BACKGROUND: Bioactive plant secondary metabolites have complex chemical structures, which are specific to each plant species/family, and accumulate in tiny amounts. The growing market demand for many phytochemicals can lead to the over-harvesting of medicinal plants in their natural habitat, endangering species in the process. OBJECTIVE: An ongoing challenge for our society is therefore to develop a bio-sustainable production of phytochemicals, among other natural resources...

The great cormorant (Phalacrocorax carbo) is widely distributed in the world. Here, we report the complete mitogenome sequence of P. carbo, which was 18,995 bp long and composed of 15 protein-coding genes, 25 tRNA genes, 2 rRNA genes and 2 control regions. Most genes were located on H-strand except for 10 tRNAs and 2 ND6 genes. In protein-coding genes, ATG, ATC and GTG were used as initiation codons, and TAA, AGA, AGG and TAG were used as stop codons. The 25 tRNA genes ranged in size from 67 to 75 bp. And 12S and 16S rRNA were respectively 983 and 1517 bp...

Anaplastic thyroid carcinoma (ATC) is aggressive and lethal with extrathyroidal invasion, distant metastasis, and resistance to conventional therapies. Cancer stem cells (CSCs) are proposed to be responsible for high recurrence rate in ATC. MicroRNAs (miRNAs) have recently been found as an important class of cellular regulators of ATC carcinogenesis. Identification of CSC-related miRNAs and targets is therefore a priority for the development of new therapeutic paradigms. Patient-derived ATC cells were cultured in conditional media on poly-hema-treated dish...

Anaplastic thyroid cancer (ATC) has a median survival less than 5 months and, to date, no effective therapy exists. Taxanes have recently been stated as the main drug treatment for ATC, and the histone deacetylase inhibitor valproic acid efficiently potentiates the effects of paclitaxel in vitro. Based on these data, this trial assessed the efficacy and safety of the combination of paclitaxel and valproic acid for the treatment of ATC. This was a randomized, controlled phase II/III trial, performed on 25 ATC patients across 5 centers in northwest Italy...

Adverse drug events (ADEs) are more likely to affect geriatric patients due to physiological changes occurring with aging. Even though this is an internationally recognized problem, similar research data in Finland is still lacking. The aim of this study was to determine the number of geriatric medication-related hospitalizations in the Finnish patient population and to discover the potential means of recognizing patients particularly at risk of ADEs. The study was conducted retrospectively from the 2014 emergency department patient records in Oulu University Hospital...

Anaplastic thyroid cancer (ATC) is a rare malignancy that progresses extremely aggressively and often results in dismal prognosis. We investigated the efficacy of inhibiting the activated RAS/RAF/MEK pathway in ATC cells aiming to clarify the mechanism of effect and resistance. Four human ATC cell lines (ACT-1, OCUT-2, OCUT-4 and OCUT-6) were used. OCUT-4 had a BRAF mutation. OCUT-2 had both BRAF and PI3KCA mutations. ACT-1 and OCUT-6 had wild-type BRAF and NRAS mutations. The effects of dabrafenib, a selective inhibitor of the BRAFV600E kinase, and trametinib, a reversible inhibitor of MEK activity, were investigated...

Elevated hydrostatic pressure was used to probe conformational changes of Aquifex aeolicus dihydroorotase (DHO) which catalyzes the third step in de novo pyrimidine biosynthesisis. The isolated protein, a 45 kDa monomer, lacks catalytic activity but becomes active upon formation of a dodecameric complex with aspartate transcarbamoylase (ATC). X-ray crystallographic studies of the isolated DHO and of the complex showed that association induces several major conformational changes in the DHO structure. In the isolated DHO, a flexible loop occludes the active site blocking the access of substrates...

Thyroid cancer is the most common endocrine malignancy. Differentiated thyroid cancer (DTC) with the two subtypes, papillary thyroid cancer (PTC) and follicular thyroid cancer (FTC), is the most frequent subtype of thyroid cancer; more rare subtypes are medullary thyroid cancer (MTC) and anaplastic thyroid cancer (ATC). The incidence of DTC has increased rapidly in recent years due to the more frequent use of imaging methods such as ultrasound of the neck and fine-needle aspiration (FNA) of thyroid nodules...

