Multidrug resistance (MDR) caused by overexpression of p-glycoprotein is a major obstacle in chemotherapy of malignant cancer, which usually is characterized by constitutive activation of signal transducer and activator of transcription 3 (STAT3), but their relation between MDR and STAT3 remains unclear. Here, we showed that STAT3 was overexpressed and highly activated in adriamycin-resistant K...

Medical or health care waste (HCW) refers to all waste generated by health care facilities, research facilities, and laboratories. Health care waste management (HCWM) is a major health and environmental concern. Hazardous waste, including sharps and other infectious waste, pose a serious risk to human health and the general environment. In many developing countries, disposing of this waste is c...

BACKGROUND Monogenic obesity is a rare type of obesity caused by a mutation in a single gene. Patients with monogenic obesity may develop early onset of obesity and severe metabolic abnormalities. CASE PRESENTATION A two-and-half-year-old girl was presented to our clinic because of excessive weight gain and hyperphagia. She was born at full term, by normal vaginal delivery with birth weight o...

Mast cells (MCs) are tissue resident cells, rich in inflammatory mediators, involved in allergic reactions, and with an increasingly recognized role in immunomodulation. Dendritic cells (DCs), on the other hand, are central to the determination of immune response patterns, being highly efficient antigen-presenting cells that respond promptly to changes in their microenvironment. Here, we show t...

The contraction phase of antigen-specific immune responses involves the apoptotic loss of numerous activated lymphocytes. While apoptotic cells are known to induce immune suppression, the mechanisms involved therein are still ambiguous. Some reports have speculated that macrophages can induce regulatory T cells (Tregs) after engulfing apoptotic cells. In this study, we showed that dendritic cel...

Col.:•r Anal>Jsi s 2 This study• used a pre/post test design to investigate the effects of a color analysis by Suzanne Cagyill on the self-concept of women. The individual's value system was examined for its effect on integration of the color process. Personality correlations of participants using Suzanne's Season typology were also investigated. Ninety-eight subjects, 94 women and 4 men, compl...

Previous studies have documented that leptin is involved in the pathogenesis of many human cancer types by regulation of numerous signal transduction pathways. The aim of this study was to investigate the biological roles of leptin and the mechanisms attributed to its action in non-small cell lung cancer (NSCLC) cell lines. The expression of leptin was measured by quantitative real-time PCR and...

The inventory of proteins used in different kingdoms appears surprisingly similar in all sequenced eukaryotic genome. Protein domains represent the basic evolutionary units that form proteins. Domain duplication and shuffling by recombination are probably the most important forces driving protein evolution and hence the complexity of the proteome. While the duplication of whole genes as well as...
