Is Autologous Platelet Activation The Key Step In Ovarian Therapy For Fertility Recovery And Menopause Reversal?, Natalie S. Rickers, E. Scott Sills

BioMedicine

Platelets are a uniquely mammalian physiologic feature. As the only non-marine vertebrates to experience menopause, humans have a substantial post-reproductive lifespan and are believed to have a limited, non-renewable oocyte supply. Ovarian reserve typically declines after about age 35yrs, marking losses which cannot be recovered by available fertility medications. When in vitro fertilization fails due to low or absent ovarian response, gonadotropin adjustments are often ineffectual and if additional oocytes are occasionally harvested, egg quality is usually poor. This problem was confronted by Greek researchers who developed a new surgical method to insert autologous platelet-rich plasma (PRP) into ovaries; the …

Optimum Synthesis Of Au@Ag Nanoparticle As Plasma Amplifier To Detect Trace Concentration Of Afb1 Via Object-Binder-Metal Sers Method, Wenwen Chen, Qiang Chen, Wei Zhang, De Zhang, Zhi Yu, Ying Song, Xiubing Zhang, Dejiang Ni, Pei Liang

Journal of Food and Drug Analysis

The problem of aflatoxin contamination emerged gradually in the field of food safety. Surface-enhanced Raman spectroscopy (SERS) is an ultra-sensitive and non-destructive spectroscopy technology with extensive application prospects in the detection field. In this paper, with the detection of AFB1 as the target, Au@Ag NPs substrate with uniform morphology and strong SERS effect was prepared. Furthermore, the intermediates formed by hydrogen bonding between AFB1 and melamine facilitate the binding of toxin molecules to the substrate. Moreover, the AFB1-melamine-Au@Ag NPs detection system was established by optimizing the melamine dosage, and the limit of detection can reach 10^-8 mol/L (M). In …

Journal of Food and Drug Analysis

This study developed a simple and rapid strategic technique to detect ractopamine (chemical growth-promoting agent) in pork. Two highly sensitive and specific gold nanoparticle-based portable sensors, i.e., localized surface plasmon resonance (LSPR) sensors, and lateral flow immunoassay (LFIA) strips were developed to detect veterinary drug residues in food products, that have detrimental effects on humans. Optimization studies were conducted on several sensor devices to improve sensitivity. Each sensor comprised functionalized gold nanoparticles conjugated with ractopamine antibodies. The LSPR sensor chip achieved excellent detection sensitivity = 1.19 fg/mL and was advantageous for quantitative analysis due to its wide dynamic range. On …

Immunohistochemical Expression Of Estrogen Receptors, Progesterone Receptors, And Human Epidermal Growth-Factor Receptor 2/Neu In Epithelial Ovarian Tumors, Hanan S. Abdel Hamid, Sherien A. Mohamed, Suzan M. Talaat, Zaineb Y. Mohieldin

Journal of Medicine in Scientific Research

Background and objectives Epithelial ovarian cancer (OC) is a clinically, morphologically, and molecularly heterogeneous disease. Estrogen receptor (ER) β is highly represented in normal ovarian epithelial cells and benign tumors, but ERα is the main form expressed in OC. ERα-positive OC had a favorable outcome. Progesterone receptor (PR) expression in ovarian tumors is a good prognostic marker associated with longer progression-free survival. Human epidermal growth-factor receptor (HER) 2 expression is associated with a worse prognosis. The aim of the study was to evaluate immunohistochemical (IHC) expression of ER, PR, and HER2/neu in ovarian epithelial tumors and to correlate their expression …

Solid Pseudopapillary Epithelial Neoplasm Of The Pancreas: A Case Report, Indu B. Dubey, Sajal Gupta, Shivani Paruthy, Vimal Bhandari

Journal of Medicine in Scientific Research

Solid pseudopapillary epithelial neoplasm (SPEN) of the pancreas is a rare neoplasm of the pancreas accounting for only 0.17–2.7% of all pancreatic neoplasms, often detected initially on imaging. Despite advances in imaging, pseudocysts and other cystic neoplasms feature in the differential diagnosis. We report a case of solid pseudopapillary epithelial neoplasm in a young female who presented with a progressively increasing abdominal lump in whom the diagnosis was considered based on imaging studies. She underwent exploratory laparotomy, pancreaticoduodenectomy, pancreaticojejunostomy, hepaticojejunostomy, gastrojejunostomy, and made an uneventful recovery in the postoperative period. Histopathological examination and immunohistochemistry confirmed the diagnosis. This case highlights …

Natural Resource System Size Can Be Used For Managing Recreational Use, Derek S. Kane, Kevin L. Pope, Keith D. Koupal, Mark A. Pegg, Christopher J. Chizinski, Mark A. Kaemingk

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Outdoor recreation provides societal benefits that are often measured by the amount of use natural resource systems receive. Still, the amount of resource use natural resource systems receive is often unknown or unstudied. Monitoring and quantifying resource use is often logistically difficult and costly but is paramount to optimize societal benefits. Identifying a simple and readily available metric that can indicate the quantity of recreational use of natural resource systems would benefit natural resource management. Using recreational angler participation data during an 11-year study period from 73 public waterbodies in Nebraska, USA, we developed a resource size-use model that demonstrates …

The International Society of Hepatic Sinusoidal Research (ISHSR) commissioned this working group to review the currently available in vitro liver models and describe the advantages and disadvantages of each in the context of evaluating their use for the study of …

Towards An Equitable Review Of Pre-Embryo And Divorce Disputes For Women, Lilah Kleban

Northwestern Journal of Law & Social Policy

Pre-embryos, procured through in-vitro fertilization (IVF), become a source of dispute when couples divorce or separate before using them. Particularly, couples may fight over who has decision-making power to use or not use the frozen pre-embryos for pregnancy. State courts across jurisdictions typically apply one of three categorical approaches: disposition contracts, contemporaneous mutual consent, or a balancing interests test. Each approach fails to provide courts with structures to fully evaluate each party’s interests at the time of dispute and account for inherent sex and gender differences that impact their stakes in the dispute. This Note proposes a modified balancing test …

Hong Kong has implemented stringent public health and social measures (PHSMs) to curb each of the four COVID-19 epidemic waves since January 2020. The third wave between July and September 2020 was brought under control within 2 m, while the fourth wave starting from the end of October 2020 has taken longer to bring under control and lasted at least 5 mo. Here, we report the pandemic fatigue as one of the potential reasons for the reduced impact of PHSMs on transmission in the fourth wave. We contacted either 500 or 1,000 local residents through weekly random-digit dialing of landlines …

Institute of Emerging Health Professions Faculty Papers

Adulteration is a well-known practice of drug manufacturers at different stages of drug production. The intentional addition of active ingredients to adulterate the primary drug may enhance or mask pharmacological effects or may produce more potent drugs to increase the number of available doses and the dealer's profit. Adulterants found in different drugs change over time in response to different factors. A systematic literature search in PubMed and Scopus databases and official international organizations' websites according to PRISMA guidelines was performed. A total of 724 studies were initially screened, with 145 articles from PubMed and 462 from Scopus excluded according …
