Image Feature Detectors in Agricultural Harvesting: An Evaluation.

Image feature detection serves as the cornerstone for numerous vision applications, and it has found extensive use in agricultural harvesting. Nevertheless, determining the optimal feature extraction technique for a specific situation proves challenging, as the Ground Truth correlation between images is exceedingly elusive in harsh agricultural harvesting environments. In this study, we assemble and make publicly available the inaugural agricultural harvesting dataset, encompassing four crops: rice, corn and soybean, wheat, and rape.

Effects of different electrostatic field intensities assisted controlled freezing point storage on water holding capacity of fresh meat during the early postmortem period.

In this study, the effect of different intensity electrostatic fields on the water holding capacity (WHC) of fresh meat during the early postmortem period in controlled freezing point storage (CFPS) were investigated. Significantly lower cooking loss were found in low voltage electrostatic field (LVEF) and high voltage electrostatic field (HVEF) compared to the control group (CK) (p < 0.05).

Development of Plastic/Gelatin Bilayer Active Packaging Film with Antibacterial and Water-Absorbing Functions for Lamb Preservation.

In order to extend the shelf life of refrigerating raw lamb by inhibiting the growth of microorganisms, preventing the oxidation of fat and protein, and absorbing the juice outflow of lamb during storage, an active packaging system based on plastic/gelatin bilayer film with essential oil was developed in this study. Three kinds of petroleum-derived plastic films, oriented polypropylene (OPP), polyethylene terephthalate, and polyethylene, were coated with gelatin to make bilayer films for lamb preservation. The results showed significant improvement in the mechanical properties, oxygen, moisture, and light barriers of the bilayer films compared to the gelatin film.

Vertex points are not enough: Monocular 3D object detection via intra- and inter-plane constraints.

Existed methods for 3D object detection in monocular images focus mainly on the class of rigid bodies like cars, while more challenging detection like the cyclist is less studied. Therefore, we propose a novel 3D monocular object detection method to improve the accuracy of detection objects with large differences in deformation by introducing the geometric constraints of the object 3D bounding box plane. Considering the map relationship of projection plane and the keypoint, we firstly introduce the geometric constraints of the object 3D bounding box plane, adding the intra-plane constraint while regressing the position and offset of the keypoint itself, so that the position and offset error of the keypoint are always within the error range of the projection plane.

A Phase II Study Evaluating the Safety and Efficacy of Sunitinib Malate in Combination With Weekly Paclitaxel Followed by Doxorubicin and Daily Oral Cyclophosphamide Plus G-CSF as Neoadjuvant Chemotherapy for Locally Advanced or Inflammatory Breast Cancer.

Introduction: Neoadjuvant chemotherapy is standard treatment for locally advanced breast cancer (LABC) or inflammatory breast cancer (IBC). We hypothesized that adding sunitinib, a tyrosine kinase inhibitor with antitumor and antiangiogenic activity, to an anthracycline and taxane regimen would improve pathologic complete response (pCR) rates to a prespecified endpoint of 45% in patients with HER2-negative LABC or IBC.

Methods: We conducted a multicenter, phase II trial of neoadjuvant sunitinib with paclitaxel (S+T) followed by doxorubicin and cyclophosphamide plus G-CSF for patients with HER2-negative LABC or IBC.

Hypoxic mast cells accelerate the proliferation, collagen accumulation and phenotypic alteration of human lung fibroblasts.

Pulmonary vascular remodeling and fibrosis are the critical pathological characteristics of hypoxic pulmonary hypertension. Our previous study demonstrated that hypoxia is involved in the functional alteration of lung fibroblasts, but the underlying mechanism has yet to be fully elucidated. The aim of the present study was to investigate the effect of mast cells on the proliferation, function and phenotype of fibroblasts under hypoxic conditions.

Interferon regulatory factor 3 mediates Poly(I:C)-induced innate immune response and apoptosis in non‑small cell lung cancer.

Immunotherapy is considered one of the most promising treatments for lung cancer. The cell signalling molecules melanoma differentiation-associated protein 5 (MDA5) and retinoic acid-inducible gene I protein (RIG‑I) are essential receptors that recognise intracellular pathogen-associated nucleic acids, whereas interferon regulatory factor 3 (IRF3) controls the expression of innate immunity-associated genes in macrophages. However, the innate immune response to polyinosinic:polycytidylic acid [Poly(I:C)] in lung cancer remains to be elucidated.

