PURPOSE: To identify prognostic factors that may predict the amount of long-term visual improvement after idiopathic epiretinal membrane removal. METHODS: A retrospective study of 114 patients who underwent epiretinal membrane removal was performed. The central foveal thickness, inner retinal layer thickness, inner retinal irregularity index, length of the cone outer segment tip line defect, and length of the ellipsoid zone defect were measured. The optical coherence tomography parameters that were associated with the amount of visual improvement were determined at 24 months postoperatively...

The degrading influence of noise on various critical bands of speech was assessed. A modified version of the compound method [Apoux and Healy (2012) J. Acoust. Soc. Am. 132, 1078-1087] was employed to establish this noise susceptibility for each speech band. Noise was added to the target speech band at various signal-to-noise ratios to determine the amount of noise required to reduce the contribution of that band by 50%. It was found that noise susceptibility is not equal across the speech spectrum, as is commonly assumed and incorporated into modern indexes...

Most of sturgeon species (Acipenseridae) are currently critically endangered. Attempts to revive these populations include artificial breeding in hatcheries. However, under artificial reproduction, sturgeon embryos occasionally develop atypically, showing 3, 5, 6, 7, 9, or 10 cells at the 2- to 4-cell stage. This study was undertaken with the objective of understanding the mechanism of the atypical division (AD) in embryos during artificial breeding. Using several sturgeon species, we tested two hypotheses: 1) polyspermy and 2) retention of the second polar body...

Selenium (Se), a sparse element on earth, is an essential micronutrient in the vertebrate diet and its intake depends on its content in soils and waters worldwide. Selenium is required due to its function in selenoproteins, which contain selenocysteine (Sec), the 21st amino acid in the genetic code, as one of their constituent residues. Selenocysteine is analogous to the amino acid cysteine (Cys), which uses the abounding element sulfur instead. Despite the irregular distribution of Se worldwide, its distinct biochemical properties have made the substitution of Sec for Cys rare in vertebrate proteins...

Immunohistochemistry is a basic routine in establishing the diagnosis of many tumors. However, immunomarkers are often irregularly distributed across different regions of the same tumor, alternating positive and negative areas without any apparent cause. Full identification of this type of intratumor heterogeneity is crucial for patients since the expression of many markers is linked to the prognosis and/or treatment of some tumors. We have quantified this variability testing 406 tumor samples from eight clear cell renal cell carcinomas using four epithelial-mesenchymal transition markers (vimentin, ZEB-1, β-catenin, and E-cadherin) and two different sampling protocols...

Innovative dual detection methods for mercury(II) ions (Hg(II) ) have been developed based on the formation of gold nanostructures (AuNSs) following the addition of mercury-containing solution to a mixture containing an optimized amount of Au(III) , H2 O2 , HCl, and silver nanoparticles (AgNPs). In the absence of Hg(II) , the addition of Au(III) , H2 O2 , and HCl to the AgNP solution changes the solution's color from yellow to red, and the absorption peak shifts from 400 to 526nm, indicating the dissolution of AgNPs and the formation of gold nanoparticles (AuNPs)...

We report a case of minimal deviation adenocarcinoma (MDA) of the uterine cervix showing varicolored cytopathologic features on Papanicolaou (Pap) smear, which may indicate features suggestive of lobular endocervical glandular hyperplasia (LEGH)-adenocarcinoma sequence. A 57-year-old woman presented with a profuse amount of watery vaginal discharge. Gynecological examination revealed a cervical mass with involvement of the right parametrium. Conventional Pap smear showed hypercellularity consisting of approximately 4 types of clusters as follows: (1) clusters showing a monolayered honeycomb sheet of endocervical cells with golden-yellow mucin and bland nuclei, (2) three-dimensional clusters showing varicolored mucin and irregular nuclear overlapping, (3) irregularly shaped clusters showing distorted chicken-wire-mesh appearance with noticeable protrusions of the nuclei and clear or faint varicolored cytoplasm, and (4) crowded clusters showing scarce mucin and nuclear atypia...

Effusion-based lymphoma (EBL) is a rare but distinct entity of large B-cell lymphoma in effusion without association with human herpes virus-8 (HHV-8). Spontaneous regression after pleurocentesis has been observed; but to our knowledge, there are no reports on the morphological and molecular features of subsequent aspirations in regressing cases. Here, we report the case of a 92-year-old male with chronic obstructive pulmonary disease, who presented with right pleural effusion. He had no human immunodeficiency virus, hepatitis B virus, or hepatitis C virus infection, and CT scans revealed no mass lesion...
