BACKGROUND: Several organizations have proposed guidelines or clinical decision tools for the management of patients with disorders of gut-brain interactions (DGBI) affecting the lower digestive tract including irritable bowel syndrome and chronic idiopathic constipation. Such algorithms are based on sequential therapeutic trials and modifying the treatment strategy based on efficacy and adverse events.
PURPOSE: The aims of this review are to evaluate the evidence for efficacy of second- and third-line pharmacotherapies and to assess the evidence for the alternative option to manage subgroups of patients with symptoms suggestive of lower DGBI based on diagnostic tests or documented dysfunctions. The preeminent tests to identify such subgroups that present with symptoms that overlap with lower DGBI are detailed: digital rectal examination as well as anorectal manometry and balloon expulsion for evacuation disorders, detailed measurements of colonic transit, and diagnosis of bile acid diarrhea or carbohydrate malabsorption based on biochemical measurements. The review also addresses the cost implications of screening to exclude alternative diagnoses and the costs of therapy associated with the therapeutic options following an algorithmic approach to treatment from the perspective of society, insurer, or patient. Finally, the costs of the diagnostic tests to identify actionable biomarkers and the evidence of efficacy of individualized therapy based on formal diagnosis or documentation of abnormal functions are detailed in the review.
Inflammation plays a crucial role in atherosclerosis and nonalcoholic fatty liver disease (NAFLD). We previously engineered a recombinant Lactococcus lactis strain expressing the Ling-Zhi immunomodulatory protein (L. lactis-LZ8). This study investigated the anti-atherosclerotic effects of L. lactis-LZ8 in rabbits fed a high-fat diet (HFD). Changes in body weight, serum lipid profiles, and liver function were monitored. The aorta and liver tissues were analyzed for gross pathology and histopathology. Eight-week administration of L. lactis-LZ8 with HFD ameliorated atherosclerosis by downregulating protein and gene expression associated with lipid metabolism and inflammation in the aortas. The rabbits receiving L. lactis-LZ8 exhibited a significant dose-dependent reduction in hepatic fat accumulation. RNA sequencing of the livers revealed that inflammatory genes in the L. lactis-LZ8 groups were downregulated compared to the HFD group. Disease ontology enrichment analysis indicated that these genes were involved in atherosclerosis. Gene set enrichment analysis plots revealed significant enrichment in the gene sets related to cholesterol homeostasis. CIBERSORT immune cell fraction analysis indicated significant infiltration by regulatory T cells, CD8+ T cells, activated dendritic cells, and natural killer cells in the L. lactis-LZ8 group. Our studies underscore LZ8's role in precision nutrition, providing a potential solution to the current challenges in modifying atherosclerosis and NAFLD.
BACKGROUND: Downy mildew is the most relevant disease of quinoa and the most widespread. Though, little is known about the genetics of resistance to this disease. The objective of this study was to identify the genomic regions controlling downy mildew resistance in quinoa and candidate genes for this trait. With this aim we carried out a GWAS analysis in a collection formed by 211 quinoa accessions from different origins. This approach was combined with inheritance studies and Bulk Segregant Analysis (BSA) in a segregating population.
RESULTS: GWAS analysis identified 26 genomic regions associated with the trait. Inheritance studies in a F2 population segregating for resistance revealed the existence of a major single dominant gene controlling downy mildew complete resistance in quinoa accession PI614911. Through BSA, this gene was found to be located in chromosome 4, in a region also identified by GWAS. Furthermore, several plant receptors and resistance genes were found to be located into the genomic regions identified by GWAS and are postulated as candidate genes for resistance.
CONCLUSIONS: Until now, little was known about the genetic control of downy mildew resistance in quinoa. A previous inheritance study suggested that resistance to this disease was a quantitative polygenic trait and previous GWAS analyses were unable to identify accurate markers for this disease. In our study we demonstrate the existence of, at least, one major gene conferring resistance to this disease, identify the genomic regions involved in the trait and provide plausible candidate genes involved in defense. Therefore, this study significantly increases our knowledge about the genetics of downy mildew resistance and provides relevant information for breeding for this important trait.
During surgical operations within the brain such as the removal of a tumor, electrodes are commonly used to map specific brain functions or monitor brain activity. These are most commonly flexible plastic devices with embedded metallic contacts that allow electrical activity in the brain to be detected and measured. They may also be used to stimulate precise areas of the brain to either trigger or block a response such as the contraction of a muscle. This allows the surgeon to define which regions of the brain are involved in controlling critical functions such as movement or speech so that these areas can be protected during the operation.

