The main objective of the research was to characterize the innovation network and estimate an innovation adoption rate to evaluate its relationship with income generation in quinoa producers in Cabana. The characterization of the innovation network has been carried out using the social network analysis methodology (SNA), the innovation adoption index (IAI) has been obtained through an ordinal measurement scale and the return of the level of adoption of innovations on Producers' income has been estimated using the two-stage least squares methodology (TSLS) through the data obtained in a survey of 268 producers. The weak articulation of social capital has been evidenced in Cabana quinoa producers; however, the network of customers and input suppliers is well defined. Most of the producers stand out for their innovations in the productive component, the main weakness is related to the scarce innovation in the administration component. For each level of innovation adopted, a return of 49.09% on the income of the producer has been estimated, showing that the adoption of innovations has a greater impact on the generation of economic income compared to the years of schooling that only reaches 7.8%.

The research was carried out in the alpaca production unit of the Tomas Peasant Community, of the Lima Region, with the aim of identifying the floristic component of the pasture of a wetland area in the dry season of the year and the species that were most consumed by alpacas. Previously, the floristic inventory of 5 hectares of pasture was carried out and 10 mother alpacas and 10 tuis alpacas were assigned. During the study period, stool samples were taken to evaluate the diet by the microhistological method. The chemical components of the six main species of grasses most consumed were analyzed. In the initial inventory 36 species were found, of which the most consumed were 10 that made up approximately 80% of the diet. Chemical analysis shows a crude fiber content in a range between 66,23 to 77,24%, crude protein between 2.49 to 5,21% and vitamin A between 0,08 to 0,37 mg / 100g. The contribution of the present is to identify the species of pasture most consumed by alpacas tuis and mothers, in order to take care in their conservation.

The Andean region has always fascinated travelers and scholars who are interested in biodiversity. Monumental works have been written on mineral resources, flora and fauna. And efforts are being made to protect the richness of biodiversity, especially in protected natural areas. But the threats from the advance of extractive activities and the consequences of climate change are becoming more and more shocking and are avoiding the achievement of sustainable development. For this reason, the production of knowledge and its spread in quality scientific journals is an urgent need, based on data from reality itself and its resources, in light of the scientific literature produced. In this scenario, the Highlands Research Journal wishes to invite everyone to contribute with their proposals to face the challenge of environmental degradation, the exploitation of natural resources, the effects of climate change and the persistence of socio-environmental conflicts, of which it is essential to take into account social facts, in the search for possible solutions to achieve the balance between man and nature and guide activities towards the conservation, rational and sustainable use of natural resources. History is full of lessons that should not be forgotten, about the wealth of Andean natural resources and the enormous body of knowledge that traveling scientists have left us in recent centuries.

The effect of initial population density (Pi) of the peanut root-knot nematode, Melodoigyne arenaria, on curly leaf parsley growth was assessed in this study. The population densities of M. arenaria ranged from 0 to 64 eggs + second-stage juveniles (J2)/cm3 soil in sterile sandbags. The root gall index (RGI), reproduction factor (RF), fresh leaf weight (FLW), dry leaf weight (DLW), root fresh weight (RFW), root length (RL), leaf height (LH), and chlorophyll index (SPAD) were determined at 90 days after inoculation. FLW, DLW, RFW, LH, and SPAD data were fitted to the Seinhorst equation, y = m + (1 - m) zPi-T, to determine the tolerance limit T = 0.25 eggs +J2/cm3 soil for FLW, DLW, RFW, and LH, with relative means (m) of 0.52, 0.24, 0.22, and 0.4 respectively; conversely, the T value for SPAD was 0.125 eggs + J2/cm3 soil and with a m of 0.26. All biometric variables decreased with an increase in the initial population density (Pi). Nevertheless, the highest RF of M. arenaria in parsley was 78.92 for a Pi = 8 eggs + J2/cm3 soil, with an RGI value of 5 from Pi = 1 eggs + J2/cm3. Curly leaf parsley growth decreased with an increase in Pi of M. arenaria.

Predictive microbiology is an interesting tool that allows evaluating the behavior of biomass and metabolites in different culture media, providing multiple benefits, whether scientific or industrial, for these and other reasons the objective of this research was to evaluate applied sigmoidal kinetic models to the growth of Saccharomyces boulardii in milk. For this purpose, flasks were prepared with 200 mL of fresh cow's milk, previously sterilized at 121 ° C x 15 min, then the strains were inoculated at a temperature of 37 ° C and incubated at the same temperature under constant shaking of 20 revolutions per minute (rpm) in a water bath with shaking, for 7 h; To construct the curves and obtain the growth constants, colony-forming units were counted per milliliter (cfu / ml) at one-hour intervals, with a monocular microscope and Neubauer chamber. Also, the pH and titratable acidity expressed in lactic acid were measured. The data obtained were converted to a logarithmic scale to apply the sigmoidal equations of Gompertz, Logistic, Modified Logistic and Weibull. The results of the kinetic modeling gave us that the modified Logistics and Logistics models presented a better fit compared to the rest. Likewise, the Weibull model presented the lowest value of adjustment, on the other hand, in the analysis of the statistical criteria, all models except Weibull present similarity. Finally, each sigmoidal model allowed to evaluate the growth of Saccharomyces boulardii with each of its kinetic constants.

Chagas disease, a parasitic infection caused by the protist Trypanosoma cruzi, affect the poorest populations, living in remote, rural areas and urban slums. Although this drug is effective against Chagas disease present a number of serious side effects. In residents of high Andean areas with megacolon it can lead to cardiomyopathies. The aim of this study was to investigate whether dietary supplementation with L-glutamine may alleviate some of these symptoms because of its previously observed anti-inflammatory properties. We studied two groups of T. cruzi-infected mice receiving treatment with nifurtimox. One group was fed the standard diet, while the other group’s diet was supplemented with Glutamine. We found that Glutamine supplementation increases body weight (p<0.001), decreases heart mass to body mass ratio (p<0.001), and decreases the number of amastigotes present in cardiac tissue. Additionally, histopathological analysis showed less heart tissue damage in the group that received Glutaminne in their diet. Therefore, our findings suggest that Glutamine supplementation improves nifurtimox treatment outcomes of T. cruzi infection.

The objective of the study was to investigate the antimicrobial activity of tunta on Salmonella enterica subspecies enterica serovar Typhimurium. A natural isolate of this bacterium was used that was resistant to chloramphenicol. The experiment required the preparation of a standard solution of 0,8 g / ml of tunta extract. The Kirby Bauer technique was used for the antimicrobial evaluation of the tests and the Duraffourd scale to measure the level of sensitivity. Resulting, for the ten technical repetitions of the experimental group, an average halo of 10,40 mm and a standard deviation of 0,63 of DHI (level of limit sensitivity, according to said scale). In conclusion, our work shows evidence that tunta has an antimicrobial effect at a borderline sensitivity level on Salmonella enterica subspecies enterica serovar Typhimurium. After more in-depth research, this derivative of Solanum Jueepczukii could become an alternative for the development of antibiotics of natural origin and allow a sustainable development of Andean cultures.
