ABA exerts a promotive effect on the early process of somatic embryogenesis in Quercus aliena Bl.

Quercus aliena, a native Chinese tree species, is significant in industry and landscaping. However, it is traditionally propagated by seeds with many limitations, such as pest infestations, seed yield and quality. Thus, this study firstly introduces a somatic embryogenesis (SE) system for Q.

Oral mucosal diseases and psychosocial factors: progress in related neurobiological mechanisms.

The aetiology of oral mucosal diseases, such as recurrent aphthous ulcer (RAU), oral lichen planus (OLP) and burning mouth syndrome (BMS), involves many factors, and it remains difficult for clinicians to effectively relieve disease symptoms and formulate coping strategies. With the rapid development of psychology, the role of mental and psychological factors in RAU, OLP and BMS has gradually attracted researchers attention, but the specific mechanism has not been completely determined. This narrative review describes the potential neurobiological mechanism of oral mucosal diseases and detailed psychological factors after introducing relevant research into psychological factors and oral mucosal diseases.

Repairing Effect and Mechanism of Hydroxysafflor Yellow A and Sodium Hyaluronate for Knee Osteoarthritis in Rabbits.

Context: KOA characterized by recurrent joint pain and progressive joint dysfunction. Is the present clinical common chronic progressive degenerative osteoarthropathy, how long the disease is difficult to cure and easy to relapse. Exploring new therapeutic approaches and mechanisms is important for the treatment of KOA.

Traits variation of acorns and cupules during maturation process in Quercus variabilis and Quercus aliena.

Quercus variabilis and Quercus aliena are two native tree species in China, which have similar habitats, and their regeneration mainly depends on acorn dispersal. This study analyzed the contents of water, soluble sugar, starch, soluble protein, and total phenolics in acorns and cupules during the whole development process to explore the difference between species. Thereinto, starch and total phenol occupied the dominant roles as their high contents.

Anthocyanin Biosynthesis Associated with Natural Variation in Autumn Leaf Coloration in Accessions.

is an economically important tree species and one of the dominant native oak species in China. Although its leaves typically turn yellow in autumn, we observed natural variants with red leaves. It is important to understand the mechanisms involved in leaf color variation in this species.

Effects of silkworm excrement and water management on the accumulation of Cd and As in different varieties of rice and an assessment of their health risk.

Rice (Oryza sativa L.) consumption represents a major route for the exposure to cadmium (Cd) and arsenic (As) in many countries. Two varieties of rice that were grown in soils contaminated with Cd and As were evaluated for the accumulation of these toxins in rice grains and the risks of exposure of local residents to Cd and As when treated with different amounts of silkworm excrement and types of water management.

Effects of a novel biflavonoid of Lonicera japonica flower buds on modulating apoptosis under different oxidative conditions in hepatoma cells.

Background: In our previous work, we purified a novel biflavonoid named Japoflavone D (JFD) from Lonicera japonica flower buds. Biflavonoids are chemical compounds characterized by their high levels of antioxidative activity.

Purpose: The present study aimed to investigate the function and molecular mechanism of JFD under different oxidative conditions in hepatoma cells.

A new meroterpenoid functions as an anti-tumor agent in hepatoma cells by downregulating mTOR activation and inhibiting EMT.

Liver cancer, also known as primary liver cancer, is cancer that starts in the liver. JNU-144, a new meroterpenoid purified from Lithospermum erythrorhizon, has exhibited promising anticancer activity; however, the molecular mechanisms of action of JNU-144 on malignant cells remain unclear. Our studies revealed that JNU-144 suppressed cell viability and proliferation in hepatoma cells by downregulating mTOR activation.

Interaction of renin-angiotensin system and adenosine monophosphate-activated protein kinase signaling pathway in renal carcinogenesis of uninephrectomized rats.

Renin-angiotensin system and adenosine monophosphate-activated protein kinase signaling pathway both play important roles in carcinogenesis, but the interplay of renin-angiotensin system and adenosine monophosphate-activated protein kinase in carcinogenesis is not clear. In this study, we researched the interaction of renin-angiotensin system and adenosine monophosphate-activated protein kinase in renal carcinogenesis of uninephrectomized rats. A total of 96 rats were stratified into four groups: sham, uninephrectomized, and uninephrectomized treated with angiotensin-converting enzyme inhibitor or angiotensin receptor blocker.

Cross-talk between AMP-activated protein kinase and renin-angiotensin system in uninephrectomised rats.

Introduction: The renal renin-angiotensin system (RAS) and the ultrasensitive energy sensor AMP-activated protein kinase (AMPK) have been implicated in normal and aberrant states of the kidney, but interaction between the RAS and AMPK remains unknown.

Methods: Ninety-six rats were stratified into four groups: sham, uninephrectomised, uninephrectomised rats treated with the angiotensin-converting enzyme inhibitor lisinopril or the angiotensin receptor blocker losartan. Histopathological examination at 9 months post-operation and biochemical measurements at 3, 6 and 9 months were performed for changes in renal structure and function.

Spontaneous remission of membranous glomerulonephritis with successful fetal outcome: A case report and literature review.

Membranous glomerulonephritis (MGN) represents an immunologically mediated disease characterized by deposition of immune complexes in the glomerular subepithelial space. Persistent proteinuria at diagnosis predicts poor prognosis. Pregnancy with MGN is a risk of fetal loss and may worsen maternal renal function.

Cytokine-induced killer cells efficiently kill stem-like cancer cells of nasopharyngeal carcinoma via the NKG2D-ligands recognition.

Cancer stem cells (CSCs) are considered to be the root cause for cancer treatment failure. Thus, there remains an urgent need for more potent and safer therapies against CSCs for curing cancer. In this study, the antitumor activity of cytokine-induced killer (CIK) cells against putative CSCs of nasopharyngeal carcinoma (NPC) was fully evaluated in vitro and in vivo.

Five COX-2 gene polymorphisms and risk of breast cancer: an updated meta-analysis based on 19 case-control studies.

The correlationship between COX-2 gene polymorphisms and breast cancer has been wildly studied, but the results remain controversial. Hence, the present meta-analysis aimed to investigate the association between COX-2 SNPs (rs5275, rs20417, rs689466, rs5277, rs2206593) and risk of breast cancer. Data were collected from PubMed, Embase and China National Knowledge Infrastructure.
