Saproxylic beetles are key bioindicators of forest ecosystem quality and play essential roles in deadwood decomposition and nutrient cycling. However, their populations are increasingly threatened by habitat fragmentation, deadwood removal, and climate-driven environmental changes. For this reason, an integrated sampling method can increase the detection of species with varying ecological traits. We evaluated the effectiveness of integrative sampling methodologies to assess saproxylic beetle diversity within Sila National Park, a Mediterranean forest ecosystem of high conservation value, specifically in two beech forests and four pine forests. The sampling methods tested included Pan Traps (PaTs), Malaise Traps (MTs), Pitfall Traps (PTs), Bait Bottle Traps (BBTs), and Visual Census (VC). All specimens were identified to the species level whenever possible, using specialized dichotomous keys and preserved in the Entomological Collection TB, Unical. Various trap types captured a different number of species: the PaT collected 32 species, followed by the PT with 24, the MT with 16, the VC with 7, and the BBT with 5 species. Interestingly, biodiversity analyses conducted using PAST software version 4.17 revealed that PaTs and MTs recorded the highest biodiversity indices. The GLMM analysis, performed using SPSS software 29.0.1.0, demonstrated that various traps attracted different species with different abundances. By combining multiple trapping techniques, we documented a more comprehensive community composition compared to single-method approaches. Moreover, PaTs, MTs, and PTs recorded 20%, 40%, and 33% of the Near Threatened species, respectively. We report new records for Sila National Park, including the LC species Pteryngium crenulatum (Curculionidae) and the NT species Grynocharis oblonga (Trogossitidae). For the first time in Calabria, the LC species Triplax rufipes (Erotylidae) and the NT species Oxypleurus nodieri (Cerambycidae) and Glischrochilus quadrisignatus (Nitidulidae) were collected. Our results emphasize the importance of method diversity in capturing species with distinct ecological requirements and highlight the relevance of saproxylic beetles as indicators of forest health. These findings support the adoption of multi-method sampling protocols in forest biodiversity monitoring and management programs, especially in biodiversity-rich and structurally heterogeneous landscapes.

Ozone is a powerful destructive agent in the oxidative process of polymer composites. The destructive ability of ozone depends primarily on its concentration, duration of exposure, the type of polymer, and its matrix structure. In this work, nonwoven PLA/NR fibers with natural rubber contents of 5, 10, and 15 wt.% were obtained, which were then subjected to ozone oxidation for 800 min. The effect of ozone treatment was estimated using various methods of physicochemical analysis. The visual effect was manifested in the form of a change in the color of PLA/NR fibers. The method of differential scanning calorimetry revealed a change in the thermophysical characteristics. The glass transition and cold crystallization temperatures of polylactide shifted toward lower temperatures, and the degree of crystallinity increased. It was found that in PLA/NR fiber samples, the degradation process predominates over the crosslinking process, as an increase in the melt flow rate by 1.5–1.6 times and a decrease in the correlation time determined by the electron paramagnetic resonance method were observed. The IR Fourier method recorded a change in the chemical structure during ozone oxidation. The intensity of the ether bond bands changed, and new bands appeared at 1640 and 1537 cm⁻¹, which corresponded to the formation of –C=C– bonds. Full article

The present study aimed to investigate the electrophysiological correlates of face-identity recognition in newborn infants immediately after birth. Electroencephalographic acquisition was continuously recorded in 23 newborn infants (3 < age < 24 h of life) during the following visual task: presentation of a woman’s face for 60 s (“known face”); random presentation of 50 known faces, 50 novel women’s faces, and 50 chessboards (for 2 s each). The final sample included in ERP analyses was composed of 11 newborn infants (male/female: 6/5; age: 5 h 16′ ± 3 h 51′). A greater negative amplitude of the N290 and smaller P400 and LC2 were found in response to the known face compared with the novel one in the left hemisphere. A shorter N290 latency was detected during the known face presentation compared with the novel one, and a longer latency of the same component was observed during novel face presentation compared with the chessboard. These findings suggest that newborns process a face differently from an object at birth and that they can discriminate a new face from a familiar one previously viewed for one minute. Full article

