High alkaline phosphatase activity in phosphate replete waters: The case of two macrotidal estuaries

The occurrence of alkaline phosphatase activity (APA) that hydrolyses organic phosphorus into phosphate (PO4) is commonly related to PO4 deficiency of oceanic, coastal and fresh waters. APA is almost never investigated in PO4-rich estuaries, since very low activities are expected to occur. As a consequence, microbial mineralization of organic phosphorus into PO4 has often been ignored in estuaries. In this study, we examined the importance of potential APA and the associated microbial dynamics in two estuaries, the Aulne and the Elorn (Northwestern France), presenting two different levels of PO4 concentrations. Unexpected high potential APA was observed in both estuaries. Values ranged from 50 to 506 nmol L−1 h−1, which range is usually found in very phosphorus-limited environments. High potential APA values were observed in the oligohaline zone (salinity 5–15) in spring and summer, corresponding to a PO4 peak and a maximum bacterial production of particle-attached bacteria. In all cases, high potential APA was associated with high suspended particulate matter and total particulate phosphorus. The low contribution of the 0.2–1 μm fraction to total APA, the strong correlation between particulate APA and bacterial biomass, and the close relationship between the production of particle-attached bacteria and APA, suggested that high potential APA is mainly due to particle-attached bacteria. These results suggest that the microbial mineralization of organic phosphorus may contribute to an estuarine PO4 production in spring and summer besides physicochemical processes.

THE MIDDLE-DNIESTER CULTURAL CONTACT AREA OF EARLY METAL AGE SOCIETIES. THE FRONTIER OF PONTIC AND BALTIC DRAINAGE BASINS IN THE 4TH/3RD-2ND MILLENNIUM BC.

The paper discusses the taxonomy and autogenesis of the cycle of early ‘barrow cultures’ developed by the local communities of the middle Dniester Area or, in a broader comparative context, the north-western Black Sea Coast, in the 4th/3rd-2nd millennium BC . The purpose of the study is to conduct an analytical and conceptual entry point to the research questions of the dniester Contact area, specifically the contacts between autochthonous ‘late Eneolithic’ communities (Yamnaya, Catacomb and Babyno cultures) and incoming communities from the Baltic basin . The discussion of these cultures continues in other papers presented in this volume of Baltic-Pontic Studies.

Studying the role of the strawberry Fra protein family in the flavonoid metabolism during fruit ripening

Strawberry fruits are highly appreciated worldwide due to their pleasant flavor and aroma and to the health benefits associated to their consumption. An important part of these properties is due to their content in secondary metabolites, especially phenolic compounds, of which flavonoids are the most abundant in the strawberry fruit. Although the flavonoid biosynthesis pathway is uncovered, little is known about its regulation. The strawberry Fra a (Fra) genes constitute a large family of homologs of the major birch pollen allergen Bet v 1 and for which no equivalents exist in Arabidopsis. Our group has shown that Fra proteins are involved in the formation of colored compounds in strawberries (Muñoz et al., 2010), which mainly depends on the production of certain flavonoids; that they are structurally homologs to the PYR/PYL/RCAR Arabidopsis ABA receptor, and that they are able to bind flavonoids (Casañal et al., 2013). With these previous results, our working hypothesis is that the Fra proteins are involved in the regulation of the flavonoids pathway. They would mechanistically act as the ABA receptor, binding a protein interactor and a ligand to regulate a signaling cascade and/or act as molecular carriers. The main objective of this research is to characterize the Fra family in strawberry and gain insight into their role in the flavonoid metabolism. By RNAseq expression analysis in ripening fruits we have identified transcripts for 10 members of the Fra family. Although expressed in all tissues analyzed, each family member presents a unique pattern of expression, which suggests functional specialization for each Fra protein. Then, our next approach was to identify the proteins that interact with Fras and their ligands to gain knowledge on the role that these proteins play in the flavonoids pathway. To identify the interacting partners of Fras we have performed a yeast two hybrid (Y2H) screening against cDNA libraries of strawberry fruits at the green and red stages. A protein that shares a 95% homology to the Heat stress transcription factor A-4-C like of Fragaria vesca (HSA4C) interacts specifically with Fra1 and not with other family members, which suggests functional diversification of Fra proteins in specific signaling pathways. The Y2H screening is not yet saturated, so characterization of other interacting proteins with other members of the Fra family will shed light on the functional diversity within this gene family. This research will contribute to gain knowledge on how the flavonoid pathway, and hence, the fruit ripening, is regulated in strawberry; an economically important crop but for which basic research is still very limited.

Failing to meet expectations:the meaning of intimate partner violence for Pakistanis

Background: Intimate Partner Violence (IPV) is a major social and public health problem affecting people across cultures, religions and societies. Much research has been undertaken to offer understanding and explanations of this phenomenon, its determinants, and its consequences in developed countries around the world. However, there is still a paucity of research on IPV in many areas of the developing world such as Pakistan. Although various studies have been conducted to demonstrate the prevalence of IPV in the country, none of the studies have tried to explore the meaning of IPV from the perspective of Pakistani people. Aim: This study aimed to explore understandings of Pakistani men and women of IPV. It aimed to develop a theory to explain the meaning of IPV and the process through which it occurs, from the perspective of Pakistani people. Methods: The study utilised a qualitative approach with constructivist grounded theory methods and analysis techniques. Data was collected from Karachi, Pakistan and Sheffield, UK. Forty one people (20 from Pakistan and 21 from UK) participated in the study. Findings: The participants identified IPV as a serious concern. Although verbal abuse is often included in definitions of IPV, the participants did not consider shouting, raising the voice or scolding as a type of violence. Hitting, beating, pushing, throwing objects, and pulling hair were identified as acts of physical violence, and non-consensual sex was identified as a form of sexual abuse. Participants identified failure to meet role expectations of a husband or wife as a key contributor to the development of conflict between partners which could lead to IPV. Examples of various expectations from a wife include completing household chores, looking after husband, looking after children, looking after in laws, respecting and adjusting to in-law's customs and traditions. Important expectation from a husband include provision of finances, acting as a bridge, maintaining a balance between his wife and other family members particularly his mother and sisters, and taking the responsibility for his wife and children. Failure to meet these expectations could contribute to conflict and subsequent violence. This appeared to be shaped by cultural issues such as common use of arranged marriages, the rarity of divorce and the centrality of the extended family to the intimate partnership. Implications: Any interventions aimed at reducing IPV in Pakistani people must consider the meaning and causes of IPV from the perspective of that group.

El rol de las redes de apoyo transnacional en la evolución del régimen de trata de personas en la región del mekong, 2004-2015

Con el fin de la unipolaridad no sólo se fortalecieron mecanismos de gobernanza global como los Regímenes Internacionales, sino también se fortalecieron actores no estatales. A pesar de la importancia que tomaron estos dos elementos aún no existe una teoría que explique exhaustivamente la relación que existe entre ellos. Es por lo anterior que, la investigación busca responder de qué manera el rol de las Redes de Apoyo Transnacional ha incidido en la evolución del régimen de tráfico de personas en la Región del Mekong. Asimismo tiene como objetivo comprender las relación entre el Régimen y las Redes de Apoyo Transnacional a través de la formulación de un caso de estudio basado en metodologías cualitativas, específicamente, en el análisis teórico-constructivista y el análisis de contenido de documentos producidos por actores estatales y no estatales.
