Solid papillary carcinomas are tumors morphologically characterized by round, well-defined nodules composed of low-grade ductal cells separated by fibrovascular cores. These tumors are rare and affect predominantly older women. Although they are considered in situ carcinomas, debate and uncertainty still exist regarding their true nature, because immunohistochemistry for myoepithelial cells ...

Peritoneal carcinomatosis (PC) carries a worse prognosis than other sites of colorectal metastases. If incomplete resection of PC affords no benefit to patients, complete resection of PC is beneficial in selected patients. The combination of complete cytoreductive surgery to treat the visible PC and hyperthermic intraperitoneal chemotherapy (HIPEC) to treat ...

An 18-month-old male basset hound was presented with vomiting, diarrhoea and depression. Abdominal ultrasonography revealed a mass in the left kidney. An ultrasound-guided core-biopsy indicated aggregates of spindle cells, but did not allow a definitive diagnosis. Nephrectomy was performed after a period of six months, when ultrasound examination revealed a ...

Inappropriate complementary feeding practices have led to, in part, significant disparities in growth and nutritional status between rural and urban children in China. A cluster-randomised, controlled trial was implemented in Laishui, China to assess the effectiveness of an educational intervention on caregivers' feeding practices and children's growth. Eight townships were ...

Oncology nurses caring for patients with complex medical, psychosocial, and spiritual issues-including patients at end of life-rely on current medical interventions to offer comfort to their patients. Equally important, but less acknowledged, is nurses' reliance on the internal processes of reflection and self-care. That internal focus is vital to the ...

Pulsed laser ablation for the direct synthesis of single-wall carbon nanotube/PbS-quantumdot(SWCNT/PbS-QD) nanohybrids is demonstrated. The latitude of the developed pulsed laser deposition process permits not only the control of the size of the PbS-QDs but also the straightforward integration of these novel SWCNT/PbS-QD nanohybrids into photoconductive (PC) devices. Thus, by ...

College students are susceptible to upper respiratory infections (URI) due to inadequate sleep, stress and close living quarters. Certain probiotic strains modulate immune function and may improve health-related quality of life (HRQL) during URI. The present study recruited apparently healthy college students and assessed the effect of probiotics on HRQL ...

Abstract Purpose: In the classical description of acute radiation syndrome, the role of central nervous system (CNS) is underestimated. It is now well recognised that ionising radiation induced oxidative stress may bring about functional changes in brain. In this study, we prospectively evaluated metabolic changes in brain after whole body ...

The present study examined if an elevated nitrate intake would improve VO(2) kinetics, endurance, and repeated sprint capacity in elite endurance athletes. Ten highly trained cyclists (72 ± 4 mL O(2) /kg/min, mean ± standard deviation) underwent testing for VO(2) kinetics (3 × 6 min at 298 ± 28 W), endurance (120 min preload followed by a 400-kcal time trial), and repeated ...

A novel photochromic azobenzene-based surfactant was described for organic chemistry in water. The molecule BABTGA thus synthesized can be isomerised from its trans to its cis form reversibly in solution by simple light irradiation. That property allowed the recyclability of a model acetylation reaction performed in the surfactant media, compared ...

For northern taxa, persistence in multiple vs. single Pleistocene refugia may have been an important determinant of contemporary range size, with larger ranges achieved by species that colonized the north from several glacial refugia. Under this hypothesis, widespread species are expected to demonstrate marked phylogeographic structure in previously glaciated regions. ...

Hyperphosphatemia has clinically been associated with total mortality and cardiovascular mortality in patients with chronic renal failure (CRF). Recently, higher serum phosphate levels within the normal range have been shown to be associated with substantially increased risk of cardiovascular events even in patients without CRF. Therefore, it is clear that ...

The incidence of concurrent breast cancer and pregnancy (also known as pregnancy-associated breast cancer [PABC]) may increase as women delay child bearing. Because of the physiologic changes associated with pregnancy, diagnosis often is delayed, lending to poorer prognostic factors on presentation. Therefore, the clinical challenge in managing PABC involves controlling ...

Functional motor recovery after peripheral nerve injury is predominantly determined by the time to motor end plate reinnervation and the absolute number of regenerated motor axons that reach target. Experimental models have shown that axonal regeneration occurs across a supercharged end-to-side (SETS) nerve coaptation. In patients with a recovering proximal ...

Chloroplast biogenesis needs to be well coordinated with cell division and cell expansion during plant growth and development to achieve optimal photosynthesis rates. Previous studies showed that gibberellins (GAs) regulate many important plant developmental processes, including cell division and cell expansion. However, the relationship between chloroplast biogenesis with cell division ...

Osteocyte expresses molecules responsible for hereditary hypophosphatemic rickets such as FGF23, DMP1 and PHEX. FGF23 exerts its effects in kidney by decreasing both renal phosphate (Pi) reabsorption and vitamin D activation. It is suggested that DMP1 and PHEX negatively regulate the expression of FGF23, although the underlying mechanisms remain to ...

This project aimed to improve RNs' recognition of and appropriate responses to failure to rescue situations on a surgical oncology unit. Simulation exercises played a key role in identifying areas of strength, opportunities for improvement, and development of a personalized education plan. In addition, the exercises improved RNs' clinical confidence.

While most lung neoplasms are malignant, a subset of true neoplasms are benign, the most common of which are pulmonary hamartomas. In addition, a substantial proportion of lung mass lesions are nonneoplastic; granulomas are among the commonly encountered nonneoplastic masses. There is also a group of relatively rare, mainly inflammatory ...

Background. In clinical practice, the identification of the culprit vessel and the localization of the occlusion site in ST-elevation myocardial infarction (STEMI) are provided by coronary angiography. Over the last few years, however, an increasing body of literature focused upon the reassessment of the ECG as a reliable technique to ...

The indications for peritonectomy + hyperthermic intraperitoneal chemotherapy (HIPEC) are based on careful assessment of disease extent, but no imaging procedure is accurate enough to identify lesions smaller than 5 mm or extensively diffuse. Video-laparoscopy allows, with minimal surgical trauma, correct staging with a reliable prediction of expected cytoreduction index. Operative ...

In this study, we demonstrate a new strategy to image biomolecular events through interactions between liquid crystals (LCs) and oil-in-water emulsions. The optical response had a dark appearance when a nematic LC, 4-cyano-4'-pentylbiphenyl (5CB), is in contact with emulsion droplets of glyceryl trioleate (GT). In contrast, the optical response had ...

Background.  The risk of a subsequent cancer is an important issue for patients with melanoma. The development of a second primary cancer in patients with a solitary melanoma has been discussed in several studies. However, to our knowledge, the incidence of second primary cancer (SPC) in patients with multiple primary ...

BACKGROUND: Recent models of major depressive disorder (MDD) have proposed the rostral anterior cingulate (rACC) and dorsomedial prefrontal cortex (dmPFC) as nexus sites in the dysfunctional regulation of cognitive-affective state. Limited evidence from remitted-state MDD supports these theories by suggesting that aberrant neural activity proximal to the rACC and the ...
