Complement activation and lung injury in Japanese patients with COVID-19: a prospective observational study.

Background The production of inflammatory cytokines is reportedly increased in patients with coronavirus disease 2019 (COVID-19), causing the migration of neutrophils and monocytes to lung tissues. This disrupts the air-blood barrier by damaging the bronchial epithelial and vascular endothelial cells. As multiorgan dysfunction in sepsis is considered to be partly caused by complement activation, which can cause lung injury in patients with COVID-19.

seed oil combined with leaf powder attenuates age-related cognitive decline by reducing serum triglyceride and glucose levels in healthy elderly Japanese individuals: a possible supplement for brain health.

We have shown that extract improves learning and memory in a senescence-accelerated mouse model, and that α-linolenic acid (ALA)-rich seed oil (PO) improves brain function in healthy Japanese adults and elderly individuals. Herein, we present a 12-month, randomised, double-blind, parallel-armed intervention trial examining the effects of PO supplementation alone or in combination with leaf powder on brain function in healthy elderly Japanese individuals. Participants were randomly divided into two groups: the PO group received 1.

Complement Activation in Patients With Heat-Related Illnesses: Soluble CD59 Is a Novel Biomarker Indicating Severity of Heat-Related Illnesses.

Objectives: Although multiple organ dysfunction syndrome (MODS) is the main cause of death in patients with heat-related illnesses, its underlying pathophysiological mechanism remains elusive. Complement activation is considered one of the main causes of MODS in patients with sepsis and trauma. Considering the pathophysiological similarity of heat related-illnesses with sepsis and trauma, the complement system might be activated in patients with heat-related illnesses as well.

seed oil in combination with nobiletin-rich ponkan powder enhances cognitive function in healthy elderly Japanese individuals: a possible supplement for brain health in the elderly.

() seed oil (PO), rich in α-linolenic acid (ALA), can improve cognitive function in healthy elderly Japanese people. Here, supplements containing either PO alone or PO with nobiletin-rich air-dried immature ponkan powder were examined for their effects on cognitive function in 49 healthy elderly Japanese individuals. Patients were enrolled in a 12-month randomized, double-blind, parallel-armed study.

Influence of Ultra-High Hydrostatic Pressurizing Brown Rice on Cognitive Functions and Mental Health of Elderly Japanese Individuals: A 2-Year Randomized and Controlled Trial.

Brown rice contains many ingredients that might protect against cognitive decline and Alzheimer's disease. However, brown rice is very hard, difficult to cook, and is poorly digested; thus, it is difficult to eat long-term. To solve these problems, ultra-high hydrostatic pressurizing brown rice (UHHPBR) was prepared.

Fluorescence imaging of ATP in neutrophils from patients with sepsis using organelle-localizable fluorescent chemosensors.

Background: The activation of polymorphonuclear neutrophils (PMNs) plays an important role in sepsis. Previously, we showed that ATP release and feedback via ATP receptors are essential for PMN activation; however, the dynamics remain poorly understood. Two new fluorescent chemosensors, PMAP-1 and MitoAP-1, were developed to detect ATP in the plasma membrane and mitochondria of living cells, respectively.

Long-term survival after two surgical resections of peritoneal metastases from hepatocellular carcinoma with an interval of 4 years.

We propose that surgical resections of peritoneal metastases arising from hepatocellular carcinoma are an option for selected patients with controlled HCC in the liver, and without metastases in other organs, when the complete removal of such metastases can be achieved, especially in the case of patients with normal liver function.

Leukocyte deformability is a novel biomarker to reflect sepsis-induced disseminated intravascular coagulation.

Aim: Sepsis-induced disseminated intravascular coagulopathy is associated with a high mortality rate. The function and deformability of polymorphonuclear leukocytes change in patients with sepsis. The goal of this study was to characterize the changes in polymorphonuclear leukocyte deformability in patients with sepsis-induced disseminated intravascular coagulopathy and to evaluate the relationship between the severity of disseminated intravascular coagulopathy and the deformability of polymorphonuclear leukocytes.

Clinical and pathological evaluation of hypertensive emergency-related nephropathy.

Objective: The prognosis of patients with hypertensive emergencies has recently improved dramatically owing to the development of effective antihypertensive therapy. We examined the histological and clinical features of patients with hypertensive emergency-related nephropathy.

Methods: Twelve patients (11 men and one woman) were diagnosed as having hypertensive emergencies with acute renal failure according to the Joint National Committee-7 classification of blood pressure for adults and underwent renal biopsies at our hospital between 1995 and 2008.

Post-stroke apathy and hypoperfusion in basal ganglia: SPECT study.

Background: Although apathy has been reported as one of the neuropsychiatric symptoms following stroke, there are few studies on regional cerebral blood flow (rCBF) in stroke patients with apathy. The present study compared rCBF between apathetic and non-apathetic patients after stroke.

Methods: We recruited 102 patients with cerebral infarction within 1 month after stroke and performed neuropsychiatric assessments that included the apathy scale.
