| Relationship among cholesterol, superoxide anion and endothelium-dependent relaxation in diabetic rats Kobayashi, T. and K. Kamata (1999), Eur J Pharmacol 367(2-3): 213-22. Abstract: The purpose of the present study was to investigate the time course of changes in plasma low-density lipoprotein (LDL) cholesterol, tissue lipid peroxidation, the expression of hepatic LDL-receptor mRNA and aortic superoxide dismutase, and the relaxation response to acetylcholine in streptozotocin-induced diabetic rats. Plasma cholesterol and LDL levels were significantly increased in both 4- and 10-week diabetic rats. The tissue malonic dialdehyde content in aortas was increased in 10-week compared to 1- or 4-week diabetic rats. The expression of mRNA for LDL receptor mRNA in the liver showed a decrease in both 4- and 10-week diabetic rats. Hepatic LDL-receptor binding activity decreased significantly in 10-week diabetic rats, and decreased binding activity in diabetic rats was improved by the chronic administration of cholestyramine. The relaxation responses to acetylcholine in helical strips of the aorta precontracted with noradrenaline were significantly decreased in 10-week, but not in 1- or 4-week streptozotocin-induced diabetic rats. The decreased relaxation response to acetylcholine was improved by chronic cholestyramine. Both the expression of Mn-superoxide dismutase mRNA and the activity of superoxide dismutase in the aorta were decreased in 10-week, but not in 4-week diabetic rats. From time-course studies, our data suggest that not only increased LDL cholesterol but also decreased activity of superoxide dismutase are responsible for the decreased relaxation response induced by acetylcholine. |

| Relationship between abnormal cholesterol synthesis and retarded learning in rats Xu, G., R. J. Servatius, et al. (1998), Metabolism 47(7): 878-82. Abstract: We examined the relationship between brain sterol composition and associative learning (classical conditioning of the eyeblink response) in newly weaned rats fed BM 15.766 (BM) for 4 months. This compound inhibits 7-dehydrocholesterol-delta7-reductase, which catalyzes the conversion of 7-dehydrocholesterol to cholesterol, the last step in the synthetic pathway. As countertreatment, half of the BM-treated rats were fed 2% cholesterol during the last 2 months. With BM, cholesterol concentrations declined 91% in plasma, but with cholesterol feeding, the levels increased 50% compared with baseline values. 7-Dehydrocholesterol, which was not detected at baseline, increased to 55% of plasma sterols with BM but decreased to 5% of total plasma sterols when cholesterol was added. With BM, brain cholesterol levels decreased 60% and did not increase after cholesterol was added. However, 7-dehydrocholesterol, which comprised 39% of brain sterols with BM, decreased to 31% (P <.05) when cholesterol was fed. Hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase activity in the liver increased 2.2-fold with BM and declined 95% after adding cholesterol, but did not change in the brain. BM treatment for 4 months prevented learning of the conditioned eyeblink response as compared with controls. In contrast, BM-treated rats supplemented with cholesterol acquired the conditioned eyeblink response. Chronic inhibition of 7-dehydrocholesterol-delta7-reductase reduced cholesterol and increased 7-dehydrocholesterol levels in plasma and brain, and was associated with impaired learning. Cholesterol feeding corrected plasma and hepatic sterol levels and reduced brain 7-dehydrocholesterol concentrations to reestablish normal learning. |

| Relationship between apolipoprotein E mRNA expression and tissue cholesterol content in rat adrenal gland Prack, M. M., M. Nicosia, et al. (1991), J Lipid Res 32(10): 1611-8. Abstract: Among extrahepatic tissues the adrenal gland has one of the highest concentrations of apoE mRNA and the highest rate of apoE synthesis. In the present investigation several previously described in vivo treatments were used to assess the relationship between apoE expression and cellular cholesterol in the rat adrenal gland. Treatment of rats with 4-aminopyrazolo3,4-dpyrimidine (4-APP) to lower serum cholesterol concentration and deplete adrenal gland cholesterol content decreased adrenal gland apoE mRNA concentration. These adrenal responses were blocked by dexamethasone (DEX) suggesting that the effect of 4-APP occurred indirectly via stimulation of the adrenal gland by endogenous adrenocorticotrophic (ACTH). Relative to control rats, DEX treatment increased both adrenal gland cholesterol