Plexin C1 is a transmembrane receptor and plexin C1 overexpression might have role in carcinogenesis. Hepatocellular carcinoma (HCC) has poor prognosis because of its aggressive behavior and limited treatment options, especially in advanced stage. We recently documented that Plexin C1 was overexpressed in HCC. We aimed to evaluate the prognostic significance of Plexin C1 overexpression in HCC in the present study.

Plexin C1 overexpression was evaluated immunohistochemically on paraffin-embedded blocks of the HCC patients. Plexin C1 immunohistochemical staining was scored. Plexin C1 overexpression staining intensity and prevalence were used for plexin scale staining evaluation and plexin scores were estimated according this staining scale. Plexin C1 score and its association with survival and clinicopathological features was assessed.

Sixty-seven HCC patients with adequate tissue for pathological evaluation were included. Median age was 63 years with male predominance (male to female ratio was 4.75 (n 57/12). Well-differentiated HCC (53.7%) patients had higher plexin C1 overexpression (p < 0.05). Median OS was 22.1 months. Patients with lower plexin C1 score (< 12) had shorter OS (17.5 vs 30.1 months, p = 0.036). Neutrophil count, GGT, and PNR (platelet/neutrophil ratio) had prognostic significance (p = 0.047, p = 0.018, and p = 0.045).

Plexin C1 overexpression is inversely correlated with grade in HCC. The patients with lower rate of Plexin C1 overexpression have worse survival outcome. It might be a prognostic factor in HCC.

However, proximity of the operator to the X-ray unit raises radiation safety concerns. The aim of this study was to evaluate operator radiation exposure and methods of dose reduction for the Rextar X camera-style hand-held dental X-ray unit. Leakage and scattered radiation were measured using a solid state detector. Scatter was generated using a Perspex head phantom. Measurements of scattered radiation dose as a function of distance were made with and without a lead acrylic scatter shield (0.6 mm Pb equivalence at 100 kVp) attached to the X-ray unit. Without the scatter shield, doses to the operator from a single adult maxillary molar X-ray exposure were 0.69, 0.78 and 0.47 µGy at the left hand, right hand and eyes respectively. With the scatter shield attached, doses were reduced to 0.25, 0.12 and 0.15 µGy respectively, corresponding to a dose reduction of 64, 85 and 68%. The contribution from leakage radiation was insignificant in comparison. It is highly unlikely that an operator would reach occupational dose limits when using the Rextar X hand-held dental X-ray unit, even without the scatter shield in place. Nevertheless, it is strongly recommended that the scatter shield is attached to keep operator doses as low as reasonably achievable. Use of the scatter shield additionally ensures compliance with the Australian legislative requirement for a protective barrier and is considered a preferable alternative to X-ray protective clothing.The embodied creative practice of dance facilitates a particular kind of awareness or attunement which can inform both the therapeutic and the intellectual work of the Health Humanities. This paper therefore considers dance as a way of 'doing' Health Humanities in two interlinked ways dance as a way of healing and dance as a way of knowing. SBI-0206965 supplier In bringing together carnal and the creative dimensions of human experience, dance offers us a way of making sense of our place in the world that provides us both with much needed existential security (tethering) and much needed epistemological freedom (untethering).Information concerning arbuscular mycorrhizal (AM) fungal geographical distribution in tropical and subtropical soils from the Atlantic Forest (a global hotspot of biodiversity) are scarce and often restricted to the evaluation of richness and abundance of AM fungal species at specific ecosystems or local landscapes. In this study, we hypothesized that AM fungal diversity and community composition in subtropical soils would display fundamental differences in their geographical patterns, shaped by spatial distance and land-use change, at local and regional scales. AM fungal community composition was examined by spore-based taxonomic analysis, using soil trap cultures. Acaulospora koskei and Glomus were found as generalists, regardless of mesoregions and land uses. Other Acaulospora species were also found generalists within mesoregions. Land-use change and intensification did not influence AM fungal composition, partially rejecting our first hypothesis. We then calculated the distance-decay of similarities amos.Dust is a major vehicle for the dispersal of microorganisms across the globe. While much attention has been focused on microbial dispersal in dust plumes from major natural dust sources, very little is known about the fractionation processes that select for the "dust microbiome." The recent identification of highly emissive, agricultural land dust sources in South Africa has provided the opportunity to study the displacement of microbial communities through dust generation and transport. In this study, we aimed to document the microbial communities that are carried in the dust from one of South Africa's most emissive locations, and to investigate the selective factors that control the partitioning of microbial communities from soil to dust. For this purpose, dust samples were generated at different emission sources using a Portable In-Situ Wind Erosion Lab (PI-SWERL), and the taxonomic composition of the resulting microbiomes was compared with the source soils. Dust emission processes resulted in the clear fractionation of the soil bacterial community, where dust samples were significantly enriched in spore-forming taxa. Conversely, little fractionation was observed in the soil fungal communities, such that the dust fungal fingerprint could be used to identify the source soil. Dust microbiomes were also found to vary according to the emission source, suggesting that land use significantly affected the structure and fractionation of microbial communities transported in dust plumes. In addition, several potential biological allergens of fungal origin were detected in the dust microbiomes, highlighting the potential detrimental effects of dust plumes emitted in South Africa. This study represents the first description of the fractionation of microbial taxa occurring at the source of dust plumes and provides a direct link between land use and its impact on the dust microbiome.

