was obtained along with the total yield of 702.56 ± 2.9 g kg−1 of mushroom when the ratio of RS:SB was 0.7:0.3. © 2024 Society of Chemical Industry.

Hands-on training is a crucial part of education in neuroendovascular treatment to ensure safe and rapid acquisition of techniques. However, there is a significant gap between training and actual clinical practice. This study will introduce innovations for more practical thrombus retrieval training that was developed in this process. A Smart Vascular Model 3 in 1 was used. A pink pseudothrombus was inserted into the M1 (horizontal segment of the middle cerebral artery) section of the model. Then, a "red underlay" purchased at a stationery store was placed to cover the proximal part of M1 and beyond so that the pseudothrombus was not visible. The thrombus was retrieved during training by looking for the location of the thrombus based on the behavior and resistance of the tip of the guidewire and deployment of the stent retriever. The participants were required to have detailed observation skills and precise manipulation skills using a red film to prevent the direct visualization of the pseudothrombus. The implementation of this innovation to the previous hands-on training made the training more practical and effective. If the exact thrombus location can be determined by the behavior of the wire tip, the device's capabilities can be maximized, and rapid retrieval can be expected. It could also reduce complications, as unnecessary peripheral guidance of the device could be avoided. [ABSTRACT FROM AUTHOR]

Hexavalent chromium (Cr(VI)) is a hazardous metallic compound commonly used in industrial processes. The liver, responsible for metabolism and detoxification, is the main target organ of Cr(VI). Toxicity experiments were performed to investigate the impacts of low-dose exposure to Cr(VI) on rat livers. It was revealed that exposure of 0.05 mg/kg potassium dichromate (K2Cr2O7) and 0.25 mg/kg K2Cr2O7 notably increased malondialdehyde (MDA) levels and the expressions of P-AMPK, P-ULK, PINK1, P-Parkin, and LC3II/LC3I, and significantly reduced SOD activity and P-mTOR and P62 expression levels in liver. Electron microscopy showed that CR(VI) exposure significantly increased mitophagy and the destruction of mitochondrial structure. This study simulates the respiratory exposure mode of CR(VI) workers through intratracheal instillation of CR(VI) in rats. It confirms that autophagy in hepatocytes is induced by low concentrations of CR(VI) and suggest that the liver damage caused by CR(VI) may be associated with the AMPK-related PINK/Parkin signaling pathway.

Gingiva hyperpigmentation resulting from physiological melanosis causes aesthetic discomfort and is usually perceived as a disease by patients because healthy attached gingiva is typically characterized by coral pink coloring with stippling and scalloped contours. When physiological melanosis compromises the aesthetics of smiling, it may induce insecurity in patients, who usually seek out alternatives for reducing or eliminating hyperpigmentation. We present a case report of a surgical procedure combining gingivectomy with gingivoplasty for the management of physiological melanosis. The surgical procedure was performed on a 40-year-old female patient with bilateral pigmentation in both arches. The results of the histological analysis confirm the diagnoses of melanotic macula, with papillary hyperplasia and cytopathic changes being suggestive of HPV infection, which was verified using an immunohistochemistry analysis based on the detection of a major capsid protein of HPV. Acceptable functional and aesthetic results were obtained for the patient without major discomfort during the postoperative period. In cases when HPV infection is present, long-term follow-up becomes necessary. [ABSTRACT FROM AUTHOR]

The management of the aesthetic parameter represents an important factor in the integration of removable prostheses. The current major social interest in beauty has made patients more and more demanding with regard to their appearance. [1] The main objective of this study was to assess the aesthetic expectations of patients with removable prostheses at the CHU-CNOS in Bamako. Our prospective and descriptive study having collected 78 patients was carried out over a period from March 2, 2019 to March 9, 2020 at the removable prosthesis department of the CHU-CNOS in Bamako. The female sex represented 55.1% with a sex ratio of 0.65. Removable prosthetic rehabilitation mainly concerned young adults aged 21-41 (41%) Aesthetics was the main reason for rehabilitation most represented with 60.3% of cases. The white tooth was the most requested dental shade with 70.5% of cases Bonded teeth were the most represented in our patients with 71.79% of cases. Pink gum was the shade most requested by our patients with 43.6% of cases. Obtaining a personalized prosthesis in harmony with the facial framework, giving the illusion of naturalness and restoring the smile to patients is the objective to be achieved.

