- Abstract
The translation inhibitor and tumor suppressor Pdcd4 was reported to be lost in various tumors and put forward as prognostic marker in tumorigenesis. Decreased Pdcd4 protein stability due to PI3K-mTOR-p70S6K1 dependent phosphorylation of Pdcd4 followed by v-TrCP1-mediated ubiquitination, and proteasomal destruction of the protein was characterized as a major mechanism contributing to the loss of Pdcd4 expression in tumors. In an attempt to identify stabilizers of Pdcd4, we used a luciferase-based high-throughput compatible cellular assay to monitor phosphorylation-dependent proteasomal degradation of Pdcd4 in response to mitogen stimulation. Following a screen of approximately 2000 compounds, we identified 1,2-bis(4-chlorophenyl)disulfide as a novel Pdcd4 stabilizer. To determine an initial structure-activity relationship, we used 3 additional compounds, synthesized according to previous reports, and 2 commercially available compounds for further testing, in which either the linker between the aryls was modified (compounds 2-4) or the chlorine residues were replaced by groups with different electronic properties (compounds 5 and 6). We observed that those compounds with alterations in the sulfide linker completely lost the Pdcd4 stabilizing potential. In contrast, modifications in the chlorine residues showed only minor effects on the Pdcd4 stabilizing activity. A reporter with a mutated phospho-degron verified the specificity of the compounds for stabilizing the Pdcd4 reporter. Interestingly, the active diaryl disulfides inhibited proliferation and viability at concentrations where they stabilized Pdcd4, suggesting that Pdcd4 stabilization might contribute to the anti-proliferative properties. Finally, computational modelling indicated that the flexibility of the disulfide linker might be necessary to exert the biological functions of the compounds, as the inactive compound appeared to be energetically more restricted.

We have designed and synthesized a series of new imidazole-based compounds structurally related to an antiprotozoal agent with nanomolar activity which we identified recently. The new analogues possess micromolar activities against Trypanosoma brucei rhodesiense and Leishmania donovani and nanomolar potency against Plasmodium falciparum. Most of the analogues displayed IC 50 within the low nanomolar range against Trypanosoma cruzi, with very high selectivity toward the parasite. Discussion of structure-activity relationships and in vitro biological data for the new compounds are provided against a number of different protozoa. The mechanism of action for the most potent derivatives (5i, 6a-c, and 8b) was assessed by a target-based assay using recombinant T. cruzi CYP51. Bioavailability and efficacy of selected hits were assessed in a T. cruzi mouse model, where 6a and 6b reduced parasitemia in animals >99% following intraperitoneal administration of 25 mg/kg/day dose for 4 consecutive days.

Background: Cervical spondylotic myelopathy (CSM) is a degenerative disease that represents the most common spinal cord disorder in adults. The best treatment option has remained controversial. We performed a prospective study to evaluate the clinical, radiographic, and neurophysiologic outcomes for anterior cervical corpectomy in the treatment of CSM. Methods: From January 2011 to January 2017, 60 patients with CSM were prospectively enrolled in the present study. The patients were divided according to the modified Japanese Orthopaedic Association scale (mJOA) score into 2 groups: group A, patients with mild to moderate CSM (mJOA score ≥13); and group B, patients with severe myelopathy (mJOA score

Bifunctional quinolinonyl DKA derivatives were first described as nonselective inhibitors of 3′-processing (3′-P) and strand transfer (ST) functions of HIV-1 integrase (IN), while 7-aminosubstituted quinolinonyl derivatives were proven IN strand transfer inhibitors (INSTIs) that also displayed activity against ribonuclease H (RNase H). In this study, we describe the design, synthesis, and biological evaluation of new quinolinonyl diketo acid (DKA) derivatives characterized by variously substituted alkylating groups on the nitrogen atom of the quinolinone ring. Removal of the second DKA branch of bifunctional DKAs, and the amino group in position 7 of quinolinone ring combined with a fine-tuning of the substituents on the benzyl group in position 1 of the quinolinone, increased selectivity for IN ST activity. In vitro, the most potent compound was 11j (IC50 = 10 nM), while the most active compounds against HIV infected cells were ester derivatives 10j and 10l. In general, the activity against RNase H was negligible, with only a few compounds active at concentrations higher than 10 μM. The binding mode of the most potent IN inhibitor 11j within the IN catalytic core domain (CCD) is described as well as its binding mode within the RNase H catalytic site to rationalize its selectivity.

