  • 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.

  • Localized or radiating pain in the arm and shoulder joint may result after faulty alignment causing compression or tension on nerves, blood vessels, or supporting soft tissues. The critical site of faulty alignment is the quadrangular space in the axilla bounded by the teres major, teres minor, long head of triceps, and humerus. The axillary nerve emerges through this space to supply the deltoid and teres minor. The activity of the trigger point on teres minor compressing the axillary nerve causes pain to develop through the area of sensory distribution of cutaneous branch of the axillary nerve. Relieving compression on the axillary nerve and suprascapular nerve is the key point to relieving the pain. Spasm of the supraspinatus and infraspinatus compressing the suprascapular nerve caused pain to develop in the shoulder joint and scapular area. We treated those patients experiencing such pain with local anesthetic infiltration or I-R laser stimulation on the identified trigger points.

  • Headache after epidural block is the most frequent result of an unintentional dural puncture. This form of headache is usually caused by cerebrospinal fluid leakage through the dural puncture site. Another proposed cause of postdural puncture headache is the unintentional injection of air into the subarachnoid space. We experienced a case of severe headache with a patient after lumbar epidural block and discovered air in the intracranial subarachnoid space(pneumocephalus) with the aid of brain computerized tomography.

  • Wheat germ agglutinin (WGA) pectin, which binds to human melanoma cell line, was conjugated with Praecoxin A using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide as a cross-linking agent. Physical mixture (PM) of WGA and Praecoxin A was also prepared by using a non-specific binding property of Praecoxin A to WGA. The WGA:Praecoxin A ratio in the conjugate and PM was approximately 1:18 and 1:20, respectively. The results of hemagglutination assay and enzyme-linked lectin assay indicated that the conjugate and PM maintained the lectin-like properties of the WGA. The binding ratio of conjugate was about 70% during 4-24 hr, but the most of Praecoxin A was released within 24 hr in the case of PM. These results lead to the conclusion that the conjugate is potentially useful for the formulation of injection that requires targeting for melanoma as well as sustained release at the site.

  • A retrograde tracer, WGA-apo-HRP-gold, was injected into midline thalamic nuclei and subsequently orexin-A immunostaining was performed on the tuberal region of the hypothalamus in order to investigate orexinergic projections to the midline thalamus. Injection site was targeted within one specific region, i.e., paraventricular, centromedian, rhomboid, reuniens, or intermediodorsal nucleus, but it proved to be either one or a combination of these thalamic nuclei. The distribution of WG/orexin-double-labeled neurons exhibited a general pattern in that the majority of labeled cells were observed within the ventral portion of the lateral hypothalamus as well as the perifornical nucleus (PeF). A small number of double-labeled cells were also observed at the dorsomedial nucleus, the area dorsal to the PeF, dorsal portion of the lateral hypothalamus, and the posterior hypothalamus. These orexin-immunoreactive neurons might have wake-related influences over a variety of functions related with midline thalamic nuclei, which include autonomic control, associative cortical functions, and limbic regulation.

  • During esophagectomy and esophagogastrostomy, the prediction of anastomotic leakage relies on the operating surgeon's tactile or visual diagnosis. Therefore, anastomotic leaks are relatively unpredictable, and new intraoperative evaluation methods or tools are essential. A fluorescence imaging system enables visualization over a wide region of interest, and provides intuitive information on perfusion intraoperatively. Surgeons can choose the best anastomotic site of the gastric tube based on fluorescence images in real time during surgery. This technology provides better surgical outcomes when used with an optimal injection dose and timing of indocyanine green.

  • In a diesel engine the phenomenon of spray impaction on a chamber wall has been taken as an undesirable matter because of the deposition of fuel on the surfaces, and the subsequent slow evaporation and mixing with air resulting in unburned hydrocarbons. Therefore many researches have concentrated on avoiding fuel impingement on surfaces. On the contrary done a number of studies using spray wall impactions in a positive way, which makes the droplets smaller, changes the direction into free spaces far from the wall and also improves mixing with air. In this paper the size of the impaction site prepared for the injection spray which is raised from the bottom in the piston bowl center is analysed as both simulative and experimental manner.

  • DWP401, a recombinant human epidermal growth factor, was subcutaneously administered to ICR mice at the dose levels of 0, 0.04, 0.2 and 1.0 mg/kg/day (15rats/sex/group) in order to evaluate the subchronic toxicity. General observations, examinations for food and water consumption, ophthalmoscopy and urinalysis were carried out during the study. For the complete gross and microscopic examinations, 10 mice/ sex/group were sacrificed at the ends of the dosing period, and the remaining animals were sacrificed with a 5 week recovery period. Examinations for hematology and blood biochemistry were also carried out at the time of recovery period. Based on the results, it was thought that the target tissue or organs were mesothelial cell, injection site, spleen, adrenal gland, ovary and transitional epithelial cell of urinary tract, and no observed toxic level of DWP401 was 0.04 mg/kg while definite toxic dose level might be 0.2 mg/kg.

  • Endometrial cancer (EC) represents the most common gynecological neoplasm in developed countries. Surgery is the mainstay of treatment for EC. Although EC is characterized by a high prevalence several features regarding its management are still unclear. In particular the execution of lymphadenectomy is controversial. The recent introduction of sentinel node mapping represents the mid-way between the execution and omission of node dissection in EC patients. In the present review we discuss the emerging role of sentinel node mapping in EC. In addition, we discussed how type of tracers utilized and site of injection impacted on sentinel node detection rates. Future perspective regarding EC management are also discussed.
