INTRODUCTION Immune checkpoint inhibition has shifted treatment paradigms in non-small cell lung cancer (NSCLC). Conflicting results have been reported regarding the immune infiltrate and programmed death-ligand 1 (PD-L1) as a prognostic marker. We correlated the immune infiltrate and PD-L1 expression with clinicopathologic characteristics in a cohort of resected NSCLC. METHODS A tissue micro...

A group of 76 polycythemia vera patients was followed prospectively with bone marrow examinations at regular intervals. Six terminated in acute leukemia, preceded by an indolent preleukemic phase succeeded by a very fulminant leukemia. At autopsy, all patients had extramedullary hematopoiesis. In one of them, only the bone marrow was leukemic, suggesting that it was the primary site of this tra...

A FITC-induced allergic contact hypersensitivity model was used to investigate the role that the prostaglandin D(2) receptor-chemoattractant receptor-homologous molecule expressed on T(h)2 cells (CRTH2) plays in modulating cutaneous inflammation. Our results show that inhibition of CRTH2, achieved via administration of a potent, small molecule antagonist, Compound A (Cmpd A), effectively blocke...

The endometrial stromal nodule is a benign tumor composed of differentiated endometrial stromal cells arranged as a well circumscribed nodule with smooth non-invasive margins. They are rare neoplasms, diagnosed in most instances by microscopy. Although nodules are benign in nature, hysterectomy is the treatment of choice to enable evaluation of the tumor margins which are well demarcated in...

Chloroplasts, or photosynthetic plastids, multiply by binary fission, forming a homogeneous population in plant cells. In Arabidopsis thaliana, the division apparatus (or division ring) of mesophyll chloroplasts includes an inner envelope transmembrane protein ARC6, a cytoplasmic dynamin-related protein ARC5 (DRP5B), and members of the FtsZ1 and FtsZ2 families of proteins, which co-assemble in ...

The complex interplay of the tumour microenvironment (TME) and its role in disease progression and response to therapy is poorly understood. The majority of studies to date focus on individual components or molecules within the TME and so lack the power correlative analysis. Here we have performed a multi-parameter analysis of the TME in 62 resectable non-small cell lung cancer (NSCLC) specimen...

We have made a detailed inventory of the immune infiltrate of gastrointestinal stromal tumors (GISTs), which originate from mesenchymal cells in the intestinal tract. These sarcomas are heavily infiltrated with macrophages and T cells, while immune cells of other lineages were much less abundant. Dissecting the functional subtypes of T cells with multicolor fluorescent microscopy revealed subst...

background: tumor associated tissue eosinophilia is believed to play a significant role in the biological behavior of the carcinoma. eosinophil infiltrate in association with the head and neck squamous cell carcinoma (scc) have been reviewed from time-to-time. the significance of such an association has been variably thought to be either a potential diagnostic tool for stromal invasion or as a ...

Self-diffusivity of a large tracer ring polymer, Dr, immersed in a matrix of linear polymers with Nl monomers each shows unusual length dependence. Dr initially increases, and then decreases with increasing Nl. To understand the relationship between the nonmonotonic variation in Dr and threading by matrix chains, we perform equilibrium Monte Carlo simulations of ring-linear blends in which the ...

A 29-year-old male presented with an annular plaque on his arm for 7 months. Physical examination revealed 6 mm annular plaque with raised borders and a shiny stellatepurple center (Fig. 1). Dermoscopic evaluation revealed a ring of white spiked structurless areas at the periphery; an intense structurless steel purple area was observed at the center of the lesion (Fig. 2). Hystopathological exa...
