BTS 67582 (1,1-dimethyl-2-(2-morpholinophenyl) guanidine fumarate) is an insulin-releasing agent currently in phase II clinical trials. Its effect on advanced glycation end product (AGE) formation was measured in the BSA/D-glucose and L-lysine/glucose-6-phosphate assay systems and Amadori product formation was measured in the BSA/D-glucose assay system, following a 3 week incubation period. In the BSA/D-glucose assay system, 200 mM BTS 67582 caused an approximate 70% inhibition in AGE formation (pBTS 67582 and 200 mM aminoguanidine-HCl retarded Amadori product formation by 88% (pBTS 67582 at 20 mM and 2 mM was shown to inhibit Amadori product formation by 67% and 57%, respectively, (pBTS 67582 and 200 mM aminoguanidine-HCl were shown to inhibit AGE formation by about 70% and 96% (p<0.001), respectively. Tolbutamide (200 microM) and glibenclamide (100 microM) had no significant effect on AGE formation.

This Office of Space Flight (OSF)-funded project sought to demonstrate the application of a Bi-metallic Treatment System (BTS) to remove and degrade PCBs found on NASA facilities. The project initiated with the collection of PCB-containing materials from various MSFC and KSC structures, followed by laboratory evaluation of the BTS' PCB-removal efficiency, and concluded with a field demonstration at MSFC. The project evaluated the optimum formulation required to remove PCBs from aged and weathered paint with the goal of achieving final PCB concentrations less than 50 mg/Kg or 50 percent reduction where PCB starting levels were already below the 50 mg/Kg levels. Using lessons learned from this study, it was anticipated that the research team would be better able to make further recommendation on application strategies for future use of BTS for the treatment of PCB laden coatings on structures.

1. BTS 67582 (1,1-dimethyl-2-(2-morpholinophenyl)guanidine fumarate) is a novel antidiabetic agent with a short-acting insulin-releasing effect. This study examined its mode of action in the clonal B-cell line BRIN-BD11. 2. BTS 67582 increased insulin release from BRIN-BD11 cells in a concentration-dependent manner (10[-8] to 10[-4] M) at both non-stimulating (1.1 mM) and stimulating (16.7 mM) concentrations of glucose. 3. BTS 67582 (10[-4] M) potentiated the insulin-releasing effect of a depolarizing concentration of K+ (30 mM), whereas the K+ channel openers pinacidil (400 microM) and diazoxide (300 microM) inhibited BTS 67582-induced release. 4. Suppression of Ca+ channel activity with verapamil (20 microM) reduced the insulin-releasing effect of BTS 67582 (10[-4] M). 5. BTS 67582 (10[-4] M) potentiated insulin release induced by amino acids (10 mM), and enhanced the combined stimulant effects of glucose plus either the fatty acid palmitate (10 mM), or agents which raise intracellular cyclic AMP concentrations (25 microM forskolin and 1 mM isobutylmethylxanthine), or the cholinoceptor agonist carbachol (100 microM). 6. Inhibition of glucose-stimulated insulin release by adrenaline or noradrenaline (10 microM) was partially reversed by BTS 67582 (10[-4] M). 7. These data suggest that the insulin-releasing effect of BTS 67582 involves regulation of ATP-sensitive K+ channel activity and Ca2+ influx, and that the drug augments the stimulant effects of nutrient insulin secretagogues and agents which enhance adenylate cyclase and phospholipase C. BTS 67582 may also exert insulin-releasing effects independently of ATP-sensitive K+ channel activity.

Biphasic insulin-releasing effect of BTS 67 582 in rats.

Storey, D A; Bailey, C J

1998-12-01

BTS 67 582 (1,1-dimethyl-2(2-morpholinophenyl)guanidine fumarate) is being developed as a short-acting anti-diabetic insulin secretagogue. The effect of BTS 67 582 on the phasic pattern of insulin release was assessed in anaesthetized normal rats by measuring arterial plasma insulin concentrations while arterial glucose concentrations were fixed at 6, 8.5 and 12.5 mM. Intravenous BTS 67 582 (10 mg kg(-1)) induced an immediate but transient increase in insulin concentrations which declined by 10 min (first phase). This was followed by a smaller but sustained increase in insulin concentrations (second phase). The increment from basal to peak insulin release (0-2 min) was independent of glucose, but the first phase was maintained for longer and the second phase was greater at the highest concentration of glucose (12.5 mM). BTS 67 582 also extended the first-phase insulin response to a standard intravenous glucose challenge and enhanced the rate of glucose disappearance by approximately 12%. Thus BTS 67 582 causes biphasic stimulation of insulin release and augments the insulin-releasing effect of glucose.

Lymphocyte proliferation is regulated by signals through antigen receptors, co-stimulatory receptors, and other positive and negative modulators. Several membrane tetraspanning molecules are also involved in the regulation of lymphocyte growth and death. We cloned a new B cell-specific tetraspanning (BTS) membrane molecule, which is similar to CD20 in terms of expression, structure and function. BTS is specifically expressed in the B cell line and its expression is increased after the pre-B cell stage. BTS is expressed in intracellular granules and on the cell surface. Overexpression of BTS in immature B cell lines induces growth retardation through inhibition of cell cycle progression and cell size increase without inducing apoptosis. This inhibitory function is mediated predominantly by the N terminus of BTS. The development of mature B cells is inhibited in transgenic mice expressing BTS, suggesting that BTS is involved in the in vivo regulation of B cells. These results indicate that BTS plays a role in the regulation of cell division and B cell growth.

Private communications inside large vehicles such as ships may be effectively provided using standard cellular systems. In this paper we propose a new solution based on software-defined radio with electromagnetic sensing support. Software-defined radio allows low-cost developments and, potentially, added-value services not available in commercial cellular networks. The platform of reference, OpenBTS, only supports single-channel cells. Our proposal, however, has the ability of changing BTS channel frequency without disrupting ongoing communications. This ability should be mandatory in vehicular environments, where neighbouring cell configurations may change rapidly, so a moving cell must be reconfigured in real-time to avoid interferences. Full details about frequency occupancy sensing and the channel reselection procedure are provided in this paper. Moreover, a procedure for fast terminal detection is proposed. This may be decisive in emergency situations, e.g., if someone falls overboard. Different tests confirm the feasibility of our proposal and its compatibility with commercial GSM terminals.

While 18 h BTS 67 582 culture did not affect the insulin-releasing actions (PBTS 67 582 shares a common signalling pathway to sulphonylurea but not imidazoline drugs. Desensitization of drug action may provide an important approach to dissect sites of action of novel and established insulinotropic antidiabetic agents.

BTS 72664-- a novel CNS drug with potential anticonvulsant, neuroprotective, and antimigraine properties.

2001-01-01

BTS 72664, (R)-7-[1-(4-chlorophenoxy)]ethyl]-1,2,4-triazolo(1,5-alpha)pyrimidine, was identified as a drug development candidate from a research program designed to discover novel, broad-spectrum, non-sedative anticonvulsant drugs. BTS 72664 antagonized bicuculline (BIC)- and maximal electroshock (MES)-induced convulsions with ED(50) values of 1.9 and 47.5 mg/kg p.o., respectively. In rodents, it has a wide spectrum of activity preventing seizures induced by picrotoxin, pentylenetetrazol, i.c.v. 4-aminopyridine or NMDA, and audiogenic seizures in DBA-2 mice and GEPR-9 rats. BTS 72664 was also effective in preventing convulsions in amygdala-kindled rats The lack of sedative potential was predicted on the basis of wide separation between ED(50) in anticonvulsant models and TD(50) for motor impairment in mice in rotating rod and inverted horizontal grid tests. BTS 72664 is likely to produce its anticonvulsant effect by enhancing chloride currents through picrotoxin-sensitive chloride channels, and by weak inhibition of Na(+) and NMDA channels. It does not act, however, at the benzodiazepine binding site. In addition to its potential use in the treatment of epilepsy BTS 72664 may be useful in the treatment of stroke. At 50 mg/kg p.o. x 4, given to rats at 12 hourly intervals, starting at 15 min after permanent occlusion of middle cerebral artery (MCA), it reduced cerebral infarct size by 31% (measured at 2 days after insult) and accelerated recovery in a functional behavioral model. BTS 72664 prevented increases in extraneuronal concentrations of glutamate, glycine and serine brain levels induced by a cortical insult to rats (cf. cortical spreading depression). It may, therefore, have also antimigraine activity.

Management of spontaneous pneumothorax compared to British Thoracic Society (BTS) 2003 guidelines: a district general hospital audit.

Science.gov (United States)

Medford, Andrew Rl; Pepperell, Justin Ct

2007-10-01

In 1993, the British Thoracic Society (BTS) issued guidelines for the management of spontaneous pneumothorax (SP). These were refined in 2003. To determine adherence to the 2003 BTS SP guidelines in a district general hospital. An initial retrospective audit of 52 episodes of acute SP was performed. Subsequent intervention involved a junior doctor educational update on both the 2003 BTS guidelines and the initial audit results, and the setting up of an online guideline hyperlink. After the educational intervention a further prospective re-audit of 28 SP episodes was performed. Management of SP deviated considerably from the 2003 BTS guidelines in the initial audit - deviation rate 26.9%. After the intervention, a number of clinical management deviations persisted (32.1% deviation rate); these included failure to insert a chest drain despite unsuccessful aspiration, and attempting aspiration of symptomatic secondary SPs. Specific tools to improve standards might include a pneumothorax proforma to improve record keeping and a pneumothorax care pathway to reduce management deviations compared to BTS guidelines. Successful change also requires identification of the total target audience for any educational intervention.

Disagreement exists between different COPD guidelines considering classification of severity of the disease. The aim of our study was to determine whether there is any correlation between severity scales of various COPD guidelines (ATS, BTS, ERS and GOLD) and the frequency of hospitalisations for COPD exacerbation. A cohort of 67 COPD patients (65 male 2 female, 45 ex-smokers, 22 current smokers, aged (69.4 +/- 1.1)) was recruited from those admitted in the pulmonary clinic of the University Hospital of Heraklion, Crete for an acute exacerbation. Lung function tests and arterial blood gases analyses were performed during stable conditions at a scheduled visit 2 months after discharge. The patients were stratified using the FEV1 percent-predicted measurement of this visit into mild, moderate and severe in accordance to the ATS, BTS, ERS and GOLD scales of severity. The number of hospitalisations for acute exacerbation was recorded for the following 18 months. A total of 165 exacerbations were recorded. The correlation between the severity of COPD and the number of hospitalisations per year was statistically significant using the GOLD classification system of severity (P = 0.02 and r = 0.294). A weak correlation was also found between the number of hospitalisations and the ERS classification system (P = 0.05 and r = 0.24). No statistically significant correlation was found between the number of hospitalisations and the ATS or BTS severity scales. In conclusion the GOLD and ERS classification systems of severity of COPD correlated to exacerbations causing hospitalisation. The same was not true for the ATS and BTS severity scales. Better correlation was achieved with the GOLD scale.

Fertility results of artificial inseminations performed with liquid boar semen stored in X-cell vs BTS extender.

The objective of the present field study was to compare the fertility results for boar semen diluted in X-cell stored up to 4-5 days before artificial insemination (AI) with semen diluted in Beltsville thawing solution (BTS) used for AI following 2-3 days of storage (where the first day being the collection day). A total number of 2601 double inseminations in Norwegian herds were included in this two-trial study. All the boars used in the study were mature cross-bred Norwegian Landrace x Duroc (LD), which were routinely used for AI in Norway. The inseminated gilts and sows were Norwegian Landrace x Yorkshire (LY). The AI doses contained 2.5 billion spermatozoa, and consisted of a mixture of semen from three, occasionally four, boars (i.e. heterospermic semen). Fertility was measured in terms of the likelihood of farrowing and subsequent litter size. The fertility of the semen in both of the extenders was satisfactory and no significant differences were found either in semen stored 4-5 days in X-cell compared with 2-3 days in BTS or in semen stored 2-3 days in X-cell compared with 2-3 days in BTS. The storage capability findings for the long-term extender X-cell could significantly simplify the practical issues of semen production and the distribution of AI doses containing 2.5 billion spermatozoa. However, in pig production systems where all semen is used within 2-3 days, the short-term extender BTS is as good as the more expensive extender X-cell.

Metabolomics for functional genomics, systems biology, and biotechnology.

2010-01-01

Metabolomics now plays a significant role in fundamental plant biology and applied biotechnology. Plants collectively produce a huge array of chemicals, far more than are produced by most other organisms; hence, metabolomics is of great importance in plant biology. Although substantial improvements have been made in the field of metabolomics, the uniform annotation of metabolite signals in databases and informatics through international standardization efforts remains a challenge, as does the development of new fields such as fluxome analysis and single cell analysis. The principle of transcript and metabolite cooccurrence, particularly transcriptome coexpression network analysis, is a powerful tool for decoding the function of genes in Arabidopsis thaliana. This strategy can now be used for the identification of genes involved in specific pathways in crops and medicinal plants. Metabolomics has gained importance in biotechnology applications, as exemplified by quantitative loci analysis, prediction of food quality, and evaluation of genetically modified crops. Systems biology driven by metabolome data will aid in deciphering the secrets of plant cell systems and their application to biotechnology.

Cross-bridge blocker BTS permits direct measurement of SR Ca2+ pump ATP utilization in toadfish swimbladder muscle fibers.

Science.gov (United States)

Young, Iain S; Harwood, Claire L; Rome, Lawrence C

2003-10-01

Because the major processes involved in muscle contraction require rapid utilization of ATP, measurement of ATP utilization can provide important insights into the mechanisms of contraction. It is necessary, however, to differentiate between the contribution made by cross-bridges and that of the sarcoplasmic reticulum (SR) Ca2+ pumps. Specific and potent SR Ca2+ pump blockers have been used in skinned fibers to permit direct measurement of cross-bridge ATP utilization. Up to now, there was no analogous cross-bridge blocker. Recently, N-benzyl-p-toluene sulfonamide (BTS) was found to suppress force generation at micromolar concentrations. We tested whether BTS could be used to block cross-bridge ATP utilization, thereby permitting direct measurement of SR Ca2+ pump ATP utilization in saponin-skinned fibers. At 25 microM, BTS virtually eliminates force and cross-bridge ATP utilization (both BTS. At 25 microM, BTS had no effect on SR pump ATP utilization. Hence, we used BTS to make some of the first direct measurements of ATP utilization of intact SR over a physiological range of [Ca2+]at 15 degrees C. Curve fits to SR Ca2+ pump ATP utilization vs. pCa indicate that they have much lower Hill coefficients (1.49) than that describing cross-bridge force generation vs. pCa (approximately 5). Furthermore, we found that BTS also effectively eliminates force generation in bundles of intact swimbladder muscle, suggesting that it will be an important tool for studying integrated SR function during normal motor behavior.

Effects of a myosin-II inhibitor (N-benzyl-p-toluene sulphonamide, BTS) on contractile characteristics of intact fast-twitch mammalian muscle fibres.

Science.gov (United States)

Pinniger, G J; Bruton, J D; Westerblad, H; Ranatunga, K W

2005-01-01

We have examined the effects of N-benzyl-p-toluene sulphonamide (BTS), a potent and specific inhibitor of fast muscle myosin-II, using small bundles of intact fibres or single fibres from rat foot muscle. BTS decreased tetanic tension reversibly in a concentration-dependent manner with half-maximal inhibition at approximately approximately 2 microM at 20 degrees C. The inhibition of tension with 10 microM BTS was marked at the three temperatures examined (10, 20 and 30 degrees C), but greatest at 10 degrees C. BTS decreased active muscle stiffness to a lesser extent than tetanic tension indicating that not all of the tension inhibition was due to a reduced number of attached cross-bridges. BTS-induced inhibition of active tension was not accompanied by any change in the free myoplasmic Ca2+ transients. The potency and specificity of BTS make it a very suitable myosin inhibitor for intact mammalian fast muscle and should be a useful tool for the examination of outstanding questions in muscle contraction.

Lane, E L; Cheetham, S C; Jenner, P

2005-01-01

BTS 74 398 (1-[1-(3,4-dichlorophenyl)cyclobutyl]-2-(3-diaminethylaminopropylthio)ethanone monocitrate) is a monoamine reuptake inhibitor that reverses motor deficits in MPTP-treated (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) common marmosets without provoking established dyskinesia. However, it is not known whether BTS 74 398 primes the basal ganglia for dyskinesia induction. In this study, the ability of BTS 74 398 to sensitize 6-hydroxydopamine (6-OHDA)-lesioned rats for the production of abnormal motor behaviours and the induction of striatal DeltaFosB were determined in comparison with l-3,4-dihydroxyphenylalanine methyl ester (L-dopa). Acute administration of BTS 74 398 induced a dose-dependent ipsilateral circling response in unilaterally 6-OHDA-lesioned rats whereas L-dopa produced dose-dependent contraversive rotation. The ipsilateral circling response to BTS 74 398 did not alter during 21 days of administration. In contrast, L-dopa treatment for 21 days caused a marked increase in rotational response. Repeated administration of both L-dopa and BTS 74 398 increased general motor activity and stereotypic behaviour. In L-dopa-treated rats, orolingual, locomotive, forelimb and axial abnormal movements developed whereas BTS 74 398 produced only locomotion with a side bias but no other abnormal movements. Sensitization of circling responses and the development of abnormal movements in 6-OHDA-lesioned rats have been associated with the potential of dopaminergic drugs to induce dyskinesia. Furthermore, striatal DeltaFosB immunoreactivity, shown to correlate with dyskinesia induction, was increased by L-dopa but was unaffected by repeated BTS 74 398 administration. The lack of such changes following repeated BTS 74 398 treatment suggests that it may be an effective antiparkinsonian therapy that is unlikely to produce involuntary movements.

Colonic stent insertion is widely used as a bridge to surgery(BTS)for obstructive colorectal cancer. Stenting can shorten hospitalization and decrease complication and colostomy rates in comparison with emergency surgery. We investigated patients who underwent colonic stent insertion for BTS in our hospital. Sixteen patients(8 men, 8 women) with a colorectal obstruction score of 0 or 1 who underwent colonic stent insertion as a BTS between April 2015 and April 2017 period were investigated. Mean patient age was 68.2(45-94)years. Technical success was obtained in all patients, and clinical success in 14(87%). Total colonoscopy was possible via stent in 10 patients. Nine patients were temporarily discharged from the hospital, and median time to operation was 18(2-43)days. Laparoscopic resection was performed in 14 patients, and anastomotic leakage was a postoperative complication in 1 patient. Colostomy was performed in only 1 patient with anastomotic leakage. Good results were obtained with careful patient selection and safe colonic stent insertion.

Androhep Plus, a long-term extender (up to 7 days) and Beltsville Thawing Solution (BTS), a short-term extender (up to 3 days), are commonly used for liquid storage of porcine semen. To test the hypothesis that modifications in sperm viability, motility, chlortetracycline (CTC) fluorescence patterns, and protein tyrosine phosphorylation occur during semen storage in extenders, we compared these end points at different periods of storage in either Androhep Plus or BTS. Sperm from five boars were assessed daily over 12 days of storage (n = 5 ejaculates from different boars). Viability was not different (P extenders, except on Day 2, when Androhep Plus maintained better viability. Differences in the percentage of motile (total) sperm due to extender were evident on Days 2, 4, 5, and 6, when Androhep Plus was superior to BTS (P extender as early as Day 2; storage in Androhep Plus induced higher levels of pattern B sperm (P extenders; these may affect the fertilizing capacity of the semen.

Alienation from the Objectives of the Patent System: How to Remedy the Situation of Biotechnology Patent.

Science.gov (United States)

Jiang, Li

2018-03-12

Some fundamental biotechnologies hold unprecedented potential to eradicate many incurable diseases. However, in absence of regulations, the power of patent makes the future use of some important biotechnology in few institution's hands. The excessive patents restrict researcher access to the fundamental technologies. It generates concerns and complaints of deteriorating the public health and social welfare. Furthermore, intellectual curiosities, funding, respect among colleagues etc., rather than patents, are the real motivations driving a major ground-breaking discoveries in biotechnology. These phenomena reveal that some biotechnology patents are alienated from the purpose of patent system. Therefore, it is necessary to take some approaches to stop over-patenting these fundamental biotechnology inventions. This article proposes a model regulatory framework for controlling biotechnology patent alienating from the purpose of patent system.

Abstract Background: Aim of the present study was to evaluate whether the presence of body shadows during virtual reality (VR) training with BTS NIRVANA (BTs-N) may lead to a better functional recovery. Methods: We enrolled 20 poststroke rehabilitation inpatients, who underwent a neurocognitive-rehabilitative training consisting of 24 sessions (3 times a week for 8 weeks) of BTs-N. All the patients were randomized into 2 groups: semi-immersive virtual training with (S-IVTS group) or without (S-IVT group) body shadows. Each participant was evaluated before (T0) and immediately (T1) after the end of the training (Trial Registration Number: NCT03095560). Results: The S-IVTS group showed a greater improvement in visuo-constructive skills and sustained attention, as compared with the S-IVT group. The other measures showed nonsignificant within-group and between-group differences. Conclusion: Our results showed that body shadow may represent a high-priority class of stimuli that act by “pushing” attention toward the body itself. Further studies are needed to clarify the role of body shadow in promoting the internal representation construction and thus self-recognition. PMID:28930852

This paper tries to yield an economic valuation of biotechnological activities in terms of aggregated production and employment. This valuation goes beyond direct estimation and includes the indirect effects derived from sectorial linkages between biotechnological activities and the rest of economic system. To deal with the proposed target several sources of data have been used, including official data from National Statistical Office (INE) such us national accounts, input-output tables, and innovation surveys, as well as, firms' level balance sheets and income statements and also specific information about research projects compiled by Genoma Spain Foundation. Methodological approach is based on the estimation of a new input-output table which includes the biotechnological activities as a specific branch. This table offers both the direct impact of these activities and the main parameters to obtain the induced effects over the rest of the economic system. According to the most updated available figures, biotechnological activities would have directly generated almost 1,600 millions of euros in 2005, and they would be employed more than 9,000 workers. But if we take into account the full linkages with the rest of the system, the macroeconomic impact of Biotechnological activities would reach around 5,000 millions euros in production terms (0.6% of total GDP) and would be responsible, directly or indirectly, of more than 44,000 employments.

N-Benzothiazole-2-sulfonyl (Bts)-protected amino acid chlorides were used to prepare the hindered cyclosporin 8-11 tetrapeptide subunit 1. The synthesis was performed via 3a and the deprotected amines 5a, 13, and 19, including three repeated cycles involving N-methylation using iodomethane/potassium carbonate, deprotection of the Bts group, and N-acylation with a N-Bts-amino acid chloride such as 9b or 9c. Among three Bts cleavage methods compared (H3PO2/THF; NaBH4/EtOH; PhSH/K2CO3), the third gave somewhat higher overall yields. N-Acylation of 5a with the Bts-protected N-methylamino acid chloride 10b followed by deprotection was also highly efficient and could be used as an alternative route to 11. Each of the deprotected amines was isolated without chromatography using simple extraction methods to remove neutral byproducts. The tetrapeptide 1 was obtained in analytically pure form as the monohydrate.

Actin filaments align around myosin filaments in the correct polarity and in a hexagonal arrangement to form cross-striated structures. It has been postulated that this myosin-actin interaction is important in the initial phase of myofibrillogenesis. It was previously demonstrated that an inhibitor of actin-myosin interaction, BDM (2,3-butanedione monoxime), suppresses myofibril formation in muscle cells in culture. However, further study showed that BDM also exerts several additional effects on living cells. In this study, we further examined the role of actin-myosin interaction in myofibril assembly in primary cultures of chick embryonic skeletal muscle by applying a more specific inhibitor, BTS (N-benzyl-p-toluene sulphonamide), of myosin ATPase and actin-myosin interaction. The assembly of sarcomeric structures from myofibrillar proteins was examined by immunocytochemical methods with the application of BTS to myotubes just after fusion. Addition of BTS (10-50 microM) significantly suppressed the organization of actin and myosin into cross-striated structures. BTS also interfered in the organization of alpha-actinin, C-protein (or MyBP-C), and connectin (or titin) into ordered striated structures, though the sensitivity was less. Moreover, when myotubes cultured in the presence of BTS were transferred to a control medium, sarcomeric structures were formed in 2-3 days, indicating that the inhibitory effect of BTS on myotubes is reversible. These results show that actin-myosin interaction plays a critical role in the process of myofibrillogenesis.

