BACKGROUND: Three-line Oryza sativa (ssp. japonica) hybrids have been developed mainly using Chinsurah Boro II (BT)-type cytoplasmic male sterility (CMS). The Rf1 gene restores the fertility of BT-type CMS lines, and is the only fertility restorer gene (Rf) that has been used to produce three-line japonica hybrids. Using more Rf genes to breed BT-type restorer lines may broaden the genetic diversity of the restorer lines, and represents a viable approach to improve the heterosis level of BT-type japonica hybrids...

Stigma exsertion, a key determinant of the rice mating system, greatly contributes to the application of heterosis in rice. As few QTLs have been fine mapped or cloned, the genetic architecture of stigma exsertion is quite unclear. We performed genome-wide association study of stigma exsertion and related traits using 6.5 million SNPs characterized in 533 diverse accessions of Oryza sativa. We identified 23 loci significantly associated with stigma exsertion and related traits, three of which were co-located with three major grain size genes GS3, GW5 and GW2...

The inflammasome is a cytoplasmic protein complex that processes interleukins (IL)-1β and IL-18, and drives a form of cell death known as pyroptosis. Oligomerization of this complex is actually the second step of activation, and a priming step must occur first. This involves transcriptional upregulation of pro-IL-1β, inflammasome sensor NLRP3, or the non-canonical inflammasome sensor caspase-11. An additional aspect of priming is the post-translational modification of particular inflammasome constituents...

Gamma-irradiation, particularly an irradiation dose of 50kGy, has been utilised widely to sterilise highly pathogenic agents such as Ebola, Marburg Virus, and Avian Influenza H5N1. We have reported previously that intranasal vaccination with a gamma-irradiated Influenza A virus vaccine (γ-Flu) results in cross-protective immunity. Considering the possible inclusion of highly pathogenic Influenza strains in future clinical development of γ-Flu, an irradiation dose of 50kGy may be used to enhance vaccine safety beyond the internationally accepted Sterility Assurance Level (SAL)...

Neural interfaces hold great promise for research and treatment of a wide variety of neurological diseases. Medical electrodes are designed to interface with the nervous system and provide control signals for neural prostheses. We fabricated previously a hook-up neural electrode. Here we investigate the in vitro cytotoxicity of three commercial carbon pastes used for printing the conductor tracks of this electrode. At first, the carbon pastes were characterized with respect to their microstructure and chemical composition...

To examine the relationship of impairments of the liver and kidney with viral load after nephropathogenic infectious bronchitis virus (NIBV) infection in embryonic chickens, 120 specific-pathogen-free Leghorn embryonated chicken eggs were randomly divided into two groups (infected and control), with three replicates per group and 20 eggs in each replicate. The eggs in the infected and control groups were challenged with 0.2 mL of 10(5.5) ELD50 NIBV and sterile saline solution, respectively. The embryonic chickens' plasma and liver and kidney tissues were collected at 1, 3, and 5 days post-inoculation (dpi), the liver and kidney functional parameters were quantified, and the tissue viral loads were determined with real-time PCR...

Resin Yttrium-90 (Y90) microspheres have historically been infused using sterile water (H2O). In 2013, recommendations expanded to allow delivery with 5% dextrose in water (D5W). In this retrospective study, we hypothesized that D5W would improve Y90 delivery with a lower incidence of stasis. We reviewed 190 resin Y90 infusions using H2O (n=137) or D5W (n=53). Y90 dosimetry was calculated using the body surface area method. Infusion was halted if intra-arterial stasis was fluoroscopically identified prior to clearing the vial...

Deep vein thrombosis (DVT) with its major complication, pulmonary embolism, is a global health problem. Mechanisms of DVT remain incompletely understood. Platelets play a role in DVT but the impact of specific platelet receptors remains unclear. Platelet C-type lectin-like receptor 2 (CLEC-2) is known to maintain the physiological state of blood vasculature under inflammatory conditions. DVT is a thromboinflammatory disorder developing largely as sterile inflammation in the vessel wall. We hypothesized therefore that CLEC-2 might play a role in DVT...

