El objetivo del estudio fue evaluar el efecto de tres protocolos de anestesia balanceada sobre las funciones vitales y el tiempo de recuperación en la ovariohisterectomía felina. Se utilizaron 32 gatas criollas mayores de seis meses (ASA I y ASA II). Los animales fueron distribuidos en tres grupos y recibieron una premedicación similar, pero con inductores diferentes: 3 mg/kg de propofol (n=11), 7 mg/kg de ketamina (n=11) y 5 mg/kg de tiletamina (n=10). Los tres protocolos de anestesia se mantuvieron con isoflurano (1.5% v/v). La monitorización exhaustiva de las constantes fisiológicas fue registrada cada 2 minutos (intra quirúrgico) y cada 4 minutos (posquirúrgico) utilizando un monitor multiparámetro. El efecto de los tres protocolos sobre las funciones vitales y el tiempo de duración se evaluó mediante un análisis de varianza y la prueba de Tukey (α = 0.05). Los protocolos...

OBJECTIVE. To determine the association between body composition and frailty syndrome in elderly people without functional impairment. METHODS. A cross sectional comparative study was made of a sample of 37 frail and 68 non-frail older adults according to the Fried's diagnostic criteria in an urban community of Lima, who underwent anthropometric and bioelectrical impedance measurements. Chi-square test, ANOVA test and Pearson's correlation test was done to predict frailty probability. RESULTS. Significant lower values in weight, height, body mass index, brachial perimeter, subcutaneous skin-fold, muscular arm circumference, fat mass and fat-free mass were found in frail older adults (p = 0,005). There was no correlate between frailty syndrome and fat mass measured by electric impedance and with muscle mass measured by anthropometry. We found a 9 % increased risk per kilogram of less weig...

The study aimed to assess the efficacy of high-intensity interval-training (HIIT) compared to moderate-intensity continuous training (MICT) for 12 weeks on a treadmill on maximal aerobic potency, aerobic resistance, respiratory and heart rate at rest, left ventricle structure and function in dogs. The study design was a blinded controlled clinical trial. Thirty untrained dogs between 12 and 84 months were randomly distributed in the groups: HIIT (n=11), MICT (n=9); and control (n=10). Dogs with cardiovascular, neuromuscular, orthopaedic conditions, body condition score over 7, or any abnormalities that impaired exercise performance were excluded. Before and after the programme, dogs performed an incremental exercise test to determine the maximal velocity (Vmax) and velocity at lactate threshold (VLT). Respiratory and heart rates and left ventricular chambers and systolic function at rest...

Tourist activity in Mazatlán, Mexico involves various attractions, including the consumption of raw seafood, which leads to a greater risk of infections transmitted by microorganisms, since tourists are unaware of the dangers. The study aims to assess nutritional status and its association with gastrointestinal diseases in tourists hospitalized during the period 2014 - 2018 in Mazatlán Sinaloa. This research is retrospective with a quantitative and cross-sectional approach, based on a non-experimental, descriptive, and correlational design. The technique used was anthropometric and a validated survey of dietary practices for seafood consumption on the clinical records of 96 patients from a private hospital in Mazatlán. Biochemical parameters such as glucose, hemoglobin, cholesterol, and triglycerides were reviewed, and anthropometric parameters of weight and height with BMI calculatio...

The objective of this study was to fit four nonlinear models (Brody, von Bertalanffy, Gompertz and Logistic) to realizations of llama weight, using frequentist and Bayesian approaches. Animals from both sexes and types (K'ara and Ch'accu) were observed. Data consisted of 43,332 monthly body weight records, taken from birth to 12 months of age from 3611 llamas, collected from 1998 to 2017 in the Quimsachata Experimental Station of the Instituto Nacional de Innovación Agraria (INIA) in Peru. Parameters for Non-linear models for growth curves were estimated by frequentist and Bayesian procedures. The MCMC method using the Metropolis-Hastings algorithm with noninformative prior distributions was applied in the Bayesian approach. All non-linear functions closely fitted actual body weight measurements, while the Brody function provided the best fit in both frequentist and Bayesian approaches ...

