Cranial and Cerebral Anatomic Key Points for Neurosurgery: A New Educational Insight.
Oper Neurosurg (Hagerstown)
January 2022
Department of Anatomy, University of Lyon 1, Lyon, France.
Background: The anatomy of both the skull and the brain offers many landmarks that could lead surgery. Cranial "craniometric" key points were described many years ago, and then, cerebral key points-along sulci and gyri-were detailed more recently for microneurosurgical approaches that can reach deep structures while sparing the brain. Nonetheless, this anatomic knowledge is progressively competed by new digital devices, such as imaging guidance systems, although they can be misleading.

The rational delimitation of urban development boundary plays an important role in guiding the orderly growth of urban space and ensure proper environment health of urban space. In this study, we evaluated the ecological sensitivity of Nanchang City from four aspects (soil erosion, habitat, geological disaster and water resource) and simulated urban expansion in 2020 based on CA-Markov and land use data in 2000, 2010 and 2015. Spatial decision-making analysis of the two aspects was carried out in combination to the future development of the study area.

Department of Dermatology, the 4th Affiliated Hospital of HeBei Medical University, No.12 JianKang Road, ShiJiaZhuang 050011, P.R. China.
The increased use of novel and powerful immunosuppressive drugs in kidney diseases may concomitantly expose the patients to higher risk of opportunistic infections, some of which still remain underdiagnosed thus mishandled. As such, we recently had a less prepared encounter of pulmonary nocardial infection in an ANCA-associated renal vasculitis patient under steroid therapy. Despite the use of broad-spectrum antimicrobials including micafungin, the infection was still unbridled and eventually culminated in lethal brain abscess.

June 2019
Department of Chemical Engineering , Monash University, Wellington Road , Clayton , Victoria 3800 , Australia.
The renewed interest in plasma desiccation patterns focuses on the potential of these patterns to be developed into a platform of low-cost and facile diagnostic methods to interpret health conditions of donors. During desiccation, several physical mechanisms are simultaneously acting on the plasma sessile drop; these include material redistribution, buildup/release of local internal stresses, protein aggregation, and salt crystallization. After desiccation, cracking patterns and "superimposed" crystal-like patterns are formed.

Department of Medicine, Division of Hematology, Stanford University School of Medicine, Stanford, CA 94305, USA. Electronic address:
The intestinal epithelium is a rapidly renewing cellular compartment. This constant regeneration is a hallmark of intestinal homeostasis and requires a tightly regulated balance between intestinal stem cell (ISC) proliferation and differentiation. Since intestinal epithelial cells directly contact pathogenic environmental factors that continuously challenge their integrity, ISCs must also actively divide to facilitate regeneration and repair.
