AIM: To evaluate the impact of radiochromic film positioning relative to the central beam axis (CAX) in proton beam therapy. Secondarily, to compare the dosimetric measurements obtained by RTQA and EBT film and to compare these to the doses calculated by the treatment planning system (TPS). METHODS: EBT and RTQA dosimetric radiochromic films were immersed in a water phantom and irradiated with a proton beam. The films were placed parallel to the CAX and at a 5º angle on the horizontal plane to assess the effect of film inclination on Bragg peak profiles...

The Ponseti method to treat idiopathic clubfoot deformity has proven to be reliable, and several centers have reported excellent outcomes. Although the method has been dependable in obtaining initial correction of the foot, relapse rates ranging from 26% to 48% have been reported. When a relapsed deformity is detected early, treatment with a short series of manipulations and cast applications followed by resumption of postcorrective bracing may be all that is required to regain and maintain correction. In patients aged >2...

A 17-year-old female wolf (Canis lupus lupus) had a right lung mass that was adhered to the thoracic cavity. Histopathological examination revealed that the mass consisted of sheets, cord or ribbon-like structures of monotonous, small, cuboidal cells with round, oval or short-spindle nuclei and scant clear cytoplasm, demarcated by a fine fibrovascular stroma. Focal necrosis, congestion and thrombi were observed. Immunohistochemically, the tumor cells diffusely expressed cytokeratin AE1/AE3, and some expressed chromogranin A, neural cell adhesion molecule (CD56) and thyroid transcription factor-1...

Ophthalmology and visual health research have received relatively limited attention from the personalized medicine community, but this trend is rapidly changing. Postgenomics technologies such as proteomics are being utilized to establish a baseline biological variation map of the human eye and related tissues. In this context, the choroid is the vascular layer situated between the outer sclera and the inner retina. The choroidal circulation serves the photoreceptors and retinal pigment epithelium (RPE). The RPE is a layer of cuboidal epithelial cells adjacent to the neurosensory retina and maintains the outer limit of the blood-retina barrier...

We experienced 2 cases of Müllerian cyst. Case 1 was a 48-year-old woman with a paravertebral cystic tumor. The tumor grew from 23 to 31 mm in diameter for the 3 years. She underwent video-assisted thoracic surgery(VATS) for the excision of the tumor. Case 2 was a 40-year-old woman with a paravertebral cystic tumor, who underwent VATS. The Histological finding showed that the tumors of both cases were the cysts lined by non-stratified cuboidal to columnar epithelium and epithelial cells were positive in the nucleus with estrogen receptor immunohistochemically...

: While titanium alloys represent the current state-of-the-art for orthopedic biomaterials, concerns still remain over their modulus. Circumventing this via increased porosity requires high elastic admissible strains, yet also limits traditional thermomechanical strengthening techniques. To this end, a novel β-type Ti-Zr-Ta alloy system, comprised of Ti-45Zr-10Ta, Ti-40Zr-14Ta, Ti-35Zr-18Ta and Ti-30Zr-22Ta, was designed and characterized mechanically and microstructurally. As-cast, this system displayed extremely high yield strengths and elastic admissible strains, up to 1...

Many synthesis parameters can influence zeolite crystallization, which include the molar ratio of reagents, water content, temperature, the selection of extraframework cations (organic or inorganic template) and so on. In this paper, two new materials, BUCT-1 with cuboid morphology and BUCT-2 with plate-like morphology were obtained based on the synthesis conditions of ITQ-17 by adjusting the GeO2/SiO2 ratio, H2O/TO2 ratio and temperature. The influence of the three factors on crystal size, crystallinity and phase selection and transformation was carefully discussed...

Commercial mushroom growth on substrate material produces a heterogeneous waste that can be used for bioenergy purposes. Hyperspectral imaging in the near-infrared (NHI) was used to experimentally study a number of spent mushroom substrate (SMS) packed samples under different conditions (wet vs. dry, open vs. plastic covering, and round or cuboid) and to explore the possibilities of direct characterization of the fresh substrate within a plastic bag. Principal components analysis (PCA) was used to remove the background of images, explore the important studied factors, and identify SMS and mycelia (Myc) based on the pixel clusters within the score plot...

The functional unit of the thyroid gland, the thyroid follicle, dynamically responds to various stimuli to maintain thyroid hormone homeostasis. However, thyroid follicles in the adult human thyroid gland have a very limited regenerative capacity following partial resection of the thyroid gland. To gain insight into follicle regeneration in the adult thyroid gland, we observed the regeneration processes of murine thyroid follicles after partial resection of the lower third of the thyroid gland in 10-week-old male C57BL/6 mice...

