Antidepressant effects of coumarins and their derivatives: A critical analysis of research advances
No full textCoumarins and their derivatives are non-flavonoids polyphenols with diverse pharmacological activities
including anti-depressant effects. This study systematically examines the antidepressant effects of coumarins and
their derivatives in relation to time series of research progress in the pharmacological pathways, association with
other diseases, toxicity and bibliometric analysis. The review was approached using the Preferred Reporting
Items for Systematic Reviews and Meta-Analyses (PRISMA) coupled with R package involving Biblioshiny, a web
interface for Bibliometrix analysis and VOSviewer software analytic tools. Literature searches were conducted in
Scopus, Web of Science, and PubMed from the inception through January 21, 2023. Coumarins, depression,
coumarin derivatives and treatment were the main search terms used which resulted in the inclusion of 46
eligible publications. Scopoletin, psoralen, 7-hydroxycoumarin, meranzin hydrate, osthole, esculetin/umbelli
ferone were the most studied coumarins with antidepressant effects. Coumarins and their derivatives exerted
antidepressant effects with a stronger affinity for monoamine oxidase-B (MAO-B) inhibition and, their inhibitory
effect via neurotransmitter pathway on MAO is well-studied. However, epigenetic modification, neuroendocrine,
neurotrophic pathways are understudied. Recent research focuses on their antidepressant effects which targeted
cytokines and fibromyalgia. There is a link between the gut microbiome, the brain, and depression; meranzin
hydrate exerts an antidepressant activity by remodelling the gastrointestinal system. We established that
empirical data on some coumarins and their derivatives to support their antidepressant effects are limited.
Likewise, the safe dose range for several coumarins and their derivatives is yet to be fully determined
Dynamical phase diagrams of a love capacity constrained prey–predator model
No full textOne interesting question in love relationships is: finally, what and when is the end of this love relationship? Using a prey–predator Verhulst–Lotka–Volterra (VLV) model we imply cooperation and competition tendency between people in order to describe a “love dilemma game”. We select the most simple but immediately most complex case for studying the set of nonlinear differential equations, i.e. that implying three persons, being at the same time prey and predator. We describe four different scenarios in such a love game containing either a one-way love or a love triangle. Our results show that it is hard to love more than one person simultaneously. Moreover, to love several people simultaneously is an unstable state. We find some condition in which persons tend to have a friendly relationship and love someone in spite of their antagonistic interaction. We demonstrate the dynamics by displaying flow diagrams.Fil: Simin, P. Toranj. Shahid Beheshti University; IránFil: Jafari, Gholam Reza. Shahid Beheshti University; Irán.

Evaluation of Plasma Beta-2-microglobulin in Patients with the Nephrotic Syndrome
No full textIn patients with the nephrotic syndrome, it is often desirable to assess the disease process, not only by proteinuria but also by indices of glomerular inflammatory process. We investigated the importance of β-microglobulin (βM) as a means of assessing renal function in patients with the nephrotic syndrome with normal or abnormal values of creatinine clearance. There were 46 patients (mean age, 42.2 + 10.4 years; male/female (M/F) ratio = 31/15) and 35 healthy controls (mean age 39 + 4.5 years, M/F ratio 25/10). We subdivided the study patients into group A (n = 18, mean age 39.6 + 10.6 years, M/F ratio 8/10) and group B patients (n = 28, mean age 45.6 + 8.9 years, M/F ratio 23/5) who had normal and abnormal values of creatinine clearance respectively. An enzyme-linked-immunosorbent assay (ELISA) was used to quantitate plasma β2M in the study patients and controls. The median 132M levels of the study patients and controls were 44.0 and 1.7 mg/l respectively (p < 0.0001). Beta-2-M levels correlated significantly with serum creatinine (r = 0.56, p < 0.0001), and creatinine clearance (r = -0.6, p < 0.0001). In group A patients, the median β2M level was significantly higher than normal (4.1 vs. 1.7 mg/1, p < 0.01). Plasma β2M levels did not correlate well with any other parameter measured in group A patients. When groups A and B were compared, the median plasma β2M level in group B was significantly higher than group A (20.3 vs. 4.1 mg/1, p < 0.0001). The urinary β2M (expressed per mg urine creatinine) was also higher in group B than group A patients (6.8 vs. 0.7 p < 0.05). We conclude that elevation of β2M-microglobulin in patients with the nephrotic syndrome who have normal creatinine clearance suggests early abnormal renal function in these patients. It may be used to assess the rate of normalisation of renal function or progression to chronic renal failure
Synthesis, characterization and antimicrobial studies of organotin(IV) complexes of N-methyl-N-phenyldithiocarbamate
No full textOrganotin(IV) dithiocarbamate complexes have shown a large spectrum of biological activities, which includes antioxidants, anti-inflammatory, antimicrobial, antituberculosis, anticancer and antiviral. In this report, organotin(IV) dithiocarbamate complexes derived from N-methyl-N-phenyldithiocarbamate (L) and organotin have been synthesized. The complexes which were represented as C4H9(Cl)SnL2 (1), C6H5(Cl)SnL2 (2), (CH3)2SnL2 (3), (C4H9)2SnL2 (4) and (C6H5)2SnL2 (5), were characterized by spectroscopic techniques (FTIR, 1H, 13C and 119Sn NMR), elemental and thermal analyses (TGA and DTG). The structures of complexes (3) and (4) were further established by X-ray single crystal diffraction. The structures, in both complexes, gave a distorted octahedral geometry around the tin center. This is due to the longer bond length of one of the SnS bonds within the complexes compared to others, and also the electronic and steric demands caused by the alkyl substituents on the tin atom. The complexes exhibited varied antimicrobial activity against S. Aureus, B. cerues, K. pneumonia, P. aeruginosa, E. coli, C. albican and A. flavus. Complex 5 displayed the best antimicrobial activities compared to the other organotin complexes, and this could be attributed to the planar phenyl group attached to the tin center causing an increase in the lipophilicity of the complex through the lipid bilayer of the bacteria organism
Columnar Radio Refractivity Of The Troposphere At Ashodi And Kano
No full textSpatial-temporal, distributions of columnar radio refractive index in the troposphere of two tropical stations – Kano and Oshodi are considered. Monthly means of radio refractivity have been shown for the atmospheric columns, 0 – 3km (the lower atmosphere), 0- 10km (the first 10km column), and 3-10km (the upper atmospheric column). Correlation coefficient between monthly means of surface radio refractivity Ns and refractivity at each of the atmospheric columns NL, NT and Nu (refractivity values for 0-3km, 0-10km, 3-10km respectively) is higher than 0.9 at Kano and 0.7 at Oshodi in most of the cases. Equations of regression have also been obtained by means of which measurements of Ns can be used to estimate the refractivity gradient δN of the first one kilometer over each of the two stations and other places in the same climate zone.
