At least 13 times during the Pleistocene Epoch lava flowed into the inner gorge of the Grand Canyon and formed lava dams, as high as 600 m, that temporarily blocked the flow of the Colorado River. K-Ar ages on these lava dams indicate that the seven youngest formed within a short period of time between about 0.6 and 0.4 mega-annum (Ma). The physiography of the lava dam remnants within the canyo...

While most large river-deltas in the world are facing the risk of subsidence and erosion in the Anthropocene, it is suspected that the Changjiang submerged delta (CSD) could be subjected to the impacts of the world's largest dam, the Three Gorges Dam (TGD). Here we firstly indicate that the CSD went through high accumulation (1958-1978); slight accumulation (1978-1997), slight erosion (1997-200...

UNLABELLED We present a review of all the cases of free toe pulp transfer and an algorithm for application of free pulp transfer in complicated Allen fingertip defect. METHODS Seventeen patients underwent free toe pulp transfer for fingertip reconstruction by the senior author. Twelve cases were Allen type II with oblique pulp defect, 4 were Allen type III, and 1 patient had 2 fingertip injur...

Ontogenetic evidence suggests a possible link between second toe length and prenatal androgenization, and therefore it is possible that a longer second toe is related to behaviors and traits previously shown to be associated with testosterone. In an exploratory analysis of this phenomenon, respondents provided self-reports of various behaviors and traits previously shown to be related to testos...

Perioperative transoesophageal echocardiography (TOE) was introduced from cardiology into cardiac anaesthesia in the 1980s. Initially TOE was used mainly as a monitor of left ventricular ischaemia, but now provides real-time dynamic information about the anatomy and physiology of the whole heart. TOE is of value in the management of patients undergoing procedures including cardiac valvular repa...

[Purpose] This study assessed the relationships between peak toe flexor muscle strength, ankle dorsiflexion range of motion, and countermovement jump height. [Subjects and Methods] Eighteen healthy volunteers participated in the study. Each participant completed tests for peak toe flexor muscle strength, ankle dorsiflexion range of motion, and countermovement jump height. [Results] The results ...

Idiopathic toe-walking is defined as persistent toe-walking in a normal child in the absence of developmental, neurological or neuromuscular conditions. True idiopathic toe-walking is a rare referral, representing approximately 1:100 new patients seen in the Paediatric Orthopaedic Clinic. A prospective study of idiopathic toe-walking (ITW) was organised between 1999 and 2003. Patients underwent...

OBJECTIVES Use of a rubber dam during root canal treatment is considered the standard of care because it enhances patient safety and optimises the odds of successful treatment. Nonetheless, not all dentists use a rubber dam, creating disconnect between presumed standard of care and what is actually done in clinical practice. Little is known about dentists' attitudes towards use of the rubber da...

Received: 01.07.2014; Accepted: 09.07.2015 Fig. 1: Left side striatal toe A 21 year old male who was taking antipsychotic drugs from past 3 years presented with expressionless face, slow initiation of movement and abnormal upward posturing of the left big toe for 6 months.
