Functionality of arbuscular mycorrhizal fungi varies across different growth stages of maize under drought conditions.

Physio-biochemical regulations governing crop growth period are pivotal for drought adaptation. Yet, the extent to which functionality of arbuscular mycorrhizal fungi (AM fungi) varies across different stages of maize growth under drought conditions remains uncertain. Therefore, periodic functionality of two different AM fungi i.

Root-to-shoot signaling positively mediates source-sink relation in late growth stages in diploid and tetraploid wheat.

Non-hydraulic root source signaling (nHRS) is a unique positive response to soil drying in the regulation of plant growth and development. However, it is unclear how the nHRS mediates the tradeoff between source and sink at the late growth stages and its adaptive mechanisms in primitive wheat. To address this issue, a root-splitting design was made by inserting solid partition in the middle of the pot culture to induce the occurrence of nHRS using four wheat cultivars (MO1 and MO4, diploid; DM22 and DM31, tetraploid) as materials.

Response of source-sink relationship to progressive water deficit in the domestication of dryland wheat.

It is crucial to clarify the physiological responses of wheat (T. aestivum) plants to source-sink manipulation and assimilation transportation under drought stress during domestication of dryland wheat. In this research, a two-year field experiment was conducted using nine wheat cultivars in a semiarid site of northwest China.

Density- and moisture-dependent effects of arbuscular mycorrhizal fungus on drought acclimation in wheat.

Arbuscular mycorrhizal fungus (AMF) is widely viewed as an ecosystem engineer to help plants adapt to adverse environments. However, a majority of the previous studies regarding AMF's eco-physiological effects are mutually inconsistent. To clarify this fundamental issue, we conducted an experiment focused on wheat (Triticum aestivum L.

Dual plastic film and straw mulching boosts wheat productivity and soil quality under the El Nino in semiarid Kenya.

The extreme climate events such as El Nino seriously threaten crop production and agro-ecological sustainability because of the aggravated environmental stresses worldwide, particularly in sub-Saharan Africa. To address this issue, we investigated the effects of dual plastic film and straw mulching in ridge-furrow (RF) system on wheat productivity, soil carbon and nitrogen stocks in a semiarid area in Kenya from 2015 to 2017. The experimental site represents a typical semiarid continental monsoon climate, and soil type is chromic vertisols.

Association of -174G>C (rs1800795) polymorphism with cervical cancer susceptibility.

Interleukin-6 (IL-6) is a multifunctional cytokine that has been implicated in the etiology of cancer. Several case-control studies have been conducted to assess the association of -174G>C (rs1800795) polymorphism with the risk of cervical cancer, yet with conflicting conclusions. To derive a more precise estimation of the relationship, we performed this meta-analysis updated to June 2018.

XRCC1 polymorphisms and cervical cancer risk: an updated meta-analysis.

X-ray repair cross complementing 1 (XRCC1) plays a key role in DNA repair, genetic instability and tumorigenesis. A series of epidemiological studies have examined associations between XRCC1 polymorphisms and cervical cancer risk, but the findings remain inconclusive. We searched three electronic databases (MEDLINE, EMBASE and CNKI) for studies on the association between XRCC1 polymorphisms and cervical cancer risk published before June 2013.

[Pathological study on effects of preservative-free 1% lidocaine on lens epithelial cells of patients with age-related cataract].

Objective: To assess whether preservative-free 1% lidocaine is capable of destroying the LECs in age-related cataract (ARC) in order to provide scientific basis for pursuing safe and effective drugs to eliminate LECs in cataract surgery.

Methods: Lens anterior capsule (LAC) specimens were collected from 75 patients (82 eyes) with age-related cataract (ARC), including forty males (44 eyes) and thirty-five females (38 eyes). The age range was 41 - 85 years, the mean age was 67.

[Histopathological study of the effect of preservative-free 1% lidocaine on rabbit lens epithelial cells].

Objective: To assess whether preservative-free 1% lidocaine is capable of loosing the junction between the rabbit lens epithelial cells (LECs) and between the cells and capsules and is capable of destroying the LECs, in order to provide scientific basis for pursuing safe and effective drugs to eliminate LECs in cataract surgery and to prevent capsular pacification.

Methods: Lens capsule specimens were collected from 29 rabbits (58 eyes) and divided into 3 groups: balanced salt solution (BSS) group (exposed to BSS for 1 minute), lidocaine group (exposed to preservative-free 1% lidocaine for 1 minute) and the control group. Specimens were stained with trypan blue and alizarin red.
