Membrane technology is becoming more important for CO,_ separation from natural gas in the new era due to its process simplicity, relative ease of operation and control, compact, and easy to scale up as compared with conventional processes. Conventional processes such as absorption and adsorption for CO2 separation from natural gas are generally more energy demanding and costly for both operation and maintenance. Polymeric membranes are the current commercial membranes used for CO2 separation from natural gas. However, polymeric membranes possess drawbacks such as low permeability and selectivity, plasticization at high temperatures, as well as insufficient thermal and chemical stability. The shortcomings of commercial polymeric membranes have motivated researchers to opt for other alternatives, especially inorganic membranes due to their higher thermal stability, good chemical resistance to solvents, high mechanical strength and long lifetime. Surface modifications can be utilized in inorganic membranes to further enhance the selectivity, permeability or catalytic activities of the membrane. This paper is to provide a comprehensive review on gas separation, comparing membrane technology with other conventional methods of recovering CO2 from natural gas, challenges of current commercial polymeric membranes and inorganic membranes for CO2 removal and membrane surface modification for improved selectivity.

Background Intraoperative ultrasound （IOUS） has been procedures. In this study, we aimed to evaluate the potential the resection of small, deep-seated, or ill-defined lesions. ncreasingly used as a guiding tool during neurosurgical application of intraoperative ultrasound assisted surgery in Methods Eighty-six consecutive patients with small, deep-seated, or ill-defined intracerebral lesions were studied prospectively. An improved intraoperative imaging technique and surgical setup were practiced during the surgery. IOUS was performed in three orthogonal imaging planes （horizontal, coronal and sagittal）. Results Histopathological diagnoses of these 86 cases included cavernomas, metastases, hemangioblastomas, gliomas, and radiation necrosis. Forty-seven of the 86 lesions （54.7%） were small and deep-seated, 34/86 （39.5%） were ill-defined, and 5/86 （5.8%） were small, deep-seated, and ill-defined. Sonograms in the horizontal plane were obtained in all 86 cases. Sonograms in the sagittal plane and in the coronal plane were obtained only in 52 cases and in 46 cases, respectively, due to technical limitation. In 13 cases, sonograms in all three orthogonal planes were available. All lesions were successfully identified and localized by IOUS. Total resection was performed in 67 lesions （77.9%） and partial resection was performed in 19 lesions （22.1%）. Conclusions We propose IOUS to be performed in three orthogonal planes when surgery is planned for small, deep-seated, or ill-defined brain lesions. By applying this simple, improved technique, surgeons can perform resection of these lesions precisely.

AIM: To investigate the age differences in the risk factors, clinicopathological characteristics and patterns of treatment of female breast cancer patients. METHODS: Seven thousand one hundred and fiftytwo women with primary breast cancer from the Hong Kong Breast Cancer Registry were recruited after receiving patients' consent, they were asked to complete standardized questionnaires which captured their sociodemographic characteristics and risk factors associated with breast cancer development. Among them, clinicopathological data and patterns of treatment were further collected from medical records of 5523 patients with invasive breast cancers. Patients were divided into two groups according to the age at diagnosis: younger(< 40 years old) vs older patients(≥ 40 years old) for subsequent ***: Analysis on the sociodemographic characteristics and exposure to risk factors were performed on 7152 women with primary breast cancer and the results revealed that younger patients were more likely to have unhealthy lifestyles; these include a lack of exercise(85.4% vs 73.2%, P < 0.001), having high stress in life(46.1% vs 35.5%, P < 0.001), having dairy/meat-rich diets(20.2% vs 12.9%, P < 0.001),having alcohol drinking habit(7.7% vs 5.2%, P = 0.002). Younger patients were also more likely to have hormone-related risk factors including nulliparity(43.3% vs 17.8%, P < 0.001) and an early age at menarche(20.7% vs 13.2%, P < 0.001). Analyses on clinicopathological characteristics and patterns of treatment were performed on 5523 women diagnosed with invasive breast cancer. The invasive tumours in younger patients showed more aggressive pathological features such as having a higher percentage of grade 3 histology(45.7% vs 36.5%, P < 0.001), having a higher proportion of tumours with lymphovascular invasion(39.6% vs 33.2%, P = 0.003), and having multifocal disease(15.7% vs 10.3%, P < 0.001); they received different patterns of treatment than their older ***
