Christine Dierickx
OBJECTIVE: The picosecond 755 nm alexandrite laser using a diffractive lens array has demonstrated consistent clinical efficacy for improving the appearance of acne scarring and wrinkles amongst other benefits. This small pilot study is to assess the difference, if any, in clinical benefit if a higher than the standard protocol for number of pulses delivered to a tissue area is used compared to the standard protocol guidelines. METHOD: Seven subjects received treatment to one side of the face with a standard protocol number of laser pulses with the other side of the face receiving higher than standard number of pulses from the same 755 nm picosecond laser using an additional diffractive lens array...

The regions of Al‑Qatif and Al‑Ahssa in the Eastern Province of Saudi Arabia are known for their high prevalence of hemoglobinopathies, including β‑thalassemia and sickle cell anemia. Previously, the α‑gene deletion has been demonstrated as highly prevalent among populations residing in these two regions. The present study was conducted in order to investigate the implications of the α‑globin gene deletion on fetal hemoglobin (HbF) and hemoglobin α2 (HbA2) concentrations in patients with transfusion‑dependent β‑thalassemia...

BACKGROUND: Infraorbital dark circles result from a combination of factors. The fractionated picosecond 755 nm alexandrite laser and dual wavelength picosecond Nd:YAG laser have not been examined as a method of addressing infraorbital hyperpigmentation. OBJECTIVE: To determine the efficacy and safety of treatment of infraorbital dark circles using fractionated picosecond 755 nm and dual wavelength picosecond Nd:YAG laser. METHODS AND MATERIALS: These trials did not utilize a comparative design; rather, these were separate, prospective, open-label, evaluator-blinded trials utilizing two treatment regimens: (i) 19 adult subjects were treated in a single session with the dual wavelengths of 532 nm and 1,064 nm in consecutive passes using the fractionated lens; (ii) 10 adult subjects were treated using the picosecond 755 nm laser via the fractionated lens in three treatment sessions at 3 week intervals...

PURPOSE: (13) C magnetic resonance spectroscopy (MRS) in combination with infusion of (13) C-labeled substrates has led to unique insights into human brain metabolism and neurotransmitter cycling. However, the low sensitivity of direct (13) C MRS and high radiofrequency power requirements has limited (13) C MRS studies to predominantly data acquisition in large volumes of the occipital cortex. The purpose of this study is to develop an MRS technique for localized detection of (13) C-labeling of glutamate and glutamine in the human frontal lobe...

PURPOSE: Renal dynamic contrast-enhanced (DCE) MRI provides information on renal perfusion and filtration. However, clinical implementation is hampered by challenges in postprocessing as a result of misalignment of the kidneys due to respiration. We propose to perform automated image registration using the fat-only images derived from a modified Dixon reconstruction of a dual-echo acquisition because these provide consistent contrast over the dynamic series. METHODS: DCE data of 10 hypertensive patients was used...

BACKGROUND: Hungary has been serious facing human resources crisis in health care, as a result of a massive emigration of health workers. The resulting shortage is unevenly distributed among medical specialisations. The findings of research studies are consistent in that the most important motivating factor of the choice of the medical career and of medical specialisations is professional interest. Beyond this, it is important to examine other reasons of why students do or do not choose certain specialisations...

OBJECTIVE: Nevus of Ota represents congenital dermal melanocytosis in a trigeminal distribution, most commonly occurring in Asian individuals and other individuals with skin of color. Evidence suggests early treatment is beneficial. Multiple reports have shown efficacy and safety of Q-switched laser treatment in adults. There is little data on children and in non-Asian skin types. This series was done to demonstrate safe and effective use of Q-switched laser therapy in children of multiple skin types...

PURPOSE: The average energy expended by an energetic electron to create an ion pair in dry air, Wair, is a key quantity in radiation dosimetry. Although Wair is well established for electron energies up to about 3 MeV there is limited data for higher energies. The measurements by Domen and Lamperti [Med. Phys. 3, 294{301 (1976)] using electron beams in the energy range from 15 to 50 MeV can, in principle, be used to deduce values for Wair, if the electron stopping power of graphite and air are known...

The objective of this study was to examine the relationship between mitochondrial proton leak and feed efficiency with supplementation of different levels of Cu, Mn and Zn (Bioplex, Alltech) at levels above Nutrient Requirements of Dairy Cattle (NRC, 2001). Milk yield and composition, mineral excretion in milk and faeces, feed efficiency and liver mitochondrial proton leak were measured in 60 Holstein dairy cows at approximately 70 days in milk on a commercial dairy. Treatments reflect total Cu, Mn and Zn intake/day and are as follows: (i) High: 444 mg/day Cu, 3492 mg/day Mn, 2234 mg/day Zn; (ii) Med: 436 mg/day Cu, 3002 mg/day Mn, 2047 mg/day Zn; (iii) Low: 420 mg/day Cu, 2764 mg/day Mn, 2186 mg/day Zn; (iv) LowMn: 391 mg/day Cu, 2617 mg/day Mn, 1849 mg/day Zn; and (v) Control: 264 mg/day Cu, 2850 mg/day Mn, 1593 mg/day Zn...

Véronique Fortier, Ives R Levesque
PURPOSE: Phase processing impacts the accuracy of quantitative susceptibility mapping (QSM). Techniques for phase unwrapping and background removal have been proposed and demonstrated mostly in brain. In this work, phase processing was evaluated in the context of large susceptibility variations (Δχ) and negligible signal, in particular for susceptibility estimation using the iterative phase replacement (IPR) algorithm. METHODS: Continuous Laplacian, region-growing, and quality-guided unwrapping were evaluated...

Michael Loecher, Daniel B Ennis
PURPOSE: To introduce and demonstrate a nonconvex optimization method for reconstructing velocity data from low-velocity-encoding (Venc ) phase-contrast MRI data. THEORY AND METHODS: Solving for velocity values from phase-contrast MRI data was formulated as a nonconvex optimization problem. Weighting was added to account for intravoxel dephasing, and a Laplacian-based regularization was used to account for residual velocity aliasing. The reconstruction was tested with two low-Venc schemes: dual-Venc and a multidirectional high-moment encoding...

PURPOSE: Estimation of brain metabolite concentrations by MR spectroscopic imaging (MRSI) is complicated by partial volume contributions from different tissues. This study evaluates a method for increasing tissue specificity that incorporates prior knowledge of tissue distributions. METHODS: A spectral decomposition (sDec) technique was evaluated for separation of spectra from white matter (WM) and gray matter (GM), and for measurements in small brain regions using whole-brain MRSI...

BACKGROUND: Aging is an important determinant of the rate of atherosclerosis development, mainly through low-grade inflammation. Diet, and particularly its fat content, modulates the inflammatory response in fasting and postprandial states. OBJECTIVE: We aimed to study the effects of dietary fat on endotoxemia in healthy older adults. MATERIALS AND METHODS: Twenty healthy older adults were randomized to three diets, lasting three-weeks each, using a crossover design: 1...
