The functional role of NCAM gene expression in memory formation was studied in the one-trial passive avoidance task in day-old chicks by pretraining injections of one of three different 18-mer end-protected oligonucleotides corresponding to positions 190-, 207-, and 332- of the NCAM Ig1 domain. Twenty-four-hour-old chicks were trained by pecking at a bitter-tasting bead and tested for avoidance...

Betulinic acid (BA), a pentacyclic triterpene, represents a new therapeutic substance that has potential benefits for treating glioblastoma. Recently, new strategies for producing BA derivatives with improved properties have evolved. However, few studies have examined the combination of BA or BA derivatives using radiotherapy. The effects of two BA derivatives, NVX-207 and B10, on cellular and ...

Human papillomaviruses (HPV) are at the origin of many mucosal, benign or malignant skin pathologies. Some so-called high-risk genotypes, especially types 16 and 18, involved in genesis cervical cancer, one most common cancers women. To determine prevalence HPV infections to identify oncogenic genotypes circulating departments Niari Bouenza. A total 207 samples collected between 2019 2020 were ...

BACKGROUND International osteoporosis foundation described severe or established osteoporosis as an osteoporotic individual with a fragility fracture. Orthopaedic surgeons frequently manage fractures, but we believe that large gaps are prevalent in the medical management of osteoporosis after fractures are fixed. AIM The aim of this analysis is to assess the investigations and gaps in the man...

Can a climate-triggered export of old contaminants from the soil alter the lead (Pb) contaminant burden of subarctic lakes? To address this question, we reconstructed the pollution history of three high latitude lakes situated in a region where a recent climatic shift has occurred. Dated sediment records were used as archives of past Pb inputs to the lakes, where the difference in the (206)Pb/(...

INTRODUCTION Among the bacterial causes, diarrheagenic Escherichia coli (DEC) is the most important etiologic agent of childhood diarrhoea and represents a major public health problem in developing countries. New evidence suggests that major differences in virulence among groups of DEC pathotypes may be related to the presence of specific pathogenicity islands (PAIs). METHODOLOGY Multiplex an...
