Direct observations of energy transfer from resonant electrons to whistler-mode waves in magnetosheath of Earth.

Electromagnetic whistler-mode waves in space plasmas play critical roles in collisionless energy transfer between the electrons and the electromagnetic field. Although resonant interactions have been considered as the likely generation process of the waves, observational identification has been extremely difficult due to the short time scale of resonant electron dynamics. Here we show strong nongyrotropy, which rotate with the wave, of cyclotron resonant electrons as direct evidence for the locally ongoing secular energy transfer from the resonant electrons to the whistler-mode waves using ultra-high temporal resolution data obtained by NASA's Magnetospheric Multiscale (MMS) mission in the magnetosheath. The nongyrotropic electrons carry a resonant current, which is the energy source of the wave as predicted by the nonlinear wave growth theory. This result proves the nonlinear wave growth theory, and furthermore demonstrates that the degree of nongyrotropy, which cannot be predicted even by that nonlinear theory, can be studied by observations.

The advanced lung cancer inflammation index predicts outcomes in patients with Crohn's disease after surgical resection.

AIM: Precise biomarkers for predicting prognosis could help to identify high-risk Crohn's disease (CD) patients to facilitate better follow-up during the postoperative course. In this study, the primary aim is the identification of the most reliable nutrition marker that predicts surgical relapse in CD patients. METHOD: We first evaluated the predictive value of various nutrition markers for postoperative surgical relapse in CD patients and identified the advanced lung cancer inflammation index (ALI) as a promising biomarker. Then, we assessed the clinical significance of preoperative ALI in CD patients using two cohorts. RESULTS: Preoperative ALI showed the highest correlation with reoperation rate compared with other nutritional parameters in CD patients receiving surgical resection (sensitivity 53%, specificity 86%, area under the curve 0.71). Lower levels of preoperative ALI were significantly correlated with the presence of perianal disease. A lower level of preoperative ALI was an independent prognostic factor for reoperation rate after an intestinal resection (hazard ratio 3.37, 95% CI 1.38-10.12, P = 0.006), and the prognostic impact of preoperative ALI was successfully validated in an independent cohort using the same cut-off value. CONCLUSION: Preoperative ALI might be useful for postoperative management of CD patients.

Predictors of Cerebral Aneurysm Rupture after Coil Embolization: Single-Center Experience with Recanalized Aneurysms.

BACKGROUND AND PURPOSE: Recanalization after coil embolization is widely studied. However, there are limited data on how recanalized aneurysms rupture. Herein, we describe our experience with the rupture of recanalized aneurysms and discuss the type of recanalized aneurysms at greatest rupture risk. MATERIALS AND METHODS: A total of 426 unruptured aneurysms and 169 ruptured aneurysms underwent coil embolization in our institution between January 2009 and December 2017. Recanalization occurred in 38 (8.9%) of 426 unruptured aneurysms (unruptured group) and 37 (21.9%) of 169 ruptured aneurysms (ruptured group). The Modified Raymond-Roy classification on DSA was used to categorize the recanalization type. Follow-up DSA was scheduled until 6 months after treatment, and follow-up MRA was scheduled yearly. If recanalization was suspected on MRA, DSA was performed. RESULTS: In the unruptured group, the median follow-up term was 74.0 months. Retreatment for recanalization was performed in 18 aneurysms. Four of 20 untreated recanalized aneurysms (0.94% of total coiled aneurysms) ruptured. In untreated recanalized aneurysms, class IIIb aneurysms ruptured significantly more frequently than class II and IIIa (P = .025). In the ruptured group, the median follow-up term was 28.0 months. Retreatment for recanalization was performed in 16 aneurysms. Four of 21 untreated recanalized aneurysms (2.37% of total coiled aneurysms) ruptured. Class IIIb aneurysms ruptured significantly more frequently than class II and IIIa (P = .02). CONCLUSIONS: The types of recanalization after coil embolization may be predictors of rupture. Coiled aneurysms with class IIIb recanalization should undergo early retreatment because of an increased rupture risk.

Nonlinear saturation of cyclotron maser instability associated with energetic ring-beam electrons.

