Filter by:Background: Multiple studies have pointed to the harmful potential of licit and illicit drugs. as agents associated with neoplastic processes and other non-communicable diseases, for which reason It has become a problem of global size. Objective: The central objective is to determine the cytogenotoxic damage in the oral mucosa of people with chronic drug use, as well as establishing the therapeutic effect of acid administration folic on said damage. Methodology: Quasi-experimental study, pretest-posttest design with no control group. equivalent, in subjects with substance abuse and healthy subjects. The intervention will consist of administration of 15 mg of folic acid divided into 3 doses per day. Mucosal samples will be taken orally in duplicate to each participant to determine the frequency of micronuclei (MN), bursts cells (NBUD), binucleated cells (BN), condensed chromatin (CC), karyorrhexis (CR), pyknosis (PIC) and caryolysis (CL) at different time events: pre-treatment, 15 days and 30 days. So as a survey to determine consumption patterns of psychoactives, sociodemographic data, dietary and exposure to known cytogenotoxic agents. Resources and infrastructure: The study will be carried out in the pharmacology laboratory of the Center University of Tonalá, who will make their equipment and reagents available. Group experience: The research group has over a decade of experience in the development of projects related to mutagenesis and cyto-genotoxic agents. Development time: The project will be developed from February 2023 to August of 2023
The purpose of this study is to determine the pharmacokinetics and pharmacodynamics of oral delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) and to evaluate detection of recently smoked THC in oral fluid.
Background: Alcohol Use Disorder (AUD) is a complex psychiatric disorder, involving several brain areas and neurocircuits. Transcranial Direct Current Stimulation (tDCS) allows to stimulate superficial areas of brain using a weak electrical current. Preliminary data suggest that tDCS may reduce alcohol craving and consumption. Objectives: The main outcome is to test if tDCS can reduce alcohol craving and use and to assess the changes in BDNF and pro-BDNF levels. Secondary outcomes are the assessment of other psychiatric dimensions (mood, behavioral and cognitive alterations) associated with prolonged alcohol use. Eligibility: Healthy, right-handed adults ages 18-65 who do have AUD (moderate to severe). Design: This is a randomized, double-blind, sham-controlled study with three phases: 1) a tDCS intensive treatment phase; 2) follow-up with weekly tDCS stimulation; 3) follow-up without tDCS stimulation. Participants will be screened with: - Psychometric Scales - Medical history - Physical exam - Urine tests and breathalyzer - After being enrolled, baseline behavioral and laboratory data will be collected. In particular, participants will undergo: - Psychometric Scales - Venous blood sample (BDNF/proBDNF levels) Participants will be randomized to real or sham tDCS arm. The stimulation will be delivered daily for five days during the first week (intensive treatment phase) and then weekly for 3 months (follow-up with stimulation). During this period patient will be tested with a behavioral and psychometric evaluation.Therefore, participants will receive 3 follow-up monthly visits without tDCS stimulation, in which behavioral and psychometric data will be collected. Treatment includes: - tDCS: The tDCS will be delivered with a stimulator connected to two sponge electrodes, soaked in a saline solution. The stimulation will be administered at a current intensity of approximately 1 mA, for the duration of 20 minutes. The anode will be placed on the right DLPFC, the cathode on the contralateral cortical area. - BDNF/proBDNF levels: A venous blood sample will be collected before the first stimulation and after the last stimulation of the intensive-stimulation period (first week). The blood sample will be centrifuged within 20 minutes of sampling at 1000 × g for 15 minutes. Then, the serum will be aliquoted and stored at -80 ° C until analysis. - Repeat of screening tests and questionnaires - Urine toxicological screen and breathalyzer
