The structural and magnetic properties of the Y1-xTbxMnO3(0.1x0.3)compoundswere investigated.Neutron diffraction patterns for all three samples,recorded at room temperature (RT),were fitted to the nuclear structure confirming the paramagnetic nature of the compounds. At 2.8 K,for the x = 0.1 sample magnetic moments of the Tb3+ionic as well as Mn3+ionic were ordered.At 5 K for the x = 0.2 sample only the Mn3+ionic magnetic moments were ordered. Therewere six sites for Mn atoms. Three on the z = 0 plane and three on the z = 0...

An animal model that allows for assessment of the degree of stretching or contraction of the implant area and the in vivo degradation properties of biological meshes is required to evaluate their performance in vivo. Adult New Zealand rabbits underwent full thickness subtotal unilateral rectus abdominis muscle excision and were reconstructed with the non-biodegradable Peri-Guard(®), Prolene(®) or biodegradable Surgisis(®) meshes. Following 8 weeks of recovery, the anterior abdominal wall tissue samples were collected for measurement of the implant dimensions...

The aim of this study was to evaluate the effects of in vivo and in vitro treatments with selective estrogen receptor modulator (SERM), tamoxifen on testicular functions. The testis treated with tamoxifen, in vivo or in vitro, showed dose-dependent regressive changes in spermatogenesis. This study showed that the decreased estrogenic effect due to tamoxifen may be directly responsible for decreased testicular expression of aromatase, which in turn may be responsible for decreased synthesis of estradiol in the testis...

This paper proposes a novel pre-processing method based on combining bandpass with Savitzky-Golay filtering to further improve the prediction performance of the linear calibration models Principal Component Regression (PCR) and Partial Least Squares Regression (PLSR) in near infrared spectroscopy. The proposed method is compared to the highly efficient RReliefF pre-processing technique for further evaluation. The developed calibration models have been validated to predict the glucose concentration from near infrared spectra of a mixture of glucose and human serum albumin in a phosphate buffer solution...

Sleep apneas are the most common type of sleep-related breathing disorders which cause a patient to move from a good sleep into an inefficient sleep. In addition, sleep apnea widely impacts the American population and is a large cost for healthcare. Traditional detection methods of sleep apneas are complex, expensive, and invasive to most patients. Among the various physiological signals, respiration signals are relatively easy to be monitored. However, not many studies are conducted using respiration signal only, and most of the previous algorithms are insufficient to detect apnea events...

In this paper we propose an on-the-fly reconfigurable hardware-software codesign based reconfigurable solution for real-time protein identification. Reconfigurable string matching is performed in the disciplines of protein identification and biomarkers discovery. With the generation of plethora of sequenced data and number of biomarkers for several diseases, it is becoming necessary to have an accelerated processing and on-the-fly reconfigurable system design methodology to bring flexibility to its usage in the medical science community without the need of changing the entire hardware every time with the advent of new biomarker or protein...

PURPOSE: To determine if a real-time magnetic resonance imaging (RT-MRI) method during continuous positive airway pressure (CPAP) can be used to measure neuromuscular reflex and/or passive collapsibility of the upper airway in individual obstructive sleep apnea (OSA) subjects. MATERIALS AND METHODS: We conducted experiments on four adolescents with OSA and three healthy controls, during natural sleep and during wakefulness. Data were acquired on a clinical 3T scanner using simultaneous multislice (SMS) RT-MRI during CPAP...

REVIEW
Vinay N Krishna, Kamesha Managadi, Michael Smith, Eric Wallace
Geographic and socioeconomic barriers may pose a significant difficulty in delivering home dialysis care to remote underserved populations leading to low utilization rates and poor outcomes. Telehealth may serve as a solution to overcome geographic barriers in delivering home dialysis care. Although technologic advances in telehealth have progressed rapidly making it accessible and inexpensive, it has been underused by nephrologists. Components of a regular face-to-face visit that can be successfully accomplished remotely using telehealth techniques include physician-patient communication, physical examination, laboratory and treatment data monitoring, nursing and nutrition education...

A novel polymeric bioflocculant was produced by a bacterium utilizing degradation of n-hexadecane as the energy source. The bioflocculant was produced with a bioflocculating activity of 87.8%. The hydrocarbon degradation was confirmed by gas chromatography-mass spectrometry analysis and was further supported with contact angle measurements for the changes in hydrophobic nature of the culture medium. A specific aerobic degradation pathway followed by the bacterium during the bioflocculant production and hydrocarbon utilization process has been proposed...

Intraluminal thrombus is a consistent feature of human abdominal aortic aneurysm (AAA). Coagulation factor Xa (FXa) catalyses FII to thrombin (FIIa). We examined the effect of FXa/FIIa inhibition on experimental aortic aneurysm in apolipoprotein E-deficient (ApoE(-/-)) mice infused with angiotensin II (AngII). The concentration of FXa within the supra-renal aorta (SRA) correlated positively with SRA diameter. Parenteral administration of enoxaparin (FXa/IIa inhibitor) and fondaparinux (FXa inhibitor) over 14 days reduced to severity of aortic aneurysm and atherosclerosis in AngII-infused ApoE(-/-) mice...

Brain-computer interfaces (BCIs) have the potential to restore communication for people with tetraplegia and anarthria by translating neural activity into control signals for assistive communication devices. While previous pre-clinical and clinical studies have demonstrated promising proofs-of-concept (Serruya et al., 2002; Simeral et al., 2011; Bacher et al., 2015; Nuyujukian et al., 2015; Aflalo et al., 2015; Gilja et al., 2015; Jarosiewicz et al., 2015; Wolpaw et al., 1998; Hwang et al., 2012; Spüler et al...

Regulatory T cells (Tregs) are critical for self-tolerance. While adoptive transfer of expanded Tregs limits graft-versus-host disease (GVHD) after hematopoietic cell transplantation (HCT), ex vivo generation of large numbers of functional Tregs remains difficult. Here, we demonstrate that in vivo targeting of the TNF superfamily receptor TNFRSF25 using the TL1A-Ig fusion protein, along with IL-2, resulted in transient but massive Treg expansion in donor mice, which peaked within days and was nontoxic. Tregs increased in multiple compartments, including blood, lymph nodes, spleen and colon (a GVHD target tissue)...

BACKGROUND: The knowledge of the current prevalence of lymphatic filariasis and its transmission will be helpful in its elimination. Thus, the present study is aimed to determine its prevalence among hydrocele patients which is a common presentation in chronically infected cases. MATERIALS AND METHODS: One hundred patients suffering from hydrocele admitted to the surgical ward were included in the study. Blood samples were collected from the patients during the day hours for the detection of anti-filarial antibody and during night hours to detect the presence of microfilaria by smear examination...

Chromhidrosis is a rare disorder in which there is pigmentation of sweat in a variety of colors. It can be classified into apocrine, pseudoeccrine, and true eccrine chromhidrosis. Pseudochromhidrosis is a condition in which the excreted sweat is colorless, but later acquires color due to contact with chromogenic chemicals. Systemic and topical antibiotics are the mainstay of treatment. Although it does not constitute a major health issue, it causes psychological stress and social embarrassment. A 20-year-old female presented to us with yellow-colored sweat and discoloration of clothes since 1 month...
