Cystathionine--synthase expression correlates with tumour progression and adverse prognosis in patients with colon cancer.

Objective: To investigate the levels of cystathionine-β-synthase (CBS) in colon cancer tissues compared with adjacent control tissues; and to examine the relationship between CBS level and clinical characteristics and prognosis.

Methods: This retrospective study enrolled patients with primary colon cancer. Paraffin-embedded specimens were used to create pathological tissue microarrays.

The promotion of liver regeneration in mice after a partial hepatectomy as a result of the modulation of macrophage activation by dexmedetomidine.

Background: This study investigates the effect of dexmedetomidine (DEX), a highly selective agonist of alpha 2-adrenergic receptors (α2-ARs), on the regulation of hepatic macrophage activation in liver regeneration.

Methods: A two-thirds partial hepatectomy (PHx) mouse model was performed. DEX (25 μg/kg) or a vehicle control (saline) was injected i.

Distribution of bacteria infected by metagenomic sequencing technology in maxillofacial space.

Objectives: This study aimed to compare and analyze the consistency and difference between metageno-mic next-generation sequencing (mNGS) and conventional bacterial culture in the detection of pathogenic microorganisms in maxillofacial space infection, as well as to provide a new detection method for the early clinical identification of pathogenic bacteria in maxillofacial space infection.

Methods: The clinical data of 16 patients with oral and maxillofacial space infections in the First Affiliated Hospital of Zhengzhou University from March 2020 to June 2020 were collected. mNGS and conventional bacterial culture methods were used to detect pus.

Clinical significance of LMO1 in gastric cancer tissue and its association with apoptosis of cancer cells.

It has been reported that LMO1 gene was associated with progression, metastasis and apoptosis of leukemia, colorectal cancer and lung cancer. However, the association of LMO1 and gastric cancer remains unclear. The aim of this study is to analyze the relation between LMO1 expression and apoptosis of gastric cancer cells and explore the clinical implications of LMO1 in gastric cancer tissues.

Effects of Granulocyte Colony-Stimulating Factor on Opsonin Receptor Expression and Neutrophil Antibacterial Activity in a Mouse Model of Severe Acute Pancreatitis.

The antimicrobial function of neutrophils, which is dependent on opsonin receptors, deteriorates in severe acute pancreatitis (SAP). Granulocyte colony-stimulating factor (G-CSF) putatively enhanced levels of the opsonin receptors CD11b and CD32/16 in healthy human subjects, and provided protection against infection in animal models of SAP. A statistically convincing study of the effect of G-CSF on CD32/16 expression in an SAP model is lacking.

Naringenin inhibits proliferation, migration, and invasion as well as induces apoptosis of gastric cancer SGC7901 cell line by downregulation of AKT pathway.

The preliminary anti-cancer activity of Naringenin (Nar) has been proven in several cancers. However, the therapeutic activity of Nar on gastric cancer SGC-7901 cell line is not yet well understood. The aim of the present study was to investigate the effect and mechanisms of Nar on proliferation, apoptosis, migration, and invasion of SGC-7901 cells.

[Effects of diallyl disulfide on apoptosis of human leukemia K562 cells and expression of Fas, FasL and caspase-8].

Objective: To study the effects of diallyl disulfide (DADS) on apoptosis of human leukemia K562 cells and possible mechanisms.

Methods: The morphologic changes of leukemia K562 cells after DADS treatment were observed by Hoechst 33258 staining. Cell apoptosis rates after different concentrations and different durations of DADS treatment were determined by flow cytometry.

Transport functions and expression analysis of vacuolar membrane aquaporins in response to various stresses in rice.

The vacuole, a multifunctional organelle of most plant cells, has very important roles in space filling, osmotic adjustment, storage and digestion. Previous researches suggested that aquaporins in the tonoplast were involved in vacuolar functions. The rice genome contains 33 aquaporin genes, 10 of which encode tonoplast intrinsic proteins (TIPs).

Alkali grass resists salt stress through high [K+] and an endodermis barrier to Na+.

In order to understand the salt-tolerance mechanism of alkali grass (Puccinellia tenuiflora) compared with wheat (Triticum aestivum L.), [K(+)] and [Na(+)] in roots and shoots in response to salt treatments were examined with ion element analysis and X-ray microanalysis. Both the rapid K(+) and Na(+) influx in response to different NaCl and KCl treatments, and the accumulation of K(+) and Na(+) as the plants acclimated to long-term stress were studied in culture- solution experiments.
