Sambandet mellan psykisk ohÀlsa och hÀlsorelaterade levnadsvanor bland kvinnor och mÀn i en skÄnsk befolkning
Bakgrund: Daglig rökning och lÄg fysisk aktivitet pÄ fritiden Àr betydligt högre bland individer med psykisk ohÀlsa.
Syfte: Att undersöka dessa samband i ett köns- och socioekonomiskt perspektiv, samt eventuellt finna bakomliggande orsaker.
Metod: AnvÀnder data frÄn en tvÀrsnittsstudie (FolkhÀlsoenkÀt, SkÄne 2000) med en representativ population (n = 11 304) i Äldern 18-65. Huvudvariabler Àr sjÀlvrapporterad daglig rökning och lÄg fysisk aktivitet, samt psykisk ohÀlsa som bedöms via General Health Questionnaire-12. Analyser gjordes med logistisk
regression för att fÄ oddskvoter och kontrollera för möjliga confounders.
Resultat: Samband finns mellan psykisk ohÀlsa och daglig rökning, respektive lÄg fysisk aktivitet bland bÄda könen, och bland socioekonomiska grupper. Kvinnor har signifikant lÀgre oddskvoter gÀllande bÄda sambanden. Individer med psykisk ohÀlsa har fler ofördelaktiga levnadsvanor Àn de med ej psykisk ohÀlsa, oavsett socioekonomisk status. Ingen signifikant skillnad upptÀcktes mellan socioekonomiska grupper vid jÀmförelse av oddskvoter gÀllande lÄg fysisk aktivitet, bland kvinnor med ej psykisk ohÀlsa.
Slutsatser: Studien har bekrÀftat sambandet psykisk ohÀlsa och daglig rökning, respektive lÄg fysisk aktivitet, bland bÄda könen och inom olika socioekonomiska grupper.Title: The relationship between mental ill-health and health related lifestyle habits among women and men in a scanian population
Background: Daily smoking and low leisure time physical activity prevalence are higher among individuals with mental ill-health.
Aim: To investigate these relationships in a gender- and socioeconomic perspective, together with possible underlying mechanisms.
Methods: Using data from a cross-sectional survey (Scania public health survey, 2000) with a representative sample (n = 11 304), aged 18-65. Included were selfreported daily smoking, low leisure time physical activity, and mental health measured by the General Health Questionnaire-12. Logistic regression analyses
were performed to get odds ratios (OR), and to adjust for potential confounding factors.
Results: Daily smoking and low leisure time physical activity were found to be associated with mental ill-health, among both sexes. Women had significantly lower OR than men with regard to both relationships. Individuals with mental illhealth had more unfavourable lifestyle habits than individuals without, independently of socioeconomic status. There were no significant differences between socioeconomic groups when comparing OR for low leisure time physical
activity among women without mental ill-health.
Conclusions: This study confirms the relationships of mental ill-health and daily
smoking, and low leisure time physical activity, among both sexes and within different socioeconomic groups.

8âFunctionalization of Alkyl-Substituted-3,8-Dimethyl BODIPYs by Knoevenagel Condensation
New 8-alkenylBODIPYs have been synthesized by Knoevenagel condensation between a series of alkyl-substituted-3,8-dimethylBODIPYs and aromatic or aliphatic aldehydes. This is in clear contrast with literature precedents, which indicate that this reaction occurs exclusively on the methyl group at C-3. The change in hybridization of the carbon at the 8-position (from sp<sup>3</sup> to sp<sup>2</sup>) determines the fluorescence emission of the BODIPY, while the presence of electron-donating or -withdrawing groups leads to intramolecular charge transfer processes

Selective Lateral Lithiation of Methyl BODIPYs: Synthesis, Photophysics, and Electrochemistry of New <i>Meso</i> Derivatives
Selected <i>meso</i> BODIPYs (chemically reactive, difficult
to obtain by established procedures, or photophysically or electrochemically
attractive) have been obtained by unprecedented selective lateral
lithiation of 8-methylBODIPYs. The physical study of the obtained
new <i>meso</i> BODIPYs reveals interesting tunable properties
related to the activation of intramolecular charge-transfer processes,
endorsing the new synthetic methodology as useful for the development
of smarter BODIPY dyes for technological applications
End-to-End Automated Synthesis of C(sp<sup>3</sup>)âEnriched Drug-like Molecules <i>via</i> Negishi Coupling and Novel, Automated LiquidâLiquid Extraction
Herein, we report an end-to-end process including synthesis,
work-up,
purification, and post-purification with minimal human intervention
using Negishi coupling as a key transformation to increase Fsp3 in bioactive molecules. The main advantages of this protocol
are twofold. First, the automated sequential generation of organozinc
reagents from readily available alkyl halides offers a large diversity
of alkyl groups to functionalize (hetero)aryl halide scaffolds via Pd-catalyzed Negishi coupling in continuous flow. Second,
a fully automated liquidâliquid extraction has been developed
and successfully applied for unattended operations. The workflow was
completed with mass-triggered preparative high-performance liquid
chromatography HPLC, providing an efficient production line of compounds
with enriched sp3 character and better drug-like properties.
