4-(Nitrophenylsulfonyl)piperazines mitigate radiation damage to multiple tissues.

2017

PloS one

Micewicz ED, Kim K, Iwamoto KS, Ratikan JA, Cheng G +13 more

Plain English
Researchers studied a group of new compounds that can help reduce damage caused by radiation exposure, especially in cases like radiation sickness or injury from cancer treatments. They found that one key compound significantly lowered death rates in mice exposed to harmful radiation, showing a 50% reduction in mortality from radiation-related conditions. This discovery is important because it could lead to better treatments for people who accidentally encounter radiation or need radiation therapy for cancer. Who this helps: This benefits patients undergoing radiation therapy and those at risk of accidental radiation exposure.

Extensive seed and pollen dispersal and assortative mating in the rain forest tree Entandrophragma cylindricum (Meliaceae) inferred from indirect and direct analyses.

2017

Molecular ecology

Monthe FK, Hardy OJ, Doucet JL, Loo J, Duminil J

Plain English
This study looked at how pollen and seeds move and mix in a valuable rainforest tree species called Entandrophragma cylindricum in East Cameroon. Researchers found that most pollen comes from different trees, with about 4.76 different trees contributing to each seed. However, seeds within the same fruit often come from the same father tree. The seeds and pollen can travel up to 600 meters, and they also found that 40% of pollen and seeds come from outside the study area, showing a strong exchange with surrounding trees. Who this helps: This information benefits conservationists and forest managers who work to sustainably manage timber resources.

An Aptamer Bio-barCode (ABC) assay using SPR, RNase H, and probes with RNA and gold-nanorods for anti-cancer drug screening.

2017

The Analyst

Loo J, Yang C, Tsang HL, Lau PM, Yong KT +2 more

Plain English
This study focused on improving a test called the ABC assay to detect a protein, cytochrome-c, which indicates cancer cell death. Researchers found that this new test could accurately detect cytochrome-c at very low levels—1 nanomole for the aptamer and 80 picomoles for cytochrome-c—and could be completed in three hours without requiring complex steps. This matters because it offers a quick and reliable way to screen for new anti-cancer drugs, which is vital for developing effective treatments. Who this helps: Patients with cancer, particularly those with drug-resistant types.

Authentication of Smartphone Users Based on Activity Recognition and Mobile Sensing.

2017

Sensors (Basel, Switzerland)

Ehatisham-Ul-Haq M, Azam MA, Loo J, Shuang K, Islam S +2 more

Plain English
This study looked at how to better protect sensitive information on smartphones by using the device's sensors to recognize user behavior instead of relying solely on passwords or fingerprints. Researchers created a new authentication system that analyzes data from sensors like the accelerometer and gyroscope, and found it to be effective in distinguishing between different users. This is important because it makes smartphones more secure against theft or loss, where traditional methods could fail. Who this helps: This helps smartphone users, especially those with sensitive personal data.

Spatially explicit multi-threat assessment of food tree species in Burkina Faso: A fine-scale approach.

2017

PloS one

Gaisberger H, Kindt R, Loo J, Schmidt M, Bognounou F +16 more

Plain English
This study looked at 16 important food tree species in Burkina Faso, like the Baobab and Shea tree, to understand how various threats—such as climate change, overgrazing, and cotton production—affect them. The researchers found that all these tree species are at risk, with climate change being the biggest long-term threat and overexploitation the major short-term issue. This matters because these trees are vital for local income and nutrition, and protecting them is essential for the wellbeing of rural communities. Who this helps: This benefits local farmers and communities who rely on these trees for food and income.

Direct engagement of the PI3K pathway by mutant KIT dominates oncogenic signaling in gastrointestinal stromal tumor.

2017

Proceedings of the National Academy of Sciences of the United States of America

Bosbach B, Rossi F, Yozgat Y, Loo J, Zhang JQ +9 more

Plain English
Researchers studied gastrointestinal stromal tumors (GISTs), which often have mutations in the KIT gene. They found that when a key signaling pathway (PI3K) was disrupted in mice, the development of these tumors stopped completely, even though the normal cells that can turn into GISTs remained healthy. Additionally, using drugs that block the PI3K pathway led to a reduction in tumor growth, making this approach promising for treating tumors that do not respond to standard therapies. Who this helps: This research benefits patients with gastrointestinal stromal tumors, especially those whose cancers resist existing treatments.

Differential expression of long non-coding RNAs in patients with tuberculosis infection.

Tuberculosis (Edinburgh, Scotland)

He J, Ou Q, Liu C, Shi L, Zhao C +5 more

Plain English
This study looked at long non-coding RNAs (lncRNAs) in the blood of tuberculosis (TB) patients, healthy people, and those with pneumonia. Researchers found 2,116 lncRNAs that were expressed differently in TB patients, with 1,102 of them being higher and 1,014 lower compared to others. These findings show that specific lncRNAs could serve as quick indicators for diagnosing TB, which is crucial for controlling its spread. Who this helps: This helps patients at risk of TB and healthcare providers who need faster diagnostic tools.

Identification of unique neoantigen qualities in long-term survivors of pancreatic cancer.

2017

Nature

Balachandran VP, Łuksza M, Zhao JN, Makarov V, Moral JA +54 more

Plain English
This study examined the characteristics of certain tumor markers, called neoantigens, in patients with pancreatic cancer who survive longer than five years. Researchers found that these long-term survivors had tumors with a high number of specific neoantigens and strong immune cell activity, which were better at activating immune responses compared to those with just more neoantigens. This is important because identifying these neoantigen qualities could lead to improved immunotherapy treatments for pancreatic cancer patients. Who this helps: This helps patients with pancreatic cancer and their doctors by providing insights for better treatment options.

Plain English
This study looked at a new way to create and package tiny devices that analyze cells, called microfluidic flow cytometers. Researchers tested two special adhesives and found that one of them, DXL-009, performed better because it allowed for clearer detection of cells. This method also made it easier to produce these devices in bulk without needing extra glue layers, which can save time and reduce costs. Who this helps: This advancement benefits researchers and manufacturers of medical diagnostic devices.
