Background: Astronauts will be exposed to both chronic space radiation and acute high doses of energetic radiation of solar particle events in long-term deep space missions. The application of radioprotectors in space missions has basic limitations such as their very short time window as well as their acute toxicity and considerable side effects. The aim of the present study was to investigate ...

A new method of determining the dependence of cell growth on the initial cell volume in the absence of cell division is presented. The assumptions are that volume in a certain period of time is either increasing or decreasing, but not both, and is independent of the history of cells. Applying this method to Gonyaulax polyedra in a 12h light-12h dark cycle, growth in volume between the 3rd and 1...

Fruit spot disease of Phyllanthus emblica L. is one theproblems, which reduce the quality fruits at pre-harvest period. Fungal pathogen was isolated using tissue planting methods during November 2016 to December 2017. The fungus, Thielaviopsis paradoxa identified both morphological and molecular characterization based on internal transcribe spacer (ITS) region ribosomal DNA (rDNA). Mycelial gro...

The evolution of heterocycles from hexaazaanthracene to tetraazapentacenes led to the discovery that syn aza-substituted polyazaacenes possess unusual zwitterionic structures. One of these, 5,7-diphenyl-5H,12H-quinoxalino[2,3-b]phenazine 4, first claimed in 1898 was fully characterized, including an X-ray crystal structure. These heteroacenes have a low calculated singlet-triplet gap and have u...

Abstract Aim Postoperative acute chronic pain following breast surgery is a common complication which needs resolving to allow for improved patient outcomes. Previously thoracic epidurals and paravertebral blocks (PVB) have been the gold standard administered intra-operatively. However, more recently introduction of Pectoral nerve block (PECS PECS-2 blocks) has looked promising control effectiv...

Mycophenolate mofetil (MMF) is a very powerful immunosuppressive drug used in preventing acute rejection in liver transplantation. However, MMF has some serious side effects, including hematologic and gastrointestinal disorders. This study was designed to investigate the relationship between the clinical events and the pharmacokinetics of mycophenolic acid (MPA) in Chinese liver transplant reci...

Anaerobic bioreactors have been developed to remove perchlorate from water, but backwashing and operational interruptions can expose biofilms to oxygen. While it is well known that oxygen is a preferential electron acceptor to perchlorate for perchlorate-respiring bacteria, little is known about the effect of oxygen exposure or redox potentials on perchlorate reduction. Four different dissolved...

Two novel peroxo titanium complexes, Li(2)(NH(4))(4)[Ti(2)(O(2))(2)(cit)(Hcit)](2).5H(2)O and Zn(NH(4))(4)[Ti(4)(O(2))(4)(Hcit)(2)(cit)(2)].12H(2)O (cit = citrate), show encouraging results in the photochemical oxidation of 2-propanol.

The aim of this study was to develop and optimize Trimetazidine dihydrochloride (TM) controlled porosity osmotic pump (CPOP) tablets of directly compressed cores. A 2(3) full factorial design was used to study the influence of three factors namely: PEG400 (10% and 25% based on coating polymer weight), coating level (10% and 20% of tablet core weight) and hole diameter (0 "no hole" and 1 mm). Ot...
