Water Melon: Nature's Formidable Defence Against A Host Of Diseases

                Watermelon intake has demonstrated effects on blood pressure regulation along with other health benefits. Even consuming watermelon frequently as a dessert, fruit salad and in garnishing drinks could remediate metabolic complications that come with junk foods and a Western-style diet high in fat.

 

Experts, in a new study, said supplementing a diet high in fat with watermelon as a dessert, fruit salad and in garnishing drinks diet improved fasting blood glucose, circulating insulin concentrations in the blood, and changes in liver metabolite accumulation.

 

Even with a modest level of supplementation, the fiber-rich additives further improved glucose breakdown and energy efficiency. It was in the March 2020 edition of The Journal of Nutrition.

 

Watermelon is an unusual fruit source of the lycopene and an excellent source of water. It contains unusual amounts of the amino acids and citrulline. Also, watermelon is an excellent source of immune-supportive vitamin C and vitamin A (9.0 mg), potassium (11.2 mg) and magnesium (10.2 mg).

 

A plethora of evidence shows that it can be effective for weight loss because of its fewer quantities of fats.  As a result, the consumption of watermelon provides long-term health benefits such as reduced risk of heart disease, improved blood pressure in hypertension patients and decrease low-density lipoprotein (LDL) oxidation.

 

The researchers had assessed the intake of watermelon in high-fat–fed male mice. Ten-week-old male mice were provided either a low-fat diet or a high fat diet with watermelon skin or watermelon skin and rind were added at 2.25 per cent of diet. Body weights, food intake and glucose tolerance were determined.

 

The final body weight of the low fat control group was significantly lower than that of the high fat-fed control group. Mice in treatment groups fed high fat supplemented with watermelon products had final body weights similar to those of the high fat-fed control mice.

 

 

Insulin concentrations in the blood were reduced by approximately 40 per cent in mice fed a high fat diet with watermelon rind supplementation compared with mice fed a high fat diet alone. Depending on the individual species or group, microbiome populations changed significantly.

 

Moreover, in another study researchers had corroborated the antidiabetic potential of watermelon juice in alloxan-induced diabetic rats and declared that its juice may have a useful clinical application in the management of diabetes mellitus and its metabolic complications if developed as adjuvant therapy.  It was in the April 2020 edition of the Journal of Diabetes & Metabolic Disorders.

 

Diabetes was induced in the rats and these animals were randomly grouped into five groups of normal control, untreated diabetic control, diabetic rats administered 200 mg/kg body weight of metformin, diabetic rats administered 500 mg/kg body weight of watermelon juice and diabetic rats administered 1000 mg/kg body weight of watermelon juice. The rats were sacrificed on the 14th day of the experiment and various parameters were also evaluated in their blood and body tissues.

 

The watermelon juice exhibits anti-oxidant properties in a dose-dependent manner. Added to this, the administration of different doses of the watermelon juice significantly reduced the fasting blood glucose level, level of fat in the blood and glucose-6-phosphatase in these rats made to develop diabetes under laboratory conditions.

 

Also, watermelon-starfruit Juice is also used traditionally for reducing blood pressure of hypertension in Indonesia. Expert’s in a test to determine the best therapeutic juice in reducing hypertension found watermelon, starfruit, and watermelon-starfruit mixture all have the same ability to reduce blood pressure. But the watermelon-star fruit juice was the best in reducing high blood pressure.

 

A sample of 33 people was selected and divided into three equal groups, namely drinking watermelon juice, drinking star fruit juice, and drinking watermelon-star fruit juice mixture group. It was in the 2020 edition of the SRP journal.

 

According to the study, the mean systolic blood pressure of the three groups before and after drinking juice showed a significant difference. Likewise, the mean diastolic blood pressure of the three groups before and after drinking juice showed a significant difference.

 

 

They added “all three groups have the same ability to reduce blood pressure, but the watermelon-star fruit juice group can reduce high blood pressure (hypertension) to become normal (norm tension).”

New Findings On Herbal Cure For Snake Bite

Snakes have always been a major pest posing a potential threat to humans from time immemorial. Plant-based repellents like lemongrass, bitter kola seeds, tobacco leaf, scent leaf and chilli pepper seeds have been used for generations as protective measures against snakes within homestead and other environments.

 

Despite these, ill health and deaths from snake infestation have continued to be a challenge, with heavy reliance on the use of synthetic antisnake venom. This has proved to be costly and in short supply. Some anti-venom medications also have adverse effects like shortness of breath, weak pulse, muscle tenderness, dizziness, fainting, and, in some cases, death due to bleeding.

