Abstract
SCOPE A growing body of evidence suggests that the harmful gut microbiota in depression patients can play a role in the progression of depression. There is limited research on troxerutin's impact on the central nervous system (CNS), especially in depression. The study finds that troxerutin effectively alleviates depression and anxiety-like behavior in mice by increasing the abundance of beneficial bacteria like Lactobacillus and Firmicutes while decreasing the abundance of harmful bacteria like Proteobacteria, Bacteroides, and Actinobacteria in the gut. Furthermore, the research reveals that troxerutin regulates various metabolic pathways in mice, including nucleotide metabolism, caffeine metabolism, purine metabolism, arginine biosynthesis, histidine metabolism, 2-oxocarboxylic acid metabolism, biosynthesis of amino acids, glycine, serine and threonine metabolism, and Arginine and proline metabolism. CONCLUSIONS In conclusion, the study provides compelling evidence for the antidepressant efficacy of troxerutin. Through the investigation of the role of intestinal microorganisms and metabolites, the study identifies these factors as key players in troxerutin's ability to prevent depression. Troxerutin achieves its neuroprotective effects and effectively prevents depression and anxiety by modulating the abundance of gut microbiota, including Proteobacteria, Bacteroides, and Actinobacteria, as well as regulating metabolites such as creatine.

Abstract
The aim of the study was to elucidate the therapeutic effects of Atracylodes rhizome polysaccharide on adenine-induced chronic renal failure in rats. Fifty male Sprague Dawley rats were selected and randomly divided in to 5 groups (n=10 rats per group): The normal control group, the chronic renal failure pathological control group, the dexamethasone treatment group and two Atracylodes rhizome polysaccharide treatment groups, treated with two different concentrations of the polysaccharide, the Atracylodes rhizome polysaccharide high group and the Atracylodes rhizome polysaccharide low group. All the rats, except those in the normal control group were fed adenine-enriched diets, containing 10 g adenine per kg food for 3 weeks. After being fed with adenine, the dexamethasone treatment group, Atracylodes rhizome polysaccharide high group and Atracylodes rhizome polysaccharide low group rats were administered the drug orally for 2 weeks. On day 35, the kidney coefficient of the rats and the serum levels of creatinine, blood urea nitrogen, total protein and hemalbumin were determined. Subsequent to experimentation on a model of chronic renal failure in rats, the preparation was proven to be able to reduce serum levels of creatinine, blood urea nitrogen and hemalbumin levels (P<0.05) and improve renal function. Atracylodes rhizome polysaccharide had reversed the majority of the indices of chronic renal failure in rats.

Abstract
Uniformly carbon-covered alumina (CCA) was prepared via the carbonization of sucrose highly dispersed on the alumina surface. The CCA samples were characterized by XRD, XPS, DTA-TG, UV Raman, nitrogen adsorption experiments at 77 K, and rhodamine B (RB) adsorption in aqueous media. UV Raman spectra indicated that the carbon species formed were probably conjugated olefinic or polycyclic aromatic hydrocarbons, which can be considered molecular subunits of a graphitic plane. The N(2) adsorption isotherms, pore size distributions, and XPS results indicated that carbon was uniformly dispersed on the alumina surface in the as-prepared CCA. The carbon coverage and number of carbon layers in CCA could be controlled by the tuning of the sucrose content in the precursor and impregnation times. RB adsorption isotherms suggested that the monolayer adsorption capacity of RB on alumina increased drastically for the sample with uniformly dispersed carbon. The as-prepared CCA possessed the texture of alumina and the surface properties of carbon or both carbon and alumina depending on the carbon coverage.

Abstract
One potential use for prostate-cancer-associated genes discovered through ongoing genetics studies entails the construction of virus- or plasmid-based recombinant vector vaccines encoding these new tumor-associated antigens (TAA) to induce TAA-specific immune responses for the prevention or therapy of prostate cancer. Clinical trials evaluating prototypes of such recombinant vaccines are under way. TAA-encoding recombinant vector vaccines, however, have not previously been evaluated in a prostate-cancer animal model. For assessment of the potential susceptibility of prostate cancer to genetic immunization strategies using TAA-encoding recombinant vectors, the antitumor efficacy of a model recombinant viral vector encoding a TAA was evaluated in rat Dunning prostate cancer. Recombinant vaccinia was chosen as a prototype virus vector encoding a TAA for these studies, and beta-galactosidase was chosen as a model target TAA. Dunning AT-2 cells were transduced with a retroviral vector to express beta-galactosidase, and the susceptibility of tumorigenic AT-2-lacZ cells to immunization with vaccinia-lacZ was measured using protection studies in Copenhagen and nu/nu rats. Stably transduced AT-2-lacZ cells expressing beta-galactosidase as measured by enzymatic substrate-based assays were found to retain their tumorigenicity in vivo despite abundant expression of rat major histocompatibility complex (MHC) class I. Immunization with model TAA-encoding recombinant vaccinia-lacZ conferred significant protection against subsequent growth of AT-2-lacZ cells in vivo (P = 0.01); however, the efficacy of such immunization was markedly dependent on the volume of tumor challenge. The antitumor efficacy of TAA-encoding recombinant vaccinia immunization was abrogated in nu/nu rats, suggesting a T-cell-dependent mechanism of activity. These studies suggest that prostate cancer may be a suitable target for immunization strategies using TAA-encoding recombinant vectors. Such immunization strategies may be more effective in settings of minimal cancer burden.

