Banka humanog mlijeka u Hrvatskoj:prva iskustva

Donated human milk is the best substitute for breast milk in the case when the mother cannot feed her baby. Human milk banks provide safe and high quality donated human milk. That was the reason why the Human Milk Bank was established in the Croatian Tissue and Cell Bank at the Zagreb University Hospital Centre in January 2020. The Bank works in accordance with the Law on the Application of Human Tissues and Cells. In this paper, we present the results of the Bank work since from its opening until June 2020. Due to logistic reasons caused by the COVID-19 epidemic and the earthquake in Zagreb, the Human Milk Bank did not collect milk for 43 days. Milk was donated by 31 mothers. Their median age was 31 years and 81% of them had high education level. In 52% of cases, mothers started donating milk three months after giving birth. Most donors donated milk only once (45%). The median period of donation was 46 days. The majority (52%) of donors gave birth for the first time, in the expected term of childbirth (94%), birth weight was >2500 g. Only three of donors’ children (9%) were in intensive care. A total of 175.5 L of milk were collected (mean 5.7 L per donor), of which 151.5 L met the requirements of input quality control, and 141 L were pasteurized. A critical number of viable aerobic and facultative bacteria were identified in 32.6% of milk pools prepared for pasteurization, and 8.9% after pasteurization. For clinical use, 78.7 L were dispensed in three neonatal intensive care units. The Human Milk Bank has already shown the importance of its activities during the first months of operation. In order to be able to meet the needs for donated human milk at the national level, it is necessary to constantly inform mothers about the importance of human milk and to promote its donation.
Sinapsien ikuspegi modernoa: zelulaz kanpoko matrizearen funtzioa konexio neuronalean

The last theory about synapse, called tetrapartite synapse, adds a fourth partner in the information transport between neurons and synaptic remodeling: the extracellular matrix (ECM). In this way, presynaptic neuron, postsynaptic neuron, glia and ECM should be the neuronal connections elements. ECM is constituted by a lot of molecules with different function and by the interactions between them. Its relevance is also related to its functional alterations, which could derive in neurodegenerative diseases and neuropsychiatric disorders. In conclusion, nowadays ECM is an essential tool for the health science that has to be studied and investigated. In the present article, we first briefly explain the bipartite and tripartite synapse theories, and we then focus on the tetrapartite synapse concept. Finally, the relevance of the latest findings over the ECM in some pathologies are mentioned.
Revisiting tradeoffs in Rubisco kinetic parameters

Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (Rubisco) is not only the dominant enzyme in the biosphere, responsible for the vast majority of carbon fixation, but also one of the best characterized enzymes. Enhanced Rubisco catalysis is expected to increase crop yields, but a substantially improved enzyme has evaded bioengineers for decades. Based on correlations between Rubisco’s kinetic parameters, it is widely posited that tradeoffs stemming from the catalytic mechanism strictly constrain Rubisco’s maximum catalytic potential. Though compelling, the reasoning that established that view was based on data from only ≈20 organisms. Here we re-examine these tradeoffs with an expanded dataset including data from >200 organisms. We find that most correlations are substantially attenuated, with the inverse relationship between carboxylation kcat and specificity SC/O being a key example. However, the correlation predicted by one tradeoff model is stronger and more significant in our expanded dataset. In this model, increased catalytic efficiency (kcat/KM) for carboxylation requires a similar increase in catalytic efficiency for the competing oxygenation reaction, evidenced here by a strong power-law correlation between those catalytic efficiencies. In contrast to previous work, our results imply that Rubisco evolution is constrained mostly by the physicochemical limits of O2/CO2 recognition, which should reframe efforts to understand and engineer this very central enzyme. Significance All plants, algae and cyanobacteria rely on the Calvin-Benson-Bassham (CBB) cycle for growth. Rubisco is the central enzyme of the CBB cycle and the most abundant enzyme on Earth. While it is often claimed that Rubisco is slow, its catalytic rate is just below the average enzyme. Yet it is surprising that Rubisco is not faster given its centrality and abundance. Previous analyses of Rubisco kinetic parameters raised doubts that the enzyme can be improved. Here we examine a new compendium of Rubisco kinetic parameters for evidence of proposed constraints on Rubisco catalysis. Only one proposal is strongly supported by the data, which argues for re-evaluation of our understanding of one of the most impactful proteins in Earth’s history.
Cyber-Resilient Cooperative Control of Bidirectional Interlinking Converters in Networked AC/DC Microgrids

