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.

Encouraging responses were observed in early clinical trials with ONC201. As ONC201 was unavailable in Europe, a compassionate use program supported by the French Authorities was launched for patients at progression after standard of care radiotherapy.

However, it has been associated with allergic responses and immune cell activation. Here, we investigate whether cow's milk consumption regulates gut-brain axis functions and affects patterns of behaviors in BALB/c mice, previously described by present low sociability, significant stereotypes, and restricted interest features.

We prospectively studied acute and long term MBD adaptation of LKD from two kidney transplant centers (São Paulo, Brazil and Miami, USA).
Methods: Renal function and MBD parameters longitudinally after kidney donation (baseline - D0, day 1, 14, 180 and 360 post-operatively) were measured in 74 patients (40 y, 73% female, 54% Brazilian).
Background: Despite the growing number of elderly kidney transplant (Ktx) recipients, few studies have examined the effects of immunosuppression on their lymphocyte profiles.
Methods: We evaluated the early conversion from mycophenolate sodium (MPS) to everolimus (EVL) after rabbit antithymocyte globulin (rATG) 2 mg/kg induction in elderly kidney recipients. Three groups of KTx patients were compared: (a) Young (n=20, 36 ± 7 y) receiving standard immunosuppression (Group A1) (prednisone, tacrolimus, and MPS), (b) Elderly (n=35, 65 ± 3 y) receiving standard immunosuppression (Group B1), and (c) Elderly (n=16, 65 ± 3 y) with early (mean 30 d) conversion from MPS to EVL (Group B2).
Background: Approaches to documenting the software patterns of a system can support intentionally and manually documenting them or automatically extracting them from the source code. Some of the approaches that we review do not maintain proximity between code and documentation. Others do not update the documentation after the code is changed.

Pyruvate kinase M2 (PKM2) is a key glycolytic enzyme interacting with the inositol 1,4,5-trisphosphate receptor (IPR). This interaction suppresses IPR-mediated cytosolic [Ca] rises. As PKM2 exists in monomeric, dimeric and tetrameric forms displaying different properties including catalytic activity, we investigated the molecular determinants of PKM2 enabling its interaction with IPRs.

The late consequences of ZIKV persistence and whether new rounds of active replication can occur, remain unaddressed. Here, we investigated whether neonatally ZIKV-infected mice are susceptible to viral reactivation in adulthood.

This was a cross-sectional study conducted with individuals aged 4 to 18 years, diagnosed with primary neoplasms. Data was collected by using a questionnaire that assessed the degree of oral mucositis according to the World Health Organization index, the risk of oral mucositis according to the Child's International Mucositis Evaluation Scale, and depressive symptoms using the Children's Depression Inventory.

This disease is one of the main gynecological diseases, affecting around 10%-15% women and girls of reproductive age, being a common gynecologic disorder. Although endometriosis is a benign disease, it shares several characteristics with invasive cancer.

However, due to its complexity, it ranks 7th in the list of the most lethal cancers worldwide. The pathogenesis of PC involves several complex processes, including familial genetic factors associated with risk factors such as obesity, diabetes mellitus, chronic pancreatitis, and smoking.

Using microsatellites and mtDNA markers, we investigated its present genetic diversity and population structure. We also tested the hypothesis that this species currently hybridizes with the pampas fox (L.

Capsaicin 8% patch has arisen in the last decades as an alternative to oral drugs in the treatment of PNP with fewer side effects and promising results in efficacy.
Objectives: This work aims to evaluate the effectiveness of the topical application of capsaicin in PNP and its impact on patients' HRQoL based on the use of capsaicin in a tertiary hospital of Oporto.
There have been in the last three decades repeated publications indicating that the inositol 1,4,5-trisphosphate receptor (IPR) is regulated not only by cytosolic Ca but also by intraluminal Ca. Although most studies indicated that a decreasing intraluminal Ca level led to an inhibition of the IPR, a number of publications reported exactly the opposite effect, i.e.

To further investigate the physiological importance of the PKM2:IPR interaction, we developed and characterized HeLa PKM2 knockout (KO) cells. In the HeLa PKM2 KO cells, the release of Ca to the cytosol appears to be more sensitive to low agonist concentrations than in HeLa wild-type (WT) cells.

Gastric mucosa-associated lymphoid tissue lymphoma (GML) is a low-grade B-cell neoplasia frequently correlated with ()-induced chronic gastritis. On the other hand, a specific subset of individuals diagnosed with GML does not exhibit infection.

While adults suffered the highest morbidity and mortality rates of coronavirus disease 2019, children were thought to be exclusively asymptomatic or to present with mild conditions. However, around April 2020, there was an outbreak of a new clinical syndrome related to SARS-CoV-2 in children - multisystemic inflammatory syndrome in children (MIS-C) - which comprises a severe and uncon-trolled hyperinflammatory response with multiorgan involvement.

Inositol 1,4,5-trisphosphate receptors (IPRs) play a pivotal role at such contact sites, participating in both ER-mitochondria tethering and as Ca-transport system that delivers Ca from the ER towards mitochondria. At the ER-mitochondria contact sites, the IPRs function as a multi-protein complex linked to the voltage-dependent anion channel 1 (VDAC1) in the outer mitochondrial membrane, via the chaperone glucose-regulated protein 75 (GRP75).

Clinical practice guidelines currently recommend eradication as the preferred initial treatment for early-stage GML. To determine the practical effect of bacterial eradication as the sole initial therapy for early-stage GML, an updated analysis and review of available evidence is imperative.
