Many computer security problems stem from buggy software. Attackers exploit software bugs to infiltrate systems and install malicious software (malware) such as viruses. Therefore, it is imperative to find bugs before an attacker can exploit them and to detect malware prior to infection. The primary goal of my research is to assure software security. I analyze programs to find bugs and to detec...

Glioblastoma is an aggressive tumor that is associated with distinctive infiltrating microglia/macrophages populations. Previous studies demonstrated that chlorogenic acid (5-caffeoylquinic acid, CHA), a phenolic compound with low molecular weight, has an anti-tumor effect in multiple malignant tumors. In the present study, we focused on the macrophage polarization to investigate the molecular ...

To study how chlorogenic acid affects changes of reactive oxygen species (ROS) and the proteins involved in ROS scavenging of nectarine during storage time, the fruits were treated with chlorogenic acid (CHA) then stored at 25°C for further studies. The CHA-treatment significantly reduced O2-· production rate, H2O2 content, and membrane permeability of nectarine fruit during storage. The key pr...

Aberrant crypt foci (ACF) are putative preneoplastic lesions of colon cancer which are being utilized currently as a biological end point to evaluate the induction and modulation of colon carcinogenesis. In several previous short-term studies, the unexpected reduction of ACF by the reported colonic tumor promoter cholic acid (CHA) emphasized the need for a systematic evaluation of the growth of...

Acrolein (AC) and chloroacetaldehyde (CHA) are metabolites of the non-multidrug resistance cytotoxic drugs cyclophosphamide and ifosfamide. It has previously been reported that both metabolites can induce extensive depletion of glutathione (GSH) in vitro and in vivo and that this depletion occurs at drug concentrations in the micromolar range. A link between the function of the multidrug resist...

Crypt foci with absent or scant mucous production (mucin-depleted foci, MDF) were recently described by our group in the colon of azoxymethane (AOM)-treated rats. Since MDF are dysplastic and easy to quantify, we think that MDF are pre-neoplastic lesions that could be used as biomarkers for carcinogenesis. To test this hypothesis, we studied MDF in azoxymethane (AOM)-initiated rats treated with...

AIMS The CHA(2)DS(2)-VASc score is a modification of the CHADS(2) score that aims to improve stroke risk prediction in patients with atrial fibrillation (AF) by adding three risk factors: age 65-74, female sex, and history of vascular disease. Whereas previous evaluations of the CHA(2)DS(2)-VASc score included all AF patients, the aim of this analysis was to evaluate its discriminative ability ...

Tumour-associated macrophages mainly comprise immunosuppressive M2 phenotypes that promote tumour progression besides anti-tumoural M1 subsets. Selective depletion or reprogramming of M2 may represent an innovative anti-cancer strategy. The actin cytoskeleton is central for cellular homeostasis and is targeted for anti-cancer chemotherapy. Here, we show that targeting G-actin nucleation using c...

To learn how the endogenous polyphenols may play a role in fruit ripening and senescence, apple pulp discs were used as a model to study the influences of chlorogenic acid (CHA, a major polyphenol in apple pulp) on fruit ripening and senescence. Apple ('Golden Delicious') pulp discs prepared from pre-climacteric fruit were treated with 50 mg L(-1) CHA and incubated in flasks with 10 mM MES buff...
