News About the Extracellular Vesicles from Mesenchymal Stem Cells: Functions, Therapy and Protection from COVID-19
Succinate Accumulation Links Mitochondrial MnSOD Depletion to Aberrant Nuclear DNA Methylation and Altered Cell Fate
Journal of Experimental Pathology explores new advancements and novel discoveries in the field of molecular and cellular pathology. Pathology is one of the promising fields of medicine that help in improving the understanding of pathophysiology and diagnostic approaches of various diseases. Current medical practices need huge alterations to overcome the emerging disease outbreaks and improve the public health.
Concurrent PIK3CA and TERT Mutation Promote the Proliferation and Invasion of Thyroid Carcinoma Cells and may be Caused by Up-regulating the Expression of GABPA/GABPB1
Our previous research demonstrated that TERT and concurrent PIK3CA mutations predict worse overall survival in patients with poorly differentiated thyroid carcinoma and anaplastic thyroid carcinoma. However, the molecular mechanism underlying the synergistic oncogenic operations of the two oncogenes is unclear.
Current Understanding and Gaps in Knowledge of Chlamydia trachomatis Infection
Chlamydia trachomatis is a bacterial infection that most frequently causes sexually transmitted infection in the world, therefore, it is considered a serious public health problem. The objective of this commentary is to describe in a condensed but sufficient manner what has been reported by researchers on the subject based on the documentary review available in digital repositories on aspects of the infection.
Evaluation of Antimicrobial Potential of Endophytic Fungi and GC-MS Metabolic Profiling of Cephalosporium sp., and Fusarium moniliforme
From last few decades, microbes gained special attention residing inside plant tissues, now called endophyte. Studies proved that these microbes are able to produce biologically active metabolites and effective candidates against various pathogens. Endophytic fungi are a source of natural therapeutic products. Therefore, endophytic Fusarium species are isolated from different plants.
Cancer Stem Cells, Together with Mesenchymal Stem Cells and Other Cooperative Cells, Govern the Initiation and Development of Cancer
Until the end of last century, the origin and development of cancers were mostly attributed to the proliferation of their active cells, operative in collaboration with non-cancer cells of the patients. In particular, an important role was attributed to cells now recognized as mesenchymal stem cells (MSCs), first considered a few decades ago. Initially, however, the role attributed to these cells was only limited.
Varying Presentations of EBV-associated Clinical Entities with Emphasis on EBV-Associated T- and NK-cell Lymphoproliferative Disorders of Childhood
The Epstein-Barr Virus (EBV) is an endemic human herpesvirus, with 90% of people demonstrating serological evidence of prior exposure to EBV. In most cases, primary infections of EBV generate mild or asymptomatic clinical courses, but may present as infectious mononucleosis if contracted during young adulthood. In a small percentage of cases, Epstein- Barr virus infection may manifest as a noncanonical reaction, yielding a wide variety of clinical manifestations.
Epidemiological Profile and Clinical Conditions of Women with or without Precursor Lesion for Cervical Cancer
Cervical cancer (CC) is a health condition faced by women, and affects mainly developed countries [1,2]. According to the world estimate of 570 thousand new cases, cervix cancer is on the fourth place of most frequent cases, representing 3.2% of all cancer types, and is also on the fourth place regarding mortality [1]. The 2018 estimate was 311,365 deaths worldwide. This corresponds to an estimated risk of 15.1 per thousand women [3,4].
BNT162b2 mRNA COVID-19 Vaccine Elicited Antibody Responses in COVID-19-naïve Subjects
Coronavirus disease 19 (COVID-19) mRNA vaccines have gained international acceptance and have been proven to be safe and effective [1,2]. In a study of 3,950 frontline healthcare workers with no previous laboratory documentation of COVID-19 [3],
Weight and Abdominal Adiposity Loss with Auricular Acupuncture – A Randomized Controlled Trial
According to the WHO, obesity has more than doubled since 1980 [1]. The reality, however, is that most of the world’s population live in places where overweight and obesity kill more people than underweight. In 2016, more than a third of adults worldwide were classified as overweight or living with obesity, as were 41 million children younger than 5 years [2].
Antifungal Effects of PC945, a Novel Inhaled Triazole, on Candida albicans Pulmonary Infection in Immunocompromised Mice
Candida spp. are often detected from fungal cultures or mycobiome analysis of respiratory secretions, but are not usually treated since, even if detected persistently, the presence is assumed to be benign colonization unless invasive candidiasis in deeply immunocompromised subjects is suspected.
Neuroprotective Effects of Khaya Anthotheca (Welw.) C.DC (Meliaceae) Decoction on Neurodegeneration Induced by Estrogen Depletion in Rats
The cortex, hippocampus, and amygdala are among the brain regions where estrogens may act to improve cognition, memory and mood. In these regions, estrogens have many beneficial effects, including neuroprotection, neurogenesis, as well as neurotrophic, antioxidant, and anti-inflammatory effects [1-2].

Identification of Laryngotracheal Stenosis During Weaning from Tracheostomy – A Clinical Conundrum
Tracheostomy insertion is a common procedure used to support weaning from mechanical ventilation or following head and neck surgery. Resolution of the clinical need for tracheostomy is followed by a process of tracheostomy weaning and subsequent decannulation.
Adenosarcoma of Uterus with Sarcomatous Overgrowth and Rhabdomyoblastic Differentiation - A Rare Pathological Entity
Uterine adenosarcoma is a rare malignancy. It is defined as a biphasic tumor composed of both sarcomatous stroma and benign epithelial components. When the sarcomatous component occupies more than 25 % of the tumor then it is referred to as the sarcomatous overgrowth which accounts to about 10% of uterine adenosarcoma cases [1].

Application of Encapsulated Probiotics in Health Care
Probiotics are generally defined as nonpathogenic living organisms that have beneficial effects on host health. The term “probiotic” means “for life” that is derived from Greek language. At first, probiotics was defined as substances that are produced with microorganisms and promote the other microorganisms.

Spinal Capillary and Cavernous Haemangiomas in Developmental Age: Our Experience
Vascular anomalies are quite common lesions. They are frequently encountered in the pediatric population, being present at birth or developing later, during infancy, childhood, or adolescence. Most of these lesions are benign. Nevertheless, even benign lesions may exhibit significant morbidity without idoneous management [1].

News About the Extracellular Vesicles from Mesenchymal Stem Cells: Functions, Therapy and Protection from COVID-19
The present Commentary is a critical follow-up of a previous review about “Extracellular vesicles, news about their role in immune cells: physiology, pathology and diseases”, appeared in Clinical and Experimental Immunology last June 2019 [1].
Mechanistic and Translational Advances Using iPSC-Derived Blood Cells
The human induced pluripotent stem cell (iPSC) technology was developed more than ten years ago and has provided important tools for the mechanistic and cellular interrogation of many diseases [1]. To generate iPSC lines, somatic cells are reprogrammed into cells resembling embryonic stem cells by the overexpression of key transcription factors.
Succinate Accumulation Links Mitochondrial MnSOD Depletion to Aberrant Nuclear DNA Methylation and Altered Cell Fate
Epigenetic processes provide a mechanism for integrating metabolic inputs and translating them into various phenotypic outputs [1,2]. Indeed, epigenetic modifiers often require or are inhibited by key citric acid cycle (CAC) metabolites (e.g. succinate,
