Review on Image Inpainting using Intelligence Mining Techniques

Objective Inpainting is a technique for fixing or removing undesired areas of an image. Methods In present scenario, image plays a vital role in every aspect such as business images, satellite images, and medical images and so on. Results and Conclusion This paper presents a comprehensive review of past traditional image inpainting methods and the present state-of-the-art deep learning methods and also detailed the strengths and weaknesses of each to provide new insights in the field

Effect of an extract of Centella asiatica on the biodistribution of sodium pertechnetate (Na^99mTcO₄) and on the fixation of radioactivity on blood constituents

This study evaluates the effects of an acute treatment with a Centella asiatica (CA) extract on the biodistribution of the radiopharmaceutical Na99mTcO4 and on the fixation of technetium-99m on blood constituents. Wistar rats were treated with CA extract and, 1 hour after, Na99mTcO4 was administered; organs/tissues were withdrawn and weighted. The radioactivity was counted to calculate the percentage of activity per gram (%ATI/g). Also, blood samples were withdrawn, plasma (P), blood cells (BC), insoluble fraction (IF) and soluble fractions of P and BC were isolated and the radioactivity was counted to calculate the percentage of activity (%ATI). Data indicated that the acute treatment with CA extract changed significantly (p99mTcO4 and the fixation of the technetium-99m on blood constituents in an acute treatment

Emergence and spread of two SARS-CoV-2 variants of interest in Nigeria.

Identifying the dissemination patterns and impacts of a virus of economic or health importance during a pandemic is crucial, as it informs the public on policies for containment in order to reduce the spread of the virus. In this study, we integrated genomic and travel data to investigate the emergence and spread of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants of interest in Nigeria and the wider Africa region. By integrating travel data and phylogeographic reconstructions, we find that these two variants that arose during the second wave in Nigeria emerged from within Africa, with the B.1.525 from Nigeria, and then spread to other parts of the world. Data from this study show how regional connectivity of Nigeria drove the spread of these variants of interest to surrounding countries and those connected by air-traffic. Our findings demonstrate the power of genomic analysis when combined with mobility and epidemiological data to identify the drivers of transmission, as bidirectional transmission within and between African nations are grossly underestimated as seen in our import risk index estimates

Betaine reverses toxic effects of aluminium: Implications in Alzheimer's disease (AD) and AD-like pathology

Impairment in T-maze erformance of aduIt rats P, caused by altminiurn $(A1^{3+})$ and the reversal of it by betaine, a methyl donor, was studied. Besides, conformational change in the secondary structure of $\beta$ amloid peptide $(A\beta)$ brought about by the addition of $(A1^{3+})$ in vitro, was also studied using CD-spectroscopy. The organisrnal study proved that betaine is effective in restoring the memory loss caused by $(A1^{3+})$ possibly through augmentation of choline leveIs, as betaine is involved in the synthesis of choline. The CD-spectra recorded indicate loss of $\alpha$ -helical content of the peptide $(A\beta)$ caused by the addition of $(A1^{3+})$ , which was reversed to some extent by the addition of betaine. Betaine may thus preventlstop the progression of plaque formation seen during the initial stages of Alzheimer's disease (AD), and AD-like pathology as the loss of secondary structure of $A\beta$ is suspected to be an early event in the aetiopathology of ADIAD-like perturbations caused by Al toxicity. Betaine, a natural product occurring in beetroot (Beta vulgaris), and a by product in the process of manufacturing beet sugar may thus prove efficacious in the treatment of diseases involving dysfunctions of cholinergic system leading to memory loss
