Entamoeba histolytica was first cultured in vitro in 1925 (Boeck and Drbohlav, 1925) but has not yet been grown in the absence of living bacteria. Experimentally the dependence of E. histolytica on living bacteria in the intestine is well illustrated by the inability of E. histolytica to survive and invade the bowel wall of germ-free guinea-pigs (Phillips, Wolfe, Rees, Gordon, Wright, and Reyni...

Greenhouse and field experiments showed that conidia of the fungal pathogen, Phoma commelinicola, exhibited bioherbicidal activity against spreading dayflower (Commelina diffusa) seedlings when applied at concentrations of 10 to 10 conidia·mL. Greenhouse tests determined an optimal temperature for conidial germination of 25 °C–30 °C, and that sporulation occurred on several solid growth media. ...

Dew is one of the important moisture sources in many arid and semiarid regions. The knowledge origin dew under various climatic conditions still lacking. Isotopic variations can preserve information about formation mechanisms. Therefore, isotopic compositions precipitation (δ2H, δ18O, δ17O, d-excess, lc-excess 17O-excess) were investigated at three sites with different (i.e., Gobabeb extremely ...

Transient shape changes of organelles translocating along microtubules are directly visualized in thinly spread cytoplasmic processes of the marine foraminifer. Allogromia laticollaris, by a combination of high-resolution video-enhanced microscopy and fast-freezing electron microscopy. The interacting side of the organelle flattens upon binding to a microtubule, as if to maximize contact with i...

Emotional tearing is a poorly understood behavior that is considered uniquely human. In mice, tears serve as a chemosignal. We therefore hypothesized that human tears may similarly serve a chemosignaling function. We found that merely sniffing negative-emotion-related odorless tears obtained from women donors induced reductions in sexual appeal attributed by men to pictures of women's faces. Mo...

The fact that water is the most important factor of life on earth is not a new concept. Alteration and reduction in the amount of precipitation, population explosion and contamination of underground water pressurize governments severely to find solution for water resources. The air moisture is one of fresh water resources which has not been noticed and well exploited. In this study proper place...

PURPOSE To review outcomes of arthroscopic repair of rotator cuff tears using absorbable anchors with a single-row technique. METHODS 66 patients underwent arthroscopic repair for rotator cuff tears using absorbable anchors with a single-row technique. 51 of them aged 37 to 73 (mean, 57) years had been followed up for a mean of 29 (range, 20-37) months. The extent of the tear was classified a...

BACKGROUND The pattern of lateral meniscus tears observed in anterior cruciate ligament (ACL)-injured subjects varies greatly and determines subsequent management. Certain tear patterns with major biomechanical consequences should be repaired in a timely manner. Knowledge about risk factors for such tears may help to identify patients in the early posttraumatic phase and subsequently may improv...
