Performance Evaluation of a miniPET Camera for Brain Scanning  [PDF]
Arif Mahmud, Md. Moshiur Rahman
International Journal of Medical Physics,Clinical Engineering and Radiation Oncology (IJMPCERO) , 2015, DOI: 10.4236/ijmpcero.2015.41010
Abstract:
A nuclear miniPET camera was constructed with 2 bucket rings, each having 8 BGO detector modules for brain scanning. After calibration of the camera, an experimental investigation of sensitivity was carried out to evaluate the performance of this PET scanner. The characteristics of NECR were examined for comparisons of count rate considering the statistical noise due to scattered and random events. NECR performance was observed using 10 cm diameter phantom filled with 1 L water and 240 MBq of 18F. All data were acquired in 2D acquisition mode but without septa. Randoms were estimated by introducing delay into the coincidence circuit which was an extra 100 ns time delay. Multiples were recorded simultaneously with the prompt and delayed events. The true plus scattered coincidence events were calculated as the difference between prompt and random plus multiple events. After recording all the data, the noise equivalent count rate (NECR) was calculated and graphically presented. It is observed that NEC value is significantly lower than other similar scanners. Comparing the individual components of the count rate, a much higher randoms rate is observed for the camera because of the absence of any side shielding, so that out of field activity contributes significantly to the randoms rate and hence reduces the NECR value.

Andrew Pus, Michiko Moriyama, Mariko Uno, Md Moshiur Rahman
Health (Health) , 2016, DOI: 10.4236/health.2016.814158
Abstract: Obesity and overweight are complex phenomena due to causes and consequences as these are the predisposing factors for developing lifestyle-related diseases. In the recent times, obesity and chronic diseases are being taken very seriously than ever before. Once upon a time, obesity was considered as a problem only in developed countries, now it is of a serious concern in low- and middle-income countries. In Papua New Guinea (PNG), a few studies have been conducted on obesity-related issues. However, there is not enough data on obesity to clearly understand about the leading contributing factors. Our research group designed this study to assess the influencing factors of obesity and as well as to identify the principal cause. It is a descriptive study, used structured and semi-structured interview and survey questionnaire. This study was conducted in the capital city of PNG, Port Moresby, and recruited 87 adults aged 30 - 50 years. According to interview and analysis findings, the contributing factors of obesity are less physical movement, unhealthy diet, lifestyle, cultural value system, low education and social system. Government strategies and initiatives are not strong enough to educate and motivate the community people. This study suggests developing an effective coordination among all stakeholders to ensure quality education and increase awareness to prevent obesity and its complications. The standard health policies and strategies are also recommended at the local, national and international level with strong commitment.