MOTIVATION: Given a compound, can we predict which ATC (Anatomical Therapeutic Chemical) class/classes it belongs to? It is a challenging problem since the information thus obtained can be used to deduce its possible active ingredients, as well as its therapeutic, pharmacological and chemical properties. And hence the pace of drug development could be substantially expedited. But this problem is by no means an easy one. Particularly, some drugs or compounds may belong to two or more ATC classes...

The rising number of colorectal cancer (CRC) survivors is likely to impose a burden on healthcare systems. Effective resource allocation between primary and hospital care to ensure ongoing high-quality care is under discussion. Therefore, it is important to understand the current role of GPs during follow-up care of CRC. This study explores the primary healthcare use of patients 2-6 years after CRC treatment. Annual rates of face-to-face contacts, prescribed medication and referrals were compared between CRC patients and age, gender and GP matched controls in a historical prospective study...

Design concepts and algorithms were developed to address the eye tracking analysis issues that arise when (1) participants interrogate dynamic multielement objects that can overlap on the display and (2) visual angle error of the eye trackers is incapable of providing exact eye fixation coordinates. These issues were addressed by (1) developing dynamic areas of interests (AOIs) in the form of either convex or rectangular shapes to represent the moving and shape-changing multielement objects, (2) introducing the concept of AOI gap tolerance (AGT) that controls the size of the AOIs to address the overlapping and visual angle error issues, and (3) finding a near optimal AGT value...

Nuclear magnetic resonance (NMR) spectroscopy has been established as a potent method for the determination of foldamer structures in solution. However, the NMR techniques could be limited by averaging, so additional experimental techniques are often needed to fully endorse the folding properties of a sequence. We have recently demonstrated that oligo-γ-peptides composed of 4-amino(methyl)-1,3-thiazole-5-carboxylic acids (ATCs) adopt an original helical fold stabilized by hydrogen bonds forming C9 pseudocycles...

In this study, we determined the whole mitochondrial genome profile of the three-spot swimming crab (Portunus sanguinolentus) and elucidated phylogenetic relationships between representative species in the order Decapoda. The mitochondrial genome was 16,024 bp in length and consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a putative control region. Of the 37 genes, 23 were encoded by the heavy strand while 14 were encoded by the light strand. Four types of start codons were identified; ATG initiated nine genes, ATT initiated two genes, and ATC and GTG each started one gene...

Anaplastic thyroid cancer (ATC) is an aggressive uncommon malignancy with limited treatment. Traditional antineoplastic chemotherapy has not been successful in the management of metastatic ATC. As a result, the focus has shifted to the development of novel therapies for this disease. The availability of economical comprehensive genomic profiling (CGP) platforms with rapid turn-around to identify molecular aberrations in tumors that are potential therapeutic targets has increasingly changed the face of cancer therapy...

Long non-coding RNAs (lncRNAs) are important for transcription and for epigenetic or posttranscriptional regulation of gene expression and may contribute to carcinogenesis. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), an lncRNA involved in the regulation of the cell cycle, cell proliferation, and cell migration, is known to be deregulated in multiple cancers. Here, we analyzed the expression of MALAT1 on 195 cases of benign and malignant thyroid neoplasms by using tissue microarrays for RNA in situ hybridization (ISH) and real-time PCR...

Anaplastic thyroid carcinoma (ATC) is the most aggressive thyroid cancer with a median survival of 4-6 months. Identification of mutations contributing to aberrant activation of signaling cascades in ATC may provide novel opportunities for targeted therapy. Thirty-nine ATC samples were studied by next-generation sequencing (NGS) with an established gene panel. High quality readout was obtained in 30/39 ATC. Twenty-eight ATC harbored a mutation in at least one of the studied genes: TP53 (18/30), NF1 (11/30), ALK (6/30), NRAS (4/30), ATRX (3/30), BRAF (2/30), HRAS (2/30), KRAS (1/30)...
