Low Levels Of “Memory Protein” Linked to Cognitive Decline in Alzheimer’s Disease

Working with human brain tissue samples and genetically engineered mice, Johns Hopkins Medicine researchers together with colleagues at the National Institutes of Health, the University of California San Diego Shiley-Marcos Alzheimer's Disease Research Center, Columbia University, and the Institute for Basic Research in Staten Island say that consequences of low levels of the protein NPTX2 in the brains of people with Alzheimer’s disease (AD) may change the pattern of neural activity in ways that lead to the learning and memory loss that are hallmarks of the disease.

When Hollywood Met Neurosurgery

A team of computer engineers and neurosurgeons, with an assist from Hollywood special effects experts, reports successful early tests of a novel, lifelike 3D simulator designed to teach surgeons to perform a delicate, minimally invasive brain operation.

Six Johns Hopkins Doctors Elected to Association of American Physicians

Six Johns Hopkins physicians were elected to the Association of American Physicians at the annual meeting of the organization April 21-23 in Chicago.
 

Physicians Vastly Underestimate Patients’ Willingness to Share Sexual Orientation, Study Finds

A study that surveyed a national sample of emergency department health care providers and adult patients suggests that patients are substantially more willing to disclose their sexual orientation than health care workers believe.

Discovering the Basics of “Active Touch”

Working with genetically engineered mice — and especially their whiskers — Johns Hopkins researchers report they have identified a group of nerve cells in the skin responsible for what they call “active touch,” a combination of  motion and sensory feeling needed to navigate the external world. The discovery of this basic sensory mechanism, described online April 20 in the journal Neuron, advances the search for better “smart” prosthetics for people, ones that provide more natural sensory feedback to the brain during use.

Johns Hopkins Center for Inherited Disease Research Receives $213 Million of New Funding

The Johns Hopkins Center for Inherited Disease Research (CIDR) marked its 20-year history supporting large-scale scientific collaboration by securing funding to the center through 2023.  CIDR successfully competed for a seven-year contract from the National Institutes of Health (NIH) providing up to $213 million in research funding. The renewal contract enables NIH-funded researchers to use CIDR’s sequencing, high-throughput genotyping, analysis and informatics services for a wide array of studies exploring genetic contributions to human health and disease.

New Evidence: Defective HIV Proviruses Hinder Immune System Response and Cure

Researchers at Johns Hopkins and George Washington universities report new evidence that proteins created by defective forms of HIV long previously believed to be harmless actually interact with our immune systems and are actively monitored by a specific type of immune cell, called cytotoxic T cells.

Noninvasive Imaging Test Shown Accurate in Ruling out Kidney Cancers

The latest in a series of studies led by researchers at Johns Hopkins Medicine shows that addition of a widely available, noninvasive imaging test called 99mTc-sestamibi SPECT/CT to CT or MRI increases the accuracy of kidney tumor classification. The research team reports that the potential improvement in diagnostic accuracy will spare thousands of patients each year in the United States alone from having to undergo unnecessary surgery.

Hopkins Researchers Discover Birth-And-Death Life Cycle of Neurons in the Adult Mouse Gut

Johns Hopkins researchers today published new evidence refuting the long-held scientific belief that the gut nerve cells we’re born with are the same ones we die with.

Air Pollution May Directly Cause Those Year-Round Runny Noses, According to a Mouse Study

Although human population studies have linked air pollution to chronic inflammation of nasal and sinus tissues, direct biological and molecular evidence for cause and effect has been scant. Now, Johns Hopkins researchers report that experiments in mice continually exposed to dirty air have revealed that direct biological effect.

For Keeping X Chromosomes Active, Chromosome 19 Marks The Spot

After nearly 40 years of searching, Johns Hopkins researchers report they have identified a part of the human genome that appears to block an RNA responsible for keeping only a single X chromosome active when new female embryos are formed, effectively allowing for the generally lethal activation of more than one X chromosome during development. Because so-called X-inactivation is essential for normal female embryo development in humans and other mammals, and two activated X chromosomes create an inherently fatal condition, the research may help explain the worldwide human sex ratio that has slightly favored males over females for as long as science has been able to measure it. The results appear online in the April 12 issue of the journal PLOS ONE.

11 Johns Hopkins Nurses Receive 2017 Excellence in Nursing Award from Baltimore Magazine

Baltimore magazine is honoring 11 Johns Hopkins nurses and nurse leaders for their extraordinary contributions to health care in its third annual “Excellence in Nursing” issue this May.

Paul Rothman and Arturo Casadevall Elected to the American Academy of Arts and Sciences

The American Academy of Arts and Sciences today announced the election of 228 new members, including Paul B. Rothman, M.D. and Arturo Casadevall, M.D., of The Johns Hopkins University. 

Media Advisory: Maryland’s Top Cancer Scientists Discuss Research on Tracking and Treating Cancer

At the annual “Research Matters” conference on Wednesday, April 12, scientists at Maryland’s two academic cancer centers will meet to discuss how scientists are using advanced imaging methods to develop better ways pinpoint and track cancer cells — down to the microscopic level — and precisely target each cell with anti-cancer drugs.

Johns Hopkins Researchers Win Top Prizes, Honors at Cancer Research Meeting

Johns Hopkins Kimmel Cancer Center researchers received the following honors and awards at the 2017 annual meeting of the American Association for Cancer Research, April 1-5 in Washington, D.C.

Quickly Assessing Brain Bleeding in Head Injuries Using New Device

In a clinical trial conducted among adults in 11 hospitals, researchers have shown that a hand-held EEG device approved in 2016 by the U.S. Food and Drug Administration that is commercially available can quickly and with 97 percent accuracy rule out whether a person with a head injury likely has brain bleeding and needs further evaluation and treatment.

Probiotics Benefit in Schizophrenia Shaped by Yeast Infections

In a small pilot study of men with schizophrenia, researchers at Johns Hopkins Medicine and Sheppard Pratt Health System say they have evidence that adding probiotics — microorganisms, such as bacteria found in yogurts — to the patients’ diets may help treat yeast infections and ease bowel problems. Probiotics may also decrease delusions and hallucinations, but in the study, these psychiatric benefits mostly affected those without a history of yeast infections.

Tip Sheet: Immunotherapy Trials, Prostate Cancer Biology among Research Findings to Be Presented By Johns Hopkins Scientists

See below for brief descriptions of research scheduled for presentation by Johns Hopkins Kimmel Cancer Center and Bloomberg~Kimmel Institute for Cancer Immunotherapy scientists at the 2017 Annual Meeting of the American Association for Cancer Research, April 1 – 5 in Washington, D.C.

Distracted Driving Awareness Events to Educate People about the Dangers of Losing Attention behind the Wheel