A series of antiviral basic quinolinonyl diketo acid derivatives were developed as inhibitors of HIV-1 IN. Compounds 12d,f,i inhibited HIV-1 IN with IC50 values below 100 nM for strand transfer and showed a 2 order of magnitude selectivity over 3′-processing. These strand transfer selective inhibitors also inhibited HIV-1 RNase H with low micromolar potencies. Molecular modeling studies based on both the HIV-1 IN and RNase H catalytic core domains provided new structural insights for the future development of these compounds as dual HIV-1 IN and RNase H inhibitors. © 2014 American Chemical Society.

HIV-1 reverse transcriptase (RT)-associated RNase H activity is an essential function in viral genome retrotranscription. RNase H is a promising drug target for which no inhibitor is available for therapy. Diketo acid (DKA) derivatives are active site Mg 2+ -binding inhibitors of both HIV-1 RNase H and integrase (IN) activities. To investigate the DKA binding site of RNase H and the mechanism of action, six couples of ester and acid DKAs, derived from 6-[1-(4-fluorophenyl)methyl-1 H -pyrrol-2-yl)]-2,4-dioxo-5-hexenoic acid ethyl ester (RDS1643), were synthesized and tested on both RNase H and IN functions. Most of the ester derivatives showed selectivity for HIV-1 RNase H versus IN, while acids inhibited both functions. Molecular modeling and site-directed mutagenesis studies on the RNase H domain demonstrated different binding poses for ester and acid DKAs and proved that DKAs interact with residues (R448, N474, Q475, Y501, and R557) involved not in the catalytic motif but in highly conserved portions of the RNase H primer grip motif. The ester derivative RDS1759 selectively inhibited RNase H activity and viral replication in the low micromolar range, making contacts with residues Q475, N474, and Y501. Quantitative PCR studies and fluorescence-activated cell sorting (FACS) analyses showed that RDS1759 selectively inhibited reverse transcription in cell-based assays. Overall, we provide the first demonstration that RNase H inhibition by DKAs is due not only to their chelating properties but also to specific interactions with highly conserved amino acid residues in the RNase H domain, leading to effective targeting of HIV retrotranscription in cells and hence offering important insights for the rational design of RNase H inhibitors.

The D-amino acid, D-aspartate, is abundant in the developing brain, yet its function is unknown. Addition of d-aspartate to hippocampal or cortical slices prepared from 8- to 9-day-old rats stimulated polyphosphoinositide (PI) hydrolysis to a slightly greater extent than L-glutamate. The action of D-aspartate was concentration-dependent with an apparent EC(50) value of 1 mM and a maximal stimulation of 6- and 20-fold in cortical and hippocampal slices, respectively. Stimulation of PI hydrolysis by D-aspartate was largely reduced by pharmacological blockade of mGlu5 metabotropic glutamate receptors with 2-methyl-6-(phenylethynyl)pyridine. These findings suggest that D-aspartate behaves as an endogenous agonist of mGlu5 receptors during early postnatal life.

- Abstract
Background: Enhanced recovery after surgery (ERAS) is a multidisciplinary approach aimed at reducing the length of hospital stay, improving patient outcomes, and reducing the overall cost of care. Although ERAS protocols have been widely adopted in various surgical fields, their application in cranial surgery remains relatively limited., Methods: Considering that the aging of the population presents significant challenges to healthcare systems, and there is currently no ERAS protocol available for geriatric patients over the age of 65 requiring cranial surgery, this article proposes a new ERAS protocol for this population by analyzing successful ERAS protocols and optimal perioperative care for geriatric patients described in the literature., Results: Our aim is to develop a feasible, safe, and effective protocol for geriatric patients undergoing elective craniotomy, which includes preoperative, intraoperative, and postoperative assessments and management, as well as outcome measures., Conclusions: This multidisciplinary and evidence-based ERAS protocol has the potential to reduce perioperative morbidity, improve functional recovery, and enhance postoperative outcomes after cranial surgery in elderly. Further research will be necessary to establish strict guidelines., (Copyright © 2024 Elsevier Inc. All rights reserved.)