Kana Kazawa, Susumu Iwamoto, Md Moshiur Rahman, Michiko Moriyama
Health (Health) , 2017, DOI: 10.4236/health.2017.94055
Abstract:
The number of patients with mental disorders is increasing all over the world and they have a high prevalence of physical complications. To analyze and compare the cost of mental disorders with the total medical costs such as mental disorders and physical disorders, we analyzed the cost that patients with mental disorders incurred. We investigated the distribution of medical costs and the characteristics of diseases by using the health insurance claims of people in City A, Japan from March 2013 to February 2014. The subjects had one or more of 4 mental disorders: schizophrenia, alcohol related disorders, bipolar disorder, and depressive episode. As a result, the total number of patients who met inclusion criteria per year was 7403 (6522 outpatients and 881 inpatients). It was revealed that the hospitalization rate of patients with mental disorders increased with age, and many inpatients stayed in hospital for a long time. Also, it was revealed that many patients with mental disorders were in complicated condition with more than one mental or physical disorders and incurred medical costs for these comorbidities. In conclusion, this analysis indicated that many patients with mental disorders switch from attending the outpatient department to hospitalization as they become older. Further, they incurred a lot of medical expenses for complication management. To improve their QOL, comprehensive assessment of their mental/ physical health, self-management education, coordination of services, and support for decision making regarding treatment are necessary.
Analysis of the Incidence of Hepatitis B and Hepatitis C and Association with Socio-Economic Factors in Various Regions in China  [PDF]
Ying’ai Cui, Michiko Moriyama, Md Moshiur Rahman
Health (Health) , 2018, DOI: 10.4236/health.2018.109093
Abstract: The incidence of liver cancer in China accounts for more than half of the world, and the majority of them is caused by hepatitis B and hepatitis C. China is known as a great contributor to hepatitis. The Chinese government has implemented a series of preventive measures to solve this problem, especially the policy of free hepatitis B vaccination for newborn babies and effectively reduced the incidence of hepatitis. The incidence of infectious diseases is often related to socio-economic factors. Therefore, we used data on the incidence of hepatitis B and C and socioeconomic factors to analyze and find out the relationship among them in various regions. There were high incidence areas and low incidence areas in China, and the high incidence area of hepatitis B was also the high incidence area of hepatitis C. Especially in Xinjiang, the highest incidence of hepatitis B and hepatitis C was observed at the same time. The incidence of hepatitis B and hepatitis C was more affected by regional economic factors. The economic factors in low incidence areas of hepatitis were better than those in high incidence areas. There was a negative correlation between economic factors and the incidence of hepatitis. In conclusion, in economically developed areas, the government has invested more money and resources in public health and people’s health awareness in comparison to underdeveloped areas. In the future, various preventive strategies should be carried out according to the background of different regions.

Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.49A2001
Abstract:

Calcium hypochlorite commercially known as bleaching powder is used as a bleaching agent in shrimp processing industries in many countries and known to effect biochemical alteration in shrimp muscle. Studies were, therefore, undertaken to determine their effect in different concentrations viz., 10, 20, 30, 40 and 50 ppm with different time intervals on the quality of head-on, headless shell-on and peeled giant freshwater prawn (Macrobrachium rosenbergii) by determining biochemical and organoleptic aspects. Myofibrillar protein solubility of fresh head-on, headless shell-on and peeled samples were 90.5%, 90% and 88%, respectively indicating a gradual decrease in protein solubility with increasing concentration of bleaching powder. Decrease in protein solubility was also higher in samples kept at longer duration in different concentration of bleaching powder. At a given concentration of 50 ppm for 30 min treatment, the loss of myofibrillar protein was higher (26.14%) in peeled samples than those of head-on and headless shell-on samples (20.44% and 21.11%). Shelf life of bleaching powder treated prawn samples was found to be reduced to 4 - 5 days in iced condition compared to 6 - 7 days for control samples. Peeled samples were also found to be more susceptible to bleaching powder than that of head-on and headless shell-on samples.

Health (Health) , 2017, DOI: 10.4236/health.2017.91012
Abstract: Background: The prevention of cardiovascular disease (CVD) can substantially contribute to reducing the mortality rate across countries. The level of interest in cholesterol among experts increases when the subjects are elderly and obese individuals. However, specialists do not recommend that children should receive the cholesterol test. The objective of this study was to investigate the distribution of cholesterol levels among the children of public school and their parents’ lifestyles that are associated with cholesterol levels, and to assess the need for and utility of cholesterol testing in school settings. Methods: The study investigated a group of 226 fourth-grade public school children aged between 9 and 10 years and guardians in Akitakatacity of Hiroshima Prefecture, Japan. Multiple regression analyses were performed with the logarithmic value of cholesterol levels as a response variable, awareness about lifestyles and health of children as an explanatory variable, and child’s sex and body mass index (BMI) as moderating variables. Using questionnaires about lifestyles, the step-down procedure was applied in multiple regression analyses to narrow down relevant lifestyle variables. Results: The percentage of children with the high total cholesterol (TC) value was about 15 and with low-density lipoprotein (LDL) cholesterol value was about 10. Children with low high-density lipoprotein (HDL) cholesterol value were 5%. Treatment was not required according to the comprehensive assessment. Cholesterol levels were associated with the situation of the children and their guardians as follows, guardian need to consider the food, and child has the correct knowledge about food like how to eat snacks. Conclusions: Children had poor cholesterol levels. From childhood, along with the parents, there is a need to learn about appropriate level of cholesterol for CVD prevention.

