To characterize the roles of leptin and insulin in reproductive hormone modulation and offspring viability in over-conditioned ruminants, addressing key gaps in knowledge relative to undernutrition studies. Objective 1: To evaluate offspring production and viability in over-conditioned female and male ruminants. Hypothesis 1: Over-conditioned ruminants will exhibit reduced offspring viability, with increased miscarriage rates in females and sperm abnormalities in males. Objective 2: To characterize leptin and insulin profiles and their effects on GnRH, LH, and downstream reproductive hormones. Hypothesis 2: Over-conditioning disrupts leptin and insulin regulation, inhibiting GnRH and LH surges, and reducing progesterone, estradiol, and testosterone fluctuations. Objective 3: To assess the effects of feed over-supplementation on leptin and insulin efficiency and subsequent GnRH/LH surges. Hypothesis 3: Feed over-supplementation leads to decreased leptin and insulin efficiency, disrupting kisspeptin signaling and reproductive hormone surges in over-conditioned ruminants. References: Harlow, et al. (2022). The Impact of Undernutrition on KNDy Neurons in Female Lambs. Nestor, et al. (2023). KNDy Neurons as the GnRH Pulse Generator in Ruminants. AIM 11: To investigate the potential of KNDy neurons as key modulators of puberty and GnRH activity in ruminants, addressing their role in neuroendocrine reproductive regulation. Objective 1: To evaluate the impact of neurokinin B absence on puberty onset. Hypothesis 1: Puberty will occur in the absence of neurokinin B, albeit at a delayed rate. Objective 2: To assess the functional consequences of removing specific KNDy neuron components. Hypothesis 2: Neurokinin B function will be significantly impaired in the absence of kisspeptins. Objective 3: To explore the potential of KNDy neurons as natural GnRH agonists or antagonists. Hypothesis 3: Isolated KNDy neurons can function as effective exogenous modulators of GnRH activity.

Anti-Semitism аnd viоlence аgаinst Jews in Eurоpe had оccurred for centuries, but during the late nineteenth century in Russia, organized anti-Jewish violence known as [BLANK-1] became common. State officials stood aside as peasants assaulted and killed Jews, looted their homes or shops, and destroyed their property. From 1880-1915, roughly 2 million of Russia’s 4 million Jews emigrated to the United States in order to escape this intense violence and persecution.

At the stаrt оf the nineteenth century, the Qing Dynаsty in Chinа had the mоst prоsperous economy in the world and saw little to gain by trading with the west, which limited trade to Europe and the United States only to the Port of Canton, now called [BLANK-1]. International trade in China was heavily regulated and only licensed Chinese merchants could trade through this port. In order to gain an upper hand in the lucrative China trade, Great Britain increased its sale of Opium to the country. By 1842, Britain had defeated China in the Opium War (caused by China’s desire to end the Opium Trade and Britain’s desire to continue it). From that point on, Great Britain became the dominant trading partner, was granted most-favored nation status, received Hong Kong as a territory, and gained other favorable outcomes. China saw a significant reduction in its autonomy and the Port of Canton was no longer the only source of western trade (nor was that trade very well regulated).