We study the cyclotron maser instability (CMI) driven by an energetic ring-beam distribution by a particle simulation to explain possible generation mechanisms of intense radiation phenomena observed in space. The main objective is to understand the nonlinear processes that control saturation of the emission process. Our study reveals new issues that have been overlooked in past literature. It is found that electrostatic wave modes excited by the electron beam instability compete with the electromagnetic waves excited by the CMI. Nonlinear effects of these electrostatic modes tend to redistribute the energy of the energetic electrons and make the physics more complicated. The CMI can be much less effective in a realistic case than it is anticipated theoretically.

Palladium adsorbing properties of UV-curable chitosan derivatives and surface analysis of chitosan-containing paint.

The results of X-ray photoelectron spectroscopy (XPS) analyses indicated that palladium chloride was adsorbed on a plastic surface coated with a chitosan-containing paint (C-Paint), and was completely reduced to Pd(0) after reduction with dimethylamine-borane. To improve the stability and hardening properties of C-Paint, UV-curable chitosan derivatives, such as N-[3-methoxy-4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]methylated chitosan and N-(3-methoxy-4-methacryloyloxyphenyl)methylated chitosan, were synthesized. The derivatives showed better affinity for organic solvents. After UV irradiation for 20s, an acidic solution of these derivatives was transformed to a gel, and the dried films exhibited good palladium(II) adsorption at pH 1.1.

Conjugated linoleic acid accumulation via 10-hydroxy-12-octadecaenoic acid during microaerobic transformation of linoleic acid by Lactobacillus acidophilus.

Specific isomers of conjugated linoleic acid (CLA), a fatty acid with potentially beneficial physiological and anticarcinogenic effects, were efficiently produced from linoleic acid by washed cells of Lactobacillus acidophilus AKU 1137 under microaerobic conditions, and the metabolic pathway of CLA production from linoleic acid is explained for the first time. The CLA isomers produced were identified as cis-9, trans-11- or trans-9, cis-11-octadecadienoic acid and trans-9, trans-11-octadecadienoic acid. Preceding the production of CLA, hydroxy fatty acids identified as 10-hydroxy-cis-12-octadecaenoic acid and 10-hydroxy-trans-12-octadecaenoic acid had accumulated. The isolated 10-hydroxy-cis-12-octadecaenoic acid was transformed into CLA during incubation with washed cells of L. acidophilus, suggesting that this hydroxy fatty acid is one of the intermediates of CLA production from linoleic acid. The washed cells of L. acidophilus producing high levels of CLA were obtained by cultivation in a medium containing linoleic acid, indicating that the enzyme system for CLA production is induced by linoleic acid. After 4 days of reaction with these washed cells, more than 95% of the added linoleic acid (5 mg/ml) was transformed into CLA, and the CLA content in total fatty acids recovered exceeded 80% (wt/wt). Almost all of the CLA produced was in the cells or was associated with the cells as free fatty acid.

Development of a novel enzyme-linked immunosorbent assay for blood and urinary eosinophil-derived neurotoxin: a preliminary study in patients with bronchial asthma.

BACKGROUND: Eosinophil-derived neurotoxin (EDN), also called eosinophil protein X (EPX), has been suggested to be a useful marker of eosinophilic inflammation. However, no commercial enzyme-linked immunosorbent assay (ELISA) kit for EDN is available yet. METHODS: EDN was purified from pooled urine from healthy male volunteers. Polyclonal and monoclonal anti-EDN antibodies were subsequently raised, and a sandwich ELISA for EDN was established. EDN levels in serum, plasma and urine from asymptomatic patients with bronchial asthma were measured by the ELISA method. Some of the blood samples were also measured by a commercial radioimmunoassay (RIA) kit. RESULTS: The ELISA method detected human EDN with a minimum detection limit of less than 0.62 ng/ml and did not cross-react with other eosinophil granule cationic proteins including eosinophil cationic protein. The intra- and interassay coefficients of variation of the ELISA method ranged from 2.6 to 3.6% and from 6.5 to 9.4%, respectively. Good linearity was observed with serially diluted different samples, and the recoveries of the purified EDN added to serum samples ranged from 85 to 110%. Median EDN concentrations in serum (36.9 vs. 19.1 ng/ml), plasma (23.0 vs. 14.5 ng/ml) and urine (118.2 vs. 72.1 microg/mmol Cr) were significantly raised in asymptomatic asthmatic patients compared with healthy control subjects. EDN levels in serum, plasma and urine from the patients significantly correlated with the number of peripheral blood eosinophils, but not total serum IgE levels. A significant relationship between EDN values measured by the EPX-RIA kit and the EDN-ELISA method was observed. CONCLUSIONS: We have developed a novel efficient ELISA method to specifically measure blood and urinary EDN, which may be useful to study the role of eosinophils in allergic diseases including bronchial asthma.

