Abstract
Four strains of Enterobacter sakazakii were inoculated into tryptic soy broth and reconstituted powdered infant formula and exposed to high-pressure processing. Pressures of 200, 400, and 600 MPa were used for each medium for 1 min. E. sakazakii was reduced by more than 6 log (strains A and B) in both media at 600 MPa. Strain B was significantly (P < or = 0.05) more pressure resistant than the other strains, with just more than a 3-log reduction at 600 MPa in both media. The reconstituted infant formula has a significant (P < or = 0.05) protective effect for certain strains and pressures (strain B at 400 MPa and strain D at 400 and 600 MPa). Differences in log reductions between media (milk and broth) were also observed for certain strains and specific pressures (strain B at 400 MPa and strain D at 400 and 600 MPa; P < or = 0.05). This research showed that E. sakazakii, when present in reconstituted powdered infant formula, can be submitted to high-pressure processing (600 MPa for 1 min) and achieve log reductions ranging from 3 to 6.84, depending on the strain.

Abstract
It was recently proved that solitons embedded in the spectrum of linear waves may exist in discrete systems, and explicit solutions for isolated unstable embedded lattice solitons (ELS) of a differential-difference version of a higher-order nonlinear Schrodinger equation were found [Gonzalez-Perez-Sandi, Fujioka, and Malomed, Physica D 197, 86 (2004)]. The discovery of these ELS gives rise to relevant questions such as the following: (1) Are there continuous families of ELS? (2) Can ELS be stable? (3) Is it possible for ELS to move along the lattice? (4) How do ELS interact? The present work addresses these questions by showing that a novel equation (a discrete version of a complex modified Korteweg-de Vries equation that includes next-nearest-neighbor couplings) has a two-parameter continuous family of exact ELS. These solitons can move with arbitrary velocities across the lattice, and the numerical simulations demonstrate that these ELS are completely stable. Moreover, the numerical tests show that these ELS are robust enough to withstand collisions, and the result of a collision is only a shift in the positions of the solitons. The model may apply to the description of a Bose-Einstein condensate with dipole-dipole interactions between the atoms, trapped in a deep optical-lattice potential.

Abstract
The NKG2D-DAP10 receptor complex activates natural killer (NK) cells and costimulates effector T cell subsets upon engagement of ligands that can be conditionally expressed under physiologically harmful conditions such as microbial infections and malignancies. These characteristics have given rise to the widely embraced concept of immunorecognition of "induced or damaged self," complementing the "missing self" paradigm that is represented by MHC class I allotypes and their interactions with inhibitory receptors on NK cells. However, this notion may only be partially sustainable, as various patterns of constitutive tissue distributions have become apparent among members of one NKG2D ligand family. This review summarizes the biological properties of NKG2D and its ligands and discusses the interactions and regulation of these molecules with emphasis of their significance in microbial infections, tumor immunology, and autoimmune disease.

Abstract
In this report, we demonstrate a possible molecular mechanism by which a hydrophilic extract of the leaves of the fern Polypodium leucotomos (Fernblock, PL) blocks ultraviolet (UV)-induced skin photodamage. The extract inhibits UVA and UVB light induced photoisomerization of trans-urocanic acid (t-UCA), a common photoreceptor located in the stratum corneum, and also blocks its photodecomposition in the presence of oxidizing reagents such as H2O2, and titanium dioxide (TiO2). PL protects in vitro human fibroblasts from UV-induced death as well. These results suggest the potential of employing the PL extract as a component of sunscreen moistures in order to prevent photodecomposition of t-UCA, to inhibit UV-induced deleterious effects of TiO2 and to protect skin cells and endogenous molecules directly involved in skin immunosurveillance.

Abstract
The extract of the fern Polypodium leucotomos (PL, Fernblock) is an oral photoprotectant with strong antioxidative properties. Recent studies to determine its chemical composition have shown 4-hydroxycinnamic acid (p-coumaric), 3 methoxy-4-hydroxycinnamic acid (ferulic), 3,4-dihydroxycinnamic acid (caffeic), 3-methoxy-4-hydroxybenzoic acid (vanillic) and 3-caffeoilquinic acid (chlorogenic) to be among its major phenolic components. No conclusive data are available, however, on the H2O2-scavenging capacity of these compounds, or on their absorption and metabolism following their oral intake. In the present work, their antioxidative capacity was assessed by the luminol/H2O2 assay, their absorption studied using Caco-2 cells to resemble the intestinal barrier, and their metabolism investigated using cultured primary rat hepatocytes. The antioxidant capacity of PL components increased in a concentration-dependent manner, with ferulic and caffeic acids the most powerful antioxidants. The apparent permeability results correspond to a human post-oral administration absorption of 70-100% for all tested substances. Coumaric, ferulic and vanillic acids were metabolized by CYP450-dependent mono-oxygenases and partially conjugated to glucuronic acid and sulfate. These phenolic compounds may contribute to the health benefits afforded by this oral photoprotectant.

