Analysis of the Need for Padlet-Based Learning Media Development to Improve Understanding of Concepts in Class XI Circular Motion Material at SMA Kota Bengkulu
Authors: Yulistia Tri
Published: February 2024

An effective learning tool is one that can boost students' interest and motivation. Padlet is an easy-to-use, maintain, and set-up collaborative platform. This study set out to find out what educators and students needed in order to create lesson plans for high school students using the Padlet software. The methodology used in this study was qualitative descriptive. The data was gathered through observations, interviews, and literature research. This research instrument consists of these observation and interview sheets. The technique for data analysis is qualitative descriptive data analysis. The results of the learning materials, interviews, and observations that were done show that there is still space for development in the students' conceptual understanding, especially when it comes to the material on circular motion. because students still find it difficult to understand the material they are studying and professors still use a traditional teaching methodology. Therefore, it can be said that Padlet-based development media are still needed at SMAN 1 Kota Bengkulu, SMAN 3 Kota Bengkulu, and SMAN 9 Kota Bengkulu in order to support students' learning and help them understand concepts. This is based on the needs analysis that was conducted at these schools.

An annotated checklist and bibliography of the land and freshwater snails of México and Central America
Authors: Thompson Fred G.
Published: February 2024

The checklist of the non-marine gastropod fauna summarizes the known species and subspecies that are recognized from México and Central America. It is an annotated list of 1800 terminal taxa presented in a hierarchical framework. These include 1502 native species plus 278 native subspecies, and 20 introduced species. The native species include 175 aquatic operculates, 84 aquatic pulmonates, 130 terrestrial operculates, and 1112 terrestrial pulmonates. In most cases in order to be as objective as possible the list uncritically records the most recent assignment of terminal taxa. In a few instances some changes are deemed necessary. For higher-level changes competing schemes are treated equally. In cases of terminals and higher taxa, readers are directed to the systematic works that discuss relevant taxonomy. It is anticipated that the annotated list will be a useful resource for everyone interested in non-marine gastropods and their nomenclature. In addition to clarifying some issues or points of confusion, this list should also provide an impetus for future work aimed at clarifying and resolving areas of taxonomic disagreement and/or uncertainty, and to make better known the non-marine molluscan fauna of México and Central America.
Decapoda (Crustacea) of the Coon Creek Formation (Maastrichtian) of Mississippi and Tennessee
Authors: Kornecki Krystyna M. , Feldmann Rodney M. , Schweitzer Carrie E.
Published: February 2024

The Upper Cretaceous (Maastrichtian) Coon Creek Formation of Mississippi and Tennessee possesses a diverse and abundant assemblage of decapods including lobsters, ghost shrimp, and crabs. The formation lies in a temporally and paleogeographically significant location, situated between the Atlantic Coastal Plain and the Western Interior Seaway, shortly before the closing of the seaway and the K-Pg mass extinction. Coon Creek decapods have been little studied since the fauna was first described in the 1920s. A large collection of specimens, ranging in preservation from poor to excellent, has recently become available for study. Analysis of the elemental composition of the sediment and cuticle of six species of decapods from six families (Palinuridae, Nephropidae, Callianassidae, Dakoticancridae, Raninidae, and Retroplumidae) collected at the Blue Springs locality in Mississippi reveals phosphatic replacement of cuticle and trace amounts of iron and sulfur in the surrounding sediment. Concretions bearing decapods and a decapod burrow were observed in thin section and were mapped for elemental distribution using Energy-dispersive X-Ray spectroscopy and dot mapping indicating consistent elemental results with the surrounding sediment. The six species of decapods were analyzed using the same techniques and suggest diagentic affects in cuticlar structure and the presence of silica forming on the cuticle of a single specimen. Taphonomic data supports preservation ranging from well preserved phosphatization to secondary alteration to silica-rich exterior and weathering clay minerals. Because the silica is not replacing the phosphatized exocuticle and microscopic structure of cuticle in cross section is not preserved in the silica layer, the cause of this alteration is uncertain. The systematics and taxonomy of the decapod species from the Coon Creek Formation were reassessed. Sixteen species are identified, including two new species: Hoploparia tennesseensis, Hoploparia mcnairyensis, Linuparus keyesi sp. nov., Linuparus sp., Palaeopetrochirus enigmus, Seorsus wadei, Bournelyreidus ericksoni sp. nov., Cristipluma mississippiensis, Lithophylax flectus new combination, Hoploparia georgeana, Mesostylus mortoni, Tetracarcinus subquadratus, Avitelmessus grapsoideus, Cretacoranina testacea, Dakoticancer australis, Prehepatus harrisi, and ?Latheticocarcinus atlanticus, as well as two fragments belonging to the Majidae. This decapod fauna has species in common with correlative units of the Western Interior Seaway, the Gulf Coastal Plain, and the Atlantic Coastal Plain, supporting the hypothesis that the Mississippi Embayment is an ecotone for North American decapods.

