In the study of mechanisms underlying its development attention has been paid to the microtubular network of its cells, mainly on βIII tubulin, considered as a marker of malignancy. In the present work, we chose to investigate the tubulin code in glioblastoma cells, analyzing the degree of interaction between tubulin post-translational modifications and different proteins associated with them. The pattern of diverse associated proteins such as EB-1, CLIP-170 and kinesin-1 and their degree of co-distribution with the most abundant post-translational tubulin modifications (tyrosination, acetylation and polyglutamylation) were evaluated. Through immunofluorescence we have shown that EB-1, CLIP-170 and kinesin-1 were well detectable in glioblastoma cells. The double fluorescence and colocalization index between the post-translational modifications of tubulin and associated proteins showed that tyrosinated α-tubulin has significantly high affinity with EB-1, CLIP-170 and kinesin-1, while for acetylated and polyglutamylated tubulin, the degree of interaction with the three associated proteins evaluated was less apparent. Data presented in this paper underline the importance of a thorough analysis of the microtubular mechanics in glioblastoma cells. This may suggest new experimental therapeutic approaches able to act more selectively on the microtubular network of cells in this type of cancer.We investigated whether lipoxin A4 (LXA4) inhibits the development of endometriosis by suppressing local estradiol synthesis. An endometriosis mouse model was constructed by surgical transplantation to subcutanous tissue sites. The treatment group received daily injections of LXA4 (10 μg/Kg) for 21days after which lesions were recovered. We measured 17β-HSD1, 17β-HSD2, CYP11A1, CYP19A1, CYP17A1, and estrogen receptor mRNA expression levels using real-time RT-PCR. In addition, immunohistochemistry was performed to determine protein expression and localization. After LXA4 administration, the volume of endometrial lesions was significantly reduced. Administration of LXA4 resulted in a more rudimentary architecture with a reduced number of developed glands surrounded by a small amount of stroma. LXA4 downregulated the mRNA and protein expression levels of 17β-HSD1, CYP11A1, CYP19A1, CYP17A1, ERα, and ERβ. Furthermore, LXA4 downregulated the expression of ERβ, aromatase expression, and 17β-HSD1 enzyme activity, which affected local estradiol production, resulting in reduced endometriosis. Results from our endometriosis mouse model showed that treatment with LXA4 reduced expression of enzymes and receptors associated or implicated with estrogen-dependent regulation of extra-uterine tissue. We believe that LXA4 has a potential therapeutic value for the treatment of endometriosis.India imposed one of the world's strictest population-wide lockdowns on March 25, 2020 for COVID-19. We estimated epidemiological parameters, evaluated the effect of control measures on the epidemic in India, and explored strategies to exit lockdown. We obtained patient-level data to estimate the delay from onset to confirmation and the asymptomatic proportion. We estimated the basic and time-varying reproduction number (R0 and Rt) after adjusting for imported cases and delay to confirmation using incidence data from March 4 to April 25, 2020. Using a SEIR-QDPA model, we simulated lockdown relaxation scenarios and increased testing to evaluate lockdown exit strategies. R0 for India was estimated to be 2·08, and the Rt decreased from 1·67 on March 30 to 1·16 on April 22. We observed that the delay from the date of lockdown relaxation to the start of the second wave increases as lockdown is extended farther after the first wave peak-this delay is longer if lockdown is relaxed gradually. Aggressive measures such as lockdowns may be inherently enough to suppress an outbreak; however, other measures need to be scaled up as lockdowns are relaxed. Lower levels of social distancing when coupled with a testing ramp-up could achieve similar outbreak control as an aggressive social distancing regime where testing was not increased.

Since the beginning of the severe acute respiratory syndrome coronavirus 2 pandemic, there is a discussion about the severity of coronavirus disease-2019 (COVID-19) in comparison to infections with seasonal Influenza. The objective of this study was to compare clinical and demographic characteristics of German patients hospitalized for infection with either SARS-CoV-2 or Influenza.

This study used anonymized German healthcare claims data. Patients with a confirmed COVID-19 or Influenza diagnosis, for whom a complete hospital course was available (i.e., the patient was discharged or died in hospital) were included. The data set included detailed information on patient characteristics and hospital treatment. Patients were grouped according to whether they were transferred to the intensive care unit (ICU), received mechanical ventilation (MV), or had a severe course of the disease (SD). Charlson Comorbidity Index in the eight quarters prior to hospitalization and secondary diagnoses during hospitalization weality and worse clinical outcomes than Influenza. This was not attributable to demographic characteristics, preexisting comorbidities, or patient triage, because the German healthcare system had not reached its limits in the pandemic. Discussions suggesting that COVID-19 and seasonal Influenza have similar severity cannot be based on clinical evidence.