There remain limitations with the design and physical characteristics of commercially available electrodes for use during brain operations. These include the limited ability of conventional materials to fold over the complex shape of the brain and the need to use comparatively large metallic contacts to detect the tiny electrical signals. This study will be the first to introduce a new generation of electrodes which have been designed to overcome these limitations. They are extremely thin and flexible allowing them to follow the surface of the brain and to be used in locations within and around the brain for which the standard electrodes are unsuitable. The contact surfaces that detect electrical activity and enable and stimulate the brain have been replaced with graphene which is a novel carbon-based material. The use of graphene allows electrodes to be made that are more sensitive to the tiny electrical signals of the brain. This means that they can be much smaller and closer together providing increased detail in the recording and potentially enabling signals to be detected that would previously have required such long recordings that they could not be used to guide decision making during surgery.
Acute lymphoblastic leukemia (ALL) is highly associated with central nervous system (CNS) infiltration and can be associated with higher risk of relapse. Conventional cytology (CC) is the traditional method for diagnosing CNS infiltration, although the use of immunophenotyping by flow cytometry (FC) has gained prominence in recent years due to its higher sensitivity. Also, some authors have proposed that CSF contamination by a traumatic lumbar puncture (TLP) could have a clinical impact. This retrospective study accessed the impact of CNS infiltration by CC or FC on overall survival, event-free survival, and relapse rate. In a cohort of 105 newly diagnosed ALL patients, CNS1, CNS2, and CNS3 status were found in 84%, 14%, and 2%, respectively. We found that extramedullary disease at the diagnosis, higher leukocyte counts, and higher blast percentage were associated with a positive CC. Sensitivity and specificity of CC were 53% and 98%, respectively. Three-year overall survival was 42.5%. Conversely, TLP was not associated with a positive CC nor had an impact on relapse rates. In multivariate analysis, a positive CC was associated with an increased relapse rate (HR 2.074, p = 0.037), while its detection by FC did not associate with this endpoint. Survival rates seem to be increasing over the last years by the adoption of a stratified CNS prophylaxis risk strategy. CSF contamination does not represent a major concern according to our report, as it did not increase CNS involvement or relapse rates.
Overview of study design Open label clinical trial of persons (adults) that will determine the safety and efficacy of the diet supplement oral mitoquinone/mitoquinol mesylate (Mito-MES) to prevent the development and progression of severe viral infections like COVID-19 after high-risk exposure to a person with possible respiratory viral infection such as SARS-CoV-2 infection in persons who will receive Mito-MES compared to persons who will not receive Mito-MES (controls). A study participant will have the option to enroll either in the treatment arm or the control arm (no intervention but will complete relevant questionnaires and study procedures).

