Virginiamycin produced by Streptomyces virginiae as a natural mix of macrocyclic peptidolactones M and S is widely used in the industrial production of ethanol fuel and as an antibiotic feed additive for cattle and poultry. Its main antimicrobial components, M1 and S1 factors, act synergistically if the M1:S1 ratio in the final product is 70-75:25-30. This fact significantly complicates the development of stable high-yield strains suitable for industrial application. In the previous work, authors obtained a mutant S...

Somatic cloning, also known as somatic cell nuclear transfer (SCNT), is a promising technology which has been expected to rapidly extend the population of elaborately selected breeding boars with superior production performance. Chinese Guike No. 1 pig breed is a novel swine specialized strain incorporated with the pedigree background of Duroc and Chinese Luchuan pig breeds, thus inherits an excellent production performance. The present study was conducted to establish somatic cloning procedures of adult breeding boars from the Chinese Guike No...

Bacillus thuringiensis is a bacterium with unusual properties that make it useful for pest control in ecoagriculture. It can form a parasporal crystal containing polypeptides (also called delta-endotoxins). These entomopathogenic toxins are made during the stationary phase of the bacterial growth cycle and were initially characterized as an insect pathogen. Nowadays, the use of saturated two-level designs is very popular. This method is especially used in industrial applications where the cost of experiments is expensive...

Biosurfactants produced by biofilm-forming bacteria have great applications in biotechnology, pharmaceutical, food engineering, bioremediation, and biohydrometallurgy industries. This study aimed to find out the bacteria that produce novel exopolymers (EPSs) which can find potential role in oil biodegradation. A screening procedure was performed to detect EPS-producing bacteria. The EPS producing isolate was identified as Acinetobacter species by 16S rDNA analysis. The polymer produced by the isolate has shown significant emulsification and surfactant activities, and the activities were compared to some of the commercial emulsifiers...

Rho GTPases activating protein 2 (RGA2) is primarily involved in the modulation of numerous morphological events in eukaryotes. It protects plants by triggering the defense system which restricts the pathogen growth. This is the first report on the isolation, purification and characterization of RGA2 from the stems of Tinospora cordifolia, a medicinal plant. The RGA2 was purified using simple two-step process using DEAE-Hi-Trap FF and Superdex 200 chromatography columns, with a high yield. The purity of RGA2 was confirmed by SDS-PAGE and identified by MALDI-TOF/MS...

The present study describes the rapid and efficient indirect lysis method for environmental DNA extraction from athalassohaline soil by newly formulated cell extraction buffer. The available methods are mostly based on direct lysis which leads to DNA shearing and co-extraction of extra cellular DNA that influences the community and functional analysis. Moreover, during extraction of DNA by direct lysis from athalassohaline soil, it was observed that, upon addition of poly ethylene glycol (PEG), isopropanol or absolute ethanol for precipitation of DNA, salt precipitates out and affecting DNA yield significantly...

The present study was conducted to investigate a new pathway for the degradation of nicotinamide adenine dinucleotide (NAD) by Penicillium brevicompactum NRC 829 extracts. Enzymes involved in the hydrolysis of NAD, i.e. alkaline phosphatase, aminohydrolase and glycohydrolase were determined. Alkaline phosphatase was found to catalyse the sequential hydrolysis of two phosphate moieties of NAD molecule to nicotinamide riboside plus adenosine. Adenosine was then deaminated by aminohydrolase to inosine and ammonia...

RATIONALE: Mechanical thrombectomy (MT) with a stent retriever (SR), in association with intravenous (IV) rtPA, is now the standard of care in anterior circulation ischemic stroke caused by large vessel occlusion (LVO). Favorable outcome is strongly associated with the successful reperfusion status. New techniques for MT such as contact aspiration (CA) seem promising to increase reperfusion status and clinical outcome in retrospective studies. We aim at ascertaining whether CA is more efficient than stent retriever as a front-line endovascular procedure...

Actinomycosis is a slowly progressive, chronic infectious disease. It is caused by the genus Actinomyces, which are gram-positive anaerobic bacteria. It presents as a mass-like lesion, composed of bacterial nidus and characteristic granulomatous inflammatory fibrosis. As such, it has frequently been mistaken for a malignancy. Surgical resection is a common procedure in these patients prior to a definite diagnosis. Although actinomycosis can occur in a variety of regions, including oral-cervicofacial, thoracic, and abdominopelvic cavities, the involvement of the pancreas is very rare...

BACKGROUND AND OBJECTIVES: During exposure therapy, patients are encouraged to approach the feared stimulus, so they can experience that this stimulus is not followed by the anticipated aversive outcome. However, patients might treat the absence of the aversive outcome as an 'exception to the rule'. This could hamper the generalization of fear reduction when the patient is confronted with similar stimuli not used in therapy. We examined the effect of providing information about the typicality of the extinction stimulus on the generalization of extinction to a new but similar stimulus...

The skin and the eyes are prone to radiation-induced injury in fluoroscopic procedures. The degree of injury is related to various exposure and patient-related factors. We report a man who presented with an alopecic patch on the left occipital scalp following an extended fluoroscopically-guided endovascular procedure. He subsequently experienced complete hair regrowth, but was later diagnosed with a cataract in his left eye. To our knowledge this is the first report of both anagen effluvium and cataract development in a patient following fluoroscopic radiation exposure...

PURPOSE: Congenitally corrected transposition of the great arteries (CC-TGA) is a complex form of congenital heart defect with numerous anatomic subgroups. The majority of patients with CC-TGA are excellent candidates for a double-switch procedure. However, in the absence of an unrestrictive ventricular septal defect or subpulmonary stenosis, the left ventricle (LV) may undergo involution and require retraining prior to double switch. The purpose of this study was to review our experience with patients having CC-TGA who required LV retraining prior to a double-switch procedure...

BACKGROUND: Adults with congenital heart disease are a growing population. We describe surgical interventions, short- and long-term mortality and morbidity, and risk factors for adverse events in a population-based cohort. METHODS: Patients over or equal to 18 years with congenital heart disease who underwent cardiac surgery at Aarhus University Hospital, Denmark, from 1994 to 2012 were included in the study. Diagnoses, surgical procedures, postoperative complications, and survival were identified in hospital databases, medical records, and the Danish Civil Registration System...
