Background: There are currently no studies examining the relationship between systemic inflammatory response and distant metastasis in colorectal cancer patients.

Aims: The aim of this study was to evaluate the association of a systemic inflammatory response on distant metastasis by examining clinicopathological factors in patients with colorectal cancer infiltrating the submucosal layer (T1) or the proper muscular layer (T2).

Methods: Univariate analysis was performed to evaluate the influence of a systemic inflammatory response on distant metastasis in patients with T1 or T2 colorectal cancer using collected clinicopathological data.

We measured the level of heavy metal accumulation in lake sediments, herbivorous (Oreochromis niloticus) and carnivorous (Serranochromis thumbergi) fish, and crayfish (Cherax quadricarinatus) from Lake Itezhi-tezhi (ITT) and Lake Kariba. We used atomic absorption spectrophotometry to quantify the levels of seven heavy metals (Cr, Co, Cu, Zn, Cd, Pb, and Ni). The sediment and the herbivorous fish O.

The objective of this study was to investigate and characterize the metabolic activities of CYP1A in deer, cattle and horses in comparison to those of rats using ethoxyresorufin O-deethylation (EROD) and methoxyresorufin O-demethylation (MROD) assays. We performed an inhibition study for these activities using anti-rat CYP1A1 antibody and identified that these activities were due to the CYP1A subfamily. Interspecies differences in the CYP1A-dependent activities were highly observed in this study.

Introduction: Hypospadias is a common congenital anomaly caused by incomplete fusion of urethral folds. Development of the urethra and external genital system in the male fetus is an androgen-dependent process. In this regard, enzymes 17 β-hydroxysteroid dehydrogenase type 3 (17 β HSD3, encoded by HSD17B3) and steroid 5 α-reductase type 2 (encoded by SRD5A2) play crucial roles.

Helicobacter pylori is a microaerophilic bacterium associated with gastric inflammation and peptic ulcers. Knowledge of how pathogenic organisms produce energy is important from a therapeutic point of view. We found d-amino acid dehydrogenase-mediated electron transport from d-proline or d-alanine to oxygen via the respiratory chain in H.

Background: The Groshong catheter (GC) is considered to have a lower risk of central venous catheter-related bloodstream infection (CVC-RBSI) than conventional catheters because of its valve system (closed-end) for preventing blood reflux. However, few studies have compared the GC with conventional (open-end) catheters in terms of catheter-related complications.

Purpose: To compare the incidence of catheter-related complications including CVC-RBSI between the GC and the Argyle catheter (AC).

A group I intron that can be spliced in vivo and in vitro was identified in the flagellin gene of the thermophilic bacterium Geobacillus stearothermophilus. We also found one or two intervening sequences (IVS) of flagellin genes in five additional bacterial species. Furthermore, we report the presence of these sequences in two sites of a highly conserved region in the flagellin gene.

In this study, we determined a partial sequence of CYP1A1 in the camel and its phylogenetic position. The deduced amino acid sequence of camel CYP1A1 showed the highest identity 94% with those of sheep and cattle CYP1A1. In a phylogenetic analysis, the camel CYP1A1 isoform was located beside sheep and cattle CYP1A1.

Previously, we have reported drastic strain differences of diazepam metabolism in the livers of a variety of rat strain. In this study, to characterize strain and sex differences of diazepam metabolism in the kidney, renal microsomal diazepam metabolic activities were determined in the Dark Agouti (DA), Sprague-Dawley (SD), Brown Norway (BN) and Wistar (WS) strains of rat. We found that the major pathway of diazepam metabolism in the kidney was diazepam N-demethylation, which is different from that in the liver, 3-hydroxylation.

Novel cytochrome P450 1A (CYP1A) cDNA fragments were isolated from the liver of nine Japanese amphibian species using reverse transcription polymerase chain reaction (RT-PCR). Degenerate PCR primers were used to amplify 122-bp fragments of CYP1A cDNAs. Construction of a phylogenetic tree revealed that urodele and anuran amphibians formed two branches.

