Optimization of preparation conditions and performance of a new degradable soil water retaining agent.

Using polyaspartic acid (PAsp) and bentonite (BT) as the main raw materials, a new type of degradable soil water retaining agent (PAsp-AA/BT) was synthesized by microwave radiation. The optimum synthesis conditions and comprehensive properties of PAsp-AA/BT were discussed and the structure and surface characteristics of PAspsp-AA/BT were characterized by FTIR, SEM, XRD and TGA in the paper. The results showed that the optimum synthesis conditions of PAsp-AA/BT were as follows: the dosages of polyaspartic acid (PAsp), bentonite (BT), initiator potassium persulfate, crosslinking agent N,N'-methylene bisacrylamide was 5, 3, 0.

Phytohormones-mediated strategies for mitigation of heavy metals toxicity in plants focused on sustainable production.

In this manuscript, authors reviewed and explore the information on beneficial role of phytohormones to mitigate adverse effects of heavy metals toxicity in plants. Global farming systems are seriously threatened by heavy metals (HMs) toxicity, which can result in decreased crop yields, impaired food safety, and negative environmental effects. A rise in curiosity has been shown recently in creating sustainable methods to reduce HMs toxicity in plants and improve agricultural productivity.

Metagenomics reveals the effect of long-term fertilization on carbon cycle in the maize rhizosphere.

Long-term fertilization can result in the changes in carbon (C) cycle in the maize rhizosphere soil. However, there have been few reports on the impacts of microbial regulatory mechanisms on the C cycle in soil. In the study, we analyzed the response of functional genes that regulate the C fixation, decomposition and methane (CH) metabolism in maize rhizosphere soil to different fertilization treatments using metagenomics analysis.

A novel fully human anti-CD47 antibody as a potential therapy for human neoplasms with good safety.

Strategies for targeting CD47 are becoming a hot spot of cancer immunotherapy. However the ubiquitous expression of CD47, especially on the RBC, makes the targeted therapy facing safety risk issues. So, how to balance the safety and efficacy during CD47 inhibition is currently a major question.

Air-Stable Black Phosphorus Devices for Ion Sensing.

Black phosphorus (BP) is one of the most attractive graphene analogues, and its properties make it a promising nanomaterial for chemical sensing. However, mono- and few-layer BP flakes are reported to chemically degrade rapidly upon exposure to ambient conditions. Therefore, little is known about the performance and sensing mechanism of intrinsic BP, and chemical sensing of intrinsic BP with acceptable air stability remains only theoretically explored.

Increasing stability of antibody via antibody engineering: stability engineering on an anti-hVEGF.

Antibody stability is very important for expression, activity, specificity, and storage. This knowledge of antibody structure has made it possible for a computer-aided molecule design to be used to optimize and increase antibody stability. Many computational methods have been built based on knowledge or structure, however, a good integrated engineering system has yet to be developed that combines these methods.
