Good morning @jidesanwoolu, how is your health now Sir? Thank God you are looking well and alive. We are grateful to God.

We want to bring to your remembrance the End SARS terrorist attack in Lagos on October 20, 2020. A lot are not satisfied with the responses from Lagos State.

During a normal pregnancy, oxidative stress enhances antioxidant mechanisms that are capable of reacting by way of enzyme activity and non-enzyme free radical deactivators. However, pregnancy is also a state in which this adaptation and balance may be easily disrupted.

There is strong evidence that a chronicin flammatory reaction combined with the presence of a local oxidizing environment may play a vital role in the etiology and development of complications during pregnancy.

In late pregnancy, damage to DNA (especially when it is caused by oxidative stress) is associated with pre-eclampsia(PE), intrauterine growth restriction (IUGR), and the death of mothers in developing countries; it largely determines pregnancy – related susceptibility to diseases

The referential values of ROS and NOS and their minimal and safe concentrations or physiologically beneficial concentrations are yet to be determined.

The measurement of oxidative stress in vivo is perceived as controversial,

as the sen-sitivity and specificity of various oxidative stress markers is unknown.. .

1/23 We haven't had a lot to celebrate during this pandemic. But achieving the milestone of offering vaccine to the over 70s, health and care workers and the most clinically vulnerable just before target date is a huge cause for celebration, given the scale of the achievement.

2/23 When Margaret Keenan got her first jab in Coventry on December 8th last year, who’d have thought that, by Valentine’s Day, we’d have vaccinated over fourteen million people across the UK in just ten short weeks? Amazing, extraordinary and truly, really, world class!

3/23 I’ve been struck by how much joy and relief has been brought to those doing the vaccinations and those receiving them. A GP told me yesterday that nothing had given him greater pleasure in his long career. And that the patient's relief was sometimes overwhelming.

4/23 It's vital to recognise the extraordinary contribution of the staff and volunteers who have made this happen. One of my close family had their jab yesterday and was in awe of the volunteer standing outside in the freezing cold for a four hour shift meeting and greeting.

5/23 What I wanted to share in this thread was the slightly untold story of some of the extraordinary challenges the NHS has had to overcome to deliver this target. Requiring superhuman effort from NHS leaders and staff, way beyond the call of duty. Five challenges set out below.

Here is a tweetorial from our latest publication in @Annals_Oncology about longitudinal tracking of esophageal adenocarcinoma. #OesophagealCancer #EsophagealCancer https://t.co/QWvrzBXmK7 1/8

We sequenced 245 plasma samples from 97 patients with oesophageal adenocarcinoma using a 77 gene pan-cancer ctDNA panel. 2/8

Variants derived from previously characterised driver oesophageal adenocarcinoma genes had a significantly higher VAF than variants from other genes, indicating selection. 3/8

Peripheral blood cell samples were also sequenced for 78/97 patients. CHIP mutations were identified in 23% of cases, longitudinal tracking of CHIP variants suggested these variants were dynamic over time. 4/8

We found patients that were ctDNA positive post-surgery had a significantly poorer survival than ctDNA negative patients, and the elimination of CHIP variants improved the positive predictive value. 5/8
