Marine Sponges

Leucettazoles As Cryptic Macro cyclic Alkaloid Dimers From a Marine Sponge

Marine sponges are a remarkable source of structurally diverse natural products. For example, over several decades, our investigation of southern Australian marine sponges revealed a wealth of natural product classes, many unique to marine sponges. These include the terphenyls luffarins and trunculins, the alkaloids trachycladindoles and dragmacidins, the polyketides franklinolides and amphilactams; the lipids heterofibrins and thiocyanate; and…

Mosquito

Insecticide Resistance Genes Affect West Nile Virus

In a context of overuse of insecticides, which leads to the selection of resistant mosquitoes; it is already known that this resistance to insecticides affects interactions between mosquitoes and the pathogens they transmit. Researchers from the Institut Pasteur (Paris) and its partners prove that mechanisms of insecticide resistance; observed in Culex quinquefasciatus vector, impact the transmission of…

Diabetes

Functional Insulin-producing Cells: Grown In Lab

UC San Francisco researchers have for the first time transformed human stem cells into mature insulin-producing cells; a major breakthrough in the effort to develop a cure for type 1 (T1) diabetes. Replacing these cells, which are lost in patients with T1 diabetes; has long been a dream of regenerative medicine; but until now scientists had…

Expanding Pill Could Be Used To Monitor Stomach Conditions

The soft, squishy device, which is made from hydrogel materials, is softer, longer lasting and more biocompatible than some of the current ingestible stomach sensors that can only stay in the stomach for a few days. Lin and colleagues wanted to design a hydrogel-based pill that could be used to carry sensors into the stomach to…

How Pancreatic Cancers Start: New 3-D Imaging Technique Reveals

A new technique to study tissue samples in 3-D has revealed that pancreatic cancers can start and grow in two distinct ways, solving a decades-old mystery of how tumours form. The new method could help researchers to get more information from tissue biopsies; and may lead to improved treatments for pancreatic cancers. The technique was developed…

Microscopic Eye Movements Affect How We See Contrast

It is often difficult for a driver to see a person walking on the side of the road at night especially if the person is wearing dark colors. One of the factors causing this difficulty is a decrease, in contrast, making it hard to segment an object; such as a person, from its background. Researchers…

Wrist Bones

Wrist Bones Revealed By MRI And Computer Modeling

The researcher uses our wrists constantly, but how do they work? In a just-published Journal of Biomechanics article; the researchers proved a longtime assumption about individuals’ right and left wrists; while also finding differences between wrists of males and females: discoveries that could help inform and guide future treatments. “If someone has dysfunction of the wrist, it…

Kidney transplantation

Made-to-order Human Kidneys, One Step Closer

The chronic global shortage of donor kidneys leaves many end-stage renal disease patients reliant on continued dialysis treatment. To address the donor kidney shortage, a team led by researchers at the National Institute for Physiological Sciences in Japan attempted to grow mouse kidneys inside rats using transplanted stem cells. The resulting kidneys appeared to be…

Thrombectomy

Late-Stroke Thrombectomy Benefits All Subgroups

Endovascular therapy is not held due to old age, mild symptoms; or late presentation in patients with large-vessel strokes; and salvageable tissue on perfusion imaging, subgroup analysis of the DEFUSE 3 trial suggests. The DEFUSE 3 randomized trial, presented last year at the International Stroke Conference (ISC) 2018; and published in the New England Journal of Medicineat that time;…

Anesthesia

LESS ANESTHESIA DOESN’T STAVE OFF POST-SURGERY DELIRIUM

In the group that had close brain monitoring, however, there were fewer deaths in the first 30 days after surgery. That was an unexpected finding, and the researchers believe it points to potential benefits linked to close brain monitoring and should be examined in future studies. Many older adults who have major surgery experience postoperative…

Novel Technique Accurately Assesses Cardiovascular Risks

A new noninvasive technique for imaging the carotid artery offers advantages over other imaging methods and could provide an earlier, more accurate assessment of cardiovascular disease risk, according to a study published in the journal Radiology. The carotid arteries are the blood vessels located on the left and right side of the neck that bring oxygenated blood to the head. Plaque…