A Methodology for Measuring Voice Quality Using PESQ and Interactive Voice Response in the GSM Channel Designed by OpenBTS

Full Text Available This article discusses a methodology for rating the quality of mobile calls. Majority telecommunications service from the perspective of the whole world is using mobile telephony networks. One of the problems affecting this service and its quality are landscape barriers, which prevent the spread signal. Price and complex construction of classic BTS does not allow their dense distribution. In such cases, one solution is to use OpenBTS technology. Design of OpenBTS is more available, so it can be applied to much more places and more complex points. Purpose of this measurement is a model for effective stations deployment, due to shape and distribution of local barriers that reduce signal power, and thus the quality of speech. GSM access point for our mobile terminals is OpenBTS USRP N210 station. The PESQ method for evaluating of speech quality is compared with the subjective evaluation, which provides Asterisk PBX with IVR call back. Measurement method was taken into account the call quality depending on terminal position. The measured results and its processing bring knowledge to use this technology for more complicated locations with degraded signal level and increases the quality of voice services in telecommunications.

2004-01-01

Long-term treatment of Parkinson's disease (PD) with levodopa (L-dopa) induces dyskinesia that, once established, is provoked by each dose of L-dopa or a dopamine (DA) agonist. In contrast, monoamine reuptake inhibitors may reverse motor deficits in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated primates without provoking established involuntary movements. We now examine whether the potent monoamine reuptake blocker BTS 74 398 induces established dyskinesia in MPTP-treated common marmosets primed previously with L-dopa and whether co-administration of BTS 74 398 with L-dopa potentiates motor behaviour and dyskinesia induced by acute L-dopa treatment. Administration of BTS 74 398 (2.5, 5.0, or 10.0 mg/kg, p.o.) in MPTP-treated common marmosets increased locomotor activity and reduced motor disability in a dose-related manner but did not provoke involuntary movements. BTS 74 398 (2.5, 5.0, or 10.0 mg/kg p.o.) co-administered with a threshold dose of L-dopa (2.5 mg/kg p.o.) did not evoke a motor response or induce dyskinesia. Similarly, concomitant administration of BTS 74 398 (5.0 mg/kg p.o.) with a submaximal L-dopa dose (12.5 mg/kg p.o.) did not potentiate the motor response produced by L-dopa alone and there was no alteration in the dyskinesia provoked by L-dopa challenge. BTS 74 398 reverses motor abnormalities in MPTP-treated marmosets without evoking established dyskinesia but no additive improvement occurs when administered in combination with L-dopa. The lack of synergy with L-dopa may suggest different sites of drug action. Copyright 2003 Movement Disorder Society

Healthcare biotechnology in India.

Biotechnology in India has made great progress in the development of infrastructure, manpower, research and development and manufacturing of biological reagents, biodiagnostics, biotherapeutics, therapeutic and, prophylactic vaccines and biodevices. Many of these indigenous biological reagents, biodiagnostics, therapeutic and prophylactic vaccines and biodevices have been commercialized. Commercially when biotechnology revenue has reached $25 billions in the U.S. alone in 2000 excluding the revenues of biotech companies that were acquired by pharmaceutical companies, India has yet to register a measurable success. The conservative nature and craze of the Indian Industry for marketing imported biotechnology products, lack of Government support, almost non-existing national healthcare system and lack of trained managers for marketing biological and new products seem to be the important factors responsible for poor economic development of biotechnology in India. With the liberalization of Indian economy, more and more imported biotechnology products will enter into the Indian market. The conditions of internal development of biotechnology are not likely to improve in the near future and it is destined to grow only very slowly. Even today biotechnology in India may be called to be in its infancy.

The study purpose was to investigate the direct effect of amitraz, a formamidine insecticide/acaricide, and its active metabolite BTS 27271 on insulin and glucagon secretion from the perfused rat pancreas. Amitraz and BTS 27271 (0.01, 0.1, 1, and 10 micromol/L) inhibited insulin secretion in a concentration-dependent manner. Amitraz increased glucagon secretion at 10 micromol/L, whereas BTS 27271 increased glucagon secretion at 1 and 10 micromol/L. Amitraz- and BTS 27271-induced decreases in insulin secretion and increases in glucagon secretion were not abolished during the 10-minute washout period. During the arginine treatment, both amitraz and BTS 27271 groups (0.1, 1, and 10 micromol/L) had lower insulin secretion and higher glucagon secretion than the control group. Idazoxan, an alpha2A/2D-adrenergic receptor (AR) antagonist, prevented the inhibitory effect of amitraz on insulin secretion in a concentration-dependent manner, but prazosin, an alpha1- and alpha2B/2C-AR antagonist, failed to antagonize the effect of amitraz. These results demonstrate that (1) amitraz and BTS 27271 inhibit insulin and stimulate glucagon secretion from the perfused rat pancreas, (2) amitraz inhibits insulin secretion by activation of alpha2D-ARs, since rats have alpha2D- but not alpha2A-ARs, and (3) amitraz and BTS 27271 may have a high binding affinity to the alpha2D-ARs of pancreatic islets.

The ISS Biotechnology Facility (BTF) platform provides scientists with a unique opportunity to carry out diverse experiments in a microgravity environment for an extended period of time. Although considerable progress has been made in preserving cells on the ISS for long periods of time for later return to Earth, future biotechnology experiments would desirably monitor, process, and analyze cells in a timely way on-orbit. One aspect of our work has been directed towards developing biochemical sensors for pH, glucose, oxygen, and carbon dioxide for perfused bioreactor system developed at Johnson Space Center. Another aspect is the examination and identification of new and advanced commercial biotechnologies that may have applications to on-orbit experiments.

Is the BTS/SIGN guideline confusing? A retrospective database analysis of asthma therapy.

The British guideline on the management of asthma produced by the British Thoracic Society (BTS) and the Scottish Intercollegiate Guidelines Network (SIGN) describes five steps for the management of chronic asthma. Combination therapy of a long acting β2-agonist (LABA) and an inhaled corticosteroid (ICS) is recommended as first-line therapy at step 3, although the dose of ICS at which to add a LABA is subject to debate. To classify the inhaled therapy prescribed to patients with asthma in NHS Forth Valley according to two interpretations of the BTS/SIGN guideline and to evaluate the use of combination therapy in this population. A retrospective analysis including patients from 46 general practitioner surgeries was conducted. Patients with physician diagnosed asthma were classified according to the BTS/SIGN guideline based on treatment prescribed during 2008. Patient characteristics were evaluated for the overall step classification, and specifically for therapy in step 3. 12,319 patients were included. Guideline interpretation resulted in a shift of 9.2% of patients (receiving medium-dose ICS alone) between steps 2 and 3. The largest proportion of patients (32.3%) was classified at step 4. Age, sex, smoking status, chronic obstructive pulmonary disease co-morbidity, and utilisation of short-acting β2-agonists and oral corticosteroids all correlated with step; however, no differences in these characteristics were evident between low-dose combination therapy and medium-dose ICS alone at step 3. Further studies are needed to evaluate prescribing decisions in asthma. Guideline recommendations regarding the use of ICS dose escalation versus combination therapy need to be clarified relative to the published evidence.

Despite their usefulness for mankind, many of microorganisms are generally emphasized of the aspect of their harmfulness as decomposable and pathogenic microorganisms, apt to implant people with wrong preconception. Moreover, the food industries have a habitual practice that they leave unexpectedly unclean conditions unattended. This paper indicates such actual circumstances by quoting various examples, and introduces characteristics and test results on commercially available chemicals having excellent cleansing and sterilizing effects. High-pressure and high-temperature sterilization processes fit the purpose of preservation, but secondary contamination may occur in subsequent processing, for example, from the ceiling and walls of a work room, or operators' fingers. Problems exist there that should be considered in biotechnological clean systems. Technologies have been advanced that mix a small amount of chemicals into plastic sheets, wall materials, and floor materials so that their surfaces are kept away from growth of microorganisms for extended periods of time. About 300 kinds of chemicals have been developed, and are available commercially. 3 refs., 8 figs.

Full Text Available Biotechnology as a science includes various aspects of the management and manipulation of biological systems. Recent advances in immunology, molecular biology, cell culture and other associated areas provide an opportunity for scientists to move biology out of the laboratory and into the realms of society. This has many implications which mankind on a whole may not be prepared to cope with at this time. This new capability has been referred to as "Biotechnology". Biotechnology has also been defined as "the integrated use of biochemistry, microbiology, and chemical engineering in order to achieve the capacities of microbes and culture cells". Genetic engineering which includes gene splicing and recombinant DNA-cloning is an example of a recent offshoot of biotechnology. Because of the advent of biotechnology, one can now think of the prospect of engineering tomorrows vaccines. In the past, vaccine development has been laborious and in many instances an unrewarding task. After years of effort only a handful of safe, effective vaccines have emerged. In the biotechnology arena, new methodologies and strategies for immunizing humans and domestic animals against infectious diseases are providing new hope for discovering successful vaccines. While most of the effort in the past has focused on viral vaccine development, attention is now being directed towards vaccines for protection against parasitic diseases. Currently, considerable effort is being made to develop vaccines for malaria, coccidiosis (in fowl, cholera, malaria, schistosomiasis and trypanosomiasis among others.

The present study investigated whether substitution of HEPES for bicarbonate in BTS (BTS-H) used to dilute boar ejaculates immediately after ejaculation could reduce the increased inducibility of the acrosome reaction by calcium and calcium ionophore A23187. When an ejaculate was split, diluted 5-fold with regular BTS (BTS-B) and BTS-H and stored at 17 C for 12 h or 60 h, the extender or storage time had no significant influence on sperm motility or viability measured by the eosin-nigrosin method. When spermatozoa diluted serially with BTS-B and stored (36 h) were stimulated with Ca2+ (3 mM) and A23187 (0.3 microM), the proportion of spermatozoa that underwent the acrosome reaction (% acrosome reactions) significantly increased as the magnifications of dilution increased (bicarbonate content almost unchanged by dilution). By contrast, the % acrosome reactions in spermatozoa similarly diluted and stored with BTS-H decreased with the increasing magnifications of dilution (bicarbonate decreased). Sperm motility immediately after the end of incubation without A23178 tended to be lower for BTS-H than BTS-B, and the ejaculates for BTS-H had a tendency to have a lower total protein in seminal plasma than those for BTS-B. These results implied that the samples for BTS-H could be used as a model for ejaculates possibly collected during summer and showing subfertility. When an ejaculate was split, diluted serially with BTS-B and BTS-H and stored, viability measured by staining with propidium iodide was extremely similar between the 2 extenders and among the different dilution magnifications, regardless of whether spermatozoa were washed (stored for 36-66 h) or not (stored for 66-72 h). These results suggest that boar ejaculate can be stored with BTS-H at least according to the results for sperm motility and viability and that hypersensitivity of spermatozoa to Ca2+ and A23187 potentially associated with boar subfertility could be lessened by diluting ejaculates with BTS-H.

Full Text Available The Iguape Bay (12º00’ – 13º00’S and 38º30’ – 39º30’ is an estuary located at the mouth of the Paraguaçu River, inside Todos os Santos Bay (BTS, in Bahia, Brazil. It is 30km downstream from the Pedra do Cavalo Dam, which is the second largest dam in Brazil. The water in Iguape Bay is influenced by ocean tides originating from the BTS and the discharge of the Paraguaçu River. The effects of the currents as well as the variation in the outflow from the Pedra do Cavalo Dam have intensified the natural stress of this paralic environment. The main goal of this study was to investigate the distribution of Thecamoeba species present in the bottom sediments of Iguape Bay, in order to produce data that can be used to interpret the processes operating in this ecologically complex environment. The density of the living and dead species of Thecamoeba was determined by the volume of sediment collected, and the diversity index, constancy, evenness and richness of Thecamoeba were calculated. Sedimentological analyses were also performed in order to classify sediment types in the selected profiles.

The costly benefits of opposing agricultural biotechnology.

Science.gov (United States)

Apel, Andrew

2010-11-30

Rigorous application of a simple definition of what constitutes opposition to agricultural biotechnology readily encompasses a wide array of key players in national and international systems of food production, distribution and governance. Even though the sum of political and financial benefits of opposing agricultural biotechnology appears vastly to outweigh the benefits which accrue to providers of agricultural biotechnology, technology providers actually benefit from this opposition. If these barriers to biotechnology were removed, subsistence farmers still would not represent a lucrative market for improved seed. The sum of all interests involved ensures that subsistence farmers are systematically denied access to agricultural biotechnology. Copyright © 2010 Elsevier B.V. All rights reserved.

This study questions the presumed relation between formal schooling and scientific literacy about biotechnologies. Comparing science and nonscience majors' knowledge of and attitudes toward biotechnological applications, conclusions are drawn if their formal learnings improve pupils' understandings of and attitudes toward biotechnology applications. Sample of the study consists of 403 undergraduate and graduate students, 198 nonscience, and 205 science majors. The Biotechnology Knowledge Questionnaire and the Biotechnology Attitude Questionnaire were administered. Descriptive statistics (mean and percentages), t test, and correlations were used to examine the participants' knowledge of biotechnology and attitudes toward biotechnological applications and differences as regards their majors. Although the science majors had higher knowledge and attitude scores than the nonscience majors, it is not possible to say that they have sufficient knowledge of biotechnologies. Besides, the participants' attitudes toward biotechnological applications were not considerably related to their knowledge of biotechnology. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):115-125, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

The application of biotechnology is a potential tool for mitigating the present and future fooding and clothing demands in developing countries like India. The commercialization of biotechnological products might benefiting the poor`s in developing countries are unlikely to be developed. Biotechnology has the potential to provide a wide range of products and the existing production skills in the industrial, pharmaceuticals and the agricultural sector. Ownership of the intellectual property rights is the key factors in determining the success of any technological invention, which was introduced in the market. It provides the means for technological progress to continue of the industry of the country. The new plans, animal varieties, new methods of treatments, new crops producing food articles as such are the inventions of biotechnology. Biotechnology is the result of the application of human intelligence and knowledge to the biological processes. Most of the tools of biotechnology have been developed, by companies, governments, research in- stitutes and universities in developed nations. These human intellectual efforts deserve protection. India is a developing country with advance biotechnology based segments of pharmaceutical and agricultural industries. The Trade Related Intellectual Property Rights (TRIPS) is not likely to have a significant impact on incentives for innovation creation in the biotechnology sectors. In the recent years, the world has seen the biotechnology sector as one of greatest investment area through the Patent Law and will giving huge profit in future. The Research and Development in the field of biotechnology should be encouraged for explor- ing new tools and improve the biological systems for interest of the common people. Priority should be given to generation, evaluation, protection and effective commercial utilization of tangible products of intellectual property in agriculture and pharmaceuticals.

In recent years, by tremendous use of mobile phone telecommunication, a growing concern about the possible health hazards has increased greatly among public and scientists. The mobile phone exposure has been shown to have many effects upon the immune functions, stimulating hormones, mammalian brain, sperm motility and morphology, and neurological pathologies syndrome. The aim of this study was to find out the psychological and psychobiological reactions of the people who are living near mobile phone base transceiver stations (BTS) antenna, in Isfahan, Iran. A cross-sectional study on 250 randomly selected inhabitants (133 women and 117 men) was performed in October 2012 till November 2012. The inhabitants were requested to complete a standardized questionnaire that focused on the relevant psychological and psychobiological reactions parameters. A computer program (SPSS version16.0, Chicago, IL) was used for statistical analysis using the Chi-square test with Yates correction. All the data were tested using a criterion level of p = 0.05. The results showed that most of the symptoms such as nausea, headache, dizziness, irritability, discomfort, nervousness, depression, sleep disturbance, memory loss and lowering of libido were statistically significant in the inhabitants living near the BTS antenna (300 m). It is suggested that cellular phone BTS antenna should not be sited closer than 300 m to populations to minimize exposure of neighbors.

Role of Biotechnology in Animal Production Systems in Hot Climates

Directory of Open Access Journals (Sweden)

P. J. Hansen

1996-01-01

Full Text Available Developments in the biological sciences in the last three decades have revolutionized mankind's ability to manipulate the genetics, cell biology and physiology of biological organisms. These techniques, collectively termed biotechnology, create the opportunity for modifying domestic animals in ways that markedly increase the efficiency of production. Among the procedures being developed for animal production systems are marker-assisted selection of specific alleles of a gene that are associated with high production, production of transgenic animals , super ovulation and embryo transfer, in vitro fertilization, embryo sexing and cloning, production of large amounts of previously-rare proteins through use of genetically -engineered bacteria or other cells, and identification of new biologically-active molecules as potential regulators of animal function. To date, most uses of biotechnology have concentrated on problems of general relevance to animal agriculture rather than specific problems related to livestock production in hot climates. However, it is likely that biotechnology will be used for this latter purpose also. Strategies to increase disease resistance using marker-assisted selection, production of transgenic animals expressing viral proteins, and recombinant cytokines to enhance immune function should prove useful to reducing the incidence and seventy of various tropical diseases. Additionally, there are methods to reduce effects of heat stress on oestrus detection and establishment of pregnancy. These include remote sensing of oestrus, ovulation synchronization systems and embryo transfer. More research regarding the physiological processes determining heat tolerance and of the pathways through which heat stress alters physiological function will be required before molecular biology techniques can be used to reduce the adverse effects of heat stress on animal production.

2014-08-01

While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

Full Text Available Aquaculture is gaining commendable importance to meet the required protein source for ever increasing human population. The aquaculture industry is currently facing problems on developing economically viable production systems by reducing the impact on environment. Sustainable and enhanced fish production from aquaculture may be better achieved through application of recent biotechnological innovations. Utilisation of transgenic technology has led to production of fishes with faster growth rate with disease resistance. The full advantage of this technology could not be achieved due to concern of acceptance for Genetically Modified Organisms (GMOs. The biotechnological intervention in developing plant based feed ingredient in place of fish meal which contain high phosphorus is of prime area of attention for fish feed industry. The replacement of fish meal will also reduce fish feed cost to a greater extent. Year round fish seed production of carps through various biotechnological interventions is also need of the hour. This paper discusses technical, environmental and managerial considerations regarding the use of these biotechnological tools in aquaculture along with the advantages of research application and its commercialization.

Cognitive impairment occurs frequently in post-stroke patients. This study aimed to determine the effects of a virtual reality training (VRT) with BTs-Nirvana (BTsN) on the recovery of cognitive functions in stroke patients, using the Interactive-Semi-Immersive Program (I-SIP). We enrolled 12 subjects (randomly divided into two groups: experimental group (EG); and control group (CG)), who attended the Laboratory of Robotic and Cognitive Rehabilitation of IRCCS Neurolesi of Messina from January to June 2016. The EG underwent a VRT with BTsN, whereas CG received a standard cognitive treatment. Both the groups underwent the same conventional physiotherapy program. Each treatment session lasted 45 minutes and was repeated three times a week for 8 weeks. All the patients were evaluated by a specific clinical-psychometric battery before (T0), immediately (T1), and one month (T2) after the end of the training. At T1, the EG presented a greater improvement in the trunk control test (p = 0.03), the Montreal Cognitive Assessment (p = 0.01), the selective attention assessment scores (p = 0.01), the verbal memory (p = 0.03), and the visuospatial and constructive abilities (p = 0.01), as compared to CG. Moreover, such amelioration persisted at T2 only in the EG. According to these preliminary data, VRT with I-SIP can be considered a useful complementary treatment to potentiate functional recovery, with regard to attention, visual-spatial deficits, and motor function in patients affected by stroke.

A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, sustainable, and environmentally friendly microbial biocements and biogrouts for the construction ground improvement. The microbial polysaccharides are used as admixtures for cement. Microbially produced biodegradable bioplastics can be used for the temporarily constructions. The bioagents that are used in construction biotechnologies are either pure or enrichment cultures of microorganisms or activated indigenous microorganisms of soil. The applications of microorganisms in the construction processes are bioaggregation, biocementation, bioclogging, and biodesaturation of soil. The biotechnologically produced construction materials and the microbially-mediated construction technologies have a lot of advantages in comparison with the conventional construction materials and processes. Proper practical implementations of construction biotechnologies could give significant economic and environmental benefits.

Biotechnology: challenges and prospects

Rapidly occurring technological breakthroughs in the wake of numerous discoveries in different fields, such as biochemistry, genetic engineering as well as cellular and molecular biology as described in this paper have a variety of industrial applications, and forcasts covering these and various other fields have been made. The emerging bio-industry, covering diverse industries, such as chemical, food, pharmaceutical, etc., as well as the domains of health, environmental protection and abatement of pollution present challenging prospects. Several biotechnology processes relating to bioenergy, fermentation, waste transformation, vaccines, etc. are of particular interest to the developing countries. The 'functioning systems' resulting from the breakthrouth in genetic engineering, entailing extraordinary refinement of analytical techniques and technological progress, pose the challenging task of harnessing them to the advantage of mankind. Providing effective legal protection, conducive to the development of biotechnologies-their innovative process and technological change-is a matter of serious concern, involving practical and economical considerations. Several other issues and questions, such as risk prevention and management of potential dangers and hazards in genetic recombination operation by way of safety regulations and necessary guidelines, questions relating to the clinical trials of the interferons-the wonder drug-as well as questions of professional ethics are raised by biotechnologies. Industry-funded research in biotechnology, where scientific and commercial imperatives are interlocked, has for instance, its repercussions on the traditional thrust of university system, specially the sanctity of autonomy for basic research.

Modern biotechnology is one of the most important scientific and technological revolutions in the 21st century, with an increasing and measurable impact on society. Development of biotechnology curriculum has become important to high school bioscience classrooms. This study has monitored high school students in Taiwan on their knowledge of and attitudes towards biotechnology for nearly two decades. Not surprisingly, knowledge of biotechnology of current students has increased significantly (p students have learned some definitions and examples of biotechnology. There was a positive correlation between biotechnology knowledge and attitudes toward biotechnology for current students who study Advanced Biology (AB). However, for current students who did not study AB, there was a negative correlation.The attitude results showed that students today expressed less favorable opinions toward agricultural biotechnology (p students today and 18 years ago in opinions towards medical biotechnology. In addition, current students showed a greater concern involving environmental risks than former students. Interestingly, the high school curriculum did affect students' attitudes toward genetically engineered (GE) plants but not GE animals. Our current study also found that the students' attitude towards GE animals was influenced more by their limited knowledge than by their moral belief. On the basis of findings from this study, we suggest that more materials of emerging animal biotechnology should be included in high school curriculum and recommend that high school teachers and university faculty establish a collaborative framework in the near future. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(5):475-491, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

This study proposes a control system for permanent magnet DC (PMDC) motor. PMDC drive control system has two critical parameters: control and monitoring. Control system includes rotation speed control and direction of rotation of motor using motor drive module BTS7960. The PWM signal has a fixed frequency of waves with varying duty cycles (between 0% and 100%), so the motor rotation can be regulated gradually using a potentiometer already programmed on the Arduino Uno board. The motor rotation direction setting uses the H-bridge circuit method using a 3-way switch to set the direction of forward-reverse rotation of the motor. The monitoring system includes measurements of rotational speed, current, and voltage. Motor rotation speed can be adjusted from the armature voltage settings through the duty cycle PWM setting so that the motor speed can be increased or decreased by the desired duty cycle. From the unload PMDC motor test results it has also been shown that the torque of the motor is relatively constant when there is a change in speed from low rpm to high rpm or vice versa.

2003-01-01

Aboard the International Space Station (ISS), the Tissue Culture Medium (TCM) is the bioreactor vessel in which cell cultures are grown. With its two syringe ports, it is much like a bag used to administer intravenous fluid, except it allows gas exchange needed for life. The TCM contains cell culture medium, and when frozen cells are flown to the ISS, they are thawed and introduced to the TCM through the syringe ports. In the Cellular Biotechnology Operations Support System-Fluid Dynamics Investigation (CBOSS-FDI) experiment, several mixing procedures are being assessed to determine which method achieves the most uniform mixing of growing cells and culture medium.

Mandenius, Carl-Fredrik; Björkman, Mats

2010-05-01

Traditionally, biotechnology design has focused on the manufacture of chemicals and biologics. Still, a majority of biotechnology products that appear on the market today is the result of mechanical-electric (mechatronic) construction. For these, the biological components play decisive roles in the design solution; the biological entities are either integral parts of the design, or are transformed by the mechatronic system. This article explains how the development and production engineering design principles used for typical mechanical products can be adapted to the demands of biotechnology products, and how electronics, mechanics and biology can be integrated more successfully. We discuss three emerging areas of biotechnology in which mechatronic design principles can apply: stem cell manufacture, artificial organs, and bioreactors. Copyright 2010 Elsevier Ltd.

