Non-functioning pituitary adenomas (NFPAs) are the most common pituitary tumors and mainly invade the sphenoid, cavernous sinus or dura mate. Aberrant regulation of the Wnt signaling pathway plays an important role in tumorigenesis. This study was designed to investigate the relationships between secreted frizzled-related proteins (sFRPs), WIF1 genes and the invasion of NFPAs by tissue microassays (TMAs) of samples from 163 patients. Significantly weaker staining of WIF1 and sFRP4 were detected in the invasive group compared with the non-invasive group by TMAs (p = 0...

Mantle cell lymphoma is usually negative for CD10 which is useful in distinguishing MCL from other CD10 + B cell lymphomas. Here we assessed the clinicopathologic features of 30 cases of CD10+ MCL, the largest series to date in the English literature, and compared them with a group of 212 typical MCL cases (CD5+, CD10-negative, CD23-negative, cyclin D1+). The 30 patients with CD10+ MCL included 17 men and 13 women with a median age of 68 years. Compared with CD10-negative MCL, patients with CD10+ MCL showed a lower male predominance ( p = 0...

We describe the clinical, morphologic, immunophenotypic and molecular genetic features of 15 cases of acute myeloid leukemia (AML) with t(4;12)(q12;p13). There were 9 men and 6 women, with a median age of 50 years (range, 17-76). Most patients had hypercellular bone marrow with a median blast count of 58% and multilineage dysplasia. Flow cytometry analysis showed myeloid lineage with blasts positive for CD13, CD33, CD34, CD38, CD117 and HLA-DR. Interestingly, aberrant CD7 expression was detected in 12/14 cases, and myeloperoxidase was either negative (3/15) or positive in only a small subset of the blasts (12/15)...

In riparian zones along the Tarim River in northeastern China, the co-dominance by Populus euphratica and Tamarix ramosissima at the early succession stage shifts to P. euphratica dominance in the late stages. However, little is known about how this shift is mediated by the highly variable water conditions in riparian zones. Here we conducted a mesocosm experiment in which we measured the physiological and morphological traits of these two co-occuring species grown in mixtures under simulated favorable groundwater condition and no groundwater availability...

Lead (Pb) exposure has been shown to affect presynaptic neurotransmitter release in the animal and cell models. The mechanism by which Pb exposure impairs neurotransmitter release remains unknown. In this study, we aimed to investigate the effect of Pb exposure on synaptic vesicle protein 2C (SV2C) and its molecular mechanism. SV2C promoter region contains a neuron-restrictive silencer element (NRSE) binding motif. Neuron-restrictive silencer factor (NRSF) is a transcription repressor that regulates gene expression by binding to NRSE...

Lymphoepithelial carcinoma (LEC) is an uncommon malignant neoplasm. Due to the complicated anatomical structure of the human head, standard imaging modalities including ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) scan remain limited in detection of salivary tumors. We used three-dimensional computed tomography angiography (3D-CT angiography) for the assessment and pre-operative surgical planning of facial fractures of a case with LEC. The study results demonstrated that 3D-CT angiography provided an insightful approach to preoperative evaluation in the treatment of salivary tumors...

Rhamnus davurica Pall. (R. davurica) has been used as a traditional medicine for many years in China and abroad and shown a wide spectrum of biological activities. Previously, we reported the phytochemical fingerprinting profile of R. davurica, its distinct anti-proliferative activities against HT-29 and SGC-7901 cell lines, and the topoisomerase I (Top I) ligands based on bio-affinity ultrafiltration and HPLC-MS (UF-HPLC-MS). Nevertheless, among the 32 peaks detected in the fingerprinting profile, the common bioactive constituents responsible for the anti-inflammatory and anti-proliferative activities in the extracts remain elusive...

Hierarchically ZnIn2 S4 nanosheet-constructed microwire arrays (NCMAs) on a zinc substrate have been synthesized for the first time through a one-step solvothermal method without using any template or surfactant. The as-synthesized ZnIn2 S4 microwires are constructed by vertical nanosheets preferentially exposing (006) facets, which are about 1-5 μm in diameters and larger than 10 μm in average length. Experimental results demonstrate that the hierarchically ZnIn2 S4 NCMAs are converted from intermediate components of single crystalline indium nanowires, which are generated along the direction of (101) planes by a displacement reaction between Zn and In3+ during the initial synthesis process...