Background/Objectives: Advanced wound healing biologics for diabetic foot ulcer (DFU) are typically withheld from persons who are at high risk for amputation. However, a prospective, single-center cohort study evaluated the use of an advanced biologic, dehydrated amniotic (DAMA) tissue as early treatment for DFUs in patients with a high risk for amputation, demonstrating benefit for a small sample. This is the report of the five-year follow-up of those high-risk participants. Methods: This chart review provides a 5-year follow-up of 18 of 20 participants in the original study. The data were collected by medical record review. Specific data points included mortality, re-ulceration and additional ulceration, amputation (minor and major), end-stage renal disease with dialysis dependence, hospitalization, and limb-threatening ischemia. Results: The 5-year mortality rate from the time of wound healing was 50% (9/18 deceased). Four of the eighteen participants (22.2%) underwent major amputation within 5 years of study completion. Two had amputations of the study limb and two had amputations of the contralateral limb. Fifty percent (2/4) of those who had amputations died within 5 years after the major amputation. Over fifty percent (55.5% or 10 out of 18) of the participants experienced the re-ulceration of the original study ulcer and 94% (17 out of 18) developed a new site ulceration. A total of 25% of the hospitalizations over the 5 years were related to DFU (infection, osteomyelitis, and sepsis). Conclusions: This small-sample 5-year follow-up shows that early treatment with dehydrated amniotic (DAMA) tissue in patients with diabetic foot ulcers of moderate-to-high amputation risk results in similar outcomes as noted in the current research on patients with low risk for amputation. In fact, this paper may suggest that advanced biologics can safely be used for early treatment in moderate-to-high amputation risk without increasing mortality and amputation over 5 years.

A new type of solid bismuth microelectrode array characterized by eco-friendly properties and the simplicity of its construction is presented for the first time. The proposed array of microelectrodes consists of exactly forty-three single capillaries of an inner diameter of about 10 µm filled with metallic bismuth and packed in one casing. The proposed sensor is reusable thanks to its distinctive design. The microelectrode properties of the proposed working electrodes were confirmed by comparing the analytical signals of cadmium and lead recorded from stirred and unstirred solutions during the deposition step. The practical application of the solid bismuth microelectrode array is presented by detailing the procedure for the simultaneous determination of Pb and Cd by anodic stripping voltammetry. The calibration graphs were linear from 5 × 10⁻⁹ to 2 × 10⁻⁷ mol L⁻¹ and 2 × 10⁻⁹ to 2 × 10⁻⁷ mol L⁻¹ for Cd(II) and Pb(II), respectively (deposition time of 60 s). The detection limits for Cd(II) and Pb(II) were equal to 2.3 × 10⁻⁹ mol L⁻¹ and 8.9 × 10⁻¹⁰ mol L⁻¹, respectively. Potential interferences were investigated. The developed procedure was successfully used for the analysis of certified water reference material and environmental water samples. Full article

The aim of our study was to test the application of a new vision training device, the EYE ROLL, for home-based eye movement training in athletes. Sixty-seven participants were randomly divided into three groups: a control group (no training); an eye movement training group with no device; and a group using the new EYE ROLL device. The results of 51 participants were used for statistical analyses after a 4-week period. Before and after the 4-week period, participants underwent the same assessment procedures: a comprehensive vision examination and saccadic eye movement recording. Before training, for both 10° and 5° stimuli, all subjects showed statistically significantly larger and faster rightward saccades compared to leftward saccades. After four weeks, the control group showed increased horizontal saccadic asymmetry and a decrease in leftward saccade amplitude. However, both velocities showed asymmetry in both visits. There were larger changes in saccadic parameters for leftward saccades, but no clear changes in saccadic response asymmetry after training. There were no consistent differences between the training groups. The EYE ROLL is a novel device that may serve as a substitute training tool for saccadic enhancement and may improve the symmetry of horizontal saccadic movements after four weeks of home-based training.

