The Estimation of Acidic Behavior of Wood by Treatment with Aqueous Na2HPO4 Solution
As a new approach, the acidity that wood exhibits under moderate conditions is assayed by stimulated dissociation of weak wood acids in lightly basic secondary phosphate solutions. To assure a sufficient dissociation of hardly soluble weak acids in the solution, the amount of wood suspended in Na2HPO4 solutions should be small but vary depending on the degree of acidity of wood species. However, the difficulties are associated with the titration of very dilute acids limiting the precision of the measurement. If the disintegrated wood is suspended in a secondary phosphate solution, the weak woods acids form the conjugate acid Na2HPO4 from secondary phosphate Na2HPO4 resulting in a pH fall of the solution. The decrease in the pH value in phosphate solution, which depends on the wood acidity, can be evaluated to estimate the acidity arising from wood under moderate conditions
AquaÂ(di-2-pyridylÂamine-Îș2 N 2,N 2âČ)(pyridine-2,6-dicarboxylÂato-Îș3 O 2,N,O 6)zinc monohydrate
In the title compound, [Zn(C7H3NO4)(C10H9N3)(H2O)]·H2O, the ZnII atom has a distorted octaÂhedral coordination geometry. One of the water molÂecules is coordinated with the ZnII ion and this molÂecule forms an OâHâŻO interÂaction with the lattice water molÂecule. The pyridine-2,6-dicarboxylÂate ligand is almost planar (r.m.s. deviation = 0.0242â
Ă
). In the crystal, CâHâŻO, CâHâŻN, OâHâŻO and NâHâŻO hydrogen bonds are present
Essential wood oil of Cupressus sempervirens varieties (horizontalis and pyramidalis)
WOS: 000475471200003The essential oils isolated from the woods of Cupressus sempervirens var. horizantalis and var. pyramidalis harvested from natural and cultivated locations in Turkey were characterized by GC-MS analyses. Fifty-one compounds, representing 91.9-95.7% of the oil composition, were identified. The oils obtained from two varieties wood exhibited quite similar composition. Sapwood and heartwood oils were mainly composed of oxygenated monoterpenes (43.7-72.4%), sesquiterpenoids (8.7-36.5%) and diterpenoids (2.2-10.4%). The major compounds were carvacrol methyl ether (38.2-62.6%), alpha-cedrol(15.7-34.3%), manool (1.75-9.83%), terpinen-4-ol acetate (0.82-4.15%) and bornylacetate (0.26-4.62%). Compared to other Cupressus species, Cupressus sempervirens wood can be classified as a carvacrol methyl ether rich species. As a result, the wood oil of Cupressus species can be characterized by the presence of two compounds: a-cedrol and carvacrol or carvacrol methyl ether

Effects of the combined treatment of bilateral subthalamic nucleus stimulation and levodopa on balance and mobility in Parkinsonâs disease = A kombinĂĄlt kĂ©toldali subthalamicusmag-stimulĂĄciĂł Ă©s levodopakezelĂ©s hatĂĄsa az egyensĂșlyra Ă©s a mobilitĂĄsra Parkinson-kĂłrban
Background and purpose â To evaluate
the efficacy of the combined therapy of bilat-
eral subthalamic nucleus deep brain stimula-
tion (STN-DBS) and dopaminergic medication
on balance and mobility in patients with
Parkinsonâs disease (PD).
Methods â Eighteen PD patients under
bilateral STN-DBS stimulation therapy, were
enrolled in this study. Unified Parkinsonâs
Disease Rating Scale (UPDRS) was applied
to assess the patientsâ clinical character-
istics. UPDRS part III postural instability/
gait disorder (PIGD) scores (sum of items
3.9-3.13) and UPDRS part III postural stability
item (item 3.12) were calculated separately.
Patients were evaluated with Berg Balance
Scale (BBS), Mini-Balance Evaluation Systems
Test (Mini-BESTest), Timed Up and Go (TUG)
test, dual-task TUG test, and Forward Func-
tional Reach (FFR) Test in two conditions:
Stimulation-ON (stim-ON)/Medication-ON
(Med-ON) and Stimulation-OFF (Stim-OFF)/
Med-ON
Results â The mean age of patients was
59.5±9.1 (R: 41-71) years. The UPDRS part
III total score and PIGD subsection score
significantly improved after stimulation
(p=0.001), but the postural instability item of
the UPDRS part III did not change signifi-
cantly (p=0.1). There were no significant
differences between the Stim-ON/Med-ON
and Stim-OFF/Med-ON conditions, in terms
of total Mini-BESTest total scores, total BBS
score, FFR test score (p>0.05 for all of them). TUG test was significantly improved in the
Stim-ON/Med-ON condition compared to
Stim-OFF/Med-ON condition (p=0.03), but
DT-TUG test did not change (p=0.1).
Conclusion â Combined bilateral STN-DBS
and dopaminergic medication therapy had
an additional improvement on motor symp-
toms and mobility performance, but not on
balance and dual-task mobility. | HĂĄttĂ©r Ă©s cĂ©l â A kĂ©toldali subthalamicus
