Glutamine deficiency shifts the asthmatic state toward neutrophilic airway inflammation.

Background: The administration of L-glutamine (Gln) suppresses allergic airway inflammation via the rapid upregulation of MAPK phosphatase (MKP)-1, which functions as a negative regulator of inflammation by deactivating p38 and JNK mitogen-activated protein kinases (MAPKs). However, the role of endogenous Gln remains to be elucidated. Therefore, we investigated the mechanism by which endogenous Gln regulates MKP-1 induction and allergic airway inflammation in an ovalbumin-based murine asthma model.

Family Avoidance of Communication about Cancer: A Dyadic Examination.

Purpose: This study aimed to examine the following questions: to what extent do patients and caregivers perceive their family members to be avoidant of communication regarding patient's cancer, and to what extent do these perceptions interrelate; and how do such perceptions influence their own and each other's communication behaviors, communication outcome, mental health, and quality of life.

Materials And Methods: A national survey was performed with 990 patient-caregiver dyads (participation rate, 76.2%).

Declining hepatitis A antibody seroprevalence in the Korean military personnel.

We retrospectively analyzed serological test results for anti-hepatitis A virus immunoglobulin G (anti-HAV IgG) of sera collected from 779 military personnel during January 2001 to May 2008. The overall seroprevalence of anti-HAV IgG of the subjects was 17.5% (95% confidence interval [CI], 14.

Facial wrinkles as a predictor of decreased renal function.

Aims: Oxidative stress generated either by exogenous or endogenous sources can lead to progressive organ damage and skin ageing over a long period of time. Moreover, some dermatological signs are independent of chronological ageing, and may reflect the long-term redox state of internal organs. Therefore, we hypothesized that there might be an association between facial wrinkles and decreased renal function, an oxidative stress-related disease.

[Mercuric chloride induces apoptosis in MDCK cells].

Objectives: Mercury is a hazardous organ-specific environmental contaminant. It exists in a wide variety of physical and chemical states, each of which has unique characteristics for the target organ specificity. Exposure to mercury vapor and to organic mercury compounds specifically affects the CNS, while the kidney is the target organ for inorganic Hg compounds.
