Brain metastases (BMs) reflect an area of high clinical need, as up to 40% of patients with metastatic cancer will develop this morbid and highly fatal complication. Historically, treatment strategies have relied on local approaches including radiosurgery, whole-brain radiotherapy, and neurosurgical resection. Recently, targeted and immune-modulating therapies have shown promising responses and have been introduced in the clinical management of patients with BMs. Recent improvements in genomic technologies have enriched our understanding of BMs and have demonstrated that BMs present with significant genetic divergence from the originating primary tumor, such that potentially targetable genetic alterations are detected only in the BMs...

Immunotherapy targeting the programmed cell death-1/programmed death ligand 1(PD-L1) pathway has shown promising antitumor activity in brain metastases (BMs) of non-small cell lung cancer (NSCLC) patients with an acceptable safety profile; however, the response rates often differ between primary lesions and intracranial lesions. Studies are necessary to identify detailed characterizations of the response biomarkers. In this study, we aimed to compare the differences of PD-L1 expression and CD8+ tumor-infiltrating lymphocyte (TIL) density, two major response biomarkers of PD-1/PD-L1 blockade, between paired primary and brain metastatic lesions in advanced NSCLC...

A wide variety of pathogenic agents such as bacteria, viruses and parasites can be greatly concentrated in filter feeding bivalve molluscan shellfish (BMS), that are grown in faecally contaminated waters. Human health risks associated with the consumption of BMS are also compounded by the traditional pattern of consuming them raw or lightly cooked. Because of these well-established food safety risks, food legislation such as that in Europe stipulates that BMS production areas are monitored for faecal contamination and classified accordingly...

Sickle cell disease patients are at increased risk of developing a chronic kidney disease. Endothelial dysfunction and inflammation associated with hemolysis lead to vasculopathy and contribute to the development of renal disease. Here we used a Townes sickle cell disease mouse model to examine renal endothelial injury. Renal disease in Townes mice was associated with glomerular hypertrophy, capillary dilation and congestion, and significant endothelial injury. We also detected substantial renal macrophage infiltration, and accumulation of macrophage stimulating protein 1 in glomerular capillary...

Rabbit mesenchymal stem cells (MSCs) are important seed cells in regenerative medicine research, particularly in translational research. In the current study, we showed that rabbit subchondral bone is a reliable source of MSCs. First, we harvested subchondral bone (SCB) from the rabbit knee-joint and initiated the MSC culture by cultivating enzyme-treated SCB. Adherent fibroblast-like cells that outgrew from SCB fulfill the common immuno-phenotypic criteria for defining MSCs, but with low contamination of CD45+ hematopoietic cells...

Burning mouth syndrome (BMS) is a chronic pain condition characterised by a persistent burning sensation in clinically normal oral mucosa. BMS most commonly occurs in middleaged and elderly women. Various local and systemic factors can cause oral burning symptoms. When all possible local and systemic factors are excluded, burning mouth symptoms can be diagnosed as BMS. Psychophysical tests and histopathological data suggest the involvement of peripheral and central neuropathic mechanisms in BMS etiopathogenesis...

Bent metallocenes (BM) have anti-tumor properties but they face a serious drug efficacy problem due to poor aqueous solubility and rapid hydrolysis under physiological conditions. These two problems can be fixed by encapsulating them in host molecules such as cyclodextrin (CD), cucurbituril (CB) etc. Experimentally, CD-BM, CB-BM host-guest complexes have been investigated to check the efficiency of the drug delivery and efficiency of the encapsulated drug. CB has been reported to be a better host than CD but the reasons for this has not been figured out...

Indoleamine 2,3-dioxygenase 1 (IDO1) is overexpressed by cancer cells and the antigen presenting dendritic cells in the tumor microenvironment (TME). Activation of IDO1 depletes tryptophan and produces kynurenine, which induces T cell anergy and suppresses tumor control by the immune system. When combined with an immune checkpoint inhibitor, IDO1 inhibitors have shown promising anticancer activity in preclinical tumor models as well as in early stage clinical trials. Areas covered: IDO1 inhibitors disclosed in the patent literature from 2013-2017 are categorized, when applicable, according to their structural similarity to the clinical development candidates indoximod and PF-06840003, navoximod, epacadostat, KHK2455 and aryl-1,2-diamines, and BMS-986205 among others, respectively...

To compare the results of psychometric tests in patients with BMS and controls, participants were tested for depression, anxiety, fatigue and distress. Patients with BMS had noticeably higher scores for depression, fatigue and distress, compared to controls. Depression and distress were significantly correlated with the burning symptom. Moreover, distress and burning symptoms proved to be interdependent. Depression seems to play a specific role in BMS. Burning symptoms affect quality of life of patients and they could be a predictor of distress...

Mitochondrial ATP-regulated potassium channels are present in the inner membrane of the mitochondria of various cells. In the present study, we show for the first time mitochondrial ATP-regulated potassium channels in human dermal fibroblast cells. Using the patch-clamp technique on the inner mitochondrial membrane of fibroblasts, we detected a potassium channel with a mean conductance equal to 100 pS in symmetric 150 mM KCl. The activity of this channel was inhibited by a complex of ATP/Mg2+ and activated by potassium channel openers such as diazoxide or BMS 191095...
