Published: August 2022

Abstract. Groundwater can respond quickly to precipitation and is the main contribution to streamflow in most catchments in humid, temperate climates. To better understand shallow groundwater dynamics in a boreal headwater catchment, we installed a network of groundwater wells in two areas in the Krycklan catchment in Northern Sweden: a small headwater catchment (3.5 ha, 54 wells) and a hillslope (1 ha, 21 wells). The average wells depth was 274 cm (range: 70–581 cm) and recorded the groundwater level variation at a 10–30 min interval between 18. July 2018–1. November 2020. Manual water level measurements (0–26 per well) during the summer seasons in 2018 and 2019 were used to confirm and re-calibrate the water level logger results. The groundwater level data for each well was carefully processed and quality controlled, using six data labels. The absolute and relative positions of the wells were measured with a high-precision GPS and terrestrial laser scanner (TLS) to determine differences in groundwater levels and thus groundwater gradients. During the summer of 2019, all wells with sufficient water were sampled and analyzed for electrical conductivity, pH, absorbance, anion and cation concentrations, as well as δ18O and δ2H. This combined hydrometric and hydrochemical dataset can be useful to test models that simulate groundwater dynamics and to evaluate subsurface hydrological connectivity. We therefore made the data available on https://www.safedeposit.se/projects/82 (Erdbrügger et al., 2022).

Abstract. Given the good persistence of sea surface temperature (SST) due to the slow-varying nature of the ocean, an atmospheric model coupled with a Slab Ocean Model (SOM) instead of a 3-D dynamical ocean model is designed as an efficient approach for extended-range predictions. The prediction experiments from July to December 2020 are performed based on the Weather Research and Forecasting (WRF) model coupled to the SOM (WRF-SOM) with the initial and boundary conditions same as the WRF coupled to the Regional Ocean Model System (WRF-ROMS). The WRF-SOM is verified to have better performance of SSTs in the extended-range predictions than WRF-ROMS since it avoids the complicated model biases from the ocean dynamics and seabed topography when extended-range predictions are made using a 3-D dynamical ocean model. The improvement of SSTs can lead to the remarkable impact on the response of the atmosphere from the surface to the upper layer. Taking typhoon as an example of extreme events, the WRF-SOM can obtain comparable intensity predictions and slightly improved track predictions due to the improved SSTs in the initialized WRF-SOM system. Overall, the WRF-SOM can ensure the stability of extended-range prediction and reduce the demand for computing resources by roughly 50 %.

Published: August 2022

Abstract. The effect of deep convection parameterisation on the jet stream above the cold front of an explosive extratropical cyclone is investigated in the global numerical weather prediction model ARPEGE, operational at Météo-France. Two hindcast simulations differing only in the deep convection scheme used are systematically compared with each other, with (re)analysis datasets and with NAWDEX airborne observations. The deep convection representation has an important effect on the vertical structure of the jet stream above the cold front at 1-d lead time. The simulation with the less active scheme shows a deeper jet stream, associated with a stronger potential vorticity (PV) gradient in the middle troposphere. This is due to a larger deepening of the dynamical tropopause on the cold air side of the jet and a higher PV destruction on the warm air side, near 600 hPa. To better understand the origin of this stronger PV gradient, Lagrangian backward trajectories are computed. On the cold air side of the jet, numerous trajectories undergo a rapid ascent from the boundary layer to the mid-levels in the simulation with the less active deep convection scheme, whereas they stay at mid-levels in the other simulation. This ascent explains the higher PV noted on that side of the jet in the simulation with the less active deep convection scheme. These ascending air masses form mid-level ice clouds that are not observed in the microphysical retrievals from airborne radar-lidar measurements. On the warm air side of the jet, in the warm conveyor belt ascending region, the Lagrangian trajectories with the less active deep convection scheme undergo a higher PV destruction due to a stronger heating occurring in the lower and middle troposphere. In contrast, in the simulation with the most active deep convection scheme, both the heating and PV destruction extend further up into the upper troposphere.

