We study an impulsive delay differential predator–prey model with Holling type II functional response. The stability of the trivial equilibrium is analyzed by means Floquet theory providing a sufficient condition for extinction. Using coincidence degree we show existence positive periodic solutions. system then numerically, revealing that presence delays and impulses may lead to chaotic solutions, quasi-periodic or multiple Several simulations examples are presented.

In the present study, maize starch (MS), potato (PS), high-amylose (HAMS), and wheat (WS) were deep-fried in soybean oil that was continuously heated for 40 h under 180 °C. The thermodynamic pasting properties of samples determined. results suggested starch–lipid complexes formed with extension frying oils’ usage; however, their number not dependent on life cycle. Importantly, revealed following strength intermolecular force samples: PS > MS HAMS WS. XRD FTIR analysis confirmed formation...

Spinal cord injury (SCI) induces both motor and sensory dysfunctions. We wondered whether miR-30b could promote primary neuron (PSN) axon growth in inhibitory microenvironment. The neurite was promoted by agomir inhibited antagomir. MiR-30b targeted degraded sema3A mRNA. regulated the formation of sema3A-NRP-1-PlexinA1 complex via targeting sema3A. length induced agomir, application protein reverse effect agomir. GTP-RhoA ROCK expression were down-regulated miR-30b. Neurite outgrowth that...

Abstract Introduction To analyze the application of 3D printed osteotomy guide plate-assisted total knee arthroplasty (TKA) for valgus deformity. Methods The clinical data 20 patients with deformity admitted to our hospital from April 2012 2017 were collected and analyzed. According treatment method, these divided into two groups: TKA (combined group, n = 10) (treatment 10). operation time, intraoperative bleeding volume, postoperative mean femorotibial angle (MFTA), Knee Society Score (KSS)...

Background. Perioperative topical tranexamic acid as antifibrinolytic agent is often used for total joint replacement to reduce bleeding currently. Staphylococcus aureus was the most common isolates from perioperative infection of prosthetic joint. The influence application with on incidence acute has not been clarified. Methods. Mouse model knee prosthesis constructed. Tranexamic intra-articular injected during period. CFU counting tissue and implant sample evaluated 3 days 7 after...