Bidirectional interlinking converters (BICs) are building blocks of the networked ac/dc microgrids (ac/dc NMGs). Such BICs are controlled using the communication assisted cooperative control thus forming tightly coupled cyber-physical systems (CPSs). One of lethal problems in such CPS is its vulnerability to cyber-attacks. In this article, a cyber-resilient cooperative control for BICs in ac/dc NMGs is proposed to enhance the system resilience under false signal injection attacks. The proposed control can maintain the frequency/voltage regulation and real/reactive power sharing among multiple BICs under both single and multiple node attacks. The suitability of the proposed method is supported by the stability analysis using Lyapunov methods. Efficacy of the proposed method is demonstrated by the controller hardware-in-the-loop (CHIL) experiment. An ac/dc NMG with four BICs is developed in the OPAL-RT-based real-time simulator. The cyber-resilient controllers are implemented on four commercial programmable logic controllers by B&R automation. The CHIL-based experimental results support the effectiveness of the proposed controller under various attack scenarios.

Is there an Effect of Serotonin on Attention Deficit Hyperactivity Disorder

Background: Attention deficit hyperactivity disorder (ADHD) is a neurobiological disorder with a prevalence of 5%-10% in the world that negatively impacts school behavior and achievement. There have been many studies reveals that attention disorders are caused by the decreased levels of dopamine and norepinephrine neurotransmitter. However, particular concern nowadays are the emotional and behavioral problems. The emotional and behavioral problem is suspected to be caused by the decrease in serotonin level. The aim of this study was to determine the difference in serotonin level between ADHD and non-ADHD children. Method: This study was an observational case-control study design using random sampling method. Subject of this study was children in Bina Karya Elementary School Surabaya. ADHD severity was assessed using Conners Abreviated Rating Scale. Examination of serotonin levels in blood was done by ELISA method. Informed consent was signed by parents before the study. Data was analyzed using independent T-test. Results: 44 (23 ADHD and 21 non-ADHD) children from grade 1 to 6 was included in the study. Based on the gender, 13 children were girls and 31 children were boys. Serotonin level in ADHD children was significantly higher than non-ADHD children (2.148 ± 0.94 vs 2.006 ± 0.115 μmol/L; p = 0.0001). Conclusion: Serotonin level in ADHD children was significantly higher than non-ADHD children.
Technological Trade Composition and Performance in African Countries

A number of studies have found that spillovers or other externalities associated with trade are sector specific. Yet trade linkages are typically analysed at the macroeconomic aggregates. We analyse Africa's trade composition spanning 1980-2015, using a disaggregated and detailed classification by technological levels. We find that Africa is a net importer of capital goods and its technological export composition has remained highly concentrated in primary goods, which has contributed to a decline in Africa's share of global exports. We also find that regions within Africa have similar technological export composition structures. A few notable countries that have managed to transform their export composition into more semi-processed and relatively high technology exports are the leading importers of capital goods, are better financially developed and better endowed with human capital, infrastructure, and institutions than other African countries.

Perception, Motivation, and Satisfaction of Female Tourists with Their Visit to the City of Cordoba (Spain)