Abstract: Background: Japan has the highest aging people accounting 33.8 million with the rate of 26.7% in 2015. Although, public long-term care insurance services support people age 40 years and above, most of the users are 85 years and over due to their more vulnerability for getting sick. This study describes the physical, mental and social status of the elderly people aged 85 years and over, who were living alone at home. Method: A cross-sectional study was conducted between November 2016 and March 2017 in the island of Kure city, Hiroshima, Japan. A structured questionnaire and scales were used for data collection and documentation of physical measurements. Descriptive analysis was used. Result: A total of 190 subjects were participated, and the data were analyzed. The age range of the subjects was 85 to 98 years, and 68.4% of them were 85 to 89 years old. Male and female ratio was 21.6% vs 78.4%. Subjects of 17.4% continued their occupation at the time of the study period and most of them involved in agricultural work (93.9%). A certain percentage of the subjects had abnormal physical, mental and social difficulties and need additional support from family, friends, relatives, and community. Conclusion: Early detection and intervention such as disease management, nutritional support, and human support are required. The findings suggested policy makers to predict the burden and provide necessary care for these elderly people. It is necessary to aware family, friends, relatives, community and government supporting staff to provide information on correct recognition and usages of long-term care insurance services for these elder people.

Md. Moshiur Rahman,Md. Golam Rabbani,Mohammad Atikur Rahman,Md. Farid Uddin
Pakistan Journal of Biological Sciences , 2002,
Abstract: The effects of different cytokinins viz. BAP, 2iP and Kn each at 5 mg/l alone or in combination on shoot multiplication and auxins viz. IBA, NAA in different concentrations (i.e. 0, 1, 2, 3, 4 and 5 mg/l) on rooting of banana cv. Sabri were investigated. The rate of shoot multiplication varied in different cytokinin treatments. Among the treatments, MS medium supplemented with 5 mg/l each of BAP+Kn produced the highest number of shoots/explant (3.11), while no shoot multiplication was observed in control (i.e. no cytokinin). On the other hand, the number of shoots responded for rooting and their survivability were higher with NAA than IBA. MS medium supplemented with 4 mg/l NAA produced the highest number of roots/shoot (20) whereas 1 mg/l IBA produced the minimum number of roots/shoot (2.4). Plantlets grown without any auxin in the medium gave the least number of root (1). The micro-propagated Sabri plantlets were successfully transferred from pot to the field and 100% plantlets survived in field environment.

Pakistan Journal of Biological Sciences , 2002,
Abstract: The effect of corm size and depth of planting was studied on the growth and flowering of gladiolus cv. Friendship using the combination of four corm sizes (15, 10, 5 and 3 g) and three planting depths planting (10.0, 7.5 and 5.0 cm). Corm size had significant influence on all the parameters studied. Large corm (15 g) took shortest time to complete 80% emergence (15.89 days) and flower initiation (60.44 days). The depth of planting had no marked effect on the parameters studied except percent lodging of plant. The highest lodging of plants (19.83%) was observed in shallowest depth of planting (5.0 cm), and the lowest (7.91%) was found in deepest planting depth (10.0 cm). The combined effect of corm size and depth of planting had significant effect on all the parameters studied except number of spikelets per plant. The highest plant height (97.56 cm), number of leaves (62.33), length of flower stalk (26.07 cm) and lodging of plants (33.14%) in the treatment combination of large sized corm planted at 5.0 cm depth and the lowest in the treatment combination of very small corm with 10 cm depth.