 

On the other hand, traditional medicine in many countries employs the extracts of certain plants to provide protection against snake bites. They are cheap, easily available, and stable at room temperature and could neutralize a wide range of venom antigen without side effects.

 

For instance, Mucuna pruriens, (commonly referred to as velvet bean, agbala or agbaloko in Ibo and werepe in Yoruba) is well known for its anti-snake venom properties.  Eating few of its seeds is claimed to confer protection against snake bite in an individual for at least a year.

 

Now, researchers, investigating the extracts of Mucuna pruriens seed and Mimosa pudica root on venoms of Naja nigricollis (black-necked spitting cobra) and Bitis arietans (puff adder), said they may also be considered as promising anti-venom agents for people living in a snake-bite prone environment. Anti-venom acts by neutralizing snake venom that has entered the body.

 

Mimosa pudica is commonly called ‘touch-me-not’, kpakochuku in Igbo, patanmo in Yoruba.

 

In mice, at a concentration of 50 mg/ml, both plant extracts were found to neutralize the fibrinolysis (preventing blood clots occurring naturally and so causing problems) effect of the Naja nigricollis venom, but 400 mg/ml was required to neutralize the fibrinolysis effect of Bitis arietans.

 

Also, 50 mg/ml concentration of M. pruriens extract suppressed the haemolysis (breaking down of blood cells) caused by N. nigricollis venom by 70 per cent but at the same concentration, M. pudica extract reduced haemolysis by 49.4 per cent.

 

The 2020 study, in the journal, Recent Patents on Biotechnology, involved Matthew P. Ameh, Mamman Mohammed, Yusuf P. Ofemile, Magaji G Mohammed  and Ada Gabriel at the Ahmadu Bello University, Zaria in conjunction  with Akefe O. Isaac at the Queensland Brain Institute, The University of Queensland, Brisbane, Australia.

 

Before now, experts had suggested that the protective activity of Mucuna pruriens seeds protects against snake bite through the stimulation of antibodies that cross-react with venom toxins, thus the merit of the idea that its seed consumption can provide long-term protection against snake bite.

 

The study in the Journal of Biological Chemistry had identified a specific protein, MP-4, as that which reacts with antibodies the body had developed against Echis carinatus (saw-scaled viper) venom, thus strengthening the idea that the protective function is immunological.

 

Furthermore, mice immunized with MP-4, they found, showed significantly higher rates of survival than unimmunized mice when challenged with Echis carinatus venom.

 

Moreover, in another study, researchers reported the protective effect of M. pruriens seed extract against cobra (Javan spitting cobra) venom causing permanent damage to the heart.  In the journal, Evidence-Based Complementary and Alternative Medicine, they suggested that the extract renders the heart more resistant to the toxic effect of the venom as well as help to boost the body’s immunity against the deadly venom.

 

Recent studies have found that Mucuna pruriens leaves are more effective than the standard drug, anti-venin, for curing snakebite. The study published in the International Journal of Biochemistry Research & Review investigated the anti-venom activity of Mucuna pruriens leaves extract against cobra (Naja hannah) venom.

 

 

However, scientists have recently validated some local plant as herbal medicines for snakebite management. These include English wild custard apple (Annona senegalensis), turmeric (Curcuma longa) and plantain (Musa paradiasica).

 

Annona senegalensis is commonly called English wild custard apple, tàllàfà màraàyú in Hausa; uburu-ọcha in Ibo; àbo and arere in Yoruba.

 

Researchers at the University of Maiduguri, Borno State, said in the Journal of Pharmacology and Biomedical Sciences that the root extract of Annona senegalensis possesses potent snake venom-neutralising capacity against the Bitisarietans venom and could be used for therapeutic purposes in case of snakebite.

Why Pregnant Women Should Avoid Moringa Leaves

Moringa leaf is used to tackle malnutrition, boost the immune system and enhance breast milk production in resource-limited settings. Now, experts have warned that it is not safe at conception and during pregnancy because it can be inimical to fetal development.

 

In a new study, researchers investigated the effect of the intake of low amounts of moringa leaves before conception attempts as well as its effect during conception under laboratory conditions and found it can cause contraction of the womb with varying intensities.

 

According to the study, both the cold and hot moringa leave extracts significantly produced contraction of the womb with varying intensities. It also indicated that it had anti-infertility properties.

