Suprathreshold Water Spray Stimulus Enhances Plant Defenses against Biotic Stresses in Tomato.

Mechanical stimuli can affect plant growth, development, and defenses. The role of water spray stimulation, as a prevalent mechanical stimulus in the environment, in crop growth and defense cannot be overlooked. In this study, the effects of water spray on tomato plant growth and defense against the chewing herbivore and necrotrophic fungus were investigated.

Clinical research progress on acupuncture for the treatment of otogenic vertigo.

Otogenic vertigo is a common disorder that affects the vestibular system, which often results in considerable discomfort and impaired daily functioning. Traditional Chinese medicine (TCM), including acupuncture and moxibustion, has been historically utilized to manage the symptoms of vertigo. However, the effectiveness and methodology of these treatments have rarely been investigated in the medical literature.

Pentacyclic triterpene-amino acid derivatives induced apoptosis and autophagy in tumor cells, affected the JNK and PI3K/AKT/mTOR pathway.

A series of pentacyclic triterpene-amino acid derivatives were synthesized and tested for anti-proliferative activity. The results showed that most of the target compounds had good anti-proliferative activity. 2c did not contain protecting groups and hydrochloride, had excellent cytotoxicity, so it had been selected for further study in the mechanism of action in T24 cells.

MicroRNA-141-3p inhibits retinal neovascularization and retinal ganglion cell apoptosis in glaucoma mice through the inactivation of Docking protein 5-dependent mitogen-activated protein kinase signaling pathway.

Retinal neovascularization occurs in various ocular disorders including proliferative diabetic retinopathy and secondary neovascular glaucoma, resulting in blindness. This paper aims to investigate the effect of microRNA-141-3p (miR-141-3p) on retinal neovascularization and retinal ganglion cells (RGCs) in glaucoma mice through the Docking protein 5 (DOK5)-mediated mitogen-activated protein kinase (MAPK) signaling pathway. Chip retrieval and difference analysis were used for the potential mechanism of miR-141-3p on glaucoma.

Role of microRNA-29a in the development of diabetic retinopathy by targeting AGT gene in a rat model.

Objectives: This study intends to explore the role of microRNA-29a (miRNA-29a) in the development of diabetic retinopathy by targeting AGT gene in a rat model.

Methods: Fifty-six DR rat models were established and divided into 7 groups (with 8 rats in each group): the model group, the miRNA-29a group, the miRNA-29a knockdown group, the negative control (NC) group, the AGT group, the miRNA-29a+AGT group, and the miRNA-29a knockdown+AGT group respectively, while 8 normal rats were selected as the normal group. The qRT-PCR was used to detect the expression of miRNA-29a and AGT mRNA.

[Effects of continuous cropping of wheat and alfalfa on soil enzyme activities and nutrients].

Based on a long-term rotation and fertilization experiment in Changwu, Shaanxi, China, we determined the enzymatic activities and nutrients in soils after 27 years continuous cropping of alfalfa and wheat, respectively. The activities of invertase, urease and phosphatase were not affected by fertilization treatment within each cropping system, but they were significantly higher in the alfalfa continuous cropping system than in the wheat continuous cropping system under each fertilization treatment. The activity of hydrogen peroxidase was not affected by the type of cropping system or fertilization treatment.

[Drug dynamics research of salvia miltiorrhiza in rabbit plasma and aqueous humor after intravenous injection].

Objectives: To assess the permeability of Danshensu at blood-ocular barrier and its characteristics of pharmacokinetics by respectively measuring the concentrations of Danshensu in blood plasma and aqueous humor of the rabbit with the high performance liquid chromatography(HPLC).

Methods: It was an experimental study. Seventy-two white rabbits were split into three groups: control group (6 rabbits), plasma group (6 rabbits) and aqueous humor group (60 rabbits).

In vitro evaluation of enhancing effect of borneol on transcorneal permeation of compounds with different hydrophilicities and molecular sizes.

To investigate the enhancing effect of borneol on transcorneal permeation of compounds with different hydrophilicities and molecular sizes. Six compounds, namely rhodamine B, sodium-fluorescein, fluorescein isothiocyanate (FITC) dextrans of 4, 10, 20 and 40 kDa were selected as model drugs. Permeation studies were performed using excised cornea of rabbits by a Franz-type diffusion apparatus.

Preventive effect of danshensu on selenite-induced cataractogenesis in cultured rat lens.

Background: To investigate the preventive effect of danshensu on the selenite-induced opacification of cultured rat lenses.

Methods: Isolated lens were divided into three groups with eight lenses in each group. Group I: lenses were incubated with M199 medium alone; Group II: incubated in M199 containing 200 µmol/L sodium selenite; Group III: incubated in M199 containing 200 µmol/L sodium selenite and 500 µmol/L danshensu.

[Clinical features of the nephrotic syndrome associated with ichthyosis vulgaris and analysis of related gene mutation].

Objective: To study clinical features of 3 children who presented with nephrotic syndrome (NS) associated with ichthyosis vulgaris (IV), and to detect relationship between NS associated with IV in patients and FLG gene or NPHS2 gene.

Method: Clinical and kidney pathological data of the 3 patients were analyzed and progress of pathologic damage in the patient kidney was observed through repeated percutaneous renal biopsy. Using polymerase chain reaction-single strand conformation polymorphism and DNA sequencing, the diversity of the expression of NPHS2 gene in the 3 patients were analyzed, and FLG gene in the 3 patients and parts of their family members with IV was detected.

Sedimentation retention basin utilization for best management practice.

Approaches to the artificial impoundment and theoretical design of sedimentation retention basin are reviewed with particular attention to best management practice (BMP) to control agriculture and surface runoff. Sediments retention basins are the small version of farm pond used where a criteria of farm pond is not met. Such basin traps the pollutants and suspended solids prior to entry into streams and lakes.
