Abstract
Type 1 and type 2 diabetes mellitus is a serious and lifelong condition commonly characterised by abnormally elevated blood glucose levels due to a failure in insulin production or a decrease in insulin sensitivity and function. Over the years, prevalence of diabetes has increased globally and it is classified as one of the leading cause of high mortality and morbidity rate. Furthermore, diabetes confers a huge economic burden due to its management costs as well as its complications are skyrocketing. The conventional medications in diabetes treatment focusing on insulin secretion and insulin sensitisation cause unwanted side effects to patients and lead to incompliance as well as treatment failure. Besides insulin and oral hypoglycaemic agents, other treatments such as gene therapy and induced β-cells regeneration have not been widely introduced to manage diabetes. Therefore, this review aims to deliver an overview of the current conventional medications in diabetes, discovery of newer pharmacological drugs and gene therapy as a potential intervention of diabetes in the future.

The role of pazopanib on tumour angiogenesis and in the management of cancers: A review. Biomed Pharmacother 2017; 96:768-781.

Abstract
Pazopanib is a relatively new compound to be introduced into the chemotherapy field. It is thought to have decent anti-angiogenic properties, which gives an additional hope for the treatment of certain types of cancers. A systematic review solely discussing about pazopanib and its anti-angiogenic effect is yet to be published to date, despite several relevant clinical trials being conducted over the recent years. In this review, we aim to investigate the mechanism of pazopanib's anti-angiogenic effect and its effectiveness in treating several cancers. We have included, in this study, findings from electronically searchable data from randomized clinical trials, clinical studies, cohort studies and other relevant articles. A total of 352 studies were included in this review. From the studies, the effect of pazopanib in various cancers or models was observed and recorded. Study quality is indefinite, with a few decent quality articles. The most elaborately studied cancers include renal cell carcinoma, solid tumors, advanced solid tumors, soft tissue sarcoma, breast cancer and gynecological cancers. In addition, several less commonly studied cancers are included in the studies as well. Pazopanib had demonstrated its anti-angiogenic effect based on favorable results observed in cancers, which are caused by angiogenesis-related mechanisms, such as renal cell carcinoma, solid tumors, advanced solid tumors and soft tissue sarcoma. This review was conducted to study, analyze and review the anti-angiogenic properties of pazopanib in various cancers. The results obtained can provide a decent reference when considering treatment options for angiogenesis-related malignancies. Furthermore, the definite observations of the anti-angiogenic effects of pazopanib could provide newer insights leading to the future development of drugs of the same mechanism with increased efficiency and reduced adverse effects.

Abstract
The purpose of this study was to investigate the impact of hyaluronidase (HAase) on lymphedema using an acute mouse tail lymphedema model. Six-week-old mice served to produce acute lymphedema and were then either treated with HAase injection or used as operative controls. An additional group of unmanipulated normal mice was used for comparison. Tail volumes were measured for 23 days and histological changes examined. Western blot analysis was conducted to quantify lymphatic vessel endothelial hyaluronan receptor (LYVE)-1, tumor necrosis factor (TNF)-alpha, transforming growth factor (TGF)-beta1, podoplanin, CD 44, and vascular endothelial growth factor receptor3 (VEGFR3) expression levels. The operative control group showed an increase in thickness of the dermis and subdermis, microlymphatic dilatation, and an increase in neutrophils. In contrast, the HAase treated group exhibited alleviation of inflammation evidenced by a decline in microlymphatic dilatation and neutrophils and an overall increase in microlymphatic vessels. Western blot analysis demonstrated that TNF-alpha and TGF-beta1 expression declined but CD44 expression increased in the HAase treated group. Levels of LYVE1, podoplanin, and VEGFR3 also increased significantly in the HAase group. Our results indicate that HAase treatment in the acute mouse tail model reduced lymphedema volume possibly through degradation of HA trafficking, which reduced inflammation and fibrosis in tissues and stimulated lymphangiogenesis.

Abstract
This study presents an unusual case of primary lymphedema of the upper extremity in a healthy 28-year-old woman. The onset of swelling of the left upper extremity was observed at birth, but was not accurately diagnosed until the patient visited our department. Diagnostic assessment included evaluating the patient's history and laboratory and radiological data, which were all normal except for the swollen upper extremity and the lymphoscintigraphy findings. The patient was diagnosed as suffering from primary lymphedema of her left arm. Complete decongestive therapy was done and her swelling mildly improved.

Abstract
Progression to cancer in Barrett's esophageal columnar metaplasia is classically heralded by the presence of epithelial dysplasia. Differentiation of reactive epithelial atypia and mild dysplasia from severe dysplasia, however, may often be difficult especially with limited biopsy material. We performed DNA content analysis of 11 cases of Barrett's esophagus showing variable reactive atypia, 24 cases of Barrett's with low- and high-grade dysplasia, and 30 cases of Barrett's with invasive adenocarcinoma (BCA) using Feulgen-stained paraffin sections and the CAS 200 image analyzer. The mean DNA index of the uniformly diploid BE was 1.06. The 1.26 mean DNA index for the low-grade Barrett's esophagus with dysplasia, 1.62 for high grade, and 1.88 DI for BCA were significantly greater than for variable reactive atypia (P < 0.004) but not different from each other. Six BCA cases (20%) were diploid; 24 cases (80%) were aneuploid. Mean survival of diploid BCA at 20.4 mo was nearly double the survival of 10.6 mo for aneuploid BCA. However, this difference was not statistically significant (P < 0.21) and survival at 3 yr was identical for all BCA cases. Tumor grade, stage, and lymph node status did not significantly correlate with ploidy pattern. Thus, although DNA analysis does not seem to predict ultimate outcome in BCA, aneuploidy and high DNA index are associated with Barrett's esophagus with dysplasia and BCA and may be of significant value in the differentiation from variable reactive atypia in small biopsies.
