Primary hepatic angiosarcoma is a rare type of tumor with a poor prognosis. To the best of our knowledge, curative surgery of a metastatic gastrointestinal angiosarcoma from a hepatic angiosarcoma has not been reported previously. In the present report, a case of colonic metastasis from a primary hepatic angiosarcoma is discussed. A rapidly growing mass was identified in the liver of an 84-year-old Japanese male who underwent a subsegmentectomy of the liver. Microscopic examination determined that the mass was an angiosarcoma composed of sheets of spindle cells...

The role of multidrug resistance associated protein 1 (MRP1) in the multidrug resistance (MDR) of colorectal cancer (CRC) remains unclear. The present study aimed to investigate the effect of MRP1 in MDR CRC and its therapeutic potential for the treatment of patients with this disease. The human MDR CRC cell lines HCT-8 and Colo205 were established through stable exposure to 5-florouracil (5-FU) over a 5-month period. MRP1 was knocked-down in MDR CRC cells through the transfection of short hairpin RNA targeting MRP1 (shMRP1)...

Melatonin, synthesized in and released from the pineal gland, has been demonstrated by multiple in vivo and in vitro studies to have an oncostatic role in hormone-dependent tumors. Furthermore, several clinical trials point to melatonin as a promising adjuvant molecule to be considered for cancer treatment. In the past few years, evidence of a broader spectrum of action of melatonin as an antitumor agent has arisen; thus, melatonin appears to also have therapeutic effects in several types of hormone-independent cancer, including ovarian, leukemic, pancreatic, gastric and non-small cell lung carcinoma...

Mutations of the tumor protein p53 gene, a tumor suppressor, are one of the most frequent genetic alterations observed in cancer. It has been reported that mutations in p53 result in the loss of wild-type p53 activity, and the gain of novel oncogenic properties that promote tumor growth and progression. Recent studies have demonstrated that a number of microRNAs (miRs) are involved in the post-transcriptional regulation of p53. The present study demonstrates that miR-600 is a direct negative regulator of p53 through binding a site in the 3' untranslated region of p53 mRNA in human colorectal cancer (CRC) cells...

The B-Raf proto-oncogene serine/threonine kinase (BRAF)(V600E) mutation is an important oncogene in the development of papillary thyroid carcinoma (PTC) and has been identified as a risk factor for poor prognosis in patients with PTC. However, whether the BRAF(V600E) mutation is a prognostic marker in patients with solitary papillary thyroid microcarcinoma (sPTMC) has not yet been established. The present study aimed to identify the association between BRAF(V600E) mutation and the clinicopathological features of patients with sPTMC...

A wide resection of the tumor with or without chemotherapy is the treatment of choice for periosteal osteosarcoma (PO) of the extremities, however, post-operative limb function and quality of life could be compromised. The present study reports two cases of 14-year-old boys who presented with progressively enlarging masses in their right knee regions. Computed tomography and magnetic resonance imaging scans indicated a fusiform space-occupying mass encircling the bone cortex, with stippled calcification. A diagnosis of PO was suspected...

Lipomas of the sigmoid colon are rare entities. The present case describes a 27-year-old Caucasian woman who underwent a laparoscopic sigmoidectomy following the detection of a giant lipoma. The young patient was referred to the Emergency Department of the University Hospital of Heraklion (Crete, Greece) in May 2013 after experiencing intermittent abdominal cramping during defecation, and altering episodes of diarrhea and constipation. In addition, the patient described the protrusion of a solid tissue mass shaped like a 'champagne bottle cork' from the anus following defecation...

Magnetic resonance imaging (MRI) with a gadolinium-based contrast agent is the gold standard for high-grade gliomas (HGGs). The compound 5-aminolevulinic acid (5-ALA) undergoes a high rate of cellular uptake, particularly in cancer cells. In addition, fluorescence-guided resection with 5-ALA is widely used for imaging HGGs. 5-ALA is water soluble, while protoporphyrin IX (PpIX) is water insoluble. It was speculated whether converting from 5-ALA to PpIX may relatively increase intracellular water content, and consequently, might enhance the T2 signal intensity in HGG...

