Prognostic significance of the 8th edition of the TNM classification for patients with extensive disease small cell lung cancer.

Background: Small cell lung cancer (SCLC) is typically categorized according to disease extent as limited or extensive, and utility of the 8th TNM classification, recommended for lung cancer staging, which demonstrates a strong association with non-small-cell lung cancer (NSCLC) management, remains unclear.

Methods: This retrospective study included 277 consecutive SCLC patients treated at a single institution between 2008 and 2016.

Results: According to the currently used two-stage system, 186 (65.

Amrubicin monotherapy for elderly patients with relapsed extensive-disease small-cell lung cancer: A retrospective study.

Background: Previous studies have shown amrubicin (AMR) to be an effective second-line treatment option for small-cell lung cancer (SCLC). However, the efficacy of AMR in elderly patients with relapsed SCLC has not been sufficiently evaluated.

Methods: The medical records of elderly patients with relapsed SCLC who received AMR as second-line chemotherapy were retrospectively reviewed, and their treatment outcomes were evaluated.

Intracranial Response to Nivolumab in a Patient with PD-L1-negative Lung Adenocarcinoma.

We herein report the case of a 52-year-old man with stage IV lung adenocarcinoma. The patient was negative for epidermal growth factor receptor (EGFR) mutations and echinoderm microtubule-associated protein-like 4 (EML4) /anaplastic lymphoma kinase (ALK) rearrangement. He was treated with nivolumab as a third-line chemotherapy.

Comparison of carboplatin plus etoposide with amrubicin monotherapy for extensive-disease small cell lung cancer in the elderly and patients with poor performance status.

Background: Carboplatin plus etoposide (CE) is a standard treatment for elderly patients with extensive-disease small cell lung cancer (ED-SCLC). However, amrubicin monotherapy (AMR) may be a feasible alternative. We compared the efficacies and safety profiles of CE and AMR for ED-SCLC in elderly patients and chemotherapy-naive patients with poor performance status (PS).

Activity of Nivolumab and Utility of Neutrophil-to-Lymphocyte Ratio as a Predictive Biomarker for Advanced Non-Small-Cell Lung Cancer: A Prospective Observational Study.

Background: The immune checkpoint inhibitor nivolumab is entering routine oncologic practice. We investigated the safety and efficacy of nivolumab in the real world and alternative predictive factors for survival in patients with advanced non-small-cell lung cancer (NSCLC).

Patients And Methods: We performed a prospective observational study to evaluate the activity of nivolumab treatment for chemotherapy-refractory NSCLC.

Smoking History as a Predictor of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors in Patients with Non-Small Cell Lung Cancer Harboring EGFR Mutations.

Background: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKIs) therapy has been recognized as the standard treatment for patients with non-small cell lung cancer (NSCLC) harboring EGFR mutations. However, resistance to EGFR-TKIs has been observed in certain subpopulations of these patients. We aimed to evaluate the impact of smoking history on the efficacy of EGFR-TKIs.

Efficacy of Platinum-Based Chemotherapy for Relapsed Small-Cell Lung Cancer after Amrubicin Monotherapy in Elderly Patients and Patients with Poor Performance Status.

Background: Previous studies have shown amrubicin to be an effective first- or second-line treatment option for small-cell lung cancer (SCLC). However, there have been few studies reporting the efficacy of platinum-based chemotherapy after amrubicin therapy. We aimed to evaluate the efficacy of platinum-based chemotherapy as second-line treatment for elderly patients and those with SCLC with poor performance status (PS) previously treated with amrubicin monotherapy.

Phase I study of Nedaplatin, a platinum based antineoplastic drug, combined with nab-paclitaxel in patients with advanced squamous non-small cell lung cancer.

Background This study was designed to determine the recommended dose of a combination of nedaplatin (NED) and nab-paclitaxel (nab-PTX) in chemotherapy-naive patients with advanced squamous non-small-cell lung cancer (NSCLC). Methods Patients received escalating doses of NED on day 1 and nab-PTX on days 1, 8, and 15 every 4 weeks by an intravenous infusion for up to six cycles. Results A dose of 100 mg/m NED and 100 mg/m nab-PTX was determined to be the recommended dose for patients with advanced squamous NSCLC.