Simple Summary: Galápagos pink land iguanas (Conolophus marthae) are a critically endangered species endemic to Wolf Volcano, Galápagos. Among other conservation initiatives, a head-start program, involving the captive rearing of hatchlings prior to release in the wild, has been identified as a primary action needed to prevent the species' extinction. However, until this study began, the location of pink iguana nesting grounds was unknown, and no hatchlings and only a handful of juveniles and subadults had been observed. In an attempt to unveil the location of nesting grounds for C. marthae, we modeled the movement patterns of male and female iguanas tracked during the reproductive season. Based on the hypothesis that males and females might exhibit different movement patterns after the breeding season, we looked for females-specific migratory behavior. Thanks to this approach, we identified an area that females likely use to nest. Our results based on movement data alone led to the first-ever identification of pink iguana nests and hatchlings. Invasive alien species control is recognized worldwide as a priority action to preserve global biodiversity. However, a lack of general life history knowledge for threatened species can impede the effectiveness of conservation actions. Galápagos pink land iguanas (Conolophus marthae) are endemic to Wolf Volcano, Galápagos, Ecuador. These iguanas are threatened by invasive alien species, particularly feral cats, that may affect their small population size. To guarantee the long-term survival of C. marthae, the Galápagos National Park Directorate is considering, along with an ongoing campaign of feral cat control, the implementation of a head-start program. However, the success of this management strategy necessarily relies on the identification of pink iguana nesting grounds, which were still unknown at the onset of this study. We modeled the movement patterns of male and female iguanas during the reproductive season, using location data collected from custom-made remote tracking devices installed on adult pink iguanas in April 2021. We first calculated for each individual the vector of distances from its starting location, which was defined as net displacement. We then used net displacement as the response variable in a generalized additive mixed model with day of the year as the predictor. Based on the hypothesis that males and females may behaviorally differ after mating, we looked for female-specific migratory behavior suggesting females were moving toward nesting areas. The results obtained confirmed our hypothesis, as females exhibited a distinct migratory behavior, reaching a small plateau area inside of Wolf Volcano's caldera and ca. 400 m below the volcano's northern rim. Moreover, once inside the caldera, females displayed a more aggregated distribution pattern. The movement data obtained allowed Galápagos National Park rangers to locate individual pink iguana nests and subsequently to sight and collect the first observed hatchlings of the species. This work constitutes a necessary baseline to perform dedicated studies of pink iguana nests and emerging hatchling iguanas, which is an essential step toward the development of an effective head-start program.

This article provides an update on a study of foreign pottery found at the temple of Tausert in Egypt. The pottery recovered during the 2013-2015 seasons includes vessels from the Levant, the Aegean, Lower Egypt, and the Western Desert oases. The article discusses three chronological eras of foreign pottery found: Byzantine, Late Period with Phoenician imports, and late New Kingdom with imports from the Levant, the Aegean, and the oases. The distribution and characteristics of the pottery provide insights into the history and activities at the temple of Tausert. Additionally, the document provides information about Oasis Ware, a type of ceramic vessel used to transport wine from the Western Desert oases, which was highly valued by the elites in Egypt.

The aim of this study was to compare the quality of plain yogurt made from cow milk (n = 10) and its plant-based analog made from coconut flesh extract (n = 14). Coconut yogurt alternatives were divided into 2 experimental groups based on differences in their color, which were noted after the packages had been opened. The first group included products with a typical white color (n = 8), and the second group comprised products with a grayish pink color (n = 6) that developed as a result of oxidative processes. In comparison with its plant-based analog, plain yogurt was characterized by higher values of lightness (L*), yellowness (b*) and chroma (C*), higher titratable acidity, a higher content of retinol and α-tocopherol, higher nutritional value of fat, and lower values of water-holding capacity (WHC) and redness (a*). Plain yogurt had lower volatile acidity than its plant-based analog with a grayish pink color. A comparison of yogurt analogs with different colors revealed that the product with a grayish pink color was characterized by a lower value of L*, and higher values of a*, b*, C*, and pH. An analysis of its fatty acid profile demonstrated that it also had a higher proportion of C14:0 and C18:1 cis -9; higher total monounsaturated fatty acids content; a lower proportion of C10:0, C12:0, and C18:2; a lower total content of polyunsaturated fatty acids (PUFA) and essential fatty acids; and a lower ratio of PUFA to saturated fatty acids. The yogurt analog with a grayish pink color had a lower total content of tocopherol isoforms than the remaining products. The yogurt analog with a white color had the highest WHC and γ-tocopherol content. Consumers should be aware of the fact that coconut yogurt alternatives may have nonstandard quality attributes. The differences between such products and yogurt made from cow milk should be explicitly communicated to consumers so that they could make informed purchasing decisions. [ABSTRACT FROM AUTHOR]

