Cost-effective fabrication of a high-conductivity copper electrode for heterojunction solar cells via laser-induced selective metallization.

Replacing expensive silver with inexpensive copper for the metallization of silicon wafer solar cells can lead to significant reductions in material costs associated with cell production, but the susceptibility of the Cu material to oxidation remains a challenging issue to solve. In this study, we investigate copper metallization of Indium Tin Oxide surfaces to define copper grid electrodes for heterojunction cells. We propose a novel laser-induced selective metallization (LISM) method to fabricate large-scale copper electrodes for heterojunction solar cells at low cost.

What are optimum cycles for immediate primary closure of large cutaneous defects?

Background: In the reconstruction of large complex cutaneous wounds, a myriad of mechanical devices has been designed to facilitate primary wound closure.

BATF and BATF3 deficiency alters CD8+ effector/exhausted T cells balance in skin transplantation.

Background: It is well-established that CD8 T-cells play a critical role in graft rejection. The basic leucine zipper ATF-like transcription factor (BATF) and BATF3 are transcriptional factors expressed in T lymphocytes. Herein, we investigated the functions of BATF and BATF3 in the differentiation and exhaustion of CD8 T cells following alloantigen activation.

[Structure Design of Hip Joint Parallel Rehabilitation Exoskeleton].

At present, most of the research on hip exoskeleton robots adopts the method of decoupling analysis of hip joint motion, decoupling the ball pair motion of hip joint into rotational motion on sagittal plane, coronal plane and cross section, and designing it into series mechanism. Aiming at the problems of error accumulation and man-machine coupling in series mechanism, a parallel hip rehabilitation exoskeleton structure is proposed based on the bionic analysis of human hip joint. The structure model is established and the kinematics analysis is carried out.

The effects of physiotherapeutic scoliosis-specific exercise on idiopathic scoliosis in children and adolescents: a systematic review and meta-analysis.

Background: Physiotherapeutic scoliosis-specific exercise (PSSE) is recommended by SOSORT as the first step in the treatment of adolescent idiopathic scoliosis (AIS). However, a thorough summary and meta-analysis of the evidence for the effectiveness of PSSE is lacking.

Objective: To summarise the up-to-date evidence on the efficacy of PSSE in AIS compared with the other non-surgical therapies.

Activation of NRF2 Signaling Pathway Delays the Progression of Hyperuricemic Nephropathy by Reducing Oxidative Stress.

Hyperuricemia (HUA)-induced oxidative stress is a crucial contributor to hyperuricemic nephropathy (HN), but the molecular mechanisms underlying the disturbed redox homeostasis in kidneys remain elusive. Using RNA sequencing, together with biochemical analyses, we found that nuclear factor erythroid 2-related factor 2 (NRF2) expression and nuclear localization levels were increased in early HN progression and then gradually declined below the baseline level. We identified the impaired activity of the NRF2-activated antioxidant pathway as a driver of oxidative damage in HN progression.

Inhibiting NFAT5 With KRN2 Mitigates Acute Allograft Rejection in a Murine Heart Transplantation Model.

Despite advancements in immunosuppressive therapy, acute allograft rejection remains an important challenge for heart transplantation patients. Nuclear factor of activated T-cells 5 (NFAT5), a member of the family of Rel homology domain-containing factors that plays an important role in regulating immune responses of T lymphocytes, may be closely associated with cardiac rejection. KRN2, as a specific inhibitor of NFAT5, is injected intraperitoneally daily starting from day 0 after murine heart transplantation.

Regulatory mechanisms of the edible alga Ulva lactuca polysaccharide via modulation of gut microbiota in diabetic mice.

In this study, Ulva lactuca polysaccharide (ULP) antihyperglycemic effect was assessed by monitoring changes in the gut microbiota of aging diabetic mice. The results showed that ULP alleviated type 2 diabetes by improving insulin tolerance, increasing SOD and CAT activities, and thus lowering blood glucose level. Moreover, ULP regulated the expressions of INSR and AMPK concurrent with inhibition the expression of JNK, JAK, STAT3, p16 and p38 to improve glucose metabolism dysfunction.

Correlation coefficient-directed label-free characterization of native proteins by surface-enhanced Raman spectroscopy.

Investigation of proteins in their native state is the core of proteomics towards better understanding of their structures and functions. Surface-enhanced Raman spectroscopy (SERS) has shown its unique advantages in protein characterization with fingerprint information and high sensitivity, which makes it a promising tool for proteomics. It is still challenging to obtain SERS spectra of proteins in the native state and evaluate the native degree.

Raman spectroscopic insight into charge delocalization-improved electrical conductivity in metal-cyanide frameworks.

Porous crystalline materials (PCMs) have attracted widespread attention due to their high porosity and chemical tunability. To solve the problem of the low electrical conductivity of traditional PCMs, a guest-promoted approach has been developed to impart electrical conductivity, whereas microscopic understanding of this process from experiments is largely lacking. Here we use electrochemical surface-enhanced Raman spectroscopy (EC-SERS) to investigate the microscopic mechanism of the enhanced electrical conductivity in metal-cyanide frameworks, in Prussian Blue (PB), induced by alkali metal ions.

PVA-assisted CNCs/SiO composite aerogel for efficient sorption of ciprofloxacin.

Efforts to develop a green, inexpensive and effective adsorbent are crucial for eliminating antibiotics in polluted water. The sorption capacity of the as-prepared polyvinyl alcohol (PVA)-assisted cellulose nanocrystals/SiO (CNCs/SiO) composite aerogel to ciprofloxacin (CIP) rises with the increase of temperature and initial concentration. Reverse trend of sorption capacity can be found when increasing the adsorbent dosage of adsorbent.

Parental Factors Associated With Physical Activity Among East Asian Children/Youth: A Meta-Analysis Based on the Active Healthy Kids Report Cards.

Insufficient physical activity (PA) is a leading risk factor for mortality. The Active Healthy Kids Report Cards provide comprehensive evidence related to PA in children/adolescents. Associations of (1) parental support for PA with amount of moderate-to-vigorous-intensity PA (MVPA) performed by children/adolescents and (2) amount of MVPA performed by parents with amount of MVPA performed by children/adolescents, as indicated by Report Cards, have not been critically synthesized in meta-analysis.

Improving Research Patient Data Repositories From a Health Data Industry Viewpoint.

Organizational, administrative, and educational challenges in establishing and sustaining biomedical data science infrastructures lead to the inefficient use of Research Patient Data Repositories (RPDRs). The challenges, including but not limited to deployment, sustainability, cost optimization, collaboration, governance, security, rapid response, reliability, stability, scalability, and convenience, restrict each other and may not be naturally alleviated through traditional hardware upgrades or protocol enhancements. This article attempts to borrow data science thinking and practices in the business realm, which we call the data industry viewpoint, to improve RPDRs.
