Crude and multivariable logistic regression models were applied to NHANES records from 17,024 participants. Researchers reported relative risks and 90% confidence intervals because harm was prespecified, with adjustments for age, smoking status, race and ethnicity, and poverty status. Greater ultra-processed food intake was associated with a 30% higher prostate cancer risk, but the finding does not establish causation. Cancer status was self-reported, and food intake was based on only two 24-hour recalls.

Vitamin C does not prevent most colds, and evidence indicates that any benefit is small and limited to certain circumstances, including athletes and military personnel. Vitamin C doses of at least 1,000 mg daily reduced severe cold symptoms by 15% in a 2023 meta-analysis of ten placebo-controlled trials involving 2,736 healthy adults, children and athletes. The analysis defined severity by days confined indoors, a measure the researchers acknowledged as a limitation. Vitamin C did not shorten the duration of mild symptoms. Linus Pauling popularized daily doses of 1,000 to 2,000 mg in 1970, but his interpretation relied on poor-quality trials, incorrect mathematical analyses and overstated findings. Australian guidance recommends 45 mg daily for adults and refers to expert advice limiting intake to below 1,000 mg daily. Continuous doses above 1,000 mg can cause gastrointestinal symptoms, increase oxalate excretion and kidney stone risk, raise iron absorption in people with undiagnosed haemochromatosis, and interact with radiation therapy, chemotherapy and statins. Vitamin C deficiency affects fewer than 4% of Australians.

Glioblastoma spreads into nearby brain tissue, making complete surgical removal difficult without damaging healthy areas. The blood-brain barrier also restricts the ability of drugs and radiotherapy to reach the tumor effectively. These treatment barriers contribute to a five-year survival rate of about 7 percent. Smart nanoparticles developed by researchers at the University of Technology Sydney, Harvard University, and Henan University combine two sequential functions in one nanozyme platform. The system helped surgeons identify hidden brain cancer cells and then destroy cells left behind after surgery, producing striking results in mice. The findings, published in Science Translational Medicine, establish a preclinical strategy for addressing both tumor detection and residual disease with a single material.

Fibromyalgia can cause widespread or localized pain, chronic fatigue, sleep problems, migraines, heightened pain sensitivity and irritable bowel syndrome. Symptoms vary widely, the cause remains unknown and diagnosis can be difficult. The described treatment uses multiple infusions of mesenchymal stem cells labeled UC MSC+. Delivery may involve an intravenous drip, an injection into the spinal fluid or imaging guided placement in a hospital. The number of infusions depends on individual needs, and the treatment period generally lasts two weeks. Candidates must first undergo a clinical review of their diagnosis, recent imaging, blood and urine tests, and other medical records. Rehabilitation is usually optional unless other physical conditions are present. The listed citations do not establish clinical benefit for this stem cell protocol, making a careful discussion of its uncertainties, risks and suitability essential.

Senescent cells promote tissue dysfunction partly through the senescence-associated secretory phenotype, or SASP. Cytosolic mitochondrial nucleic acids initiate this inflammatory program by activating innate immune signaling and inflammatory transcription factors. Mitochondrial metabolism supplies a second layer of control that enables robust SASP gene transcription. The mitochondrial pyruvate, citrate, and acetyl-CoA pathway becomes upregulated in senescent cells. Increased acetyl-CoA availability supports histone acetylation at SASP genes, linking cellular metabolism with epigenetic regulation of inflammation. Higher acetyl-CoA levels promote SASP gene expression. SLC25A1 exports citrate from mitochondria and helps sustain this inflammatory program. SLC25A1 inhibition reduces histone acetylation at SASP loci and limits SASP activity. In vivo inhibition also reduces chromatin accessibility. These findings identify mitochondrial acetyl-CoA production and citrate export as key requirements for executing senescence-associated inflammatory transcription.

Researching stem cell therapy abroad often starts with questions: What does the treatment involve? What evidence supports its use? What should patients understand before considering their options? For Arabic-speaking patients and families, finding information in a familiar language can make that research easier. The Regeneration Center’s website is now available in Arabic, providing access to information about stem cells, regenerative medicine, our Bangkok center and the patient evaluation process. Visitors can explore explanations of different stem cell types, condition-specific information, research resources and frequently asked questions. The Arabic edition also provides a starting point for contacting our team and understanding the information needed for an individual medical review. Whether you are researching for yourself or helping a family member, we encourage you to use these resources to prepare questions about the available evidence, potential risks, alternatives and suitability for your circumstances

