Channel encoding system for transmitting image over wireless network

Various encoding schemes have been introduced till date focusing on an effective image transmission scheme in presence of error-prone artifacts in wireless communication channel. Review of existing schemes of channel encoding systems infer that they are mostly inclined on compression scheme and less over problems of superior retention of signal retention as they lacks an essential consideration of network states. Therefore, the proposed manuscript introduces a cost effective lossless encoding scheme which ensures resilient transmission of different forms of images. Adopting an analytical research methodology, the modeling has been carried out to ensure that a novel series of encoding operation be performed over an image followed by an effective indexing mechanism. The study outcome confirms that proposed system outshines existing encoding schemes in every respect

Antiangiogenic effects of butyric acid involve inhibition of VEGF/KDR gene expression and endothelial cell proliferation

The formation of new blood vessels from pre-existing ones is required for the growth of solid tumors and for metastasis. Interaction of tumor-secreted vascular endothelial growth factor (VEGF) with its receptor(s) on endothelial cells triggers endothelial cell proliferation and migration, which facilitate tumor angiogenesis. Butyric acid (BuA), a fermentation product of dietary fibers in the colon, is shown to alter gene expression and is postulated to be anticarcinogenic. The results presented in this paper indicate that BuA can be antiangiogenic in vivo by inhibiting angiogenesis in chorioallantoic membrane assay. BuA was not cytotoxic to endothelial cells but was a potent antiproliferative agent besides being proapoptotic to endothelial cells as verified by FACS analysis. Conditioned media from BuA-treated Ehrlich ascites tumor cells showed a 30% decrease in VEGF concentration when compared with untreated cells. The decrease in VEGF mRNA and its receptor, KDR mRNA levels in EAT and endothelial cells respectively, suggests that the VEGF-KDR system of angiogenesis is the molecular target for the antiangiogenic action of BuA

Molecular mechanisms of anti-angiogenic effect of curcumin

Modulation of pathological angiogenesis by curcumin (diferuloylmethane), the active principle of turmeric, seems to be an important possibility meriting mechanistic investigations. In this report, we have studied the effect of curcumin on the growth of Ehrlich ascites tumor cells and endothelial cells in vitro. Further, regulation of tumor angiogenesis by modulation of angiogenic ligands and their receptor gene expression in tumor and endothelial cells, respectively, by curcumin was investigated. Curcumin, when injected intraperitoneally (i.p) into mice, effectively decreased the formation of ascites fluid by 66 in EAT bearing mice in vivo. Reduction in the number of EAT cells and human umbelical vein endothelial cells (HUVECs) in vitro by curcumin, without being cytotoxic to these cells, is attributed to induction of apoptosis by curcumin, as is evident by an increase in cells with fractional DNA content seen in our results on FACS analysis. However, curcumin had no effect on the growth of NIH3T3 cells. Curcumin proved to be a potent angioinhibitory compound, as demonstrated by inhibition of angiogenesis in two in vivo angiogenesis assay systems, viz. peritoneal angiogenesis and chorioallantoic membrane assay. The angioinhibitory effect of curcumin in vivo was corroborated by the results on down-regulation of the expression of proangiogenic genes, in EAT, NIH3T3, and endothelial cells by curcumin. Our results on Northern blot analysis clearly indicated a time-dependent (0–24h) inhibition by curcumin of VEGF, angiopoietin 1 and 2 gene expression in EAT cells, VEGF and angiopoietin 1 gene expression in NIH3T3 cells, and KDR gene expression in HUVECs. Further, decreased VEGF levels in conditioned media from cells treated with various doses of curcumin (1μM–1mM) for various time periods (0–24h) confirm its angioinhibitory action at the level of gene expression. Because of its non-toxic nature, curcumin could be further developed to treat chronic diseases that are associated with extensive neovascularization

Artificial intelligence–based neural network for the diagnosis of diabetes and COVID: ANN model with optimum predictor variable

In many nations, the prevalence of diabetes is rising, and its impact on national health cannot be overlooked. Smart medicine is a medical concept in which technology is used to aid in disease detection and treatment. The objective of this study is to take a gander at the information and look at changed diabetic mellitus forecasting algorithms. According to rising dismalness as of late, the quantity of diabetic patients worldwide will arrive at 642 million out of 2040, suggesting that one out of each 10persons would be affected. This worrisome figure, without a question, demands immediate attention. AI has been applied to an assortment of aspects of clinical wellbeing as a result of its rapid progress. To predict diabetes mellitus in this review, we utilized a choice tree, an arbitrary timberland, and a neural organization

Paracrine action of sFLT-1 secreted by stably-transfected Ehrlich ascites tumor cells and therapy using sFLT-1 inhibits ascites tumor growth in vivo

Background: Vascular endothelial growth factor (VEGF) is known to play a major role in angiogenesis. A soluble form of Flt-1, a VEGF receptor, is potentially useful as an antagonist of VEGF, and accumulating evidence suggests the applicability of sFlt-1 in tumor suppression. In the present study, we have developed and tested strategies targeted specifically to VEGF for the treatment of ascites formation. Methods: As an initial strategy, we produced recombinant sFLT-1 in the baculovirus expression system and used it as a trap to sequester VEGF in the murine ascites carcinoma model. The effect of the treatment on the weight of the animal, cell number, ascites volume and proliferating endothelial cells was studied. The second strategy involved, producing Ehrlich ascites tumor (EAT) cells stably transfected with vectors carrying cDNA encoding truncated form of Flt-1 and using these cells to inhibit ascites tumors in a nude mouse model. Results: The sFLT-1 produced by the baculovirus system showed potent anti-angiogenic activity as assessed by rat cornea and tube formation assay. sFLT-1 treatment resulted in reduced peritoneal angiogenesis with a concomitant decrease in tumor cell number, volume of ascites, amount of free VEGF and the number of invasive tumor cells as assayed by CD31 staining. EAT cells stably transfected with truncated form of Flt-1 also effectively reduced the tumor burden in nude mice transplanted with these cells, and demonstrated a reduction in ascites formation and peritoneal angiogenesis. Conclusions: The inhibition of peritoneal angiogenesis and tumor growth by sequestering VEGF with either sFlt-1 gene expression by recombinant EAT cells or by direct sFLT-1 protein therapy is shown to comprise a potential therapy
