The lateralized cerebellum: insights into motor, cognitive, and affective functioning across ages: a scoping review.

Research on the cerebellum and its functional organization has significantly expanded over the last decades, expanding our comprehension of its role far beyond motor control, including critical contributions to cognition and affective processing. Notably, the cerebellar lateralization mirrors contralateral brain lateralization, a complex phenomenon that remains unexplored, especially across different stages of life. The present work aims to bridge this gap by providing a comprehensive scoping review of the lateralization of motor, cognitive, and affective functioning within the cerebellum across the lifespan.

Non-Innocent Role of Sacrificial Anodes in Electrochemical Nickel-Catalyzed C(sp)-C(sp) Cross-Electrophile Coupling.

Sacrificial anodes composed of inexpensive metals such as Zn, Fe, and Mg are widely used to support electrochemical nickel-catalyzed cross-electrophile coupling (XEC) reactions, in addition to other reductive electrochemical transformations. Such anodes are appealing because they provide a stable counter-electrode potential and typically avoid interference with the reductive chemistry. The present study outlines the development of an electrochemical Ni-catalyzed XEC reaction that streamlines access to a key pharmaceutical intermediate.

Why do a lung biopsy for benign lesions?

Background: Transthoracic needle biopsy of lung lesions is a well-established procedure for the diagnosis of lung lesions. The literature focuses on the diagnosis of malignant lesions with an often reported accuracy rate of more than 90%. Experience showed that biopsy can identify sometimes incidentally, also benign lesions.

Effects of seasonality in emergency admissions for mental disorders: two years of clinical experience.

Objectives: This retrospective study, conducted in Turin, Italy, between January 2021 and February 2023, investigates the impact of seasonal heatwaves on emergency department (ED) admissions for mental disorders.

Methods: Through the analysis of data from 2,854 patients, this research found a significant link between the occurrence of heatwaves, especially from June to August, and an elevated rate of ED admissions for psychiatric conditions.

Results: The data indicate a clear seasonal pattern, with admissions peaking during the hot months and diminishing in the colder months.

Cyclic voltammetry and chronoamperometry: mechanistic tools for organic electrosynthesis.

Electrochemical methods offer unique advantages for chemical synthesis, as the reaction selectivity may be controlled by tuning the applied potential or current. Similarly, measuring the current or potential during the reaction can provide valuable mechanistic insights into these reactions. The aim of this tutorial review is to explain the use of cyclic voltammetry and chronoamperometry to interrogate reaction mechanisms, optimize electrochemical reactions, or design new reactions.

Lung ultrasound: are we diagnosing too much?

The clinical use of lung ultrasound (LUS) has made more efficient many diagnostic processes at bedside. The great power of LUS is a superior diagnostic sensitivity in many applications, when compared to chest radiography (CXR). The implementation of LUS in emergency is contributing to reveal a growing number of radio-occult pulmonary conditions.

Feasibility of a New Lung Ultrasound Protocol to Determine the Extent of Lung Injury in COVID-19 Pneumonia.

Background: Lung ultrasound (LUS) scanning is useful to diagnose and assess the severity of pulmonary lesions during COVID-19-related ARDS (CoARDS). A conventional LUS score is proposed to measure the loss of aeration during CoARDS. However, this score was validated during the pre-COVID-19 era in patients with ARDS in the ICU and does not consider the differences with CoARDS.

Retrospective analysis of the application of CT scan in the emergency department to screen clinically asymptomatic COVID-19 before hospital admission.

Background: The necessity to identify and isolate COVID-19 patients to avoid intrahospital cross infections is particularly felt as a challenge. Clinically occult SARS-CoV-2 infection among patients admitted to the hospital is always considered a risk during the pandemic. The aim of our study is to describe the application of CT scan to reveal unexpected COVID-19 in patients needing hospital admission.

Photoredox-Catalyzed Synthesis of α-Amino Acid Amides by Imine Carbamoylation.

An operationally simple protocol for the photocatalytic carbamoylation of imines is reported. Easily available, bench-stable 4-amido Hantzsch ester derivatives serve as precursors to carbamoyl radicals that undergo rapid addition to -aryl imines. The reaction proceeds under blue light irradiation in the presence of the photocatalyst 3DPAFIPN and Brønsted/Lewis acid additives.

Are Lung Ultrasound Findings in COVID-19 Pneumonia Typical or Specific?

The application of point-of-care lung ultrasound (LUS) in the first diagnosis and management of Corona Virus Disease 2019 (COVID-19) has gained a great interest during a pandemic that is undermining even the most advanced health systems. LUS demonstrated high sensitivity in the visualization of the interstitial signs of the typical pneumonia complicating the infection. However, although this disease gives typical lung alterations, the same LUS signs observed in COVID-19 pneumonia can be detected in other common pulmonary conditions.

Emergency room comprehensive assessment of demographic, radiological, laboratory and clinical data of patients with COVID-19: determination of its prognostic value for in-hospital mortality.

