- Work Virtual Education Supplement: Virtual Campus Platform USC
In the lectures, audiovisual media will be used together with teacher oral explanations. Sporadically the teacher can interact with students asking questions for your immediate reply, and periodically (monthly) be requested in writing the answers to all students.
*The interactive Computer Practice (TOXI OR):
Title: Experimental Toxicological Evaluation: Determination of the LD50 in acute toxicity tests. (4 h)
Activities done in the computer room allocated. It consists of 3 parts.
1st. Students will visit the animal house in a virtual manner.
2nd. In the computer room (capacity of 20 students) will explain the practice protocol, initiated a literature about a proposed acute toxicity test and based on the determination of the LD50 of a substance. According to this protocol, we apply data from 20 doses of a substance and the resulting number of dead animals. They proceed to solve the problem individually, using a computer and applying Excel software: calculations and graphical representations leading to the determination of the LD50 value.
3rd. Exercises proposed to solve individually.
*The interactive classes of Laboratory Practices (TOXI LB):
TOXI LB1. National and European regulations on the handling and use of hazardous chemicals. (4 h)
Activities done, in the Toxicology laboratory :
Classification of substances by hazard, taking into account the legislation. Applications of these concepts in Laboratory (labels, hazard pictograms, H phrases and P phrases, cards of safety data, FDS).
TOXI LB2. Qualitative Toxicological Analysis. Systematic Toxicological analyisis. Qualitative Toxicological Analysis of bipiridilic herbicides: paraquat and diquat. (4 h)
Activities done in the Toxicology laboratory:
-Systematic Toxicological Analysis: this part of the practice is based on the initial performance of a generic extraction of the sample (urine), for acidic, basic and neutral compounds. Subsequently, the isolated toxins are identified by thin layer chromatography, using specific revealers to complete the identification.
-Qualitative Toxicological Analysis of bipiridilic herbicides: A qualitative colorimetric test useful for the detection of bipyridyl herbicides in biological samples is carried out. Although, in practice, it is usually applied to urine samples, it is also possible to use it in other biological samples. All this is commented and discussed, as well as the diagnostic and prognostic usefulness of the test used.
These issues, in addition to the laboratory part of the practice, are usually complemented with exercises aimed at reinforcing the calculations to adequately prepare the different solutions necessary to carry out the analysis. The acquisition of safe work habits in the laboratory is reinforced across the board in all practices. Likewise, the practices are related to real situations in which the knowledge acquired is applied. For this, clinical cases of intoxications with these drugs are also search by the students and discuss.
*The interative Not assistance Clinical Practices (TV C):
TOXI C1. Title: General analytical toxicology research, collection and submission of samples, instrumental resources, and Veterinary Toxicology Information Service (SATVe). (4 h)
Activities done: In the classroom-Toxicology Seminar and they consist of 2 distinct parts.
1. Those protocols that must be into account to achieve a good diagnosis from the perspective of analytical toxicology are presented to students. Sampling: type (biological, drinking water, food, and other materials), suitable material to be used, chain of custody, cold storage, ways of sending samples to the laboratory, etc.. Analytical methodology applied: samples organic, inorganic, gases, etc. Interpretation of results by the clinician. Identification of toxic. Proposal for individualized resolution and/or group of case studies: diagnosis and treatment, for which the student will handle some tables made in the department.
2. Presentation to students of a database developed by our department to be used by a Veterinary Toxicology Service. Through browsing its various parts, students will discover their utilities and applications in clinical practice. Basically it has two parts, which are interconnected. On the one hand, it is a database of information, data or veterinary clinical toxicological knowledge. On the other, this software includes a file of cases. When you create a tab on the occasion of a new case that is consulted to SATVe, the information contained in the first part can be used and consulted, which can be very helpful.
TOXI C2. Diagnosis of paracetamol poisoning in small animals. Quantitative analysis by visible spectrophotometry. (4 h).
The activities will be developed in the Toxicology seminar classroom and in the Laboratory, and consists of 2 parts:
1ª Several clinical cases of paracetamol poisoning in cats and dogs are presented. Based on the clinical signs and/or pathology findings described and making use of the information provided in the lectures, the main findings found in the intoxications caused by this drug, as well as its mechanism of action, are discussed with the students.
The possible instrumental techniques to carry out the qualitative analysis to confirm the intoxicating agent, as well as the quantitative analysis, will be discussed.
2ª Through the laboratory analysis, the suspected diagnosis of a possible case of paracetamol poisoning will be confirmed. To do this, the students will perform the quantitative analysis of paracetamol by visible spectrophotometry. Subsequently, the results will be interpreted based on the concentration obtained in the test sample.
The Continuous Evaluation System for those students with partial exemption (expository classes) granted based on Instruction No. 1/2017 of the General Secretariat will be the same as for all students. Being able to reach the maximum of 10% awarded to all students through online expository controls, or through an in-person online test with the final exam.
To OVERCOME matter, in the system of continuous assessment, is compulsory the assistance and active participation in:
* Participative attendance of the Lectures through controls in the Expository Classes as "progressive evaluation" to obtain a maximum score of 10 %. Theoretical Controls will be carried out with an approximate monthly periodicity and within the hours of the Lecture activity of the subject.
* Interactive Computer Classes, Laboratory Classes and Non-Assistance Clinics work (Practices), including the presentation of a Practice Report in due time and form (10%). No dispensation allowed. Likewise, at the end of all the practices, a control online of all of them will be carried out (10%).
* Theoretical final exam multiple choice and/or conceptual (60%)
- DO NOT EXCEED the course students not submitted Final Exam or obtain a rating in this less than 3 points.
Neither the matter be overcome if not to exceed Practices, which requires at least the attendance at all Interactive Classes and delivery practices on time Memory Practices. Overcoming the practices will be forever.
- On a voluntary basis, the following will be valued: participation and attendance at Group Tutorials (first 2), preparation-presentation of a Monographic Work, and attendance at Waxing Practices (PE). At the end a control will be carried out on the summaries. The whole of everything will be valued (10%).
- Only students who have not made any measurable activity appear in ACTAS: Not presented (NP).
* FINAL GRADE: LECTURES (10 %) + PRACTICES (20 %) + SEMINARS-MW (10 %) + FINAL EXAM (60 %).
**The qualification of the "progressive evaluation" (Practices, Expository controls, Monographic works and Blackboard Practices) will be kept for the following courses.
For cases of fraudulent performance of exercises or tests, it will be applicable or established in the "Rules of assessment of academic performance of students and review of qualifications" (Article 16).
