Effect of roasting, brewing/cooking techniques on the bioactive compounds of coffee: Benefits on human health as a functional food

Coffee beverage is one of the most popular beverages worldwide and because of its proved health benefits, it may be regarded as functional food. The potential functional properties of coffee beverage have been associated with its bioactive compounds including caffeine, chlorogenic acids, and melanoidins which are Maillard reaction products. The extraction of coffee soluble from the roasted and ground coffee seed is a complex operation and brewing/cooking method plays an important role on the extraction and amount of the key compounds in the coffee beverage. This review provides how the roasting level and brewing techniques affect the key compounds, physicochemical attributes, and health of coffee beverage. The role of compounds caffeine, chlorogenic acids, melanoidins and the diterpenes cafestol and kahweol in the body are reviewed along with their impact on health by examining the results of the studies involving the coffee consumption. According to the reviewed studies daily intake of 2 to 3 cups of coffee beverage is safe and may support metabolic health, mental health, enhance mood, increase alertness, be effective against hypertension, help us to fight depression, prevent several chronical disease risks including type 2 diabetes, Alzheimer’s and Parkinson’s diseases and degenerative diseases, such as cancer like liver cancer, cardiovascular disorders. However, some data implies the negative effects on health that it may be cautious for pregnant women and need to limit coffee consumption no more than 300 mg/d of caffeine.

Correlation between vitamin D serum level and total IgE in asthmatic children

Asthma is a chronical disease of the airways characterized by reversible obstruction of the bronchi and airway inflammation. In recent decades, the scientific interest of the vitamin D system and its role in development of asthma and other alergic diseases has been increased. Aims of this study are to mesure and compare the serum level of 25 OHD in asthmatic and healthy children and corelate the level of 25OHD and total IgE in asthmatic children. This prospective study includes 70 children at age 2 to 14, of which 32 are children with diagnosed asthma and 38 healthy children. In both of the groups the serum level of 25 OHD was measured and by the results 18 % of the healthy children (C) and 28% of the asthma children (E) had 25OHD deficiency, 45% of C and 50% of E were insufficient and 37 % of C / 22% of E were with normal 25 OHD serum level. The mean level of 25OHD in C was 27,83 +/- 10,24 and in E 20,9 ng/ml +/- 10,72. The mean levels in both groups had statistic significant difference with p-value < 0,05. According to age no statistic significant difference was found in both of the groups. There was a statisticaly significant decreased serum level of 25 OHD in asthmatic females.In the examined group (children with asthma) there was a negative linear correlation (association) of the level of 25OHD and total IgE serum level with r=- 0,55 Vitamin D serum level measurements in asthma patients gives the possibility for discovering the connection between its deficiency and development of asthma symptoms.

Determinant of Diabetes Mellitus Focusing on Differences of Indonesian Culture: Case Studies in the Java and Outer Java Region in Indonesia

Background: In 2017, Indonesia was ranked 6th in the world, with 10.3 million DM sufferers. Indonesia consists of many islands with diverse communities, diverse social and cultural environments, which allow different factors to affect the increasing number of DM cases. Objective: This research objective is to analyze the differences in the factors of the social environment, cultural environment, knowledge and behavior that are potential to DM in Java and outside Java. Methods: This research uses a quantitative approach with independent sample t-test data analysis techniques. The population was DM type 2 patients, with a sample size of 294 people. The technique was to determine the sample by accidental sampling in patients who seek treatment during prolanis (chronical disease management program) activities. The independent variables consist of social environment, cultural environment, knowledge and behavior. The dependent variable is DM disease. Data is equipped with qualitative data. Results: The results showed that there were differences between Javanese and Outer Java respondents on social environmental factors (t value 6.682), cultural environment (t value 5.752), knowledge (t value 7.079) and behavior (t value 16.579) with each Sig 0.000 value. All factors that are variables in this study have higher values in the Java region compared to those outside Java, and the highest difference is in the social environment variable (average difference of 3,979), which has an effect on very high behavioral differences (average differences average 6,037). Conclusion: It can be concluded that there are differences in the social environment, cultural environment, knowledge, and behavior that influence the incidence of diabetes mellitus in Indonesian society.