Chronic lead exposure causes peripheral sympathetic nerve stimulation, including increased blood pressure and heart rate. Purinergic receptors are involved in the sympathoexcitatory response induced by myocardial ischemia injury. However, whether P2X4 receptor participates in sympathoexcitatory response induced by chronic lead exposure and the possible mechanisms are still unknown. The aim of this study was to explore the change of the sympathoexcitatory response induced by chronic lead exposure via the P2X4 receptor in the stellate ganglion (SG)...

The Philadelphia chromosome resulting from t(9;22)(q34;q11.2) or its variants is a defining event in chronic myeloid leukemia. It is also observed in several types of de novo acute leukemia, commonly in B lymphoblastic leukemia, and rarely in acute myeloid leukemia, acute leukemia of ambiguous lineage, and T lymphoblastic leukemia. Acquisition of the Philadelphia chromosome during therapy of acute leukemia and myelodysplastic syndrome is rare. We reported 19 patients, including 11 men and 8 women with a median age of 53 years at initial diagnosis...

Lead (Pb) is an environmental neurotoxic metal. Chronic exposure to Pb causes deficits of learning and memory in children and spatial learning deficits in developing rats. In this study we investigated the effects of Pb exposure on the expression of HMGB1 and HO-1 in rats and PC12 cells. The animals were randomly divided to three groups: control group; low lead exposure group; high lead exposure group; PC12 cells were divided into 3 groups: 0 μM (control group), 1 μM and 100 μM Pb acetate. The results showed that Pb levels in blood and brain of Pb exposed groups were significantly higher than that of the control group (p < 0...

Verticillium wilt (VW), caused by soil-borne fungi of the genus Verticillium, is a serious disease affecting a wide range of plants and leading to a constant and major challenge to agriculture worldwide. Cotton (Gossypium hirsutum) is the world's most important natural textile fiber and oil crop. VW of cotton is a highly devastating vascular disease, however, few resistant germplasms have been reported in cotton. An increasing number of studies have shown that RNA interference (RNAi) based host-induced gene silencing (HIGS) is an effective strategy for improving plant resistance to pathogens by silencing genes essential for the pathogenicity of these pathogens...

Diabetic neuropathic pain (DNP) is one of the common complications of diabetes. Depression (DP) is also one of the common complications of diabetes. P2X7 receptors play an important role in the transmission of nociceptive signal and are associated with depressive illness. In the study, the hyperalgesia, allodynia and depressive behaviours of rats with comorbidity of DNP and DP were confirmed by the thermal withdrawal latency (TWL) test, mechanical withdrawal threshold (MWT) test, sucrose preference test (SPT), immobility time of forced swimming test (IMFST) and open-field test (OFT)...

8q24/MYC rearrangements resulting in MYC overexpression occur most frequently in lymphoid neoplasms. MYC rearrangements rarely have been described in blastic plasmacytoid dendritic cell neoplasm (BPDCN). Over an 8-year period in our hospital, 5 of 41 (12%) patients with BPDCN were shown 8q24/MYC rearrangements, including 2 with t(6;8)(p21;q24), 1 with t(8;14)(q24;q32), 1 with t(X;8)(q24;q24), and 1 with t(3;8)(p25;q24). 8q24/MYC rearrangement was present in the stemline in 4 patients and in the sideline in one; the latter was a patient with primary myelofibrosis who then developed BPDCN...

MXene is an emerging class of 2D materials exfoliated from ternary carbide and nitride ceramics. The exfoliation process, which is an acid etching approach, functionalizes the MXene surface with -OH, -O and -F groups. These functional groups offer significant opportunities for tuning the colloidal properties of the MXene nanoblocks; importantly, this tunability points the way towards a facile route for assembling these nanoblocks into 3D architectures that are in demand for many applications. This route, presented for the first time here, uses water/oil interfaces for assembling Ti3C2-MXene in 3D architectures...