Annotated synonymy of the recent freshwater mussel taxa of the families Margaritiferidae and Unionidae described from Florida and drainages contiguous with Alabama and Georgia
Authors: Williams James D. , Butler Robert S. , Wisniewski Jason M.
Published: February 2024

Freshwater habitats of the southeastern U.S. support a high diversity of mussels in the families Margaritiferidae and Unionidae, order Unionoida. River systems of Florida and drainages contiguous with Alabama and Georgia are known to be inhabited by 65 mussel species, representing about 20% of the North American fauna north of Mexico. This diversity led early naturalists to describe a large number of species which were based primarily on shell characters. There are 149 nominal taxa described from the study area, 72 (48%) in Florida, 68 (46%) in Georgia, and nine (6%) in Alabama. Most of the Florida taxa were descibed from the St. Johns River drainage. In Georgia, the majority of taxa were described from the Chattahoochee and Flint River drainages. Type localities were restricted herein for several taxa with vague specimen collection information reported in the original description. Of the 149 taxa described from the study area, it was determined that 41 (28%) are valid species. This represents 64% of the recognized mussel fauna that occur in the study area. The remaining 23 (35%) recognized species in the study area were described from outside drainages, and one (1%) species is undescribed. There are 40 described and one undescribed species endemic to the study area.
Dental History Transcends Professional Sports: The Tooth Protector in Early Professional Baseball
Authors: Mills Stephen C. , Croll Theodore P.
Published: February 2024

Protection of athletes during sporting activities was of some concern even in the late 1800s. That concern continues, over 140 years later. In baseball, safety for the catcher was of primary concern because of inherent risks of being “behind the plate” while balls are pitched, bats are swung, and runners attempting to score come barreling in. Doug Allison was the skilled catcher for the 1869 Cincinnati Red Stockings who was known to use certain objects for self-protection, including George Wright’s rubber “Mouthpiece.” This report reviews earliest development of mouth protection in baseball, as known through reports of the times, and Doug Allison’s career.

A gliricídia (Gliricidia sepium (Jacq) Kunth ex Walp) é uma leguminosa que vem sendo utilizada em sistemas agroflorestais, visando alimentação animal e contribuição na fertilidade do solo. Durante o seu cultivo é necessária a realização do manejo de plantas daninhas, pois essas podem interferir no crescimento e no desenvolvimento da gliricídia, sendo fundamental conhecer a habilidade competitiva da cultura com as plantas daninhas. Diante do exposto, este trabalho teve como objetivo avaliar a competitividade da gliricídia convivendo com as plantas daninhas Senna obtusifolia (fedegoso), Commelina benghalensis (trapoeraba), Bidens subalternans (picão-preto), Ipomoea triloba (corda-de-viola) e Urochloa brizantha (braquiária). O experimento foi montado em casa de vegetação, em delineamento inteiramente casualizado, com quatro repetições. Cada unidade experimental foi composta por um vaso contendo uma muda de gliricídia em convivência com três plantas daninhas de cada espécie, e o monocultivo das seis espécies, como padrão de comparação. Foi avaliado o crescimento inicial das mudas de gliricídia e das plantas daninhas através do diâmetro do caule, altura da planta e contagem do número de folhas; volume de raiz; massa da matéria seca das folhas, do caule e da raiz. Os dados foram submetidos à análise de variância (p<0,05) e quando significativas, as médias foram comparadas pelo teste de Tukey. A competição da gliricídia com as plantas daninhas resultou na redução de todas as variáveis analisadas. Os resultados obtidos comprovaram que todas as plantas daninhas, com exceção de C. benghalensis, interferiram negativamente no crescimento da espécie arbórea.

