Seasonal and altitudinal variation in dorsal skin reflectance and thermic rates in a high-altitude montane lizard.

Temperature is one of the most important factors in the life histories of ectotherms, as body temperature has an undeniable effect on growth, activity, and reproduction. Lizards have a wide variety of strategies to acquire and maintain body temperature in an optimal range. The "Thermal Melanism Hypothesis" proposes that individuals with lower skin reflectance can heat up faster as a result of absorbing more solar radiation compared to lighter conspecifics.

A Polyherbal Mixture with Nutraceutical Properties for Ruminants: A Meta-Analysis and Review of BioCholine Powder.

BioCholine Powder is a polyherbal feed additive composed of , , , and . The objective of this study was to analyze published results that support the hypothesis that the polyherbal product BioCholine Powder has rumen bypass choline metabolites through a meta-analysis and effect size analysis (ES). Using Scopus, Web of Science, ScienceDirect, PubMed, and university dissertation databases, a systematic search was conducted for experiments published in scientific documents that evaluated the effects of BioCholine supplementation on the variables of interest.

Thermoregulatory behavior varies with altitude and season in the sceloporine mesquite lizard.

In ectothermic animals, body temperature is the most important factor affecting physiology and behavior. Reptiles depend on environmental temperature to regulate their body temperature, so geographic variation in environmental temperature can affect the biology of these organisms in the short and long term. We may expect physiological and behavioral responses to temperature change to be especially important in ectotherms inhabiting temperate zones, where different seasons present different thermal challenges.

Altitudinal variation in organ mass from three mountain systems: The case of mesquite lizard Sceloporus grammicus.

High altitude environments provide a fertile ground for investigating the benefits of phenotypic adjustments at several levels of biological organization. Low oxygen partial pressure and low environmental temperature are the main limiting factors that promote phenotypic variation in different organs, such as the lung and heart. Although high-altitude environments act like natural laboratories, most morphological studies conducted to date lack replication.

Elevation and blood traits in the mesquite lizard: Are patterns repeatable between mountains?

Ecogeographical patterns describe predictable variation in phenotypic traits between ecological communities. For example, high-altitude animals are expected to show elevated hematological values as an adaptation to the lower oxygen pressure. Mountains act like ecological islands and therefore are considered natural laboratories.

Influence of a Polyherbal Choline Source in Dogs: Body Weight Changes, Blood Metabolites, and Gene Expression.

Choline chloride is used to provide choline in dog foods; however, in other domestic species, it has been replaced with a polyherbal containing phosphatidylcholine. A polyherbal containing , , , , and was evaluated in adult dogs through body weight changes, subcutaneous fat thickness, blood metabolites, and gene expression. Forty dogs (4.

Medical consultation, time and duration.

This essay is a reflection of the time and duration of the medical consultation, seen as a social process that is determined by macro structures following the productive logic and the demands of modern time. The length of the medical discussion is heterogeneous worldwide; in contrast, what is standard is the perception of the professionals and the patients that the time for interaction is short. Such a perception pervades the doctor-patient relationship, perpetuating a cycle of dissatisfaction-tension-anxiety in these actors.

The feeding-nutrition connection, three aspects for its understanding.

Feeding is not an isolated concept; it is linked to biological, psychological, cultural, political and economic determinants. Physiologically the meeting of the biological need is very important, but when a group is subjected to a diet that only satisfies hunger and does not provide for nutrients, chronic deficient nutritional stages appear that impact social welfare and health. In this paper, we present three instances of nutritional problems that affect the Mexican population: child malnourishment, obesity and food security.

Identification of mitochondrial DNA transfer in canine transmissible venereal tumours obtained from dogs in Mexico.

Canine transmissible venereal tumour (CTVT) has been transmitted by cell transplantation from dog to dog, for over 10 000 years. Although initial studies report a single genetic origin for CTVT, recent samples from around the world reveal high genetic diversity. An elevated number of polymorphisms have been determined in mitochondrial DNA (mtDNA) of CTVT.

Violence in Mexico: A social or public health problem?

This article seeks to explain the importance of violence as a social phenomenon and public health, trying to envision this issue not only from a curative approach to health, but from the social determinants of health, such as economics, politics and the administration of justice. Here, the younger population lacks real opportunities with an “absent State” that fails to provide structure. These frameworks play a fundamental role in the manifestation of violence.

[Stock based medicine: the patient waiting in a weary medical procedure].

This essay attempts to bring on a new perspective for healthcare professionals regarding the problems that surround this institutionalized profession, based on a system of stock balances and not on the real needs of patients and their community. The healthcare professional not only engages in biomedical healing but also possesses knowledge and expertise regarding the dialectical process of health/disease. Thus, his or her practice and actions should be centered on social practices and not just the healing process.

[Thanatophoric dysplasia: case-based bioethical analysis].

This paper presents a case report of thanatophoric dysplasia diagnosed in the prenatal period using ultrasound standards. The course of the case pregnancy, birth process, and postnatal period is described. This report invites bioethical analysis using its principles, appealing to human dignity, diversity and otherness, particularly in the mother-child dyad and their family.

[Family medicine and practice in the Mexican Social Security Institute].

The central ideas of this research paper are related to the practice of family medicine as a specialty. It focuses in its origins, problems, unique characteristics, limitations, scope, management, and processes within the context of primary care of the Mexican Social Security System. This approach was based on a qualitative, hermeneutical study closely related to the Structural Functionalism Theory.

[Clinical experience with a C-section surgical technique in patients with morbid obesity: a case series].

Obesity is a public health challenge that has crossed into the area of reproductive health. An obese pregnant woman has multiple complications before, during, and after pregnancy. Likewise, cesarean section is more difficult and has slower recovery times in this group of patients.

[Benign tumors of vulva: review and case report of achrocordon].

The vulvovaginal region is a very complex area because of its anatomy and the fact that it can be source of a large number of benign tumors and less frequent malignant tumors. In recent decades, there have been significant gains in the diagnosis and treatment of vulvovaginal tumors, thanks to the contributions of cellular and molecular biology. The purpose of this review article is to serve as a practical reference for clinical and pathological diagnosis as well as in the outpatient treatment and monitoring of these benign tumors.
