Abstract
BACKGROUND Although germline BRCA mutations have been associated with adverse outcomes in prostate cancer (PC), understanding of the association between somatic/germline alterations in homologous recombination repair (HRR) genes and treatment outcomes in metastatic castration-resistant PC (mCRPC) is limited. The aim of this study was to investigate the prevalence and outcomes associated with somatic/germline HRR alterations, particularly BRCA1/2, in patients initiating first-line (1L) mCRPC treatment with androgen receptor signalling inhibitors (ARSi) or taxanes. PATIENTS AND METHODS Data from 729 mCRPC patients were pooled for CAPTURE from four multicentre observational studies. Eligibility required 1L treatment with ARSi or taxanes, adequate tumour samples and biomarker panel results. Patients underwent paired normal and tumour DNA analyses by next-generation sequencing using a custom gene panel including ATM, BRCA1, BRCA2, BRIP1, CDK12, CHEK2, FANCA, HDAC2, PALB2, RAD51B and RAD54L. Patients were divided into subgroups based on somatic/germline alteration(s): with BRCA1/2 mutations (BRCA); with HRR mutations except BRCA1/2 (HRR non-BRCA); and without HRR alterations (non-HRR). Patients without BRCA1/2 mutations were classified as non-BRCA. Radiographic progression-free survival (rPFS), progression-free survival 2 (PFS2) and overall survival (OS) were assessed. RESULTS Of 729 patients, 96 (13.2%), 127 (17.4%) and 506 (69.4%) were in the BRCA, HRR non-BRCA and non-HRR subgroups, respectively. BRCA patients performed significantly worse for all outcomes than non-HRR or non-BRCA patients (P < 0.05), while PFS2 and OS were significantly shorter for BRCA than HRR non-BRCA patients (P < 0.05). HRR non-BRCA patients also had significantly worse rPFS, PFS2 and OS than non-HRR patients. Exploratory analyses suggested that for BRCA patients, there were no significant differences in outcomes associated with 1L treatment choice (ARSi or taxanes) or with the somatic/germline origin of the alterations. CONCLUSIONS Worse outcomes were observed for mCRPC patients in the BRCA subgroup compared with non-BRCA subgroups, either HRR non-BRCA or non-HRR. Despite its heterogeneity, the HRR non-BRCA subgroup presented worse outcomes than the non-HRR subgroup. Screening early for HRR mutations, especially BRCA1/2, is crucial in improving mCRPC patient prognosis.

Abstract
The carbonation of alkaline industrial wastes is a pressing issue that is aimed at reducing CO2 emissions while promoting a circular economy. In this study, we explored the direct aqueous carbonation of steel slag and cement kiln dust in a newly developed pressurized reactor that operated at 15 bar. The goal was to identify the optimal reaction conditions and the most promising by-products that can be reused in their carbonated form, particularly in the construction industry. We proposed a novel, synergistic strategy for managing industrial waste and reducing the use of virgin raw materials among industries located in Lombardy, Italy, specifically Bergamo-Brescia. Our initial findings are highly promising, with argon oxygen decarburization (AOD) slag and black slag (sample 3) producing the best results (70 g CO2/kg slag and 76 g CO2/kg slag, respectively) compared with the other samples. Cement kiln dust (CKD) yielded 48 g CO2/kg CKD. We showed that the high concentration of CaO in the waste facilitated carbonation, while the presence of Fe compounds in large amounts caused the material to be less soluble in water, affecting the homogeneity of the slurry.

Abstract
Thermochromic dynamic cool materials present a reversible change of their properties wherein by increasing the temperature, the reflectance, conductivity, and transmittance change due to a reversible crystalline phase transition. In particular, vanadium (IV) dioxide shows a reversible phase transition, accompanied by a change in optical properties, from monoclinic VO2(M1) to tetragonal VO2(R). In this paper, we report on a systematic exploration of the parameters for the synthesis of vanadium dioxide VO2(M1) via an easy, sustainable, reproducible, fast, scalable, and low-cost hydrothermal route without hazardous chemicals, followed by an annealing treatment. The metastable phase VO2(B), obtained via a hydrothermal route, was converted into the stable VO2(M1), which shows a metal–insulator transition (MIT) at 68 °C that is useful for different applications, from energy-efficient smart windows to dynamic concrete. Within this scenario, a further functionalization of the oxide nanostructures with tetraethyl orthosilicate (TEOS), characterized by an extreme alkaline environment, was carried out to ensure compatibility with the concrete matrix. Structural properties of the synthesized vanadium dioxides were investigated using temperature-dependent X-ray Diffraction analysis (XRD), while compositional and morphological properties were assessed using Scanning Electron Microscopy, Energy Dispersive X-ray Analysis (SEM-EDX), and Transmission Electron Microscopy (TEM). Differential Scanning Calorimetry (DSC) analysis was used to investigate the thermal behavior.

Abstract
We present a mean-field formalism able to predict the collective dynamics of large networks of conductance-based interacting spiking neurons. We apply this formalism to several neuronal models, from the simplest Adaptive Exponential Integrate-and-Fire model to the more complex Hodgkin-Huxley and Morris-Lecar models. We show that the resulting mean-field models are capable of predicting the correct spontaneous activity of both excitatory and inhibitory neurons in asynchronous irregular regimes, typical of cortical dynamics. Moreover, it is possible to quantitatively predict the population response to external stimuli in the form of external spike trains. This mean-field formalism therefore provides a paradigm to bridge the scale between population dynamics and the microscopic complexity of the individual cells physiology.NEW & NOTEWORTHY Population models are a powerful mathematical tool to study the dynamics of neuronal networks and to simulate the brain at macroscopic scales. We present a mean-field model capable of quantitatively predicting the temporal dynamics of a network of complex spiking neuronal models, from Integrate-and-Fire to Hodgkin-Huxley, thus linking population models to neurons electrophysiology. This opens a perspective on generating biologically realistic mean-field models from electrophysiological recordings.

