The highly-infectious disease is similar to Ebola, with symptoms including fever, muscle pains, diarrhea, vomiting, and, in some cases, death through extreme blood loss.

Hundreds of people have died from the virus in recent years, almost all in Africa.

According to the World Health Organization (WHO), on average, the Marburg virus kills half of the people it infects, with previous outbreaks killing between 24% and 88% of patients.

The virus was first identified in 1967 after 31 people were infected and seven died in simultaneous outbreaks in Marburg and Frankfurt in Germany and Belgrade in Serbia.

The outbreak was traced to African green monkeys imported from Uganda.

But the virus has since been linked to other animals.

COVID-19: Long-term effects

Most people who get coronavirus disease 2019 (COVID-19) recover within a few weeks. But some people — even those with mild versions of the disease — might have symptoms that last a long time afterward. These ongoing health problems are sometimes called post-COVID-19 syndrome, post-COVID conditions, long COVID-19, long-haul COVID-19, and post-acute sequelae of SARS-COV-2 infection (PASC).

Debye Scherrer equation for calculating the crystallite size is given by = / (1) where K is the Scherrer constant, λ is the wavelength of light used for the diffraction, β the “full width at half maximum” of the sharp peaks, and θ the angle measured. The Scherrer constant (K) in the above formula accounts for the shape of the particle and is generally taken to have the value 0.9. The results revealed that the crystallite size is less than 100 nm. , was developed in 1918, to calculate the nano crystallite size (L) by XRD radiation.cos Scherrer Equation, L K of wavelength λ (nm) from measuring the full width at half maximum of peaks (β) in radian located at any 2θ in the pattern. The shape factor of K can be 0.62 - 2.08 and is usually taken as about 0.89. But, if all of the peaks of a pattern are going to cosθ must be identical. Given a similar value of L, X-ray diffraction is a convenient method for determining the mean size of nanocrystallites in nanocrystalline materials.

It goes without saying that if someone has a blood clot in their brain, it should be cleared as soon as possible. An experimental new transducer could help, as it uses swirling waves of ultrasound to break up blood clots much faster than existing methods.

Developed by scientists at North Carolina State University and the Georgia Institute of Technology, the device is designed specifically for use on what is known as cerebral venous sinus thrombosis (CVST) clots. These form in veins that ordinarily allow blood to drain from the brain. When those veins are blocked, blood pressure in the brain increases, so potentially lethal or disabling bleeding may occur.

Researchers in Australia have demonstrated a specially engineered form of fermentable fiber can lower blood pressure in patients with hypertension. The randomized, placebo-controlled trial revealed just three weeks of dietary supplementation decreased blood pressure in hypertensive patients as effectively as currently used drugs.

Doctors have long suggested dietary changes should be the first option to treat hypertension in patients. The intervention is known as DASH (Dietary Approach to Stop Hypertension), and it has proven to be incredibly effective at lowering blood pressure in many patients.

Francine Marques, from the Monash University School of Biological Sciences, has been investigating the association between these SCFA metabolites and blood pressure for several years. Prior preclinical studies have shown that acetate and butyrate can lower blood pressure in animal models.

"These metabolites have untapped translational potential," explained Marques. "Our previous studies found that acetate and butyrate, two microbial SCFAs, decreased blood pressure in mice. However, this method would require patients to ingest SCFAs 24/7, making it unsuitable for humans."

So Marques and colleagues wondered whether a type of engineered fiber could be deployed to help our gut microbes deliver consistently high levels of beneficial SCFAs. The researchers turned to a fiber known as high-amylose maize starch, which can be modified to incorporate acetate and butyrate. The ultimate product is referred to as HAMSAB (acetylated and butylated high-amylose maize starch).

As our gut microbes ferment HAMSAB, high volumes of acetate and butyrate are released into the colon. The question this clinical trial set out to answer was whether HAMSAB supplementation in patients with hypertension can effectively lower blood pressure.

Respiratory syncytial (sin-SISH-Uhl) virus, or RSV, is a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious, especially for infants and older adults. RSV is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia (infection of the lungs) in children younger than 1 year of age in the United States.

World Down Syndrome Day (WDSD) is marked each year on March 21, beginning in 2006. The 21st day of March (the 3rd month of the year) was selected to signify the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome.

Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby's body forms and functions as it grows during pregnancy and after birth. Typically, a baby is born with 46 chromosomes.

The new version, known as BA.2, is a descendant of the Omicron variant (known as BA.1). According to the WHO, BA.2 has some differences in some of the mutations—including ones on the spike protein—than BA.1. Those differences, along with BA.2's increasing spread in some areas, led the WHO to recommend that "investigations into the characteristics of BA.2, including immune escape properties and virulence, should be prioritized independently (and comparatively) to BA.1."

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of concern has spread rapidly since its emergence in late 2021. Presently, an Omicron subvariant known as BA.2, first identified in late 2021, has made headlines due to its rapid spread.

Omicron mutated into sister sublineage BA.2

While Omicron has approximately 60 mutations, it is thought that its sister lineage may have 85 mutations. The World Health Organization (WHO) stated over the weekend that this lineage differs from the original Omicron strain by several mutations, including those of the spike protein, the SARS-CoV-2 protein that mediates host cell entry. This variant has also been termed the “stealth variant” due to a mutation that renders it ‘invisible’ as Omicron to PCR testing.

Digestive symptoms were common in patients with COVID-19, according to the American Journal of Gastroenterology. Patients with these symptoms had a long time from onset to admission and their prognosis was worse compared with patients without symptoms.

“Clinicians should recognize that digestive symptoms, such as diarrhea, maybe a presenting feature of COVID-19, and that the index of suspicion may need to be raised earlier in at-risk patients presenting with digestive symptoms rather than waiting for respiratory symptoms to emerge,” Lei Pan, MD, Ph.D., from the Department of Respiratory and Critical Care Medicine at Binzhou Medical University Hospital and the Second Medical Center & National Clinical Research Center for Geriatric Diseases at the Chinese PLA General Hospital, and colleagues wrote. “However, further large sample studies are needed to confirm these findings.”

During the month of December, the incidence of diarrhea increased, which is characterized by the rapidity of its symptoms and its persistence for a long time. The Iraqi doctors and scientists attributed that the cause of this type of infection is due to the infection of the Coronavirus in the digestive system of humans and animals, and the symptoms of diarrhea and vomiting appear more than the symptoms related to the respiratory system, which include colds, sneezing and shortness of breath.

Experts: Corona Omicron will overwhelm the entire world within 3 to 6 months

"Our current vaccines will survive to some extent, with this new alternative .. the new variant may reduce the effectiveness of the vaccine by two degrees, but this is not yet clear."

The Corona Omicron variant is still causing panic around the world, despite the confirmation of specialist doctors that the new variant causes mild symptoms, especially with receiving the vaccine against the emerging virus.

Several countries have taken precautionary measures to restrict travel from some African countries, despite the warning of the World Health Organization and the Secretary-General of the United Nations that travel restrictions will not work and will not prevent the new variant from moving and crossing the borders.

The first case of omicron, classified by the World Health Organization as a "worrying" variant, was detected in South Africa.
