Randomised Control Study Comparing the Haemodynamic Changes to Intubation using Levitan Optical Stylet alone Versus Intubation using Levitan Optical Stylet along with Macintosh Laryngoscope
No full textEndotracheal intubation and laryngoscopy are very essential tools in the hands of anaesthesiologist in maintaining airway. Airway management is the fundamental aspect of anaesthetic practice, emergency and critical care medicine. Endotracheal intubation incur haemodynamic responses like increase in heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure. Since the upper airway is highly innervated, airway instrumentation results in significant haemodynamic responses.
Anaesthesiologist found a technique of intubation which minimized the stimulation of the upper airway. Levitan optical stylet gained its importance, since its introduction by Dr. Richard Levitan. The shorter length resembles standard stylet making it useful in every laryngoscopy, handling and shaping of the tracheal tubewhile offering a fibreoptic intubation and immediate visual confirmation of intratracheal placement. The primary objective of this study was to compare the haemodynamic responses to intubation using Levitan optical stylet alone versus intubation using levitan optical stylet along with Macintosh laryngoscope. Secondary outcome measures the ease of intubation, intubation time with two techniques, complications and failure rate. We recruited 80 patients in this prospective study, after obtaining ethical committee approval. These patients were aged between 18-60 yrs belonging to ASA I and ASA II with MPC I and MPC II and thyromental distance >6.5 cm. Hypertensive patients, difficult airway and cardiovascular patients were excluded from the study. They were divided into two groups. Group A – intubation carried with Levitan optical stylet, Group B - intubation carried out with Levitan optical stylet along with Macintosh laryngoscope. These patients were evaluated for the haemodynamic responses at preintubation, postintubation (0min), 1min, 3min, 5min and 10 min respectively. The time taken for intubation, ease of intubation in both the groups were also noted down.
Postoperatively patients were monitored for complications such as sorethroat, hoarseness of voice and bleeding. These results were tabulated and analysed using SPSS software version 22. The two groups were comparable in terms of age, weight and sex. Other parameters such as ASA, thyromental distance, interincisor gap were also comparable. The stress response associated with endotracheal intubation was more with group B (patients intubated with Macintosh laryngoscope) than with group A (intubation with Levitan alone) at post intubation 0min,1min and 3 min as the p valve was 0.00. The mean time taken for intubation in group A (55 seconds) was longer than group B (20 seconds) and the p value was 0.00 and found to be statistically significant. The success rate of intubation in group B was 100% whereas in group A was 95%. The failure rate of intubation was 5% in group A. No serious complications were encountered in both the groups. Hence we concluded that Levitan optical stylet was more superior than conventional Macintosh laryngoscope in the aspect of haemodynamic responses
An RNA interference knock-down of nitrate reductase enhances lipid biosynthesis in the diatom Phaeodactylum tricornutum
No full textWhen diatoms are stressed for inorganic nitrogen they remodel their intermediate metabolism and redirect carbon towards lipid biosynthesis. However, this response comes at a significant cost reflected in decreased photosynthetic energy conversion efficiency and growth. Here we explore a molecular genetics approach to restrict the assimilation of inorganic nitrogen by knocking down nitrate reductase (NR). The transformant strain, NR21, exhibited about 50% lower expression and activity of the enzyme but simultaneously accumulated over 40% more fatty acids. However, in contrast to nitrogen-stressed wild-type (WT) cells, which grow at about 20% of the rate of nitrogen-replete cells, growth of NR21 was only reduced by about 30%. Biophysical analyses revealed that the photosynthetic energy conversion efficiency of photosystem II was unaffected in NR21; nevertheless, the plastoquinone pool was reduced by 50% at the optimal growth irradiance while in the WT it was over 90% oxidized. Further analyses reveal a 12-fold increase in the glutamate/glutamine ratio and an increase NADPH and malonyl-CoA pool size. Transcriptomic analyses indicate that the knock down resulted in changes in the expression of genes for lipid biosynthesis, as well as the expression of specific transcription factors. Based on these observations, we hypothesize that the allocation of carbon and reductants in diatoms is controlled by a feedback mechanism between intermediate metabolites, the redox state of the plastid and the expression and binding of transcription factors related to stress responses.Peer reviewe
Landscape Painting in Russian Fine Art after Levitan. The Ivanovo Region in Painting: A Century’s Experience
No full textThe article discusses the issues of regional art schools and the place of landscape in the modern classification of genres in art based on the material of the intermuseum exhibition project The Ivanovo Region in Painting. The 20th-21st Centuries, conceived and implemented in Ivanovo in 2024. The author indicates the stages of formation and development of the landscape genre in Russian painting up to the 20th century, finding some parallels with the history of landscape painting in English art. The project of the Ivanovo museum community, where more than 60 works of landscape painting were presented, leads the author to the conclusion that after I.I. Levitan, for over a century, the Volga motifs have given an impulse of inspiration to subsequent generations of artists of the Ivanovo Region. In their works, they created artistic images of the cities of the region, such as Yuryevets, Palekh, Plyos, Kineshma, and Shuya, which have gone beyond mere geographical names and become landmarks on the cultural map of Russia, symbolizing “Russianness”, Russian landscape, and the Russian soul. In the author’s opinion the exhibition project is a vivid evidence of the existence of an independent regional art school of landscape painting. It is argued that landscape, along with historical painting, assumes particular importance among all other genres, especially in times of social crises associated with the danger of the loss of national identity

A proof of first-order stochastic dominance for quantity constrained oligopolies
No full textIn this paper a proof for First Order Stochastic Dominance for capacity constrained oligopolies exhibiting equilibrium in mixed strategies is derived. The result is an extension of Levitan and Shubik (1972) where they derive the mixed strategy equilibrium for quantity constrained oligopolies. I show that their result has applications in policy issues in Regulation and Trade Theory. The proof of First Order Stochastic Dominance facilitates the comparison of expected prices across different experimental/trade policy designs, enlarging the qualitative implications of the results derived by Levitan et al
Obesity comorbidity in unipopular major depressive disorder: refining the core phenotype
No full textObjective: While a significant body of research has demonstrated high comorbidity rates between depression and obesity, the vast majority of this work has considered depression as a unitary diagnosis. Given that increased appetite and weight gain are highly characteristic of the “atypical” subtype of depression, while classic depression is characterized by decreased appetite and weight loss, it would be important to examine whether increased obesity risk is consistent across the major vegetative subtypes of depression or is limited to the atypical subtype.Method: Using data from the 2001–2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), we identified 5,092 US adults with past or current major depression based on DSM-IV-TR criteria and 1,500 gender-matched controls. Each depressed subject was designated as having classic, atypical, or undifferentiated depression based on core vegetative symptoms. Logistic regression models examined rates of current obesity (defined as a current body mass index [kg/m2] > 30) across the 3 depressive subgroups and nondepressed controls, adjusting for demographic differences. To limit the possible effect of current depressive symptoms on observed obesity rates, secondary analyses were completed in individuals with past depression only.Results: Subjects with atypical depression had markedly elevated obesity rates compared to population controls and to other depressed subjects, with corresponding pairwise odds ratios consistently greater than 2.0 (P < .001). In contrast, obesity rates were not significantly different in subjects with classic depression and nondepressed controls. These results were manifest in individuals with either current or past depression and were independent of gender and age.Conclusions: While many individuals with classic depression will present with obesity due to the high prevalence of both disorders, only atypical depression is associated with an elevated risk of obesity relative to the population at large. Refining the target phenotype(s) for future work on depression and obesity might improve our understanding, prevention, and treatment of this complex clinical problem
