Abstract

Penelitian tentang isolasi dan aktivitas fermentasi bakteri asam asetat pada nira nipah (Nypa fruticans) bertujuan menentukan jenis dan karakterisasi dari bakteri asam asetat sampai tingkat genus. Isolasi dilakukan menggunakan media spesifik Pepton – Yeast ekstrak – Glukosa + Etanol untuk mengamati jenis bakteri yang berperan dalam aktivitas fermentasi. Identifikasi menggunakan metode standar dari Bergey’s Manual Determinative of Bacteriology. Diperoleh 6 isolat bakteri asam asetat yang berperan dalam fermentasi nira nipah. isolat yang tumbuh tergolong genus Acetobacter.  Dari aktivitas bakteri dalam proses fermentasi nira nipah menjadi asam asetat, diketahui pH maksimal (derajat keasaman) cuka nipah adalah 2-3. Nilai kandungan asam yang dihasilkan dalam fermentasi 25 ml adalah sebesar 9,36%, dengan kandungan alkohol yang terbentuk sebanyak 24,8%.   Kata kunci : isolasi, fermentasi, bakteri asam asetat

Abstract

Abstract The appropriate planning of orthodontic therapy with regard to appliance selection, information on the patient’s stage of somatic maturity is needed. Hand wrist maturity has been shown to be closely related with the pubertal growth spurt; therefore hand wrist radiographs have been recommended for indirect assesment of somatic maturity. However, the routine use of hand wrist radiographs has lately been questioned from the radiation-hygiene, safety point of view. In a recent cephalometric investigation, it was found that the frontal sinus development showed a growth rhythm similar to the body height development. Furthermore, it has been proposed that frontal sinus enlargement follows general bone growth but little evidence has been shown. The objective of this study was to investigate the correlation between frontal sinus depth and hand wrist maturity in Deuteromalayid group aged 7 to 17 years. A cross sectional study was conducted in 138 subjects (69 males, 69 females). The frontal sinus depth and hand wrist maturation was determined using Ertürk’s and Fishman’s method, respectively. The result of this study showed that there was a moderate correlation between frontal sinus depth and hand wrist maturity in males (r = 0.608) and females (r = 0.647).  From this study, it can be concluded that the usage of frontal sinus depth to substitute hand wrist maturity to assess the skeletal maturity is not appropriate enough. Key words: frontal sinus depth, hand wrist maturity, Deuteromalayid

Abstract

Cephalometric is extensively used to study the facial morphology that supports orthodontic diagnosis and treatment planning. Correct cephalometric analyses need reference values obtained from the same ethnic, gender and age population of orthodontic patients. Objective: To compare the difference of lateral cephalometric values between Australo-Melanesian and Deutero-Malay race in 16 to 20 years of age subjects with normal occlusion. Methods: An observational with cross-sectional design study on 200 subjects (100 males and 100 females) from Australo-Melanesian and Deutero-Malay race was performed. Lateral cephalometric radiographs were taken, traced and analyzed. Results: Mann Whitney U test showed significant differences on SNA angle with median 84° for Australo-Melanesian race and 83° for Deutero-Malay race. Lower lip distance to aesthetic line 3mm for Australo-Melanesian race and 1mm for Deutero-Malay race also showed significant difference. Independent t-test showed significant differences in FM angle with mean 27.45±4.49° for Australo-Melanesian race and 28.14±5.36° for Deutero-Malay race, and upper I to APg angle 36.28±4.72°for Australo-Melanesian race and 32.69±6.24° for Deutero-Malay race. Conclusion: The Australo-Melanesian race had more protruded maxilla to cranial base, more flat mandibular plane, more proclined upper incisors, and more frontal lower lip to aesthetic line compared to Deutero-Malay race.DOI: 10.14693/jdi.v20i1.127

Abstract

The final procedures of orthodontic treatment are bracket debonding and cleaning the remaining adhesive. Multi-step polishing system is the most common method used. The disadvantage of that system is long working time, because of the stages that should be done. Therefore, dental material manufacturer make an improvement to the system, to reduce several stages into one stage only. This new system is known as one-step polishing system. Objective: To compare the effect of one-step and multi-step polishing system on enamel roughness after orthodontic bracket debonding. Methods: Randomized control trial was conducted included twenty-eight maxillary premolar randomized into two polishing system; one-step OptraPol (Ivoclar, Vivadent) and multi-step AstroPol (Ivoclar, Vivadent). After bracket debonding, the remaining adhesive on each group was cleaned by subjective polishing system for ninety seconds using low speed handpiece. The enamel roughness was subjected to profilometer, registering two roughness parameters (Ra, Rz). Independent t-test was used to analyze the mean score of enamel roughness in each group. Results: There was no significant difference of enamel roughness between one-step and multi-step polishing system (p>0.005). Conclusion: One-step polishing system can produce a similar enamel roughness to multi-step polishing system after bracket debonding and adhesive cleaning.DOI: 10.14693/jdi.v19i3.136

Abstract

A few decades ago it was generally accepted from experimental studies, animal experiments, and epidemiological cohort studies that atherogenesis is linked to oxidative stress and that antioxidant supplementation, notably vitamin E supplementation, is associated with a low incidence of cardiovascular disease (CVD). This view led to the widespread use of vitamin E and other antioxidants for reducing CVD morbidity and mortality. In vitro and animal studies on antioxidant and anti-inflammatory properties of alpha- and gamma-tocopherols also found that these antioxidants had anti-inflammatory properties.

Abstract

Cardiovascular disease (CVD) incidence increases with age and is frequently higher in the elderly.(1) Therefore prevention of CVD in the elderly through management of risk factors is important in order to reduce the risk of coronary heart disease (CHD). There are several risk factors of CVD that can be modified, such as smoking, physical activity, and unhealthy diet. Cessation of smoking is the most potent measure to prevent thousands of CVD events and death

Abstract

Worldwide, the proportion of people aged 60 and over is growing faster than any other age group. It has been well-established that the aging process can be associated with increased susceptibility to chronic conditions, disability, and co-morbidity, which however may be minimized or even partially reversed by physical activity. The assessment of physical activity is becoming an increasingly important component in the evaluation of elderly persons. Nutritional intake and status play an essential role in determining the physical activity level potentially capable of minimizing the health burden of older persons. The objective of this study was to find out whether nutritional intake and status were correlated with physical activity in community-dwelling older persons. The study population included 219 aged 60 to 69 years, of whom complete measures of socio-demographic characteristics, nutritional status, nutritional intake and physical activity were obtained. Serum total protein, albumin, globulin and hemoglobin concentration were measured as nutritional indicators (biomarkers). The nutrient content of food intakes was analyzed and calculated by “Nutrisurvey” software. Analysis indicated that there was a significant correlation between nutritional biomarkers [total protein (r=-0.211; p=0.002) and globulin (r=-0.247; p=0.000)] and physical activity. Compared to other food intakes, intakes of carbohydrate (r=0.241; p=0.001) and animal protein (r=0.149; p=0.027) were significantly correlated with physical activity. Our findings lend support to the existence among healthy older persons of a relationship between nutrional intake and status and physical activity.