- Abstract
Objectives: To evaluate the applicability of Bosniak 2019 criteria on a monophasic portal venous phase using rapid kilovoltage-switching DECT (rsDECT)., Materials and Methods: One hundred twenty-seven renal masses assessed on rsDECT were included, classified according to Bosniak 2019 classification using MRI as the reference standard. Using the portal venous phase, virtual monochromatic images at 40, 50, and 77 keV; virtual unenhanced (VUE) images; and iodine map images were reconstructed. Changes in attenuation values between VUE and 40 keV, 50 keV, and 77 keV measurements were computed and respectively defined as ∆HU
40keV , ∆HU50keV , and ∆HU77keV . The values of ∆HU40keV , ∆HU50keV , and ∆HU77keV thresholds providing the optimal diagnostic performance for the detection of internal enhancement were determined using Youden index., Results: Population study included 25 solid renal masses (25/127, 20%) and 102 cystic renal masses (102/127, 80%). To differentiate solid to cystic masses, the specificity of the predefined 20 HU threshold reached 88% (95%CI: 82, 93) using ∆HU77keV and 21% (95%CI: 15, 28) using ∆HU40keV . The estimated optimal threshold of attenuation change was 19 HU on ∆HU77keV , 69 HU on ∆HU50eV , and 111 HU on ∆HU40eV . The rsDECT classification was highly similar to that of MRI for solid renal masses (23/25, 92%) and for Bosniak 1 masses (62/66, 94%). However, 2 hyperattenuating Bosniak 2 renal masses (2/26, 8%) were classified as solid renal masses on rsDECT., Conclusion: DECT is a promising tool for Bosniak classification particularly to differentiate solid from Bosniak I-II cyst. However, known enhancement thresholds must be adapted especially to the energy level of virtual monochromatic reconstructions., Clinical Statement: DECT is a promising tool for Bosniak classification; however, known enhancement thresholds must be adapted according to the types of reconstructions used and especially to the energy level of virtual monochromatic reconstructions., Key Points: • To differentiate solid to cystic renal masses, predefined 20 HU threshold had a poor specificity using 40 keV virtual monochromatic images. • Most of Bosniak 1 masses according to MRI were also classified as Bosniak 1 on rapid kV-switching dual-energy CT (rsDECT). • Bosniak 2 hyperattenuating renal cysts mimicked solid lesion on rsDECT., (© 2023.

- Abstract
Pre-op spinal arterial mapping is crucial for complex aortic repair. This study explores the utility of non-selective cone beam computed tomography (CBCT) for pre-operative spinal arterial mapping to identify the Adamkiewicz artery (AKA) in patients undergoing open or endovascular repair of the descending thoracic or thoracoabdominal aorta at risk of spinal cord ischemia. Pre-operative non-selective dual-phase CBCT after intra-aortic contrast injection was performed in the aortic segment to be treated. The origin of detected AKA was assessed based on image fusion between CBCT and pre-interventional computed tomography angiography. Then, the CBCT findings were compared with the incidence of postoperative spinal cord ischemia (SCI). Among 21 included patients (median age: 68 years, 20 men), AKA was detected in 67% within the explored field of view, predominantly from T7 to L1 intercostal and lumbar arteries. SCI occurred in 14%, but none when AKA was not detected ( p < 0.01). Non-selective CBCT for AKA mapping is deemed safe and feasible, with potential predictive value for post-surgical spinal cord ischemia risk. The study concludes that non-selective aortic CBCT is a safe and feasible method for spinal arterial mapping, providing promising insights into predicting post-surgical SCI risk.

- Abstract
A systematic and narrative literature review was performed, focusing attention on the anatomy of the area located at the junction of the sphenoid and the basal portion of the temporal bone (petrous bone, petrous apex, upper petro-clival region) encircled by the free edge of the tentorium, the insertion of the tentorium itself to the petrous apex and the anterior and posterior clinoid processes that give rise to three distinct dural folds or ligaments: the anterior petroclinoid ligament, the posterior petroclinoid ligament and the interclinoid ligament. These dural folds constitute the posterior portion of the roof of the cavernous sinus denominated "the oculomotor triangle". The main purpose of this review study was to describe this anatomical region, particularly in the light of the relationships between the anterior margin of the free edge of the tentorium and the above-mentioned components of the sphenoid and petrous bone.

