Rânula é uma lesão que acomete glândula salivar menor, especialmente no assoalho bucal, resultando na obstrução parcial ou completa do ducto excretor glandular, com retenção da secreção. O tratamento dessa lesão inclui micromarsupialização e remoção cirúrgica por diferentes técnicas. Objetivo: Apresentar um estudo de caso sobre a técnica cirúrgica de drenagem associada à excisão cirúrgica no tratamento da rânula em paciente pediátrico. Relato de caso: Paciente do sexo masculino, 13 anos, apresentou cisto de retenção salivar e foi atendido em clínica-escola privada em Teresina (PI). Após o exame clínico e a formulação da hipótese de diagnóstico, o tratamento foi definido como aspiração e remoção. A lesão que se apresentava mais distendida foi tratada por meio de drenagem por micromarsupialização e posteriormente removida por excisão cirúrgica, tornando possível menor envolvimento de estruturas adjacentes. Conclusão: O diagnóstico clínico da rânula possibilita o tratamento mais adequado, com preservação de tecido impedindo a recidiva da lesão, entretanto deve-se sempre ter como auxílio o exame histopatológico.

Introdução: O cimento Sealer 26® contém resina epóxi associada ao hidróxido de cálcio, apresentando menor radiopacidade que alguns cimentos endodônticos. Com o intuito de melhorar essa propriedade, tem-se agregado iodofórmio ao pó do cimento. Entretanto, ao executar tal procedimento, desconhecem-se as possíveis alterações nas propriedades físicas e químicas do material. Objetivo: Avaliar a capacidade de selamento marginal apical, a solubilidade e o pH do Sealer 26® puro ou acrescido de iodofórmio em diversas proporções. Material e métodos: Foram manipuladas e submetidas ao teste de solubilidade três associações experimentais de Sealer 26®, puro ou acrescido de iodofórmio. Paralelamente, as combinações foram inseridas em tubos de polietileno e imersas em água destilada, e o pH das soluções foi avaliado nos períodos de 24 horas e 7 dias. Em seguida, 40 raízes de incisivos inferiores extraídos, subdivididos em quatro grupos de dez espécimes cada, foram retrobturados com uma das misturas anteriormente descritas. Imergiram-se as raízes em Rhodamine B, sob vácuo, por 72 horas. Concluída a imersão, os espécimes foram desgastados longitudinalmente, os fragmentos radiculares fotografados, as imagens digitalizadas e a infiltração apical medida pelo programa Image Tool. Os dados obtidos foram submetidos a análise estatística, com nível de significância de 5%. Resultados:Os testes de infiltração e solubilidade não demonstraram diferenças entre os grupos experimentais (p > 0,05). A análise do pH apresentou diferença apenas no período de 24 horas entre o grupo do Sealer 26®puro e o grupo com 1,1 g de iodofórmio (p < 0,05). Conclusão: A adição de iodofórmio ao Sealer 26®, nas proporções descritas, não alterou as propriedades de selamento marginal apical, a solubilidade nem o pH do cimento original.

There is a growing concern on the development of adequate materials to interact with the human body. Several researches have been conducted on the development of biomaterials for dental applications. Objective: This study aimed to determine the microstructural and mechanical properties of a nickel- based alloy, after the casting process. Material and methods: The alloy was melted through lost wax technique and centrifugation, by using blowtorch with liquefied petroleum gas. To evaluate the mechanical properties, tensile bond strength and microhardness tests were performed. The microstructural characterization was performed using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Statistical analyses were performed on microhardness results, through Student t test. A program for digital image processing was used to determine the percentage of the existing phases. Results and conclusion: The tensile strength was higher than that reported by the manufacturer, 559.39±25.63MPa versus 306 MPa, respectively. However, the yield strength was slightly lower, 218.71±29.75 MPa versus 258 MPa, reported by the manufacturer. The microhardness tests showed about 70 HV, far above the value informed by the manufacturer (21 HV). It can be affirmed with 95% confidence interval that the casting process did not alter the material’s hardness. The alloy’s microstructure is formed by a matrix with dendritic aspect and gray color and a second white interdendritic phase with equally distributed precipitates as well as porosities. EDS tests showed that the matrix is rich in nickel and chromium, the interdendritic second phase is rich in molybdenum and the precipitates in titanium or silicon. The matrix represents 86% of the area and the second phase 12%.

Cognitive Impairment and Mossy Fiber Sprouting in a Rat Model of Drug-resistant Epilepsy Induced by Lithium-pilocarpine
Authors: Wu Jing , Wang Likun , Huang Yuanxin , Wu Qian , Luo Xingmei , Li Yinghui , Ren Siying , Wu Guofeng
Published: September 2021

Background:

The mossy fiber sprouting (MFS) in the dentate gyrus is a common pathological
change of epilepsy. Previous studies suggested that it is associated with drug-resistant
epilepsy, and mossy cells control spontaneous seizures and spatial memory.

