SummaryThe marked seasonal fluctuation in suicide rates observed by Durkheim appears to be diminishing, and in some cases, to have vanished. In this study, suicide data in Britain from 1958 to 1974 were studied by auto-correlational methods. A cyclical variation was found for both men and women. Men showed a single twelve monthly cycle whereas women showed two cycles. No explanation for this difference is immediately apparent.

Progestogen administration is required to oppose naturally produced or administered estrogens to provide endometrial protection. Within HRT regimens, this should be delivered for at least the same duration as that produced during the luteal phase of the monthly cycle and in the recommended doses to protect against the risk of endometrial hyperplasia and endometrial cancer. This includes progestogens administered for 12–14 days a month in sequential regimens and continuous daily intake in continuous combined HRT regimens. Shorter durations and lower doses of progestogen intake are likely to be associated with an increased risk of breakthrough bleeding, endometrial hyperplasia, and endometrial cancer.

Abstract. Eleven healthy women were examined three times a week during the third trimester. A mathematical model (parabolas overlaid with a cosine curve and containing parameters for cycle length, cycle amplitude and phase) was used in a multivariate analysis of changes in serum progesterone, serum aldosterone, serum osmolality and urinary potassium. A highly significant monthly cycle in progesterone and aldosterone and a significant cycle in the urinary excretion rate of potassium were found. The individual rates of increase in serum progesterone and serum aldosterone were different and uncorrelated, and in the monthly cycle there was a phase difference between them. We think that the changes in serum progesterone and serum aldosterone are controlled by different stimuli and that the control of the cyclical component originates in the maternal neuro-endocrine system.

Pangasius sp. is a mainstay commodity in Indonesia. Economically Pangasius sp., is promising to be developed as an export commodity. Hatcheries of Pangasius sp. are carried out at the Marine and Fisheries Service Branch Subang. Data analysis in this research used quantitative descriptive analysis and qualitative descriptive analysis. The results of the research that Pangasius sp. can issue 323.500 eggs per broodstock with the egg weight released by each broodstock was 300 gr. The productivity of Pangasius sp. eggs can reach 5.176.000 eggs with Hatching Rate 99.6 %. The survival rate was 85 %. Analysis of the Pangasius sp. hatchery business after analyzing the R/C ratio resulted in a value of 2.9 where this business could provide a large income in a monthly cycle.

Monthly Cycle

Abstract. Eleven healthy women were examined three times a week during the third trimester. The possibility of monthly cyclical changes in the serum concentrations of cortisol, placental hCG and fetoplacental estradiol was tested because of previous findings of highly significant monthly cycles in aldosterone and progesterone. A semi-parametric statistical model was used and a highly significant monthly cycle in serum cortisol was found, whereas the amplitude for a cycle in hCG was barely significant and non-significant for estradiol. The previous findings of monthly cycles in aldosterone and progesterone, using a parametric multivariate model, were retested by the semiparametric method employed for the present publication. The findings of highly significant cycles in aldosterone and progesterone were corroborated. We think that the results indicate the existence of an adrenocortical cycle. We think that the monthly ovarian cycle in the non-pregnant state is paralleled by an adrenocortical cycle, where changes in aldosterone are "linked" with changes in progesterone and changes in cortisol with changes in estrogens. During pregnancy the adrenocortical cycle persists, probably controlled by the maternal hypothalamus. The physiological background for this monthly endocrine cycle during pregnancy is enigmatic.
