No complications occurred. After a mean follow-up of 14±6 months, no recurrent VT was documented in 2/2 pts with baseline VT and a mean 84% reduction in PVC burden (31±13% vs 4±5% PVC/d; p=0,0027) was documented in others. CONCLUSION In pts with LVS-VAs arising from the inaccessible region and refractory to conventional RFA, an anatomical approach utilizing Bi-RFA from the LPC and opposite LVOT is an effective alternative approach. ETHNOPHARMACOLOGICAL RELEVANCE Medicinal Earths (MEs), natural aluminosilicate-based substances (largely kaolinite and montmorillonite), have been part of the European pharmacopoeia for well over two millennia; they were used generically as 'antidotes to poison'. AIM OF THE STUDY To test the antibacterial activity of three Lemnian and three Silesian Earths, medicinal earths in the collection of the Pharmacy Museum of the University of Basel, dating to 16th-18th century and following a prescribed methodology (see graphical abstract). To assess and prioritize the parameters which drive their antibacterial activity, if present. MATERIALS AND METHODS The medicinal earths are characterised chemically (ICP-MS), mineralogically (both bulk (XRD) and at the nano-sized level (TEM-EDAX)); their organic load (bacterial and fungal) is DNA-sequenced; their bioactivity (MIC60) is tested against Gram-positive, S. aureus and Gram-negative, P. aeruginosa. The bioactivities (MIC60) of natural clays from Lemnos, N Aegean, and Melos, SW Aegean, spiked with Al, Fe, Ti, and B are also tested against the same pathogens for purposes of comparison. RESULTS Not all MEs are antibacterial. Of the three Lemnian Earths, only two are antibacterial against both pathogens; of the Silesian Earths only one is mildly antibacterial and against Gram-negative pathogen, only. The bioactivity of the two Lemnian Earths is driven by a fungal component, Talaromyces spp, a fungus of the family of Trichocomaceae (order Eurotiales), historically associated with Penicillium. This fungus was not found in the natural Lemnos clays examined here. Comparable bioactivity with that of the two Lemnian Earths can be obtained from kaolinitic/smectitic clays spiked with B or Al. CONCLUSIONS It is not known whether archaeological medicinal earths were used as antibacterials, over and above as absorbants of toxins. Nevertheless, some display antibacterial properties which appear to have their origins in an organic (fungal) load. V.ETHNOPHARMACOLOGICAL RELEVANCE Dipsacus asper Wall. ex C.B. Clarke, a traditional Chinese herbal medicine, has long been used in China for the therapy of bone diseases (e.g. find protocol bone fracture, osteoporosis, rheumatic arthritis), traumatic hematoma, uterine bleeding and those caused by the deficiency of liver and kidney. AIM OF THE STUDY This work aims to evaluate current research progress on chemical constituents, pharmacological activities, quality control, and pharmacokinetic of Dipsacus asper Wall. ex C.B. Clarke, pinpoint the shortcomings of existing studies, and provide meaningful guidelines for our future investigations. METHODS Extensive database retrieval, such as PubMed, SciFinder and CNKI, was carried out by using keywords such as "Dipsacus asper", "Radix Dipsaci", and "Xuduan". Furthermore, relevant textbooks, patents, reviews, and digital documents were consulted to collate all available scientific literature and to provide a complete science-based survey of the topic. RESULTS More than 100 compounds ioactivities, such as anti-inflammatory and free radical scavenging, which are shared in many other plant species. Pharmacological effects of individual component of DA is not equivalent to its traditional usage. Attention should be paid to the traditional effect of extract of DA. The oxygen-limiting condition promotes the accumulation of ployhydroxybutyrate (PHB) in C. necator H16, while the growth of which is restricted. Under autotrophic culture using carbon dioxide, hydrogen, and oxygen as substrates, the oxygen concentration below 6.9% (v/v) in the mixture is considered as a safe condition. It also expected to achieve cell rapid growth and large accumulation of PHB simultaneously under the oxygen-limiting condition in C. necator H16. In this study, a metabolically engineered strain capable of both rapid growth and large accumulation of PHB under oxygen-limiting conditions was constructed based on the transcriptomic analysis. In the comparative transcriptomic analysis, the genes related to energy-generating of C. necator H16 at autotrophic culture were downregulated under oxygen-limiting conditions (3%, v/v). Besides, the genes related to the key intermediates (pyruvate and acetyl-CoA) metabolism in PHB biosynthetic pathway were analyzed. Most of which were downregulated, except thtion of Reh01 (p2M-pj-v) increased by 31.0%, 30.9%, and 71.5%, respectively. From the perspectives of transcriptome and metabolic engineering, the work provides new ideas to achieve rapid cell growth and large PHB accumulation in C. necator under oxygen-limiting and autotrophic conditions. Tetrahydrobiopterin (BH4) is an endogenous cofactor for various enzymatic conversions of essential biomolecules including nitric oxide, tyrosine, dopamine, serotonin and phenylalanine. Depending on the physiological functions of these molecules, BH4 plays multiple roles in the cardiovascular, immune, nervous and endocrine systems. A deficiency of BH4 or an imbalance of the redox state of biopterin has been implicated in various cardiovascular and metabolic diseases. Therefore, supplementation with BH4 is considered as a therapeutic option for these diseases. In addition to the classical nitric oxide synthase (NOS)-dependent role of BH4, recent studies proposed novel NOS-independent roles of BH4 in health and disease conditions. This article reviews the updated role of BH4 in mitochondrial regulation, energy metabolism and cardiovascular and metabolic diseases. Cryptosporidiosis is an obligate intracellular pathogen causing diarrhea. Merozoite egress is essential for infection to spread between host cells. However, the mechanisms of egress have yet to be defined. We hypothesized that Cyclic GMP-Dependent Protein Kinase G (PKG) may be involved in Cryptosporidium egress. In this study, Cryptosporidium parvum PKG was silenced by using antisense RNA sequences. PKG-silencing significantly inhibited egress of merozoites from infected HCT-8 cells into the supernatant and led to retention of intracellular forms within the host cells. This data identifies PKG as a key mediator of merozoite egress, a key step in the parasite lifecycle.
