The role of D3-type cyclins is related to cytokinin and the bHLH transcription factor SPATULA in Arabidopsis gynoecium development.

We studied the D3-type cyclin function during gynoecium development in Arabidopsis and how they are related to the hormone cytokinin and the transcription factor SPATULA. Growth throughout the life of plants is sustained by cell division and differentiation processes in meristematic tissues. In Arabidopsis, gynoecium development implies a multiphasic process where the tissues required for pollination, fertilization, and seed development form.

Mesenteric cyst manifested as obesity, gastroesophageal reflux, urinary incontinence, and abdominal mass during pregnancy-Case report and literature review.

Introduction And Importance: The mesenteric cyst (MC) is a rare entity, a benign lesion that causes the growth of an abdominal mass and other clinical presentations. The presentation of MC during pregnancy is even less frequent.

Case Presentation: A 34-year-old Mexican woman presented with a mesenteric cyst treated with laparotomy aspiration during the 16th week of pregnancy; the pregnancy was resolved by cesarean section without problems.

Determinants of COVID-19 Vaccinations among a State-Wide Year-Long Surveillance Initiative in a Conservative Southern State.

By the end of 2021, the COVID-19 pandemic resulted in over 54 million cases and more than 800,000 deaths in the United States, and over 350 million cases and more than 5 million deaths worldwide. The uniqueness and gravity of this pandemic have been reflected in the public health guidelines poorly received by a growing subset of the United States population. These poorly received guidelines, including vaccine receipt, are a highly complex psychosocial issue, and have impacted the successful prevention of disease spread.

Synergistic antiallodynic and antihyperalgesic interaction between L-DOPA and celecoxib in parkinsonian rats is mediated by NO-cGMP-ATP-sensitive K channel.

Pain is a usual and troublesome non-motor symptom of Parkinson's disease, with a prevalence of 29-82%. Therefore, it's vital to find pharmacological treatments for managing PD-associated pain symptoms, to improve patients' quality of life. For this reason, we tested the possible synergy between L-DOPA and celecoxib in decreasing allodynia and hyperalgesia induced by unilateral lesioning with 6-OHDA into the SNpc in rats.

Prevalence of Primary Resistance of Helicobacter pylori to Clarithromycin and Levofloxacin in Southern Spain.

Background: The eradication of Helicobacter pylori (HP) using clarithromycin (CLA)-based triple therapy depends on the resistance of HP to antibiotics. The Maastricht III conference recommends the implementation of locoregional surveillance programmes for primary resistance of HP to CLA. In Andalusia, there are no previous data in this respect.

ERCP during pregnancy.

Background And Aims: ERCP during pregnancy is always challenging for the entire team performing the endoscopic intervention. In this study techniques and different interventional aspects used at several centres about the clinical experience on ERCP in pregnant women are analyzed.

Patients And Methods: the practice on ERCP in pregnant women in six centres during a period of ten years is reported.

Haemodynamic derangement in human immunodeficiency virus-infected patients with hepatitis C virus-related cirrhosis: the role of bacterial translocation.

Background And Aims: Analysis of the influence of the effects of increased intestinal permeability on haemodynamic alterations in human immunodeficiency virus (HIV)-infected patients with decompensated hepatitis C virus (HCV)-related liver disease.

Methods: Forty HIV/HCV co-infected patients and 40 HCV mono-infected patients, 20 of them with compensated cirrhosis and 20 with a previous decompensation, and 20 healthy controls, were studied. Intestinal permeability was determined by serum levels of lipopolysaccharide-binding protein (LBP).

Bacterial translocation in HIV-infected patients with HCV cirrhosis: implication in hemodynamic alterations and mortality.

Objective: Analysis of the influence of portal hypertension on intestinal permeability in HIV-infected patients with hepatitis C virus (HCV)-related cirrhosis and of the prognostic significance of consequent macrophage activation.

Methods: Twenty HIV-monoinfected patients, 70 patients with HIV-HCV coinfection, 20 of them with compensated and 50 with decompensated cirrhosis, and 20 healthy controls were evaluated for intestinal permeability [measured by lipopolysaccharide-binding protein (LBP) serum levels], macrophage activation [soluble CD14, soluble tumour necrosis factor receptor 55 Kd, and interleukin 6 (IL-6)], and activation of the rennin-angiotensin-aldosterone axis. Patients with decompensated cirrhosis were monitored for a median period of 429 days to analyze the prognostic factors implicated in survival.

Hepatocyte growth factor and chronic hepatitis C.

Objective: The hepatocyte growth factor (HGF) is a pleiotropic cytokine produced by hepatic stellate cells and implicated in liver regeneration and fibrosis. Serum levels of HGF vary in liver diseases, reflecting hepatic damage and hepatocellular dysfunction. In this study, serum levels of HGF and the relationship between HGF and biochemical, histological and virological data, have been analysed in patients suffering from chronic hepatitis C (CHC).

Chronic antigenic stimuli as a possible explanation for the immunodepression caused by liver cirrhosis.

