    Abstract The trace element zinc (Zn) displays a wide range of biological functions. Zn ions control intercellular communication and intracellular events that maintain normal physiological processes. These effects are achieved through the modulation of several Zn-dependent proteins, including transcription factors and enzymes of key cell signaling pathways, namely those involved in proliferation, apoptosis, and antioxidant defenses. Efficient homeostatic systems carefully regulate intracellular Zn concentrations. However, perturbed Zn homeostasis has been implicated in the pathogenesis of several chronic human diseases, such as cancer, diabetes, depression, Wilson's disease, Alzheimer's disease, and other age-related diseases. This review focuses on Zn's roles in cell proliferation, survival/death, and DNA repair mechanisms, outlines some biological Zn targets, and addresses the therapeutic potential of Zn supplementation in some human diseases.

    Abstract Resistance to chemo- and radiotherapy is a common event among cancer patients and a reason why new cancer therapies and therapeutic strategies need to be in continuous investigation and development. DNA damage response (DDR) comprises several pathways that eliminate DNA damage to maintain genomic stability and integrity, but different types of cancers are associated with DDR machinery defects. Many improvements have been made in recent years, providing several drugs and therapeutic strategies for cancer patients, including those targeting the DDR pathways. Currently, poly (ADP-ribose) polymerase inhibitors (PARP inhibitors) are the DDR inhibitors (DDRi) approved for several cancers, including breast, ovarian, pancreatic, and prostate cancer. However, PARPi resistance is a growing issue in clinical settings that increases disease relapse and aggravate patients' prognosis. Additionally, resistance to other DDRi is also being found and investigated. The resistance mechanisms to DDRi include reversion mutations, epigenetic modification, stabilization of the replication fork, and increased drug efflux. This review highlights the DDR pathways in cancer therapy, its role in the resistance to conventional treatments, and its exploitation for anticancer treatment. Biomarkers of treatment response, combination strategies with other anticancer agents, resistance mechanisms, and liabilities of treatment with DDR inhibitors are also discussed.

    Abstract The role of metalloproteinases (MMPs) in hematological malignancies, like acute myeloid leukemia (AML), myelodysplastic neoplasms (MDS), and multiple myeloma (MM), is well-documented, and these pathologies remain with poor outcomes despite treatment advancements. In this study, we investigated the effects of batimastat (BB-94), an MMP inhibitor (MMPi), in single-administration and daily administration schemes in AML, MDS, and MM cell lines. We used four hematologic neoplasia cell lines: the HL-60 and NB-4 cells as AML models, the F36-P cells as an MDS model, and the H929 cells as a model of MM. We also tested batimastat toxicity in a normal human lymphocyte cell line (IMC cells). BB-94 decreases cell viability and density in a dose-, time-, administration-scheme-, and cell-line-dependent manner, with the AML cells displaying higher responses. The efficacy in inducing apoptosis and cell cycle arrests is dependent on the cell line (higher effects in AML cells), especially with lower daily doses, which may mitigate treatment toxicity. Furthermore, BB-94 activated apoptosis via caspases and ERK1/2 pathways. These findings highlight batimastat's therapeutic potential in hematological malignancies, with daily dosing emerging as a strategy to minimize adverse effects.