- Abstract
Background: Spontaneous and nontraumatic epidural hematoma (SEDH) is a rare entity. Etiology is various, including vascular malformations of the dura mater, hemorrhagic tumors, and coagulation defects. The association between SEDH and craniofacial infections is rather unusual., Methods: We performed a systematic review of the available literature using the PubMed, Cochrane Library, and Scopus research databases. Literature research was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We exclusively included studies reporting demographic and clinical data, published until October 31, 2022. We also report one case from our experience., Results: A total of 18 scientific publications, corresponding to 19 patients, met the inclusion criteria for the qualitative and quantitative analysis. Patients were mostly adolescents, with a clear male predominance. SEDHs frequently occurred in the frontal area, usually near the site of the infection. Surgical evacuation was the treatment of choice with good postoperative outcomes. Endoscopy of the involved paranasal sinus should be achieved as soon as possible to remove the cause of the SEDH., Conclusion: SEDH may occur as a rare and life-threatening complication of craniofacial infections; therefore, prompt recognition and treatment are mandatory., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Surgical Neurology International.)

- Abstract
Objective: Although the supraorbital (SO) keyhole approach has a wide range of indications, its routine usefulness with the advance of current technology has not been fully evaluated. In an attempt to address this issue, a cadaveric morphometric analysis to the supra- and parasellar regions was performed, comparing the standard Pterional craniotomy (PT) with the SO keyhole., Methods: ETOH-fixed and silicone-injected human cadaveric heads were used. SO (n = 8) and PT craniotomies (n = 8) were performed. Pre- and post-dissection CT, along with pre-dissection MRI scans were also completed for neuro-navigation purposes, aimed to verify predetermined anatomical landmarks selected for morphometric analysis., Results: Notwithstanding the smaller craniotomy, the SO approach allowed optimal anatomical exposure when compared to the PT approach. With 30° of head rotation, the SO keyhole showed a wider surgical field of the suprasellar region., Conclusions: Using detailed preoperative image-guided surgical planning, the SO keyhole approach offered an appropriate alternative route to the supra- and parasellar regions, compared to the PT craniotomy., (© 2023.

- Abstract
The aim of this anatomical study is to describe the anatomy of the hypoglossal nerve (HN) from its origin to the extracranial portion as it appears by performing a combined posterolateral and anterolateral approach to the craniovertebral junction (CVJ). Twelve fresh, non-formalin-fixed adult cadaveric heads (24 sides) were analyzed for the simulation of the combined lateral approach to the CVJ. The HN is divided into three main parts: cisternal, intracanalicular, and extracranial The anatomical relationships between the HN and other nerves, muscles, arteries and veins were carefully recorded, and some measurements were made between the HN and related structures. Thus, various landmarks were determined for the easy identification of the HN. Understanding the detailed anatomy of the HN and its relationships with the surrounding structures is crucial to prevent some complications during CVJ surgery., Competing Interests: None declared., (Thieme.

- Abstract
Surgical removal of tumors of the atrium is challenging due to their deep location, vascularization, and to their complex three-dimensional relationships with the highly functional white matter fibers of the region. To assess the feasibility and the effectiveness of the ipsilateral interhemispheric transprecuneus approach (IITA) for tumors involving the atrium and the posterior third of the temporal horn, a retrospective chart review of all patients who had undergone a surgical treatment for intraventricular tumors between January 2008 and January 2017 was performed, and the step-by-step approach is described. Ten patients affected by lesions of the atrium of the lateral ventricle underwent surgical treatment, seven of which were approached through the IITA. The mean age was 42.8 years (range 6-63 years). The symptoms presented included severe, drug-resistant headache (90%), lateral homonymous hemianopsia (50%), seizures (30%), and speech disturbances (30%). Histological examinations revealed seven patients with meningioma (70%), one with a metastasis (10%), one with a choroid plexus papilloma (10%) and one with a cavernoma (10%). In all cases, a gross total removal was obtained. All patients had a significant improvement in their headache. Two patients experienced a worsening of the pre-operative visual disturbances, while two patients had a significant improvement. No patients without pre-operative visual disturbances described a post-operative worsening of visual symptoms. The IITA represents a feasible approach for tumors of the atrium. The three-quarter prone position facilitates the enlargement of the interhemispheric fissure by increasing the working angle and facilitating the exposure of the lateral wall of the atrium.

