Oxidative stress in follicular fluid of young women with low response compared with fertile oocyte donors.

The aim of this study was to determine the concentrations of oxidative stress markers, antioxidant enzymes and cytokines in the follicular fluid of young women with low response in ovarian stimulation cycles compared with high responders and fertile oocyte donors of the same age, to assess the impact of oxidative stress on ovarian reserve. The activity of follicular fluid antioxidant enzymes glutathione transferase, glutathione reductase and glutathione peroxidase was significantly lower in young women with reduced ovarian reserve compared with that in high responders and oocyte donors. Follicular fluid concentrations of oxidative stress marker malondialdehyde combined with 4-hydroxyalkenals and nitric oxide were higher in low responders than in high responders and oocyte donors. Significant differences between low responders and donors in concentrations of IL-2, IL-6, IL-8 and vascular endothelial growth factor were observed, with higher concentrations in low responders. However, IL-10 concentration was lower in low responders than in high responders and donors. No significant differences were found in follicular fluid concentrations of tumour necrosis factor alpha between the three groups. These results demonstrate that different concentrations of oxidative stress markers, oxidant enzymes and cytokines in low responders compared with high responders and oocyte donors may negatively impact ovarian response.

[LIMB SHAKING: DESCRIPTION OF A CASE FROM A NURSING PERSPECTIVE]. / Limb shaking: DESCRIPCIÓN DE UN CASO DESDE LA PERSPECTIVA ENFERMERA.

INTRODUCTION: Limb shaking, which was described by MillerFisher in 1962, is characterized by involuntary, irregular, stereotyped a hemibody triggered by the contralateral hemisphere hypoperfusion. It is associated with an occlusion or stenosis preoclusive of the extracranial internal carotid artery (ICA) contralateral to the movements, and poor circulation contralateral. This causes ischemia resulting in typical clinical manifestations of stroke and these abnormal movements. OBJECTIVE: To describe a case of limb shaking. MATERIALS AND METHODS: 59 years old man, with cardiovascular risk factors, who go to the Emergency room with symptoms and motor dysphasia and sudden loss of strength in right limbs, with distal brachial predominance. Admitted to Stroke Unit for neurological and hemodynamic monitoring, which coincides with the beginning of the sitting have an episode of these involuntary movements. RESULTS: Diagnostic tests confirm a left frontal cortical ischemic stroke. The EEG shows a normal background bioelectric activity. The angio-MRI and angiography showed a left ICA pseudoocclusion. DISCUSSON: A diagnosis of limb shaking based in the clinical examination and additional tests, which confirm the finding of a left ICA pseudo-occlusion and refractory to antiepileptic treatment. CONCLUSION: The limb shaking is a rare syndrome, which must be recognized and differentiated early from other processes to treat it properly. Treatment is aimed at restoring cerebral blood flow through the ischemic hemisphere revascularization.

Physicochemical Characterisation of Seeds, Oil and Defatted Cake of Three Hempseed Varieties Cultivated in Spain.

The increasing use of hempseed in food products highlights the need for a comprehensive database for scientific research and industrial applications. In food development, information about the techno-functional properties of raw materials plays a crucial role in determining the suitability of each product for specific applications. Thus, this study aims to characterise three hempseed varieties (Ferimon, Henola and Uso-31), comparing their physicochemical and nutritional compositions. Moreover, the study investigates the impact of hempseed varieties on the techno-functional, physical and thermal properties of the partially defatted hempseed flours (PDHFs) obtained from single screw pressing (SSP) oil extraction. The fatty acid and tocopherol profiles of the dehulled seeds and oil were also analysed. Significant variations in yield and physical properties were observed among hempseed varieties, influenced by genetics, adaptation to agro-climatic conditions and cultivation systems. Despite its lower yield (kg/ha), Uso-31 exhibited superior 1000-seed weight, dehulling yield and larger mean seed size (1.79 ± 0.02 mm). Hempseed oil was rich in unsaturated fatty acids, particularly linoleic (51.2-53.4 g/100 g oil) and α-linolenic (14.88-18.97 g/100 oil) acids, showing variations in γ- and α-tocopherols depending on the variety. The variety also influenced the least gelation concentration (LGC) and techno-functional properties such as water absorption capacity (WAC), emulsifying activity (EA) and emulsion stability (ES). SDS-PAGE and DSC measurements indicated the presence of 11S and 7S globulin proteins with denaturation temperatures above 87.8 °C. These findings confirm that the studied hempseed flours are valuable techno-functional and nutritional ingredients suitable for sustainable food formulations.

