Conception may involve natural or assisted reproductive technologies.
This MeSH term provides a concise, informative overview of the biological process by which a new individual is prpouced.

Comorbid conditions included in the Bateman comorbidity index were defined using the ICD‐9‐CM (Clinical Modification) codes specified in Bateman's original article in the physician claims data and were converted to ICD‐10‐CA (Canadian Modification) codes for use in the hospitalisation and emergency room data (Appendix S1, see Supporting Information). Comorbidity scores were derived by searching all coding positions (up to 25, 10 and three diagnostic codes, respectively, are allowed in hospitalisation, emergency room and physician billing data) for an ICD code of interest to determine whether a particular comorbidity was present, multiplying by the weights derived by Bateman et al. (see Table
The prevalence of individual comorbidities and the overall comorbidity score were assessed by reporting source (all healthcare contacts, hospitalisation records only and delivery records only). The kappa statistic was used to examine the agreement between data sources for comorbidities that affected at least five women. The discrimination of the comorbidity index was assessed in each reporting source by constructing logistic regression models predicting either maternal end‐organ damage or extended length of stay for delivery using the continuous comorbidity score as the exposure variable and measuring AUC. The stratification capacity (proportion of women categorised as low and high risk) was assessed by examining the proportion of women allocated to each score, and calibration accuracy (correlation between predicted and observed outcomes) was assessed by examining the Brier score (the sum of the average squared error difference between the forecasted and observed outcome, with ‘0’ representing perfect forecasting) and what proportion of women in each comorbidity category experienced end‐organ damage or an extended length of stay for delivery. Finally, odds ratios and 95% CIs (derived from logistic regression) were used to illustrate the association between the comorbidity index and each outcome of interest. All analyses were conducted using Stata 12 SE (Stata Corp., College Station, TX, USA).
Participants gave written informed consent before data collection. The study was approved by the institutional review boards of the hospitals where participants were recruited, the National Institute of Public Health of Mexico, Brigham and Women’s Hospital, Harvard School of Public Health, and the University of Michigan.
As genetic subgroups of a population defined by an IV represent subpopulations with long-term average differences in the exposure of interest,31 (link) the causal effects estimated in a Mendelian randomization analysis represent long-term relationships, equivalent to a randomized trial where the intervention is made at conception. As such, changes in the effects of the exposure and mediator over time and feedback between the exposure and mediator cannot be addressed by a conventional Mendelian randomization analysis. This has consequences for the interpretation of all Mendelian randomization estimates,32 (link) and particularly in a mediation setting, where a ‘bidirectional’ causal relationship between X and Z may reflect an effect of (say) X on Z in early life, and Z on X in later life. Ideally in mediation analyses, biological knowledge should be used to provide a causal ordering of the exposure, mediator and disease. Where this is not possible, reciprocal Mendelian randomization approaches may provide evidence on the direction of causal effects, although all such estimates rely on the assumption that these effects do not vary in direction over time.

Example 27
The binding of CIBN and CRY2 in cells expressing CIBN-EGFP-CD9 and Nucleic acid-binding protein-mCherry-Cry2 at 488 nm wavelength blue light, and the loading of Nucleic acid-binding protein within the exosome is evaluated.
For the massive production of Nucleic acid-binding protein-loaded exosomes, cells stably expressing CIBN-EGFP-CD9 gene and Nucleic acid-binding protein-mCherry-CRY2 gene are established, and exosomes are isolated and purified by Tangential Flow Filtration (TFF) method from culture supernatant.
Functional analysis of Nucleic acid-binding protein-loaded exosomes is performed in target cells:
Target cells are treated with Nucleic acid-binding protein-loaded exosomes to show the functional activity.
Animal models are administered with Nucleic acid-binding protein-loaded exosomes by i.p. or i.v. to show therapeutic effect.

More about "Conception"
This biological process can occur naturally or through assisted reproductive technologies (ARTs) such as in vitro fertilization (IVF) and intrauterine insemination (IUI).
The term conception is often used interchangeably with terms like fertilization, implantation, and pregnancy.
Fertilization is the fusion of the male sperm and female egg, while implantation is the attachment of the fertilized egg to the uterine lining.
Conception can be influenced by various factors, including age, health conditions, genetics, and environmental factors.
Conditions like polycystic ovary syndrome (PCOS), endometriosis, and male factor infertility can impact the conception process.
Assisted reproductive technologies, such as SAS 9.4 (Statistical Analysis System) and Penicillin/streptomycin, can be used to support the conception process.
C57BL/6J mice and B6.Cg-Tg (HIST1H2BB/EGFP) 1Pa/J mice are commonly used in research related to conception and embryo development.
Additionally, the QIAamp DNA Mini Kit and FBS (Fetal Bovine Serum) may be utilized in various laboratory procedures related to conception and reproductive biology.
The C57BL/6J mouse strain and GlutaMAX supplement are also commonly used in such research.
