Candida albicans, along with some other non-albicans Candida species, is a group of yeast, which causes serious infections in humans that can be both systemic and superficial. Despite the fact that extensive efforts have been put into the discovery of novel antifungal agents, the frequency of these fungal infections has increased drastically worldwide. In our quest for the discovery of novel an...

Reversion of L forms to the normal bacterial state has been described in general terms in a variety of bacterial cell-L-form systems (Dienes and Weinberger, 1951). The relatively large 3B type L colony formed on penicillin-containing medium is composed entirely of spherical bodies of varying sizes (2 to 10 ,u in diameter) that appear to propagate by a budding process. In contrast, 3A type L for...

Two bichromophoric systems are presented that contain an N-alkylnaphthalimide electron acceptor and a 4-methoxyaniline (3a) or an aniline (3b) electron donor, respectively. Upon photoexcitation of 3a in cyclohexane electron transfer occurs in the singlet manifold to afford the short-lived (τf ) 0.75 ns) 1(D+-A-) state in ca. 70% yield. An important decay pathway of this D+-Astate consists of in...

BACKGROUNDS Predicting the development of acute kidney injury (AKI) in the critical care setting is challenging. Although several biomarkers showed somewhat satisfactory performance for detecting established AKI even in a heterogeneous disease-oriented population, identification of new biomarkers that predict the development of AKI accurately is urgently required. METHODS A single-center pros...

Contrast-induced acute kidney injury (CI-AKI) is a serious complication of diagnostic coronary angiograph and percutaneous coronary intervention (PCI). However, the exact pathophysiological mechanisms underlying CI-AKI development are largely unknown. The present study examined whether urinary semaphorin 3A levels predict the development of CI-AKI in patients undergoing PCI. This study enrolled...

Reaction of 4-hydroxy-7-methoxy-2(lH)-quinolone (1) with iodosobenzenes, prepared in situ from the dichloroiodo compounds 2a,b, afforded the iodoniumylides 3a,b in good yields. Their thermal rearrangement produced the 3-iodo-4-aryloxy-quinolones 4a,b. Reductive -deiodinatton of 4a,b gave the corresponding arylethers 5a,b. By photocyclization 4a as well as 5a yielded the benzofuro-quinolone 6a (...

A series of curcumin pyrazole derivatives (3a-3e) were investigated for in-vitro hypolipidemic activity. The compounds were screened for the inhibition studies of the enzymes such as pancreatic lipase, glucose 6 phosphate dehydrogenase and malate dehydrogenase which are actively involved in lipid metabolism. Curcumin and all the other compounds in the series showed differential enzyme inhibitor...

Attempts were made to elucidate the acetyl transformation of novel trichothecene mycotoxins, 3a,7a,15-trihydroxy-12,13-epoxytrichothec-9-en-8-one (deoxynivalenol) and its derivatives, by trichothecene-producing strains of Fusarium nivale, F. roseum, and F. solani. In the peptone-supplemented Czapek-Dox medium, F. roseum converted 3a-acetoxy-7a,15-dihydroxy-12,13-epoxytrichothec-9-en-8-one (3-ac...

GADD45α is a stress-induced gene activated by a variety of stress stimuli, including ultraviolet and ionizing radiation, and involved in cell cycle regulation, apoptosis, maintenance, genomic stability, DNA repair and immune response. However, the effects and regulatory mechanism of GADD45α on proliferation, apoptosis and DNA damage repair of hepatocytes in liver regeneration remains unclear. I...

Scar tissue at sites of traumatic injury in the adult central nervous system presents a combined physical and molecular impediment to axon regeneration. Of multiple known central nervous system scar associated axon growth inhibitors, semaphorin 3A has been shown to be strongly expressed by invading leptomeningeal fibroblasts. We have previously demonstrated that infusion of the small leucine-ri...
