Guard spokesman Joe Trovato said Monday that about troops have withdrawn from Kenosha after spending a week there in anticipation of demonstrations.

Officer Rusten Sheskey's decision to shoot Jacob Blake in the back during a domestic dispute in August sparked chaotic protests in Kenosha that went on for several nights.

Cries of desperation on Mexico's southern border. This is the town of Tapachula, where migrants who have crossed over from Guatemala are demanding humanitarian visas.

Mexico's national guard is deployed in full riot gear. Guatemala and Honduras have now announced they're deploying their own troops, after news surfaced that new caravans of migrants are forming in Central America with the eventual goal of reaching the United States.

In recent years many migrants have chosen to form up in massive caravans instead of trekking alone, because staying in a group helps protect them from criminals who would prey on them.

Luis Rey Garcia Villagran works for the migrant support center in the town. People are literally drowning. The problems with injustice, the problems with insecurity continue as well as problems with organized gangs who capture and kill people who are over there.

It would have cut off most access to migrants who reach the border, and broadly deny some types of asylum claims including domestic abuse and gang violence.

Far-right social media users have discussed actions tied to January 20 for months, but the storming of the US Capitol "energised" the online chatter, said Jonathan Greenblatt, CEO of the Anti-Defamation League.

The University of Chicago expressed sadness over the death of Yiran Fan, a year-old Ph. Fan was studying at the University of Chicago via a joint program of the Booth School of Business and the Kenneth C.

Griffin Department of Economics. In his first sermon since winning his Senate race on Tuesday, Rev. Raphael Warnock told worshipers at the historic Ebenezer Baptist Church in Atlanta that he wanted to talk to them about "God's victory over violence.

That applies to individuals, that applies to institutions, that applies to nations. You can never get better until you have an actual diagnosis.

A violent mob incited by the president's own words chanted for Mike Pence's lynching at the U. Capitol and Trump made no effort to reach out to his vice president.

Indian airlines started delivering batches of COVID vaccines nationwide on Tuesday, preparing for the launch of a campaign to offer shots to 1.

Vaccinations are set to begin on Saturday in an effort that authorities hope will see million high-risk people inoculated over the next six to eight months.

Airlines were due to deliver 5. Sarah Jeong, the New York Times reporter who made headlines in for antagonizing white people, has branded conservative journalist Andy Ngo "dangerous" and called for his censorship on Twitter.

In a tweet posted on Jan. Patric Ferguson, 29, was taken into custody on charges of kidnapping and killing year-old Robert Howard after forcing him in the backseat of a squad car, police said.

Two newly-elected Black Republican congressmen signed up in support of the attempted Trump coup and overturn the presidential election — now it is time for them to resign.

The two House members are Rep. A decade after the discovery of RNAi mechanism in , the pharmaceutical sector heavily invested in the research and development of siRNA therapy.

There are several advantages that this therapy has over small molecules and antibodies. It can be administered quarterly or every six months. Another advantage is that, unlike small molecule and monoclonal antibodies that need to recognize specific conformation of a protein, siRNA functions by Watson-Crick basepairing with mRNA.

Therefore, any target molecule that needs to be treated with high affinity and specificity can be selected if the right nucleotide sequence is available.

And that the immune system often mistakes the RNAi therapies as remnants of infectious agents, which can trigger an immune response.

However, there were a few companies that continued with the development of RNAi therapy for humans. Alnylam Pharmaceuticals , Sirna Therapeutics and Dicerna Pharmaceuticals are few of the companies still working on bringing RNAi therapies to market.

It was learned that almost all siRNA therapies administered in the bloodstream accumulated up in the liver. That is why most of the early drug targets were diseases that affected the liver.

Repeated developmental work also shed light on improving the chemical composition of the RNA molecule to reduce the immune response, subsequently causing little to no side effects.

In , Alnylam pharmaceuticals became the first company to have a siRNA therapy approved by the FDA. Onpattro patisiran was approved for the treatment of polynueropathy of hereditary transthyretin-mediated hATTR amyloidosis in adults.

It affects 50, people worldwide. To deliver the drug directly to the liver, siRNA is encased in a lipid nanoparticle. The siRNA molecule halts the production of amyloid proteins by interfering with the RNA production of abnormal TTR proteins.

This prevents the accumulation of these proteins in different organs of the body and helps the patients manage this disease.

Other treatment options for hATTR is an orthotopic liver transplant OLT that could potentially help if the disease is still in the early stage.

However, OLT can only slow the progression of the disease and not treat it. There are also small molecule medications that provide temporary relief.

Before Onpattro was released, the treatment options for hATTR were limited. After the approval of Onpattro, FDA awarded Alnylam with the Breakthrough Therapy Designation, which is given to drugs that are intended to treat a serious condition and are a substantial improvement over any available therapy.

It was also awarded Orphan Drug Designations given to those treatments that are intended to safely treat conditions affecting less than , people.

In , FDA approved the second RNAi therapy, Givlaari givosiran used to treat acute hepatic porphyria AHP. The disease is caused due to the accumulation of toxic porphobilinogen PBG molecules which are formed during the production of heme.

These molecules accumulate in different organs and this can lead to the symptoms or attacks of AHP. Givlaari is an siRNA drug that downregulates the expression of aminolevulinic acid synthase 1 ALAS1 , a liver enzyme involved in an early step in heme production.

The downregulation of ALAS1 lowers the levels of neurotoxic intermediates that cause AHP symptoms. Years of research has led to a greater understanding of siRNA therapies beyond those affecting the liver.

As of , ONPATTRO and GIVLAARI, are available for commercial application, and two siRNAs, lumasiran ALN-GO1 and inclisiran, have been submitted for new drug application to the FDA.

Several siRNAs are undergoing phase 3 clinical studies, and more candidates are in the early developmental stage. Other companies that have had success in developing a pipeline of siRNA therapies are Dicerna Pharmaceuticals, partnered with Eli Lily and Arrowhead Pharmaceuticals partnered with Johnson and Johnson.

Several other big pharmaceutical companies such as Amgen and AstraZeneca have also invested heavily in siRNA therapies as they see the potential success of this area of biological drugs.
