Kinetics of transcription initiation directed by multiple cis-regulatory elements on the glnAp2 promoter

Transcription initiation is orchestrated by dynamic molecular interactions, with kinetic steps difficult to detect. Utilizing a hybrid method, we aim to unravel essential kinetic steps of transcriptional regulation on the glnAp2 promoter, whose regulatory region includes two enhancers (sites I and II) and three low-affinity sequences (sites III-V), to which the transcriptional ...

Robust group compressive sensing for DOA estimation with partially distorted observations

In this paper, we propose a robust direction-of-arrival (DOA) estimation algorithm based on group sparse reconstruction algorithm utilizing signals observed at multiple frequencies. The group sparse reconstruction scheme for DOA estimation is solved through the complex multitask Bayesian compressive sensing algorithm by exploiting the group sparse property of the received ...

Prevalence and risk factors for cardiovascular disease among chronic kidney disease patients: results from the Chinese cohort study of chronic kidney disease (C-STRIDE)

Background Although a high incidence of cardiovascular disease (CVD) is observed among chronic kidney disease (CKD) patients in developed countries, limited information is available about CVD prevalence and risk factors in the Chinese CKD population. The Chinese Cohort of Chronic Kidney Disease (C-STRIDE) was established to investigate the prevalence and risk factors of CVD among ...

Analysis of the Negative-SET Behaviors in Cu/ZrO2/Pt Devices

Metal oxide-based electrochemical metallization memory (ECM) shows promising performance for next generation non-volatile memory. The negative-SET behavior has been observed in various oxide-based ECM devices. But the underlying mechanism of this behavior remains unaddressed and the role of the metal cation and oxygen vacancy in this behavior is unclear. In this work, we have ...

Interocular symmetry of the peripapillary choroidal thickness and retinal nerve fibre layer thickness in healthy adults with isometropia

Background The aim of this study was to determine the interocular differences in the peripapillary retinal nerve fibre layer (RNFL), peripapillary choroidal thickness (PCT) and subfoveal choroidal thickness (SFCT) in healthy adults with isometropia, using enhanced depth imaging optical coherence tomography (EDI SD-OCT). Methods One hundred healthy Chinese adults with spherical ...

Challenges for strengthening the health workforce in the Lao People’s Democratic Republic: perspectives from key stakeholders

Background The Lao People’s Democratic Republic is facing a critical shortage and maldistribution of health workers. Strengthening of the health workforce has been adopted as one of the five priorities of the National Health Sector Strategy (2013–2025). This study aims to identify, explore, and better understand the key challenges for strengthening the Laotian health workforce. ...

Multiple statuses of through-wall human being detection based on compressed UWB radar data

Ultra-wideband (UWB) radar is one of the most favorable methods for through-wall human detection due to its strong penetration ability in many common non-metallic obstructions. The paper proposed the residual subspace projection method for multiple statuses of through-wall human being detection behind. And the compressed sensing method was presented to collect incomplete UWB radar ...

Increased expression of TROP2 in airway basal cells potentially contributes to airway remodeling in chronic obstructive pulmonary disease

Background The airway epithelium of chronic obstructive pulmonary disease (COPD) patients undergoes aberrant repair and remodeling after repetitive injury following exposure to environmental factors. Abnormal airway regeneration observed in COPD is thought to originate in the stem/progenitor cells of the airway epithelium, the basal cells (BCs). However, the molecular mechanisms ...

Lipedematous alopecia: clinical and histological analysis of the first male Chinese

Background Lipedematous alopecia (LA) is a rare disorder clinically characterized by a thick boggy scalp and varying severity of hair loss, which primarily occurs in black female adults. In this study, we reported one male adult Chinese diagnosed with lipedematous alopecia for the first time. Case presentation A Chinese male, aged 20 years old, admitted to Shandong Provincial ...

Comparison of the complications of traditional 12 cores transrectal prostate biopsy with image fusion guided transperineal prostate biopsy

Background To compare the complications of traditional transrectal (TR) prostate biopsy and image fusion guided transperineal (TP) prostate biopsy in our center. Methods Two hundred and fourty-two patients who underwent prostate biopsy from August 2014 to January 2015were reviewed. Among them, 144 patients underwent systematic 12-core transrectal ultrasonography (TRUS) guided ...

\(B_c\rightarrow B_{sJ}\) form factors and \(B_c\) decays into \(B_{sJ}\) in covariant light-front approach

We suggest to study the \(B_{s}\) and its excitations \(B_{sJ}\) in the \(B_c\) decays. We calculate the \(B_c\rightarrow B_{sJ}\) and \(B_c\rightarrow B_{J}\) form factors within the covariant light-front quark model, where the \(B_{sJ}\) and \(B_{J}\) denote an s-wave or p-wave \(\bar{b}s\) and \(\bar{b}d\) meson, respectively. The form factors at \(q^2=0\) are directly computed ...

Size effect of Au/PAMAM contrast agent on CT imaging of reticuloendothelial system and tumor tissue

Polyamidoamine (PAMAM)-entrapped Au nanoparticles were synthesized with distinct sizes to figure out the size effect of Au-based contrast agent on CT imaging of passively targeted tissues. Au/PAMAM nanoparticles were first synthesized with narrow distribution of particles size of 22.2 ± 3.1, 54.2 ± 3.7, and 104.9 ± 4.7 nm in diameters. Size effect leads no significant difference on ...

Dexmedetomidine sedation reduces atrial fibrillation after cardiac surgery compared to propofol: a randomized controlled trial

Background Atrial fibrillation occurs frequently in patients following cardiac surgery and can be a cause of increased morbidity and mortality. The use of dexmedetomidine to prevent atrial fibrillation is unclear. The present study was designed to evaluate the effect of dexmedetomidine sedation on the incidence of atrial fibrillation after cardiac surgery. Methods Upon arrival to ...

Model updating mechanism of concept drift detection in data stream based on classifier pool

In data stream, concept drift often occurs in an unpredictable way, the classifier model which was learned from previous data is not accurate to the current data, so regular updating of the model is necessary. Moreover, updating too frequently will cause a negative impact on the clustering accuracy and the analysis of subsequent data. This paper proposed a model-updating mechanism ...
