Such studies have emphasized the current challenges of MSC-based therapies. find more Treatment efficacy could be enhanced if the limitations were better understood and potentially resolved. This review will summarize some of the strategies by which MSCs have been utilized for ischemic disease treatment, and will highlight some challenges of those applications as well as suggesting some strategies to improve treatment efficacy.The authors suggest introducing the concept "psychological media competence" into psychological terminology. It has become necessary because of the new demands on the professional abilities of an educational psychologist in the new conditions when human development and education are greatly mediated by the new digital media the Internet and TV. The article stresses the importance of diagnosing the professional competence of a psychologist that enables him/her to understand the mechanisms of a personality's formation in a media environment; to define the psychological potential of media content developing or destructive; to regulate media communication which involves children; and to prepare other participants in the educational process teachers, children and their parents for the productive and safe functioning in a media environment. The article presents a comparative analysis of the concepts semantically related to "psychological media competence" "media competence", "psychological competence" "psychological culture" and "media culture" and defines their place in a metalevel model of psychological media competence. The article studies the components of "media competence" and its levels. It also proposes methods of investigating a psychologist's readiness to fulfill his/her functions in a media environment. It shows the necessity of an interdisciplinary approach and integration of propositions of different psychological paradigms to the solution of the tasks of personality development in a media environment. The article presents a theoretical description of "psychological media competence", which, according to the authors, will make it possible to carry out its operationalization, to elaborate programs of development and methods of diagnosing the psychological media competence of participants in the educational process, thus contributing to its effectiveness.Pancreatic undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) is an extremely rare and aggressive malignancy. We report the case of a 71-year-old male who presented with a solid-and-cystic mass in the pancreatic head. The cut section of the pancreaticoduodenectomy specimen showed hemorrhagic polypoid lesions localized to the cyst spaces. Histological examination revealed a cystic background as an intraductal papillary mucinous neoplasm (IPMN) with low-grade dysplasia, while the intra-cystic polypoid mass was morphologically identical to giant cell tumors (GCT) of bone and soft tissue, consisting of a mixture of mononuclear histiocyte-like cells and multinucleated osteoclast-like giant cells. Nuclei of the mononuclear cells were similar to those of the multinucleated giant cells, showing no obvious atypia. The mononuclear cells were diffusely immunoreactive for CD163 and completely negative for all examined epithelial markers. Genetic analysis showed both the IPMN and the GCT-like components harbored identical double mutations of KRAS (G12V) and GNAS (R201C), and confirmed a diagnosis of UC-OGC originating from IPMN. This case emphasized that pancreatic UC-OGC can provide bland morphology, which is morphologically and immunohistochemically undistinguishable from GCT of the bone and soft tissue. Our study also highlights the importance of genetic analyses in properly diagnosing and managing such patients.
Silver nanoparticles (AgNPs) mediated apoptosis is well-known but its rationale is yet to be elucidated. This study explored the mechanistic underpinning of the apoptosis in the Brugia malayi parasitic model.

Silver nanoparticles were synthesized and tested against B. malayi microfilariae (Mf) to explore the role of oxidative and nitrosative stress in its apoptotic effect.

AgNPs caused significant decrease in reduced glutathione (GSH) level and increase in both protein carbonylation and nitric oxide (NO) level indicating oxidative as well as nitrosative stress. Both GSH and nitric oxide synthase (NOS) inhibitors exhibited marked reversal. Nanoparticles and NO-donor in combination but not the NO-donor alone showed significant antiparasitic effect implying the requisite of combined oxidative and nitrosative stress to induce apoptosis. Synthetically prepared peroxynitrite from NaNO
to H
O
showed marked antiparasitic effect in very low dose which could be achieved neither by NaNO
or H
O
alone. GSH reversed the effect of peroxynitrite similar to its specific inhibitor, acetaminophen. GSH also reversed the plummet in mitochondrial oxygen consumption by AgNPs.

We conclude that apoptosis by AgNPs is possibly mediated through peroxynitrite dependent depletion of GSH; this provides a significant insight into the pharmacological as well as toxicological impact of AgNPs.

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. 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.
