Published: April 2019

As praias constituem sistemas dinâmicos onde ondas, marés, correntes e ventos interagem com sedimentos resultando em complexos processos hidro e morfodinâmicos, sendo os bancos arenosos uma das feições mais comuns nesses ambientes. O principal objetivo do presente trabalho foi analisar a variabilidade temporal da posição dos bancos da praia do Cassino (RS) com base em observações de alta resolução espaço-temporal utilizando técnicas de vídeo imageamento. A base de dados utilizada compreende o período entre abril de 2005 até abril de 2007. Os resultados indicam que a praia do Cassino é formada por um sistema de múltiplos bancos, com ocorrência mais comum de três bancos. Em especial foi registrado um evento de surgimento de um banco a partir da divisão do banco intermediário, acompanhado da gradual migração do banco externo costa afora até seu desaparecimento. Durante este processo a praia apresentou quatro bancos. As séries de dados indicaram diferentes componentes temporais, entre elas a subsazonal, a sazonal, a mensal e a semanal, sendo que esta última demonstrou maior representatividade na variabilidade total dos dados, apresentando ainda correlação significativa com a variabilidade diária da altura das ondas.

Na porção sul do Brasil, especialmente na região denominada Distrito Mineiro de Salto do Jacuí (Rio Grande do Sul), localizam-se os maiores depósitos mundiais de ágata, associados às rochas vulcânicas cretáceas da Formação Serra Geral, Bacia do Paraná. A ágata é uma variedade de calcedônia com bandamento, onde as bandas se dispõem de forma concêntrica ou paralela no interior de cavidades denominadas geodos. Na região, ocorre a valorizada ágata denominada Umbu, de cor azul escura e com elevada microporosidade que a torna adequada para tingimento com corantes. Neste trabalho procurou-se caracterizar a ágata sob o ponto de vista químico, isotópico e petrográfico por meio de técnicas analíticas diversas. Verifica-se que a temperatura de formação das ágatas varia de 23° a 65°C com base em isótopos de oxigênio. Estas temperaturas estão relacionadas com vários parâ- metros, tais como o teor total de sílica, a presença de impurezas (como o Fe2O3), o teor de água na estrutura e a cristalinidade. As amostras analisadas caracterizam-se por diferenças marcantes nos teores de elementos maiores e traços, na temperatura de cristalização e na cristalinidade, o que indica que apesar de serem ágatas provenientes de uma mesma região, ocorrem variações no seu processo de cristalização. Isto resulta nas diferentes estruturas e colorações apresentadas pelas ágatas da região de Salto do Jacuí.

This experiment aims to determine the correlation of total phenolic and flavonoid content of jati putih leaves fraction (Gmelina arborea Roxb.) towards Antioxidant activity . Sample was extracted by maceration method using ethanol 70% to obtain the ethanol extract (EE), followed by liquid-liquid extraction method to obtain fraction of ethyl acetate (EA) and n-Hexane (EH). The phytochemical screening and determination of total phenolic and flavonoid content were done by colorimetric method. Antioxidant activity were done by DPPH, FRAP and ABTS methods. Phytochemical screening showed positive results for flavonoids, phenolic and saponins. The largest total phenolic content was found on EA (11,59 µg/ml ± 0,3 %b/b EAG) and the largest total flavonoid content was on EA (3,88 µg/ml ± 0,02 %b/b EK). The total phenolic and flavonoid content of Jati putih leaves has a correlation with antioxidant activity. The coefficient correlation of activity on reducingDPPH radical was 56,7% (total of phenolic content) and 57,8% (total of flavonoid content) and on iron reduction power in FRAP method was 99,9% (total of phenolics and flavonoids content). The relationship with the activity in reducing radical ABTS obtained coefficient correlation of 57,0% and 58,1% for total phenolic and flavonoids contents, respectively.

Published: April 2019

Dissolution and solubility rates are very important parameters in designing a pharmaceutical dosage form, especially for oral drug administration. Oral drugs that have low dissolution rates often require high doses loading to improve the absorption and effectiveness in order to achieve therapeutic concentration. The increasing of drug dose is a less safe alternative solution, therefore researchers have developed physics, chemistry, and other modification in order to increase dissolution rate. These methods such as salt formation, prodrug formation, particle size reduction (micro-crystallization), co-grinding, crystal modification, micellar solubilization and complex formation, solid dispersion and self emulsifying. This review paper will focus on different methods that will be compared with the present of surfactant in these methods. The present of surfactants was able to overcome the limitation of each methods with a mechanism for reducing surface tension, micellar formation, reducing contact angle and increasing of wetting behaviour. Therefore, the present of surfactant in modification of drug dosage form could be considered to increase dissolution rate in order to achieve therapeutic effect.

