The intact and healthy skin forms a barrier to the outside world and protects the body from mechanical impact. The skin is a complex structure with unique mechano-elastic properties. To better direct the design of biomimetic materials and induce skin regeneration in wounds with optimal outcome, more insight is required in how the mechano-elastic properties emerge from the skin's main constituents, collagen and elastin fibers.

Increases in the prevalence of food allergy and vitamin D deficiency have been observed in recent years. The association between vitamin D levels and food allergy remains to be fully elucidated, and research focused on the prevalence of vitamin D insufficiency in infants with food protein-induced gastrointestinal disease in Chengdu, Sichuan is lacking. Thus, the present study aimed to determine the prevalence and clinical characteristics of serum 25 hydroxyvitamin D [25-(OH)D] insufficiency and sufficiency in infants with food protein-induced gastrointestinal disease.

Background: Hypertrophic cardiomyopathy (HCM) is an underdiagnosed genetic heart disease worldwide. The management and prognosis of obstructive HCM (HOCM) and non-obstructive HCM (HNCM) are quite different, but it also remains challenging to discriminate these two subtypes. HCM is characterized by dysmetabolism, and myocardial amino acid (AA) metabolism is robustly changed.

Background: Hypertrophic cardiomyopathy (HCM) is a widely distributed, but clinically heterogeneous genetic heart disease, affects approximately 20 million people worldwide. Nowadays, HCM is treatable with the advancement of medical interventions. However, due to occult clinical presentations and a lack of easy, inexpensive, and widely popularized screening approaches in the general population, 80-90% HCM patients are not clinically identifiable, which brings certain safety hazards could have been prevented.

Importance: Patients with hypertrophic obstructive cardiomyopathy (HOCM) and drug-refractory symptoms and outflow gradients have limited nonsurgical treatment options. The feasibility of percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) has been reported previously; however, procedural and medium-term outcomes are unknown.

Objective: To describe the safety and medium-term outcomes of PIMSRA in a large patient cohort with drug-refractory HOCM.

() is a foodborne pathogen that has caused numerous outbreaks worldwide, necessitating the development of on-site strategy to prevent early contamination. Here, we set up an enzyme-free strategy for aptamer-catalyzed hairpin assembly in which salt-induced aggregation of unmodified gold nanoparticles (AuNPs) served as a colorimetric signal output, allowing on-site detection of in milk. The aptamer-functionalized magnetic beads were used as a vehicle of specifically enriching target bacteria which conjugated with target aptamer to trigger the "Y" shape catalytic hairpin assembly (Y-CHA) circuit.

Symbiotic gut microbiota in early life plays a vital role in human health, and changes in its communication and function are associated with various complex disorders. In this study, we analyzed the gut flora communication of 6 infants at 4 months of age and determined the disturbances related to antibiotic treatment. By the culturomics and Single Molecule Real-time sequencing methods, a total of 6234 strains were divided into 16 genera and 45 species.

After a sublethal ischemic preconditioning (IPC) stimulus, the brain has a remarkable capability of acquiring tolerance to subsequent ischemic insult by establishing precautionary self-protective mechanism. Understanding this endogenous mechanism would reveal novel and effective neuroprotective targets for ischemic brain injury. Our previous study has implied that telomerase reverse transcriptase (TERT) is associated with IPC-induced tolerance.

Objective: The purpose of this study was to evaluate the feasibility and safety of myocardial biopsy using a new approach, the Liwen procedure.

Background: Myocardial biopsy is essential when other methods could not differentiate other etiologies from hypertrophic obstructive cardiomyopathy (HOCM). Our previous work using intramyocardial radiofrequency ablation for hypertrophic obstructive cardiomyopathy (Liwen procedure) may provide another approach to obtain the myocardial samples.

Objective: To explore the reasonable and effective enteral nutrition regimen for children with abdominal Henoch-Schönlein purpura (HSP).

Methods: A retrospective analysis was performed on the medical data of children with abdominal HSP who were hospitalized from August 2013 to August 2018. According to the starting time of enteral nutrition after abdominal pain relief, the children were divided into three groups: < 24 hours (=68), 24-48 hours (=64), and 48-72 hours (=60).

Since human coronavirus (HCoV)-like particles were detected in the stool specimens of acute gastroenteritis and necrotizing enterocolitis children with electron microscopy, the relationship between HCoV and the pediatric gastrointestinal illness had been recognized. In recent years, the overall detection rates have been low and have varied by region. HCoVs have not been considered as the major pathogens in pediatric acute gastroenteritis.

We derive the analytical formula of the energy weight of each orbital angular momentum (OAM) mode of twisted Gaussian Schell-model (TGSM) beams propagating in weak turbulent atmosphere. The evolution of its OAM spectrum is studied by numerical calculation. Our results show that the OAM spectrum of a TGSM beam changes with the beam propagating in turbulent atmosphere, which is completely different from that of the TGSM beam propagating in free space.

The cross-talk among different orbital angular momentum (OAM) modes induced by the turbulent atmosphere is a challenging effect commonly occurring in OAM-based free-space optical (FSO) communication. The aim of this study is to propose a simple method to reduce the crosstalk and demonstrate its effect by analytical derivation and numerical simulation. It is found that the crosstalk is largely reduced by using a focusing mirror.

Article Synopsis
  • The study investigates the genotype-phenotype relationship in hypertrophic cardiomyopathy (HCM) in three Chinese families, focusing on mutations in the ACTC1 and MYBPC3 genes.
  • Clinical examinations and advanced genetic analysis revealed two specific variants—ACTC1-D26N and MYBPC3-R215C—linked to HCM, with ACTC1-D26N being a likely pathogenic mutation.
  • Findings suggest that while ACTC1-D26N leads to non-obstructive HCM and specific heart patterns, MYBPC3-R215C's role as a genetic modifier is still uncertain.