- Abstract
Background: Complex intracranial aneurysms (CIAs) are challenging pathologies to treat. Characteristics making an aneurysm complex include dimension, history of previous treatment, location, absence of collateral circulation, intraluminal thrombosis, and calcification of the wall. The goal of the therapeutic process is to exclude the malformation from the cerebral circulation and both endovascular and surgical treatments are valid procedures., Methods: Between 1990 and 2020, 170 CIAs were treated at our institution (33 ruptured, 137 unruptured). They were 3 prepetrous segment of the internal carotid artery (ICA), 14 purely intracavernous sinus, 27 intracavernous with subarachnoid extension, 60 paraclinoid, 4 ICA bifurcation, 15 anterior communicating artery, 24 middle cerebral artery, and 23 in the posterior circulation. All the patients underwent neuroradiologic examinations and images were evaluated by the neurosurgical and interventional radiologist team. Endovascular treatment was considered as the treatment of choice. Alternative treatment was surgical clipping; revascularization procedures were performed when neither endovascular treatment nor direct clipping were possible., Results: Of 170 patients, 45 underwent endovascular treatment, 77 surgical clipping, and 55 revascularization procedures. In the unruptured group, 12 patients died, 22 reported major complications, 3 had minor complications, and 101 had an uneventful postoperative course. In the ruptured group, 9 patients died, 10 had minor complications, 1 minor complication, and 13 had a complete recovery., Conclusions: Endovascular treatment should represent the treatment of choice for CIAs. Alternative treatments include direct surgical clipping and revascularization. Overall, the correct identification of the therapeutic process guarantees a good clinical outcome., (Copyright © 2021.

- Abstract
Surgical treatment of intraventricular lesions is challenging because of their deep location, vascularization, and their complex relationships with white matter fibers. The authors undertook this study to describe the microsurgical anatomy of the white matter fibers covering the lateral wall of the atrium and temporal horn and to demonstrate how the ipsilateral interhemispheric transprecuneal approach can be safely used to remove lesions of this region sparing the anatomo-functional integrity of the fibers themselves. A detailed description of the approach including operative measurements is also given. The Klingler' technique with progressive identification of white matter fibers covering the lateral wall of the atrium and temporal horn was performed on ten formalin-fixed human hemispheres. Then, ten fresh, non-formalin-fixed non-silicon-injected adult cadaveric heads were analyzed for the simulation of the ipsilateral interhemispheric transprecuneal approach. Three illustrative cases are presented. The simulation of the interhemispheric transprecuneal approach on ten fresh non-formalin-fixed specimens showed that a 10 to 20 mm corticotomy perpendicular to the parieto-occipital sulcus at the junction with the cingulum allows a wide corridor for the exposure of the entire atrial cavity and the posterior third of the temporal horn. The ipsilateral interhemispheric transprecuneus approach represents a safe and effective option for tumors involving the atrium and the posterior third of the temporal horn.

- Abstract
Background: Cervical spondylotic myelopathy (CSM) is a degenerative disease that represents the most common spinal cord disorder in adults. The best treatment option has remained controversial. We performed a prospective study to evaluate the clinical, radiographic, and neurophysiologic outcomes for anterior cervical corpectomy in the treatment of CSM., Methods: From January 2011 to January 2017, 60 patients with CSM were prospectively enrolled in the present study. The patients were divided according to the modified Japanese Orthopaedic Association scale (mJOA) score into 2 groups: group A, patients with mild to moderate CSM (mJOA score ≥13); and group B, patients with severe myelopathy (mJOA score <13). Data were collected for each participating subject, including demographic information, symptoms, medical history, radiologic and neurophysiologic features, and functional impairment., Results: Of the 60 patients, 35 were men (58.3%) and 25 were women (41.7%). Their average age was 57.48 ± 10.60 years. The mean symptom duration was 25.33 ± 16.00 months; range, 3-57 months). Of the 60 patients, 22 had undergone single-level corpectomy and 36 multilevel corpectomy. A significant improvement in the motor evoked potentials was observed in both groups., Conclusions: Single- and multilevel corpectomy are valid and safe options in the treatment of CSM. In the present prospective study, a statistically significant improvement in the mJOA score and neurophysiologic parameters was observed for both moderate and severe forms of CSM., (Copyright © 2020 Elsevier Inc.

