Sexual reproduction is essential for the life cycle of most angiosperms. However, pseudovivipary is an important reproductive strategy in some grasses. In this mode of reproduction, asexual propagules are produced in place of sexual reproductive structures. However, the molecular mechanism of pseudovivipary still remains a mystery. In this work, we found three naturally occurring mutants in ric...

Anhydrous ferrous (II) oxalate (AFO) outperforms its hydrated form when used as an anode material in Li-ion batteries (LIBs). With the increasing interest Na-ion (NIBs) mind, we examine potential of AFO NIBs through first principles calculations involving both periodic and non-periodic structures. Our analysis based on (non-periodic) modeling scheme shows that generates a low reaction 1.22 V (1...

Accurate alignment of anatomical and mechanical joint axes is one of the major biomechanical principles pertaining to articulated orthoses, yet knowledge of the potential effects of axis misalignment is limited. The purpose of this project was to model the effects of systematic linear (proximal-distal and anterior-posterior) misalignments of single axis mechanical ankle joints in an ankle-foot ...

OBJECTIVE To assess the tolerability and efficacy of a commercially available footdrop neuroprosthesis for treatment of footdrop in children with hemiparetic cerebral palsy. DESIGN A prospective, observational pilot study. SETTING Marshfield Clinic, Department of Physical Medicine. PARTICIPANTS Ten children, ages 7-12 years, with hemiparetic cerebral palsy, who use an ankle foot orthosis ...

The ameloblastic fibro-odontoma (AFO) is a rare odontogenic tumor that occurs predominantly in children and is generally associated with unerupted teeth. The choice of treatment for this entity is conservative surgery with enucleation and its prognosis is excellent. However, preserving the associated impacted teeth may make complete removal of the lesion difficult and may explain some cases of ...

Robotic technologies are being employed increasingly in the treatment of lower limb disabilities. Individuals suffering from stroke and other neurological disorders often experience inadequate dorsiflexion during swing phase of the gait cycle due to dorsiflexor muscle weakness. This type of pathological gait, mostly known as drop-foot gait, has two major complications, foot-slap during loading ...

Botulinum toxin injections may significantly improve lower limb kinematics in gait of children with spastic forms of cerebral palsy. Here we aimed to analyze the effect of lower limb botulinum toxin injections on trunk postural control and lower limb intralimb (intersegmental) coordination in children with spastic diplegia or spastic hemiplegia (GMFCS I or II). We recorded tridimensional trunk ...

Eighteen children with hemiplegia, mean age 8 years 5 months, underwent gait analysis and musculoskeletal modelling using specially designed software. The maximum lengths of the hamstrings were determined for each child walking in and out of an ankle-foot orthosis (AFO). The muscles were deemed to be short if shorter than the normal average -1SD. In bare feet 8 participants had short medial ham...

PURPOSE Children with cancer are at risk for physical performance limitations. In this pilot study we investigated the feasibility and initial efficacy of an ankle foot orthosis (AFO) in children with non-central nervous system cancer with peripheral weakness. METHODS Participants included children aged 5 to 11 years diagnosed with cancer. Children wore AFOs for 1 cycle of chemotherapy. Pre- ...
