Static and Dynamic Impacts of Internet Use on Self-Rated Health among Adults in China: A Hybrid Model Analysis Based on National Panel Survey Data.

The widespread use of the Internet has a substantial impact on people's livelihoods, including health-related factors. Whether this impact is beneficial or harmful to people's health remains unclear. Some cross-sectional studies found static differences in the health status between Internet users and nonusers, whereas panel data studies found dynamic changes in an individuals' health over time, making the issue, including its causality, controversial.

Inequality and Mother's Age as Determinants of Breastfeeding Continuation in Bangladesh.

The World Health Organization recommends continuing breastfeeding up to 2 years of age or beyond for sound growth and development of children. In Bangladesh, continuation rates for breastfeeding have recently decreased and effective measures are required to counter this downward trend. Although recent years have seen economic development and reductions in poverty, Bangladesh still has the highest rate of child marriage worldwide.

Gene expression analysis of Arc mRNA as a neuronal cell activity marker in the hippocampus and amygdala in two-way active avoidance test in rats.

Introduction: Immediate early genes are widely used as neuronal cell activity markers in neuroscience. The present study investigated the relationship between their expression and abnormality in context fear conditioning.

Methods: The learning test (two-way active avoidance test) was conducted in male rats administered with nonselective muscarinic antagonist scopolamine or selective dopamine D1-like receptor antagonist SCH 23390 at a dose level of 2.

Localization of connexin 32 in spontaneous liver lesions of mice.

We examined the localization of connexin 32 (Cx32), a component of gap junctions, in 24-month-old male B6C3F1 mice with spontaneously occurring hepatocellular altered foci or tumors. Immunohistochemically, Cx32-staining intensity in cell-to-cell membranes of altered hepatocytes was decreased in eosinophilic foci and increased in basophilic foci as compared to those in intact hepatocytes. These alterations were enhanced in adenomas and carcinomas with both eosinophilic and basophilic cytoplasm.

Role of connexin 32 in acetaminophen toxicity in a knockout mice model.

Gap junctional intercellular communication (GJIC), by which glutathione (GSH) and inorganic ions are transmitted to neighboring cells, is recognized as being largely involved in toxic processes of chemicals. We examined acetaminophen (APAP)-induced hepatotoxicity clinicopathologically using male wild-type mice and mice lacking the gene for connexin32, a major gap junction protein in the liver [knockout (Cx32KO) mice]. When APAP was intraperitoneally administered at doses of 100, 200, or 300mg/kg, hepatic centrilobular necrosis with elevated plasma aminotransferase activities was observed in wild-type mice receiving 300mg/kg, and in Cx32KO mice given 100mg/kg or more.

Effectiveness of health sector reforms in reducing disparities in utilization of skilled birth attendants in Tanzania.

Improving maternal health is a Millennium Development Goal adopted at the 2000 Millennium Summit of the United Nations. As part of the improving maternal health in Tanzania, it has been recommended that skilled birth attendants be present at all births to help reduce the high maternal mortality ratio. However, utilization of these attendants varies across socio-economic groups.

The impact of Gonoshasthaya Kendra's Micro Health Insurance plan on antenatal care among poor women in rural Bangladesh.

Low utilization of antenatal care (ANC) by pregnant women, particularly in rural areas, is an obstacle to ensuring safe motherhood in Bangladesh. Currently, Micro Health Insurance (MHI) is being considered in many developing countries as a potential method for assuring greater access to health care, especially for the poor. So far, there is only limited evidence evaluating MHI schemes.

Background lesions during a 24-month observation period in connexin 32-deficient mice.

Connexin 32 (Cx32) is a major gap junction protein in the liver. Neoplastic and non-neoplastic lesions were examined in Cx32-deficient (Cx32KO) mice maintained for 24-month, and compared with those in wild-type mice as a corresponding control. In neoplastic lesions, hepatocellular carcinoma increased significantly only in male Cx32KO mice, suggesting that Cx32 deficiency may be related to their pathogenesis.

New casemix classification as an alternative method for budget allocation in thai oral healthcare service: a pilot study.

This study aimed to develop a new casemix classification system as an alternative method for the budget allocation of oral healthcare service (OHCS). Initially, the International Statistical of Diseases and Related Health Problem, 10th revision, Thai Modification (ICD-10-TM) related to OHCS was used for developing the software "Grouper". This model was designed to allow the translation of dental procedures into eight-digit codes.

Relationship between GST Yp induction and hepatocyte proliferation in rats treated with phase II drug metabolizing enzyme inducers.

Butylated hydroxyanisole (BHA) and 1,2-bis(2-pyridyl)ethylene (2PY-e) are phase II drug metabolizing enzyme inducers which cause hepatomegaly without hepatocyte hypertrophy and induce glutathione S-transferase Yp (GST Yp, pi-class GST), which is known as a tumor marker. To evaluate the relationship between GST Yp induction and hepatocyte proliferation, male F344/DuCrj rats were treated with BHA, 2PY-e, or phenobarbital (PB) for three or seven days. All three chemicals caused increases in liver weight after three and seven days.

Relationships between behavioral risk factors and dental care costs in a Japanese worksite.

Purpose: To identify the magnitude of dental care costs and examine the relationship between behavioral risk factors and dental care costs in a Japanese corporation.

Design: A one-time cross-sectional design was used with each employee as a unit of analysis.

Setting: The setting was a large Japanese corporation where Japan's standard health care insurance, including dental care coverage, was provided for all employees.

A novel model of continuous depletion of glutathione in mice treated with L-buthionine (S,R)-sulfoximine.

L-buthionine (S,R)-sulfoximine (BSO), an inhibitor of glutathione (GSH) synthesis, was administered to mice via drinking water for 14 days in order to establish an animal model with continuously depleted levels of GSH. No toxicity was observed at 20 mM BSO, even though a significant decrease in liver weight was observed at 30 mM BSO. GSH levels in the liver, kidney, brain, lung, heart, spleen, pancreas, small intestine, large intestine, skeletal muscle, plasma and blood cells from mice given 20 mM of BSO were all less than those from the control mice continuously throughout a 24-hr period.

[Patients' survey on regular check-up system in dental clinics].

This survey classified the issues involved in promoting the regular check-up system in dental clinics. The survey was conducted in two parts: interviews with 39 dental clinics and a questionnaire survey of 5,129 patients (response rate: 56.8%).
