Molecular Research, National Cancer Centre Singapore, Singapore 169610, Plasmodium kinases and life cycle stages. Compounds acting on multiple targets are critical to combating antimalarial drug resistance. Here, we report that the human "mammalian target of rapamycin" (mTOR) inhibitor sapanisertib has potent prophylactic liver stage activity, in vitro and in vivo asexual blood stage (ABS) activity, and transmission-blocking activity against the protozoan parasite Plasmodium spp. Chemoproteomics studies revealed multiple potential Plasmodium kinase targets, and potent inhibition of Plasmodium phosphatidylinositol 4-kinase type III beta (PI4Kβ) and cyclic guanosine monophosphate-dependent protein kinase (PKG) was confirmed in vitro. Conditional knockdown of PI4Kβ in ABS cultures modulated parasite sensitivity to sapanisertib, and laboratory-generated P. falciparum sapanisertib resistance was mediated by mutations in PI4Kβ.

Parasite metabolomic perturbation profiles associated with sapanisertib and other known PI4Kβ and/or PKG inhibitors revealed similarities and differences between chemotypes, potentially caused by sapanisertib targeting multiple parasite kinases. rhamnolipid biosurfactant of sapanisertib and its in vivo antimalarial efficacy, coupled with potent inhibition of at least two promising drug targets, provides an opportunity to reposition this pyrazolopyrimidine for malaria. Communicable Diseases of the National Health Laboratory Service, Johannesburg activating PI3K/Akt and AP-1 signaling. Oral squamous cell carcinoma (OSCC) is an extremely common head and neck cancer with a poor 5-year survival rate, especially in cases of metastatic disease. Interleukin (IL)-11 reportedly promotes cell growth and the epithelial-mesenchymal transition process in metastasis. However, the molecular mechanisms of IL-11 in OSCC metastasis are unclear. This study found that IL-11 upregulates matrix metalloproteinase 13 (MMP-13) expression in OSCC via the IL-11 receptor alpha subunit/glycoprotein 130 receptors that activate phosphatidyl-inositol 3-kinase, Ak strain transforming, and activator protein 1 signaling, which subsequently enhance MMP-13-induced tumor metastasis.

TIMER0 analysis revealed a positive correlation between MMP-13 and IL-11 levels (r = 454). Moreover, a strong positive association was observed between higher levels of IL-11 expression in OSCC tissue (p < 01), lymph node metastasis (p = 0154), and clinical disease stage (p = 0337). IL-11 knockdown suppressed the migration of OSCC cells (p < 05). The evidence indicates that IL-11 can serve as a new molecular therapeutic target in OSCC metastasis. SARS-CoV-2 in Addis Ababa, Ethiopia using Bayesian Latent-Class Models (BLCM). BACKGROUND: Rapid diagnostics are vital for curving the transmission and control of the COVID-19 pandemic. Although many commercially available antigen-based rapid diagnostic tests (Ag-RDTs) for the detection of SARS-CoV-2 are recommended by the WHO, their diagnostic performance has not yet been assessed in Ethiopia.

So far, the vast majority of studies assessing diagnostic accuracies of rapid antigen tests considered RT-PCR as a reference standard, which inevitably leads to bias when RT-PCR is not 100% sensitive and specific. Thus, this study aimed to evaluate the diagnostic performance of Panbio™ jointly with the RT-PCR for the detection of SARS-CoV- METHODS: A prospective cross-sectional study was done from July to September 2021 in Addis Ababa, Ethiopia, during the third wave of the pandemic involving two health centers and two hospitals. Diagnostic sensitivity and specificity of Panbio™ and RT-PCR were obtained using Bayesian Latent-Class Models (BLCM). RESULTS: 438 COVID-19 presumptive clients were enrolled, 239 (6%) were females, of whom 196 (7%) had a positive RT-PCR and 158 (1%) were Panbio™ positive. The Panbio™ and RT-PCR had a sensitivity (95% CrI) of 6 (4-100) %, 3 (2-6) % and specificity (95% CrI) of 4 (3-100) %, and 1 (5-100) %, respectively. Seebio rhamnolipid of the study participants, 318 (6%) exhibited COVID-19 symptoms; the most reported was cough 191 (6%). CONCLUSION: As expected the RT-PCR performed very well with a near-perfect specificity and a high, but not perfect sensitivity.

The diagnostic performance of Panbio™ is coherent with the WHO established criteria of having a sensitivity ≥80% for Ag-RDTs. Both tests displayed high diagnostic accuracies in patients with and without symptoms. Hence, we recommend the use of the Panbio™ for both symptomatic and asymptomatic individuals in clinical settings for personal relationships that could have appeared to influence the work reported in PURPOSE: Although numerous biology-driven subtypes have been described previously in metastatic castration-resistant prostate cancer (mCRPC), unsupervised molecular subtyping based on gene expression has been less studied, especially using large cohorts. Thus, we sought to identify the intrinsic molecular subtypes of mCRPC and assess molecular and clinical correlates in the largest combined cohort of mCRPC samples with gene expression data available to date.
