Standing sagittal alignment of the whole axial skeleton with reference to the gravity line in humans.

Human beings stand upright with the chain of balance beginning at the feet, progressing to the lower limbs (ankles, knees, hip joints, pelvis), each of the spinal segments, and then ending at the cranium to achieve horizontal gaze and balance using minimum muscle activity. The details of the alignment and balance of the chain, however, are not clearly understood, due to the lack of information regarding the three-dimensional (3D) orientation of all bony elements in relation to the gravity line (GL). We performed a clinical study to clarify the standing sagittal alignment of whole axial skeletons in reference to the GL using the EOS slot-scanning 3D X-ray imaging system with simultaneous force plate measurement in a healthy human population.

Normative values of spino-pelvic sagittal alignment, balance, age, and health-related quality of life in a cohort of healthy adult subjects.

Purpose: To elucidate the normative values of whole body sagittal alignment and balance of a healthy population in the standing position; and to clarify the relationship among the alignment, balance, health-related quality of life (HRQOL), and age.

Methods: Healthy Japanese adult volunteers [n = 126, mean age 39.4 years (20-69), M/F = 30/96] with no history of spinal disease were enrolled in a cross-sectional cohort study.

Lumbar degenerative spondylolisthesis is not always unstable: clinicobiomechanical evidence.

Study Design: A clinicobiomechanical study.

Objective: To clarify the clinicobiomechanical characteristics of a segment with lumbar degenerative spondylolisthesis (LDS) using an original intraoperative measurement system.

Summary Of Background Data: Although radiographical evaluation of LDS is extensively performed, the diagnosis of segmental instability remains controversial.

A novel, disposable, screen-printed amperometric biosensor for ketone 3-β-hydroxybutyrate fabricated using a 3-β-hydroxybutyrate dehydrogenase-mesoporous silica conjugate.

A disposable amperometric biosensor for ketone 3-β-hydroxybutyrate (3HB) has been developed successfully. The sensor is based on a screen-printed carbon electrode containing Meldola's Blue (MB) and sensing components containing nicotinamide adenine dinucleotide (NAD(+)) and 3-β-hydroxybutyrate dehydrogenase (3HBDH) immobilized in mesoporous silica (FSM8.0) using an aqueous photo-cross-linkable polymer matrix of polyvinyl alcohol (O-391), and it requires only a small sample volume of 10 μL for the measurement.

Intraoperative Neural Mobility and Postoperative Neurological Recovery in Anterior Cervical Decompression Surgery: Evaluation With Intraoperative Sonography.

Study Design: A study using intraoperative sonography (IOS) was conducted for evaluating neural mobility in anterior cervical decompression surgery.

Objectives: To analyze decompression status and mobility of the spinal cord and the nerve root during anterior cervical decompression and to clarify its relevance to the postoperative neurological recovery.

Summary Of Background Data: Several papers introduced the usefulness of IOS assessments; however, there have been no reports systematically evaluating the neural mobility in anterior cervical decompression surgery.

Amperometric L-lactate biosensor based on screen-printed carbon electrode containing cobalt phthalocyanine, coated with lactate oxidase-mesoporous silica conjugate layer.

A novel amperometric biosensor for the measurement of L-lactate has been developed. The device comprises a screen-printed carbon electrode containing cobalt phthalocyanine (CoPC-SPCE), coated with lactate oxidase (LOD) that is immobilized in mesoporous silica (FSM8.0) using a polymer matrix of denatured polyvinyl alcohol; a Nafion layer on the electrode surface acts as a barrier to interferents.

Amperometric determination of choline with enzyme immobilized in a hybrid mesoporous membrane.

Choline sensor is successfully prepared by using immobilized enzyme, i.e., choline oxidase (ChOx) within a hybrid mesoporous membrane with 12 nm pore diameter (F127M).
