Tissue flossing around the thigh does not provide acute enhancement of neuromuscular function
Armin Paravlić, Jure Segula, Kristina Drole, Vedran Hadžić, Maja Pajek, Janez Vodičar, 2022, original scientific article

Abstract: Nowadays, various methods are used for acute performance enhancement. The most recent of these is tissue flossing, which is becoming increasingly popular for both performance enhancement and rehabilitation. However, the effects of flossing on athletic performance have not been clearly demonstrated, which could be due to differences in the methodology used. In particular, the rest periods between the end of the preconditioning activity and the performance of the criterion task or assessment tools varied considerably in the published literature. Therefore, the present study aimed to investigate the effects of applying tissue flossing to the thigh on bilateral countermovement jump performance and contractile properties of vastus lateralis (VL) muscle. Nineteen recreational athletes (11 males; aged 23.1 ± 2.7 years) were randomly assigned to days of flossing application (3 sets for 2 min of flossing with 2 min rest between sets) with preset experimental pressure (EXP = 95 ± 17.4 mmHg) or control condition (CON = 18.9 ± 3.5 mmHg). The first part of the measurements was performed before and after warm-up consisting of 5 min of cycling followed by dynamic stretching and specific jumping exercises, while the second part consisted of six measurement points after flossing application (0.5, 3, 6, 9, 12, 15 min). The warm-up improved muscle response time (VL = -5%), contraction time (VL = -3.6%) muscle stiffness (VL = 17.5%), contraction velocity (VL = 23.5%), jump height (13.9%) and average power (10.5%). On the contrary, sustain time, half-relaxation time and take-off velocity stayed unaltered. Flossing, however, showed negative effects for muscle response time (F = 18.547, p < 0.001), contraction time (F = 14.899, p < 0.001), muscle stiffness (F = 8.365, p < 0.001), contraction velocity (F = 11.180, p < 0.001), jump height (F = 14.888, p < 0.001) and average power (F = 13.488, p < 0.001), whereas sustain time, half-relaxation time and take-off velocity were unaffected until the end of the study protocol regardless of condition assigned and/or time points of the assessment. It was found that the warm-up routine potentiated neuromuscular function, whereas the flossing protocol used in the current study resulted in fatigue rather than potentiation. Therefore, future studies aimed to investigate the doseresponse relationship of different configurations of preconditioning activities on neuromuscular function are warranted.

Geophysical investigations in the Radovna River Spring area (Julian Alps, NW Slovenia)
Anja Torkar, Marjana Zajc, Jure Atanackov, Andrej Gosar, Mihael Brenčič, 2021, original scientific article

Abstract: The Radovna River Valley is located in the north-western part of Slovenia in the Julian Alps, where there is an extensive intergranular aquifer whose depth to pre-Quaternary bedrock is unknown. Therefore, to obtain information about the depth of the valley and the geometry of the aquif er two geophysical methods were used in our study; ground penetrating radar (GPR) and seismic reflection method. The low-frequency GPR method has shown to be useful for determining the depth of the groundwater and the predominant groundwater recharge. Also, the high-resolution seismic method provided an insight about the morphology of the pre-Quaternary basement with the deepest point at 141 meters below surface. Measurements of hydrogeological parameters such as groundwater level and river discharge measurements were carried out in the study area. Both data analyses showed that groundwater level and river discharge are highly fluctuatingand rapidly changing, indicating a well-permeable aquifer, implying that such an aquifer is extremely sensitive and vulnerable to extreme climate events. Both the geophysical methods and the hydrogeological information have provided important information about the morphology of the valley and the alluvial aquifer, as well as increasing the knowledge about the Radovna springs system, which will contribute very important information for future hydrogeological studies.

"Kosovo, My Land"? : Slovenians, Albanians, and the Limits of Yugoslav Social Cohesion
Jure Ramšak, 2021, original scientific article

Abstract: The author examines the Kosovo crisis in the context of the pluralisation and democratisation of Slovenian society in the 1980s and early 1990s. This issue became a catalyst not only for the repositioning of structures of party leadership in relation to Belgrade, but also with respect to general public debates. By charting individual stages of the critical decade of 1981%1991, the author presents Slovenian perceptions of Kosovo%s political, economic, and social issues, first through the works of neo-Marxist critics and later through the activism of a group of left-liberal intellectuals, which included the provision of legal support and a high-profile social action related to the violations of Kosovar Albanian human rights. The author discusses the constraints encountered by this brief attempt to establish a pan-Yugoslav civil society initiative. At the same time, he shows how the complexities of the Kosovo crisis were used to coalesce the Slovenian nation into flight from Yugoslavia.

The crumbling touchstone of the Vatican's ostpolitik : relations between the Holy see and Yugoslavia, 1970-1989
Jure Ramšak, 2021, original scientific article

Abstract: Based on Yugoslav archival sources, the paper analyses the relationship between the Holy See and Yugoslavia as the only Eastern European socialist state with which the former had official diplomatic relations. The relationship between the Holy See and socialist Yugoslavia provides insight into the precarious position of the Catholic Church in Yugoslavia, but also into the issues and dilemmas that the Holy See faced in terms of its Ostpolitik towards Eastern European socialist regimes. The article initially centres on the parallels between the Holy See and the foreign policy agenda of non-aligned Yugoslavia, especially during the papacy of Paul VI, when both actors shared an understanding of the acute problems of the Global South. It then analyses the stance of the Holy See towards the Yugoslav domestic policy of self-management that claimed that this system could present a viable environment for the life of believers in modern socialist society. The analysis closes with an in-depth examination of the role of the Holy See in the process of convergence between religion and nationalism during the 1980s, in which the Vatican did not play as clear-cut a role as it has generally been ascribed and proved unable to tackle this formidable phenomenon.

Abstract: There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPAR[gamma]:Peroxisome proliferator-activated receptor, NF[kappa]B: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2[alpha]:Elongation initiation factor 2[alpha]). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT1R axis (AT1R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity.
