The prognosis of IPMN is better than that of pancreatic cancer. However the risk of recurrence in invasive IPMC was found to be 7-21%. Therefore, IPMC must be surveilled every three months using tumor markers and imaging. Local recurrence in remnant pancreas is usually treated with systemic therapy. The median long-term survival after total pancreatectomy (range 7-24 months) was shown to be better than when chemotherapy alone was used (range 10-13 months).

We chose secondary surgery in term of survival time although there are quality of life drawbacks that currently make total pancreatectomy more inappropriate in patients than chemotherapy.

Dural tear and cerebrospinal fluid (CSF) leak is among the most common complications in lumbar spine surgery. Although primary dural suturing is the preferred method for repair, this is not always achievable specially with ventrolateral tears. Autologous fat grafting is one of the oldest and effective methods for dural repair which can also be used along with other methods of repair. This case report highlights a unique post spinal surgery complication with comment on how to avoid it. To our knowledge, this has not been previously reported in the literature.

The authors report a sixty-seven-year-old male with lumbar pseudomeningocele and cranial fat dissemination following fat grafting for non suturable lumbar dural tear. This was demonstrated on magnetic resonance imaging (MRI) after her presented with low-pressure headache.

Intraoperative dural tear is one of the most common complications in spinal surgery. Methods for optimal dural repair including fat grafting have been described but the choice still heavily dependent on the surgeon's preference and experience. Fat graft can migrate leading to potential undesirable further complications like hydrocephalus and aseptic meningitis.

Cranial fat dissemination following fat grafting for lumbar dural tear should be recognized as a post-operative complication in lumbar spine surgery. It should be considered in case of hydrocephalus or aseptic meningitis post dural fat grafting. Surgeons should utilize adjunct methods to minimize its incidence.

The SL pathway has been shown to be affected in several brain-related disorders, including Alzheimer's disease (AD). Recent evidence suggests that epigenetic dysregulation plays an important role in the pathogenesis of AD as well. Here, we use an integrative approach to better understand the relationship between epigenetic and transcriptomic processes in regulating SL function in the middle temporal gyrus of AD patients. Transcriptomic analysis of 252 SL-related genes, selected based on GO term annotations, from 46 AD patients and 32 healthy age-matched controls, revealed 103 differentially expressed SL-related genes in AD patients. Additionally, methylomic analysis of the same subjects revealed parallel hydroxymethylation changes in PTGIS, GBA, and ITGB2 in AD. Subsequent gene regulatory network-based analysis identified 3 candidate genes, that is, SELPLG, SPHK1 and CAV1 whose alteration holds the potential to revert the gene expression program from a diseased towards a healthy state. Together, this epigenomic and transcriptomic approach highlights the importance of SL-related genes in AD, and may provide novel biomarkers and therapeutic alternatives to traditionally investigated biological pathways in AD.Carbon black and fuel oil as the products of conventional pyrolysis are limited in application owing to their low quality. This paper presents a pyrolysis-based high-value utilization process of waste passenger tires (WPTs). A comparison of the life cycle assessment (LCA) between this process and a conventional pyrolysis process was carried out. this website Moreover, a comprehensive evaluation index of the ratio of economic profit to environmental cost (PCR) was established. The results show that the increase in economic profits brought about by the high-value utilization process is higher than the increase in environmental costs, and the pyrolysis-based high-value utilization of WPTs has more positive benefits than conventional pyrolysis. Reducing the consumption of electricity and natural gas in the high-value utilization process has a significant effect on the decline of the main environmental impacts. Compared with the production of conventional pyrolytic products, this has the dual advantages of resource saving and environmental protection. Also, the environmental loads of ozone layer depletion (ODP) and human toxicity (HTP) are reduced by over 90%, and the loads of abiotic depletion (ADP) of minerals and fossil fuels are reduced by over 84%. Sensitivity analyses show that both the production cost and the price of carbon black significantly influence the PCR. The replacement of coal-fired power generation with renewable energy generation has a positive effect on improving the resource and environmental performance for the high-value utilization process of WPTs.In 2018 and 2019 the City of Boston (Massachusetts, USA) conducted zero waste and carbon neutral planning efforts. Here we present the results of an accompanying analysis of the impacts of zero waste strategies on greenhouse gases (GHG) emissions associated with waste treatment. Emissions analysis in the waste sector is complicated by the contribution of significant indirect impacts that can exhibit temporal and spatial heterogeneity. For example, lifecycle GHG analysis of waste-to-energy combustion grants credits for the emissions avoided due to electricity generated from organic waste (biogenic carbon) that displaces electricity generation that could be carbon-emitting. As electricity grids decarbonize, this credit approaches zero. Long-term emissions planning needs to account for such dynamics to realistically assess the GHG mitigation potential associated with alternative waste management strategies. Here, we seek to capture these dynamics in a forward-looking analysis of waste sector emissions under a zero-waste strategy for the City of Boston.
