This document provides an overview of glycolysis, including its key enzymes, intermediates, and regulation. Glycolysis involves 10 enzyme-catalyzed reactions that convert glucose to pyruvate with ATP production. It occurs in two phases: the preparatory phase uses ATP to phosphorylate glucose for cleavage, while the payoff phase generates ATP through substrate-level phosphorylation. The document lists the 10 steps of glycolysis and discusses regulation of this central glucose catabolism pathway.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

8. GLYCOLYSIS
Glycolysis comes from a merge of two Greek
words:
Glykys = sweet
Lysis = breakdown/ splitting
It is also known as Embden-Meyerhof-Parnas
pathway or EMP pathway.
9. INTRODUCTION
• GLYCOLYSIS is the sequence of 10 enzyme-
catalyzed reactions that converts glucose into
pyruvate with simultaneous production of ATP.
• In this oxidative process, 1molecule of glucose
is partially oxidised to 2 molecules of pyruvate.
• This major pathway of glucose metabolism
occurs in the cytosol of all cell.
• This unique pathway occurs aerobically as
well as anaerobically.
10. • It also includes formation of Lactate from
Pyruvate.
• The glycolytic sequence of reactions differ
from species to species only in the
mechanism of its regulation & in the
subsequent metabolic fate of the pyruvate
formed.
• In aerobic organisms, glycolysis is the
prelude to Citric acid cycle and ETC.
• Glycolysis is the central pathway for
Glucose catabolism.
12. TWO PHASES OF GLYCOLYSIS
• Glycolysis leads to breakdown of 6-C
glucose into two molecules of 3-C
pyruvate with the enzyme catalyzed
reaction or categorized into 2 phases:
1. Phase 1- preparatory phase
2. Phase 2- payoff phase.
13.
14. PREPARATORY PHASE
• It consists of the 1st 5 steps of glycolysis in
which the glucose is enzymatically
phosphorylated by ATP to yield Fructose-1,6-
biphosphate.
• This fructuse-1,6-biphosphate is then split in
half to yield 2 molecules of 3-carbon
containing Glyceraldehyde-3-phosphate/
dihyroxyacteone phosphate.
15. • Thus the first phase results in cleavage of
the hexose chain.
• This cleavage requires an investment of 2
ATP molecules to activate the glucose
molecule and prepare it for its cleavage
into 3-carbon compound.
16.
17. PAYOFF PHASE
• This phase constitutes the last 5
reactions of Glycolysis.
• This phase marks the release of ATP
molecules during conversion of
Glyceraldehyde-3-phosphtae to 2 moles of
Pyruvate.
• Here 4 moles of ADP are phosphorylated to
ATP. Although 4 moles of ATP are formed, the
net result is only 2 molecules of ATP per mole
of Glucose oxidized, since 2 moles of ATP are
utilized in Phase 1.
20. STEP 1: PHOSPHORYLATION
Glucose
• Glucose is phosphorylated by ATP to form
sugar phosphate.
• This is an irreversible reaction & is catalyzed
by hexokinase.
• Thus the reaction can be represented as
follows:
Glucose-6-phosphate
Hexokinase
ATP
ADP
21. STEP 2: ISOMERIZATION
• It is a reversible rearrangement of chemical
structure of carbonyl oxygen from C1 to C2,
forming a Ketose from the Aldose.
• Thus, isomerization of the aldose
Glucose6-phosphate gives the ketose,
Fructose-6-phoshphate.
Glucose-6-phosphate
Phosphoglucoisomerase
Fructose-6-phosphate
22. STEP 3: PHOPHORYLATION
Here the Fructose-6-phosphate is phosphorylated
by ATP to fructose-1,6-bisphosphate.
This is an irreversible reaction and is catalyzed by
phosphofructokinase enzyme.
Fructose-6-phosphate
Fructose-1,6-bisphosphate
ATP
ADP
Phosphofructokinase
23. STEP 4: BREAKDOWN
• This six carbon sugar is cleaved to produce
two 3-C molecules: glyceradldehyde-3-
phosphate (GAP) & dihydroxyacetone
phosphate(DHAP).
• This reaction is catalyzed by Aldolase.
Glyceraldehyde
-3-
phosphate
Dihydroxyacetone
phosphate
Triose
phosphate
isomerase
Fructose-1,6-
bisphosphate
Aldolase
24. STEP 5: ISOMERIZATION
• Dihydroxyacetone phosphate is oxidized to form
Glyceraldehyde-3-phosphate.
• This reaction is catalyzed by triose phosphate
isomerase enzyme.
Glyceraldehyde-3-phosphate
Dihydroxyacetone phosphate
Triose
phosphate
isomerase
25. STEP 6
• 2 molecules of Glyceraldehyde-3-
phosphate are oxidized.
• Glyceraldehyde-3-phosphate
dehydrogenase catalyzes the
conversion of Glyceraldehyde3-
phosphate into 1,3-
bisphosphoglycerate.
27. STEP 7
• The transfer of high-energy phosphate group
that was generated earlier to ADP, form ATP.
• This phosphorylation i.e. addition of
phosphate to ADP to give ATP is termed as
substrate level phosphorylation as the
phosphate donor is the substrate 1,3-
bisphosphoglycerate (1,3-BPG).
• The product of this reaction is 2 molecules of
3-phosphoglycerate.
29. STEP 8
• The remaining phosphate-ester linkage in 3-
phosphoglycerate, is moved from carbon 3 to
carbon 2 ,because of relatively low free
energy of hydrolysis, to form 2-
phosphoglycerate(2-PG).
3-phosphoglycerate
2-phosphoglycerate
Phosphoglycerate
mutase
30. STEP 9: DEHYDRATION OF 2-PG
• This is the second reaction in glycolysis
where a high-energy phosphate compound
is formed.
• The 2-phosphoglycerate is dehydrated by the
action of enolase to
phosphoenolpyruvate(PEP).
• This is a reversible reaction.
32. STEP 10: TRANSFER OF PHOSPHATE
FROM PEP to pyruvate
• This last step is the irreversible transfer of
high energy phosphoryl group from
phosphoenolpuruvate to pyruvate.
• This reaction is catalyzed by pyruvate
kinase.
• This is the 2nd substrate level
phosphorylation
reaction in glycolysis which yields ATP.
