CRISPR/Cas9 Eye Drop HSV-1 Treatment Reduces Brain Viral Load: A Novel Application to Prevent Neuronal Damage.

Herpes simplex virus-1 (HSV-1) can invade the central nervous system (CNS). However, antiviral drugs used to treat HSV-1 have significant toxicity and resistance. An alternative approach involves the use of the CRISPR/Cas9 complex as a viral replication inhibitor.

Evaluating the impact of performance status in elderly patients with glioblastoma.

Background: Glioblastoma (GBM) is a common brain tumor with a poor prognosis. There is a paucity of knowledge regarding optimal treatment approaches for elderly patients with GBM who have a relatively good Karnofsky (KPS) or Eastern Cooperative Oncology Group (ECOG) performance status. This study compared treatment outcomes in older patients (≥65) with GBM based on their performance status, either high (KPS ≥ 70 and ECOG < 2) or low (KPS < 70 and ECOG ≥ 2), who underwent hypofractionated radiotherapy (HFRT) (40 Gy in 15 fractions) versus conventional fractionation (60 Gy in 30 fractions).

Antibodies to the RBD of SARS-CoV-2 spike mediate productive infection of primary human macrophages.

The role of myeloid cells in the pathogenesis of SARS-CoV-2 is well established, in particular as drivers of cytokine production and systemic inflammation characteristic of severe COVID-19. However, the potential for myeloid cells to act as bona fide targets of productive SARS-CoV-2 infection, and the specifics of entry, remain unclear. Using a panel of anti-SARS-CoV-2 monoclonal antibodies (mAbs) we performed a detailed assessment of antibody-mediated infection of monocytes/macrophages.

Fungi associated with orange juice production and assessment of adhesion ability and resistance to sanitizers.

Orange juice is widely consumed worldwide due to its sensory and nutritional characteristics. This beverage is susceptible to contamination by acidic-tolerant microorganisms due to its low pH, especially filamentous fungi and yeasts. To minimize fungal spoilage, companies usually submit juice to thermal treatments; sanitizers are also applied on surfaces to maintain the microbiological quality.

Unbiased Drug Target Prediction Reveals Sensitivity to Ferroptosis Inducers, HDAC and RTK Inhibitors in Melanoma Subtypes.

Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem.

Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance.
