Asymmetric Synthesis of Cyclopentene Compounds Containing All-Carbon Quaternary Stereocenters by (3 + 2) Cycloaddition and Its Application in the Formal Synthesis of ()-(-)-Puraquinonic Acid.

A highly stereoselective (3 + 2) cycloaddition for the asymmetric synthesis of versatile cyclopentene compounds containing all-carbon quaternary stereocenters was developed. The phosphine-catalyzed reactions of alkynoates with α-alkylated electron-deficient alkenes bearing Oppolzer's camphorsultam showed high to excellent diastereoselectivities and perfect regioselectivities. The usefulness of this reaction was demonstrated in the concise formal synthesis of ()-(-)-puraquinonic acid.

[HIV Disclosure to the Child/Adolescent in Central and West Francophone Africa].

We report the attitudes and practices of health care workers involved in the disclosure process to adolescents living with HIV (ALHIV) in a network including West and Central African French-speaking countries, and the experiences of young living with HIV (YLHIV). During a three-day workshop in Abidjan, Côte d'Ivoire, caregivers (doctors, psychologists, social workers) from 19 pediatric HIV treatment sites shared their practices and difficulties, and four YPLHIV their own disclosure experience. Thirty five participants from eight West/Central African countries (Benin, Burkina Faso, Ivory Coast, Cameroon, Mali, Democratic Republic of Congo, Senegal, Togo) contributed: 14 doctors, eight psychologists, six counselors, three social workers.

Taking empowerment into account: the response of community-based organisations to the HIV care needs of men who have sex with men in West Africa (CohMSM ANRS 12324 - Expertise France).

Empowerment is an ongoing process through which individuals and communities appropriate power and acquire the capability to function autonomously. Research on empowerment in men who have sex with men (MSM) is lacking in community-based contexts. We investigated the relationship between willingness to be empowered and HIV care needs in West African MSM accessing community-based organisations' (CBO) services.

MDCT features of strangulated ileus due to an appendix epiploica of the sigmoid colon: four cases and a review of the literature.

Purpose: The aim of this study was to investigate the multidetector computed tomography (MDCT) features of strangulated ileus caused by epiploic appendix of the sigmoid colon.

Methods: We retrospectively evaluated MDCT images of four patients who underwent surgery in our hospital between 2011 and 2014. Patients were aged from 66 to 79 years, and two were female.

[Acceptability of HIV testing provided to infants in pediatric services in Cote d'Ivoire, meanings for pediatric diagnostic coverage].

Problem: HIV testing in children had rarely been a central concern for researchers. When pediatric tracking retained the attention, it was more to inform on the diagnosis tools' performances rather than the fact the pediatric test can be accepted or refused. This article highlights the parents' reasons which explain why pediatric HIV test is accepted or refused.

Clinical outcome of microscopic lumbar spinous process-splitting laminectomy: clinical article.

Object: The authors sought to quantify the clinical outcome of microscopic lumbar spinous process-splitting laminectomy in patients with lumbar spinal stenosis (LSS). They performed a microscopic laminectomy in which the spinous process is split longitudinally into 2 halves. For single-level decompression, they inserted a tubular retractor between the split process.

Universal HIV screening at postnatal points of care: which public health approach for early infant diagnosis in Côte d'Ivoire?

Background: Universal HIV pediatric screening offered at postnatal points of care (PPOC) is an entry point for early infant diagnosis (EID). We assessed the parents' acceptability of this approach in Abidjan, Côte d'Ivoire.

Methods: In this cross-sectional study, trained counselors offered systematic HIV screening to all children aged 6-26 weeks attending PPOC in three community health centers with existing access to HAART during 2008, as well as their parents/caregivers.

This study evaluates HIV infant diagnosis on DBS using Biocentric HIV1-DNA and HIV1-RNA assays, in field conditions in Côte d'Ivoire. Paediatric screening was offered to children≤3 years in clinical sites in Côte d'Ivoire in 2008. For each HIV-infected child, two non-infected children were included and blood samples were collected.

Mirror observation of finger action enhances activity in anterior intraparietal sulcus: a functional magnetic resonance imaging study.

Mirror therapy can be used to promote recovery from paralysis in patients with post-stroke hemiplegia, There are a lot of reports that mirror-image observation of the unilateral moving hand enhanced the excitability of the primary motor area (M1) ipsilateral to the moving hand in healthy subjects. but the neural mechanisms underlying its therapeutic effects are currently unclear. To investigate this issue, we used functional magnetic resonance imaging to measure activity in brain regions related to visual information processing during mirror image movement observation.

