A new GPU-based Monte Carlo dose calculation algorithm (GPUMCD), developed by the vendor Elekta for the Monaco treatment planning system (TPS), is capable of modeling dose for both a standard linear accelerator and an Elekta MRI linear accelerator. We have experimentally evaluated this algorithm for a standard Elekta Agility linear accelerator. A beam model was developed in the Monaco TPS (research version 5.09.06) using the commissioned beam data for a 6 MV Agility linac. A heterogeneous phantom representing several scenarios - tumor-in-lung, lung, and bone-in-tissue - was designed and built...

INTRODUCTION: To quantify acetabular version using 3D reconstructions based on biplanar radiographs (BPR) with CT as reference standard. MATERIALS AND METHODS: No institutional review board approval was needed. Nine dry-bone pelvises underwent BPR in five different positions (rotation/tilt). 3D models of each pelvis were reconstructed by two radiologists on the basis of anatomical landmarks using semi-automated software. Automated software was used to assess the 3D models and to calculate acetabular versions perpendicular to the anterior pelvic plane on all levels in the craniocaudal direction in 1mm steps...

Evidence from the literature suggests that, on average, 27% of patients with a bipolar disorder (BD) experience a continuous cycling course (CCC) and that this subgroup differs significantly from patients with a noncontinuous cycling course (N-CCC) with respect to sociodemographic characteristics and clinical presentation. The aim of the present paper is to review the studies that evaluated short- and long-term treatment responses in BD patients with CCC. The retrieved studies indicate that CCC is a significant predictor of poor response to long-term treatment with lithium (the odds of a response in the CCC group were 57% less than in the N-CCC group; p<0...

Clear cell carcinoma of the thyroid has been regarded as a variant of follicular (FTC) or papillary (PTC) thyroid carcinoma. 21 primary thyroid carcinomas with clear cell features, diagnosed in 20 patients (12 female, 8 male) were identified between 1992 and 2012 (0.5% of in-house thyroid carcinomas). H&E slides were reviewed. SNaPshot multi-gene mutational analysis and a translocation panel were successfully performed on 15 of these cases. 12 (57%) were FTC, 5 were conventional PTC, 2 were follicular variant (FV) of PTC, and 2 were poorly differentiated thyroid carcinoma (PDTC)...

Primary clear cell colorectal carcinoma (CCC) is a very rare entity accounting for only 35 cases reported in the Literature. CCC is neither classified as a distinct entity nor is it defined as a CRC variant because its ontogeny remains unclear. Most of the reported CCC were found in the distal colon in patients with a mean age of 56 years. Histologically, clear cell change is the main morphologic feature and may present in a "pure" form, composed exclusively of clear cells, or in a "composite" form, admixed with other morphologically different components...

Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix...

Undifferentiated/dedifferentiated endometrial carcinomas (UCE/DCEs) of the endometrium are rare tumors with poor prognosis. There are few clinicopathologic studies with detailed immunohistochemical analysis regarding UCE/DCEs.We evaluated the diagnostic value of a selected tumor stem-cell marker and epithelial-mesenchymal transition (EMT) markers, in addition to previously studied markers in identifying UCE/DCEs from other types of high-grade endometrial carcinomas.Eleven cases of UCE/DCEs with complete clinical follow-up that were diagnosed between 2006 and 2015 were included in the study...

REVIEW
Parli R Ravi, Bipin Puri
This brief update reviews the recent literature available on fluid resuscitation from hemorrhagic shock and considers the applicability of this evidence for use in resuscitation of combat casualties in the combat casualty care (CCC) environment. A number of changes need to be incorporated in the CCC guidelines: (1) dried plasma (DP) is added as an option when other blood components or whole blood are not available; (2) the wording is clarified to emphasize that Hetastarch is a less desirable option than whole blood, blood components, or DP and should be used only when these preferred options are not available; (3) the use of blood products in certain tactical field care settings where this option might be feasible (FSC, GH) is discussed; (4) 1:1:1 damage control resuscitation (DCR) with plasma: packed red blood cells (PRBC): platelets is preferred to 1:1 DCR with plasma: PRBC when platelets are available; and (5) the 30-min wait between increments of resuscitation fluid administered to achieve clinical improvement or target blood pressure has been eliminated...

Countercurrent chromatography (CCC) is an efficient separation technique without the solid support matrix, largely depending on the partition of two-immiscible liquid phases in the separation column. Since the helical coil planet centrifuge was invented in early 1970s by Yoichiro Ito, a series of coils columns, including spiral coils and conical coils columns have been developed for CCC separation. In this work, we introduced a new simple and efficient concentrical coils column for CCC separation, which was prepared by winding the whole polytetrafluoroethylene (PTFE) tube into the circular grooves from the rotation axis in the same direction...