Immunocytochemical localization of taurine in the fish retina under light and dark adaptations.

Previously we have observed the lack of immunoreactivity of taurine in the rod outer segments from light-adapted fish, such as the ayu Plecoglossus altivelis and lefteye flounder Paralichthys olivaceus. This finding prompted us to investigate if there is a difference in the immunocytochemical localization of taurine in the rod outer segments between the dark- and light-adapted states. In the retinas of the glass eel Anguilla japonica and the young goldfish Carassius auratus, extremely intense immunostaining was found in the cone outer segments, rod inner segments, photoreceptor supranuclear region and outer plexiform layer. The rod outer segments were not immunostained in the light-adapted state, while they were intensely immunostained in the dark-adapted state. Consequently, it was suggested that the lack of immunoreactivity in the rod outer segment may depend on light stimulation. In addition, the conspicuous immunocytochemical localization of taurine was discussed with the possible functional roles for taurine in the fish retina.

Gastric cancer with sarcoid reactions in the regional lymph nodes, the stomach wall, and the splenic parenchyma: report of a case.

A 66-year-old man was referred to our institute for investigation of heartburn and epigastralgia. Endoscopic examination demonstrated a type 4' gastric cancer which occupied the whole stomach. At laparotomy, multiple small nodules were found in the spleen which were diagnosed as metastases of the gastric cancer. Thus, total gastrectomy with distal pancreatectomy, splenectomy, cholecystectomy, and left adrenalectomy, combined with D4 lymph node dissection, was performed. Microscopic examination of the tumor revealed tubular and mucinous adenocarcinoma which invaded the muscularis propria. Sarcoid reactions were observed in the submucosa adjacent to the carcinoma tissue. Only one lymph node from station no. 8a demonstrated tumor metastasis, while those from station nos. 1, 2, 7, 8, 9, 10, 11, 13, and 16 revealed sarcoid reactions without tumor metastases. Subsequently, the multiple small nodules that had been presumed to be splenic metastases at laparotomy were found to be sarcoid reactions similar to those seen in the submucosa and regional lymph nodes. Since no skin or ocular lesions indicative of systemic sarcoidosis were seen in this patient, a diagnosis of advanced gastric cancer associated with sarcoid reactions was established. To our knowledge, there have been no previous reports regarding an association between sarcoid reactions in the spleen and gastric cancer.

Immunocytochemical localization of taurine in the developing retina of the lefteye flounder Paralichthys olivaceus.

Light microscopic immunolocalization of taurine, a sulfur-containing free amino acid, was investigated in the developing retina of a lefteye flounder, Paralichthys olivaceus, which exhibits metamorphic changes with rod cell addition for 3-5 weeks after hatching. This immunocytochemical study of the developing retina revealed: 1) From 3 to 13 days after hatching, intense immunostaining was shifted from the surroundings of neural cells to the neural somata and processes in the inner retina. 2) Intense immunoreactivity appeared also in the outer and inner segments and basal processes (pedicles) of cone cells within 6 days or 13 days after hatching. 3) Lack of immunoreactivity was found in the outer segment of rod cells from their appearance during metamorphosis. These findings are discussed with the possible functional roles of taurine in the fish retina: 1) involvement in cell differentiation and/or development; 2) protection of the outer segments against light stimuli; and 3) regulation of neural transmission.

Embryonic development of the inner ear and otolith of the rainbow trout Oncorhynchus mykiss.

