Rice blast disease caused by Magnaporthe oryzae is one of the most devastating fungal diseases of rice and results in a huge loss of rice productivity worldwide. During the infection process, M. oryzae secretes a large number of glycosyl hydrolase proteins into the host apoplast to digest the cell wall and facilitate fungal ingression into host tissues. In this study, we identified a novel arabinofuranosidase-B (MoAbfB) protein that is secreted by M. oryzae during fungal infection. Deletion of MoAbfB from M...

A significant number of children with T-lineage acute lymphoblastic leukemia (T-ALL) fail to respond to therapy and experience early relapse. CD99 has been shown to be overexpressed on T-ALL cells and is considered to be a reliable detector of the disease. However, the relevance of CD99 overexpression in ALL has not been investigated in a functional context. The aim of this study was to investigate the functional capacity of CD99+ cells in childhood ALL and determine the suitability of CD99 as a therapeutic target...

Saxitoxin (STX), a principal phycotoxin contributing to paralytic shellfish poisoning, is largely produced by marine microalgae of the genus Alexandrium. This toxin affects a wide range of species, inducing massive deaths in fish and other marine species. However, marine bivalves can resist and accumulate paralytic shellfish poisons. Despite numerous studies on the impact of STX in marine bivalves, knowledge regarding STX recognition at molecular level by benthic species remains scarce. Therefore, the aim of this study was to identify novel genes that interact with STX in the Chilean mussel Mytilus chilensis...

The on-going generation of HIV-1 inter-subtype recombination has led to new circulating recombinant forms (CRFs) and unique recombinant forms (URFs) in Asia. Here, we evaluated whether previously reported URFs were actually CRFs. All available complete or near full-length HIV-1 URFs sequences from Asia were retrieved from the HIV Los Alamos National Laboratory Sequence database, and phylogenetic, transmission cluster and bootscan analyses were performed using MEGA 6.0, Cluster Picker 1.2.1, and SimPlot3.5.1...

Immunotherapy is the revolution in cancer treatment of this last decade. Among multiple approaches able to harness the power of the immune system against cancer, T cell based immunotherapies represent one of the most successful examples. In particular, biotechnological engineering of protein structures, like the T cell receptor or the immunoglobulins, allowed the generation of synthetic peptides like chimeric antigen receptors and bispecific antibodies that are able to redirect non-tumor specific T cells to recognize and kill leukemic cells...

Leukemia cutis develops in <4% of all acute leukemias. Concurrent acute myeloid leukemia (AML) and Langerhans cell histiocytosis (LCH) is rare, with most cases involving lymph nodes or spleen, and no cutaneous involvement. We report the case of a 59-year-old man who presented with fever, malaise, and fatigue. The CBC showed leukocytosis (30.4 × 10/L, 9% blasts), anemia, and thrombocytopenia. Bone marrow biopsy was diagnosed with AML, not otherwise specified, with mutations of FLT3 and IDH2 (R140Q). The patient developed skin rash on the right flank with the clinical differential diagnosis of herpes simplex virus or varicella-zoster virus infection/reactivation versus leukemia cutis...

BACKGROUND: Nitric oxide (NO) functions as a critical signaling molecule in the low-temperature stress responses in plants, including polarized pollen tube growth in Camellia sinensis. Despite this, the potential mechanisms underlying the participation of NO in pollen tube responses to low temperature remain unclear. Here, we investigate alterations to gene expression in C. sinensis pollen tubes exposed to low-temperature stress and NO using RNA-Seq technology, in order to find the potential candidate genes related to the regulation of pollen tube elongation by NO under low-temperature stress...

In clinical applications, osseointegration is essential for the long-term stability of dental implants. Inspired by the hierarchical structure of natural bone, we applied the electrochemical etching (EC) technique to form a micro-nano structure on a titanium alloy (Ti6Al4V) substrate, called EC surface. Sand blasting and acid etching (SLA) and machined (M) methods were employed to generate micro and smooth textures, respectively, as the control groups. The surface topographies of the three substrates were characterized using scanning electron microscopy (SEM)...

Spine injuries are more prevalent among Iraq and Afghanistan veterans than among veterans of previous conflicts. The purpose of this investigation was to characterize the context, mode, and clinical outcomes of spine injuries sustained by U.S. military personnel in theater. Injury and clinical data from patients who sustained a spine injury in Iraq or Afghanistan between 2003 and 2008 were extracted from the Joint Theater Trauma Registry. Fischer's exact test was used to compare demographic variables between battle and nonbattle spine injuries...

The application of lessons learned on the battlefield for timely surgical control of lower extremity hemorrhage secondary to blast injuries to the civilian practice for similar wounding patterns from industrial accidents or terrorist activities is imperative. Although simple cut-down procedures are commonly sufficient for the control of blood vessels for distal extremity traumatic amputations, high-thigh or disarticulation wounding patterns often require more complex surgical methods. The following details both the decision-making process and operative techniques for controlling hemorrhage from lower extremity blast injuries...

A 76-years old man presented with leucocytosis (86x109/l), fever, pneumonia and significant weight loss. He had a history of chronic lymphocytic leukemia diagnosed five years earlier and he responded with partial remission to the treatment with continuous low doses of chlorambucil. Analysis of blood smear, bone marrow aspiration and bone marrow biopsy revealed predomination of small lymphocytes, but 22% of cells were blasts negative to cytochemical stainings (Figure 1). Flow cytometric analysis showed two distinct populations: 65% of cells was small to moderate in size, CD19+, CD45+, CD5+, CD20+/-, but 30% of cells were large, CD34+, CD13+, HLA DR+, CD65+, CD45+, MPO weakly positive and CD33, CD14, CD15, CD16 negative...

In military populations, traumatic brain injury (TBI) also holds potential to increase impulsivity and impair mood regulation due to blast injury effects on ventral frontal cortex - to put military personnel at risk for suicide or substance abuse. We assessed a linkage between depression and impaired behavioral inhibition in 117 blast-exposed service members (SM) and veterans with post-concussion syndrome (PCS), where PCS was defined using a Rivermead Postconcussive Symptom Questionnaire (RPQ) modified to clarify whether each symptom worsened compared to pre-blast...

Kringle 5, the fifth fragment of plasminogen, is known to be important for inhibiting the proliferation and migration of vascular endothelial cell (VEC), while not having any effects on normal endothelial cells. Therefore, it may be a potential tumor therapy candidate. However, the ligand of the Kringle 5 in VEC has not yet been identified. In this study, the possible ligand of Kringle 5 in vitro was screened and validated using Ph.D.-7 phage display peptide library with molecular docking, along with surface plasma resonance (SPR)...