Effects of Inhalation Aromatherapy on Symptoms of Sleep Disturbance in the Elderly with Dementia.

This study investigated the effects of inhalation aromatherapy on sleep disturbance in elderly individuals with dementia. In 19 subjects, normal sleep was observed for a 20-day control period, inhalation aromatherapy was then applied for a 20-day intervention period, and the control and intervention periods were compared. During the intervention period, essential oils were placed nightly on towels around the subjects' pillows.

Risk factors for parastomal hernia after abdominoperineal resection for rectal cancer.

Introduction: This study was designed to identity risk factors for parastomal hernia occurring after abdominoperineal resection for rectal cancer.

Methods: The study group was comprised of 158 patients with rectal cancer who underwent abdominoperineal resection in our department from January 1990 through December 2014. Twelve variables were studied as risk factors for parastomal hernia.

Trajectory and terminal distribution of single centrifugal axons from olfactory cortical areas in the rat olfactory bulb.

The olfactory bulb receives a large number of centrifugal fibers whose functions remain unclear. To gain insight into the function of the bulbar centrifugal system, the morphology of individual centrifugal axons from olfactory cortical areas was examined in detail. An anterograde tracer, Phaseolus vulgaris leucoagglutinin, was injected into rat olfactory cortical areas, including the pars lateralis of the anterior olfactory nucleus (lAON) and the anterior part of the piriform cortex (aPC).

Centrifugal innervation of the mammalian olfactory bulb.

Although it has been known for decades that the mammalian olfactory bulb receives a substantial number of centrifugal inputs from other regions of the brain, relatively few data have been available on the function of the centrifugal olfactory system. Knowing the role of the centrifugal projection and how it works is of critical importance to fully understanding olfaction. The centrifugal fibers can be classified into two groups, a group that release neuromodulators, such as noradrenaline, serotonin, or acetylcholine, and a group originating in the olfactory cortex.

Postnatal development of dendritic spines on olfactory bulb granule cells in rats.

Postnatal morphological changes in granule cell dendritic spines and filopodia (collectively referred to as "spines/filopodia") were examined in the rat main olfactory bulb to characterize the development of the neural circuitry for olfaction. Granule cells were labeled with a membrane dye and confocal laser scanning microscope images of labeled spines/filopodia were acquired in the following three dendritic domains: apical dendrites in the external plexiform layer, those in the granule cell layer, and basal dendrites. In all three domains the proportion of typical spines slightly increased during development, with a concomitant decrease in the proportion of "stubby" spines lacking a neck; the proportion of filopodia remained unchanged, accounting for 20-40% of all protrusions.

Brain-derived neurotrophic factor induces rapid morphological changes in dendritic spines of olfactory bulb granule cells in cultured slices through the modulation of glutamatergic signaling.

While the acute physiological effects of brain-derived neurotrophic factor (BDNF) have been well demonstrated, little is known regarding possible morphological effects that occur within a short period of time. The acute effects of BDNF on dendritic spine morphology were examined in granule cells in cultured main olfactory bulb slices. Organotypic slices prepared from 7-day-old rats were cultured for 1 day, and BDNF was applied at varying time points prior to fixation.

Differentiation of mitral cell dendrites in the developing main olfactory bulbs of normal and naris-occluded rats.

The morphological differentiation of mitral cell dendrites during embryonic and early postnatal development was examined in the main olfactory bulb of rats to determine a possible role of afferent activity in the development of the dendrites. Mitral cells and olfactory nerve fibers were labeled with 1,1'-dioctadecyl-3,3,3', 3'-tetramethylindocarbocyanine perchlorate (DiI) and fluorescein-conjugated lectin (Ulex europeus agglutinin-I), respectively. Morphogenesis of mitral cell dendrites proceeded as previously described (Malun and Brunjes [1996] J.

GABAergic neuron-to-astrocyte signaling regulates dendritic branching in coculture.

