Development of a novel quantitative function between spectral value and metmyoglobin content in Tan mutton.

This study was aimed to establish a quantitative function between spectral reflectance values and metmyoglobin (MetMb) content in Tan mutton during refrigeration. Near-infrared hyperspectral data combined with generalized two-dimensional correlation spectroscopy (G2D-COS) method to identify characteristic bands and investigate the sequence of chemical waveband changes. Characteristic wavebands identified by G2D-COS analysis had the best performance in predicting the content of MetMb, with a high Rp of 0.

[Value of serum gamma-glutamyl transpeptidase combined with direct bilirubin in the diagnosis of biliary atresia in infants].

Objective: To study the value of serum gamma-glutamyl transpeptidase (GGT) combined with direct bilirubin (DB) in the diagnosis of biliary atresia.

Methods: A total of 667 infants with cholestasis who were hospitalized and treated from July 2010 to December 2018 were enrolled as subjects. According to the results of intraoperative cholangiography and follow-up, they were divided into biliary atresia group with 234 infants and cholestasis group with 433 infants.

Glutamine-fructose-6-phosphate transaminase 2 (GFPT2) promotes the EMT of serous ovarian cancer by activating the hexosamine biosynthetic pathway to increase the nuclear location of β-catenin.

The hexosamine biosynthetic pathway (HBP), a branch of glucose metabolism, provides a substrate for glycosylation modification, which has a wide-ranging effect on cellular functions. Glutamine-fructose-6-phosphate transaminase 2 (GFPT2) has been reported to regulate the HBP as the first and rate-limiting enzyme. Given the inverse association between GFPT2 expression and survival of patients with serous ovarian cancer (SOC) observed in The Cancer Genome Atlas (TCGA) database, we attempted to investigate the role of GFPT2 and its related mechanisms in SOC.

ALPL regulates the aggressive potential of high grade serous ovarian cancer cells via a non-canonical WNT pathway.

The ALPL gene is linked to hypophosphatasia, a rare genetic disease. Owing to the inverse relationships between ALPL expression and both the International Federation of Gynecology and Obstetrics (FIGO) stages and histological grades assigned to patients with serous ovarian cancer (SOC), this study was designed to explore the role and possible mechanisms of ALPL in cell motility of high grade SOC (HGSOC). The effects of ALPL overexpression on migration and invasion were detected in HGSOC cell lines SKOV3 and HEY.

[Phytoremediation of Petroleum Contaminated Soils with Iris pseudacorus L. and the Metabolic Analysis in Roots].

In this study, we performed a greenhouse pot-culture experiment to investigate the potential of a wild ornamental plant Iris pseudacorus L. in remediating petroleum contaminated soils from the Dagang Oilfield in Tianjin, China. The results suggested that Iris pseudacorus L.

[Rhizospheric Mechanisms of Hemerocallis middendorfii Trautv. et Mey. Remediating Petroleum-contaminated Soil and Metabonomic Analyses of the Root Systems].

The effects of a special ornamental plant Hemerocallis middendorfii Trautv. et Mey. on remediating petroleum-contaminated soil from the Dagang Oilfield in Tianjin, China, was studied by a greenhouse pot-culture experiment and the gradients of TPHs were 0, 10,000 and 40,000 mg · kg⁻¹.

Effects of comprehensive intensive therapies on the change of intima-media thickness of carotid arteries in type 2 diabetic patients: A report of 4-year follow-up with a literature review.

Background: The aim was to evaluate the effect of comprehensive intensive therapy on the carotid and femoral arteries of intima-media thickness in patients with type 2 diabetes mellitus after 4-year follow-up.

Methods: In this prospective 4-year study, patients (N = 210) with newly diagnosed type 2 diabetes received either comprehensive intensive therapy (n = 110) or conventional therapy (n = 100). Blood pressure, blood glucose and lipid levels were monitored every 3-6 months, and carotid and femoral arteries of intima-media thickness were monitored with ultrasonography.

An increase in the cerebral infarction area during fatigue is mediated by il-6 through an induction of fibrinogen synthesis.

Objectives: Our study aimed to investigate the impact of fatigue on the severity of stroke and to explore the underlying mechanisms.

Methods: Fatigued male rats underwent middle cerebral artery occlusion and the infarcted brain area was determined. Then, coagulation parameters were assessed in the fatigued group and a control group.

[Analysis of spectral response of vegetation leaf biochemical components].

Based on the leaf spectra data measured with LOPEX'93, the authors analyzed the relationship between leaf spectra and leaf biochemical components including leaf chlorophyll and leaf water content. It was showed that leaf chlorophyll was highly correlated with the second derivation of leaf reflectance at wavelengths 700, 670, 600, 500, 490, 440, and 410 nm; similarly, it was also showed that leaf water content was highly correlated with the continuum removed leaf reflectance at wavelengths 2350, 2180, 2130, 2120, 1870, and 1820 nm, which correspond to the absorption features of water in shortwave infrared bands. In addition, the authors found that ND (Normalized Difference) has a higher response to chlorophyll than other spectral indexes and the correlation coefficient is 0.

[Stable suppression of beta-catenin expression in prostate cancer cell line by retrovirus mediated RNAi].

Objective: To set up a prostate cancer cell line in which beta-catenin expression is stably suppressed and to investigate the role of Wnt/beta-catenin signaling pathway in prostate tumorgenesis.

Methods: We select 3 sites in the complete coden sequence region of beta-catenin gene as the RNAi targets, ligated the annealed double pre-DNA strands into the retroviral vectors pSUPER-retro and transfected them into the packaging cells PA317, and then collected supernatant with retrovirus to infect DU145. After selection by puromycin and culture expansion, the stable cell clones were attained.
