The chemical analyses internal alloys showed bracelet spatula were made quaternary copper–zinc–tin–lead alloy, copper–silver–zinc copper–tin, bronze allo...

Anthropogenic factors seriously affect water quality and adversely affect fish populations. Agricultural run-off accumulates in the Mississippi River and the coastal estuaries. Alligator gar (Atractosteus spatula) inhabits these waters and is impacted by agricultural pollution, petrochemical contaminants and oil spills. These fish are bimodal air breathers, and use a primitive lung as an access...

The middle Brazos River, located in east-central Texas, is a meandering lowland river with many oxbow lakes on its flood plain. Flood dynamics of the Brazos River are aseasonal, and faunal exchange during lateral connections of the main river channel and oxbows is pulse-like and occurs only during floods that may be months or years apart. Patterns of resource use among sympatric gar species (Le...

INTRODUCTION Patients can develop trismus from their head and neck cancer or as a result of treatment. Trismus affects the jaw muscles and makes mouth opening difficult. To potentially combat trismus, patients could undertake proactive jaw stretching exercises prior to, during and after radiotherapy, although currently these are not the standard of care.

BACKGROUND Collection technique is critical in the performance of the Papanicolaou (Pap) smear as an important screening tool for cervical cancer. While superior devices have been established, less effective devices continue to be used for both conventional and liquid-based Pap smears. Our aim is to determine the performance of collection devices currently used in obtaining conventional Pap sme...

In the initial clinical examination of a child with ambiguous genitalia an accurate measurement of the corporeal length is needed. Most often the corporeal length is measured with a ruler from the symphysis pubis to the tip of the glans of a stretched penis. More recently, ultrasound has been successfully used to measure corporeal length. This study aimed to (i) establish normal values for corp...
