Determining ideal pacing rates to meet physiological needs and optimizing programming to prevent unnecessary right ventricular pacing in dogs requires an understanding of heart rate profiles and applicable pacing technology. The heart rate and rhythm of the dog is complex necessitating investigation of rate requirements of activity and circadian influences. Overlaying this information are a multiplicity of other factors such as age, breed, temperament, cardiovascular disease and underlining rhythm disorders that contribute to the difficulty in making general conclusions. However, all such information permits better implementation of programming options with the goal of better outcomes. In this review (Part 1 of a two-part review) instantaneous heart rate, rolling average heart rate, simple average heart rate, heart rate tachograms, RR interval tachograms (2D, 3D and dynamic), and Poincaré plots (2D, 3D and dynamic) are discussed as they apply to decisions in the determination and examination of pacing rates for dogs programmed in the VVI pacing mode (Ventricular paced, Ventricular sensed, Inhibited pacing). The applicable pacing operations available for three pacemaker companies are reviewed (Abbott, Biotronik/Dextronix, and Medtronic). The programmable options considered include slowest pacing rate without additional features to extend the pacing interval, sleep/rest rate preferences, hysteresis to lengthen pacing interval following intrinsic beats, and intermittent increases in pacing following abrupt loss of intrinsic rhythm. Recommendations are suggested for follow-up of individual dogs with examination of pacing statistics and Holter monitoring.Plant signaling peptides are involved in cell-cell communication networks and coordinate a wide range of plant growth and developmental processes. Signaling peptides generally bind to receptor-like kinases, inducing their dimerization with co-receptors for signaling activation to trigger cellular signaling and biological responses. Fertilization is an important life event in flowering plants, involving precise control of cell-cell communications between male and female tissues. Peptide-receptor-like kinase-mediated signaling plays an important role in male-female interactions for successful fertilization in flowering plants. Here, we describe the recent findings on the functions and signaling pathways of peptides and receptors involved in plant reproduction processes including pollen germination, pollen tube growth, pollen tube guidance to the embryo sac, and sperm cell reception in female tissues.

Debate continues about the benefits of preoperative transarterial chemoembolization (TACE) for treatment of hepatocellular carcinoma (HCC). This study aimed to assess the impact of preoperative TACE on long-term outcomes after curative resection for HCC beyond the Milan criteria.

Patients who underwent HCC resection exceeding the Milan criteria without macrovascular invasion between 2015 and 2018 were identified (n = 393). Short- and long-term outcomes were compared between patients who underwent preoperative TACE and patients who did not before and after propensity score matching (PSM). Factors associated with recurrence after resection were analyzed.

100 patients (25.4%) underwent preoperative TACE. Recurrence-free survival (RFS) and overall survival (OS) were comparable with patients who underwent primary liver resection. 7 patients (7.0%) achieved total necrosis with better RFS compared with patients who had an incomplete response to TACE (P=0.041). PSM created 73 matched patient pairs. In the PSM cohort, preoperative TACE improved RFS (P=0.002) and OS (P=0.003). The maximum preoperatively diagnosed tumor diameter (HR 3.230, 95% CI 1.116-9.353; P=0.031) and hepatitis B infection (HR 2.905, 95%CI 1.281-6.589; P=0.011) were independently associated with favorable RFS after HCC resection.

Preoperative TACE made no significant difference to perioperative complications and was correlated with an improved prognosis after surgical resection for patients with HCC beyond the Milan criteria.

The present study was designed to determine the effect of dietary phosphorus restriction, independent of protein intake, on the urinary protein excretion in patients with proteinuria.

Seventy-one patients with proteinuria were enrolled in a parallel randomized controlled trial study. The patients were randomly allocated to receive either a recommended phosphorus-restricted diet (n=36) or a recommended control diet (n=35), for 8weeks. Akt inhibitor A diet was designed and recommended to participants in a way that both trial groups would receive the same amount of energy and protein and the only significant difference between them was the amount of phosphorus intake. The study outcomes included the changes in spot urine protein-to-creatinine ratio, the changes in serum and urine levels of phosphorus, as well as the changes in estimated glomerular filtration rate (eGFR).

The mean±standard deviation of age, body mass index, and eGFR of the participants were 59±14years, 29±5.5kg/m

, and 56.1±21.7mL/min/1.73m

, respectivin excretion, this change was not significantly different from that of the control diet. Further studies with larger sample sizes and different designs will reveal more evidence for a link between phosphorus intake and proteinuria.

Historically, headache was reported in up to 76% of hemodialysis patients. Some authors suggested that headache resulted from caffeine withdrawal. This study aims to compare the incidence of headache and hypotension between patients drinking regular or decaffeinated coffee during dialysis.

One-hundred fifty-six patients were enrolled in this randomized, double-blind, placebo-controlled, multicenter study. Patients with atrial fibrillation were excluded. Group A was given 80mL of regular coffee and group B 80mL of decaffeinated coffee (placebo) in the middle of the session for 12 consecutive sessions. Ultrafiltration rate was fixed to a maximum of 13mL/kg/hour. The primary outcome was the incidence of headache during dialysis.

A total of 139 patients completed the trial (6.4% vs. 15.4% of withdrawal in Groups A and B, respectively). The number of sessions with headache was not significantly different between Group A and B (33.3% vs. 37.1% respectively, P=.522), nor the number of sessions with hypotension (27% vs.
