Anna Kalinka, Magdalena Achrem
The analysis of early generations of triticale showed numerous rearrangements of the genome. Complexed transformation included loss of chromosomes, t-heterochromatin content changes and the emergence of retrotransposons in new locations. This study investigated certain aspects of genomic transformations in the early generations (F5 and F8) of the primary octoploid triticale derived from the cross of hexaploid wheat with the diploid rye. Most of the plants tested were hypoploid; among eliminated chromosomes were rye chromosomes 4R and 5R and variable number of wheat chromosomes...

BACKGROUND: Autologous platelet-rich plasma (PRP) is widely used for a variety of clinical applications. However, clinical outcome studies have not consistently shown positive effects. The composition of PRP differs based on many factors. An improved understanding of factors influencing the composition of PRP is important for the optimization of PRP use. HYPOTHESIS: Age and sex influence the PRP composition in healthy patients. STUDY DESIGN: Controlled laboratory study...

Orthobiologics such as autologous conditioned serum (ACS) are often used to treat joint disease in horses. Because ACS is generated from the horse's own blood, any medication administered at the time of preparation would likely be present in stored ACS, which could lead to an inadvertent positive drug test following intra-articular (IA) injection. The main objective of this study was to determine if ACS prepared from firocoxib positive horses could result in detectable plasma concentrations of the drug following IA injection...

Antigen cross-presentation by dendritic cells (DC) stimulates cytotoxic T cell activation to promote immunity to intracellular pathogens, viruses and cancer. Phagocytosed antigens generate potent T cell responses, but the signalling and trafficking pathways regulating their cross-presentation are unclear. Here, we show that ablation of the store-operated-Ca2+-entry regulator STIM1 in mouse myeloid cells impairs cross-presentation and DC migration in vivo and in vitro. Stim1 ablation reduces Ca2+ signals, cross-presentation, and chemotaxis in mouse bone-marrow-derived DCs without altering cell differentiation, maturation or phagocytic capacity...

The study investigated how conflicting stimulus-response mappings influenced affordance processing given a manipulation of the functional relations. Participants performed a task involving consistent-inconsistent stimulus-response mappings: Implicit Relational Assessment Procedure (IRAP). They were instructed to confirm or to deny a relation between words and tool-objects (consistent blocks) or to provide non-conventional responses (inconsistent blocks). The relations between stimuli could functionally match (e...

Currently, very few studies are available on the expression of CXCR1 in mouse macrophages having both intact TNFR1 and IL-1R or their deficiency in relation to acute S. aureus infection. Peritoneal macrophages from mice neutralized singly for TNFR1or IL-1R, or for both TNFR1 and IL-1R were infected with S. aureus in vitro and their ability to secrete cytokines and reactive oxygen species (ROS) were determined. It was observed that the release TNF-α and IL-1β in response to S. aureus infection was decreased in macrophages when both TNFR1 and IL-1R were neutralized...

Recurrent acute pancreatitis (RAP) is defined based on the occurrence of two or more episodes of acute pancreatitis. The initial evaluation fails to detect the cause of RAP in 10%-30% of patients, whose condition is classified as idiopathic RAP (IRAP). Idiopathic acute pancreatitis (IAP) is a diagnostic challenge for gastroenterologists. In view of associated morbidity and mortality, it is important to determine the aetiology of pancreatitis to provide early treatment and prevent recurrence. Endoscopic ultrasound (EUS) is an investigation of choice for imaging of pancreas and biliary tract...

σ(S) is an alternative sigma factor, encoded by the rpoS gene, that redirects cellular transcription to a large family of genes in response to stressful environmental signals. This so-called σ(S) general stress response is necessary for survival in many bacterial species and is controlled by a complex, multifactorial pathway that regulates σ(S) levels transcriptionally, translationally, and post-translationally in Escherichia coli It was shown previously that the transcription factor DksA and its cofactor ppGpp are among the many factors governing σ(S) synthesis, thus playing an important role in activation of the σ(S) stress response...

LVV-hemorphin-7 (LVV-h7) is bioactive peptide resulting from degradation of hemoglobin β-globin chain. LVV-h7 is a specific agonist of angiotensin IV receptor. This receptor belongs to the class of insulin-regulated aminopeptidases (IRAP), which displays oxytocinase activity. Herein, our aims were to assess whether: i) LVV-h7 modifies centrally organized behavior and cardiovascular responses to stress and ii) mechanisms underlying LVV-h7 effects involve activation of oxytocin (OT) receptors, probably as result of reduction of IRAP proteolytic activity upon OT...