Published: April 2019

Tingkat partisipasi masyarakat menjadi salah satu satu tolak ukur keberhasilan pelaksanaan Pemilu. Pada PILKADA serentak tahun 2018 di 171 daerah di Indonesia,tercatat partisipasi pemilih mencapai 73,24 % dari jumlah DPT yang lebih kecil dibanding partisipasi pemilih Pilkada tahun 2017 yang mencapai 74 %. (sumber : data KPU RI).
Berbagai cara dilakukan untuk mendongkrak tingkat partisipasi masyarakat termasuk Pemilih Remaja (pemilih pemula). Mengajak kaum milenial lebih aktif dalam Pemilu membutuhkan metode dan pendekatan yang tepat hingga mampu meningkatkan partisipasi mereka dalam Pemilu, salah satunya melalui pendidikan demokrasi dan HAM yang menjadi bagian pembelajaran Pendidikan Kewarganegaraan.Penelitian ini bertujuan mengetahui seberapa besar dampak perolehan Pendidikan kewarganegaraan terhadap peningkatan partisipasi pemilih remaja pada Pemilu.
Dari penelitian yang dilakukan terhadap 200 orang pemilih remaja di 3 Sekolah Menengah Atas dan 2 Perguruan Tinggi di Kota Medan, menunjukkan adanya dampak (pengaruh) yang signifikan pendidikan kewarganegaraan terhadap peningkatan partisipasi pemilih remaja dalam Pemilu. Penelitian mengambil studi kasus pada Pemilihan Gubernur dan Wakil Gubernur Sumatera Utara Tahun 2018 ini menunjukkan terdapat hubungan antara variabel Pendidikan Kewarganegaraan dengan tingkat Partisipasi Pemilih Remaja dan memiliki korelasi yang kuat. Terdapat koefisien 0,659 dan termasuk ke dalam korelasi kuat (karena nilainya lebih dari 0,5) maka tanda pada koefisien korelasi adalah positif, artinya semakin baik Pendidikan Kewarganegaraan yang diterima oleh Pemilih Remaja (Pemula) maka tingkat Partisipasinya juga akan semakin tinggi.

Abstract

OBJECTIVE
To evaluate long-term outcomes and identify factors associated with death or the need for revision surgery in dogs with permanent tracheostomies (PTs).

DESIGN
Retrospective cohort study.

ANIMALS
69 client-owned dogs that received a PT between January 2002 and June 2016 at 1 of 4 veterinary teaching hospitals.

PROCEDURES
Medical records were reviewed, and data extracted included signalment, history, clinical signs, radiographic and laryngeal examination findings, presence of esophageal abnormalities, date and reason for receiving a PT, postoperative complications, cause of death, and survival time. Dogs surviving < 2 weeks after receiving a PT were excluded.

RESULTS
Major complications occurred in 42 of 69 (61%) dogs, with aspiration pneumonia (13 [19%]), skinfold occlusion (13 [19%]), and stoma stenosis (12 [17%]) being most common. Revision surgery was performed in 24 of 69 (35%) dogs, most commonly because of stoma stenosis or skinfold occlusion (9/24 [38%] each). Brachycephalic dogs were more likely (OR, 3.5; 95% confidence interval, 1.2 to 10.2) to require revision surgery than were nonbrachycephalic dogs. The overall median survival time was 1,825 days, and dogs that received corticosteroids before receiving a PT, had tracheal collapse, or were older had shorter survival times.

CONCLUSIONS AND CLINICAL RELEVANCE
Results of the present study indicated that creation of a PT was a viable treatment option for obstructive upper airway diseases in dogs and that long-term survival after receiving a PT was possible; however, a PT may not reduce the risk of aspiration pneumonia in dogs.

Published: April 2019

Udang vaname merupakan salah satu jenis udang yang banyak dibudidayakan di Indonesia. Udang ini banyak digemari dan memiliki nilai ekonomis yang cukup tinggi, bahkan menjadi primadona dari Indonesia. Akan tetapi, kegiatan budidaya udang menghadapi permasalahan terkait faktor lingkungan, penyakit, pertumbuhan yang lambat, serta kematian massal. Hal ini berakibat menurunkan tingkat produktivitas udang vaname. Salah satu pendekatan alternatif yang dapat dilakukan untuk mengatasi permasalahan tersebut yaitu dengan penambahan prebiotik pada pakan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan prebiotik yang berbeda pada pakan terhadap pertumbuhan udang vaname (Litopanaeus vannamei). Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) yaitu dengan 4 perlakuan dan 3 ulangan, perlakuannya adalah Kontrol K ( pakan tanpa prebiotik), P1 (pakan pellet dengan penambahan prebiotik ubi 2%), P2 (pakan pellet dengan penambahan prebiotik kentang 2%), P3 ( pakan pellet dengan penambahan prebiotik ubi 1% dan kentang 1%). Data yang diperoleh dianalisa menggunakan analysis of variance (ANOVA) dengan tingkat signifikan 5%. Hasilnya menunjukkan bahwa tidak ada perbedaan yang signifikan antara perlakuannya untuk tingkat laju pertumbuhan spesifik, bobot mutlak, rasio konversi pakan, dan pertumbuhan mutlak.