From 'Farm to Fork': Exploring the Potential of Nutrient-Rich and Stress-Resilient Emergent Crops for Sustainable and Healthy Food in the Mediterranean Region in the Face of Climate Change Challenges.

In the dynamic landscape of agriculture and food science, incorporating emergent crops appears as a pioneering solution for diversifying agriculture, unlocking possibilities for sustainable cultivation and nutritional bolstering food security, and creating economic prospects amid evolving environmental and market conditions with positive impacts on human health. This review explores the potential of utilizing emergent crops in Mediterranean environments under current climate scenarios, emphasizing the manifold benefits of agricultural and food system diversification and assessing the impact of environmental factors on their quality and consumer health. Through a deep exploration of the resilience, nutritional value, and health impacts of neglected and underutilized species (NUS) such as quinoa, amaranth, chia, moringa, buckwheat, millet, teff, hemp, or desert truffles, their capacity to thrive in the changing Mediterranean climate is highlighted, offering novel opportunities for agriculture and functional food development. By analysing how promoting agricultural diversification can enhance food system adaptability to evolving environmental conditions, fostering sustainability and resilience, we discuss recent findings that underscore the main benefits and limitations of these crops from agricultural, food science, and health perspectives, all crucial for responsible and sustainable adoption. Thus, by using a sustainable and holistic approach, this revision analyses how the integration of NUS crops into Mediterranean agrifood systems can enhance agriculture resilience and food quality addressing environmental, nutritional, biomedical, economic, and cultural dimensions, thereby mitigating the risks associated with monoculture practices and bolstering local economies and livelihoods under new climate scenarios.

Implementation of a virtual community of practice to promote the empowerment of middle-aged people with multimorbidity: study protocol of a randomised controlled trial.

INTRODUCTION: Empowering people living with multimorbidity (multiple chronic conditions) to gain greater confidence in managing their health can enhance their quality of life. Education focused on self-management is a key tool for fostering patient empowerment and is mostly provided on an individual basis. Virtual communities of practice (VCoP) present a unique opportunity for online education in chronic condition self-management within a social context. This research aims to evaluate the effectiveness/cost-effectiveness of individualised, online self-management education compared with VCoP among middle-aged individuals living with multiple chronic conditions. METHODS AND ANALYSIS: People aged 30-60, living with ≥2 chronic conditions and receiving care in primary care (PC) centres and outpatient hospital-based clinics in Madrid and Canary Islands will enrol in an 18-month parallel-design, blinded (intervention assessment and data analysts), pragmatic (adhering to the intention-to-treat principle), individually randomised trial. The trial will compare two 12-month web-based educational offers of identical content; one delivered individually (control) and the other with online social interaction (VCoP, intervention). Using repeated measures mixed linear models, with the patient as random effect and allocation groups and time per group as fixed effects, we will estimate between-arm differences in the change in Patient Activation Measure from baseline to 12 months (primary endpoint), including measurements at 6-month and 18-month follow-up. Other outcomes will include measures of depression and anxiety, treatment burden, quality of life. In addition to a process evaluation of the VCoP, we will conduct an economic evaluation estimating the relative cost-effectiveness of the VCoP from the perspectives of both the National Health System and the Community. ETHICS AND DISSEMINATION: The trial was approved by Clinical Research Ethics Committees of Gregorio Marañón University Hospital in Madrid/Nuestra Señora Candelaria University Hospital in Santa Cruz de Tenerife. The results will be disseminated through workshops, policy briefs, peer-reviewed publications and local/international conferences. TRIAL REGISTRATION NUMBER: NCT06046326.

Recurrent transient ischaemic attack and early risk of stroke: data from the PROMAPA study.