Background/Objectives: Systemic lupus erythematosus (SLE) is an autoimmune disease associated with an increased prevalence of cardiac and cerebrovascular events. Despite advancements in management, no validated tools exist that can predict the risk of ischemic stroke in SLE patients. However, several studies have demonstrated an association between a higher CHA₂DS₂-VASc score and an enhanced risk of ischemic stroke in autoimmune diseases without atrial fibrillation (AF) or atrial flutter (AFL). Recently, the European Society of Cardiology suggested the use of a revised score of CHA₂DS₂-VASc without taking sex into account (CHA₂DS₂-VA). Therefore, we sought to check if the new CHA₂DS₂-VA score might predict stroke or other cardiovascular events in SLE patients without AF/AFL. Patients and Methods: We retrospectively analyzed the records of patients with SLE treated at the University Hospital in Kraków, Poland, from 2012 to 2022. Patients with a history of AF/AFL were excluded. Results: This study enrolled 787 SLE patients without AF/AFL (aged 49 (38–60) years) with a predominance of women (n = 705, 89.58%). Common comorbidities included arterial hypertension (n = 376, 47.78%) and hypercholesterolemia (n = 345, 43.84%). Most non-AF/AFL SLE patients had 0–1 points in the CHA₂DS₂-VA score (n = 514, 65.31%). Overall, ischemic stroke occurred in 47 cases during a median follow-up of 8 (4–17) years regarding time from the SLE diagnosis to the stroke, with the incidence rising from 0% (n = 0/297) to 28% (n = 14/50) as the CHA₂DS₂-VA score increased from 0 to ≥5 points. No ischemic strokes or other thromboembolic events occurred among the 575 (73.06%) patients with a CHA₂DS₂-VA score of 0–2 points. In the whole cohort, patients with ≥3 points in the CHA₂DS₂-VA score (n = 212, 26.94%) were older at the last visit, had longer disease duration, were more commonly of the male sex, and were diagnosed more frequently with ischemic stroke or other thromboembolic events in their medical history (p < 0.05, for all) compared to those with 0–2 points (n = 575, 73.06%). However, in multivariable logistic regression, among the CHA₂DS₂-VA components, only older age (≥50 years) was related to the increased risk of thromboembolic complications (OR = 2.09, 95% CI: 1.36–3.22). Other determining factors included the presence of lupus anticoagulant (OR = 3.39, 95% CI: 2.20–5.27) and neurological SLE symptoms (OR = 2.19, 95% CI: 1.19–4.02). Interestingly, male sex (OR = 0.34, 95% CI: 0.22–0.52) and general SLE symptoms (OR = 0.43, 95% CI: 0.28–0.67) were associated with a decreased risk of thromboembolic events in this model (p = 0.034, for the model). Conclusions: SLE-related factors seem important for the onset of thromboembolic episodes. However, a higher CHA₂DS₂-VA score may also help to identify SLE patients with an increased risk of cardiovascular events, including stroke. Prospective studies with a long-term analysis need to be validated using the CHA₂DS₂-VA score to predict stroke risk in SLE patients. Full article

This paper presents an analysis of helminth diversity in reptiles in eight provinces of the Middle Volga region (European Russia) based on the dataset recently published in the GBIF as the Darwin Core Archive. The dataset contains up-to-date information on the occurrence of parasitic worms in lizards and snakes and summarizes the records obtained during long-term helminthological studies conducted in 1996–2024. It includes 8576 helminth occurrence records in nine reptile species inhabiting the Middle Volga region. All helminth occurrence records are georeferenced. In total, we present data on 45 parasitic worm species, including 4 species of cestodes, 21 species of trematodes, 16 species of nematodes, and 4 species of acanthocephalans. The richest helminth fauna was found in Natrix natrix (26 species), Lacerta agilis (21), Natrix tessellata (16), and Vipera berus (15). Less diverse is the helminth fauna in Anguis colchica (8 species), Zootoca vivipara (7), Vipera renardi (6), Coronella austriaca (5), and Eremias arguta (3). The diversity of helminths in reptiles of the Middle Volga region does not reach its maximum compared to other European countries. Most helminth species found in lizards and snakes of the studied region belong to the Palearctic faunal complex (25 species). Eight species of parasites have a Holarctic distribution. Seven helminth species parasitize reptiles only in Europe. Five species of parasites are cosmopolitan. Of the 45 species of helminths found in reptiles, 3 species have medical and veterinary significance as causative agents of dangerous helminthiasis. Data on the diversity and distribution of parasitic worms in reptiles of the Middle Volga region remain incomplete, so further observations may provide new occurrence records of helminths and expand the knowledge about their hosts.

