01), ICD shocks (SMD -1.71, 95% CI -3.0 to -0.42, p<.01) and anti-tachycardia pacing (SMD -1.21, 95% CI -1.98 to -0.44, p<.01) following RSDN denervation. The pooled incidence of all-cause mortality after RSDN was 10.16% (95% CI 1.08 to 24.12). There were no major vascular complications, one minor vascular complication-small non-flow limiting renal artery dissection (no intervention needed).

RSDN appears to be a safe and effective treatment strategy in patients with prior failed antiarrhythmic drugs and catheter ablation for recurrent ventricular arrhythmia and electrical storm.

A simple and rapid detection method for 17β-estradiol (E

) in complex food matrix is greatly desirable. A magnetic relaxation switch (MRS) sensor for detecting E

based on the aptamer-functionalized gold-coated iron oxide (Fe

O

@Au) nanocomposite was designed in this study. Fe

O

@Au nanoparticles (NPs) played as a 'switch' between dispersed and aggregated states, while aptamer served as the recognition unit.

According to the sensing effect of monocomponent relaxation time (T

) for E

, the volume ratio of aptamers to Fe

O

@Au, the sodium chloride (NaCl) concentration, the concentration of Fe

and 15 min, respectively. Tamoxifen cost For the analysis of food sample, the E

was quantified over a concentration range of 1 to 100 nmol L

with a detection limit of 7.6 nmol L

for milk samples, while a linearity range of 20 to 100 nmol L

and a detection limit of 8.57 nmol L

for egg samples.

Computed tomography (CT) has an established role in detecting perforation of implanted pacemaker and defibrillator leads. The clinical significance of incidental finding of delayed lead perforation remains unclear. The aim of this study was to assess the prevalence of lead perforation as detected by CT in a cohort of patients undergoing transvenous laser lead extraction and characterize the association between finding of incidental lead perforation with periprocedural outcomes.

Consecutive patients that underwent chest CT and lead extraction were retrospectively assessed for presence of lead perforation. A total of 143 patients and 348 leads were assessed. The finding of lead perforation was correlated with findings from peri-procedural transesophageal echocardiography (TEE) and outcomes of the lead extraction procedure.

Lead perforations (including perforations<5mm and ≥5mm) were detected in 66 (46%) patients and 73 (21%) leads. Lead perforation ≥5mm were less common and detected in 13 (9%) of patients and 14 (4%) of leads. There was no significant difference in the rates of peri-procedural death, cardiac avulsion, cardiac tamponade or post-extraction pericardial effusion in patients with and without lead perforation.

Incidental delayed lead perforations detected by CT are common and do not correlate with significant TEE findings or adverse peri-procedural outcomes in patients undergoing lead extraction. Larger studies are needed to further characterize the frequency and safety of these findings.

Salinity and drought stresses have become widespread in many regions of the world. Although there are several studies, their findings about the response of lettuce to water and salinity stresses are contradictory. This paper therefore aims to evaluate the effects of water deficit and irrigation water salinity on growth, yield, and water consumption of iceberg lettuce. For these purposes, two experiments were carried out under Mediterranean conditions.

The water yield response factors (K

) determined for the lettuce plant grown under stress conditions caused by water (K

= 1.69) and irrigation water salinity (K

= 2.62) were quite different from each other. The classical salinity tolerance model did not reflect the results accurately because the fresh yield and plant water consumption of lettuce increased sharply with increasing soil salinity up to 2.17 dS m

and then decreased slightly after this value. Thus, a new model was created to reflect both the increase and decrease in fresh yield. The actual salt tolerance model for iceberg lettuce plant showed that the optimum salinity is 1.84 dS m

with relative yield decreases of 8.26 and 22.7% per unit salinity increase above and below the optimum salinity level, respectively.

Lettuce fresh yield at soil salinity below the optimum salinity experienced greater reduction than at soil salinity above the optimum value. The results reveal that the use of low-salinity irrigation water should be preferred to increase fresh yield in iceberg lettuce cultivation. © 2021 Society of Chemical Industry.

We hypothesised that the fern dictyostele structure affects air entry into the xylem, and therefore impacts the shape of the vulnerability curve. Our study examined this variation by comparing vulnerability curves constructed on petioles collected from evergreen and deciduous ferns in the field, with curves generated using the standard centrifuge, air-injection and bench-top dehydration methods. Additional experiments complemented the vulnerability curves to better understand how anatomy shapes estimates of cavitation resistance. Centrifugation and radial air injection generated acceptable vulnerability curves for the deciduous species, but overestimated drought resistance in the two evergreen ferns. In these hardy plants, axial air injection and bench-top dehydration produced results that most closely aligned with observations in nature. Additional experiments revealed that the dictyostele anatomy impedes air entry into the xylem during spinning and radial air injection.