Effects of neurotransmitters on dendritic morphology were analyzed in cocultures of neurons and astrocytes from the neonatal rat olfactory bulb by means of immunocytochemical staining and morphometry. About 70% of the neurons gamma-aminobutyric acid (GABA)-immunoreactive on day 7 of the coculture. Morphometric analysis of neurons having no contact with other neurons revealed that incubation of the coculture with either a sodium channel blocker, tetrodotoxin, or GABAA receptor antagonists such as bicuculline or picrotoxin resulted in a decreased number of dendritic branch points as compared to neurons in control cultures, while the same treatment did not affect radial dendritic outgrowth or the number of primary dendrites.

Expression of nm23 protein in pulmonary adenocarcinomas: inverse 1orrelation to tumor progression.

Immunohistochemical assessment was made of nm23 protein expression in pulmonary adenocarcinoma. Of the 147 adenocarcinomas 67% (99/147) were weakly and 33% (48/147) strongly positive for nm23 protein. nm23 protein expression in primary tumors was shown to correlate inversely with advancing pathologic stage and the degree of metastasis in regional lymph nodes (P < 0.

Neuronal regulation of astrocyte morphology in vitro is mediated by GABAergic signaling.

The addition of isolated neurons to monolayers of cultured astrocytes induced a morphological change in the astrocytes that came into contact with the added neuronal cell bodies or neurites. The change, which included an increase in the complexity of cell shape, took at least 3 days to become detectable and was enhanced in proportion to the number of attached neurons. Astrocytes that did not make contact with any neurons had a less complex contour, comparable to those in control cultures with no neurons added.

A novel human monoclonal antibody rapidly induces homotypic cell aggregation and promotes antibody-secreting activity by human B lymphoblastoid cell line IM-9.

A human monoclonal antibody (mAb), designated mNKES, was generated by fusing B cells isolated from an enlarged cervical lymph node of a patient with a carotid body tumor (CBT), with human myeloma cell line KR-12 (6TG). The reactivity of mNKES was tested by the indirect immunofluorescence method. The antigen defined by mNKES was expressed on Burkitt's lymphoma cell lines Raji, Daudi, and Ramos and on B lymphoblastoid cell line IM-9.

A novel monoclonal antibody mNI-58A against the alpha-chain of leukocyte function-associated antigen-1 (LFA-1) blocks the homotypic cell aggregation and actively regulates morphological changes in the phorbol myristate acetate (PMA)-activated human monocyte-like cell line, U937.

A monoclonal antibody (mAb), designated mNI-58A, was produced by immunizing mice with the lipopolysaccharide (LPS)-stimulated monocyte-like cell line, U937. The antigen defined by mNI-58A was widely expressed on various lymphoid cells and all cell lines examined except the erythroid cell line, K562. When the reactive patterns between mNI-58A and the mAbs to various human differentiation antigens (CD11a, CD11b, CD11c, CD14, CD16, CD18, CD23, CD28, CD29, CD31, CD43, CD44, CD45RA, CD50, CD54, CD58, CD80, CD102, CD106, HLA-class I and-class II antigen) were compared, that of mNI-58A was found to be similar to those of the leukocyte function-associated antigen-1 (LFA-1) mAbs.

Development and characterization of a novel monoclonal antibody (mNI-11) that induces cell adhesion of the LPS-stimulated human monocyte-like cell line U937.

A monoclonal immunoglobulin G1 (IgG1) antibody (mAb), designated mNI-11, was produced by immunizing mice with the lipopolysaccharide (LPS)-stimulated monocyte-like cell line U937. The reactivity of mNI-11 was tested by the indirect immunofluorescence method. The antigen defined by mNI-11 was found to be expressed on U937 cells, LPS-stimulated U937 cells, normal CD14+ cells (monocytes/macrophages), and human umbilical vein endothelial cells (HUVECs).

[Monoclonal antibody mNI-58 inducing morphological changes in a human monocyte-like cell line, U937, stimulated with phorbol myristate acetate (PMA)].

A mouse monoclonal antibody (mAb), designated mNI-58, was produced. The mNI-58 markedly induced spread formation of the phorbol myristate acetate (PMA)-stimulated U937 cells (referred to as PMA-U937 cells) but not that of the resting U937 cells. This spread formation was completely blocked in the presence of cytochalasin D or cycloheximide.
