Feedback control effect on the Lotka-Volterra prey-predator system with discrete delays

In this paper, we study a Lotka-Volterra prey-predator system with feedback control. We establish sufficient conditions under which a unique positive equilibrium is globally stable. Further, we show that a suitable feedback control on predator species can make prey species that is on the brink of extinction become globally stable, but under the conditions of small feedback...

Almost periodic solution of a discrete Nicholson’s blowflies model with delay and feedback control

In this paper, we propose a discrete Nicholson’s blowflies model with feedback control. Sufficient conditions are obtained for the permanence. By means of an almost periodic functional hull theory, we show that the almost periodic system has a uniqueness of globally attractive almost periodic solution. Moreover, a suitable example and its numerical simulation are given to...

Activation of NLRP3 inflammasomes contributes to hyperhomocysteinemia-aggravated inflammation and atherosclerosis in apoE-deficient mice

Hyperhomocysteinemia (HHcy) has been shown to promote vascular inflammation and atherosclerosis, but the underlying mechanisms remain largely unknown. The NLRP3 inflammasome has been identified as the cellular machinery responsible for activation of inflammatory processes. In this study, we hypothesized that the activation of NLRP3 inflammasomes contributes to HHcy-induced...

Note on the Persistence of a Nonautonomous Lotka-Volterra Competitive System with Infinite Delay and Feedback Controls

We study a nonautonomous Lotka-Volterra competitive system with infinite delay and feedback controls. We establish a series of criteria under which a part of -species of the systems is driven to extinction while the remaining part of the species is persistent. Particularly, as a special case, a series of new sufficient conditions on the persistence for all species of system are...

Analysis and Recognition of Traditional Chinese Medicine Pulse Based on the Hilbert-Huang Transform and Random Forest in Patients with Coronary Heart Disease

Objective. This research provides objective and quantitative parameters of the traditional Chinese medicine (TCM) pulse conditions for distinguishing between patients with the coronary heart disease (CHD) and normal people by using the proposed classification approach based on Hilbert-Huang transform (HHT) and random forest. Methods. The energy and the sample entropy features...

Lack of Association between Interleukin-10 Gene Polymorphisms and Graft Rejection Risk in Kidney Transplantation Recipients: A Meta-Analysis

Background Interleukin-10 (IL-10) is an important immunomodulatory cytokine. Several studies focused the association between IL-10 promoter gene polymorphisms and graft rejection risk in kidney transplantation recipients. However, the results of these studies remain inconclusive. The aim of this study was to conduct a meta-analysis to further assess the associations. Methods The...

Drosophila Morgue Associates with SkpA and Polyubiquitin In Vivo

Morgue is a unique ubiquitination protein that influences programmed cell death and circadian rhythms in Drosophila. We have found that over-expression of wild-type Morgue results in organismal lethality. This over-expression phenotype was used as the basis for an in vivo functional assay to investigate the importance of the Morgue zinc finger, F box, Ubiquitin E2 Conjugase...

Abnormal expression of CDK11p58 in prostate cancer

Background CDK11p58 is one of the large families of p34cdc2-related kinases whose functions are linked with cell cycle progression, tumorigenesis and apoptotic signaling. Our previous investigation demonstrated that CDK11p58 repressed androgen receptor (AR) transcriptional activity and was involved in the negative regulation of AR function. Methods CDK11p58 expression was...

A molecular signature for the prediction of recurrence in colorectal cancer

Background Several clinical and pathological factors have an impact on the prognosis of colorectal cancer (CRC), but they are not yet adequate for risk assessment. We aimed to identify a molecular signature that can reliably identify CRC patients at high risk for recurrence. Results Two hundred eighty-one CRC samples (stage II/III) were included in this study. A two-step gene...

Nitric oxide: promoter or suppressor of programmed cell death?

Nitric oxide (NO) is a short-lived gaseous free radical that predominantly functions as a messenger and effector molecule. It affects a variety of physiological processes, including programmed cell death (PCD) through cyclic guanosine monophosphate (cGMP)-dependent and — independent pathways. In this field, dominant discoveries are the diverse apoptosis networks in mammalian...

Abnormal expression of GADD45B in human colorectal carcinoma

Background GADD45B is a member of the growth arrest DNA damage-inducible gene family associated with cell growth control, apoptosis, and DNA damage repair response. The aim of this study is to detect the role of GADD45B in colorectal carcinoma (CRC); the area not studied in depth to date. Methods The mRNA and protein levels of GADD45B were examined by Real-Time quantitative PCR...

A Rice Plastidial Nucleotide Sugar Epimerase Is Involved in Galactolipid Biosynthesis and Improves Photosynthetic Efficiency

Photosynthesis is the final determinator for crop yield. To gain insight into genes controlling photosynthetic capacity, we selected from our large T-DNA mutant population a rice stunted growth mutant with decreased carbon assimilate and yield production named photoassimilate defective1 (phd1). Molecular and biochemical analyses revealed that PHD1 encodes a novel chloroplast...

S-Nitrosylation: an emerging redox-based post-translational modification in plants

S-nitrosylation, the covalent attachment of a nitric oxide moiety to a cysteine thiol, is now established as a key post-translational modification in animals. This process has been shown to regulate the function of a wide variety of regulatory, structural, and metabolic proteins. The emerging evidence now suggests that S-nitrosylation may also have a central function in plant...

Nitric oxide function and signalling in plant disease resistance

Nitric oxide (NO) is one of only a handful of gaseous signalling molecules. Its discovery as the endothelium-derived relaxing factor (EDRF) by Ignarro revolutionized how NO and cognate reactive nitrogen intermediates, which were previously considered to be toxic molecules, are viewed. NO is now emerging as a key signalling molecule in plants, where it orchestrates a plethora of...