Abstract
Background Oriented Schlieren (BOS) is an optical technique sensitive to the first spatial derivative of the refractive index inside a light-transmitting medium. Compared to other Schlieren-like techniques, BOS is more versatile and allows to capture bi-dimensional gradients rather than just one spatial component. We propose to adopt BOS for studying the capabilities of surface dielectric barrier discharges to work like plasma actuators in flow control applications. The characteristics of the BOS we implemented at this purpose are discussed, together with few results concerning the ionic wind produced by the discharge in absence of an external airflow.

Abstract
AIM This study describes five experimental techniques for the surgical treatment of giant aneurysms based on the resection of the aneurysm sac and reconstruction of the arterial wall. METHODS The aneurysm was realized with a venous graft implanted with end-to-side anastomosis on the common carotid artery on 50 rabbits (with each technique realized in 10 rabbits). The first two experimental techniques (A and B) involve the reconstruction of the artery wall by a synthetic dural patch and by direct suture reinforced by a venous patch, respectively. In the model C a collateral branch arising from the aneurysm is resected and reimplanted on the parent artery after aneurysm resection. In the experimental model D the arterial defect is closed by a venous patch surrounding the whole arterial wall and sutured with the aid of fibrin glue. In the model E clamping of the parent artery proximal to the aneurysm site and termino-lateral anastomosis with the contralateral artery lead to the thrombosis of the aneurysm fulled only by refluent flow. RESULTS AND CONCLUSION The venous pouch experimental models are useful to realize giant aneurysms. The above described techniques allow to realize the reconstruction of the arterial wall without stenosis and shortening the clamping time.

Abstract
Women are less susceptible to the cerebrovascular complications of hypertension, such as a stroke and vascular dementia. The mechanism of such protection may be related to a reduced vulnerability of women to the cerebrovascular actions of hypertension. To test this hypothesis, we used a model of hypertension based on infusion of angiotensin II (ANG II), an octapeptide that plays a key role in hypertension and produces cerebrovascular dysregulation. Cerebral blood flow (CBF) was monitored by laser-Doppler flowmetry in anesthetized (urethane-chloralose) C57BL/6J male and female mice equipped with a cranial window. ANG II administration (0.25 mug.kg(-1).min(-1) iv x 30-45 min) elevated arterial pressure equally in both sexes but attenuated the CBF increase induced by whisker stimulation or by the endothelium-dependent vasodilator acetylcholine (ACh) in male but not in female mice. The administration of ANG II for 7 days (2.74 mg.kg(-1).day(-1)), using osmotic minipumps, also attenuated these cerebrovascular responses in male, but not female, mice. The reduced susceptibility to the effect of ANG II in female mice was abolished by ovariectomy and reinstated by estrogen administration to ovariectomized mice. Administration of estrogen to male mice abolished the ANG II-induced attenuation of CBF responses. We conclude that female mice are less susceptible to the cerebrovascular dysregulation induced by ANG II, an effect related to estrogen. Such protection from the deleterious cerebrovascular effects of hypertension may play a role in the reduced vulnerability to the cerebrovascular complications of hypertension observed in women.

Abstract
Reactive oxygen species (ROS) play a central role in neuronal pathophysiology and in neurodegenerative disorders. However, recent evidence indicates that these molecules also operate as signaling intermediates in a variety of physiological settings, including cell protection from apoptosis. Data presented here strongly support such a dual role for oxidants in neuronal cell homeostasis. In rat pheocromocytoma cells, cell rescue by the nerve growth factor (NGF) is accompanied by a transient burst of ROS generated in the cytosol by a GTPase-dependent mechanism. Within the NGF signaling cascade, ROS lie upstream and are necessary for activation/phosphorylation of AKT/PKB and of the antiapoptotic transcription factor cAMP-responsive element-binding protein (CREB). Conversely, an increase in mitochondrial oxygen species heralds apoptosis of serum-deprived cells, and these events can be prevented by cell exposure to NGF or by treatment with the mitochondrially targeted antioxidant MitoQ. Importantly, NGF-mediated decrease of mitochondrial ROS is dependent on the transcriptional up-regulation of the manganese superoxide dismutase (MnSOD) by active CREB. These observations therefore outline a circuitry whereby cytosolic redox signaling promotes neuronal cell survival by increasing the mitochondrial antioxidant defenses.

Abstract
In order to investigate the appearance of a rest-activity periodicity, spontaneous motor behavior of five low-risk preterm infants (gestational age range 27-31 weeks) was monitored for 24 hours at weekly intervals until term. Using a time lapse videorecorder (6.5 fields/sec.) both slow and rapid movements were counted every three minutes; this interval was adopted as basic chronological paradigm in order to evaluate the daily distribution of motor activity. The results of quantitative analysis showed a developmental trend of motor behavior which increased from earliest conceptional ages (C.A.) until 32-33 weeks, and decreased around 36-37 weeks C.A. Prolonged complete rest intervals are rare at low C.A., while in older infants (approx. 40 weeks C.A.) an initial tendency to organize motor activity in ultradian cycle-like periods seems to be more evident, contemporary with consolidated behavioral states.