Methods:

We investigated the correlations among cognitive impairment, MFS, seizure frequency
and drug resistance in a rat model of epilepsy induced by lithium–pilocarpine. Phenytoin and
phenobarbital were used to screen drug resistance. Cognitive function and MFS were detected
through the novel object recognition (NOR) test, Morris water maze (MWM) test and Timm staining.

Results:

The results showed that object memory and spatial memory functions were both significantly
impaired in rats with epilepsy, and only spatial memory impairment was more severe in rats
with drug-resistant epilepsy. More frequent spontaneous seizures and more obvious MFS were observed
in the drug-resistant rats. The seizure frequency was significantly associated with the MWM
performance but not with the NOR performance in rats with epilepsy. The degree of MFS was significantly
associated with seizure frequency and spatial memory function.

Conclusion:

Taken together, these correlations among drug resistance, seizure frequency, spatial
memory impairment and MFS suggested the possibility of a common pathological mechanism.
More studies are needed to clarify the underlying mechanism behind these correlations and the detailed
role of MFS in epilepsy.
The mechanism of mossy cell change may be an important target for the treatment of seizures,
drug resistance and cognitive dysfunction in patients with epilepsy.

Published: September 2021

:

Tuberculosis (TB) and Diabetes Mellitus (DM) association poses the re-emerging
problem nowadays and challenge on the way towards a tuberculosis-free world. There are some peculiarities
in the immune function of DM patients, which make them more susceptible to infections,
including TB. This results in a higher prevalence of TB among DM patients (OR=1.15 according
to the last meta-analysis). Clinical manifestations of DM/TB often differ from the classical
course of the disease - these patients are more frequently symptomatic, more inclined to cavitary
disease and, according to some data, to lower lobe involvement. Data on multi-drug resistance prevalence
among DM/TB patients are controversial and need further research, especially in terms of
primary resistance. Higher frequency of adverse reactions, slower sputum conversion and foci regression
make treatment in this population more difficult and worsen outcomes. Potential measures
to lower the burden of co-morbidity are: new treatment regimens, bi-directional screening, proper
DM managing and controlling, testing for latent tuberculosis infection and its treatment, and new
vaccines development. Feasibility and efficacy of these measures are to be investigated in the context
of settings with different DM and TB prevalence and available resources.
Coronary Microvascular Dysfunction and Heart Failure with Preserved
Ejection Fraction - implications for Chronic Inflammatory Mechanisms

Published: September 2021

:

Coronary microvascular dysfunction (CMD) is now considered one of the key underlying
pathologies responsible for the development of both acute and chronic cardiac complications. It
has been long recognized that CMD contributes to coronary no-reflow, which occurs as an acute
complication during percutaneous coronary interventions. More recently, CMD was proposed to
play a mechanistic role in the development of left ventricle diastolic dysfunction in heart failure
with preserved ejection fraction (HFpEF). Emerging evidence indicates that a chronic low-grade
pro-inflammatory activation predisposes patients to both acute and chronic cardiovascular complications
raising the possibility that pro-inflammatory mediators serve as a mechanistic link in HFpEF.
Few recent studies have evaluated the role of the hyaluronan-CD44 axis in inflammation-related
cardiovascular pathologies, thus warranting further investigations. This review article summarizes
current evidence for the role of CMD in the development of HFpEF, focusing on molecular
mediators of chronic proinflammatory as well as oxidative stress mechanisms and possible therapeutic
approaches to consider for treatment and prevention.

According to Riskesdas 2018, the proportion of toga utilization in Indonesia was 24.6%, while in Bengkulu Province it was around 42%. From the research results, it is known that the implementation of the TOGA program in this research area is still lacking. This is partly because people do not know about the benefits of family medicinal plants so that the use of yard land is still not optimal. The second reason is the absence of special officers at the puskesmas who manage the activities of planting medicinal plants. Based on interviews with the village head of Harapan, it was found that the low utilization of the home page, garden or fields used to cultivate medicinal plants in order to meet family needs and the lack of community knowledge about family medicinal plants indicate that there was still a lack of socialization about family medicinal plants to health cadres as spearhead of health workers in conveying information and providing guidance to families and communities. The purpose of this community service activity is to develop a toga village in Harapan Village, Pondok Kelapa District, Central Bengkulu Regency by empowering families through Health Cadres. The method used in the implementation of the activity is using the concept of community nursing and family nursing (Family and Community Nursing Aproach) and using the Community Development (CD), Persuasive and Educational model. The results of the socialization showed that there was an increase in the knowledge of PKK cadres after participated in the socialization about family medicinal plants and simple medicine from Toga (p : 0.006), a demonstration toga was formed in the Harapan Village office yard and the residents' home page. The conclusion of this activity is that 2 family medicinal plant gardens have been formed in the village office yard and the residents' home page as a model robe for the local residents. It is hoped that residents can make gowns in their respective yards so that they become a source of simple medicine and first aid if there are people who are sick community.