content and apoE mRNA concentration. Concurrent ACTH and DEX administration reduced both adrenal gland cholesterol content and apoE mRNA concentration relative to DEX-treated rats. ACTH administration also rapidly decreased adrenal gland apoE mRNA concentration and cholesterol content in rats pretreated with DEX. In all the above experiments, adrenal gland cholesterol content and apoE mRNA concentration were positively correlated (r = 0.78, P = 0.0001). In contrast, aminoglutethimide treatment, which blocks adrenal gland steroidogenesis and greatly increases adrenal gland cholesterol content, was without effect on apoE mRNA concentration. ACTH administration to rats treated with DEX + aminoglutethimide resulted in decreased adrenal apoE mRNA despite greatly increased adrenal cholesterol content. This uncoupling of adrenal gland cholesterol content and apoE mRNA concentration suggests that apoE mRNA expression and cellular cholesterol are regulated independently by ACTH. |
| Relationship between attempted suicide, serum cholesterol level and novelty seeking in psychiatric in-patients Guillem, E., A. Pelissolo, et al. (2002), Psychiatry Res 112(1): 83-8. Abstract: This study sought to compare the serum cholesterol levels of psychiatric in-patients, with and without recent suicidal behavior. The hypothesis was that the temperament dimension novelty seeking (NS) would be an intermediary variable, correlated with both serum cholesterol level and suicidal behavior. The study included 155 psychiatric in-patients, 21.9% (n=34) of whom had recently attempted suicide. Their cholesterol level was compared to that of patients with no suicide attempt. The NS dimension was explored with the aid of Cloninger's Temperament and Character Inventory. Significantly lower average cholesterol levels were found in women who had attempted suicide before hospitalization than for the others (4.71 mmol/l+/-0.83 vs. 5.52 mmol/l+/-1.36). Similar results were not found for men. However, the average NS scores did not differ according to suicide attempts in women or in men, and the scores of NS were not correlated with cholesterol level. This study confirms an association between low cholesterol and suicidal behavior in women only, but this association seems independent from the NS personality dimension. The absence of a correlation between serum cholesterol levels and suicidal behavior in men could be linked to the small number of men included in the study. |
| Relationship between bioavailability and hypocholesterolemic activity of YM17E, an inhibitor of ACAT, in cholesterol-fed rats Uchida, T., K. Aoyama, et al. (1998), Atherosclerosis 137(1): 97-106. Abstract: The relationship between bioavailability and the serum cholesterol-lowering effect of YM17E, an ACAT inhibitor was investigated. Serum cholesterol levels in cholesterol-fed rats decreased after both oral and intravenous administration of YM17E. Marked inhibition of cholesterol absorption was observed after oral administration, but not after intravenous administration. YM17E and its five active metabolites were primarily distributed in the liver after intravenous administration, but in small intestine and liver after oral administration. Hepatic ACAT activity in cholesterol-fed rats was inhibited by intravenous administration. Cholesteryl ester input into plasma by Triton WR-1339 treatment to the rats was inhibited by intravenous administration of YM17E. Plasma clearance of 125I-LDL in cholesterol-fed rats increased after YM17E treatment suggesting a decrease in LDL production. These results indicate that the hypocholesterolemic effect of intravenous YM17E was due to hepatic ACAT inhibition, not an inhibition of intestinal cholesterol absorption. The contribution of ACAT inhibition in small intestine and liver on the pharmacological effect could be explained by plasma inhibitor concentration after oral or intravenous administration of YM17E. From these results, it is concluded that the change in bioavailability of ACAT inhibitors change the mechanism of hypocholesterolemic effects, shifting the relative contributions of small intestinal and hepatic ACAT inhibition. |
