Brucellosis is one of the leading causes of abortion in domestic animals that imposes costs on both economy and society. The disease is highly zoonotic and poses risk to animal handlers due to its zoonotic nature. It causes stillbirth, loss of kids and abortion in last term of pregnancy. Reproductive damage includes infertility in does and orchitis and epididymitis in breeding bucks, which result in high financial losses to farmers and the agriculture industry as a whole. It requires highly sensitive and specific assays to diagnose the disease at field level...

In vitro technologies provide the capacity to study drug metabolism where in vivo studies are precluded due to ethical or financial constraints. The metabolites generated by in vitro studies can assist anti-doping laboratories to develop protocols for the detection of novel substances that would otherwise evade routine screening efforts. In addition, professional bodies such as the Association of Official Racing Chemists (AORC) currently permit the use of in vitro derived reference materials for confirmation purposes providing additional impetus for the development of cost effective in vitro metabolism platforms...

Three-dimensional bioprinting has emerged as a promising solution for the freeform fabrication of living cellular constructs, which can be used for tissue/organ transplantation and tissue models. During bioprinting, some living cells are unavoidably injured and may become necrotic or apoptotic cells. This study aims to investigate the printing-induced cell injury and evaluates injury types of post-printing cells using the annexin V/7-aminoactinomycin D and FAM-DEVD-FMK/propidium iodide assays during laser printing of NIH 3T3 mouse fibroblasts...

A gram-staining negative, non-motile, aerobic chemoheterotrophic, ovoid or short rod-shaped bacterium, designated as J89(T), was isolated from a seawater sample collected from the coast of Yellow Sea in Qingdao, China. The strain grew at salinities of 1.0-6.0% (w/v) NaCl (optimum, 3.0%). Growth occurred at pH 6.0-9.0 (optimum, pH 7.0) and at 10-35 °C (optimum, 25-30 °C). The genomic DNA G+C content was determined to be 59.3 mol%. Q-8 was detected as the respiratory quinone. The major fatty acids (>10%) were summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), and C16:0...

BACKGROUND: Gregarines are a group of early branching Apicomplexa parasitizing invertebrate animals. Despite their wide distribution and relevance to the understanding the phylogenesis of apicomplexans, gregarines remain understudied: light microscopy data are insufficient for classification, and electron microscopy and molecular data are fragmentary and overlap only partially. METHODS: Scanning and transmission electron microscopy, PCR, DNA cloning and sequencing (Sanger and NGS), molecular phylogenetic analyses using ribosomal RNA genes (18S (SSU), 5...

Colonic perforation due to impacted faeces or faecaloma is a relatively uncommon presentation with grave prognosis. If left untreated, it can be life threatening due to complications like faecal peritonitis. Till date, fewer than 150 cases have been reported mostly in the English surgical literature describing constipation as the most common underlying etiology. Involvement of rectum is rare with very limited data published in this context. We present a case of stercoral perforation involving the rectum with associated faecal peritonitis and pneumatosis coli...

The genus Kraken represents a distinct lineage of filose amoebae within the Cercozoa. Currently a single species, Kraken carinae, has been described. SSU rDNA phylogeny showed an affiliation to the Cercomonadida, branching with weak support at its base, close to Paracercomonas, Metabolomonas, and Brevimastigomonas. Light microscopical analyses showed several unique features of the genus Kraken, but ultrastructure data were lacking. In this study, K. carinae has been studied by electron microscopy, these data conjoined with a two-gene phylogeny were used to give more insight into the evolutionary relationship of the genus Kraken within Cercozoa...

The genus Thiobacillus comprises four species with validly published names, of which Thiobacillus aquaesulis DSM 4255T (=ATCC 43788T) is the only species that can grow heterotrophically or mixotrophically - the rest being obligate autotrophs - and has a significant metabolic difference in not producing tetrathionate during the oxidation of thiosulfate during autotrophic growth. On the basis of this and differential chemotaxonomic properties and a 16S rRNA gene sequence similarity of 93.4 % to the type species Thiobacillus thioparus DSM 505T, we propose that it is moved to a novel genus, Annwoodia gen...

Acute lymphoblastic leukemia is the most common malignancy in children. Patient improvement completely depends on the diagnosis of acute lymphoblastic leukemia. So there is a great demand for diagnosis of acute lymphoblastic leukemia. In this study, a novel assay based on dual-aptamer (Sgc8c and ATP aptamers)-functionalized graphene oxide (DAFGO) complex was designed for the identification of Molt-4 cells (human acute lymphoblastic leukemia T-cell). This assay relies on the internalization of DAFGO complex into Molt-4 cells, but not into U266 cells, using Sgc8c aptamer as molecular recognition probe, and release of FAM-labeled ATP aptamer from the complex in the presence of high amounts of ATP in lysosome, leading to a strong fluorescence emission...

Species-specific lateral flow dipstick (LFD) assays for the identification of Atlantic cod (Gadus morhua), Pacific cod (Gadus macrocephalus), Alaska pollock (Gadus chalcogrammus) and ling (Molva molva) in food products were developed. The method comprises a PCR system with four sets of specific primers, for each target species. This step was also devised to dual-labeling of PCR products with biotin and 6-FAM, which are then easily read on a lateral flow dipstick, upon which these products are immobilized by a fixed biotin-ligand and visualized with anti-FAM antibody-coated gold nanoparticles...

Microsatellite DNA can provide more detailed population genetic information than mitochondrial DNA which is normally used to research ancient bone. The methods detailed in this chapter can be utilized for any type of bone. However, for this example, four microsatellite loci were isolated from Steller's sea cow (Hydrodamalis gigas) using published primers for manatee and dugong microsatellites. The primers DduC05 (Broderick et al., Mol Ecol Notes 6:1275-1277, 2007), Tmakb60, TmaSC5 (Pause et al., Mol Ecol Notes 6: 1073-1076, 2007), and TmaE11 (Garcia-Rodriguez et al...

Although testate amoebae have attracted great interest of protistologists for more than a century, some groups, especially those with a hyaline, organic test (=theca) are still poorly known. One of those is the genus Lecythium Hertwig et Lesser, 1874. Only recently Lecythium spp. were characterized by morphological and molecular means, but data on the type species Lecythium hyalinum Hertwig et Lesser, 1874, was still lacking. In this study, we screened for L. hyalinum in freshwater samples of Germany and the Netherlands...

Arindam Das, Jin Qian, William Y Tsang
Ciliogenesis is a fundamental biological process central to human health. Precisely how this process is coordinated with the cell cycle remains an open question. We report that nephrocystin-5 (NPHP5/IQCB1), a positive regulator of ciliogenesis, is a stable and low turnover protein subjected to cycles of ubiquitination and deubiquitination. NPHP5 directly binds to a deubiquitinating enzyme USP9X/FAM and two E3 ubiquitin ligases BBS11/TRIM32 and MARCH7/axotrophin. NPHP5 undergoes K63 ubiquitination in a cell cycle dependent manner and K48/K63 ubiquitination upon USP9X depletion or inhibition...

The common cancer treatment strategies like chemotherapy and radiotherapy are nonspecific and can trigger severe side effects by damaging normal cells. So, targeted cancer therapies, such as apoptosis induction, have attracted great attention in recent years. In this project, two nano-complexes, MUC1 aptamer-NAS-24 aptamer-Graphene oxide (GO) and MUC1 aptamer-Cytochrome C aptamer-GO, were designed to induce cell programmed death in MDA-MB-231 and MCF-7 cells (breast cancer cell lines) and to verify the level of apoptosis in both cell lines...