- Abstract
Although most cases of acute nonvariceal gastrointestinal bleeding (GIB) either spontaneously resolve or respond to medical management and endoscopic therapy, there are still a significant proportion of severe patients who require emergency angiography and endovascular treatment. Over the past three decades, transcatheter arterial embolization (TAE) has become the first-line therapy for the management of acute nonvariceal GIB that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer liquid embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the treatment of bleeding for a variety of indications. TAE is a safe and effective minimally invasive alternative to surgery, when endoscopic treatment fails to control acute bleeding from the gastrointestinal tract. In this article we review the current role of angiography and TAE in the management of acute nonvariceal GIB., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

- Abstract
Background: The fornix is a region of greatest neurosurgical interest in regards to its complex anatomy and surgical approaches to this area. The objective of this study was to evaluate the morphology of the triangular recess (TR) and its role in the growth pattern of the colloid cysts (CC) within the third ventricle and in the choice of the surgical approach for their removal. Furthermore, to compare the results of the dissections with measurements performed on a magnetic resonance imaging scan., Methods: In the anatomic study, 20 cadaveric specimens were dissected and analyzed. In the radiologic study, a magnetic resonance imaging scan was performed in 20 healthy volunteers. In the clinical study, a retrospective analysis of all the patients affected with CCs microsurgically removed at our institute between 2010 and 2018 was conducted., Results: In the anatomic study, the width, height, and the area of the TR were respectively 0.31 cm, 0.33cm, and 0.051 cm
2 . In the radiologic study, 3 different typologies of TR were identified: open recess in ventriculomegaly (7 patients); open recess in physiologic ventricular system (3 patients); closed or blind recess (10 patients). Three different growth patterns of CCs were identified: type 1) CCs localized at the foramen of Monro growing behind the fornix and below the third ventricular roof; type 2) CCs growing rostrally between the column of fornix; and type 3) CCs growing above the plane of the third ventricular roof., Conclusions: The anatomy of the TR influences the growth pattern of CC within the ventricular cavity and determines the surgical strategy for their removal., (Copyright © 2019 Elsevier Inc.

- Abstract
Background: Partial splenic embolization (PSE) has been used to improve thrombocytopenia related to hypersplenism. The optimal embolic agent is still debated. The purpose of this study was to evaluate the safety, hematologic response and outcomes of PSE with cyanoacrylate glue for oncological patients with hypersplenism-related thrombocytopenia requiring systemic chemotherapy (SC)., Methods: Retrospective single-center observational report of cancer patients with thrombocytopenia related to hypersplenism and requiring SC who underwent PSE with N-butyl cyanoacrylate-methacryloxy sulfolane (NBCA-MS) Glubran
® 2 glue between February 2015 and September 2017. All patients were treated under local anesthesia with a Glubran® 2/Lipiodol® mixture of 1:5 ratio. They all received empiric antibiotic coverage. Splenic volume and parenchyma infarction rate were evaluated by CT scan within 1 month of PSE. Primary and secondary endpoints of the current study included a platelet count increase >150×109 /L and the initiation of SC, respectively. Periprocedural laboratory values and adverse events were recorded., Results: PSE was performed in eight patients (6 males, 2 females; median age, 59 years; range, 33-75 years) for a technical success of 100%. For procedures with adequate follow-up, primary and secondary endpoints were achieved in 100% (7 of 7 patients) and 100% (7 of 7 patients) of patients, respectively. One patient died before follow-up, unrelated to the procedure. Mean splenic infarction post-PSE was 55% (range, 21-70%) on CT scan. For 7 patients with laboratory follow-up, the mean platelet count significantly increased from 74×109 /L [range, (62-83) ×109 /L] immediately before PSE to a peak level of 272×109 /L [range, (161-417) ×109 /L] 10 days after PSE (P<0.05). All patients could receive SC after PSE. No non-target glue embolization occurred. All patients experienced a transient and moderate postembolization syndrome. No severe postembolization syndrome occurred. No major complication was reported. The mean overall survival was 7.9 months (range, 0.6-10.4 months) among the 8 patients after PSE., Conclusions: PSE with cyanoacrylate glue is safe and effective in the management of thrombocytopenia related to hypersplenism in cancer patients. It allows sufficient platelet count improvement for administration of SC., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.- Published

