The title compound, C(18)H(16)O(2), was prepared by reduction of 2-(5,6,7,8-tetra-hydro-2-naphtho-yl)benzoic acid with zinc dust. The benzene ring in the tetra-hydro-naphthyl substituent is nearly perpendicular to the plane of the isobenzofuran-1(3H)-one ring [87.15 (4)°]. The cyclo-hexane unit has a half-chair conformation in which two methylene groups in the tetra-methyl-ene bridge are disordered over two positions; the site-occupancy factors are 0.838 (4) and 0.162 (4). The crystal structure exhibits alternating isobenzofuran-1(3H)-one and tetra-hydro-naphthalene layers.

Therapeutic reduction of neurocan in murine intracerebral hemorrhage lesions promotes oligodendrogenesis and functional recovery.
J Neuroinflammation
January 2025
Department of Cerebrovascular Diseases, The Second Affiliated Hospital of Zhengzhou University, 2 Jingba Road, Zhengzhou, Henan, China.
Background: Intracerebral hemorrhage (ICH) causes prominent deposition of extracellular matrix molecules, particularly the chondroitin sulphate proteoglycan (CSPG) member neurocan. In tissue culture, neurocan impedes the properties of oligodendrocytes. Whether therapeutic reduction of neurocan promotes oligodendrogenesis and functional recovery in ICH is unknown.

Purpose: To identify the PASS and SCB thresholds for hip arthroscopy and provide guidance on how to choose among the thresholds.
Methods: A systematic review of literature was conducted in PubMed and MEDLINE databases in August 2024 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Studies with Level I to IV evidence that defined SCB or PASS thresholds for PROs for hip arthroscopy in the setting of intra-articular pathology were included.

Department of Obstetrics and Gynaecology, Faculty of Health Sciences, University of Pretoria, Pretoria, South Africa.
Background: Female sterilization, a safe, permanent method of contraception that blocks the fallopian tubes, has been in use since the 19th century. The procedure necessitates informed consent, a critical step that has been marred by reports of forced sterilization since World War II. These incidents often stem from inadequate consent processes where ethical principles are overlooked or deliberately flouted.
