Hemodynamics of the CL and each main uterine artery during expansion of the allantochorion from the ipsilateral side (CL side) to the contralateral side were studied in heifers (n = 8 nonbred, 9 pregnant). Progesterone concentration, vascular perfusion index for each uterine artery (by spectral ultrasonography), extent of blood flow in the CL (percentage of CL tissue with color-Doppler signals of blood flow), and intrauterine location of the expanding allantochorion (by gray-scale ultrasonic imaging) were determined daily from Days 14-60 (Day 0 = ovulation)...

The field of microfluidics holds great promise for the development of simple and portable lab-on-a-chip systems. The use of capillarity as a means of fluidic manipulation in lab-on-a-chip systems can potentially reduce the complexity of the instrumentation and allow the development of user-friendly devices for point-of-need analyses. In this work, a PDMS microchannel-based, colorimetric, autonomous capillary chip provides a multiplexed and semi-quantitative immunodetection assay. Results are acquired using a standard smartphone camera and analyzed with a simple gray scale quantification procedure...

OBJECTIVES: The purpose was to analyze the agreement and binary accuracy of the degree of internal carotid artery stenosis (ICAS) as determined by 4-dimensionally (4D) real-time gray-scale guided 3-dimensional (3D) color-Doppler ultrasonography (3DC-US) (4D/3DC-US) compared with catheter angiography (CA) and duplex ultrasonography (DUS). This study hypothesized that 4D/3DC-US is noninferior to CA and DUS in grading ICAS in selected patients. BACKGROUND: Clinical stratification in patients with ICAS largely depends on a patient's symptomatic status and the degree of stenosis...

Although there is much evidence for a role of GABAB receptors in the pathophysiology of anxiety, the underlying neuronal mechanisms are largely unclear. The GABAB receptor allosteric positive modulator, GS39783, exerts anxiolytic effects without interfering with GABAB-mediated modulation of body temperature, cognitive performance and locomotor activity thus offering advantages over GABAB receptor agonists. However, the precise neural circuits underlying the anxiolytic effects of GS39783 are unknown. The aim of the present study was to identify brain structures and associated neuronal circuits that are modulated by GS39783 under either basal or mild stress conditions...

Sexting among youths has become a necessary topic of interest in research because of the negative consequences that this activity could create, especially when content is shared with others. Indeed, this loss of control could lead to humiliation, (cyber)bullying, or harassment. The development of new technologies, press coverage, and increase of prevalence rates could also explain the growth of interest in sexting. However, its definition is still a gray area. This review examines the different definitions of sexting used in the literature and its correlates...

Children and adolescents living with human immunodeficiency virus (HIV) represent a population that requires a unique approach to HIV care. Prevention, testing, initiation of antiretroviral therapy (ART), and retention and engagement in care are critical steps. Each step requires providers to address age-specific barriers, so that successful and prolonged viral suppression can occur. Adherence to ART, disclosure of HIV-positive status, and stigma are examples of struggles faced by youth, their families, and health care providers...

Fetal alcohol spectrum disorders (FASD) are characterized by impairment in cognitive function that may or may not be accompanied by craniofacial anomalies, microcephaly, and/or growth retardation. Resting-state functional MRI (rs-fMRI), which examines the low-frequency component of the blood oxygen level dependent (BOLD) signal in the absence of an explicit task, provides an efficient and powerful mechanism for studying functional brain networks even in low-functioning and young subjects. Studies using independent component analysis (ICA) have identified a set of resting-state networks (RSNs) that have been linked to distinct domains of cognitive and perceptual function, which are believed to reflect the intrinsic functional architecture of the brain...

PURPOSE: To investigate the ability of three-dimensional (3D) MRI placental shape and textural features to predict fetal growth restriction (FGR) and birth weight (BW) for both healthy and FGR fetuses. MATERIALS AND METHODS: We recruited two groups of pregnant volunteers between 18 and 39 weeks of gestation; 46 healthy subjects and 34 FGR. Both groups underwent fetal MR imaging on a 1.5 Tesla GE scanner using an eight-channel receiver coil. We acquired T2-weighted images on either the coronal or the axial plane to obtain MR volumes with a slice thickness of either 4 or 8 mm covering the full placenta...

BACKGROUND: Migraine constitute a disorder characterized by recurrent headaches, and have a high prevalence, a high socio-economic burden and severe effects on quality of life. Our previous fMRI study demonstrated that some brain regions are functional alterations in migraineurs. As the function of the human brain is related to its structure, we further investigated white and gray matter structural alterations in migraineurs. METHODS: In current study, we used surface-based morphometry, voxel-based morphometry and diffusion tensor imaging analyses to detect structural alterations of the white matter and gray matter in 32 migraineurs without aura compared with 32 age- and gender-matched healthy controls...

Inversion recovery ultrashort echo time (IR-UTE) imaging holds the potential to directly characterize MR signals from ultrashort T2 tissue components (STCs), such as collagen in cartilage and myelin in brain. The application of IR-UTE for myelin imaging has been challenging because of the high water content in brain and the possibility that the ultrashort T2 * signals are contaminated by water protons, including those associated with myelin sheaths. This study investigated such a possibility in an ovine brain D2 O exchange model and explored the potential of IR-UTE imaging for the quantification of ultrashort T2 * signals in both white and gray matter at 3 T...

BACKGROUND: Tofu from aged soybeans has poor quality, mainly texture. Texture defects related in literature are contradictory. No study has approached all sensory properties simultaneously. The objective of this study was to evaluate the effect of soybean aging conditions (natural: ambient temperature and RH, 18 months, and accelerated: 30 °C, 84% RH, 6 months) on all the sensory characteristics and acceptance of tofu. Texture and color were also evaluated by instrumental method. Control condition was -20 °C, 47% RH...

OBJECTIVE Spine stereotactic radiosurgery (SRS) is a safe and effective treatment for spinal metastases. However, it is unknown whether this highly conformal radiation technique is suitable at instrumented sites given the potential for microscopic disease seeding. The authors hypothesized that spinal decompression with instrumentation is not associated with increased local failure (LF) following SRS. METHODS A 2:1 propensity-matched retrospective cohort study of patients undergoing SRS for spinal metastasis was conducted...

Sebaceoma associated with seborrheic keratosis has only been described once in the literature. Herein, we present an additional case in a 69-year-old woman who complained of a multicolored plaque on the left breast. Dermatoscopy showed a central orange lesion with orange globules suggestive of dilated glands. The periphery of the lesion was brown and gray, with some more pigmented zones. The histopathological study demonstrated a seborrheic keratosis in the peripheral areas, whereas the central part of the lesion was a sebaceoma...
