N’,N”’-((1E,1’E)-(propane-1,3-diylbis (sulfanediyl)) bis (1-(4-bromophenyl) ethan-2- yl-1-ylidene)) bis (2-hydroxybenzohydrazide) (BAPSSHZ) is found to be a selective and sensitive analytical reagent for the determination of trace levels of nickel (II) in environmental samples like medicinal plant materials and water samples (potable and polluted) by spectro-photometry. BAPSSHZ reacts with Ni (II) at pH 5.0 in aqueous DMF to form a yellow-colored (Ni-BAPSSHZ) complex that shows maximum absorbance (λmax) at 343 nm. Immediate color reaction and the absorbance remain constant for about 48 h. The molar absorptivity coefficient and Sandell’s sensitivity are found to be 7.21×104 L.mol-1 cm-1 and 0.064 µg cm-2 of Ni(II), respectively. The system obeys Beer`s law in the range of 2.37-23.71 µg mL-1 of Ni (II). The linear regression coefficient is 0.9991, and the standard deviation is 0.01086. A large number of cations, anions, and complexing agents do not interfere in this method. The developed method is applied for the determination of Ni(II) in medicinal plant materials and water samples (potable and...

The present study aimed at analyzing the effects of PUFA in D-galactose treated Wistar albino male rats by determining leukocyte telomere length using real-time quantitative PCR, Il-6, and high sensitive C-RP levels estimation using ELISA. D-galactose is administered for 42 days orally (100 mg/kg), and on 43rd-day, blood is collected from tail vein and plasma is separated and subjected for IL-6 and high sensitive C-RP estimation using ELISA and determination of length of leukocyte telomere by real time qPCR. PUFA had no significant influence on length of leukocyte telomere and it decreased significantly IL-6 and high sensitive C-RP levels, indicating possible anti-aging effects by decreasing inflammation associated with aging...

Several behavioral addictions have been hypothesized as having similarities to substance abuse addictions. The DSM-4-TR has designated formal diagnostic criteria for several addictive disorders classifying them as impulse control disorders, a separate category from substance use disorder. There have been a lot of behavioral addiction studies like tanning, cosmetic surgery, sexual addiction, etc. Mobile phone addiction, which has more recently evolved into Smartphone addiction or nomophobia. The American Psychiatric Association first categorized a behavior: gambling as a no substance, related addictive disorder, and recommends further research on internet gaming disorder. The aim of this review is to find Smartphone addiction relations with neurotransmitters that could help us understand the possibly addictive effect similar to that produced by conventional drugs and also its potential to be diagnosed as an independent disorder. Multiple neurotransmitter systems are involved in the biochemistry of behavioral addictions; especially dopamine seems to be the most active. Brain activation in Internet gaming addicts occurs in the same brain regions as with drug-associated addiction. Brain imaging studies; suggest...

One of the essential scientific research concluded that DNA / RNA forms the hereditary or the genomic material in all life forms. The double-helical model given by Watson and Crick further added to the biological findings, and since then, various other DNA structures have been established viz., triple-stranded structures, quadruplexes, higher-order structures such as G-wires, polyads, etc. This review article takes into account the various aspects of the guanine rich called the G-quadruplex structure of the DNA, which are formed in the promoter region of a regulator gene called c-myc. Various ligands and proteins help in stabilizing/destabilizing the G-quadruplex structure present in the regulator gene, but a mutated version of the c-myc is seen during cancer, which leads to altered functions and expression of transcription protein leading to unregulated cell growth and proliferation. Thus, G-quadruplexes help in the regulation of the telomerase enzyme activity and can pave the way for the anticancer drugs, which are the need of the...

Introduction: Vernonia arborea, belonging to the Asteraceae family, found in the Western Ghats of India and Sri Lanka, was traditionally used in wound healing. It is proven that some of the plants of this genus have anti-diabetic properties. e.g., V. amygdalina. So this study was done to screen and to evaluate the anti-diabetic potency of the leaf extract of Vernonia arborea in diabetic Zebrafish models. Materials and Methods: Extraction was done by cold percolation method. The toxicity of the extract was evaluated, and the concentrations of 25 mg/l and 50 mg/l of tank water were taken for treatment as higher concentrations were found to be toxic. The Zefrafish were divided into the respective control and treatment groups. The different groups were induced with diabetes by high-glucose feed for 30 days. The standard group was treated with metformin and the test groups with the chosen concentrations of the extract for 7 days. The blood glucose level was checked on alternate days for 7 days. On the 7th day, the liver...