Efficacy: To determine the efficacy of the treatment with mito-MES 20 mg daily for up to 14 days compared to no treatment with mito-MES to prevent development of severe clinical symptoms of any viral infection in high-risk close household contacts of cases with viral infection. Viral infection will be defined clinically based on history obtained by the investigator who is an infectious diseases physician and stringent criteria will be followed. Viral infection will be defined as presence of at least two new onset independent symptoms or signs (fever) of respiratory disease that cannot be attributed to bacterial cause (for example the combination of runny nose and sore throat is very characteristic of a viral illness). The combination of fever and cough is not specific enough presentation since it can be attributed also to bacterial bronchitis or pneumonia. A study participant with chronic allergies or chronic sinusitis or asthma will not be included in the study.
Idiopathic inflammatory myopathies (IIMs) are systemic autoimmune diseases characterised by muscle weakness. Although multiple physiological and pathological processes are associated with IIMs, T-lymphocyte infiltration into muscle plays a key role in the development and exacerbation of IIMs. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a key transcription factor that regulates inflammatory responses; therefore, muscle Nrf2 may serve an important role in the development of IIMs. In this study, we demonstrated that experimental autoimmune myositis (EAM) causes loss of muscle mass and function in oxidative and glycolytic muscles in C57BL/6 mice. EAM increased CD4+ and CD8+ T-lymphocyte infiltration, as well as interferon-gamma (IFN-γ) and tumour necrosis factor-alpha (TNF-α) mRNA expression in oxidative soleus and glycolytic extensor digitorum longus muscles, along with elevated chemokine mRNA levels (i.e. CCL3, CCL5, CXCL9, CXCL10 and CXCL16). IFN-γ and TNF-α treatments increased the mRNA expression levels of these chemokines in C2C12 myotubes. EAM also increased phosphorylated Nrf2 at Ser40 in soleus and glycolytic white vastus lateralis muscle. Although the expression of several chemokines was affected by Nrf2 activation following tert-butylhydroquinone treatment or Keap1 knockdown, CCL5 mRNA expression significantly increased in C2C12 myotubes and mouse skeletal muscle. Moreover, muscle-specific Nrf2 knockout in mice attenuates EAM-induced loss of muscle mass and function, which was associated with the inhibition of CCL5 mRNA expression, CD8+ T-lymphocyte infiltration and IFN-γ mRNA expression. Collectively, these findings reveal that regulating Nrf2 activity is a promising therapeutic approach for treating IIM-mediated muscle weakness. KEY POINTS: Experimental autoimmune myositis (EAM) causes loss of muscle mass and function. Loss of muscle mass and function in EAM were associated with increased chemokine mRNA expression (i.e. CCL3, CCL5, CXCL9, CXCL10 and CXCL16), T-lymphocyte infiltration and inflammatory cytokine mRNA expression (i.e. IFN-γ and TNF-α) in the skeletal muscle. EAM activated Nrf2 in muscle and increased Nrf2 activity in vivo and in vitro increased CCL5 mRNA expression. Muscle-specific Nrf2 knockout in mice attenuated EAM-induced muscle weakness by inhibiting CCL5 mRNA expression, CD8+ T-lymphocyte migration and IFN-γ mRNA expression in muscles. These results provide further evidence for the potential therapeutic targeting of Nrf2 to mitigate EAM-induced muscle weakness.
Participants will start with 10 mg of cannabidiol daily and the dose will be escalated every third day until the maximum dosage of 50 mg is reached (after two weeks). The participants be on the 50 mg dosage of cannabidiol for 24 weeks.
Citalopram causes dose-dependent QTc prolongation an ECG abnormality that has been associated with Torsade de Pointes (TdP), ventricular tachycardia, and sudden death, all of which have been observed in postmarketing reports for citalopram [see Adverse Reactions 6.2)].

Because of the risk of QTc prolongation at higher citalopram doses, it is recommended that citalopram tablets not be given at doses above 40 mg once daily [see Dosage and Administration (2.1), Clinical Pharmacology (12.2)].

Citalopram should be avoided in patients with congenital long QT syndrome, bradycardia, hypokalemia or hypomagnesemia, recent acute myocardial infarction, or uncompensated heart failure unless the benefits outweigh the risks for a particular patient. Citalopram should also be avoided in patients who are taking other drugs that prolong the QTc interval [see Drug Interactions (7)]. Such drugs include Class 1A (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications, antipsychotic medications (e.g., chlorpromazine, thioridazine), antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong the QTc interval (e.g., pentamidine, levomethadyl acetate, methadone).

The citalopram dose should be limited in certain populations. The maximum dose should be limited to 20 mg once daily in patients who are CYP2C19 poor metabolizers or those patients receiving concomitant cimetidine or another CYP2C19 inhibitor, since higher citalopram exposures would be expected. The maximum dose should also be limited to 20 mg once daily in patients with hepatic impairment and in patients who are greater than 60 years of age because of expected higher exposures [see Dosage and Administration (2.3, 2.4), Drug Interactions (7), Use in Specific Populations (8.5), Clinical Pharmacology (12.3)].