The purpose of our study was to determine the effect of dilution and liquid-preservation of boar sperm on oxidoreductive capability of their mitochondria. The semen was diluted with BTS extender produced from water purified by destillation or by reverse osmosis. The spermatozoa were stored over a four-day period at 16-18 degrees C. The function of sperm mitochondria was assessed using the screening cytochemical test for NADH-dependent oxidoreductases (diaphorase/NADH, related to flavoprotein). Morphological assessment of cytochemical reaction was carried out using a light microscope. The intensity of the reaction was evaluated by means of a computer image analysing system (Quantimet 600S), measuring the integrated optical density (IOD) and mean optical density (MOD) of the reaction product (formazans) occurring in the sperm midpieces. In the non-diluted semen, intensive cytochemical reaction throughout the length of the sperm midpiece was observed. Furthermore, spermatozoa with the intensive reaction displayed the high optical density values. After dilution the semen with two variants of experimental extender, and as the conservation time expired, the cytochemical reaction was less intensive. Moreover, the absence of formazan deposits in various parts of the sperm midpiece was also noted. These morphological features corresponded to low values of optical density. These findings suggest that the dilution of semen and the time of sperm preservation may be critical factors that handicap energy metabolism of sperm mitochondria. The type of water used in preparing BTS extender does not have any significant effect on the oxidoreductive capability of sperm boar mitochondria.

Comparative analysis of LytS/LytTR-type histidine kinase/response regulator systems in γ-proteobacteria.

Full Text Available Bacterial histidine kinase/response regulator systems operate at the interface between environmental cues and physiological states. Escherichia coli contains two LytS/LytTR-type histidine kinase/response regulator systems, BtsS/BtsR (formerly YehU/YehT and YpdA/YpdB, which have been identified as pyruvate-responsive two-component systems. Since they exhibit remarkable similarity, we analyzed their phylogenetic distribution within the γ-proteobacteria, and experimentally characterized them in a set of representative species. We found that BtsS/BtsR is the predominant LytS/LytTR-type two-component system among γ-proteobacteria, whereas YpdA/YpdB primarily appears in a supplementary role. Based on our observations in E. coli, we used the highly conserved DNA-binding motifs to test the in vivo functionality of both systems in various genera, including Salmonella, Enterobacter, Citrobacter, Xenorhabdus, Yersinia, Aeromonas and Vibrio. The results suggest that, in all cases tested, BtsS/BtsR and YpdA/YpdB respond to different levels of pyruvate in the environment.

Boh, B

1996-09-01

The success of biotechnological research, development and marketing depends to a large extent on the international transfer of information and on the ability to organise biotechnology information into knowledge. To increase the efficiency of information-based approaches, an information strategy has been developed and consists of the following stages: definition of the problem, its structure and sub-problems; acquisition of data by targeted processing of computer-supported bibliographic, numeric, textual and graphic databases; analysis of data and building of specialized in-house information systems; information processing for structuring data into systems, recognition of trends and patterns of knowledge, particularly by information synthesis using the concept of information density; design of research hypotheses; testing hypotheses in the laboratory and/or pilot plant; repeated evaluation and optimization of hypotheses by information methods and testing them by further laboratory work. The information approaches are illustrated by examples from the university-industry joint projects in biotechnology, biochemistry and agriculture.

We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

Brandt, F.

1993-01-01

It is shown that Baecklund transformations (BTs) and zero-curvature representations (ZCRs) of systems of partial differential equations (PDEs) are closely related. The connection is established by nonlinear representations of the symmetry group underlying the ZCR which induce gauge transformations relating different BTs. This connection is used to construct BTs from ZCRs (and vice versa). Furthermore a procedure is outlined which allows a systematic search for ZCRs of a given system of PDEs. (orig.)

Full Text Available The development of molecular biology and molecular genetics, especially of the recombinant DNA technology enabled improvement of experimental methods that provide manipulation within a cell-free system, such as cell and tissue cultures. Such methods resulted in the development of different new technologies with specific properties in relation to the conventional definitions. According to PERSLEY and lantin (2000 the following components are essential for the contemporary biotechnology: (i genomics - a molecular characterization of all genes and gene products of an organism (ii bioinformatics - the assembly of data from genomic analysis into accessible forms; (iii transformation - the introduction of genes controlling a trait of interest into a genome of a desired organism (micro organisms, plants, animal systems. By the application of cotemporary biotechnology new methods in the field of diagnostic are developed such as rapid and more accurate identification of the presence and absence of genes in the genome of the organism of interest (identification of pathogens prenatal diagnostics, molecular markers assisted breeding for plants, etc. The traits of an organism are determined by its genetic material, i.e. by a molecule of deoxyribonucleic acid (DNA. watson and crick (1953 were the first scientists to describe the structure of DNA as a double-stranded helix. Higher organisms contain a set of linear DNA molecules - chromosomes and a full set of chromosomes of an organism is a genome. Each genome is divided into a series of functional units, i.e. genes. The traits of an organism depend on genes, but their expression depends not only on genes but also on many other factors, including whether a gene, controlling the trait, expresses, specific cells in which it expresses and specially the mode by which the gene and its product interact with the environment. A special aspect within the application of biotechnology occurs as an interaction of a

Compared to emergency surgery, self-expandable metallic stents are effective and safe when used as bridge-to-surgery (BTS) in operable patients with acute colorectal cancer obstruction. In this study, we report data on the new conformable colonic stents. To evaluate clinical effectiveness of conformable stents as BTS in patients with acute colorectal cancer obstruction. This was a retrospective study. The study was conducted at six Italian Endoscopic Units. Data about patients with acute malignant colorectal obstruction were collected between 2007 and 2012. All patients were treated with conformable stents as BTS. Technical success, clinical success, rate of primary anastomosis and colostomy, early and late complications were evaluated. Data about 88 patients (62 males) were reviewed in this study. Conformable SEMS were correctly deployed in 86 out of 88 patients, with resolution of obstruction in all treated patients. Tumor resection with primary anastomosis was possible in all patients. A temporary colostomy was performed in 40. Early complications did not occur. Late complications occurred in 11 patients. Stent migration was significantly higher in patients treated with partially-covered stents compared to the uncovered group (35% vs. 0%, P<0.001). Endoscopical re-intervention was required in 12% of patients. One patient with rectal cancer had an anastomotic dehiscence after surgery and he was successfully treated with endoscopic clipping. One year after surgery, all patients were alive and local recurrence have not been documented. This was a retrospective and uncontrolled study. Preliminary data from this large case series are encouraging, with a high rate of technical and clinical success and low rate of clinically relevant complications. Partially-covered SEMS should be avoided in order to reduce the risk of endoscopic re-intervention. Copyright © 2016. Published by Elsevier Masson SAS.

Chambergo, Felipe S; Valencia, Estela Y

2016-03-01

Fungal habitats include soil, water, and extreme environments. With around 100,000 fungus species already described, it is estimated that 5.1 million fungus species exist on our planet, making fungi one of the largest and most diverse kingdoms of eukaryotes. Fungi show remarkable metabolic features due to a sophisticated genomic network and are important for the production of biotechnological compounds that greatly impact our society in many ways. In this review, we present the current state of knowledge on fungal biodiversity, with special emphasis on filamentous fungi and the most recent discoveries in the field of identification and production of biotechnological compounds. More than 250 fungus species have been studied to produce these biotechnological compounds. This review focuses on three of the branches generally accepted in biotechnological applications, which have been identified by a color code: red, green, and white for pharmaceutical, agricultural, and industrial biotechnology, respectively. We also discuss future prospects for the use of filamentous fungi in biotechnology application.

The monoamine uptake inhibitor BTS 74 398 induces ipsilateral circling in 6-hydroxydopamine (6-OHDA) lesioned rats without induction of abnormal motor behaviours associated with L-dopa administration. We examined whether this was reflected in the expression of peptide mRNA in the direct and indirect striatal output pathways.6-OHDA lesioning of the nigrostriatal pathway increased striatal expression of PPE-A mRNA and decreased levels of PPT mRNA with PPE-B mRNA expression remaining unchanged. Acute L-dopa administration normalised PPE-A mRNA and elevated PPT mRNA while PPE-B mRNA expression remained unchanged. Acute administration of BTS 74 398 did not alter striatal peptide mRNA levels. Following chronic treatment with L-dopa, PPE-A mRNA expression in the lesioned striatum continued to be normalised and PPT mRNA was increased compared to the intact side. PPE-B mRNA expression was also markedly increased relative to the non-lesioned striatum. Chronic BTS 74 398 administration did not alter mRNA expression in the 6-OHDA lesioned striatum although small increases in PPT mRNA expression in the intact and sham lesioned striatum were observed. The failure of BTS 74 398 to induce changes in striatal neuropeptide mRNA correlated with its failure to induce abnormal motor behaviours or behavioural sensitisation but does not explain how it produces a reversal of motor deficits. An action in another area of the brain appears likely and may explain the subsequent failure of BTS 74 398 and related compounds to exert anti-parkinsonian actions in man.

Full Text Available Biotechnology is the knowledge and techniques of developing and using biological systems for deriving special products and services. The age-old technology took a new turn with the advent of recombinant DNA techniques, and boosted by the development of other molecular biological techniques, cell culture techniques and bioinformatics. Medical biotechnology is the major thrust area of biotechnology. It has brought revolutions in medicine – quick methods for diagnosing diseases, generation of new drugs and vaccines, completely novel approach of treatment are only a few to mention. The industrial and financial bulk of the industry mushroomed very rapidly in the last three decades, led by the USA and western advanced nations. Asian countries like China, India, South Korea, Taiwan and Singapore joined late, but advancing forward in a big way. In all the Asian countries governments supported the initiatives of the expert and entrepreneur community, and invested heavily in its development. Bangladesh has got great potential in developing biotechnology and reaping its fruits. However, lack of commitment and patriotism, and too much corruption and irresponsibility in political and bureaucratic establishment are the major hindrance to the development of biotechnology in Bangladesh.

The purpose of this review is to survey current, emerging and predicted future biotechnologies which are impacting, or are likely to impact in the future on the life sciences, with a projection for the coming 20 years. This review is intended to discuss current and future technical strategies, and to explore areas of potential growth during the foreseeable future. Information technology approaches have been employed to gather and collate data. Twelve broad categories of biotechnology have been identified which are currently impacting the life sciences and will continue to do so. In some cases, technology areas are being pushed forward by the requirement to deal with contemporary questions such as the need to address the emergence of anti-microbial resistance. In other cases, the biotechnology application is made feasible by advances in allied fields in biophysics (e.g. biosensing) and biochemistry (e.g. bio-imaging). In all cases, the biotechnologies are underpinned by the rapidly advancing fields of information systems, electronic communications and the World Wide Web together with developments in computing power and the capacity to handle extensive biological data. A rationale and narrative is given for the identification of each technology as a growth area. These technologies have been categorized by major applications, and are discussed further. This review highlights: Biotechnology has far-reaching applications which impinge on every aspect of human existence. The applications of biotechnology are currently wide ranging and will become even more diverse in the future. Access to supercomputing facilities and the ability to manipulate large, complex biological datasets, will significantly enhance knowledge and biotechnological development.

New environmental pollutants interfere with the environment and human life along with technology development. One of these pollutants is electromagnetic field. This study determines the vertical microwave radiation pattern of different types of Base Transceiver Station (BTS) antennae in the Hashtgerd city as the capital of Savojbolagh County, Alborz Province of Iran. The basic data including the geographical location of the BTS antennae in the city, brand, operator type, installation and its height was collected from radio communication office, and then the measurements were carried out according to IEEE STD 95. 1 by the SPECTRAN 4060. The statistical analyses were carried out by SPSS16 using Kolmogorov Smirnov test and multiple regression method. Results indicated that in both operators of Irancell and Hamrah-e-Aval (First Operator), the power density rose with an increase in measurement height or decrease in the vertical distance of broadcaster antenna. With mix model test, a significant statistical relationship was observed between measurement height and the average power density in both types of the operators. With increasing measuring height, power density increased in both operators. The study showed installing antennae in a crowded area needs more care because of higher radiation emission. More rigid surfaces and mobile users are two important factors in crowded area that can increase wave density and hence raise public microwave exposure.

The rise (and decline?) of biotechnology.

Science.gov (United States)

Kinch, Michael S

2014-11-01

Since the 1970s, biotechnology has been a key innovator in drug development. An analysis of FDA-approved therapeutics demonstrates pharmaceutical companies outpace biotechs in terms of new approvals but biotechnology companies are now responsible for earlier-stage activities (patents, INDs or clinical development). The number of biotechnology organizations that contributed to an FDA approval began declining in the 2000s and is at a level not seen since the 1980s. Whereas early biotechnology companies had a decade from first approval until acquisition, the average acquisition of a biotechnology company now occurs months before their first FDA approval. The number of hybrid organizations that arise when pharmaceutical companies acquire biotechnology is likewise declining, raising questions about the sustainability of biotechnology.

Mladenović-Drinić Snežana

2004-01-01

Full Text Available Maize is one of the most important economic crops and the best studied and most tractable genetic system among monocots. The development of biotechnology has led to a great increase in our knowledge of maize genetics and understanding of the structure and behaviour of maize genomes. Conventional breeding practices can now be complemented by a number of new and powerful techniques. Some of these often referred to as molecular methods, enable scientists to see the layout of the entire genome of any organism and to select plants with preferred characteristics by "reading" at the molecular level, saving precious time and resources. DNA markers have provided valuable tools in various analyses ranging from phylogenetic analysis to the positional cloning of genes. Application of molecular markers for genetic studies of maize include: assessment of genetic variability and characterization of germ plasm, identification and fingerprinting of genotypes, estimation of genetic distance, detection of monogamic and quantitative trait loci, marker assisted selection, identification of sequence of useful candidate genes, etc. The development of high-density molecular maps which has been facilitated by PCR-based markers, have made the mapping and tagging of almost any trait possible and serve as bases for marker assisted selection. Sequencing of maize genomes would help to elucidate gene function, gene regulation and their expression. Modern biotechnology also includes an array of tools for introducing or deieting a particular gene or genes to produce plants with novel traits. Development of informatics and biotechnology are resulted in bioinformatic as well as in expansion of microarrey technique. Modern biotechnologies could complement and improve the efficiency of traditional selection and breeding techniques to enhance agricultural productivity.

Effects of Butyltins (BTs) on Mitogen-Activated-Protein Kinase Kinase Kinase (MAP3K) and Ras Activity in Human Natural Killer Cells

Science.gov (United States)

Celada, Lindsay J.; Whalen, Margaret M.

2013-01-01

Butyltins (BTs) contaminate the environment and are found in human blood. BTs, tributyltin (TBT) and dibutyltin (DBT), diminish the cytotoxic function and levels of key proteins of human natural killer (NK) cells. NK cells are an initial immune defense against tumors, virally-infected cells and antibody-coated cells and thus critical to human health. The signaling pathways that regulate NK cell functions include mitogen-activated protein kinases (MAPKs). Studies have shown that exposure to BTs leads to the activation of specific MAPKs and MAPK kinases (MAP2Ks) in human NK cells. MAP2K kinases (MAP3Ks) are upstream activators of MAP2Ks, which then activate MAPKs. The current study examined if BT-induced activation of MAP3Ks was responsible for MAP2K and thus, MAPK activation. This study examines the effects of TBT and DBT on the total levels of two MAP3Ks, c-Raf and ASK1, as well as activating and inhibitory phosphorylation sites on these MAP3Ks. In addition, the immediate upstream activator of c-Raf, Ras, was examined for BT-induced alterations. Our results show significant activation of the MAP3K, c-Raf, in human NK cells within 10 minutes of TBT exposure and the MAP3K, ASK1, after one hour exposures to TBT. In addition, our results suggest that both TBT and DBT are impacting the regulation of c-Raf. PMID:24038145

The biotechnology innovation machine: a source of intelligent biopharmaceuticals for the pharma industry--mapping biotechnology's success.

The marriage of biotechnology and the pharmaceutical industry (pharma) is predicated on an evolution in technology and product innovation. It has come as a result of advances in both the science and the business practices of the biotechnology sector in the past 30 years. Biotechnology products can be thought of as "intelligent pharmaceuticals," in that they often provide novel mechanisms of action, new approaches to disease control, higher clinical success rates, improved patient care, extended patent protection, and a significant likelihood of reimbursement. Although the first biotechnology product, insulin, was approved just 32 years ago in 1982, today there are more than 200 biotechnology products commercially available. Research has expanded to include more than 900 biotechnology products in clinical trials. Pharma is substantially engaged in both the clinical development of these products and their commercialization.

Full Text Available Summary. The article presents data on the development of technology and qualitative research, bio-products «Healing-1». One of the promising directions in food biotechnology is the development of new integrated starter-based consortia of microorganisms, which have higher activity compared with cultures prepared using pure cultures. So it was interesting studies on the development of new biotechnology and bio-based microbial consortium of lactic acid bacteria. Based on the analysis of biotechnological properties of native cultures created a new consortium of microorganisms containing lactic acid streptococci and bacilli, allowing the maximum extent possible to implement the physiological, biochemical and technological potential of microorganisms. Scientifically substantiated and experimentally developed a new biotechnology production of bioproducts «Healing-1», obtained on the basis of microbial consortium with broad spectrum antimicrobial activity. Experimentally investigated quality parameters of organic food «Healing-1» using a new microbial consortium as freshly prepared and during storage. Found that antagonistic activity of microflora bio «Healing-1» with respect to pathogenic and conditionally pathogenic bacteria, as well as its resistance to substances in the gastrointestinal tract of man is more pronounced compared to bioproducts obtained using a separate starter, members of the microbial consortium. It should be noted a more pronounced synthesis of exopolysaccharides in bioproduct «Healing-1», which leads to increased viscosity of the system and improves the consistency of bio. New bioproducts have good organoleptic characteristics and contain a high number of viable cells of lactic acid bacteria. High stability and survival of lactic acid bacteria during storage. In the study of attacked proteins bioproducts digestive proteinases «in vitro» found that the fermentation of milk microbial consortium increases the digestibility

Biotechnology education as social and cultural production/reproduction of the biotechnology community

Science.gov (United States)

Andrée, Maria

2014-03-01

This paper is a commentary to a paper by Anne Solli, Frank Bach and Björn Åkerman on how students at a technical university learn to argue as biotechnologists. Solli and her colleagues report from an ethnographic study performed during the first semester of a 5-year program in biotechnology at a technical university in Sweden. Their study demonstrates how students begin to acquire `the right way' of approaching the controversial issue of producing and consuming genetically modified organisms. In my response I discuss the ethnographic account of this particular educational practice in terms of social and cultural production/reproduction of a biotechnology community and how the participants (students and teaching professors) deal with the dialectic of individual and collective transformation. In the perspective of the biotechnology community, the work done by the teaching professor becomes a way of ensuring the future of the biotechnology community in terms of what values and objectives are held highly in the community of practice.

[Health risks in the biotechnological industry].

Science.gov (United States)

Colombi, A; Maroni, M; Foà, V

1989-01-01

Biotechnology has been defined as the application of biological organisms, systems or processes to manufacturing and service industries. In considering health aspects of biotechnological development it must be underlined that the use of microorganisms in traditional industries, such as the production of food, bread, beer and dairy products, has not added significantly to the more usual industrial hazards. The risk factors encountered in the biotechnology industry can be defined as general, i.e., common to other industrial activities, and specific, i.e., depending on the presence of microorganisms and/or their metabolic products. The specific health risks vary according to the type of process, but can be grouped into three main categories: immunological diseases, toxic effects; pathological effects of microorganisms. Allergic immunological diseases such as bronchial asthma, contact dermatitis, oculo-rhinitis and extrinsic allergic alveolitis are by far the most frequent and well known diseases occurring among workers employed on biotechnological production. Toxic effects were observed among workers employed on the production of antibiotics and hormones or single cell proteins, where absorption of endotoxins has been described. Infectious diseases may arise from uncontrolled dissemination of pathogenic microorganisms through aerosols, dusts, aqueous and semisolid sludge effluents from biotechnological plants. The greatest risks occur in the production of antiviral vaccines, in research laboratories and in waste-water treatment plants. Risk of pathogenic effects has also been speculated from exposure to engineered microorganisms in laboratory and environmental or agricultural applications. Safety precautions consisting of protective measures, and effective barriers of containment (both physical and biological) have to be advised according to the hazardous characteristics of the organisms.(ABSTRACT TRUNCATED AT 250 WORDS)

Biosafety Assessment of Microbial Strains Used in Biotechnology According to Their Taxonomy

Directory of Open Access Journals (Sweden)

Natalia I. Sheina

2017-03-01

Full Text Available A great variety of biotechnological products are now widely used in different ways in agriculture, medicine, food manufacturing and other areas of our life. Industrialized societies now more than ever depend on the use of genetically engineered products, with many of them synthesized using recombinant strains of microorganisms. There is an opinion that microbial strains used in biotechnology are potentially harmful for human health and the environment. Similar to many other countries, we have enacted environmental legislation in an effort to balance the risks and benefits of using biotechnological strains. Although environmental monitoring rules focus mainly on safety assessments of chemicals, the biosafety assessment of microbial strains used in biotechnology is a very important issue as well. This article summarizes 15 years of research on the biotechnological strains of microbes widely used as producers of various biological substances for industrial purposes, and their environmental and biotechnological applications. In our survey, we tried to evaluate possible adverse effects (general toxicity and damage to the immune system, potential sensitizing effects, and damage to normal microbiota caused by these microbes. It was shown that microscopical fungi of genera Aspergillus, Penicillium and Candida, and some gram-negative bacteria can affect the immune system and disrupt the normal balance of microbial flora of the intestinal tract in rats. The actinomycetes are less dangerous in that they cause fewer side effects. The investigation data obtained can be used to develop safety and hygienic standards for industrial microbes that will help decrease or minimize the occupational risk of infection or damage to the immune system when working with biotechnological strains of microbes.

[The role of biotechnology in pharmaceutical drug design].

Gaisser, Sibylle; Nusser, Michael

2010-01-01

Biotechnological methods have become an important tool in pharmaceutical drug research and development. Today approximately 15 % of drug revenues are derived from biopharmaceuticals. The most relevant indications are oncology, metabolic disorders and disorders of the musculoskeletal system. For the future it can be expected that the relevance of biopharmaceuticals will further increase. Currently, the share of substances in preclinical testing that rely on biotechnology is more than 25 % of all substances in preclinical testing. Products for the treatment of cancer, metabolic disorders and infectious diseases are most important. New therapeutic approaches such as RNA interference only play a minor role in current commercial drug research and development with 1.5 % of all biological preclinical substances. Investments in sustainable high technology such as biotechnology are of vital importance for a highly developed country like Germany because of its lack of raw materials. Biotechnology helps the pharmaceutical industry to develop new products, new processes, methods and services and to improve existing ones. Thus, international competitiveness can be strengthened, new jobs can be created and existing jobs preserved.

New crops are gradually establishing along with cultivation systems to reduce reliance on depleting fossil fuel reserves and sustain better adaptation to climate change. These biological assets could be efficiently exploited as bioenergy feedstocks. Bioenergy crops are versatile renewable sources with the potential to alternatively contribute on a daily basis towards the coverage of modern society's energy demands. Biotechnology may facilitate the breeding of elite energy crop genotypes, better suited for bio-processing and subsequent use that will improve efficiency, further reduce costs, and enhance the environmental benefits of biofuels. Innovative molecular techniques may improve a broad range of important features including biomass yield, product quality and resistance to biotic factors like pests or microbial diseases or environmental cues such as drought, salinity, freezing injury or heat shock. The current review intends to assess the capacity of biotechnological applications to develop a beneficial bioenergy pipeline extending from feedstock development to sustainable biofuel production and provide examples of the current state of the art on future energy crops.

Thailand faces a significant burden in terms of treating and managing degenerative and chronic diseases. Moreover, incidences of rare diseases are rising. Many of these-such as diabetes, cancer, and inherited inborn metabolic diseases-have no definite treatments or cure. Meanwhile, advanced health biotechnology has been found, in principle, to be an effective solution for these health problems. Qualitative approaches were employed to analyse the current situation and examine existing public policies related to advanced health biotechnologies in Thailand. The results of this analysis were then used to formulate policy recommendations. Our research revealed that the system in Thailand in relation to advanced health biotechnologies is fragmented, with multiple unaddressed gaps, underfunding of research and development (R&D), and a lack of incentives for the private sector. In addition, there are no clear definitions of advanced health biotechnologies, and coverage pathways are absent. Meanwhile, false advertising and misinformation are prevalent, with no responsible bodies to actively and effectively provide appropriate information and education (I&E). The establishment of a specialised institution to fill the gaps in this area is warranted. The development and implementation of a comprehensive national strategic plan related to advanced health biotechnologies, greater investment in R&D and I&E for all stakeholders, collaboration among agencies, harmonisation of reimbursement across public health schemes, and provision of targeted I&E are specifically recommended.

