Abstract
BACKGROUND Lopinavir/ritonavir 'pellets' were recently tentatively approved for licensing. We describe their acceptability for infants and children up to 48 weeks. METHODS CHAPAS-2 was a randomized, two-period crossover trial comparing syrup and pellets in HIV-infected infants (n=19, group A, aged 3-<12 months) and children (n=26, group B, 1-<4 years) and tablets and pellets in older children (n=32, group C, 4-<13 years) from two clinics ('JCRC', 'PIDC') in Uganda. At week 8, all groups chose which formulation to continue. Acceptability data were collected at weeks 0, 4, 8, 12 and 48. RESULTS For groups A and B overall, the proportion preferring pellets increased between week 0 and week 12 and decreased at week 48 (group A 37%, 72%, 44%; group B 12%, 64% and 36%, respectively), although there were marked differences between clinics. For group C, pellets were progressively less preferred to tablets over time: 41%, 19% and 13% at weeks 0, 12 and 48, respectively. During follow-up unpleasant taste was similarly reported among young children taking pellets and syrups (37%/43% group A; 29%/26% group B), whereas among older children, pellets tasted worse than tablets (40%/2%). No participants reported problems with storage/transportation for pellets (0%/0%) unlike syrups (23%/13%). CONCLUSIONS For children <4 years, pellets were more acceptable at week 12 but not week 48. Clinic differences could reflect bias among health-care workers for different formulations. Pellets taste similar to syrup, are easier to store and transport than syrup and represent an alternative formulation for young children unable to swallow tablets; improvements in taste and support for health-care workers may help sustain acceptability.

Abstract
OBJECTIVE The present study aims at evaluating, in a rat model of cartilage defect, the potential of various polymers as filling and repair biomaterials. The macroscopic and histological observations are compared to biochemical parameters in order to appreciate the pertinence of the latter as suitable criteria in tissue engineering. METHODS A hydrogel, consisting of hyaluronic acid (HA), covalently substituted by hydrophobic alkyl chains (HA12, HA18) and an alginate sponge, alone (Asp) or combined with HA (AHAsp) or combined with HA and chondrocytes (HYBsp) were evaluated. Cartilage lesions were drilled in femoral trochlea of rats. The analyses were performed on trochlea as well as on patella and condyles. RESULTS Repairs achieved with hydrogels had a similar macroscopic appearance than those afforded by AHAsp and HYBsp. Best macroscopic and histological scores were obtained with HA18 and HYBsp in comparison with alginate group (P< 0.01 and P< 0.02 respectively). Biochemical evaluations confirmed the presence of similar amounts of proteoglycans in the repaired zones and in the controls, though with different DeltadiC4S/DeltadiC6S ratios and enhanced HA levels. CONCLUSIONS Hydrogels or sponges proved to be colonized by cells synthesizing a matrix with a high HA content. The matrix obtained eventually turns hyaline and takes over the scaffold. The addition of HA and/or chondrocytes to Asp significantly improves the macroscopic and histological scores (P< 0.05 and P< 0.02 respectively). However, biochemical parameters are significantly different of those evaluated in native cartilage. The present study shows that only biochemical parameters allow to discriminate between various biomaterials in tissue engineering and are essential informations which should be taken into account in addition to macroscopic and histological observations.

Abstract
Studies are underway to design biosystems containing embedded chondrocytes to fill osteochondral defects and to produce a tissue close to native cartilage. In the present report, a new alginate three-dimensional support for chondrocyte culture is described. A sodium alginate solution, with or without hyaluronic acid (HA), was freeze-dried to obtain large-porosity sponges. This formulation was compared with a hydrogel of the same composition. In the sponge formulation, macroscopic and microscopic studies demonstrated the formation of a macroporous network (average pore size, 174 microm) associated with a microporous one (average pore size, 250 nm). Histological and biochemical studies showed that, when loaded with HA, the sponge provides an adapted environment for proteoglycan and collagen synthesis by chondrocytes. Cytoskeleton organization was studied by three-dimensional fluorescence microscopy (CellScan EPR). Chondrocytes exhibit a marked spherical shape with a nonoriented and sparse actin microfilament network. Type II collagen was detected in both types of sponges (with or without HA) using immunohistochemistry. In conclusion, the sponge formulation affords new perspectives with respect to the in vitro production of "artificial" cartilage. Furthermore, the presence of hyaluronate within the alginate sponge mimics a functional environment, suitable for the production by embedded chondrocytes of an extracellular matrix.

Abstract
This article addresses the increasing need within urban communities for effective, culturally relevant HIV prevention programs. The recruitment efforts of a family-based prevention program aimed at promoting health and preventing HIV risk exposure in urban, African American fourth and fifth grade children living in a community with high rates of HIV infection is detailed. The program, referred to as the CHAMP (Chicago HIV Prevention and Adolescent Mental Health Project) Family Program, is overseen by a collaborative partnership of community parents, school staff, and university-based researchers (Paikoff & McKay, 1995). The recruitment strategies developed as a result of this community-research collaboration are described. Preliminary results of the project's efforts to reach out to families within the targeted, inner-city community are presented.