- Abstract
We have designed and synthesized a series of new imidazole-based compounds structurally related to an antiprotozoal agent with nanomolar activity which we identified recently. The new analogues possess micromolar activities against Trypanosoma brucei rhodesiense and Leishmania donovani and nanomolar potency against Plasmodium falciparum. Most of the analogues displayed IC
50 within the low nanomolar range against Trypanosoma cruzi, with very high selectivity toward the parasite. Discussion of structure-activity relationships and in vitro biological data for the new compounds are provided against a number of different protozoa. The mechanism of action for the most potent derivatives (5i, 6a-c, and 8b) was assessed by a target-based assay using recombinant T. cruzi CYP51. Bioavailability and efficacy of selected hits were assessed in a T. cruzi mouse model, where 6a and 6b reduced parasitemia in animals >99% following intraperitoneal administration of 25 mg/kg/day dose for 4 consecutive days.- Published

- Abstract
The final stages of polio eradication are proving more difficult than the early phases, and the development of effective drugs and treatments is considered a priority; thus, the research is ongoing. A screening of our in-house chemical library against poliovirus Sabin strains led to the identification of compounds 5 and 6 as hits active at submicromolar concentrations. Derivatives of these compounds were synthesized as a preliminary structure-activity-relationship study. Among them, 7 and 11 were highly active against poliovirus Sabin 1-3. Compound 11 was also very potent against a large panel of wild and vaccine-derived polioviruses. Time-of-addition experiments suggest that 5 and 7 could be active at an early stage of viral replication, whereas 11 was active at same concentration at all stages of viral replication. A ligand-based approach was applied to find the common structural features shared by the new compounds and already-known poliovirus inhibitors.

- Abstract
Heparanase is the only mammalian endo-β-d-glucuronidase involved in a variety of major diseases. The up-regulation of heparanase expression increases tumor size, angiogenesis, and metastasis, representing a validated target in the anti-cancer field. To date, only a few small-molecule inhibitors have been described, but none have gotten through pre-clinical development. Previously, we explored 2-(4-(4-(bromo-methoxybenzamido)benzylamino)phenyl) benzazole derivatives as anti-heparanase agents, proposing this scaffold for development of broadly effective heparanase inhibitors. Herein, we report an extended investigation of new symmetrical 2-aminophenyl-benzazolyl-5-acetate derivatives, proving that symmetrical compounds are more effective than asymmetrical analogues, with the most-potent compound, 7g, being active at nanomolar concentration against heparanase. Molecular docking studies were performed on the best-acting compounds 5c and 7g to rationalize their interaction with the enzyme. Moreover, invasion assay confirmed the anti-metastatic potential of compounds 5c, 7a, and 7g, proving the inhibition of the expression of proangiogenic factors in tumor cells.

- Abstract
Drug-eluting bead transarterial chemoembolization (DEB-TACE) is a relative new endovascular treatment based on the use of microspheres to release chemotherapeutic agents within a target lesion with controlled pharmacokinetics. This aspect justifies the immediate success of DEB-TACE, that nowadays represents one of the most used treatments for unresectable hepatocellular carcinoma. However, there is no consensus about the choice of the best embolotherapy technique. In this review, we describe the available microspheres and report the results of the main comparative studies, to clarify the role of DEB-TACE in the hepatocellular carcinoma management. We underline that there is no evidence about the superiority of DEB-TACE over conventional TACE in terms of efficacy, but there may be some benefits with respect to safety especially with the improvement of new technologies.

