Stemucronatoside K (SMK) and its aglycone stephanthraniline A (STA) are the most representative of a series of novel C21 steriodal compounds that we have previously isolated from Asclepiadaceae plants. The objectives of this study were to investigate the antitumor activity of SMK and STA, and clarify the effect of the sugar chain at the C(3) position. Our results showed that both SMK and STA decreased the growth of HT-29 cells in a dose- and time-dependent manner. Meanwhile, STA showed much stronger inhibitory effect than SMK...

BACKGROUND: The mevalonate pathway synthetizes cholesterol, steroid hormones, and non-steriod isoprenoids necessary for cell survival. 3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) is the rate-limiting enzyme of the mevalonate pathway and the target for statin treatment. HMGCR expression in breast tumors has recently been proposed to hold prognostic and treatment-predictive information. This study aimed to investigate whether HMGCR expression in breast cancer patients was associated with patient and tumor characteristics and disease-free survival (DFS)...

Rheumatoid arthritis (RA) is a chronic systematic autoimmune disease which affects about 1% of the population world wide. This article aimed to identify current therapeutic targets for RA based on data from the literature and drug target related databases. Identified targets were further analysed using a powerful bioinformatics tool, PANTHER (Protein ANalysis THrough Evolutionary Relationships). Additionally, we explored future possible therapeutic targets for RA and discussed the possibility of discovering novel drugs with improved efficacy and reduced toxicity for RA treatment...

Acute disseminated encephalomyelitis (ADEM) develops via an immunological mechanism. We encountered a 10-month-old infant with a rare pathogenesis of cytomegalovirus (CMV)-related ADEM. The patients complaints were; protracted fever; consciousness disorder; and affected cervical stability. Cerebral magnetic resonance imaging (MRI) 9 days after onset, revealed a disseminated lesion, suggesting ADEM. Pulse therapy with methylprednisolone at 30 mg/kg was performed for 3 days. However, its clinical efficacy was not marked...

BACKGROUND: Preterm birth is a major contributor to perinatal mortality and morbidity, affecting around 9% of births in high-income countries and an estimated 13% of births in low- and middle-income countries. Tocolytics are drugs used to suppress uterine contractions for women in preterm labour. The most widely used tocolytic are the betamimetics, however, these are associated with a high frequency of unpleasant and sometimes severe maternal side effects. Calcium channel blockers (CCBs) (such as nifedipine) may have similar tocolytic efficacy with less side effects than betamimetics...

Coho salmon follicles obtained at various times throughout the periovulatory period were incubatedin vitro with graded amounts of partially purified salmon gonadotropin (SG-G100) for 24 h and the amounts of 17β-estradiol, testosterone and 17α20β dihydroxy-4-pregnen-3-one (17α20βP) released into the media determined by radioimmunoassay. By this approach, the pattern of steroid secretion by ovarian follicles was shown to change in relation to the developmental status of the oocyte. Full-grown immature follicles produced large amounts of 17β-estradiol but negligible amounts of testosterone and 17α20βP...

Angiogenesis, the formation of new blood vessels from existing vessels is required for many physiological processes and for growth of solid tumors. Initiated by hypoxia, angiogenesis involves binding of angiogenic factors to endothelial cell (EC) receptors and activation of cellular signaling, differentiation, migration, proliferation, interconnection and canalization of ECs, remodeling of the extracellular matrix and stabilization of newly formed vessels. Experimentally, these processes can be studied by several in vitro and in vivo assays focusing on different steps in the process...

Neutrophilic airway inflammation associated with multiple allergens has been related to steroid-resistant asthma. However, most animal models use only one allergen, which cannot simulate asthma closely as seen in patients. To determine the mechanism of inflammatory process involved in this severe condition, BALB/c mice were repetitively challenged with the pooled extract of dust mite, ragweed, and Aspergillus species (DRA). We found that DRA increased interleukin (IL)-10 and TGF-β levels and neutrophil recruitment in bronchial alveolar lavage fluid...

We reviewed 50 patients admitted to the department of Otorhinolaryngology and Head & Neck Surgery of Govt Medical College Srinagar from September 19% to September 2002 diagnosed with acute epiglottitis. Male were more commonly involved than females in the ratio of 2.8:1 with only 6 cases younger than 10 years of age. The highest incidence was in the month of January (22%). The common symptoms of acute epiglottitis were sorethroat(92%) and odynophagia(88%). Any patient with sudden onset of these symptoms should be suspected of having acute epiglottitis and should have an indirect laryngoscopy...

PURPOSE: We aimed to characterize the association between levels of serum and follicular fluid (FF) adipocytokines, reflected by the leptin to adiponectin ratio (L:A ratio), and oocyte quality and in vitro embryo development in women undergoing assisted reproduction. We also aimed to assess whether follicular hormonal pathways mediate this interaction. METHODS: We prospectively collected FF from up to four individual preovulatory follicles (n = 76) and fasting sera from women (n = 31) without endocrinopathies undergoing in vitro fertilization (IVF) at a university-based center for assisted reproduction...

BACKGROUND: Although smoking has a known association with hot flashes, the factors distinguishing smokers at greatest risk for menopausal symptoms have not been well delineated. Recent evidence supports a relationship between menopausal symptoms and variants in several genes encoding enzymes that metabolize substrates such as sex steriods, xenobiotics, and catechols. It is currently not known whether the impact of smoking on hot flashes is modified by the presence of such variants. OBJECTIVE: The objective of the study was to investigate the relationship between smoking and hot flash occurrence as a function of genetic variation in sex steroid-metabolizing enzymes...