Introduction: The mechanisms of cell differentiation and pathogenesis in oral epidermoid cysts and dermoid cyst is poorly know. Objective: To report clinicopathological features and investigate cytokeratin profile of oral epidermoid cysts and dermoid cyst. Material and Methods: Eight cases of epidermoid cysts, 4 of dermoid cyst, and 2 Fordyce granules were included. For analysis of the immunohistochemical expression of cytokeratins (6, 7, 8, 10, 13, 14, 18 and 19), brown staining in the sections examined were defined as positive considering three layers: superficial, intermediate and basal. Results: In dermoid cyst, cytokeratins 7, 8, 9 and 19 were expressed in one case. Cytokeratin 6 was detected in six cases of epidermoid cysts. Cytokeratins 10, 13 and 14 were expressed in all cysts. Cytokeratin 18 was absent in all cysts. Cytokeratins 10 and 14 was observed in Fordyce granules. Cytokeratin 10 was more expressed in peripheral cells and immature sebaceous glands. As these glands became more differentiated, cytokeratin 10 was not detected, while cytokeratin 14 was expressed in mature sebocytes. Cytokeratins 10, 13 and 14 were expressed in the lining mucosa adjacent to Fordyce granules, similar to normal oral mucosal lining. Conclusion: cytokeratin profile is altered in dermoid cyst and epidermoid cysts compared to lining oral mucosa.

Oral squamous cell carcinoma (OSCC) is one of the most common cancers and presents the highest mortality rate of head and neck tumours. The aim of this study was to eva- luate the clinical and histological features of patients with OSCC in Florianópolis, Santa Catarina, Brazil between 2006 and 2016. Demographic and clinical characteristics such as age, gender, tobacco and alcohol consumption, anatomical site, clinical stage, and tre- atment were retrospectively collected from histopathological and medical reports. Of 196 patients with OSCC, 82.14% were male with a mean age of 58.28±10.45 years. Tobacco and alcohol consumption was reported in 88.76% and 75.9% of patients, respectively. The tongue was the anatomical site most affected (25.13%) and ulcers were the most prevalent clinical aspect (95.21%). A total of 103 (52.55%) patients were diagnosed with advanced stage (III/IV). Regarding treatment, 59.24% received more than one type of therapy, while 39.67% were treated exclusively with surgery. Regarding histological differentiation, 72.9% of the cases were moderately/poorly differentiated, 23.8% had vascular invasion, 17.9% had lymphatic invasion, and perineural invasion was observed in 29.5% of the patients. The survival rate showed a worse prognosis for patients diagnosed at stage III/ IV and the primary tumour was located in the inferior level of the mouth in 80% of these cases. The results showed that the majority of cases were diagnosed at an advanced stage, compromising treatment and prognosis. Educational and preventive measures should be improved in an effort to allow for early diagnosis.

Gorham Stout syndrome (SGS) is a rare disease that affects the bones causing idiopathic osteolysis. The prognosis of SGS is quite variable and impossible to predict, in most cases, bone destruction progresses from months to years, the affected area does not regenerate or repair itself. The etiology of the disease is unknown. The aim of the present study is to report a case in female patient showing a lesion in the left jaw compatible with the SGS. A 45-year-old female patient, was referred to the CTBMF team. After performing imaging tests to perform the differential diagnosis, they suggested as differential diagnosis of maxillary ossifying fibroma lesion and fibrous dysplasia, in relation to femoral lesion, was suggestive and enchondroma. The proposed treatment was surgical removal with curettage of the lesion in the femur and maxilla. With the result of the histopathological examination, the diagnosis of SGS was concluded. During the postoperative follow-up period, the lesion showed no signs of relapse, guaranteeing success in the treatment.

