TL;DR: Findings indicate that N. viridula feeding and oviposition induce leguminous plants to produce blends of volatiles that are characterized by increased amounts of (E)-β-caryophyllene, and these blends attract female T. basalis females.
Abstract: Bean plants (Vicia faba L. and Phaseolus vulgaris L.) damaged by feeding activity of Nezara viridula (L.) (Heteroptera: Pentatomidae), and onto which an egg mass had been laid, produced volatiles that attracted the egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae). Extracts of volatiles of broad bean and French bean plants induced by adults of N. viridula as a result of their feeding activity, oviposition activity, and feeding and oviposition activity combined were analyzed by gas chromatography-mass spectrometry (GC-MS), and tested in Y-tube olfactometer bioassays as attractants for T. basalis females. In extracts from undamaged leguminous plants, green-leaf volatiles were absent or scarcely detected, and monoterpenes and sesquiterpenes were present at trace levels. No significant differences were detected in the profiles of volatiles of undamaged plants, and undamaged plants on which bugs were allowed only to lay eggs. In contrast, feeding and oviposition by adults of N. viridula induced in both leguminous plants a significant increase in terpenoids such as linalool, (E)-beta-caryophyllene, (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene, and (3E)-4,8-dimethyl-1,3,7-nonatriene, which was induced only in French bean plants. Quantitative comparisons revealed increased levels of (E)-beta-caryophyllene in extracts from feeding-damaged plants with N. viridula egg masses compared to feeding-damaged plants without egg masses. In Y-tube olfactometer bioassays, T. basalis females were attracted by extracts of both leguminous plants only when N. viridula adults were allowed to feed and oviposit upon them. Fractionation of extracts of volatiles from broad bean plants with N. viridula feeding damage and egg masses yielded two fractions. but only the fraction containing (E)-beta-caryophyllene was attractive to the egg parasitoid. These findings indicate that N. viridula feeding and oviposition induce leguminous plants to produce blends of volatiles that are characterized by increased amounts of (E)-beta-caryophyllene, and these blends attract female T. basalis. The role of (E)-beta-caryophyllene as a potential synomone for T. basalis is discussed.

TL;DR: In this paper, two different techniques, co-precipitation by citrate method and impregnation with cobalt nitrate of pre-formed ceria and ceria-zirconia oxides, were tested for methane combustion and the catalytic performances were compared with those of a commercial Co3O4.

TL;DR: The N-arylindole 33 was the most potent inhibitor of COX-2 and also the most selective (COX-1/COX2 IC(50) ratio was 262) and the indole derivative 33 was further tested in vivo for its anti-inflammatory activity in rats.
Abstract: Following our previous research on anti-inflammatory drugs (NSAIDs), we report on the design and synthesis of 4-(aryloyl)phenyl methyl sulfones. These substances were characterized for their capacity to inhibit cyclooxygenase (COX-1 and COX-2) isoenzymes. Molecular modeling studies showed that the methylsulfone group of these compounds was inserted deep in the pocket of the human COX-2 binding site, in an orientation that precludes hydrogen bonding with Arg120, Ser353, and Tyr355 through their oxygen atoms. The N-arylindole 33 was the most potent inhibitor of COX-2 and also the most selective (COX-1/COX-2 IC50 ratio was 262). The indole derivative 33 was further tested in vivo for its anti-inflammatory activity in rats. This compound showed greater inhibitory activity than ibuprofen. Other compounds (20, 26, 9, and 30) showed strong activity against carrageenan-induced inflammation. The latter compounds showed a weak capacity to inhibit the proliferation of human cell lines K562, NCI-H460, and HT-29 in vitro.

TL;DR: In this article, the authors compared mortality rates of elderly people with and without asthma and to identify mortality risk factors in those with asthma, 1,233 ambulatory patients aged ≥ 65 years with a diagnosis of asthma or chronic nonrespiratory conditions (n = 1,023) were enrolled in a multicentric study.

TL;DR: The risk of a mother with 21-OH-deficient NCAH for giving birth to a child affected with CAH is 2.5%; at least 14.8% of children born to these mothers have CAH.
Abstract: Context: Because many women with 21-hydroxylase (21-OH)-deficient nonclassic adrenal hyperplasia (NCAH) carry at least one allele affected by a severe mutation of CYP21, they are at risk for giving birth to infants with classic adrenal hyperplasia (CAH). Objective: Our objective was to determine the frequency of CAH and NCAH infants born to mothers with 21-OH-deficient NCAH. Design and Setting: We conducted an international multicenter retrospective/prospective study. Patients and Methods: The outcome of 203 pregnancies among 101 women with 21-OH-deficient NCAH was reviewed. The diagnosis of 21-OH-deficient NCAH was established by a basal or post-ACTH-stimulation 17-hydroxyprogesterone level of more than 10 ng/ml (30.3 nmol/liter). When possible, genotype analyses were performed to confirm CAH or NCAH in the offspring. Results: Of the 203 pregnancies, 138 (68%) occurred before the mother’s diagnosis of NCAH and 65 (32%) after the diagnosis. Spontaneous miscarriages occurred in 35 of 138 pregnancies (25.4%...
