Introgression of Herbicide-Resistant Gene from Genetically Modified L. to through Backcrossing.

Interspecific hybridization between two different Brassicaceae species, namely ssp. (♀) (AA, 2n = 2x = 20) and genetically modified (♂) (AACC, 2n = 4x = 38), was performed to study the transmission of a herbicide resistance gene from a tetraploid to a diploid species. Initially, four different GM lines were used for hybridization with via hand pollination.

Lyoprotectant Constituents Suited for Lyophilization and Reconstitution of Stem-Cell-Derived Extracellular Vesicles.

Stem-cell-derived extracellular vesicles (EVs) are emerging as an alternative approach to stem cell therapy. Successful lyophilization of EVs could enable convenient storage and distribution of EV medicinal products at room temperature for long periods, thus considerably increasing the accessibility of EV therapeutics to patients. In this study, we aimed to identify an appropriate lyoprotectant composition for the lyophilization and reconstitution of stem-cell-derived EVs.

Mesenchymal Stem Cell-Extracellular Vesicle Therapy for Stroke: Scalable Production and Imaging Biomarker Studies.

A major clinical hurdle to translate MSC-derived extracellular vesicles (EVs) is the lack of a method to scale-up the production of EVs with customized therapeutic properties. In this study, we tested whether EV production by a scalable 3D-bioprocessing method is feasible and improves neuroplasticity in animal models of stroke using MRI study. MSCs were cultured in a 3D-spheroid using a micro-patterned well.

Initially, six subspecies of were hybridized with GM through hand pollination.

Interspecific Hybridization of Transgenic and -An Overview.

In nature, interspecific hybridization occurs frequently and can contribute to the production of new species or the introgression of beneficial adaptive features between species. It has great potential in agricultural systems to boost the process of targeted crop improvement. In the advent of genetically modified (GM) crops, it has a disadvantage that it involves the transgene escaping to unintended plants, which could result in non-specific weedy crops.

Discrimination of Transgenic Canola ( L.) and their Hybrids with using Vis-NIR Spectroscopy and Machine Learning Methods.

In recent years, the rapid development of genetically modified (GM) technology has raised concerns about the safety of GM crops and foods for human health and the ecological environment. Gene flow from GM crops to other crops, especially in the Brassicaceae family, might pose a threat to the environment due to their weediness. Hence, finding reliable, quick, and low-cost methods to detect and monitor the presence of GM crops and crop products is important.

An Overview of Near Infrared Spectroscopy and Its Applications in the Detection of Genetically Modified Organisms.

Near-infrared spectroscopy (NIRS) has become a more popular approach for quantitative and qualitative analysis of feeds, foods and medicine in conjunction with an arsenal of chemometric tools. This was the foundation for the increased importance of NIRS in other fields, like genetics and transgenic monitoring. A considerable number of studies have utilized NIRS for the effective identification and discrimination of plants and foods, especially for the identification of genetically modified crops.

B Cell-Based Vaccine Transduced With ESAT6-Expressing Vaccinia Virus and Presenting α-Galactosylceramide Is a Novel Vaccine Candidate Against ESAT6-Expressing Mycobacterial Diseases.

Early secretory antigenic target-6 (ESAT6) is a potent immunogenic antigen expressed in as well as in some non-tuberculous mycobacteria (NTM), such as . is one of the most clinically relevant species of NTM that causes mycobacterial lung disease, which is clinically indistinguishable from tuberculosis. In the current study, we designed a novel cell-based vaccine using B cells that were transduced with vaccinia virus expressing ESAT6 (vacESAT6), and presenting α-galactosylceramide (αGC), a ligand of invariant NKT cells.

Horse-riding accidents and injuries in historical records of Joseon Dynasty, Korea.

