BACKGROUND Congenital malformations (CMs) are a leading cause of infant disability. Geophysical patterns such as 2‐year, yearly, half‐year, 3‐month, and lunar cycles regulate much of the temporal biology of all life on Earth and may affect birth and birth outcomes in humans. Therefore, the aim of this study was to evaluate and compare trends and periodicity in total births and CM conceptions in two Israeli populations. METHODS Poisson nonlinear models (polynomial) were applied to study and compare trends and geophysical periodicity cycles of weekly births and weekly prevalence rate of CM (CMPR), in a time‐series design of conception date within and between Jews and Muslims. The population included all live births and stillbirths (n = 823,966) and CM (three anatomic systems, eight CM groups [n = 2193]) in Israel during 2000 to 2006. Data were obtained from the Ministry of Health. RESULTS We describe the trend and periodicity cycles for total birth conceptions. Of eight groups of CM, periodicity cycles were statistically significant in four CM groups for either Jews or Muslims. Lunar month and biennial periodicity cycles not previously investigated in the literature were found to be statistically significant. Biennial cycle was significant in total births (Jews and Muslims) and syndactyly (Muslims), whereas lunar month cycle was significant in total births (Muslims) and atresia of small intestine (Jews). CONCLUSION We encourage others to use the method we describe as an important tool to investigate the effects of different geophysical cycles on human health and pregnancy outcomes, especially CM, and to compare between populations.

Expressed sequence tag data were generated from complementary DNA libraries created from cephalothorax, eyestalk, and pleopod
tissue of the black tiger shrimp (Penaeus monodon). Significant database matches were found for 48 of 83 nuclear genes sequenced from the cephalothorax library, 22 of 55 nuclear
genes from the eyestalk library, and 6 of 13 nuclear genes from the pleopod library. The putative identities of these genes
reflected the expected tissue specificity. For example, genes for digestive enzymes were identified from the cephalothorax
library and genes involved in the visual and neuroendocrine system from the eyestalk library. A few sequences matched anonymous
EST or genomic sequences, and others contained mini-satellite or microsatellite repeat sequences. The remainder, 31 from the
cephalothorax library, 25 from the eyestalk library, and 5 from the pleopod library, were sequences of high nucleotide complexity
with no matches in any database searched and thus may represent novel genes.

Rat endometrial explants were cultured in a three-dimensional collagen/endothelial cell matrix to measure angiogenic activity, as represented by migration of vascular endothelial cells towards the explants. Minimal endothelial cell migratory activity was observed with endometrial explants taken during the four-day oestrous cycle and days 3 and 4 of pregnancy. In contrast, a surge of endothelial cell migration occurred in response to endometrial explants taken from day-5-pregnant rats. Activity was found in explants taken approximately 5 h prior to implantation, but returned to minimal levels by day 6 of pregnancy. Endothelial cell migration remained minimal in response to both implantation and intersite tissue explants taken from days 6 and 7 of pregnancy. Endometrium from ovariectomised rats produced no endothelial cell migratory activity as measured by this technique. However, near preimplantation levels of endothelial cell migratory activity could be induced in ovariectomised rat endometrium by administering progesterone for 72 hours. Oestrogen given in conjunction with progesterone had no additional effect. These results demonstrate the presence of an endometrial signal that controls endothelial cell migration, and demonstrate this activity can be induced by progesterone without the addition of oestrogen. 相似文献
