Altered RBC deformability in diabetes: clinical characteristics and RBC pathophysiology.

Background: Reduced red blood cell deformability (RBCD) is associated with diabetic vascular complications, but early pathophysiological RBC changes and predictive demographic and clinical factors in populations with diabetes are unclear. An understanding of early diabetes-specific RBC changes associated with impaired RBCD is essential in investigating mechanisms that predispose to diabetic vascular complications.

Methods: We conducted an outpatient cross-sectional study of participants in a well-controlled diabetes cohort (N81) and nondiabetic controls (N78) at the National Institutes of Health.

The inhibition of hypoxia-induced angiogenesis and metastasis by cinnamaldehyde is mediated by decreasing HIF-1α protein synthesis via PI3K/Akt pathway.

Tumor hypoxia is positively correlated with tumor aggressiveness and hence is a negative prognostic factor in cancer. As normal cells usually do not experience such low oxygen levels, hypoxic cell signaling has attracted significant attention for the development of tumor-selective treatment strategies. In response to hypoxia, the master transcriptional regulator, HIF-1α plays central role in cellular adaptation by transactivating several crucial downstream target genes, which are involved in angiogenesis, metastasis, and EMT.

Nrf-2 transcriptionally activates P21 and promotes A549 cell survival against oxidative stress induced by HO.

Cancer cells possess elevated ROS coupled with increased levels of antioxidant enzymes which render them resistant against cytotoxic chemotherapies. Therefore, an understanding of the interaction between key molecules involved in stress adaptive mechanisms is important to innovate strategies against cancer cell chemoresistance. Here, the lung adenocarcinoma cell line A549 with constitutively expressed Nrf2 was found to be more tolerant to HO (0.

Tailoring the Efficacy of Multifunctional Biopolymeric Graphene Oxide Quantum Dot-Based Nanomaterial as Nanocargo in Cancer Therapeutic Application.

Nanotechnology has acquired an immense recognition in cancer theranostics. Considerable progress has been made in the development of targeted drug delivery system for potent delivery of anticancer drugs to tumor-specific sites. Recently, multifunctional nanomaterials have been explored and used as nanovehicles to carry drug molecules with enhanced therapeutic efficacy.

LINCRNA00273 promotes cancer metastasis and its G-Quadruplex promoter can serve as a novel target to inhibit cancer invasiveness.

Discovery of anti-metastatic drugs is of immense clinical significance as metastasis is responsible for 90% of all cancer deaths. Here we report the inhibitory effect of a bis schiff base (M2) on cancer cell migration and invasion and . M2 has shown good solubility and permeability across the intestinal cell wall and hence can be classified as BCS (Biopharmaceutical classification system) class I.

Evaluation of the Antioxidant Activity of Extracts and Active Principles of Commonly Consumed Indian Spices.

Accumulating evidence suggests that free radical reactions play a key part in the development of degenerative diseases and that an antioxidant-rich diet is a major defense against these free radical reactions. In this study, we explore comparative antioxidant capacities of extracts of some commonly used in Indian spices (anise, cardamom, Ceylon cinnamon, and clove) along with their purified components (anethole, eucalyptol, cinnamaldehyde, and eugenol, respectively). Eugenol shows the highest 1,1-diphenyl-2-picrylhydrazyl, hydroxyl, and superoxide scavenging and reducing power activity in terms of weight; however, this was not found when compared in terms of equivalence.

Exposure to environmentally relevant concentrations of malathion induces significant cellular, biochemical and histological alterations in Labeo rohita.

The extensive use of malathion, an organophosphate pesticide, raises the possibility of its undesirable toxicity to non-target organisms. Agricultural run-off and vector control sprays are the major sources of exposure to this pesticide for aquatic organisms. Some earlier studies have reported the presence of malathion at concentrations ranging from 18.

Antitumorigenic potential of linalool is accompanied by modulation of oxidative stress: an in vivo study in sarcoma-180 solid tumor model.

Coriander, used as a common food seasoning, contains linalool as the main constituent of its essential oil. In this study, we tested the effect of linalool vis-à-vis that of a conventional chemotherapeutic drug, cyclophosphamide, against solid S-180 tumor-bearing Swiss albino mice. Tumor volume, cell count, cell cycle phase distribution, apoptosis, and proliferation markers indicate that linalool has potent antitumor activity.

Amelioration of cyclophosphamide induced myelosuppression and oxidative stress by cinnamic acid.

Cinnamic acid (C9H8O2), is a major constituent of the oriental Ayurvedic plant Cinnamomum cassia (Family: Lauraceae). This phenolic acid has been reported to possess various pharmacological properties of which its antioxidant activity is a prime one. Therefore it is rational to hypothesize that it may ameliorate myelosuppression and oxidative stress induced by cyclophosphamide, a widely used chemotherapeutic agent.