A puddle is a condition where the water stops flowing in a certain area that is not a water body. In theory, a boezem building in Blimbing Village can help control the inundation and soak it into the ground. However, until now, there are still cases of inundation in Blimbing District. Therefore, this study aims to determine the existing conditions of drainage and boezem, and plan alternative buildings that can help the performance of boezem as a conservation-based inundation controller. From the analysis, the existing drainage and boezem cannot fully accommodate the design discharge. The inability of the existing boezem to accommodate all the total design flows leaves an inundation of 2,076 m3/s with a 2-year return period and 2,551 m3/s with a 5-year return period. Two conservation-based alternatives are offered to control the inundation. Based on technical and economic analysis, a 595-unit infiltration well was chosen in the boezem catchment area with total flood reduction of 22% and Rp's total fund. 3,276,869,973.16.Genangan merupakan kondisi dimana air berhenti mengalir pada suatu area tertentu yang bukan merupakan badan air. Adanyan bangunan boezem di Kelurahan Blimbing secara teori dapat membantu mengendalikan genangan dan meresapkannya ke dalam tanah, namun sampai saat ini masih terjadi kasus-kasus genangan di Kecamatan Blimbing. Maka dari itu penelitian ini bertujuan untuk Â mengetahui kondisi eksisting drainase dan boezem serta merencanakan alternatif bangunan yang dapat membantu kinerja boezem sebagai pengendali genangan berbasis konservasi. Dari hasil analisa, drainase dan boezem eksisting tidak dapat sepenuhnya menampung debit rancangan. Ketidakmampuan boezem eksisting dalam menampung seluruh debit rancangan total menyisakan genangan sebesar 2.076 m3/dt dengan kala ulang 2 tahun dan 2.551 m3/dt dengan kala ulang 5 tahun. Untuk mengendalikan genangan tersebut ditawarkan dua alternatif berbasis konservasi. Berdasarkan analisa teknis dan ekonimis dipilihlah pembangunan 595-unit sumur resapan pada catchment area boezem yang dapat mereduksi 22% debit genangan dengan total dana sebesar Rp. 3,276,869,973.16.

Drought is a natural disaster that occurs slowly but harms Sampang Regency people's life sustainability. Consider the negative impact of drought,Â  analyze the drought index and its distribution are necessary. This study aims to know drought level using Standardized Precipitation Index (SPI) and Palmer Drought Severity Index (PDSI), then to know their correlation with Southern Oscillation Index (SOI) that can represent El Nino Southern Oscillation (ENSO). Drought index with bigger correlation mapped by Inverse Distance Weighting method to know the distribution. SPI method produced the most severe drought in April 2004 on one month deficit period (-3.651). PDSI method developed the most severe drought in September 2001 (-20.628). Based on the PDSI average analysis results for the 1998-2017 period, it is well-known that drought disasters generally start in July and end in October, while the peak of drought occurs in September. The PDSI method has 60% conformity to the SOI value derived from the graphical visualization of the annual average surplus and deficit index, better than the SPI method that only scores 53%. The visualization of the drought distribution map shows that the Districts of Sampang, Torjun, and Camplong need to become prioritized to mitigate future drought disasters because they have a great potential for drought disasters compared to other districts.