Fe-dominant sogdianite, a cyclosilicate compound with the chemical formula (Fe3+0.74Zr0.64Ti0.46 Al0.15)(□1.02Na0.98)K[Li3Si12O30], was studied. The investigation involved a comprehensive analysis of the mineral sample, including crystal-chemical analysis, Raman and FTIR spectroscopy, optical absorption, and luminescence study. Crystallographic site populations were determined through single crystal structure refinement and electron probe microanalysis. The thermoelastic behavior of a powder was studied using in situ high-temperature X-ray diffraction (30–750 °C). Notably, no phase transition was detected; sogdianite exhibited anisotropic thermal expansion. The first time study of vibrational spectra and spectral bands assigning were performed. The electronic transitions in d5-ion impurities of sogdianite were studied using optical absorption and luminescence spectroscopy. The origin of pink color and luminescence of sogdianite was clarified. The broad spectral bands in the visible UV spectral region are responsible for the pink color exhibited by sogdianite and could be attributed to d–d transitions occurring in Fe3+ ions.

Pink pepper is classified into the Californian/Peruvian type (Schinus molle) and the Brazilian type (S. terebinthifolia). According to studies, pink pepper extracts and essential oils have shown anti-inflammatory, antioxidant, genotoxic and antidiabetic properties in in vitro and in vivo studies. The results of bioactivity tests vary depending on the geographical origin of the pepper. In this paper, the cytotoxic, antioxidant and antibacterial effects of the essential oil of the commercial pink pepper fruit from the Tuzla market were investigated. To assess the cytotoxic potential, a tetrazolium salt reduction (MTT) viability assay was performed. The antioxidant potential was examined spectrophotometrically, using DPPH and FRAP methods. Diffusion techniques were used to evaluate the antibacterial activity of the essential oil. Using GC/MS, 24 components of red pepper essential oil were identified, of which α-pinene, α-phellandrene, δ-3-carene and D-limonene dominate. The studied pink pepper essential oil inhibited the cell proliferation in the HeLa cell line, causing a dose-dependent cytotoxic effect (IC50=389.46 µg/mL). The essential oil inhibits DPPH radicals. The reducing ability is relatively weak. For the essential oil, an extremely good ability to inhibit the growth of the bacteria used in this study was confirmed. These results indicate a very high potential of essential oil of pink pepper fruit as an inhibitor of pathogenic organisms. [ABSTRACT FROM AUTHOR]

The article discusses the diagnostic challenges of Atypical Spitz Tumor (AST), a rare melanocytic lesion that can be mistaken for spitzoid melanoma. The use of Line-field confocal optical coherence tomography (LC-OCT) is introduced as a non-invasive technique to aid in distinguishing AST from benign Spitz nevus, particularly in pediatric patients. LC-OCT provides 3D reconstructions of the skin at cellular resolution, highlighting architectural disorder and cytological atypia within melanocytic nests. Further studies are needed to differentiate AST from other entities, and patient consent was obtained for the publication of case details. [Extracted from the article]

The article discusses two new insect species found in Britain. The first is Tischeria ekebladella, a leaf miner that was discovered on a Lucombe oak tree in Shropshire. This is an unusual food choice for the species, and further research is needed to determine if it uses this tree more widely. The second species is Hypsopygia nostralis, a pyralid moth that was found in London. This species has a wide distribution in the southeastern USA and has been introduced to various other locations worldwide. The moth was likely brought to Britain through importation, and its larvae feed on dried organic material, including thatching material made from Sabal Palm leaves. [Extracted from the article]

Thermal conductivity κ (T) of single-crystal CVD diamond lightly doped (about 3 ppm) with nitrogen has been measured at temperatures from 5.7 to 410 K. The sample was carefully characterized by optical absorption and photoluminescence spectroscopy for the presence of impurities. Nine different optically active defects related with nitrogen, hydrogen, and silicon impurities have been identified and quantified. This pink-tint crystal showed a high thermal conductivity of 24.0 ± 0.5 W cm − 1 K − 1 at room temperature, which is very close to the highest value ever measured at about 25 W cm − 1 K − 1 for diamonds of natural isotopic composition. At the same time, the κ (T) of the crystal showed strong suppression > --> 10 % at temperatures 6 < T < 120 K with a maximum decrease of 2.7 times at ≈ 40 K compared to high purity diamonds. This behavior of the conductivity is attributed to a phonon scattering by charge carriers bound to nitrogen-related impurity centers, which is ineffective, however, at room and higher temperatures. The κ (T) has been calculated within the model based on the Callaway theory taking into account the elastic phonon scattering off charge carriers (holes and electrons) in the ground states of doping centers, and a very good agreement between the measured and theoretical data has been achieved. The model also gives a good approximation to the experimental data for κ (T) given in the literature for synthetic and natural single-crystal diamonds. [ABSTRACT FROM AUTHOR]
