Biological effects of low power nonionizing radiation: A narrative review

Biswadev Roy, Suryakant Niture, Marvin H. Wu

Background and controlled electromagnetic radiation (EMR) on cells and tissues induces thermal, non-thermal, and dielectric property change. After EMR interaction with cells/tissues the resulting signal is used for imaging, bio-molecular response, and photo-biomodulation studies at infrared regime, and therapeutic use. We attempt to present a review of current literature with a focus to present compilation of published experimental results for each regime viz. microwave (extremely low frequency, ELF to 3 GHz), to cellular communication frequencies (100 kHz to 300 GHz), millimeter wave (300 GHz-1 THz), THz (1 THz-20THz) and the infra-red band extending up to 461 THz.

Radiation induced radicular hypoplasia: A rare case report

Mohd Saalim, Kaustubh Sansare, Freny R. Karjodkar, Bushra Rahman, Ibrahim K Ali, Huma Parveen

Irradiation is considered as one of the causes that may inhibit tooth development. Radiation exposure during the period of tooth development may result in impaired, delayed, or absolute failure to develop/eruption of the tooth. Radiation exposure at high dosage may also impair facial development in the pediatric population who had received radiation therapy for a malignant tumor in the head and neck region. Here we reported a case of Radiation-Induced Radicular Hypoplasia (RIRH) in a 19-year-old patient who received radiotherapy ten years ago for the Embryonal Rhabdo Myo Sarcoma of the soft palate.

Modification of circumsolar radiation for anisotropic diffuse radiation models: Photovoltaic collectors on sloped planes

Appelbaum J, Aronescu A

Photovoltaic fields are deployed in multiple collector rows on horizontal and on sloped planes, therefore the second (and subsequent rows) sees the sky dome with a smaller angle than the first (front) row. A relatively large number of diffuse radiation models have been proposed based on isotropic and anisotropic models. The anisotropic models include circumsolar radiation and horizon brightening, and refer to single rows of collectors. The present article modifies the anisotropic models by two factors: (a) Sky view factor of a second row, depending on the collector and field parameters, (b) Modification to circumsolar brightening.

Comparison of T1 FLAIR BLADE with and without parallel imaging against T1 turbo spin echo in the MR imaging of lumbar spine in the sagittal plane

Spinal cord and nerves are best visualized by MRI, which is able to show structural and functional anomalies of the spine. The primary objective of this study is to identify advantages or disadvantages of the T1-weighted fluid attenuated inversion recovery (FLAIR) sequence with BLADE technique (T1W-FLAIR BLADE), with and without parallel imaging when compared with T1 Turbo Spin Echo (T1 TSE) sequence when performing MRI examination of the lumbar spine in a sagittal view. L-spine examinations with T1W-FLAIR BLADE (with and without parallel imaging) and T1 TSE were acquired on 44 patients using a 1.5T scanner. These sequences were assessed by two radiologists a) quantitatively by comparing the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and relative contrast (ReCon) measurements and b) qualitatively based on different features of the images such as cerebrospinal fluid (CSF) nulling.

Occurrence of cervical spine arthritis highly responsive to adalimumab in a patient with psoriatic peripheral arthritis and longstanding remission while on etanercept therapy

Cervical spine involvement frequently occurs in patients with Psoriatic Arthritis (PsA) even in absence of sacroiliitis. Long disease duration, high disease activity in the first five years and presence of peripheral involvement are all predictors of this peculiar articular involvement.

Stroke is the 5th leading cause of death and the leading cause of long-term disability in the United States. Every 40 seconds, someone in the United States sustains a stroke, resulting in approximately 133,000 deaths per year.

Hypothermic neuroprotection following neonatal hypoxic-ischemic encephalopathy: medico-legal implications

Hypoxic-ischemic encephalopathy (HIE) continues to be an important cause of long-term neurologic disability among newborn infants. The estimated incidence ranges from 2-3/1000 live births in developed countries, to as high as 10-20/1000 in developing countries [1]. Affected infants who survive are at a 25% risk for cerebral palsy, epilepsy, and cognitive deficits and may require lifelong medical care.
