Thermally Activated Delayed Fluorescence-Based Near-Infrared-II Luminescence and Controlled Size Growth of Silver Nanoclusters.

Due to the significant relationships between structure and properties, the controlled construction of atomically precise metal clusters presents both a formidable challenge and great importance. The innovative synthesis of well-defined silver nanoclusters with near-infrared II (NIR-II) luminescent properties may inspire further exploration of functional metal nanoclusters for bioimaging applications. In this study, we employed the multidentate chelating nitrogen ligand 3,5-di(2-pyridyl)pyrazole (Hbpypz) to construct three unprecedented silver nanoclusters: [Ag(bpypz)] (), [Ag(bpypz)] (), and [Ag(bpypz)] ().

This study assessed the medical records of 12 patients with severe pertussis requiring ET therapy who were admitted to our medical center. Of the 12 patients requiring ET therapy, 8 survived and 4 died.

Effects of the salbutamol bronchodilator response on measurements of fractional exhaled nitric oxide in children with asthma: a prospective, observational study.

Background: Salbutamol bronchodilator response (BDR) test and fractional exhaled nitric oxide (FeNO) have been recommended for the diagnosis of asthma in children, but FeNO levels is affected by many factors. Nonetheless, data of the effect on the FeNO values throughout the bronchodilator test and the differences in FeNO values between BDR positive (BDR+) and negative (BDR-) children with asthma are still limited. We aimed to evaluate the effect of the BDR test on FeNO and the differences in FeNO levels between BDR+ and BDR- children with asthma.

Impaired visual, working, and verbal memory in first-episode, drug-naive patients with major depressive disorder in a Chinese population.

Cognitive impairment has been observed in patients with major depressive disorder (MDD). However, it remains unclear whether the deficits in specific cognitive domains are present in first-episode, drug-naïve patients or medicated patients. In the present study, using the CogState battery (CSB) Chinese language version, we evaluated the visual, working, and verbal memory in first-episode drug-naive patients and medicated patients with MDD in a Chinese population.

A 2-year step-down withdrawal from inhaled corticosteroids in asthmatic children receiving immunotherapy.

Background: Inhaled corticosteroids (ICSs) for treating asthma are controversial because of their negative effects on the growth of asthmatic children and without clearly defined withdrawal strategy. A 2-year ICS step-down and withdrawal strategy has been developed for asthmatic children receiving 3-year subcutaneous immunotherapy (SCIT).

Methods: Eleven children were included into the SCIT group and 13 children into the ICS group.

Absence of PTHrP nuclear localization and C-terminus sequences leads to abnormal development of T cells.

Parathyroid hormone-related protein (PTHrP), a ubiquitously expressed protein, is composed of four functional domains including N-terminus, mid region, nuclear localization signal (NLS) and C-terminus. Under the direction of NLS, PTHrP can enter cell nucleus from cytoplasm and stimulate mitogenesis. Although PTHrP is considered to have important developmental roles, the role of PTHrP NLS and C-terminus in developmental process remains unknown, especially in T-cell development.

iTRAQ-based Quantitative Proteomics Study in Patients with Refractory Mycoplasma pneumoniae Pneumonia.

Mycoplasma pneumoniae (MP) is a leading cause of community-acquired pneumonia in children and young adults. Although MP pneumonia is usually benign and self-limited, in some cases it can develop into life-threating refractory MP pneumonia (RMPP). However, the pathogenesis of RMPP is poorly understood.

Hypoxemia is an independent predictor of bronchiolitis obliterans following respiratory adenoviral infection in children.

Bronchiolitis obliterans (BO) is an uncommon and severe sequela of chronic obstructive lung disease in children that results from an insult to the lower respiratory tract. Few prognostic factors achieved worldwide acknowledgment. In the present study, we retrospectively collected the children with respiratory adenoviral infection and identified the predictive factors of BO.

Intranasal Delivery of Recombinant AAV Containing BDNF Fused with HA2TAT: a Potential Promising Therapy Strategy for Major Depressive Disorder.

Depression is a disturbing psychiatric disease with unsatisfied therapy. Not all patients are sensitive to anti-depressants currently in use, side-effects are unavoidable during therapy, and the cases with effectiveness are always accompanied with delayed onset of clinical efficacy. Delivering brain-derived neurotrophic factor (BDNF) to brain seems to be a promising therapy.

Intranasal Delivery of Recombinant NT4-NAP/AAV Exerts Potential Antidepressant Effect.

The present study was designed to construct a recombinant adeno-associated virus (rAAV) which can express NAP in the brain and examine whether this virus can produce antidepressant effects on C57 BL/6 mice that had been subjected to open field test and forced swimming test, via nose-to-brain pathway. When the recombinant plasmid pGEM-T Easy/NT4-NAP was digested by EcoRI, 297 bp fragments can be obtained and NT4-NAP sequence was consistent with the designed sequence confirmed by DNA sequencing. When the recombinant plasmid pSSCMV/NT4-NAP was digested by EcoRI, 297 bp fragments is visible.

Effects of immobilization stress on emotional behaviors in dopamine D3 receptor knockout mice.

A central problem in understanding the dopamine system in anxiety and depression is to specify functions of different members of the dopamine receptor family. Recent studies have reported that the dopamine D2/D3 receptor agonist pramipexole exerts an antidepressant-like effect in the chronic mild stress model and in the behavioral despair model, suggesting dopamine D3 receptor may be an important target for antidepressant actions. The aim of the present study was to examine the role of dopamine D3 receptor on the anxiety-like and depression-like behaviors induced by immobilization stress.

Dlx2 over-expression: a possible mechanism for first branchial arch malformation.

The first branchial arch malformation (FBAM) is a rare congenital defect associated with anomalous development of the first and second branchial arches. Cause of FBAM still remains unknown, and is thought in most cases to be multifactorial, involving both genetic and enviromental factors. Dlx2 as a member of the Dlx homeobox gene family, plays a crucial role in the development of the first branchial arch.
