| • | Novel Technique For Fluorescence Tomography Of Tumors In Living Animals | ||
| Fluorescent molecules -- i.e. substances which can be stimulated to emit light -- are extremely valuable tools in biological research and medical diagnosis. Fluorescence can be used for instance to analyze the regulation and expression of genes, to locate proteins in cells and tissues, to follow metabolic pathways and to study the location and migration of cells. Of particular importance is the combination of fluorescence imaging with novel techniques that allow tomographic three-dimensional visualization of objects in living organisms. | |||

| • | In vitro testing of rationally designed spermicides for selectively targeting human sperm in vagina to ensure safe contraception | ||
|
Rational synthesis of novel structures resulted in two unique molecules (DSE-36 and DSE-37, disulphide esters of carbothioic acid) that killed sperm 25 times more strongly and with a precisely targeted action than nonoxynol-9 (N-9). We examine the effects of DSE-36 and DSE-37 on human spermatozoa versus HeLa cells to establish specificity and safety compared with N-9. At spermicidal EC100 (20 µg/ml) DSE-36 and DSE-37 killed 100% sperm in <30 s (Sander–Cramer assay) and at EC50 induced apoptosis in sperm (Annexin-V-fluorescein isothiocyanate and JC-1 labelling and Flow Cytometry) in 3 h. However, at EC100 these molecules had no effect on HeLa cells by 24 h or on cell viability [3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay], surface ultrastructure (scanning electron microscopy), Annexin-V and JC-1 labelling pattern and reactive oxygen species (ROS) generation. N-9, with a spermicidal EC100 of 500 µg/ml, decreased HeLa cell viability at 20 µg/ml in 24 h (P < 0.001), accompanied by acute damage to cell surface ultrastructural topography, induction of apoptosis and ROS generation. Unlike DSE-36 and DSE-37, N-9 also significantly induced mRNA levels (RT–PCR) of pro-inflammatory biomarkers (interleukin (IL)-1, IL-6, IL-8, RANTES) in HeLa cells and increased IL-6 and IL-8 secretion (P < 0.001, enzyme-linked immunosorbent assay). Furthermore, DSE-36 and DSE-37 did not inhibit Lactobacillus growth at EC100 and exhibited mild microbicidal activity against Trichomonas vaginalis, while N-9 inhibited Lactobacillus and Trichomonas growth but had a lower prophylactic index. The ability of these novel spermicides to kill sperm almost instantaneously at innocuously low concentration indicates their worth as improved active ingredients for vaginal contraceptive preparations compared with N-9. |

| • | Naked Scientists 08.06.15 - Fire and Mud | ||
| Get Red Hot and Dirty with the Naked Scientists as we explore the science of volcanoes. We discover how the heat from hot rocks can be used to work out what gases are emerging, how likely a volcano is to erupt and whether it will go with a bang or a whimper. We also hear how hot runny rock can shatter under pressure to trigger an earthquake, and dip into the cooler, dirtier world of mud Volcanoes, like Lusi, which is currently pouring millions of gallons of mud onto the island of Java. Plus, we find out how a small date plant made history by being the oldest seed ever to germinate, why the paper of the future could be as tough as iron, and, in Kitchen Science, Ben and Dave provoke an eruption of their own! | |||

| • | Antiinflammatory and antinociceptive activities of gossypin and procumbentin - cyclooxygenase-2 (cox-2) inhibition studies | ||
| In the present study the antiinflammatory and antinociceptive activities of a few selected flavonoids were investigated. Procumbentin, gossypin, chrysin and methylhespiridin were studied for antiinflammatory and antinociceptive activities using in vitro enzymatic assays and in animal models utilizing acetic acid-induced writhing in mice and hind paw edema in rats. In vitro studies were performed using TMPD (NNN[prime]N[prime]-tetramethyl-p-phenylene diamine) and oxygraphic methods for COX-1 (cyclooxygenase-1), COX-2, 5-LOX (5-lipoxygenase) and 15-LOX. Gossypin and procumbentin showed COX-2 inhibitory activity and exhibited IC50 (COX-2/COX-1) ratios of 0.14 and 0.11, respectively. None of the flavonoids tested in this study showed LOX inhibitory activity. Four groups were studied for each t... | |||
