The crystal structures of chloro(
meso-tetraphenylporphyrinato)germanium(IV), Ge(tpp)Cl
2, dimethoxo(
meso-tetraphenylporphyrinato)germanium(IV), Ge(tpp)(OMe)
2, and dihydroxo(
...meso-tetraphenylporphyrinato)germanium(IV), Ge(tpp)(OH)
2, were determined. The coordination sphere of the Ge
4+ ion is a distorted octahedron in which the apical sites are occupied by two monodentate Cl
− (or OMe
−, OH
−) groups. The geometry around the germanium centre of the Ge(tpp)Cl
2 molecule has Ge(1)Cl(1) = 2.262(1) and Ge(1)N(1) = 2.019(2) Å. In the structure of Ge(tpp)(OMe)
2 the germanium(1)-oxygen distance is 1.826(3), average Ge(1)N = 2.032(3), and O(1)C(23) = 1.331(6) Å. The structure of Ge(tpp)(OH)
2 has Ge(1)O(1) = 1.809(3) and Ge(1)N(1) = 2.027(2) Å. Two-stage hydrolysis of Ge(tpp)(OMe)
2 was studied by
1H and
13C NMR spectroscopy. The use of a limited amount of water in CDCl
3 (or CD
2Cl
2) allowed the hydrolysis intermediate, hydroxomethoxo(
meso-tetraphenylporphyrinato)germanium(IV), Ge(tpp)(OMe) (OH), and hydrolysis product, dihydroxo(
meso-tetraphenylporphyrinato)germanium(IV), Ge(tpp)(OH)
2, to be identified. X-ray diffraction data and solid-state
13C CP/MAS spectra of Ge(tpp)(OMe)
2 provide evidence for two monodentate methoxo groups coordinated to the germanium(IV) atom.
Bowel injury is a rare but potentially fatal complication of laparoscopy if it is unrecognized at the time of the procedure. Once a bowel injury is identified, it must be repaired by either ...laparoscopy or laparotomy. The Endo GIA 30 stapler is effective for achieving large-vessel hemostasis and facilitating laparoscopic procedures, and is reported safe for laparoscopic hysterectomy. It was used successfully in two women to repair extensive bowel injuries.
Introduction: In previous study, a capsinoids intake would enhance the energy expenditure and fat oxidation in humans. If a capsinoids (CSN) can stimulate fat oxidation and spare glycogen stores ...following exercise resulting in delaying exercise-induced fatigue. The purpose of the study was to investigate the effect of acute oral CNS supplementation on fat oxidation, muscle glycogen and fatigue during exercise. Methods: Ten healthy subjects (age 20.6 ± 0.3 years; height 171.3 ± 2.4 cm; weight 67.0 ± 3.4 kg; BMI 21.1 ± 0.6 kg/m2; V ‧ O2 max 46.4 ± 2.4 ml/kg/min) completed a crossover study design with CNS and placebo trials and performed a single bout of cycling exercise challenge with glycogen depletion protocol for 70 minutes, separated a 7-d washout period. All subjects consumed 30 mg CSN or placebo with light breakfast before exercise challenge. Blood samples were measured before meal and during exercise. Expired gas samples were collected during exercise. Simultaneously, muscle biopsy samples were obtained
