A large fire of 233 ha in Huascarán National Park in Peru provided an opportunity to compare plant and bird responses in burned and nearby unburned zones of the puna. Heights and live diameters of flagship Puya raimondii rosettes(assigned to four broad developmental phases), plant communities(66 species in 24 families and nine growth forms) and bird communities(77 species in six trophic guilds) were monitored after the fire. Although no mortality was observed, Puya raimondii plants were affected by the fire, losing approximately 60% of their photosynthetic area across all developmental phases, but recovered quickly during the first two years after fire. The comparison of Puya rosette recovery after fire was complicated by the changes in live rosette diameter for unburned plants, which showed plasticity of photosynthetic area linked to seasonal and annual fluctuations in precipitation in this relatively dry environment(decreased by 26% for mature adult plants over the study period). Fire caused an immediate change in the density, biomass and composition of vegetation. Although the species present remained similar, their abundances changed significantly immediately after the fire, with notable reductions in dominant tussock grasses. This provided opportunities for other plants, resulting in higher postfire diversity of plant species, genera, families and growth forms. In turn, the changes in vegetation after fire affected the composition of birds according to their trophic guild. Granivores largely disappeared,generalists were mostly unaffected, and other guilds showed a more complex response. As the vegetation recovered, most displaced birds returned within approximately one year.

Cold plasma at room temperature and pressure is an emerging and novel tool for the inactivation of cell derived from its ionic energy,which is capable of breaking bonds such as carbon-carbon,carbon-hydrogen,carbon-oxygen,among others,these being the ones that support the biological structure of microorganisms.This work tries to create its own infrastructure that includes a high voltage source,an infrared trigger which reduces the effect of the ozone created,an ionic reactor in which the plasma acts at atmospheric temperature and pressure,and a magnetic field that allow aligning the plasma to the combined processes that are carried out.

First Total Posterior Craniopagus Twins in Central African Republic: Two Years Challenge of Management

Introduction: Countries with limited resources have real difficulties in separating craniopagus twins. Separation surgery cannot be considered there due to lack of technological conditions and appropriate means. Objective: To show the benefits of an Italian-Central African humanitarian collaboration, after two years follow-up, aiming to improve the first childhood years of craniopagus twins, born in the Central African Republic and separated in Rome. Case Report: The two female conjoined craniopagus twin, born at term on June 29, 2018 in Mbata located about 96 km from Bangui (CAR), were referred to the neonatology unit of the CHUPB on their 3rd day of life. The mother was 31-year-old, gravida 4 and para 5. Prenatal cares were quantitatively and qualitatively poorly followed. The diagnosis of posterior conjoined craniopagus twins associated with early neonatal infection was retained. After seven days of antibiotics and regression of infectious symptoms, the newborns were kept in the neonatology unit for a closer follow-up, pending the completion of administrative procedures for a medical evacuation as part of the international humanitarian activities of the Pediatric Hospital of the Holy Seat in collaboration with the Pediatric Teaching Hospital in Bangui. Finally, the twins were transferred to the Bambino Gesu Hospital in Rome on September 10, 2018 where the 3D images confirmed the total posterior fusion. Between May 2019 and June 2020 thirty hours of interventions allowed a step-by-step separation of the twins, with a gradual rerouting of the shared blood supply, remodeling and re-creating a skin to cover the skull bones. No postoperative compli
