BACKGROUND: Pancreatic cancer is a highly lethal disease with a poor prognosis while metformin has been associated with a decreased risk of pancreatic cancer. Although the benefit of metformin was observed for pancreatic cancer prevention, it is not clear whether it can also affect the survival of pancreatic cancer patients with type 2 diabetes mellitus. A systematic review and meta-analysis was conducted to assess the effect of metformin on the survival of pancreatic cancer patients with type 2 diabetes mellitus...

Cell proliferation assays are widely applied in biological sciences to understand the effect of drugs over time. However, current methods often assess cell population growth indirectly, that is, the cells are not actually counted. Instead other parameters, for example, the amount of protein, are determined. These methods often also demand phototoxic labels, have low temporal resolution, or employ end-point assays, and frequently are labor intensive. We have developed a robust and label-free kinetic cell proliferation assay with high temporal resolution for adherent cells using digital holographic microscopy (DHM), one of many quantitative phase microscopy techniques...

OBJECTIVE: Sepsis, triggered by microbial infection, is a common and life-threatening systemic illness, often leads to impaired function of vital organs. Ischemic preconditioning induced by transient brief episodes of ischemia is a powerful innate mechanism of organ protection. We have reported that a 15-minute renal ischemic preconditioning substantially attenuated subsequent renal ischemia-reperfusion injury. Here, we investigate whether a brief ischemia and reperfusion in kidney can provide protection at local and remote sites against sepsis-induced organ injury, and whether this protection is microRNA-21 dependent...

Tulsi, also known as holy basil, is indigenous to the Indian continent and highly revered for its medicinal uses within the Ayurvedic and Siddha medical systems. Many in vitro, animal and human studies attest to tulsi having multiple therapeutic actions including adaptogenic, antimicrobial, anti-inflammatory, cardioprotective, and immunomodulatory effects, yet to date there are no systematic reviews of human research on tulsi's clinical efficacy and safety. We conducted a comprehensive literature review of human studies that reported on a clinical outcome after ingestion of tulsi...

STUDY QUESTION: Do regulatory T cells (Tregs) contribute to angiogenesis in endometriosis? SUMMARY ANSWER: High levels of CCL17 and CCL22 cause the recruitment of Tregs, upregulate the immunosuppression of Tregs and, in turn, may promote angiogenesis in endometrial cells in synergy with proinflammatory cytokines. WHAT IS ALREADY KNOWN: The peritoneal fluid of patients with endometriosis has a higher percentage of Tregs than that of normal individuals; however, the regulatory role of Tregs in the disease remains unclear...

Fatemeh Kalalinia, Iman Karimi-Sani
Cancers are usually treated by anticancer agents that are toxic for both normal and cancer cells, so these drugs have major side effects and they are not suitable and enough effective for cancer prevention. Solamargine, a steroidal alkaloid glycoside found in Solanum species such as Solanum nigrum, displayed several therapeutic activities. We aim to review the use of solamargine in experimental cancer studies. Articles published in biology journals between 1975 and 2017 were retrieved from PubMed, Scopus, and Web of Science using relevant keywords...

Introduction: Excessive apoptosis has been hypothesized as possible cause of tendinopathy and tear in the tendons of the rotator cuff (RC). Different mechanisms and molecules play a key role in cell regulation. Biological interventions can affect the process of apoptosis to control the tendinopathy process, and may be useful to design new treatments. Source of data: We identified basic science, in vitro and in vivo preclinical and clinical studies listed in the Pubmed Google Scholar, CINAHL, Cochrane Central and Embase Biomedical databases in English, Spanish, Italian and French concerning the effects of apoptosis on RC tendons...
