    Through its participation in the South African Customs Union (SACU), South Africa has been involved in negotiations with the United States government on the finalization of a free trade agreement (FTA). Although the US-SACU negotiations eventually ground to a halt, they are more than likely to be reinstated some time soon, and the farreaching implications they portend will have to be confronted afresh. The concern of this contribution is the effect of the US insistence on stronger intellectual property protection for pharmaceutical patents in these bilateral agreements, the resultant impact on the prices of medicines for life-threatening conditions such as HIV/AIDS and related opportunistic diseases. This paper explores some critical issues related to FTAs, examines some of the pressure impacting on the negotiations, reviews the trends around the protection of pharmaceutical patents in some recently concluded agreements, and considers their implications for SACU countries

    Learning from experience: the art and science of clinical law

    Clinical law is a teaching discipline in terms of which students learn the skills, ethics and values necessary for the practice of law. Its mission is accomplished through the practical involvement of students in legal work, whether it is through simulated exercises or representing actual clients in their legal problems. Throughout this process, they are guided by teachers or supervisors who are practising lawyers within the law school. What is unique to this discipline is the employment of teaching methodologies which are experientially-based and geared towards problem solving, rather than ‘academic’ in nature. This contribution looks at some recent developments with regard to the regulation of the legal profession and suggests that clinical law is set to assume an even greater significance with the prospect that the period of vocational training is likely to be reduced, in terms of the draft Legal Practice Bill. Furthermore, the contribution argues that such an approach is a more effective form of teaching and learning, and that its methodologies should be integrated into other teaching disciplines. It also explores a model for implementing the notions expressed in this piece. Finally, based on the experiences of South African law clinics, it argues that clinical law can be delivered effectively even in resource-strapped situations

    This paper explores the role played by international legal treaties, conventions and agreements that are binding on South Africa, in promoting the public’s access to medicines. In greater detail the impact that the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) of 1994, the Convention on Biological Diversity of 1992, and the United States of America’s Bahy-Dole Act of 1980 have had in the development of South Africa intellectual property (IP) law is examined. In addition, a question regarding whether such international legal instruments have positively impacted the public’s access to medicines is considered. The paper concludes that compliance with international IP law rules is not a silver bullet that will solve South Africa’s challenges relating to access to medicines. The protection of the public’s right to access to medicines in South Africa is strongly dependent on the government’s political will of ensuring that IP law is implemented to serve public good and public and private pharmaceutical patent holders are held accountable regarding the socially-responsible utilization of their IP

    An analysis of the temperature dependence of force, during steady shortening at different velocities, in (mammalian) fast muscle fibres

    We examined, over a wide range of temperatures (10–35°C), the isometric tension and tension during ramp shortening at different velocities (0.2–4 L0/s) in tetanized intact fibre bundles from a rat fast (flexor hallucis brevis) muscle; fibre length (L0) was 2.2 mm and sarcomere length ~2.5 μm. During a ramp shortening, the tension change showed an initial inflection of small amplitude (P1), followed by a larger exponential decline towards an approximate steady level; the tension continued to decline slowly afterwards and the approximate steady tension at a given velocity was estimated as the tension (P2) at the point of intersection between two linear slopes, as previously described (Roots et al. 2007). At a given temperature, the tension P2 declined to a lower level and at a faster rate (from an exponential curve fit) as the shortening velocity was increased; the temperature sensitivity of the rate of tension decline during ramp shortening at different velocities was low (Q10 0.9–1.5). The isometric tension and the P2 tension at a given shortening velocity increased with warming so that the relation between tension and (reciprocal) temperature was sigmoidal in both. In isometric muscle, the temperature T0.5 for half-maximal tension was ~10°C, activation enthalpy change (∆H) was ~100 kJ mol−1 and entropy change (∆S) ~350 J mol−1 K−1. In shortening, these were increased with increase of velocity so that at a shortening velocity (~4 L0/s) producing maximal power at 35°C, T0.5 was ~28°C, ∆H was ~200 kJ mol−1 and ∆S ~ 700 J mol−1 K−1; the same trends were seen in the tension data from isotonic release experiments on intact muscle and in ramp shortening experiments on maximally Ca-activated skinned fibres. In general, our findings show that the sigmoidal relation between force and temperature can be extended from isometric to shortening muscle; the implications of the findings are discussed in relation to the crossbridge cycle. The data indicate that the endothermic, entropy driven process that underlies crossbridge force generation in isometric muscle (Zhao and Kawai 1994; Davis, 1998) is even more pronounced in shortening muscle, i.e. when doing external work

    A 'snip' in time: what is the best age to circumcise?

    <p>Abstract</p> <p>Background</p> <p>Circumcision is a common procedure, but regional and societal attitudes differ on whether there is a need for a male to be circumcised and, if so, at what age. This is an important issue for many parents, but also pediatricians, other doctors, policy makers, public health authorities, medical bodies, and males themselves.</p> <p>Discussion</p> <p>We show here that infancy is an optimal time for clinical circumcision because an infant's low mobility facilitates the use of local anesthesia, sutures are not required, healing is quick, cosmetic outcome is usually excellent, costs are minimal, and complications are uncommon. The benefits of infant circumcision include prevention of urinary tract infections (a cause of renal scarring), reduction in risk of inflammatory foreskin conditions such as balanoposthitis, foreskin injuries, phimosis and paraphimosis. When the boy later becomes sexually active he has substantial protection against risk of HIV and other viral sexually transmitted infections such as genital herpes and oncogenic human papillomavirus, as well as penile cancer. The risk of cervical cancer in his female partner(s) is also reduced. Circumcision in adolescence or adulthood may evoke a fear of pain, penile damage or reduced sexual pleasure, even though unfounded. Time off work or school will be needed, cost is much greater, as are risks of complications, healing is slower, and stitches or tissue glue must be used.</p> <p>Summary</p> <p>Infant circumcision is safe, simple, convenient and cost-effective. The available evidence strongly supports infancy as the optimal time for circumcision.</p

    Transparency in Medicines Regulatory Affairs Reclaiming Missed Opportunities

    Get PDF
    Transparency is a salutary value in our constitutional architecture. It has also been described as a necessary element in promoting accountability in the regulatory aspects of essential medicines. Despite its several incarnations, the Medicines and Related Substances Act (Medicines Act) retains a provision headed 'Preservation of secrecy' (section 34). This contributionseeks to evaluate section 34 in the context of transparency and ascertain whether it is in conflict with other legislation pertaining to the promotion of access to information and, in particular, whether it is consistent with the Constitution of the Republic of South Africa

    A South African study comparing the effectiveness of computer-based learning materials and face-to-face teaching

    This paper compares the effectiveness of in-house developed computer-based learning (CBL) materials with face-to-face teaching. Two groups of higher education students were randomly assigned to complete tutorial work in one highly structured topic of introductory accounting using either CBL materials (treatment group) or face-to-face teaching (control group). The effectiveness of both approaches was measured according to the students’ performance in a class test, in relation to their prior accounting knowledge and gender. The results showed that the students with no prior accounting knowledge who completed the CBL materials achieved a significantly higher test mark than the face-to-face teaching group. However, there was no significant difference in the marks of the students with prior accounting knowledge, and there was no difference on the basis of gender. The results of this South African study correspond to results in existing literature in other countries, and contribute to the overall knowledge of the effectiveness of CBL materials with respect to prior accounting knowledge and gender.Accounting education, Computer-based learning (CBL), Face-to-face teaching, Gender, Prior accounting experience, Student performance
