Arabidopsis thaliana has eight genes encoding members of the type 1(B) heavy metal-transporting subfamily of the P-type ATPases. Three of these transporters, HMA2, HMA3, and HMA4, are closely related to each other and are most similar in sequence to the divalent heavy metal cation transporters of prokaryotes. To determine the function of these transporters… (More)
BACKGROUND Research into the etiology of breast cancer has recently focused on the role of the immunity and inflammation. The proinflammatory cytokines IL-17A and IL-17F can mediate inflammation and cancer. To evaluate the influences of IL-17A and IL-17F gene polymorphisms on the risk of sporadic breast cancer, a case-control study was conducted in Chinese… (More)
Imperfect bifurcation phenomena are formulated in framework of analytical bifurcation theory on Ba-nach spaces. In particular the perturbations of transcritical and pitchfork bifurcations at a simple eigenvalue are examined, and two-parameter unfoldings of singularities are rigorously established. Applications include semilinear elliptic equations,… (More)
In the study, we investigated how exogenous H2S (hydrogen sulfide) influenced streptozotocin (STZ)-induced diabetic myocardial injury through cardiac mitochondrial protection and nitric oxide (NO) synthesis in intact rat hearts and primary neonatal rat cardiomyocytes. Diabetes was induced by STZ (50 mg/kg) and the daily administration of 100 μM NaHS (sodium… (More)
BACKGROUND Patients with type 2 diabetes (DM) have a higher risk of developing pulmonary tuberculosis (PTB); moreover, DM co-morbidity in PTB is associated with poor PTB treatment outcomes. Community based prevalence data on DM and prediabetes (pre-DM) among TB patients is lacking, particularly from the developing world. Therefore we conducted a prospective… (More)
Bifurcations of spatially nonhomogeneous periodic orbits and steady state solutions are rigorously proved for a reaction–diffusion system modeling Schnaken-berg chemical reaction. The existence of these patterned solutions shows the richness of the spatiotemporal dynamics such as oscillatory behavior and spatial patterns.
We are concerned with the uniqueness and existence of positive solutions for the following problem: where p i > 0(i = 1, 2, 3) and D is a smooth domain in R n. If D is a ball in R n , we prove the uniqueness of positive radially symmetric solution.
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository. Authors requiring further information regarding Elsevier's archiving and manuscript policies are encouraged to visit: a r t i c l e i n f o a b s t r a c t The dynamics and steady state solutions of an… (More)
Knowing the actual behavior of readers will help us understand how near work influences a reader's eyes, comfort, reading efficiency, pleasure, and the ability to learn to read. We designed a methodology for reading behavior research, and investigated the reading behavior of emmetropic schoolchildren in China and factors that influence their reading.… (More)
Development in Near Space Vehicle communication has increased the need for simulation to test and analyze protocols for this emerging technology. Network simulators lack a realistic near space path loss and fading module which would allow having accurate simulation. To explore and simulate accurately the influence of rain, cloud, gaseous absorption and… (More)
