Inappropriate DNA methylation of tumour suppressor genes can affect their expression and function, as such, has been a promising target for anti-cancer therapy. In gynaecological malignancy, ovarian cancer the highest associated rate mortality. This study investigated in vitro cytotoxicity four sesquiterpene lactones (SLs), including dehydroleucodine (Deh), alantolactone (Ala), costunolide (Cos...

Trevor disease or dysplasia epiphysealis hemimelica (DEH) is an extremely rare condition with incidence of about 1:1,000,000. Male to female ratio of reporting case is 3:1, and usually diagnosed between two and eight years old. It usually affects the medial portion of the joint, but lateral involvement is not uncommon. Hip-joint was affected in less than 4% of existing cases in the literature. ...

We all remember the empty faces of students seated in rows, intermittently taking notes, and trying to retain disjointed facts. This old lecture style seems as antiquated as a 19th century clockwork mechanism; familiar and charming, but erratic and no longer adequate. The orderly structure of industrial age mechanisms and the repetitiveness of the assembly line are giving way to the all-at-once...

The development of technology coupled with the idea of global village is driving a trend that is advancing development of under developed nations through transfer of technology. To date, the transfer has mostly been in the form of finished products such as equipment being sold to developing nations. The designs for the pieces of equipment were initially inspired by technological needs in temper...

Atom transfer radical polymerization (ATRP) was used as a versatile route to well-defined poly(diethylhexyl-p-phenylenevinylene-b-styrene) (PPV-b-PS) semiconducting block copolymers. For this purpose, original conjugated macroinitiators were synthesized from DEH-PPV and further used for the copolymerization reaction. The microphase-separated morphologies obtained with the semiconducting PPV-bPS...

Cyber security is an important aspect of National Security and the safekeeping of a Nation's constituency and resources. In South Africa, the focus on cyber security is especially prominent since many geographical regions are incorporated into the global village in an attempt to bridge the digital divide. This article reflects on current research and implementation done in South Africa with reg...

Direct electrical heating (DEH) is a well-established method for preventing hydrate formation inside subsea oil transfer pipelines. However, poor efficiency and high reactive power requirement of the existing line-frequency DEH systems have necessitated high-frequency processing along with compensation. To meet these design objectives, dc–ac converter using an LCCL resonant tank presented in th...

The advent of various wireless technologies have revolutionized the communication infrastructure and consequently changed the entire world into a global village. Use of wireless technology has also been made for transmission of electric power wirelessly. It increases the portability of power systems and integrates the communication technologies and electric power to the same platform. This pape...