MicroRNA (miRNA) are endogenous non-coding RNAs that suppress gene expression at the transcriptional, post-transcriptional or translational level by targeting the 3'-UTRs of specific mRNAs. miR-10a has been frequently reported to be aberrantly overexpressed in human tumors. In gastric cancer (GC), miR-10a has an important role in the metastasis from primary GC to lymph nodes. However, the role and relevant pathways of miR-10a in GC metastasis remain largely unknown. The present study was performed using 41 GC and 20 normal gastric mucosa tissues...

Gustavo Funes, Jaime Anguita
By means of an experimental setup, we study the time evolution of orbital angular momentum (OAM) crosstalk after a 5 m propagation path with a turbulence perturbation generated by a flat heater. This convective turbulence could simulate the beam passing over hot concrete or building roofs. We study the consequences of using a wide range of transmission OAM states. We also explore the effect of misalignment, and we propose two new different techniques for analyzing the vortex cancellation. Even though results are inconsistent with theoretical predictions, especially for low turbulence regimes, we state that signal-to-noise ratio is the key factor to understanding this discrepancy...

The tumor suppressor p53 is an essential gene in the induction of cell cycle arrest, DNA repair, and apoptosis. p53 protein is induced under cellular stress, blocking cell cycle progression and inducing DNA repair. Under DNA damage conditions, it has been reported that post-transcriptional regulation of p53 mRNA contributes to the increase in p53 protein level. Here we demonstrate that heterogeneous nuclear ribonucleoprotein (hnRNP) L enhances p53 mRNA translation. We found that hnRNP L is increased and binds to the 5'UTR of p53 mRNA in response to DNA damage...

A high proportion of patients presenting at epilepsy clinics experience functional non-epileptic attacks (FNEA), and while psychological treatment is generally thought to be the required intervention, evidence regarding psychological treatment of FNEA is limited. A small number of psychoeducation treatments have been evaluated, with promising results. As part of routine care within a neuropsychiatry service, a 3-session cognitive-behavior therapy- (CBT-) informed psychoeducation group was developed. Patients with comorbid epilepsy were included...

Microalgae are an alternative source for renewable energy to overcome the energy crises caused by exhaustion of fuel reserves. Algal biofuel technology demands a cost effective strategy for net profitable productivity. Inconsistent illumination intensities hinder microalgal growth. The light-utilizing efficiency of the cells is critical. Light scarcity leads to low production and high intensities cause photo-inhibition. We report effective usage of LEDs of different band wavelengths on the growth of microalgae in a closed, controlled environment to generate biomass and lipid yields...

The thermal denaturation of proteins was evaluated in the natural state of bovine muscle using differential scanning calorimetry (DSC). The Longissimus lumborum muscle was selected according to ultimate pH (pHu) values classified into two groups: low pHu with values between 5.4 and 5.8, and intermediate pHu with values between 5.81 and 6.19. The muscles were cut and aged at 2°C up to 21d post mortem. The three maximum temperatures of denaturation (Tmax1, Tmax2, Tmax3) found in muscle were evaluated, showing higher thermal stability in the intermediate pHu group, which could be an indicator of protection of proteins against aggregation or enzymatic activity...

Preventative psychological interventions to aid women after traumatic childbirth are needed. This proof-of-principle randomized controlled study evaluated whether the number of intrusive traumatic memories mothers experience after emergency caesarean section (ECS) could be reduced by a brief cognitive intervention. 56 women after ECS were randomized to one of two parallel groups in a 1:1 ratio: intervention (usual care plus cognitive task procedure) or control (usual care). The intervention group engaged in a visuospatial task (computer-game 'Tetris' via a handheld gaming device) for 15 min within six hours following their ECS...

BACKGROUND AND OBJECTIVES: Depression is common among persons with opioid use disorder. We examined the perceived need for depression treatment (PNDT) among opioid-dependent patients and the relationship of PNDT to depression screening result. METHODS: Between May and December 2015, we surveyed consecutive persons (n = 440) seeking inpatient opioid detoxification. We used the Patient Health Questionnaire-2 (PHQ-2) to screen for depression. To assess perceived need for depression services, participants were asked, "Do you believe you should be treated for depression?" Response options were recorded into four categories: "Not Depressed (ND)," "Perceive Need for Depression Treatment (PNDT)," "Depressed/Don't Want Treatment," and "Currently Treated...
