Objective:To evaluate the effectiveness of hematopoietic stem cell (HSC) on TNF-αexpression, spiral artery remodeling, and placental ***: The study used pregnant mice divided to five groups of treatment: Group 1, without treatment;Group 2, 1/12 LD50 of lead and Aquadest;Group 3, 1/16 LD50 of lead and Aquadest, Group 4, 1/12 LD50 of lead and 1×107 HSC;and group 5, 1/16 LD50 of lead and 1×107 HSC. Histopathology examination was performed to identify spiral artery remodeling. Immunohistochemistry analysis was conducted to characterize TNF-α expression and the apoptosis index. The data from all five groups were compared using the ANOVA ***:TNF-α expression differed significantly among the groups that were not exposed to lead, exposed to lead and exposed to lead after HSC treatment (P0.05).Conclusions:In lead-exposed pregnant mice, the administration of hematopoietic stem cell may decrease TNF-α expression, spiral artery remodeling, and placental apoptosis index but in the group of 1/16 LD50 of lead and HSC treatment, apoptosis index has no differences with those of control group.

A Comparative Study of the Recurrence Rate in Hypofractionated versus Conventional Postmastectomy Radiation in Breast Cancer

引用

Journal of Cancer Therapy 2021年第12期12卷 736-750页

作者： Aravindh Sivanandan Anand abul.Hussain Mirsa amina Basheer Department of Radiation Oncology Government Medical College Trivandrum India Department of Pharmacology Government Medical College Trivandrum India

Background: Treatment options available for breast cancer are Surgery [Breast conservation surgery (BCS) or Modified radical mastectomy (MRM)];Radiation treatment [Conventional radiation treatment or CRT and Hypofractionated radiation treatment or HRT] and Chemotherapy. In the postmastectomy or post lumpectomy setting, radiotherapy (RT) improves loco-regional control. CRT for breast includes 50 Gy in 25 fractions (2 Gy per fraction) and HRT includes 42.5 Gy in 16 fractions (2.7 Gy per fraction) or extreme hypofractionation like 26 Gy in 5 fractions. Alpha/beta value for breast is less, so HRT is ideal for breast. So, there will be good loco-regional control, without increased normal tissue damage. This study aims to identify recurrence rate and toxicity in breast cancer patients treated using conventional and hypofractionated postmastectomy radiotherapy among Indian population. Primary objective: To assess recurrence rate of disease in breast cancer patients treated using hypofractionated postmastectomy radiation and to compare it with breast cancer patients treated using conventional postmastectomy radiation. amily:Verdana;">Secondary objective

Advantages of using the CRISPR/Cas9 system of genome editing to investigate male reproductive mechanisms using mouse models

引用

Asian Journal of Andrology 2015年第4期17卷 623-627页

Gene disruption technology has long been beneficial for the study of male reproductive biology. However, because of the time and cost involved, this technology was not a viable method except in specialist laboratories. The advent of the CRISPR/Cas9 system ofgene disruption has ushered in a new era of genetic investigation. Now, it is possible to generate gene-disrupted mouse models in very tittle time and at very little cost. 1his Highlight article discusses the application of this technology to study the genetics of male fertility and looks at some of the future uses of this system that could be used to reveal the essential and nonessential genetic components of male reproductive mechanisms.

The 2nd Session of 2008 Workshop of Pakistan Academy of Sciences

作者： abul.Mukid Mohammad Mukaddes Mohammed Mahbubul Islam Department of Industrial and Production Engineering Shahjalal University of Science and TechnologySylhet Bangladesh

ADVENTURE on Windows is a collection of finite element modules including ADVENTUREolid ported to Microsoft Windows for use in a single CPU. It supports the iterative domain decomposition method with a preconditioner for the solution of linear equations. This paper analyzed 3 dimensional linear elastic stress problems and measured the performance of the finite element software ADVENTURE on Windows. A complete finite element analysis from CAD design to visualization was performed in this research successfully. Two simple models have been considered for the linear elastic problems. Computational results show the computation time, required memory, convergence criteria and some limitations of the software.

Current status and prospects of clinical proteomics studies on detection of colorectal cancer:Hopes and fears

引用

World Journal of Gastroenterology 2006年第41期12卷 6594-6601页

作者： ME de Noo RAEM Tollenaar am Deelder LH Bouwman Department of Surgery Leiden University Medical CenterLeidenThe Netherlands Biomolecular Mass Spectrometry Unit Department of ParasitologyLeiden University Medical CenterLeidenThe Netherlands

Colorectal adenocarcinoma （CRC） is the third most common type of cancer and the fourth most frequent cause of death due to cancer worldwide. Given the natural history of CRC, early diagnosis appears to be the most appropriate tool to reduce disease-related mortality. A field of recent interest is clinical proteomics, which was reported to lead to high sensitivity and specificities for early detection of several solid tumors. This emerging field uses mass spectrometry-based protein profiles/patterns of easy accessible body fluids to distinguish cancer from non-cancer patients. These discrepancies may be a result of：（i） proteins being abnormally produced or shed and added to the serum proteome, （2） proteins clipped or modified as a consequence of the disease process, or （3） proteins subtracted from the proteome owing to disease-related proteolytic degradation pathways. Therefore, protein pattern diagnostics would provide easy and reliable tools for detection of cancer. This paper focuses on the current status of clinical proteomics research in oncology and in colorectal cancer especially, and will reflect on pitfalls and fears in this relatively new area of clinical medicine, which are reproducibility issues and pre-analytical factors, statistical issues, and identification and nature of discriminating proteins/peptides.