The embryonic development of the inner ear, especially the sensory epithelia and otoliths in the rainbow trout Oncorhynchus mykiss, was studied by light and electron microscopy. Light microscopically, the auditory vesicle, saccular otolith and statoacoustic ganglion were first observed by 12 days after fertilization, while the utricular otolith appeared at 15 days after fertilization. Both the saccular and utricular maculae were more developed at 22 days after fertilization, and well developed by 27 days. The crista ampullaris of the horizontal canal was also developed at 27 days after fertilization, while the other cristae were not yet distinguished. Electron microscopically, vesicular structures and short microvilli were found on the sensory epithelia of the maculae by 15 days after fertilization. At 22 days after fertilization, the saccular otolith possessed 7 incremental layers, and developing cilia, microvilli, and aggregates of secretory materials also appeared on the apical surface of the sensory epithelia. At 27 days after fertilization, the apical surface of each hair cell was covered with a hair bundle consisting of a single kinocilium and a bundle of stereocilia. These findings are discussed with special regard to the environmental factors on early development in fishes.

Estimation of the amount of telomere molecules in different human age groups and the telomere increasing effect of acupuncture and shiatsu on St.36, using synthesized basic units of the human telomere molecules as reference control substances for the bi-digital O-ring test resonance phenomenon.

It is well established that the telomeres at the ends of chromosomes are composed of long arrays of (TTAGGG)n x (CCCTAA)n that form a nucleoprotein complex required for the replication and protection of chromosome ends. Throughout the cell cycle, telomeres also contain a protein component related to the proto-oncogene Myb that is known as TRF1 (telomere TTAGGG repeat binding factor 1) that binds to the duplex array of TTAGGG repeats in the telomere. Previous studies have shown that TRF1 appears to play a role in controlling the length of telomeres by acting as an inhibitor of telomerase. The amount of each of the TRF1(C-19) & TRF1(N-19) was identical to the amount of telomere of the same organ of the same apparently normal individual. Using synthesized basic unit of TTAGGG, as well as CCCTAA, as separate reference control substances for the Bi-Digital O-Ring Test of Resonance Phenomenon between 2 identical substances, we were able to non-invasively measure the approximate amount of TTAGGG and CCCTAA units, in both normal and cancerous human cells. We examined about 30 apparently normal subjects (both Asian and Caucasian in both sex). The subjects' ages ranged from infancy to 76 years. Each subject was first examined using TTAGGG as a control substance and then examined using CCCTAA as a control substance. The amount of telomere in various cancer tissues are almost always higher than that of normal tissue of the same organ. The measured amounts of both TTAGGG and CCCTAA were found to be in an average of 1500-1600 ng for human fetus or infancy and decreased with the advance of age in both sex with the exception of the heart, brain, eyes (retina), testes, and ovaries, which usually remain at the level of the infant, or reduced very little. Individuals in the same age group had a similar range of amounts of both TTAGGG and CCCTAA in the same organ of the same individual, (except for those with unusually low telomeres often had chronic degenerative diseases, and those who had exceptionally high telomere levels often had excellent physical conditions or mental acumen). The amounts of measured TTAGGG and CCCTAA molecules before and after acupuncture on St. 36 in adenocarcinomas and small cell carcinoma coexisting in the lung of a 54-yr.-old Asian male were: telomere in adenocarcinoma decreased from 950 ng to 750 ng and telomere in small cell carcinoma decreased from 770 ng to 600 ng. When the cancer treatment is effective, the amount of telomere is reduced towards the value of the normal internal organ. We found that acupuncture on St.36 on apparently normal subjects increased the telomere levels up to a maximum of more than 2 times their telomere levels prior to the treatment, depending on the method of treatment, but frequently increases were between 60% to 100%. Strong Shiatsu performed on St. 36 produced a somewhat lesser effect than acupuncture. We also determined the amounts of TTAGGG and CCCTAA molecules non-invasively in 3 mummified Egyptian sisters from the 8th Century BC on exhibit at the Museo Egizio in Turin, Italy in order to estimate their approximate ages (at the time of death). The amounts of body telomere were 500 ng, 550 ng, and 750 ng. For the prehistoric Iceman (about 3350 B.C. to 3310 B.C) discovered in 1991 in the Italian Otzal Alps at about 3,200 meters altitude, estimated body telomere was about 400 ng and telomere in brain and heart was 1600 ng, similar to that of a contemporary human being. Although these studies are preliminary, the findings may have potential applications not only in anti-aging, cancer treatments, and pathophysiology of brain and heart, but also for the estimation of the difference in the ages of cadavers studied in archeology and forensic medicine.

Immunocytochemical localization of taurine in the pineal organ and retina of an anadromous fish, Plecoglossus altivelis.