Abstract
Catheter removal is now the standard recommendation of catheter-related fungemia even when tunneled devices are used. However, in the clinical practice, this procedure is not always without risks. Antibiotic-lock technique can resolve many cases of catheter-related bacteraemia, but cure of catheter-related candidemia by this method has been attempted in very few instances, reviewed in this article. Herein, we report a case of non-complicated Candida glabrata fungemia related to a Hickman catheter used for parenteral nutrition, cured with intraluminal amphotericin B in addition to systemic therapy. This case demonstrates that 'antifungal-lock therapy' can be effectively used in selected cases of catheter-related candidemia.

Abstract
KIR and HLA loci are both highly polymorphic, and some HLA class 1 products bind and trigger cell-surface receptors specified by KIR genes. We examined whether KIR genes act in concert with HLA-B locus to control HIV-1 infection in a sample of Zambian patients. DNA samples from 88 Zambian patients with HIV-1 were examined. Patients were classified as either slow progressors (SP; n = 54) or rapid progressors (RP; n = 34) to AIDS. All were typed for HLA-B and KIR genes. Our results reveal an association between B*57 supertype (B*57s, which includes B*57 and B*58 alleles) and delayed progression to AIDS (p = 0.0007 by pc = 0.015; OR = 5.25). We also observed an increase incidence of Bw4-I80 in patients with slow progression (p = 0.001 by pc = 0.003, OR = 5). This increase was found to be secondary to B*57s. The presence of both KIR3DL1 and B*57S has a significant effect on progression to AIDS (p = 0.0008; OR = 5.61). B*57s genotypes with another HLA-B allele different from those in the trans position, which also had a specificity different to Bw4-I80 (Bw4-T80 or Bw6), was also greater in the SP than in the RP group (p = 0.00003; OR = 10.11). The presence of the inhibitory allele KIR3DL1 in combination with the HLA-B*57s alleles that contain the Bw4-I80 epitope, has a highly protective effect against progression to AIDS in Zambian patients.

Abstract
BACKGROUND Spontaneous supratentorial intracerebral haemorrhages (SSIH) carry high morbidity and mortality rates. At present, the proper role of surgery is not clear and data from the International STICH trial have not clarified this challenging question. On the other hand, few prospective studies have measured long term survival regardless of the treatment and clinical condition of the patient. PATIENTS AND METHODS We prospectively collected data from all SSIH patients (n = 356) admitted at a tertiary reference hospital over a 40-month time period regardless of their clinical condition and treatment received. Among data investigated were preclinical neurological state, GCS on admission, history of systemic hypertension and treatment (surgical or conservative). Clinical factors influencing mortality at 1-year follow-up were analysed statistically by univariable and multivariable methods. FINDINGS We found that patients in the eighth decade were the most frequent. Hypertension was present in 47% of patients. Based on the prehospitalisation modified Rankin Scale, 305 (86%) patients were independent for activities of daily living (ADL). At 12-months follow-up, 91 (46% of alive patients) remained independent for ADL. The surgical rate was 22%. Although it was not a randomised study, we did not find a significantly different mortality rate according to whether the patient was treated surgically or conservatively. Overall, the mortality rate was 44% (157 patients) with a 79% of deaths taking place in the first 30 days after admission. CONCLUSIONS This study underscores the high mortality rate of SSIH, especially so in the first month after admission. Among the subgroup of patients clinically independent before the haemorrhagic stroke, only 29.8% remained independent one year after the event. We did not find any statistically significant difference in mortality according to treatment modality received (surgical vs conservative) although treatment assignment was not randomised. Among other clinical factors, pre-ictal functional status, age, level of consciousness on admission and volume of haemorrhage strongly influence mortality as determined at the 1-year follow-up.

Abstract
Circumscribed palmar hypokeratosis is a recently described condition that consists of a solitary area of depressed skin affecting the palm (or sole). Its histopathological features include a thinned horny layer, a slightly diminished granular cell layer, and intraepidermal vacuolated cells. Prolonged treatment with topical calcipotriol resulted in complete recovery of the affected zone in the case reported here. A second biopsy of the lesion taken at around the fourth year of therapy showed a normalization of the granular layer, a reduction in the intraepidermal vacuolated cells, and a somewhat thicker horny layer. An ultrastructural study carried out at the same time showed a reduction in keratin bundles and keratohyalin granules, and an increase in lipid droplets up to the horny layer. These findings and the therapeutic response to topical calcipotriol support the concept that circumscribed palmar hypokeratosis is a focalized abnormal keratinization defect morphologically expressed at the granular and horny layers.