Background/Objectives: Inflammatory bowel diseases (IBDs) comprise a group of chronic idiopathic disorders, including ulcerative colitis (UC), Crohn’s disease (CD), and indeterminate colitis (IC). Complex genetic factors, in addition to environmental triggers, have been shown to play a fundamental role in the pathogenesis of IBD, contributing to disease susceptibility. The transition of adolescents with inflammatory bowel disease (IBD) to adult care represents a significant challenge for patients, their families, and healthcare providers. Approximately 25% of individuals with IBD receive a diagnosis before the age of 16, and this population is at increased risk for adverse clinical outcomes. As a result, the transition of care has garnered substantial attention in the scientific and clinical communities over the past decade. This study aims to analyze a cohort of pediatric Sardinian patients with IBD to assess clinical characteristics at diagnosis and at the time of transition and determine potential correlations between NOD2/CARD15 gene variants and HLA class II with the disease phenotype. Methods: From January 2014 to August 2024, we performed an observational, cross-sectional study that included pediatric patients with IBD enrolled in the only pediatric IBD reference center in Sardinia. Data were obtained from the patients’ medical records and from a questionnaire administered at the inclusion visit. In addition, we genotyped a portion of our cohort for the Leu1007fsinsC (SNP13), Gly908Arg (SNP12), and Arg702Trp (SNP8) variants of the NOD2/CARD15 gene, as well as for HLA-DRB1, -DQA1, and -DQB1 class II genes. The obtained results were compared with pediatric data from the national epidemiological IBD registry and existing literature. Results: Seventy-one IBD patients were enrolled (UC 43, CD 28, M 34, F 37). Median age at diagnosis was 12.2 years (IQR 2–17). After a median disease duration of 5 years (IQR: 1–16), only three UC patients experienced proximal extension of proctitis or left-sided colitis, and no CD patients experienced new localizations of disease. Fifteen patients developed extraintestinal manifestations. No significant difference was found in median diagnostic delay (DD) between UC [4 months (IQR: 1–84)] and CD patients [4.5 months (IQR: 1–48)]. At the transition visit, overall, twenty-nine patients (42%) were exposed to one biologic agent (vs. 3% at baseline; p < 0.02); 3 patients (4%) were exposed to two or more biologic agents. 7% of patients (5/71) underwent surgery. By comparing the distribution of NOD2/CARD15 SNPs between pediatric patients and an adult CD population, we found a significant association between gene allelic variants and pediatric onset (p = 0.00048). Our study also revealed a statistically significant association between Sardinian pediatric patients carrying NOD2/CARD15 mutations and early-onset CD (p < 0.009492), along with a stenosing phenotype (p < 0.024) and increased surgical risk (p < 0.026). No significant associations were observed between HLA class II alleles and IBD in our population. Conclusions: Our results provide important insights into the clinical and epidemiological features of the pediatric IBD population. In addition, our study highlights the significant role of NOD2/CARD15 gene polymorphisms in pediatric onset CD. These variants influence the age of onset and disease phenotype, characterized by greater severity and a higher risk of surgical intervention in pediatric patients. Full article

The literature has shown that neonatal deaths contribute largely to the total number of deaths in children under 5 years of age worldwide and that 39% of all neonatal deaths recorded in 2019 were in Africa. Neonatal conditions (NCs) are the main cause of these losses. Therefore, NC research is critical to improve the ability to prevent, predict, detect, treat, and manage neonatal problems. However, this research must be properly funded to arrive at outcomes of interest. Regarding the funding of NC research, no study has addressed this issue. In this regard, a bibliometric analysis of the funding information reported in publications can assist scientists in seeking funds for ongoing or new NC research and those involved in developing and implementing strategies to improve NC funding. Using a bibliometric analysis, this study identified the African and non-African funders mentioned in articles on NC research in Africa published between 1990 and 2019. A set of indicators gives an initial picture of funding activities. The results show that the involvement of African and non-African funders in NC research has increased; NC research is highly dependent on foreign funders, especially from the United States of America (USA) and the United Kingdom (UK); and the funding comes from few funders. Strategies are necessary to reduce the fragility of the funding structure of NC research due to its high dependence on foreign funders and concentration on few funders. Full article

