Nutritional index in relation to prognosis of endometrial cancer.

Evaluate the prognostic value of the prognostic nutritional index (PNI) in patients with endometrial cancer (EC). Laboratory and clinicopathological data from 370 patients who were diagnosed with EC between January 2010 and December 2021 were reviewed. The PNI was analyzed for correlations with recurrence and survival.

Carboxylated Poly-L-lysine Potentially Reduces Human Sperm DNA Fragmentation after Freeze-Thawing, and Its Function Is Enhanced by Low-Dose Resveratrol.

Sperm DNA fragmentation (SDF) that occurs during the freezing-thawing of sperm may negatively impact the treatment outcomes of assisted reproductive technologies (ART). In a previous study, we developed a human sperm cryopreservation reagent containing carboxylated poly-L-lysine (CPLL) that reduced SDF after freeze-thawing compared with clinically popular cryopreservation reagents containing human serum albumin. However, it is unclear whether CPLL reduces SDF, as it differed from the constituents of the commercial cryopreservation reagents used for comparison.

Robotic surgery in Gynecology: the present and the future.

Since its introduction, laparoscopic surgery has been often preferred over open surgery in obstetrics and gynecology due to its advantages, such as less bleeding, lower incidence of adhesions, reduced postoperative pain, short hospital stay, and quick return to daily life. However, in the case of complex surgeries, laparoscopy presented some limitations. Nonetheless, since the 1980s, medical robots have been introduced to overcome the technical limitations of laparoscopy and start a new age for minimally invasive surgery.

Improved fertility of frozen-thawed porcine spermatozoa with 3,3-dimethylglutaric anhydride poly-L-lysine as a novel cryoprotectant.

In this study, we determined the efficacy of 3,3-dimethylglutaric anhydride poly-L-lysine (DMGA-PLL) as a cryoprotectant for porcine spermatozoa. Porcine spermatozoa were cryopreserved in a freezing extender containing 3% (v/v) glycerol and various concentrations of DMGA-PLL. At 12 h after thawing, the motility index of spermatozoa cryopreserved with 0.

Cryopreservation of pig spermatozoa using carboxylated poly-L-lysine as cryoprotectant.

In this study, we cryopreserved pig spermatozoa using carboxylated poly-L-lysine (CPLL) as the cryoprotectant to determine its efficacy. Pig spermatozoa were placed in a freezing extender containing 3% (v/v) glycerol and different CPLL concentrations. The motility indices of the spermatozoa cryopreserved with 0.

Carboxylated Poly-l-Lysine as a Macromolecular Cryoprotective Agent Enables the Development of Defined and Xeno-Free Human Sperm Cryopreservation Reagents.

In human sperm cryopreservation, test yolk buffer and human serum albumin have been used as permeating macromolecular-weight cryoprotectants. In clinical reproductive medicine, human serum albumin is frequently used because of low risks of zoonoses and allergic reactions. However, the risk of allogeneic infectious diseases exists, and the supply may be unstable because human serum albumin is derived from human blood.

A liquid culture cancer spheroid model reveals low PI3K/Akt pathway activity and low adhesiveness to the extracellular matrix.

Three-dimensional (3D) cultures of cancer cells in liquid without extracellular matrix (ECM) offer in vitro models for metastasising conditions such as those in vessels and effusion. However, liquid culturing is often hindered by cell adhesiveness, which causes large cell clumps. We previously described a liquid culture material, LA717, which prevents nonclonal cell adhesion and subsequent clumping, thus allowing clonal growth of spheroids in an anchorage-independent manner.

Utility of human papillomavirus L1 capsid protein and HPV test as prognostic markers for cervical intraepithelial neoplasia 2+ in women with persistent ASCUS /LSIL cervical cytology.

Efficient and highly predictive biomarkers reflecting the prognosis of persistent atypical squamous cells of unknown significance(ASCUS) and low grade squamous intraepithelial lesion(LSIL)s are unavailable and need to be developed urgently. We aimed to develop a predictive model for diagnosis of cervical intraepithelial neoplasia(CIN)2+ by analyzing the immunocytochemical expression of the HPV L1 capsid protein in patients with persistent ASCUS and LSIL with a high risk of HPV infection. : Cervical cytology samples comprising (70 ASCUS and 215 LSIL Pap smears) were analyzed.

Differences in autophagy-associated mRNAs in peritoneal fluid of patients with endometriosis and gynecologic cancers.

Endometriosis and gynecologic cancer show similar patterns of invasion. Little is known about the roles of autophagy in endometriosis and, to date, the expression of autophagy-associated mRNAs has not been compared in patients with endometriosis and gynecologic cancers. This study therefore compared the levels of expression of autophagy-associated mRNAs in patients with endometriosis and gynecologic cancers.

Cryoprotective effect of antifreeze polyamino-acid (Carboxylated Poly-l-Lysine) on bovine sperm: A technical note.

In this study, investigating Carboxylated Poly-l-Lysine (CPLL) for its effectiveness as a new cryoprotectant for bovine sperm is aimed. CPLL is an ampholytic polymer compound, has cryoprotective properties similar to those of anti-freeze protein. The cryopreservation medium used for control group consisted of 6.

Cryopreservation of bovine somatic cells using antifreeze polyamino-acid (carboxylated poly-L-lysine).

Carboxylated poly-L-lysine (CPLL) is an ampholytic polymer compound, obtained by converting 65 mol% of amino groups to carboxyl groups after synthesizing ε-poly-l-lysine aqueous solution and succinic anhydride. CPLL has cryoprotective properties similar to those of anti-freeze protein. The addition of CPLL to freezing medium has been reported to improve the post-thawing survival rate of murine cells, human induced pluripotent stem (iPS) cells, embryonic stem (ES) cells and embryos.
