| The nerve entry points (NEPs) cannot be accurately localized for the treatment of muscle spasticity in neurolysis. The aim of this study was to develop a new method of accurately localizing nerve entry points in relation to bony landmarks. NEPs in human cadavers were coated with barium sulfate. Method 1 consisted of horizontal and longitudinal reference lines being designated based on bony landmarks, followed by radiography and measurements using picture archiving and communication system software. Method 2 involved sewing the barium sulfate-soaked suture thread into the skin to designate the horizontal and longitudinal reference lines, followed by computed tomography (CT) scanning to determine the skin surface location and puncture depth for the NEPs.... |

| In this paper we develop a method to estimate lung volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: V*L = 0.496 · V RX ≈ 1/2·V RX , where V RX is a measurement obtained from the x-ray that represents the volume of a rectangular box containing the lungs and mediastinum organs. The proposed formula may be interpreted as the volume of an ellipsoid formed by both lungs joined at their bases. When that relationship was used to estimate lung volume, values similar to those expected from allometric relationship were found in four rodents. In two others, M. musculus and R. norvegicus, lung volume was similar to reported data, although... |

| The aim of this study was to assess a bilateral comparison of the mandible density in both sex young patients with computer densitometry. Fifty panoramic radiographs were obtained from young patients with ages between 18 and 23 years old (group A = 25 female and group B = 25 male) standardized, using the same X-Ray equipment (Siemens, lOKvp, 7mA), scanned with a 282.110 pixels resolution, and transferred later to a computer and using the SIDEXIS (Sirona, USA) program to analyze the bone densitometry performance. Bilateral sites were standardized with the objective to measure the bone density. Obtained data were registered and submitted to statistical analysis. The following means and standard deviations were obtained, in pixels, for the right and the left... |

| The objective of the present study was to establish a relationship between mericarps color and internal morphology of parsley with the germination, using sorting by coloration and the X-ray test. The completely randomized design was used, with four replications per treatment. The treatments were constituted of four lots (A, B, C and D) and three mericarps colors (green, yellow and black) in 4×3 factorial experiment. The mericarps were exposed to X-ray test (60s; 20kV), being used the digital equipment Faxitron X-ray, model MX-20 DC12 and then, the irradiated mericarps were submitted to the germination test. The yellow mericarps showed higher germination and speed germination index. The green mericarps showed deformations and impaired formation of embryo,... |

| Structural differences such as abnormalities, damage and free spaces in seeds may affect germination. The aim of this study was to study the relationship between eggplant seed morphology and seed germination. Ten seed lots of the eggplant cultivar Embu were evaluated by X-ray image analysis and the germination test. Seed image analysis was performed by Image Pro Plus® software and the whole seed area and free space between the embryo and endosperm were measured. The internal seed area filled by the embryo and endosperm was calculated from the difference between the whole seed and free space areas. Based on these results and visual seed analysis, seeds were classified into three categories and information on germination was obtained for each one. X-ray... |

| It is shown in the present paper how the addition of a moderate amount of carbon black filler to a polychloroprene gum modifies the local strain state and alters the ability of the polymer to strain-crystallize. The study combines mechanical and X-ray diffraction performed during classical mechanical cycling and tensile impact tests. It highlights the fact that the strain modification induced by the filler addition is highly inhomogeneous: the crystallization behavior and the local draw ratio state are affected differently. The partial relaxation of the amorphous fraction by the strain-induced crystallization peviously evidenced in the pure gum is still present and should play a protective role. The effect of temperature on the crystallization correlates... |

| Polychloroprene rubber is often quoted as an example of strain-crystallizing elastomer; however, this fundamental property, known to impart good mechanical properties and fatigue resistance, has received much less attention in this class of compounds than natural rubber. The present paper relates systematic investigations combining mechanical and X-ray diffraction measurements. Crystallization kinetics are first investigated based on tensile impact tests. An approximately logarithmic time-dependence is found for the crystalline content and the time-constants are estimated at various temperatures. The impact of strain-induced crystallization on stress-strain curves under mechanical cycling conditions is further assessed. It is demonstrated that one main... |

| Series of novel coumarin derivatives [I (a–d) and II (a–d)] were successfully synthesized and their structures were determined based on infrared 1H-nuclear magnetic resonance (NMR), HRMS, and single crystal X-ray crystallography. Additionally, the new synthesized compounds were evaluated to identify the molecular characteristics that contribute to their cytotoxicity, which was tested against SK-LU-1, SPC-A-1 and 95D human lung cancer cell lines, using the MTT assay. The results of this study showed that compounds Ic, Id, IIc, and IId exhibited an efficient percentage of inhibition of cell proliferation. |

| ABSTRACT N-acylhydrazone is an interesting privileged structure that has been used in the molecular design of a myriad of bioactive compounds. In order to identify new antinociceptive drug candidates, we described herein the design, synthesis, X-ray diffraction study and the pharmacological evaluation of a series of 3-amino-4-methylthiophene-2-acylcarbohydrazone derivatives (8a-t). Compounds were prepared in good overall yields through divergent synthesis from a common key intermediate and were characterized by classical spectroscopy methods. X-ray diffraction study was employed for unequivocal determination of the imine double bond stereochemistry. 8a-t were evaluated in vivo through oral administration using the classical writhing test in mice.... |

| ABSTRACT: Successive cycles of water absorption and loss favor weathering deterioration, one of the main factors that affect the quality of soybean seeds. This study evaluated the physiological, physical, and morpho-anatomical changes in soybean seeds under weathering deterioration at the pre-harvest phase. Six soybean cultivars (BMX Apolo, DM 6563, NS 5959, NA 5909, BMX Potência, and TMG 1175) were produced in a greenhouse and underwent weathering deterioration through a rainfall simulation system, applying 0, 60, 120, and 180 mm of precipitation at pre-harvest phase. Each rainfall level was divided into two applications at an interval of 72 h: 60 mm (30 + 30), 120 mm (60 + 60), and 180 mm (90 + 90). After harvest, the seeds were evaluated for... |

| カメの体幹部は甲羅に覆われているため、単純Ｘ線撮影では得られる情報が少ない。そこで今回、ミシシッピーアカミミガメに対するＸ線CTによる断層撮影検査の有用性について検討した。まず基礎的検討として、臨床的に健康な6匹を用い、軟部組織、肺および骨のCT値を計測し、その結果からそれぞれの組織の観察に適したウインドウを設定した。また、病理学的検索の結果、全ての個体において肝臓の脂肪変性が認められ、肝臓のCT値が低い個体ほど変性の程度が大きく、CT値の高い個体ほど変性の程度が小さかった。このことから、肝臓のCT値の差により脂肪変性の程度を診断することが可能であった。さらに、臨床例についてCT検査を実施したところ、それぞれ、消化管内異物、肺炎および卵塞の診断が可能であった。以上の成績より、ミシシッピーアカミミガメの臨床診断において従来の単純Ｘ線撮影では読影が困難であった体幹部軟部組織について、CTにより詳細な情報を得ることが可能であった。よって、カメの臨床診断にはCTによる断層画像診断の積極的な利用が望まれる。 In turtles，conventional radiographic techniques give little information on the interna1 organs because of the density of the shell. Therefore， computed tomography (CT) was attempted in six clinically normal red-eared sliders(Trachemys scripta elegans). The CT values were measured in soft tissues such as the... |