SARS-CoV-2 continues to circulate with new variants of uncertain transmissibility and virulence arising over time and resulting in varying morbidity and mortality between and within countries. This study aimed to identify the predictors of mortality among hospitalized COVID-19 patients across the first five waves of the pandemic. We conducted a retrospective cohort study at Tigoni Level 4 Hospital in Kenya. The study included patients admitted between June 2020 to August 2022 who tested positive for SARS-CoV-2. Sociodemographic and clinical data were abstracted from patient records at the time of admission and throughout their hospital stay. We employed Cox proportional hazard regression analysis to estimate the time to event (discharge or death) and identify predictors of mortality. Both time-varying and non-time-varying covariates were included in the models. A total of 1985 patients were admitted, of whom 557 (28%) died. The median hospital stay was 4 (1.0–8.0) days and 9 (5.0–13.0) days for patients who died and those who were discharged alive, respectively. Compared to patients admitted during wave 1, those admitted during the subsequent waves had high risk of death estimated at adjusted HR: 1.66 (95% CI 1.2, 2.54), 5.17 (95% CI 3.55, 7.53), 2.62 (95% CI 1.87, 3.67), and 2.17 (95% CI 1.51, 3.11) for waves 2, 3, 4, and 5, respectively. A proportion of patients presented with persistent chest pain, cough, and hypoxia and continued oxygen therapy for more than two months. In addition, patients who had persistent fever, hypoxia, cough, and fatigue had a significant mortality risk (adjusted HR: 3.00; 95% CI: 1.81–4.98; HR: 1.97; 95% CI: 1.73–2.26; HR: 1.47; 95% CI: 1.24–1.75; HR: 1.64; 95% CI: 1.05–2.54). Conversely, patients who had low oxygen saturation and received oxygen at admission had a 76% (HR: 0.24; 95% CI: 0.13–0.42) reduction in mortality risk and in addition patients whose treatment was altered had a 49% reduction in mortality risk (HR: 0.51; CI: 0.45–0.58). Our study highlights the benefits of oxygen therapy on the outcome of COVID-19 patients and justifies the need to increase investments in oxygen especially in low-and-middle-income countries. It also confirms the need to analyze the pandemic by the different waves. Full article

Background: It has been demonstrated that levetiracetam can decrease absence epileptic activity in both human patients and different types of animal models of absence epilepsy, such as the genetically absence epileptic Wistar Albino Glaxo/Rijswijk (WAG/Rij) rat. It was also suggested previously that exogenous ketone supplements (EKSs)-evoked ketosis not only decreases the number of spike-wave discharges (SWDs) but also enhances the anti-absence epileptic effect of pyrimidine nucleoside uridine in WAG/Rij rats. These findings suggest that EKSs may enhance the efficacy of clinically used anti-epileptic drugs, such as levetiracetam. Methods: We investigated the effect of not only levetiracetam (intraperitoneal/i.p. 200 mg/kg) alone and KEKS supplemented food (containing 10% ketone ester/KE and 10% ketone salt/KS in a normal rat chow) alone, but also the combination of levetiracetam and KEKS supplemented food on SWD number and SWD time for 5 days in WAG/Rij rats. For evaluation of SWDs, electroencephalographic (EEG) recordings were performed every day. Moreover, for the measurement of blood glucose and R-beta-hydroxybutyrate (R-βHB) levels, the blood was taken from the tail vein of rats after EEG registration. Results: It was demonstrated that the administration of both levetiracetam alone and KEKS food alone decreased the SWD number and time spent in SWD, compared to control. Moreover, after combined administration of levetiracetam with KEKS food, enhanced anti-absence epileptic effect was observed, compared to levetiracetam alone. Blood R-βHB level significantly increased after administration of both KEKS food alone and KEKS food in combination with levetiracetam. Nevertheless, these treatments did not significantly change the blood glucose levels. Conclusions: We can conclude that EKSs may be able to enhance the anti-epileptic effect of different drugs, and this combined treatment method may represent a promising new approach and effective therapy against epileptic seizures, especially in treatment-resistant patients.

