Potential Tool

Blood feeding insects have to rely on the protein content of mammalian blood to insure reproduction. A substantial quantity of protein is provided by hemoglobin present in erythrocytes. Access to hemoglobin is accomplished only via erythrocyte lysis. It has been shown that midgut homogenates from the blood feeding stable fly, Stomoxys calcitrans, contain free fatty acids and it was proposed that these detergent-like compounds play a major role as hemolysins in the digestive physiology of this species. More recently sphingomyelinase activity was detected in midgut preparations of this fly, which would provide a potential tool for the enzymatic cleavage of the erythrocyte's membrane sphingomyelin. The action of specific hemolytic factors should affect the erythrocyte's morphology. The shape of bovine erythrocytes undergoing in vitro hemolysis by crude midgut homogenates from the stable fly was examined by scanning and transmission electron microscopy.

Invertebrate Larvae

The functional properties of marine invertebrate larvae represent the sum of the physiological activities of the individual, the interdependence among cells making up the whole, and the correct positioning of cells within the larval body. This chapter examines physiological aspects of nutrient acquisition, digestion, assimilation, and distribution within invertebrate larvae from an organismic and comparative perspective. Growth and development of larvae obviously require the acquisition of “food.” Yet the mechanisms where particulate or dissolved organic materials are converted into biomass and promote development of larvae differ and are variably known among groups. Differences in the physiology of the digestive system (secreted enzymes, gut transit time, and assimilation) within and among feeding larvae suggest the possibility of an underappreciated plasticity of digestive physiology. How the ingestion of seawater by and the existence of a circulatory system within larvae contribute to larval growth and development represent important topics for future research.

Risk Of Aspiration

Abstract Background Rapid Sequence Induction (RSI) was introduced to minimise the risk of aspiration of gastric contents during emergency tracheal intubation. It consisted of induction with the use of thiopentone and suxamethonium with the application of cricoid pressure. This narrative review describes how traditional RSI has been modified in the UK and elsewhere, aiming to deliver safe and effective emergency anaesthesia outside the operating room environment. Most of the key aspects of traditional RSI – training, technique, drugs and equipment have been challenged and often significantly changed since the procedure was first described. Alterations have been made to improve the safety and quality of the intervention while retaining the principles of rapidly securing a definitive airway and avoiding gastric aspiration. RSI is no longer achieved by an anaesthetist alone and can be delivered safely in a variety of settings, including in the pre-hospital environment. Conclusion The conduct of RSI in current emergency practice is far removed from the original descriptions of the procedure. Despite this, the principles – rapid delivery of a definitive airway and avoiding aspiration, are still highly relevant and the indications for RSI remain relatively unchanged.

Different Levels

Background: -Video-based teaching, a distance learning tools is widely beingused in the present COVID-19 pandemic. Present study compares cognitive and affective domains learning outcomes between traditional and video-based physiology lecture. Methods and material: -A total of 25female students of Applied Medical College, Prince Sattam bin Abdul Aziz University, kingdom of Saudi Arabia during 2019 were selected for the study. Physiology course consist of 45 credit hours in a fifteen-week semester. Students were evaluated by various methods for different levels of cognitive and affective domains between traditional method of endocrine physiology lecture session and video-based digestive physiology lecture session. Marks obtained by each student in all the assessment methods of cognitive and affective domains were calculated to get a total mean score and expressed in percentage and compared between the traditional and video-based physiology lecture. Results: -The total mean score for all the assessment methods of the cognitive domains in the digestive physiology lecture with video was 70% and endocrine lecture without video was 50%.The total mean score for affective domain in the digestive physiology lecture with video was 80% and endocrine lecture without video was 50%.Cognitive domain show no major difference between traditional endocrine physiology and video-based digestive physiology lecture, while student performance was good for affective domain in the lecture supported by video. Conclusion: -Video-based teaching helps the learner to achieve objectives of the different levels of affective domain compared to cognitive domain as well as compared to traditional lecture with no video.
