The aim of this study is to investigate the relationship between the Modic changes (MCs) and sagittal parameters of the cervical spine.We conducted a retrospective review of 100 outpatients with magnetic resonance imaging (MRI) scans of the cervical spine (50 male and 50 female). MRI parameters were measured, including neck tilt, T1 slope (T1 ), thoracic inlet angle (TIA), and cervical lordosis (CL: Cobb C2-7). Patients were divided into 4 groups according to the presence or absence of MC and T1s, respectively: MC(+) and MC(-) groups, as well as H-T1s (T1s ≥25°) and L-T1s subgroups (T1s <25°)...

Neutrophil breach of the mucosal surface is a common pathological consequence of infection. We present an advanced co-culture model to explore neutrophil transepithelial migration utilizing airway mucosal barriers differentiated from primary human airway basal cells and examined by advanced imaging. Human airway basal cells were differentiated and cultured at air-liquid interface (ALI) on the underside of 3 µm pore-sized transwells, compatible with the study of transmigrating neutrophils. Inverted ALIs exhibit beating cilia and mucus production, consistent with conventional ALIs, as visualized by micro-optical coherence tomography (µOCT)...

Based on the structural similarity, herein, nucleoside analogue therapeutics were integrated into DNA strands through conventional solid-phase synthesis. By elaborately designing their sequences, floxuridine-integrated DNA strands were synthesized and self-assembled into well-defined DNA polyhedra with definite drug loading ratio as well as tunable size and morphology. As a novel drug delivery system, these drug-containing DNA polyhedra could ideally mimic the Trojan Horse to deliver chemotherapeutics into tumor cells and fight against cancer...

Animals often learn through observing their conspecifics. However, the mechanisms of them obtaining useful knowledge during observation are beginning to be understood. This protocol describes a novel social observation task to test the 'local enhancement theory', which proposes that presence of social subjects in an environment facilitates one's understanding of the environments. By combining behavior test and in vivo electrophysiological recording, we found that social observation can facilitate the observer's spatial representation of an unexplored environment...

This study investigated the risk of non-melanoma skin cancer (NMSC) in pre-dialysis patients with chronic kidney disease (CKD) and explored associated risk factors. A population-based cohort of 1,515,858 Taiwanese CKD patients was included. The standardized incidence ratio (SIR) for incident NMSC was determined. Compared with the general population, a 1.14-fold risk of NMSC was found in the CKD cohort. NMSC risk was significant in patients with pre-dialysis stage 5 CKD and anaemia (1.48-fold), and in those with uraemic pruritus after long-term antihistamine treatment (1...

Mesenchymal stem cells (MSCs) are well recognized for their ability to differentiate into type II alveolar epithelial (ATII) cells in damaged lungs, which is critical for reepithelization and recovery in acute lung injury (ALI). However, the high level of transforming growth factor-β (TGF-β) commonly seen in injured lung tissues is also able to induce MSCs to differentiate into fibroblast-like cells. In this study, we found that hypoxia could promote umbilical cord mesenchymal stem cells (UCMSCs) differentiation into ATII cells rather than into fibroblast-like cells, and this effect was mainly mediated by microRNA-145 (miR-145), which could induce the inhibition of TGF-β signaling by targeting TGF-β receptor II (TGFβRII)...

BACKGROUND: Despite the adverse effects of N-methyl-D-aspartate receptor (NMDAR) activity in cardiomyocytes, no study has yet examined the effects of NMDAR activity under ex vivo ischemic-reperfusion (I/R) conditions. Therefore, our aim was to comprehensively evaluate the effects of NMDAR activity through an ex vivo myocardial I/R rat model. METHODS: Isolated rat hearts were randomly segregated into six groups (n=20 in each group): (i) an untreated control group; (ii) a NMDA-treated control group; (iii) an untreated I/R group; (iv) an I/R+NMDA group treated with NMDA; (v) an I/R+NMDA+MK-801 group treated with NMDA and the NMDAR inhibitor MK-801; and (vi) an I/R+NMDA+[Ca]-free group treated with NMDA and [Ca]-free buffer...

