To investigate the pathological changes in the heart induced by pulmonary embolism, 20 autopsy cases of pulmonary embolism and 10 control cases of acute death from traumatic injury were examined. Adding to the routine hematoxylin-eosin (HE) staining, immunostaining with CD68 pan-macrophage marker was performed on the specimens obtained from both right and(More)
Acupuncture is one of the most popular complementary therapies in the world. Pneumothorax due to perforation of the lungs by needle insertion is one of the most common and serious complications of acupuncture treatment. Although there have been several case studies of pneumothorax induced by acupuncture, as far as we know there have been no reports on the(More)
Many studies suggest that mutans streptococci (MS), Lactobacillus (LB), and salivary buffering capacity are important risk factors for dental caries. However, target populations for most studies were children. In adult patients, the same risk factors affect the number of fillings or prostheses or secondary caries. It is therefore important to investigate(More)
Using 50 forensic blood samples, the latent membrane protein 2A (LMP-2A) gene of Epstein-Barr virus (EBV) DNA was amplified to find a geographic correlation among the EBV genotypes. EBV DNA was detected in nine samples. From a phylogenetic analysis using 18 reported sequences as a reference, six EBV subtypes (Ia, Ib, Ic IIa, IIb, and IIc) were found.(More)
Visual pigments in rod and cone photoreceptor cells of vertebrate retinas are highly diversified photoreceptive proteins that consist of a protein moiety opsin and a light-absorbing chromophore 11-cis-retinal. There are four types of cone visual pigments and a single type of rod visual pigment. The reaction process of the rod visual pigment, rhodopsin, has(More)
VA/VAL opsin is one of the four kinds of nonvisual opsins that are closely related to vertebrate visual pigments in the phylogenetic tree of opsins. Previous studies indicated that among these opsins, parapinopsin and pinopsin exhibit molecular properties similar to those of invertebrate bistable visual pigments and vertebrate visual pigments, respectively.(More)
There are no efficient methods to determine the geographic origin of unidentified cadavers. We showed earlier that the geographical distribution of the JC virus genotype detected from human kidneys indicates the host's geographical origin. As there are still cadavers from which we cannot detect the JC virus (JCV), we investigated whether the genotype of(More)
Bovine rhodopsin contains 11-cis-retinal as a light-absorbing chromophore that binds to a lysine residue of the apoprotein opsin via a protonated Schiff base linkage. Light isomerizes 11-cis-retinal into the all-trans form, which eventually leads to the formation of an enzymatically active state, metarhodopsin II (MII). It is widely believed that MII forms(More)
