Patterns and Internal Stability of Carbon, Nitrogen, and Phosphorus in Soils and Soil Microbial Biomass in Terrestrial Ecosystems in China: A Data Synthesis
spatial pattern C:N:P vegetation types nutrient limitation homeostasis
2023/12/11
Inspired by the strict constraint ratio (relatively low variability) between carbon (C), nitrogen (N), and phosphorus (P) in global soils and soil microbial biomass, our study explores the biogeograph...
External and Internal Reshaping of Plant Thermomorphogenesis
circadian clock interorgan communication photoperiod temperature sensing thermomorphogenesis
2023/12/4
Plants dynamically adapt to changing temperatures to ensure propagation and reproductive success, among which morphogenic responses to warm temperatures have been extensively studied in recent years. ...
New microscope technique reveals internal structure of live embryos（图）
New microscope technique internal structure live embryos
2017/9/4
University of Illinois researchers have developed a way to produce 3-D images of live embryos in cattle that could help determine embryo viability before in vitro fertilization in humans.Infertility c...
Trapping of internal and external feeding stored grain beetle pests with two types of pitfall traps: a two-year field study
Coleoptera stored-product pests grain
2016/2/22
Pitfall trapping studies are available for particular stored grain pest species. In small farms, the stored grain pest control strategy is rarely species-specific but is often “pest ecological-group-s...
A high incidence of leukocyte chimerism (60,XX/60,XY) in single born heifers culled due to underdevelopment of internal reproductive tracts
cattle disorders of sex development freemartinism
2015/7/2
Freemartinism, a primary disorder of sex development (DSD) in cattle, is associated with leukocyte chimerism (60,XX/60,XY). The diagnosis of DSD is easy if it is known that a heifer with abnormally de...
Interaction between housing system and genotype in relation to internal and external egg quality parameters
laying hen conventional cage enriched cage litter genotype egg physical measurements pore density
2015/6/9
The effect of three housing systems (conventional cages, enriched cages and litter) on egg quality parameters was evaluated in two experiments with four brown laying strains ISA Brown, Hisex Brown, Bo...
A new internal standard for HPLC assay of conjugated linoleic acid in animal tissues and milk
sorbic acid internal standard CLA isomers HPLC photodiode array detection biological samples
2015/6/9
A new method for the quantification of underivatized conjugated linoleic acid (CLA) isomers and CLA-metabolites by silver ion liquid chromatography (Ag+-HPLC) with photodiode array detection (DAD) is ...
Relationships between external and internal udder measurements and the linear scores for udder morphology traits in dairy sheep
Tsigai Improved Walachian Lacaune ewe mammary gland cistern
2015/6/2
Udder morphology traits were measured and subjectively assessed by the use of linear scores in 266 ewes of Tsigai (T), Improved Walachian (IW) and Lacaune (LC) dairy breeds. Animals were recorded repe...
Development of Polymerase Chain Reaction assays with host-specific internal controls for Chlamydophila abortus
Chlamydophila abortus internal control PCR
2015/5/25
Therefore, culture-independent detection methods such as the polymerase chain reaction
are increasingly important and needed. The aim of this study was to develop a polymerase chain reaction assay
...
A simplified duplex real-time PCR incorporating TaqMan minor groove binder (MGB) probes and an exogenous internal positive control for the simultaneous detection of Mycoplasma gallisepticum and Mycoplasma synoviae cultures
avian Mycoplasma spp duplex real-time PCR
2015/5/25
Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most pathogenic and
economically important mycoplasma pathogens that infect chickens. The development of rapid and innovative
mol...
