Effect of spironolactone on pharmacological treatment of nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) was recently renamed to metabolic (dysfunction)-associated fatty liver disease (MAFLD) to better characterize its pathogenic origin. NAFLD represents, at least in western societies, a potential epidemic with raising prevalence. Its multifactorial pathogenesis is partially unraveled and till now there is no approved pharmacotherapy for NAFLD.

Does COVID-19 Vaccination Warrant the Classical Principle ""?

The current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic warrants an imperative necessity for effective and safe vaccination, to restrain Coronavirus disease 2019 (COVID-19) including transmissibility, morbidity, and mortality. In this regard, intensive medical and biological research leading to the development of an arsenal of vaccines, albeit incomplete preconditioned evaluation, due to emergency. The subsequent scientific gap raises some concerns in the medical community and the general public.

Soluble PD-L1 generated by endogenous retroelement exaptation is a receptor antagonist.

Immune regulation is a finely balanced process of positive and negative signals. PD-L1 and its receptor PD-1 are critical regulators of autoimmune, antiviral and antitumoural T cell responses. Although the function of its predominant membrane-bound form is well established, the source and biological activity of soluble PD-L1 (sPD-L1) remain incompletely understood.

Hookworms in Emergency Department: The ＂Vampire＂ Within.

Hookworms infection is a soil-transmitted helminthic disease particularly endemic in developing counties of tropical regions. It is attributed mainly to two human pathogens nematodes namely Necator americanus and Ancylostoma duodenale. Although the disease has been characterized as "neglected" is very diffi cult to be eliminated and the economic consequences are great.

Myeloid Neoplasms with Isolated Isochromosome 17q: a yet to be Defined Entity.

Myeloid neoplasms with isolated isochromosome 17q [MN i(17q)] has been described as a distinct entity with poor prognosis. However, literature reports show a considerable clinical and molecular heterogeneity. We describe a 58-year-old male patient who was diagnosed as refractory anemia with multilineage dysplasia and ringed sideroblasts with isolated i(17q).

Hyperhemolytic Syndrome Complicating a Delayed Hemolytic Transfusion Reaction due to anti-P1 Alloimmunization, in a Pregnant Woman with HbO-Arab/β-Thalassemia.

Background: Hyperhemolytic Syndrome or Hyperhemolytic Transfusion Reaction (HHTR), a life-threatening subset of Delayed Hemolytic Transfusion Reaction (DHTR) is characterized by destruction of both transfused and autologous erythrocytes evidenced by a fall in post transfusion hemoglobin below the pre-transfusion level.

Case Report: We describe a case of DHTR due to anti-P1 alloimmunization manifesting with hyperhemolysis in a 30-year-old Greek Pomak woman with thalassemia intermedia (HbO-Arab/β-thalassemia), during the11 week of her first gestation. She was successfully managed with avoidance of further transfusions and administration of IVIG and corticosteroids.

Adaptive Evolution Coupled with Retrotransposon Exaptation Allowed for the Generation of a Human-Protein-Specific Coding Gene That Promotes Cancer Cell Proliferation and Metastasis in Both Haematological Malignancies and Solid Tumours: The Extraordinary Case of MYEOV Gene.

The incidence of cancer in human is high as compared to chimpanzee. However previous analysis has documented that numerous human cancer-related genes are highly conserved in chimpanzee. Till date whether human genome includes species-specific cancer-related genes that could potentially contribute to a higher cancer susceptibility remains obscure.

Three-fold higher frequency of circulating chronic lymphocytic leukemia-like B-cell clones in patients with Ph-Myeloproliferative neoplasms.

Philadelphia chromosome-negative Myeloproliferative neoplasms (PhMPN) are accompanied by a markedly increased risk for development of chronic lymphocytic leukemia (CLL) compared to the general population. However, the pattern of onset and the biological characteristics of CLL in patients with coexistent PhMPN are highly heterogeneous rendering questionable if the above association reflects a causal relationship between the two disorders or merely represents a random event. By analyzing 82 patients with PhMPN and 100 age-matched healthy individuals we demonstrate that MPN patients have an almost threefold higher prevalence of, typically low-count, CLL-like monoclonal B lymphocytosis (MBL) compared to normal adults.

A case-control study on the rs3130932 single nucleotide polymorphism in the OCT4B translation initiation codon in association with cancer state.

A previously characterized single nucleotide polymorphism (rs3130932) in the translation initiation codon of the OCT4B isoform of the human OCT4 gene, ATG → AGG, is expected to hamper its expression in individuals carrying the AGG genotype. A case-control association study was conducted to validate the AGG genotype as a risk factor for tumour development. Blood samples were collected from 221 female patients with breast cancer, 100 female patients with ovarian cancer, 109 male patients with lung cancer and 553 age-matched and sex-matched healthy individuals.

OCT4B1 isoform: the novel OCT4 alternative spliced variant as a putative marker of stemness.

A novel OCT4 alternative spliced variant (OCT 4B1) is deduced to be the isoform present in 59 hESC lines characterised by the International Stem Cell Initiative (ISCI) rather than OCT4A as previously assumed. The new variant may be a more reliable marker of stemness than OCT4A and studies are needed to test this.

Revisiting OCT4 expression in peripheral blood mononuclear cells.

The transcription factor OCT4 (officially POU5F1; alternatively OCT3, OCT3/4, OTF3, and OTF4) is currently considered a main regulator of human embryonic stem cell pluripotency and self-renewal capacities. Importantly, these stemness properties are attributed to OCT4A, which is one of the two isoforms produced by the OCT4 gene. The second OCT4 isoform, OCT4B, does not share the stemness factor characteristics of OCT4A and is currently considered of unknown function.