Natural killer (NK) cells are considered a promising strategy for cancer treatment. Various methods for large-scale NK cell expansion have been developed, but they should guarantee that no viable cells are mixed with the expanded NK cells because most methods involve cancer cells or genetically modified cells as feeder cells. We used an anti-CD16 monoclonal antibody (mAb) and irradiated autologous peripheral blood mononuclear cells (PBMCs) (IrAPs) to provide a suitable environment (activating receptor-ligand interactions) for the NK cell expansion...

Argan Tree is well known for its precious oil extracted from its seeds particularly used for the nutritional and cosmetic benefits. Because of the high international demand, the argan tree suffers from overexploitation and its cultivation is rare. Thus, the assessment of the genetic variation of this endemic tree is critically important for designing conservation strategies. In the present study and for the first time, genetic diversity of the global natural distribution of argan tree (Argania spinosa L.) in Morocco was assessed...

BACKGROUND: Increased Oxidative Stress (OS) is implicated in the pathogenesis of Chronic Pancreatitis (CP). Whether or not OS contributes to disease progression through the stages of Recurrent Acute Pancreatitis(RAP), to CP is not known. Increased OS, if present in RAP could be an important therapeutic target in preventing progression of RAP to CP. OBJECTIVE: To assess the oxidative stress and antioxidant status in patients with idiopathic RAP. METHODS: 50 consecutive patients with Idiopathic Recurrent Acute Pancreatitis (IRAP) were included...

In search for RNA signals that modulate transcription via direct interaction with RNA polymerase (RNAP), we deep sequenced an E. coli genomic library enriched for RNAP-binding RNAs. Many natural RNAP-binding aptamers, termed RAPs, were mapped to the genome. Over 60% of E. coli genes carry RAPs in their mRNA. Combining in vitro and in vivo approaches, we characterized a subset of inhibitory RAPs (iRAPs) that promote Rho-dependent transcription termination. A representative iRAP within the coding region of the essential gene, nadD, greatly reduces its transcriptional output in stationary phase and under oxidative stress, demonstrating that iRAPs control gene expression in response to changing environment...

The renin-angiotensin system (RAS) is undisputedly one of the most prominent endocrine (tissue-to-tissue), paracrine (cell-to-cell) and intracrine (intracellular/nuclear) vasoactive systems in the physiological regulation of neural, cardiovascular, blood pressure, and kidney function. The importance of the RAS in the development and pathogenesis of cardiovascular, hypertensive and kidney diseases has now been firmly established in clinical trials and practice using renin inhibitors, angiotensin-converting enzyme (ACE) inhibitors, type 1 (AT1) angiotensin II (ANG II) receptor blockers (ARBs), or aldosterone receptor antagonists as major therapeutic drugs...

The vasotocin/vasopressin and isotocin/mesotocin/oxytocin family of nonapeptides regulate social behaviors and physiological functions associated with reproductive physiology and osmotic balance. While experimental and correlative studies provide evidence for these nonapeptides as modulators of behavior across all classes of vertebrates, mechanisms for nonapeptide inactivation in regulating these functions have been largely overlooked. Leucyl-cystinyl aminopeptidase (LNPEP) - also known as vasopressinase, oxytocinase, placental leucine aminopeptidase (P-LAP), and insulin-regulated aminopeptidase (IRAP) - is a membrane-bound zinc-dependent metalloexopeptidase enzyme that inactivates vasopressin, oxytocin, and select other cyclic polypeptides...

Di-(2-ethyl hexyl) phthalate (DEHP) is the plasticizer used in variety of medical and consumer products to impart structural flexibility. DEHP and its primary metabolite mono-(2-ethyl hexyl)phthalate (MEHP) posed a considerable interest because of their contribution to insulin resistance, type-2 diabetes and obesity. Experimental and epidemiological data have shown that DEHP affects blood glucose homeostasis. However, direct effect of DEHP and its metabolite MEHP on insulin signal transduction and glucose transporter 4 (GLUT4) translocation remain obscure...

Currently, study of the inter and the intra-population genetic disparity was done by use of the 200 Olea europaea L. which is found growing naturally in the nation of Iran, and this study was carried out by AFLP and IRAP markers. The fingerprints that were similar to the AFLP and the IRAP markers were evidence of high concentrations of heterozygosity and this shows that O. europaea L. is primarily the out crossing species. The average percentage of polymorphism is as shown below: 87.15 and 87.38% of the information used in regard to the AFLP and the IRAP, respectively...
