N-hexane neuropathy is an occupational disease caused by exposure to n-hexane, which is used as a solvent in silk screen printing. Here, we describe a 35-year-old man, a silk screen printer by profession, who presented with dizziness, distal swelling of both lower limbs for 10 months and tingling and burning sensation in both feet for 9.5 months along with cold allodynia. The patient had normal...

BACKGROUND Within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of Annona senegalensis leaf extract and its 4 fractions against Anopheles gambiae and Culex quinquefasciatus were evaluated in the laboratory conditions. METHODS Ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while la...

Dates fruit has been used as staple food in the Middle East for thousands of years and various types of dates are found worldwide. Dates and their constituents show various roles in diseases prevention and treatment through anti-oxidant, anti-inflammatory, anti-bacterial activity. In the present study we investigated the activity of aqueous and n-hexane extracts of Phoenix dactylifera L. fruit ...

Reaction of the deprotonated N-thiophosphorylated thiourea (4'-benzo-15-crown-5)NHC(S)NHP(S)(OiPr)(2) (HL) with NiCl(2) in aqueous EtOH leads to dark green [Ni(L-1,5-S,S')(2)]·2H(2)O crystals that were isolated by recrystallization from a mixture of CH(2)Cl(2) and n-hexane.

In the title compound, C(21)H(21)N(3)OS·C(3)H(7)NO, the carbonitrile mol-ecule is built up of two fused six-membered rings and one six-membered ring linked through a spiro C atom. The 1,3-diaza ring adopts an envelope conformation and the cyclo-hexane ring adopts a chair conformation. The dihedral angle between the aromatic rings is 46.7 (3)°. In the crystal, the components are linked by N-H⋯O ...

In the title compound, C(23)H(26)FN(3)O(6)S, the two terminal aromatic rings form a dihedral angle of 49.26 (12)°. The cyclo-hexane ring adopts a chair conformation and the five-membered ring is essentially planar, with a maximum deviation from planarity of 0.0456 (19) Å. The dihedral angles between the five-membered ring and the meth-oxy-benzene and fluoro-benzene rings are 33.56 (11) and 81.9...

In the title compound, C(13)H(16)FNO, the fluoro-benzene ring plane and the plane through the amide unit are inclined at a dihedral angle of 29.92 (7)°. The cyclo-hexane ring adopts a chair conformation. In the crystal structure, N-H⋯O hydrogen bonds, augmented by weak C-H⋯O inter-actions, link the mol-ecules into transverse chains along a. These chains are linked into zigzag columns down a by ...

In the title compound, 2C6H11N2 (+)·P2Se8 (2-) or [EMIM]2P2Se8 (EMIM = 1-ethyl-3-methyl-imidazolium), the anions, located about inversion centers between EMIM cations, exhibit a cyclo-hexane-like chair conformation. The cations are found in columns along the a axis, with centroid-centroid distances of 3.8399 (3) and 4.7530 (2) Å. The observed P-Se distances and Se-P-Se angles agree with other s...

The title compound, C(15)H(13)F(3)N(2)O, contains one benzene ring, one cyclo-hexane ring and a pyridazine ring. The dihedral angle formed by the pyridazine ring with the benzene ring is 61.5 (2)°. The crystal structure is stabilized by two inter-molecular hydrogen bonds (N-H⋯O and C-H⋯F). The cyclohexane ring adopts a screw-boat conformation. The CF(3) group is disordered over two positions; t...

The title compound, C(14)H(18)N(2)O, was synthesized by the reaction of cyclo-hexa-none and 2-amino-5-methyl-benzonitrile. In the mol-ecule, the cyclo-hexane ring displays a chair conformation, whereas the 1,3-diaza-cyclo-hexane moiety of the bicyclic system has a sofa conformation with the spiro C atom displaced by 0.603 (2) Å from the rest of the atoms of the 1,3-diaza-cyclo-hexane ring [plan...
