We investigated the germination requirements of Androsace villosa L. (Hairy Androsace), which spreads on limestone or granite screes or ledges of rocky or turfy slopes and hilltops of the alpine zone. With seeds collected from Uludag Mt. (Bursa, Turkey, 2200–2300 m a.s.l.), germination was studied in fresh seeds, seeds subjected to short-time moist chilling (15 d, +4°C), to GA3 (100, 150 and 250 ppm), and to chilling plus GA3. The hormone and moist chilling treatments were carried out in continuous darkness (20°C) and under a 12 h photoperiod at 20/10°C. Seeds maintained in darkness gave higher germination percentages than seeds maintained under a photoperiod. Germination rates rose to 90–97% with 100–250 ppm GA3 and short-time moist chilling in continuous darkness (20°C). Seeds germinated rapidly under a combination of GA3 and short-time moist chilling in continuous darkness, generally giving the lowest mean germination times (4.4–5.0 d) among the treatments.

N,N-dimethyl-N'-(2-chloro-benzoyl)thiourea (L1H) and N-pyrrolidine-N'-(2-chlorobenzoyl) thiourea (L2H) and their Ni(II), Cu(II), Zn(II), Pt(II), Pd(II) and Co(III) complexes. The structure of the prepared compounds was investigated by using elemental analyses, IR, 1H-NMR, UV-Vis, mass spectra and magnetic susceptibility. The prepared compounds were screened for their in vitro antibacterial and antifungal activities. All compounds showed antimicrobial activity, however, the antibacterial efficacy is better than antifungal activity. Molecular structures of Co(L1)3 and Pd(L1)2 were determined by single crystal X-ray diffraction methods. The ligands coordinate to Ni(II), Cu(II), Zn(II), Pt(II) and Pd(II) in a bidentate manner yielding essentially neutral complexes of the type ML2. The coordination polyhedra around the Co(III) ion are distorted octahedra.

Background: There is an increasing trend for administration of invasive radiological interventions, laparoscopic surgery, and transplantation procedures in recent years, and determining the vascular variations prior to these procedures is crucially important. Coeliacomesenteric trunk (CMT) is among these variations. This study aimed to retrospectively evaluate this rare anomaly by computed tomography (CT). Materials and methods: A total of 1000 CT angiography images were analysed retrospectively, and the patients with mesenteric and coeliac arteries arising from the abdominal aorta with a single root were identified. The level that CMT arose, and its branching patterns were determined individually for all patients. Results: Ten patients (6 males and 4 females) with a mean age of 50.2 years (17–87 years) had CMT in CT images. Conclusions: The knowledge of variations in the CMT prior to vascular or laparoscopic interventions will contribute to early intervention in case of a complication, or to avoid from a potential damage.
