Automation plays an important role in many instruments. In the past, the technology is not mastered by domestic manufacturers. So many large instruments in industry are imported from abroad and that leads to high costs. What's more, some instruments are complicated to operate and are not suitable for technicians. In th... |
Purpose of reviewThe microorganisms that colonise our bodies, the commensal ‘microbiota’, respond to changes in our behaviour and environment, and can also profoundly affect our health. We can now investigate these organisms with unprecedented depth and precision, revealing that they may contribute to the pathogenesis ... |
Of the three classes of true phosphoinositide (PI) 3-kinases, the class II subdivision, which consists of three isoforms, PI3K-C2alpha, PI3K-C2beta and PI3K-C2gamma, is the least well understood. There are a number of reasons for this. This class of PI 3-kinase was identified exclusively by PCR and homology cloning app... |
In many software development projects, people tend to repeat same mistakes due to lack of shared knowledge from past experiences. Generally, it is very difficult to manually find out valuable phenomena from huge data. Invisible context, which cannot be known directly from software documents or formal reports, is an imp... |
Since Kawasaki disease was first reported 20 years ago, many investigations about cardiac complications and treatment have been carried out. However, etiology still remains unknown. Although many studies focused on coronary artery lesions (CAL) have been reported, there have been only a few reports of pathological stud... |
We propose that neoplasms of lymphoid tissue arise, not as a result of immunosuppression, but as a consequence of immunostimulation. Evidence from experimental models and clinical findings is marshalled in favor of this idea. Unchecked immunostimulation may lead to activation of latent oncogenic viruses, which in turn ... |
The water question goes beyond the local and the Arab level to the regional and the international one. It is believed that the next conflict between the Arab states and Israel will take place for one of them to control the limited natural water resources in the region. Water scarcity leads to a big pressure on food pro... |
TuMV particles were purified from artificially infected leaves of Brassica juneaen, and TuMV-RNA was extracted from these particles. The virus thus purified showed typical nucleoprotein absorbent peak under UV light scanning, and the ratio of A260/A280 was 1.21. The RNA thus prepared showed typical ribonucleic acid abs... |
Emerging database applications require the use of new indexing structures beyond B-trees and R-trees. Examples are the k-D tree, the trie, the quadtree, and their variants. They are often proposed as supporting structures in data mining, GIS, and CAD/CAM applications. A common feature of all these indexes is that they ... |
Abstract- Visually impaired is a general term to describe the condition of a person experiencing disability totheir sense of sight. Due to the disability, the process of orientation and mobility of the people with visuallyimpairment is inhibited. Therefore they try to increase their sensitivity of other senses like sen... |
Professor Sheikh and colleagues (June 2004 JRSM1) favoured legislation that would compel cyclists to wear helmets. They conceded that the ethical argument was somewhat stronger for children than for adults. Subsequent correspondents questioned the evidence on helmet efficacy and argued that legislation would have negat... |
As a non-invasive drug delivery method, atomizing drug delivery method has become an investigating hotspot in the fields ofpharmacy and medical instruments, and has widely potential applications in the future. It is used for delivery of antibiotic, antiviral drug, anti hypertension drug, angina drug, and other drugs in... |
The Cancer Research Campaign has said that it will no longer provide research support to any faculty or comparable unit that receives funding from the tobacco industry. |
The charity's new draft code of practice aims to ensure that future scientific grants are not tainted with tobacco money. The code was drawn up after the announcement last year that British American Tobacco was to …Influence of activating and inhibitory killer immunoglobulin-like receptors on predisposition to recurren... |
BACKGROUND |
Understanding of the immune events and mechanisms occurring at the feto-maternal interface is likely to help in understanding the ability of the fetus to survive within the maternal body. Evidence supporting extensive roles of natural killer cells during pregnancy gives rise to a possibility that these NK cells can be ... |
