Article Synopsis
  • A study investigated the impact of auxin treatment on calcium transport in apple fruit stalks, finding that different auxin concentrations affected calcium content and fruit quality.
  • Results showed a significant decrease in total calcium in the stalk, alongside a 30% increase in calcium content in the fruit, suggesting auxin promotes better fruit nutrition.
  • The research utilized the TOPSIS method to rank fruit quality based on auxin treatments, highlighting the potential for improved calcium efficiency in bagged apples and setting the stage for future investigations.

Background: Fear of childbirth is a common concern in pregnant women and their spouses due to the unpredictability of the process and outcome of a delivery, which results in adverse effects on mental health, birth outcomes and family intimacy. However, there is a lack of studies that explore the influencing factors of fear of childbirth among expectant couples from a dyadic perspective. The aim of this study is to explore the correlation of dyadic coping, resilience and fear of childbirth in pregnant couples and to construct an actor-partner interdependence model to verify dyadic effects.

Article Synopsis
  • - The study investigates how nitrogen (N) and potassium (K) interaction affects photosynthesis in apple rootstock M9T337 using hydroponics to analyze different nutrient conditions.
  • - High N with low K leads to a deficiency in K in both roots and leaves, creating an N/K imbalance that negatively impacts leaf photosynthesis through various limitations.
  • - Adjusting N levels under low K conditions can enhance protein distribution and improve the photosynthetic process by increasing key rates, suggesting that balancing N and K is crucial for optimal plant health.

Purpose: To evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) paired with cognitive training on cognitive function in Alzheimer's Disease (AD) patients.

Methods: PubMed, The Cochrane Library, Embase, CINAHL Complete (EBSCO), China National Knowledge Infrastructure (CNKI) and WanFang Database were searched. The risk of bias was appraised through the Cochrane collaboration tool.

To compare the therapeutic effect of less invasive surfactant administration (LISA) followed by synchronized nasal intermittent positive pressure ventilation (SNIPPV) and traditional intubate-Surfactant-Extubate (InSurE) strategy for the treatment of neonatal respiratory distress syndrome (NRDS). A single-center, non-randomized and single- blinded study Tertiary neonatal intensive care unit 89 infants enrolled were preterm with gestational age < 36 weeks and clinically diagnosed with neonatal RDS (NRDS) Interventions: 32 infants were assigned to the LISA + SNIPPV group and 57 infants to the InSurE + nCPAP group. No statistically significant differences were noted in the baseline characteristics of the enrolled infants.

Selenium (Se) can be absorbed by plants, thereby affects plant physiological activity, interferes gene expression, alters metabolite content and influences plant growth. However, the molecular mechanism underlying the plant response to Se remains unclear. In this study, apple plants were exposed to Se at concentrations of 0, 3, 6, 9, 12, 24, and 48 μM.

Background: Minimal change disease (MCD) is one of the most common primary glomerular disorders with high serum IgE levels. This study was aimed to investigate the clinical features of different serum IgE levels in pediatric MCD and evaluate the prognostic significance of serum IgE levels with regard to remission and relapse in pediatric cohort.

Methods: This study enrolled 142 new-onset children diagnosed with biopsy-proven MCD from January 2010 to December 2021 at the Jinling Hospital in Nanjing, China.

This paper reports observations and analysis of the Rb 3Π state. A total of 323 rovibrational term values spanning the range of the rotational quantum number = 7 through 77 and the vibrational quantum number = 2 through 23 (about 1/3 of the potential well depth) were measured using the optical-optical double resonance technique. The term values are simulated within a model of a piece-wise multi-parameter potential energy function based on the generalized splines.

Background: Problems exist in congenital syphilis (CS) diagnosis and no single test can be used to diagnose CS.

Objective: To know whether there exist differences of nested polymerase chain reaction (nPCR) sensitivity among four membrane protein DNA and of nPCR between two pairs of primers for Tpp47.

Methods: We collected 30 CS patients as a study group, and 20 cases admitted to hospital for other reasons as a control group.

Ro-vibrational term values of the 3(1)Σg (+) state of (85,85)Rb2 and (85,87)Rb2 and resolved fluorescence spectra to the A(1)Σu (+) state are recorded following optical-optical double resonance excitation. The experimental data are heavily perturbed, and as a result, the standard analysis based on Dunham series representation of the energy levels fails. The analysis is done via modeling the adiabatic potential function with the Rydberg-Klein-Rees potential constructed from the generalized smoothing spline interpolation of the vibrational energies Gv and rotational constants Bv.

Background: Diffusion-tensor imaging (DTI) can be used to investigate water diffusion in living tissue.

Objective: To investigate sequence and relationship of regional maturation in corpus callosum (CC) and internal capsule (IC) in preterm and term.

Methods: DTI was performed on 11 preterm infants at less than 37 weeks of corrected gestational age (group I), 21 preterm infants at equivalent-term (group II), 11 term infants during neonatal period (group III).

It has been reported that oligomeric procyanidins of lotus seedpod (LSOPC) is effective in the alleviation of Alzheimer's disease and diabetes through its antioxidant and insulin-potentiating activities. This study investigated the anti-glycative activity of LSOPC in a bovine serum albumin (BSA)-glucose model. The level of glycation and conformational alterations were assessed by specific fluorescence, Congo red binding assay and circular dichroism.

Objective: The prostate apoptosis response factor-4 (Par-4) gene was originally identified by differential screening for genes that are up-regulated when prostate cells are induced to undergo apoptosis. Par-4 was found to possess potent apoptotic activity in various cellular systems in response to numerous stimuli. The aim of this study was to explore the effects of small interfering RNA (siRNA) against Par-4 gene on the apoptosis of human bone marrow mesenchymal stem cells (hBMSCs) exposed to glutamate.

Neural cells undergo glutamate-induced apoptosis in ischaemic brain tissue, in which prostate apoptosis response-4 gene (Par-4) is involved. Human-bone mesenchymal stem cells can be utilized as an effective therapy for ischemic brain injury. In this study, we found that glutamate could induce apoptosis in human-bone mesenchymal stem cells, accompanied by increased expression of Par-4 gene and Smac release from mitochondria.

Objective: To investigate the effects of Par-4 gene silencing induced by siRNA on the expression of Smac gene, activity of caspase-3, and apoptosis of human bone marrow mesenchymal stem cells (hBMSCs).

Methods: Bone marrow was obtained from a healthy young man and hBMSCs were isolated and cultured. Two siRNAs (Par-4-siRNA-1 and -2) targeting Par-4 gene were chemically synthesized.
