Advances in stem cell therapy in Alzheimer's disease: a comprehensive clinical trial review.

Alzheimer's disease (AD) is the most common type of dementia responsible for more than 121,499 deaths from AD in 2019 making AD the sixth-leading cause in the United States. AD is a progressive neurodegenerative disorder characterized by decline of memory, behavioral impairments that affects a person's ability to function independently ultimately leading to death. The current pressing need for a treatment for (AD) and advances in the field of cell therapy, has rendered stem cell therapeutics a promising field of research.

Immunotherapy for gastric cancer: a 2021 update.

Gastric cancer, the fifth most frequent cancer and the fourth leading cause of cancer deaths, accounts for a devastating death rate worldwide. Since the majority of patients with gastric cancer are diagnosed at advanced stages, they are not suitable for surgery and present with locally advanced or metastatic disease. Recent advances in immunotherapy have elicited a considerable amount of attention as viable therapeutic options for several cancer types.

Immunotherapy for gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs): a 2021 update.

Neuroendocrine neoplasms (NENs) are a group of heterogeneous malignancies, arising from the neuroendocrine system. These neoplasms are divided into two distinct groups, the low-proliferating, well-differentiated neuroendocrine tumors (NETs), and the highly-proliferating, poorly-differentiated neuroendocrine carcinomas (NECs). Recent data demonstrate that the incidence of gastroenteropancreatic (GEP) neuroendocrine neoplasms, GEP-NETs and GEP-NECs, has increased exponentially over the last three decades.