| Relationship between body mass index (BMI) and changes in plasma total and HDL-cholesterol levels during treatment of hypertension in African patients Ahaneku, J. E., O. E. Agbedana, et al. (1995), Acta Med Okayama 49(5): 267-70. Abstract: Eighty-one adult Nigerians with essential hypertension were randomly allocated to receive doxazosin, hydrochlorothiazide/amloride, or amlodipine. In each group, the patients were further classified as obese and non-obese, and total cholesterol as well as high density lipoprotein (HDL) cholesterol was determined before and after the 3-month treatment period. The total cholesterol level was significantly reduced in the non-obese patients, but did not show any significant change in the obese patients after doxazosin therapy, indicating the beneficial effects of doxazosin therapy in non-obese patients. The levels of total cholesterol increased and HDL cholesterol decreased in both the obese and the non-obese patients after hydrochlorothiazide/amloride therapy. Amlodipine treatment did not cause any significant change in the total and HDL cholesterol levels in both the obese and non-obese patients. These findings are worthy of consideration by clinicians and researchers when selecting the most appropriate drug for antihypertensive pharmacotherapy. |
| Relationship between body mass index, serum cholesterol, leisure-time physical activity, and diet in a Mediterranean Southern-Europe population Schroder, H., J. Marrugat, et al. (2003), Br J Nutr 90(2): 431-9. Abstract: The aim of the present study was to determine the relationship of BMI with other cardiovascular risk factors, leisure-time physical activity and diet. Participants were recruited in a cross-sectional population-based survey in a southern-Europe Mediterranean population (Spain); cardiovascular risk factors were measured, and leisure-time physical activity and diet intake were evaluated. Linear regression analysis adjusted for several confounders showed a significant, direct association of BMI and total cholesterol (P<0.005) and LDL-cholesterol (P<0.006), in men. HDL-cholesterol was inversely related to BMI in both sexes (P<0.0001). Higher BMI was more frequent in less-active men (P<0.04) but not in women. BMI increased significantly (P<0.0001) by 1.92 kg/m(2) with each 4.18 MJ consumed in men but not in women. Dietary intakes of carbohydrate (P<0.03), total fat (P<0.03) and saturated fatty acids (P<0.02) were directly associated with BMI in men but not in women, in whom protein intake was correlated (P<0.001) with BMI. Linear regression models including dietary components explained up to 10.6 and 21.1 % of BMI variability in men and women, respectively. Sex differences in the association of BMI with total cholesterol, and LDL-cholesterol, may account for the lower risk for CHD in women compared with men of similar BMI reported in the literature for the southern-Europe Mediterranean region. An increases of BMI may be more deleterious in populations in which it is accompanied by other risk factors such as a higher intake of total fat and, particularly, of saturated fatty acids, or lower leisure-time physical activity. |
| Relationship between carotid atherosclerosis and erythrocyte membrane cholesterol oxidation products in type 2 diabetic patients Miwa, S., M. Inouye, et al. (2003), Diabetes Res Clin Pract 61(2): 81-8. Abstract: Oxidative stress is well known to play a critical role in atherosclerosis. This study investigated an appropriate marker of in vivo oxidative stress and whether it could predict macroangiopathy in diabetes. The lipid composition of erythrocyte membranes was analyzed in 64 type 2 diabetic patients using gas chromatography-mass spectrometry (GC/MS). After 3,5,7-cholestatriene (a cholesterol oxidation product) was detected, the peak height ratio of 3,5,7-cholestatriene to cholesterol was calculated. Carotid artery intima-media thickness (IMT) was measured to evaluate atherosclerosis. The IMT was independently associated with 3,5,7-cholestatriene (P<0.0001), age (P=0.0001), and HbA1c (P=0.05) by stepwise multiple regression analysis (R2=0.416, P<0.0001). When the subjects were divided into groups with or without carotid atherosclerosis, the 3,5,7-cholestatriene level was significantly higher in 37 subjects with atherosclerosis than in 27 subjects without it (0.41+/-0.22 vs. 0.16+/-0.16%, P<0.0001). Among 38 subjects with no clinical manifestations of macroangiopathy and long-term good glycemic control, the 3,5,7-cholestatriene level was also significantly higher in the patients with carotid atherosclerosis than in those without it (0.40+/-0.20 vs. 0.18+/-0.12%, P=0.0003). These data suggest that the 3,5,7-cholestatriene level in erythrocyte membrane lipids may be a useful predictor of subclinical atherosclerosis. |