 

For the study, the researchers assessed both the cold and hot moringa leave extracts on samples of womb obtained from non-pregnant female animals as well as female Wistar rats in the laboratory. The contractile force of the muscles strips from the womb of the non-pregnant female animals was measured. Also, pregnancy length, delayed labour, mortality and birth complications in the Wistar rats were monitored.

 

Cold moringa leaf extract administered before and after mating, respectively produced 100 per cent and 80 per cent inhibition of conception, while 96.6 per cent and 58 per cent effect was comparatively produced by its hot extracts.

 

The 2019 study entitled, “Aqueous extract of Moringa oleifera leaf used in Nigerian ethnomedicine alters conception and some pregnancy outcomes in Wistar rat,” was published in the South African Journal of Botany. It involved A.F. Attah; J.O. Moody; M.A. Sonibare; H.H. Salahdeen; O.O. Akindele; P.O. Nnamani; O.A. Diyaolu and Y. Raji.

 

In this study, none of the extracts prevented the animals from mating and this suggests that the animals’ cycles contained at least one estrus during the two weeks of mating although this does not supply any information about the regularity of the cycle.

 

 

Studies in the recent past have shown that about 50 per cent of human conception get aborted or do not result in successful delivery. Standard methods that have been frequently used to detect early gestational evidence have demonstrated that between 32 per cent and 42per cent of pregnancies do not progress to parturition as a result of a miscarriage. Many factors may be tied to this including the consumption of unknown plants that can cause abortion.

 

The leaf of the plant has additionally been reported to be used in the Central African Republic to induce uterine contraction and facilitate childbirth. Also, in northern Nigeria, its fresh leaves are a component of a local meal made up of powdered groundnut cake, chilli, sweeteners, and local roasted beef called “Suya”.

 

Likewise, Nigerian women, especially those from northern geopolitical extraction is known for its intake to increase breast milk. Moreover, there limited scientific documentation of lactating women not getting pregnant during the period of its accelerated intake despite unprotected sexual activity, and raising the question about its potential usefulness as nutritional cum child-spacing supplement.

 

The high nutritional content of Moringa leaves has also attracted much interest due to the levels of vitamin A, vitamin C, calcium, iron, potassium and adequately high protein quality which contends with that of milk and eggs.

 

The researchers, however, declared that the cold extract seemed to have a more adverse effect on the maintenance of pregnancy possibly because of the presence of unfriendly metabolites which have not been inactivated partially or completely by heat. The pups born to the hot extract group had severely altered morphometry which suggests that the growth and development of these pups have been compromised during the gestation period.

 

They suggested that the interference with the physiology and the function of the reproductive system may have been triggered by an alteration in the synthesis of hormones, storage, liberation, transport or excretion.

 

Several indigenous plant extracts have been described to possess chemical substances that can alter the smooth release of reproductive hormones culminating in the inhibition of conception or the contraction of the womb.

The Effects Of Corona Virus On Men's Infertility

Corona virus infection may lead to infertility in men even if they only suffer a mild form of the disease. This development came about after an Israeli study found that the sperm counts of infected men halved 30 days after they were diagnosed with COVID-19. The study conducted at the Sheba Medical Centre in Tel Aviv, also alleged sperm motility—or its ability to move by itself—was also hampered. But scientists insist the truth on whether Covid-19 permanently damages fertility is still unclear and that even flu causes a temporary drop in sperm counts. According to the report in the journal of Fertility and Sterility, the claims that the changes were seen in men with mild cases did not address how many people were involved. Scientists studying the effect of coronavirus on fertility have made similar claims in the past, but doctors insist reports of men having lower sperm counts are likely down to them having had a fever which is a tell-tale symptom of coronavirus, which makes it harder for the body to produce sperm. They also argue that production can bounce back after an infection has passed. Professor Allan Pacey, an andrologist at the University of Sheffield and former chair of the British Fertility Society said coronavirus may cause a temporary drop in sperm production. But it is not confirmed whether or not the effect could be long-lasting, harming the fertility of men. Pacey said people who get coronavirus are probably quite unwell, and that even influenza will cause a decline in sperm count temporarily, but that the question is whether it is permanent and whether it is recoverable. Research is yet to reveal whether long-term damage can be caused to testicles by coronavirus, and it could take several years before scientists have the answer. Previous research has indicated, however, that any damage caused to the testes by an infection is not long-term. Pacey cautioned against the finding in the new Israeli research that coronavirus can damage cells in the testicles responsible for making semen and the male hormone testosterone.