Published: February 2024

Introduction: The use of complete removable dentures is associated with a high frequency of oral mucosal lesions. Among them, denture-induced fibrous inflammatory hyperplasia is one of the most common. Interestingly, some oral lesions occurring beneath complete dentures can present exuberant new bone formation, creating diagnostic difficulties. Patients: We present two interesting cases affecting complete denture wearers, showing each one unusual bone-forming lesion. The first was diagnosed as extensive mature bone formation with osteochondromatous metaplasia foci and the second as an exuberant exostosis. Discussion: Oral soft tissue lesions caused by ill-fitting dentures may present distinct microscopic variations such as osseous and chondromatous metaplasia arising of the connective tissue. These cases evidence that contributing factors for exostosis may be the chronic oral mucosa irritation at the tissue/denture base interface and a response to stresses transferred to the alveolar bone by the ill-fitting denture. Conclusion: Awareness of these lesions is essential to avoid unnecessary procedures, prevent misdiagnosis, reduce patient anxiety, consequently influencing oral health related-quality of life of edentulous patients.

Published: February 2024

Solitary keratoacanthoma (S-KA) is a benign epithelial proliferation that affects the sun-exposed skin of elderly. It presents rapid growth often followed by spontaneous remission. S-KA clinical and microscopic features are very similar to the squamous cell carcinoma’s (SCC) and differentiating them can be a challenge. S-KA involving the lip is rare and frequently is managed as SCC, leading to overtreatment. Despite of few investigations aiming at differentiate S-KA and SCC are available, there is no compilation of case reports of lip S-KA. Thus, our aim was to conduct a comprehensive review of the literature and report a case of lip S-KA. The review was conducted until 2016 and only 21 cases were found. Lip S-KA was more common in elder man, lower lip, and most of them were asymptomatic. The lesions measured 16.7mm on average with duration of approximately 12 weeks. The most performed treatment was excisional biopsy of lesion despite of the self-healing potential of the lesion.

Introduction: Aloe vera is a herbal plant that has been used widely for centuries as a natural medicine. Its therapeutic activity is based on the numerous beneficial pharma- cological properties induced by the parenchyma. It is easy to access, manipulate and is low-cost; these properties have led to a progressive increase in its consumption. However, its action in the cicatricial process is not fully known, which has driven research into new discoveries in this context. Aim: The purpose of this literature narrative review was to discuss the current information available on the benefits of using Aloe vera in the wound healing process. Materials and methods: Scientific articles were selected from the Pub- Med and LILACS databases between February 2018 and July 2018, by using the English and Portuguese words of “Aloe Vera”, “Wound healing”, “Healing” and “Tissue repair”. In total, 229 articles were found in PubMed and 63 articles were found in LILACS. After reading the abstracts, 30 articles that reported how the pharmacological properties of Aloe vera influence the healing process were selected. Results: Aloe vera exerted positive effects on the treatment of oral ulcers and protection of the mucous membranes, with reductions in these lesions and the painful symptomatology. In addition, it was effective for the prevention and treatment of oral mucositis and the reduction of candidiasis in patients with cancer. Promising results have also been reported from the treatment of symptomatic oral lichen planus. In the treatment of plaque-induced gingivitis, Aloe vera provided a significant improvement in inflammation. Final considerations: The literature supports the anti-inflammatory and cicatricial potential of Aloe vera, which has a wide indication for the treatment of several conditions. Therefore, additional clinical studies based on scientific evidence are needed to gain a better understanding of Aloe vera, its compounds and therapeutic indications.

Oral squamous cell carcinoma (OSCC) is one of the most common cancers and presents the highest mortality rate of head and neck tumours. The aim of this study was to eva- luate the clinical and histological features of patients with OSCC in Florianópolis, Santa Catarina, Brazil between 2006 and 2016. Demographic and clinical characteristics such as age, gender, tobacco and alcohol consumption, anatomical site, clinical stage, and tre- atment were retrospectively collected from histopathological and medical reports. Of 196 patients with OSCC, 82.14% were male with a mean age of 58.28±10.45 years. Tobacco and alcohol consumption was reported in 88.76% and 75.9% of patients, respectively. The tongue was the anatomical site most affected (25.13%) and ulcers were the most prevalent clinical aspect (95.21%). A total of 103 (52.55%) patients were diagnosed with advanced stage (III/IV). Regarding treatment, 59.24% received more than one type of therapy, while 39.67% were treated exclusively with surgery. Regarding histological differentiation, 72.9% of the cases were moderately/poorly differentiated, 23.8% had vascular invasion, 17.9% had lymphatic invasion, and perineural invasion was observed in 29.5% of the patients. The survival rate showed a worse prognosis for patients diagnosed at stage III/ IV and the primary tumour was located in the inferior level of the mouth in 80% of these cases. The results showed that the majority of cases were diagnosed at an advanced stage, compromising treatment and prognosis. Educational and preventive measures should be improved in an effort to allow for early diagnosis.