The cultural and historical heritage of a city is a major resource for attracting tourists. Therefore, determining how to perceive and identify the characteristics of persons visiting a locality attracted by its heritage is relevant for the purpose of better meeting their expectations and needs. This research focuses on understanding the perceptions, motivations, and satisfaction of women visiting Cordoba (Spain). Thus, on the basis of a questionnaire completed by women visiting Cordoba between the months of June and November 2019, statistical analysis was conducted. Using various multivalent case-grouping techniques, segments of tourists holding similar perceptions of cultural heritage were detected. Moreover, non-parametric statistical techniques highlighted significant differences between the valuations obtained in the various segments. This analysis exposed a segment of women who, known as absorptive tourists, are characterized by a high cultural motivation to visit the city of Cordoba linked to the heritage sites they have visited. The conclusions obtained herein should be useful for adjusting the city’s provision of tourism services to satisfy the demand of female tourists visiting the city.
An Online Self Cold Startup Methodology for PEM Fuel Cells in Vehicular Applications

This paper puts forward an adaptive cold start strategy for a proton exchange membrane fuel cell (PEMFC) based on maximum power mode. The proposed strategy consists of a water evacuation process after PEMFC shutdown and a self-heating process at PEMFC cold startup. To maximize the performance of the suggested strategy, an optimal operating condition for the cold start procedure is sought first. In this respect, an experimental parametric study is performed to explore the impact of fan velocity, micro-short circuit, anode pressure, and purge procedure on the PEMFC cold start performance. After laying down the proper conditions, the proposed cold start procedure is implemented on a test bench for experimental validations. The self-heating process is based on an online adaptive algorithm that maximizes the PEMFC's internal heat depending on its operating parameters’ variation. In fact, this algorithm attempts to keep the current density at high levels, leading to PEMFC's performance improvement achieved by membrane hydration and temperature increase. The experimental results confirm the effectiveness of the proposed strategy, which presents a fast and cost-effective PEMFC's cold start.
Important areas for the conservation of the European Roller Coracias garrulus during the non-breeding season in southern Africa

Summary The identification of threats to migratory species of conservation concern and the relevance of protected areas for them is often biased towards breeding areas. The European Roller Coracias garrulus is a long-distance migrant experiencing a pronounced decline throughout its breeding range, which has been attributed to the degradation of open agricultural habitats. However, its conservation status in non-breeding areas in Africa remains unstudied. Land cover change is a major threat affecting migratory birds in their wintering grounds, therefore identifying important areas for their protection at this stage is a priority. Here we used occurrence data during the wintering season and ecological niche models to identify key land cover and areas used by Rollers in Africa. First, we used 33 filtered locations from six satellite-tracked birds breeding in Spain to describe suitable wintering areas for the Spanish population (westernmost part of the Eurasian breeding range). We also used 1,167 occurrence data in southern Africa from open-access databases and bird atlases to characterise the overall wintering range of the species. The Spanish population occupied a relatively small area in the north-western part of southern Africa, and a narrow range of land covers. Open grassland, less steep areas and those with sparse tree cover are correlated with suitability. In all, 18.06% of suitable wintering areas for the Spanish population overlapped with protected areas. The overall population of Rollers occupied a wider area and range of land cover. Tree cover was the most important variable affecting suitability, with areas without tree cover being the least suitable. We found that 9.58% of suitable wintering areas for the overall population overlapped with protected areas. Our results suggest that Rollers from different origins (breeding populations) use separate, but overlapping, wintering areas and may have different habitat requirements, and therefore, population-specific conservation strategies in these areas might be needed to fully protect the species.

Proximity sensors reveal social information transfer in maternity colonies of Common noctule bats

Bats are a highly gregarious taxon suggesting that social information should be readily available for making decision. Social information transfer in maternity colonies might be a particularly efficient mechanism for naïve pups to acquire information on resources from informed adults. However, such behaviour is difficult to study in the wild, in particular in elusive and small-bodied animals such as bats. The goal of this study was to investigate the role of social information in acquiring access to two types of resources, which are crucial in the life of a juvenile bat: suitable roosting sites and fruitful feeding grounds. We hypothesized that fledging offspring will make use of social information by following informed members of the social groups to unknown roosts or foraging sites. In the present study we applied for the first time the newly developed miniaturized proximity sensor system ‘BATS’, a fully automated system for documenting associations among individual bats both while roosting and while on the wing. We quantified associations among juveniles and other group member while switching roosts and during foraging. We found clear evidence for information transfer while switching roosts, mainly among juveniles and their genetically identified mothers. Anecdotal observations suggest intentional guidance behaviour by mothers, indicated by repeated commuting flights among the pup and the target roost. Infrequent, short meetings with colony members other than the mother indicate local enhancement at foraging sites, but no intentional information transfer. Our study illustrates how advances in technology enable researchers to solve long-standing puzzles. Miniaturized proximity sensors facilitate the automated collection of continuous data sets and represent an ideal tool to gain novel insights into the sociobiology of elusive and small-bodied species.
V-Eye: A Vision-Based Navigation System for the Visually Impaired