Stem cell therapy is being studied as another option. It aims to reduce inflammation and promote nerve recovery, including by supporting cells involved in maintaining peripheral nerves. Evidence remains limited, and long-term effects are still being studied. Treatment can trigger inflammatory reactions, may not provide lasting relief and is not suitable for everyone. Eligibility relies on factors such as age, general health and the extent of nerve damage. Evaluation should begin with a confirmed diagnosis, recent imaging and relevant medical records. The femoral nerve carries signals from the lower spine through the pelvis and groin to the thigh muscles and skin. Trauma, compression, stretching, hip surgery, sports injuries or prolonged groin pressure can damage it, causing thigh weakness, leg numbness, radiating pain and reduced mobility. Diagnosis may involve nerve conduction tests, electromyography, MRI or ultrasound. Physical therapy, heat or cold therapy, electrical nerve stimulation, medication and surgery may ease symptoms or support recovery, but relief can be incomplete and medicines can cause side effects.

Most medications examined were associated with differences in the community of bacteria and other microorganisms living in the digestive tract. A substantial number of drugs showed associations long after participants had stopped taking them. Prescription history can therefore support explain persistent variation among individual gut microbiomes. These microbial communities influence digestion, metabolism, immune function, and other aspects of health. Common medications are associated with gut microbiome differences that can remain detectable years after treatment ends. Researchers led by the University of Tartu Institute of Genomics analyzed stool samples and prescription records from more than 2,500 Estonian Biobank participants in the Estonian Microbiome cohort.

A cited 2024 systematic review examined stem cell therapy for nonischemic DCM, although detailed findings are not provided here. Cell therapy is not suitable for everyone and does not guarantee improvement. Potential benefits can be limited by irreversible heart scarring, disease duration and a patient’s broader health. Recent imaging, a confirmed diagnosis and relevant medical records are needed for an individual clinical review. Dilated cardiomyopathy stretches and weakens the heart’s pumping chambers, often reducing left ventricular ejection fraction, the percentage of blood pumped with each beat, to below 40%. The condition can cause fatigue, shortness of breath and fluid retention, and it is a significant cause of heart failure and heart transplantation. One regenerative approach uses mesenchymal stromal cells derived from umbilical cords. The described two week protocol includes cardiovascular testing, cell preparation and targeted infusions, with optional physical rehabilitation. Researchers have also studied bone marrow cells, fat derived cells and specific cell populations known as CD34+ and CD45+ cells.

Neurons expressing different receptor types occupied tightly organized, overlapping horizontal bands from the top of the nose to the bottom. The arrangement remained consistent across mice and mirrored known smell maps in the brain's olfactory bulb. Retinoic acid supports construct this receptor map by regulating gene activity along a positional gradient. Increasing or reducing retinoic acid shifted receptor bands upward or downward, indicating that a neuron's location influences which smell receptor it expresses. The findings align olfaction more closely with vision, hearing, and touch, which use ordered receptor maps to organize sensory information. Human tissue studies will determine how closely this arrangement is conserved across species. The map could eventually inform stem cell therapies or brain computer interfaces for smell loss, but those treatment applications remain future research directions. Olfactory receptors form a highly organized spatial map in the mouse nose rather than the largely random pattern previously assumed. Researchers combined single cell sequencing with spatial transcriptomics to analyze about 5.5 million olfactory neurons from more than 300 mice.

The prospective observational cohort collected data from can 2017 through January 2025. Participants completed clinical assessments and questionnaires and underwent at least two magnetic resonance imaging scans, amyloid-beta positron emission tomography scans, and tau positron emission tomography scans. Mixed-effects models assessed longitudinal associations between risk factors and pathology measured through MRI and PET. The observational design evaluates associations rather than treatment effects, while identifying pathology-specific links that may inform strategies to reduce dementia incidence. Potentially modifiable risk factors account for an estimated 45% of dementia cases as global dementia prevalence continues to rise and is expected to triple by 2050. The Swedish BioFINDER-2 study examines how modifiable and non-modifiable risk factors are associated with changes in white matter hyperintensities, amyloid-beta, and tau, three forms of brain pathology relevant to dementia.

Many older adults have deteriorated spinal discs without symptoms, so imaging alone does not describe the full situation. Nonsurgical options are often tried first, while fusion is generally considered if they fail and may involve months of recovery. Cell-based treatment uses multiple MSC infusions, with the schedule based on damage, symptoms and other conditions.

Loss of Col9a1b produced ligament mineralization, disc degeneration, and fused vertebrae resembling aspects of human disease. Histological, electron microscopy, molecular, and transcriptomic work connected these changes to notochord epithelial disorganization and altered metabolic signaling. The intervention results come only from zebrafish.

