The causal relationship between gut microbiota and preterm birth: a two-sample Mendelian randomization study.

Background: Preterm birth, a significant global health concern, has been associated with alterations in the gut microbiota. However, the causal nature of this relationship remains uncertain due to the limitations inherent in observational studies.

Purpose: To investigate the potential causal relationship between gut microbiota imbalances and preterm birth.

Proteomic profiling of the endogenous peptides of MRSA and MSSA.

is a Gram-positive bacterium that can cause diverse skin and soft tissue infections. Methicillin-resistant (MRSA) can cause more severe infections than methicillin-susceptible (MSSA). Nevertheless, the physiological and metabolic regulation of MSSA and MRSA has not been well studied.

Lentinan ameliorates burn sepsis by attenuating CD4 CD25 Tregs.

Aim: The aim of our study was to investigate the effect of lentinan on regulatory T cells (Tregs) in sepsis, especially on the generation of interleukin (IL)-10 via regulation of Erk-FoxO1 signaling.

Methods: BalB/c mice were randomized into five groups: sham group, the group with burns plus Pseudomonas aeruginosa infection, and the groups with burns plus P. aeruginosa infection administered 40, 100, and 250mg/kg of lentinan.

[N'-(3-Eth-oxy-2-oxidobenzyl-idene)-4-hy-droxy-3-meth-oxy-benzohydrazidato](methanol)dioxidomolybdenum(VI).

In the title dioxidomolybdenum(VI) complex, [Mo(C(17)H(16)N(2)O(5))O(2)(CH(3)OH)], the Mo(VI) atom is coordinated by the phenolate O, imine N and enolic O atoms of the tridentate hydrazone ligand, one methanol O atom, and two oxide O atoms, forming a distorted octa-hedral coordination geometry. The oxide O atoms adopt a cis conformation: one is trans to the methanol O atom and the other is trans to the ligand N atom. The dihedral angle between the two benzene rings in the hydrazone ligand is 4.

cis-Bis[2-(cyclo-propyl-imino-meth-yl)-6-methoxy-phenolato]bis-(thio-cyanato)cobalt(II).

In the title compound, [Co(NCS)(2)(C(11)H(13)NO(2))(2)], a mononuclear Schiff base cobalt(II) complex, the Co atom is six-coordinated by four O atoms from two Schiff base ligands, and by two N atoms from two thio-cyanate ligands, forming a distorted octa-hedral geometry. The central Co atom lies on a twofold rotation axis. An intramolecular N-H⋯O hydrogen bond is present.

Spectroscopic and theoretical studies on nickel(II) complex of maleonitriledithiolate and 2,2'-bipyridine.

The complete IR spectra of the title complex Ni(mnt)(bpy) (mnt=maleonitriledithiolate, bpy=2,2'-bipyridine) and a new method to analyze vibrational spectra for such a complicated metal complex are reported in this paper. The molecular geometry, binding, electronic structure and spectroscopic property of it have been studied in detail by theoretical calculations. The geometry optimization from PM3 calculations give that this molecule is of a planar structure with the symmetry point group C(2v) and its ground state is the spin triplet state.