Abstract
BACKGROUND Evidence that simian virus 40 (SV40) is associated with human mesotheliomas, osteosarcomas, and brain tumors suggests that a recombinant vaccine directed against lethal cancers expressing SV40 T antigen (Tag) could have clinical utility. To address this potential need, we designed a novel vaccinia virus construct that encodes an SV40 Tag in which oncogenic domains were excluded and immunogenic domains were preserved. We named this recombinant construct vaccinia-encoding safety-modified SV40 Tag (vac-mTag). METHODS Purified vac-mTag was characterized by DNA sequencing, reverse transcription-coupled polymerase chain reaction, western blot analysis, and immunocytochemical techniques. Induction of Tag-specific immunity was examined by cytolytic T-cell assays, and the efficacy of vac-mTag in protecting animals against Tag-expressing tumors and in treating pre-established microscopic tumors was evaluated in vac-mTag-immunized BALB/c mice. RESULTS The immune response elicited by vac-mTag in C57BL/6 and BALB/c mice included an SV40 Tag-specific cytolytic T-lymphocyte activity against syngeneic (identical genetic background) SV40 Tag-expressing tumor targets. Immunization of mice with a single dose of vac-mTag resulted in potent protection against subsequent challenge with a lethal mouse cancer expressing SV40 Tag. In addition, single-dose vac-mTag immunization coadministered with interleukin 2 produced a possible therapeutic effect against a preadministered microscopic (but lethal) burden of Tag-expressing tumor cells in vivo. CONCLUSION vac-mTag induces an effective immune response in mice that is specific for a tumor-associated antigen. This response protects against a lethal tumor challenge and results in a possible therapeutic effect against Tag-expressing tumors in vivo. Thus, vac-mTag provides a new avenue for the development of therapies for human cancers thought to be associated with SV40.

Abstract
Intraperitoneal (i.p.) exposure to propanil (3,4-dichloropropionanilide) has previously been shown to affect macrophage cytotoxicity. In this study, we compared the immunotoxic effects of propanil, after different routes of in vivo administration, on cytokine production by thioglycollate-elicited peritoneal macrophages. C57B1/6 mice were treated with either vehicle or 200 mg/kg propanil i.p., or with vehicle, 40, or 400 mg/kg propanil orally. Three or 7 days later, ex vivo production of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) by macrophages after lipopolysaccharide (LPS) stimulation was determined. Both oral and i.p. propanil exposure resulted in up to a 60-70% reduction in IL-6 and TNF-alpha production by the LPS-stimulated macrophages, depending on the route, postexposure time, and dose of propanil administered. Oral exposure to propanil also caused splenomegaly and thymic atrophy in animals in much the same manner as animals exposed via the i.p. route. In vitro exposure to propanil also significantly reduced macrophage cytokine production. Thioglycollate-elicited macrophages from normal mice were cultured in the continuous presence of 0, 10, or 20 microM propanil plus LPS. This exposure caused a significant reduction in IL-6 and TNF protein production by these macrophages in a concentration-dependent manner. Northern blot analysis demonstrated that the message levels of these cytokines were reduced by approximately the same percentage as the protein levels in propanil-treated macrophages, indicating a possible transcriptional or pretranscriptional target(s) for propanil.

Abstract
Our previous studies demonstrated that both in vivo and in vitro 3,4-dichloro-propionanilide (propanil) exposure inhibited interleukin-6 (IL-6) and tumor necrosis factor (TNF) production by adherent thioglycollate-elicited peritoneal cells (macrophages) after lipopolysaccharide (LPS) stimulation. In this study, we report that IL-6 and TNF-alpha message is reduced by propanil in a concentration-dependent pattern, yet the stability of cytokine mRNA is not affected. In addition, exposure of macrophages to propanil after a relatively short period of LPS stimulation significantly reduced the production of IL-6 and TNF. Determination of the intracellular Ca2+ levels demonstrates that LPS-induced Ca2+ release is abrogated in propanil-treated macrophages. However, the binding of LPS to macrophages is not affected. Measurement of inositol 1,4,5-triphosphate (IP3) demonstrates that propanil significantly increases the level and the duration of IP3 in macrophages. These results suggest that the inhibitory effect of propanil on macrophage cytokine production is associated with the early stages of LPS-mediated signal transduction in macrophages.

Abstract
We analyzed the radiological and pathological characteristics of 30 peripheral lung masses 1.5-3 cm in diameter. We describe the vacuole and the nodule sign. Retrospective examination of 100 conventional tomograms of peripheral pulmonary masses and comparison with the histological diagnoses allowed us to determine the usefulness of these two signs in differentiating small peripheral bronchogenic carcinomas from tuberculomas.
