Anthropometric test devices (ATDs) such as Hybrid III dummy have been widely used in automotive crash tests to evaluate the risks of injury at different body regions. In recent years, researchers have started using automotive ATDs to study the high-speed vertical loading response caused by underbelly blast (UBB) impacts. This study analyzed the Hybrid III dummy responses to short-duration large magnitude vertical acceleration in a laboratory setup. Two unique test conditions were investigated using a horizontal sled system to simulate the UBB loading conditions...

Leukemia is broadly divided into acute and chronic lymphocytic and myeloid types based on the proportion of blasts, morphology of cells, and expression of specific antigens on neoplastic cells. Classifying leukemia in horses can be challenging if blasts predominate and since few antibodies to identify cell types are available. The objective of this study was to describe in detail the clinical and pathologic features of acute leukemia in horses. Twelve horses ranging from 0.2 to 25.9 years of age were diagnosed with acute leukemia...

OBJECTIVES: The effects of blast exposure have gained increasing interest in the military medical community with their continued occurrence on the battlefield. The impact of the direct and indirect energy imparted from blasts to hollow viscera, as well as closed head injuries, have been well studied. However, the injury to articular cartilage has not been investigated, despite previous correlations regarding the development of osteoarthritis. The purpose of this study was to assess the degree of injury to articular chondrocytes after exposure to a simulated blast overpressure wave...

Recent reports state that C-type lectin-like molecule-1 (CLL-1) in acute myeloid leukemia (AML) is expressed primarily on myeloid cells, but there is still no investigation about its prognostic significance on leukemic blast compartment. Hence, this study aimed to evaluate the prognostic value of CLL-1 in 123 patients with de novo CD34+ non-M3 AML. Multiparameter flow cytometry was used to assess the expression of CLL-1 on immature compartment in AML and control groups. We found that CLL-1 expression level on blast compartment was closely linked to clinical characteristics, treatment response and survival outcome of patients...

BACKGROUND AND AIMS: The administration of ex-vivo expanded Natural killer (NK) cells as potential antitumor effector cells appears to be suitable for effector cell-based immunotherapies in high-risk cancer patients. However, the GMP-conform manufacturing of clinical-grade NK cells at sufficiently high numbers represent a great challenge. Therefore, we improved and optimized previous expansion protocols for those effector cells through the use of newly developed culture medium, IL-21 and autologous feeder cells...

Ventilator-associated pneumonia (VAP) is a common nosocomial infection in neonatal intensive care units with high morbidity and mortality. Bacterial biofilm in the endotracheal tube (ET) provides a notable and persistent source of pathogens that may cause VAP, and thus is important for VAP detection. However, during intubation microbial investigations in ET, samples are unavailable due to the infeasibility of collecting ET samples during intubation of neonates. It is therefore of great importance to find alternative sources of samples that can help identify the ET biofilm flora...

T regulatory cells (Tregs) play a key role in modulating T cell responses. Clinical trials showed that Tregs modulate graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, their ability to mediate anti-leukemic activity (graft-versus-leukemia [GvL]) is largely unknown. Enforced interleukin-10 (IL-10) expression converts human CD4(+) T cells into T regulatory type 1 (Tr1)-like (CD4(IL-10)) cells that suppress effector T cells in vitro and xenoGvHD in humanized mouse models...

Most of Chinese medicinal herbs are subjected to traditional processing procedures, including stir-frying, charring, steaming, boiling, and calcining before they are released into dispensaries. The marketing and identification of processed medicinal materials is a growing issue in the marketplace. However, conventional methods of identification have limitations, while DNA mini-barcoding, based on the sequencing of a short-standardized region, has received considerable attention as a new potential means to identify processed medicinal materials...

BACKGROUND: The electric organ of Tetronarce californica (an electric ray formerly known as Torpedo californica) is a classic preparation for biochemical studies of cholinergic neurotransmission. To broaden the usefulness of this preparation, we have performed a transcriptome assembly of the presynaptic component of the electric organ (the electric lobe). We combined our assembled transcriptome with a previous transcriptome of the postsynaptic electric organ, to define a MetaProteome containing pre- and post-synaptic components of the electric organ...

In the rice blast fungus Magnaporthe oryzae, the cAMP-PKA pathway regulates surface recognition, appressorium turgor generation, and invasive growth. However, deletion of CPKA failed to block appressorium formation and responses to exogenous cAMP. In this study, we generated and characterized the cpk2 and cpkA cpk2 mutants and spontaneous suppressors of cpkA cpk2 in M. oryzae. Our results demonstrate that CPKA and CPK2 have specific and overlapping functions, and PKA activity is essential for appressorium formation and plant infection...

BACKGROUND: It is well established that expression of multi-drug resistance (MDR) proteins (MDR1, BCRP, MDR3, MRP1 and LRP) in leukemic blasts correlates with AML patients clinical response. Assuming that leukemic stem cells (LSC) are resistant to chemotherapy and responsible for relapse it might be clinically relevant to evaluate the expression level of MDR proteins in LSC and relate it to the clinical outcome. METHODS: Bone marrow samples from 26 patients with de novo AML were labeled with antibodies to distinguish CD34+CD38-CD123+ LSC population and with antibodies against MDR1, BCRP, MDR3, MRP1 or LRP proteins...

Only a small percentage of the separately collected plastic is recycled. The mechanical selection process of source segregated plastic materials generates considerable amounts of residues that are commonly named as Plasmix. By means of a life cycle assessment (LCA) modelling, the environmental performances of the main Plasmix management options (thermal treatment, energy recovery, and landfilling) were compared. Six treatment scenarios, with different pre-treatment alternatives, were evaluated. Landfilling after waste washing and Plasmix substitution of coke in a blast furnace represent the most favorable options, since the performances of thermal treatment and energy recovery are worsened by specific emissions of a variety of toxic compounds and heavy metals within plastic materials as additives...

The treatment of patients in the context of mass casualty incidents (MCI) represents a great challenge for the participating rescue workers and clinics. Due to the increase in terrorist activities it is necessary to become familiar with this new kind of threat to civilization with respect to the medical treatment of victims of terrorist attacks. There are substantial differences between a "normal" MCI and a terrorist MCI with respect to injury patterns (blunt trauma vs. penetrating/perforating trauma), the type and form of the incident (MCI=static situation vs...

Zongwang Ma, Marc Ongena, Monica Höfte
The Pseudomonas- derived cyclic lipopeptide orfamide can induce resistance to Cochliobolus miyabeanus but not to Magnaporthe oryzae in rice. Abscisic acid signaling is involved in the induced systemic resistance response triggered by orfamide. Diverse natural products produced by beneficial Pseudomonas species have the potential to trigger induced systemic resistance (ISR) in plants, and thus may contribute to control of diseases in crops. Some beneficial Pseudomonas spp. can produce cyclic lipopeptides (CLPs), amphiphilic molecules composed of a fatty acid tail linked to an oligopeptide which is cyclized...

In children with newly diagnosed acute myeloid leukaemia (AML), myeloid sarcomas (MS) of the central nervous system (CNS) are rare. Since MS involving the CNS are potentially curable, timely recognition is paramount. Establishing a diagnosis may be problematic as they can easily mimic primary CNS neoplasms. We report the case of a 5-year-old boy with AML with t(8;21)(q22;q22) rearrangement who presented with a massive intracranial MS and rapid clinical deterioration suggestive of a meningioma or a primitive neuroectodermal tumour...