El cáncer es una enfermedad que afecta tanto a humanos como animales domésticos y silvestres. Cada célula y año de vida adicional deberían aumentar la probabilidad de carcinogénesis, sin embargo, la tasa de ocurrencia de cáncer no está en función directa con el tamaño del animal. La paradoja de Peto señala que no hay asociación entre el tamaño corporal, la longevidad y el riesgo de cáncer entre las especies y predice que los animales con un gran tamaño corporal desarrollarían mecanismos únicos para evadir el cáncer. Se han planteado distintas hipótesis para resolverla y si bien entre ellas se ha mencionado a los genes de reparación del ADN, estos no han sido investigados de manera específica y a un nivel estructural y funcional de sus proteínas. La reparación del ADN es un mecanismo que evita la acumulación de mutaciones en el genoma y sus vías son altamente cons...

Many pathological conditions are closely related with an increase in tissue sti ness. For many years, experts performed manual palpation in order to measure elasticity changes, however, this method can only be applied on superficial areas of the human body and provides crude sti ness estimation. Elastography is a technique that attempts to characterize the elastic properties of tissue in order to provide additional and useful information for clinical diagnosis. For more than twenty years, di erent research groups have developed various elastography modalities with a strong interest for quantitative images during the last decade. Recently, comparative studies among di erent elastographic techniques have been performed in order to better characterize biomaterials, to cross-validate several shear wave elastographic modalities and to study the factors that influence their precision and accur...

The authors, on the basis of the importance of the activities of constitutional courts in the system of separation of powers in most countries, propose a comparative legal analysis of the normative and legal acts governing the procedure for the adoption and legal nature of decisions of these bodies. On the basis of the study of the legal consolidation of the activities of the constitutional courts, it was concluded that the decisions of the constitutional courts, possessing such characteristics as the possibility of abolishing the legal norm; the final character; the obligation of execution for all state authorities, organizations and citizens; and the moral authority, perform a law-making function, establish rules governing important relations in society and play a special role in ensuring and protecting fundamental human and civil rights and freedoms plays an important role in ensuring...

The World Trade Organization (WTO) dispute settlement system is currently in crisis because the WTO Appellate Body ceased effectively functioning in December 2019. As a consequence, the WTO Dispute Settlement Body is unable to adopt a panel report if a party to the dispute notifies its intention to appeal. In this context, this article analyzes what factors may influence the complaining parties’ decision on whether to recur to two regional trade agreements (RTA), namely the Pacific Alliance and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), as alternative fora to WTO dispute settlement. After a comparative analysis of dispute settlement rules in both RTAs and the WTO Dispute Settlement Understanding, we conclude that procedural and institutional factors will arguably be relevant for complaining parties that wish to select a dispute settlement forum.

Respect for the principle of “due process” in the administrative procedure envisaged for the application of the prohibitions on anticompetitive behavior established in Peru’s antitrust regulations before Indecopi is called into question due to the lack of separation between the investigative body (Technical Secretariat of the Commission of Free Competition) and the decision-making body (Commission of Free Competition). This article examines the issue from three perspectives. First, from the functional economic perspective, the organization and the administrative sanctioning procedure provided for in the Peruvian antitrust legislation are part of the public enforcement model that entrusts Indecopi (an agency divided into two units) with the enforcement of the prohibitions of anticompetitive conduct. Inevitably, this may lead to a confirmation bias (prosecutorial bias) -conscious or ...

A problem caused by the geography of Peru, among others, is the height. Much of our population lives several thousand meters above sea level in low barometric pressure and chronic anoxia, which impacts on your body produce organic and functional changes, making the man of the Andes corresponds to anthropological not found in other race, with innate and acquired characteristics that differentiate the inhabitant of the plain. Comparative studies between man and high sea level, remains inexhaustible field addressed primarily by Schools Monge, Hurtado Guzmán Barrón and other investigations.