Mucosa-associated lymphatic tissue (MALT) lymphomas commonly occur in the stomach however, rare cases of MALT lymphomas involve the minor salivary gland. We did a literature review and described the fourth case in the English literature of adults affected by a MALT lymphoma in the lip. A 68-year-old woman with probable primary Sjögren’s syndrome (SS) was referred to our dentistry and stomatology service, complaining that her lower lip had progressively thickened during the past 4 years. An incisional biopsy was performed, and the microscopic examination showed a dense, diffuse lymphoplasmacytic infiltration of the salivary glands, with plasmacytic differentiation. The immunohisto- chemical analysis revealed diffuse positivity of the neoplastic cells for CD20 and BCL-2; the plasma cells were positive for CD138 and Lambda, which was consistent with MALT lymphoma. SS and Immunoglobulin G4-related disease were excluded. The total regression of the lesion was obtained after treatment with surgery, chemotherapy, and radiotherapy.

Introduction: the hemangioma is a vascular lesion of uncertain etiology. It is most fre- quently observed in the head and neck region (50% of the cases). In the oral cavity, com- monly affect the lower lip, tongue, jugal mucosa and palate. There are several therapeutic modalities to treat hemangiomas, among them; sclerotherapy stands out, since it represents a simple, comfortable, effective and low-cost method of treatment. Objective: compare the treatment between two sclerosing agents: the ethanolamine oleate 5% and glucose solution 50%. Side effects and period of treatment was also analyzed and illustrated with three clinical cases. Material and methods: three cases presenting diascopy blanching lesions, and vascular injury, were aspirated being collected bloody content, confirming the diagnosis of vascular injury, and establishing a clinical diagnosis of hemangioma. Infiltration anesthesia was applied at a distance, and slow implementation of sclerosing agents was injected, intralesionally. An interval of seven days between each application was maintained. Patients were asked about possible occurrence of side effects: burning, pain, swelling the region. Results: both sclerosing agents used in this study are efficient, easy to perform, with market availability and reduced cost. Conclusion: regarding the duration of the treatment, no significant difference between the sclerosing agents was observed, because both needed a few applications for the complete resolution of the lesions, no recurrence was observed and early side effects were pain, swelling, redness and burning.

Introduction: Fissured tongue is a common malformation characterized by deep grooves or fissures in the dorsum of the tongue. Fissured tongue is considered to be a variant of normal tongue architecture and is a totally benign condition. Objective: The aim of this present study is to examine the prevalence of fissured tongue, the most commonly occurring type of fissure and the association between the occurrence of fissured tongue with age, gender and, systemic conditions among the Kerala population who visited the dental OP in Pushpagiri College of Dental Sciences, Thiruvalla. Material and methods: A total of 500 patients consisting of 250 males and 250 females between the ages of 0-80 years were included in the study. The patients were divided into 4 age groups as 0-20 years, 20-40 years, 41-60 years and 61-80 years. The tongue was examined for the presence or absence of fissures, type of fissures and associated symptoms. The obtained data was subjected to statistical analysis using T test and ANOVA test with p value < 0.05 as statistically significant. Results: From a sample of 500, a total of 143 patients (prevalence rate of 28.6%) were found to have fissured tongue. The prevalence of fissured tongue was found to be significantly higher among males and was found to be more prevalent in the age group ranging from 41-60 years. A total of 103 patients had median fissures, 25 had lateral fissures and 30 had a combination of median and lateral fissures. Diabetes and hypertension were the most commonly observed systemic illness. Conclusion: Dentists and other oral health care workers need to be aware of the prevalence and management of patients with fissured tongue. As it’s a benign condition, fissured tongue requires no specific treatment.