One of the long-standing and challenging problems in microwave engineering is the realization of ultra-wideband absorption using extremely-thin structures. Magnetic material can facilitate thickness reduction for microwave absorbers but also bring inherent narrowband admittance matching conundrum originating from its frequency-dispersive permeability and high permittivity. In this paper, we propose a simple and yet effective solution based on the concept of admittance matching with non-Foster metasurface (NFMS)...

Central neurologic injury (CNI) causes dysfunctions not only in limbs but also in cognitive ability. We applied a novel peripheral nerve rewiring (PNR) surgical procedure to restore limb function. Here, we conducted a prospective study to develop estimates for the extent of preattentive processes to cognitive function changes in CNI patients after PNR. Auditory mismatch negativity (MMN) was measured in CNI patients who received the PNR surgery plus conventional rehabilitation treatment. During the 2-year follow-up, the MMN was enhanced with increased amplitude in the PNR plus rehabilitation group compared to the rehabilitation-only group as the experiment progressed, and progressive improvement in behavioural examination tests was also observed...

Mental disorders are severe, disabling conditions with unknown etiology and are commonly misdiagnosed when clinical symptomology criteria are solely used. Our previous work indicated that combination of serum levels of multiple proteins in tissue plasminogen activator (tPA)-brain-derived neurotrophic factor (BDNF) pathway improved accuracy of diagnosis of major depressive disorder (MDD). Here, we measured serum levels of tPA, plasminogen activator inhibitor-1 (PAI-1), BDNF, precursor-BDNF (proBDNF), tropomyosin-related kinase B (TrkB) and neurotrophin receptor p75 (p75NTR) in patients with paranoid schizophrenia (SZ, n = 34), MDD (n = 30), bipolar mania (BM, n = 30), bipolar depression (BD, n = 22), panic disorder (PD, n = 30), and healthy controls (HCs, n = 30) by Enzyme-linked immunosorbent assay kits...

NMDA-type glutamate receptors are ligand-gated ion channels that contribute to excitatory neurotransmission in the central nervous system (CNS). Most NMDA receptors comprise two glycine-binding GluN1 and two glutamate-binding GluN2 subunits (GluN2A-D). We describe highly potent (S)-5-[(R)-2-amino-2-carboxyethyl]-4,5-dihydro-1H-pyrazole-3-carboxylic acid (ACEPC) competitive GluN2 antagonists, of which ST3 has a binding affinity of 52 nM at GluN1/2A and 782 nM at GluN1/2B receptors. This 15-fold preference of ST3 for GluN1/2A over GluN1/2B is improved compared with NVP-AAM077, a widely used GluN2A-selective antagonist, which we show has 11-fold preference for GluN1/2A over GluN1/2B...

Nephrotoxicity remains a serious adverse effect of cisplatin chemotherapy, limiting its clinical usage. Numerous studies show that oxidative stress and inflammation are closely associated with cisplatin-induced renal damage. Astragaloside IV (AS-IV) has been found to possess antioxidant and anti-inflammation functions. Therefore, we investigated the potential curative effects of AS-IV against cisplatin-induced renal injury and the possible cellular mechanism for activity, both in vitro and in vivo. We found that pretreatment of HK-2 cells with AS-IV could mitigate cisplatin-induced cell damage caused by oxygen free radicals and the inflammatory response, as evidenced by reduced formation of reactive oxygen species (ROS) and inflammatory cytokines...

Closed head injury (CHI) usually results in severe and permanent neurological impairments, which are caused by several intertwined phenomena, such as cerebral edema, blood-brain barrier (BBB) disruption, neuronal loss, astroglial scarring and inflammation. We previously reported that induced neural stem cells (iNSCs), similar to neural stem cells (NSCs), can accelerate neurological recovery in vivo and produce neurotrophic factors in vitro. However, the effects of iNSC neurotrophy following CHI were not determined...

Genome-wide association studies have led to the discovery of several susceptibility genes related to autoimmune thyroid diseases (AITDs). However, controversial results have been reported regarding the role of single-nucleotide polymorphism (SNP) of CD40 in the disease susceptibility. The objective of this study was to identify the relationship of the polymorphisms of three sites of CD40 with the susceptibility to AITD in the Chinese population. We genotyped three polymorphisms of CD40: C/T -1 SNP, 58038T site of the third exon and C64610G site of the ninth exon in 196 GD cases, 121 HT cases and 122 control subjects...