Pleurotus cornucopiae (PC) mushrooms are found in the field and commonly known in Japan as Tamogidake mushrooms. The present study investigated the protective effects of an aqueous extract of PC on carbon tetrachloride (CCl4)-induced hepatotoxicity and the possible mechanism involved in this protection including cytochrome P450 (CYP) 2E1. Wistar rats were pretreated with aqueous extracts of PC (0, 100, 200, and 400 mg/kg) orally for 8 days prior to the intraperitoneal administration of a single dose of CCl4 (0.

Article Synopsis
  • The study examines the relationship between radiolucency in impacted third molars and acute pericoronitis in patients over 41 years old.
  • While the overall frequency of inflammation was similar regardless of radiolucency, older age groups, particularly women over 61, showed significantly higher odds of developing acute inflammation.
  • The findings suggest that elderly patients are at an increased risk for severe acute pericoronitis associated with pericoronal radiolucency, highlighting the need for careful monitoring in this demographic.

Rats are an important tool in pharmacology and toxicology. The authors focus on rat P450s in relation to diazepam metabolism. In particular, considerable attention is devoted to the CYP2D subfamily, which is a group of highly polymorphic enzymes.

Background: The Centers for Disease Control and Prevention guideline recommended the use of 2% chlorhexidine as a percutaneous disinfectant for central venous catheter (CVC) insertion. However, in Japan, 0.05% chlorhexidine is commonly used as well as 10% povidone-iodine, instead of 2% chlorhexidine.

Background: Recent studies have revealed that the modified Glasgow Prognostic Score (mGPS), an inflammation-based prognostic score that includes only C-reactive protein (CRP) and albumin, is a useful tool for predicting postoperative outcome in cancer patients. However, few studies have investigated the mGPS in patients undergoing chemotherapy for far-advanced or recurrent unresectable colorectal cancer (AR-UCRC).

Objective: To demonstrate the influence of the mGPS for prognostication of patients undergoing chemotherapy for AR-UCRC.

Flagellin glycosylation was identified in Bacillus sp. PS3 and Geobacillus stearothermophilus. In vivo complementation showed that these flagellin genes did not restore the motility of a Bacillus subtilis flagellin mutant, whereas the genes encoding non-glycosylated flagellin from Geobacillus kaustophilus and Bacillus sp.

Cytochrome P450 (P450) 2D2 (CYP2D2) enzyme is known to metabolize the majority of typical substrates of the human CYP2D6 enzyme, which is the most extensively characterized polymorphic drug-metabolizing enzyme. Despite its impact on drug metabolism in rats, the transcriptional regulation of CYP2D2 remains to be elucidated. We clarified the molecular mechanism of CYP2D2 gene expression.

An ethogram is a catalogue of discrete behaviors typically employed by a species. Traditionally animal behavior has been recorded by observing study individuals directly. However, this approach is difficult, often impossible, in the case of behaviors which occur in remote areas and/or at great depth or altitude.

Background: Few studies have investigated the Glasgow Prognostic Score (GPS) in patients with liver metastases from colorectal cancer (LM-CRC).

Methods: The GPS was calculated as follows: patients with both an elevated level of CRP (>10 mg/L) and hypoalbuminemia (Alb <35 g/L) were allocated a score of 2, and patients showing one or neither of these blood chemistry abnormalities were allocated a score of 1 or 0, respectively.

Results: Ninety-three patients were evaluated retrospectively.

We investigated the blood status of 9 Weddell seal mothers and 9 pups during the breeding season in a field study conducted from November to December 2004 at a breeding colony in Antarctica. The blood glucose and total cholesterol concentrations were higher in the pups than in the mothers. On the other hand, the blood urea nitrogen concentration was lower in the pups than in the mothers.

Prolonged abnormal vomiting causes metabolic alkalosis. Many seabirds are known to feed their chicks by regurgitation. We hypothesized that metabolic alkalosis occurs in seabirds even under natural conditions during the breeding season.
