Wedge prism approach for simultaneous multichannel microscopy.

Multichannel (multicolor) imaging has become a powerful technique in biology research for performing in vivo neuronal calcium imaging, colocalization of fluorescent labels, non-invasive pH measurement, and other procedures. We describe a novel add-on approach for simultaneous multichannel optical microscopy based on simple wedge prisms. Our device requires no alignment and is simple, robust, user-friendly, and less expensive than current commercial instruments based on switchable filters or dual-view strategies.

Methods: Antidromic sensory nerve conduction studies of the ulnar nerve using surface electrodes were performed on 100 volunteers. Reference values were computed from optimally transformed data.

A regional interdependence model of musculoskeletal dysfunction: research, mechanisms, and clinical implications.

The term 'regional interdependence' or RI has recently been introduced into the vernacular of physical therapy and rehabilitation literature as a clinical model of musculoskeletal assessment and intervention. The underlying premise of this model is that seemingly unrelated impairments in remote anatomical regions of the body may contribute to and be associated with a patient's primary report of symptoms. The clinical implication of this premise is that interventions directed at one region of the body will often have effects at remote and seeming unrelated areas.

Psychometric properties of selected tests in patients with lumbar spinal stenosis.

Background Context: The psychometric properties of many outcome tools commonly used with patients with lumbar spinal stenosis have yet to be examined.

Purpose: Examine the test-retest reliability, responsiveness, and minimum levels of detectable and clinically important differences for several outcome measures in a cohort of patients with lumbar spinal stenosis.

Study Design/setting: Cohort secondary analysis of a randomized clinical trial of patients with lumbar spinal stenosis receiving outpatient physical therapy.

Primary care referral of patients with low back pain to physical therapy: impact on future health care utilization and costs.

Study Design: A retrospective cohort.

Objective: To describe physical therapy utilization following primary care consultation for low back pain (LBP) and evaluate associations between the timing and content of physical therapy and subsequent health care utilization and costs.

Summary Of Background Data: Primary care management of LBP is highly variable and the implications for subsequent costs are not well understood.

Spark-induced breakdown spectroscopy and multivariate analysis applied to the measurement of total carbon in soil.

Identifying and implementing techniques for carbon management has become an important endeavor in the mitigation of global climate change. Two important techniques being pursued are geologic and terrestrial carbon sequestration. With regard to terrestrial sequestration, in order to accurately monitor changes in soil carbon potentially induced by sequestration practices, rapid, cost-effective, and accurate measurements must be developed.

Comparison of short-term response to two spinal manipulation techniques for patients with low back pain in a military beneficiary population.

Objective: To determine whether military health care beneficiaries with low back pain (LBP) who are likely to respond successfully to spinal manipulation experience a difference in short-term clinical outcomes based on the manipulation technique that is used.

Methods: Sixty patients with LBP identified as likely responders to manipulation underwent a standardized clinical examination and were randomized to receive a lumbopelvic (LP) or lumbar neutral gap (NG) manipulation technique. Outcome measures were a numeric pain rating scale and the modified Oswestry Disability Questionnaire.

Neck pain: Clinical practice guidelines linked to the International Classification of Functioning, Disability, and Health from the Orthopedic Section of the American Physical Therapy Association.

The Orthopaedic Section of the American Physical Therapy Association presents this second set of clinical practice guidelines on neck pain, linked to the International Classification of Functioning, Disability, and Health (ICF). The purpose of these practice guidelines is to describe evidence-based orthopaedic physical therapy clinical practice and provide recommendations for (1) examination and diagnostic classification based on body functions and body structures, activity limitations, and participation restrictions, (2) prognosis, (3) interventions provided by physical therapists, and (4) assessment of outcome for common musculoskeletal disorders.

The short-term effects of thoracic spine thrust manipulation on patients with shoulder impingement syndrome.

The study was an exploratory, one group pretest/post-test study, with the objective of investigating the short-term effects of thoracic spine thrust manipulations (TSTMs) on patients with shoulder impingement syndrome (SIS). There is evidence that manual physical therapy that includes TSTM and non-thrust manipulation and exercise is effective for the treatment of patients with SIS. However, the relative contributions of specific manual therapy interventions are not known.

Detection and measurement of middle-distillate fuel vapors by use of tunable diode lasers.

A sensor for the rapid (10-ms response time) measurement of vapors from the hydrocarbon-based fuels JP-8, DF-2, and gasoline is described. The sensor is based on a previously reported laser-mixing technique that uses two tunable diode lasers emitting in the near-infrared spectral region [Appl. Opt.

High-sensitivity laser absorption measurements of broadband absorbers in the near-infrared spectral region.

We describe the development and characterization of a near-infrared diode-laser-based sensor to measure the vapor from trace gases having unstructured absorption spectra. The technique uses two equal amplitude-modulated laser beams, with the modulation of the two lasers differing in phase by 180 deg. One of the laser beams is at a wavelength absorbed by the gas [for these experiments, vapor is from pyridine (C(5)H(5)N)], and the second laser beam is at a wavelength at which no absorption occurs.

Soot-velocity measurements by particle vaporization velocimetry.

We demonstrate a new imaging technique for velocity measurements in particle-laden flows. The technique, particle vaporization velocimetry, is a form of flow tagging based on laser vaporization of absorbing particles at defined locations in the flow. The locations of these tagged regions are then interrogated after a known delay to determine the convective velocity.
