BACKGROUND The proportion of elderly people in the population is growing, and Korea has one of the fastest growing populations among the world's major regions. The objective of this study was to examine the effects of physical activity on the health and quality of life of elderly Korean people. METHODS A nationally representative sample of 2,853 elderly Korean people (1,239 males and 1,614 fe...

Circadian clocks drive rhythmic physiology and metabolism to optimize plant growth and performance under daily environmental fluctuations caused by the rotation of the planet. Photosynthesis is a key metabolic process that must be appropriately timed to the light-dark cycle. The circadian clock contributes to the regulation of photosynthesis, and in turn the daily accumulation of sugars from ph...

BACKGROUND Expert bodies and health organisations recommend that adults undertake at least 150 min.week(-1) of moderate-intensity physical activity (MPA). However, the underpinning data largely emanate from studies of populations of European descent. It is unclear whether this level of activity is appropriate for other ethnic groups, particularly South Asians, who have increased cardio-metaboli...

The combination of high strength and toughness, excellent wear resistance and moderate density makes zirconia-toughened alumina (ZTA) a favorable ceramic, and the foam version of it may also exhibit excellent properties. Here, ZTA foams were prepared by the polymer sponge replication method. We developed an immersion infiltration approach with simple equipment and operations to fill the hollow ...

The combined effect of environment and diet in shaping the gut microbiota remains largely unknown. This knowledge, however, is important for animal welfare and safe food production. For these reasons, we determined the effect of experimental units on the chicken cecum microbiota for a full factorial experiment where we tested the combined effect of room, diet, and antimicrobial treatment. By Il...

OBJECTIVE To determine the effect of duration of application of mouth gag on Temporomandibular (TM) joint pain and trismus after tonsillectomy. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Department of ENT and Head and Neck Surgery, Combined Military Hospital, Nowshera, from February to July 2012. METHODOLOGY A total of 40 patients undergoing tonsillectomy, in mouth openin...

At sites of vessel wall damage, the primary hemostatic reaction involves platelet and fibrin deposition. At these sites, circulating leukocytes marginate and become activated. Adhered platelets can support leukocyte localization; however, the role of fibrin in this respect is not known. We studied the adhesion of human neutrophils (polymorphonuclear leukocytes [PMNs]) to endothelial extracellul...

The deep shoal of Punta del Faro (Ligurian Sea, Mediterranean Sea) is a mesophotic rocky elevation hosting complex animal forests threatened by fishing activities. To identify appropriate conservation measures and set reference example for similar cases, we present detailed characterization its megabenthic communities quantification the pressure. results highlight high natural value area, prese...

OBJECTIVE To compare different surface treatments of lithium disilicate-based ceramic on bond strengths to composite. METHODS Lithium disilicate-based ceramic microbars (1 mm × 1 mm × 6 mm) were produced and abraded using diamond (D) or CoJet sandblasting (C), etched using phosphoric acid (P) or hydrofluoric acid (H) and silanised (S). A total of 12 surface treatments were adopted: D, DP, DH,...
