Generation and characterization of two isogenic induced pluripotent stem cell lines from a young female with microcephaly carrying a compound heterozygous mutation in BUB1 gene.

Mutations in the Budding uninhibited by benzimidazoles (BUB1) gene were recently associated with neurodevelopmental disorders (Carvalhal et al., 2022). Here, we describe the generation and characterization of two induced pluripotent stem cells (iPSC) clones from a young female with microcephaly.

Ibero-American Consensus for the Management of Peritoneal Sarcomatosis: Updated Review and Clinical Recommendations.

Peritoneal sarcomatosis is a rare malignant disease with a poor prognosis, secondary to peritoneal dissemination of abdominopelvic soft tissue sarcomas. Its rarity, together with the characteristic histological heterogeneity and the historically poor response to systemic treatments, has prevented the establishment of widely accepted treatment criteria with curative intent. In this sense, radical cytoreductive surgery (CRS) with peritonectomy procedures and hyperthermic intraperitoneal chemotherapy (HIPEC), widely used in peritoneal carcinomatosis with excellent results, have not had the same evolutionary development in patients with peritoneal sarcomatosis.

Fish oil supplementation in obese rats ameliorates metabolic syndrome response.

Accumulation of visceral adipose tissue is associated with metabolic syndrome (MS), insulin resistance, and dyslipidemia. Here we examined several morphometric and biochemical parameters linked to MS in a rodent litter size reduction model, and how a 30-day fish oil (FO) supplementation affected these parameters. On day 3 post-birth, pups were divided into groups of ten or three.

How soon do metabolic alterations and oxidative distress precede the reduction of muscle mass and strength in Wistar rats in aging process?

Here we investigate metabolic changes, the antioxidant system and the accumulation of oxidative damage in muscles with different fiber types during the aging process in Wistar rats and try to map how sooner the changes occur. To do so, 30 male Wistar rats were submitted to behavioral evaluation to determine voluntary strength in the 11, 15, and 19 month old rats, measuring the energy metabolism, antioxidant system, oxidative damage and structure in the soleus and extensor digitorum longus muscles. We detected structural and metabolic changes in both muscles, especially in the EDL of 15 month old rats and in the soleus of 19 month old rats.

Regulation of Redox Profile and Genomic Instability by Physical Exercise Contributes to Neuroprotection in Mice with Experimental Glioblastoma.

Glioblastoma (GBM) is an aggressive, common brain cancer known to disrupt redox biology, affecting behavior and DNA integrity. Past research remains inconclusive. To further understand this, an investigation was conducted on physical training's effects on behavior, redox balance, and genomic stability in GBMA models.

European e-Delphi process to define expert consensus on electrochemotherapy treatment indications, procedural aspects, and quality indicators in melanoma.

Background: Skin metastases are an important co-morbidity in melanoma. Despite broad adoption, electrochemotherapy implementation is hindered by a lack of treatment indications, uncertainty regarding procedural aspects, and the absence of quality indicators. An expert consensus may harmonize the approach among centres and facilitate comparison with other therapies.

Non-invasive diagnosis of transthyretin cardiac amyloidosis utilizing typical late gadolinium enhancement pattern on cardiac magnetic resonance and light chains.

Aims: While cardiac magnetic resonance (CMR) is often obtained early in the evaluation of suspected cardiac amyloidosis (CA), it currently cannot be utilized to differentiate immunoglobulin (AL) and transthyretin (ATTR) CA. We aimed to determine whether a novel CMR and light-chain biomarker-based algorithm could accurately diagnose ATTR-CA.

Methods And Results: Patients with confirmed AL or ATTR-CA with typical late gadolinium enhancement (LGE) and Look-Locker pattern for CA on CMR were retrospectively identified at three academic medical centres.

"It is Typical of Teenagers": When Teachers Morally Disengage from Cyberbullying.

A first study analyze teachers' definitions of cyberbullying, how they would intervene and feel morally implicated with the phenomenon.

Cutaneous and subcutaneous Kaposi's sarcoma lesions treated with electrochemotherapy.

Background And Objectives: Kaposi's sarcoma (KS) is a locally aggressive mesenchymal tumor that involves the lymphovascular system, with a tendency to become multifocal. Electrochemotherapy (ECT) is considered a valuable treatment option in selected patients with cutaneous and subcutaneous KS lesions.

