Unveiling spatial variations in atmospheric CO sources: a case study of metropolitan area of Naples, Italy.

In the lower atmosphere, CO emissions impact human health and ecosystems, making data at this level essential for addressing carbon-cycle and public-health questions. The atmospheric concentration of CO is crucial in urban areas due to its connection with air quality, pollution, and climate change, becoming a pivotal parameter for environmental management and public safety. In volcanic zones, geogenic CO profoundly affects the environment, although hydrocarbon combustion is the primary driver of increased atmospheric CO and global warming.

High-resolution geoelectrical characterization and monitoring of natural fluids emission systems to understand possible gas leakages from geological carbon storage reservoirs.

Gas leakage from deep geologic storage formations to the Earth's surface is one of the main hazards in geological carbon sequestration and storage. Permeable sediment covers together with natural pathways, such as faults and/or fracture systems, are the main factors controlling surface leakages. Therefore, the characterization of natural systems, where large amounts of natural gases are released, can be helpful for understanding the effects of potential gas leaks from carbon dioxide storage systems.

Modified natural cycle in vitro fertilization an alternative in vitro fertilization treatment with lower costs per achieved pregnancy but longer treatment time.

Objective: To analyze the cost and time requirement per achieved pregnancy in optimized modified natural cycle in vitro fertilization (mNC-IVF) based on a treatment protocol with very few consultations and to compare those with conventional gonadotropin-stimulated aVF (clVF) cycles.

Study Design: Mono centric prospective trial. Eighty infertile patients each received 1 modified mNC-IVF cycle using low doses of the clomiphene citrate.

Follicle flushing in monofollicular in vitro fertilization almost doubles the number of transferable embryos.

Follicle flushing has been proved to be ineffective in polyfollicular in vitro fertilization. To analyze the effect of flushing in monofollicular in vitro fertilization we aspirated and then flushed the follicles in 164 cycles. Total oocyte yield/aspiration was 44.

Increased endometrial placenta growth factor (PLGF) gene expression in women with successful implantation.

Objective: To analyze the vascularization of the endometrium via hysteroscopy and to assess its correlation with angiogenic factor gene expression and embryo implantation rate.

Design: Cross-sectional study.

Setting: Public university hospital.

Vaginal prolapse, pelvic floor function, and related symptoms 16 years after sex reassignment surgery in transsexuals.

Objective: To evaluate the prevalence of prolapse and related bladder, bowel, and sexual problems in transsexual patients (TS) after sex reassignment surgery.

Design: A cross-sectional study.

Setting: A tertiary referral center.

Combination of gonadotropin-releasing hormone (GnRH) agonists with GnRH antagonists before chemotherapy reduce but does not completely prevent a follicle-stimulating hormone flare-up.

Increasing evidence supports GnRH agonists to be an effective treatment to preserve ovarian function during chemotherapy, but the initial flare-up of FSH during the first week after GnRH agonist application still limits its use. The combination of GnRH agonists with GnRH antagonists might solve this problem to some extent as the addition of GnRH antagonists at least significantly reduces the FSH flare-up.

Peroxisome proliferator-activated receptor-(gamma) receptor ligand partially prevents the development of endometrial explants in baboons: a prospective, randomized, placebo-controlled study.

A prospective, randomized, placebo-controlled study was conducted in a baboon model to determine if a thiazolidinedione agonist of peroxisome proliferator-activated receptor-gamma, pioglitazone, can impede the development of endometriosis. Endometriosis was induced using laparoscopic, intrapelvic injection of eutopic menstrual endometrium, previously incubated with placebo or pioglitazone for 30 min, in 12 female baboons with a normal pelvis that had undergone at least one menstrual cycle since the time of captivity. At this point, the 12 baboons were randomized into two groups and treated from the day of induction.

Iatrogenic orifice transluminal endoscopic surgery (IOTES): managing uterine perforations at operative hysteroscopy.

Objective: To prove safety and feasibility of an intra-abdominal endoscopic evaluation via an iatrogenic uterine perforation that occurred during operative hysteroscopy.

Design: Clinical case report.

Setting: University Hospital.

Laparoscopy or laparotomy? A comparison of 240 patients with early-stage endometrial cancer.

Background: This study aimed to compare the safety and efficacy of laparoscopy and laparotomy in the surgical treatment of early endometrial cancer, especially in obese women.

Methods: The results obtained after laparoscopic surgical treatment of early endometrial cancer (International Federation of Gynecology and Obstetrics (FIGO) stage 1 or 2) in patients between 1996 and 2007 were compared with an age- and tumour-matched historical group of patients treated with laparotomy between 1988 and 1996. All the patients underwent hysterectomy, bilateral salpingo-oophorectomy, and pelvic + or - paraaortic lymphadenectomy.

Severe traumatic brain injury in children--are the results improving?

Questions Under Study: Traumatic brain injury (TBI) remains an important cause of mortality and morbidity in children. Medical management is constantly being refined, and thus results should improve. The aim of the present study was to analyse our data of recent years and to compare them with previous series (1978-83 and 1988-92).
