The membrane-spanning domain (MSD) of human immunodeficiency virus type I (HIV-1) envelope glycoprotein (Env) is critical for its biological activity. Initial studies have defined an almost invariant "core" structure in the MSD and demonstrated that it is crucial for anchoring Env in the membrane and virus entry. We show here that amino acid substitutions in the MSD "core" do not influence spec...

background: occupation is one of the major parts of our daily lives that might cause a great amount of stress. stress and job burnout are linked together. the association between musculoskeletal disorders (msd) and burnout syndrome as a psychosocial factor was investigated previously. objectives: the aim of this study was to identify the role of occupational stress and burnout in musculoskeleta...

Can subjective replication generate valid and worthwhile knowledge? A theory of multimedia systems development (MSD) generated using a content analysis method is tested using a grounded theory method. The theory—that two distinct communities of software engineers and graphic designers exist within MSD—is confirmed. In fact, the test finds more differences and less commonalities. This finding ha...

Introduction. Musculoskeletal disorders (MSD) are common among nurses and can affect patient outcomes. There is a dearth of literature on MSD among Indian nurses. The study objective was to measure prevalence of MSD and their association with perceived work demands and sociodemographic variables among female nurses at a tertiary care hospital in rural India. Methods. A cross-sectional study was...

The aim of this study was to evaluate the effectiveness of multidimensional ergonomic intervention (MEI) model to reduce musculoskeletal discomfort (MSD) among street sweepers. A quasi-experimental study was conducted in Chiang Rai Province. The MEI model was designed on the basis of four core components: cognitive behavior therapy, ergonomic education training, stretching exercise, and the foa...

Previous studies of neural cell adhesion molecule (NCAM) cDNAs have revealed an alternatively spliced set of small exons (12A, 12B, 12C, and 12D) that encode a region in the extracellular portion of the molecule known as the muscle-specific domain (MSD). The entire MSD region can be expressed in skeletal muscle, heart, and skin; only exons 12A and 12D have been found in brain. These studies did...

the aim of this study was to investigate the effect of external intervention factor (types of music) on physical fitness factors in adolescent boys. 30 adolescent boys (9-12 years old, msd height, weight and bmi: 133.82.40 cm, 35.62.97 kg, and 19.91.21 kg/cm2), were selected and performed the tests in three stages (fast music, slow music, control) with counter balance method. in each stage, the...

BACKGROUND Farmers have an increased risk for musculoskeletal disorders (MSD) such as osteoarthritis of the hip, low back pain, and neck and upper limb complaints. The underlying mechanisms are not fully understood. Work-related exposures and inflammatory responses might be involved. Our objective was to identify plasma proteins that differentiated farmers with MSD from rural referents. METHO...

Musculoskeletal disorder (MSD) is a common problem among workers. In spite of the numerous reports on MSD in various specific groups of workers, few data on the prevalence in the general working population are available except for back pain. We analyzed the information collected through a nationwide survey in Taiwan in 1994 to estimate the prevalence of MSD by age, gender, and education level a...
