Field work focused on the Kuedinskie Kluchiki locality, Perm region, Urals, Russia, which contains a rich assemblage of diverse fossil organisms including higher plants(equisetophytes, pteridosperms, ginkgophytes, conifers, vojnovskyans) represented by stems, leaves and reproductive organs;invertebrates(mollusks, arthropods), and tetrapods(temnospondyl amphibians, seymouriamorphs, cotylosaurs, synapsids, diapsids), as well as bony fishes. General characteristics of the taxonomical composition of the Kuedinskie Kluchiki locality are given. A new peltaspermalean pteridosperm taxon, Compsopteris longipinnata sp. nov., and a voltzialean conifer Archaeovoltzia kuedensis sp. nov. are described. General considerations on the paleoecologic and paleogeographic conditions of the Kuedinskie Kluchiki locality origin are given.

Background: The Anonymous Screening and Information Centre (CADI) is the oldest screening centre of HIV from Burkina Faso. Since its opening, no analysis on the evolution of Human Immunodeficiency Virus (HIV) prevalence has been carried out. Objective: The study aimed to describe the dynamics of HIV infection when managing centres offering voluntary counselling and testing to client, such as the Screening and Counselling Centre (CADI), in Bobo Dioulasso, Burkina Faso. Patients and Methods: A cross-sectional study was performed including people screened at the CADI from May 1996 to June 2014. Pearson khi2 test and Cuzick trend test were used with a 5% significance level. Results: From 7.1% of the 11,451 cases analyzed, the average age of clients screened was 30 ± 10.83 year-old. There was a female predominance (sex ratio = 0.8). The 16.4% (15.7 - 17.1) of the cases from the 11,451 clients included in our study were tested HIV positive. The global prevalence rate of HIV in the centre has significantly decreased from 46.2% in 1996 to 1.5% in 2014 (p Conclusion: The behaviour change could be a justification for the decline in HIV prevalence at the centre, hence the importance of sensitization campaigns.

Background: The diagnosis of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) remains a constraint for some populations in sub-Saharan Africa. This study aimed to determine the prevalence of HBV and HCV in people living with HIV and to evaluate the performance of a combined rapid test for the simultaneous detection of HIV, HBV, and HCV. Methods: This is a cross-sectional study that took place from February 2017 to November 2018 and included 139 HIV-infected individuals followed up at different medical centers in Ouagadougou, Burkina Faso. HBV and HCV serology tests were performed on-site using finger prick whole blood with HIV/HCV/HBsAg combined rapid test and then serum with two reference tests “Architect HBsAg Qualitative” and “Architect HIV Ag/Ab Combo”. Results: The mean age of the participants was 57 ± 8 years. Of the 139 participants, 10% (14/139) were HIV-1 positive, 71.9% (100/139) were HIV-2 positive, and 18.0% (25/139) were HIV-1/HIV-2 coinfected. The sensitivity and specificity of the HIV/HCV/HBsAg combined rapid test were 33.33% vs 99.11% and 20% vs 99.25% compared to Architect HBsAg Qualitative and Architect HIV Ag/Ab Combo, respectively. The Kappa and Youden Index values were 0.4262 and 0.3244 and 0.2707 and 0.1925, respectively, compared to each of the two reference tests. Conclusion: The results show that the HIV/HCV/HBsAg combined rapid test has poor diagnostic efficiency and should not be recommended for the diagnosis of these viruses.

Electrochemical detection of 3-methyl-4-nitrophenol (MNP) in direct phenol oxidation occurs at high potentials and generally leads to progressive passivation of the electrochemical sensor. This study describes the use of a carbon fiber microelectrode modified with a tetrasulfonated nickel phthalocyanine complex for the detection of MNP at a lower potential than that of direct phenol oxidation. The MNP voltammogram showed the presence of an anodic peak at -0.11 V vs SCE, corresponding to the oxidation of the hydroxylamine group generated after the reduction of the nitro group. The effect of buffer pH on the peak current and SWV parameters such as frequency, scan increment, and pulse amplitude were studied and optimized to have better electrochemical response of the proposed sensor. With these optimal parameters, the calibration curve shows that the peak current varied linearly as a function of MNP concentration, leading to a limit of detection (LoD) of 1.1 μg/L. These results show an appreciable sensitivity of the sensor for detecting the MNP at relatively low potentials, making it possible to avoid passivation phenomena.

The assessment of the local community perception of the value of riparian corridors is relevant to understand their attitude towards the conservation of such ecosystem. We conducted a semi-structured survey on the perception and importance attributed to the ecosystem services (ESs) provided by riparian corridors in 368 households across 70 villages located in a buffer zone of 5 km of servitude around the permanent rivers of the Upper Oueme watershed in Benin. We found that local communities easily reported provisioning and cultural ESs than regulating and supporting ones, indicating their misunderstanding of the main role of riparian corridor. Moreover, the supply of cropping areas was perceived as the most important ES. Educated respondents and high-income households had more knowledge of regulating ESs and supporting ESs, respectively. Overall, the highly perceived importance of the provision of cropping areas indicates a potential risk of agricultural encroachment of riparian corridors. We suggest the consideration of the current local perception of riparian corridor’s role in designing a sound environmental education aiming at the change of local population’s perception. This perception shift will promote a sustainable management of the riparian corridors.

The history of mankind contains so many illustrations of well-classified and violent struggles against various animals over crop production in agricultural fields, attacks on human life or competition in order to have access to certain natural resources. The aim of this study is to characterise the human-wildlife conflicts that occur around the KBNP, especially with regard to primates. Surveys were carried out in 260 households selected using the snowball method. The results showed that human-wildlife conflicts around the KBNP are characterised by the destruction of crops in riparian fields by monkeys, chimpanzees and gorillas, the destruction of houses, physical attacks and zoonoses. Despite the conservation and protection measures for wildlife and local populations put in place by the Park’s managers, conflicts between local populations and the Park’s wild animals are still visible. These conflicts lead to the detention of wild animals by local people roaming in the villages and to poaching on the Park’s boundaries. The weakness of the community management policy on the part of the park managers and the resentment of the indigenous peoples towards the restriction of their access to natural resources are the major constraints on the sustainable management of conflicts between the local populations and the wild animals in the KBNP. The strategies for the sustainable resolution of human-wildlife conflicts around the KBNP must be geared towards and integrated into a community conservation approach.
