Response to seasonal drought in three cultivars of Ceratonia siliqua: leaf growth and water relations
The responses of leaf growth and leaf water relations to seasonal drought were
monitored, during two successive years, in three cultivars of Ceratonia siliqua L.
growing in the field, in the South of Portugal. In leaves from the current year growth
bulk leaf water relations parameters were characterised using pressure-volume analysis,
and morphometric measurements of xylem in petioles were undertaken. The three
cultivars under study (Galhosa, Espargal and Mulata) differed as to the seasonal pattern
of leaf initiation: in Galhosa a sharp peak of leaf initiation occurred in June, soon before
the period in which the highest leaf expansion rates were determined; on the other two
cultivars (Espargal and Mulata), not only the onset of leaf growth occurred earlier, but
they continued producing new leaves throughout the summer period. The diurnal pattern
of water relations determined in recently-expanded leaves indicated that Galhosa was
the only cultivar in which, during midsummer, leaf water potential was not decreased
below the turgor loss point and leaf relative water content remained above 90%.
Although no conclusive evidence was found for the occurrence of osmotic adjustment in
recently-expanded leaves, during the dry season following leaf formation a seasonal
decrease in osmotic potential sufficient to maintain turgor was detected in the leaves of
Galhosa but not for the other cultivars. As to the anatomy of the xylem at the petioles,
the widest xylem conduits were recorded in Galhosa. This might contribute to explain
why in this cultivar midday leaf water potential never decreased below –2.0 MPa even
at the end of summer drought season
Marine Isotope Stage 11c in Europe:Recent advances in marine–terrestrial correlations and their implications for interglacial stratigraphy – a review
The interglacial known as MIS 11c (c. 426 000–396 000 years ago) receives intensive international interest because of its perceived role as an analogue for the current interglacial and its importance for understanding future climate change. Here we review the current understanding of the stratigraphy of this interglacial in Europe. This study considers (i) the evidence for the environmental history of this interglacial as reconstructed from the varved lake records from northern Europe, (ii) the climate history of MIS 11c as preserved in the long pollen records of southern Europe and (iii) a comparison of both of these with marine records from the North Atlantic. The result of this review is a discussion of the evidence for millennial and centennial scale climate change found in European records of MIS 11c,the patterns of warming that are seen across this interglacial and the discrepancy in aspects of the duration of this interglacial that seems to exist between the marine and terrestrial records of this warm period. A review of the recent advances in the study of MIS 11c in Europe confirms its importance for understanding both the past evolution of the Holocene and the future patterns of long-term climate change
Challenges in the Definitive Diagnosis of Niemann–Pick Type C—Leaky Variants and Alternative Transcripts
(This article belongs to the Section Genetic Diagnosis)Niemann-Pick type C (NPC, ORPHA: 646) is a neuro-visceral, psychiatric disease caused predominantly by pathogenic variants in the NPC1 gene or seldom in NPC2. The rarity of the disease, and its wide range of clinical phenotypes and ages of onset, turn the diagnosis into a significant challenge. Other than the detailed clinical history, the typical diagnostic work-up for NPC includes the quantification of pathognomonic metabolites. However, the molecular basis diagnosis is still of utmost importance to fully characterize the disorder. Here, the authors provide an overview of splicing variants in the NPC1 and NPC2 genes and propose a new workflow for NPC diagnosis. Splicing variants cover a significant part of the disease-causing variants in NPC. The authors used cDNA analysis to study the impact of such variants, including the collection of data to classify them as leaky or non-leaky pathogenic variants. However, the presence of naturally occurring spliced transcripts can misdiagnose or mask a pathogenic variant and make the analysis even more difficult. Analysis of the NPC1 cDNA in NPC patients in parallel with controls is vital to assess and detect alternatively spliced forms. Moreover, nonsense-mediated mRNA decay (NMD) analysis plays an essential role in evaluating the naturally occurring transcripts during cDNA analysis and distinguishing them from other pathogenic variants' associated transcripts.This research was funded by national funds through FCT—Fundação para a Ciência e a Tecnologia, I.P., in the scope of the project EXPL/BTM-TEC/1477/2021.