BACKGROUND: Many guidelines recommend urgent intervention for patients with two or more transient ischaemic attacks (TIAs) within 7 days (multiple TIAs) to reduce the early risk of stroke. OBJECTIVE: To determine whether all patients with multiple TIAs have the same high early risk of stroke. METHODS: Between April 2008 and December 2009, we included 1255 consecutive patients with a TIA from 30 Spanish stroke centres (PROMAPA study). We prospectively recorded clinical characteristics. We also determined the short-term risk of stroke (at 7 and 90 days). Aetiology was categorised using the TOAST (Trial of Org 10172 in Acute Stroke Treatment) classification. RESULTS: Clinical variables and extracranial vascular imaging were available and assessed in 1137/1255 (90.6%) patients. 7-Day and 90-day stroke risk were 2.6% and 3.8%, respectively. Large-artery atherosclerosis (LAA) was confirmed in 190 (16.7%) patients. Multiple TIAs were seen in 274 (24.1%) patients. Duration <1 h (OR=2.97, 95% CI 2.20 to 4.01, p<0.001), LAA (OR=1.92, 95% CI 1.35 to 2.72, p<0.001) and motor weakness (OR=1.37, 95% CI 1.03 to 1.81, p=0.031) were independent predictors of multiple TIAs. The subsequent risk of stroke in these patients at 7 and 90 days was significantly higher than the risk after a single TIA (5.9% vs 1.5%, p<0.001 and 6.8% vs 3.0%, respectively). In the logistic regression model, among patients with multiple TIAs, no variables remained as independent predictors of stroke recurrence. CONCLUSIONS: According to our results, multiple TIAs within 7 days are associated with a greater subsequent risk of stroke than after a single TIA. Nevertheless, we found no independent predictor of stroke recurrence among these patients.

Cerebral hemodynamic changes in obstructive sleep apnea syndrome after continuous positive airway pressure treatment.

BACKGROUND: Patients with obstructive sleep apnea syndrome (OSAS) are at increased risk for cerebrovascular diseases. The underlying mechanisms remain obscure. It may occur through a reduction in cerebral vascular reactivity. Continuous positive airway pressure (CPAP) is effective in reducing the occurrence of apneas. We hypothesized that treatment with CPAP improves cerebral vascular reactivity. METHODS: This is a prospective study with OSAS patients. The apnea test (ApT) was calculated as an increase of mean artery velocity during apnea: [Artery velocity in apnea minus Resting artery velocity]/Resting artery velocity expressed as percentage. After 2 years of CPAP treatment, the test was repeated. RESULTS: Seventy-six patients represented the study pool. After 2 years of treatment with CPAP, we were able to conduct a reassessment in 65 patients. Of the 65 patients who finished the clinical study, 56 were men, and 9 were women, with an average age of 48.1 ± 10.4 years. There was an improvement in the ApT after CPAP treatment (30.8 ± 12.1 vs 39.8 ± 15.1; p:0.000). The values of cerebral blood flow velocities, diastolic blood pressure in apnea, and basal heart rate decreased. CONCLUSIONS: Cerebral vascular reactivity in OSAS patients measured by ApT improved after 2 years of CPAP.

Cerebral hemodynamic changes at basilar artery in obstructive sleep apnea syndrome after continuous positive airway pressure treatment.

BACKGROUND: Cerebral vasoreactivity in obstructive sleep apnea syndrome is altered. Continuous positive airway pressure is effective in the reduction of the occurrence of apneas. We studied whether this treatment also improves cerebral vasoreactivity. METHODS: The breath-holding maneuver was performed and assessed by apnea test with transcranial Doppler in the basilar artery. After 2 years of continuous positive airway pressure treatment, the test was repeated. RESULTS: There is an improvement in the apnea test after continuous positive airway pressure. There are increases in the pulsatility index, diastolic blood pressure, and basal heart rate. The improvement in the apnea test depends on the body mass index of the patient. CONCLUSIONS: Cerebral vasoreactivity as measured by the apnea test improves after 2 years of continuous positive airway pressure. This improvement depends of the body mass index of the patient.

Charlson comorbidity index in ischemic stroke and intracerebral hemorrhage as predictor of mortality and functional outcome after 6 months.

BACKGROUND: The Charlson Comorbidity Index (CCI) is commonly used in outcome and mortality studies. Our aim was to investigate the association between CCI score and the functional outcome and mortality 6 months after ischemic stroke (IS) or intracerebral hemorrhage. METHODS: This was a prospective observational cohort of patients with spontaneous intracerebral hemorrhage and IS admitted to the stroke unit during 18 months. The modified Rankin scale (mRS) score was obtained for subjects 6 months after event. The CCI score was dichotomized (low comorbidity 0 or 1 versus high ≥ 2) for analysis. The mRS score was also dichotomized (good outcome, mRS score 0 or 1 versus poor outcome, mRS score ≥ 2). RESULTS: In all, 175 patients were enrolled in the study. Logistic regression showed that those with a high CCI score (≥ 2) had 37.3% increased odds of having a poor outcome (≥ 2) at 6 months and 68.4% greater odds of death at 6 months. CONCLUSIONS: Comorbid medical conditions independently influence outcome after IS or intracerebral hemorrhage.

