Laparoscopic-Assisted Vaginal Hysterectomy With Dense Bladder Adhesions and Absent Cervix: A Case Report With a Descriptive Video of the Entire Procedure.

Hysterectomy is one of the most frequently performed surgical procedures in the United States. Hysterectomy for benign gynecological reasons can be performed through several approaches: abdominal, laparoscopic, laparoscopically assisted vaginal, robotic-assisted, and vaginal natural orifice hysterectomy. The choice of approach is strongly influenced by factors such as previous procedures, safety, and recovery process.

DNA Methylation Biomarkers Predict Objective Responses to PD-1/PD-L1 Inhibition Blockade.

Immune checkpoint inhibitor (ICI) treatment could bring long-lasting clinical benefits to patients with metastatic cancer. However, only a small proportion of patients respond to PD-1/PD-L1 blockade, so predictive biomarkers are needed. Here, based on DNA methylation profiles and the objective response rates (ORRs) of PD-1/PD-L1 inhibition therapy, we identified 269 CpG sites and developed an initial CpG-based model by Lasso to predict ORRs.

Pooled Genomic Screens Identify Anti-apoptotic Genes as Targetable Mediators of Chemotherapy Resistance in Ovarian Cancer.

High-grade serous ovarian cancer (HGSOC) is often sensitive to initial treatment with platinum and taxane combination chemotherapy, but most patients relapse with chemotherapy-resistant disease. To systematically identify genes modulating chemotherapy response, we performed pooled functional genomic screens in HGSOC cell lines treated with cisplatin, paclitaxel, or cisplatin plus paclitaxel. Genes in the intrinsic pathway of apoptosis were among the top candidate resistance genes in both gain-of-function and loss-of-function screens.

Ex Uno Plura: Differential Labeling of Phospholipid Biosynthetic Pathways with a Single Bioorthogonal Alcohol.

Imaging approaches that track biological molecules within cells are essential tools in modern biochemistry. Lipids are particularly challenging to visualize, as they are not directly genetically encoded. Phospholipids, the most abundant subgroup of lipids, are structurally diverse and accomplish many cellular functions, acting as major structural components of membranes and as signaling molecules that regulate cell growth, division, apoptosis, cytoskeletal dynamics, and numerous other physiological processes.

[Effect of Manual Acupuncture Intervention on Levels of 5-HTT, 5-HTR, NEαR of Brain Tissues in Rats with Post-stroke Depression].

Objective: To observe the effect of manual acupuncture intervention on serotonin transporter (5-HTT), 5-HT 1 A receptor (5-HTR), norepinephrine (NE) alpha receptor 2 (NEαR) protein of brain tissues in rats with post-stroke depression (PSD).

Methods: Forty SD rats were randomly divided into normal group, model group, medication group and acupuncture group, with 10 rats in each. The PSD model was established by the combination of middle cerebral artery occlusion and chronic non- predictable mild stress.

Progress and challenges in the use of latent HIV-1 reactivating agents.

Highly active antiretroviral therapy (HAART) can effectively suppress the replication of human immunodeficiency virus-1 (HIV-1) and block disease progression. However, chronic HIV-1 infection remains incurable due to the persistence of a viral reservoir, including the transcriptionally silent provirus in CD4(+) memory T cells and the sanctuary sites that are inaccessible to drugs. Reactivation and the subsequent elimination of latent virus through virus-specific cytotoxic effects or host immune responses are critical strategies for combating the disease.

SNP rs2470152 in CYP19 is correlated to aromatase activity in Chinese polycystic ovary syndrome patients.

CYP19 encodes aromatase, a key enzyme essential for estrogen biosynthesis. Single nucleotide polymorphism (SNP) rs2470152 in CYP19 is associated with serum estradiol (E2) level and the E2/T (estradiol/testosterone) ratio. A case‑control study including 661 individuals [364 polycystic ovary syndrome (PCOS) patients and 297 controls] was conducted to assess the association of SNP rs2470152 with PCOS.

Polymorphisms of the HSD17B6 and HSD17B5 genes in Chinese women with polycystic ovary syndrome.

Objectives: To investigate the polymorphisms of the 17β-hydroxysteroid dehydrogenase type 5 and type 6 (HSD17B5 and HSD17B6) genes in Chinese women with polycystic ovary syndrome (PCOS).

Methods: Two hundred twenty-two PCOS patients and 283 controls were studied. Menarche age was recorded.

Association between CYP19 gene SNP rs2414096 polymorphism and polycystic ovary syndrome in Chinese women.

Background: Several studies have reported the association of the SNP rs2414096 in the CYP19 gene with hyperandrogenism, which is one of the clinical manifestations of polycystic ovary syndrome (PCOS). These studies suggest that SNP rs2414096 may be involved in the etiopathogenisis of PCOS. To investigate whetherthe CYP19 gene SNP rs2414096 polymorphism is associated with the susceptibility to PCOS, we designed a case-controlled association study including 684 individuals.

Response of IGF and IL-6 to ovarian stimulation in PCOS and normal women.

The objective of the present study was to investigate the response patterns of insulin-like growth factors (IGFs) and interleukin-6 (IL-6) to ovarian stimulation within 24 h in patients with polycystic ovary syndrome (PCOS) in comparison with normally ovulating women. This controlled prospective clinical study involved 60 women who attended an infertility clinic. For the induction of the ovarian stimulation, fifty-two patients with PCOS and eight control cases were injected with human menopause gonadotropin (hMG) and human chorionic gonadotropin (hCG) during the early follicular phase of the natural or induced menstrual cycle.

Quantitative phase determination for macromolecular crystals using stereoscopic multibeam imaging.

Without invoking anomalous dispersion and heavy-atom derivatives, it is demonstrated that it is possible to directly determine the phases of a large number of reflections collected in a short time from macromolecular crystals using a stereoscopic oscillation-crystal imaging technique, in a multibeam diffraction geometry, where two crystallographic axes in opposite directions are employed as the rotation axes. The intensity profiles (distributions) of the diffraction spots versus the varying tilt Bragg angle of the rotation axis in the two stereoscopically related images yield quantitative phase information. Many multiple diffraction profiles of tetragonal lysozyme and an unknown protein structure are obtained at the rate of 100 profiles per 30 min of X-ray exposure.
