Objective : The potassium disturbance associated with thiopental continuous infusion in neurosurgical patients is well known. However, the effect of propofol continuous infusion on serum potassium levels has not been investigated extensively. Methods : We reviewed the medical records of 60 consecutive patients who received coma therapy or deep sedation for intracranial pressure control using either thiopental or propofol between January 2010 and January 2012. Results : The overall incidence of hypokalemia (K<3.5 mmol/L) was comparable between thiopental and propofol groups (89.2% vs. 82.6%). But, the incidence of moderate to severe hypokalemia (K<3.0 mmol/L) was significantly higher in thiopental group (51.4% vs. 13.0%, p=0.003). The lowest potassium level (2.9 mmol/L vs. 3.2 mmol/L, p=0.020) was lower in thiopental group. The patients in the thiopental group required greater potassium replacement than the propofol group patients (0.08 mmol/kg/h vs. 0.02 mmol/kg/h, p<0.001). On multivariate analysis, thiopental [odds ratio, 95% confidence interval, 7.31 (1.78-27.81); p=0.005] was associated with moderate to severe hypokalemia during continuous infusion. The incidence of rebound hyperkalemia (K>5.0 mmol/L, 32.4% vs. 4.3%, p=0.010) and the peak potassium concentration (4.8 mmol/L vs. 4.2 mmol/L, p=0.037) after the cessation of therapy were higher in thiopental group. On multivariate analysis, thiopental [8.82 (1.00-77.81); p=0.049] and duration of continuous infusion [1.02 (1.00-1.04); p=0.016] were associated with rebound hyperkalemia once therapy was discontinued. Conclusion : Propofol was less frequently associated with moderate to severe hypokalemia after induction and rebound hyperkalemia following the cessation of continuous infusion than thiopental.

Purpose: To investigate whether the long-term use of a cane induces pain in the unaffected lower limb of stroke patients. Methods: A total of 107 stroke patients with chronic hemiparesis were recruited in this study and classified into two groups; a cane-use group (n=49) and non-cane-use group (n=58). The existence of pain in the unaffected lower limb was assessed on a visual analog scale in the hip, knee, and ankle joint, and the University of Alabama pain behaviors scale (UAB pain behavior scale) used to measure the intensity of pain. In addition, the Motricity Index (MI) was tested in the upper and lower extremities. Results: The proportion of pain in each joint of the lower limb was significantly higher in the cane-use group, compared to the non-cane-use group (p<0.05). In addition, significant differences were observed on the UAB pain behavior scale between the two groups. The lower MI score was significantly lower in the cane-use group, compared with the control group. However, no difference was observed in MI scores of the upper limb between the two groups. Conclusion: These findings reveal that long-term cane usage can induce pain in the unaffected lower limb of stroke patients. We suggest careful consideration when prescribing a cane, depending on functional ability in hemiparetic patients, and recommend continuous evaluation for pain in the affected lower limb.

The promyelocytic leukemia (PML) gene is a gene known to be a tumor suppressor, although recent data suggest that it has a dual function in tumorigenesis. It was initially discovered in acute promyelocytic leukemia (APL) in which a t(15; 17) chromosomal translocation fused it to the retinoic acid receptor alpha ($RAR{\alpha}$). It has been shown to be involved in various types of cancer. It has at least 6 nuclear isoforms and a cytoplasmic type with different characteristics. Its multiple functions in growth inhibition, apoptosis induction, replicative senescence, inhibition of oncogenic transformation, and suppression of migration and angiogenesis have made it a therapeutic target for cancer therapy. However, its dual role in the process of tumorigenesis has made this field challenging. In this review, we discuss PML structure, functions and expression in tumors.

Objectives : The purpose of this study is to examine the preparing methods of the traditional acupuncture needle and to interpret the electromagnetic meaning intervened in them. Methods : The overall manufacturing processes of the acupuncture needles in ancient books were surveyed. And the facts that special functional activities were carried out in common in the preparing processes were detected. The reproduction tests for the detected former functional activities were followed. Results : According to the ancient medical books, the traditional acupuncture needles were treated with the magnet through the preparing processes. The reproduction tests provided the fact that the ferromagnetic iron needles treated with the magnet were enhanced their magnetisms. And major techniques of the ancient supplementation and draining can be interpreted as magnetic or induced electromagnetic actions. Conclusions : Considering the electromagnetic characteristics of human body, the magnet treated ferromagnetic iron needles of ancient era and magnetic or induced electromagnetic interpretable manipulation techniques are the historical evidences of magnetic activities of acupuncture. So modern acupuncture therapy should be understood, studied, and reinterpreted as an electromagnetic viewpoint.

ALA is an essential intermediate in the tetrapyrrole biosynthesis pathway and has applications as a biodegradable herbicide and insecticide as well as medical applications including photodynamic therapy of cancers. For the development of mass production process of ALA it is necessary to on-line monitor some metabolites such as glycine, succinate, LA and ALA. In this work, medium compositions, pH conditions, induction and addition of LA were investigated to increase the production of ALA by recombinant E. coli. A 2-dimensional fluorescence sensor was used to monitor the processe and the fluorescence spectra were correlated with on- and off-line data like ALAS, ALAD, cell mass etc.

Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract and characterized by relapsing and remitting episodes, with progression over time to complications of stricture, fistulas, or abscesses. The etiology is unknown, although the common opinion is that the disease arises from a disordered immune response to the gut contents in genetically predisposed individuals. Infliximab is a mouse-human chimeric antibody against tumor necrosis factor ${\alpha}$, and has proven to be effective in active Crohn's disease for both induction and maintenance therapy. Despite the growing experience with infliximab in Crohn's disease, optimal treatment strategies still need to be determined. The purpose of this review is to summarize the current knowledge on the use of infliximab in Crohn's disease and to discuss the yet-unsolved issues.

An often overlooked issue in the field of adenovirus (Ad)-mediated cancer gene therapy is its limited capacity for effective systemic delivery. Although primary tumors can be treated effectively with intralesional injection of conventional Ad vectors, systemic metastasis is difficult to cure. Systemic administration of conventional naked Ads leads to acute accumulation of Ad particles in the liver, induction of neutralizing antibody, short blood circulation half-life, non-specific biodistribution in undesired organs, and low selective accumulation in the target disease site. Versatile strategies involving the modification of viral surfaces with polymers and nanomaterials have been designed for the purpose of maximizing Ad anti-tumor activity and specificity by systemic administration. Integration of viral and non-viral nanomaterials will substantially advance both fields, creating new concepts in gene therapeutics. This review focuses on current advances in the development of smart Ad hybrid nanocomplexes based on various design-based strategies for optimal Ad systemic administration.