Light and electron microscopic immunolocalization of taurine, a sulfur-containing free amino acid, was investigated in the photoneuroendocrine pineal organ and the retinal photoreceptor and pigment epithelial layer of the ayu Plecoglossus altivelis, an anadromous fish. Intense immunostaining was found in the outer segments of pineal photoreceptors and retinal cone-like cells. Moderate but definite immunostaining was found in the cytoplasmic processes of pineal supporting cells, the outer segments of retinal rod-like cells, and the apical processes of pigment epithelial cells. Although the electron microscopic immunogold labeling was not completely coincident with the results of light microscopic immunostaining, concentrated immunogold particles appeared in the inner segments of photoreceptor cells, the cytoplasmic processes of pineal supporting cells, and the apical processes of pigment epithelial cells. These light and electron microscopic findings in taurine immunolocalization were discussed in relation to the functions of taurine known mainly from retinal physiology. It was suggested that the abundant taurine localization may be involved at least in the protection of photoreceptor outer segments against harmful factors, and in the transportation of nutrients and metabolites. The immunostaining for taurine is useful for the discrimination of different types of photoreceptor cells in the pineal organ and retina of fish.

Impression on observing psychic surgery and healing in Brazil which appear to incorporate (+) qi gong energy & the use of acupuncture points.

In December, 1995, the author had the opportunity to observe an elderly psychic healer of East European origin in Sao Paulo, Brazil. This man specialized in cancer treatment by pointing with the fingers of his right hand at his patients, without actually touching them, spending an average of 30 to 40 minutes with each one. The author considered this to be Qi Gong treatment. In March, 1997 the author also observed 2 leading psychic healers in Brazil. One of them, named Rubens Farias, Jr. is a 43 year-old former engineer and computer programmer if European descent, who is commonly known as "Dr. Fritz III" because he is believed to be the spirit of Dr. Adolf Fritz, a German physician who died during World War I, operates through him. The other is "Dr." Hirota, a 53 year old former farmer of Japanese decent who lives near Campinas. About 120 kilometers outside of Sao Paulo and treats large numbers of people daily using indirect and/or hand-on healing techniques. On March 6, 1997, when the author visited "Dr. Fritz III"'s clinic in Sao Paulo with a group of Brazilian physicians, he was informed the about 1,400 patients had come that day. "Dr Fritz III" examined and treated the majority of the patients in less than one minute each, often asking very quick questions and then immediately beginning treatment. Most patients received injections of a dark-brown solution, which, some of the visiting doctors speculated, may be an iodine solution mixed with either alcohol or a local anesthetic. In many patients, he injected this solution near the pathological area or at an acupuncture point near the pathological area. When the needle of the syringe was in the acupuncture pint, he twirled it with his fingers several times and the withdrew it. Minor surgery was performed in about 1/5th of the patients with whom the author observed. Most of the surgical incisions were made on the midline of the tissue over the spine near the pathological area. The clamping of the blood vessels and the closings of the surgical wounds were performed by licensed surgeons or licensed nurses. Major surgery were done by "Dr. Fritz III" who used a rather primitive and unorthodox cutting technique. Except for major surgery, assistance was performed by volunteer nurses, including his wife. After the surgical wounds were closed, gauze band-aids were applied. When the surface of the gauze facing the wound was examined, it showed strong (+) Qi Gong energy according to the Bi-Digital O-Ring Test. Essentially, "Dr. Fritz III"'s treatment consists of acupuncture, injection of iodine with other substances near the pathological area, and (+) Qi Gong energy stored gauze which is applied to the acupuncture point, pathological area, or the site of surgery. "Dr." Hirota is another famous psychic healer whom the author was able to meet and observe in practice while in Brazil. "Dr." Hirota has been practicing for over 20 years. He usually sees patients who come to his clinic in the mornings and he claims to treat 1,000 to 2,000 patients daily between 9 AM and 12 noon. His main treatment also appears to be the application of external Qi Gong energy through the fingers of his right-hand, in combination with Shiatsu Massage and a manual procedure resembling chiropractic manipulation.

Scanning and transmission electron microscopic study on a multilayered basement membrane in the pineal organ of the ayu Plecoglossus altivelis.