Introduction: The Wnt signaling pathway is directly related to the development process of odontogenic keratocysts (OKC) and ameloblastomas (AM). However, the molecular mechanisms involved in the genesis and the activation process of the Wnt pathway of these tumors still need to be elucidated. Objective: To evaluate the immunohistoche- mical expression of Wingless-type (Wnt) proteins in OKC and AM. Materials and methods: Immunohistochemical staining was performed using antibodies against Wnt1, Wnt5a, SUFU and β-catenin proteins in cases of odontogenic keratocysts (n = 11) and ameloblastomas (n = 13). The analysis was performed by analysing staining intensity in both epithelial cells and fibroblasts. Results: Epithelial cells exhibited predominance of immunostaining in both lesions, with statistical association for SUFU markers in AM (p = 0.05) and β-catenin in OKC (p = 0.04). Wnt1 and Wnt5a had 100% immunostaining in epithelial cells and fibroblasts of AM and OKC, respectively. SUFU was significantly higher in OKC epithelial cells when compared to those in AM (p = 0.05). There was no statistical association in the immunosuppression of fibroblasts between AM and OKC, for all markers. Conclusion: The high intensity immunoexpression of Wnt1, β-catenin, SUFU and Wnt5a markers in OKC and AM epithelial cells suggests that Wnt signaling pathways, canonical and non-canonical, are activated and may contribute to the develop- ment, progression and aggressiveness of these lesions. On the other hand, it is suggested that the significant presence of SUFU in OKC epithelial cells confers a protective factor to this lesion, when compared to AM epithelial cells, indicating that the inactivation me- chanisms of the canonical pathway may be functioning. However, further investigations should be conducted to confirm such hypotheses.

The pursuit of perfection makes younger people undergo aesthetic procedures without formal indication. However, young patients may be susceptible to a disease such as head and neck cancer which treatment can compromise the adhesion of these indirect mate- rials. Here, we present an analyze, of the gamma radiation effects on crystallographic morphology of human dental enamel after laminate veneer debonding with Er,Cr:YSGG laser. Thus, human dental enamel samples were prepared and randomized into 2 groups (n=10): Laser Irradiation (L) and Gamma + Laser Irradiation (GL) group. Scanning elec- tron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were performed before bonding and after debonding using Er,Cr:YSGG. Only Gamma + Laser Irradia- tion group received a cumulative dose of 70 Gy gamma radiation used in head and neck cancer radiotherapy. SEM images showed that both GL and L groups presented altered morphology. EDS showed an decrease in Ca and P intensities after laser debonding of laminates veneers in both group. Therefore, a proper laser facet removal protocol should be established for healthy patients and patients who have been exposed to radiotherapy for head and neck cancer.

Objective: The present study evaluated the expression and activation of the STAT-3 in potentially malignant disorders and its association with dysplasia grade. Methods: Twenty-four fragments from two distinct areas, namely the buccal mucosa and the tongue, with 10 cases of hyperkeratosis without dysplasia and 14 cases of hyperkeratosis with mild, moderate or severe dysplasia, were analyzed. Immunohistochemistry for STAT-3 and P-STAT-3 was performed using the biotin-streptavidin-peroxidase method. Results: In both hyperkeratosis with and without dysplasia STAT-3 demonstrated cytoplasmic ex- pression in epithelial layers. Nuclear expression in hyperkeratosis with mild or moderate dysplasia was seen. In hyperkeratosis with severe dysplasia the lower epithelial layers there were areas exhibiting loss of labeling. P-STAT-3 showed nuclear expression in all epithelial layers, except for the superficial layer, in hyperkeratosis without dysplasia. In hyperkeratosis with mild and moderate dysplasia, nuclear expression was seen in all epithelial layers, except for the superficial layer, with a few cells showing no expression. Conclusion: Regarding hyperkeratosis with severe dysplasia, there was loss of expression in a higher number of cells. In both hyperkeratosis with and without dysplasia, STAT-3 activation was found to be abnormal and no significant difference for STAT-3 expression at different dysplasia grades was observed.