Methods: We report a retrospective study that included 14 classic and endemic KS patients that underwent ECT sessions for the treatment of KS cutaneous and subcutaneous lesions at our institution.

Safety and efficacy of electrochemotherapy in a series of patients with nonmetastasized primary or recurrent anorectal malignant melanoma.

Anorectal malignant melanoma (AMM) is a rare malignant tumor. Surgery remains the gold standard but new adjuvant treatments to allow local sphincter-saving are warranted. Electrochemotherapy (ECT) is an alternative to surgery in selected cohorts of patients.

Palliative Electrochemotherapy Treatment of Cutaneous Metastases in a Patient with Advanced Thyroid Papillary Carcinoma.

Advanced papillary thyroid carcinoma (PTC) with cutaneous metastases may cause pain, ulceration, and bleeding. Electrochemotherapy (ECT) is a minimally invasive treatment of tumors located in the skin and subcutaneous tissue. The electric pulses potentiate the toxicity of cytostatic agents entering the tumor cell.

Electrochemotherapy, a local treatment for squamous cell carcinoma in patients with recessive dystrophic epidermolysis bullosa.

Epidermolysis Bullosa (EB) is a rare group of diseases caused by genetic variants in skin structural proteins. EB is characterized by varying degrees of skin fragility, blisters and impaired wound healing, and is classified based on the ultrastructural levels of skin cleavage-simplex, junctional, dystrophic, and Kindler Syndrome. Squamous cell carcinoma (SCC) is the most severe complication and most common cause of death of patients with EB, particularly in those with recessive dystrophic Epidermolysis Bullosa (RDEB).

Effects of Exposure to Cola-Based Soft Drink on Bleaching Effectiveness and Tooth Sensitivity of In-Office Bleaching: A Blind Clinical Trial.

Objective: The purpose of this single-blind (evaluators) and parallel design study was to evaluate whether exposure to a cola-based soft drink during bleaching treatment with 35% hydrogen peroxide (HP) affects color change and bleaching-induced tooth sensitivity.

Material And Methods: Forty-four patients with central incisors darker than A2 were selected. Participants who did not drink cola-based soft drinks were assigned to the control group (CG), while participants who drank a cola-based soft drink at least twice a day were assigned to the experimental group (EG).

A quantitative analysis of cohesin decay in mitotic fidelity.

Sister chromatid cohesion mediated by cohesin is essential for mitotic fidelity. It counteracts spindle forces to prevent premature chromatid individualization and random genome segregation. However, it is unclear what effects a partial decline of cohesin may have on chromosome organization.

ALADIN is required for the production of fertile mouse oocytes.

Asymmetric cell divisions depend on the precise placement of the spindle apparatus. In mammalian oocytes, spindles assemble close to the cell's center, but chromosome segregation takes place at the cell periphery where half of the chromosomes are expelled into small, nondeveloping polar bodies at anaphase. By dividing so asymmetrically, most of the cytoplasmic content within the oocyte is preserved, which is critical for successful fertilization and early development.

Transitioning from anatomic landmarks to ultrasound guided central venous catheterizations: guidelines applied to clinical practice.

Introduction: Centrally inserted central catheter (CICC) insertion is a commonly performed procedure that may give rise to different complications. Despite the suggestion of guidelines to use ultrasound guidance (USG) for vascular access, not all centers use it systematically. The aim of this study is to illustrate the experience with ultrasound in CICC placement at a high-volume oncological center, in a country where the landmark technique is standard.

CDK-dependent phosphorylation of PHD1 on serine 130 alters its substrate preference in cells.

PHD1 (also known as EGLN2) belongs to a family of prolyl hydroxylases (PHDs) that are involved in the control of the cellular response to hypoxia. PHD1 is also able to regulate mitotic progression through the regulation of the crucial centrosomal protein Cep192, establishing a link between the oxygen-sensing and the cell cycle machinery. Here, we demonstrate that PHD1 is phosphorylated by CDK2, CDK4 and CDK6 at S130.

The nucleoporin ALADIN regulates Aurora A localization to ensure robust mitotic spindle formation.

The formation of the mitotic spindle is a complex process that requires massive cellular reorganization. Regulation by mitotic kinases controls this entire process. One of these mitotic controllers is Aurora A kinase, which is itself highly regulated.
