Fabrication of a microfluidic device for probiotic drug's dosage screening: Precision Medicine for Breast Cancer Treatment.

Transl Oncol

August 2023

Research Unit of Medical Imaging, Physics and Technology, Faculty of Medicine, University of Oulu, Oulu, Finland. Electronic address:

Breast cancer is the most common cancer in women; it has been affecting the lives of millions each year globally and microfluidic devices seem to be a promising method for the future advancements in this field. This research uses a dynamic cell culture condition in a microfluidic concentration gradient device, helping us to assess breast anticancer activities of probiotic strains against MCF-7 cells. It has been shown that MCF-7 cells could grow and proliferate for at least 24 h; however, a specific concentration of probiotic supernatant could induce more cell death signaling population after 48 h.

Bacterial Persister Cells (BPCs) are quiescent, slow-growing or growth-arrested phenotypic variants of normal bacterial cells that are transiently tolerant to antibiotics. It seems that persister cells are the main cause of the recurrence of various chronic infections. Stress response (RpoS-mediated), Toxin-Antitoxin (TA) systems, inhibition of ATP production, Reactive Oxygen Species (ROS), efflux pumps, bacterial SOS response, cell-to-cell communication and stringent response (ppGpp- mediated) are the primary potential mechanisms for persistence cell formation.

Article Synopsis
  • The study aimed to understand how both genetic and non-genetic factors affect warfarin therapy among Iranian patients, leading to the creation of a new dosing prediction algorithm.
  • Researchers analyzed 200 patients' DNA and clinical characteristics, finding specific genetic markers and non-genetic factors that influence daily warfarin doses.
  • The proposed dosing model explains over half of the variability in warfarin response and offers a more accurate dosing method for Iranian patients compared to existing algorithms.

Exosomes derived from cancer-associated fibroblasts mediate response to cancer therapy.

Crit Rev Oncol Hematol

May 2023

Department of Medical Biotechnology, School of Advanced Technologies in Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran; Medical Nanotechnology and Tissue Engineering Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Cancer-associated fibroblasts (CAFs) are the prominent stromal cell population in the tumor microenvironment (TME), which play an indispensable role in cancer progression and response to therapy. CAFs provide communication between tumor cells and surrounding cells by secreting soluble biomolecules and extracellular vesicles (EVs). Exosomes are small membrane-bound EVs that contain various cargos, including growth factors, non-coding RNAs (ncRNAs), cytokines, and chemokines.

Article Synopsis
  • The INSPIRATION-S trial investigated the effects of atorvastatin versus placebo on 90-day outcomes in ICU patients with COVID-19, focusing on complications like thrombosis and mortality.
  • Results showed that atorvastatin users had a slightly lower incidence of severe outcomes compared to placebo (33.1% vs 38.0%), but the difference was not statistically significant.
  • The study indicated a potential benefit of atorvastatin, particularly for patients who began treatment within the first week of symptom onset, with improved functional status noted, although definitive conclusions couldn't be made.

Background: Breast cancer is one of the most common malignancies in women, with one in 20 globally. Oncolytic viruses have recently been the first step in the biological treatment of cancer, either genetically engineered or naturally occurring. They increase specifically inside cancer cells and destroy them without damaging normal tissues or producing a host immune response against tumour cells or expressing transgenes.

Background & Objective: High prevalence of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus results in deleterious complications and morbidities related to both diseases. Thus, we aimed to investigate dietary and anthropometric risk factors for progression of Non-alcoholic Fatty Liver Disease (NAFLD) in diabetic people.

Methods: Anthropometric, and dietary intakes, and hepatic steatosis and fibrosis were assessed in two hundred participants with type two diabetes (T2DM).

The respiratory system was primarily considered the only organ affected by Coronavirus disease 2019 (COVID-19). As the pandemic continues, there is an increasing concern from the scientific community about the future effects of the virus on male and female reproductive organs, infertility, and, most significantly, its impact on the future generation. The general presumption is that if the primary clinical symptoms of COVID-19 are not controlled, we will face several challenges, including compromised infertility, infection-exposed cryopreserved germ cells or embryos, and health complications in future generations, likely connected to the COVID-19 infections of parents and ancestors.