Immunotherapy for programmed cell death 1 (PD-1) and its ligand, PD-L1, has been considered an effective treatment for ovarian cancer.

F-labeled fluoro-2-deoxyglucose positron emission tomography/computed tomography (

F-FDG PET/CT) is a widely used noninvasive imaging tool for diagnosing several cancers. In this study, we investigated the association between PD-L1 expression and the maximum standardized uptake value (SUVmax) using

F-FDG PET/CT.

We retrospectively analyzed clinical data of patients with ovarian cancer who underwent

F-FDG PET/CT. Patients were categorized into two groups according to PD-L1 expression results. The relationship between clinicopathological characteristics of patients with ovarian cancer and PD-L1 expression was examined.

SUVmax was significantly higher in PD-L1-positive tumors than in PD-L1-negative tumors (16.1 ± 5.2 and 12.7 ± 7.0, respectively; p = 0.026). There were no significant differences in age, histologic type, and tumor grade between the PD-L1-negative and PD-L1-positive groups. The receiver operating characteristic curve analysis demonstrated that the highest accuracy (61.8%) for predicting PD-L1 expression was obtained with an SUVmax cutoff value of 10.5.

There was a significant correlation between

F-FDG uptake and PD-L1 expression, suggesting a role of

F-FDG PET/CT in selecting ovarian cancer candidates for anti-PD-L1 antibody therapy.

There was a significant correlation between 18F-FDG uptake and PD-L1 expression, suggesting a role of 18F-FDG PET/CT in selecting ovarian cancer candidates for anti-PD-L1 antibody therapy.Transient protein expression in a heterologous system has been very useful in many research fields. As a plant expression system, tobacco has some unique advantages including big leaves, simple infiltration and transformation, high activity in expressing transgenes, and easy sampling for microscopy. Because of these advantages, tobacco system has been extensively used for many purposes, such as large-scale expression and purification of proteins of interest, protein colocalization, protein degradation, protein-protein interaction assays including co-immunoprecipitation (CoIP), fluorescence resonance energy transfer (FRET), and bimolecular fluorescence complementation (BiFC), transcription regulation, plant-pathogen interactions, and functional verification of small RNAs. A large number of publications have used this system and generated critical results to support their conclusions. The results obtained from tobacco system are highly reproducible and mostly consistent with those generated from traditional techniques, indicating its reliability. Here we describe a protocol for studying protein-protein interactions in tobacco system, which could be applied to multiple experimental purposes as the procedure of tobacco leaf infiltration is basically shared among them.Cryptochromes are photolyase-like blue-light receptors found in all major evolutionary lineages (Ahmad and Cashmore, Nature 366162-166, 1993; Lin, Plant Physiol 1101047, 1996; Cashmore, Cell 114537-543, 2003; Partch and Sancar, Methods Enzymol 393726-745, 2005). Arabidopsis cryptochrome 1 (CRY1) and cryptochrome 2 (CRY2) mediate primarily blue-light inhibition of hypocotyl elongation and photoperiodic control of floral initiation (Ahmad and Cashmore, Nature 366162-166, 1993; Somers et al., Science, 2821488-1490, 1998; Guo et al., Science 279 (5355)1360-1363, 1998; Yu et al., Arabidopsis Book 8e0135, 2010). It has been proposed that phototransduction of cryptochromes involves the blue-light-dependent protein interactions, such as AtCRY2-CIB1 (CRYPTOCHROME-INTERACTING BASIC-HELIX-LOOP-HELIX 1), AtCRY1-PIF4 (PHYTOCHROME INTERACTING FACTOR 4) modules, sequentially mediate gene expression and plant growth (Liu et al., Science 322 (5907)1535-1539, 2008; Ma et al., Proc Natl Acad Sci U S A 113 (1)224-229, 2016; Wang et al., Science 354343-347, 2016). Cryptochromes also showed blue light response in vitro when expressed in Sf9 insect cells using the baculovirus expression system, thus the wavelength-specific CRY2-CIB1 interaction can also be observed in Semi-in-vivo pull-down assay (Li et al., Proc Natl Acad Sci U S A 108 (51)20844-20849, 2011; Liu et al., EMBO Reports, 2018). Here, we describe the detailed process of blue light-dependent CRY2-CIB1 interaction in Semi-in-vivo conditions.
