Lòng trắng trứng gồm 4 phần theo thứ tự như hình vẽ trên Lớp đầu tiên là lớp mỏng có tác dụng Lớp đặc, dày, hơi đục …thành phần chủ yếu của lòng trắng Lớp khí đặc, mỏng, mờ đục(bao quanh màng viteline của lòng đỏ. Hai đầu của lớp lòng trắng trong cùng này là hai dây đỡ lòng đỏ xoắn theo hai chiều ngược nhau để giữ lòng đỏ ở vị trí trung tâm và giữ đĩa phôi luôn ở vị trí hướng lên Protein ở lòng trắng đa số thuộc loại đơn giản, nằm ở trạng thái hòa tan và có đến 8 loại khác nhau, chủ yếu là albumin (gần 70%), ovomucoit (10%), globulin (7%), avidin (0,05%)... Protein của lòng trắng cũng có thành phần axit amin toàn diện như lòng đỏ. chất avidin của trứng còn kết hợp với biotin (còn gọi vitamin H) thành phức chất avidin - biotin làm cho cơ thể mất khả năng hấp thu biotin, dễ gây nên tình trạng cơ thể bị thiếu hụt vitamin H. Nhưng chỉ cần đun nóng tới 80oC thì men antitrypsin bị phá hủy và biotin cũng được giải phóng khỏi phức hợp avidin - biotin, ăn trứng an toàn và ngon lành. Lòng trắng trứng thì có thể ăn thoải mái bởi nó không có chất béo, cũng không có cholesterol.

Does the Market for Women's Labor Need Fixing?1989 •
I will start by reviewing the evidence that discrimination against women is currently serious and has important consequences for their pay and status. Some of this evidence is of a variety that economists do not commonly examine or take account of. On the assumption that at least some readers will agree that some remedies might be called for, I go on to look at the virtues and defects of the remedies most commonly proposed—affirmative action and administered wage realignment under the rubric of “pay equity” or “comparable worth.”

Nigeria relies on data from periodic resource-intensive surveys such as antenatal HIV seroprevalence sentinel surveys (ANC-HSS) and population-based National AIDS and Reproductive Health Surveys (NARHS) for its HIV control efforts. Nigeria has not explored the use of readily available routine programmatic data (RPD) to easily inform and monitor epidemic control efforts at local settings in near real time. This study aimed to determine the utility of RPDs (Prevention of Mother-To-Child Transmission [PMTCT] and HIV Testing and Counseling [HTC]) as a proxy for monitoring HIV epidemic in Nigeria. Using World Health Organization 12 step triangulation procedures, we compared state-level seropositivity data from PMTCT and HTC programs to HIV prevalence data from NARHS and ANC-HSS reports in relevant pairs from 2010 to 2014 in Nigeria. The study population was pregnant women and general population. We abstracted relevant data from PEPFAR Nigeria data source and published national survey rep...

Bullying y factores de riesgo para la salud en estudiantes de secundaria2010 •
La convivencia entre escolares se está convirtiendo en un grave problema en nuestras aulas. Los docentes tienen serios problemas para hacer frente a conductas perturbadoras entre los estudiantes (agresiones verbales y físicas, consumo de drogas, etc.). Por otra parte, los estudios apuntan que el consumo de drogas forma parte de la vida de muchos adolescentes, considerando que estamos ante una “normalización” de su consumo. El objetivo de nuestra investigación es indagar las posibles asociaciones entre los implicados en bullying y la realización de determinadas conductas de riesgo para la salud (por ejemplo, consumo de sustancias adictivas). Sobre una muestra de 886 estudiantes de Enseñanza Secundaria Obligatoria, se administraron los instrumentos de evaluación siguientes: el Test BULL-S y una encuesta elaborada ah hoc sobre conductas de riesgo para la salud. Los resultados indican que el 20.8% están implicados en bullying en sus distintos roles. Entre las variables seleccionadas, lo...

: Industry players are encouraged to automate as a result of technological advancements. However, due to lack of finances several businesses continue to require human labor in the production process, particularly in the operation of transferring items . Transportation activities at Dock 16 Ilir in Palembang City, starts with delivering items from the shop to the ship or vice versa by utilizing human strength in less ergonomic work positions with little consideration for the weight of the load. Whencarrying goods , the body is bent, the neck is bent, and the arms are distant from the body, putting the body at a very high risk of injury. This type of working position causes muscle aches ranging from mild to severe. The personnel seen in this investigation were rice transporters and cement transporters. The aim of this study is to quantify the workload and provide a design tool to help lessen worker concerns. The Nordic Body Map, Rapid Upper Limb Assessment (RULA), and Ovako Workin...

Genome-Wide CpG Island Profiling of Intraductal Papillary Mucinous Neoplasms of the Pancreas2011 •
Purpose: Intraductal papillary mucinous neoplasms (IPMN) are precursors to infiltrating pancreatic ductal adenocarcinomas. Widespread epigenetic alterations are characteristic of many cancers, yet few studies have systematically analyzed epigenetic alterations of neoplastic precursors. Our goal was to conduct genome-wide CpG island methylation profiling to identify aberrantly methylated loci in IPMNs. Experimental Design: We compared the CpG island methylation profiles of six IPMNs to normal primary pancreatic duct samples using methylation CpG island amplification (MCA) and Agilent CpG island microarray (MCAM) analysis. When selected 13 genes identified as differentially methylated by MCAM for methylation-specific PCR (MSP) analysis in an independent set of IPMNs and normal pancreas samples and conducted expression analysis of selected genes. Results: We identified 2,259 loci as differentially methylated in at least one of six IPMNs including 245 genes hypermethylated in IPMNs with...