| Relationship between changes in dietary sucrose and high density lipoprotein cholesterol: the CARDIA study. Coronary Artery Risk Development in Young Adults Archer, S. L., K. Liu, et al. (1998), Ann Epidemiol 8(7): 433-8. Abstract: PURPOSE: Cross-sectional data from several observational studies have suggested that dietary sucrose may be inversely associated with high density lipoprotein cholesterol (HDL-C). This study examined associations between energy from dietary sucrose and HDL-C at baseline, year 7 and longitudinally (year 7 minus baseline) in a cohort of young black and white men and women from the Coronary Artery Risk Development in Young Adults (CARDIA) study. METHODS: The sample included 4734 black men, black women, white men and white women, ages 18-30 years, in 1985-86 (baseline); 3513 at year 7; and 3335 for longitudinal analyses. Multivariate analyses was used with adjustment for age, BMI, cigarettes smoked per day, physical activity score, and alcohol intake. RESULTS: Multivariate analyses indicated that energy intake from sucrose was inversely associated with HDL-C for each race-gender group at baseline, year 7, and longitudinally from baseline to year 7. This association was significant at baseline for black men, and white men and women (p < 0.01); at year 7 for white men and black women (p < 0.01), and longitudinally for white men, white women, and black women (p < 0.05). CONCLUSIONS: The consistent inverse associations between energy from dietary sucrose and HDL-C observed in both cross-sectional and longitudinal analyses, and in different race and gender groups in CARDIA suggest that lowering dietary sucrose intake may be beneficial for those who may have low HDL-C. |
| Relationship between changes in serum thyrotropin and total and lipoprotein cholesterol with prolonged Antarctic residence Harford, R. R., H. L. Reed, et al. (1993), Metabolism 42(9): 1159-63. Abstract: Antarctic residence (AR) is associated with a 50% increase in the thyrotropin (TSH) response to TSH-releasing hormone (TRH) and an expanded triiodothyronine (T3) distribution volume and extravascular hormone pool, collectively called the polar T3 syndrome. To investigate the possible biologic significance of this syndrome, we studied the relationship between nonstimulated TSH and serum lipid profiles in nine subjects, once while in California and monthly during 9 months of AR. We measured serum levels of TSH, total thyroxine (TT4), free T4 (FT4), total T3 (TT3), free T3 (FT3), thyroid-binding globulin (TBG), total cholesterol (T-CHOL), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), dietary cholesterol (D-CHOL), dietary fat (D-FAT), and dietary kilocalories at each month. The paired mean monthly change from baseline was used to determine significance. The group's mean levels of TSH (approximately 30%), TBG (approximately 16%), T-CHOL (approximately 4%), HDL-C (approximately 10%), and D-CHOL (approximately 19%) increased with AR (P <.05). Small but significant decreases (P <.05) were observed in the mean changes of TT4 (approximately 8%), FT4 (approximately 6%), and TT3 (approximately 6%). FT3, D-FAT, dietary kilocalories, body weight, TG, and the calculated low-density lipoprotein (LDL-C) were unchanged with AR. A significant rate of change (P <.05) during AR was also calculated from the slope of a fitted logarithmic function for TSH (0.96 +/- 0.31 mU.L-1 x mo-1), TBG (61.19 +/- 12.29 nmol.L-1 x mo-1), TT3 (0.09 +/- 0.04 nmol.L-1 x mo-1), TT4/TBG (-0.06 +/- 0.01/mo), TT3/TBG (-8.49 +/- 1.98 x 10(-4)/mo), and TG (-0.33 +/- 0.15 mmol.L-1 x mo-1).(ABSTRACT TRUNCATED AT 250 WORDS) |
| Relationship between cholesterol and fibrinogen in two populations of different geographical location of Catalonia Rodriguez Cristobal, J. J., C. A. Villaverde Grote, et al. (2004), Rev Clin Esp 204(8): 405-9. Abstract: OBJECTIVES: Verification of the following in two different geographical location populations (seashore and mountain) with cardiovascular symptomatology: 1) the prevalence of hyperfibrinogenemia and possible correlation with cholesterolemia; 2) the differences between both populations in the profiles of these parameters. DESIGN: Cross-sectional descriptive study. CONTEXT: Primary Care. PARTICIPANTS: Three hundred and seventy five patients who went to two hospitals between May 1995 and July 1998. In the seashore center 256 patients and in the mountain center 119 patients. MAIN MEASUREMENTS: Clinical history and analytical parameters. Fibrinogen (FBG), indirect prothrombin time, enzymatic cholesterol (CLT) Utachi 717. The patients were sorted out into 4 groups: 1) high FBG > 300 mg/dl and high CLT > 240 mg/dl; 2) high FBG > 300 and low CLT < 240; 3) low FBG < 300 and high CLT > 240, and 4) low FBG < 300 and low CLT < 240. RESULTS: Levels of FBG: homogeneous between groups 1 and 2 (high) and 3 and 4 (low), and different between upper and lower groups. Cholesterol showed the same behavior. Group 1 with a similar number of patients in mountain and seashore (40% and 41%). Group 2 with 42.8% of patients from mountain and 26.9% from seashore. Groups 3 and 4 are presented with lower percentages. We did not find correlation between the levels of FBG and those of CLT. CONCLUSIONS: Predominance of patients with high FBG and normal CLT (group 2) in the mountain cohort, in contrast with a higher prevalence of normal FBG and high CLT (group 3) in the seashore cohort. In participants with normal levels or with high risk the variations of the FBG were not dependent nor related to those of CLT. |
| Relationship between cholesterol levels and depression in the elderly Cadeddu, G., P. Fioravanti, et al. (1995), Minerva Med 86(6): 251-6. Abstract: The aim of our study is to evaluate the possible association between lower plasma cholesterol and depression in the elderly. 140 subjects over 65 years old of both sexes were enrolled, of which 60 were affected by depression (DSM-III-R and Hamilton test) and 80 composed a control group homogeneous for sex and age with the previous one. Plasma cholesterol, HLD-cholesterol (HDL-C), LDL-cholesterol (LDL-C) and triglycerides were measured. A statistically significant difference between cholesterol and LDL-C (p < 0.001) was noted in the total group, in both males and females. Such modifications were independent of sex. In the group with lower cholesterol (cut-off < = 160 mg/dl) a prevalence of depression three times greater than subjects with higher cholesterol was found. In conclusion, the authors recommended a prudent use of lipid-lowering medications in the elderly because of its uncertain benefits. |
| Relationship between cholesterol sulfate and intercellular cohesion of the stratum corneum: demonstration using a push-pull meter and an improved high-performance thin-layer chromatographic separation system of all major stratum corneum lipids Serizawa, S., K. Osawa, et al. (1992), J Invest Dermatol 99(2): 232-6. Abstract: To investigate the role of cholesterol sulfate (CS) as an intercellular glue or cement in the stratum corneum, we compared the relationship between CS levels and magnitude of the intercellular cohesion of the stratum corneum between the palm and the upper arm. Using a push-pull meter, the palm displayed approximately seven times the magnitude of cohesion of the stratum corneum as the upper arm (n = 11). CS and other stratum corneum lipids were extracted from the palm and the upper arm (n = 22) by a cup method and determined by our improved high-performance thin-layer chromatography (HPTLC). Despite a great difference in the magnitude of cohesion (p less than 0.01), CS levels and ratios of CS to ceramides and CS to cholesterol in the stratum corneum showed no significant differences between the palm and the upper arm. Our results suggest that differences in CS cannot account for the differences in cohesion between palm and upper arm. |
| Relationship between cholesterol trafficking and signaling in rafts and caveolae Fielding, C. J. and P. E. Fielding (2003), Biochim Biophys Acta 1610(2): 219-28. Abstract: Caveolae and lipid rafts are two distinct populations of free cholesterol, sphingolipid (FC/SPH)-rich cell surface microdomains. They differ in stability, shape, and the presence or absence of caveolin (present in caveolae) or GPI-anchored proteins (enriched in lipid rafts). In primary cells, caveolae and rafts support the assembly of different signaling complexes, though signal transduction from both is strongly dependent on the presence of FC. It was initially thought that FC promoted the formation of inactive reservoirs of signaling proteins. Recent data supports the concept of a more dynamic role for FC in caveolae and probably, also lipid rafts. It is more likely that the FC content of these domains is actively modulated as protein complexes are formed and, following signal transduction, disassembled. In transformed cell lines with few caveolae, little caveolin and a preponderance of rafts, complexes normally assembled on caveolae may function in rafts, albeit with altered kinetics. However, caveolae and lipid rafts appear not to be interconvertible. The presence of non-caveolar pools of caveolin in recycling endosomes (RE), the trans-Golgi network (TGN) and in mobile chaperone complexes is now recognized. A role in the uptake of microorganisms by cells ascribed to caveolae now seems more likely to be mediated by cell surface rafts. |
