Interleukin-8 and clinical symptoms can be prognostic indicators for advanced cancer patients with cachexia.

Objectives: Prognostic prediction is a significant tool for selecting appropriate treatment in advanced cancer patients with cachexia, at a time when it is important to offer high-quality palliative care and improve quality of life until death. In this retrospective study, we investigated the prognostic potential of serum cytokine level and various clinical symptoms by analyzing the pathological conditions and metabolic dynamics of cachexia in advanced cancer patients.

Methods: One hundred and fifty-three advanced cancer patients who underwent palliative care and died at the Department of Surgery and Palliative Medicine, Fujita Health University Nanakuri Memorial Hospital between 1 January 2004 and 30 June 2007 were eligible for the study.

Effects of exercise and bryostatin-1 on serotonin dynamics after cerebral infarction.

Although it has been suggested that the combination of exercise and bryostatin-1 administration may induce greater functional recovery than exercise alone, the detailed molecular mechanisms are not well known. Here, we examined the relationship between this combination treatment and monoamine dynamics in the cerebral cortex peri-infarction area to promote our understanding of these molecular mechanisms. Experimental cerebral cortex infarctions were produced by photothrombosis in rats.

Effects of occlusal disharmony on the hippocampal dentate gyrus in aged senescence-accelerated mouse prone 8 (SAMP8).

Background And Objective: Malocclusion induced by raising the bite causes chronic stress. Chronic stress leads to increased plasma corticosterone levels and impaired hippocampal function due to impaired neurogenesis or increased apoptosis in the hippocampus. The present study aimed to clarify the mechanisms underlying the impaired hippocampal function induced by the bite-raised condition in aged senescence-accelerated mouse prone 8 (SAMP8).

Hippocampus-dependent spatial memory impairment due to molar tooth loss is ameliorated by an enriched environment.

Background And Objective: Teeth are crucial, not only for mastication, but for overall nutrition and general health, including cognitive function. Aged mice with chronic stress due to tooth loss exhibit impaired hippocampus-dependent learning and memory. Exposure to an enriched environment restores the reduced hippocampal function.

Effects of Aloe-emodin and Emodin on Proliferation of the MKN45 Human Gastric Cancer Cell Line.

Aloe-emodin (1, 8-dihydroxy-3-hydroxyl-methylanthraquinone; AE) and emodin (1,3,8-trihydroxy-6- methylanthraquinone; EM) are anthraquinone derivatives that have been detected in some medical plants and share similar anthraquinone structures. AE and EM have been shown to exhibit anticancer activities in various cancer cell lines; however, the inhibitory effects of these derivatives on the growth of cancer cells were previously reported to be different. Gastric cancer is the second most common cause of cancer cell death worldwide.

Protein kinase C activator, bryostatin-1, promotes exercise-dependent functional recovery in rats with cerebral infarction.

Recently, it has become widely known that neuronal reorganization in the perilesional cortex contributes to some improvement of hemiparesis after stroke. Here, the authors examined in vivo the effects of administration of bryostatin-1, an activator of protein kinase C, combined with voluntary exercise on functional recovery and on cortical phosphorylation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor subunit GluR1 after infarction.In behavioral evaluation, the mean latency until falling from a rotating rod in the group with exercise and administered agent at 8 days after infarction was significantly longer than that in the other groups.

Inhibitory effects of low-dose aloe-emodin on the development of colorectal tumors in min mice.

Aloe-emodin (AE), a natural anthraquinone compound, has been reported to exhibit anticancer activity in various cancer cell lines and anti-inflammatory effects in murine macrophages. In the present study, we investigated the cancer chemopreventive effects of AE in an Apc-deficient Min mouse model. In the first experiment, male Min mice were fed a basal diet or diets containing 5 ppm AE and 10 ppm AE for 12 weeks.

Reduction of intestinal polyp formation in min mice fed a high-fat diet with aloe vera gel extract.