Electrolyte and/or ECG monitoring is recommended in certain circumstances. Patients being considered for treatment with citalopram who are at risk for significant electrolyte disturbances should have baseline serum potassium and magnesium measurements with periodic monitoring. Hypokalemia (and/or hypomagnesemia) may increase the risk of QTc prolongation and arrhythmia, and should be corrected prior to initiation of treatment and periodically monitored. ECG monitoring is recommended in patients for whom citalopram use is not recommended unless the benefits clearly outweigh the risks for a particular patient (see above). These include those patients with the cardiac conditions noted above, and those taking other drugs that may prolong the QTc interval.

Discontinue citalopram tablets in patients who are found to have persistent QTc measurements >500 ms. If patients taking citalopram experience symptoms that could indicate the occurrence of cardiac arrhythmias, e.g., dizziness, palpitations, or syncope, the prescriber should initiate further evaluation, including cardiac monitoring.
BACKGROUND: Hypertrophic cardiomyopathy (HCM) is the most prevalent monogenic heart disorder. However, the pathogenesis of HCM, especially its nongenetic mechanisms, remains largely unclear. Transcription factors are known to be involved in various biological processes including cell growth. We hypothesized that SP1 (specificity protein 1), the first purified TF in mammals, plays a role in the cardiomyocyte growth and cardiac hypertrophy of HCM.
METHODS: Cardiac-specific conditional knockout of Sp1 mice were constructed to investigate the role of SP1 in the heart. The echocardiography, histochemical experiment, and transmission electron microscope were performed to analyze the cardiac phenotypes of cardiac-specific conditional knockout of Sp1 mice. RNA sequencing, chromatin immunoprecipitation sequencing, and adeno-associated virus experiments in vivo were performed to explore the downstream molecules of SP1. To examine the therapeutic effect of SP1 on HCM, an SP1 overexpression vector was constructed and injected into the mutant allele of Myh6 R404Q/+ (Myh6 c. 1211C>T) HCM mice. The human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) from a patient with HCM were used to detect the potential therapeutic effects of SP1 in human HCM.
RESULTS: The cardiac-specific conditional knockout of Sp1 mice developed a typical HCM phenotype, displaying overt myocardial hypertrophy, interstitial fibrosis, and disordered myofilament. In addition, Sp1 knockdown dramatically increased the cell area of hiPSC-CMs and caused intracellular myofibrillar disorganization, which was similar to the hypertrophic cardiomyocytes of HCM. Mechanistically, Tuft1 was identified as the key target gene of SP1. The hypertrophic phenotypes induced by Sp1 knockdown in both hiPSC-CMs and mice could be rescued by TUFT1 (tuftelin 1) overexpression. Furthermore, SP1 overexpression suppressed the development of HCM in the mutant allele of Myh6 R404Q/+ mice and also reversed the hypertrophic phenotype of HCM hiPSC-CMs.
CONCLUSIONS: Our study demonstrates that SP1 deficiency leads to HCM. SP1 overexpression exhibits significant therapeutic effects on both HCM mice and HCM hiPSC-CMs, suggesting that SP1 could be a potential intervention target for HCM.
Aneurysmal subarachnoid hemorrhage (SAH) is a devastating form of stroke affecting relatively young patients. It has an incidence of about 7 per 100,000. Associated economic costs are high. Treatment of the aneurysm to prevent rebleeding is the primary goal. Nevertheless, 3 to 12 days after the initial bleeding secondary ischemic changes occur in 30% of the patients. This delayed cerebral ischemia (DCI) remains the most important cause of mortality and morbidity in patients surviving aneurysm treatment.

Aneurysmal SAH exposes the brain to erythrocytes. Several days after the hemorrhage lysis of erythrocytes takes place and the brain is exposed to high concentrations of hemoglobin. Elevated hemoglobin concentrations are present not only at the basal surface of the brain, but also distributed around the brain and into deeper layers of the cortex. Heme is degraded by heme-oxygenase into carbon monoxide, biliverdin and iron. Free iron can react with H2O and O2- to form hydroxyl radicals (OH\*). The generation of hydroxyl radicals in this cascade, known as the Haber-Weiss or Fenton reaction, leads to extraction of hydrogen from unsaturated lipids in the cell membrane and initiates lipid peroxidation. Additionally it can exacerbate excitotoxicity by increased intracellular iron accumulation.

