Researchers develop new material to replace extracted human teeth for dental research

Extracted human teeth have long been used in conducting dental research, such as evaluating dental ceramic materials as a crown restoration on tooth. It is an inexpensive and straightforward process that simulates clinical situations. However, the collection and use of extracted human teeth is becoming increasingly difficult given the concerns about COVID-19, size-standardization issues, and also time constraints. All these factors have prompted a need for dentine analog materials that could potentially substitute extracted human teeth in laboratory-based mechanical and fatigue tests.

New method for image reconstruction in electrical impedance tomography

Recently, a team led by Prof. DU Jiangfeng from the Key Laboratory of Microscale Magnetic Resonance of Chinese Academy of Sciences (CAS) developed a new method for deep electrical impedance tomography reconstruction without training, which paved a new way for applying electrical impedance tomography technology in determining lesion tissue specificity. This work was published in IEEE Transactions on Pattern Analysis and Machine Intelligence.

Study shows effectiveness of cannabis on mental illness may depend on severity of symptoms

A small team of mental health care researchers from St. Joseph’s Healthcare Hamilton and McMaster University, both in Canada, has found evidence that suggests the effectiveness of cannabis for treating mental illnesses such as depression and insomnia may depend on the severity of symptoms. In their study, published in the journal Comprehensive Psychiatry, the group analyzed data from a group of Strainprint mobile app users.

Examining the impact of cultural myths on pain management in Black people

To honor Black History Month in 2023, I decided to spend some time familiarizing myself with the negative impact of cultural myths about Black people on the health care support our systems provide to Black people. I wanted to consider how the medical system treats Black people and white people as groups and how that might be related to cultural myths. To make sure I based my thinking on well-established evidence, I restricted my study to published, peer-reviewed medical or scientific high-impact journals.

Studies reveal biosafety effects of moderate and high static magnetic fields

In three recent studies, Chinese researchers have delayed natural aging in healthy mice by continuous exposure to quasi-homogeneous static magnetic fields (SMFs) of moderate intensity, mitigated kidney damage induced by the chemotherapeutic drug cisplatin in mice, and investigated the harmful effects of high-gradient SMF exposure on mice with severe type 1 diabetes. Two studies have been published in the journal Antioxidants and one in Zoological Research.