Influence of maize flour particle size on gluten-free breadmaking.

BACKGROUND: Maize, one of the suitable grains for coeliac consumption, is, together with rice, the most cultivated cereal in the world. However, the inclusion of maize flour in gluten-free bread is a minority and studies are scarce. This paper analyses the influence of different maize flour types and their particle sizes on the quality of two types of bread without gluten (80% and 110% water in the formulation) obtained from them. We also analysed the microstructure of the dough and its behaviour during the fermentation. RESULTS: Finer flours had a lower dough development during fermentation in all cases. Among the different types of flour, those whose microstructure revealed compact particles were those which had higher specific bread volume, especially when the particle size was greater. Among the formulations, the dough with more water gave breads with higher specific volume, an effect that was more important in more compact flours. The higher volume breads had lower values of hardness and resilience. CONCLUSION: The type of corn flour and mainly its particle size influence significantly the dough development of gluten-free bread during fermentation and therefore the final volume and texture of the breads obtained. The flours having coarser particle size are the most suitable for making gluten-free maize bread.

Peripheral endothelial function and arterial stiffness in patients with chronic migraine: a case-control study.

BACKGROUND: Migraine is a complex and disabilitating neurovascular disorder predominantly affecting women. There is strong evidence that nitric oxide is critically involved in migraine pathophysiology. The aim of the present study was to test the hypothesis that chronic migraine is associated with ultrasonographic endothelial dysfunction and increase in arterial stiffness. These parameters were assessed using a novel plethysmograph by peripheral arterial tonometry. METHODS: Twenty-one patients with chronic migraine and twenty-one healthy controls matched by sex and gender were recruited. Measurement of the ultrasonographic endothelial function and augmentation index were made according to manufacturer's protocol. RESULTS: The mean of patient's peripheral arterial tonometry ratios was 1.93 ± 0.39 and for healthy control 2.21 ± 0.44 (p=0.040). The median of patients' augmentation index was -6,0 (IQR: 6.5 to -15) in healthy controls and 9.0 (IQR: 4 to 12) in chronic migraine, (p=0.002). CONCLUSIONS: Patients with chronic migraine have ultrasonographic endothelial dysfunction and increase in the arterial stiffness. An improved understanding of the role in the endothelial system of migraine may provide a basis for preventive drugs in migraine and restore the endothelial function.

Microwave Modification of Quinoa Grains at Constant and Varying Water Content Modulates Changes in Structural and Physico-Chemical Properties of the Resulting Flours.

Microwave-assisted heat moisture treatment (MWT) was applied to quinoa grains, a nutritious gluten-free pseudocereal of great interest in food product development, to achieve the physical modification of the quinoa flour. The effect of treating quinoa grains at different initial water contents (WC; 10%, 20%, and 30%) in two operational systems was compared: one open at atmospheric pressure and variable WC (V system), and the other in hermetic containers at constant WC (C system). The morphological structure of the obtained flours and their techno-functional, rheological, and thermal properties were evaluated. MWT proved to be effective in modifying these properties, the main effects probably being caused by protein denaturation and aggregation, and intragranular molecular rearrangements of starch, with disruption of short-range molecular order and even the partial collapse of starch granules in the samples treated at the highest WC. The greatest differences were observed for the 20 and 30% WC treated-samples, particularly when using C system, which increased their water absorption capacity and decreased their foaming, emulsion, and gel-forming capacities. Based on these results, the control of WC and its evolution during MWT of quinoa grains appears to be a viable and effective approach to adapt flour functionality to the needs of food production, allowing a wider range of flour properties depending on the MWT conditions.

The Application of High-Hydrostatic-Pressure Processing to Improve the Quality of Baked Products: A Review.

The current trend in the food industry is towards "clean label" products with high sensory and nutritional quality. However, the inclusion of nutrient-rich ingredients in recipes often leads to sensory deficiencies in baked goods. To meet these requirements, physically modified flours are receiving more and more attention from bakery product developers. There are various findings in the literature on high hydrostatic pressure (HHP) technology, which can be used to modify various matrices so that they can be used as ingredients in the baking industry. HHP treatments can change the functionality of starches and proteins due to cold gelatinization and protein unfolding. As a result, the resulting ingredients are more suitable for nutrient-rich bakery formulations. This review describes the information available in the literature on HHP treatment conditions for ingredients used in the production of bakery products and analyses the changes in the techno-functional properties of these matrices, in particular their ability to act as structuring agents. The impact of HHP-treated ingredients on the quality of dough and bakery products and the effects on some nutritional properties of the treated matrices have been also analysed. The findings presented in this paper could be of particular interest to the bakery industry as they could be very useful in promoting the industrial application of HHP technology.

