Effects of volcanic environment on Setaria viridis rhizospheric soil microbial keystone taxa and ecosystem multifunctionality.

Keystone taxa are significant within ecosystem multifunctionality, as certain species fulfil essential functions such as recycling soil nutrients, promoting plant growth, influencing biogeochemical processes, and contributing to human health maintenance. However, there are still gaps regarding the relationship between microbial communities in volcanic rhizospheric soil and ecosystem multifunctionality. As a result, in this research, we employed Illumina MiSeq high-throughput sequencing to analyse the microbial community composition of rhizospheric soil from volcanic S.

Combined Application Effects of Arbuscular Mycorrhizal Fungi and Biochar on the Rhizosphere Fungal Community of L.

Arbuscular mycorrhizal fungi (AMF) are widespread soil endophytic fungi, forming mutualistic relationships with the vast majority of land plants. Biochar (BC) has been reported to improve soil fertility and promote plant growth. However, limited studies are available concerning the combined effects of AMF and BC on soil community structure and plant growth.

A phase II study of preoperative chemotherapy with modified FOLFOX6 followed by surgery and postoperative chemoradiation in patients with localized gastric adenocarcinoma.

The optimal neoadjuvant and adjuvant treatment for gastric cancer remains controversial. We conducted a phase II study using preoperative chemotherapy with modified FOLFOX6 followed by surgical resection and postoperative chemoradiation in patients with gastric carcinoma. Preoperative chemotherapy (two or three cycles) consisted of a 2-h infusion of oxaliplatin (100 mg/m2) and folinic acid (100 mg/m2) followed by a 46-h continuous infusion of 5-fluorouracil (5-FU; 2,400 mg/m2).

1-(Benzyl-ideneamino)pyridinum iodide.

In the title compound, C(12)H(11)N(2) (+)·I(-), the aromatic rings are oriented at a dihedral angle of 73.40 (3)°. In the crystal structure, π-π contacts between the pyridine rings and the benzene and pyridine rings [centroid-centroid distances = 3.

1-(4-Chloro-benzyl-ideneamino)pyridinum iodide.

In the title compound, C(12)H(10)ClN(2) (+)·I(-), the aromatic rings are oriented at a dihedral angle of 54.55 (3)°. In the crystal structure, inter-molecular C-H⋯I and C-H⋯Cl hydrogen bonds link the mol-ecules.

1-(4-Methyl-benzyl-ideneamino)pyridinium iodide.

The title compound, C(13)H(13)N(2) (+)·I(-), is a derivative of 1-amino-pyridinium iodide. The pyridine and benzene rings are oriented at a dihedral angle of 45.78 (3)°.

(2S,3R)-2-[(4-Ethyl-2,3-dioxopiperazin-1-yl)carbonyl-amino]-3-hydroxy-butyric acid monohydrate.

In the title compound, C(11)H(17)N(3)O(6)·H(2)O, an important building block of the medicine cefbuperazone sodium, the piperazine ring adopts a screw-boat conformation. Inter-molecular O-H⋯O and intra-molecular N-H⋯O hydrogen bonds are observed. The water mol-ecule participates as both donor and acceptor in this framework.

Methyl 4-(4-fluoro-phen-yl)-6-isopropyl-2-(methylsulfonyl)pyrimidine-5-carbox-ylate.

The asymmetric unit of the title compound, C(16)H(17)FN(2)O(4)S, contains three independent mol-ecules, in which the pyrimidine and benzene rings are oriented at dihedral angles of 41.72 (3)°, 26.21 (3)° and 36.
