Abstract

Abstract Cognitive deficits are long-lasting consequences of drug use, yet the convergent mechanism by which classes of drugs with different pharmacological properties cause similar deficits is unclear. We find that both phencyclidine and methamphetamine, despite differing in their targets in the brain, cause the same glutamatergic neurons in the medial prefrontal cortex of male mice to gain a GABAergic phenotype and decrease expression of their glutamatergic phenotype. Suppressing drug-induced gain of GABA with RNA-interference prevents appearance of memory deficits. Stimulation of dopaminergic neurons in the ventral tegmental area is necessary and sufficient to produce this gain of GABA. Drug-induced prefrontal hyperactivity drives this change in transmitter identity. Returning prefrontal activity to baseline, chemogenetically or with clozapine, reverses the change in transmitter phenotype and rescues the associated memory deficits. This work reveals a shared and reversible mechanism that regulates the appearance of cognitive deficits upon exposure to different drugs.

Abstract

Postoperative pain is acute with complex physiological responses to tissue injury. Epidural technique using opioids has been found to provide better pain relief than systemic opioids and also decreased incidence of postoperative complications. AIMS AND OBJECTIVES The aim of this study was to compare the onset, duration, quality of analgesia, cardio-respiratory effects and side effects of epidural butorphanol with epidural fentanyl for the relief of postoperative pain. METHODOLOGY 60 patients of either sex, age group of 18- 60 years, belonging to ASA grade Ι and ΙΙ, posted for elective lower abdominal surgeries were selected. They were randomly divided into 2 groups of 30 each. All surgeries were done under lumbar epidural anaesthesia. Postoperatively, when patient complained of pain, intensity of pain was assessed using Linear Visual analog scale (VAS) and when VAS score was >5, patients received either epidural butorphanol 2mg or epidural fentanyl 100µg diluted to 10ml with normal saline. Onset of analgesia, which is the time interval from administration of study drug till VAS score came down to < 5 was noted in both groups. Duration of analgesia, which is the time interval between start of analgesia (VAS score < 5) till patient complaints of pain (VAS score >5) was noted in both groups. Quality of analgesia was assessed using pain score in both the groups. Cardio-respiratory effects, heart rate, blood pressure and respiratory rate were monitored at regular intervals and were compared between the 2 groups. Side effects like sedation, pruritus, nausea, vomiting, hypotension and respiratory depression were noted. RESULTS Demographic profile (age, sex) was comparable in both groups. The onset of analgesia was clinically and statistically significantly late (6minutes) in butorphanol group when compared to fentanyl group (3minutes). Duration of analgesia was longer in butorphanol group (350 minutes) in comparison to fentanyl group (230 minutes) which was clinically and statistically significant. Quality of analgesia was better in butorphanol group. Sedation was the main side effect in butorphanol group. Incidence of pruritus, vomiting, hypotension and respiratory depression was more in fentanyl group. CONCLUSION Epidural butorphanol provides delayed onset but longer duration and better quality of analgesia than fentanyl with paucity of clinically significant side effects with both groups.

Abstract

To travel securely on roads, traffic signs are very important. The main cause of road accidents is laxity in viewing the traffic signboards and analysing them wrongly. To avoid all these problems, the new system is implemented. This system helps in identifying the traffic sign and sends a voice command to the driver, so that the driver will take necessary actions to travel safely. The system is trained by using Convolutional Neural Network (CNN/ConvNet), helps in classification and recognisation of traffic sign images. To make the system more accurate, a particular dataset is taken and trained by defining a set of classes. The German Traffic Sign Recognition Benchmark dataset was used for classification of sign boards,it contains more than 40 classes and more than 50000 images of traffic signs. After detecting the sign, a voice command is sent to notify the driver and aware him/her to follow the necessary rules on the road. The main aim of this system is safe and secure travelling and the lives of the people. [ABSTRACT FROM AUTHOR]
