Abstract

Concomitant application of hyperthermia, bleomycin and irradiation led to a maximal effect, compared with findings in cells treated with a single or two modalities in vitro. The synergistic effect of the combination with hyperthermia and irradiation was exhibited in all layers of multicellular tumor spheroids (MTS). The combined effects of water-bath hypothermia at 42.5 degrees C for 30 min, 1/10 LD50 bleomycin iv, and 200 rad irradiation were also demonstrated in DDD strain male mice with Ehrlich ascites tumor. According to the results of in vitro and in vivo studies, hyperthermia combined with irradiation and chemotherapy was prescribed for patients with squamous cell carcinoma of the esophagus. The long term results were compared between two groups of patients treated with hyperthermo-chemo-radiotherapy and those treated with chemo-radiotherapy but not hyperthermia. The five year survival rates of patients with resectable carcinoma, given preoperative hyperthermo-chemo-radiotherapy or chemo-radiotherapy were 43.2% and 14.7%, respectively. As severe side effects in patients given hyperthermia were nil, this treatment deserves serious consideration when treating patients with a malignant lesion of the esophagus.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