Juvenile Cerebral Palsy--is caused by damage of the motor control centers of the developing brain (cerebral refers to the cerebrum, which is the affected area of the brain, although the disorder probably involves connections between the cortex and other parts of the brain and palsy refers to disorder of movement). The clinical symptoms of juvenile cerebral palsy are very diversified and include gross and fine motor-coordination disorders, manual ability, locomotion, perception and response, speech, psychomotor retardation, emotional disorders. The primary therapeutic problem in children with cerebral palsy is learning to move in a lower position and learning to walk. The aim of this research is evaluation the action of the botulinum toxin on gait pattern of children with cerebral palsy. Application of a comprehensive BTS analysis of gait will get accurate, consistent EBM (Evidence Base Medicine) results. The children with pyramidal syndrome of juvenile cerebral palsy have been included in the examinations. The children have been divided into 2 random groups: group I--children treated with standard therapy a neurodevelopmental rehabilitation and classic kinesiotherapy, group II--hildren treated with standard therapy --eurodevelopmental rehabilitation, classic kinesiotherapy and a botulinum toxin. The children were examined three times: before the therapy, after 6 weeks of treatment and after 3 months of treatment. In the research BTS comprehensive motion analysis system have been used where influence of toxin botulin on walk stereotype of children was assessed. The treatment connected with standard rehabilitation and using botulinum toxin brings quicker walk improvement. Comparing the above treatment methods of influence on the walk stereotype of children with juvenile cerebral palsy, we can confirm, that standard treatment brings regular improvement, still, it requires longer period of time, often even 3 months. Using botulinum toxin brings quicker walk improvement

Biotechnology uses substances, materials or extracts derived from living cells, employing 22 million Europeans in a € 1.5 Tn endeavour, being the premier global economic growth opportunity this century. Significant advances have been made in red biotechnology using pharmaceutically and medically relevant applications, green biotechnology developing agricultural and environmental tools and white biotechnology serving industrial scale uses, frequently as process feedstocks. Red biotechnology has delivered dramatic improvements in controlling human disease, from antibiotics to overcome bacterial infections to anti-HIV/AIDS pharmaceuticals such as azidothymidine (AZT), anti-malarial compounds and novel vaccines saving millions of lives. Green biotechnology has dramatically increased food production through Agrobacterium and biolistic genetic modifications for the development of 'Golden Rice', pathogen resistant crops expressing crystal toxin genes, drought resistance and cold tolerance to extend growth range. The burgeoning area of white biotechnology has delivered bio-plastics, low temperature enzyme detergents and a host of feedstock materials for industrial processes such as modified starches, without which our everyday lives would be much more complex. Biotechnological applications can bridge these categories, by modifying energy crops properties, or analysing circulating nucleic acid elements, bringing benefits for all, through increased food production, supporting climate change adaptation and the low carbon economy, or novel diagnostics impacting on personalized medicine and genetic disease. Cross-cutting technologies such as PCR, novel sequencing tools, bioinformatics, transcriptomics and epigenetics are in the vanguard of biotechnological progress leading to an ever-increasing breadth of applications. Biotechnology will deliver solutions to unimagined problems, providing food security, health and well-being to mankind for centuries to come. Copyright © 2013

Synthetic Biology and the U.S. Biotechnology Regulatory System: Challenges and Options

Synthetic Biology and the U.S. Biotechnology Regulatory System: Challenges and Options Sarah R. Carter, Ph.D., J. Craig Venter Institute; Michael Rodemeyer, J.D., University of Virginia; Michele S. Garfinkel, Ph.D., EMBO; Robert M. Friedman, Ph.D., J. Craig Venter Institute In recent years, a range of genetic engineering techniques referred to as “synthetic biology” has significantly expanded the tool kit available to scientists and engineers, providing them with far greater capabilities to engineer organisms than previous techniques allowed. The field of synthetic biology includes the relatively new ability to synthesize long pieces of DNA from chemicals, as well as improved methods for genetic manipulation and design of genetic pathways to achieve more precise control of biological systems. These advances will help usher in a new generation of genetically engineered microbes, plants, and animals. The JCVI Policy Center team, along with researchers at the University of Virginia and EMBO, examined how well the current U.S. regulatory system for genetically engineered products will handle the near-term introduction of organisms engineered using synthetic biology. In particular, the focus was on those organisms intended to be used or grown directly in the environment, outside of a contained facility. The study concludes that the U.S. regulatory agencies have adequate legal authority to address most, but not all, potential environmental, health and safety concerns posed by these organisms. Such near-term products are likely to represent incremental changes rather than a marked departure from previous genetically engineered organisms. However, the study also identified two key challenges for the regulatory system, which are detailed in the report. First, USDA’s authority over genetically engineered plants depends on the use of an older engineering technique that is no longer necessary for many applications. The shift to synthetic biology and other newer genetic

Primordial germ cells (PGCs) generate new individuals through differentiation, maturation and fertilization. This means that the manipulation of PGCs is directly linked to the manipulation of individuals, making PGCs attractive target cells in the animal biotechnology field. A unique biological property of avian PGCs is that they circulate temporarily in the vasculature during early development, and this allows us to access and manipulate avian germ lines. Following the development of a technique for transplantation, PGCs have become central to avian biotechnology, in contrast to the use of embryo manipulation and subsequent transfer to foster mothers, as in mammalian biotechnology. Today, avian PGC transplantation combined with recent advanced manipulation techniques, including cell purification, cryopreservation, depletion, and long-term culture in vitro, have enabled the establishment of genetically modified poultry lines and ex-situ conservation of poultry genetic resources. This chapter introduces the principles, history, and procedures of producing avian germline chimeras by transplantation of PGCs, and the current status of avian germline modification as well as germplasm cryopreservation. Other fundamental avian reproductive technologies are described, including artificial insemination and embryo culture, and perspectives of industrial applications in agriculture and pharmacy are considered, including poultry productivity improvement, egg modification, disease resistance impairment and poultry gene "pharming" as well as gene banking.

Full Text Available Abstract Background Although the BTS-SIGN asthma guideline is one of the most well known and widely respected guidelines in the world, implementation in UK primary care remains patchy. Building on extensive earlier descriptive work, we sought to explore the way teamwork and inter-professional relationships impact on the implementation of the BTS-SIGN guideline on asthma in general practice. Methods Qualitative comparative case study using nine in-depth interviews and 2 focus groups with general practitioners and practice nurses, involved in delivering asthma care. Participants were purposively recruited from practices in a Scottish health board with high and low compliance with the BTS-SIGN asthma guideline. Results There was a marked difference in the way respondents from practices with high compliance and respondents from practices with low compliance spoke about the value of guidelines and the challenges of implementing them. On both accounts, the former were more positive than the latter and were able to be more specific about the strategies they used to overcome barriers to implementation. We explored the reason for this difference in response and identified practice organisation, centring on delegation of work to nurses, as a factor mediating the practice's level of compliance. Effective delegation was underpinned by organisation of asthma work among practice members who have the appropriate level of skills and knowledge, know and understand each others' work and responsibilities, communicate well among themselves and trust each others' skills. It was the combination of these factors which made for successful delegation and guideline implementation, not any one factor in isolation. Conclusion In our sample of practices, teamwork and organisation of care within practices appeared to impact on guideline implementation and further larger studies are needed to explore this issue further.

Re-Framing Biotechnology Regulation.

Science.gov (United States)

Peck, Alison

Biotechnology is about to spill the banks of federal regulation. New genetic engineering techniques like CRISPR-Cas9 promise revolutionary breakthroughs in medicine, agriculture, and public health—but those techniques would not be regulated under the terms of the Coordinated Framework for Regulation of Biotechnology. This revolutionary moment in biotechnology offers an opportunity to correct the flaws in the framework, which was hastily patched together at the advent of the technology. The framework has never captured all relevant technologies, has never satisfied the public that risk is being effectively managed, and has never been accessible to small companies and publicly-funded labs that increasingly are positioned to make radical, life-saving innovations. This Article offers a proposal for new legislation that would reshape biotechnology regulation to better meet these goals. Key reforms include tying regulation to risk rather than technology category; consolidating agency review; capturing distinct regulatory expertise through inter-agency consultations; creating a clearinghouse to help guide applicants and disseminate information; setting up more comprehensive monitoring of environmental effects; and providing federal leadership to fill key data gaps and address socio-economic impacts.

State responses to biotechnology.

Harris, Rebecca C

2015-01-01

This article reviews biotechnology legislation in the 50 states for 11 policy areas spanning 1990-2010, an era of immense growth in biotechnology, genetic knowledge, and significant policy development. Policies regarding health insurance, life insurance, long-term care insurance, DNA data bank collection, biotech research protection, biotech promotion and support, employment discrimination, genetic counselor licensing, human cloning, and genetic privacy each represent major policy responses arising from biotechnology and coinciding with key areas of state regulation (insurance, criminal justice, economic development, labor law, health and safety, privacy, and property rights). This analysis seeks to answer three questions regarding biotechnology legislation at the state level: who is acting (policy adoption), when is policy adopted (policy timing), and what is policy doing (policy content). Theoretical concerns examine state ideology (conservative or liberal), policy type (economic or moral), and the role of external events (federal law, news events, etc.) on state policy adoption. Findings suggest ideological patterns in adoption, timing, and content of biotech policy. Findings also suggest economic policies tend to be more uniform in content than moral policies, and findings also document a clear link between federal policy development, external events, and state policy response.

As we enter the 21st century, the sustainability of the biosphere is a global challenge that can best be met with a global response. This includes how we train and promote our next generation of research scientists in the emerging arenas of genome-enabled biology and a bio-based economy. It is this fundamental issue that formed the motivation for designing and conducting a shortcourse entitled “FACILIS 2014: Microbially-driven facilitation systems in environmental biotechnology” (hereafter “FACILIS”) presented here by the European Commission (EC)-United States (US) Task Force on Biotechnology Research. This WG was established in 1994 under the umbrella of the US-EC Task Force on Biotechnology Research, a transatlantic collaborative group overseen by the US Office of Science and Technology Policy (OSTP) and the EC. The Environmental Biotechnology Working Group maintains several goals, including establishing research links between scientists in EU countries and the US and fostering the careers of junior scientists from both sides of the Atlantic to the global nature of scientific cooperation. To that end, a shortcourse was held at the University of Milan in Italy on July 12-25 2014 organized around cross-cutting themes of genomic science and designed to attract a stellar group of interdisciplinary early carrier researchers. A total of 22 students, 10 from the US and 12 from the EU participated. The course provided them with hands-on experience with the latest scientific methods in genomics and bioinformatics; using a format that combines lectures, laboratory research and field work with the final goal to enable researchers to finally turn data into knowledge.

Knowledge and Attitudes Towards Biotechnology of Elementary Education Preservice Teachers: The first Spanish experience

Science.gov (United States)

Casanoves, Marina; González, Ángel; Salvadó, Zoel; Haro, Juan; Novo, Maite

2015-11-01

Due to the important impact that biotechnology has on current Western societies, well-informed critical citizens are needed. People prepared to make conscious decisions about aspects of biotechnology that relate to their own lives. Teachers play a central role in all education systems. Thus, the biotechnological literacy of preservice teachers is an important consideration as they will become an influential collective as future teachers of the next generation of children. The attitudes toward science (and biotechnology) that teachers have affect their behavior and influence the way they implement their daily practice of science teaching in school. This study analyzes the attitudes and knowledge of Spanish preservice teachers toward biotechnology. We designed a new survey instrument that was completed by 407 university students who were taking official degree programs in preschool and primary education. Our results point out that although they are aware of biotechnology applications, topics concerning the structure of DNA, management of genetic information inside the cell, genetically modified organism technology and the use of microorganisms as biotechnological tools were not correctly answered. According to our attitude analysis, Spanish preservice teachers could be defined as opponents of genetically modified product acquisition, supporters of biotechnology for medical purposes and highly interested in increasing their knowledge about biotechnology and other scientific advances. Our results show a positive correlation between better knowledge and more positive attitudes toward biotechnology. A Spanish preservice teacher with positive attitudes toward biotechnology tends to be a student with a strong biology background who scored good marks in our knowledge test.

Full Text Available Background and Objectives: New Hazards interface the environment and human life along with technology development. One of these pollutants is electromagnetic field and it’s known and unknown bad effects on the environment, this study determines the vertical publishing (height measurement of microwave antennas in the city of Hashtgerd. Methods: The basic information including the geographical location of the BTS antennas in the city, brand, the operator type, installation and its height was received from CRA and radio communications, and then the measuring was done by using the standard method of IEEE STD 95. 1 by the SPECTRAN 4060, and by using crane elevator in 17-meters height near the BTS antennas (15 meters.analysis were done by Spss16 and by Kolmogorov Smirnov test, multiple regression method. Results: Results show that in the both operators of Irancell and Hamrah-e-aval, density will increase by increasing measurement height or decreasing the vertical distance of broadcaster antenna. Regarding to the mix model test, a meaningful statistical relationship can be seen between measurement height and the density average in both types of the operators. Conclusion: while measuring height increased or in other words got closer to the antennas, density average increased in both operators, so the highest number was reported in the minimum vertical distance compared to the Irancell operator antenna was 25 mw/m2 and the lowest number was related to Hamrah-e-aval operator in the maximum vertical distance which was 0.02mw/m2. Thus, people stationed in the tall buildings parallel with installation height of antennas or in less vertical distance of them, are more exposed to the waves.

2015-01-01

L-DOPA (3,4-dihydroxyphenyl-L-alanine) has been widely used as a drug for Parkinson's disease caused by deficiency of the neurotransmitter dopamine. Since Monsanto developed the commercial process for L-DOPA synthesis for the first time, most of currently supplied L-DOPA has been produced by the asymmetric method, especially asymmetric hydrogenation. However, the asymmetric synthesis shows critical limitations such as a poor conversion rate and a low enantioselectivity. Accordingly, alternative biotechnological approaches have been researched for overcoming the shortcomings: microbial fermentation using microorganisms with tyrosinase, tyrosine phenol-lyase, or p-hydroxyphenylacetate 3-hydroxylase activity and enzymatic conversion by immobilized tyrosinase. Actually, Ajinomoto Co. Ltd commercialized Erwinia herbicola fermentation to produce L-DOPA from catechol. In addition, the electroenzymatic conversion system was recently introduced as a newly emerging scheme. In this review, we aim to not only overview the biotechnological L-DOPA production methods, but also to briefly compare and analyze their advantages and drawbacks. Furthermore, we suggest the future potential of biotechnological L-DOPA production as an industrial process.

Termites as targets and models for biotechnology.

Science.gov (United States)

Scharf, Michael E

2015-01-07

Termites have many unique evolutionary adaptations associated with their eusocial lifestyles. Recent omics research has created a wealth of new information in numerous areas of termite biology (e.g., caste polyphenism, lignocellulose digestion, and microbial symbiosis) with wide-ranging applications in diverse biotechnological niches. Termite biotechnology falls into two categories: (a) termite-targeted biotechnology for pest management purposes, and (b) termite-modeled biotechnology for use in various industrial applications. The first category includes several candidate termiticidal modes of action such as RNA interference, digestive inhibition, pathogen enhancement, antimicrobials, endocrine disruption, and primer pheromone mimicry. In the second category, termite digestomes are deep resources for host and symbiont lignocellulases and other enzymes with applications in a variety of biomass, industrial, and processing applications. Moving forward, one of the most important approaches for accelerating advances in both termite-targeted and termite-modeled biotechnology will be to consider host and symbiont together as a single functional unit.

Aboard the International Space Station (ISS), the Tissue Culture Module (TCM) is the stationary bioreactor vessel in which cell cultures grow. However, for the Cellular Biotechnology Operations Support Systems-Fluid Dynamics Investigation (CBOSS-FDI), color polystyrene beads are used to measure the effectiveness of various mixing procedures. Uniform mixing is a crucial component of CBOSS experiments involving the immune response of human lymphoid cell suspensions. In this picture, the beads are trapped in the injection port shortly after injection. Swirls of beads indicate, event to the naked eye, the contents of the TCM are not fully mixed. The beads are similar in size and density to human lymphoid cells. The goal is to develop procedures that are both convenient for the flight crew and are optimal in providing uniform and reproducible mixing of all components, including cells. The average bead density in a well mixed TCM will be uniform, with no bubbles, and it will be measured using the absorption of light

Microalgae constitute a diverse group of eukaryotic unicellular organisms that are of interest for pure and applied research. Owing to their natural synthesis of value-added natural products microalgae are emerging as a source of sustainable chemical compounds, proteins and metabolites, including but not limited to those that could replace compounds currently made from fossil fuels. For the model microalga, Chlamydomonas reinhardtii, this has prompted a period of rapid development so that this organism is poised for exploitation as an industrial biotechnology platform. The question now is how best to achieve this? Highly advanced industrial biotechnology systems using bacteria and yeasts were established in a classical metabolic engineering manner over several decades. However, the advent of advanced molecular tools and the rise of synthetic biology provide an opportunity to expedite the development of C. reinhardtii as an industrial biotechnology platform, avoiding the process of incremental improvement. In this review we describe the current status of genetic manipulation of C. reinhardtii for metabolic engineering. We then introduce several concepts that underpin synthetic biology, and show how generic parts are identified and used in a standard manner to achieve predictable outputs. Based on this we suggest that the development of C. reinhardtii as an industrial biotechnology platform can be achieved more efficiently through adoption of a synthetic biology approach. © 2015 The Authors The Plant Journal published by Society for Experimental Biology and John Wiley & Sons Ltd.

In the last decades several new biotechnologically-based therapeutics have been developed due to progress in genetic engineering. A growing challenge facing pharmaceutical scientists is formulating these compounds into oral dosage forms with adequate bioavailability. An increasingly popular approach to formulate biotechnology-based therapeutics is the use of lipid based formulation technologies. This review highlights the importance of lipid based drug delivery systems in the formulation of oral biotechnology based therapeutics including peptides, proteins, DNA, siRNA and vaccines. The different production procedures used to achieve high encapsulation efficiencies of the bioactives are discussed, as well as the factors influencing the choice of excipient. Lipid based colloidal drug delivery systems including liposomes and solid lipid nanoparticles are reviewed with a focus on recent advances and updates. We further describe microemulsions and self-emulsifying drug delivery systems and recent findings on bioactive delivery. We conclude the review with a few examples on novel lipid based formulation technologies.

2004-02-01

The incidence of mesothelioma is rising rapidly in the UK. There is no generally accepted standard treatment. The BTS recommends active symptom control (ASC). It is not known whether chemotherapy in addition prolongs survival or provides worthwhile palliation with acceptable toxicity. Palliation as recorded by patients has been fully reported for only two regimens: mitomycin, vinblastine, and cisplatin (MVP), and vinorelbine (N). The BTS and collaborators planned to conduct a phase III randomised trial comparing ASC only, ASC+MVP, and ASC+N in 840 patients with survival as the primary outcome measure. The aim of the present study was to assess the acceptability of the trial design to patients and the suitability of two standard quality of life (QL) questionnaires for mesothelioma. Collaborating centres registered all new patients with mesothelioma. Those eligible and giving informed consent completed EORTC QLQ-C30+LC13 and FACT-L QL questionnaires and were randomised between all three or any two of (1) ASC only, (2) ASC+4 cycles of MVP, and (3) ASC+12 weekly doses of N. During 1 year, 242 patients were registered of whom 109 (45%) were randomised (55% of the 197 eligible patients). Fifty two patients from 20 centres were randomised to an option including ASC only. This translates into a rate of 312 per year from 60 centres interested in collaborating in the phase III trial. The EORTC QL questionnaire was superior to FACT-L in terms of completeness of data and patient preference. Clinically relevant palliation was achieved with ASC. The planned phase III trial is feasible.

Biotechnology and Consumer Decision-Making.

Science.gov (United States)

Sax, Joanna K

Society is facing major challenges in climate change, health care and overall quality of life. Scientific advances to address these areas continue to grow, with overwhelming evidence that the application of highly tested forms of biotechnology is safe and effective. Despite scientific consensus in these areas, consumers appear reluctant to support their use. Research that helps to understand consumer decision-making and the public’s resistance to biotechnologies such as vaccines, fluoridated water programs and genetically engineered food, will provide great social value. This article is forward-thinking in that it suggests that important research in behavioral decision-making, specifically affect and ambiguity, can be used to help consumers make informed choices about major applications of biotechnology. This article highlights some of the most controversial examples: vaccinations, genetically engineered food, rbST treated dairy cows, fluoridated water, and embryonic stem cell research. In many of these areas, consumers perceive the risks as high, but the experts calculate the risks as low. Four major thematic approaches are proposed to create a roadmap for policymakers to consider for policy design and implementation in controversial areas of biotechnology. This article articulates future directions for studies that implement decision-making research to allow consumers to appropriately assign risk to their options and make informed decisions.

2005-12-01

Biotechnology-derived food crops are currently being developed in Malaysia mainly for disease resistance and improved post harvest quality. The modern biotechnology approach is adopted because of its potential to overcome constraints faced by conventional breeding techniques. Research on the development of biotechnology-derived papaya, pineapple, chili, passion fruit, and citrus is currently under way. Biotechnology-derived papaya developed for resistance to papaya ringspot virus (PRSV) and improved postharvest qualities is at the field evaluation stage. Pineapple developed for resistance to fruit black heart disorder is also being evaluated for proof-of-concept. Other biotechnology-derived food crops are at early stages of gene cloning and transformation. Activities and products involving biotechnology-derived crops will be fully regulated in the near future under the Malaysian Biosafety Law. At present they are governed only by guidelines formulated by the Genetic Modification Advisory Committee (GMAC), Malaysia. Commercialization of biotechnology-derived crops involves steps that require GMAC approval for all field evaluations and food-safety assessments before the products are placed on the market. Public acceptance of the biotechnology product is another important factor for successful commercialization. Understanding of biotechnology is generally low among Malaysians, which may lead to low acceptance of biotechnology-derived products. Initiatives are being taken by local organizations to improve public awareness and acceptance of biotechnology. Future research on plant biotechnology will focus on the development of nutritionally enhanced biotechnology-derived food crops that can provide more benefits to consumers.

Biotechnology's foreign policy.

Science.gov (United States)

Feldbaum, Carl

2002-01-01

From its inception, biotechnology has been a uniquely international enterprise. An American and an Englishman working together elucidated the structure of DNA almost 50 years ago; more recently, the Human Genome Project linked researchers around the world, from the Baylor College of Medicine in Houston to the Beijing Human Genome Center. Today our industry's researchers hail from African villages and Manhattan high rises; from Munich and Melbourne; from London, Ontario, and London, England; from Scotland and Nova Scotia--New Scotland; from Calcutta and Calgary. But in the beginning, the infrastructure that supported these efforts--intellectual property, venture capital, streamlined technology transfer--was less widely dispersed and the world's brightest biotech researchers clustered in only half a dozen scientific Meccas. Previous technological revolutions have spread around the world. Following in their footsteps, biotechnology's global diaspora seems inevitable, especially since governments are promoting it. But as our science and business emigrate from early strongholds in the United States, Canada and Europe across oceans and borders and into new cultures, international tensions over biotechnology continue to grow. In just the last few years, controversies have rolled over R&D spending priorities, genetic patents, bioprospecting, transgenic agriculture and drug pricing. My premise today is that our industry needs to formulate its first foreign policy, one which is cognizant of the miserable judgments and mistakes of other industries--and avoids them.

An updated view on horseradish peroxidases: recombinant production and biotechnological applications.

Science.gov (United States)

Krainer, Florian W; Glieder, Anton

2015-02-01

Horseradish peroxidase has been the subject of scientific research for centuries. It has been used exhaustively as reporter enzyme in diagnostics and histochemistry and still plays a major role in these applications. Numerous studies have been conducted on the role of horseradish peroxidase in the plant and its catalytic mechanism. However, little progress has been made in its recombinant production. Until now, commercial preparations of horseradish peroxidase are still isolated from plant roots. These preparations are commonly mixtures of various isoenzymes of which only a small fraction has been described so far. The composition of isoenzymes in these mixed isolates is subjected to uncontrollable environmental conditions. Nowadays, horseradish peroxidase regains interest due to its broad applicability in the fields of medicine, life sciences, and biotechnology in cancer therapy, biosensor systems, bioremediation, and biocatalysis. These medically and commercially relevant applications, the recent discovery of new natural isoenzymes with different biochemical properties, as well as the challenges in recombinant production render this enzyme particularly interesting for future biotechnological solutions. Therefore, we reviewed previous studies as well as current developments with biotechnological emphasis on new applications and the major remaining biotechnological challenge-the efficient recombinant production of horseradish peroxidase enzymes.

A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Transplantation Society (BTS) has reviewed the available literature and made recommendations for the diagnosis and management of post-transplant lymphoproliferative disorder (PTLD) in adult recipients of solid organ transplants. This review details the risk factors predisposing to development, initial features and diagnosis. It is important that the risk of developing PTLD is considered when using post transplant immunosuppression and that the appropriate investigations are carried out when there are suspicions of the diagnosis. These must include tissue for histology and computed tomography scan to assess the extent of disease. These recommendations have been made primarily for adult patients, there have been some comments made with regard to paediatric practice.