Attitudes and practices of health care workers toward routine HIV testing of infants in Côte d'Ivoire: the PEDI-TEST ANRS 12165 Project.

Objective: We assessed attitudes and practices of health care workers (HCWs) toward HIV counselling and testing (CT) routinely offered to infants in health facilities in Abidjan, Côte d'Ivoire.

Methods: We performed a cross-sectional survey inquiring on systematic HIV CT offered to children aged 6-26 weeks attending postnatal care for either immunization or pediatric care and to their parents in 4 community health centres rolling-out access to antiretroviral therapy. Data were collected using standardized anonymous self-questionnaires directed to all HCWs involved.

Clinical outcome of microendoscopic posterior decompression for spinal stenosis associated with degenerative spondylolisthesis--minimum 2-year outcome of 37 patients.

A clear consensus for the optimal surgical treatment for spinal stenosis associated with degenerative spondylolisthesis (DS) has not appeared. In general, decompression and fusion are recommended. However, the symptoms of spinal stenosis are the main complaints in almost all patients with DS, and whether or not routine concomitant fusion is necessary in the surgical treatment for DS is still discussed controversially.

Effect of modified constraint-induced movement therapy on lower extremity hemiplegia due to a higher-motor area lesion.

Background: Modified CIT (mCIT) was performed in a stroke patient with a lesion in the left medial frontal region including the supplementary motor area (SMA), which is part of the higher-motor area, and whose primary symptom was motor ignition difficulty observed at the start of voluntary movement of the right leg.

Case Study: mCIT was performed from awakening to bedtime (not including bath time) with his non-affected limb fixed with a knee splint while he was in the hospital ward. Two days (the total time he wore the appliance was 19.

Surgical complications of microendoscopic procedures for lumbar spinal stenosis.

Microendoscopic discectomy (MED) is one of the minimally invasive endoscopic procedures for treating lumbar disc herniation. We have applied MED techniques to posterior decompression procedures for treating lumbar spinal stenosis (LSS). In the present study, we examined the surgical complications in 114 consecutive patients surgically treated with MED procedures for LSS.

Objectives: The purpose of this study was to report the long-term outcome of HPLL in the thoracic spine.

Short-term results of microendoscopic posterior decompression for lumbar spinal stenosis. Technical note.

Object: The authors applied the technique of microendoscopic discectomy to posterior decompression procedures for lumbar spinal stenosis. The purpose of this study was to determine the feasibility of using an endoscopic technique to treat lumbar spinal stenosis and to evaluate the clinical and radiographic results of microendoscopic posterior decompression (MEPD).

Methods: Microendoscopic posterior decompression, which involves a unilateral endoscopic approach for bilateral decompression, was performed in 47 patients.

Spontaneous dissection of the superior mesenteric artery in four cases treated with anticoagulation therapy.

Reports of spontaneous dissection of the superior mesenteric artery are rare. Diagnosis in the acute stage has been considered difficult, but we encountered four cases from November 1998 to November 2001. All four cases were diagnosed using abdominal CT scanning in the acute stage and could be treated conservatively.

Extraosseous accumulation of bone scanning agents in malignant brain tumors: comparison to semi-quantitative evaluation with 99mTc SPECT/201Tl SPECT and histological findings.

Although 201Tl chloride (Tl) SPECT has been used in the differential diagnosis between recurrence of malignant brain tumor and necrosis after treatment, it is not generally recognized as a definite modality to distinguish them. We conducted a preliminary study using Tl SPECT and 99mTc-MDP or 99mTc-HMDP (Tc) SPECT because it has been said that extraosseous accumulation was caused by calcium deposits in necrotic tissues. In our study, for the purposes of clarifying the mechanism of extraosseous uptake and the correlation between extraosseous accumulation of bone-scanning agent and tumor viability in malignant brain tumors, we compared whether Tc uptake was correlated with the histopathological findings and further performed semi-quantitative evaluation between Tc SPECT and Tl SPECT.

Inhibition of metastatic brain tumor growth by intramuscular administration of the endostatin gene.

The cancer patients suffering from brain metastases are basically incurable. The conventional tumoricidal strategies frequently cause severe side effects instead of life prolongation of such patients. On the other hand, antiangiogenic therapy seems to be a promising strategy to avoid such unfavorable effects.