Mortality risk in COVID-19 patients is determined by several factors. The aim of our study was to adopt an integrated approach based on clinical, laboratory and chest x-ray (CXR) findings collected at the patient's admission to Emergency Room (ER) to identify prognostic factors. Retrospective study on 346 consecutive patients admitted to the ER of two North-Western Italy hospitals between March 9 and April 10, 2020 with clinical suspicion of COVID-19 confirmed by reverse transcriptase-polymerase reaction chain test (RT-PCR), CXR performed within 24 h (analyzed with two different scores) and recorded prognosis.

Descriptive analysis of a comparison between lung ultrasound and chest radiography in patients suspected of COVID-19.

Background: Lung ultrasound (LUS) and chest radiography (CXR) are the most used chest imaging tools in the early diagnosis of COVID-19 associated pneumonia. However, the relationship between LUS and CXR is not clearly defined. The aim of our study was to describe the comparison between LUS interpretation and CXR readings in the first approach to patients suspected of COVID-19.

Heterogeneity of the bone marrow niche in patients with myeloproliferative neoplasms: ActivinA secretion by mesenchymal stromal cells correlates with the degree of marrow fibrosis.

Mesenchymal stromal cells (MSCs) represent an essential component of the bone marrow (BM) niche and display disease-specific alterations in several myeloid malignancies. The aim of this work was to study possible MSC abnormalities in Philadelphia-negative myeloproliferative neoplasms (MPNs) in relationship to the degree of BM fibrosis. MSCs were isolated from BM of 6 healthy donors (HD) and of 23 MPN patients, classified in 3 groups according to the diagnosis and the grade of BM fibrosis: polycythemia vera and essential thrombocythemia (PV/ET), low fibrosis myelofibrosis (LF-MF), and high fibrosis MF (HF-MF).

Correlation between CT findings and thoracoscopic diagnosis in diffuse pleural disease.

Objective: Computed Tomography (CT) is considered part of the routine diagnostic workup for pleural malignancy. The definitive diagnosis of pleural malignancy depends upon histological confirmation by pleural biopsy. The aim of this study is to assess the sensitivity and specificity of CT, in view of the latest imaging technologies, in detecting pleural malignancy compared to definitive histology achieved via thoracoscopy (VATS).

Aryl Pyrazoles from Photocatalytic Cycloadditions of Arenediazonium.

A photocatalytic synthesis of 1,5-diaryl pyrazoles from arenediazoniums and arylcyclopropanols is reported. The reaction proceeded under mild conditions (rt, 20 min) with catalytic [Ru(bpy)] under blue-light irradiation and exhibited compatibility with several functional groups (e.g.

Photoredox-Catalyzed Addition of Carbamoyl Radicals to Olefins: A 1,4-Dihydropyridine Approach.

Functionalization with C1-building blocks are key synthetic methods in organic synthesis. The low reactivity of the most abundant C -molecule, carbon dioxide, makes alternative carboxylation reactions with CO -surrogates especially important. We report a photoredox-catalyzed protocol for alkene carbamoylations.

Catalyst-Free -Deoxygenation by Photoexcitation of Hantzsch Ester.

A mild and operationally simple protocol for the deoxygenation of a variety of heteroaryl -oxides and nitroarenes has been developed. A mixture of substrate and Hantzsch ester is proposed to result in an electron donor-acceptor complex, which upon blue-light irradiation undergoes photoinduced electron transfer between the two reactants to afford the products. -oxide deoxygenation is demonstrated with 22 examples of functionally diverse substrates, and the chemoselective reduction of nitroarenes to the corresponding hydroxylamines is also shown.

"Sigmoid diverticulitis mimicking cholecystitis" a clinical challenge.

Diverticular disease is a common disorder and its incidence increases with ageing. Pathophysiology is multifactorial. Lifestyle, including smoking, alcohol intake, decreased dietary fibres and lack of physical activity, plays a predominant role.

Identification of CPE and GAIT elements in 3'UTR of macrophage migration inhibitory factor (MIF) involved in inflammatory response induced by LPS in Ciona robusta.

Innate immune responses face infectious microorganisms by inducing inflammatory responses. Multiple genes within distinct functional categories are coordinately and temporally regulated by transcriptional 'on' and 'off' switches that account for the specificity of gene expression in response to external stimuli. Mechanisms that control transcriptional and post-transcriptional regulation are important in coordinating the initiation and resolution of inflammation.

[Pulmonary tuberculosis in diagnostic imaging: the great mime.].

Pulmonary tuberculosis (TB) is nowadays one of the most common causes of infectious disease-related morbility and mortality worldwide. The differential diagnosis between TB and some others conditions is an emerging problem, particularly challenging when TB imaging mimicks sarcoidosis, lymphoproliferative disorders and pulmonary neoplasms. In these cases, the correct diagnoses can be made with certainty only with trans-bronchial or CT guided biopsy.