Hypoxia induces pulmonary arterial fibroblast proliferation, migration, differentiation and vascular remodeling via the PI3K/Akt/p70S6K signaling pathway.

The present study was designed to examine whether hypoxia induces the proliferation, migration and differentiation of pulmonary arterial fibroblasts (PAFs) via the PI3K/Akt/p70S6K signaling pathway. PAFs were subjected to normoxia (21% O2) or hypoxia (1% O2). The proliferation, migration, differentiation and cellular p110α, p‑Akt, and p‑p70S6K expression levels of the PAFs were examined in vitro.

Late acute graft-versus-host disease: a prospective analysis of clinical outcomes and circulating angiogenic factors.

Late acute (LA) graft-versus-host disease (GVHD) is persistent, recurrent, or new-onset acute GVHD symptoms occurring >100 days after allogeneic hematopoietic cell transplantation (HCT). The aim of this analysis is to describe the onset, course, morbidity, and mortality of and examine angiogenic factors associated with LA GVHD. A prospective cohort of patients (n = 909) was enrolled as part of an observational study within the Chronic GVHD Consortium.

Late Acute and Chronic Graft-versus-Host Disease after Allogeneic Hematopoietic Cell Transplantation.

Several distinct graft-versus-host disease (GVHD)-related syndromes have been defined by the National Institutes of Health Consensus Conference. We enrolled a prospective cohort of 911 hematopoietic cell transplantation (HCT) recipients at 13 centers between March 2011 and May 2014 to evaluate 4 GVHD syndromes: late acute GVHD (aGVHD), chronic GVHD (cGVHD), bronchiolitis obliterans syndrome, and cutaneous sclerosis. The median age at HCT was 53.

Predictors of survival, nonrelapse mortality, and failure-free survival in patients treated for chronic graft-versus-host disease.

Chronic graft-versus-host disease (GVHD) is a pleotropic syndrome that lacks validated methods of measuring response in clinical trials, although several end points have been proposed. To investigate the prognostic significance of these proposed end points, such as the 2005 National Institutes of Health (NIH) response measures, 2014 NIH response measures, clinician-reported response, and patient-reported response, we tested their ability to predict subsequent overall survival (OS), nonrelapse mortality (NRM), and failure-free survival (FFS). Patients (n = 575) were enrolled on a prospective chronic GVHD observational trial.

Fluticasone, Azithromycin, and Montelukast Treatment for New-Onset Bronchiolitis Obliterans Syndrome after Hematopoietic Cell Transplantation.

Bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic cell transplantation (HCT) is associated with high mortality. We hypothesized that inhaled fluticasone, azithromycin, and montelukast (FAM) with a brief steroid pulse could avert progression of new-onset BOS. We tested this in a phase II, single-arm, open-label, multicenter study (NCT01307462).

A Randomized Phase II Crossover Study of Imatinib or Rituximab for Cutaneous Sclerosis after Hematopoietic Cell Transplantation.

Purpose: Cutaneous sclerosis occurs in 20% of patients with chronic graft-versus-host disease (GVHD) and can compromise mobility and quality of life.

Experimental Design: We conducted a prospective, multicenter, randomized, two-arm phase II crossover trial of imatinib (200 mg daily) or rituximab (375 mg/m(2) i.v.

Candidate early detection protein biomarkers for ER+/PR+ invasive ductal breast carcinoma identified using pre-clinical plasma from the WHI observational study.

Estrogen receptor (ER)-positive/progesterone receptor (PR)-positive invasive ductal carcinoma accounts for ~45 % of invasive breast cancer (BC) diagnoses in the U.S. Despite reductions in BC mortality attributable to mammography screening and adjuvant hormonal therapy, an important challenge remains the development of clinically useful blood-based biomarkers for risk assessment and early detection.

Assessing the relationship between oral chronic graft-versus-host disease and global measures of quality of life.

Objective: Chronic GVHD (cGVHD) is a frequent complication of allogeneic hematopoietic stem cell transplantation (HSCT) and affects multiple organ systems, with the oral cavity being one of the most frequently affected sites. Patients with cGVHD experience reduced quality of life (QOL), yet the specific impact of oral cGVHD on QOL is poorly understood. The objective of this study was to characterize the impact of oral cGVHD on global measures of QOL.