The results of collaborative work carried out in the field of biotechnology at the Frank Laboratory of Neutron Physics (FLNP) of the Joint Institute for Nuclear Research (JINR) (Dubna, Russia) jointly with scientists from Georgia are presented. Using instrumental neutron activation analysis (NAA), significant results were ontained in the following directions - medical biotechnology, environmental biotechnology and industrial biotechnology. In the biomedical experiments a blue-green alga Spirulina platensis biomass has been used as a matrix for the development of pharmaceutical substances containing such vitally important trace elements as selenium, chromium and iodine. The feasibility of target-oriented introduction of these elements into Spirulina platensis biocomplexes retaining its protain composition and natural beneficial properties has been proved. The adsorption of such toxic metal as mercury by Spirulina platensis biomass in dynamics of growth has been studied also. NAA has been successfully applied to investigate the biotechnology of toxic Cr(VI) transformation into less toxic Cr(III) complexes by Cr(VI)-reducer bacteria isolated from polluted basalts in Georgia. This method was used to track accumulation of chromium in the bacterial cells. To monitor and identify Cr(III) complexes in these bacteria, electron spin resonance (ESR) spectrometry was employed. For the first time, the elemental composition of Cr(VI)-reducer bacteria has been studied using epithermal NAA. The natural organic mass of vegetal origin - peat - was applied as a source of microorganisms to study the bacterial leaching of some metals from lean ores, rocks and industrial wastes. (author)

Ligon, R Allen; Ooi, Yinn K; Kim, Dennis W; Vincent, Robert N; Petit, Christopher J

2017-09-11

The purpose of this study was to compare results between the femoral arterial (FA) and carotid arterial (CA) approaches in catheter-based interventions on Blalock-Taussig shunts (BTS). Transcatheter intervention on BTS is often performed in shunt-dependent, hypoxemic infants. The approach to BTS intervention likely has an impact on timeliness and overall success. The authors reviewed all cases of catheter intervention for BTS obstruction between 2012 and 2017 for their institution. They sought to compare procedural success rates and time, sheath time, time to arterial access, and time from access to stent implantation between FA and CA approaches. There were 42 BTS interventions between 34 patients. BTS intervention was more successful from the CA approach (p = 0.035). Among the FA cohort, BTS intervention was unsuccessful in 8 cases (25%), 5 of which were converted to CA with subsequent success. The CA cohort had lower procedure time (62 min vs. 104 min; p = 0.01) and anesthesia time (119 min vs. 151 min; p = 0.01). Additionally, CA access was associated with shorter time to arterial access (4.0 min vs. 9.3 min; p BTS (6.5 min vs. 13 min; p BTS stent implantation (9 min vs. 20 min; p BTS deliberately. The authors' approach has been the carotid artery as an alternative access site-associated with greater procedural success, shorter procedural time, and shorter time to stent implantation.

Perspectives on biotechnological applications of archaea

Science.gov (United States)

Schiraldi, Chiara; Giuliano, Mariateresa; De Rosa, Mario

2002-01-01

Many archaea colonize extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties, they are a potentially valuable resource in the development of novel biotechnological processes. Despite extensive research, however, there are few existing industrial applications of either archaeal biomass or archaeal enzymes. This review summarizes current knowledge about the biotechnological uses of archaea and archaeal enzymes with special attention to potential applications that are the subject of current experimental evaluation. Topics covered include cultivation methods, recent achievements in genomics, which are of key importance for the development of new biotechnological tools, and the application of wild-type biomasses, engineered microorganisms, enzymes and specific metabolites in particular bioprocesses of industrial interest.

A bibliometric assessment of ASEAN collaboration in plant biotechnology

KAUST Repository

Payumo, Jane

2015-04-03

This study draws on publication and citation data related to plant biotechnology from a 10-year (2004–2013) period to assess the research performance, impact, and collaboration of member states of the Association of Southeast Asian Nations (ASEAN). Plant biotechnology is one of the main areas of cooperation between ASEAN member states and among the research areas promoted to achieve regional food security and sustainable development. In general, findings indicate increased scientific output, influence, and overall collaboration of ASEAN countries in plant biotechnology over time. Research performance and collaboration (domestic, regional, and international) of the region in plant biotechnology are linked to the status of the economic development of each member country. Thailand produced the most publications of the ASEAN member states while Singapore had the highest influence as indicated by its citation activity in plant biotechnology among the ASEAN countries. Domestic and international collaborations on plant biotechnology are numerous. Regional collaboration or partnership among ASEAN countries was, however, was found to be very limited, which is a concern for the region’s goal of economic integration and science and technology cooperation. More studies using bibliometric data analysis need to be conducted to understand plant biotechnology cooperation and knowledge flows between ASEAN countries. © 2015 Akadémiai Kiadó, Budapest, Hungary

Full Text Available A sharp decline in the availability of arable land and sufficient supply of irrigation water along with a continuous steep increase in food demands have exerted a pressure on farmers to produce more with fewer resources. A viable solution to release this pressure is to speed up the plant breeding process by employing biotechnology in breeding programs. The majority of biotechnological applications rely on information generated from various -omic technologies. The latest outstanding improvements in proteomic platforms and many other but related advances in plant biotechnology techniques offer various new ways to encourage the usage of these technologies by plant scientists for crop improvement programs. A combinatorial approach of accelerated gene discovery through genomics, proteomics, and other associated -omic branches of biotechnology, as an applied approach, is proving to be an effective way to speed up the crop improvement programs worldwide. In the near future, swift improvements in -omic databases are becoming critical and demand immediate attention for the effective utilization of these techniques to produce next-generation crops for the progressive farmers. Here, we have reviewed the recent advances in proteomics, as tools of biotechnology, which are offering great promise and leading the path towards crop improvement for sustainable agriculture.

Industrial use of Biotechnology in Agriculture

International Nuclear Information System (INIS)

But, S.J.

2006-01-01

In the past the biological research was restricted within the boundary of laboratories and the subsequent results were often employed merely to strengthen the research knowledge and information. In life sciences, the traditional methods took years in proving the biological facts. At the leg of last century, the practical application of biotechnology provided a powerful tool to mankind that has led to a revolutionary change in modern agriculture. In the present era, the economy of agro-based countries all over the world is dependent on the adaptation of the pattern of crop-production and their improvement through modern biotechnological means. Biotechnology is in fact the name of a combination of techniques involved to make the full use of living organisms, either in total or in part, for the benefit of plants, animals or human beings. Progressive and dynamic investors, associated with researches/scientists, should be encouraged to step forward for the mobilization of emerging trend of biotechnological industry in agriculture. Researcher/Scientists of biological programmes in Pakistan should be encouraged at Government level to come forward in contributing their tremendous role to boost Agr- industry in the country.

Biotechnology of non-Saccharomyces yeasts-the basidiomycetes.

Science.gov (United States)

Johnson, Eric A

2013-09-01

Yeasts are the major producer of biotechnology products worldwide, exceeding production in capacity and economic revenues of other groups of industrial microorganisms. Yeasts have wide-ranging fundamental and industrial importance in scientific, food, medical, and agricultural disciplines (Fig. 1). Saccharomyces is the most important genus of yeast from fundamental and applied perspectives and has been expansively studied. Non-Saccharomyces yeasts (non-conventional yeasts) including members of the Ascomycetes and Basidiomycetes also have substantial current utility and potential applicability in biotechnology. In an earlier mini-review, "Biotechnology of non-Saccharomyces yeasts-the ascomycetes" (Johnson Appl Microb Biotechnol 97: 503-517, 2013), the extensive biotechnological utility and potential of ascomycetous yeasts are described. Ascomycetous yeasts are particularly important in food and ethanol formation, production of single-cell protein, feeds and fodder, heterologous production of proteins and enzymes, and as model and fundamental organisms for the delineation of genes and their function in mammalian and human metabolism and disease processes. In contrast, the roles of basidiomycetous yeasts in biotechnology have mainly been evaluated only in the past few decades and compared to the ascomycetous yeasts and currently have limited industrial utility. From a biotechnology perspective, the basidiomycetous yeasts are known mainly for the production of enzymes used in pharmaceutical and chemical synthesis, for production of certain classes of primary and secondary metabolites such as terpenoids and carotenoids, for aerobic catabolism of complex carbon sources, and for bioremediation of environmental pollutants and xenotoxicants. Notwithstanding, the basidiomycetous yeasts appear to have considerable potential in biotechnology owing to their catabolic utilities, formation of enzymes acting on recalcitrant substrates, and through the production of unique primary

Laimer, Margit; Mendonça, Duarte; Maghuly, Fatemeh; Marzban, Gorji; Leopold, Stephan; Khan, Mahmood; Balla, Ildiko; Katinger, Hermann

2005-01-01

Challenges concerning fruit trees and grapevines as long lived woody perennial crops require adapted biotechnological approaches, if solutions are to be found within a reasonable time frame. These challenges are represented by the need for correct identification of genetic resources, with the foreseen use either in conservation or in breeding programmes. Molecular markers provide most accurate information and will be the major solution for questions about plant breeders rights. Providing healthy planting material and rapid detection of newly introduced pathogens by reliable methods involving serological and molecular biological tools will be a future challenge of increases importance, given the fact that plant material travels freely in the entire European Union. But also new breeding goals and transgenic solutions are part of the biotechnological benefits, e.g. resistance against biotic and abiotic stress factors, modified growth habits, modified nutritional properties and altered processing and storage qualities. The successful characterization of transgenic grapevines and stone fruit trees carrying genes of viral origin in different vectors constructed under ecological consideration, will be presented. Beyond technical feasibility, efficiency of resistance, environmental safety and Intellectual Property Rights, also public acceptance needs consideration and has been addressed in a specific project. The molecular determination of internal quality parameters of food can also be addressed by the use of biotechnological tools. Patient independent detection tools for apple allergens have been developed and should allow to compare fruits from different production systems, sites, and genotypes for their content of health threatening compounds.

Electron shuttles in biotechnology.

Science.gov (United States)

Watanabe, Kazuya; Manefield, Mike; Lee, Matthew; Kouzuma, Atsushi

2009-12-01

Electron-shuttling compounds (electron shuttles [ESs], or redox mediators) are essential components in intracellular electron transfer, while microbes also utilize self-produced and naturally present ESs for extracellular electron transfer. These compounds assist in microbial energy metabolism by facilitating electron transfer between microbes, from electron-donating substances to microbes, and/or from microbes to electron-accepting substances. Artificially supplemented ESs can create new routes of electron flow in the microbial energy metabolism, thereby opening up new possibilities for the application of microbes to biotechnology processes. Typical examples of such processes include halogenated-organics bioremediation, azo-dye decolorization, and microbial fuel cells. Herein we suggest that ESs can be applied widely to create new microbial biotechnology processes.

Oil and biotechnology

Energy Technology Data Exchange (ETDEWEB)

Yasui, Yoshiaki

1988-06-01

The secondary oil recovery due to microorganisms and the production of useful substances from oil distillates using microorganisms are described as examples to solidify the relationship between oil and biotechnology. The secondary crude-oil recovery has been carried out due to the microorganism drive process, which includes the on-the-ground and underground processes. Although the microorganism drive process has been investigated for many years, the selection of the microorganisms is not completely established. Many uncertainties still remain regarding the technical and economic aspects. The single cell protein (SCP) is an example of industrial success in the production of useful substances from the oil. Rumania has produced SCP from normal paraffin and the U. K. from the methanol and the products are used as the protein source for animals. Remarkable progress in the functional efficiency of microorganisms is expected due to the biotechnology for both applications. (4 tabs)

Angenon, Geert; Van Lijsebettens, Mieke; Van Montagu, Marc

2013-01-01

This dialogue was held between the Guest Editors of the Special Issue on "Plant Transgenesis" of the Int. J. Dev. Biol. and Marc Van Montagu. Research in the group of Marc Van Montagu and Jeff Schell in the 1970s was essential to reveal how the phytopathogenic bacterium Agrobacterium tumefaciens transfers DNA to host plants to cause crown gall disease. Knowledge of the molecular mechanism underlying gene transfer, subsequently led to the development of plant transgene technology, an indispensable tool in fundamental plant research and plant improvement. In the early 1980s, Marc Van Montagu founded a start-up company, Plant Genetic Systems, which successfully developed insect-resistant plants, herbicide-tolerant plants and a hybrid seed production system based on nuclear male sterility. Even before the first transgenic plant had been produced, Marc Van Montagu realized that the less developed countries might benefit most from plant biotechnology and throughout his subsequent career, this remained a focus of his efforts. After becoming emeritus professor, he founded the Institute of Plant Biotechnology Outreach (IPBO), which aims to raise awareness of the major role that plant biotechnology can play in sustainable agricultural systems, especially in less developed countries. Marc Van Montagu has been honored with many prizes and awards, the most recent being the prestigious World Food Prize 2013. In this paper, we look to the past and present of plant biotechnology and to the promises this technology holds for the future, on the basis of the personal perspective of Marc Van Montagu.

2007-12-01

Full Text Available Abstract Background The benefits of genomics and biotechnology are concentrated primarily in the industrialized world, while their potential to combat neglected diseases in the developing world has been largely untapped. Without building developing world biotechnology capacity to address local health needs, this disparity will only intensify. To assess the potential of genomics to address health needs in the developing world, the McLaughlin-Rotman Centre for Global Health, along with local partners, organized five courses on Genomics and Public Health Policy in the developing world. The overall objective of the courses was to collectively explore how to best harness genomics to improve health in each region. This article presents and analyzes the recommendations from all five courses. Discussion In this paper we analyze recommendations from 232 developing world experts from 58 countries who sought to answer how best to harness biotechnology to improve health in their regions. We divide their recommendations into four categories: science; finance; ethics, society and culture; and politics. Summary The Courses' recommendations can be summarized across the four categories listed above: Science - Collaborate through national, regional, and international networks - Survey and build capacity based on proven models through education, training, and needs assessments Finance - Develop regulatory and intellectual property frameworks for commercialization of biotechnology - Enhance funding and affordability of biotechnology - Improve the academic-industry interface and the role of small and medium enterprise Ethics, Society, Culture - Develop public engagement strategies to inform and educate the public about developments in genomics and biotechnology - Develop capacity to address ethical, social and cultural issues - Improve accessibility and equity Politics - Strengthen understanding, leadership and support at the political level for biotechnology

Gartland, Kevan M A; Gartland, Jill S

2018-06-08

Strategies for biotechnology must take account of opportunities for research, innovation and business growth. At a regional level, public-private collaborations provide potential for such growth and the creation of centres of excellence. By considering recent progress in areas such as genomics, healthcare diagnostics, synthetic biology, gene editing and bio-digital technologies, opportunities for smart, strategic and specialised investment are discussed. These opportunities often involve convergent or disruptive technologies, combining for example elements of pharma-science, molecular biology, bioinformatics and novel device development to enhance biotechnology and the life sciences. Analytical applications use novel devices in mobile health, predictive diagnostics and stratified medicine. Synthetic biology provides opportunities for new product development and increased efficiency for existing processes. Successful centres of excellence should promote public-private business partnerships, clustering and global collaborations based on excellence, smart strategies and innovation if they are to remain sustainable in the longer term.

Ethical limitations in patenting biotechnological inventions.

Science.gov (United States)

Lugagnani, V

1999-01-01

In order to connect ethical considerations with practical limits to patentability, the moral judgement should possibly move from the exploitation of the invention to the nature and/or objectives of Research and Development (R&D) projects which have produced it: in other words, it appears quite reasonable and logical that Society is not rewarding unethical R&D activities by granting intellectual property rights. As far as biotechnology R&D is concerned, ethical guidance can be derived from the 1996 Council of EuropeOs OConvention for the protection of human rights and dignity of the human being with regard to the application of biology and medicineO, whose Chapter V - Scientific research - provides guidelines on: i. protection of persons undergoing research (e.g. informed consent); ii. protection of persons not able to consent to research; iii. research on embryos in vitro. As far as the specific point of patenting biotechnology inventions is concerned, the four exclusions prescribed by Directive 98/44/EC (i.e. human cloning, human germ-line gene therapy, use of human embryos for commercial purposes, unjustified animal suffering for medical purposes) are all we have in Europe in terms of ethical guidance to patentability. In Italy, in particular, we certainly need far more comprehensive legislation, expressing SocietyOs demand to provide ethical control of modern biotechnology. However it is quite difficult to claim that ethical concerns are being raised by currently awarded biotechnology patents related to living organisms and material thereof; they largely deal with the results of genomic R&D, purposely and usefully oriented toward improving health-care and agri-food processes, products and services. ONo patents on lifeOO can be an appealing slogan of militants against modern biotechnology, but it is far too much of an over-simplified abstraction to become the Eleventh Commandment our Society.

During the last half century, biotechnology has contributed to the development of many important new and useful products that have improved our quality of life. To a large extent, these contributions are attributable to advances in cellular and molecular biology that can be traced to the discovery of DNA. What began as a science involved with manipulations of whole organisms has transcended into an ability to influence organisms at the cellular and molecular levels with greater speed, flexibility and precision than ever before. This has produced significantly improved pharmaceutical, textile, diagnostic, and environmental products, to name just a few. Early in this new century, biotechnology research is expected to literally explode with exciting new and promising opportunities. More importantly, biotechnology research in the low gravity environment of space is expected to play a significant part in this biotechnology revolution by expediting the discovery of important new medical, agricultural and environmental products. .

Tissue-engineered constructs made of biotechnology-derived materials have been preferred due to their chemical and physical composition, which offers both high versatility and a support to enclose/ incorporate relevant signaling molecules and/or genes known to therapeutically induce tissue repair. Herein, a critical overview of the impact of different biotechnology-derived materials, scaffolds, and recombinant signaling molecules over the behavior of cells, another element of tissue engineered constructs, as well its regulatory role in tissue regeneration and disease progression is given. Additionally, these tissue-engineered constructs evolved to three-dimensional (3D) tissue-like models that, as an advancement of two-dimensional standard culture methods, are expected to be a valuable tool in the field of drug discovery and pharmaceutical research. Despite the improved design and conception of current proposed 3D tissue-like models, advanced control systems to enable and accelerate streamlining and automation of the numerous labor-intensive steps intrinsic to the development of tissue-engineered constructs are still to be achieved. In this sense, this review intends to present the biotechnology- derived materials that are being explored in the field of tissue engineering to generate 3D tissue-analogues and briefly highlight their foremost breakthroughs in tissue regeneration and drug discovery. It also aims to reinforce that the crosstalk between tissue engineering and pharmaceutical biotechnology has been fostering the outcomes of tissue engineering approaches through the use of biotechnology-derived signaling molecules. Gene delivery/therapy is also discussed as a forefront area that represents another cross point between tissue engineering and pharmaceutical biotechnology, in which nucleic acids can be considered a "super pharmaceutical" to drive biological responses, including tissue regeneration.

The biology of planktotrophic larvae of Concholepas concholepas is the main bottleneck towards developing biotechnologies to rear this muricid. Data concerning planktonic larvae development, diets and environmental signals triggering larval settlement and recruitment is scarce. We have begun the study of the molecular and cell biology of embryos, larvae and recruits having as a final goal, the development of appropriate biotechnologies to rear this gastropod. First, an inverse ratio between BuChE and AChE enzyme activities was established. This ratio may be a precise developmental marker for this species. Second, for the first time a phosphoinositide related regulatory pathway is reported in a muricid, opening a new approach to the biotechnological management of larvae. Third, the relation between sulfate in sea water and larval motility was studied. Concentrations below 125 microM sulfate decreases larval motility. The sulfate is incorporated in proteoglycans which participate in different developmental phenomena. Lastly, a genomic Concholepas concholepas DNA sequence, similar to that of a human growth hormone probe was detected. This is very interesting since growth factors are key molecules during development, growth and are involved in food conversion rates in fish and also, in a variety of marine invertebrates.

Dendrimers, commonly referred to as polymeric trees, offer endless opportunities for biotechnological and biomedical applications. By controlling the type, length, and molecular weight of the core, branches and end groups, respectively, the chemical functionality and topology of dendrimeric archetypes can be customized which further can be applied to achieve required solubility, biodegradability, diagnosis and other applications. Given the physicochemical variability of the dendrimers and their hybrids, this review attempts to discuss a full spectrum of recent advances and strides made by these "perfectly designed structures". An extensive biotech/biomimicry application profiling of dendrimers is provided with focus on complex archetypical designs such as protein biomimicry (angiogenic inhibitors, regenerative hydroxyapatite and collagen) and biotechnology applications. In terms of biotechnological advances, dendrimers have provided distinctive advantages in the fields of biocatalysis, microbicides, artificial lights, mitochondrial function modulation, vaccines, tissue regeneration and repair, antigen carriers and even biosensors. In addition, this review provides overview of the extensive chemo-functionalization opportunities available with dendrimers which makes them a perfect candidate for forming drug conjugates, protein hybrids, bio mimics, lipidic derivatives, metal deposits and nanoconjugates thereby making them the most multifunctional platforms for diverse biotechnological applications.

It is the Era of technology and many countries are adjusting their economy with it. The research on biotechnology is done with a logarithmic rate at different technologies such as pharmacy, agriculture, environment, food, oil, and etc. The relevant research would result in the production of new materials which are released into the environment. In many developed countries biotechnology is regarded as a firm base for economic development and without doubt plays a determined role in humane wealth and well-being, but this technology should be sustainable and controllable. The producer and consumer of biotechnology must think deeply about this matter and take into account the health and sustain ability of earth and the environment. Evaluation of ecological impacts of micro- organisms and manipulated genetically organism should be considered in all countries of the world and such an activities should be regulated and controlled as it was don in Canada under the supervision of Dept

Method for Evaluation of Outage Probability on Random Access Channel in Mobile Communication Systems

Science.gov (United States)

Kollár, Martin

2012-05-01

In order to access the cell in all mobile communication technologies a so called random-access procedure is used. For example in GSM this is represented by sending the CHANNEL REQUEST message from Mobile Station (MS) to Base Transceiver Station (BTS) which is consequently forwarded as an CHANNEL REQUIRED message to the Base Station Controller (BSC). If the BTS decodes some noise on the Random Access Channel (RACH) as random access by mistake (so- called ‘phantom RACH') then it is a question of pure coincidence which èstablishment cause’ the BTS thinks to have recognized. A typical invalid channel access request or phantom RACH is characterized by an IMMEDIATE ASSIGNMENT procedure (assignment of an SDCCH or TCH) which is not followed by sending an ESTABLISH INDICATION from MS to BTS. In this paper a mathematical model for evaluation of the Power RACH Busy Threshold (RACHBT) in order to guaranty in advance determined outage probability on RACH is described and discussed as well. It focuses on Global System for Mobile Communications (GSM) however the obtained results can be generalized on remaining mobile technologies (ie WCDMA and LTE).

The diversity and complexity of biotechnological applications are constantly increasing, with ever expanding ranges of production hosts, cultivation conditions and measurement tasks. Consequently, many analytical and cultivation systems for biotechnology and bioprocess engineering, such as microfluidic devices or bioreactors, are tailor-made to precisely satisfy the requirements of specific measurements or cultivation tasks. Additive manufacturing (AM) technologies offer the possibility of fabricating tailor-made 3D laboratory equipment directly from CAD designs with previously inaccessible levels of freedom in terms of structural complexity. This review discusses the historical background of these technologies, their most promising current implementations and the associated workflows, fabrication processes and material specifications, together with some of the major challenges associated with using AM in biotechnology/bioprocess engineering. To illustrate the great potential of AM, selected examples in microfluidic devices, 3D-bioprinting/biofabrication and bioprocess engineering are highlighted. Copyright © 2017 Elsevier B.V.

The analysis of patent activity is one methodology used for technological monitoring. In this paper, the activity of biotechnology-related patents in Brazil were analyzed through 30 International Patent Classification (IPC) codes published by the Organization for Economic Cooperation and Development (OECD). We developed a program to analyse the dynamics of the major patent applicants, countries and IPC codes extracted from the Brazilian Patent Office (INPI) database. We also identified Brazilian patent applicants who tried to expand protection abroad via the Patent Cooperation Treaty (PCT). We had access to all patents published online at the INPI from 1975 to July 2010, including 9,791 biotechnology patent applications in Brazil, and 163 PCTs published online at World Intellectual Property Organization (WIPO) from 1997 to December 2010. To our knowledge, there are no other online reports of biotechnology patents previous to the years analyzed here. Most of the biotechnology patents filed in the INPI (10.9%) concerned measuring or testing processes involving nucleic acids. The second and third places belonged to patents involving agro-technologies (recombinant DNA technology for plant cells and new flowering plants, i.e. angiosperms, or processes for obtaining them, and reproduction of flowering plants by tissue culture techniques). The majority of patents (87.2%) were filed by nonresidents, with USA being responsible for 51.7% of all biotechnology patents deposited in Brazil. Analyzing the resident applicants per region, we found a hub in the southeast region of Brazil. Among the resident applicants for biotechnology patents filed in the INPI, 43.5% were from São Paulo, 18.3% were from Rio de Janeiro, and 9.7% were from Minas Gerais. Pfizer, Novartis, and Sanofi were the largest applicants in Brazil, with 339, 288, and 245 biotechnology patents filed, respectively. For residents, the largest applicant was the governmental institution FIOCRUZ (Oswaldo Cruz

Holmes, R.G.G.; Benson, J.