This work evaluated the National Research Council (NRC) dairy model (2001) predictions of rumen undegradable (RUP) and degradable (RDP) protein compared with measured postruminal non-ammonia, nonmicrobial (NANMN) and microbial N flows. Models were evaluated using the root mean squared prediction error (RMSPE) as a percent of the observed mean, mean and slope biases as percentages of mean squared prediction error (MSPE), and concordance correlation coefficient (CCC). The NRC (2001) over-estimated NANMN by 18% and under-estimated microbial N by 14%...

Evaluation of ration balancing systems such as the National Research Council (NRC) Nutrient Requirements series is important for improving predictions of animal nutrient requirements and advancing feeding strategies. This work used a literature data set (n = 550) to evaluate predictions of total-tract digested neutral detergent fiber (NDF), fatty acid (FA), crude protein (CP), and nonfiber carbohydrate (NFC) estimated by the NRC (2001) dairy model. Mean biases suggested that the NRC (2001) lactating cow model overestimated true FA and CP digestibility by 26 and 7%, respectively, and under-predicted NDF digestibility by 16%...

Consistency of dual-energy X-ray absorptiometry (DXA) scan results is critical for data integrity. For pediatric subjects, the extent to which cross-calibration of DXA scanners alleviates model-to-model scanner differences is unclear. In the current study, DXA bone outcomes were compared for same-day measurements performed using different scanners, cross-calibrated to alleviate discrepancies (Hologic; Discovery A [DISCO] and QDR 4500W [QDR]). Interscanner differences were evaluated in approximately 130 females aged 8-24 yr...

The potato (Solanum tuberosum L.) is the fourth most important crop food in the world and Colombia has one of the most important collections of potato germplasm in the world (the Colombian Central Collection-CCC). Little is known about its potential as a source of genetic diversity for molecular breeding programs. In this study, we analyzed 809 Andigenum group accessions from the CCC using 5968 SNPs to determine: 1) the genetic diversity and population structure of the Andigenum germplasm and 2) the usefulness of this collection to map qualitative traits across the potato genome...

Arsenic (As) is a common trace element whose oxidation states mainly include four types (-3, 0, +3, and +5), and inorganic As(III) and As(V) are regarded as the most commonly existing forms in aqueous environments. Generally, As(III) has a higher toxicity than As(V) due to the different mechanisms in arsenic toxicity. However, there are few studies about the water quality criteria (WQC) of As(III) and As(V) respectively because of the deficiency of arsenic toxicity data coming from diverse taxonomic groups...

A simple and efficient method based on ultrafiltration liquid chromatography-mass spectrometry (UFLC-MS) was applied to rapidly screen and identify ligands for lactate dehydrogenase (LDH) from the flowers of Pueraria lobata, and the compounds were assessed for anti-stroke activity using a PC12 cell model. Seven major isoflavones, kakkalide, 3'-hydroxy puerarin, puerarin, puerarin xyloside, tectoridin, tectorigenin, and ononin, were identified as potent LDH inhibitors. A continuous online method, which consisted of microwave-assisted extraction and countercurrent chromatography (MAE-CCC), was newly developed for scaled-up production of these compounds with high purity and efficiency...

Counter-current chromatography (CCC) is an efficient liquid-liquid partition chromatography technique without support matrix. Despite there are many significant advancements in the CCC separation of natural products especially for non-ionic neutral compounds, CCC isolation of ionic compounds including alkaloids is still a challenging process guide by classical partition coefficients (K) or distribution ratio (KC) because their partition coefficient could not be equal to distribution ratio in common ionic conditions...

This study investigated the relationships between methane (CH4) emission and fatty acids, volatile metabolites (V) and non-volatile metabolites (NV) in milk of dairy cows. Data from an experiment with 32 multiparous dairy cows and four diets were used. All diets had a roughage : concentrate ratio of 80 : 20 based on dry matter (DM). Roughage consisted of either 1000 g/kg DM grass silage (GS), 1000 g/kg DM maize silage (MS), or a mixture of both silages (667 g/kg DM GS and 333 g/kg DM MS; 333 g/kg DM GS and 677 g/kg DM MS)...

A novel application of counter-current chromatography (CCC) to enrich plant extracts using direct and continuous injection (CCC-DCI) was developed to fractionate sesquiterpenoids from the buds of Tussilago farfara L. In this study, an n-hexane-acetonitrile-water (HAcW) solvent system was separately pumped into the CCC column, and an extraction solution (45% acetonitrile) was directly and continuously injected into the CCC column. Since the extraction solution was used as a mobile phase in this method, solvent consumption could be greatly reduced...

Chlormequat Chloride (CCC), a widely used plant growth regulator, could decrease body weight in animals; however, the mechanism has not been well studied. This study was designed to evaluate the skeletal development toxicity of CCC on pubertal male Sprague-Dawley (SD) rats and to investigate whether CCC impacts the development of chondrocyte, osteoblast and osteoclast through growth hormone (GH) and insulin like growth factor 1 (IGF-I). Rats from 23 to 70 on postnatal days were exposed to CCC daily by gavage at doses of 0, 75, 150, and 300mg/kg bw/d...