Abstract
A new formulation for a poly(glycidyl methacrylate-co-ethylendimethacrylate)-based resin with a 11:9 proportion of monomer to crosslinker is developed and amino-functionalized in order to obtain new particulate materials suitable for egg-white protein fractionation. Functionalization is carried out using three different chemical reagents: diethylamine (DEA), DEA-tetrahydrofuran (THF) (1:1), and concentrated ammonia. The ammonia- and DEA-THF-treated polymers are used to fractionate egg-white proteins, in particular lysozyme and ovalbumin, by anion-exchange chromatography in packed column experiments, the latter resin showing better performances. Finally, both supports, working at semipreparative scale and step-gradient elution, separate pure ovalbumin with a yield of 83%.

Abstract
A 57-year-old Caucasian woman with Type 2 diabetes treated for seven years with diet and oral combination hypoglycaemic therapy was referred because of the progressive deterioration of glycaemic control. She was obese (77 kg, BMI = 39.9), hypertensive, hypercholesterolaemic with marked osmotic symptoms (HbA(1c) 12.2%), therefore she was started on insulin (Human Mixtard 30 b.d.) with metformin therapy. Dietary counselling, recommendations to increase physical activity, and supervised self-injection technique with titration of her insulin were also provided. She was routinely followed-up to assess her progress. Two years later, her glycaemic control remained suboptimal. Average HbA(1c) was 10.4% despite an increasingly high dose of insulin (94 units/day) although it improved when metformin was increased to 1 g t.d.s. (HbA(1c) = 9.3%). Her BMI progressively rose from 39.9 to 42.1 (77 to 82.5 kg) despite dietary advice. A trial of orlistat (three months) was commenced, after intensive dietary counselling, that reduced her body weight by 1.5 kg (2% reduction, BMI 41.3). However, her HbA(1c) improved by 0.5% (from 9.3 to 8.8%). Six months after orlistat was stopped her HbA(1c) rose to 10.5% and weight increased to 81.8 kg (BMI 41.8). Despite the orlistat treatment broaching NICE guidelines should it have been continued?

Abstract
OBJECTIVE To analyze the HLA distribution in a population of individuals from Zambia in order to establish a possible relationship between the progression of human immunodeficiency virus (HIV) infection and the development of spondylarthropathy (SpA). METHODS A large epidemiologic analysis of rheumatology patients living in Zambia was performed in order to identify those who had SpA. We selected 64 patients with SpA and found that 54 also had HIV type 1 (HIV-1) infection; only 10 were HIV negative. Additionally, we selected 57 HIV-infected individuals without SpA and 43 healthy controls. Among all of the HIV-1-infected patients, 25 SpA-positive and 24 SpA-negative patients were classified as slow progressors to acquired immunodeficiency syndrome (AIDS), and 8 SpA-positive and 26 SpA-negative patients were classified as rapid progressors. All patients were typed for HLA-B alleles. RESULTS Of the 64 patients with SpA, HIV infection was observed in 54 (84%). The frequency of B*5703 was increased in patients who were SpA positive and HIV positive compared with patients who were SpA negative and HIV positive (P = 0.0002, odds ratio [OR] 8.28). Among patients who were slow progressors to AIDS, this allele was overrepresented in those with SpA compared with those without SpA (corrected P = 0.001, OR 26.25). CONCLUSION HLA-B*5703 seems to be a protective allele against the progression of HIV infection but could influence the increased incidence of SpA observed in this population.

Abstract
The chemical conjugation of bacterial polysaccharide to carrier proteins has proved to be an efficient tool to improve the immunological response against these bacterial antigens. In this study, we characterized the antibody response generated in a non-human primate model against the meningococcal capsular polysaccharide serogroup C (CCPS) conjugated to the P64k protein. Similar to licensed vaccines the CCPS conjugate is able to generate a good memory immune response with antibody titers threefold higher than the free CCPS. Three different ELISA protocols were used to measure the antibody response and the importance of the coating antigen was demonstrated. The ELISA using the derivatized CCPS showed the best results and had a high correlation with the bactericidal activity. The antibodies elicited showed a high protective capacity when assayed in the infant rat protection model.

Abstract
We performed a family study to evaluate a total of 34 extended family members (8 siblings, 23 children and nephews, and 3 grandchildren) of an adult patient with celiac disease (CD), a 58- year-old male with severe neurologic involvement manifested as myoclonias. We found 3 other members affected with CD (a 44-year old sister, a 39-year old niece, and a 26-year old nephew). Two of them were completely asymptomatic and all had hypertransaminasemia. All exhibited a villous atrophy pattern of the duodenal mucosa (1 mild, 1 moderate, 1 severe). Overall family involvement was 11.8% (4/14). We wish to emphasize the need to perform extended family studies when diagnosing a case of CD, since risk is not restricted to only first-degree relatives.