Valorisation of Buckwheat By-Product as a Health-Promoting Ingredient Rich in Fibre for the Formulation of Gluten-Free Bread.

Bread is a widely consumed food that has often been used as a vehicle for functional ingredients such as dietary fibre. Fibre-rich breads have beneficial physiological effects on health, helping to combat chronic pathologies such as cardiovascular disease, diabetes, and certain types of colon cancer. The aim of this study is to evaluate the technological and nutritional effects of the inclusion of buckwheat hull particles (BH) at two addition levels (3 and 6%) and two particle sizes (fine, D50: 62.7 µm; coarse, D50: 307 µm) in a gluten-free (GF) bread formulation. A significant (p < 0.05) increase in the dough elastic modulus (G') was observed for all doughs containing BH, from 712 Pa for a rice-based dough to 1027-3738 Pa for those containing BH. Compared to rice-based breads, those containing BH showed a significant (p < 0.05) increase in total dietary fibre content (from three to five times) and in antioxidant capacity (from 78 to 290 mg TE/100 g dw. in the ORAC test). Breads containing fine BH at a level of 3% had similar sensory properties to the rice-based bread, demonstrating that it is possible to improve the TDF content while maintaining the sensory quality of the GF bread.

High insoluble fibre content increases in vitro starch digestibility in partially baked breads.

Wheat breads prepared from frozen partially baked breads were characterized by their content of rapidly digestible starch (RDS) and slowly digestible starch (SDS) by the in vitro starch digestibility method developed by Englyst. Breads with different contents and types of fibre and breads prepared with different fermentation processes were studied. Bread with inulin and with a double fermentation had the lowest RDS content of 58.8 ± 1.7 and 60.0 ± 1.9 (% dry matter), respectively. Wheat bran bread, seeded bread, triple fermentation white bread and baguette-type bread showed values of RDS between 63.1 ± 1.7 and 65.7 ± 1.7 with no significant differences between them (p < 0.05). The fraction of SDS was higher in wheat breads than in breads with added fibre. The highest values of the starch digestive rate index (SDRI) were obtained by the three types of breads with added fibre, which ranged from 91.8 ± 3.5 to 95.8 ± 3.5 versus 80.2 ± 3.5 to 87.5 ± 3.5 for white wheat breads. A significant (p < 0.01) positive linear correlation between the insoluble fibre content and SDRI was obtained (R² = 0.96). Insoluble fibre dilutes and disrupts gluten network and probably weakens the interaction between gluten and starch, which protects starch from digestive enzymes action. Scanning electronic microscopy microstructure of bread crumbs corroborated this statement.

Relationships between lipids levels in blood plasma, follicular fluid and seminal plasma with ovarian response and sperm concentration regardless of age and body mass index.

PURPOSE: There is a considerable literature supporting the role of lipids in fertility. However, little is known about their impact on male and female gametes. Our study aimed to investigate the relationships between lipids levels in serum, follicular fluid and seminal plasma with ovarian response and sperm concentration regardless of age and body mass index (BMI). METHODS: 51 follicular fluid and serum samples of IVF-ICSI cycles and 52 seminal plasma and serum samples of males in the infertility study were analyzed for cholesterol, triglycerides, and non-esterified fatty acids. The parameters used to assess gonadal response were number of mature oocytes in metaphase II and total motile sperm. Differences between groups were studied by means Principal Component Analysis, Kolmogorov-Smirnov test, Pearson correlation, Student's T, and multivariate linear regression. RESULTS: Using a multivariate linear regression model to exclude the effect of the age and BMI, we found that the lipid profile in follicular fluid and plasma influence inversely and significantly on ovarian response and the number of matured oocytes recovered. Moreover, we found that seminal lipid levels are predictors of seminal quality independent of plasma lipid values. CONCLUSION: Our current analysis demonstrates the association of low ovarian response and low number of motile sperms with abnormal lipids levels.

Arboreal camera trapping sheds light on seed dispersal of the world's only epiphytic gymnosperm: Zamia pseudoparasitica.