The drought that is currently occurring in Indonesia has resulted in a prolonged lack of water supply for subsistence needs, agriculture, and economic activities. Reviewing the impact, analysis is needed for areas that have the potential for drought. There are several methods developed to analyze droughts, such as SPI (Standardized Precipitation Index) and RDI (Reconnaissance Drought Index), to know the level and characteristics of an area of drought. After analyzing the two indexes, a map of the distribution of drought was carried out using a GIS to make it easier to interpret the areas that experience drought potential in the Lekso watershed and to make efforts to mitigate the dangers of drought. The results showed that the peak of the drought with the RDI method of 1-month deficit occurred in May 2005 with the villages of Slumbung, Balerejo, Semen, Tulungrejo, and Soso. Based on the analysis of the suitability between the drought index and the SOI data, it is concluded that the drought index calculation of the RDI method has a higher percentage level of conformity than the SPI drought index method.Kekeringan dapat didefinisikan pengurangan persediaan air yang bersifat sementara secara signifikan di bawah normal. Bencana kekeringan yang terjadi di Indonesia saat ini mengakibatkan daerah kekurangan suplai air untuk kebutuhan hidup, pertanian, dan kegiatan ekonomiÂ  dalam masa yang berkepanjangan. Meninjau dampak yang ditimbulkan, maka diperlukan analisis untuk daerah-daerah yang memiliki potensi terjadinya bencana kekeringan. Terdapat beberapa metode yang dikembangkan untuk menganalisis kekeringan, seperti SPI (Standardized Precipitation Index) dan RDI (Reconnaissance Drought Index), sehingga mengetahui tingkat dan karakteristik kekeringan suatu daerah. Setelah melakukan analisis dengan kedua indeks tersebut dilakukan pengambaran peta sebaran kekeringan menggunakan Sistem Informasi Geografi sehingga mempermudah menginterpretasikan daerah yang mengalami potensi kekeringan pada DAS Lekso , serta dapat melakukan upaya-upaya pencegahan dan penanggulangan bahaya bencana kekeringan. hasil penelitian menunjukkan puncak kekeringan metode SPI periode defisitÂ  1 bulan terjadi Mei tahun 2005 dengan wilayah desa yaitu Desa Slumbung, Balerejo, Semen, Tulungrejo dan Soso. Sedangkan pada metode RDI , puncak kekeringan terjadi pada bulan Mei tahun 2005 dengan wilayah desa yang mengalami kekeringan yaitu Desa Slumbung,Â  Balerejo, Semen, Tulungrejo dan Soso. Berdasarkan analisis kesesuaian antara indeks kekeringan dengan data Southern Oscillation Indeks, disimpulkan bahwa perhitungan indeks kekeringan metode RDI memiliki prosentase tingkat kesesuaian lebih tinggi dibandingkan dengan metode indeks kekeringan SPI.

Ground stations in Indonesia arenâ€™t evenly distributed, whereas the resulted rainfall data is important. Then validation analysis with TRMM satellite data is required because it can cover a wide area, near real-time availability and fast access. This research aims to validate satellite data with observation data in the Grindulu watershed. Later, used to anticipate observation rainfall data that may be an error or unavailable. Validation methods used are Root Mean Squared Error (RMSE), Relative Error (RE), Nash Sutcliffe-Efficiency (NSE), and Correlation Coefficient (R). This research was done with two steps, those were TRMM data uncorrected and corrected, where the corrected data was done by calibration first. It showed that the best corrected TRMM data were found in a monthly period with a range of nine years of calibration in couple with one year of validation have a value of NSE = 0.929; R = 0.969; RMSE = 46.48 and RE = 8.9%. So, it showed that corrected TRMM data resulted have a better value than uncorrected data because the NSE and R values approaching one and have small values of RMSE and Relative Error. Overall, TRMM Satellite data can be used as an alternative hydrology data in the Grindulu watershed.Pos penakar hujan di Indonesia lokasinya masih kurang tersebar merata, padahal data hujan yang dihasilkan sangat penting. Maka diperlukan analisis validasi dengan data satelit TRMM karena dapat mencakup wilayah luas, tersedia secara near real-time dan aksesnya yang cepat. Penelitian ini bertujuan untuk memvalidasi data satelit dengan data observasi di DAS Grindulu yang datanya dianggap lengkap dan dapat diandalkan. Nantinya digunakan untuk mengantisipasi data curah hujan observasi yang mungkin error atau tidak tersedia. Metode validasi yang digunakan berupa Root Mean Squared Error (RMSE), Uji Kesalahan Relatif (KR), Nash Sutcliffe Efficiency (NSE) serta Koefisien Korelasi (R). Penelitian ini menggunakan dua tahap perhitungan, yaitu analisis validasi data tidak terkoreksi dan data terkoreksi, dimana data terkoreksi dilakukan kalibrasi data terlebih dahulu, hasil dari validasi data TRMM terkoreksi terbaik terdapat pada periode bulanan dengan rentang kalibrasi 9 tahun dan validasi 1 tahun dengan hasil NSE = 0,929; R = 0,969; RMSE = 46,48; KR = 8,9%. Hasil tersebut menunjukkan bahwa data TRMM terkoreksi menghasilkan nilai yang lebih baik dibandingan data TRMM tidak terkoreksi karena memiliki nilai NSE dan R yang mendekati satu dan nilai RMSE dan Kesalahan Relatifnya rendah. Secara kesluruhan, dapat disimpulkan bahwa data TRMM dapat digunakan sebagai data alternatif hidrologi di DAS Grindulu.