    Abstract Carotid artery dissection causes 2.5% of ischemic acute strokes and is more common in younger rather than older patients. Extracranial lesions often manifest as transient and reversible neurological deficits until a stroke occurs. In this case, we describe a 60-year-old male patient with no known cardiovascular risk factors who experienced three transient ischemic attacks (TIAs) in four days while traveling in Portugal. At the emergency department, he was treated for an occipital headache associated with nausea and two episodes of decreased left upper-limb muscle strength lasting two to three minutes with spontaneous recovery. He requested discharge against medical advice so that he could travel home. During the return flight, he had a severe right parietal headache followed by decreased muscle strength in the left arm. After an emergency landing in Lisbon, he was referred to the local emergency department, where his neurological examination revealed preferential gaze to the right exceeding the midline, left homonymous hemianopsia, minor left central facial paresis, and spastic left brachial paresis. On the National Institutes of Health Stroke Scale, he scored 7. A head CT was performed, showing no acute vascular lesions (i.e., Alberta Stroke Program Early CT Score of 10). However, an image compatible with dissection was identified on CT angiography of the head and neck and confirmed by digital subtraction angiography. The patient underwent balloon angioplasty and placement of three stents in the right internal carotid artery with vascular permeabilization. This case highlights how prolonged and incorrect cervical posture and microtrauma secondary to aircraft turbulence may be associated with carotid artery dissection in predisposed individuals. The Aerospace Medical Association guidelines advocate that patients with a recent acute neurological event should avoid air travel until clinical stability is assured. As TIA is considered a harbinger of stroke, patients should be properly evaluated and avoid air travel for at least two days after the event.

    Abstract Lymphoid malignancies are a group of highly heterogeneous diseases frequently associated with constitutive activation of the nuclear factor kappa B (NF-κB) signaling pathway. Parthenolide is a natural compound used to treat migraines and arthritis and found to act as a potent NF-κB signaling inhibitor. This study evaluated in vitro parthenolide efficacy in lymphoid neoplasms. We assessed parthenolide metabolic activity in NCI-H929 (MM), Farage (GCB-DLBCL), Raji (BL), 697 and KOPN-8 (B-ALL), and CEM and MOLT-4 (T-ALL), by resazurin assay.

    Abstract Pinus pinea stands have been identified as one of the target species for agroforestry systems in Europe. Its fruit yield is of importance to the local development, especially in the Mediterranean basin, due to its highly nutritional kernels and its economic value. The objectives of this study were to analyze the relation between pine nut and kernel weight and its efficiencies in relation to cone and tree traits for different stand structures. The statistical analysis was carried out with correlation, multiple correlation analysis, hurdle-gamma regression, principal component and cluster analysis, with a dataset of about 3300 cones collected in four plots and 3 years. The results indicate that pine nut and kernel and its efficiencies depend on stand structure, year and tree characteristics. The principal component analysis and the cluster analysis enabled the identification of four groups of trees related to the pine nut and kernel efficiencies. The higher efficiencies per tree are attained in stands managed for fruit production, increasing with the decrease of the density.

    Abstract Acute lymphoblastic leukemia (ALL) is one of the most common hematological malignancies at pediatric ages and is characterized by different chromosomal rearrangements and genetic abnormalities involved in the differentiation and proliferation of lymphoid precursor cells. Brusatol is a quassinoid plant extract extensively studied due to its antineoplastic effect through global protein synthesis and nuclear factor erythroid 2-related factor-2 (NRF2) signaling inhibition. NRF2 is the main regulator of cellular antioxidant response and reactive oxygen species (ROS), which plays an important role in oxidative stress regulation. This study aimed to evaluate the effect of brusatol in in vitro models of ALL. KOPN-8 (B-ALL), CEM (T-ALL), and MOLT-4 (T-ALL) cell lines were incubated with increasing concentrations of brusatol, and the metabolic activity was evaluated using the resazurin assay. Flow cytometry was used to evaluate cell death, cell cycle, mitochondrial membrane potential (Δψ

    Abstract Osteogenesis imperfecta (OI) is a rare genetic disorder. Due to considerable phenotypic variability, a classification was developed for OI subtypes based on clinical features and disease severity. A seven-day-old female was born at 40+1 weeks of gestation whose mother received routine antenatal care and had an uneventful pregnancy. In delivery, the newborn suffered bilateral collarbone fractures. After a week, she returned to an unscheduled appointment at the healthcare family unit due to an inconsolable cry and pain during mobilization of the left lower limb with three days of evolution, which were noticed by her parents. On examination, she presented edema in the right coxofemoral joint, asymmetry in the folds, and inconsolable crying during the mobilization of both hip joints. She was sent to the emergency department, where a pelvis X-ray was performed revealing a bilateral fracture of the femurs. During hospitalization, a genetic study revealed pathogenic variants of the
