A New Framework and Software to Estimate Time-Varying Reproduction Numbers During Epidemics

American Journal of Epidemiology, 2013
The quantification of transmissibility during epidemics is essential to designing and adjusting public health responses. Transmissibility can be measured by the reproduction number R, the average number of secondary cases caused by an infected individual.

Estimating the effective reproduction number of the 2019-nCoV in China

medRxiv, 2020
We estimate the effective reproduction number for 2019-nCoV based on the daily reported cases from China CDC. The results indicate that 2019-nCoV has a higher effective reproduction number than SARS with a comparable fatality rate.

Association of skewed X-chromosome inactivation with FMR1 CGG repeat length and anti-Mullerian hormone levels: a cohort study

Reproductive Biology and Endocrinology, 2017
Background Premutation range CGGn repeats of the FMR1 gene denote risk toward primary ovarian insufficiency (POI), also called premature ovarian failure (POF).

The Importance of Leptin to Reproduction.

Endocrinology, 2020
A healthy nutritional state is required for all aspects of reproduction and signaled by the adipokine leptin. Leptin acts in a relatively narrow concentration range; too much or too little will compromise fertility.

New national outcome data on fresh versus cryopreserved donor oocytes

Journal of Ovarian Research, 2018
Background Improvements in oocyte cryopreservation techniques and establishment of cryopreserved donor oocyte banks have led to improved access to and lower cost of donor oocytes, upending the traditional practice of fresh oocyte donation.

Smell and taste disorders in pregnant women with COVID-19

Acta Biomedica Scientifica, 2022
Background. Smell disorder is a recognized clinical symptom of COVID-19 infection. The problem of the loss of sense of smell in the structure of COVID-19 pathogenesis during pregnancy remains unresolved.   The aim of the study.

Probiotic consortiums: Structure and antagonistic activity against opportunistic bacteria and human normobiota (using the example of Escherichia coli) in vitro

Acta Biomedica Scientifica, 2023
Background. Using probiotic preparations based on consortia of microorganisms not only helps to restore the balance of the intestinal microbiota, but also increases the therapeutic effect of probiotics. Promising sources for obtaining probiotic consortia

Global dynamics of a periodic SEIRS model with general incidence rate [PDF]

, 2017
We consider a family of periodic SEIRS epidemic models with a fairly general incidence rate and it is shown the basic reproduction number determines the global dynamics of the models and it is a threshold parameter for persistence.
