Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

Insect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Studies on Egg Quality : I : Introductory Note on Variations in Yolk Color

Poultry Science, 1926
Abstract That yolks vary in color has been known for a long time but the causes of these variations have received little consideration. Recently however they have assumed commercial importance, since during the last few years a premium has been paid in the New York market for eggs with pale yolks, their color being judged by their shadow when candled.

Effect of Alfalfa Meal, Corn Gluten Meal and Other Dietary Components on Egg Yolk Color

, 1962
THE COLOR of egg yolks or their degree of pigmentation has a definite effect on visual estimates of quality. There is considerable variation in consumer preference for egg yolk color (Jasper and Cray, 1953; Slocum and Swanson, 1954). For the graded shell

Comparative Population Genetics of Two Alvinocaridid Shrimp Species in Chemosynthetic Ecosystems of the Western Pacific

Integrative Zoology, EarlyView.
Little is known about the population divergence and gene flow of deep‐sea animals living in disjunct hydrothermal vents and cold seep habitats. Taking advantage of samples collected from multiple cruises across a huge distance of >5000 km, we revealed the differential population divergence pattern and gene flow in two congeneric species of shrimps ...

Yolk Color, Candled Egg Grade and Xanthophyll Availability From Dietary Natural Pigmenting Ingredients ,

Poultry Science, 1975
Abstract Pigment-depleted caged egg-type hens were fed 5, 10, 15 and 20 mg. of xanthophyll per kg. of feed; the xanthophyll levels were obtained from various combinations of white corn, yellow corn, alfalfa meal and corn gluten meal. Beta-apo-8′-carotenal, at the same dietary levels, was used as a standard. Eggs were collected at weekly intervals for

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

Andrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,
