A research group has revealed that amyloid-β (Aβ) detected in blood is secreted from peripheral tissues (pancreas, adipose tissue, skeletal muscle, liver, etc.) that are sensitive to glucose and insulin. Also, that Aβ secreted from peripheral tissues acts as a regulator on pancreatic β-cells to suppress insulin secretion. The results of this study indicate that blood Aβ levels fluctuate significantly with diet, and special care should be taken when using blood samples as a diagnostic marker for Alzheimer's disease, such as taking blood samples during fasting.

Scientists develop a method to genetically label neurons with a single gene of interest in mice by combining the anterograde transsynaptic spread of adeno-associated virus serotype 1 (AAV1) with intersectional gene expression. In two distinct circuits: the retina/primary visual cortex to the superior colliculus and the bilateral motor cortex to the dorsal striatum, injections of AAV1 expressing either Cre or Flpo recombinases and the Cre/Flpo double-dependent AAV into two upstream regions and the downstream region, respectively, were used to label postsynaptic neurons receiving inputs from the two upstream regions.

Hong Kong has an aging population. The number of people 65 or older is forecast to increase to 2.16 million by 2031 and 2.56 million by 2041. As a result, Hong Kong’s recurrent social welfare and health expenditure as a percentage of nominal GDP is forecast to increase from $52.4 billion in 2014 to $563.6 billion in 2042. Hong Kong may experience a structural financial deficit within a decade because of higher social and health spending for older adults and a smaller working-age population.

• Your chances of getting resuscitated by a bystander in Asia if your heart suddenly stops while in a public place depends on whether you’re a man or a woman. • Across nine Asian communities, in public locations, the bystander CPR rates were 31.2 per cent for females and 36.4 per cent for males. • For women, the chances of receiving bystander CPR when suffering a cardiac arrest in a public out-of-hospital setting is lower than for men; in homes or private places, the likelihood is reversed.

New research finds the extent of arterial occlusive disease in the popliteal artery correlates with the prognosis of peripheral arterial disease in lower limbs. The study of 31 patients who underwent percutaneous angioplasty of femoropopliteal artery (FPA) proved for the first time that ulcerated plaque observed in the FPA during angioscopy is the source of the thromboembolic mechanism in the popliteal artery.

Garden soil houses a variety of bacteria and their natural byproducts — including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments.

Broccoli may contain advantages beyond nutrition. A molecule found in broccoli, cabbage and more digests down into DIM, a compound with brighter benefits than the name implies, such as inducing cell death in breast, prostate and colon cancer. Now, researchers are beginning to understand the mechanism underpinning this molecular behavior — information that could help elucidate future anti-cancer treatments.

Researchers from Osaka City University have shown in mice models of Alzheimer's disease, frontotemporal dementia, and dementia with Lewy bodies, that the intranasal administration of rifampicin and resveratrol in combination is safer and improves cognitive function more than rifampicin alone. The research results are expected to lead to the development of safe and effective nasal spray for the prevention of dementia.

By searching for the protein transglutaminase 1 (TGM1) among patients with various autoimmune skin diseases, researchers have successfully identified a separate disease that can be linked to autoimmunity against TGM1. This backward method demonstrates a new way of identifying autoantigens as markers for various diseases. By letting autoantigens point to the disease, diagnosis and treatment can be facilitated, according to the study now published in PNAS.