How Consumption Of Fruit Juice At Young Age Benefits Children Later In Life

New research has shown that consumption of 100 per cent fruit juice by children aged two to 18 years is closely linked to improved nutrient adequacy during their formative years.

 

Drinking 100 per cent fruit juices play an important role in the diets of young children by supplying them with the important nutrients during these crucial years of growth and development.

 

The research found that young children who regularly consumed 100 per cent fruit juice at a young age went on to eat more fruits and vegetables and were more likely to develop healthier diets and eating habits in their teenage years than their peers who drank much less fruit juice when they were younger.

 

The study titled ‘A longitudinal study of fruit juice consumption during the preschool years and subsequent diet quality and BMI’ was carried out by Boston University and published online at BMC Nutrition in May 2020.

 

The results of the study encouraged the inclusion of 100 per cent fruit juice as part of an overall balanced diet, whilst stressing that contrary to previous research, regular consumption of fruit juices did not put children at a greater risk of being overweight in later years.

 

The study also mentioned the required daily quantity, calling out that it is also important for pre-school and nursery age children to drink at least one and a half cups of 100 per cent pure fruit juice every day.

 

The study stated that 100 per cent fruit juice can help meet recommended daily goals for fruit intake because it is a nutrient-dense drink that provides vitamins, minerals (folic acid, thiamine and magnesium) and beneficial plant nutrients like polyphenols.

 

Lead researcher, Dr Lynn Moore from Boston University, U.S.A., said, “Fruit consumption, particularly whole fruit consumption, has many health benefits throughout one’s lifespan. Avoiding fruit juice during these early formative years may have unintended effects on evolving dietary behaviours. Fruit juice drinking in young children may promote better diet quality and higher intakes of whole fruit,” he said.

 

He added that the benefits associated with moderate intake of 100 per cent fruit juice were not accompanied by any adverse effects on childhood weight.

 

In Nigeria, one brand that is at the forefront of promoting the nutritional benefits of 100 per cent fruit juice is Chivita which is renowned for its high quality, nourishing benefits and refreshing taste.  It contains no added sugar, no preservatives, and no artificial colours or artificial flavours.

 

A 100ml glass of its Apple variant contains 99 per cent of the Recommended Dietary Allowance (RDA) for Vitamin B1. A 100ml glass of its Orange variant contains 21 per cent of the RDA for Vitamin C. These juice variants also contain various quantities of Vitamin B3, Calcium, Iron, and Magnesium, key nutrients required for maintaining a healthy life.

Corona Virus Can Survive On Surfaces For 28 Days - New Study

            

The novel corona virus (SARS-CoV-2) that causes COVID-19 can survive on banknotes, mobile phone screens, and stainless steel for up to 28 days under laboratory conditions, according to a new study conducted by researchers at Australia’s National Science Agency who said the finding reinforced the need for disinfecting surfaces and washing hands. Until now, laboratory tests showed SARS-Cov-2 could survive for between two and three days on glass, currency notes and glass, and a maximum of 6 days on stainless and plastic.

The researchers said that at room temperature, the virus was particularly “robust,” surviving on glass surfaces such as a phone screen and on plastic banknotes but was less robust on porous surfaces such as cotton. The study was carried out in the dark as research has shown that ultraviolet light can kill the virus. The corona virus also survived for fewer days at temperatures exceeding 30 or 40 degrees Celsius.

lia’s  National Science Agency’s chief executive, Dr Larry Marshall noted: “Establishing how long the virus really remains viable on surfaces enables us to more accurately predict and mitigate its spread, and do a better job of protecting our people.” In April, the World Health Organization, WHO, had said that the corona virus could survive for 72 hours on plastic and steel and 24 hours on cardboard. But experts say people are more likely to contract the virus from someone an infected person through sneezing, coughing, and talking close to each other rather than from a surface.

According to the US Centres for Disease Control and Prevention, in rare cases, the corona virus can linger in the air for hours and infect people more than two metres apart. According to the research published in Virology Journal similarly discovered that SARS-Cov-2 remained alive at a shorter live span under hotter temperatures than cooler temperatures; it became non-infectious in 24 hours at 40C on some surfaces.

Previous research has proven that the virus might be infectious in airborne particles for over three hours but did not confirm the extent to which it can spread through surfaces like banknotes and touchscreens.
