This article is the product of a review of historical-critical literature that analyzes the global historical events during the 20th century that made the emergence and consolidation of the medical rehabilitation professions possible and an examination of the ways in which these professions approach childhood. The analysis of and reflections upon the reviewed documents are outlined below accord...

[1] In many climate model simulations using realistic, time-varying climate change forcing agents for the 20th and 21st centuries, the North Atlantic thermohaline circulation (THC) weakens in the 21st century, with little change in the 20th century. Here we use a comprehensive climate model to explore the impact of various climate change forcing agents on the THC. We conduct ensembles of integr...

[1] Observational analyses have documented increases in global ocean temperature, heat content, and sea level in the 20th century. Previous studies argued that the observed ocean warming is a response to increasing greenhouse gases. We use a new climate model to decompose simulated ocean temperature changes into components attributable to subsets of anthropogenic and natural influences. The mod...

This study aims to present the origins and the historical evolution of fine-needle aspiration biopsy and to also underline its importance in the history of modern cytology. The article focuses on the advances made in the 20th century that have led to the modern techniques associated with the procedure. The authors conducted a thorough review of early reports on needle biopsy, particularly those...

Stereological studies were performed on 20 pairs of adrenal glands of human foetuses. The volume of particular adrenocortical zones, average cell volume and number of parenchymal cells were calculated. In 50 to 320 mm crown-rump length (C.-R.L.) foetuses (9-38 weeks of the intra-uterine life) an exponential increase in adrenal gland weight was found. If compared with the earlier period, the rat...

A global collection of high temporally resolved ice-core-derived dO records is examined to assess whether the proxy records are consistent with contemporaneous observed temperature variations in their respective regions. This is prerequisite to using the older parts of the proxy (dO) records to assess whether 20th-century temperatures remain within the range of longer-term natural variability. ...

BACKGROUND/AIM This study aimed to evaluate the effects of balneotherapy on acute, process-related, and cumulative peripheral cardiac responses and pulmonary functions in patients with musculoskeletal disorders. MATERIALS AND METHODS Ninety-eight patients with musculoskeletal disorders referred to physiotherapy with balneotherapy were recruited. The patients received balneotherapy for 20 min ...

Transcranial magnetic stimulation has become an important field for both research in neuroscience and for therapy since Barker in 1985 showed that it was possible to stimulate the human motor cortex with an electromagnet. Today for instance, transcranial magnetic stimulation can be used to measure nerve conduction velocities and to create virtual lesions in the brain. The latter option creates ...
