9. México—Addressing Challenges to Reforestation

Author

Burney, Owen, Aldrete, Arnulfo, Alvarez Reyes, Rafael, Prieto Ruíz, José A., Sánchez Velazquez, José R., and Mexal, John G.

Abstract

México's incredibly diverse forests are designated by federal regulations as “multipurpose” and managed for the benefit and economic welfare of the local communities. In addition to traditional wood products, the forests provide grazing lands, nonwood forest products, fuelwood, and ecosystem services. Unfortunately, growing populations and the structure of the community forest enterprises are placing increasing stress on forest resources. Furthermore, illegal harvesting, selective logging, routine burning for forage production, and unsuccessful reforestation efforts have depleted forest resources in many regions. Few local communities possess adequate forest nurseries to properly reforest degraded areas. The recent recommitment to nursery production and reforestation by Comisión Nacional Forestal (CONAFOR) should lead to improved stand establishment and growth, especially as forest communities understand the critical link between reforestation and sustained forest productivity. CONAFOR, a federal agency responsible for reforestation programs, has restructured nursery production, reduced the total number of nurseries, and contracted with newly established, private nurseries that now produce 38 million seedlings/year (about 20% of all seedlings produced). The number of community nurseries has shrunk with this greater reliance on private and military (SEDENA) nurseries, which tend to be larger and more sophisticated and use containerized seedlings rather than polybag systems. The objective of this article is to discuss factors leading to these changes and the challenges facing the reforestation program.

10. Focused transhepatic electroporation mediated by hypersaline infusion through the portal vein in rat model. Preliminary results on differential conductivity

Abstract

Spread hepatic tumours are not suitable for treatment either by surgery or conventional ablation methods. The aim of this study was to evaluate feasibility and safety of selectively increasing the healthy hepatic conductivity by the hypersaline infusion (HI) through the portal vein. We hypothesize this will allow simultaneous safe treatment of all nodules by irreversible electroporation (IRE) when applied in a transhepatic fashion.

Abstract

Purpose: The aim of this study was to assess the feasibility of a hybrid ablative technique based on applying electroporation (EP) pulses just before conducting radiofrequency ablation (RFA). The rationale was that the EP-induced reduction in blood perfusion could be sufficient to reduce the thermal sink effect and hence to increase the coagulation volume in comparison to that created exclusively by RFA., Materials and Methods: A modelling study and in vivo experimental study were used. A Cool-tip RF applicator was used both for EP and RFA., Results: Overall, the results did not show any synergy effect from using the hybrid technique. Applying EP pulses prior to RFA did not increase the coagulation zone obtained and the lesions were almost identical. Additional computer simulations provided an explanation for this; the effect of reducing blood perfusion by thermal damage during RFA completely masks the effect of reducing blood perfusion by EP. This is because both thermal damage and EP affect the same zone, i.e. the tissue around the electrode., Conclusions: Our computer modelling and in vivo experimental findings suggest that the combination of EP and RFA with monopolar applicators does not provide an additional benefit over the use of RFA alone.
