Lipidome Profiling of Phosphorus Deficiency-Tolerant Rice Cultivars Reveals Remodeling of Membrane Lipids as a Mechanism of Low P Tolerance.

Plants have evolved various mechanisms for low P tolerance, one of which is changing their membrane lipid composition by remodeling phospholipids with non-phospholipids. The objective of this study was to investigate the remodeling of membrane lipids among rice cultivars under P deficiency. Rice ( L.

A case of acinar cell carcinoma of the pancreas that formed extensive tumor thrombus of the portal vein.

A 58-year-old man was admitted to our hospital because of anorexia and back pain. He had been previously diagnosed with chronic pancreatitis with blood thrombus of the splenic vein at another hospital. Abdominal ultrasonography and computed tomography revealed a large mass in the body and tail of the pancreas, which directly invaded the stomach and the spleen.

Immunohistochemical localization of gonadotropin-associated peptide (GAP) in the human hypothalamus.

GAP was immunohistochemically localized for the first time in the human hypothalamus. GAP-immunoreactivity was present in the cytoplasm of neuronal cells in the arcuate nucleus. GAP-immunoreactive nerve fibers were also present in the primary plexus around capillaries in the infundibular region.

Precancerous lesions of the gallbladder mucosa.

To elucidate the morphological characteristics and the incidence of precancerous lesions of the gallbladder, 200 gallbladders removed for presumed benign diseases were examined histopathologically. Dysplastic epithelia with distinct cellular and structural atypia were graded into either mild or moderate to severe degree. Twenty-nine (14.

Sinus histiocytosis with massive lymphadenopathy. A histogenic analysis of histiocytes found in the fourth Japanese case.

The present paper deals with immunohistochemical and ultrastructural study of the lymph nodes of sinus histiocytosis with massive lymphadenopathy (Rosai and Dorfman, SHML) of a 12-year-old Japanese boy. This is the fourth case in Japan. Osseous manifestation was also found in the bilateral ulnae.

Giant hyperplasiogenous polyp of the stomach simulating malignant polyp.

A surgical case of giant hyperplasiogenous polyp of the stomach with unusual radiological and pathological findings is presented. Radiological and endoscopical examinations revealed characteristic papillary (villous) features simulating either true adenoma or malignant polyp of the antrum. Complete serial sections from the resected stomach disclosed no malignant area anywhere in and out of the polyp.

Pulmonary hypertension associated with liver cirrhosis and hepatitis-B antigenemia.

An autopsy case of pulmonary hypertension in a 29-year-old Japanese female with macronodular, posthepatic liver cirrhosis and hepatitis-B antigenemia was presented. No recognizable known cardio-pulmonary disease or portal thrombosis was obtained. Hepatitis-B antigen was demonstrated in the cirrhotic hepatocytes by a specific peroxidase antiperoxidase method.

Dysplasia and carcinoma in situ of the exocrine pancreas.

To clarify the morphological aspect of precancerous and related lesions of the exocrine pancreas, histological studies were carried out according to a systematized protocol. The pancreas, its head, body and tail including the papilla and adjacent duodenal mucosa and the distal common bile duct from 206 unselective autopsy cases, excluding those of pancreatic carcinoma, were systematically examined. Histological grading of dysplasia was performed based on structural (SAT) and cellular (CAT) atypia which were evaluated by coding 0, 1, 2, and 3.

Autopsy findings in a case of acute paraquat poisoning with extensive cerebral purpura.

An autopsy case of paraquat poisoning in an adult male died on the 6th day of intoxication was presented. Histological and electron microscopic observations demonstrated interstitial pneumonia with distinct interstitial fibrosis and the initial stage of alveolar fibrosis with coexisting edema and hyaline membrane formation. Striking hemorrhagic leukoencephalopathy, i.

Evaluation of esophageal dysplasia by cytofluorometric analysis.

In order to grade objectively and characterize dysplastic and precancerous esophageal epithelium its DNA content was measured by cytofluormetric methods and compared to normal and cancerous esophageal epithelium. This yielded the following results. With transition of the esophageal eipthelium from mild dysplasia to severe dysplasia and finally to in situ carcinoma, Feulgen-DNA values showed patterns characteristic of a tetraploid population.

Epithelial dysplasia in cancerous and noncancerous esophagi.

Subserial examinations of the noncancerous esophagus from 86 autopsy materials (male 47, female 39) in Kagoshima Prefecture revealed epithelial dysplasia in 54 instances (63%); 32 males (68%) and 22 females (57%). Higher grades of dysplasia were shown in 17 males (36%) and 3 females (8%). Histologically a formation of the rete ridge-like elongation of basal epithelium was characteristically conspicuous in these materials.

Comparative studies on dysplasia of esophageal epithelium in four prefectures of Japan (Miyagi, Nara, Wakayama and Aomori) with reference to risk of carcinoma.

Distal two-thirds of the esophagus without macroscopically detectable malignant lesions from a total of 248 autopsy cases were examined for epithelial dysplasia on histological sections from serial blocks. The autopsy specimens had been obtained from Miyagi. Nara and Wakayama prefectures known for high incidence of esophageal carcinoma in Japan, and Aomori prefecture where the incidence of the disease is low.
