Bioturbation effects on bioaccumulation of cadmium in the wetland plant Typha latifolia: A nature-based experiment.

The development of efficient bioremediation techniques to reduce aquatic pollutant load in natural sediment is one of the current challenges in ecological engineering. A nature-based solution for metal bioremediation is proposed through a combination of bioturbation and phytoremediation processes in experimental indoor microcosms. The invertebrates Tubifex tubifex (Oligochaeta Tubificidae) was used as an active ecological engineer for bioturbation enhancement.

Powder crystallography of pharmaceutical materials by combined crystal structure prediction and solid-state 1H NMR spectroscopy.

A protocol for the ab initio crystal structure determination of powdered solids at natural isotopic abundance by combining solid-state NMR spectroscopy, crystal structure prediction, and DFT chemical shift calculations was evaluated to determine the crystal structures of four small drug molecules: cocaine, flutamide, flufenamic acid, and theophylline. For cocaine, flutamide and flufenamic acid, we find that the assigned (1)H isotropic chemical shifts provide sufficient discrimination to determine the correct structures from a set of predicted structures using the root-mean-square deviation (rmsd) between experimentally determined and calculated chemical shifts. In most cases unassigned shifts could not be used to determine the structures.

Changes in endometrial thickness, width, length and pattern in predicting pregnancy outcome during ovarian stimulation in in vitro fertilization.

Objective: To determine whether the clinical features of the endometrium as observed by transvaginal high resolution sonography are predictive of pregnancy outcome in in vitro fertilization cycles.

Patients And Methods: One hundred and forty-five patients undergoing in vitro fertilization were included in this prospective controlled study. Endometrial thickness, width, length, growth and pattern during the follicular and early luteal phases of stimulated cycles were assessed using transvaginal ultrasound by an operator who was blinded to the protocol of stimulation and to the type of assisted reproductive technology treatment.

Ovarian stimulation during assisted reproduction treatment: a comparison of recombinant and highly purified urinary human FSH. On behalf of The Feronia and Apis study group.

This randomized, single-blind, multicentre, multinational study compared recombinant human FSH (rhFSH, Gonal-F) with highly purified urinary human FSH (uhFSH, Metrodin HP) in women undergoing ovarian stimulation for IVF/intracytoplasmic sperm injection (ICSI). Following desensitization in a long gonadotrophin-releasing hormone (GnRH) agonist protocol, patients received s.c.

A randomized prospective cross-over study of highly purified follicle-stimulating hormone and human menopausal gonadotrophin for ovarian hyperstimulation in women aged 37-41 years.

Purpose: In the present study, we investigated the benefits of highly purified FSH (H.P. FSH) in comparison with human menopausal gonadotrophin (hMG) in IVF patients aged 37-41 years.

In vitro fertilization outcome according to age and follicle-stimulating hormone levels on cycle day 3.

Purpose: In a retrospective study, the prognostic factors of in vitro fertilization outcome were studied in women of 39 years of age or older, with an elevated cycle day 3 follicle-stimulating hormone (FSH) level.

Methods: Ovarian stimulation was achieved with a combination of gonadotropin-releasing hormone agonist/human menopausal gonadotropin in a short protocol. All patients underwent FSH dosage on cycle day 3 prior to stimulation.

Outcome of in-vitro fertilization through natural cycles in poor responders.

This prospective study examines the benefits of using natural cycles instead of stimulated cycles in poor responders to in-vitro fertilization (IVF) treatment. Eleven patients in whom puncture was cancelled or who failed to conceive because of a poor response were included in the analysis. The data for natural cycles (n = 16) were compared with data obtained during previous stimulated cycles (n = 25) in the same women.

Successful laparoscopic management of adnexal torsion during week 25 of a twin pregnancy.

Adnexal torsion is a rare occurrence during pregnancy. Here we present a case of adnexal torsion during the 25th week of pregnancy, which was managed laparoscopically. The woman had achieved a successful twin pregnancy after in-vitro fertilization/intracytoplasmic sperm injection.

Indications for cryopreservation of ovarian tissue.

For patients who are planning to have chemotherapy, radiotherapy or to undergo bilateral oophorectomy, loss of ovarian function will result in premature ovarian menopause and loss of fertility. For these women, although there is no successful method for the cryopreservation of human oocytes, ovarian tissue cryobanking is proposed with a view to its autotransplantation at a later date or the isolation and in-vitro maturation of oocytes. Embryo preservation is indeed not an option for single women and even for married women because delaying treatment for at least 2 months of in-vitro fertilization cycles is inappropriate and life-threatening.

Predictive factors for multiple pregnancy in in vitro fertilization.

Objective: To study predictive factors influencing the multiple pregnancy rate in in vitro fertilization (IVF).

Expansive benign lesions: treatment by laser.

Submucous fibroids, polyps and dysfunctional bleeding are responsible for meno-metrorrhagia in women over 40 years of age. The authors describe the technique of hysteroscopic myomectomy and endometrial ablation using the Nd-YAG laser and the advantages of the preoperative use of GnRH agonist therapy. They report their results in a series of 746 patients treated for meno-metrorrhagia (366 cases of myomectomy and 380 cases of endometrial ablation).

Large ovarian endometriomas.

The management of large endometriomas was described in a series of 814 patients. Combined therapy using gonadotrophin-releasing hormone agonist (GnRHa) and carbon dioxide laser laparoscopy was proposed. Drainage and GnRHa for 12 weeks provoked a reduction of the endometrioma size up to 50% of the initial value.

Morphometric, immunohistological and three-dimensional evaluation of the endometrium of menopausal women treated by oestrogen and Crinone, a new slow-release vaginal progesterone.

Recently advanced computerized technology was applied to the investigation of morphometric, immunohistological and three-dimensional changes of the endometrial mucosa in order to evaluate quantitatively the effects of three doses of a new slow-release vaginal progesterone on the endometrium in post-menopausal women. A total of 20 menopausal women, deprived of ovarian function, were given oestrogen for 12 days and a combined therapy of oestrogen (administered orally) and progesterone for another 12 day period. Progesterone was administered vaginally through a new gel (Crinone) utilizing a bioadhesive, biocompatible polymer as a base to achieve a sustained release effect.
