Individual male rats may systematically display or not copulatory behavior when paired with receptive females. Although these phenotypes are associated with differences in brain organization and function, they might also do so at the level of the reproductive organs. We then used high performance liquid chromatography to quantify serotonin concentration and the activity of tryptophan hydroxylase in the reproductive organs of copulator and non-copulator males. Sexual behavior display was compared between groups and parameters of fertility and reproductive fitness were determined for copulator males. Copulator males had higher concentrations of serotonin in the epididymis, testicle and ventral prostate than their non-copulator counterparts, as it was found for epididymal and testicular tryptophan hydroxylase activity. However, preliminary data shows that serotonin elevation occurs in copulator males only until they have accumulated several sexual encounters, so it might be a response to genital gratification or sexual rewarding. Interestingly, only epididymal serotonin concentration correlated with reproductive fitness, offspring number, mating success and seminal plug volume in copulator males. Our results support that copulator and non-copulator male rats feature a phenotype-specific serotoninergic tone in the epididymis, testicle and ventral prostate gland. The observation documenting that epididymal serotonin concentration correlated with parameters that monitor male fertility and reproductive fitness in copulator males predicts that epididymal factors increase their chances of parenting offspring.

The Social Determinants of Health in Relation to Sexually Transmitted Infections in Maricopa County Arizona

引用

Advances in Infectious Diseases 2022年第2期12卷 328-336页

作者： Benjamin Picciano Andrea Vizcaino rosa angelica Hernandez Francisco Javier Vizcaino Carla Segura Coutino Alonso Trevino IV Javier Paz International University of the Health Sciences Basseterre Saint Kitts and Nevis School of Medicine Universidad Autónoma de Guadalajara Guadalajara Mexico

Based on the information that was collected on the County Health Rankings website [1], one of the top health concerns for Maricopa County was sexually transmitted infections or STIs. A big concern with STIs is this is not a common subject explored in educational settings or addressed socially. There are many organizations, including the CDC, that have access to materials, there is limited distribution of the educational content. Therefore, the public is not well informed and lacks the information to make educated decisions. The areas with insufficiencies are knowledge of the disease processes, prevention, and treatment.

Role of the Zinc Nutritional Status on Main Physiological Bioindicators of the Pecan Tree

Agricultural Sciences 2017年第12期8卷 1327-1336页

The purpose of this study was to analyze the effect of Zn nutritional status on the content of pigments, nonstructural carbohydrates, foliage proteins and amino acids of the pecan tree, as possible bioindicators of Zn deficiency. The experimental design was completely random with three Zn nutritional statuses: Normal, Intermediate and Deficient, being selected considering visual symptomatology. On all three nutritional statuses, the concentration of photosynthetic pigments was determined as well as of total soluble proteins and amino acids. Obtained results indicate that Zn deficient nutritional status was characterized by minimum photosynthetic pigment, protein concentrations, maximum amino acid and nonstructural carbohydrate concentrations. While the normal Zn nutritional status presented maximum photosynthetic pigments, proteins concentrations, minimum amino acids and carbohydrate concentrations. On the other hand, intermediate Zn nutritional status was characterized by a medium level between the other two Zn nutritional statuses. Finally, we stress the fact that pigments, proteins, amino acids and nonstructural carbohydrates may be good physiological indicators related to Zn nutritional status on pecan trees.

Esophagogastric Reconstruction in Cobra-Head Shape with Toupet-Like Partial Anti-Reflux Technique for Resection of Proximal Gastric Tumors. Experience with Three Cases from a Non-Asian Population

Background: Proximal gastrectomy is a rarely performed procedure but a feasible option in benign tumors and malignant neoplasms in the proximal third of the stomach since novel options of reconstructions are available nowadays with fewer long-term sequels. Methods: Report of three cases of proximal gastric gastrointestinal stromal tumors (GIST), with a description of its presentation, histological characteristics, and follow-up after being treated with proximal gastrectomy with cobra head reconstruction. Results: Case 1: A 62-year-old woman with epigastric pain of four months with endoscopic evidence of a cardia GIST. The surgery was performed without complications. The histopathological report confirmed a fusiform GIST of 3.2 × 3 × 2.5 cm, stage IA. No adjuvant treatment was considered. An esophagogram showed no evidence of reflux and no stenosis, and no disease recurrence after 40-months follow-up. Case 2: A 66-year-old woman with dyspepsia and a palpable tumor in the epigastrium. The surgery was performed without complications. The pathology report confirmed a proximal gastric GIST of 13 × 8 × 7 cm, staged II. She received adjuvant treatment with imatinib for 36 months without recurrence and no reflux or stenosis. Case 3: A 55-year-old woman with intermittent hematemesis and right subscapular pain. The surgery was performed without complications. The histopathological report concluded that a GIST tumor of the cardia, 1.4 × 1.2 cm, staged IA. She was left in observation. At a 6-month follow-up, she does not report dysphagia, reflux, or stenosis, and no locoregional recurrence. Conclusions: Open and laparoscopic proximal gastrectomy is a safe therapeutic option for GIST. Furthermore, the reconstruction of the esophagus-gastro anastomosis in the cobra head after proximal gastrectomy is feasible and secure in our population, with good functional results in a short follow-up.

本研究的目的是在体内评价渗透树脂(IR)治疗釉质白垩斑(WSLs)的即时遮盖效果。研究对象为40名11~23岁的青少年和年轻成人.至少有一颗上颌或下颌恒前牙为活动性白垩斑(ICDAS得分为2分)。在渗透树脂治疗前.使用数字分光光度计(CIElab)对白垩斑和相邻完整釉质(SAE)的颜色进行评估。接着.依据生产商的使用说明对白垩斑应用渗透树脂技术(Icon).临床操作结束时评估渗透树脂的颜色。计算白垩斑和相邻完整釉质(WSL×SAE)、白垩斑和渗透树脂(WSL×IR)以及渗透树脂和相邻完整釉质(IR×SAE)间的颜色差异(△E),然后用单因素方差分析和Turkey’s检验进行分析。用t检验来比较相关样本白垩斑.相邻完整釉质和渗透树脂的L^*、a^*、b^*值(α=5%)。白垩斑和渗透树脂(WSL×IR)比较时△E=5.930.41.渗透树脂和相邻完整釉质间(IR×SAE)的△E=5.770.41.说明治疗后白垩斑的颜色发生改变.但与相邻完整釉质相比.渗透树脂不能完全掩饰白垩斑。相邻完整釉质的明度比渗透树脂高。由此可以得出如下结论:与相邻完整釉质相比.渗透树脂治疗不能遮盖白垩斑的颜色.但可以减弱釉质脱矿引起的变色。