Iron chelators remove the excess of iron and are standard care in iron-overloaded patients. The use of iron chelators for SAH has been subject of animal studies with promising results on reduced vasospasm, oxidative stress, neuronal cell death and mortality. No clinical study for the use of deferoxamine in aneurysmal subarachnoid hemorrhage has been performed. A safety study for the use of Deferoxamine in patients in intracerebral hemorrhage (which is distinct from subarachnoid hemorrhage) has been performed. There were no associated serious adverse events or mortality, Deferoxamine is a chelator is used for more than 40 years in patients with iron overload diseases. This study investigates the safety and tolerability of deferoxamine versus placebo in patients with SAH for 3 consecutive days.
Process of making a cosmetic product based on soy lecithin for the treatment of cellulite. Especially conceived to obtain a cosmetic product of dermal or transdermal application of high efficiency in the anti-cellulite treatment, the procedure consists of incorporating all the sodium deoxycholate in deionized water, (approximately 2/3 of the total), previously boiled water, and shake until total dissolution of sodium deoxycholate. The soy lecithin is then added and stirred until a homogeneous dispersion is obtained. The benzyl alcohol is then added and stirred until the soya lecithin dissolves. Sodium metabisulphite is then added and stirred until it is completely dissolved to finally complete the mixture to the final volume with deionized water to obtain the final product.

An isolated HCV NS3 protein (I) or its portion, where at least one cysteine thiol group is irreversibly modified for use as a medicament, is new. ACTIVITY : Virucide. The purified NS3-TN SO3 and NS3-TN IAA proteins were diluted to 500 Microg/ml with 0.9% sodium chloride, mixed with an equal volume of Alhydrogel 1.3% and finally further diluted with 8 volumes of 0.9% sodium chloride to yield alum-adjuvanted NS3 (50 Microg NS3-Tn/ml) and Alhydrogel (0.13%). Groups of 6 Bal/c mice were immunized intramuscularly three times, with a three-week interval, with 5 Microg of either sulfonated or alkylated NS3. The immune response was assessed 2 weeks after the third immunization. All animals mounted an antibody response against NS3. Both the alkylated and the sulfonated protein included a significant antibody response, which was detected by alkylated or desulfonated protein in the enzyme linked immunosorbent assay (ELISA). MECHANISM OF ACTION : Vaccine (claimed).
Clear cell renal cell carcinoma (ccRCC) is characterized by Von Hippel Lindau (VHL) gene loss of function mutation, which leads to the accumulation of hypoxia-inducible factor 2α (HIF2α). HIF2α has been well-established as one of the major oncogenic drivers of ccRCC, however, its therapeutic targeting remains a challenge. Through an analysis of proteomic data from ccRCCs and adjacent non-tumor tissues, we herein revealed that Ubiquitin-Specific Peptidase 7 (USP7) was upregulated in tumor tissues, and its depletion by inhibitors or shRNAs caused significant suppression of tumor progression in vitro and in vivo. Mechanistically, USP7 expression is activated by the transcription factors FUBP1 and FUBP3, and it promotes tumor progression mainly by deubiquitinating and stabilizing HIF2α. Moreover, the combination of USP7 inhibitors and afatinib (an ERBB family inhibitor) coordinately induce cell death and tumor suppression. In mechanism, afatinib indirectly inhibits USP7 transcription and accelerates the degradation of HIF2α protein, and the combination of them caused a more profound suppression of HIF2α abundance. These findings reveal a FUBPs-USP7-HIF2α regulatory axis that underlies the progression of ccRCC and provides a rationale for therapeutic targeting of oncogenic HIF2α via combinational treatment of USP7 inhibitor and afatinib.
The first phase of the study is an Induction Phase; a known amount of each product (test and control) is applied, under a semi-occlusive patch. Patches will remain on the skin for 48 (±2) (weekdays) or 72 (±2) (including inclusive weekends) hours during this phase. Induction phase lasts for 3 weeks. After the Induction Phase participants will enter a Rest Phase of 2 weeks duration, during which no patches are applied. After the Rest Phase, participants will return to the clinical site for the Challenge Phase. In this phase a challenge patch containing the test and control products is applied to virgin skin for 48 (±2) hours then assessed 30 minutes (maximum 1 hour) following removal, 24 (± 2) and 48 (±2) hours later.
