“A 29-year-old woman was diagnosed with a cervico-isthmic pregnancy based on ultrasound findings at 8 weeks of gestation. At 30 weeks of gestation, placenta previa was confirmed. During cesarean section at 37 weeks, the placenta did not spontaneously detach from the uterus; therefore, we decided to leave it in the uterus to avoid major hemorrhage. Blood loss was 775 mL and a healthy infant was delivered. After the

operation, weekly methotrexate injection was initiated. Shortly after the eighth course of injection, massive Anlotinib vaginal bleeding suddenly occurred and bilateral uterine artery embolization was performed to control it. After the procedure, the retained placental tissue was removed and the patient was discharged with good general condition. Although a cervico-isthmic pregnancy constitutes a high-risk pregnancy,

fertility-sparing management without a hysterectomy or blood transfusion was possible by not removing the placenta manually during the operation.”
“BACKGROUND: Scrubbing using an organic solution instead of an aqueous solution could be a useful way to improve the removal of hydrophobic compounds. Absorption of toluene, dimethyldisulfide (DMDS) and dimethylsulfide (DMS) in an organic solution (di-2-ethylhexyladipate – DEHA), followed by biodegradation by activated Z-DEVD-FMK Apoptosis inhibitor sludge was considered, with particular attention find more to kinetic aspects. DEHA was selected for its relevance in terms of absorption capacity and absorption velocity of the selected volatile organic compounds (VOCs). After

the biodegradation step and owing to its cost, recycling of the VOC-free solvent should be considered.

RESULTS: Enhancement of VOC mass transfer from the organic to the aqueous phase due to bacterial activity was highlighted and the main driving force was found to be biosurfactant production rather than biodegradation reaction. However, the mass transfer rate between the two phases was shown to be lower than VOC biodegradation rate; hence, significant biodegradation of DMDS and toluene was recorded in a few days during batch experiments, 0.10 and 0.09 mmol respectively. Toluene showed higher biodegradation rates (about 0.05 and 0.10 mg h(-1) for DMDS and toluene), leading to higher growth rates. Contrarily, owing to its high volatility, important DMS losses were observed.

CONCLUSION: The relevance of the proposed integrated process was shown for hydrophobic VOC removal, at least for toluene and DMDS. Unfortunately, the absorbent phase was also degraded, proved by detection of by-products during analyses of the aqueous phase headspace.
