New tools for single-cell interrogation enable deeper understanding of cellular heterogeneity and associated cellular behaviors and functions. Information of RNA expression in single cell could contribute to our knowledge of the genetic regulatory circuits and molecular mechanism of disease development. Although significant progresses have been made for intracellular RNA analysis, existing methods have a trade-off between operational complexity and practical feasibility. We address this challenge by combining the ionic current rectification property of nanopipette reactor with duplex-specific nuclease-assisted hybridization chain reaction for signal amplification to realize a simple and practical intracellular nanosensor with minimal invasiveness, which enables single-cell collection and electrochemical detection of intracellular RNA with cell-context preservation. Systematic studies on differentiation of oncogenic miR-10b expression levels in non-malignant breast cells, metastatic breast cancer cells as well as non-metastatic breast cancer cells were then realized by this nanotool accompanied by assessment of different drugs effects. This work has unveiled the ability of electrochemistry to probe intracellular RNA and opened new opportunities to study the gene expression and heterogeneous complexity under physiological conditions down to single-cell level.
Our objective was to study relationships between the new biomarker of vascular health, carotid artery longitudinal wall motion (CALM) and metabolic syndrome (MetS).
Carotid ultrasound and assessment of MetS and its components were performed with 281 subjects aged 30-45years. In the longitudinal motion analysis, the amplitude of motion and the antegrade-oriented and retrograde-oriented components of motion between the intima-media complex and adventitial layer of the common carotid artery wall were assessed.
Metabolic syndrome, according to the harmonized criteria, was detected in 53 subjects (19%). MetS was significantly associated with increased antegrade and decreased retrograde longitudinal motion in the carotid artery wall. Augmented antegrade amplitude of longitudinal motion was associated with obesity (β=0.149, p<.05) and low HDL cholesterol (β=0.177, p<.01). Attenuated retrograde amplitude of longitudinal motion was associated with hypertension (β=-0.156, p<.05), obesity (β=-0.138, p<.05) and hyperinsulinaemia (β=-0.158, p<.01). Moreover, insulin resistance (homeostasis model assessment index above 2.44) was associated with adverse changes in CALM.
Metabolic syndrome and insulin resistance were associated with alterations in CALM. In particular, hypertension, obesity and hyperinsulinaemia were associated with reduced total peak-to-peak amplitude as well as increased antegrade and reduced retrograde amplitudes, all of which might be markers of unfavourable vascular health.

The outcome of this procedure significantly depends on the method of recipient site preparation, a critical step to achieve cosmetically acceptable repigmentation. To compare the efficacy of recipient site preparation using three methods namely, dermabrasion, cryoblister, and dermaroller followed by NCES in stable vitiligo. In this single-center, prospective, intra-patient, randomized clinical trial; 36 participants having at least three vitiligo patches in same anatomic region with minimum lesional stability of 1 year were randomized 111 for recipient site preparation using manual dermabrasion, cryoblister, and dermaroller followed by NCES. Patients were followed up at 4, 8, and 12 weeks and assessment of extent and pattern of repigmentation, color match and patient satisfaction were done. Among 36 patients, 22 (61.1%) were females; mean (SD) age was 28.33 (9.4) years. Dermabrasion and cryoblister techniques showed equal efficacy with respect to extent of repigmentation (>75% repigmentation; 55.6% vs 47.2%; P = .63) and patient satisfaction score (20.2 ± 9.6 vs 19.9 ± 7.9, P = .194). However, dermabrasion was superior to cryoblister in terms of rapidity (65% vs 32.5% at 4 weeks, P = .04) and color match (47.2% vs 19.4%, P = .004). Dermaroller had poor repigmentation outcomes compared to both dermabrasion and cryoblister. Cryoblister as a method of recipient site preparation is equally effective as manual dermabrasion in NCES for attaining good to excellent repigmentation, but with risk of hyperpigmentation. However, dermaroller is inferior to both dermabrasion and cryoblister.
Cystoscopic placement of ureteric stents during colorectal surgery (CRS) may aid in the intraoperative identification of the ureters and thus prevent ureteric injury, but may also be associated with prolonged operating time, increased cost and adverse events. No formal recommendations exist regarding the use of ureteric stents prior to CRS. Our aim was to determine the effect of prophylactic ureteric stent insertion on the risk of ureteric injury among adult patients undergoing CRS.
A systematic search using the Ovid platform was completed. The primary outcome was risk of ureteric injury. Secondary outcomes included the risk of acute kidney injury (AKI), urinary tract infection (UTI), sepsis, length of stay (LOS) and mortality. The Paule-Mandel pooling and a random effects model was used to produce odds ratios (ORs) with 95% confidence intervals (CIs) for binary outcomes. Standardized mean differences (MD) were reported for continuous variables. Analyses were completed using R3.5.
Nine retrospective cohort studies evaluating 98507 patients were included. The incidence of ureteric injury was 0.6%. Docetaxel Overall, 5.1% of patients underwent ureteric stenting. There was no change in the odds of ureteric injury among stented patients compared with controls (OR 1.30, 95% CI 0.39-4.29, I
=25%). Operating time was significantly longer (MD 49.3min, 95% CI 35.3-63.4, I
=96%) in the intervention group. There was no difference in rates of AKI, UTI, sepsis, LOS or mortality between groups.
Given the retrospective nature of the identified studies, the benefit of prophylactic ureteric stenting remains uncertain. Prophylactic ureteric stenting was not associated with increased patient morbidity but did significantly increase operating time.
