A long-term fertilization field experiment was conducted to investigate the effect of nitrogen (N), phosphorus (P), and potassium (K) fertilizer on maize relative yield, yield-increasing effect and the changes of nutrients in yellow soil in Guizhou Province. Five fertilizer combinations were evaluated, including balanced fertilization (NPK) and nutrient deficiency treatments (N, NK, NP, and PK). The maize relative yield, contribution efficiency of N, P, K fertilizer application, sustainability index of soil N, P, K nutrients, and other indicators were measured...

As a kind of globally widely distributed soil microorganism, arbuscular mycorrhizal (AM) fungi form the symbiosis with the majority of land plants, which is important for plant nutrition and ecosystem functioning. Few vascular species are considered to be nonmycorrhizal, especially those within the families Amaranthaceae, Chenopodiaceae, Carophyllaceae and Brassicaceae. At present, the interactions between these non-host plants and AM fungi are few and scattered, lacking systematic summary. In this paper, the type of non-host plants, the reason of low mycotrophy, and the effect of AM network formed by neighbor plants on AM fungi colonization on the non-host, and the possible interaction between AM fungi and non-host, as well as the material exchange between plants and AM fungi and their possible ecological functions were reviewed in order to give some new ideas on the function of the nonmycorrhizal plants in the fragile ecosystems...

Soil organic carbon pool is an important component of terrestrial carbon pool. Soil organic carbon pool and its dynamic change have important influence on carbon cycle in terrestrial ecosystem. Soil organic carbon density (SOCD) is an important parameter of soil carbon storage, and it is also an important index to evaluate farmland soil quality. Accurate prediction of regional organic carbon density spatial distribution is of great significance to the development of precision agriculture. A total of 242 farmland soil samples collected from the Jianghan Plain were used to explore the effects of land use types on the spatial distribution of SOCD in plain areas...

BACKGROUND: Epilepsy is a central nervous system disorder (neurological disorder). Epileptic seizures are the result of excessive and abnormal cortical nerve cell electrical activity in the brain. Despite the development of more than 10 new antiepileptic drugs (AEDs) since the early 2000s, approximately a third of people with epilepsy remain resistant to pharmacotherapy, often requiring treatment with a combination of AEDs. In this review, we summarised the current evidence regarding rufinamide, a novel anticonvulsant medication, which, as a triazole derivative, is structurally unrelated to any other currently used anticonvulsant medication, when used as an add-on treatment for refractory epilepsy...

REVIEW
Carolyn Rabin
The aim of this review was to determine the impact of a cancer diagnosis and history on young adults' ability to initiate and maintain romantic relationships. MedLine and PsycInfo databases were used to identify articles that address dating, romantic relationships, or marriage among 18- to 45-year-old cancer survivors. Twenty-one relevant articles were identified. Findings indicate that young adult cancer survivors struggle with when/how to disclose their cancer history to potential partners, are delayed in initiating their first romantic relationships, have fewer romantic relationships than peers, and are less likely than peers to marry...

Trypanosoma evansi is a zoonotic parasite associated with high animal mortality that has gained importance due to its capacity to infect humans. Recently, some evidences have demonstrated that T. evansi infection causes severe genotoxic and cytotoxic damage in brain cells, contributing to the pathogenesis and clinical signs of the disease. In this sense, the aim of this study was to evaluate whether nerolidol-loaded in nanospheres, a natural compound with trypanocidal and neuroprotective effects, is able to protect the brain tissue from the cytotoxic and genotoxic effects found during T...

Trastuzumab is a standard treatment for HER2-positive (HER2+ ) breast cancer, but some patients are refractory to the therapy. MicroRNAs (miRNAs) have been used to predict therapeutic effects for various cancers, but whether miRNAs can serve as biomarkers for HER2+ metastatic breast cancer (MBC) patients remains unclear. Using miRNA microarray, we identify 13 differentially expressed miRNAs in the serum of HER2+ MBC patients with distinct response to trastuzumab, and four miRNAs are selected to construct a signature to predict survival using LASSO model...