The pineal organ possesses highly fenestrated capillaries, and is devoid of the so-called blood-brain barrier. The present study indicated that the pineal epithelium of the teleost fish, ayu Plecoglossus altivelis, possesses an unusually thick and convoluted basement membrane (2.2-2.4 microm in width) which is visible even under the light microscope. This pineal basement membrane was observed by scanning and transmission electron microscopy and its detailed composition and relationships with the fenestrated capillaries and the perivascular space were investigated. As the basement membrane was composed of three to eight layers of basal laminae interspersed with laminae lucidae, we termed it the "multilayered basement membrane". In consideration of our previous demonstration that macromolecules such as HRP are trapped by the basement membrane, it is suggested that this multilayered basement membrane may prevent foreign substances from reaching the pineal epithelium.

Significant mercury deposits in internal organs following the removal of dental amalgam, & development of pre-cancer on the gingiva and the sides of the tongue and their represented organs as a result of inadvertent exposure to strong curing light (used to solidify synthetic dental filling material) & effective treatment: a clinical case report, along with organ representation areas for each tooth.

Because of the reduced effectiveness of antibiotics against bacteria (e.g. Chlamydia trachomatis, alpha-Streptococcus, Borrelia burgdorferi, etc.) and viruses (e.g. Herpes Family Viruses) in the presence of mercury, as well as the fact that the 1st author has found that mercury exists in cancer and pre-cancer cell nuclei, the presence of dental amalgam (which contains about 50% mercury) in the human mouth is considered to be a potential hazard for the individual's health. In order to solve this problem, 3 amalgam fillings were removed from the teeth of the subject of this case study. In order to fill the newly created empty spaces in the teeth where the amalgams had formerly existed, a synthetic dental-filling substance was introduced and to solidify the synthetic substance, curing light (wavelength range reportedly between 400-520 nm) was radiated onto the substance in order to accelerate the solidifying process by photo-polymerization. In spite of considerable care not to inhale mercury vapor or swallow minute particles of dental amalgam during the process of removing it by drilling, mercury entered the body of the subject. Precautions such as the use of a rubber dam and strong air suction, as well as frequent water suctioning and washing of the mouth were insufficient. Significant deposits of mercury, previously non-existent, were found in the lungs, kidneys, endocrine organs, liver, and heart with abnormal low-voltage ECGs (similar to those recorded 1-3 weeks after i.v. injection of radioisotope Thallium-201 for Cardiac SPECT) in all the limb leads and V1 (but almost normal ECGs in the precordial leads V2-V6) the day after the procedures were performed. Enhanced mercury evaporation by increased temperature and microscopic amalgam particles created by drilling may have contributed to mercury entering the lungs and G.I. system and then the blood circulation, creating abnormal deposits of mercury in the organs named above. Such mercury contamination may then contribute to intractable infections or pre-cancer. However, these mercury deposits, which commonly occur in such cases, were successfully eliminated by the oral intake of 100 mg tablet of Chinese parsley (Cilantro) 4 times a day (for average weight adults) with a number of drug-uptake enhancement methods developed by the 1st author, including different stimulation methods on the accurate organ representation areas of the hands (which have been mapped using the Bi-Digital O-Ring Test), without injections of chelating agents. Ingestion of Chinese parsley, accompanied by drug-uptake enhancement methods, was initiated before the amalgam removal procedure and continued for about 2 to 3 weeks afterwards, and ECGs became almost normal. During the use of strong bluish curing light to create a photo-polymerization reaction to solidify the synthetic filling material, the adjacent gingiva and the side of the tongue were inadvertently exposed. This exposure to the strong bluish light was found to produce pre-cancerous conditions in the gingiva, the exposed areas of the tongue, as well as in the corresponding organs represented on those areas of the tongue, and abnormally increased enzyme levels in the liver. These abnormalities were also successfully reversed by the oral intake of a mixture of EPA with DHA and Chinese parsley, augmented by one of the non-invasive drug-uptake enhancement methods previously described by the 1st author, repeated 4 times each day for 2 weeks.

177 cardiovascular risk factors, classified in 10 categories, to be considered in the prevention of cardiovascular diseases: an update of the original 1982 article containing 96 risk factors.