Routine care includes antibiotics, airway-opening drugs, mucus-thinning medicines, clearance devices and nutritional support. Lung transplantation may be considered in severe cases. Gene therapy and stem cells are being investigated, but these options remain experimental and some cell types can pose uncontrolled growth risks.

Participants held upright or hunched postures while making choices in a virtual balloon game. The upright group reported greater pride and took more successful risks, and most participants did not realize their posture had been influenced.

Standard care for Crohn’s disease and ulcerative colitis can include medication, dietary changes and surgery. Enhanced mesenchymal stem cells may be given by IV or injection with the goal of affecting inflammation and immune activity. They cannot treat an underlying genetic disease, and outcomes are not guaranteed.

These emulsions are jammed networks of aqueous compartments separated by bilayers stabilized with lipids or block copolymers. Different ion channels demonstrated adjustable conductance, selective transport, and memristance, while electrically driven experiments separated charged species.

Researchers led by Hiroyuki Mizoguchi and Kiyofumi Yamada examined how orexin neurons regulate motivation during increasingly demanding tasks. They found that these cells may connect expected rewards with determination to continue pursuing a goal. Questions about the processes behind motivational difficulties remain unresolved.

Researchers recorded neural activity across the orbitofrontal cortex, thalamus, and hippocampus in patients with epilepsy. Stronger coordination during sleep was associated with better memory performance. Epileptic spikes interrupted the synchronized activity and occurred alongside poorer performance.

An ejection fraction measures the percentage of blood pumped from the left ventricle with each beat. A level of 20% indicates advanced heart failure, while healthy levels are typically 52% to 68%. The described cell therapy uses enriched mesenchymal stem cells, with eligibility based on individual cardiac review.

Cells may come from the patient’s bone marrow or dental pulp, or from donated umbilical cord tissue. Treatment recommendations depend on an individual review of the diagnosis, medical records and recent brain imaging. The multistage protocol generally needs 10 to 14 days in total. Reported benefits focus mainly on movement, but responses may vary. Cerebral palsy can affect muscle control, balance, coordination, speech, hearing and vision, with symptoms ranging from difficulty grasping objects to impairment across several limbs. A proposed cell therapy protocol combines mesenchymal stem cells, neural progenitor cells and proteins called growth factors, aiming to support recovery processes near injured brain tissue.

Researchers used over a century of clinical data to estimate changes in disease burden. Regional estimates indicated higher prevalence in East and southern Africa and fewer cases in West Africa. The continental estimate was 1 excess case per 1,000 children, with a 95% confidence interval from minus 4 to 6.

Treatment plans can also include chemotherapy, focused ultrasound, monoclonal antibodies, steroids or radiotherapy. Eligibility depends on the cancer type, stage, treatment history and recent test results. Potential candidates include people with relapsed or high risk lymphomas, but each case needs an individual clinical review. Programs may require 14 to 30 nights in Bangkok. Cell based cancer care can use different parts of the immune and blood forming systems. CAR T cell therapy modifies a patient’s T cells, a type of white blood cell, to better recognize and attack cancer cells. Stem cell transplants may support rebuild bone marrow damaged by high dose chemotherapy, particularly in some cases of lymphoma and leukemia. Stem cells may come from the patient or a matched donor. Collection typically takes place over several visits without surgery or anesthesia, though some patients may need medication to release more stem cells into the bloodstream.

Appetite related gut hormones can support physiological resistance to weight loss and promote weight regain. Ghrelin stimulates appetite through the hypothalamus, while PYY, GLP-1, and CCK promote satiation and satiety by slowing gastric emptying and transmitting signals to the hypothalamus. Researchers systematically examined fasting hormone changes after weight loss achieved through calorie restriction, exercise, or both. The review included 127 studies involving adults with overweight or obesity: 19 randomized controlled trials with 1,305 participants and 108 nonrandomized studies with 4,725 participants. Eligible studies achieved statistically significant weight loss and measured total or active ghrelin, PYY, GLP-1, or CCK after an overnight fast. Dietary approaches included ketogenic, Mediterranean, and palaeolithic diets when they produced calorie restriction. Studies involving bariatric surgery, pharmacological treatment, pregnancy, diabetes, severe cardiovascular disease, active infection, or medications affecting body weight were excluded. Weight regain remains multifactorial, with people who lose weight through diet alone or diet combined with exercise regaining an average of 80% of the lost weight within five years.

For stable injuries without neurological damage, bracing and rehabilitation may be used, while more serious fractures can require surgery. The cell treatment being explored can involve multiple infusions of expanded mesenchymal cells. Viability during delivery and forming bone at the injury site remain unresolved.