METHODS |
Gene-specific PCR amplification (PCR-SSP) was used to determine the individual KIR genotypes in women experiencing RM and controls. |
RESULTS |
A higher prevalence of activating KIR genes was seen in patients than in controls. Among women experiencing RM, the BB genotypes were more prevalent (P < 0.0001, OR = 4.4, 95% CI = 2.89-6.69) compared with controls. |
CONCLUSIONS |
Our results indicate that the balance between inhibitory and activating receptor-mediated signals present in natural killer cells is inclined toward a more activating state that may contribute to pregnancy loss.The influence of intraabdominal hypertension on the central nervous system: current insights and clinical rec... |
INTRODUCTION |
Intra-abdominal hypertension (IAH) and abdominal compartment syndrome are a common occurrence in ICU patients. The deleterious effects of IAH on organ function are well known and increasingly appreciated in recent years, especially where renal and respiratory function are concerned. |
METHODS |
This review will focus on the available literature from the last years.A Medline and PubMed search was performed in order to find an answer to the question "What is the impact of increased IAP on neurologic function in the critically ill?" |
RESULTS |
The amount of data on the influence of IAH on the central nervous system is more scarce, but several animal and human studies have demonstrated a clear correlation between intra-abdominal pressure (IAP) and intracranial pressure (ICP). This correlation is probably due to transmission of the increased IAP to the thorax ... |
CONCLUSIONS |
A close relationship between IAP and ICP has been observed in several animal and human studies. The clinical impact of this association is dependent on the baseline ICP and the compensatory reserve of the patient. Some studies have reported good results in treating refractory ICH by abdominal decompression in patients ... |

BACKGROUND/AIMS |
Acute pancreatitis (AP) is one of the most common gastrointestinal causes of hospital admission in Qatar. The aim of the present study was to investigate the epidemiological features and demographic characteristics of patients with AP and to estimate the annual incidence rates of this disease among adult inhabitants in... |
MATERIALS AND METHODS |
This retrospective study was conducted using the data collected by reviewing records of patients with AP admitted to the medical and surgical wards of Hamad GeneralHospital and Alkhor Hospital, Qatar from January 2007 to December 2012. Diagnosis of AP was based on abdominal pain suggestive of AP, serum lipase and/or am... |
RESULTS |
A total of 382 AP events were reported in 334 patients. There were 250 (75%) males and 84 (25%) females. The mean age (±SD) of the patients was 56.8±18.7 years. Gallstone disease (40.6%) was the highest cause of AP, followed by alcohol consumption (28.5%) and idiopathic AP (20.7%). The mean annual incidence rate of AP ... |
CONCLUSION |
The annual incidence rate of AP is relatively low in Qatar and tends to behave similar to many European countries in etiology, which can be explained by population structure. Gallstone and alcohol consumption are the main causes, and idiopathic AP is responsible for more cases than expected.Children of Aztlán: The Mexi... |
The Mexican heritage in art, music, dance, architecture, economics, and politics antedates that of the Christian era by at least four millenniums. The cultural distinctiveness of the five Southwestern states (Arizona, California, Colorado, New Mexico, and Texas) where 85 percent of the Mexican Americans in the United S... |
In this paper, a new scheme based on state feedback control concept is presented for robust control of bidirectional interlink power converters (BILPCs) in hybrid microgrids (HMGs). The studied grid-connected HMG contains one dc and one ac microgrid, interconnected by BILPCs. To consider uncertainties, the nonlinear un... |
CONTEXT |
Traditionally, acromegaly is viewed as a disease resulting from GH hypersecretion from an autonomous pituitary somatotropinoma. |
OBJECTIVE |
To test the hypothesis that GH secretion in acromegaly is still subjected to normal hypothalamic control, we studied the daily rhythmicity of GH secretion in normal controls and patients with newly diagnosed, untreated acromegaly. |
DESIGN AND SETTING |
This was an observational inpatient study in the General Clinical Research Center at the University of Michigan. |
PATIENTS OR OTHER PARTICIPANTS |
One hundred four normal controls and 67 acromegalic patients were included in the study. |
INTERVENTION |
The intervention consisted of frequent blood sampling over 24 hours. |