Aloe vera gel supercritical CO2 extract (AVGE) has been shown to contain five phytosterols, reduce visceral fat accumulation, and influence the metabolism of glucose and lipids in animal model experiments. Recent epidemiologic studies have shown that obesity is an established risk factor for several cancers including colorectal cancer. Therefore, we examined the effects of AVGE on intestinal polyp formation in Apc-deficient Min mice fed a high-fat diet.

Experimental Research on Stimulation of Wound Healing by n-3 Fatty Acids.

Unlabelled: Objexctive. The objective of this study was to investigate the wound healing effects of n-3 fatty acids and to identify factors that stimulate wound healing.

Materials And Methods: Four-week-old male Wistar rats were subjected to full-thickness skin wounds and assigned to 3 experimental diet groups (an n-3 fatty acid-fortified diet, a diet with a 1:3 ratio of n-3 to n-6 fatty acids, and an n-6 fatty acid-fortified diet).

Functional recovery and alterations in the expression and localization of protein kinase C following voluntary exercise in rat with cerebral infarction.

Recently, it has become widely known that rehabilitative training after stroke brings about some improvement of paralysis and disability; however, not much is known about the relationship between paralysis recovery and the participation of plasticity-related molecules. Hence, the localization and level of expression of several proteins in the cerebral cortex of rat groups with/without voluntary exercise using a running wheel after photo thrombotic infarction were examined in this study. In behavioral evaluation, the mean latency until falling from a rotating rod in the group with voluntary exercise at 6 days after infarction was significantly longer than that in the group without exercise.

Inhibition of ENNG-induced pyloric stomach and small intestinal carcinogenesis in mice by high temperature- and pressure-treated garlic.

High temperature- and pressure-treated garlic (HTPG) has been shown to have enhanced antioxidative activity and polyphenol contents. Previously, we reported that HTPG inhibited 1,2-dimethylhydrazine-induced mucin depleted foci (premalignant lesions) and O6-methylguanine DNA adduct formation in the rat colorectum. In the present study, we investigated the modifying effects of HTPG on N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG)- induced pyloric stomach and small intestinal carcinogenesis in mice.

Effects of exercise after focal cerebral cortex infarction on basal ganglion.

Identification of functional molecules in the brain related to improvement of motor dysfunction after stroke will contribute to establish a new treatment strategy for stroke rehabilitation. Hence, monoamine changes in basal ganglion related to motor control were examined in groups with/without voluntary exercise after cerebral infarction. Cerebral infarction was produced by photothrombosis in rats.

Alteration of protein expression profile following voluntary exercise in the perilesional cortex of rats with focal cerebral infarction.

Identification of functional molecules in the brain related to improvement of the degree of paralysis or increase of activities will contribute to establishing a new treatment strategy for stroke rehabilitation. Hence, protein expression changes in the cerebral cortex of rat groups with/without voluntary exercise using a running wheel after cerebral infarction were examined in this study. Motor performance measured by the accelerated rotarod test and alteration of protein expression using antibody microarray analysis comprised 725 different antibodies in the cerebral cortex adjacent to infarction area were examined.

Inhibition of 1, 2-dimethylhydrazine-induced mucin-depleted foci and O⁶-methylguanine DNA adducts in the rat colorectum by boiled garlic powder.

The scavenging capacity of reactive oxygen species, such as hydroxyl radicals, is reported not to decrease in boiled garlic (an odorless garlic preparation). We therefore examined the modifying effect of boiled garlic powder (BGP) on 1,2-dimethylhydrazine-induced mucin-depleted foci (MDF) and aberrant crypt foci (ACF), preneoplastic lesions, in the rat colorectum. Male F344 rats (5 weeks old) were fed a basal diet, or experimental diets containing 5% or 1% BGP for 5 weeks.

Metformin suppresses azoxymethane-induced colorectal aberrant crypt foci by activating AMP-activated protein kinase.

Metformin is widely used for the treatment of diabetes mellitus. Adenosine monophosphate-activated protein kinase (AMPK) is known to be activated by metformin and to inhibit the mammalian target of rapamycin (mTOR) pathway. The mTOR pathway plays an important role in the protein translational machinery and cell proliferation.
