Homozygous Mutation in the FANCD2 Gene Observed in a Saudi Male Infant with Severe Ambiguous Genitalia.

Case Rep Endocrinol 2021 16;2021:6686312. Epub 2021 Jul 16.

Department of Pediatrics, King Abdulaziz Hospital, Ministry of National Guard-Health Affairs, Al-Ahasa, Saudi Arabia.

Fanconi anemia (FA) is a rare autosomal recessive inherited disease caused by gene mutations that are primarily involved in the response to or repair of DNA damage. FA characterizes by multiple congenital abnormalities and malformations including growth retardation, renal agenesis, absence of radial bones and thumbs as well, progressive bone marrow failure, irregular skin pigmentation patterns, and increased susceptibility to cancer. FANCD2 gene mutation is believed to be one of the causative mutations in Fanconi anemia, and despite many case reports that link the FANC gene mutation to multiple congenital anomalies and disease, there is no case report found to link it with genitalia abnormalities.

Airwave oscillometry to measure lung function in children with Down syndrome.

Pediatr Res 2021 Jul 29. Epub 2021 Jul 29.

Department of Pediatrics, University of Colorado, Aurora, CO, USA.

Background: Children with Down syndrome are at risk for significant pulmonary co-morbidities, including recurrent respiratory infections, dysphagia, obstructive sleep apnea, and pulmonary vascular disease. Because the gold standard metric of lung function, spirometry, may not be feasible in children with intellectual disabilities, we sought to assess the feasibility of both airwave oscillometry and spirometry in children with Down syndrome.

Combined treatment with C16 peptide and angiopoietin-1 confers neuroprotection and reduces inflammation in 3-nitropropionic acid-induced dystonia mice.

Aging (Albany NY) 2021 Jul 29;13(undefined). Epub 2021 Jul 29.

Institute of Anatomy and Cell Biology and Sir Run Run Shaw Hospital, Medical College, Zhejiang University, Hangzhou, China.

Dystonia is a disorder associated with abnormalities in many brain regions including the basal ganglia and cerebellum. The toxin 3-Nitropropionic acid (3-NP) can induce neuropathologies in the mice striatum and nigra substance, including excitotoxicity, neuroinflammation, and extensive neuronal atrophy, characterized by progressive motor dysfunction, dystonia, and memory loss, mimicking those observed in humans. We established a mouse model of dystonia by administering 3-NP. Read More

Clonazepam attenuates neurobehavioral abnormalities in offspring exposed to maternal immune activation by enhancing GABAergic neurotransmission.

Biochem Pharmacol 2021 Jul 26:114711. Epub 2021 Jul 26.

State Key Laboratory of Quality Research in Chinese Medicine and Institute of Chinese Medical Sciences, University of Macau, Macao 999078, China. Electronic address:

Ample evidence indicates that maternal immune activation (MIA) during gestation is linked to an increased risk for neurodevelopmental and psychiatric disorders, such as autism spectrum disorder (ASD), anxiety and depression, in offspring. However, the underlying mechanism for such a link remains largely elusive. Here, we performed RNA sequencing (RNA-seq) to examine the transcriptional profiles changes in mice in response to MIA and identified that the expression of Scn1a gene, encoding the pore-forming α-subunit of the brain voltage-gated sodium channel type-1 (Na1.

Improving the predictive potential of diffusion MRI in schizophrenia using normative models-Towards subject-level classification.

Hum Brain Mapp 2021 Jul 29. Epub 2021 Jul 29.

Department of Psychiatry, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Diffusion MRI studies consistently report group differences in white matter between individuals diagnosed with schizophrenia and healthy controls. Nevertheless, the abnormalities found at the group-level are often not observed at the individual level. Among the different approaches aiming to study white matter abnormalities at the subject level, normative modeling analysis takes a step towards subject-level predictions by identifying affected brain locations in individual subjects based on extreme deviations from a normative range.

Jay Pravda

World J Crit Care Med 2021 Jul 9;10(4):66-80. Epub 2021 Jul 9.

Inflammatory Disease Research Centre, Therashock LLC, Palm Beach Gardens, FL 33410, United States.

Sepsis can develop during the body's response to a critical illness leading to multiple organ failure, irreversible shock, and death. Sepsis has been vexing health care providers for centuries due to its insidious onset, generalized metabolic dysfunction, and lack of specific therapy. A common factor underlying sepsis is the characteristic hypermetabolic response as the body ramps up every physiological system in its fight against the underlying critical illness. Read More