1996-01-01

BNFL have invested in a Biotechnology programme to address waste treatment problems. The use of biotechnology to destroy organic pollutants is well known and has been successfully employed both in-situ and ex-situ. The BNFL approach has been to concentrate on the interaction of microbial systems with inorganic materials. This study has resulted in two major programmes of work that show every indication of being suitable for large scale application. The first programme of work investigated using, to decontaminate concrete surfaces, the phenomena of concrete degradation by sulphur oxidizing bacteria. Laboratory tests proved encouraging and have resulted in a Co-operative Research and Development Agreement (CRADA), between BNFL and Lockheed Martin Idaho Technologies Company for the INEL site. The CRADA will lead to a demonstration of the technology. The second major area of investigation is the development of an integrated bioremediation process for the removal and recovery of toxic heavy metals from contaminated land. The two stage process, which can be employed in an in-situ or ex-situ mode, involves the use of indigenous micro-organisms to generate sulphuric acid and environmental consortia to generate hydrogen sulphide. This project has reached the point of field trials. Results from both programmes will be presented and their applications at nuclear sites detailed

The second part of the biotechnology awareness study focused on health sciences libraries and how well they are meeting the needs of biotechnologists working in the study's nine medical centers. A survey was conducted over a three-month period to assess the demand for biotechnology-related reference services at nine libraries and the sources the librarians used to answer the questions. Data on monographic and current serial holdings were also collected. At the end of the survey period, librarians were asked for their perceptions about biotechnology research at their institutions and in their geographic areas. Their responses were compared to the responses the scientists at the nine schools gave to the same or similar questions. Results showed few biotechnology-related reference questions were asked of the librarians. The recorded questions dealt with a range of biotechnology subjects. MEDLINE was used to answer 77% of the questions received during the survey period. More detailed notes in MeSH and a guide to online searching for biotechnology topics were suggested by the librarians as ways to improve reference service to this group of researchers. Journal collections were generally strong, with libraries owning from 50% to 87% of the titles on a core list of biotechnology journals compiled for this study. All libraries subscribed to the five titles most often cited by the scientists surveyed. Generally, librarians were unaware of the biotechnology-related research being done on their campuses or in their geographic areas. PMID:1998819

Religious voices in biotechnology: the case of gene patenting.

Science.gov (United States)

Hanson, M J

1999-01-01

On 18 May 1995, nearly 200 religious leaders joined with leading biotechnology critic Jeremy Rifkin in a press conference named the "Joint Appeal against Human and Animal Patenting," a move that many within the biotechnology industry could only interpret as seeking to inhibit biotechnological advance. What moral and religious concerns motivated this challenge to patenting? How could the biotechnology industry understand and respectfully attend to these concerns? What values were at play in the debates that followed the joint appeal? What lessons for future dialogue can be learned from attempts at conversation between the opposing positions? This essay is a report from a Hastings Center research project that accepted the task of addressing these questions. Specifically, the project focused on the patenting of human genetic material, a subset of the issues raised by the joint appeal.

Clinical pharmacology of sibutramine hydrochloride (BTS 54524), a new antidepressant, in healthy volunteers.

Science.gov (United States)

King, D J; Devaney, N

1988-01-01

The cardiovascular, anticholinergic and central effects of single doses of 30, 45 and 60 mg of sibutramine hydrochloride (BTS 54524), a new potential antidepressant, were compared with amitriptyline (50 mg) and placebo given at weekly intervals in a randomised design to six healthy male volunteers. Sibutramine was associated with increases in both supine heart rate and systolic blood pressure at 1, 2 and 6 h after 60 mg (P less than 0.05). Amitriptyline caused a significant 50-60% decrease in salivation compared with placebo at 2 and 6 h but there were no changes with sibutramine. No significant changes in pupil size were detected with either drug. Visual analogue rating scales (VARS) revealed significant drowsiness with amitriptyline but neither sedative nor stimulant effects with sibutramine. Impairments of simple auditory and visual reaction times, visual two-choice reaction time, finger tapping and trail making, measured using an automated test battery, occurred with amitriptyline compared with sibutramine. If sibutramine proves to be an effective antidepressant it should be devoid of anticholinergic or central depressant effects. Chronic dosage studies are indicated to evaluate the clinical significance of its cardiovascular effects. PMID:3207566

Biotechnological Applications of Microbial (Per)chlorate Reduction.

Science.gov (United States)

Wang, Ouwei; Coates, John D

2017-11-24

While the microbial degradation of a chloroxyanion-based herbicide was first observed nearly ninety years ago, only recently have researchers elucidated the underlying mechanisms of perchlorate and chlorate [collectively, (per)chlorate] respiration. Although the obvious application of these metabolisms lies in the bioremediation and attenuation of (per)chlorate in contaminated environments, a diversity of alternative and innovative biotechnological applications has been proposed based on the unique metabolic abilities of dissimilatory (per)chlorate-reducing bacteria (DPRB). This is fueled in part by the unique ability of these organisms to generate molecular oxygen as a transient intermediate of the central pathway of (per)chlorate respiration. This ability, along with other novel aspects of the metabolism, have resulted in a wide and disparate range of potential biotechnological applications being proposed, including enzymatic perchlorate detection; gas gangrene therapy; enhanced xenobiotic bioremediation; oil reservoir bio-souring control; chemostat hygiene control; aeration enhancement in industrial bioreactors; and, biogenic oxygen production for planetary exploration. While previous reviews focus on the fundamental science of microbial (per)chlorate reduction (for example see Youngblut et al., 2016), here, we provide an overview of the emerging biotechnological applications of (per)chlorate respiration and the underlying organisms and enzymes to environmental and biotechnological industries.

Independent Biotechnology: The Innovation-Regulation Dilemma

2016-11-03

The Center for Global Security Research at Lawrence Livermore National Laboratory convened a workshop on August 19, 2016 to consider “Independent Biotechnology: The Innovation-­Regulation Dilemma”. The topic was motivated by the observation that non-­government funded biotechnology research and development activities have grown and diversified tremendously over the past decade. This sector encompasses a broad range of actors and activities: individuals with private laboratories, community “hackerspaces,” biotechnology incubators, and individual startups. Motivations and aspirations are diverse and include such things as personal curiosity, community education, the invention of new products or services, and even the realization of certain economic, political, or social goals. One driving force is the “democratization” of ever more powerful biological technologies, allowing individual citizens and groups access to capabilities that have traditionally only been available to researchers in universities, research institutes, national laboratories, and large commercial concerns. Another is the rise of alternative financing mechanisms such as “crowdsourcing,” which ostensibly provide greater freedom to innovate, and greater public visibility, but entail looser management oversight and transparency.

Development of health biotechnology in developing countries: can private-sector players be the prime movers?

Science.gov (United States)

Abuduxike, Gulifeiya; Aljunid, Syed Mohamed

2012-01-01

Health biotechnology has rapidly become vital in helping healthcare systems meet the needs of the poor in developing countries. This key industry also generates revenue and creates employment opportunities in these countries. To successfully develop biotechnology industries in developing nations, it is critical to understand and improve the system of health innovation, as well as the role of each innovative sector and the linkages between the sectors. Countries' science and technology capacities can be strengthened only if there are non-linear linkages and strong interrelations among players throughout the innovation process; these relationships generate and transfer knowledge related to commercialization of the innovative health products. The private sector is one of the main actors in healthcare innovation, contributing significantly to the development of health biotechnology via knowledge, expertise, resources and relationships to translate basic research and development into new commercial products and innovative processes. The role of the private sector has been increasingly recognized and emphasized by governments, agencies and international organizations. Many partnerships between the public and private sector have been established to leverage the potential of the private sector to produce more affordable healthcare products. Several developing countries that have been actively involved in health biotechnology are becoming the main players in this industry. The aim of this paper is to discuss the role of the private sector in health biotechnology development and to study its impact on health and economic growth through case studies in South Korea, India and Brazil. The paper also discussed the approaches by which the private sector can improve the health and economic status of the poor. Copyright © 2012 Elsevier Inc. All rights reserved.

Cryptogenic fibrosing alveolitis and lung cancer: the BTS study.

Science.gov (United States)

Harris, J M; Johnston, I D A; Rudd, R; Taylor, A J Newman; Cullinan, P

2010-01-01

The risk of lung cancer is often reported to be increased for patients with cryptogenic fibrosing alveolitis (CFA). Vital status was sought for all 588 members of the British Thoracic Society (BTS) cryptogenic fibrosing alveolitis (CFA) study 11 years after entry to the cohort. Observed deaths due to lung cancer were compared with expected deaths using age-, sex- and period-adjusted national rates. The roles of reported asbestos exposure and smoking were also investigated. 488 cohort members (83%) had died; 46 (9%) were certified to lung cancer (ICD9 162). The standardised mortality ratio (SMR) was 7.4 (95% CI 5.4 to 9.9). Stratified analysis showed increased lung cancer mortality among younger subjects, men and ever smokers. Using an independent expert panel, 25 cohort members (4%) were considered to have at least moderate exposure to asbestos; the risk of lung cancer was increased for these subjects (SMR 13.1 (95% CI 3.6 to 33.6)) vs 7.2 (95% CI 5.2 to 9.7) for those with less or no asbestos exposure). Ever smoking was reported by 448 (73%) of the cohort and was considerably higher in men than in women (92% vs 49%; p<0.001). Most persons who died from lung cancer were male (87%), and all but two (96%) had ever smoked. Ever smokers presented at a younger age (mean 67 vs 70 years; p<0.001) and with less breathlessness (12% smokers reported no breathlessness vs 5% never smokers; p = 0.02). These findings confirm an association between CFA and lung cancer although this relationship may not be causal. The high rate of smoking and evidence that smokers present for medical attention earlier than non-smokers suggest that smoking could be confounding this association.

As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

Normative ethical considerations of growth of the marine biotechnology and aquaculture disciplines in biopharming, food production, and marine products commercialization from a bioethical perspective have been limited. This paucity of information begs the question of what constitutes a bioethical approach (i.e., respect for individuals or autonomy; beneficence, nonmaleficence, and justice) to marine biotechnology and aquaculture, and whether it is one that is appropriate for consideration. Currently, thoughtful discussion on the bioethical implications of use, development, and commercialization of marine organisms or their products, as well as potential environmental effects, defaults to human biomedicine as a model. One must question the validity of using human bioethical principlism moral norms for appropriating a responsible marine biotechnology and aquaculture ethic. When considering potential impacts within these disciplines, deference must be given to differing value systems in order to find common ground to advance knowledge and avoid emotive impasses that can hinder the science and its application. The import of bioethical considerations when conducting research and/or production is discussed. This discussion is directed toward applying bioethical principles toward technology used for food, biomedical development (e.g., biopharming), or as model species for advancement of knowledge for human diseases.

Biodiesel has received much attention in recent years. Although numerous reports are available on the production of biodiesel from vegetable oils of terraneous oil-plants, such as soybean, sunflower and palm oils, the production of biodiesel from microalgae is a newly emerging field. Microalgal biotechnology appears to possess high potential for biodiesel production because a significant increase in lipid content of microalgae is now possible through heterotrophic cultivation and genetic engineering approaches. This paper provides an overview of the technologies in the production of biodiesel from microalgae, including the various modes of cultivation for the production of oil-rich microalgal biomass, as well as the subsequent downstream processing for biodiesel production. The advances and prospects of using microalgal biotechnology for biodiesel production are discussed. (author)

Reproductive biotechnology has manifold applications and includes a great innovation potential in livestock. Due to the global changes the new findings and techniques can aid to meet the future challenges. The use of biotechnology in animal production can guarantee enough high quality food for the whole population. Genetic resources of animals can be preserved via sperm and embryo banking. Early diagnosis of hereditary defects, generation of offspring with predetermined sex and the avoidance of animal transports for breeding employing shipment of frozen embryos will improve animal welfare. A special application is the use of animal models for human assisted reproductive technologies. Therefore, not only in Germany research related to the methodologies in reproductive biotechnology and their improvement need to be supported.

Agricultural biotechnology and smallholder farmers in developing countries.

Science.gov (United States)

Anthony, Vivienne M; Ferroni, Marco

2012-04-01

Agricultural biotechnology holds much potential to contribute towards crop productivity gains and crop improvement for smallholder farmers in developing countries. Over 14 million smallholder farmers are already benefiting from biotech crops such as cotton and maize in China, India and other Asian, African and Central/South American countries. Molecular breeding can accelerate crop improvement timescales and enable greater use of diversity of gene sources. Little impact has been realized to date with fruits and vegetables because of development timescales for molecular breeding and development and regulatory costs and political considerations facing biotech crops in many countries. Constraints to the development and adoption of technology-based solutions to reduce yield gaps need to be overcome. Full integration with broader commercial considerations such as farmer access to seed distribution systems that facilitate dissemination of improved varieties and functioning markets for produce are critical for the benefits of agricultural biotechnology to be fully realized by smallholders. Public-private partnerships offer opportunities to catalyze new approaches and investment while accelerating integrated research and development and commercial supply chain-based solutions.

Full Text Available Population growth in the context of limited land resources makes the global scientific society research new ways to increase the agricultural yields. Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

Fossil resources, i.e. concentrated carbon from biomass, have been irrecoverably exhausted through modern industrial civilization in the last two hundred years. Serious consequences including crises in resources, environment and energy, as well as the pressing need for direct and indirect exploitation of solar energy, pose challenges to the science and technology community of today. Bioenergy, bulk chemicals, and biomaterials could be produced from renewable biomass in a biorefinery via biocatalysis. These sustainable industries will match the global mass cycle, creating a new form of civilization with new industries and agriculture driven by solar energy. Industrial biotechnology is the dynamo of a bioeconomy, leading to a new protocol for production of energy, bulk chemicals, and materials. This new mode of innovation will place the industry at center stage supported by universities and research institutes. Creativity in industrial biotechnology will be promoted and China will successfully follow the road to green modernization. China's rapid economic development and its traditional capacity in fermentation will place it in an advantageous position in the industrial biotechnology revolution. The development and current status of industrial biotechnology in China are summarized herein.

2013-06-25

This article traces back thirty years of biotechnology research sponsored by the European Union (EU). It outlines the crucial role played by De Nettancourt, Goffeau and Van Hoeck to promote and prepare the first European programme on biotechnology (1982-1986) run by the European Commission. Following this first biotechnology programme, others followed until the current one, part of the seventh Framework Programme for Research, Technological Development and Demonstration (2007-2013) (FP7). Particular attention is given to the statutory role of the European institutions in the design and orientation of the successive biotechnology programmes, compared to the more informal-yet visionary-role of key individuals upstream to any legislative decision. Examples of success stories and of the role of the biotechnology programmes in addressing societal issues and industrial competitiveness are also presented. Finally, an outline of Horizon 2020, the successor of FP7, is described, together with the role of biotechnology in building the bioeconomy. Copyright © 2012 Elsevier B.V. All rights reserved.

A CYP21A2 based whole-cell system in Escherichia coli for the biotechnological production of premedrol.

Science.gov (United States)

Brixius-Anderko, Simone; Schiffer, Lina; Hannemann, Frank; Janocha, Bernd; Bernhardt, Rita

2015-09-15

Synthetic glucocorticoids like methylprednisolone (medrol) are of high pharmaceutical interest and represent powerful drugs due to their anti-inflammatory and immunosuppressive effects. Since the chemical hydroxylation of carbon atom 21, a crucial step in the synthesis of the medrol precursor premedrol, exhibits a low overall yield because of a poor stereo- and regioselectivity, there is high interest in a more sustainable and efficient biocatalytic process. One promising candidate is the mammalian cytochrome P450 CYP21A2 which is involved in steroid hormone biosynthesis and performs a selective oxyfunctionalization of C21 to provide the precursors of aldosterone, the main mineralocorticoid, and cortisol, the most important glucocorticoid. In this work, we demonstrate the high potential of CYP21A2 for a biotechnological production of premedrol, an important precursor of medrol. We successfully developed a CYP21A2-based whole-cell system in Escherichia coli by coexpressing the cDNAs of bovine CYP21A2 and its redox partner, the NADPH-dependent cytochrome P450 reductase (CPR), via a bicistronic vector. The synthetic substrate medrane was selectively 21-hydroxylated to premedrol with a max. yield of 90 mg L(-1) d(-1). To further improve the biocatalytic activity of the system by a more effective electron supply, we exchanged the CPR with constructs containing five alternative redox systems. A comparison of the constructs revealed that the redox system with the highest endpoint yield converted 70 % of the substrate within the first 2 h showing a doubled initial reaction rate compared with the other constructs. Using the best system we could increase the overall yield of premedrol to a maximum of 320 mg L(-1) d(-1) in shaking flasks. Optimization of the biotransformation in a bioreactor could further improve the premedrol gain to a maximum of 0.65 g L(-1) d(-1). We successfully established a CYP21-based whole-cell system for the biotechnological production of premedrol

Kumar, Satyendra; Pahujani, Shweta; Ola, R P; Kanwar, S S; Gupta, Reena

2006-06-01

A lipase from the thermophilic isolate Bacillus coagulans BTS-3 was produced and purified. The enzyme was purified 40-fold to homogeneity by ammonium sulfate precipitation and DEAE-Sepharose column chromatography. Its molecular weight was 31 kDa on SDS-PAGE. The purified lipase was immobilized on silica and its binding efficiency was found to be 60%. The enzyme took 60 min to bind maximally onto the support. The pH and temperature optima of immobilized lipase were same as those of the free enzyme, i.e. 8.5 and 55 degrees C, respectively. The immobilized enzyme had shown marked thermostability on the elevated temperatures of 55, 60, 65 and 70 degrees C. The immobilized enzyme was reused for eigth cycles as it retained almost 80% of its activity. The catalytic activity of immobilized enzyme was enhanced in n-hexane and ethanol. The immobilized enzyme when used for esterification of ethanol and propionic acid showed 96% conversion in n-hexane in 12 h at 55 degrees C.

Scientific underpinnings of biotechnology regulatory frameworks.

Science.gov (United States)

Gleim, Savannah; Smyth, Stuart J

2018-05-25

Part of what is presently missing at domestic regulatory levels (and that is important at the international level as well) is a detailed understanding of what the rules of, and for, regulation should be, who the actors, stakeholders and major decision makers are and finally, how to get agreement about the rules. Greater insights into the system of rules that underpin regulatory frameworks for agri-food and biotechnology products in genetically modified (GM) crop- adopting nations will provide value by clarifying the evidence used to commercialize these technologies. This article examines the public documents available from Canada, the United States, the European Union and the Organisation for Economic Cooperation and Development regarding the development of regulatory risk assessment frameworks for products of biotechnology to determine what science grounds these frameworks. The documentation used to provide the initial structure to the existing regulatory frameworks identifies the linkages, connections and relationships that exist between science, risk assessment and regulatory policy. The relationship between risk and regulation has never been more critical to the commercialization of innovative agricultural products. Documenting the role of science-based risk assessment in regulations and how this has changed over the 20 years of experience in regulating GM crops will identify changes in the risk/regulation relationship.

Review of biotechnology applications to nuclear waste treatment

International Nuclear Information System (INIS)

Ashley, N.V.; Roach, D.J.W.

1990-01-01

This paper gives an overview of the feasibility of the application of biotechnology to nuclear waste treatment. Many living and dead organisms accumulate heavy metals and radionuclides. The controlled use of this phenomenon forms the basis for the application of biotechnology to the removal of radionuclides from nuclear waste streams. An overview of biotechnology areas, namely the use of biopolymers and biosorption using biomass applicable to the removal of radionuclides from industrial nuclear effluents is given. The potential of biomagnetic separation technology, genetic engineering and monoclonal antibody technology is also to be examined. The most appropriate technologies to develop for radionuclide removal in the short term appear to be those based on biosorption of radionuclides by biomass and the use of modified and unmodified biopolymers in the medium term.

Rittmann, Bruce E

2006-06-01

Microbial ecology and environmental biotechnology are inherently tied to each other. The concepts and tools of microbial ecology are the basis for managing processes in environmental biotechnology; and these processes provide interesting ecosystems to advance the concepts and tools of microbial ecology. Revolutionary advancements in molecular tools to understand the structure and function of microbial communities are bolstering the power of microbial ecology. A push from advances in modern materials along with a pull from a societal need to become more sustainable is enabling environmental biotechnology to create novel processes. How do these two fields work together? Five principles illuminate the way: (i) aim for big benefits; (ii) develop and apply more powerful tools to understand microbial communities; (iii) follow the electrons; (iv) retain slow-growing biomass; and (v) integrate, integrate, integrate.

Stagg, Nicola J; Ghantous, Hanan N; Ladics, Gregory S; House, Robert V; Gendel, Steven M; Hastings, Kenneth L

2013-01-01

A workshop entitled "Challenges and Opportunities in Evaluating Protein Allergenicity across Biotechnology Industries" was held at the 51st Annual Meeting of the Society of Toxicology (SOT) in San Francisco, California. The workshop was sponsored by the Biotechnology Specialty Section of SOT and was designed to present the science-based approaches used in biotechnology industries to evaluate and regulate protein allergenicity. A panel of experts from industry and government highlighted the allergenicity testing requirements and research in the agricultural, pharmaceutical/biopharma, and vaccine biotechnology industries and addressed challenges and opportunities for advancing the science of protein allergenicity. The main learning from the workshop was that immunoglobulin E-mediated allergenicity of biotechnology-derived products is difficult to assess without human data. The approaches currently being used to evaluate potential for allergenicity across biotechnology industries are very different and range from bioinformatics, in vitro serology, in vivo animal testing, in vitro and in vivo functional assays, and "biosimilar" assessments (ie, biotherapeutic equivalents to innovator products). The challenge remains with regard to the different or lack of regulatory requirements for allergenicity testing across industries, but the novel approaches being used with bioinformatics and biosimilars may lead to opportunities in the future to collaborate across biotechnology industries.

Large-scale efforts to sequence aquatic genomes and metagenomes, as well as campaigns to isolate new organisms and culture-based screenings, are helping to push the boundaries of known organisms. Mass spectrometry-based proteomics can complement 16S gene sequencing in the effort to discover new organisms of potential relevance to blue biotechnology by facilitating the rapid screening of microbial isolates and by providing in depth profiles of the proteomes and metaproteomes of marine organisms, both model cultivable isolates and, more recently, exotic non-cultivable species and communities. Proteomics has already contributed to blue biotechnology by identifying aquatic proteins with potential applications to food fermentation, the textile industry, and biomedical drug development. In this review, we discuss historical developments in blue biotechnology, the current limitations to the known marine biosphere, and the ways in which mass spectrometry can expand that knowledge. We further speculate about directions that research in blue biotechnology will take given current and near-future technological advancements in mass spectrometry. Copyright © 2014 Elsevier B.V.

Since 1990s Malaysia aspired to make biotechnology and bioeconomy as her engines of economic growth to utlise the abundance of natural resources and biodiversity. The public sector plays an integral role in developing the sector and various incentives are in place for the private sector to be actively involved and to forge collaboration with the public sector. The country launched its National Biotechnology Policy in 2005 and later launched its National Bioeconomy Programme in 2010 to become the first country in South East Asia and second in Asia after China to have such an initiative. Malaysia is also very proactive in its biosafety law and regulations and has most of the related legal instrument in place. A lot of success has been recorded since the inception of the National Biotechnology Policy in terms of job creation, contribution to GDP through biobusinesses and investment from foreign companies, but the sector is not spared from challenges too. Due to the nature of the discipline that is multidisciplinary and that requires huge amount of investment, expertise and political will, there are a lot of barriers before the country emerges as a bioeconomy player. This paper discusses the public policies, initiatives and funding mechanisms in place in Malaysia that drive its research, development and commercialisation in the area of biotechnology and bioeconomy. The authors also discuss the challenges faced in Malaysia in implementing the policies. Copyright © 2017 Elsevier B.V. All rights reserved.

Vinto, Natale; Tropea, Mauro; Fazio, Peppino; Voznak, Miroslav

2014-05-01

Recent years have been characterized by an increase in the air traffic. More attention over micro-economic and macroeconomic indexes would be strategic to gather and enhance the safety of a flight and customer needing, for communicating by wireless handhelds on-board aircrafts. Thus, European Telecommunications Standards Institute (ETSI) proposed a GSM On Board (GSMOBA) system as a possible solution, allowing mobile terminals to communicate through GSM system on aircraft, avoiding electromagnetic interferences with radio components aboard. The main issues are directly related with interferences that could spring-out when mobile terminals attempt to connect to ground BTS, from the airplane. This kind of system is able to resolve the problem in terms of conformance of Effective Isotropic Radiated Power (EIRP) limits, defined outside the aircraft, by using an On board BTS (OBTS) and modeling the relevant key RF parameters on the air. The main purpose of this work is to illustrate the state-of-the-art of literature and previous studies about the problem, giving also a good detail of technical and normative references.