Authors: Wahyuni Dewi , Priyanto Rudy , Nurani Henny 
Published: April 2019

Meat quality represents meat properties known by consumers and affects their acceptance. Feed is one of the factors affecting meat quality. Utilization of pineapple waste as a fiber source in cattle feeding is potential to reduce feed cost. Pineapple waste can be used as feed and as meat tenderizer. However, many believes that feeding pineapple waste to cattle distract beef quality. This study was aimed at assessing meat sensory quality of Brahman Cross cattle fed pineapple waste as fiber source. Six Brahman Cross (BX) cattle aged 2.5-3 years were used. The cattle were fattened for 120 days. Three cattle was fed rations containing concentrate and pineapple waste silage and the remaining cattle was fed rations containing concentrate and corn leaf silage. In the end of the study period, the animals were slaughtered and meat was cut based on the commercial slaughtering standard. Meat samples of Longissimus dorsi muscles were taken. Beef sample aging was conducted at 0ºC for 3 months. Measurements of beef characteristics were taken monthly. A completely randomized design was used. Data were subjected to a Kruskal Wallis test and meat physical characteristics were analysed by repetaed measurement analysis of variance. The parameters observed comprised pH values, tenderness, cooking loss, water holding capacity, meat colors (L*, a*, b* value), organoleptic test hedonic and hedonic quality (aroma, tenderness, color, and mucus). The results showed that the pineapple waste did not have significant influences on meat physical characteristics observed, except meat color a* values at two month aging, meat color L* value at three month aging. It was concluded that pineapple was could be used as a fiber source in beef cattle fattening with no negative effect on meat quality.

Comparative Evaluation of the Effect of Chlorhexidine Gluconate, Raw Propolis and Hydrogen Peroxide on Dental Plaque and Gingival Inflammation
Authors: Porwal Surbhi , Mathur Aditi , Shetty Neema , Manohar Balaji , Makhijani Barkha , Mundra Rohit 
Published: April 2019

Background: Plaque is the soft deposit that forms the biofilm consisting of microorganisms adhering to the tooth surface and is proved beyond doubt to be the initiator of gingival and periodontal disease. Plaque control is the mainstay in periodontal disease.
Aim: To compare the effect of 0.2% chlorhexidine gluconate, raw propolis and 3% hydrogen peroxide mouthwash on dental plaque and gingival inflammation.
Materials and Methods: Thirty subjects in the age group of 20-40 years were enrolled in the study. Plaque index and Modified Gingival Index were recorded at baseline and oral prophylaxis was performed. Subjects were then randomly divided into three groups (n=10) and were asked to rinse with 10ml mouthwash twice daily for 15 days. Group I received 0.2% chlorhexidine gluconate mouth wash, Group II raw propolis diluted with distilled water (1:1), and Group III 3% hydrogen peroxide (1:1) mouthwash. Subjects were recalled on 7 day and 28 day for re-evaluation and recording plaque index and modified gingival index. Statistical analysis was done to evaluate the efficacy of all the three mouthwashes.
Results: The results showed that all the three mouthwashes were effective in reducing plaque and gingival inflammation. Chlorhexidine gluconate 0.2% showed to be the most effective in reduction of dental plaque. Propolis was observed to be the most effective in reducing gingival inflammation over a period of 28 days.
Conclusion: Propolis can be effectively used as a mouthwash without any potential side effects as an alternative to chlorhexidine mouthwash in reducing gingival inflammation.

Published: April 2019

Background: Stress is playing a major role as an aetiologic factor in the initiation of many systemic diseases. Similarly, it is also thought to be an aetiologic factor in the progression of periodontal diseases.
Aim: The production of free radical species is associated with various inflammatory diseases and also during stressful conditions. Hence, an effort in the present study is done to correlate psychosocial stress and periodontitis using serum MDA as an oxidative stress biomarker.
Materials and Methods: A current cross-sectional study included 201 individuals between 20 to 60 years of age. A periodontal examination included Probing Pocket Depth, CAL, Plaque Index, and Gingival Index. According to CAL individuals were divided into four groups i.e. healthy, slight (CAL = 1-2 mm), moderate (CAL = 3-4 mm) and severe (CAL = ≥5 mm) periodontitis. Psychosocial stress of the individuals was evaluated using occupational stress index. Serum MDA level was evaluated using spectrochromatometer.
Results: Patients with stress demonstrated increased levels of MDA along with a higher loss of attachment.
Conclusion: The results revealed statistically significant association between psychosocial stress and periodontitis indicating psychosocial stress as a risk factor for developing periodontitis.