- Abstract
Background: The Meckel's cave (MC) is commonly affected by neoplastic lesions that often require neurosurgical treatment. We simulated the posterior petrous apicectomy (PPA) on fresh cadavers to verify the in vivo feasibility of the approach. We proposed a new classification system of MC meningioma based on the extent of middle cranial fossa (MCF) involvement., Methods: Ten fresh, non-formalin-fixed specimens were used in this study. Through a retrosigmoid approach, 20 PPAs were performed. Subsequently, the cerebral hemispheres were removed to quantify the MCF exposure and dimensions of the suprameatal tubercle. Twenty-four patients operated on for MC meningioma were classified as follows: group 1, tumor <3 cm; group 2, tumor >3 cm. Group 2 was subdivided into to 5 subtypes: 2A, tumor of the MCF; 2B, tumor of the posterior cranial fossa; 2C, tumor of MCF and posterior cranial fossa; 2C type I, MCF <15 mm; and 2C type II, MCF >15 mm., Results: The extent of MCF exposure through the PPA is 13 mm. Mean suprameatal tubercle dimensions were 10.4 mm × 3.8 mm. Mean extent of bony removal for the PPA was 10.2 mm. PPA was successfully performed in 3 patients without major neurologic sequelae., Conclusions: Preliminary results obtained with the PPA in 2C type I meningiomas are encouraging. The new classification system proposed can be useful in clinical practice, especially in the choice of the most suitable surgical approach for dumbbell meningiomas., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: Femoral pseudoaneurysm (PA) is a frequent complication of arterial access for endovascular procedures. Surgery has traditionally been considered as the gold standard of therapy. We aimed to report our experience of percutaneous ultrasound (US)-guided balloon-assisted embolization with cyanoacrylate glue for the treatment of iatrogenic femoral PAs., Methods: Retrospective two-center study of patients with femoral iatrogenic PAs treated by N-butyl cyanoacrylate-methacryloxy sulfolane (NBCA-MS) Glubran
® 2 glue embolization between July 2013 and November 2017. All patients underwent contralateral arterial access with balloon placement of an appropriate size in front of the PA neck before glue/lipiodol embolization in a 1:1 ratio by percutaneous US-guided puncture of the aneurysmal sac under fluoroscopy control., Results: Twenty-three patients (12 females, 11 males; median age, 79 years; range, 18-93 years) were included. Median PA size was 34 mm (range, 17-60 mm). The median time to treatment was 5 days (range, 1-30 days). Twenty patients (86.9%) were successfully treated by glue injection alone. The three remaining patients (13.1%) with persistent PA or associated arterial-venous fistula were immediately treated during the same procedure by additional stent-graft. Then, overall immediate and 1-month clinical success rates were 100%. No surgical conversion was necessary. No recurrence was reported during the median follow-up of 11 months (range, 2-73 months). Two (8.7%) puncture-related complications occurred at the contralateral arterial access site, which spontaneously resolved. No non-target glue embolization occurred., Conclusions: US-guided balloon-assisted glue embolization is safe and effective to treat iatrogenic femoral PAs in most cases, offering complete exclusion of the PA and avoiding the morbidity of open surgery., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.- Published

- Abstract
Heparanase is the sole mammalian enzyme capable of cleaving glycosaminoglycan heparan sulfate side chains of heparan sulfate proteoglycans. Its altered activity is intimately associated with tumor growth, angiogenesis, and metastasis. Thus, its implication in cancer progression makes it an attractive target in anticancer therapy. Herein, we describe the design, synthesis, and biological evaluation of new benzazoles as heparanase inhibitors. Most of the designed derivatives were active at micromolar or submicromolar concentration, and the most promising compounds are fluorinated and/or amino acids derivatives 13a, 14d, and 15 that showed IC
50 0.16-0.82 μM. Molecular docking studies were performed to rationalize their interaction with the enzyme catalytic site. Importantly, invasion assay confirmed the antimetastatic potential of compounds 14d and 15. Consistently with its ability to inhibit heparanase, compound 15 proved to decrease expression of genes encoding for proangiogenic factors such as MMP-9, VEGF, and FGFs in tumor cells.- Published

- Abstract
We discovered a series of azole antifungal compounds as effective antiprotozoal agents. They displayed promising inhibitory activities within the micromolar-submicromolar range against P. falciparum, L. donovani, and T. b. rhodesiense. Moreover, most of such compounds showed excellent nanomolar IC
50 against T. cruzi, showing also very low cytotoxicity. Discussion of structure-activity relationships and biological data for these compounds are provided against the different parasites. To assess the mechanism of action against T. cruzi we proved that the most potent compounds (3b, 3j-l) inhibited the T. cruzi CYP51. Moreover, the most active derivative 3j dramatically reduced parasitemia in T. cruzi mouse model without acute toxicity., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)- Published