A thermophilic isolate Bacillus coagulans BTS-3 produced an extracellular alkaline lipase, the production of which was substantially enhanced when the type of carbon source, nitrogen source, and the initial pH of culture medium were consecutively optimized. Lipase activity 1.16 U/ml of culture medium was obtained in 48 h at 55 degrees C and pH 8.5 with refined mustard oil as carbon source and a combination of peptone and yeast extract (1:1) as nitrogen sources. The enzyme was purified 40-fold to homogeneity by ammonium sulfate precipitation and DEAE-Sepharose column chromatography. Its molecular weight was 31 kDa on SDS-PAGE. The enzyme showed maximum activity at 55 degrees C and pH 8.5, and was stable between pH 8.0 and 10.5 and at temperatures up to 70 degrees C. The enzyme was found to be inhibited by Al3+, Co2+, Mn2+, and Zn2+ ions while K+, Fe3+, Hg2+, and Mg2+ ions enhanced the enzyme activity; Na+ ions have no effect on enzyme activity. The purified lipase showed a variable specificity/hydrolytic activity towards various 4-nitrophenyl esters.

UK biotechnology companies lead the way for Europe

Energy Technology Data Exchange (ETDEWEB)

1984-05-01

A number of new well-structured biotechnology companies have been launched in Britain over the last few years, e.g. Imperial Biotechnology, IQ(Bio) and Celltech, while Wellcome and Searle (U.K.) are established firms, keeping up with the new technology. Imperial Biotechnology, with its accent on development rather than research and making products not in anyone else's catalogue, has produced a whole range of enzymes, biopolymers, antibiotics, and human proteins under contract. Its long term objective is to develop its own bioproducts. IQ(Bio) is poised to enter the diagnostic big league with its enzyme-linked immunoassay (Aelia) technology and intends to pursue opportunities where there is a strict regulatory climate prohibiting the growth of radioimmunoassays, e.g. France and Japan. It plans to produce kits that a doctor can use simply and give results in less than 30 minutes. Celltech has a culture products division which supplies large quantities of monoclonal antibodies, it has a diagnostics and health care research section, a speciality chemicals area and an industrial microbiology sector. Wellcome Biotechnology has an interferon programme which includes a broad range of chemical trials in the anticancer and antiviral areas. The company could supply the entire world market for interferon using cell culture and produces a very large range of conventional vaccines. Searle uses biotechnology as just another means of producing new drugs as they have a large drug development machine in place. A considerable amount of process development work has focused on Searle's artificial sweetener, aspartame, and they are looking at all the technical approaches to aspartame production.

Full Text Available The aim of this study is to compare the graphene produced using a biotechnological method (Escherichia coli with the graphene produced by Hummers’ method (a chemical method and to study the effect on the energy consumption and environment. The results indicated that the chemical reduction process has higher energy consumption, approximately 1642 Wh, than the energy consumption of the biotechnological reduction process, which is 5 Wh. The potential of global warming (GWP 100 improved by 71% using the biotechnological route for the production of graphene. Abiotic depletion, the photochemical ozone creation potential, and marine aquatic ecotoxicity potential were improved when the biological route was employed, compared with the chemical route. The eutrophication potential, terrestrial ecotoxicity, and ozone depletion layer changed very little since the main variables involved in the production of graphene oxide and waste management are the same. The biotechnological method can be considered a green technique for the production of graphene, especially given the reduction in the negative effects on global warming, abiotic depletion, the photochemical ozone creation potential, and the marine aquatic ecotoxicity potential.

Masotti, Andrea; Caporali, Andrea

2013-12-18

Carbon nanotubes (CNTs) have been widely studied for their potential applications in many fields from nanotechnology to biomedicine. The preparation of magnetic CNTs (Mag-CNTs) opens new avenues in nanobiotechnology and biomedical applications as a consequence of their multiple properties embedded within the same moiety. Several preparation techniques have been developed during the last few years to obtain magnetic CNTs: grafting or filling nanotubes with magnetic ferrofluids or attachment of magnetic nanoparticles to CNTs or their polymeric coating. These strategies allow the generation of novel versatile systems that can be employed in many biotechnological or biomedical fields. Here, we review and discuss the most recent papers dealing with the preparation of magnetic CNTs and their application in biomedical and biotechnological fields.

Interface of nuclear and biotechnologies

International Nuclear Information System (INIS)

Castro Diaz-Balart, F.

2005-01-01

Addressing nuclear and biotechnologies in the International Year of Physics should begin by highlighting the important role that this science has played in the development of both branches of science and technologies. The first as a direct consequence of the Theory of Relativity, the further was considerably influenced by Schroedinger's remarks that there must be a code of some kind that allowed molecules in cells to carry information, making a connection between genes and proteins. Both, like any highly technical endeavor, have also in common that the use of technologies demands a vast accumulation of knowledge, i.e. volumes of scientific research, engineering analysis, strict regulatory controls and a huge amount of information combined with a complex assortment of people with the required educational background, expertise and skills to master it. This presentation briefly explores the ways in which nuclear technology has been used in the last decades of the 20th century in the field of biomedicine applications, which includes the use of radiation to obtain accurate images as well as in diagnosis and therapy. The paper looks at the present prospects of some nuclear methods and instrumentation in the so-called Red biotechnology and its genetically engineered therapeutic agents and diagnostic tests as well as some related perspectives in the field of bioinformatics. As an example of biotechnology being successfully applied to health problems in developing countries the presentation gives an outlook of relevant Cuban achievements in this field. (author)

Biotechnologies for the management of genetic resources for food and agriculture.

Science.gov (United States)

Lidder, Preetmoninder; Sonnino, Andrea

2012-01-01

In recent years, the land area under agriculture has declined as also has the rate of growth in agricultural productivity while the demand for food continues to escalate. The world population now stands at 7 billion and is expected to reach 9 billion in 2045. A broad range of agricultural genetic diversity needs to be available and utilized in order to feed this growing population. Climate change is an added threat to biodiversity that will significantly impact genetic resources for food and agriculture (GRFA) and food production. There is no simple, all-encompassing solution to the challenges of increasing productivity while conserving genetic diversity. Sustainable management of GRFA requires a multipronged approach, and as outlined in the paper, biotechnologies can provide powerful tools for the management of GRFA. These tools vary in complexity from those that are relatively simple to those that are more sophisticated. Further, advances in biotechnologies are occurring at a rapid pace and provide novel opportunities for more effective and efficient management of GRFA. Biotechnology applications must be integrated with ongoing conventional breeding and development programs in order to succeed. Additionally, the generation, adaptation, and adoption of biotechnologies require a consistent level of financial and human resources and appropriate policies need to be in place. These issues were also recognized by Member States at the FAO international technical conference on Agricultural Biotechnologies for Developing Countries (ABDC-10), which took place in March 2010 in Mexico. At the end of the conference, the Member States reached a number of key conclusions, agreeing, inter alia, that developing countries should significantly increase sustained investments in capacity building and the development and use of biotechnologies to maintain the natural resource base; that effective and enabling national biotechnology policies and science-based regulatory frameworks can

. Therefore, algal production systems need to be improved and harvesting systems need to be more effective in order for their industrial applications to become more competitive and economically viable. Besides, a reduction of the production cost of microalgal lipids can be achieved by combining lipid production with other commercial applications. The combined production of bioactive products and lipids, when possible, can support the commercial viability of both processes. Hydrophobic compounds can be extracted simultaneously with lipids and then purified, while hydrophilic compounds such as proteins and sugars may be extracted from the defatted biomass. The microalgae also have applications in environmental biotechnology since they can be used for bioremediation of wastewater and to monitor environmental toxicants. Algal biomass produced during wastewater treatment may be further valorized in the biofuel manufacture. It is anticipated that the high microalgal lipid potential will force research towards finding effective ways to manipulate biochemical pathways involved in lipid biosynthesis and towards cost effective algal cultivation and harvesting systems, as well.

Biotechnological reduction of sulfide in an industrial primary wastewater treatment system: A sustainable and successful case study

Energy Technology Data Exchange (ETDEWEB)

Rajamani, S. [Central Leather Research Institute, Madras (India)

1996-12-31

The leather industry is an important export-oriented industry in India, with more than 3,000 tanneries located in different clusters. Sodium sulfide, a toxic chemical, is used in large quantities to remove hair and excess flesh from hides and skins. Most of the sodium sulfide used in the process is discharged as waste in the effluent, which causes serious environmental problems. Reduction of sulfide in the effluent is generally achieved by means of chemicals in the pretreatment system, which involves aerobic mixing using large amounts of chemicals and high energy, and generating large volumes of sludge. A simple biotechnological system that uses the residual biosludge from the secondary settling tank was developed, and the commercial-scale application established that more than 90% of the sulfide could be reduced in the primary treatment system. In addition to the reduction of sulfide, foul smells, BOD and COD are reduced to a considerable level. 3 refs., 2 figs., 1 tab.

Undoubtedly, biotechnology has a tremendous impact on our daily lives. As a result of this and in parallel to the advancement of knowledge in this field of applied research, consumer awareness of the potential benefits and risks of this technology has steadily increased, leading to a thorough investigation of the public perception of biotechnology in the past years. Indeed, it has become clear that it is in the general interest of science and especially of applied research to inform the public of its advances. A promising next step is to strengthen biotechnology communication in scholastic institutions. In this paper, we investigate the perception of biotechnology in a specific target group, namely high-school students in the 16-20-year-old age range. We conducted a questionnaire-based survey on a total of 1410 students in six European countries to investigate students' perception, concern, scientific knowledge, and awareness. Our data revealed some unexpected patterns of acceptance and concern about biotechnology. Knowledge analysis indicated that pupils lack specific knowledge about biotechnological applications and their interest in biotechnology appeared to be linked to knowledge. Analysis of specific questions about teaching practices at schools suggests that a better targeted choice in media as vehicles for information together with selected speakers could be instrumental in increasing students' interest in science and more specifically in biotechnology.

Cell-free protein synthesis: applications in proteomics and biotechnology.

Science.gov (United States)

He, Mingyue

2008-01-01

Protein production is one of the key steps in biotechnology and functional proteomics. Expression of proteins in heterologous hosts (such as in E. coli) is generally lengthy and costly. Cell-free protein synthesis is thus emerging as an attractive alternative. In addition to the simplicity and speed for protein production, cell-free expression allows generation of functional proteins that are difficult to produce by in vivo systems. Recent exploitation of cell-free systems enables novel development of technologies for rapid discovery of proteins with desirable properties from very large libraries. This article reviews the recent development in cell-free systems and their application in the large scale protein analysis.

Zhao, Jian

2007-01-01

Plants are one of the most important resources of human foods and medicines. Rapidly increasing knowledge on nutrition, medicine, and plant biotechnology has dramatically changed the concepts about food, health and agriculture, and brought in a revolution on them. Nutritional therapy and phytotherapy have emerged as new concepts and healing systems have quickly and widely spread in recent years. Strong recommendations for consumption of nutraceuticals, natural plant foods, and the use of nutritional therapy and phytotherapy have become progressively popular to improve health, and to prevent and treat diseases. With these trends, improving the dietary nutritional values of fruits, vegetables and other crops or even bioactive components in folk herbals has become targets of the blooming plant biotechnology industry. This review attempts to display and remark on these aspects. It summarizes the progress made on nutraceuticals, nutritional therapy, phytonutrients, phytotherapy, and their related epidemiological investigations and clinical studies. It also covers markets of these health-promoting products and disease-preventing or healing systems, as well as regulations behind them that direct the development of biotechnology study and application. Finally, related patents are listed and briefly analyzed, regarding of plant biotechnological research and progress on transgenic crops to improve nutritional value, phytotherapy efficiency, or to produce pharmaceutically important secondary metabolites or high-valued protein medicines such as vaccines and antibodies.

Utilization of protein-rich residues in biotechnological processes.

Pleissner, Daniel; Venus, Joachim

2016-03-01

A drawback of biotechnological processes, where microorganisms convert biomass constituents, such as starch, cellulose, hemicelluloses, lipids, and proteins, into wanted products, is the economic feasibility. Particularly the cost of nitrogen sources in biotechnological processes can make up a large fraction of total process expenses. To further develop the bioeconomy, it is of considerable interest to substitute cost-intensive by inexpensive nitrogen sources. The aim of this mini-review was to provide a comprehensive insight of utilization methods of protein-rich residues, such as fish waste, green biomass, hairs, and food waste. The methods described include (i) production of enzymes, (ii) recovery of bioactive compounds, and/or (iii) usage as nitrogen source for microorganisms in biotechnological processes. In this aspect, the utilization of protein-rich residues, which are conventionally considered as waste, allows the development of value-adding processes for the production of bioactive compounds, biomolecules, chemicals, and materials.

Understanding public perceptions of biotechnology through the "Integrative Worldview Framework".

Science.gov (United States)

De Witt, Annick; Osseweijer, Patricia; Pierce, Robin

2015-07-03

Biotechnological innovations prompt a range of societal responses that demand understanding. Research has shown such responses are shaped by individuals' cultural worldviews. We aim to demonstrate how the Integrative Worldview Framework (IWF) can be used for analyzing perceptions of biotechnology, by reviewing (1) research on public perceptions of biotechnology and (2) analyses of the stakeholder-debate on the bio-based economy, using the Integrative Worldview Framework (IWF) as analytical lens. This framework operationalizes the concept of worldview and distinguishes between traditional, modern, and postmodern worldviews, among others. Applied to these literatures, this framework illuminates how these worldviews underlie major societal responses, thereby providing a unifying understanding of the literature on perceptions of biotechnology. We conclude the IWF has relevance for informing research on perceptions of socio-technical changes, generating insight into the paradigmatic gaps in social science, and facilitating reflexive and inclusive policy-making and debates on these timely issues. © The Author(s) 2015.

Review of computational fluid dynamics applications in biotechnology processes.

Science.gov (United States)

Sharma, C; Malhotra, D; Rathore, A S

2011-01-01

Computational fluid dynamics (CFD) is well established as a tool of choice for solving problems that involve one or more of the following phenomena: flow of fluids, heat transfer,mass transfer, and chemical reaction. Unit operations that are commonly utilized in biotechnology processes are often complex and as such would greatly benefit from application of CFD. The thirst for deeper process and product understanding that has arisen out of initiatives such as quality by design provides further impetus toward usefulness of CFD for problems that may otherwise require extensive experimentation. Not surprisingly, there has been increasing interest in applying CFD toward a variety of applications in biotechnology processing in the last decade. In this article, we will review applications in the major unit operations involved with processing of biotechnology products. These include fermentation,centrifugation, chromatography, ultrafiltration, microfiltration, and freeze drying. We feel that the future applications of CFD in biotechnology processing will focus on establishing CFD as a tool of choice for providing process understanding that can be then used to guide more efficient and effective experimentation. This article puts special emphasis on the work done in the last 10 years. © 2011 American Institute of Chemical Engineers

The Role of Biotechnology in Sustainable Agriculture: Views and Perceptions among Key Actors in the Swedish Food Supply Chain

Directory of Open Access Journals (Sweden)

Karin Edvardsson Björnberg

2015-06-01

Full Text Available Researchers have put forward agricultural biotechnology as one possible tool for increasing food production and making agriculture more sustainable. In this paper, it is investigated how key actors in the Swedish food supply chain perceive the concept of agricultural sustainability and the role of biotechnology in creating more sustainable agricultural production systems. Based on policy documents and semi-structured interviews with representatives of five organizations active in producing, processing and retailing food in Sweden, an attempt is made to answer the following three questions: How do key actors in the Swedish food supply chain define and operationalize the concept of agricultural sustainability? Who/what influences these organizations’ sustainability policies and their respective positions on agricultural biotechnology? What are the organizations’ views and perceptions of biotechnology and its possible role in creating agricultural sustainability? Based on collected data, it is concluded that, although there is a shared view of the core constituents of agricultural sustainability among the organizations, there is less explicit consensus on how the concept should be put into practice or what role biotechnology can play in furthering agricultural sustainability.

Biotechnological processes are promising alternatives to petrochemical routes for overcoming the challenges of resource depletion in the future in a sustainable way. The strategies of white biotechnology allow the utilization of inexpensive and renewable resources for the production of a broad range of bio-based compounds. Renewable resources, such as agricultural residues or residues from food production, are produced in large amounts have been shown to be promising carbon and/or nitrogen sources. This chapter focuses on the biotechnological production of lactic acid, acrylic acid, succinic acid, muconic acid, and lactobionic acid from renewable residues, these products being used as monomers for bio-based material and/or as food supplements. These five acids have high economic values and the potential to overcome the "valley of death" between laboratory/pilot scale and commercial/industrial scale. This chapter also provides an overview of the production strategies, including microbial strain development, used to convert renewable resources into value-added products.

Biotechnological and molecular approaches for vanillin production: a review.

Science.gov (United States)

Kaur, Baljinder; Chakraborty, Debkumar

2013-02-01

Vanillin is one of the most widely used flavoring agents in the world. As the annual world market demand of vanillin could not be met by natural extraction, chemical synthesis, or tissue culture technology, thus biotechnological approaches may be replacement routes to make production of bio-vanillin economically viable. This review's main focus is to highlight significant aspects of biotechnology with emphasis on the production of vanillin from eugenol, isoeugenol, lignin, ferulic acid, sugars, phenolic stilbenes, vanillic acid, aromatic amino acids, and waste residues by applying fungi, bacteria, and plant cells. Production of biovanillin using GRAS lactic acid bacteria and metabolically engineered microorganisms, genetic organization of vanillin biosynthesis operons/gene cassettes and finally the stability of biovanillin generated through various biotechnological procedures are also critically reviewed in the later sections of the review.

Bokser, O Ia

1999-01-01

Based on the theory of functional systems and a concept of the quantum system of behavior, studies of the quantumsystems were conducted. Their structure, the interaction of biological and technical sections were analyzed. Mathematical, biophysical, and experimental models were designed. The paper shows that biotechnical quantumsystems are involved in the formation of biological feedback. A system with imperative feedback from the programmed and introduced current results of efforts has been developed and put into practice for the self-regulation of muscle tension. Training by using this biological feedback system causes a stable increase in the perception rate of proprioceptive stimulus in examinees (operates, sportsmen, neurological patients).

2018-02-01

Full Text Available The purpose of present research is to demonstrate some trends of development of modeling methods for biotechnology according to contemporary achievements in science and technique. At the beginning the general approaches are outlined, some types of classifications of modeling methods are observed. The role of mathematic methods modeling for biotechnology in present époque of information computer technologies intensive development is studied and appropriate scheme of interrelation of all these spheres is proposed. Further case studies are suggested: some mathematic models in three different spaces (1D, 2D, 3D models are described for processes in living objects of different levels of hierarchic organization. In course of this the main attention was paid to some processes modeling in neurons as well as in their aggregates of different forms, including glioma cell masses (1D, 2D, 3D brain processes models. Starting from the models that have only theoretical importance for today, we describe at the end a model which application may be important for the practice. The work was done after the analysis of approximately 250 current publications in fields of biotechnology, including the authors’ original works.

Biodiversity, biotechnologies and the philosophy of biology.

Science.gov (United States)

Galleni, Lodovico

2004-01-01

The thesis of this paper is that in front of the development of biotechnology and of the capacity of techniques of altering the living, there is still a very old philosophy of biology. A rapid historical view is given where the rise and diffusion of the reductionistic paradigm is presented and the connections between this paradigm and biotechnologies are traced. Curiously biotechnologies are still based on the philosophy of F. Bacon. Then the necessity of a new paradigm in biology based on the recent discoveries of complexity is underlined. It is reminded that the main discovery of science of the XX century is that we are living in a small planet of limited resources and frail equilibriums. This discovery asks for a different view of the scientific progress, more linked to the conservation of the Biosphere than to its alteration. Stability is the task for the future interactions of human-kind with nature. For this reason the relationships between stability and diversity are summarised. Finally, as the species is the main step of Biodiversity, a brief discussion of the problems posed by the altering of species barriers is presented.

Nutrition by design: a review of biotechnology in functional food

Directory of Open Access Journals (Sweden)

Thomas Reynolds

2016-02-01

Full Text Available Medical institutions in industrial and developing countries are increasingly turning to functional foods as intervention in chronic disease. Advances in genetic engineering have provided methods of purposefully designing functional foods and bioactive compound-producing organisms. This literature review examines the recent history of biotechnological applications in functional food, the state of bioagricultural engineering for high-value compound production, and the challenges that developers face in promulgatingfunctional foods from biotechnological sources. Based on the literature reviewed, it is predicted that adding biotechnologically-produced compounds will be more successful in producing novel functional foods. Conclusion: Current functional food application is frequently hampered by a dearth of foods suitable to the purpose. The concurrent advent of biotechnology means that producers and clinicians are not constrained by limited and precarious natural development. Biotechnology has already produced altered dietary staples that can safely induce real health benefits, but the social approval of genetically modified foodstuffs is inconsistent at best. Modifying microalgae to produce micro and macronutrients, for harvest and incorporation into functional food products, provides the ideal specificity and reliability for bioactive compound use. However, its application in biomedical science is impeded by technical difficulty. It remains to be seen if microorganism engineering willbe able to meet the needs of its many stakeholders, including the functional food community. Nonetheless,the prospect of a flourishing functional food market, and the healthier population it will bring about, certainly makes it worth a try.

Development and application of modern agricultural biotechnology in Botswana: the potentials, opportunities and challenges.

Science.gov (United States)

Batlang, Utlwang; Tsurupe, Gorata; Segwagwe, Amogelang; Obopile, Motshwari

2014-07-03

In Botswana, approximately 40% of the population live in rural areas and derive most of their livelihood from agriculture by keeping livestock and practising arable farming. Due to the nature of their farming practises livestock and crops are exposed to diseases and environmental stresses. These challenges offer opportunities for application of biotechnology to develop adaptable materials to the country's environment. On the other hand, the perceived risk of genetically modified organisms (GMOs) has dimmed the promise of the technology for its application in agriculture. This calls for a holistic approach to the application of biotechnology to address issues of biosafety of GMOs. We have therefore assessed the potentials, challenges and opportunities to apply biotechnology with specific emphasis on agriculture, taking cognisance of requirement for its research, development and application in research and teaching institutions. In order to achieve this, resource availability, infrastructure, human and laboratory requirements were analyzed. The analysis revealed that the country has the capacity to carry out research in biotechnology in the development and production of genetically modified crops for food and fodder crops. These will include gene discovery, genetic transformation and development of systems to comply with the world regulatory framework on biosafety. In view of the challenges facing the country in agriculture, first generation biotech crops could be released for production. Novel GM products for development may include disease diagnosis kits, animal disease vaccines, and nutrient use efficiency, drought, and pest and disease resistant food and fodder crops.

Bacteriophage ecology in environmental biotechnology processes.

Science.gov (United States)

Shapiro, Orr H; Kushmaro, Ariel

2011-06-01

Heterotrophic bacteria are an integral part of any environmental biotechnology process (EBP). Therefore, factors controlling bacterial abundance, activity, and community composition are central to the understanding of such processes. Among these factors, top-down control by bacteriophage predation has so far received very limited attention. With over 10(8) particles per ml, phage appear to be the most numerous biological entities in EBP. Phage populations in EBP appear to be highly dynamic and to correlate with the population dynamics of their hosts and genomic evidence suggests bacteria evolve to avoid phage predation. Clearly, there is much to learn regarding bacteriophage in EBP before we can truly understand the microbial ecology of these globally important systems. Copyright © 2011 Elsevier Ltd.

Infusing Authentic Inquiry into Biotechnology

Hanegan, Nikki L.; Bigler, Amber

2009-10-01

Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced

Cell biology and biotechnology research for exploration of the Moon and Mars

Science.gov (United States)

Pellis, N.; North, R.

