Effects of phosphorus application on yield, quality and phosphorus use efficiency of edible sweetpotato: A case study of Xushu 32.

To explore the appropriate amount of phosphorus (P) fertilizer and improve economic yield and P use efficiency of edible sweetpotato, we took Xushu 32 as an example and compared the effects of different P application rates on yield, quality, P accumulation and P use efficiency of edible sweetpotato based on a two-year field experiment (soil available P content was 31.70 mg·kg) from 2018 to 2019. There were five P application levels (PO), including 0 (P), 25 (P), 50 (P), 75 (P) and 100 kg·hm(P).

Efficacy and safety of pulsatile gonadotropin-releasing hormone therapy in patients with congenital hypogonadotropic hypogonadism: a multicentre clinical study.

Background: Pulsatile gonadotropin-releasing hormone (GnRH) therapy may restore function of the hypothalamus-pituitary-gonad axis and induce spermatogenesis in male patients with congenital hypogonadotropic hypogonadism (CHH). The study sought to test the reliability of a newly developed Innopump hormone pump, and to confirm the efficacy and safety of pulsatile GnRH therapy (by Innopump hormone pump) in CHH patients.

Methods: From November 2017 to November 2018, 28 male patients with CHH were treated with pulsatile GnRH at Peking Union Medical College Hospital, Beijing Chaoyang Hospital, and Shandong Provincial Hospital.

A treadmill exercise reactivates the signaling of the mammalian target of rapamycin (mTor) in the skeletal muscles of starved mice.

It has been well established that a starvation-induced decrease in insulin/IGF-I and serum amino acids effectively suppresses the mammalian target of rapamycin (mTor) signaling to induce autophagy, which is a major degradative cellular pathway in skeletal muscles. In this study, we investigated the systematic effects of exercise on the mTor signaling of skeletal muscles. Wild type C57BL/6J mice were starved for 24h under synchronous autophagy induction conditions.

Objectifying research on special region corresponding to five internal organs in colour inspections of Chinese medicine.

Objective: To study the differences in a special region (SR) corresponding to five internal organs between the young and the elderly and to verify the effectiveness of a developed system for objectifying research in colour inspections of Chinese medicine (CICM).

Methods: An image acquisition device imitating daylight to meet the requirement of CICM was designed. Image processing software based on CICM theory was developed.

[Mercury pollution in cricket in different biotopes suffering from pollution by zinc smelting].

Total mercury contents in cricket bodies were studied in different biotopes in the surrounding of Huludao Zinc Plant to discuss the mercury distribution characteristics in cricket and to reveal the effects of environmental mercury accumulation in the short life-cycle insects through comparing cricket with other insect species. The average mercury content in cricket was 0.081 mg x kg(-1) and much higher than those in the control sites (0.

Ferulic acid induces mammalian target of rapamycin inactivation in cultured mammalian cells.

Ferulic acid (FA), a naturally occurring polyphenol abundant in vegetables and rice bran, is known to possess a potent antioxidant activity, thereby protecting cells from oxidative stress. In the present study, we show that in addition to its known anti-oxidant activity, ferulic acid exerts substantial inhibitory activity on cellular mammalian target of rapamycin (mTor)-signaling pathways. In HeLa cells and mouse primary hepatocytes cultured with conventional nutrient-rich media, ferulic acid (1 mM) elicited dephosphorylation of S6 kinase and its substrate ribosomal S6.

Interleukin-11 links oxidative stress and compensatory proliferation.

Apoptotic cells can stimulate the compensatory proliferation of surrounding cells to maintain tissue homeostasis. Although oxidative stress is associated with apoptosis and necrosis, whether it contributes to compensatory proliferation is unknown. Here, we showed that interleukin-11 (IL-11), a member of the IL-6 family of proinflammatory cytokines, was produced by cells in an oxidative stress-dependent manner.

Liver autophagy contributes to the maintenance of blood glucose and amino acid levels.

Both anabolism and catabolism of the amino acids released by starvation-induced autophagy are essential for cell survival, but their actual metabolic contributions in adult animals are poorly understood. Herein, we report that, in mice, liver autophagy makes a significant contribution to the maintenance of blood glucose by converting amino acids to glucose via gluconeogenesis. Under a synchronous fasting-initiation regimen, autophagy was induced concomitantly with a fall in plasma insulin in the presence of stable glucagon levels, resulting in a robust amino acid release.

[Mercury contents and distribution characteristics in cicadae].

Total mercury contents of cicadae bodies, wings and exuviaes were studied in Huludao City to discuss mercury distribution characteristics in cicadae and to reveal the environmental mercury accumulation effects in the long life-cycle insects through comparing cicadae with other insect species. The average mercury contents of cicadae bodies were 2. 64 mg x kg(-1) and much higher than those in the contrast sites (1.

Bioaccumulation of total and methyl mercury in three earthworm species (Drawida sp., Allolobophora sp., and Limnodrilus sp.).

We determined total and methyl mercury contents in soil, three earthworm species and their vomitus to study the species-specific differences of mercury bioconcentration in Huludao City, a heavily polluted region by chlor-alkali and nonferrous metal smelting industry in Liaoning Province, northeast China. Total and methyl mercury contents were 7.20 mg/kg and 6.

Sphingosine 1-phosphate protects rat liver sinusoidal endothelial cells from ethanol-induced apoptosis: Role of intracellular calcium and nitric oxide.

In alcoholic liver disease, ethanol-induced damage to sinusoidal endothelial cells (SECs) appears to be important in the progression of liver damage. However, little is known about the mechanisms responsible for protection of SECs against ethanol-induced injury. To elucidate the role of sphingosine 1-phosphate (S1P), which is stored in platelets and may be released from them on their activation, we investigated the effect of S1P on rat liver SECs in primary culture.
