Visual speech cues play an important role in speech recognition, and the McGurk effect is a classic demonstration of this. In the original McGurk & Macdonald (Nature 264, 746-748 1976) experiment, 98% of participants reported an illusory "fusion" percept of /d/ when listening to the spoken syllable /b/ and watching the visual speech movements for /g/. However, more recent work shows that subject and task differences influence the proportion of fusion responses. In the current study, we varied task (forced-choice vs. open-ended), stimulus set (including /d/ exemplars vs. not), and data collection environment (lab vs. Mechanical Turk) to investigate the robustness of the McGurk effect. Across experiments, using the same stimuli to elicit the McGurk effect, we found fusion responses ranging from 10% to 60%, thus showing large variability in the likelihood of experiencing the McGurk effect across factors that are unrelated to the perceptual information provided by the stimuli. Rather than a robust perceptual illusion, we therefore argue that the McGurk effect exists only for some individuals under specific task situations.Significance This series of studies re-evaluates the classic McGurk effect, which shows the relevance of visual cues on speech perception. We highlight the importance of taking into account subject variables and task differences, and challenge future researchers to think carefully about the perceptual basis of the McGurk effect, how it is defined, and what it can tell us about audiovisual integration in speech.

Currently, Tigers (the top predator of an ecosystem) are on the list of endangered species. Thus the need is to understand the tiger's population genomics to design their conservation strategies.

We analyzed the molecular evolution of tiger diversity using NADH dehydrogenase subunit 4 (ND4), a significant electron transport chain component.

We have analyzed nucleotide composition and distribution pattern of ND genes, molecular evolution, evolutionary conservation pattern and conserved blocks of NADH, phylogenomics of ND4, and estimating species divergence, etc., using different bioinformatics tools and software, and MATLAB programming and computing environment.

The nucleotide composition and distribution pattern of ND genes in the tiger genome demonstrated an increase in the number of adenine (A) and a lower trend of A+T content in some place of the distribution analysis. However, the observed distributions were not significant (P > 0.05). Evolutionary conservation analysis showed three highly align blocks (186 to 198, 406 to 416, and 527 to 545). On mapping the molecular evolution of ND4 among model species (n = 30), we observed its presence in a broader range of species. ND4 based molecular evolution of tiger diversity and time divergence for a tiger (20 different other species) shows that genus Panthera originated more or less at a similar time.

The nucleotide composition and nucleotide distribution pattern of tiger ND genes showed the evolutionary pattern and origin of tiger and Panthera lineage concerning the molecular clock, which will help to understand their adaptive evolution.

Human papillomaviruses (HPV) are known to play a central etiological role in the development of cervical cancer. General HPV genotyping methods consist of PCR with consensus primers combined with various detection methods.

The aim was to develop HPV L1 DNA reference materials to evaluate the sensitivity, specificity, and accuracy of genotyping results obtained from the HPV DNA Genotyping Chip (HPV CHIP) and RFMP assays.

In this study, the Ministry of Food and Drug Safety (MFDS) established reference DNA materials for the L1 gene from 41 subtypes of anogenital HPV to aid in genotyping human papillomavirus (HPV) strains. selleck screening library Of these, 22 subtypes were obtained from cervical scrape samples of Korean women and 19 subtypes were synthesized. These reference materials include 13 high-risk types (HPV-16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68), 3 probable high-risk types (HPV-26, 53, and 66), 16 low-risk types (HPV-6, 10, 11, 27, 34, 40, 42, 43, 44, 54, 55, 61, 70, 72, 73, and 81), and 8 undetermined-risk types (HPV-3, 57, 62, 67, 69, 71, 74, and 84). After confirming the sequences by standard methods, these HPV L1 DNA reference materials were then used to compare results from the HPV DNA Genotyping Chip (HPV CHIP) and restriction fragment mass polymorphism (RFMP) assays.

Data collected from the HPV CHIP and RFMP assay showed comparably high sensitivity and accuracy. Both assays could detect 10

or more copies/μl of HPV L1 DNA from 39 types of HPV, with higher accuracy in detecting samples with mixed types of HPV.

The present study confirms the HPV L1 DNA reference materials developed by MFDS are reliable and useful for the evaluation of HPV genotyping assays.

Paeonia ostii seeds were identified as novel sources of edible plant oil with a high proportion of α-linolenic acid, a type of n-3 fatty acid with many health benefits. Due to the unreliability of seed oil content and quality, it is necessary to discover the mechanism underlying lipid biosynthesis in Paeonia ostii seeds.

This study aimed to identify the key genes involved in lipid biosynthesis in Paeonia ostii seeds by analyzing the relationship among the seed characteristics and the expression patterns of lipid genes in Paeonia ostii during seed development.

Preliminary research on Paeonia ostii seed development was carried out from 10days after pollination until maturity, focusing on phenology, oil content and lipid profiles. In addition, we investigated the spatiotemporal expression of 36 lipid biosynthetic genes in Paeonia ostii by using quantitative real-time PCR.

The results suggested that the development of Paeonia ostii seeds from pollination to maturity could be divided into three periods. The 36 lipid genes showed various spatiotemporal expression patterns and five gene groups with distinct temporal patterns during seed development were identified by clustering analysis of expression data.