To clarify the mechanism underlying the development of foot disorders such as diabetic ulcers and deformities, it is important to understand how the foot surface elongates and contracts during gait. Such information is also helpful for improving the prevention and treatment of foot disorders. We therefore measured temporal changes in the strain distribution on the foot surface during human walking. Five adult male participants walked across a glass platform placed over an angled mirror set in a wooden walkway at a self-selected speed and the dorsolateral and plantar surfaces of the foot were filmed using two pairs of synchronized high-speed cameras...

Chibby1 (Cby1) was originally isolated as a binding partner for β-catenin, a dual function protein in cell-cell adhesion and in canonical Wnt signaling. The canonical Wnt/β-catenin pathway is dysregulated in various diseases including cancer, most notably of the gastrointestinal origin. To investigate the role of Cby1 in colorectal tumorigenesis, we generated stable Cby1-knockdown (KD) SW480 colon cancer cells. Unexpectedly, we found that Cby1 KD induces mesenchymal-to-epithelial transition (MET)-like changes in SW480 as well as in HEK293 cells...

Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA) is a rare neoplasm characterized by morphological analogy to papillary thyroid carcinoma and abnormal expression of thyroid transcription factor-1 (TTF-1). We herein report a rare case of TL-LGNPPA with a review of its clinical, morphological and immunohistochemical characteristics. The patient was a 25-year-old Japanese woman complaining of a 2-year history of fever of unknown origin. There were no remarkable physical findings and the laboratory tests, including C-reactive protein levels, were normal...

True epithelial-lined cysts are rare forms of adrenal cystic lesions, the pathogenesis of which is still not fully understood. In this report we present a case of an adrenal cyst diagnosed incidentally on imaging in a 31-year-old, previously healthy, obese woman. Due to non-specific hormonal disorders and enlargement of the lesion, a right-sided laparoscopic adrenalectomy was performed. The cyst was lined predominantly by ciliated cuboidal-to-columnar, Müllerian-type epithelium, and focally by flat-to-cuboidal, mesothelium-like lining...

Cholangiocarcinoma, also referred to as cholangiocellular carcinoma (particularly in Japan), develops along the biliary tract. The tumor may be intra- or extrahepatic and have different features with specific treatments based on the site of origin. Guidelines for diagnosis and management of cholangiorcarcinoma, such as those proposed by EASL (European Association for the Study of the Liver)(1) and the Mayo Clinic(2) classify the tumor into intrahepatic, perihilar, and distal cholangiocarcinoma. There are three main macroscopic patterns of growth of cholangiocarcinoma: mass-forming, periductal-infiltrating and intraductal...

Cubosomes are micro- and nanoparticles with a bicontinuous cubic two-phase structure, reported for the self-assembly of low molecular weight surfactants, for example, lipids, but rarely formed by polymers. These objects are characterized by a maximum continuous interface and high interface to volume ratio, which makes them promising candidates for efficient adsorbents and host-guest applications. Here we demonstrate self-assembly to nanoscale cuboidal particles with a bicontinuous cubic structure by amphiphilic poly(ionic liquid) diblock copolymers, poly(acrylic acid)-block-poly(4-vinylbenzyl)-3-butyl imidazolium bis(trifluoromethylsulfonyl)imide, in a mixture of tetrahydrofuran and water under optimized conditions...

We were the first to examine the mechanical responses of skeletally mature bovine femoral cartilage under large-strain simple shear (up to ±20%) using a multiaxial shear testing device. Since shear loading is critical in both tissue failure and chondrocyte responses, we aimed to probe (1) anisotropy with respect to the split-line direction (principal alignment of the collagen fibers near the articulating surface), (2) heterogeneity between femoral condyles, and (3) the influence of local cartilage thickness...

The immune function of the chicken spleen depends on its different compartments of red and white pulps, but little is known about the mechanism underlying lymphocyte homing towards the different compartments. In the present study, the role of lymphocyte homing in the chicken spleen was investigated during lipopolysaccharide (LPS) stimulation. Morphological analysis demonstrated the cuboidal endothelial cells of the splenic sheathed capillary facilitated the passage of lymphocyte homing to the chicken spleen...

The os peroneum (OP) is a small sesamoid bone located inside the peroneus longus tendon (PLT), close to the cuboid. The OP can be the cause of pain and can be associated with lesions of the PLT. OP involvement in PLT disorders is frequently misdiagnosed by radiologists. Painful os peroneum syndrome (POPS) refers to a variety of conditions presenting with pain localized on the lateral aspect of the cuboid area. The syndrome can be observed as a consequence of local acute trauma such as ankle sprains or chronic overuse...

BACKGROUND: Melanoma is a highly metastatic type of cancer that is resistant to all standard anticancer therapies and thus has a poor prognosis. Therefore, metastatic melanoma represents a significant clinical problem and requires novel and effective targeted therapies. The protein kinase C (PKC) family comprises multiple isoforms of serine/threonine kinases that possess distinct roles in cancer development and progression. In this study, we determined whether inhibition of PKC could revert a major process required for melanoma progression and metastasis; i...