The modular nature allows a smooth adaptation to a wide variety of
synthetic methods and protocols and makes it applicable to any medchem
laboratory
Using Inclusion Complexes with Cyclodextrins To Explore the Aggregation Behavior of a Ruthenium Metallosurfactant
The
aggregation behavior of a chiral metallosurfactant, bisÂ(2,2âČ-bipyridine)Â(4,4âČ-ditridecyl-2,2âČ-bipyridine)ÂrutheniumÂ(II)
dichloride (Ru<sub>2</sub><sup>4</sup>C<sub>13</sub>), synthesized
as a racemic mixture was characterized by small-angle neutron scattering,
light scattering, NMR, and electronic spectroscopies. The analysis
of the SANS data indicates that micelles are prolate ellipsoids over
the range of concentrations studied, with a relatively low aggregation
number, and the micellization takes place gradually with increasing
concentration. The presence of cyclodextrins (ÎČ-CD and Îł-CD)
induces the breakup of the micelles and helps to establish that micellization
occurs at a very slow exchange rate compared to the NMR time scale.
The open structure of this metallosurfactant enables the formation
of very stable complexes of 3:1 stoichiometry, in which one CD threads
one of the hydrocarbon tails and two CDs the other, in close contact
with the polar head. The complex formed with ÎČ-CD, more stable
than the one formed with the wider Îł-CD, is capable of resolving
the Î and Î enantiomers at high CD/surfactant molar ratios.
The chiral recognition is possible due to the very specific interactions
taking place when the ÎČ-CD coversîžvia its secondary rimîžpart
of the diimine moiety connected to the hydrophobic tails. A SANS model
comprising a binary mixture of hard spheres (complex + micelles) was
successfully used to study quantitatively the effect of the CDs on
the aggregation of the surfactant
In Search of the Perfect Photocage: StructureâReactivity Relationships in <i>meso</i>-Methyl BODIPY Photoremovable Protecting Groups
A detailed investigation of the photophysical
parameters and photochemical
reactivity of <i>meso</i>-methyl BODIPY photoremovable protecting
groups was accomplished through systematic variation of the leaving
group (LG) and core substituents as well as substitutions at boron.
Efficiencies of the LG release were evaluated using both steady-state
and transient absorption spectroscopies as well as computational analyses
to identify the optimal structural features. We find that the quantum
yields for photorelease with this photocage are highly sensitive to
substituent effects. In particular, we find that the quantum yields
of photorelease are improved with derivatives with higher intersystem
crossing quantum yields, which can be promoted by core heavy atoms.
Moreover, release quantum yields are dramatically improved by boron
alkylation, whereas alkylation in the <i>meso</i>-methyl
position has no effect. Better LGs are released considerably more
efficiently than poorer LGs. We find that these substituent effects
are additive, for example, a 2,6-diiodo-<i>B</i>-dimethyl
BODIPY photocage features quantum yields of 28% for the mediocre LG
acetate and a 95% quantum yield of release for chloride. The high
chemical and quantum yields combined with the outstanding absorption
properties of BODIPY dyes lead to photocages with uncaging cross sections
over 10âŻ000 M<sup>â1</sup> cm<sup>â1</sup>, values
that surpass cross sections of related photocages absorbing visible
light. These new photocages, which absorb strongly near the second
harmonic of an Nd:YAG laser (532 nm), hold promise for manipulating
and interrogating biological and material systems with the high spatiotemporal
control provided by pulsed laser irradiation, while avoiding the phototoxicity
problems encountered with many UV-absorbing photocages. More generally,
the insights gained from this structureâreactivity relationship
may aid in the development of new highly efficient photoreactions