Published: August 2022

Bamboo internodes can serve as a breeding ground for a diverse mosquito fauna, some with relative epidemiological importance. The goal of this study is to determine the mosquitoes´ species found in the bamboo internodes at the northwestern region of Rio Grande do Sul, Brazil. From September 2016 to August, 2017 immature forms of mosquitoes were collected from bamboos (Bambusa sp.), in the quarterly intervals (ten plants per collection) through 0.5 cm in diameter perforations on 40 internodes sides. After 30 days, the perforated internodes were cut out and their contents were taken to the laboratory where the immature forms of mosquitoes developed to adult stage were identified. A total of 367 immature forms of Culicidae were collected, however only 158 (43.1%) have developed to adult stage and were identified at a specific level. Eight species were identified: Onirium personatum (Lutz, 1904), Sabethes aurescens (Lutz, 1905), Sa. intermedius (Lutz, 1904), Sa. purpureus (Theobald, 1907), Shannoniana fluviatilis (Theobald, 1903), Trichoprosopon pallidiventer (Lutz, 1905), Wyeomyia limai (Lane & Cerqueira, 1942) and Wyeomyia serratoria (Dyar & Nuñez Tovar, 1927). Thus, the study showed the importance of this type of breeding in order to maintain the mosquito fauna in the wild areas in the studied region. The finding of the species On. personatum and Sh. fluviatilis was also reported for the first time in the State.

This study aims to determine the prevalence of Fasciola hepatica in cattle from the Abancay, Curahuasi, and Tamburco districts in the Abancay province, Apurímac, Peru, during the 2018 rainy season, and the association between prevalence and age, breed, and district of origin. In total, 295 stool samples were collected, namely 34 from Tamburco, 193 from Curahuasi and 68 from Abancay. For coproparasitological evaluation, the four-sieve sedimentation technique described by Girão and Ueno was used. The total prevalence of F. hepatica in the cattle sampled in this study was 50.8% (150/295), and the prevalence by district was 42.6% (29/68) in Abancay, 53.8% (104/193) in Curahuasi, and 50% (17/34) in Tamburco. No significant association was found with the variable district of origin (p<0.05). However, using a bivariate logistic regression analysis, a significant association was found between F. hepatica prevalence and the breed variable (p=0.008). A similar significant association with the breed variable (p=0.007) was also found using a multiple logistic regression analysis. The high prevalence of F. hepatica identified in this study is consistent with previous reports made in the Apurímac Region, an area considered hyperendemic for the parasite, thus highlighting the need for effective health programs to control disease distribution, which may have an economic and, because of its zoonotic character, public health impact.

Boosting photocatalytic Suzuki coupling reaction over Pd nanoparticles by regulating Pd/MOF interfacial electron transfer
Authors: Sun Zi-Xuan , Jiang Hai-Long ,   Department of Chemistry, University of Science and Technology of China, Hefei 230026, China
Published: August 2022

Palladium-catalyzed C-C coupling reactions are of significant importance, but they often require harsh conditions. Herein, we report an interface-regulated photocatalytic Suzuki coupling reaction over Pd nanoparticles supported on a metal-organic framework (MOF), ZIF-8. Two Pd/MOFs were synthesized, PdPVP/ZIF-8 and Pd/ZIF-8, which have similar Pd sizes and loading amounts, except that the former contains poly(vinylpyrrolidone) (PVP) as a surfactant. The diffuse-reflectance infrared Fourier transform of CO adsorption (CO-DRIFT) indicates that Pd/ZIF-8 represents a more negative electronic state of Pd than PdPVP/ZIF-8. In the photocatalytic Suzuki coupling reaction between iodobenzene and phenylboronic acid, Pd/ZIF-8 exhibits excellent performance (99.1% yield), much better than that of PdPVP/ZIF-8 (57.9% yield). Moreover, Pd/ZIF-8 is highly stable and shows broad substrate scope for this reaction. The superior activity of Pd/ZIF-8 can be attributed to sufficient electron transfer between the MOFs and Pd nanoparticles in the absence of an interfacial surfactant. This work provides new insights into a Pd-catalyzed C-C coupling reaction involving photocatalysis and interfacial electron transfer.

REMOÇÃO DE TERCEIRO MOLAR SUPERIOR DESLOCADO PARA O INTERIOR DO SEIO MAXILAR: RELATO DE CASO
Authors: De Albuquerque José Reinan Custódio , Gomes Junior George Matos Ferreira , Santos Daniel Facó da Silveira , Cavalcante Rebeca Pereira , Maia Lucas Alexandre
Published: August 2022

