lacenta accompanied by the PI3K-AKT-mTOR signaling inhibition, which suggests that ART may affect the function of placenta amino acid transporter during the late pregnancy, leading to enlarged placentas and probably low birth weight.Long non coding RNAs (lncRNAs) are involved in the tumor growth, invasion, metastasis, and cancer recurrence. The improper expression of certain lncRNAs is correlated with the prognosis of the cancer patients. LncRNA single nucleotide polymorphisms (SNPs) largely affect the expression, structure, and function of lncRNAs. Therefore, they affect cancer prognosis and susceptibility. In the present review, we tried to collect all published papers on the prognostic ability in cancer considering the correlation of different lncRNAs polymorphism and survival. We explored the association between lncRNA (i.e. MALAT1, ANRIL, GAS5, TP73-AS1, HOTAIR, H19, LncARSR, PVT1, HOTTIP, PRNCR1, PCAT1, CASC8, UCA1, SNHG5, PARP1, Linc00312, and NEAT) polymorphisms with cancer prognosis. The HOTAIR rs920778/rs4759314 and MALAT1 rs664589 polymorphisms play an important role in cancer relevant functions. Other lncRNAs polymorphisms are special for certain kinds of cancer, indicating their function in specific signaling pathways. Accordingly, the individual or combined genotypes of lncRNA polymorphisms are able to predict cancer prognosis. However, most of the samples are Chinese and do not represent the global population. More large-scale trials of different ethnic groups as well as comprehensive health records are therefore needed for more validation of the results.Mucinous (secretory) myoepithelioma is a very uncommon variant of myoepithelioma characterized by the presence of intracellular mucin. We herein report the findings of a 51-year-old woman who presented with a mass in the right parotid region, which had been slowly growing over the previous year. Magnetic resonance imaging revealed a rounded mass with lobulated margins in the tail of the right parotid gland that showed heterogeneous uptake in the anterior margin of the mass. A clinical diagnosis of pleomorphic adenoma was made. Superficial parotidectomy revealed a 3.6 cm encapsulated, round-shaped, light brown, gelatinous, solid tumor. The neoplasm showed a reticular pattern forming pseudoglandular structures that were filled with abundant extracellular mucin secretion. Additionally, lakes of mucin of different sizes appeared to be scattered throughout the neoplasm. The epithelioid tumor cells were medium-sized with eosinophilic cytoplasm, centrally located, small, uniform nuclei, and inconspicuous nucleoli. Mitoses were not observed. Signet-ring or univacuolated cells, ductal, and glandular components were absent. The extracellular mucin was positive for mucicarmine and Alcian blue staining. Immunohistochemical staining revealed that the tumor cells were diffusely and strongly positive for S100 protein, cytokeratin AE1/AE3, SOX10, and DOG-1. Occasional compact solid clusters of epithelioid cells showed intense positivity for CK7 and high-molecular-weight CK. The diagnosis was pure extracellular mucin-producing (colloid) myoepithelioma. To our knowledge, this type of neoplasm has not been previously published. Knowledge of this new variant will avoid diagnostic difficulties.Tumour cells develop by accumulating changes in the genome that result in changes of main cellular processes. Aberrations of basic processes such as replication and chromatin reassembly are particularly important for genomic (in)stability. The aim of this study was to analyse the expression of genes whose products are crucial for the regulation of replication and chromatin reassembly during lymphomagenesis (DNMT1, PCNA, MCM2, CDT1, EZH2, GMNN, EP300). Non-tumour B cells were used as a control, and follicular lymphoma (FL) and the two most common groups of diffuse large B cell lymphoma (DLBCL) samples were used as a model for tumour progression. The results showed that there are significant changes in the expression of the analysed genes in lymphomagenesis, but also that these changes do not display linearity when assessed in relation to the degree of tumour aggression. Additionally, an integrated bioinformatics analysis of the difference in the expression of selected genes between tumour and non-tumour samples, and between tumour samples (FL vs. DLBCL) in five GEO datasets, did not show a consistent pattern of difference among the datasets.
To compare the dosimetric parameters and radiogenic risks from 3D-CRT, IMRT and VMAT for flank irradiation due to pediatric Wilms tumor.

Two computational XCAT phantoms simulating an average 5- and 10-year-old patient were used. Four different planning target volumes (PTVs) for right flank (RF) and left flank (LF) irradiation with or without paraaortic lymph nodes (LNs) and eight surrounding organs-at-risk (OARs) were contoured on the phantoms' CT sections. Forty-eight 3D-CRT, IMRT and VMAT plans were created using 6 and 10-MV photons on the two phantoms. The target coverage index (TCI), homogeneity index (HI), conformity index (CI), conformation number (CN) and OAR exposure were determined through dose-volume histogram (DVH) analysis. Second cancer risks were estimated using a non-linear model and DVH data.

The IMRT and VMAT for LF+LN and RF+LN irradiation reduced the radiation dose to four to six out of the eight OARs compared to 3D-CRT. Conventional treatment provided a better organ sparing for RF anage and target site.
Non-steroidal anti-inflammatory drugs-exacerbated respiratory disease (NERD), intrinsic asthma, eosinophilic granulomatosis with polyangiitis (EGPA) and odontogenic sinusitis may be associated with nasal polyps. The aim of the study was to compare circulating inflammatory cells and structural histopathology of these groups of nasal polyposis.

