Weissella are obligate heterofermentative lactic acid bacteria belonging to the Leuconostocaceae family. Some Weissella can be found in salted and fermented foods, such as kimchi and jeotgal, and plays an important role in the fermentation process. In the present study, for the first time, a rapid and accurate identification method for Weissella species from kimchi and jeotgal was developed based on MALDI-TOF MS, supplemented with an in-house database. Of the 135 Weissella spectra aligned with the MALDI bioTyper database, 56 isolates (41...

The study reports the use of extended gate field-effect transistors (FET) for the label-free and sensitive detection of prostate cancer (PCa) biomarkers in human plasma. The approach integrates for the first time hybrid synthetic receptors comprising of highly selective aptamer-lined pockets (apta-MIP) with FETs for sensitive detection of prostate specific antigen (PSA) at clinically relevant concentrations. The hybrid synthetic receptors were constructed by immobilizing an aptamer-PSA complex on gold and subjecting it to 13 cycles of dopamine electropolymerization...

BACKGROUND: Animal as well as human research indicated that the ventral medial prefrontal cortex (vmPFC) is highly relevant for fear extinction learning. Recently, we showed that targeting the vmPFC with high-frequency repetitive transcranial magnetic stimulation (rTMS) in a placebo-controlled study with 45 healthy controls induced higher prefrontal activity during extinction of conditioned stimuli (CS+) in the active compared to the sham stimulated group and better extinction learning as indicated by ratings, fear potentiated startles and skin conductance responses...

BACKGROUND: Cervical cancer is the fourth most common cancer affecting women worldwide. Despite advances in screening and human papillomavirus (HPV) vaccination, a significant number of women present with or develop advanced disease. Palliative platinum-based chemotherapy (CT) is the standard first-line treatment for metastatic/recurrent cervical cancer. The prognosis remains poor and effective second line options are urgently needed. METHODS: We searched the English-language medical literature as well as relevant guideline databases, published from January 1981 to December 2015 and identified publications related to cervical cancer and its therapies...

Xenotransplantation has vast clinical potential but is limited by the potent immune responses generated against xenogeneic tissue. Immune-privileged Sertoli cells (SCs) survive xenotransplantation long term (90 days) without immunosuppression, making SCs an ideal model to identify xenograft survival mechanisms. Xenograft rejection includes the binding of natural and induced antibodies and the activation of the complement cascade. Using an in vitro cytotoxicity assay, wherein cells were cultured with human serum and complement, we demonstrated that neonatal pig SCs (NPSCs) are resistant to complement-mediated cell lysis and express complement inhibitory factors, membrane cofactor protein (MCP; CD46), and decay-accelerating factor (DAF; CD55) at significantly higher levels than neonatal pig islets (NPIs), which served as non-immune-privileged controls...

Cell therapy has attracted considerable interest as a promising therapeutic alternative for patients with Parkinsons disease (PD). Clinical studies have shown that grafted fetal neural tissue can achieve considerable biochemical and clinical improvements in PD. However, the source of fetal tissue grafts is limited and ethically controversial. Human parthenogenetic stem cells offer a good alternative because they are derived from unfertilized oocytes without destroying potentially viable human embryos and can be used to generate an unlimited supply of neural cells for transplantation...

Retinal and optic nerve diseases are degenerative ocular pathologies which lead to irreversible visual loss. Since the advanced therapies availability, cell-based therapies offer a new all-encompassing approach. Advances in the knowledge of neuroprotection, immunomodulation and regenerative properties of mesenchymal stem cells (MSCs) have been obtained by several preclinical studies of various neurodegenerative diseases. It has provided the opportunity to perform the translation of this knowledge to prospective treatment approaches for clinical practice...

: Seroepidemiology shows that infections with adeno-associated virus (AAV) are widespread, but diverse AAV serotypes isolated from man or non-human primates have so far not been proven as causes of human disease. In view of the increasing success of AAV-derived vectors in human gene therapy, the definition of the in vivo sites of wild-type AAV persistence and clinical consequences of its reactivation are becoming increasingly urgent.Here, we identified the presumed cell-type for AAV persistence in the human host, by highly sensitive AAV PCRs developed for the full spectrum of human AAV serotypes...

: Alpha-5 gamma-aminobutyric acid type A receptors (α5-GABAARs) are located extrasynaptically, regulate neuronal excitability through tonic inhibition, and are fundamentally important for processes such as plasticity and learning. For example, pharmacological blockade of α5-GABAAR in mice with ischemic stroke improved recovery of function by normalizing exaggerated perilesional α5-GABAAR-dependent tonic inhibition. S44819 is a novel competitive selective antagonist of the α5-GABAAR at the GABA-binding site...

Available tyrosine kinase inhibitors for chronic myeloid leukemia bind in an ATP-binding pocket and are affected by evolving mutations that confer resistance. Rebastinib was identified as a switch control inhibitor of BCR-ABL1 and FLT3 and may be active against resistant mutations. A Phase 1, first in human, single-agent study investigated rebastinib in relapsed or refractory chronic or acute myeloid leukemia. Primary objectives were to investigate the safety of rebastinib and establish the maximum tolerated dose (MTD) and recommended Phase 2 dose...

BACKGROUND: Defects in genes involved in mitochondrial fatty-acid oxidation (mFAO) reduce the ability of patients to cope with metabolic challenges. mFAO enzymes accept multiple substrates of different chain length, leading to molecular competition among the substrates. Here, we combined computational modeling with quantitative mouse and patient data to investigate whether substrate competition affects pathway robustness in mFAO disorders. RESULTS: First, we used comprehensive biochemical analyses of wild-type mice and mice deficient for medium-chain acyl-CoA dehydrogenase (MCAD) to parameterize a detailed computational model of mFAO...

Fusarium is a rapidly emerging, multidrug-resistant genus of fungal opportunists that was first identified in 1958 and is presently recognized in numerous cases of fusariosis each year. The authors examined trends in global Fusarium distribution, clinical presentation and prevalence since 1958 with the assumption that their distributions in each region had remained unaltered. The phylogeny and epidemiology of 127 geographically diverse isolates, representing 26 Fusarium species, were evaluated using partial sequences of the RPB2 and TEF1 genes, and compared with AFLP fingerprinting data...
