Simultaneous occurrence of intracerebral hemorrhage (ICH) in different arterial territories is an uncommon event. We report on two cases of multiple spontaneous simultaneous ICH for which we could find no specific cause. A 73-year-old man, with no related medical history, was admitted to the hospital with simultaneous bithalamic ICH, and subsequently died of recurrent pneumonia. Second patient was a 60-year-old man who presented with simultaneous ICH in the pons and thalamus; he died of recurrent bleeding. We review the possible pathological mechanisms, clinical and radiologic features of simultaneous multiple ICH.

Beyond the light reflex, the pupil responds to various high-level cognitive processes. Multiple statistical regularities of stimuli have been found to modulate the pupillary response. However, most studies have used auditory or visual temporal sequences as stimuli, and it is unknown whether the pupil size is modulated by statistical regularity in the spatial arrangement of stimuli.

Pathological fractures after jaw cyst surgery are rare clinically but are a serious complication. Once a pathological fracture occurs, treatment time and economic costs increase, and doctors face difficulty in handling it. This article reports a case of a patient with mandibular pathological fractures after multiple odontogenic keratocyst surgery of the jaw.

Amyloidosis is characterized by the extracellular deposition of insoluble protein fibrils that cause cellular damage and dysfunction in organs and tissues. Multiple types of amyloidosis and their causative precursor proteins have been identified in humans and animals. In toxicological studies, a high incidence of spontaneous amyloidosis has been reported in CD-1 mice; however, the precursor protein responsible remains unclear.

Blink-related oscillations (BROs) are newly discovered neurophysiological brainwave responses associated with spontaneous blinking, and represent environmental monitoring and awareness processes as the brain evaluates new visual information appearing after eye re-opening. BRO responses have been demonstrated in healthy young adults across multiple task states and are modulated by both task and environmental factors, but little is known about this phenomenon in aging. To address this, we undertook the first large-scale evaluation of BRO responses in healthy aging using the Cambridge Centre for Aging and Neuroscience (Cam-CAN) repository, which contains magnetoencephalography (MEG) data from a large sample ( = 457) of healthy adults across a broad age range (18-88) during the performance of a simple target detection task.

Here a bioengineered platform is introduced to investigate adverse effects of environmental materials on the human cornea. Using primary cells, this system is capable of reproducing the differentiated corneal epithelium and its underlying stroma in the human eye, which can then be treated with externally applied solid, liquid, or gaseous substances in a controlled manner and under physiologically relevant conditions. The proof-of-principle of how this system can be used to simulate human ocular exposure to different classes of environmental toxicants for direct visualization and quantitative analysis of their potential to induce acute corneal injury and inflammation is demonstrated.