Fabrication of composite scaffolds is one of the strategies proposed to enhance the functionality of tissue engineered scaffolds for improved tissue regeneration. By combining multiple elements together, unique biomimetic scaffolds with desirable physical and mechanical properties can be tailored for tissue-specific applications. Despite having a highly porous structure, the utility of electrospun fibers (EF) as scaffold is usually hampered by their insufficient mechanical strength. In this study, we attempted to produce a mechanically competent scaffold with cell-guiding ability by fabricating aligned PLGA fibers on decellularized human amniotic membrane (HAM), known to possess favorable tensile and wound healing properties...

We report spontaneous hemodynamic activity termed "Spontaneous BOLD Waves" (SBWs) detected by BOLD fMRI in Sprague-Dawley rats under medetomidine anesthesia. These SBWs, which lasted several minutes, were observed in cortex, thalamus and hippocampus. The SBWs' correlates were undetectable in electrophysiological recordings, suggesting an exclusive gliovascular phenomenon dissociated from neuronal activity. SBWs were insensitive to the NMDA receptors antagonist MK-801 but were inhibited by the α1-adrenoceptor blocker prazosin...

A new species of pygmy squid, Idiosepius hallami n. sp., is described from eastern Australia. It differs from I. notoides Berry, 1921 and I. pygmaeus Steenstrup, 1881 (also found in Australian waters) in a number of traits, including the number of club suckers, shape of the funnel-mantle locking apparatus and the modification of the male hectocotylus. Mitochondrial DNA markers (12S rRNA, 16S rRNA and cytochrome c oxidase subunit 1) indicate that it is also distinct on a molecular level. The new Australian species is also recognised as the taxon from Stradbroke I...

With the exception of polycopids, Mesozoic myodocopid ostracods are regarded as uncommon in the fossil record. They are known from a few localities in the Tethys, and most of them are considered to be pelagic forms. However, a relatively rich and taxonomically diverse material is derived from Hungarian sections; these represent various formations deposited during the Triassic to Cretaceous.The aim of this study is to summarize the current knowledge of Mesozoic myodocopids and to provide new information concerning their classification and phylogenetic relations...

Solifuges are an enigmatic and poorly studied group of arachnids. Commonly referred to as camel spiders or sun spiders, these animals are voracious predators of small animals and found in arid biomes of the Old World and the Americas. In this paper, we provide a catalogue for the solifuges (Arachnida: Solifugae) that are held at the Center of Natural History in Hamburg. The collections in Hamburg are predominantly historical and were accumulated by Karl Kraepelin between 1889 and 1914 with the help of other famous arachnologists such as Ferdinant Karsch and Eugène Simon...

On October 26, 2015, IARC published a summary of their findings regarding the association of cancer with consumption of red meat or processed meat (IARC 2015a; The Lancet Oncology 2015). The Working Group concluded that there is limited evidence in human beings for carcinogenicity from the consumption of red meat and inadequate evidence in experimental animals for the carcinogenicity of consumption of red meat. Nevertheless, the working group concluded that there is strong mechanistic evidence by which ingestion of red meat can be linked to human colorectal cancer and assigned red meat to Group 2A "probably carcinogenic to humans"...

Contents I. II. III. IV. V. VI. VII. References SUMMARY: Ectomycorrhizal (ECM) associations were historically considered rare or absent from tropical ecosystems. Although most tropical forests are dominated by arbuscular mycorrhizal (AM) trees, ECM associations are widespread and found in all tropical regions. Here, we highlight emerging patterns of ECM biogeography, diversity and ecosystem functions, identify knowledge gaps, and offer direction for future research. At the continental and regional scales, tropical ECM systems are highly diverse and vary widely in ECM plant and fungal abundance, diversity, composition and phylogenetic affinities...

Key breastfeeding outcomes identified by the World Health Organization, the United Nations Children's Fund, the American Academy of Pediatrics, and Healthy People 2020 include early initiation, any such feeding at 6 months of age, and exclusivity. Broader themes in the current literature include infants who ever breastfed and overall duration. Healthcare providers need to know what current practices demonstrate effectiveness. A review of 2 Cochrane articles on which interventions impact these selected outcomes does not reveal any significant implications for clinical practice...
