Scientists have developed a device that can monitor blood flow and help quickly diagnose and treat strokes.
A stroke, one of the leading causes of death worldwide, occurs due to poor blood flow to the brain — a condition known as cerebral ischemia.
Its diagnosis must be done within the first few hours for treatment to be effective, researchers said.
The hybrid device, developed by researchers at the China Academy of Engineering Physics and Army Medical University in China, relies on a combination of to light measuring techniques which could diagnose cerebral ischemia non-invasively and faster than the techniques used currently.
“We can measure blood volume, blood oxygenation and blood flow using suitable near-infrared techniques,” said Liguo Zhu, from China Academy of Engineering Physics.
Zhu said that “near-infrared light penetrates one to three centimetres and allows researchers to probe under the skin.”
The working of the instrument relies on the combination of the near-infrared diffuse optical spectroscopy, which analyses the light scattered from the tissues to calculate the amount of oxygen and blood within an area, and the diffuse correlation spectroscopy, which analyses fluctuation in the tissue-scattered lights to measure blood flow.
“Both techniques share the same detectors, which decreases the number of detectors compared to other instruments,” said Zhu.
“The team’s device can record a comprehensive profile of a body part’s hemodynamics, or blood circulation. Devices should measure as many ‘hemodynamic parameters’ as necessary to obtain an accurate diagnosis, as ‘the hemodynamics of stroke is complex’,” said Hua Feng, from Army Medical University.
Another advantage of the device is that it is cheap and compact, which would make more accessible to the people, and hence, help treatment, diagnosis and chances of stroke, researchers said.
Fujifilm GFX 100 Medium-Format Mirrorless Camera With 100-Megapixel Sensor Launched
Earlier this May, Fujifilm finally took the wraps off its flagship medium-format camera, the GFX 100 and now, the company has officially launched it in India. The GFX 100 is a medium-format, mirrorless camera which boasts of a 100-megapixel sensor, in-body image stabilisation, 4K video recording and phase detection autofocus (PDAF). The camera is available in India at a price of Rs. 7,86,999.
The GFX 100 uses a full-sized body, which means you get a side and bottom hand grips, similar to Canon’s EOS-1DX II. This chunky camera body is quite a handful too, weighing in at roughly 1.36kg. You get a secondary shutter button and dial on the bottom right corner, for when you switch shooting orientations. The controls at the back look very similar to those on the Fujifilm X-T3 as there’s a similar, dual-hinged 3.2-inch touchscreen with a 2.36 million dot resolution. There’s a removable OLED EVF, with a crazy high 5.76-million dot resolution, similar to the Panasonic S1 and S1R. The Fujifilm GFX 100 body is also dust and weather resistant and is built using a magnesium alloy. The dials for shutter speed and ISO have been swapped for a LCD display, which shows you the appropriate dials based on the shooting mode you’re in.
The Fujifilm GFX 100 boasts of a brand-new 102-megapixel BSI CMOS sensor and is powered by Fujifilm’s X-Processor 4 image processor. According to the company, this is the world’s first medium format camera to pack in this kind of sensor size, while still having PDAF and 5-axis in-body stabilisation. 4K video shooting is also supported, up to 30fps, or you can output 10-bit 4:2:2 uncompressed footage over HDMI. Other features include an ISO range of 100-12,800, support for 16-bit RAW files, a Type-C USB port, and two SD card slots with support for up to UHS-II speeds.
At the event, Fujifilm also unveiled the new Premista series of zoom lenses. The lenses are designed for large format sensors, such as the GFX 100, and are aimed for use in professional video productions. The Premista 28-100mm T2.9 will be available in August at a price of $38,800 (roughy Rs. 26,58,537), while the Premista 80-250mm T2.9-3.5 will be available later this year for $39,800 (roughly Rs. 27,27,056).
“With the launch of GFX100, we have achieved a great milestone in our digital camera business,” said Haruto Iwata, Managing Director, Fujifilm India, in a statement. “I am optimistic that the launch will further enhance our presence in India and we will continue introducing cameras that deliver an unparalleled standard of optical brilliance that is sure to delight a photographer’s fantasy.”
Samsung Galaxy Watch Active 2 Will Come With an ECG Monitor: Report
Samsung Galaxy Watch Active 2, which is the company’s unannounced successor to the Galaxy Watch Active, will indeed be launching with an electrocardiogram (ECG) monitor feature for heart rate tracking, if an online report is to be believed. According to leaks and rumours, the upcoming Galaxy Watch Active 2 is expected to be announced next month alongside the Galaxy Note 10 smartphones. Additionally, it is being reported the new ECG feature won’t be functional right away, and it will be enabled through a software update next year.
According to a report by Wareable, the Galaxy Watch Active 2 codenamed “Renaissance” will be launching in three variants — an LTE model, a Bluetooth-only model, and an Under Armour-branded Bluetooth version. All models of the watch will be compatible with both Android and iOS, though the LTE functionality will only work with Android phones at launch. Sizes on offer will be 40mm and 44mm, which is the exact same sizing used on the Apple Watch Series 4.
Regarding the ECG reader, the report confirms that the upcoming Galaxy Watch Active 2 will indeed have it, but as Samsung is still waiting on the FDA approval, the feature won’t be available until sometime in the first half of 2020. There will be some heart rate features that the South Korean tech giant might reveal on stage, but the ECG monitor heart tracking will only work after a software update is rolled out next year.
A few days ago, the Galaxy Watch Active 2 was leaked in all its glory. Additionally, the August 5 date on the leaked watch face suggests that the new watch could be unveiled by Samsung two days before the launch of the Galaxy Note 10 smartphones. Guess, we’ll find out next month.
I have never holidayed alone: Adah Sharma
Actress Adah Sharma who is playing the leading lady in the new web series “The Holiday”, says that she has never been on a solo trip because, for her, more than an exotic location, companionship is what matters when it comes to long-distance travel.
“I have never been on a solo trip. I guess that has happened because I started working at a very young age. I went to Goa along with my best friends from school after the board exam. Since then, I have been to numerous places but always travelled with friends,” Adah told IANS, when asked about her most memorable solo trip.
Recalling her first holiday, she said: “I have a vivid memory of a family trip to Hawaii. We had a stopover at Singapore and we went to a nature park. I was three-years-old then and in the park there were so many birds that I was happy to see!”
In the web series ‘The Holiday’, Adah essays a girl named Mehek, who is getting married. Before her big day, she has a a bachelorette party with three of her male childhood buddies. “The Holiday” also features Priyank Sharma and Ashim Gulati and the show is streaming on Zoom Studios’ YouTube channel.
Sharing how she found the concept different, the actress said: “Usually even in films, we get to see a either group of boys or a group of girls on a road trip. We have had films such as ‘Zindagi Naa Milegi Dobara’ and ‘Veere Di Wedding’. But we don’t get to watch a story where boys and girls are just friends and chilling (together on a vacation).”
So, what is her favourite holiday destination?
“I do not have a favourite holiday destination because more than an exotic place, people around matter the most. At times, even a small place like Lonavala becomes fun if I am with my best friends. It is people who make my life, my trips, and my journey more interesting than exotic locations.” said Adah.
