Article Synopsis
  • Wild apple trees (Malus sieversii), crucial for apple cultivation, are declining in their natural habitats in China, necessitating artificial breeding methods to support their regeneration.
  • This study analyzed the effects of varying nitrogen and phosphorus nutrient additions on the growth traits of wild apple saplings over four years, demonstrating that nitrogen significantly boosts several growth metrics, while phosphorus mainly affects stem growth.
  • Optimal combinations of nitrogen and phosphorus positively influenced stem growth, but low concentrations of nitrogen with phosphorus had detrimental effects, indicating the need for careful management of nutrient levels to support sapling development.

In the quality evaluation of public sports training, the selected indicators are not comprehensive, resulting in some errors in the results of quality evaluation. Therefore, this paper designs a public sports training quality evaluation method based on the deep learning model of global topology optimization. Determine the basic principles of public sports training quality evaluation, determine the human coordinate points of public sports training by determining the basic section and basic axis of human training, and extract the data of public sports training quality evaluation.

This study investigates the efficacy of benign prostatic hyperplasia (BPH) treatment by prostate transurethral enucleation using a 2-μm laser. A total of 107 patients with BPH were treated by prostate transurethral enucleation using a RevoLix 2-μm laser surgery system. Bleeding volume, operation time, catheterization time, voiding situation, maximum urinary flow rate, and hospital stay were observed.

PM10 samples were collected at Huli (industrial zone) and Dadeng Island in Xiamen from December 2008 to March 2009. Nineteen polycyclic aromatic hydrocarbons (PAHs) during haze and non-haze periods were determined by GC/MS. Combined with the meteorological data, the differences of chemical composition and source of PAHs were compared.

Article Synopsis
  • A study involving 100 male rats divided into four groups examined the effects of different zinc (Zn) diets over 5 weeks, including adequate, deficient, overdose, and pair-fed diets.
  • The Zn-deficient group showed reduced body and femur weights, along with decreased activity of alkaline phosphatase (ALP) and lower serum calcium levels, while the Zn-overdose group exhibited increases in body and femur weights and elevated Zn levels in the liver and femur.
  • The research concluded that dietary Zn significantly impacts growth, bone metabolism, and the expression of insulin-like growth factor-I (IGF-I) and ALP in growing male rats, highlighting the importance of Zn for proper physiological development.

The effect of sodium dodecylbenzene sulfonate (SDBS) on the volatilization of 17 organochlorine pesticides (OCPs) from still artificial seawater has been examined. The results show that SDBS at low concentration can retard the volatilization of OCPs compared to "clean" surface. The retarding influence is more pronounced for high level of SDBS than it is for low level of SDBS.

Zinc deficiency induces a striking reduction of food intake in animals. To elucidate the mechanisms for this effect, two studies were connectedly conducted to determine the effects of peripheral administration of zinc on food intake in rats fed the zinc-adequate or zinc-deficient diets for a 3-week period. In study 1, two groups of male Sprague-Dawley rats were provided diets made either adequate (ZA; 38.

Background: This study evaluated effects of zinc on the hepatic lipid peroxidation, antioxidant components and mRNA expression levels in rats.

Methods: Three diets with different Zn levels including Zn adequacy (ZA; 34.50 mg/kg, control), Zn deficiency (ZD; 3.

Distribution and properties of the main digestive enzymes including protease and amylase, from stomach, pancreas and the anterior, middle and posterior intestine of the adult red-eared slider turtle Trachemys scripta elegans were studied at various pHs and temperatures. The optimum temperature and pH for protease in stomach, pancreas and the anterior, middle and posterior intestine were 40 degrees C, 2.5; 50 degrees C, 8.

Zinc (Zn) is an essential trace element required for human beings and animals. This divalent cation is involved in many physiological functions, including immune and antioxidant function, growth, and reproduction. Deficiency of Zn produces several pathological disorders and abnormalities in its metabolism, such as anorexia, weight loss, poor efficiency, and growth retardation.

Objective: The present study simultaneously investigated the effects of different zinc (Zn) levels on the growth performance and relative biochemical parameters in growing rats and analyzed the molecular mechanism of zinc influencing food intake.

Methods: Three diets with different Zn levels--Zn adequate (ZA; 35.94 mg/kg, control), Zn deficient (ZD; 3.