Health risks generated by human long exposure to radiation, microgravity, and unknown factors in the planetary environment are the major unresolved issues for human space exploration. A complete characterization of human and other biological systems adaptation processes to long-duration space missions is necessary for the development of countermeasures. The utilization of cell and engineered tissue cultures in space research and exploration complements research in human, animal, and plant subjects. We can bring a small number of humans, animals, or plants to the ISS, Moon, and Mars. However, we can investigate millions of their cells during these missions. Furthermore, many experiments can not be performed on humans, e.g. radiation exposure, cardiac muscle. Cells from critical tissues and tissue constructs per se are excellent subjects for experiments that address underlying mechanisms important to countermeasures. The development of cell tissue engineered for replacement, implantation of biomaterial to induce tissue regeneration (e.g. absorbable collagen matrix for guiding tissue regeneration in periodontal surgery), and immunoisolation (e.g. biopolymer coating on transplanted tissues to ward off immunological rejection) are good examples of cell research and biotechnology applications. NASA Cell Biology and Biotechnology research include Bone/Muscle and Cardiovascular cell culture and tissue engineering; Environmental Health and Life Support Systems; Immune System; Radiation; Gravity Thresholds ; and Advanced Biotechnology Development to increase the understanding of animal and plant cell adaptive behavior when exposed to space, and to advance technologies that facilitates exploration. Cell systems can be used to investigate processes related to food, microbial proliferation, waste management, biofilms and biomaterials. The NASA Cell Science Program has the advantage of conducting research in microgravity based on significantly small resources, and the ability to

Reengineering the retail/ambulatory pharmacy for provision of biotechnology pharmaceutical services.

Science.gov (United States)

Schneider, P J

1998-07-01

Biotechnology products offer both problems and opportunities for pharmacists. On one hand, they are expensive to purchase and keep on inventory. Typical compensation for outpatient prescriptions does not offset the cost of maintaining the inventory, or providing the education and training that patients often need to use biotechnology products properly. On the other hand, there are issues related to proper storage, preparation, and administration for which pharmacists are well prepared to address. Pharmacists are also convenient, trusted, and provide service at relatively low cost. Examples of special services that pharmacists can provide to improve the use of biotechnology products include patient education, injection clinics, provision of medical supplies, and predrawing syringes for patients. Patients are often sent to many providers for these services, resulting in inconvenience and fragmentation of care. If new compensation methods can be established to support more comprehensive pharmacy services, the use of biotechnology products by patients will improve.

Systems architecture: a new model for sustainability and the built environment using nanotechnology, biotechnology, information technology, and cognitive science with living technology.

Science.gov (United States)

Armstrong, Rachel

2010-01-01

This report details a workshop held at the Bartlett School of Architecture, University College London, to initiate interdisciplinary collaborations for the practice of systems architecture, which is a new model for the generation of sustainable architecture that combines the discipline of the study of the built environment with the scientific study of complexity, or systems science, and adopts the perspective of systems theory. Systems architecture offers new perspectives on the organization of the built environment that enable architects to consider architecture as a series of interconnected networks with embedded links into natural systems. The public workshop brought together architects and scientists working with the convergence of nanotechnology, biotechnology, information technology, and cognitive science and with living technology to investigate the possibility of a new generation of smart materials that are implied by this approach.

Biotechnology software in the digital age: are you winning?

Science.gov (United States)

Scheitz, Cornelia Johanna Franziska; Peck, Lawrence J; Groban, Eli S

2018-01-16

There is a digital revolution taking place and biotechnology companies are slow to adapt. Many pharmaceutical, biotechnology, and industrial bio-production companies believe that software must be developed and maintained in-house and that data are more secure on internal servers than on the cloud. In fact, most companies in this space continue to employ large IT and software teams and acquire computational infrastructure in the form of in-house servers. This is due to a fear of the cloud not sufficiently protecting in-house resources and the belief that their software is valuable IP. Over the next decade, the ability to quickly adapt to changing market conditions, with agile software teams, will quickly become a compelling competitive advantage. Biotechnology companies that do not adopt the new regime may lose on key business metrics such as return on invested capital, revenue, profitability, and eventually market share.

Okundamiya, Michael S.; Emagbetere, Joy O.; Ogujor, Emmanuel A.

2014-07-01

The rising energy costs and carbon footprint of operating mobile telecommunication sites in the emerging world have increased research interests in green technology. The intermittent nature of most green energy sources creates the problem of designing the optimum configuration for a given location. This study presents the design analysis and control strategy for a cost effective and reliable operation of the hybrid green energy system (HGES) for GSM base transceiver station (BTS) sites in isolated regions. The design constrains the generation and distribution of power to reliably satisfy the energy demand while ensuring safe operation of the system. The overall process control applies the genetic algorithm-based technique for optimal techno-economic sizing of system's components. The process simulation utilized meteorological data for 3 locations (Abuja, Benin City and Sokoto) with varying climatic conditions in Nigeria. Simulation results presented for green GSM BTS sites are discussed and compared with existing approaches.

Theobroma cacao-The Food of the Gods, provides the raw material for the multibillion dollar chocolate industry and is also the main source of income for about 6 million smallholders around the world. Additionally, cocoa beans have a number of other nonfood uses in the pharmaceutical and cosmetic industries. Specifically, the potential health benefits of cocoa have received increasing attention as it is rich in polyphenols, particularly flavonoids. At present, the demand for cocoa and cocoa-based products in Asia is growing particularly rapidly and chocolate manufacturers are increasing investment in this region. However, in many Asian countries, cocoa production is hampered due to many reasons including technological, political and socio-economic issues. This review provides an overview of the present status of global cocoa production and recent advances in biotechnological applications for cacao improvement, with special emphasis on genetics/genomics, in vitro embryogenesis and genetic transformation. In addition, in order to obtain an insight into the latest innovations in the commercial sector, a survey was conducted on granted patents relating to T. cacao biotechnology. © 2017 The Authors.

The evolution of biotechnology and its impact on health care.

Science.gov (United States)

Evens, Ronald; Kaitin, Kenneth

2015-02-01

For more than three decades the field of biotechnology has had an extraordinary impact on science, health care, law, the regulatory environment, and business. During this time more than 260 novel biotechnology products were approved for over 230 indications. Global sales of these products exceeded $175 billion in 2013 and have helped sustain a vibrant life sciences sector that includes more than 4,600 biotech companies worldwide. In this article we examine the evolution of biotechnology during the past three decades and the profound impact that it has had on health care through four interrelated and interdependent tracks: innovations in science, government activity, business development, and patient care. The future impact of biotechnology is promising, as long as the public and private sectors continue to foster policies and provide funds that lead to scientific breakthroughs; governments continue to offer incentives for private-sector biotech innovation; industry develops business models for cost-effective research and development; and all stakeholders establish policies to ensure that the therapeutic advances that mitigate or cure medical conditions that currently have inadequate or no available therapies are accessible to the public at a reasonable cost.

Hartley, Sarah; Gillund, Frøydis; van Hove, Lilian; Wickson, Fern

2016-05-01

Agricultural biotechnology continues to generate considerable controversy. We argue that to address this controversy, serious changes to governance are needed. The new wave of genomic tools and products (e.g., CRISPR, gene drives, RNAi, synthetic biology, and genetically modified [GM] insects and fish), provide a particularly useful opportunity to reflect on and revise agricultural biotechnology governance. In response, we present five essential features to advance more socially responsible forms of governance. In presenting these, we hope to stimulate further debate and action towards improved forms of governance, particularly as these new genomic tools and products continue to emerge.

2013-06-01

In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated. The levels of daidzein and genistein were 149.28 μg/g and 364.31 μg/g, respectively. After six weeks experimental period, Food efficiency ratio in the 10 and 20 BTS group was significantly lower than the HF group (PBTS group were significantly lower than the HF group. The levels of alanine aminotransferase, aspartate aminotransferase and thiobarbituric acid reactive substance were significantly lower in the groups that received 10% and 20% BTS than the HF. The activities of SOD and CAT were significantly higher in the 10 and 20 BTS group than the HF group. The activity of XO in the 10 and 20 BTS group was significantly lower than in the HF group by 20% and 23%, respectively. In conclusion, these data suggest that BTS is an effective agent in improving lipid metabolism and antioxidant enzyme system.

Explanations are given on the recent movements in the bio-technology applications. In the United States, gene therapy has been applied to patients having damaged immune system, while in Japan the first outdoor experiment is about to begin this year on gene recombined tomatoes. In the area of the marine bio-technology, researches carried out by the industrial, governmental, and academic sectors combined, led by the Ministry of International Trade and Industry have begun, which include such an attractive subject as finding out new kinds of algae living on carbon dioxide as their special favorite diet to use them to prevent the earth warming-up. On the other hand, the difficulty of bio-business is represented by the fact that venture business groups are absorbed into larger chemical companies. In Japan, the bio-business established in individual regions related to soy bean paste and Shoyu sauce industry is a distinct feature. Deregulations and review on the patent system are in progress in the United States and Germany aiming at strengthening the business competitiveness. Expectation is placed on the bio-technology that it will contribute largely in the future to solving such a critical environmental problem as experienced in the Persian Gulf war. 1 tab.

Pharma Success in Product Development—Does Biotechnology Change the Paradigm in Product Development and Attrition.

Science.gov (United States)

Evens, Ronald P

2016-01-01

The biotechnology segment of the overall biopharma industry has existed for only about 40–45 years, as a driver of new product development. This driving force was initiated with the FDA approval of recombinant human insulin in 1982, originating from the Genentech company. The pharma industry in the early years of 1970s and 1980s engaged with biotechnology companies only to a small extent with their in-licensing of a few recombinant molecules, led by Roche, Eli Lilly, and Johnson and Johnson. However, subsequently and dramatically over the last 25 years, biotechnology has become a primary driver of product and technology innovation and has become a cornerstone in new product development by all biopharma companies. This review demonstrates these evolutionary changes regarding approved products, product pipelines, novelty of the products, FDA approval rates, product sales, financial R&D investments in biotechnology, partnerships, mergers and acquisitions, and patent issues. We now have about 300 biotechnology products approved in USA covering 16 medical disciplines and about 250 indications, with the engagement of 25 pharma companies, along with their biotechnology company innovators and partners. The biotechnology pipeline involves over 1000 molecules in clinical trials, including over 300 molecules associated with the top 10 pharma companies. Product approval rates by the FDA for biotechnology products are over double the rate for drugs. Yes, the R&D paradigm has changed with biotechnology now as one of the major focuses for new product development with novel molecules by the whole biopharma industry.

2016-03-01

Flashing light can enhance photosynthesis and improve the quality and quantity of microalgal biomass, as it can increase the products of interest by magnitudes. Therefore, the integration of flashing light effect into microalgal cultivation systems should be considered. However, microalgae require a balanced mix of the light/dark cycle for higher growth rates, and respond to light intensity differently according to the pigments acquired or lost during the growth. This review highlights recently published results on flashing light effect on microalgae and its applications in biotechnology, as well as the recently developed bioreactors designed to fulfill this effect. It also discusses how this knowledge can be applied in selecting the optimal light frequencies and intensities with specific technical properties for increasing biomass production and/or the yield of the chemicals of interest by microalgae belonging to different genera.

Jelodar, Gholamali; Nazifi, Saeed; Akbari, Abolfazl

2013-09-01

Radio frequency wave (RFW) generated by base transceiver station (BTS) has been reported to make deleterious effects on reproduction, possibly through oxidative stress. This study was conducted to evaluate the effect of RFW generated by BTS on oxidative stress in testis and the prophylactic effect of vitamin C by measuring the antioxidant enzymes activity, including glutathione peroxidase, superoxide dismutase (SOD) and catalase, and malondialdehyde (MDA). Thirty-two adult male Sprague-Dawley rats were randomly divided into four experimental groups and treated daily for 45 days as follows: sham, sham+vitamin C (l-ascorbic acid 200 mg/kg of body weight/day by gavage), RFW (exposed to 900 MHz RFW) 'sham' and 'RFW' animals were given the vehicle, i.e., distilled water and the RFW+vitamin C group (received vitamin C in addition to exposure to RFW). At the end of the experiment, all the rats were sacrificed and their testes were removed and used for measurement of antioxidant enzymes and MDA activity. The results indicate that exposure to RFW in the test group decreased antioxidant enzymes activity and increased MDA compared with the control groups (p < 0.05). In the treated group, vitamin C improved antioxidant enzymes activity and reduced MDA compared with the test group (p < 0.05). It can be concluded that RFW causes oxidative stress in testis and vitamin C improves the antioxidant enzymes activity and decreases MDA.

Guidelines and standards for diagnosis and management of chronic obstructive pulmonary disease (COPD) have been presented by different national and international societies, but the spirometric criteria for COPD differ between guidelines. To estimate prevalence of COPD using the guidelines of the British Thoracic Society (BTS), the European Respiratory Society (ERS), the Global Initiative for Chronic Obstructive Lung Disease (GOLD), and the American Thoracic Society (ATS). Further, to evaluate reported airway symptoms, contacts with health care providers, and physician diagnosis of COPD in relation to the respective criteria, and gender differences. In 1992 a postal questionnaire was sent to a random sample of adults aged 20-69 years, 4,851 (85%) out of 5,681 subjects responded. In 1994-1995 a random sample of the responders, 970 subjects, were invited to a structured interview and a lung function test; 666 (69%) participated. The prevalence of COPD was 7.6, 14.0, 14.1, 12.2 and 34.1% according to BTS, ERS, GOLD, clinical ATS (with symptoms or physician diagnosis), and spirometric ATS criteria, respectively. Prevalent COPD was related to age, smoking habits and family history of obstructive airway disease but not to gender. Physician diagnosis of chronic bronchitis or emphysema was only reported by 16.3, 12.2, 11.0, 23.4 and 8.2% of subjects fulfilling the respective criteria, though a majority reported airway symptoms. The main determinants for prevalent COPD were age, smoking habits and spirometric criteria of COPD. Though a majority reported airway symptoms and contact with health care providers due to respiratory complaints, only a minority was diagnosed as having COPD, indicating a large underdiagnosis.

Hefferon, Kathleen

2010-06-01

Recent advances in agricultural biotechnology have enabled the field of plant biology to move forward in great leaps and bounds. In particular, recent breakthroughs in molecular biology, plant genomics and crop science have brought about a paradigm shift of thought regarding the manner by which plants can be utilized both in agriculture and in medicine. Besides the more well known improvements in agronomic traits of crops such as disease resistance and drought tolerance, plants can now be associated with topics as diverse as biofuel production, phytoremediation, the improvement of nutritional qualities in edible plants, the identification of compounds for medicinal purposes in plants and the use of plants as therapeutic protein production platforms. This diversification of plant science has been accompanied by the great abundance of new patents issued in these fields and, as many of these inventions approach commercial realization, the subsequent increase in agriculturally-based industries. While this review chapter is written primarily for plant scientists who have great interest in the new directions being taken with respect to applications in agricultural biotechnology, those in other disciplines, such as medical researchers, environmental scientists and engineers, may find significant value in reading this article as well. The review attempts to provide an overview of the most recent patents issued for plant biotechnology with respect to both agriculture and medicine. The chapter concludes with the proposal that the combined driving forces of climate change, as well as the ever increasing needs for clean energy and food security will play a pivotal role in leading the direction for applied plant biotechnology research in the future.

Importance of lactobacilli in food and feed biotechnology.

Giraffa, Giorgio; Chanishvili, Nina; Widyastuti, Yantyati

2010-01-01

The genus Lactobacillus is a heterogeneous group of lactic acid bacteria (LAB) with important implications in food fermentation. The ability to colonize a variety of habitats is a direct consequence of the wide metabolic versatility of this group of LAB. Consequently, lactobacilli have been used for decades in food preservation, as starters for dairy products, fermented vegetables, fish and sausages as well as silage inoculants. Lactobacilli have also been proposed as probiotics and microbial cell factories for the production of nutraceuticals. However, a wide range of applications of lactobacilli in food biotechnology remains potential, whereas a number of important strains still need to be discovered and characterized. This article provides an overview of the taxonomy of lactobacilli and describes four of the most significant case studies on the application of this group of LAB in food and feed biotechnology, including their use as probiotics, dairy starters, silage inoculants, and microbial cell factories. The importance of access to and exchange of biological material within and between different strain collections as a crucial step in expanding the range of different biotechnological applications of lactobacilli is also emphasized.

Workshop Summary for Maintaining Innovation and Security in Biotechnology: Lessons Learned from Nuclear, Chemical, and Informational Technologies

Energy Technology Data Exchange (ETDEWEB)

Althouse, Paris [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)

2017-10-11

In the fast-paced field of biotechnology where innovation has such far-reaching impacts on human health and the environment, dealing with the implications of possible illicit activities, accidents or unintended research consequences with potential detrimental societal impacts tends to remain in the background. While controls may be inevitable for the biotech industry, workshop attendees agreed that the way in which controls are implemented will play a major role in the agility and innovation of the biotechnology industry. There is little desire to slow down the pace of the gains while dealing with the security issues that arise. As was seen from the brief examinations of the Nuclear, Chemical, and Information Technology sectors explored in this workshop, establishing a regulatory regime needs to be a partnership between the public, corporate interests, scientists, and the government. Regulation is often written to combat perceived risk rather than actual risk—the public’s perceptions (occasionally even fictional portrayals) can spur regulatory efforts. This leads to the need for a thorough and continuing assessment of the risks posed by modern biotechnology. Inadequate or minimal risk assessment might expedite development in the short term but has potential negative long-term security and economic consequences. Industry and the technical community also often have a large role in setting regulatory policy, especially when well-crafted incentives are incorporated into the regulations. Such incentives might actually lead to enhanced innovation while poorly designed incentives can actually reduce safety and security. Any regulations should be as agile and flexible as the technology they regulate and when applied to biotechnologies they will need a new framework for thinking and implementing. The new framework should consider biotechnology as a technology and not simply a science since it is an extremely complex and adaptive system. This suggests the need to invest

Sugar cane is a major source of food and fuel worldwide. Biotechnology has the potential to improve economically-important traits in sugar cane as well as diversify sugar cane beyond traditional applications such as sucrose production. High levels of transgene expression are key to the success of improving crops through biotechnology. Here we describe new molecular tools that both expand and improve gene expression capabilities in sugar cane. We have identified promoters that can be used to drive high levels of gene expression in the leaf and stem of transgenic sugar cane. One of these promoters, derived from the Cestrum yellow leaf curling virus, drives levels of constitutive transgene expression that are significantly higher than those achieved by the historical benchmark maize polyubiquitin-1 (Zm-Ubi1) promoter. A second promoter, the maize phosphonenolpyruvate carboxylate promoter, was found to be a strong, leaf-preferred promoter that enables levels of expression comparable to Zm-Ubi1 in this organ. Transgene expression was increased approximately 50-fold by gene modification, which included optimising the codon usage of the coding sequence to better suit sugar cane. We also describe a novel dual transcriptional enhancer that increased gene expression from different promoters, boosting expression from Zm-Ubi1 over eightfold. These molecular tools will be extremely valuable for the improvement of sugar cane through biotechnology.

Dynamic Externalities, Universities and Social Capital Formation in the EU Biotechnology Industry

Directory of Open Access Journals (Sweden)

Malgorzata RUNIEWICZ-WARDYN

2017-03-01

Full Text Available The paper investigates the role of dynamic externalities, university-industry linkages and role of social networking in the biotechnology industry in the European Union (EU. Universities act as platforms for local knowledge spillovers and university-industry cluster development in the biotechnology field. The R&D activities at universities contribute to successful business innovations. However, the relationship between the universities and the local innovation capabilities is much more complex and therefore requires more in-depth analysis. The following study derives from the knowledge of the new economic geography, endogenous growth theory, biotechnology, as well as theories of social capital and social networks. The quantitative research elaborates contemporary literature and databases to find channels of interdependence between local university-based knowledge flows, social capital, and biotechnology cluster performance. The results of the study show that the biotechnology industry relies very much on university-business R&D partnerships and research mobility (e.g. pharmaceutical firms that performed basic research in close cooperation with academia produced more patents. In addition, social networking and informal contacts seem to be a more important for the diffusion of knowledge, especially at the beginning of R&D process, as they allow for building credibility between potential partners.

2014-01-01

Full Text Available The biotechnology activities development demands an intense academic and scientific basis, a productive sector capable of transforming academic research in scientific products and services, and the creation of an institutional environment to promote the sector’s development. Moreover, many biotechnology companies establish formal partnerships with Universities (by technological incubator to expand innovative capacity coming into the market. The importance of biotechnology for developing countries is perceived by its ability to promote national development based on knowledge and innovation. In Brazil, the government establishes technological incubators to accelerate the company consolidation. In this way, it is important to study the relationship between the actors involved. In this context, this article aims to analyze the relationship between a technological incubator and a biotech company. To do so, the qualitative approach was adopted to reach the objective. Interviews with incubator’s employees of a Brazilian University and biotechnology company’s managers were conducted. The results show that the company-incubator interaction promoted projects approval which were able to support new researches development and to purchase production equipment. Incubated companies have higher chances of survival in the market from the interaction with University, through the technological incubator. The relationship between the incubator and the biotech company is considered a fundamental condition for biotechnology activities development.

An increasing number of biotechnology projects are being brought to commercialization using conventional structured finance sources, which have traditionally only been available to proven technologies and primary industries. Attracting and securing competitive cost financing from mainstream lenders, however, will require the sponsor of a new technology or process to undergo a greater level of due diligence. The specific areas and intensity of investigation, which are typically required by lenders in order to secure long-term financing for biotechnology-based manufacturing systems, is reviewed. The processes for evaluating the adequacy of prior laboratory testing and pilot plant demonstrations is discussed. Particular emphasis is given to scale-up considerations and the ability of the proposed facility design to accommodate significant modifications, in the event that scale-up problems are encountered.

Science education has been discussed in some segments of the society and, international organizations have encouraged nations to invest in this strategic area. In this context, education in bioethics and biosafety explores a rich content on prevention, standards and ethical principles which serve to guide the paths track by biotechnology. The recovery of bioethics and biosafety, as part of an educational policy scientific, effective and consistent, can stimulate the formation of individuals with a scientific and citizen awareness, in a position to participate on ethical and technological issues produced by biotechnology.

Measuring transferring similarity via local information

Recommender systems have developed along with the web science, and how to measure the similarity between users is crucial for processing collaborative filtering recommendation. Many efficient models have been proposed (i.g., the Pearson coefficient) to measure the direct correlation. However, the direct correlation measures are greatly affected by the sparsity of dataset. In other words, the direct correlation measures would present an inauthentic similarity if two users have a very few commonly selected objects. Transferring similarity overcomes this drawback by considering their common neighbors (i.e., the intermediates). Yet, the transferring similarity also has its drawback since it can only provide the interval of similarity. To break the limitations, we propose the Belief Transferring Similarity (BTS) model. The contributions of BTS model are: (1) BTS model addresses the issue of the sparsity of dataset by considering the high-order similarity. (2) BTS model transforms uncertain interval to a certain state based on fuzzy systems theory. (3) BTS model is able to combine the transferring similarity of different intermediates using information fusion method. Finally, we compare BTS models with nine different link prediction methods in nine different networks, and we also illustrate the convergence property and efficiency of the BTS model.

Latest FAO figures indicate that an estimated 925 million people are undernourished in 2010, representing almost 16% of the population in developing countries. Looking to the future, there are also major challenges ahead from the rapidly changing socio-economic environment (increasing world population and urbanisation, and dietary changes) and climate change. Promoting agriculture in developing countries is the key to achieving food security, and it is essential to act in four ways: to increase investment in agriculture, broaden access to food, improve governance of global trade, and increase productivity while conserving natural resources. To enable the fourth action, the suite of technological options for farmers should be as broad as possible, including agricultural biotechnologies. Agricultural biotechnologies represent a broad range of technologies used in food and agriculture for the genetic improvement of plant varieties and animal populations, characterisation and conservation of genetic resources, diagnosis of plant or animal diseases and other purposes. Discussions about agricultural biotechnology have been dominated by the continuing controversy surrounding genetic modification and its resulting products, genetically modified organisms (GMOs). The polarised debate has led to non-GMO biotechnologies being overshadowed, often hindering their development and application. Extensive documentation from the FAO international technical conference on Agricultural Biotechnologies in Developing Countries (ABDC-10), that took place in Guadalajara, Mexico, on 1-4 March 2010, gave a very good overview of the many ways that different agricultural biotechnologies are being used to increase productivity and conserve natural resources in the crop, livestock, fishery, forestry and agro-industry sectors in developing countries. The conference brought together about 300 policy-makers, scientists and representatives of intergovernmental and international non

Mannans of different structure and composition are renewable bioresources that can be widely found as components of lignocellulosic biomass in softwood and agricultural wastes, as non-starch reserve polysaccharides in endosperms and vacuoles of a wide variety of plants, as well as a major component of yeast cell walls. Enzymatic hydrolysis of mannans using mannanases is essential in the pre-treatment step during the production of second-generation biofuels and for the production of potentially health-promoting manno-oligosaccharides (MOS). In addition, mannan-degrading enzymes can be employed in various biotechnological applications, such as cleansing and food industries. In this review, fundamental knowledge of mannan structures, sources and functions will be summarized. An update on various aspects of mannan-degrading enzymes as well as the current status of their production, and a critical analysis of the potential application of MOS in food and feed industries will be given. Finally, emerging areas of research on mannan biotechnology will be highlighted.