The objectives of this work were the analysis of the functional characteristics of circulating monocytes and T lymphocytes in patients with liver cirrhosis, and evaluation of the relationship with an increased exposure to antigens due to bacterial translocation. Forty patients with liver cirrhosis (20 with compensated cirrhosis and 20 with ascitic decompensation) and 20 healthy control subjects were studied. Bacterial translocation was evaluated by serum levels of lipopolysaccharide binding protein (LBP).

Modulation of the anti-inflammatory interleukin 10 and of proapoptotic IL-18 in patients with chronic hepatitis C treated with interferon alpha and ribavirin.

The aim of this work was to analyse apoptosis rate, measured by the serum levels of proapoptotic interleukin (IL)-18 and of soluble Fas (sFas), as well as of anti-inflammatory IL-10, in patients with chronic hepatitis C, at baseline and after treatment with interferon alpha and ribavirin. Twenty-seven patients with biopsy-proven chronic hepatitis C were studied, at baseline and after treatment with interferon alpha (21 cases) or pegylated interferon (6 cases) plus ribavirin. A group of 15 healthy sex- and age-matched individuals was selected as control.

Adhesion molecules as a prognostic marker of liver cirrhosis.

Objective: Endothelial activation plays an active role in modifications of the circulatory status of cirrhotic patients. Soluble endothelial adhesion molecules, induced by pro-inflammatory cytokines, could be considered markers of endothelial activation. Their role in the natural history of cirrhosis and portal hypertension has not been reported.

Implication of inflammation-related cytokines in the natural history of liver cirrhosis.

Background/aims: Increased serum concentrations of pro-inflammatory cytokines have been detected in patients with liver cirrhosis. However, their role in the natural history of cirrhosis and portal hypertension, in the absence of infection, and the prognostic significance of inflammation-related cytokines have not been reported. Our objective was the analysis of the prognostic value of inflammation-related cytokines in cirrhotic patients.

Expression of proinflammatory cytokines and their inhibitors during the course of spontaneous bacterial peritonitis.

The aim of this work was the evaluation, in cirrhotic patients with noninfected ascites and with spontaneous bacterial peritonitis (SBP), of serum and ascitic fluid levels of proinflammatory cytokines [interleukin (IL) 1-beta, tumor necrosis factor alpha (TNF-alpha), and IL6] and antiinflammatory compounds [IL10, soluble IL-1 receptor antagonist (sIL-1Ra), soluble receptors of TNF p55 and p75 (sTNFR55 and sTNFR75), and soluble receptor of IL6 (sIL6R)], as well as their relationship with the outcome of the infection in those with SBP. These molecules were assayed by ELISA in noninfected cirrhotic controls (n = 15), patients with SBP (n = 32), and healthy controls (n = 20). Serum levels of IL6 and of the majority of antiinflammatory mediators, sIL1Ra, sTNFR75, and sIL6R, were higher in control cirrhotic patients compared to healthy subjects.

Serial analysis of serum and ascitic fluid levels of soluble adhesion molecules and chemokines in patients with spontaneous bacterial peritonitis.

The aim of this work was the evaluation of serum and ascitic fluid levels of chemokines (IL-8, growth-regulated oncogene (Gro-alpha), and monocyte chemotactic protein-1 (MCP-1)), and of soluble adhesion molecules (P-selectin, E-selectin, L-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1)) in patients with spontaneous bacterial peritonitis (SBP). These compounds were serially analysed in serum and ascitic fluid by ELISA in patients with SBP (n = 20), non-infected cirrhotic controls (n = 12), and healthy controls (n = 15). Infected and non-infected cirrhotic patients showed significantly higher serum levels of adhesion molecules.

Microbiological characteristics and susceptibility patterns of strains of Rhodotorula isolated from clinical samples.

The members of the genus Rhodotorula show a marked ubiquity. In man, they have been isolated from faeces, nails, skin, sputum, digestive tract and adenoids, forming part of the normal human flora, although in recent years cases have been reported of both local and systemic infection by this yeast. There are virtually no studies in the literature on the sensitivity of this genus to the antifungal agents in common clinical use.

Focal splenic lesions in patients with AIDS: sonographic findings.

Background: The purpose of this study was to describe the sonographic features of the focal splenic lesions in patients with AIDS and to know the frequency and etiology of these features.

Methods: Sonographic exams of 278 AIDS patients were reviewed retrospectively. We recorded the clinical indications for sonograms and sonographic findings of those patients with focal splenic lesions.

[Spontaneous bacterial peritonitis from Campylobacter fetus].

A patient with cirrhosis and ascites who developed spontaneous bacterial peritonitis due to Campylobacter fetus is described herein. This organism has been increasingly associated with bacteremia and localized infections in patients with cirrhosis and other immunocompromised states, but spontaneous bacterial peritonitis has been rarely reported. We review Campylobacter fetus infections and their relationship to development of spontaneous bacterial peritonitis, and we emphasize that prolonged antimicrobial therapy is required.
