vindoline effectively ameliorated diabetes induced hepatotoxicity by docking oxidative oxidative stress, inflammation and hyperglycemia in type 2 diabetes rat
Glucagon like peptide-1 (GLP-1) is an incretin secretory molecule. GLP-1 receptor agonists (GLP-1RAs) are widely used in the treatment of type 2 diabetes (T2DM) due to their attributes such as body weight loss, protection of islet β cells, promotion of islet β cell proliferation and minimal side effects. Studies have found that GLP-1R is widely distributed on pancreatic and other tissues and has multiple biological effects, such as reducing neuroinflammation, promoting nerve growth, improving heart function, suppressing appetite, delaying gastric emptying, regulating blood lipid metabolism and reducing fat deposition. Moreover, GLP-1RAs have neuroprotective, anti-infectious, cardiovascular protective, and metabolic regulatory effects, exhibiting good application prospects. Growing attention has been paid to the relationship between GLP-1RAs and tumorigenesis, development and prognosis in patient with T2DM. Here, we reviewed the therapeutic effects and possible mechanisms of action of GLP-1RAs in the nervous, cardiovascular, and endocrine systems and their correlation with metabolism, tumours and other diseases.

Crimson Publishers: Dietary Supplements as a Possible Trigger of Autoimmune H...CrimsonGastroenterology
Introduction: Autoimmune hepatitis (AIH) etiology remains unknown, but in genetically predisposed individuals, diverse agents may trigger the disease. Herbal and drug induced AIH have been reported in recent years probable due to the increase in self-medication. More studies are necessary to define if drugs and herbal/dietary supplements unmask and induce AIH or drug-induced hepatitis with autoimmune features.
Purpose: We report an autoimmune hepatitis case possibly induced by herbal/dietary supplements intake.
Case-report: A 55-year-old female presented with a 15-day course of jaundice and increased aminotransferases. Immunologic panel showed antinuclear antibody titer of 1:320 and serum immunoglobulin G (IgG) level approximately 2 times the upper limit of normal. She reported regular daily ingestion of Herbalife® products for 6 months which were discontinued when symptoms began. Laboratory tests worsened despite the fact that patient had stopped supplements usage, and a liver biopsy was performed. Histology was suggestive of both AIH and drug induced liver disease. The patient fulfilled criteria for probable AIH based on the revised criteria for diagnosing autoimmune hepatitis, and improved with prednisolone and azathioprine therapy, with progressive laboratory improvement and symptoms remission.
Discussion: Herbal/dietary supplements induced AIH has been previously reported, but the causality is not yet well established. Worsening of aminotransferases despite supplement suspension, histological findings and favorable response with corticosteroid treatment, supported the hypothesis of AIH induced by the used supplement. This case report aims to demonstrate the possible causality between herbal/dietary supplements and liver injury, including autoimmune hepatitis.

Aqueous extract of Phaseolus Vulgaris L. (Red Kidney Beans) was investigated for its effects in
alloxan induced-diabetic rats. Twenty four albino rats were randomly allocated into four groups (A-D) of six
rats each such that group A (diabetes control) received 0.5 mL distilled water, group B (diabetes) received
400 mg/kg bwt of extract, group C (normal control) received 0.5 mL of distilled water while group D (normal)
received 400 mg/kg bwt of extract, all extract were orally administered once daily for 14 days. Diabetes was
induced in groups A&B by single interperitonial injection of 150 mg/kg alloxan monohydrate. Phytochemical
screening indicated the presence of alkaloids, balsam, flavonoids, saponins, tannins, cyanogenic glycosides,
terpenes and steroids. The hypoglyceamic potential of Phasoelus vulgaris L. was expressed in diabetes
treated rats. Blood glucose, total protein, albumin and cholesterol levels of the diabetes treated rats and
normal treated rats were not significantly (p>0.05) altered when compared with the control rats. However,
these values were significantly (p<0.05)><0.05)>0.05) effects on PCV and Hb in all groups when compared to the normal control. The study showed that
the aqueous extract of Phasoelus vulgaris L. leaves possess hypoglycaemic, antidiabetic properties and
ameliorating the high levels of marker enzymes observed in diabetes untreated rats.