INTRODUÇÃO: A remoção cirúrgica dos terceiros molares impactados é um dos procedimentos que fazem parte da rotina clínica dos cirurgiões bucomaxilofaciais. Comumente, estão relacionados a possíveis complicações como as lesões em nervos e o deslocamento de dentes para dentro de espaços adjacentes. A presença de corpos estranhos nos seios paranasais é considerada rara pela literatura, sendo o seio maxilar normalmente o mais acometido. Diversos fatores estão relacionados com a ocorrência desses tipos de agravos, no entanto, sua etiologia está diretamente relacionada com a íntima relação dos terceiros molares às estruturas nobres e a inexperiência do cirurgião, contribuindo para a incidência dos casos. O presente trabalho busca relatar um caso clínico de tratamento de uma complicação cirúrgica de um terceiro molar deslocado para o interior do seio maxilar. MÉTODO: Paciente M.P.M, 40 anos, sexo feminino compareceu ao ambulatório de Cirurgia e Traumatologia Buco-Maxilo-Facial do Hospital Geral de Fortaleza (HGF, Fortaleza, Ceará, Brasil) com dor, eritema e aumento de volume em hemiface direita. Na anamnese foi relatado da tentativa de exodontia do dente 18, onde o dente foi deslocado para o interior do seio maxilar direito. Após exame clínico, somado à observância de cortes tomográficos, constatou-se a presença do elemento 18 no interior do seio maxilar direito, sendo assim programada a remoção do mesmo. DISCUSSÃO E CONCLUSÃO: Para avaliar a relação entre o seio maxilar e os terceiros molares superiores a radiografia panorâmica e a Tomografia Computadorizada de Feixe Cônico (TCFC) são essenciais na tomada de decisão cirúrgica e planejamento preciso do caso, tendo a técnica de Calldwel-Luc  possibilitando poucas complicações e permitindo um amplo acesso. O deslocamento de dentes para dentro do seio maxilar compõe parte das complicações de exodontias de elementos dentários superiores, portanto, o cirurgião buco-maxilo-facial deve estar apto a diagnosticar e tratá-la adequadamente.
RELAÇÃO ENTRE PERIODONTITE E OSTEONECROSE MANDIBULAR ASSOCIADA A MEDICAMENTOS: UMA REVISÃO DE LITERATURA
Authors: Albuquerque Iago Gomes , Pereira Eva Naira Aragão , De Farias Ana Waléria Martins , Pinto Régila Maria Farias , Nunes Nara Lhays Teixeira
Published: August 2022

INTRODUÇÃO: A periodontite é caracterizada como doença inflamatória desencadeada pelo acúmulo de biofilme supra e subgengival, levando a destruição óssea e do ligamento periodontal. Osteonecrose mandibular (ONJ) é uma patologia na qual é definida como área de osso exposto na região maxilofacial, ou região óssea que possa ser sondado através de fístula intraoral ou extraoral, por mais de oito semanas, sem históricos de radioterapia ou metástases, que fazem uso de potentes antirreabsortivos. Portanto, objetiva-se avaliar a relação entre periodontite e osteonecrose mandibular associada a medicamentos. MÉTODOS: Um levantamento bibliográfico foi realizado de 2017 a 2022 nas bases de dados Pubmed e Web of Science, utilizando-se os descritores “Gingivitis”, “Periodontal disease”, “Periodontitis” e “Osteonecrosis of the jaw”, utilizando os operadores booleanos OR e AND. Obteve-se um total de 155 e 122 artigos, respectivamente. Após análise rigorosa dos títulos e resumos, foram selecionados 10 artigos (8 do Pubmed e 2 do Web of Science) seguindo os critérios elegíveis. RESULTADOS E DISCUSSÃO: Um estudo em ratos com periodontite tratados com ácido zoledrônico tiveram redução significativa na prevalência de ONJ ao tratamento periodontal prévio. Em um estudo clínico esse fármaco mostrou-se eficaz na prevenção de periodontite em pacientes com boa higiene oral. No entanto, um caso clínico demonstrou ONJ após terapia periodontal não cirúrgica. Estudos em camundongos, apresentaram ocorrência de ONJ, combinado a zolendronato, sem extrações dentárias. Em contrapartida, outro estudo evidenciou que condições inflamatórias pré-existentes, associadas a exodontias, desempenham papel importante no desenvolvimento de ONJ associada a drogas. Ainda foi relatado que zolendronato inibe a reabsorção óssea periodontal, mas não interfere na reação inflamatória. CONCLUSÃO: Em suma, os estudos demonstram que o processo inflamatório da periodontite pode influenciar no desenvolvimento de ONJ, assim como, as drogas antirrebsortivas, como o aledronato, podem influenciar beneficamente na periodontite, no entanto, o tratamento periodontal prévio é indispensável.