BACKGROUND: Through experience it has been accepted that bile in normal conditions remains sterile. Bactibilia is a common finding in individuals at high risk or with complicated cholecystolithiasis, however few data prevails about the prevalence of bactibilia in patients operated on for uncomplicated laparoscopic cholecystectomy. There is s common usage of preoperative and postoperative antibiotics in the different patients without the existence of any actual bacteriologic and epidemiologic evidence...

Ultradeformable archaeosomes (UDA) are nanovesicles made of total polar archaeolipids (TPA) from the archaea Halorubrum tebenquichense, soybean phosphatidylcholine and sodium cholate (3:3:1w/w). Fresh dispersions of UDA including different type of antigens are acknowledged as efficient topical vaccination agents. UDA dispersions however, if manufactured for pharmaceutical use, have to maintain colloidal stability upon liposomicidal processes such as sterilization and lyophilization (SLRUDA), needed to extend shelf life during storage...

OBJECTIVE: Surgical site infections (SSIs) are serious postoperative complications that may lead to undesired patient outcomes. Previous research has used survey and chart audit methods to describe wound care practices. However, little research has been published using contemporaneous observations to describe the surgical wound management practices of nurses. The aim of this study was to prospectively describe surgical nurses' postoperative wound care practices and the extent to which observed surgical wound practices aligned with evidence-based guideline recommendations...

: Spermatogenesis is a complex process of proliferation and differentiation during male germ cell development whereby undifferentiated spermatogonial germ cells evolve into maturing spermatozoa. In this developmental process the interactions between different cell types are finely regulated, hence any disruption in these relationships leads to male infertility. The twitcher mouse, the murine model of Krabbe disease, is characterized by deficiency of galactosylceramidase, an enzyme also involved in the metabolism of the galactosyl-alkyl-acyl-glycerol, the precursor of sulfogalactosyl-alkyl-acyl-glycerol, the most abundant glycolipid in spermatozoa...

OBJECTIVES: To assess the long-term outcomes (>4 years) following combined surgical resective/regenerative therapy of advanced peri-implantitis lesions using two surface decontamination methods. MATERIAL & METHODS: Fifteen patients (n = 15 combined supra- and intrabony defects) completed a follow-up observation period of 7 years. The treatment procedure included access flap surgery, granulation tissue removal and implantoplasty at buccally and supracrestally exposed implant parts, and a randomly assigned decontamination of the unmodified intrabony implant surface areas using either (i) an Er:YAG laser (ERL) or (ii) plastic curettes + cotton pellets + sterile saline (CPS)...

OBJECTIVES: Saliva can suppress osteoclastogenesis, but the underlying mechanism has not been discovered yet. Considering that endotoxins suppress osteoclastogenesis in bone marrow cultures and that saliva contains endotoxins, it was reasonable to hypothesize that the impact of saliva on osteoclastogenesis requires toll-like receptor 4 signaling. MATERIAL AND METHODS: To test this hypothesis, we blocked toll-like receptor 4 signaling with TAK-242 in the presence of saliva in murine bone marrow cultures...

The aim of this study was to investigate scientific articles in three German journals for national socialist and racist contents. The three journals evaluated for the period of the Third Reich were the Der Nervenarzt, Deutsche Zeitschrift für Nervenheilkunde and the Archiv für Psychiatrie und Nervenkrankheiten. The specialist disciplines of neurology and psychiatry were united in the year 1935 and Ernst Rüdin, a neurological geneticist, was appointed as president (Reichsleiter) of the society. The universal idea of a degenerative development, which was believed to exert a negative influence on public health, was widely accepted in this time period; therefore, in some articles measures were called for, such as termination of pregnancy, sterilization and castration of diseased people and also of criminals...