The work aims to give a preliminary investigation of the geothermal potentiality of the hot dry granitic rocks in the Hail area, Northern KSA. The Hail area is characterized by a massive exposed belt of radioactive granitic rocks in the southern part, while the northern part is covered by a sedimentary section. A comprehensive methodology utilizing different categories of mineralogical petrographic, geochemical, geophysical well logging and, radiometry datasets, was used to assess the radiogenic heat production capacity of this granite. The measured data are integrated and interpreted to quantify the potential geothermal capacity of the granite and estimate its possible power production. The radioactivity and radiogenic heat production (RHP) of the Hail granites are among the highest recorded values in Saudi Arabia. Land measurements indicate uranium, thorium, potassium, and RHP values of 17.80 ppm, 90.0 ppm, 5.20%, and 11.93 µW/m³, respectively. The results indicated the presence of a reasonable subsurface geothermal reservoir condition with heat flow up to 99.87 mW/M² and a reservoir temperature of 200 °C (5 km depth). Scenarios for energy production through injecting water and high-pressure CO₂ in the naturally/induced fractured rock are demonstrated. Reserve estimate revealed that at a 2% heat recovery level, the Hail granites could generate about 3.15 × 10¹⁶ MWe, contributing to an average figure of 3.43 × 10¹² kWh/y, for annual energy per capita Saudi share. The results of this study emphasized the potential contribution of the Hail granite in the future of the energy mix of KSA, as a new renewable and sustainable resource. It is recommended to enhance the surface geophysical survey in conjunction with a detailed thermo-mechanical laboratory investigation to delineate the subsurface orientation and geometry of the granite and understand its behavior under different temperature and pressure conditions.

Blood Flow Restriction Training (BFRT) is a training method typically performed with low-intensity loads, yet it has been shown to induce muscle growth and strength gains similar to those achieved through high-load resistance training. This study investigates how different cuff widths affect muscle activation and synergy during squat exercises under BFRT conditions, using wavelet packet transform combined with non-negative matrix factorization (WPT-NNMF) for time-frequency analysis of muscle synergy. Fifteen male participants, each with more than three years of resistance training experience, performed squats under three conditions: non-BFRT (Non-BFRT), BFRT with a 5 cm cuff (5 cm-BFRT), and BFRT with a 10 cm cuff (10 cm-BFRT), all at 30% of their one-repetition maximum (1RM). Surface electromyography (sEMG) signals were recorded from eight lower-limb muscles, and muscle synergy patterns were analyzed using NNMF and WPT-NNMF. The results showed that, compared to Non-BFRT, the 10 cm-BFRT condition significantly increased activation in the vastus lateralis (VL), gluteus maximus (GM), tibialis anterior (TA), and lateral gastrocnemius (GL), while the 5 cm-BFRT decreased activation in the biceps femoris (BF) and increased TA activation. Muscle synergy analysis revealed three distinct synergy modules across all conditions, with the total number of synergies remaining stable. However, the activation weights of muscles within these modules varied across different squat phases, suggesting adaptive neuromuscular regulation under different BFRT conditions. The time-frequency synergy analysis highlighted dynamic changes in muscle coordination across time scales and frequency bands under various training conditions. The number of muscle synergies showed significant changes across different time-frequency regions, with a marked decrease in the 120–250 Hz frequency range in the 5 cm-BFRT condition compared to Non-BFRT. This study is the first to apply time-frequency muscle synergy analysis to investigate the effects of cuff width on neuromuscular coordination during BFRT. The findings offer new insights into the time-frequency characteristics of muscle synergy under BFRT conditions and enhance the understanding of neuromuscular control and motor execution in blood flow restriction training.

In this study, a reliable and efficient micropropagation protocol was developed for Stachys byzantina, a valuable and promising ornamental species. For the initial in vitro cultures on the Murashige and Skoog (MS) medium, shoot tips were used as explants. The addition of 5 μM of kinetin (KIN) resulted in the production of multiple (6.0 shoots/explant) and elongated (3.6 cm) shoots. The MS medium supplemented with 10 μM of a-Naphthaleneacetic acid (NAA) proved efficient for the in vitro rooting (73.3%) of the microshoots. For the ex vitro rooting of the microshoots, the treatment with 0.5 g L⁻¹ of Indole-3-butyric acid potassium salt (K-IBA), before planting in 1:1 (v/v) peat and perlite substrate and placed in a fog system, led to 86.7% rooting. The acclimatization stage was successful, and 96.7% survival was recorded for the ex vitro-rooted plantlets. Inter Simple Sequence Repeat (ISSR) markers were employed to examine the genetic uniformity of the in vitro-derived plantlets with the mother S. byzantina plants. The monomorphic banding pattern in the micropropagated plants and the mother plant confirmed the genetic uniformity of the in vitro-derived plantlets and revealed the reliability of the proposed in vitro protocol for S. byzantina. As far as we know, this is the first study on a combined micropropagation and genetic uniformity assessment of the species, the findings of which could be further used to apply new in vitro cultivation techniques or to produce elite genotypes of S. byzantina.