We retrospectively evaluated 71 patients with nasal polyps stratified according to the above-mentioned pathogenesis. All patients underwent preoperative laboratory investigations and primary endoscopic sinus surgery. Surgical specimens were submitted to structured histopathological evaluation.

The median tissue eosinophil count (cells/HPF) was significantly different between the considered groups of nasal polyposis (p=0.0004). The median of NERD sub-cohort was significantly higher than intrinsic asthma (p=0.0030), odontogenic CRS (p=0.0001) and EGPA ones (p=0.0094). Eosinophilic aggregates positive rate was significantly higher in NERD sub-cohort than in odontogeniecognition of rational therapeutic and follow-up approaches that consider the tissue modifications associated with the response to drugs and surgery.
The goal of this research study was to measure changes in the quality of life (QoL) of adults with profound intellectual and multiple disabilities (PIMD) and complex care needs following their transition from a large institutional residence to smaller community homes in Central Canada.

A pre- post-transition quasi-experimental time-series longitudinal study design was implemented to measure the impact of community transition on the QoL of study participants. QoL was assessed in eight domains (self-determination; emotional, physical, and material wellbeing; rights; personal development; social inclusion; and interpersonal relations) by proxy at two time points (Time 1 pre-transition and Time 2 at least 6 months post-transition) using the standardized tool San Martin Scale. The study group included 33 persons with PIMD and complex care needs (20 men [60%] and 13 women [40%]) aged 24-55 years (M = 42.52; SD = 8.07). PI3K inhibitor Paired-samples t-test was conducted to determine significant changes in the QoL of study participants following their community transition.

Between pre- and post-transition, study participants experienced significant improvements in all the eight domains of QoL evaluated as well as in global QoL. Mean differences ranged from 5.67 (SD = 5.16, t
=6.31, p=.001) for rights to 1.73 (SD = 3.10, t
=3.19, p=.003) for physical wellbeing. Mean global QoL improved significantly from 99.97 (SD = 16.54) pre-transition to 120.42 (SD = 10.54) post-transition (M
= 17.55, t
=6.69, p=.001).

This longitudinal study provides evidence of improved QoL for persons with PIMD following deinstitutionalization.

The aims of this study were 1) quantifying twelve CECs (including pharmaceutical, stimulant, and artificial sweetener compounds) in both untreated and treated wastewater samples in a Brazilian wastewater treatment plant (WWTP) using bidimensional liquid chromatography coupled with tandem mass spectrometry, allowing the selection of five marker (i.e., priority) CECs; 2) evaluating the adsorption potential of such selected CECs [caffeine, hydrochlorothiazide, saccharin, sucralose (SUC), and sulfamethoxazole (SMX)] onto coconut-shell granular activated carbon (GAC); and 3) investigating the removal of the same CECs by a multi-barrier system (pilot-scale, 350 L h-1) treating the effluent of the WWTP and composed of reverse osmosisrmance requirements, the RO + UV/H2O2+GAC system showed promising results as a first approach to direct potable reuse of water.Shrimp farming wastewater includes high amounts of phosphate and microbiological contaminants, necessitating further treatment before release into receiving water bodies. After 24 h of shrimp wastewater treatment, alginate beads containing the blue-green algal Synechocystis strain lacking the phosphate regulator gene (mutant strain ΔSphU) at 150 mg L-1 reduced phosphate content from 17.5 mg L-1 to 5.0 mg L-1, representing 71.5% removal efficiency, with phosphate removal rate reaching 6.9 mg gDW-1 h-1 during photobioreactor operation. For short-term treatment, removal rates of nitrate, ammonium and nitrite were 42.7, 48.5 and 92.9%, respectively. Microalgal encapsulated beads also impacted the bacterial community composition dynamics in shrimp wastewater. Next-generation sequencing targeting the V3-V4 region of the 16S rDNA gene showed significant differences in bacterial community composition after 24 h of treatment. Proteobacteria are the most abundant phylum in shrimp wastewater. After 24 h of bioremediation, reductions of harmful bacteria in the Cellvibrionaceae and Pseudomonadaceae families were recorded at 5.85 and 3.18%, respectively. Engineered microalgal immobilization under optimal conditions can be applied as an alternative short-term bioremediation strategy to remove phosphate and other harmful microbial contamination from shrimp farming wastewater.Over-compensatory growth of plants after disturbance is generally preferred by grassland users and managers because of more forage. How the grassland productivity and the plant growth condition before disturbance affect the compensatory growth are important for grazing management and the understanding of grassland degradation, yet they are not well understood. A clipping experiment was conducted on the Qinghai-Tibetan Plateau to understand the compensatory growth and conditions for the occurrence of over-compensatory at alpine meadows with different degradation status. Results showed the competition for light constrains the plant growth post-clipping at non-degraded and slightly degraded alpine meadows, while the reduction of soil nitrogen limits it at heavily degraded alpine meadow. The biomass accumulated post-clipping was positively correlated with the growing season biomass in unclipped plots and the biomass at clipping in clipped plots. When the aboveground biomass at clipping was less than 40.10 g m-2 and the growing season biomass was between 38 and 97 g m-2, the over-compensatory growth of alpine meadow could occur.
