Disentangling the trajectories of maternal depressive symptoms and partnership problems in the transition to parenthood and their impact on child adjustment difficulties.

Maternal perinatal depression (PND) and partnership problems have been identified to influence the development of later child adjustment difficulties. However, PND and partnership problems are closely linked which makes it difficult to draw conclusions about the exact transmission pathways. The aim of the present study was to investigate to what extent PND symptoms and partnership problems influence each other longitudinally and to examine the influence of their trajectories on child adjustment difficulties at the age of three. Analyses were based on publicly available data from the German family panel "pairfam". N = 354 mothers were surveyed on depressive symptoms and partnership problems annually from pregnancy (T0) until child age three (T4). Child adjustment difficulties were assessed at age three. Results of latent change score modeling showed that partnership problems predicted change in PND symptoms at T0 and T3 while PND symptoms did not predict change in partnership problems. Child adjustment difficulties at age three were predicted by PND symptoms, but not by partnership problems. Partnership problems predicted externalizing, but not internalizing symptoms. Results underline the effects of family factors for the development of child adjustment difficulties and emphasize the importance of early interventions from pregnancy onwards.

Diethyl 1-(p-fluorophenyl)-5-oxo-3-(2-thienyl)pyrrolidine-2,2-dicarboxylate.

In the title compound, C20H20FNO5S, the pyrrolidine ring adopts an envelope conformation. The fluorophenyl and thiophene rings are individually planar. The molecular and crystal structures are stabilized by intra- and intermolecular C-H...O interactions.

Studies on the synthesis of trans-dihydrodiols of polycyclic aromatic thiaarenes as potential proximate carcinogenic metabolites: first synthesis of trans-10,11-dihydroxy-10,11-dihydroacenaphtho[1, 2-b]benzo[d]thiophene and 6,7-dihydroxy-6,7-dihydronaphtho[1, 2-b]thiophene.

Polyaromatic thiophene compounds are found to occur concomitantly with numerous coal-derived products and shale oils and are suspected mutagens and/or carcinogens. The first synthesis of the two title compounds 9 and 16 has been achieved in five or four steps starting from 8,9-dihydroacenaphtho[1,2-b]benzo[d]thiophene (1) and 7-methoxynaphtho[1,2-b]thiophene (12), respectively. Compound 1 was converted to the cis-diol (11) (via treatment with OsO(4)/pyridine) or to trans-diol (3) [via Prevost reaction (PhCOOAg/I(2)) followed by hydrolysis] in 95-98% yield, respectively. Subsequent dehydration (PTS/benzene) of the diol followed by aromatization of the resulting ketone (5) produced the phenolic compound 6 in 97% yield. Oxidation of the phenol with phenyl iododiacetate followed by hydrolysis of the o-quinone monoketal 7 gave the o-quinone (8) in 86% yield. Stereoselective reduction of 8 with NaBH(4)/EtOH under oxygen afforded trans-10,11-dihydroxy-10,11-dihydroacenaphtho[1,2-b]benzo[d]thi oph ene(9) (orange yellow solid) in 55% yield. Compound 16 was obtained as a colorless solid, through the stereoselective reduction of the o-quinone 15 (with NaBH(4)), which in turn was prepared from 12 following the protocol of functional group transformation of methoxy --> phenol --> o-quinone monoketal --> o-quinone, as used in the previous case. The yields for all the steps are very good. The mutagenicity assay of compound 9 and 16 as well as their parent thiaarenes have been performed. The results showed that 9 may not be the proximate carcinogen of acenaphtho[1,2-b]benzo[d]thiophene, while it is likely that compound 16 is one of the possible proximate carcinogens for naphtho[1,2-b]thiophene.

Synthesis of some thieno gamma lactam monocarboxylic acids with high antibacterial activity: a new look at an old molecular system.

Synthesis and antibacterial activity of some novel monocyclic thienyl gamma lactams are reported. The compounds have been synthesized by a two-step process consisting of, first, intermolecular Michael addition, followed by intramolecular amidification between suitable arylamino malonate and 3-(2'-thienyl) acryloyl chloride and then hydrolysis cum in situ decarboxylation of the diacid. The compounds showed moderate to high antibacterial activity against gram positive and gram negative bacteria.

Structurally designed novel furogamma lactams as inhibitors for bacterial propagations.

Some novel furogamma lactams have been synthesised by one step condensation of arylaminomalonates with substituted furyl acryloyl chlorides. The annulation of substituted monocyclic gammalactams followed by cyclization produced novel tricyclic furogamma lactams. Some of these furogammalactams are found to exhibit Gram-positive and Gram-negative antibacterial activity at very high concentrations.

A profile of mood in ambulatory nursing home residents.

This study examined mood in 54 ambulatory nursing home residents. Female subjects reported significantly lower scores on the Anger-Hostility subscale than either men or normative subjects. Women also scored lower than normative subjects on the Vigor-Activity and Confusion-Bewilderment subscales, whereas men scored lower on the Fatigue-Inertia subscale. Both men and women reported below norm scores for the Tension-Anxiety subscale. Further study is needed to identify sociological factors that may explain diminished expression of mood in this vulnerable population, and to compare these findings with the mood profile of community dwelling elders.

Assessment of the mutagenic activity of some acenaphtho(1,2-b)quinolines.

The mutagenic activity of four substituted acenaphtho(1,2-b)quinolines were evaluated using the Ames test (Salmonella assay). The compounds tested were acenaphtho(1,2-b)quinoline (1) and its 10-methoxy (2), 10-methyl (3) and 10-nitro (4) derivatives. Compounds 1 and 3 were found to be non-mutagenic, but compound 2 was found to be mutagenic with metabolic activation only. However, compound 4 was found to be very active with or without activation.