Epiphytic lifestyles have evolved independently in ecologically, morphologically, and taxonomically diverse plant species. Although this adaptation is widespread among angiosperms, it is only known to have arisen in a single gymnosperm species, Zamia pseudoparasitica (Cycadophyta). Zamia pseudoparasitica is endemic to the mountains of Western Panama, and little is known about the ecology of this unusual cycad. Here, we provide the first report of a potential seed disperser of Z. pseudoparasitica. Between late October 2019 and March 2020, we conducted arboreal camera trapping at three sites along the Talamanca Cordillera in Western Panama, yielding an accumulated survey effort of 271 camera days. Weekly direct observations were also performed using handheld binoculars at one site. Arboreal camera trapping revealed at least seven mammal species that visit this epiphytic cycad. At all three sites, the Northern olingo (Bassaricyon gabbii) was seen visiting individuals of Z. pseudoparasitica repeatedly, both while cones were closed and after they had opened. We estimated the time-varying intensity of the visits throughout our sampling and used mixed models to compare the length of visits when cones were closed versus when they were open. Both duration and time-varying intensity of visits increased after cones had opened and we documented Northern olingo removing and carrying away seeds. We also observed predation by the yellow-eared toucanet (Selenidera spectabilis) which picked and destroyed mature Z. pseudoparasitica seeds. These results suggest that the Northern olingo could be an important seed dispersal agent for this rare epiphytic gymnosperm.

Common carotid artery aneurysm revealing Takayasu's arteritis.

Takayasu's arteritis (TA) is a chronic inflammatory disease of unknown etiology affecting large vessels, most markedly the aorta and its branches. Stroke or transient ischemic attack may occur in TA due to either the occlusion or embolic material originating from the inflammatory region of the vessel. Extracranial carotid aneurysms caused by TA are extremely rare and usually appear at advanced stages of the disease. A 27-year-old woman presented with carotidynia and a left laterocervical mass. Ultrasonography of the bilateral carotid arteries revealed an aneurysm of the left common carotid artery. The patient fulfilled the diagnostic criteria for TA. Extracranial carotid artery aneurysm could be an initial manifestation of this disease. The diagnosis of TA was made on the basis of the presence of systemic inflammatory reaction and the anatomic locations of the affected arteries-the common carotid artery in a young woman. Surgery with stent placement can be a successful long-term treatment.

Short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) secondary to epidermoid cyst in the right cerebellopontine angle successfully treated with surgery.

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) syndrome is a rare headache syndrome classified among the trigeminal autonomic cephalalgias. It is usually idiopathic, although infrequent secondary forms have been described. Recently, the term short-lasting unilateral headache with cranial autonomic symptoms (SUNA) has been defined by the International Headache Society (ICHD-2) as similar to SUNCT with less prominent absent conjunctival injection and lacrimation. We report a patient with paroxysmal orbito-temporal pains, phenotypically suggesting SUNA, secondary to epidermoid cyst in the cerebellopontine angle which disappeared after tumor resection. Neuroimaging should be considered in all patients with SUNA, notably in those with atypical presentation as our patient who presented on examination trigeminal hypoesthesia and tinnitus. Realization of a brain MRI would rule out injuries that causes this type of syndrome.

Assessment of Maternal Effects and Genetic Variability in Resistance to Verticillium dahliae in Olive Progenies.

The use of genetic resistance is likely the most efficient, economically convenient and environmentally friendly control method for plant diseases, as well as a fundamental piece in an integrated management strategy. This is particularly important for woody crops affected by diseases in which mainly horizontal resistance mechanisms are operative, such as Verticillium wilt, caused by Verticillium dahliae. In this study, we analyzed the variability in resistance to Verticillium wilt of olive trees in progenies from five crosses: 'Picual' × 'Frantoio', 'Arbosana' × 'Koroneiki', 'Sikitita' × 'Arbosana', 'Arbosana' × 'Frantoio' and 'Arbosana' × 'Arbequina' and their respective reciprocal crosses. Additionally, seedlings of 'Picual' and 'Frantoio' in open pollination were used as controls. In October 2016 and 2018, the fruits were harvested, and seeds germinated. Six-week-old seedlings were inoculated by dipping their bare roots in a conidial suspension of V. dahliae, and disease progress in terms of symptom severity and mortality was evaluated weekly. Additionally, seedling growth was evaluated every two weeks. At the end of the experiment, no significant differences were found for any of the assessed parameters when reciprocal crosses were compared. These results suggest that there is no maternal or paternal effect in regard to the heritability of resistance. In addition, this study identifies the best crosses for obtaining the highest number of resistant genotypes, highlighting the importance of the selection of specific cultivars to optimize the breeding process.
