This study investigated the effects of the herd, cow parity, the insemination protocol and season on the incidence of pregnancy loss (PL) in dairy herds. Furthermore, we determined the downstream effects of PL on reproductive performance and its economic impact. The overall incidence rate of PL was 6.9% in 1,001 pregnant cows and its incidence peaked (p < 0.01) during the second trimester of ge...

Introduction* A function f: V —>W between real vector spaces is piecewise-linear (PL) if there exists a partition of V into "open polyhedra" X€ (i.e., relative interiors of polyhedra) such that / is affine on each Xt. (As distinct to the case of PL-topology, no continuity is required of /.) Images and preimages under PL-maps give rise to finite unions of open polyhedra, or PL-seίs; conversely P...

Dogs were unable to learn "same-different" differentiation of pairs of photic stimuli when continuous light (CL) and pulsing light (PL) were presented in four combinations: CL-PL and PL-CL served as S(D) (positive instrumental conditioned stimulus), whereas CL-CL PL-PL were S delta (inhibitory stimulus). Also the dogs which have learned this task with tones were unable to transfer to photic sti...

Objectives: Pleomorphic lobular carcinoma (PL) is an aggressive subtype of invasive lobular carcinoma. There are few case series reporting on this aggressive form of breast cancer. This report features a descriptive and survivorship comparison of a large case series of PL reviewed by a single breast pathologist. Methods: From 1993-2010 we retrospectively reviewed 198 cases of invasive lobular c...

Amputees may experience stump pain (SP), phantom limb (PL) sensations, pain, and/or a general awareness of the missing limb. The mechanisms underlying these perceptions could involve nervous system neuroplasticity and be reflected in altered sensory function of the residual limb. Since little is known about the progression of post-amputation sensory phenomena over time, we longitudinally evalua...

Evaluation of Tracking Regimes for, and Security of, PLI Systems

The present study aimed to analyze the characteristics of polyethylene glycol (PEG)ylated carboplatin liposomes (PL-CBPs), including size, stability, their release, entrapping and loading efficiencies, and their antitumor and antimetastatic effects on the lymph nodes. The PL-CBPs were prepared using PEG-2000 with the thin film hydration method. The liposome size and release, entrapping and load...

Piperlongumine has anti-cancer activity in numerous cancer cell lines via various signaling pathways. But there has been no study regarding the mechanisms of PL on the lung cancer yet. Thus, we evaluated the anti-cancer effects and possible mechanisms of PL on non-small cell lung cancer (NSCLC) cells in vivo and in vitro. Our findings showed that PL induced apoptotic cell death and suppressed t...

The use of a prodrug, a conjugate of an active drug with a lipophilic substituent, is a good way of increasing the cutaneous absorption of a drug. However, the activity of dermal hydrolases has rarely been investigated in humans, or experimental animals. In the present study, we focused on the identification of rat dermal esterases and the hydrolysis of a prodrug during permeation across rat sk...