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia and its occurrence is increasing fast in most of the countries. Herbal medicine derived from plant extracts have been utilized increasingly for the treatment of various disorders like diabetes mellitus. The present study was designed to evaluate the anti diabetic activity of ‘Herbamed’, a herbal formulation composed of Vernonia amygdalina, Ocimum gratissimum, Zingiber officinale and Allium sativum in alloxan-induced diabetic rats model.
The effects of dietary fats on the risk of coronary artery disease (CAD) have traditionally
been estimated from their effects on LDL cholesterol. Fats, however, also affect HDL
cholesterol, and the ratio of total to HDL cholesterol is a more specific marker of CAD than is
LDL cholesterol. Hypolipidemic drugs and fruits can play a part to reduce LDL particles
decreasing chances of CAD development. This study was conducted to compare
hypolipidemic effects of Niacin and Jujube fruit in primary as well as secondary
hyperlipidemic patients. Study was conducted from November 2018 to February 2019 at
Jinnah Hospital Lahore. Sixty participants were enrolled of both gender male and female
patients age range from 20 to 70 years. Consent was taken from all patients. They were
divided in two groups. Group-I was advised to take 2 grams Niacin in divided doses for the
period of two months. Group-II was advised to take 500 grams of fruit Jujube daily for the
period of two months. Their baseline LDL and HDL cholesterol was determined by
conventional method of measuring Lipid Profile. After two months therapy, their post
treatment lipid profile was measured and mean values with ± SEM were analyzed
biostatistically. Group-I which was on Niacin their LDL cholesterol decreased significantly and
HDL cholesterol was increased significantly. In group-II patients LDL cholesterol was
decreased significantly but HDL increase was not significant with p-value of >0.05. It was
concluded from the research work that Niacin is potent in lowering LDL and increasing HDL
cholesterol, while Jujube has significant effect as LDL cholesterol lowering potential, but it
does not increase HDL cholesterol significantly.

Cissus quadrangularis L. (hadjod) and Trigonella foenum-graecum L. (fenugreek) plant parts are used for fracture healing and as an antidiabetic agent, respectively in traditional medicine. This study aimed to investigate the efficacy of C. quadrangularis stem bark extract (CQ) and T. foenum-graecum seed extract (TFG) therapy for the treatment of type I diabetes induced osteopenia. Alloxan (dissolved in 0.1 M citrate buffer (pH = 4.5); intraperitoneally injected @ 130 mg/kg body weight) induced type I diabetic rats were treated with individual and combined doses of ethanol extracts of CQ and TFG for consecutive 30 days @ 250 and 500 mg per kg body weight, orally. Insulin (0.5 IU/kg body weight) was chosen as standard. Body weight and fasting blood glucose were recorded. Two-dimensional (2D) and three-dimensional (3D) analysis of the femur and tibia were performed using micro-computed tomography (µCT) scan to measure histomorphometric parameters of trabecular and cortical regions and bone mineral density (BMD). Elevated level of fasting blood glucose was restored to the vehicle-treated group after treatment with CQ and TFG. Both the extracts significantly improved trabecular histomorphometric parameters, viz. BMD, percent bone volume, trabecular number, trabecular separation, connection density. Cortical mean total cross-sectional bone area, cross-sectional thickness, mean total cross-sectional tissue area were comparable to the vehicle-treated group. CQ and TFG combination therapy showed a marked improvement in bone microarchitecture and can be given together as a potential alternative medicine to insulin for prevention of type I diabetes induced osteopathy. Therefore, it can be considered in the management of diabetic osteopathy in humans.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

