  • The study aimed to evaluate the protective role of pregabalin (PRG) against kidney and renal endothelial damage caused by sepsis induced by lipopolysaccharide (LPS) in rats.
  • Results showed that LPS significantly worsened kidney function markers and increased oxidative stress, while adding PRG improved these markers and reduced inflammation and tissue damage.
  • The findings suggest that PRG may help mitigate sepsis-related kidney damage and indicate potential for its use in preventive treatment, although further research is needed.

Omalizumab is a biological drug targeting circulating IgE, approved for use in allergic asthma, chronic spontaneous urticaria, and recently for chronic rhinosinusitis with nasal polyps, with good efficacy in all these settings. Some concerns about omalizumab safety have been raised as its use has been recently linked to potential increased cancer risk. Nevertheless, literature evidence does not support this statement, and clinical studies and evidence from real-world registries and surveillance analysis have consistently reported drug safety.

The SARS-CoV-2 is a β-CoV, which is enveloped by non-segmented positive-stranded RNA virüs. When β-CoV infects the respiratory tract, it can cause mild and/or severe acute respiratory syndrome (SARS) with consequent release of cytokines/mediators, including interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8 (CXCL8), IL-10, IP10, IL-12, IL-13, IL-17, IL-33, IL-25, IL-37, IL-38, GCSF, GM-CSF, HGF, IP-10, MCP-1, MIP-1α (also known as CCL3), IFN-γ, IFN-α, TRAIL, MCSF, and TNF-α. Our hypothesis of writing this article can be summarized as; if the monoclonal antibody (mAb) administered by us does not inhibit the immune response for the β-CoV and inhibits uncontrolled-adaptive/hyperimmune responses (also called cytokine storm) on endothelium level, then it may cause severe coronavirus disease 2019 (COVID-19).

Both uterine serous carcinoma (USC) and ovarian serous carcinoma (OSC) are presented at advanced stage at the first admittion and dissseminated disease makes the anatomical site of the tumor origin imposible. CA125 and p53 are reliable markers that are useful for differentiating both uterine serous and ovarian serous carcinoma from their most common subtypes (endometrioid type carcinoma of ovary and uterus) but so far there is no histopathologic marker that differentiates USC from OSC. On the other hand, Trastuzumab (Herceptin) increases progression-free survival among USC patients, but not OSC patients and makes the histopathologically assigning the origin of the tumor important.

DNA methylation differences between normal tissue and cancerous tissue resulting in differential expression of genes are a hallmark of acute myeloid leukemia (AML) and can provide malignant cells with a growth advantage via silencing of specific genes, for example, transcription factors. Oligodendrocyte lineage transcription factor 2 (OLIG2) was reported to be differentially methylated and associated with prognosis in AML and, as reported for acute lymphoblastic leukemia and malignant glioma, may play a role in malignant transformation. We report that DNA methylation of OLIG2 is associated with decreased expression of mRNA in AML cell lines and patients.

CD200 is a novel immune-effective molecule, existing in a cell membrane-bound form, as well as in a soluble form in serum, which performs to modulate inflammatory and acquired immune responses. Autosomal dominant polycystic kidney disease (ADPKD) is characterized by the development of large renal cysts and progressive loss of renal function. As defects in cell cycle arrest and apoptosis of renal tubular epithelial cells occur in ADPKD, we asked whether serum soluble CD200 might underlie and effect on ADPKD.

Treatment with hypomethylating agents such as decitabine, which results in overall response rates of up to 50%, has become standard of care in older patients with acute myeloid leukemia (AML) who are not candidates for intensive chemotherapy. However, there still exists a lack of prognostic and predictive molecular biomarkers that enable selection of patients who are likely to benefit from epigenetic therapy. Here, we investigated distinct genetic (FLT3-ITD, NPM1, DNMT3A) and epigenetic (estrogen receptor alpha (ERα), C/EBPα, and OLIG2) aberrations in 87 AML patients from the recently published phase II decitabine trial (AML00331) to identify potential biomarkers for patients receiving hypomethylating therapy.
