Caffeine and Activation Theory: Effects on Health and Behaviors
(CRC Press, 2006) Barry D. Smith; Uma Gupta; B.S. Gupta
The virtually universal popularity of caffeine, together with concerns about its potential pathogenic effects, have made it one of the most extensively studied drugs in history. However, despite the massive scientific literature on this important substance, most reviews have either focused on limited areas of study or been produced in popular form by individuals with surprisingly little relevant scientific background. Caffeine and Activation Theory: Effects on Health and Behavior brings together the leading experts from seven different countries to provide researchers and clinicians with the most comprehensive and balanced review of the scientific literature on the effects of caffeine found anywhere. It devotes unprecedented coverage to the impact of caffeine on cardiovascular functioning and pathology, details the pharmacological properties and neurophysiological effects of the drug, and thoroughly reviews literature concerned with the role of this powerful stimulant in mood, task performance, and psychopathology. This important new book is also the first source to provide an integrative scientific treatment of the effects of caffeine consumption on menstrual endocrinology and pathology, as well as on reproduction. Rounding out the coverage is a thorough review of emerging research on the possible benefits of caffeine and catechins in green and black teas. The highly integrative final chapter provides a clear understanding of what is known about the effects of caffeine, identifies specific areas in which further research is needed, and provides important methodological guidelines that promise to optimize future research endeavors. Filling the need for a current comprehensive resource, this volume provides extensive reviews of the major bodies of literature on caffeine, stimulates and guides future research, and provides clinicians with the information they need to understand, diagnose, and treat the effects of caffeine consumption in their pati © 2007 by Taylor & Francis Group, LLC.

Caffeine differentially affects kinesthetic aftereffect in high and low impulsives
(Springer-Verlag, 1990) Uma Gupta; B.S. Gupta
The effects of caffeine on kinesthetic aftereffect (KAE) were examined. Following a between-subjects design, high and low impulsive male postgraduate students were administered placebo and four doses of caffeine (1, 2, 3 and 4 mg/kg body weight) in a laboratory situation. A double blind procedure was adopted for drug administration. The study supports the following conclusions: (1) caffeine reduces KAE in high impulsive subjects; (2) the larger dose of caffeine (4 mg/kg) enhances KAE in low impulsive subjects; (3) caffeine produces profound effects on the performance of high impulsives; (4) caffeine leads to different dose-response trends in the two groups. © 1990 Springer-Verlag.
Caffeine, impulsivity, and performance
(Taylor and Francis, 2020) Uma Gupta; B.S. Gupta
The behavioral effects of caffeine, a widely consumed 1-3 substance and a recognized potent stimulant, 4-6 have been studied extensively for a variety of reasons 7: (1) it is readily available (2) it is generally recognized as safe; (3) it has a rapid onset of action; and (4) it is active when taken orally. However, the major disadvantage is that when administered in doses generally found in foods and drinks, its effects are slight, subtle, and almost negligible. 7. © 1999 by Taylor & Francis Group, LLC.

