The freeing up of employees from repetitive tasks can also help reduce costs related to worker accident and injury.
In the United states as many as 65 percent of all food factory workers had experienced injury while working on the job.
Costs related to worker injury are considerable. In addition to injury pay, they can also have a direct impact on insurance premiums, lost labour and production interruption as well as the distress of a valued team member.
Lightweight robots now have many built-in features to ensure they can work safely side-by-side with factory workers.

High-grade cervical lesions occur most often in women 40 or younger. Because the lesions can progress to cancer,
they are removed today usually by surgery, freezing, or laser treatment. The procedures remove the precancerous areas in about 80 percent of women.
Less troublesome low-grade lesions usually are monitored just. They pose less of a cancer risk and usually regress on their own.
with newly diagnosed, high-grade precancerous cervical lesions. The women were assigned randomly to receive either three doses of the vaccine over a 12-week period or saline injections.
55 (48.2 percent) had regression of their precancerous lesions, meaning they disappeared or converted to low-grade lesions,
compared with 12 of 40 (30 percent) who received saline. The regression rate was closer to 50 percent in 107 women who received all three vaccine doses. n many of these women,
the vaccine not only made their lesions disappear, but it also cleared the virus from their cervix,
Trimble says. n most unvaccinated patients whose lesions went away, the virus was still present,
and many still had low-grade lesions. Clearance of the virus is a ignificant bonus she says,
because lingering HPV is a major risk factor for recurrence of cervical lesions. In biopsy samples, patients whose lesions completely regressed after vaccination had more immune T cells in the tissue. t important that T cells capable of recognizing HPV stay in the cervix
and fight off any recurrence of the infection, Trimble says. She is also studying other types of vaccines to prevent high-grade cervical lesions from developing into cancer.
The injection vaccine is made by Inovio Pharmaceuticals Inc, . which funded the clinical trial and whose employees coauthored the report with Trimble.

The study's lead author, Caitlin Dow, said the findings were particularly important for people who cannot exercise because of injury or physical limitations."
Eventually, the buildup of misfolded proteins can cause lesions to form in the brain, leading to disease."
#Use of Ultrasound to Promote Faster Healing of Wounds Sometimes discoveries in science are not about the development of new medical devices or drugs,
Researchers from University of Sheffield have used now ultrasound to reduce healing times of diabetic wounds by 30%.
%The study, published in the Journal of Investigative Dermatology, describes the use of ultrasonic waves to promote wound healing cells called fibroblasts to migrate into the wound through mechanical stimulation.
and delayed wound healing of diabetic and elderly patients. sing ultrasound wakes up the cells
this technique for accelerated wound healing is expected to be in broad clinical use in the next 3-4 years.
Treatment of diabetic and aged mice recruits fibroblasts to the wound bed and reduces healing times by 30,

Water from the blood is the catalysis that sets it fizzing. f you can get the particles in the general area of the wound,
all the way to the damaged internal blood vessels feeding the wound. By clotting so deep into the lesion, the clot was shown to be more stable.
Right now the fizzing agent is a bit messy. While chemicals do get deeper into the wound,
they pop off in every other direction too. Eventually researchers hope to make the delivery process more efficient,
and cure bones damaged due to tumors, cysts or fractures. The use of bone replacement in various forms has increased in recent years.
For example, the hydrogel can be designed to remain at the injury site for specific durations by controlling the interactions between the nanosilicates and gelatin,
In addition to its ability to be injected at the site of an injury, the material achieves three-to-four times higher stiffness once inside the body,

a novel microtubule-based regulator of wound healing"."e envision that our nanoparticle therapy could be used to speed the healing of all sorts of wounds,
including everyday cuts and burns, surgical incisions, and chronic skin ulcers, which are a particular problem in the elderly
Dr. Sharp and his colleagues had discovered earlier that an enzyme called fidgetin-like 2 (FL2) puts the brakes on skin cells as they migrate towards wounds to heal them.
and applied the nanoparticles to wounds on mice. The treated wounds healed much faster than untreated wounds.
FL2 belongs to the fidgetin family of enzymes, which play varying roles in cellular development and function.
When those cells were placed on a standard wound assay (for measuring properties like cell migration and proliferation),
Dr. Sharp and project co-leader Joshua Nosanchuk, M d.,professor of medicine at Einstein and attending physician, infectious diseases at Montefiore Medical center, developed a wound-healing therapy that uses
In both cases, the wounds closed more than twice as fast as in untreated controls. ot only did the cells move into the wounds faster,

who led the current research. hey found the lesions were very persistent in DNA, meaning we don have a repair system to take them out,
Essigmann says. n our field lesions that are persistent, if they are also mutagenic, are the kind of lesions that would initiate cancer,
he adds. DNA sequencing of a developing gastrointestinal tumor revealed two types of mutation: cytosine (C) bases changing to thymine (T) bases,
the researchers decided to investigate the lesion further, in a bid to uncover if it is indeed mutagenic.
the researchers replicated the genome containing the lesion with a variety of different types of polymerase,
the researchers predict that accumulation of the lesions would increase the mutation rate of a cell up to 30-fold,
