Noopur Kakde, Kashinath G Metri, Shivarama Varambally, Raghuram Nagaratna, H R Nagendra
Background Parkinson's disease (PD), a progressive neurodegenerative disease, affects motor and nonmotor functions, leading to severe debility and poor quality of life. Studies have reported the beneficial role of yoga in alleviating the symptoms of PD; however, a validated yoga module for PD is unavailable. This study developed and validated an integrated yoga module(IYM) for PD. Methods The IYM was prepared after a thorough review of classical yoga texts and previous findings. Twenty experienced yoga experts, who fulfilled the inclusion criteria, were selected validating the content of the IYM...

Duncan A Taylor, Oliva Handt, Damien Abarno, John Buckleton
We present here the derivation of paternity index formulae that covers situations of a disputed paternity trio with a trisomic product of conception. We consider six possible mechanisms for trisomy to occur: dispermy, dieggy, paternal meiosis I or II, and maternal meiosis I or II in the calculation. We also provide a biological explanation for how each of the mechanisms could give rise to a trisomy. The paper is set out in a general manner so that the tables presented can be used on any instance of trisomic offspring...

#3
Yoojin Lee, Martina F Callaghan, Zoltan Nagy
In magnetic resonance imaging, precise measurements of longitudinal relaxation time (T1) is crucial to acquire useful information that is applicable to numerous clinical and neuroscience applications. In this work, we investigated the precision of T1 relaxation time as measured using the variable flip angle method with emphasis on the noise propagated from radiofrequency transmit field ([Formula: see text]) measurements. The analytical solution for T1 precision was derived by standard error propagation methods incorporating the noise from the three input sources: two spoiled gradient echo (SPGR) images and a [Formula: see text] map...

Fatemeh Safa Shams Abyaneh, Mahboube Eslami Moghadam, Moayyed Hoseini Sadr, Adeleh Divsalar
Investigation of side effects and solubility of anticancer drugs is a major challenge in chemotherapy science. Thus, design and synthesis of cisplatin analogs with higher lipophilicity as novel water-soluble anticancer drugs is valuable. In this work, two new Pt (II) complexes were synthesized with formula cis-[Pt (NH3)2(amylgly)] NO3 and cis-[Pt (amylamine)2(amylgly)]NO3; where gly is penthyl glycine as an amino acid. The new compounds were synthesized and extensively characterized using analytical techniques; spectroscopic methods and conductivity measurement...

#5
Hyun Jeong Lee, Ji Young Min, Hyun Il Kim, Hyo-Jin Byon
BACKGROUND: Caudal blocks are performed through the sacral hiatus in order to provide pain control in children undergoing lower abdominal surgery. During the block, it is important to avoid advancing the needle beyond the sacrococcygeal ligament too much to prevent unintended dural puncture. This study used demographic data to establish simple guidelines for predicting a safe needle depth in the caudal epidural space in children. METHODS: A total of 141 children under 12 years old who had undergone lumbar-sacral magnetic resonance imaging were included...

REVIEW
Andrew M Jones, Anni Vanhatalo
The curvilinear relationship between power output and the time for which it can be sustained is a fundamental and well-known feature of high-intensity exercise performance. This relationship 'levels off' at a 'critical power' (CP) that separates power outputs that can be sustained with stable values of, for example, muscle phosphocreatine, blood lactate, and pulmonary oxygen uptake ([Formula: see text]), from power outputs where these variables change continuously with time until their respective minimum and maximum values are reached and exercise intolerance occurs...

Excess acquisition counts were often obtained by the current image acquisition of 30 minutes after (123)I-ioflupane administration in a dopamine transporter study. The purpose of this study was to calculate the minimum acquisition time while retaining sufficient image quality, which could be adjusted for individual characteristics. Fifty patients who underwent dopamine transporter imaging were included in this retrospective study. The brain count density, determined by a striatum phantom, was compared to the participant's characteristics...

OBJECTIVES: Conventional 2-stage expander-implant breast reconstruction is frequently performed. However, direct to implant reconstruction should be considered if indicated and if circumstances allow. One difficulty in breast reconstruction postmastectomy is selection of the appropriate implant size prior to surgery. The ability to estimate implant volume and mastectomy-specimen volume from the preoperative breast volume using a 3-dimensional (3D) scanner would greatly facilitate reconstruction...

Conditional power of survival endpoints at interim analyses can support decisions on continuing a trial or stopping it for futility. When a cure fraction becomes apparent, conditional power cannot be calculated accurately using simple survival models, e.g. the exponential model. Non-mixture models consider such cure fractions. In this paper, we derive conditional power functions for non-mixture models, namely the non-mixture exponential, the non-mixture Weibull, and the non-mixture Gamma models. Formulae were implemented in the R package CP...

Doppler-derived myocardial performance index are used to assess aspects of systolic and diastolic function in adult as well as fetal heart. The Tei Index (TI) is a useful and non-invasive tool. The aim of this study was to determine normal values of fetal left ventricular (LV) TI in early (16-32 weeks) and late trimester (35-41 weeks) fetuses and to develop a new myocardial performance index (K-index; KI) which focuses on fetal diastolic interval when oxygenated blood from the placenta filled in the LV. Simultaneous recordings of Doppler Ultrasound Signal (DUS) of the LV outflow tracts and fetal electrocardiogram signals were obtained in 55 early- and late-trimester fetuses...

The UV environment is a key boundary condition to abiogenesis. However, considerable uncertainty exists as to planetary conditions and hence surface UV at abiogenesis. Here, we present two-stream multilayer clear-sky calculations of the UV surface radiance on Earth at 3.9 Ga to constrain the UV surface fluence as a function of albedo, solar zenith angle (SZA), and atmospheric composition. Variation in albedo and latitude (through SZA) can affect maximum photoreaction rates by a factor of >10.4; for the same atmosphere, photoreactions can proceed an order of magnitude faster at the equator of a snowball Earth than at the poles of a warmer world...

AIM: Most epidemiological and clinical studies calculated low-density lipoprotein-cholesterol (LDL-C) by Friedewald's formula which cannot be used in the postprandial samples. Although the homogeneous assays with poor analytical performance were withdrawn from the market, it remained unclear whether the currently available reagents for LDL-C and high-density lipoprotein-cholesterol (HDL-C) are as accurate for postprandial samples as for fasting samples. METHODS: Fresh blood samples were collected from 59 non-diseased and 109 diseased subjects...

Toshiro Tango
Tango (Biostatistics 2016) proposed a new repeated measures design called the S:T repeated measures design, combined with generalized linear mixed-effects models and sample size calculations for a test of the average treatment effect that depend not only on the number of subjects but on the number of repeated measures before and after randomization per subject used for analysis. The main advantages of the proposed design combined with the generalized linear mixed-effects models are (1) it can easily handle missing data by applying the likelihood-based ignorable analyses under the missing at random assumption and (2) it may lead to a reduction in sample size compared with the simple pre-post design...
