Objective(s):Glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. Glutathione S-transferases (GSTs) are members of multigenic family, which have important role in cells as an antioxidant. In the present study, we examined the polymorphism of GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0, and T0M0) in 100 Glaucoma patients (41with pr...

The feeding kinematics of dwarf and pygmy sperm whales (Kogia sima and K. breviceps) and bottlenose dolphins Tursiops truncatus were characterized and compared incorporating the Ram-Suction Index (RSI). Mean RSI data support a suction feeding strategy for Kogia (-0.67+/-0.29; mean +/- s.d.) and a ram feeding strategy for Tursiops (0.94+/-0.11; mean +/- s.d.). Tursiops displayed two ram-based fe...

The title compound, [Fe(2)(C(14)H(10)NS(2))(2)(CO)(6)], was synthesized as a structural and biochemical model for the active site of [FeFe]-hydrogenase. The bond lengths (Fe-Fe, Fe-S and Fe-C) and angles (C-Fe-Fe and Fe-S-Fe) are within expected ranges. The S⋯S distance [2.9069 (12) Å] and the dihedral angle between two Fe-S-Fe planes [78.5 (3)°] of the butterfly-shaped Fe(2)S(2) core are enlar...

The title thia-calix[4]arene derivative, C(36)H(34)Br(2)O(8)S(4), adopts an unusual pinched cone conformation with the prop-oxy-substituted benzene rings inclined inward [forming a dihedral angle of 33.4 (1)°] and with the brominated benzene rings bent outward, making a dihedral angle of 66.1 (1)°. In the crystal, the mol-ecules form chains along [001] via C-H⋯S hydrogen bonds and S⋯S contacts ...

In the title molecular salt, 2C(6)H(14)N(+)·C(14)H(8)O(4)S(2) (2-), the complete dianion is generated by crystallographic twofold symmetry and a twisted conformation is found [the C-S-S-C torsion angle is 87.13 (2)° and the dihedral angle between the rings is 83.4 (2)°]. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the cations and anions.

The association between the Angle classification and craniofacial form has been analysed with the aid of multiple linear regression analysis in a sample of 170 children, before orthodontic treatment had started. It was found that part of the differences between Class II, Class I, and Class III was accounted for by systematical variation in a coherent set of midface and cranial base dimensions. ...

The title compound, C18H28N2S2·CHCl3, crystallizes as a zwitterion. The C-S bonds are almost equivalent, with lengths of 1.666 (3) and 1.657 (3) Å. The S-C-S bond angle is expanded to 129.54 (16)° and the N-C-N angle is reduced to the tetra-hedal value of 108.8 (2)°. In the crystal, adjacent mol-ecules are linked via C-H⋯S hydrogen bonds, forming chains along [100]. The chloro-form solvent mol-...

In the title mol-ecule, C(15)H(17)NO(3)S, the C-S-N-C(benzene) torsion angle is 81.45 (16)°, and the two aromatic rings form a dihedral angle of 45.83 (12)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the b axis.

in this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (qesc) have been simulated and investigated. optical path technic is used for simulation. the results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the qesc. simulation r...

In the title compound, C(15)H(12)S(4), two phenyl-dithio-carboxyl-ate units are linked through a methyl-ene C atom on a twofold rotation axis. The central S-CH(2)-S angle of 116.9 (5)° is significantly larger than the ideal tetra-hedral value. The dihedral angle formed by the two phenyl rings is 68.2 (1)°. The refined Flack parameter of 0.2 (3) does not permit unambiguous determination of the a...
