Acute exposure to mobile phone and assessment of internal cerebral circulation in young healthy subjects : a transcranial Doppler study [PDF]

, 2012
International audienceThe rapid worldwide increase in the use of mobile phones raises questions about the possible adverse effects of RF fields emitted by these devices. The temporal lobe of brain is closest to the mobile phone.

Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Cerebrovascular ultrasonography: Technique and common pitfalls

Annals of Indian Academy of Neurology, 2013
Although the clinical features in some patients with cerebrovascular ischemia may be ill defined, majority of the patients present with focal neurological deficits caused by an arterial occlusion, and the clinical presentations are usually referable to ...

How breathing disrupts vision: hyperventilation‐induced hypocapnia impairs oculomotor responses in resting humans

The Journal of Physiology, EarlyView.
Abstract figure legend Hypocapnic hyperventilation reduced end‐tidal carbon dioxide partial pressure and middle cerebral artery mean velocity, and impaired oculomotor response by modulating visual fixation and anti‐saccadic control. Hyperventilation itself also impaired anti‐saccadic control.

Transcranial brain parenchyma sonography in movement disorders

Chinese Journal of Contemporary Neurology and Neurosurgery, 2012
The diagnosis and discrimination of movement disorders is very difficult in clinical medicine. We usually make a diagnosis according to symptoms and physical examination when the disease develops to a certain stage, but with few objective criteria ...

Overview of Diagnostic Ultrasound Safety

Journal of Ultrasound in Medicine, Volume 45, Issue 3, Page 487-496, March 2026.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Resting Cerebrovascular Haemodynamics and Dynamic Assessment of Cerebrovascular Function in Polycystic Ovary Syndrome

Clinical Endocrinology, Volume 104, Issue 3, Page 245-254, March 2026.
ABSTRACT Objective Despite an increased cerebrovascular disease risk, the impact of Polycystic Ovary Syndrome (PCOS) on cerebrovascular haemodynamics and function is unknown. This study characterised cerebrovascular haemodynamics and function in women with PCOS versus healthy controls. Design Case‐control study.

Economic Burden of Sickle Cell Disease: A Retrospective Study of Pediatric and Adult Individuals With Medicaid Coverage From 2016 to 2020

American Journal of Hematology, Volume 101, Issue 2, Page 269-280, February 2026.
ABSTRACT There is limited information regarding the contemporary real‐world clinical and financial burden of Medicaid enrollees with sickle cell disease (SCD) in the United States. Using the IBM MarketScan Medicaid database (7/2016–12/2020), individuals with ≥ 3 SCD diagnoses were matched 1:1 on age, gender, and race to individuals without SCD ...

Meningococcal Serogroup Y Meningitis Reveals Inborn Factor B Deficiency

European Journal of Immunology, Volume 56, Issue 2, February 2026.
We report a novel case of complete complement Factor B deficiency revealed by invasive meningococcal disease. Using combined functional and genetic analyses, we demonstrate that loss of Factor B abolishes alternative pathway activity despite detectable protein levels. These findings provide a mechanistic framework relevant to complement diagnostics and
