  • Introduction: Colorectal cancers are in the top of the cancer-related causes of death in the world and lymph node metastasis is accepted as the primary prognostic factor. In this study, correlations of FGF19 staining pattern with local invasion and lymph node metastasis in a series of colorectal cancers were investigated. Methods: This studyincluded 81 colorectal cancer patients who underwent surgery in our hospital with no evidence of preoperative radiological distant metastasis. Routine pathological examination of the resection material was performed in order to identify vascular, perineural and serosal infiltration, regional lymph node metastasis and the degree of differentiation. Tumor tissue samples were stained with an immunohistochemistry method for FGF 19 evaluation and the staining pattern was statistically compared with the above mentioned characteristics of the tumors. Results: The patient population consisted of 47 females and 34 males with a median age of 70 years. In 40 patients regional lymph nodes were positive and 51%, 32% and 38% had serosal, perineural and vascular invasion. While 64 cases were moderately-differentiated, 11 cases were well-differentiated and 6 poorlydifferentiated, there was no association with FGF 19 staining, including intensity. Conclusion: No evidence of significant statistically correlation was found between FGF 19 staining pattern and serosal, perineural, vascular invasion, lymph node involvement and degree of differentiation.

  • Fabry disease is an X-linked disease caused by deficiency of the lysosomal enzyme alpha-galactosidase A. Affected males present anhydrosis, acroparesthesia and angiokeratoma, and subsequently cardiac, cerebral and renal complications are followed. Females and atypical variants show heterogeneous clinical symptoms. In 2001, two recombinant enzymes were approved for Fabry disease: agalsidase alpha and agalsidase beta. Since the introduction of enzyme replacement therapy (ERT), the number of long-term follow-up studies has been reported. Long-term ERT showed effectiveness on renal function in patients with chronic kidney disease, decrease or stabilization of left ventricular mass, and improvement of pain and quality of life. However, there were limited effects on cerebrovascular events and their mortality. Current literatures on the clinical effect of ERT have reported limited datain adult patients who have already advanced disease. Therefore, further study for pre-symptomatic patients and atypical variants is needed to verify the impact of ERT. This review summarized recent progresses in ERT and limitations of long-term effect of ERT in patients with Fabry disease.

  • Insect cell cultures have become important tools in the production of biological substances for use in a variety of research, human and veterinary medicine, and pest control applications. These applications often require the introduction of foreign DNA into the cells and have generally used methods originally developed for use with human and other mammalian cell cultures. While these methods can be successfully employed, they are often less efficient with insect cells and frequently involve complex procedures or require specialized equipment. Even when they do work, they may require substantial modification because of differences in the culture medium or growth patterns of insect cells. In this study, We have optimized transfection conditions of Sf9 cell line using insect expression vector pIZT/V5-His which expresses green fluorescent protein effectively. Human stem cell factor (hSCF) is a glycoprotein that plays a key role in hematopoiesis acting both as a positive and negative regulator, often in synergy with other cytokines. It also plays a key role in mast cell development, gametogenesis, and melanogenesis. It can exist in membrane-bound form and in proteolytically released soluble form. As determined by an enzyme-linked immunosorbent assay performed, hSCF level in supernatant averaged 995ng/ml. The human hSCF was partially purified by immunoaffinity chromatography and analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting. The results show that the hSCF has N-linked carbohydrate and corresponds to the soluble form, at or about 223 amino acids in length. The findings suggest functional importance for soluble hSCF in cells.

  • The introduction of osseointegrated dental implants in dentistry brought about a new era in everyday dental practice. For the past 50 years, prosthetic restoration with implant-supported prosthesis has developed into a viable and predictable treatment option. Alongside the increasing use of dental implants is the occurrence of many complications during implant placement (surgery), in the mechanical or prosthetic problem, and in the biological aspect. In particular, abutment or screw fracture as one of the mechanical complications can put the dentist in a tight spot in a clinical situation. It is hard to remove the fractured abutment and screw to restore it properly. Therefore, it is very important that clinicians consider possible complications in advance and make an appropriate treatment plan. We discuss cases of abutment fracture and mechanical/prosthetic complications together with the causes and solutions.

  • The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

  • A review of dairy development and crossbreeding programmes in Malaysia since 1953 is undertaken, based on the relevant literature and the writer's experience. The need for higher domestic milk production and the role of crossbreeding in the realization of this objective is explained. A retrospective evaluation is made of the past crossbreeding programmes and of the decision to use temperate dairy breeds for the purpose. Current dairy development under the 'New Economic Policy' of the Malaysian government and the major problems connected with the importation of high-milk producing animals are discussed. To overcome existing constraints, future strategies for crossbreeding and dairy development, based on long-term objectives, are proposed. It is concluded that crossbreeding will only be useful if the introduction of high yielding dairy animals is combined with an improvement of existing husbandry systems.

  • The disease known as cerebral cavernous malformations mostly occurs in the central nervous system, and their typical histological presentations are multiple lumen formation and vascular leakage at the brain capillary level, resulting in disruption of the blood-brain barrier. These abnormalities result in severe neurological symptoms such as seizures, focal neurological deficits and hemorrhagic strokes. CCM research has identified 'loss of function' mutations of three ccm genes responsible for the disease and also complex regulation of multiple signaling pathways including the WNT/β-catenin pathway, TGF-β and Notch signaling by the ccm genes. Although CCM research is a relatively new and small scientific field, as CCM research has the potential to regulate systemic blood vessel permeability and angiogenesis including that of the blood-brain barrier, this field is growing rapidly. In this review, I will provide a brief overview of CCM pathogenesis and function of ccm genes based on recent progress in CCM research.

  • Leriche syndrome ia a common entity which causes ischemia of the lower extremities. Since the introduction of aortic resection and homograft replacement by Oudot in 1951, reconstructive procedures to restore distal blood flow by either endarterectomy or, later, with prosthetic graft have become standardized. Recently we experienced a case of Leriche syndrome. A 50 year-old male patient admitted with intermittent claudication, impotence, and symmetrical atrophy at lower extremities. Aortogram revealed complete obstruction at infrarenal abdominal aorta and Doppler sonogram revealed only minimal blood flow at left femoral artery.Successful surgical treatment was accomplished with endarterectomy at proximal left renal artery and a bypass from abdominal aorta at the level of both renal arteries to both external iliac arteries with bifurcated Gore-tex vascular graft. After bypass operation, we did palpate with arterial pulse at both popliteal artery.He was recovered without complication.

  • With recent developments in medical technology and the introduction of various types of lasers, the role of fiberoptic laryngeal laser surgery (FLS) in laryngology has been significantly expanded. FLS are typically performed under local anesthesia, and patients may return to normal activities immediately after the procedure. This corresponds to the current trend of minimally invasive surgery and may limit unnecessary general anesthesia, reduce medical costs, and increase patient compliances. Main indications of FLS procedure were vocal polyp, recurrent respiratory papillomatosis, vocal fold granuloma and vocal fold dysplasia. In this review, we discuss practical tips and unique value of FLS.
