This study examined the incidence of high peak plantar pressure and plantar callus in 211 adolescents with diabetes mellitus and 57 nondiabetic controls. The percentage of subjects with these anomalies was the same in both groups. Although diabetic subjects were no more likely than nondiabetic controls to have high peak plantar pressure and callus, these anomalies place individuals with diabetes at greater risk of future foot problems. The effects of orthoses, cushioning, and both in combination were monitored in 17 diabetic subjects with high peak plantar pressure and in 17 diabetic subjects

BACKGROUND: Post-operative non-articular tibia fracture several problems that can occur include; pain, muscles atrophy, muscles weakness, joint stiffness, delayed union, and non-union that makes patients limited in their daily activities.

Markers of osteoblast activity are bone-specific alkaline phosphatase (BSAP) levels and Hummer scale callus formation. Not yet known the effect isometric exercise of plantar fle

Callus has been identified as a risk factor leading to severe diabetic foot ulcer; thus, it is necessary to prevent its formation. Callus formation under the first, second, and fifth metatarsal heads (MTHs) is associated with external forces (pressure and shear stress) during walking. However, the gait factors increasing the external forces remain undetermined. Thus, this study aims to identify the factors increasing the external forces to prevent callus formation.

Introduction & Objectives: Metatarsal Bone fractures contribute 3-7% of all fractures of the body, 35% of all fractures from the foot and also contribute 75 new cases per 10.000 persons per year. Another study evaluated the incidence involvement of multiple metatarsal fractures is higher than isolated metatarsal fractures. Metatarsal bone fractures mostly caused by low energy trauma, and also high energy trauma makes the incidence higher. The previous study said, that 43% of metatarsal fractures are the neck of the second and third metatarsal bones. Intramedullary fixation using Kirschner

 Mammillaria plumosa es una cactácea mexicana altamente apreciada como planta ornamental por su peculiar morfología. La extracción desmedida y el saqueo de sus poblaciones silvestres han forzado su protección y actualmente se encuentra clasificada como una especie en peligro de extinción. Ante esta crítica situación el presente trabajo se planteó como objetivo desarrollar un sistema de propagación in vitro eficiente factible de implementarse como una de las estrategias para la recuperación de la especie.

ABSTRACT - The development of protocols to overcome the current limitations of callus induction and in vitro regeneration of highly recalcitrant tropical maize is crucial for plant genetic transformation. The ability of embryogenic callus (EC) formation of 46 tropical maize hybrids and 14 inbred lines was tested using N6 medium with the following changes: medium A (N6 + 15 μM dicamba + 25 mM L-proline + 88 mM AgNO3), medium B (N6 + 30 μM dicamba + 25 mM L-proline + 88 mM AgNO3), medium C (N6+ 30 μM dicamba + 6 mM L-proline), and medium D (N6+ 30 μM dicamba + 25 mM L-proline).
