In this editorial, we have taken an in-depth look at the article published by Wan . The study showed that preconditioning mesenchymal stem cells (MSCs) protected them against programmed cell death, and increased their survival rate and therapeutic potential. Autophagy, a type of programmed cell death, is a major intracellular degradation and recycling pathway that is crucial for maintaining cellular homeostasis, self-renewal, and pluripotency.

- - Salt stress impacts plant growth and triggers complex molecular responses, including alternative splicing (AS), which helps plants adapt to the environment, particularly in a unique cliff-dwelling species from the Taihang Mountains.
- - Using RNA sequencing (RNA-seq), researchers identified differentially expressed genes (DEGs) and found two types of AS—skipped exons (SE) and mutually exclusive exons (MXE)—that were enriched in important biological pathways related to protein phosphorylation, carbohydrate metabolism, and hormone signaling.
- - The study revealed that while both species use protein phosphorylation to cope with salt stress, they show distinct responses and adaptive divergence, suggesting different evolutionary pathways for tolerance in these mountain-dwelling plants.

This article takes the concrete pavement of Xiamen Xiang'an New Airport as an example and uses a three-dimensional (3D) humidity simulation program for cement concrete pavement to study the evolution behavior of the early stage humidity field of the pavement in a humid and hot climate environment. The results indicate that the evolution law of the humidity field of the concrete pavement slab was consistent with the environmental field, presenting a 24 h periodic variation.

- The study focused on plants from the Taihang Mountains in China and their unique scent profiles, demonstrating that these cliff plants release distinctive aromatics.
- A comparative metabolic analysis revealed significant differences in the metabolic profiles of wild versus transplant flowers, emphasizing variations particularly among different flower groups.
- Key aromatic compounds identified included eugenol and chlorogenic, which were mainly linked to environmental temperature changes, showcasing their importance in the plants' adaptation to their ecosystem.
Objectives: This study aims to investigate the prevalence and antibiogram of and methicillin-resistance (MRSA) in rabbits, rabbit handlers, and rabbitry environments in Terengganu.
Materials And Methods: Swab samples from 183 rabbits (183 oral and 183 ear swabs), 45 rabbit handlers (45 oral and 45 nasal), and environmental ( = 180) samples from rabbitries were collected from 10 rabbit farms in Terengganu. The associated isolates from the swabs were isolated using phenotypic microbiology tests.
COVID-19 patients with comorbidities such as hypertension or heart failure (HF) are associated with poor clinical outcomes. The cellular distribution of Angiotensin-converting enzyme 2 (ACE2), the critical enzyme for SARS-CoV-2 infection, in the human heart is unknown. We explore the underlying mechanism that leads to increased susceptibility to SARS-CoV-2 in patients with cardiovascular diseases and patients of cardiac dysfunction have increased risk of multi-organ injury compared with patients of normal cardiac function.

- COVID-19 patients with pre-existing conditions like hypertension and heart failure face worse health outcomes, and ACE2, a key enzyme for virus entry, is found in various heart cell types, including cardiomyocytes.* -
- By analyzing single-cell RNA sequencing data, researchers found that in failing hearts, the number of ACE2-positive cardiomyocytes and their expression levels of ACE2 significantly increase, suggesting a potential link to heart failure progression.* -
- The study revealed that ACE2 expression in cardiomyocytes correlates with increased levels of brain natriuretic peptides and is associated with a higher risk of severe outcomes and mortality in COVID-19 patients, indicating that ACE2+ cells may be more susceptible to viral infection.*
Shih is an endemic and endangered genus restricted to the Taihang Mountains that has important ornamental and economic value. According to the Flora Reipublicae Popularis Sinicae (FRPS, Chinese version), this genus contains two species ( and ), whereas in the (English version) only one species is present. The interspecific phylogenetic relationship remains unclear and undefined, which might primarily be due to the lack of specific molecular markers for phylogenetic analysis.

- - Hair is vital for maintaining body temperature and mental health, but many suffer from hair loss with few effective regrowth solutions available.
- - Researchers found that small molecules like α-ketoglutarate, α-ketobutyrate, rapamycin, and metformin can stimulate dormant hair follicles to start growing hair by activating autophagy, a cellular process.
- - The study shows that stimulating autophagy can help trigger hair regeneration, particularly in aging mice, indicating potential new treatments for hair loss in humans.
Based on the three datasets from 1980s, 2010 and 2015 in Guangdong Province, we analyzed the spatial and temporal variations of soil pH in farmlands in different regions of Guangdong Province and analyzed the driving factors for such variations. The results showed that the spatial distribution of soil pH in Guangdong Province changed significantly in different periods. During 1980s to 2010, soil pH showed an acidification trend with a decline of 0.

November 2017
Iron oxide is the main form of iron element existing in the soil. In subtropical areas, the high-content iron oxide constitutes the soil's important coloring components, or its mineral substances, such as goethite and hematite, making the soil color apparently different from that in other climatic zones. The present paper, with the Pearl River Delta, a typical subtropical area, as illustration, and through analysis of the correlation between different spectral forms and the content of soil iron oxide, created inversion models of soil iron oxide by extracting characteristic spectral bands.

- Heavy metals, like cadmium (Cd), are significant pollutants in soil, impacting agriculture and human health, necessitating effective prediction methods for their distribution.
- A study in Guangdong province analyzed 1000 soil profiles, using 900 samples to train and 100 for validation, comparing multiple GIS interpolation methods including Cubist, which outperformed the others in predicting soil Cd concentration across various resolutions.
- The findings indicated that soil Cd levels were largely influenced by regional parent material properties, with higher concentrations primarily found in Carboniferous and Quaternary regions.
As a popular ornamental flower, potted lily is an important object of lily breeding. Paclobutrazol, a chemical growth retardation compound, is often used to dwarf plant in producing potted lilies. However, in recent years, the plants with inherited dwarf traits by using genetic engineer breeding technology are being developed.

- Orobanche aegyptiaca, a harmful weed, significantly damages agriculture and poses economic threats, prompting research into control methods.
- The study tested three lily cultivars for their ability to induce germination of O. aegyptiaca seeds, finding that parts like bulbs and leaf scales were particularly effective in triggering 'suicidal germination.'
- Results suggest that lilies could serve as trap crops or be processed into natural herbicides, providing an innovative approach to manage this parasitic weed in farming.
[Spatiotemporal variation of soil pH in Guangdong Province of China in past 30 years].
Ying Yong Sheng Tai Xue Bao
February 2011
Based on the 1980s' soil inventory data and the 2002-2007 soil pH data of Guangdong Province, the spatiotemporal variation of soil pH in the Province in past 30 years was studied. In the study period, the spatial distribution pattern of soil pH in the Province had less change (mainly acidic), except that in Pearl River Delta and parts of Qingyuan and Shaoguan (weak alkaline). The overall variation of soil pH was represented as acidification, with the average pH value changed from 5.
