    Sole Training® with Stacey Lei Krauss Sole Training is a foot fitness program based on two sequences. The self –massage sequence is restorative and therapeutic; compare it to a yoga class (for your feet). The standing sequence promotes strength, endurance, flexibility and coordination; compare it to a boot-camp workout (for your feet). These exercises work; we’ve been doing them for over a decade. *The Sole Training® video download is available at willPowerMethod.com What is foot fitness? Building muscular strength, endurance, flexibility and neuro-muscular awareness in the feet and ankles. What are the benefits of foot fitness? According to Vibram FiveFingers®, exercising while barefoot, or wearing minimal shoes provide the following benefits: 1. Strengthens Muscles in the Feet and Lower Legs Wearing minimal shoes, or training barefoot will stimulate and strengthen muscles in the feet and lower legs, improving general foot health and reducing the risk of injury. 2. Improves Range of Motion in Ankles, Feet and Toes No longer 'cast' in a traditional, structured shoe, the foot and toes move more naturally. 3. Stimulates Neural Function Important to Balance and Agility When barefoot or wearing minimal shoes, thousands of neurological receptors in the feet send valuable information to the brain, improving balance and agility. 4. Eliminate Heel Lift to Align the Spine and Improve Posture By lowering the heel, your bodyweight becomes evenly distributed across the footbed, promoting proper posture and spinal alignment. 5.

  • A Comparative Study of the Ultrastructure of Microvilli in the Epithelium of Small and Large Intestine of Mice
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PubMed Central A COMPARATIVE STUDY OF THE ULTRASTRUCTURE OF MICROVILLI IN THE EPITHELIUM OF SMALL AND LARGE INTESTINE OF MICE T. M. MUKHERJEE and A. WYNN WILLIAMS From the Electron Microscope Laboratory, the Departlnent of Pathology, the University of Otago Medical School, Dunedin, New Zealand ABSTRACT A comparative analysis of the fine structure of the microvilli on jejunal and colonic epi- thelial cells of the mouse intestine has been made. The microvilli in these two locations demonstrate a remarkably similar fine structure with respect to the thickness of the plasma membrane, the extent of the filament-free zone, and the characteristics of the microfila- ments situated within the microvillous core. Some of the core microfilaments appear to continue across the plasma membrane limiting the tip of the microvillus. The main differ- ence between the microvilli of small intestine and colon is in the extent and organization of the surface coat. In the small intestine, in addition to the commonly observed thin surface "fuzz," occasional areas of the jejunal villus show a more conspicuous surface coat covering the tips of the microvilli. Evidence has been put forward which indicates that the surface coat is an integral part of the epithelial cells. In contrast to the jejunal epithelium, the colonic epithelium is endowed with a thicker surface coat. Variations in the organization of the surface coat at different levels of the colonic crypts have also been noted. The func- tional significance of these variations in the surface coat is discussed.

The following bony prominences can usually be palpated in the living subject (corresponding vertebral levels are given in brackets): •◊◊superior angle of the scapula (T2); •◊◊upper border of the manubrium sterni, the suprasternal notch (T2/3); •◊◊spine of the scapula (T3); •◊◊sternal angle (of Louis) — the transverse ridge at the manubrio-sternal junction (T4/5); •◊◊inferior angle of scapula (T8); •◊◊xiphisternal joint (T9); •◊◊lowest part of costal margin—10th rib (the subcostal line passes through L3). Note from Fig. 1 that the manubrium corresponds to the 3rd and 4th thoracic vertebrae and overlies the aortic arch, and that the sternum corre- sponds to the 5th to 8th vertebrae and neatly overlies the heart. Since the 1st and 12th ribs are difficult to feel, the ribs should be enu- merated from the 2nd costal cartilage, which articulates with the sternum at the angle of Louis. The spinous processes of all the thoracic vertebrae can be palpated in the midline posteriorly, but it should be remembered that the first spinous process that can be felt is that of C7 (the vertebra prominens). The position of the nipple varies considerably in the female, but in the male it usually lies in the 4th intercostal space about 4in (10cm) from the midline.