A dam is a structure built across a river to hold back water. Reservoirs created by dams not only suppress floods but also provide water for activities such as for water, irrigation, power generation, and flood control. But behind the benefits that can be obtained from dams, dams also have a large potential hazard in the form of the possibility of a dam break. The main causes of dam break are overtopping and pipping. So that analysis is needed related to dam break to minimize the impact. Based on the Zhong Xing HY21 software, the most severe impact of the break of the Gembong Dam was due to overtopping using the QInflow PMF design flood of 780,967 m3/s and resulted in an inundation area of 54,682 km2 with a maximum inundation height of 5,129 m. As a result of the break of the Gembong Dam, 37 villages downstream of the Gembong Dam were flooded. There are 80,819 people affected by this risk and it is stated that all affected villages are at the 4th hazard classification level or very high hazard.Â Bendungan adalah suatu struktur dibangun di sungai untuk menahan air. Waduk yang diciptakan oleh bendungan tidak hanya menekan banjir tapi juga menyediakan air untuk kegiatan seperti irigasi, pembangkit tenaga listrik, dan pengendali banjir. Namun di samping manfaatnya yang besar, pembangunan bendungan juga berpotensi membahayakan keselamatan masyarakat, yakni berupa keruntuhan bendungan. Penyebab utama dari keruntuhan bendungan adalah overtopping dan pipping. Sehingga diperlukan analisis terkait keruntuhan bendungan untuk meminimalisir dampak yang ditimbulkan. Berdasarkan software Zhong Xing HY21, dampak keruntuhan Bendungan Gembong yang paling parah disebabkan karena overtopping dengan menggunakan QInflow banjir desain PMF sebesar 780,967 m3/det dan menghasilkan luas genangan 54,682 km2 dengan tinggi genangan maksimum 5,129 m. Akibat keruntuhan Bendungan Gembong, 37 desa di hilir Bendungan Gembong terkena banjir. Terdadpat 80.819 jiwa penduduk terkena risiko tersebut dan dinyatakan bahwa seluruh desa terdampak berada pada tingkat klasifikasi bahaya ke-4 atau bahaya sangat tinggi.

Sutami Reservoir is a multipurpose reservoir with a water supply from Brantas River. The problem that occurs in the Brantas River is the decline in water quality due to the high discharge of agricultural, domestic, and industrial waste. The purpose of this study is to determine the distribution of water quality in 2015-2020 for the dry season using the Pollution Index, determine the regression model that best suits the variation of the pollution index value, and determine the pollution load capacity for Total-P in 2016 based on its trophic status. This research was conducted at the Upper, Middle, and Downstream Monitoring Stations at depths I (0.3 m), II (5 m), and III (10 m) for parameters BOD, COD, DO, NH3-N, TSS, and pH. From this study, it was found that the distribution of water quality of the Sutami Reservoir in 2015-2020 was classified as lightly polluted with the most appropriate regression model, namely the polynomial regression model. By comparing the pollution load capacity for Total-P in 2016 with the level of Total-P that enter the Sutami Reservoir, it was found that the level of Total-P that entered in the Sutami Reservoir had exceeded its proper capacity.Â Waduk Sutami merupakan waduk multiguna dengan pasokan air dari Sungai Brantas. Permasalahan yang terjadi di Sungai Brantas yaitu menurunnya kualitas air akibat tingginya buangan limbah pertanian, domestik, dan industri. Tujuan dari penelitian ini yaitu untuk menentukan sebaran karakteristik kualitas air dimusim kemarau tahun 2015-2020 dengan menggunakan Metode Indeks Pencemaran, menentukan model regresi yang paling sesuai dengan variasi nilai indeks pencemaran, serta menentukan daya tampung beban pencemaran Total-P tahun 2016 berdasarkan status trofiknya. Penelitian ini dilakukan pada Stasiun Monitoring Waduk Sutami Hulu, Tengah, dan Hilir pada kedalaman I (0.3 m), II (5 m), dan III (10 m) untuk parameter BOD, COD, DO, NH3-N, TSS dan pH. Dari penelitian ini didapatkan hasil sebaran karakteristik kualitas air Waduk Sutami tahun 2015-2020 tergolong tercemar ringan dengan model regresi yang paling sesuai yaitu model regresi polinomial. Dengan membandingkan nilai daya tampung beban pencemaran Total-P tahun 2016 dengan kadar yang masuk ke Waduk Sutami didapatkan bahwa kadar Total-P yang masuk ke Waduk Sutami telah melebihi daya tampung yang seharusnya.
