El presente aporte se circunscribe a uno de los más serios problemas de la criminalística peruana, el abandono de la poroscopia, disciplina abocada al estudio de los poros presentes en la piel. Para ello, se efectuó el estudio de la literatura nacional e internacional que versa sobre la dimensión teórica de esta rama del saber y la evidencia empírica referida a su aplicación. Se concluyó que, el uso de la poroscopia optimizaría la identificación personal, al reducir varios de los equívocos provocados por el empleo aislado de los dos primeros niveles de análisis dactilar, e incrementaría la fiabilidad de las homologaciones, motivos por los que la misma debe ser implementada a nivel nacional.

Twenty seven homing pigeons (10 males and 17 females) were biometrically studied and the bilateral symmetry (right-left) level was evaluated. Analysed traits were the length of outer external rectrices, length of the wing and length of the second primary feather. The aim of the study was to check whether there is a relationship between the degree of asymmetry level and general health of the birds (expressed as a measure of body condition). Measurements showed a normal distribution and without differences according to the body condition, indicating a high degree of stable growth.

Objective. Understand the perspective of patients in relation to the current way of obtaining an appointment in primary health care. Methods. A bibliography search was performed in the online databases in Spanish and English. The main source was sought by reviewing the bibliographical references of the publications. Results. It was found that the shift to virtuality has made it easier for users to access a primary health care appointment, reducing waiting time and paving the way for non-face-to-face care; the level of user satisfaction has increased positively. Conclusions. Phone and virtual requests are here to stay; these are not intended to replace face-to-face requests, but they are a necessary tool to improve the quality of care for users.

This paper is based on the premise that parole assumes the configuration of rights and the objective was to reach an approximation to the implications of such a postulate in the Peruvian legal system. For that purpose, an analysis of the national and international literature that deals with the dogmatic and applicational dimensions of these figures was carried out. It was concluded that it is not possible to restrict the legal application of early release, regardless of the seriousness of the crime or sentence imposed, and that the concession factors to be legislated must be based on empirical evidence related to recidivism.

The present research aimed to examine whether perfectionism and some demographic variables can predict levels of resilience (and their dimensions) in adults from Venezuela. The design was cross-sectional predictive, through logistic regression analysis. Participants were 313 Venezuelan mature adults (M = 46.44 years), mostly women (82.7%), residents of the interior of the country (70.9%), with higher education (64.2%), and paid employment (67.9%). An adapted version of the Multidimensional Perfectionism Scale (Frost et al., 1990) and the Resilience Scale for Adults (Hernández y Lezama, 2016) was applied via Google Forms. Organization was a positive predictor of resilience and two of its dimensions (OR = 1.13 - 1.27), while fear of mistakes was a negative predictor of resilience and “morality and values” (OR = 0.96). Personal standards positively predicted“perseverance and hope” ...

Cancer is the second leading cause of death in Latin America, and the economic cost it requires will increase markedly in future years (1). If nothing is done about it, cancer incidence and mortality in South and Central America will continue to rise sharply between 2012 and 2035 (2). It is expected that by 2030 the incidence of cancer will increase by 32%, reaching 5 million cases per year (1). At the level of Latin America, health policies have been implemented, where they prioritize the feeding of these patients to reduce the sequelae that the treatments can cause, obtaining optimal results (3). It is in this context that the effects of cancer and its treatment make it difficult to meet the nutritional requirements of patients. Chemotherapy is the most widely used medical treatment for cancer in the world. Knowing that cancer cells tend to grow and divide faster than normal cells, thi...

Objective. To determine the effectiveness of nutritional intervention in beneficiaries of soup kitchens in Lima, 2022. Methods. The study was of an applicative type, specifcally pre-experimental design (without control group) and longitudinal cut. The population consisted of all the benefciaries of the soup kitchens of San Luis. The sample consisted of 110 benefciaries of soup kitchens. Results. The nutritional diagnosis changed positively. Regarding the anthropometric evaluation, the median BMI decreased from 27.95 to 26.04; the MAMC decreased from 30.05 to 28.20 and the PAB decreased from 90.00 to 88.00. In relation to biochemical values, median cholesterol level decreased from 190.20 to 184.10; glucose level decreased from 99.30 to 92.40 and hemoglobin level decreased from 13.30 to 13.20. In relation to bioelectrical impedance, the percentage of fat decreased from 34.00 to 31.00 and...

The use of manual methods to forecast demand in perishable food companies is generally subject to the variability of internal and external factors in the company, causing excess inventories and significant monetary losses, so it is relevant to carry out this research with the objective of to demonstrate that by implementing Machine Learning it is possible to improve the accuracy of the demand forecast. A case study in a company in the poultry sector in Peru, forecasting the last quarter of 2022, based on a real sales database and applying the time series method, comparing the results of the Machine Learning model, and obtaining as a result in a model with high Forecast Accuracy (FA) of 97.56% and a high Forecast Bias (FB) of 2.44%. The research is an important contribution to knowledge, demonstrating that Machine Learning is an ideal tool to project the demand for perishable food product...

Según el INEI, en el Perú en el 2020 se crearon 235.447 empresas y quebraron 45.467. Si no quiere estar en el último grupo, la próxima vez que se le ocurra una idea que pueda terminar en un emprendimiento, no deje de pensar prioritariamente en cómo calcular la demanda de la manera más precisa posible.

En este artículo comparto algunos aspectos que fui conociendo acerca del retablo, en cuanto a sus orígenes, diseño y temática, y que constituyeron un aporte para la realización de mi proyecto en animación en 3D. Asimismo, para tener mayor información sobre este arte, fue necesario recurrir a la fuente de primera mano. Por ello, también incluyo algunos extractos de entrevistas que realicé a los artistas del retablo, las cuales reuní posteriormente en un video documental (Del Río 2011b).

Breast cancer (BC) comprises a group of different diseases characterized by changes in tissue structure and gene expression. Recent advances in molecular biology have shed new light on the participation of genes and their products in the biology of BC. MicroRNAs (miRNAs) are small noncoding endogenous RNA molecules that appear to modulate the expression of more than a third of human genes, and their implications in cancer have grasped the attention of the scientific community. Recently, several studies have described the association between miRNA expression profiles and pathological and clinical BC features. Moreover, these molecules represent a new type of molecular marker that can identify prognosis and guide the management of BC patients. With the increasing understanding of miRNA networks and their impact in the biology of BC, as well as the development of viable strategies to modula...

Cavy production in South America takes place mainly in the Andean regions of Peru, Ecuador, Bolivia and Colombia. Since its domestication (sometime between 3000 and 6000 years ago) the cavy has been used in these countries as a source of animal protein produced with simple handling systems and adapted to the different geographical and cultural contexts. The production of cavies in these countries has grown significantly in the last years due to the promotion of its culinary and nutritional qualities. Also migration of population from rural to urban areas has brought their customs and generated a process of transculturation into the cities, which has turned massive the consumption of cavy meat. The increase in consumption has been accompanied by a growth of supply that, with some differences between countries, has allowed the development of commercial production. This adds new challenges ...
