In vitro breeding: application of embryonic stem cells to animal production.

Biol Reprod 2018 Dec 14. Epub 2018 Dec 14.

Department of Animal Science, University of California, Davis, CA.

Embryonic stem cells (ESCs) are derived from the inner cell mass of preimplantation blastocysts. For decades, attempts to efficiently derive ESCs in animal livestock species have been unsuccessful, but this goal has recently been achieved in cattle. Together with the recent reconstitution of the germ cell differentiation processes from ESCs in mice, these achievements open new avenues for the development of promising technologies oriented toward improving health, animal production and the environment.

Reducing the Complexity of Mathematical Models for the Plant Circadian Clock by Distributed Delays.

J Theor Biol 2018 Dec 11. Epub 2018 Dec 11.

Sainsbury Laboratory, University of Cambridge, Bateman Street, Cambridge, CB2 1LR, UK. Electronic address:

A major bottleneck in the modelling of biological networks is the parameter explosion problem - the exponential increase in the number of parameters that need to be optimised to data as the size of the model increases. Here, we address this problem in the context of the plant circadian clock by applying the method of distributed delays. We show that using this approach, the system architecture can be simplified efficiently - reducing the number of parameters - whilst still preserving the core mechanistic dynamics of the gene regulatory network.

The tubulin-associated unit (Tau) protein is an intrinsically disordered protein that plays a well-established role in promoting microtubule assembly and stabilization in neuronal axons at all stages of development. Identification of new interacting partners and different sub-cellular localizations of Tau in recent years led to the discovery of novel physiological functions in regulation of neuronal activity, neurogenesis, long-term depression, iron export and genomic integrity. In addition, Tau gene mutations, aberrant mRNA splicing and abnormal post-translational modifications, such as hyperphosphorylation, lead to formation of pathological, insoluble Tau aggregates that are a hallmark of neurodegenerative diseases, collectively known as tauopathies.

Novais, Department of Pediatric Orthopedic surgery, Boston Children's Hospital, Boston, MA, USA K. Ziebarth, Department of Pediatric Surgery, Inselspital, University of Bern, Bern, Switzerland.

Background: Prophylactic pinning of the asymptomatic and normal-appearing contralateral hip in patients with unilateral slipped capital femoral epiphysis (SCFE) remains controversial. Understanding the minimal 10-year clinical, functional, and radiographic outcomes of the contralateral asymptomatic hip in unilateral SCFE may be helpful in the decision regarding whether the benefits associated with potentially preventing a SCFE are outweighed by the risk of additional surgery.

Questions/purposes: Among patients with SCFE treated with prophylactic pinning of the asymptomatic and contralateral hip, we sought (1) to determine the complications and reoperations; (2) to evaluate the development of cam deformities and the frequency and severity of osteoarthritis progression; and (3) to characterize hip pain and function as measured by the Harris hip score (HHS) and the Hip Disability and Osteoarthritis Outcome Score (HOOS) at minimal 10-year followup.

Is diet management helpful in familial hypercholesterolemia?

Authors:
Samuel S Gidding

Curr Opin Clin Nutr Metab Care 2018 Dec 13. Epub 2018 Dec 13.

FH Foundation, Pasadena, California, USA.

Purpose Of Review: Familial hypercholesterolemia is a genetic condition where low-density lipoprotein (LDL) receptor defects cause severe elevations of LDL cholesterol. As significant LDL-lowering effects are needed, medication is considered the cornerstone of therapy, and dietary therapy has received less emphasis. This review will re-visit older studies of diet intervention and new insights from genetic and mechanistic studies to determine the value of diet management for familial hypercholesterolemia patients.

Alcohol and gastrointestinal cancers.

Curr Opin Gastroenterol 2018 Dec 12. Epub 2018 Dec 12.

Pancreato-Biliary Endoscopy Division and Endosonography Division, Pancreas Translational and Clinical Research Centre, San Raffaele Scientific Institute, Vita Salute San Raffaele University, Milan.

Purpose Of Review: Alcohol is a type I carcinogen and the WHO stated that it caused 5% of all deaths in 2016, of which 13% because of cancers. Among digestive tract cancers, this association is clear for esophageal, liver and colorectal cancer, and more debated for gastric and pancreatic cancer. The present review will revise recent evidence on epidemiologic association and mechanisms linking alcohol with the risk of esophageal, gastric, colorectal and pancreatic cancers. Read More

Diet and colon: what matters?

Curr Opin Gastroenterol 2018 Dec 12. Epub 2018 Dec 12.

Division of Hematology and Oncology, Department of Medicine, Medical College of Wisconsin, Milwaukee, Wisconsin.

Purpose Of Review: Colorectal cancer (CRC) is one of the most common cancers and the fourth leading cause of cancer-related deaths worldwide. Diet has a significant impact on the risk of developing CRC, but though processed meat is a known positive contributor, the effects of other dietary components are largely mixed. This review focuses on dietary patterns to describe the complexity of dietary diversity and overall food consumption and to examine the relationship between dietary patterns and risk of CRC.

Replication of newly proposed TNM staging system for medullary thyroid carcinoma: a nationwide study.

Endocr Connect 2018 Dec 1. Epub 2018 Dec 1.

C Godballe, Department of ORL Head and Neck Surgery and Audiology, Odense University Hospital, Odense, Denmark.

A recent study proposed new TNM groupings for better survival discrimination among stage groups for medullary thyroid carcinoma (MTC) and validated these groupings in a population-based cohort in the United States. However, it is unknown how well the groupings perform in populations outside the United States. Consequently, we conducted the first population-based study aiming to evaluate if the recently proposed TNM groupings provide better survival discrimination than the current American Joint Committee on Cancer (AJCC) TNM staging system (seventh and eighth edition) in a nationwide MTC cohort outside the United States.

Decrease in American birth rates makes it imperative for the United States to implement state mandated fertility coverage.

J Med Econ 2018 Dec 14:1-5. Epub 2018 Dec 14.

a McGill University Reproductive Center , 888 Boulevard de Maisonneuve East , Montréal , QC H2L 4S8 , Quebec , Canada.

In recent years, the prevalence of infertility has increased due to delayed child bearing and increase in the rate of male infertility. Given the high cost of fertility treatment, this option is not valid for families with low income, and those who can afford it usually choose to have multiple embryo transfers, which has led to an increase in multiple birth rates and increase in the cost of perinatal care. Due to the expected increase in infertility and decrease in the national live birth rate, the United States should set a plan to fund infertility treatment and lead a policy for single embryo transfer.

False memory at short and long term.

J Exp Psychol Gen 2018 Dec 13. Epub 2018 Dec 13.

Department of Psychology.

False memories are well-established long-term memory (LTM) phenomena. Recent reports of false recognition at short term suggest that working memory (WM) could also give rise to false memories, supporting the unitary view of memory. Alternatively, we hypothesized that the emergence of false memories at short term results from the impairment of WM maintenance, memory performance relying then on LTM. Read More
