A Simple Proof for the Cycle Double Cover Conjecture [PDF]
arXiv, 2018 Given a bridgeless graph G, the well-known cycle double cover conjecture posits that there is a list of cycles of G, such that every edge appears in exactly two cycles. In this paper, we prove the cycle double cover conjecture. More precisely, we prove the Goddyn's conjecture as a stronger version of the cycle double cover conjecture which states that ...

Cell Proliferation, EarlyView.Our study demonstrated the downregulation of GPD1L and its mediated glycerophospholipid metabolism dysfunction in patients with diminished ovarian reserve. Moreover, we verified that GPD1L knockdown leads to increased cell apoptosis and mitochondrial dysfunction of KGN cells, as well as impaired oocyte quality.

Finding Short Cycles in an Embedded Graph in Polynomial Time [PDF]
arXiv, 2008 Let ${\cal{C}}_1$ be the set of fundamental cycles of breadth-first-search trees in a graph $G$ and ${\cal{C}}_2$ the set of the sums of two cycles in ${\cal{C}}_1$. Then we show that $(1) {\cal{C}}={\cal{C}}_1\bigcup{\cal{C}}_2$ contains a shortest $\Pi$-twosided cycle in a $\Pi$-embedded graph $G$;$(2)$ $\cal{C}$ contains all the possible shortest ...

Phospholipase A\u3csub\u3e2\u3c/sub\u3e Expression During the Estrous Cycle and Early Pregnancy [PDF]
, 2008 Acute control of prostaglandin production is essential for normal estrous cyclicity and maintenance of early pregnancy. The rate limiting step for prostaglandin production is the activation of Phospholipase A2.

Estrogen synthesized in the central nervous system enhances MC4R expression and reduces food intake
The FEBS Journal, EarlyView.Estrogen is regulated by the rate‐limiting enzyme aromatase. This study examines how neuroestrogens, estrogen produced in the brain, regulate appetite through the hypothalamus. Using ovariectomized, aromatase knockout, and brain‐specific aromatase‐restored mice, the study found that neuroestrogens suppress appetite by influencing genes like Mc4r.
