Serum anti-Mullerian hormone and homocysteine in premenopausal females with and without cardiovascular disease

Background: The objective of this study is to assess the association of anti-Mullerian hormone (AMH) and homocysteine (Hcy) levels in premenopausal females with and without cardiovascular disease.Methods: A case control study was conducted in premenopausal, menopausal and normal fertile females (n=30) with and without cardiovascular disease in a tertiary care hospital and research centre in central India. Fasting sample obtained was assessed for AMH and Hcy levels. Results were compared and data was analyzed.Results: The levels of AMH and Hcy were significantly altered in premenopausal and menopausal females as compared to normal fertile females. Moreover, there was a weak correlation when intergroup comparison was made between the parameters in females with and without cardiovascular disease.Conclusions: A prospective study with a larger sample size to assess levels of AMH need to be performed to provide insight in premenopausal females for the early detection cardiovascular disease

Folk Physics in the Twenty-first Century: Understanding Tooling as Embodied

Povinelli’s (2000) studies with chimpanzees (Pan troglodytes) reported in “Folk Physics for Apes” were firmly grounded in a Cartesian view of knowledge, which posits that humans use abstract concepts such as force, gravity, and shape to reason causally about events and plan our actions (with tools in the case of Folk Physics for Apes). Povinelli set out to examine if chimpanzees, like humans, used causal concepts to solve mechanical problems, as the Cartesian view predicts. However, Povinelli’s findings uniformly challenged his expectations. Povinelli’s book stimulated research and contributed to the development of alternate understandings of how animals (including humans) use tools. We summarize one alternative approach, Ecological psychology, elucidate how predictions drawn from this approach, explain (post hoc) the findings presented in Folk Physics for Apes, and suggest directions for continuing work on this topic from an Ecological approach. Ecological psychology posits direct perception and requires analysis of the animal-task-environment system, thus providing a distinct alternative to the Cartesian approach. Twenty years on, Povinelli’s elegant exposition in Folk Physics for Apes of the Cartesian view of how animals use tools, and his efforts to explain the findings of his experiments in this framework, still stimulate those who study animal behavior and cognition from different theoretical perspectives

Motion of falling object

A simple setup was assembled to study the motion of an object while it falls. The setup was used to determine the instantaneous velocity, terminal velocity and acceleration due to gravity. Also, since the whole project was done within $20 it can easily be popularized.Comment: 11 pages, 4 figur

Is English language as a medium of instruction a hurdle for first year MBBS teaching learning? Perceptions of students and teachers

Background: Presently there is a linguistic dualism i.e. thinking in one language and studying in the other. Proficiency in English is the need of the hour. However, for some an abrupt change in the medium of language along with introduction of terminologies can become a potential barrier to academic success.Methods: A questionnaire based study was carried out in 150 students and 25 teachers of first MBBS.Results: Majority of the students and teachers considered that English as a medium of instruction is not a problem. They also opined that English should be retained as a medium of instruction since it is of global importance; use of regional /national language should be allowed since it will help in dealing with patients and thus better patient care.Conclusions: Since English is the language of global importance, medical teachers should work together to find out a practical approach in addressing some of the problem areas faced by few medical students to help them perform better as an Indian medical graduate

Noncommunicable and Communicable Diseases: Finding Common Ground

As the world grapples with unprecedented health challenges, such as coronavirus disease 2019 (COVID-19) and now monkeypox, the focus on traditional concerns, like maternal and child health, and relatively newer pandemics, e.g., diabetes and obesity tend to get diluted. This is especially concerning in countries which face a dual challenge of both communicable and noncommunicable diseases (NCDs). In this article, we list the factors that are common to both communicable disease and NCDs, and suggest measures to integrate procedures for their screening, management and prevention

How capuchin monkeys use their semi-prehensile tails

Among primates, prehensile/semi-prehensile tails have evolved independently in the families Atelidae and Cebidae of the infraorder Platyrrhini (Neotropical monkeys). They facilitate maintaining stability during locomotion on thin, flexible branches and while reaching for food on challenging substrates. How a prehensile/semi-prehensile tail is coordinated with the hind limbs to facilitate controlled, flexible adoption of postures remains unknown. In an experimental set-up in the wild, we induced capuchin monkeys to adopt a tail-assisted, head-down tripodal posture to reach for food, documenting from slow-motion video recordings (120 fps) both qualitative changes in the monkeys’ positional behaviour – the relative orientation of their limbs and semi-prehensile tail – and quantitative changes in the left knee angle. The monkeys coordinated their tail and hind limbs in an online manner by preparing to anchor the tail over a substrate when beginning to adopt a tail-assisted, head-down, tripodal posture, but anchoring it only at the moment when they extended their hand to grasp the food. Coordination of their semi-prehensile tail with their limbs enables these capuchin monkeys to adjust their posture more flexibly compared to anchoring their tail over a substrate in anticipation and subsequently changing posture

On the psychological origins of tool use

The ubiquity of tool use in human life has generated multiple lines of scientific and philosophical investigation to understand the development and expression of humans' engagement with tools and its relation to other dimensions of human experience. However, existing literature on tool use faces several epistemological challenges in which the same set of questions generate many different answers. At least four critical questions can be identified, which are intimately intertwined-(1) What constitutes tool use? (2) What psychological processes underlie tool use in humans and nonhuman animals? (3) Which of these psychological processes are exclusive to tool use? (4) Which psychological processes involved in tool use are exclusive to Homo sapiens? To help advance a multidisciplinary scientific understanding of tool use, six author groups representing different academic disciplines (e.g., anthropology, psychology, neuroscience) and different theoretical perspectives respond to each of these questions, and then point to the direction of future work on tool use. We find that while there are marked differences among the responses of the respective author groups to each question, there is a surprising degree of agreement about many essential concepts and questions. We believe that this interdisciplinary and intertheoretical discussion will foster a more comprehensive understanding of tool use than any one of these perspectives (or any one of these author groups) would (or could) on their own

How tufted capuchin monkeys (Sapajus spp.) and humans (Homo sapiens) handle a jointed tool.

The embodied theory of tooling predicts that when using a grasped object as a tool, individuals accommodate their actions to manage the altered degrees of freedom in the body-plus-object system. We tested predictions from this theory by studying how 3 tufted capuchin monkeys (Sapajus spp.) and 6 humans (Homo sapiens) used a hoe to retrieve a token. The hoe’s handle was rigid, had 2 segments with 1 planar joint, or had 3 segments with 2 (orthogonal) planar joints. When jointed, rotating the handle could render it rigid. The monkeys used more actions to retrieve the token when the handle had 1 joint than when it had no joints or 2 joints. They did not use exploratory actions frequently nor in a directed manner in any condition. Although they sometimes rotated the handle of the hoe, they did not make it rigid. In a follow-up study, we explored whether humans would rotate the handle to use a 2-jointed hoe in a conventional manner, as predicted both by the embodied theory and theories of functional fixedness in humans. Two people rotated the handle to use the hoe conventionally, but 4 people did not; instead, they used the hoe as it was presented, as did the monkeys. These results confirm some predictions but also highlight shortcomings of the embodied theory with respect to specifying the consequences of adding multiple degrees of freedom. The study of species’ perceptual sensitivity to jointed object’s inertial properties could help to refine the embodied theory of tooling. (PsycInfo Database Record (c) 2021 APA, all rights reserved