Financial inclusion in Mexico ¿Where we are? A theoretical reflection
Looking into Mexico’s situation regarding financial inclusion, we find there is a lot to do. Financial inclusion should be a more inclusive and important concept and turn into a global agenda. Therefore, financial inclusion is defined as the access and use of financial services under an appropriate regulation that guarantees protection schemes for consumers and promotes financial education in order to improve financial capabilities in all population segments. During the investigation to approach the concepts of access, use, protection and defense of consumers as well as financial education. It is concluded that the financial inclusion topic not only refers to the number of people linked to the financial system through savings and credit, but also to the efficient access to payment systems and tools. This topic is defined as the ease of access to the range of financial products and services, that allow people to effectively manage their money, regardless of their income level or social status. The importance of implementing this inclusion process is the cost implied by not being prepared for a healthy financial life; the less knowledge one has, the greater the debt incurred, and the quality of life is affected. Heightening, in this way, the economic differences in the population and forcing the policies sought for by the government to compensate for the damage caused by disinformation
An Evaluation of the Contemporary Uses and Cultural Significance of Mammals in Mexico
We evaluated current uses of wild mammals by indigenous and mestizo communities in Mexico by extracting data from 59 sources published or produced between 1987–2017, covering data from 240 localities and 3,905 questionnaires. We then calculated a Cultural Value Index (CVI) previously applied to plants to quantify resource use and assess the cultural significance of each mammal. A total of 82 species were reported, and the animals with the highest cultural importance according to their CVI (in brackets) were two species of deer (Odocoileus virginianus [18.32] and Mazama temama [10.04]), as well as the nine-banded armadillo (Dasypus novemcinctus [14.18]), white-nosed coati (Nasua narica [14.75]), collared peccary (Pecari tajaccu [11.90]), northern raccoon (Procyon lotor [11.28]) and spotted paca (Cuniculus paca [9.84]). The most common uses were for food, to reduce the damage or harm they cause, and for medicinal purposes, with O. virginianus, P. lotor, N. narica, and D. novemcinctus frequently hunted for all these reasons. Our analysis also highlighted the hunting of rarer species of national conservation concern, including commercial trading of body parts of the felids Panthera onca, Leopardus pardalis, and Leopardus wiedii. By quantifying the ethnozoological significance of wildlife to indigenous communities, indices such as CVI provide a robust measure of the extent of use and preference for particular species or taxa. This adds to the body of evidence used to develop effective regulations and laws related to harvesting and hunting, and helps promote a more sustainable and long-term approach to the use of natural resources

From a Conventional to an Inclusive Teaching Classroom
Inclusive education constitutes a point of inclination in policy development and care practices to student populations and social diversity. There are goals and strategies in the Mexican educational system which demonstrate the government’s interest to promote equity and equality opportunities for the entire vulnerable population. These policies are based on the need to recognize the right of people with special educational needs to quality education. Consequently, one of the goals of Plan Nacional de Desarrollo 2019-2024, it is a social policy which has actions to offer education for the entire population and sustainable development.
Therefore, El Tecnológico Nacional de México contributes with a cross-cutting strategy to the evolution with inclusion, total equality and sustainable development through inclusive education.
In this understanding, the purpose of this project is to design an action plan which allows to change a conventional teaching classroom to an inclusive teaching classroom in order to attend people with special educational needs belonging to priority groups of Tecnológico Nacional de México
Travel Time Estimation from Multiple Data Sources
Travel time is the best indicator of the level of service in a road link, and perhaps the most important variable for measuring congestion. This paper presents a method for estimating accurate travel times in toll highways using data from multiple sources, as loop detectors and toll tickets. The proposed methodology consists of a data fusion technique using different travel time
estimations in order to obtain a more accurate fused value with less error than individual estimations by itself. Finally results obtained in the application of the methodology to the AP-7 highway, near Barcelona in Spain, are presented.Peer Reviewe
Plasticity of Dendritic Spines. Not Only for Cognitive Processes
Excitatory synaptic transmission is associated with the input of “new” information at synaptic junctions established by dendritic spines. The role that each type of spine plays in the transmission of the synaptic impulses is different. Indeed, there is a close relationship between the shape of spines and the differential processing of the excitatory synaptic information that is relayed to them, influencing in turn the transmission of synaptic information related to several psychoneural processes