Only a few osteological reports describe bone injuries thought to have been caused by falls from horses. Nevertheless, anthropological study alone is insufficient for establishing the correlates of such equestrian accidents. We therefore reviewed the records in Seungjeongwon ilgi (Diaries of the Royal Secretariat) and Joseon wangjo silrok (Annals of the Joseon Dynasty) of the Korea's Joseon period (1392-1910 CE).

Efficient scalable production of therapeutic microvesicles derived from human mesenchymal stem cells.

Microvesicles (MVs) released by cells are involved in a multitude of physiological events as important mediators of intercellular communication. MVs derived from mesenchymal stem cells (MSCs) contain various paracrine factors from the cells that primarily contribute to their therapeutic efficacy observed in numerous clinical trials. As nano-sized and bi-lipid layered vesicles retaining therapeutic potency equivalent to that of MSCs, MSC-derived MVs have been in focus as ideal medicinal candidates for regenerative medicine, and are preferred over MSC infusion therapy with their improved safety profiles.

Is WHODAS 2.0 Useful for Colorectal Cancer Survivors?

Objective: To compare the disability level of colorectal cancer survivors with and without stoma by using the Korean version of the 12-item, interview-administered World Health Organization Disability Assessment Schedule 2.0 (Korean version of WHODAS 2.0).

A novel cylindrical microwell featuring inverted-pyramidal opening for efficient cell spheroid formation without cell loss.

Spheroid cultures have been often used to simulate and understand in situ biological occurrences with potential to be further applied to therapeutic approaches, such as cell transplantation. However, traditional lab-scale techniques hardly reached the needed large scale production of cell spheroids, thus limiting their versatility in many biomedical fields. Microscale technologies have rapidly improved in the last decade, and contributed to the large scale production of cell spheroids with high controllability and reproducibility.

Methods: Items were generated from the brief ICF core set for breast cancer and in-depth interviews from eight oncologists. Psychometric properties were evaluated in 158 female Korean patients with breast cancer using Rasch analysis, such as fit of the ICF categories, targeting between the ICF categories and a person's abilities, unidimensionality, and reliability.

Oestrogen up-regulates interleukin-21 production by CD4(+) T lymphocytes in patients with systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease in which abnormal immune responses are mediated by tissue-binding autoantibodies and immune complex deposition. Because most SLE patients are women of child-bearing age, oestrogen has been suggested to play an important role in SLE pathogenesis. One proposed role is to induce B-cell activation, culminating in increased autoantibody production.

Ethyl pyruvate ameliorates albuminuria and glomerular injury in the animal model of diabetic nephropathy.

Pyruvate is an endogenous antioxidant and anti-inflammatory substance. The present study was implemented to investigate the protective effect of ethyl pyruvate (EP) against the development and progression of diabetic nephropathy in an in vivo and in vitro model. Diabetic rats were prepared by injecting streptozotocin (65 mg/kg).

Immunocytochemical staining of p16(ink4a) protein as an adjunct test in equivocal liquid-based cytology.

For cervical cancer screening, HPV-DNA test is expensive and is not easily available in all clinical situations. Thus, we investigated the role of p16(ink4a) immunostaining as another adjunct test to diagnose cervical neoplasia in equivocal liquid based cytology. Eighty-seven patients were randomly selected for this study (3 patients with normal, 84 patients with abnormal including 24 ASCUS, 30 LSIL, and 30 HSIL).

Heterogeneous rRNAs are differentially expressed during the morphological development of Streptomyces coelicolor.

It is generally assumed that all mature rRNA molecules assembled into ribosomes within a single cell are identical. However, sequence analysis of Streptomyces coelicolor genome revealed that it harbors six copies of divergent rRNA operons that may express and constitute three and five different kinds of small subunit (SSU) and large subunit (LSU) rRNA molecules, respectively, in a single cell. Phylogenetic analyses of the LSU rRNA genes and the internal transcribed spacer between SSU and LSU genes indicated that the LSU gene of rrnA and rrnE operons might be the result of interspecies recombination between rRNA genes in closely related streptomycetes.
