Input: Consider Input: To investigate whether leukocyte count, fibrinogen, von Willebrand factor (vWF) and plasminogen activator inhibitor-1 activity (PAI-1) are increased in subjects with the metabolic syndrome as defined by the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII) and the World Health Organisation (WHO).', 'Cross-sectional study.', 'A total of 520 overweight and obese subjects: 379 women and 141 men, visiting the weight management clinic of a University Hospital.', 'Waist circumference, triglycerides, HDL cholesterol, blood pressure and fasting glucose were determined, and the presence or absence of the metabolic syndrome according to the NCEP-ATPIII criteria was assessed. In 349 subjects, data on the waist-to-hip ratio (WHR) and albumin excretion rate were available and the WHO criteria were applied. Insulin resistance was defined using the HOMA-IR index.', 'Subjects with the metabolic syndrome according to the NCEP-ATPIII criteria had significantly higher levels of leukocyte count (P < 0.001) and PAI-1 (P < 0.001), while no significant differences were found for fibrinogen or vWF (P > 0.05). Using the WHO criteria, similar results were found except for vWF, where higher levels were found in subjects with the metabolic syndrome. When subjects were classified according to the number of components of the metabolic syndrome, levels of leukocyte count, vWF and PAI-1 activity were significantly different (P < 0.05). In logistic regression analysis PAI-1, gender and leukocyte count were independent determinants of the metabolic syndrome (P < 0.001).

Output: Is among inflammation and coagulation markers , PAI-1 a true component of the metabolic syndrome?


Input: Consider Input: Neisseria meningitidis are common colonizers of the human nasopharynx. In some circumstances, N. meningitidis becomes an opportunistic pathogen that invades tissues and causes meningitis. While a vaccine against a number of serogroups has been in effective use for many years, a vaccine against N. meningitidis group B has not yet been universally adopted. Bacterial heat shock protein complex (HSPC) vaccines comprise bacterial HSPs, purified with their chaperoned protein cargo. HSPC vaccines use the intrinsic adjuvant activity of their HSP, thought to act via Toll-like receptors (TLR), to induce an immune response against their cargo antigens. This study evaluated HSPC vaccines from N. meningitidis and the closely related commensal N. lactamica.', 'The protein composition of N. lactamica and N. meningitidis HSPCs were similar. Using human HEK293 cells we found that both HSPCs can induce an innate immune response via activation of TLR2. However, stimulation of TLR2 or TLR4 deficient murine splenocytes revealed that HSPCs can activate an innate immune response via multiple receptors. Vaccination of wildtype mice with the Neisseria HSPC induced a strong antibody response and a Th1-restricted T helper response. However, vaccination of mice deficient in the major TLR adaptor protein, MyD88, revealed that while the Th1 response to Neisseria HSPC requires MyD88, these vaccines unexpectedly induced an antigen-specific antibody response via a MyD88-independent mechanism.

Output: Do heat shock protein complex vaccines induce antibodies against Neisseria meningitidis via a MyD88-independent mechanism?


Input: Consider Input: The members of the patatin-related phospholipase subfamily III (pPLAIIIs) have been implicated in the auxin response. However, it is not clear whether and how these genes affect plant and cell morphogenesis. Here, we studied the roles of the patatin-related phospholipase pPLAIIIδ in auxin-responsive cell morphology and organ size in Arabidopsis and Brassica napus.', 'We show that overexpression of pPLAIIIδ inhibited longitudinal growth but promoted transverse growth in most organs of Arabidopsis and Brassica napus. Compared to wild-type plants, pPLAIIIδ-KO plants exhibited enhanced cell elongation in hypocotyls, and pPLAIIIδ-OE plants displayed broadened radial cell growth of hypocotyl and reduced leaf pavement cell polarity. For the hypocotyl phenotype in pPLAIIIδ mutants, which resembles the "triple response" to ethylene, we examined the expression of the ACS and ACO genes involved in ethylene biosynthesis and found that ACS4 and ACS5 were up-regulated by 2.5-fold on average in two OE lines compared with WT plants. The endogenous auxin distribution was disturbed in plants with altered pPLAIIIδ expression. pPLAIIIδ-OE and KO plants exhibited different sensitivities to indole-3-acetic acid-promoted hypocotyl elongation in both light and dark conditions. Gene expression analysis of auxin-induced genes in the dark showed that OE plants maintained a higher auxin response compared with WT and KO plants after treatment with 1 μM IAA for 12 h. Following treatment with 10 μM IAA for 30 min in the light, early auxin-induced genes were significantly up-regulated in two OE plant lines.


Output: Does patatin-related phospholipase pPLAIIIδ influence auxin-responsive cell morphology and organ size in Arabidopsis and Brassica napus?
