Skin microrelief alters progressively with age. Wrinkles do not result from these changes but are superimposed upon them. Wrinkles result from structural changes in the epidermis, dermis and hypodermis. Four types of wrinkles can be recognized. Type 1 wrinkles are atrophic. Type 2 wrinkles are elastotic. Type 3 wrinkles are expressional. Type 4 wrinkles are gravitational. Each type of wrinkle is characterized by distinct microanatomical changes and each type of wrinkle develops in specific skin regions. Each is likely to respond differently to treatment. Skin microrelief and skin folds can be identified on histological examination. By contrast, only minimal dermal changes are found beneath permanent or reducible wrinkles compared with immediately adjacent skin. A series of objective and non-invasive methods is available to quantify the severity of wrinkling. [less ▲]

This paper proposes a framework for sketches analysis that could be useful for sketch-based interfaces development, in the particular context of preliminary activity-centred design. We will first describe our previous works on sketch-based support tools for the preliminary design phases and the context of these researches. The next chapter declares the concrete objectives of our approach, then the methodology of sketches analysis we propose is presented with a concrete example, and finally the last section is dedicated to the expected results and specifications of a sketch-based support tool that would follow our framework.

In this paper, we adopt a differential-geometry viewpoint to tackle the problem of learning a distance online. As this prob- lem can be cast into the estimation of a fixed-rank positive semidefinite (PSD) matrix, we develop algorithms that ex- ploits the rich geometry structure of the set of fixed-rank PSD matrices. We propose a method which separately updates the subspace of the matrix and its projection onto that subspace. A proper weighting of the two iterations enables to continu- ously interpolate between the problem of learning a subspace and learning a distance when the subspace is fixed. [less ▲]

For the first time, the status of cavy culture in the Democratic Republic of the Congo (DRC) is reviewed with emphasis on Sud-Kivu province. Cavy culture, as discussed in this paper, is the raising, production and utilization of the domestic cavy (i.e., Guinea pig, Cavia porcellus) for consumption. Many sources were used in the review, but published scientific research literature is extremely scarce. Nevertheless, it can be estimated that more than 2 million cavies are kept in DRC, contributing significantly to nutrition security, especially animal protein, and income generation of some hundreds of thousands of poor rural and urban households. The largest cavy populations are in the Kivu provinces, which is probably partly due to the inclusion of cavies in ‘rehabilitation kits’ of humanitarian NGOs and in the agricultural portfolio of development agencies who seek to address the challenges of widespread hunger and malnutrition in the area. The review covers the history of cavy culture in Sud-Kivu since colonial times based on oral tradition; it describes the current ‘cavy status’ in the country and identifies research and capacity building needs. We suggest that cavy culture in DRC is likely to become more widespread and important due to the activities of a new project on ‘Harnessing husbandry of domestic cavy for alternative and rapid access to food and income in Cameroon and the eastern Democratic Republic of the Congo’. Given the dimension, cavies should be included in livestock census as well as research and development agenda, honoring their role in the livelihoods of less endowed people, especially women.

Arachidonic acid (AA) metabolites are key mediators involved in the pathogenesis of numerous cardiovascular, pulmonary, inflammatory, and thromboembolic diseases. One of these bioactive metabolites of particular importance is thromboxane A(2) (TXA(2)). It is produced by the action of thromboxane synthase on the prostaglandin endoperoxide H-2 (PGH(2)) which results from the enzymatic transformation of AA by the cyclooxygenases. It is a potent inducer of platelet aggregation, vasoconstriction and bronchoconstriction, and has been involved in a series of major pathophysiological conditions. Therefore, TXA(2) receptor antagonists, thromboxane synthase inhibitors and drugs combining both properties have been developed by different laboratories since the early 1980s. Several Compounds have been launched on the market and others are tinder clinical evaluation. In the first part of this review. we will describe the physiological properties of TXA(2), thromboxane synthase and thromboxane receptors. The second part is dedicated to a description of each class of thromboxane modulators with the advantages and disadvantages they offer. In the third part. we aim to describe recent studies performed with the most interesting thromboxane modulators in major pathologies: myocardial infarction and thrombosis, atherosclerosis, diabetes, pulmonary embolism, septic shock.. preeclampsia, and asthma. Each pathology will be systematically reviewed. Finally, in the last part we will highlight the latest perspectives in drug design of thromboxane modulators and in their future therapeutic applications such as cancer, metastasis and angiogenesis.

The technology of reproduction progressed considerably during the last decade, leading to a certain availability of in vitro methods for fertilisation, oocyte maturation and embryo culture. The most spectacular manipulations are cloning and transgenesis. This review focuses on the early appearance of germinal cell precursors and the long-standing fate of gametes in mammals. The evident complexity and long-term programming of events in gametes and early embryos explain part of the difficulties encountered during the development of in vitro and in vivo methods such as multiple Ovulation and embryo transfer (MOET), oestrus synchronisation, ovulation induction, superovulation, in vitro maturation and fertilisation, cryopreservation, transgenesis, nuclear transfer and cloning) and the occurrence of unexpected alterations of development, e.g. embryonic or fetal mortality, large-weight newborn syndrome and other dysregulations ill imprinting or DNA transmission.

During the last decade, the technology of reproduction progressed considerably leading to a certain availability of in vitro methods for fertilization, maturation of the oocyte and culture system for the embryos. The most spectacular manipulations are cloning and transgenesis… This review focuses on the early appearance of the germinal cells precursors and the longstanding destiny of the gametes in mammals. The evident complexity and long-term programmation of events in gametes and early embryo explain the difficulties to succeed in in-vitro methods and the occurrence of unexpected alterations of development, e.g. embryonic or fetal mortalities, large weight newborn syndrome and other dys-regulations in imprinting or DNA transmission. “Studying and teaching the reproductive physiology in mammals, we sometimes imagine that a newborn animal survived two pregnancies: the first one would be a high risk pregnancy that represents the oocyte development and survival inside the follicle with a tetraploïd genome and the zona pellucida & cumulus cells as placenta-like structures. Around the first birth (ovulation), oocytes (individuals) accept in vitro conditions for maturation, fertilization and culture. Afterwards, a second pregnancy will be necessary in the mother or in the recipient uterus; a low risk pregnancy depending on the oocyte competence acquisition and on the conditions or length of exposure in vitro. “ [less ▲]