| Relationship between coffee and blood cholesterol in a sample of working women Ruiz-Lapuente, M. A., L. Armadans Gil, et al. (1995), Med Clin (Barc) 105(18): 687-90. Abstract: BACKGROUND: Experimental studies have demonstrated that unfiltered coffee increases cholesterolemia. In Spain, filtered coffee is mainly consumed and its effect on cholesterolemia is controversial. METHODS: The relationship between coffee intake and the serum levels of total cholesterol was transversally studied in a population of 609 women between 18 to 65 years in age. The questionnaire and analyses were carried out in the context of periodic health examination. RESULTS: The consumption of coffee was positively associated with cholesterolemia in subjects under 30 years of age (p < 0.01) and in the group from 30 to 45 years in age (p < 0.05). This association was found to be statistically significant on multivariant analysis (multiple lineal regression) after adjusting for age, body mass index, cholesterol consumed in the diet, smoking, alcohol consumption and physical activity. CONCLUSIONS: Coffee was found to increase cholesterolemia in the female population and therefore a reduction in coffee intake would be recommendable in hypercholesterolemic subjects. |
| Relationship between exercise-induced changes in serum and hepatic cholesterol metabolism in rats Abe, T., T. Sakamoto, et al. (1990), Ann Physiol Anthropol 9(4): 321-7. Abstract: The purpose of the present study was to determine the effects of exercise training on serum cholesterol level and hepatic cholesterol metabolism in rats. Twenty-four male Wistar strain rats, aged 6 weeks, were assigned to one of three experimental groups; control (n = 8), exercised 20 minutes a day (E20, n = 8), and exercised 60 minutes a day (E60, n = 8). Rats were sacrificed after ten weeks exercise. The levels of serum total cholesterol and HDL-cholesterol in the group E20 and group E60 were lower than that of control, 8% and 24% (p less than 0.01) for the total cholesterol and 10% and 24% (p less than 0.05) for the HDL-cholesterol, respectively. The activity of HMG-CoA reductase in liver microsome was significantly higher in the group E60 than that of control. The hepatic microsomal HMG-CoA reductase activity was negatively related to serum total (r = -0.62, p less than 0.01) and HDL (r = -0.58, p less than 0.01) cholesterol levels. From these results, we concluded that the enhancement of the cholesterol metabolism in the liver by exercise is a major course of the exercise-induced change in serum cholesterol of Wistar rats. |
| Relationship between expression of CD40-CD40 ligand system and serum cholesterol levels in patients with hypercholesterolemia Yan, J. C., Z. G. Wu, et al. (2004), Chin Med J (Engl) 117(7): 1101-3. |
| Relationship between food habits and serum cholesterol levels in a suburban population in Argentina Marcilla de Parada, N., E. Cozza, et al. (1999), Arch Latinoam Nutr 49(4): 333-7. Abstract: Studies of cholesterol levels in a population of Gran Buenos Aires was made in 1983, 1988, 1993 and 1996, and the Argentinian alimentary habits in this period were analyzed. It was noticed a change in food consumption, with reduction in the intake of fatty foods, such as meat, butter, milk, and other dairy products, with the concomitant increment in fiber rich products and oil, meat and dairy products reduced in fats. Changes in serum cholesterol level were analysed in 3051 persons along 1983-1996. They were grouped according their age and sex: A) 1-6 years old, B) 6-12, C) 12-17, D) 17-30, E) 30-60, F) 60-80. It was observed an increment in cholesterol level with age. For each group during the first 10 years of study was noticed a constant decrease in total cholesterol being higher in women than in men and according with the alimentary changes. Group D in 1983 became group E in 1993, maintained their cholesterol level along 10 years of life, being lower than the corresponding E group of 1983, while the older ones did not present differences. Values of cholesterol/cholesterol-HDL index over 6.5 correlate with a high incidence in cardiovascular diseases. The 40% of the population studied during 1993 and 1996 was evaluated, and the maximum average value found was 4.90. These results suggest that reduction in fat intake and diversification in food consumption during this period has contributed to decrease cholesterol levels and cholesterol/cholesterol-HDL index, particularly in younger than 30 years old and women, contributing to reduce metabolical cardiovascular diseases. |