Differential effects of caffeine on free recall after semantic and rhyming tasks in high and low impulsives
(Springer-Verlag, 1991) Uma Gupta
The effects of caffeine on free recall after acquisition on semantic and rhyming tasks were examined. Following a between-subjects design, high and low impulsive male postgraduate students were administered placebo and four doses of caffeine citrate (1, 2, 3 and 4 mg/kg body weight) in a laboratory situation. A double blind procedure was adopted for drug administration. The study supports the following conclusions: (1) under no drug condition, high impulsives recall more after semantic acquisition while their counterparts, the low impulsives, recall more after rhyming acquisition; (2) caffeine facilitates recall in high impulsives after rhyming acquisition but hinders it after semantic acquisition; (3) caffeine does not reliably influence recall of low impulsives. © 1991 Springer-Verlag.
Effects of caffeine on perceptual judgment
(1994) Uma Gupta; G.P. Dubey; B.S. Gupta
The present study examined the effects of caffeine on the estimation of felt width of blocks employing haptic presentation. Following a between-subject design, 160 male postgraduate students classified as high or low impulsives received either placebo or one of four doses of caffeine citrate (1, 2, 3 and 4 mg/kg body weight). A double-blind procedure was adopted for drug administration. Caffeine produced differential effects on the performance of high and low impulsives, facilitated performance (decreased error in perceptual judgment) in high impulsives but had no influence on the performance of low impulsives. The dose-response trends also followed different patterns in the two groups of subjects. © 1994 S. Karger AG, Basel.
Effects of caffeine on recognition
(1993) Uma Gupta
The present study examined the effects of caffeine on recognition performance after acquisition of conceptual and acoustic tasks. Following a between-subject design, 300 male postgraduate students classified as high or low impulsives received either placebo or one of four doses of caffeine citrate (1,2,3, and 4 mg/kg body weight). A double-blind procedure was adopted for drug administration. Caffeine facilitated recognition performance after acoustic acquisition but impaired it after conceptual acquisition in high impulsives. The drug had no influence on recognition performance of low impulsives. © 1993.
Overexpression of miR166 in Response to Root Rhizobacteria Enhances Drought Adaptive Efficacy by Targeting HD-ZIP III Family Genes in Chickpea
(Springer Science and Business Media Deutschland GmbH, 2024) Ankita Yadav; Sanoj Kumar; Rita Verma; Shiv Narayan; Uma Gupta; Charu Lata; Shashi Pandey Rai; Indraneel Sanyal
Using the transgenic approach, the current study investigated the tripartite interaction of miRNA166, Plant Growth Promoting Rhizobacteria (PGPR), and chickpea crops in response to drought. miR166, an evolutionarily conserved small RNA, was cloned and transformed in a homologous manner. This Car-miR166 is reported in our previous research to have drought-enduring roles in response to microbial candidates. A Pseudomonas putida strain RA (MTCC5279) is used as a PGPR for the whole study. The overexpressed lines generated using tissue-culture practice were functionally validated with physiological parameters studied using Li-Cor 6400XT, including photosynthesis rate, transpiration rate, water-use efficiency, and electron transport rate. We also studied the relative water content of the overexpressed lines in comparison to treated control plants. In biochemical methods, we studied the accumulation of proline, superoxide dismutase, peroxidase, catalase, H2O2 and lipid peroxidation levels. miR166 has its target as ATHB15 (Homeobox-leucine zipper protein-15) validated using 5’ RNA Ligase-Mediated Rapid Amplification of cDNA Ends (RLM-RACE) experiment. At the molecular levels, we carried out the stem-loop quantitative real-time (qRT) PCR analysis of miR166 and the expression analysis of ATHB15 in transgenic lines. As per our study, the results reported that the transgenic lines showed a positive interaction of miR166 with PGPR, resulting in drought stress mitigation and better plant survival in harsh drought conditions. In conclusion, the physiology, biochemistry, and molecular expression levels of Car-miR166 (Cicer arietinum L.) in transgenic lines in response to PGPR support enhanced growth and development in response to PGPR in transgenic lines under drought. © The Author(s) under exclusive licence to Sociedad Chilena de la Ciencia del Suelo 2024.

Psychophysiological reactions to music in male coronary patients and healthy controls
(SAGE Publications Ltd, 2015) Uma Gupta; B.S. Gupta
The study aimed to present a comparative account of psychophysiological responses to music-listening in male coronary patients and healthy controls. The stimulus material was a slow-paced, taped ra¯ga Desi-Todi played on a flute. The participants listened to music for 30 minutes a day for 20 days. Pre- and post-treatment procedure was adopted for assessment on psychophysiological measures. The study supports the following conclusions: (1) music-listening produces significant decreases in the blood pressure (both systolic and diastolic) and heart rate of coronary patients but has no significant effect in healthy controls; (2) music-listening reduces stress, anxiety, and depression, enhances life satisfaction, optimism and hope, and makes life more meaningful in both coronary patients and healthy controls; (3) the effects of music listening, that is, reduction in negative affect, enhancement of positive affect, and decrease in blood pressure and heart rate, are more intense in coronary patients than healthy controls. © Society for Education, Music, and Psychology Research.
Psychophysiological responsivity to Indian instrumental music
(SAGE Publications Ltd, 2005) Uma Gupta; B.S. Gupta
The effects of rāga Desi-Todi played on a flute by a renowned Indian musician, Hari Prasad Chaurasia, were examined on three physiological (alpha EEG frequency, systolic and diastolic blood pressure and heart rate) and three psychological (depression, state and trait anxiety, and four components of anxiety: somatic, cognitive, behavioral and affective) assessments. The postgraduate male university students served as subjects. The subjects listened to instrumental music (without lyrics) for 30 minutes a day for 20 days. A pre- and post-treatment procedure was adopted for recording physiological and psychological assessments. The results showed that the instrumental music led to a significant increase in the alpha EEG frequency and a significant decrease in the scores on depression, state and trait anxiety, and the four components of anxiety; the systolic and diastolic blood pressure and heart rate, however, remained unaffected.
