Primary microglia dysfunction or microgliopathy: A cause of dementias and other neurological or psychiatric disorders.

Neuroscience 2022 Jun 24. Epub 2022 Jun 24.

Basic Research and Advanced Investigations in Neurosciences (BRAIN), Universidade Federal do Rio Grande do Sul, Brazil.

Microglia are unique cells in the central nervous system (CNS), being considered a sub-type of CNS macrophage. These cells monitor nearby micro-regions, having roles that far exceed immunological and scavengering functions, being fundamental for developing, protecting and maintaining the integrity of grey and white matter. Microglia might become dysfunctional, causing abnormal CNS functioning early or late in the life of patients, leading to neurologic or psychiatric disorders and premature death in some patients.

J Craniofac Surg 2022 Jun 27. Epub 2022 Jun 27.

Department of Plastic and Reconstructive Surgery, Wake Forest Baptist Health, Winston-Salem, NC.

Abstract: The posterior intraoccipital synchondrosis (PIOS) is a cartilaginous division separating the exoccipital and supraoccipital bones, allowing for flexibility of the cranial base at birth and which later ossifies in adolescence. The authors report a case of right PIOS synostosis that resembled right lambdoid synostosis, with left occipital bossing in a healthy, six-month-old female with an unremarkable birth history and no antecedent trauma. An initial referral was made from the pediatrician to oncology because of a concern over the presence and growth of a possible mass at the left occiput. Read More

A function for ataxia telangiectasia and Rad3-related (ATR) kinase in cytokinetic abscission.

iScience 2022 Jul 6;25(7):104536. Epub 2022 Jun 6.

Genome Stability Laboratory, Centre for Chromosome Biology, Biochemistry & School of Natural Sciences, National University of Ireland Galway, Galway, Ireland.

Abscission, the final stage of cytokinesis, occurs when the cytoplasmic canal connecting two emerging daughter cells is severed either side of a large proteinaceous structure, the midbody. Here, we expand the functions of ATR to include a cell-cycle-specific role in abscission, which is required for genome stability. All previously characterized roles for ATR depend upon its recruitment to replication protein A (RPA)-coated single-stranded DNA (ssDNA). Read More

Authors:
Peter Petros

Neurourol Urodyn 2022 Jun 26. Epub 2022 Jun 26.

Mechanical and biomechanical engineering, University of Western Australia School of Engineering and Mathematical Sciences, Perth, Western Australia, Australia.

SUBJECT OF THE DEBATE: "Urethral failure is a critical factor in female urinary incontinence Now what?" The CASE FOR by Hokanson, DeLancey pinpointed inadequacy of bladder causation for urgency urinary incontinence (UUI) and poor urethral support for stress urinary incontinence (SUI) as responsible for long-standing lack of progress in incontinence science. They proposed "Urethral failure" as causation for SUI and UUI. The CASE AGAINST, by Peter Petros agrees "abnormal detrusor function as cause for (UUI) is a failed concept, and SUI surgery results are sometimes suboptimal, but rejects "urethral failure" as cause for UUI and SUI.

Common genetic variation in KATNAL1 non-coding regions is involved in the susceptibility to severe phenotypes of male infertility.

Andrology 2022 Jun 25. Epub 2022 Jun 25.

Instituto de Investigación Biosanitaria ibs.GRANADA, Granada, Spain.

Background: Previous studies in animal models evidenced that genetic mutations of KATNAL1, resulting in dysfunction of its encoded protein, lead to male infertility through disruption of microtubule remodelling and premature germ cell exfoliation. Subsequent studies in humans also suggested a possible role of KATNAL1 single-nucleotide polymorphisms (SNPs) in the development of male infertility as a consequence of severe spermatogenic failure (SpF).

Objectives: The main objective of the present study is to evaluate the effect of the common genetic variation of KATNAL1 in a large and phenotypically well-characterized cohort of infertile men due to SpF. Read More