4. Introduction
Diabetes mellitus (DM) is a chronic diseases that has become a global health
threat.
According to the World Health Organisation (WHO) 2016 report an estimate of
422 million people globally were diagnosed with DM in 2014 while a 108 million
had diabetes in 1980.
DM is also one of the four most common non-communicable-diseases and
currently the seventh leading cause of morbidity and mortality globally.
high mortality rate is associated with complications such as diabetic liver disease
(DLD) which progressively develop in these patients. Liver cirrhosis,
steatohepatitis, non-alcoholic fatty liver disease (NAFLD) and hepatic carcinomas
are examples of different spectrums of DLDs that are observed in T2DM patients
with persistent hyperglycaemia

5. Cont..
DLDs primarily develop as a consequence of hyperglycaemia, hypertriglyceridemia and insulin
resistance
Therapeutic strategies which can efficiently prevent or reverse the adverse effects of prolonged
oxidative stress and inflammation in DM may be highly beneficial in preventing diabetic
complications such as DLDs
A major drawback of oral antidiabetic agents is their failure to effectively cure diabetes; moreover,
they have been associated with increased side effects.
In this regard, medicinal plants appear as promising therapeutic avenues motivated by the presence of
phytoconstituents that have numerous health benefits and may act as precursors in drug formulation

6. Drug Profile
Catharanthus roseus or Vinca rosea / Madagascar periwinkle
Family – Apocynaceae
Genus – Catharatnhus
Species – C. Roseus
Traditionally, it was used to treat diseases like cancer, malaria, diabetes, insomnia and high blood
pressure.
presence of indole alkaloids, flavonoids, beta sitosterol, quercetin.
Vindoline is an indole alkaloid extracted from C. roseus which was recently been reported to possess
protein-tyrosine phosphatase 1B (PTP-1B) inhibitory effects and therefore may serve as an “insulin
sensitizer” in the management of T2DM

8. Aims & Objective
Antioxidant analysis.
Histopathological studies.
To evaluate the effect of vindoline in hepatotoxicity induced by T2DM
conditions using glibenclamide as reference drug.

9. Materials and Methods
Animal :
Fortyeight (48), weight : (190–230 g)
Six weeks old male Wistar Rats
Plant-derived chemical and standard drug
Vindoline was purchased from the manufacturer: Best of Chemicals
(BOC) Sciences, USA).
The standard drug : glibenclamide was purchased from a local pharmacy.
9
10. Experimental design
Rats were randomly divided into six groups (n = 8)
Group N: normal control administered with vehicle only;
Group NV: normal treated group administered with vindoline (20 mg/kg b.w);
Group NG: normal treated group treated with glibenclamide (5 mg/ kg b.w).
DC: diabetic control group administered with vehicle;
Group DV: diabetic treated with 20 mg/kg b.w of vindoline;
Group DM: diabetic treated with 5 mg/kg b.w of glibenclamide;

11. Timeline
Duration – 56 days (8weeks)
T2DM was induced in rats by having them drink 10% fructose solution ad
libitum for 14 days
On day 15, STZ, 40 mg/kg.
5 days gap.
Daily treatment for 36 days.
After the 8 week study period, Rats were anaesthetised and euthanized using
isoflurane gas.

Determination of the relative liver weights
Relative liver weight = (liver weight ÷ total body weight) 100g
Liver function enzymes activity
Aspartate amino transferase (AST),
Alanine amino transferase (ALT),
Alkaline phosphatase (ALP) were measured using ABX PENTRA 400 automated
chemistry analyser machine.

14. Statistical analysis
Results were analysed using GRAPH PAD Prism software package,
Version 5.0.
The comparisons within groups were determined by using the one way
analysis of variance (ANOVA).

19. Conclusion
experimental findings suggest that vindoline as a plant-derived
product may be of great relevance in the treatment of diabetes
mellitus and its complications owing to its anti-hyperglycemic,
antihyperlipidemic, anti-inflammatory and antioxidant activities.