PENGARUH PEMBERIAN QUERCETIN TERHADAP KADAR LEPTIN SERUM TIKUS WISTAR YANG DIBERI DIET TINGGI LEMAK

Obesity, one of the degenerative diseases, is a risk factor for chronical disease and an ultimate cause of metabolic syndrome which ismarked by the raising level of leptin on blood (hyperleptinemia). Metabolic syndrome is marked by the size of the waist is more than 40 inchfor man or 35 inch for woman, hypertension, hyperglycemia, high level of triglyceride, and the level of HDL (high-density lipoprotein) is low.This research is aimed to know the giving of quercetin (which has high anti oxide activities) on the declining level of leptin to the giving of DIO(Diet Induced Obesity). An experimental study using Post Test Control Group was done to the experimental wistar rats. Samples werechosen by using randomized complete block design. Rats were treated for 8 weeks. The dose of given quercetin were 2 mg/kgBB/day, 10mg/kgBB/day, and 50 mg/kgBB/day during the last 8 weeks of research. The variable measured in this research is the level of leptin onblood. Based on the experiment, quercetin is proven that gives influence to the level of leptin on obesity wistar rats’ serum compare to the givenlevel of leptin on controlled rats. There is different average on the level of leptin on wistar rats’ serum which being obesity on each grouptreatment. The giving of quercetin have significant correlation (p<0.05) with the level of leptin on wistar rats’ serum which being obesity (r = -0.704, p = 0.001). The conclusion from this research is the giving of quercetin to obesity rats for 8 weeks can decline the level of leptin onblood.Keywords: quercetin, leptin, high fat diet

Various clinical manifestations of brucellosis infection

Introduction. Brucellosis is an acute, subacute or chronical disease, from the zoonosis group, caused by various types of bacteria belonging to genus Brucellae. It is transmitted to humans from domestic animals: goats, sheep, cattle, pigs and dogs. The course of the disease may either be asymptomatic, or produce a variety of clinical manifestations, ranging from light ones to extremely severe clinical forms. The aim of the study was to follow the clinical features of brucella infection in the hospital-treated patients, as well as its course and outcome. Material and Methods. The investigation included 15 patients, treated for brucella infection at the Clinic for infectious diseases during the last two years (2004 and 2005). Results. All patients were adults, their age ranged from 18 to 71, 49.96 on average. The epidemiological questionnaire was positive in all patients, confirming contacts with the ailing animals, or consumption of cheese made from milk of diseased animals. They all exhibited the classic symptoms - increased body temperature and shiver, fever, sweating, malaise and headache, the so called flu like state. The serum agglutination test was positive in respect to brucellosis, the titre ranged from 1:80 to 1:1280. Eight patients suffered excessive back pain, accompanied with impeded walk. In half of them magnetic resonance imaging confirmed the spondylodiscitis diagnosis. Three patients had clinical features of knee arthritis, two had bronchopneumonia, one pancreatitis, and one developed the signs of an acute kidney insufficiency. The outcome was favorable in all patients - They recuperated or healed completely. In one patient a relapse occurred, leading to the chronic course of the illness. Discussion. Although predominantly Mediterranean Brucellosis is a worldwide spread disease. During the last two years, an increased incidence of the disease has been observed. Conclusion. Due to the variety of clinical futures and the possibility of numerous complications and sequelae, brucella infection should be always taken into consideration while diagnosing undefined febrile states.

Application of Circular Statistics in Pulmonary Diseases by Blood Gas Analysis

Attention is focused on the presentation of circular statistics with directional data, since biologists and physicians are often confronted with such statistical problems. The methodological properties of circular statistics are elaborated by means of data of arterial blood gas changes during exercise in children with cystic fibrosis. The present study demonstrates that performance and discrimination into different severity groups in this chronical disease can be achieved by this statistical method and that analogous problems in biology and medicine could be resolved in the same way.