COVID-19 resulted in higher inhospital mortality and worse clinical outcomes than Influenza. This was not attributable to demographic characteristics, preexisting comorbidities, or patient triage, because the German healthcare system had not reached its limits in the pandemic. Discussions suggesting that COVID-19 and seasonal Influenza have similar severity cannot be based on clinical evidence.A new strain belonging to the genus Kocuria, designed PT10, was isolated from irradiated roots of the xerophyte Panicum turgidum. Isolate PT10 is a Gram-positive, coccoid, aerobic and ionizing-radiation (IR)-resistant actinobacterium. PT10 has shown an ability to survive under extreme conditions, such as gamma irradiation, desiccation and high concentration of hydrogen peroxide. Phenotypic, chemotaxonomic and comparative genome analyses support the assignment of strain PT10 (LMG 31102 = DSM 108617) as Kocuria rhizophila. The complete genome sequence of PT10 consists of one chromosome (2,656,287 bps), with a 70.7% G + C content and comprises 2481 protein-coding sequences. A total of 1487 proteins were identified by LC-MS/MS profiling. In silico analyses revealed that the proteome of the oxidation-tolerant PT10 possesses several features explaining its IR-resistant phenotype and many adaptive pathways implicated in response to environmental pressures - desiccation, cold, reactive oxygen species and other stressors.Head and neck squamous cell carcinoma (HNSCC) is a malignant tumor of the upper aerodigestive tract. The loss and gain of miRNA function promote cancer development through various mechanisms. RNA sequencing (RNA-seq) and miRNAs sequencing data from the Cancer Genome Atlas (TCGA) was used to show the dysfunctional miRNAs microenvironment and to provide useful biomarkers for miRNAs therapy. Seven miRNAs were found to be independent prognostic factors of HNSCC patients in the training cohort. A total of 60 target genes for these miRNAs were predicted. Nine target genes (CDCA4, CXCL14, FLNC, KLF7, NBEAL2, P4HA1, PFKM, PFN2 and SEPPINE1) were correlated with patient's overall survival (OS) outcomes. We identified novel miRNAs markers for the prognosis of head and neck squamous cell carcinoma.Arthrobacter is a dominant aerobic bacterium under the class Actinobacteria, known for its nutritionally versatile nature and wide prevalence in stressful environments. In the current study representative two strains of Arthrobacter, ERGS101 and ERGS406, with efficient survivability under high altitude stress conditions were selected for comparative genomic studies with their mesophilic counterparts. Physiological analysis and genome insights supported the survival of these strains under multiple high-altitude stress conditions. Molecular cold-adaptation and substitution analysis of the studied strains supported the incidence of more cold-adapted proteins for functionality at low temperatures. Studied strains preferred amino acids like serine, asparagine, lysine, tryptophan for favoring increased flexibility supporting their broad temperature survivability. To the best of our knowledge, this is the first molecular cold adaptation analysis performed for the genus Arthrobacter and has revealed that 'aromaticity', one of the cold-adaptor indicators, should be carefully considered while evaluating cold adaptation strategies in psychrotrophic/psychrophilic bacteria.

Immunecheckpoint inhibitor (ICI)-mediated psoriasis poses significant diagnostic and therapeutic challenges.

Toreport data on ICI-mediated psoriasis, emerging from the largest cohort to date, to our knowledge, and to propose a step-by-step management algorithm.

The medical records of all patients with ICI-mediated psoriasis were retrospectively reviewed across 9 institutions.

We included a cohort of 115 individuals. Grade 1, 2, and 3 disease severity was reported in 60 of 105 (57.1%, 10 missing data), 34 of 105 (32.4%), and 11 of 105 (10.5%), respectively. The ratio between exacerbation and de novo cases was 14.3. The most common systemic therapy was acitretin (23 patients, 20.1%), followed by systemic steroids (8 patients, 7%), apremilast (7 patients, 6.1%), methotrexate (5 patients, 4.3%) and biologics (4 patients, 3.6%). Overall, 29 of 112 patients (25.9%) interrupted and 20 of 111 (18%) permanently discontinued ICIs because of psoriasis. Body surface area of greater than 10% at baseline had a 3.6 increased risk for ICI treatment modification (oddsratio, 3.64; 95% confidence interval, 1.27-10.45; P=.03) and a 6.4 increased risk for permanent discontinuation (odds ratio, 6.41; 95% confidence interval, 2.40-17.11; P<.001). Guttate psoriasis and grade 2 or 3 disease were significant positive predictors for antitumor response of ICI, whereas pruritus was a negative predictor.

Retrospective design.

Acitretin, apremilast, and methotrexate are safe and effective modalities for ICI-mediated psoriasis. In most cases, ICI can be completed unhindered. A therapeutic algorithm is proposed.