Numerous systems for helping visually impaired people navigate in unfamiliar places have been proposed. However, few can detect and warn about moving obstacles, provide correct orientation in real time, or support navigation between indoor and outdoor spaces. Accordingly, this paper proposes V-Eye, which fulfills these needs by utilizing a novel global localization method (VB-GPS) and image-segmentation techniques to achieve better scene understanding with a single camera. Our experiments establish that the proposed system can reliably provide precise locations and orientation information (with a median error of approximately 0.27 m and 0.95°); detect unpredictable obstacles; and support navigating both within and between indoor and outdoor environments. The results of a user-experience study of V-eye further indicate that it helped the participants not only with navigation, but also improved their awareness of obstacles, enhanced their spatial awareness more generally, and led them to feel more secure and independent while walking.
The Impact of Corporate Social Responsibility on Customer Satisfaction and Customer Perceived Value

CSR, short for corporate social responsibility, is a key issue both for companies and all stakeholders. Many companies invest a lot in CSR in order to obtain new customers attracted by identification of its values and missions. In turn, customers need a brand with good image and reputation to show who they are. The purpose of this study are to analyze how CSR impact customer satisfaction, how customer perceived value, and whether Chinese customers feel more satisfied with the domestic companies with well performed CSR than those companies without that. The relevant data in this paper are collected from questionnaire and are employed to text hypotheses about CSR through SPSS. And the results show that Chinese customers’ satisfaction and perceived value can be enhanced by the well performed CSR of the domestic companies.
Exploiting Antenna Diversity to Enhance Hybrid Cooperative Non-Orthogonal Multiple Access

Cooperative non-orthogonal multiple access (C-NOMA) is a novel multiple access technology that is considered as a promising solution for 5G and beyond. The technique has been proposed as a combination between NOMA and cooperative communications, such as device-to-device (D2D) communications. In this letter, we will address some limitations of the state-of-the-art C-NOMA model and promote an enhancement to the contemporary version. The improvement is based on an exhaustive exploitation of the antennas mounted at the users devices. Based on this, we revisit the rate analysis and the performance optimization of C-NOMA systems. Simulation results reveal the robustness of the proposed scheme in the presence of high self-interference (SI) and insightful comparisons with other previously proposed schemes in the literature are provided.
Pomegranate (Punica granatum L.) Peel Extracts Inhibit Microbial Growth and Lipid Oxidation in Minced Shrimps Stored at 4°C

ABSTRACT Pomegranate peel is inherited with diverse functional properties that improve storage stability and nutritional quality of edible goods. This research was aimed at evaluating antioxidant and antimicrobial properties of pomegranate peel hydro-alcoholic extracts and to determine in situ efficacy of extracts in controlling microbial growth and lipid oxidation of shrimp meat. The results suggest that pomegranate peel ethanolic extracts (PoPetx) have significantly higher (p < 0.05) phenolic contents, 169 mg GAE/100 g accompanied with 90% free radical scavenging activities. Contrary to the normal control, incorporation of PoPetx @ 2.0% (w/w) in minced shrimp meat increased thiobarbituric acid reactive species generation by 10% during 28 days of storage at 4°C. Supplementing PoPetx @ 0.5–2.0% (w/w) to shrimp meat has shown a comparable microbial inhibitory action against total plate counts and Staphylococcus spp. The study concludes that application of pomegranate peel extracts in minced shrimp is a viable strategy to preserve chemical and microbiological quality of shrimp and products of sea origin.