Published: August 2022

A COVID-19 passou a ser considerada um desafio urgente à saúde devido à facilidade de transmissão do seu vírus causador (SARS-CoV-2), tornando-se rapidamente uma pandemia, com um número acelerado de novos casos e milhares de óbitos registrados. As investigações acerca das possíveis correlações da ação patogênica do SARS-CoV-2 com a cavidade oral são recentes, merecendo especial atenção das ciências odontológicas. Logo, o objetivo desta revisão é fazer uma análise da literatura existente que possua evidências científicas sobre as principais manifestações orais em pacientes acometidos com COVID-19 e quais, dentre elas, possam surgir no curso da infecção. Foi realizada uma revisão da literatura por meio de revistas científicas eletrônicas, livros da área odontológica e artigos científicos indexados nos portais eletrônicos da Biblioteca Virtual em Saúde (BVS) e PubMed, compreendidos entre os anos de 2020 e 2022. O presente estudo demonstra que o SARS-CoV2 tem receptores específicos com os quais se liga à cavidade oral e que quadros leves ou moderados de alterações de paladar são manifestações mais comumente relatadas, além de lesões fúngicas e virais em mucosa oral. Dentre tais lesões, as lesões erosivas ou ulcerativas se apresentam clinicamente com sintomatologia dolorosa intensa, portando bordas irregulares, sendo geralmente encontradas na língua, mucosa labial e palato. Porém, por ser uma patologia relativamente nova na literatura médica e odontológica, estudos clínicos são necessários para investigar se a infecção pelo coronavírus é o fator primordial para o surgimento das lesões ulceradas ou se a deficiência do sistema imune e as condições de higiene bucal do paciente são preponderantes na patogênese de tais lesões. No contexto da pandemia do COVID-19, vale ressaltar a importância da atuação do cirurgião-dentista para o diagnóstico e tratamento das possíveis alterações orais, elevando a qualidade de vida dos pacientes.

Published: August 2022

Introdução: Nos tratamentos odontológicos deve-se buscar o equilíbrio entre a estética “branca” e “vermelha”. Em casos de coroas clínicas curtas, uma interação com um periodontista pode ser necessária para corrigir anormalidades na simetria e contorno dos dentes por procedimentos cirúrgicos. A cirurgia de ostectomia pode ser necessária para fornecer quantidades suficientes de estrutura dentária para a preparação e restauração ideais do dente. Os avanços nos materiais odontológicos tornaram disponíveis para a odontologia restaurações fabricadas em CAD/CAM, esta abordagem suporta um fluxo de trabalho intraoperatório para a restauração, fabricação e inserção de implantes dentários em uma única visita usando blocos cerâmicos pré-fabricados. Diante disso, o objetivo do presente trabalho é ressaltar a importância do conhecimento sobre a estética branca e vermelha para um planejamento multidisciplinar, envolvendo a cirurgia plástica periodontal e o trabalho restaurador com laminados cerâmicos para um resultado estético. Métodos: O estudo é caracterizado como uma revisão de literatura, foi realizada pesquisa por artigos nas Bibliotecas Virtuais PubMed e Ebsco, obtendo um resultado de 37 artigos. Os critérios de inclusão foram produções bibliográficas nos idiomas português e inglês, sendo publicados nos últimos 5 anos. Os critérios de exclusão foram as produções que se enquadravam como dissertações e monografias. Resultados/Discussão: Foram selecionados 7 artigos relacionados com o tema. O papel do cirurgião-dentista é compreender e levar em consideração os dentes, os tecidos moles e as características faciais do paciente, e estabelecer uma harmonia entre os dentes e o periodonto. Conclusão: Diante disso, foi possível compreender que é imprescindível o conhecimento dos aspectos que tornam um sorriso harmônico, para que se alcance um equilíbrio entre a estética vermelha e branca, e a cirurgia de aumento de coroa clínica e a técnica de restaurações fabricadas em CAD/CAM podem ser grandes aliadas para alcançar esse resultado.