The first comprehensive listing of cardiovascular risk factors was presented in this journal in 1982 in the article, "96 Cardiovascular Risk Factors" (by Y. Omura & S. Heller), which was the most extensive list of cardiovascular risk factors written on the subject at that time. Since then, much research has been carried out to identify cardiovascular risk factors; according to the authors' most recent computer search, close to 9,000 articles appeared between 1982 and 1996. Upon initial review of most of the abstracts of these articles, we were surprised to find that the number of cardiovascular risk factors has increased significantly (79 new factors in addition to those we published in 1982). With a few exceptions (7 risk factors are now considered to be questionable), those we listed in 1982 are still valid today, and have been further confirmed with additional data and improved technology. Through reviewing the abstracts of these articles, we found about 177 cardiovascular risk factors, including most of the 96 previously listed. Of the original 96, we have identified those now considered to be questionable, e.g. taking oral contraceptives, which today contain significantly lower doses of estrogen than in the past and are therefore much safer. All 177 cardiovascular risk factors are classified into the following 10 major categories, with the 11th category listing those factors now considered to be questionable: 1) Nutrition-Related Cardiovascular Risk Factors (33 risk factors) 2) Internal Cardiovascular Risk Factors Identifiable by Laboratory Tests: Abnormal Blood & Tissue Chemistry Findings Related to Cardiovascular Diseases (35 risk factors) 3) Drug, Chemical, Hormonal, and Nutritional Supplement Intake (Including Drug-Drug Interaction and Drug-Food Interaction) As Cardiovascular Risk Factors (34 risk factors) 4) Signs and Symptoms Associated With a High Incidence of Cardiovascular Diseases (33 risk factors) 5) Non-Invasively Detectable Abnormal Laboratory Findings Associated With Cardiovascular Diseases (13 risk factors) 6) Hereditary Cardiovascular Risk Factors (5 risk factors) 7) Environmental Cardiovascular Risk Factors, Including Air Pollution, Electromagnetic Fields, Materials that Contact the Body Surface, Poisonous Venoms, and Insertion of Needle into Infected Body Tissue by Acupuncture of Injection (14 risk factors) 8) Socioeconomic and Demographic Cardiovascular Risk Factors (7 risk factors) 9) Cardiovascular Risk Factors Related to Medical Care (2 risk factors) 10) Co-existence of Multiple Cardiovascular Risk Factors (1 risk factor) 11) Factors Previously Regarded As Cardiovascular Risk Factors, But Now in Question (7 risk factors) While a few factors, like hereditary characteristics, age, and sex, generally cannot be changed, most of the cardiovascular risk factors can be controlled by changing one's lifestyle, maintaining proper dietary intake, and correcting any existing abnormalities once each individual's unique constellation of cardiovascular risk factors is recognized. Some factors can be recognized by individuals themselves, but many other factors require physical examinations and laboratory tests by a physician or properly trained paramedical to be recognized. Medical examinations and blood chemistry and other laboratory tests may be necessary to establish baselines and measure changes over time. Once abnormal parameters are identified, periodic examinations should follow with proper corrective measures monitored by a qualified medical professional.

Inhibitory effect of NaCl on hog kidney mitochondrial membrane-bound monoamine oxidase: pH and temperature dependences.

For a further understanding of the inhibitory effect of NaCl on hog kidney mitochondrial monoamine oxidase (MAO), the activity for benzylamine as substrate was assayed spectrophotometrically in the absence and presence of NaCl for mitochondrial outer membrane preparations as well as whole mitochondria. The effect of CaCl2 was also examined for comparison. The inhibition by NaCl but not CaCl2 was strongly pH dependent. The pH dependence of the inhibitory effect of NaCl in phosphate buffer was parallel to the pH dependence of the MAO activity itself. The point at which the slope of the Arrhenius plot in the absence of NaCl decreases with increasing temperature was to be 32.3 degrees C at pH 7.0 and 30.4 degrees C at pH 7.5 in phosphate buffer, while the Arrhenius plot in the presence of NaCl exhibited discontinuities without change in the slope in small temperature ranges, 39.2 degrees C-40.0 degrees C and 33.0 degrees C-34.2 degrees C. It was estimated that the inhibitory effect of NaCl was due to a pH and temperature sensitive cooperative state change involving MAO protein and boundary lipids, while the effect of CaCl2 could be induced by specific Ca2+ binding to acidic phospholipids.
