June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. A Little About The History!
1628 English physician William Harvey discovers the
circulation of blood. He was the first known to describe
completely and in detail the systemic circulation and
properties of blood being pumped to the brain and body
by the heart.
1665 The first recorded successful blood transfusion
occurs in England: Physician Richard Lower.( dogs)
1667 successful transfusions from lambs to humans
1795 the first human blood transfusion
1818 first successful transfusion of human blood to a
patient for the treatment of postpartum hemorrhage
1900 Karl Landsteiner, an Austrian physician, discovers
the first three human blood groups, A, B, and C. Blood
type C was later changed to O.
4. The major changes in blood transfusion practice
over the last 100 years have largely occurred based
on the experience of military physicians during the
major conflicts of the 20th century. The first use of
preserved blood for transfusion was carried in 1917
in United States
Transfusion methods altered dramatically around the
time of the Vietnam War in the 1970s, when practice
changed from using whole blood to component
therapy.
5. Human Blood Group Systems
The term human blood group systems is defined by International
Society of Blood Transfusion as systems in the human species
where cell-surface antigens—in particular, those on blood cells—are
"controlled at a single gene locus or by two or more very closely
linked homologous genes with little or no observable recombination
between them",[1]
It includes the common ABO and Rh- (Rhesus) antigen systems, as
well as many others; thirty-five major human systems are identified
as of November 2014.[2]
ABO blood groups were discovered by Landsteiner in 1901 Later on
Rhesus blood groups were discovered by Landsteiner and Wiener in
1940. [3]

6. ABO blood group system
divided into four blood types on the basis of
presence or absence of A and B surface antigens.
The blood groups are A, B, O and AB.
The frequency of four main ABO blood groups varies
in the population throughout the world.
ABO blood group system derives its importance from
the fact that A and B are strongly antigenic and anti A
and anti B naturally occurring antibodies present in
the serum of persons lacking the corresponding
antigen, and these antibodies are capable of
producing intravascular hemolysis in case of
incompatible transfusion
Zaman et al. Study of ABO and Rh-D blood group among the common people of Chittagong city corporation
area of Bangladesh. Journal of Public Health and Epidemiology Vol. 7(9), pp. 305-310, September 2015
7. Rh blood group system
It is the second most important blood group system,
after ABO, and it consists of 50 defined blood-
group antigens, among which the five antigens D, C,
c, E, and e are the most important. The commonly
used terms Rh factor, Rh positive and Rh
negative refer to the D antigen only.
Rh antibodies are immunoglobulin G (IgG) may cross freely from the placenta
into fetal circulation
Rh incompatibility can occur by 2 main mechanisms
1. secondary to fetomaternal hemorrhage
2. when an Rh-negative female receives an Rh-positive blood transfusion

19. Why it is important to give blood?
Anaemia is the commonest encountered abnormal
laboratory finding in critical care (Vincent et al CCM
2006)
Inadequate O2 delivery with severe anemia
RBC transfusion improves O2 delivery
Critically ill patients more susceptible to adverse
effects of oxygen depletion
• impairs oxygen delivery to critical organs
• cardiovascular system must compensate
RBC transfusion should improve outcomes

Children are quite different from adults during growth
and development, and that should be taken into
different consideration.
27. Transfusion complications
Transfusion complications that are generally common
between adult and pediatric patients include
Acute hemolytic transfusion reactions,
Febrile non-haemolytic transfusion reactions
(FNHTR)
Allergic transfusion reactions,
Delayed hemolytic transfusion reactions,
Transfusion-related acute lung injury,
Transfusion-associated graft-versus-host disease,
and
Infectious complications.
28. Blood grouping and crossmatching
Blood grouping
The most fatal of all transfusion-related reaction is ABO
incompatibility causing complement-mediated intravascular
hemolysis. Hence, correct blood grouping and typing, and cross-
checking with the blood requisition form is of utmost importance.
ABO typing is carried out by testing RBCs for the A and B antigens
and the serum for the A and B antibodies before transfusion. The
next step involves Rh typing with only 15% of the population being
Rh-negative.
Cross-matching
Cross-matching involves mixing of donor RBCs with the recipient
serum to detect fatal reactions. [19] . Among the three phases, the first
two phases are more important as they detect those involved in fatal
HTR. The total time taken for all the three phases is in between 45
and 60 min.

34. Autologous/placental RBC transfusion
In small pilot studies, there has been no benefit in autologous
transfusion in neonates as compared with standard allogeneic
transfusion.42,43 Additionally, there is limited benefit due to low
volume of collection in extremely low birth weight infants.42,44–46
The shelf-life of umbilical cord blood autologous product is also
shorter at 14–21 days.47 In addition to these concerns, bacterial
contamination and high cost continue to hamper clinical usage.42,44

The reduction in the number of leukocytes, in allogenic
blood products has been proven to be clinically
relevant in the following:
1. Reducing the frequency and severity of Febrile
Non-Hemolytic Transfusion Reactions (FNHTRs).
2. Reducing the risk of cytomegalovirus (CMV)
transmission.
3. Reducing the risk of HLA-alloimmunization and
platelet-refractoriness.

vary in the literature, although hemoglobin criteria for transfusion less
than 8 g/dl and hematocrit values less than 25% are typically reported
as restrictive.
The report suggests

45. METABOLIC CONSEQUENCES AND
COMPLICATIONS
OF MASSIVE BLOOD TRANSFUSION
The metabolic consequences of large blood transfusions also occur in adults
but are more frequent in children due to the relationship between blood
component administered and their circulating blood volume
Hypocalcaemia may be treated by administration of calcium fluoride 5-10
mg/kg IV or calcium gluconate 15-30 mg/kg. If the blood loss is continuous
and prolonged infusion of calcium chloride at the rate of10 mg/kg/h may be
used.
Hyperkalaemia Use of blood collected within 7 days and administration
slowly with total volume < 1.0 ml/kg/min is recommended. Intravenous
sodium bicarbonate 1 m mol/kg and calcium chloride 20 mg/kg or calcium
gluconate 60 mg/kg may be used to treat hyperkalaemia causing
arrhythmias. Use of intravenous dextrose insulin, hyperventilation and
sympathomimetics can be useful
HypomagnesaemiaIV magnesium sulphate administered at 25-50 mg/kg
Acid-base disorders
Hypothermia Use of blood warmers, maintaining OT temperature, use of
warming blankets and warm fluids for irrigation and intravenous infusion with
monitoring of electrocardiogram, SpO2, skin and core temperature can be
helpful in preventing hypothermia and consequent complications.

The administration of blood per se did not lead to increased
postoperative infection. Clinicians should reconsider withholding
blood transfusion in patients solely owing to concerns of
predisposition to infection.

52. In the present study, we found that shorter storage RBCs
transfusion significantly improved ChE recovery and
reduced the amount and duration of atropine usage
Нese results suggest that RBCs transfusion could
improve clinical therapeutic effects on OPs intoxication
patients. Red blood transfusion may deliver additional
erythrocyte cholinesterase, which could be the potential
target substrate for OP
packed RBCs transfusion has advantages over whole
blood transfusion, since the total volume administrated
into patients is less that could avoid risks of overloading
and fever or allergy by substances in serum
Concludes early blood transfusion can e ٴوectLvel reduce
the extent of toxic symptoms and prevent further
progression, especially when oximes are not available.