Published: August 2022

INTRODUÇÃO: As recessões gengivais constituem um dos principais problemas periodontais prevalentes na população. O enxerto de tecido conjuntivo autógeno, ainda é considerado padrão ouro para o seu tratamento, sendo a primeira escolha para melhorar os desfechos clínicos. Entretanto, materiais alternativos, de natureza alógena, especialmente de enxerto de tecido mole foram introduzidos, e, mostram resultados favoráveis no que se refere ao tratamento das recessões gengivais. MÉTODOS: Neste sentido, realizou-se uma pesquisa descritiva, documental, de artigos científicos na base de dados PUBMED, utilizando os termos de acordo com Descritores em Ciência da Saúde: “allografts”, “gingival recession”, e, “periodontics”, em que se utilizou o caractere booleano “and”. RESULTADOS E DISCUSSÕES: Compõem este estudo uma revisão sistemática e uma meta-análise, somando 72 estudos randomizados, com pacientes acompanhados por até 18 meses. Mais de 200 pacientes e 300 defeitos foram envolvidos. Derivados plaquetários, isolados, associados a enxerto de tecido conjuntivo e/ou osso liofilizado foram utilizados para regeneração periodontal, e o consequente recobrimento de recessões gengivais. Coberturas de recessões gengivais Classes I e II de Miller foram analisadas em outros 70 pacientes. O enxerto de tecido conjuntivo isolado foi comparado a este, associado ou não a matriz dérmica, aloenxerto de fáscia de lata e biomembranas, bem como em retalhos reposicionados coronalmente. CONCLUSÕES: Com base na literatura consultada foi possível inferir que a utilização de aloenxertos em reconstruções periodontais, especialmente no tratamento das recessões gengivais, é certamente viável, previsível, e desfruta deste modo de inúmeras opções de tratamentos diretos e associações, desde a utilização de biomembranas e osso liofilizado, matriz dérmica acelular, agregados e derivados plaquetários; estes últimos, necessitando ainda de pesquisas mais robustas, com maiores amostras e tempos de acompanhamento.

Authors:   Form of Public Safety and Culture, Shin Jeong Soon , Kim Dong Won
Published: August 2022

This study is a qualitative study using a phenomenological approach to understand what high school seniors experience through one-on-one in-depth interviews and the meaning structure of the experience to provide a comprehensive and holistic understanding for students who need to choose and decide a new career in the era of infectious diseases. Participants in this study were first graders in high school when COVID-19 swept the world in 2019 and students who took the entrance exam in 2022. In selecting study participants, purposeful sampling and snowball sampling were used to find participants who could provide the timelyness of the sample, various experiences, and deep insight. Participants in the study were 8 people who provided voluntary consent in advance, and data collection was conducted from January to March 2022. The results of individual in-depth interviews were analyzed by applying Giorgi's phenomenological research method, As a result of the analysis, the experiences of high school seniors were derived into five categories and 15 subcategories, including "confusing", "depression", "difficulty learning on their own", "change of entrance exams" and "adaptation". Through this study, the experience of high school seniors attending high school during the COVID-19 period stated that unstable and confused high school students in our society are more required to actively cope with and support learning, career, and emotional support. Therefore, it is necessary to have a comprehensive understanding of the experiences of high school seniors during the COVID-19 period, and to accurately identify their needs and provide necessary interventions so that they can start as successful career paths and healthy members of society. In addition, it suggests a deep exploration of the role of educational governance in the era of infectious diseases.

Aims: Laparoscopic cholecystectomy (LC) is currently the standard treatment for symptomatic gallstones. In the presence of moderate to severe inflammation when dissection of the cholecystohepatic triangle cannot be safely achieved, laparoscopic partial cholecystectomy (LPC) has been proposed as an alternative to open conversion to prevent bile duct injuries. The aim of this study is to review our experience of the technique.
Materials and Methods: A retrospective review of all patients who underwent laparoscopic cholecystectomy under the upper gastrointestinal surgical unit at Westmead Hospital was undertaken. The study included all emergency and elective cases during a period from February 2012 to February 2014. Demographic, clinical, operative and postoperative characteristics including operative technique, placement of a drain, complications, length of hospital stay and histopathology were collected.
Results: A total of 404 patients underwent LC during the two year study period of which 23 were LPC's. Patients who underwent LPC tended to be older and more likely of the male gender. These patients were also more likely to be an emergency operation and have a higher ASA grade compared to the LC group. Length of stay and operative time tended to be longer. There were five (22%) bile leaks postoperatively and all were successfully managed with postoperative ERCP and stenting. The major complication rate was 35% (8/23) with no bile duct injury or perioperative mortality.
Conclusion: This current case series adds further evidence to suggest that LPC is a viable alternative to conversion in cases of difficult LC.