  • Vivid Dreams/ Problems Sleeping: Nausea/Upset Stomach: Itching/Rash
    Addressing NRT Barriers • Assess the severity of symptoms (Is it tolerable?). • Assess Hx: onset, duration and any troubleshooting that has already taken place. If indicated, get history of these symptoms when not taking these medications. You may also ask how Pt. would normally treat these symptoms. • If symptoms are tolerable àdevelop troubleshooting plan with Pt. Inform Pt. that many symptoms will go away after a few days. Reassess at next visit, but ask Pt. to call if symptoms persist/worsen or become intolerable before next call/visit. • If symptoms are not tolerableàconsider changing products or dosages as applicable. Consult study physician, as needed. Refer Pt. to their personal physician, if needed (e.g., prescription strength creams). • All potential cardiac symptoms should be promptly reported to study physician. Advise Pt. to discontinue NRT when indicated or instructed by study physician. Vivid Dreams/ Problems Sleeping: - Assess if sleep is being disrupted. Is night waking normal for Pt. – what is Pts.’ normal routine? - May try taking patch off at night, keeping in mind cravings may be stronger in the AM. After a couple of nights, try again to wear patch overnight. If using more than 1 patch, may consider only wearing 1 at night. - May try removing patch at night and putting on 2 hours before waking, especially when early morning waking is part of routine. Otherwise, can set an alarm, put on patch, and go back to sleep. - Regulate eating and sleeping patterns and use sleep hygiene tips (relaxation training, avoid caffeine). - Do not smoke or use short-acting NRT within 1-2 hours of bedtime (especially if sleep initiation is the major complaint.) Nausea/upset stomach: - Ask if nausea is only after using gum/lozenge or also after smoking a cigarette.

  • Rethinking the Evolution of the Human Foot: Insights from Experimental Research Nicholas B
    © 2018. Published by The Company of Biologists Ltd | Journal of Experimental Biology (2018) 221, jeb174425. doi:10.1242/jeb.174425 REVIEW Rethinking the evolution of the human foot: insights from experimental research Nicholas B. Holowka* and Daniel E. Lieberman* ABSTRACT presumably owing to their lack of arches and mobile midfoot joints Adaptive explanations for modern human foot anatomy have long for enhanced prehensility in arboreal locomotion (see Glossary; fascinated evolutionary biologists because of the dramatic differences Fig. 1B) (DeSilva, 2010; Elftman and Manter, 1935a). Other studies between our feet and those of our closest living relatives, the great have documented how great apes use their long toes, opposable apes. Morphological features, including hallucal opposability, toe halluces and mobile ankles for grasping arboreal supports (DeSilva, length and the longitudinal arch, have traditionally been used to 2009; Holowka et al., 2017a; Morton, 1924). These observations dichotomize human and great ape feet as being adapted for bipedal underlie what has become a consensus model of human foot walking and arboreal locomotion, respectively. However, recent evolution: that selection for bipedal walking came at the expense of biomechanical models of human foot function and experimental arboreal locomotor capabilities, resulting in a dichotomy between investigations of great ape locomotion have undermined this simple human and great ape foot anatomy and function. According to this dichotomy. Here, we review this research, focusing on the way of thinking, anatomical features of the foot characteristic of biomechanics of foot strike, push-off and elastic energy storage in great apes are assumed to represent adaptations for arboreal the foot, and show that humans and great apes share some behavior, and those unique to humans are assumed to be related underappreciated, surprising similarities in foot function, such as to bipedal walking.

  • Coprolites of Deinosuchus and Other Crocodylians from the Upper Cretaceous of Western Georgia, Usa
    Milàn, J., Lucas, S.G., Lockley, M.G. and Spielmann, J.A., eds., 2010, Crocodyle tracks and traces. New Mexico Museum of Natural History and Science, Bulletin 51. 209 COPROLITES OF DEINOSUCHUS AND OTHER CROCODYLIANS FROM THE UPPER CRETACEOUS OF WESTERN GEORGIA, USA SAMANTHA D. HARRELL AND DAVID R. SCHWIMMER Department of Earth and Space Sciences, Columbus State University, Columbus, GA 31907 USA, [email protected] Abstract—Associated with abundant bones, teeth and osteoderms of the giant eusuchian Deinosuchus rugosus are larger concretionary masses of consistent form and composition. It is proposed that these are crocodylian coprolites, and further, based on their size and abundance, that these are coprolites of Deinosuchus. The associated coprolite assemblage also contains additional types that may come from smaller crocodylians, most likely species of the riverine/estuarine genus Borealosuchus, which is represented by bones, osteoderms and teeth in fossil collections from the same site. INTRODUCTION The Upper Cretaceous Blufftown Formation in western Georgia contains a diverse perimarine and marine vertebrate fauna, including many sharks and bony fish (Case and Schwimmer, 1988), mosasaurs, plesio- saurs, turtles (Schwimmer, 1986), dinosaurs (Schwimmer et al., 1993), and of particular interest here, abundant remains of the giant eusuchian crocodylian Deinosuchus rugosus (Schwimmer and Williams, 1996; Schwimmer, 2002). Together with bite traces attributable to Deinosuchus (see Schwimmer, this volume), there are more than 60 coprolites recov- ered from the same formation, including ~30 specimens that appear to be of crocodylian origin. It is proposed here that the larger coprolites are from Deinosuchus, principally because that is the most common large tetrapod in the vertebrate bone assemblage from the same locality, and it is assumed that feces scale to the producer (Chin, 2002).