Background: Hand function is an important aspect of most of the activities of daily living. There are many conditions that cause direct impact on hand function but few of musculoskeletal conations indirectly influence the hand function but often ignored in rehabilitation. Objective: The aims of this study were to analyse the hand function among lateral epicondylitis (LE) patients and identify the influence of various parameters (Age, dominance, pain, range of motion (ROM), and chronicity) that may influence the hand function. Methods: Eighty six LE patients participated in this cross sectional study. The hand function was assessed using Perdue peg board along with various other parameters like age, dominance, pain, range of motion, and chronicity. Results: There was a significant difference between the hand function of affected and unaffected extremity (p<0.001, effect size of 0.425). Pain severity, chronicity of LE and wrist extension was strongly related to hand function with R value of -0.910, -0.788 and 0.698 respectively. Conclusions: The results highlight the possible hand function compromise among patients with LE. Out of all the assessed parameters pain severity, wrist extension ROM and chronicity of condition were associated with hand function compromise.

Background: Hypersensitivity pneumonitis (HP) refers to the inflammatory lung condition that results from inhalation of various (mostly organic) antigens leading to development of lymphocytic alveolitis and granulomatous pneumonitis. Pathogenesis of the disease is not fully understood and identification and removal of the causative agents remains the cornerstone of treatment and a major determinant of prognosis. Bronchoscopy and BAL can be used to characterize alveolitis and inflammatory cells infiltrate assuming to have a main role inthe pathogenesis of the disease process. Aim : to improve the characterization of alveolitis in HP on a number of patients with well-defined stages of disease activity and to assess the frequency of cellularity, CD4 and CD8 alveolitis. Subjects and methods: 88 HP cases diagnosed by thorough history, clinical examination, HRCT (with scoring system for each radiological pattern), spi rometry, and FOB with BAL for cellularity and flowcytometry (FCM) to determine CD4/CD8 ratio.Results: The mean total cell count (TCC)/cmm was (397±241) in subacute cases and (247±291) in chronic cases with statistically significant difference P-value 0.002. Mean lymphocytes percent was (45±19%) in subacute cases and 39±20% in chronic cases with no statistically significant value.

Introduction: Knee osteoarthritis (OA) is the most prevalent OA worldwide, particularly in the USA. Studies show that knee OA leads to functional limitations, including problems with weight tolerance during walking, climbing stairs, household activities, and lightweight package transport. Since the quadriceps muscles play a critical role in weight tolerance throughout the knee joint, weakness in these muscles diminishes the capacity to protect the knee and results in knee susceptibility to more physical stress and developed structural injuries. Abnormal quadriceps muscle functioning that often manifests into weakness is part of a movement disorder presumably due to certain neurological conditions such as Parkinson's disease (PD), stroke, etc., or knee injuries after surgery, arthritis, traumatic injuries, and more. This weakness can originate from atrophy or neural inhibition that prevents maximal activation of the quadriceps muscle. This condition is called arthrogenic muscle inhibition (AMI), which Hopkins first introduced in 1990. AMI is associated with several causes, including swelling, inflammation, pain, joint stiffness, and structural damage, though the importance of these causes remains unclear. Consistently, this phenomenon is caused by discharging the sensory receptors in the damaged knee joint.

Published: August 2022

The need for ideal restorative material in terms of enhanced clinical performance and longevity is a primary requirement, and concern, in contemporary restorative practice. None of the available restorative materials provide with biomechanical properties similar to that of natural enamel and dentin. Therefore the concept of replacing missing or defective tooth structures with natural enamel or dentin termed as “Biological Restorations” has resurfaced. The current review provides an insight into clinical applications with evidence of success, advantages, limitations, ethical and biosecurity risk concerns regarding biological restorations and also makes an attempt to propose a definition and a classification system based on clinical implications.

The purpose of the research is to figure out how to produce Lamivudine Film in a way that makes them taste; less unpleasant and dissolve quickly in the mouth. According to the results of Carr's index and Hausner's ratio, the flow properties of both model medications are quite subpar. According to the results of solubility tests, lamivudine dissolves quite successfully in 0.1 N HCl buffer. All of the evaluations described above were carried out with an all-fruit flavouring. The most recent round of testing consisted of using flavours such as strawberry and peppermint. Because of its delicious flavour, the strawberry flavour was voted the winner in this competition. Every batch of Film was analysed to determine if there were any differences in characteristics such as weight, hardness, thickness, and so on. The appearance of each batch of Films was evaluated and determined to be satisfactory across the board. Studies of in vitro dissolution were carried out on the best formulation, and the results revealed that one hundred percent of the drug was dissolved in 0.1N HCl after ten minutes had passed.
